The utility model discloses the waterproof simple structure of LED display screen, water - proof effects is good, and waterproof rank can reach IPx5.

Based on which, it is necessary to provide a waterproof assembly and a display screen, aiming at solving the problem that the thick or thin waterproof rubber ring of the display module fixed by magnetic suction will cause a gap between the waterproof rubber ring and the module, resulting in poor waterproof effect.

A waterproof assembly, applied to a display screen, the display screen including a cabinet and a display module connected with the cabinet, an installation space being defined between the display module and the cabinet, wherein the waterproof assembly is disposed in the installation space and includes:
a bottom surface and a waterproof substrate protruded from the bottom surface along a first direction, the waterproof substrate including: two mounting surfaces disposed facing in a same direction; and at least one waterproof protrusion protruded from at least one of the two mounting surfaces and including:.

A communication opening is defined in the middle of the waterproof substrate, the protrusion body and the waterproof ribs are arranged around the communication opening.

At least one waterproof protrusion strip is provided on the other one of the two mounting surfaces of the waterproof substrate, the waterproof protrusion strip is spaced from the protrusion body, and the waterproof protrusion strip is arranged around the communication opening.

In one embodiment, a number of the waterproof protrusion is at least two.

In one embodiment, the waterproof ribs are evenly distributed on the connecting end surface respectively.

In one embodiment, a number of the waterproof ribs is two; and a distance between the two waterproof ribs gradually increases in the direction away from the connecting end surface.

In one embodiment, the two waterproof ribs are arranged symmetrically.

In one embodiment, the protrusion body and the waterproof ribs are both ring-shaped structures.

In one embodiment, a plurality of the waterproof protrusions extending in a same direction are provided on the same mounting surface of the waterproof substrate, and the plurality of the waterproof protrusions are arranged in ring shapes from inside to outside.

In one embodiment, the waterproof ribs, the at least one waterproof protrusion and the waterproof substrate are integrally formed.

The present application further provides a display screen, including a cabinet and a display module connected with the cabinet, and an installation space is defined between the display module and the cabinet. The display screen further includes the waterproof assembly according to any one of the above embodiments. The waterproof assembly is disposed in the installation space. At least one of the cabinet and the display module is abutted against the waterproof ribs.

In one embodiment, the mounting surface of the waterproof substrate facing the display module includes the at least one waterproof protrusion. The display module is abutted against the waterproof ribs. In one embodiment, at least one of the cabinet and the display module defines an embedded slot, and the waterproof assembly is embedded in the embedded slot.

In one embodiment, the display module includes a data interface. The waterproof substrate is a ring-shaped structure and surrounds the data interface.

In one embodiment, a surface of the display module in contact with the at least one waterproof protrusion is defined as a second abutting surface. The second abutting surface is inclined with respect to the mounting surface.

According to the above-mentioned waterproof assembly and display screen, a waterproof assembly is provided between the cabinet of the display screen and the display module of the display screen. The waterproof protrusion is easily deformed relative to the waterproof substrate. When the deformation is large, the waterproof effect is better, so that sealing and waterproof effects may be achieved by squeezing the waterproof protrusion and the display module, or squeezing the waterproof protrusion and cabinet, instead of squeezing the waterproof substrate and the display module, or squeezing the waterproof substrate and the cabinet.

Especially when the cabinet and the display module are connected by means of magnetic attraction, the reverse thrust of the waterproof protrusion on the cabinet or the display module is very small, which will not damage the magnetic attraction between the cabinet and the display module. Since it can be sealed and waterproofed only by the waterproof protrusion, the thickness of the waterproof substrate may be made relatively small, and there is no need to worry about the problem of poor waterproof effect due to a gap existed at the compression portion because of the insufficient thickness of the waterproof rubber ring. As a result, materials may be saved and manufacturing cost may be reduced, thereby ensuring the sealing and waterproof effects. In addition, at least two mutually spaced waterproof ribs are provided on the connecting end surface of the protrusion body, and each of the waterproof ribs is inclined outwardly relative to the end surface of the protrusion body, so that when the waterproof ribs are squeezed, the waterproof ribs may be further inclined outwardly. When the squeezing force is relatively large, the protrusion body may also be squeezed. Since the waterproof ribs are squeezed to be further inclined in a direction away from each other, it may ensure that the entire waterproof protrusion is squeezed smoothly, so that the protrusion body will not be bent, namely, the waterproof protrusion will not be wrinkled, so that there will not be a gap between the display module and the cabinet, and the sealing and waterproof effects of the waterproof assembly will not be affected.

