The orientation or the positional relationship "lateral" is based on the orientation or positional relationship shown in <FIG>. The "height" refers to a direction from top to bottom in <FIG>. It should be understood that these orientation terms are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or the component must have a specific orientation, or be configured in a specific orientation and operated, and should not be understood as a limitation to the present disclosure.

An embodiment of the present disclosure provides a compressor anticollision structure for in an electrical device. As shown in <FIG> and <FIG>, the compressor anticollision structure includes a support assembly <NUM>, a compressor assembly <NUM>, and an anticollision strip <NUM>. The support assembly <NUM> includes a chassis <NUM>. The compressor assembly <NUM> is provided at the chassis <NUM> and includes a compressor <NUM>. The anticollision strip <NUM> is connected to the support assembly <NUM>, and a head end of the anticollision strip <NUM> is connected to a tail end of the anticollision strip <NUM> to surround a periphery of the compressor <NUM>. Or, two opposite ends in a length direction of the anticollision strip <NUM> are respectively connected to the support assembly <NUM>, and the compressor <NUM> is located in an area enclosed by the anticollision strip <NUM> and the support assembly <NUM>.

In some embodiments, a head end of the anticollision strip <NUM> is connected to a tail end of the anticollision strip <NUM> to form an annular structure. The anticollision strip <NUM> in the annular structure surrounds the periphery of the compressor <NUM>. When the electrical device shakes violently or falls down and causes the compressor <NUM> to shake violently, the anticollision strip <NUM> can prevent the compressor <NUM> from hitting the external components and/or other internal components of the electrical device. In other embodiments, two opposite ends in a length direction of the anticollision strip <NUM> are respectively connected to the support assembly <NUM>, to enclose an area in which the compressor <NUM> can be protected. The compressor <NUM> is located in the area, and when the compressor <NUM> shakes violently, the peripheral anticollision strip <NUM> of the compressor <NUM> or the support assembly <NUM> can prevent the compressor <NUM> from hitting the external components and/or other internal components of the electrical device.

Another embodiment of the present disclosure provides an electrical device, including the compressor anticollision structure in any embodiment of the present disclosure.

The electrical device, which has a compressor <NUM>, may be a dehumidifier, an air conditioner outdoor unit, or a refrigerator, and the like.

The anticollision strip <NUM> is connected to the support assembly <NUM>, which can prevent the compressor <NUM> from hitting the external components and/or other internal components of the electrical device when the compressor <NUM> shakes violently. In this case, the probability of the compressor <NUM> hitting the external components and/or other internal components of the electrical device can be greatly reduced, which can improve the product quality of the electrical device.

The anticollision strip <NUM> can be connected to the support assembly <NUM> in many ways. For example, as shown in <FIG> and <FIG>, two opposite ends in a length direction of the anticollision strip <NUM> are respectively connected to the support assembly <NUM>. In an embodiment, the support assembly <NUM> includes a middle partition <NUM> provided at the chassis <NUM>, and two opposite ends in a length direction of the anticollision strip <NUM> are respectively connected to the middle partition <NUM>. The middle partition <NUM> is mainly used for separating the compressor <NUM> from part internal components of the electrical device. For example, the middle partition <NUM> separates the compressor <NUM> from the air flue, the water tank and other components. That is to say, the middle partition <NUM> can prevent the compressor <NUM> from hitting the internal components on the side of the middle partition <NUM> away from the compressor <NUM>. Two opposite ends in a length direction of the anticollision strip <NUM> are respectively connected to the middle partition <NUM>. In this way, a ring of protective structure may be formed in the periphery of the compressor <NUM>, which may prevent the compressor <NUM> from hitting the nearby external components or internal components.

It can be understood that in other embodiments, two opposite ends in a length direction of the anticollision strip <NUM> may not be connected to the middle partition <NUM>. The support assembly <NUM> can further include the support plate, the support pillar, and other structures provided at the chassis <NUM>. Two opposite ends in the length direction of the anticollision strip <NUM> may be connected to the support plate or the support pillar.

For the connection method that a head end of the anticollision strip <NUM> is connected to a tail end of the anticollision strip <NUM>, the anticollision strip <NUM> may be connected to the middle partition <NUM>, the support plate or the support pillar. In this case, the middle partition <NUM>, the support plate or the support pillar are only used for fixing the anticollision strip <NUM>, but not for enclosing an area with the anticollision strip <NUM> to hold the compressor <NUM>.

