The latching assembly is used for latching the negative pressure assembly with the tray. The negative pressure assembly is separable from the support assembly, so that the negative pressure assembly latched with the tray is separable from the device for assembly and disassembly.

Referring to <FIG>, a support assembly includes a first support member <NUM> and a locking assembly <NUM>. A device for assembly and disassembly includes a frame, and the first support member <NUM> is connected to the frame of the device for assembly and disassembly. The first support member <NUM> is provided as a support plate. The locking assembly <NUM> includes a locking driver <NUM> and a locking connection structure <NUM>, the locking driver <NUM> is connected with the first support member <NUM>, the locking connection structure <NUM> is connected with the locking driver <NUM>, and the locking connection structure <NUM> is used to support a negative pressure assembly for connecting the negative pressure assembly to the device for assembly and disassembly. It should be understood that the connection between the locking connection structure <NUM> and the negative pressure assembly may be released to separate the negative pressure assembly from the device for assembly and disassembly.

Specifically, under actuation of the locking driver <NUM>, the locking connection structure <NUM> can be moved in a second direction to close to the negative pressure assembly. The locking connection structure <NUM> is connected with the negative pressure assembly to function as a support. Accordingly, in a case that the locking connection structure <NUM> is moved reversely, the locking connection structure <NUM> is moved away from the negative pressure assembly to separate from the negative pressure assembly.

It should be understood that the bearing assembly includes a bearing member <NUM> for a carrying tray. The bearing member <NUM> is provided as a bearing plate, and is positioned below the first support member <NUM>. Further, at least one of the bearing member <NUM> and the first support member <NUM> can be raised and lowered in the first direction so that the tray and the negative pressure assembly are brought close to or away from each other. The first direction is a vertical direction.

Referring to <FIG>, the latching assembly includes a first connection structure <NUM> for connecting the negative pressure assembly, a second connection structure <NUM> for connecting the tray, and a movable connection structure <NUM> for movably connecting with the first connection structure <NUM> and for fastening with the second connection structure <NUM>. Specifically, the first connection structure <NUM> is connected to the second connection structure <NUM> by the movable connection structure <NUM> so as to latch the latching assembly, thereby realizing latching and fixing between the negative pressure assembly and the tray, and keeping the negative pressure assembly in engagement with the battery in the tray. It should be understood that the latching connection between the movable connection structure <NUM> and the second connection structure <NUM> may be released to unlatch the latching assembly, so that the negative pressure assembly is separated from the tray.

Further, under actuation of the locking driver <NUM>, the locking connection structure <NUM> can exert a force on the movable connection structure <NUM>, so that the locking connection structure <NUM> can move the movable connection structure <NUM> in the second direction. As such, the latching assembly can synchronously latch the negative pressure assembly with the tray during the separate of the locking connection structure <NUM> from the negative pressure assembly. Alternatively, the latching assembly can synchronously unlatch during the connection of the locking connection structure <NUM> to the negative pressure assembly. It should be understood that the locking connection structure <NUM> can: lock and connect the negative pressure assembly with the device for assembly and disassembly, and unlock and separate the negative pressure assembly from the device; and latch or unlatch the negative pressure assembly with the tray.

Specifically, in a case that the locking connection structure <NUM> is gradually moved away from the negative pressure assembly, the latching connection between the movable connection structure <NUM> and the second connection structure <NUM> is performed while being driven by the locking connection structure <NUM>, thereby synchronous latching of the latching assembly. Accordingly, in a case that the locking driver <NUM> drives the locking connection structure <NUM> to gradually approach and support the negative pressure assembly, the locking connection structure <NUM> can also move the movable connection structure <NUM> at the same time, so that the latching connection between the movable connection structure <NUM> and the second connection structure <NUM> is released, thereby realizing synchronous unlatching of the latching assembly.

It should be understood that the connection between the locking connection structure <NUM> and the movable attachment structure <NUM> may be released, so that the latching assembly is separated from the locking assembly <NUM>. In this case, since the tray is latched and connected to the negative pressure assembly before, the tray and the negative pressure assembly can move together.

In an embodiment, the first connection structure <NUM> is provided with a recessed latching region <NUM>, the second connection structure <NUM> is provided with a latching connection end <NUM>, and the latching connection end <NUM> can extend into the latching region <NUM> in the first direction as the tray rises in the first direction with the bearing member <NUM>. It should be understood that the shape of the latching connection end <NUM> matches the shape of the latching region <NUM>, thereby preventing the latching connection end <NUM> from shaking and offsetting in the latching region <NUM>, thereby improving stability.