In one embodiment, a waterproof substrate <NUM>, including: two mounting surfaces <NUM> disposed in the same direction; and a waterproof protrusion <NUM> provided on at least one of the two mounting surfaces <NUM> and including: a protrusion body <NUM> connected with the mounting surface <NUM>, and one end of the protrusion body <NUM> away from the waterproof substrate <NUM> includes a connecting end surface <NUM>; and at least two waterproof ribs <NUM>, and each of the waterproof ribs <NUM> is provided on the connecting end surface <NUM> respectively and is gradually inclined outwardly in a direction away from the connecting end surface <NUM> respectively.

As shown in <FIG>, according to an embodiment, a waterproof assembly <NUM> includes a waterproof substrate <NUM>, which includes two mounting surfaces <NUM> disposed in the same direction. Waterproof protrusions <NUM> are provided on at least one mounting surface <NUM> of the waterproof substrate <NUM>. The waterproof protrusion includes a protrusion body <NUM> and at least two waterproof ribs <NUM>. The protrusion body <NUM> is connected with the mounting surface <NUM>. One end of the protrusion body <NUM> away from the waterproof substrate <NUM> includes a connecting end surface <NUM>, and each waterproof rib <NUM> is provided on the connecting end surface <NUM> respectively and is gradually inclined outwardly in a direction away from the connecting end surface <NUM> respectively, namely, a distance between the two waterproof ribs <NUM> gradually increases in the direction away from the connecting end surface <NUM>. In this embodiment, a size of the protrusion body <NUM> is smaller than a size of the waterproof substrate <NUM>. In this embodiment, a size of the waterproof rib <NUM> is smaller than the size of the protrusion body <NUM>. In one embodiment, a cross-sectional size of the waterproof rib <NUM> is smaller than a cross-sectional size of the protrusion body <NUM>. In this embodiment, the waterproof substrate <NUM>, the protrusion body <NUM> and the waterproof rib <NUM> all have a certain elasticity.

The above-mentioned waterproof assembly <NUM> is configured to be provided between the cabinet of the display screen and the display module of the display screen. The waterproof protrusion <NUM> is easily deformed relative to the waterproof substrate <NUM> having larger size. When the deformation is large, the waterproof effect is better, so that sealing and waterproof effects may be achieved by squeezing the waterproof protrusion <NUM> and the display module, or squeezing the waterproof protrusion <NUM> and cabinet, instead of squeezing the waterproof substrate <NUM> having larger size and the display module, or squeezing the waterproof substrate <NUM> having larger size and the cabinet. So, there is no need to use a waterproof rubber ring with thickness similar to the waterproof substrate <NUM> or even larger than the waterproof substrate <NUM> as a waterproof assembly <NUM>. As a result, the reverse thrust of the waterproof assembly <NUM> on the cabinet or the display module is reduced, which facilitates tightly compressing the cabinet and the display module, and ensures the stability of the connection between the cabinet and the display module. Especially when the cabinet and the display module are connected by means of magnetic attraction, the reverse thrust of the waterproof protrusion <NUM> on the cabinet or the display module is very small, which will not damage the magnetic attraction between the cabinet and the display module. Since it can be sealed and waterproofed only by the waterproof protrusion <NUM>, the thickness of the waterproof substrate <NUM> may be made relatively small, and there is no need to worry about the problem of poor waterproof effect due to a gap existed at the compression portion because of the insufficient thickness of the waterproof rubber ring. As a result, materials may be saved and manufacturing cost may be reduced, thereby ensuring the waterproof effect. In addition, at least two mutually spaced waterproof ribs <NUM> are provided on the connecting end surface <NUM> of the protrusion body <NUM>, and each of the waterproof ribs <NUM> is inclined outwardly relative to the end surface of the protrusion body <NUM>, so that when the waterproof ribs <NUM> are squeezed, the waterproof ribs <NUM> may be further inclined outwardly. When the squeezing force is relatively large, the protrusion body <NUM> may also be squeezed. Since the waterproof ribs <NUM> are squeezed to be further inclined in a direction away from each other, it may ensure that the entire waterproof protrusion <NUM> is squeezed smoothly, so that the protrusion body <NUM> will not be bent, namely, the waterproof protrusion <NUM> will not be wrinkled, so that there will not be a gap between the display module and the cabinet, and the sealing and waterproof effects of the waterproof assembly <NUM> will not be affected.