In an embodiment, as shown in <FIG>, the anticollision strip <NUM> includes a strip-shaped force-bearing body <NUM>. The anticollision strip <NUM> is connected to the support assembly <NUM> through the strip-shaped force-bearing body <NUM>. That is, two opposite ends in a length direction of the strip-shaped force-bearing body <NUM> may be connected to the middle partition <NUM>, the support plate or the support pillar, to enclose an area for holding the compressor <NUM>.

The strip-shaped force-bearing body <NUM> may be components such as a sheet metal component with certain strength and rigidity. As a main force structure of the anticollision strip <NUM>, when the compressor <NUM> shakes violently and hits the anticollision strip <NUM>, the strip-shaped force-bearing body <NUM> may bear the impact from the compressor <NUM>.

In some embodiments, the anticollision strip <NUM> further includes a first flexible protection strip <NUM> provided at a side of the strip-shaped force-bearing body <NUM> away from the compressor <NUM>. The first flexible protection strip <NUM> can be made of the polyethylene (PE) sponge, the rubber foam sponge, the silicone, and the like. In some cases, when hitting the external components or other internal components of the electrical device, the anticollision strip <NUM> is contacted to the external components or other internal components through the first flexible protection strip <NUM>, which can play a cushion and protection role in preventing the external components or other internal components from damage.

In an embodiment, as shown in <FIG>, the anticollision strip <NUM> can also include a second flexible protection strip <NUM> provided at a side of the strip-shaped force-bearing body <NUM> facing the compressor <NUM>. The second flexible protection strip <NUM> can be made of the PE sponge, the rubber foam sponge, the silicone, and the like. The second flexible protection strip <NUM> can prevent the strip-shaped force-bearing body <NUM> from hitting the compressor <NUM> to cause damage to the compressor <NUM>.

It can be understood that in an embodiment, a head end of the anticollision strip <NUM> is connected to a tail end of the anticollision strip <NUM> to surround a periphery of the compressor <NUM>. The first flexible protection strip <NUM> is provided at a side of the strip-shaped force-bearing body <NUM> away from the compressor <NUM>, and/or, the second flexible protection strip <NUM> is provided at a side of the strip-shaped force-bearing body <NUM> facing the compressor <NUM>.

As shown in <FIG> and <FIG>, in an embodiment, two opposite ends in a length direction of the strip-shaped force-bearing body <NUM> are respectively connected to the middle partition <NUM>. The anticollision strip <NUM> further includes at least two first positioning members <NUM>, and each of the two opposite ends in the length direction of the strip-shaped force-bearing body <NUM> is provided with at least one of the two first positioning members <NUM>. The support assembly <NUM> further includes at least two second positioning members <NUM> provided at the middle partition <NUM>. One of the first positioning member <NUM> and the second positioning member <NUM> is a positioning hole, and another of the first positioning member <NUM> and the second positioning member <NUM> is a positioning pillar. A positioning pillar is inserted in a corresponding positioning hole.

A fastener can be used for connecting each of the two opposite ends in a length direction of the strip-shaped force-bearing body <NUM> with the middle partition <NUM>. For example, a screw can be used for fixing the middle partition <NUM> on each of the two opposite ends, and the positioning pillar can be plugged in a corresponding positioning hole before installing the screws. In this way, the first fastening connection hole 31a on the strip-shaped force-bearing body <NUM> can be aligned with the second fastening connection hole 12a on the middle partition <NUM>, thereby improving the assembly efficiency of the anticollision strip <NUM>.

In an embodiment, as shown in <FIG> and <FIG>, the middle partition <NUM> includes a plate body <NUM> and at least one enhanced boss <NUM> protruding from a side of the plate body <NUM> away from the compressor <NUM>. That is, the number of the enhanced boss <NUM> may be one or more. The plate body <NUM> is provided at the chassis <NUM>, and the enhanced boss <NUM> extends along a height direction of the plate body <NUM>. The enhanced boss <NUM> may increase structural strength and rigidity of the middle partition <NUM>, thereby preventing the compressor <NUM> from hitting and damaging the middle partition <NUM> during the shaking process of the compressor <NUM>.