Referring to <FIG>, the latching connection end <NUM> is provided with a recessed latching connection region <NUM>, and the movable connection structure <NUM> enters the latching connection region <NUM> as the tray rises in the first direction with the bearing member <NUM>. Further, after the tray is raised to the position to connect with the negative pressure assembly, the movable connection structure <NUM> is moved to fasten with the inner wall of the latching connection region <NUM>, or the movable connection structure <NUM> is released the fastening from the inner wall of the latching connection region <NUM>.

It should be understood that after the movable connection structure <NUM> is released the fastening from the inner wall of the latching connection region <NUM>, the tray is lowered in the first direction with the bearing member <NUM>, the latching connection end <NUM> is withdrawn from the latching region <NUM>, and the movable connection structure <NUM> is withdrawn from the latching connection region <NUM>. As such, the movable connection structure <NUM> is released from the second connection structure <NUM> so that the tray is separated from the negative pressure assembly.

In an embodiment, the latching connection region <NUM> extends through the latching connection end <NUM> in the second direction, and the movable connection structure <NUM> is provided as a rod-like structure. On the first connection structure <NUM>, the axial direction of the movable connection structure <NUM> is provided as the second direction, and the movable connection structure <NUM> can be reciprocated in the second direction, so that the movable connection structure <NUM> can be reciprocated in the latching connection region <NUM>. It should be understood that the movable connection structure <NUM> is moved in the second direction, and the relative positions of the movable connection structure <NUM> and the latching connection region <NUM> can be changed to latch or unlatch the movable connection structure <NUM> with the latching connection region <NUM>.

Further, the side wall of the latching connection region <NUM> is provided with a first avoidance region <NUM>, and the first avoidance region <NUM> extends through the side wall of the latching connection region <NUM> in the first direction. Both ends of the first avoidance region <NUM> extend to the edges of the latching connection region <NUM> in the second direction, respectively. Referring to <FIG>, the first avoidance region <NUM> defines an opening at the latching connection end <NUM>.

It should be understood that, in the case where the latching connection end <NUM> is withdrawn from the latching region <NUM> in the first direction and the latching connection end <NUM> is separated from the latching region <NUM>, the movable connection structure <NUM> is withdrawn from the latching connection region <NUM> through the first avoidance region <NUM>. As such, the movable connection structure <NUM> is released from the second connection structure <NUM>. Accordingly, in a case that the latching connection end <NUM> enters the latching region <NUM> in the first direction, the movable connection structure <NUM> enters the latching connection region <NUM> through the first avoidance region <NUM>.

Referring to <FIG>, the movable connection structure <NUM> includes a fasten section <NUM> and an avoidance section <NUM>, and the fasten section <NUM> and the avoidance section <NUM> are arranged along the axial direction of the movable connection structure <NUM>. The fasten section <NUM> is connected with the avoidance section <NUM>, the fasten section <NUM> can be fastened with the inner wall of the latching connection region <NUM>, and the avoidance section <NUM> can be separated from the first avoidance region <NUM>. It should be understood that, as the movable connection structure <NUM> is moveable in the second direction, the fasten section <NUM> is moved to the latching connection region <NUM> for latching, or the avoidance section <NUM> is moved to the latching connection region <NUM> for unlatching.

Further, the diameter of the fasten section <NUM> is greater than the diameter of the avoidance section <NUM>. Specifically, the movable connection structure <NUM> is provided as a stepped shaft or cylindrical bolt, and the cross-sections of the fasten section <NUM> and the avoidance section <NUM> are circular. Alternatively, for ease of processing, the cross-section of the fasten section <NUM> is rectangular or strip-shaped, and the cross-section of the avoidance section <NUM> is circular. It should be understood that the width between the two opposing side walls of the first avoidance region <NUM> is not less than the diameter of the avoidance section <NUM>, and the width between the two opposing side walls of the first avoidance region <NUM> is less than the diameter of the fasten section <NUM>.

Referring to <FIG>, the latching connection region <NUM> is provided as a circular groove, and the diameter of the cross-section of the latching connection region <NUM> is equal to or slightly greater than the diameter of the fasten section <NUM>, so that the gap between the outer peripheral contour of the fasten section <NUM> and the inner wall of the latching connection region <NUM> is reduced, thereby preventing vibration, and improving the stability of the fastening. Further, the width between the two opposite side walls of the first avoidance region <NUM> is less than the diameter of the cross-section of the latching connection region <NUM>. In this case, a limiting structure is defined between the side walls of the first avoidance region <NUM> and the side walls of the fasten region <NUM>. The limiting structure abuts against the side of the fasten section <NUM>, so that the movable connection structure <NUM> can be prevented from separating from the first avoidance region <NUM> and the second connection structure <NUM>, thereby realizing fastening.