In order to further improve the waterproof effect of the waterproof assembly <NUM>, in one embodiment, a number of the waterproof protrusions <NUM> is at least two. In this embodiment, at least two waterproof protrusions <NUM> are provided on a mounting surface of the waterproof substrate <NUM>. When a plurality of waterproof protrusions <NUM> are located at one side of the waterproof substrate <NUM>, a multi-layer waterproof effect may be achieved, thereby improving the waterproof effect of the waterproof assembly <NUM>. When the waterproof protrusions <NUM> are provided on both sides of the waterproof substrate <NUM>, both sides of the waterproof substrate <NUM> may be sealed and waterproofed by squeezing the waterproof protrusions <NUM> with the external structure, and the thickness of the waterproof substrate <NUM> may be reduced, and the production cost may also be reduced. In one embodiment, at least one waterproof protrusion <NUM> is provided on the two mounting surfaces <NUM> of the waterproof substrate <NUM> respectively, namely, each mounting surface <NUM> is provided with a waterproof protrusion <NUM> respectively, or each mounting surface <NUM> is provided with two waterproof protrusions <NUM> respectively, so that both sides of the waterproof substrate <NUM> may be sealed and waterproofed with the waterproof protrusions <NUM>, which may further improve the waterproof effect of the waterproof assembly <NUM>, and may reduce the thickness of the waterproof substrate <NUM> and reduce production costs.

In order to further ensure that the waterproof protrusion <NUM> is squeezed smoothly, in one embodiment, the waterproof ribs <NUM> are evenly distributed on the connecting end surface <NUM> respectively. In this way, when a plurality of waterproof ribs <NUM> inclined outwardly away from each other are squeezed, the squeezing stability of the entire waterproof protrusion <NUM> may be further improved, namely, it is further ensured that the waterproof protrusion <NUM> is further stably squeezed. Bending of the protrusion body <NUM> may be further avoided, namely, it may further prevent the wrinkle of waterproof substrate <NUM> from affecting the sealing and waterproof effects of waterproof assembly <NUM>.

In one embodiment, as shown in <FIG>, the number of the waterproof ribs <NUM> is two, and the distance between the two waterproof ribs <NUM> gradually increases in a direction away from the connecting end surface <NUM>, namely, the two waterproof ribs <NUM> are inclined outwardly in a direction away from the connecting end surface <NUM>, or the two waterproof ribs <NUM> are inclined in the same direction in a direction away from the connecting end surface <NUM>. In this embodiment, two waterproof ribs <NUM> are provided on the connecting end surface <NUM> of each protruding body <NUM>, and the two waterproof ribs <NUM> are inclined outwardly, so that a Y-shaped structure is formed between the two waterproof ribs <NUM> and the protrusion body <NUM>, namely, the cross-section of each waterproof rib <NUM> and the cross-section of the protrusion body <NUM> are Y-shaped. In this way, the two waterproof ribs <NUM> may be inclined further away from each other when being squeezed, which not only ensures the sealing effect of squeezing, but also prevents the protrusion body <NUM> from being bent due to uneven force.

In one embodiment, the two waterproof ribs <NUM> are symmetrically arranged, so that the waterproof protrusion <NUM> are more smoothly squeezed. In one embodiment, the waterproof protrusion <NUM> is a Y-shaped structure.