In addition, the size of the enhanced boss <NUM> in an embodiment of the present disclosure is relatively large. Therefore, a groove matching the shape of the enhanced boss <NUM> can be directly milled on the mold of the middle partition <NUM> during production. In this way, the mold processing method is simple and convenient, and the manufacturing cost of the mold can be saved, thereby reducing the production cost of the electrical device.

In an embodiment, as shown in <FIG>, along a height direction of the middle partition <NUM>, the middle partition <NUM> includes a first portion 121a and a second portion 121b. The second portion 121b is provided at a top side of the first portion 121a. A continuous stepped surface 121c is formed in a junction between a side of the first portion 121a away from the compressor <NUM> and a side of the second portion 121a away from the compressor <NUM>, and the continuous stepped surface 121c extends along a lateral direction of the middle partition <NUM> and departs from the chassis <NUM>. A part of the enhanced boss <NUM> is provided at the first portion 121a of the middle partition <NUM>, and another part of the enhanced boss <NUM> is provided at the second portion 121b of the middle partition <NUM>. That is, each enhanced boss <NUM> is divided into two sub-bosses. In order to facilitate description, the sub-boss close to the chassis <NUM> is the first sub-boss <NUM>, and the sub-boss provided at the top side of the first sub-boss <NUM> is the second sub-boss <NUM>. A part of the continuous stepped surface 121c is located on the plate body <NUM>, and another part of the continuous stepped surface 121c is located at a junction between the first sub-boss <NUM> and the second sub-boss <NUM>. An outer wall of the second sub-boss <NUM> away from the plate body <NUM> can be an inclined plane, to facilitate to arrange structures such as the air flue on the side of the second sub-boss <NUM> away from the plate body <NUM>. In this way, not only the structural rigidity of the middle partition <NUM> can be further improved, but also the internal structure of the electrical device can be more compact.

The number of the enhanced bosses <NUM> is not limited, which can be one or more. In an embodiment, the number of the enhanced bosses <NUM> may be multiple, and multiple enhanced bosses <NUM> are distributed at intervals along a lateral direction of the plate body <NUM>. In this case, the structural strength and rigidity of the middle partition <NUM> can be further improved.

In an embodiment, as shown in <FIG> and <FIG>, the compressor assembly <NUM> further includes a support plate <NUM> at a bottom of the compressor <NUM>, and the compressor anticollision structure includes a fixation assembly <NUM>. The number of the support plates <NUM> may be one or more. The number of the fixation assemblies <NUM> is the same as the number of the support plates <NUM>. The fixation assembly <NUM> includes a support pillar <NUM> and a cushion pad <NUM>, and a bottom of the support pillar <NUM> is connected to the chassis <NUM>. The cushion pad <NUM> is sleeved outside the support pillar <NUM>. The support plate <NUM> is sleeved outside the cushion pad <NUM> and is spaced apart from the support pillar <NUM>. A top of the cushion pad <NUM> has a free movement stroke along an axial direction of the cushion pad <NUM>. When compressed <NUM> shakes, the top of the cushion pad <NUM> may move along the axial direction of the cushion pad <NUM>. Driven by the cushion pad <NUM>, the support plate <NUM> on the cushion pad <NUM> may move together with the cushion pad <NUM>, so that the cushion pad <NUM> can play a cushion role for the compressor <NUM>.

There are many ways to make the top of the cushion pad <NUM> have a free movement stroke. In an embodiment, as shown in <FIG>, a bottom of the cushion pad <NUM> is engaged with the support pillar <NUM> by an interference fit, and a top of the cushion pad <NUM> is engaged with the support pillar <NUM> by a loose fit. That is, the bottom of the cushion pad <NUM> is fastened to the support pillar <NUM>. When the compressor <NUM> shakes, the top of the cushion pad <NUM> can move along the axial direction of the cushion pad <NUM> on the support pillar <NUM>, and the bottom of the cushion pad <NUM> cannot move. In some embodiments, the bottom of the cushion pad <NUM> may be fastened to the chassis <NUM>, and the top of the cushion pad <NUM> may be engaged with the support pillar <NUM> in a loose fit, as long as the top of the cushion pad <NUM> has a free movement stroke along an axial direction of the cushion pad <NUM>.