In order to make the waterproof protrusion <NUM> prevent the opening of the external structure from water, in one embodiment, as shown in <FIG> and <FIG>, the protrusion body <NUM> and the waterproof rib <NUM> are both ring-shaped structures. The two ring-shaped waterproof ribs <NUM> are respectively disposed on the ring-shaped protrusion body <NUM>. In this embodiment, the extending direction of the waterproof ribs <NUM> and the extending direction of the protrusion body <NUM> are the same. In this way, the ring-shaped protrusion body <NUM>, the ring-shaped waterproof ribs <NUM> and the waterproof substrate <NUM> together may form a semi-sealed space. When the waterproof ribs <NUM> are squeezed by the external structure, a closed space may be formed, which may prevent water from entering the closed space. If the external structure has an opening, the waterproof protrusion <NUM> may surround the opening, which may prevent the opening from water. For example, when the waterproof ribs <NUM> are squeezed with the display module, the entire waterproof protrusion <NUM> may surround the data interface of the display module, which may prevent the data interface of the display module from water. In one embodiment, the waterproof substrate <NUM> is a ring-shaped structure. A communication opening is defined in the middle of the waterproof substrate <NUM>, and the protrusion body <NUM> and the waterproof ribs <NUM> are arranged around the communication opening, so that when the communication opening is communicated with the data interface of the display module, the waterproof protrusion <NUM> may prevent the data interface of the display module from water when it is squeezed with the display module.

In one embodiment, a plurality of the waterproof protrusions <NUM> extending in a same direction are provided on the same mounting surface <NUM> of the waterproof substrate <NUM>, and the plurality of the waterproof protrusions <NUM> are arranged in ring shapes from inside to outside. In this way, the opening may be prevent from water by the waterproof protrusions <NUM> from the inside to the outside, and the waterproof effect is better.

In one embodiment, the waterproof rib <NUM>, the waterproof protrusion <NUM>, and the waterproof substrate <NUM> are integrally formed, so that the overall structure of the waterproof assembly <NUM> is compact and firm. In this way, the waterproof effect of the waterproof assembly <NUM> is further improved, and the service life of the waterproof assembly <NUM> is also improved.

In one embodiment, as shown in <FIG>, the waterproof assembly <NUM> further includes at least one waterproof protrusion strip <NUM>, which is provided on at least one mounting surface <NUM> of the waterproof substrate <NUM> and is spaced apart from the protrusion body <NUM>. In one embodiment, the waterproof protrusion strip <NUM> extends in the same direction as the protrusion body <NUM>. In one embodiment, the waterproof protrusion strip <NUM> is a ring-shape structure. The waterproof protrusion strip <NUM> cooperates with the waterproof protrusion <NUM> to form multiple waterproof defense lines, which further improves the waterproof effect of the waterproof assembly <NUM>, and there is no need to arrange the waterproof rib <NUM> like the waterproof protrusion <NUM>, thereby reducing the manufacturing difficulty.

As shown in <FIG>, the present application further provides a display screen <NUM>, including a cabinet <NUM> and a display module <NUM> connected with the cabinet <NUM>, and an installation space is defined between the display module <NUM> and the cabinet <NUM>. The display screen <NUM> further includes the waterproof assembly <NUM> according to any one of the above embodiments. The waterproof assembly <NUM> is disposed in the installation space. At least one mounting surface <NUM> of the mounting surface <NUM> of the waterproof substrate <NUM> facing the cabinet <NUM> and the mounting surface <NUM> of the waterproof substrate <NUM> facing the display module <NUM> includes the waterproof protrusion <NUM>. At least one of the cabinet <NUM> and the display module <NUM> is abutted against the waterproof ribs <NUM>. In this embodiment, at least one of the cabinet <NUM> and the display module <NUM> is connected to the waterproof ribs <NUM> by squeezing.

The waterproof assembly <NUM> is provided between the cabinet <NUM> of the display screen <NUM> and the display module <NUM> of the display screen <NUM>. The waterproof protrusion <NUM> is easily deformed relative to the waterproof substrate <NUM> having larger size. When the deformation is large, the waterproof effect is better, so that sealing and waterproof effects may be achieved by squeezing the waterproof protrusion <NUM> and the display module <NUM>, or squeezing the waterproof protrusion <NUM> and cabinet <NUM>, instead of squeezing the waterproof substrate <NUM> having larger size and the display module <NUM>, or squeezing the waterproof substrate <NUM> having larger size and the cabinet <NUM>. So, there is no need to use a waterproof rubber ring with thickness similar to the waterproof substrate <NUM> or even larger than the waterproof substrate <NUM> as a waterproof assembly <NUM>. As a result, the reverse thrust of the waterproof assembly <NUM> on the cabinet <NUM> or the display module <NUM> is reduced, which facilitates tightly squeezing the cabinet <NUM> and the display module <NUM>, and ensures the stability of the connection between the cabinet <NUM> and the display module <NUM>. Especially when the cabinet <NUM> and the display module <NUM> are connected by means of magnetic attraction, the reverse thrust of the waterproof protrusion <NUM> on the cabinet <NUM> or the display module <NUM> is very small, which will not damage the magnetic attraction between the cabinet <NUM> and the display module <NUM>. Since it can be sealed and waterproofed only by the waterproof protrusion <NUM>, the thickness of the waterproof substrate <NUM> may be made relatively small, and there is no need to worry about the problem of poor waterproof effect due to a gap existed at the compression portion because of the insufficient thickness of the waterproof rubber ring. As a result, materials may be saved and manufacturing cost may be reduced, thereby ensuring the waterproof effect. In addition, at least two mutually spaced waterproof ribs <NUM> are provided on the connecting end surface <NUM> of the protrusion body <NUM>, and each of the waterproof ribs <NUM> is inclined outwardly relative to the end surface of the protrusion body <NUM>, so that when the waterproof ribs <NUM> are squeezed, the waterproof ribs <NUM> may be further inclined outwardly. When the squeezing force is relatively large, the protrusion body <NUM> may also be squeezed. Since the waterproof ribs <NUM> are squeezed to be further inclined in a direction away from each other, it may ensure that the entire waterproof protrusion <NUM> is squeezed smoothly, so that the protrusion body <NUM> will not be bent, namely, the waterproof protrusion <NUM> will not be wrinkled, so that there will not be a gap between the display module <NUM> and the cabinet <NUM>, and the sealing and waterproof effects of the waterproof assembly <NUM> will not be affected.

In one embodiment, as shown in <FIG>, <FIG>, the mounting surface <NUM> of the waterproof substrate <NUM> facing the display module <NUM> includes the waterproof protrusion <NUM>. The display module <NUM> is abutted against the waterproof ribs <NUM>. The mounting surface <NUM> of the waterproof substrate <NUM> facing away from the waterproof protrusion <NUM> is abutted against the cabinet <NUM>. In this embodiment, the display module <NUM> is connected with the waterproof ribs <NUM> by squeezing, and the mounting surface <NUM> of the waterproof substrate <NUM> facing away from the waterproof protrusion <NUM> is connected with the cabinet <NUM> by squeezing. The squeezing force between the cabinet <NUM> and the waterproof substrate <NUM> is substantially equal to the squeezing force between the waterproof ribs <NUM> and the display module <NUM>. The squeezing force required for the waterproof ribs <NUM> to deform to achieve sealing and waterproof effects do not need to be too large, so the squeezing force between the cabinet <NUM> and the waterproof substrate <NUM> is not large. Therefore, the waterproof substrate <NUM> will not deform greatly even if the waterproof substrate <NUM> is elastic. As a result, the reverse thrust of the waterproof substrate <NUM> is small and will not overcome the magnetic attraction between the cabinet <NUM> and the display module <NUM>, so that the cabinet <NUM> may not be pushed away and be separated from the display module <NUM>. Therefore, the waterproof ribs <NUM> of the waterproof protrusion <NUM> may be used to achieve good sealing and waterproof effects without affecting the stability of the connection between the cabinet <NUM> and the display module <NUM>.