In an embodiment, as shown in <FIG>, the fixation assembly <NUM> may further include a gasket <NUM> and a nut <NUM> threadedly connected to the support pillar <NUM>. The cushion pad <NUM> is located between the chassis <NUM> and the gasket <NUM>, and an abutment surface 41a is formed at the support pillar <NUM>. The nut <NUM> abuts the gasket <NUM> on the abutment surface 41a. Along an axial direction of the support pillar <NUM>, the gasket <NUM> is spaced apart from the cushion pad <NUM> and the support plate <NUM>, to make the top of the cushion pad <NUM> have the free movement stroke along the axial direction of the cushion pad <NUM>.

In some cases, such as the electrical device shakes violently or falls down during transportation and the compressor <NUM> shakes violently, the cushion pad <NUM> will move along an axial direction of the cushion pad <NUM> in a large range. When the top of the cushion pad <NUM> moves to the limiting position along the axial direction close to the gasket <NUM>, the cushion pad <NUM> abuts against the gasket <NUM>. That is, the gasket <NUM> can limit the cushion pad <NUM>, to limit the top of the cushion pad <NUM> within a certain range.

In an embodiment, as shown in <FIG>, a minimum distance H1 between the cushion pad <NUM> and the gasket <NUM> is <NUM> to <NUM> along an axial direction of the support pillar <NUM>. Within this distance range, the cushion pad <NUM> may play a better cushion and damping role, and it can be avoided that the movement range of the top of the cushion pad <NUM> along the axial direction becomes too large to make the shaking range of the compressor <NUM> increased.

In an embodiment, as shown in <FIG>, the nut <NUM> and the gasket <NUM> form an integrated structure. That is, the nut <NUM> and the gasket <NUM> are integrated together. In this way, not only the assembly efficiency can be improved, but also the nut <NUM> and the gasket <NUM> can be prevented from rubbing against each other to produce an abnormal noise when the electrical device is operating.

As shown in <FIG>, the gasket <NUM> may be shaped in a circle, a rectangular, a polygon, or an anomalous shape, which will not be limited here.

The specific structure of the gasket <NUM> is not limited. For example, the gasket <NUM> may be shaped in a plate, a curved plate, and the like.

In other embodiments, the nut <NUM> and the gasket <NUM> may be separated structures fastened to each other. For example, the nut <NUM> and the gasket <NUM> can be connected together by welding.

In an embodiment, as shown in <FIG>, a folded edge 432a folding towards the chassis <NUM> is formed at the gasket <NUM>, and an accommodation space 432b is enclosed by the folded edge 432a. An end of the cushion pad <NUM> away from the chassis <NUM> extends into the accommodation space 432b, and the folded edge 432a is configured to face the support plate <NUM>. When the electrical device shakes violently or falls down, the folded edge 432a can press the support plate <NUM>, to avoid a too large shaking range of the compressor <NUM>. In this way, the possibility of the compressor <NUM> hitting the external components and/or other internal components can be further reduced.

In an embodiment, as shown in <FIG>, a distance H2 between a bottom surface of the folded edge 432a and a top surface of the support plate <NUM> is <NUM> to <NUM>. Within this distance range, a normal shaking range of the compressor <NUM> can be ensured to play a better cushion and damping role, and the compressor <NUM> can be better protected under the abnormal shaking condition.

In an embodiment, as shown in <FIG>, a stepped hole 11a is formed at the chassis <NUM>. The stepped hole 11a includes an installation sub-hole 11b and a non-circular sub-hole 11c at a bottom side of the installation sub-hole 11b. The compressor assembly <NUM> includes a support plate <NUM> provided at a bottom of the compressor <NUM>. The compressor anticollision structure includes a fixation assembly <NUM>, and the fixation assembly <NUM> includes a bolt member <NUM>', a cushion pad <NUM>, and a lock member <NUM>. The bolt member <NUM>' includes a rod body <NUM> and a position-limiting head <NUM> connected to a bottom of the rod body <NUM>. The rod body <NUM> is connected to the installation sub-hole 11b by an interference fit, and the position-limiting head <NUM> is connected to the non-circular sub-hole 11c by a stopping fit. The cushion pad <NUM> is sleeved outside the rod body <NUM>. The support plate <NUM> is sleeved outside the cushion pad <NUM> and is spaced apart from the bolt member <NUM>'. The lock member <NUM> is connected to the rod body <NUM> and is provided at a top side of the cushion pad <NUM>.

The cushion pad <NUM> can play a cushion role on the compressor <NUM>, and the lock member <NUM> can limit the cushion pad <NUM>. In this way, when the electrical device shakes violently or falls down, it can be avoided that the movement range of the cushion pad <NUM> along the axial direction becomes too large to make the shaking range of the compressor <NUM> increased.