In one embodiment, the mounting surface <NUM> of the waterproof substrate <NUM> facing the cabinet <NUM> includes the waterproof protrusion <NUM>. The cabinet <NUM> is abutted against the waterproof ribs <NUM>. The mounting surface <NUM> of the waterproof substrate <NUM> facing away from the waterproof protrusion <NUM> is abutted against the display module <NUM>. In this embodiment, the cabinet <NUM> is abutted against the waterproof ribs <NUM>. The mounting surface <NUM> of the waterproof substrate <NUM> facing away from the waterproof protrusion <NUM> is abutted against the display module <NUM> by squeezing. The squeezing force between the display module <NUM> and the waterproof substrate <NUM> is substantially equal to the squeezing force between the waterproof ribs <NUM> and the cabinet <NUM>. The squeezing force required for the waterproof ribs <NUM> to deform to achieve sealing and waterproof effects do not need to be too large, so the squeezing force between the display module <NUM> and the waterproof substrate <NUM> is not large. Therefore, the waterproof substrate <NUM> will not deform greatly even if the waterproof substrate <NUM> is elastic. As a result, the reverse thrust of the waterproof substrate <NUM> is small and will not overcome the magnetic attraction between the cabinet <NUM> and the display module <NUM>, so that the display module <NUM> may not be pushed away and be separated from the cabinet <NUM>. Therefore, the waterproof ribs <NUM> of the waterproof protrusion <NUM> may be used to achieve good sealing and waterproof effects without affecting the stability of the connection between the cabinet <NUM> and the display module <NUM>.

In one embodiment, the mounting surface <NUM> of the waterproof substrate <NUM> facing the cabinet <NUM> and the mounting surface <NUM> of the waterproof substrate <NUM> facing the display module <NUM> are respectively provided with the waterproof protrusion <NUM>. The waterproof ribs <NUM> provided on one mounting surface <NUM> of the waterproof substrate <NUM> is abutted against the display module <NUM>, and the waterproof ribs <NUM> provided on the other mounting surface <NUM> of the waterproof substrate <NUM> is abutted against the cabinet <NUM>. In this embodiment, The waterproof ribs <NUM> provided on one mounting surface <NUM> of the waterproof substrate <NUM> is connected with the display module <NUM> by squeezing, and the waterproof ribs <NUM> provided on the other mounting surface <NUM> of the waterproof substrate <NUM> is connected with the cabinet <NUM> by squeezing. In this way, better sealing and waterproof effects of both sides of the waterproof substrate <NUM> may be achieved by the waterproof protrusion <NUM> being squeezed with the external structure, thereby further improving the waterproof effect of the waterproof assembly <NUM>, reducing the thickness of the waterproof substrate <NUM>, and reducing the production cost.

In order to facilitate arrangement of the waterproof assembly <NUM>, in one embodiment, at least one of the cabinet <NUM> and the display module <NUM> defines an embedded slot <NUM>, and the waterproof assembly <NUM> is embedded in the embedded slot <NUM>. In this way, it is convenient to arrange the waterproof assembly <NUM>, and the waterproof effect of the waterproof assembly <NUM> may be improved. In one embodiment, as shown in <FIG>, the display module <NUM> defines at least one embedded slot <NUM>, and the waterproof substrate <NUM> is provided with at least one waterproof protrusion <NUM> on a side facing the display module <NUM>. Each waterproof protrusion <NUM> is embedded in an embedded slot <NUM> respectively and abutted against the bottom of the embedded slot <NUM>. In this embodiment, each waterproof protrusion <NUM> is embedded in an embedded slot <NUM> respectively and is connected with the bottom of the embedded slot <NUM> by squeezing. In this way, the waterproof assembly <NUM> may be easily arranged, and the sealing and waterproof effects may be achieved by connecting the waterproof protrusion <NUM> and the bottom of the embedded slot <NUM> by squeezing.

In one embodiment, the waterproof substrate <NUM> is a ring-shaped structure. The display module <NUM> includes a data interface, and the waterproof substrate <NUM> surrounds the data interface.