During the assembly process, when the lock member <NUM> is screwed by the operator, the position-limiting head <NUM> is connected to the non-circular sub-hole 11c by a stopping fit. In this case, the bolt member <NUM>' can be prevented from rotating with the lock member <NUM>, so that the lock member <NUM> can be screwed up. The rod body <NUM> is connected to the installation sub-hole 11b by an interference fit, which can make the bolt member <NUM>' connected to the chassis <NUM> tightly. That is, in the compressor anticollision structure of the embodiments of the present disclosure, the lock member <NUM> can be locked on the bolt member <NUM>', and the bolt member <NUM>' can be connected to the chassis <NUM> tightly. When the electrical device shakes violently or falls down, the bolt member <NUM>' and/or the lock member <NUM> are difficult to be loose. In this case, the compressor <NUM> can be fastened to the chassis <NUM> without a large shaking range, which can greatly reduce the possibility of the compressor <NUM> hitting the external components or other internal components.

In the embodiment of the present disclosure, the number of the support plates <NUM> may be one or more. The number of the fixation assemblies <NUM> can be adjusted according to the number of the support plates <NUM>, as long as each support plate <NUM> can be connected to a corresponding fixation assembly <NUM> respectively.

The non-circular sub-hole 11c on the chassis <NUM> can be shaped in a polygon, a semicircular, an oval, or an anomalous shape, as long as the non-circular sub-hole 11c can prevent the position-limiting head <NUM> from rotating.

In an embodiment, as shown in <FIG>, the rod body <NUM> includes a knurling section 411a, a bare section 411b, and a thread section 411c. The bare section 411b is located between the knurling section 411a and the thread section 411c. The knurling section 411a passes through the installation sub-hole 11b and is connected to the installation sub-hole 11b by the interference fit. The cushion pad <NUM> is sleeved outside the bare section 411b, and the lock member <NUM> is threadedly connected to the thread section 411c.

The knurling section 411a on the bolt member <NUM>' may help increase the contact area and friction between the bolt member <NUM>' and a corresponding side wall of the installation sub-hole 11b, to make the bolt member <NUM>' connected to the chassis <NUM> more tightly. The bare section 411b may reduce the friction between the bolt member <NUM>' and the cushion pad <NUM>, so that the cushion pad <NUM> can play a cushion and damping role on the compressor <NUM> by stretching out and drawing back along the axial direction. In addition, the structure of the bolt member <NUM>' is simple, and easy to process. In this case, not only the reliability of the bolt member <NUM>' can be improved, but also the manufacturing cost of the bolt member <NUM>' can be saved.

The pattern on the knurling section 411a of the bolt member <NUM>' may be straight lines or a mesh, as long as the knurling section 411a can be connected to the installation sub-hole 11b by an interference fit.

In an embodiment, as shown in <FIG>, the stepped hole 11a passes through the chassis <NUM>, and the bolt member <NUM>' passes from a bottom side of the chassis <NUM> into the stepped hole 11a.

In an embodiment of the present disclosure, the chassis <NUM> may be an injection molding component. The bolt member <NUM>' may be assembled on the chassis <NUM> in many ways. For example, when the chassis <NUM> is not completely cooled after injection molding, the bolt member <NUM>' may be pressed from a bottom side of the chassis <NUM> into the stepped hole 11a through a tool. After the chassis <NUM> is completely cooled, due to thermal expansion and contraction of the chassis <NUM>, the knurling section 411a on the bolt member <NUM>' can be connected to the installation sub-hole 11b by the interference fit. For another example, after the chassis <NUM> is completely cooled, the bolt member <NUM>' is heated, and the heated bolt member <NUM>' can be pressed from the bottom side of the chassis <NUM> into the stepped hole 11a through the tool. After the bolt member <NUM>' is completely cooled, the knurling section 411a on the bolt member <NUM>' can be connected to the installation sub-hole 11b by the interference fit. The bolt member <NUM>' can be assembled easily in both above two ways.

In other embodiments, the chassis <NUM> can be injected on the bolt member <NUM>'. The knurling section 411a on the bolt member <NUM>' and the position-limiting head <NUM> can be put in the injection mold of the chassis <NUM> in advance. When the injection molding of the chassis <NUM> is finished, the bolt member <NUM>' is integrated with the chassis <NUM>.