In one embodiment, as shown in <FIG> and <FIG>, the mounting surface <NUM> of the waterproof substrate <NUM> facing the cabinet <NUM> and the mounting surface <NUM> of the waterproof substrate <NUM> facing the display module <NUM> are provided with the waterproof protrusion <NUM> respectively. The display module <NUM> is abutted against the waterproof protrusion <NUM> provided on one mounting surface <NUM> of the waterproof substrate <NUM>, and the cabinet <NUM> is abutted against the waterproof protrusion <NUM> provided on the other mounting surface <NUM> of the waterproof substrate <NUM>. A surface of the cabinet <NUM> in contact with the at least one waterproof protrusion <NUM> is defined as a first abutting surface <NUM>, and a surface of the display module <NUM> in contact with the at least one waterproof protrusion <NUM> is defined as a second abutting surface <NUM>. Namely, the cabinet <NUM> has the first abutting surface <NUM> abutted against the waterproof protrusion <NUM>, and the display module <NUM> has the second abutting surface <NUM> abutted against the waterproof protrusion <NUM>. At least one of the first abutting surface <NUM> and the second abutting surface <NUM> is inclined with respect to the mounting surface <NUM>. In one embodiment, the first abutting surface <NUM> and the second abutting surface <NUM> are inclined with respect to the mounting surface <NUM> respectively. In this way, the end of the waterproof protrusion <NUM> away from the waterproof substrate <NUM> and the first abutting surface <NUM> are not vertically abutted. A better waterproof effect may be achieved when the squeezing force between the waterproof protrusion <NUM> and the first abutting surface <NUM> reaches a preset force. When the force between the waterproof protrusion <NUM> and the inclined first abutting surface <NUM> is a preset force, it is assumed that the waterproof protrusion <NUM> is disposed away from the waterproof substrate <NUM> in the horizontal direction, and the mounting surface <NUM> is set vertically. The preset force may be decomposed into a first component force in the horizontal direction and a second component force in the vertical direction. Since the first component force is smaller than the preset force, the squeezing force of the waterproof protrusion <NUM> on the cabinet <NUM>, namely, the first component force becomes smaller. If the first abutting surface <NUM> is parallel to the mounting surface <NUM>, rather than being inclined with respect to the mounting surface <NUM>, the squeezing force of the waterproof protrusion <NUM> on the cabinet <NUM> in the horizontal direction, namely, the first component force may be equal to the preset force. But if the first abutting surface <NUM> is set as an inclined surface with respect to the mounting surface <NUM>, the squeezing force of the waterproof protrusion <NUM> on the cabinet <NUM> in the horizontal direction, namely, the first component force may be smaller to the preset force. Similarly, the abutment of the second abutting surface <NUM> of the display module <NUM> and the waterproof protrusion <NUM> is similar to the abutment of the first abutting surface <NUM> and the waterproof protrusion <NUM>. Therefore, when the first abutting surface <NUM> and the second abutting surface <NUM> are inclined relative to the mounting surface <NUM> respectively, the squeezing force between the waterproof protrusion <NUM> and the cabinet <NUM> and the squeezing force between the waterproof protrusion <NUM> and the display module <NUM> become smaller. However, since the squeezing force between the waterproof protrusion <NUM> and the first abutting surface <NUM> and the squeezing force between the waterproof protrusion <NUM> and the second abutting surface <NUM> remain unchanged, the sealing and waterproof effects of the waterproof protrusion <NUM> on the display screen <NUM> may still be guaranteed. In one embodiment, the number of the first abutting surface <NUM> and the number of the second abutting surface <NUM> are multiple, and the number of the waterproof protrusion <NUM> is multiple. Each first abutting surface <NUM> is abutted against at least one waterproof protrusion <NUM>, and each second abutting surface <NUM> is abutted against at least one waterproof protrusion <NUM>. In this way, multi-layered sealing and waterproof effects may be achieved, and the squeezing force of each position where the waterproof assembly <NUM> being abutted against the display module <NUM> or the cabinet <NUM> is small, and the sealing and waterproof effects of the waterproof protrusion <NUM> on the display screen <NUM> may still be guaranteed.

In one embodiment, the display module <NUM> is abutted against the waterproof ribs <NUM> provided on one mounting surface <NUM> of the waterproof substrate <NUM>, and the cabinet <NUM> is abutted against the waterproof ribs <NUM> provided on the other mounting surface <NUM> of the waterproof substrate <NUM>. A surface of the cabinet <NUM> in contact with the waterproof ribs <NUM> is defined as a first abutting surface <NUM>. A surface of the display module <NUM> in contact with the waterproof ribs <NUM> is defined as a second abutting surface <NUM>. At least one of the first abutting surface <NUM> and the second abutting surface <NUM> is inclined with respect to the connecting end surface <NUM>.

The technical features of the embodiments described above can be arbitrarily combined. In order to simplify the description, all possible combinations of the technical features in the above embodiments have not been described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