In an embodiment, as shown in <FIG>, the lock member <NUM> is spaced apart from the cushion pad <NUM> along an axial direction of the bolt member <NUM>', to make the cushion pad <NUM> have a free movement stroke along the axial direction of the cushion pad <NUM>.

When the electrical device shakes violently or falls down, the cushion pad <NUM> can move on the bare section 411b of the bolt member <NUM>' along the axial direction of the cushion pad <NUM>. Driven by the cushion pad <NUM>, the support plate <NUM> sleeved outside the cushion pad <NUM> can move with the cushion pad <NUM> together, thereby improving the cushion and damping effect of the cushion pad <NUM>.

In an embodiment, as shown in <FIG> and <FIG>, the lock member <NUM> may include a nut <NUM> and a gasket <NUM>. An abutment surface 41a away from the bare section 411b is formed in a junction between the thread section 411c and the bare section 411b. The nut <NUM> is threadedly connected to the thread section 411c and abuts the gasket <NUM> on the abutment surface 41a. That is, through the gasket <NUM>, the lock member <NUM> may limit the cushion pad <NUM>, thereby limiting the cushion pad <NUM> within a certain movement range.

It can be understood that in some embodiments, the lock member <NUM> can only have a nut <NUM> without the gasket <NUM>, and the nut <NUM> can be spaced apart from the cushion pad <NUM> to limit the cushion pad <NUM> within a certain range.

In other embodiments, the lock member <NUM> may not be spaced apart from the cushion pad <NUM>. For example, the lock member <NUM> can contact to the cushion pad <NUM>, or the lock member <NUM> can abut against the cushion pad <NUM> tightly.

In an embodiment, as shown in <FIG> and <FIG>, the cushion pad <NUM> includes a first axis hole 42a and a second axis hole 42b communicated with each other. The first axis hole 42a is located at a bottom side of the second axis hole 42b, and a hole diameter of the first axis hole 42a is less than a hole diameter of the second axis hole 42b. The bare section 411b passes through the first axis hole 42a and the second axis hole 42b.

The cushion pad <NUM> is generally made of elastic materials, and the specifications of the bolt member <NUM>' may be different according to different models of the electrical device. For example, the bolt member <NUM>' with a diameter of <NUM> on the bare section 411b is required in the electrical device A, and the bolt member <NUM>' with a diameter of <NUM> on the bare section 411b is required in the electrical device B, in this case, the hole diameter of the first axis hole 42a can be about <NUM>, and the second axis hole 42b can be about <NUM>. After the bolt member <NUM>' with a diameter of <NUM> on the bare section 411b passes through the first axis hole 42a and the second axis hole 42b, the first axis hole 42a can be engaged with the bare section 411b. After the bolt member <NUM>' with a diameter of <NUM> on the bare section 411b passes through the first axis hole 42a and the second axis hole 42b, the second axis hole 42b can be engaged with the bare section 411b. In addition, through elastic deformation, the cushion foot pad <NUM> enables the bare section 411b to match with the first axis hole 42a by the interference fit. That is, the first axis hole 42a and the second axis hole 42b with different hole diameters enable the cushion foot pad <NUM> to match with the bolt member <NUM>' with different diameters on the bare section 411b. In this way, the universality of the cushion foot pad <NUM> can be improved.

In an embodiment, as shown in <FIG>, <FIG>, <FIG> and <FIG>, the compressor anticollision structure further includes a surrounding plate <NUM>. The surrounding plate <NUM> protrudes from a top surface of the chassis <NUM> and surrounds the installation sub-hole 11b to enclose a limiting space 50a communicated with the installation sub-hole 11b. A bottom of the cushion pad <NUM> is located in the limiting space 50a. The surrounding plate <NUM> can limit the cushion pad <NUM>, to avoid a too large deviation along the radial direction of the cushion pad <NUM> when the compressor <NUM> shakes.

The degree of the surrounding plate <NUM> protruding from the top surface of the chassis <NUM> is not limited, as long as the cushion pad <NUM> can be limited and is not interfered with other components.

The surrounding plate <NUM> and the chassis <NUM> can be integrated. For example, the surrounding plate <NUM> and the chassis <NUM> can be integrated by injection molding. The surrounding plate <NUM> can be connected to the chassis <NUM> through fasteners such as the screws, which will not be limited here.