As an alternative, in some examples, the cross-section of the latching connection region <NUM> is provided as a regular polygon, and in this case, the diameter of the latching connection region <NUM> refers to the diameter of the inscribed circle of the regular polygon. In some examples, the cross-sections of the fasten section <NUM> and the avoidance section <NUM> are provided as regular polygons, and in this case the diameters of the fasten section <NUM> and the avoidance section <NUM> refer to the diameters of the circumcircles of the regular polygons.

In an embodiment, the latching assembly includes an elastic member connected to the movable connection structure <NUM>, and the elastic member can exert a force on the movable connection structure <NUM> and the first connection structure <NUM>, respectively. Specifically, in the second direction, the elastic member can exert a reverse elastic force to the movable connection structure <NUM> in a case that the avoidance section <NUM> is moved toward the latching connection region <NUM>. It should be understood in a case that the latching assembly is latched, the elastic member can prevent the avoidance section <NUM> of the movable connection structure <NUM> from moving to the first avoidance region <NUM>, thereby preventing accidental unlatching.

Further, the elastic member is provided as a compression spring, and the elastic member is sleeved on the movable connection structure <NUM>. Specifically, the movable connection structure <NUM> includes a connecting section <NUM> on which the elastic member is sleeved. In connection with <FIG>, in the second direction, the connecting section <NUM>, the avoidance section <NUM>, and the fasten section <NUM> are sequentially connected. The fasten section <NUM> is close to the first end of the movable connection structure <NUM>, and the connecting section <NUM> is close to the second end of the movable connection structure <NUM>.

As the locking connection structure <NUM> moves the movable connection structure <NUM>, the locking connection structure <NUM> is connected with the second end of the movable connection structure <NUM>. Specifically, in a case that the movable connection structure <NUM> is released from fastening with the second connection structure <NUM> under actuation of the locking connection structure <NUM>, the direction of the force exerted by the locking connection structure <NUM> on the movable connection structure <NUM> is from the second end of the movable connection structure <NUM> to the first end of the movable connection structure <NUM> in the second direction. The locking connection structure <NUM> pushes the movable connection structure <NUM>, and the avoidance section <NUM> in the movable connection structure <NUM> moves to the locking connection region <NUM> of the locking connection end <NUM>. At this time, since the elastic member is in a compressed state, and the elastic force exerted by the elastic member on the movable connection structure <NUM> is from the first end to the second end. In a case that the movable connection structure <NUM> is latched and fastened with the second connection structure <NUM> as the locking connection structure <NUM> is pulled in the reverse direction, the movable connection structure <NUM> is moved, and the fasten section <NUM> is moved to the latching connection region <NUM> of the latching connection end <NUM>. At this time, the elastic member can prevent the avoidance section <NUM> of the movable connection structure <NUM> from moving to the first avoidance region <NUM>, thereby preventing an accidental unlatching.

In some examples, the first connection structure <NUM> is provided with a mounting hole extending in the second direction, specifically, the mounting hole extends through side walls on both sides of the latching region <NUM>. It should be understood that the movable connection structure <NUM> is inserted into the mounting hole. On the side of the first connecting structure <NUM> outside the second end of the movable connecting structure <NUM>, an end of the elastic member abuts against the outer side of the first connecting structure <NUM>, and the other end of the elastic member exerts a force on the movable connection structure <NUM> to generate a force in the second direction from the first end to the second end of the movable connection structure <NUM>.

Alternatively, the mounting hole may be designed to extend through the side walls of the latching region <NUM> close to the second end of the movable connection structure <NUM>, while the side walls of the latch region <NUM> close to the first end of the movable connection structure <NUM> is not extended by the mounting hole. The depth of the hole formed in the side walls of the latching region <NUM> close to the first end of the movable connection structure <NUM> is sufficient to receive the fasten section <NUM>.

In an embodiment, the movable connection structure <NUM> is provided with an abutting region <NUM>, and the abutting region <NUM> is close to the second end of the movable connection structure <NUM>. In the case where the locking connection structure <NUM> is connected to the movable connection structure <NUM>, the locking driver <NUM> exerts a force on the abutting region <NUM> through the locking connection structure <NUM> to move the movable connection structure <NUM>.

The abutting region <NUM> is positioned on the side of the movable connecting structure <NUM>, and in particular, the abutting region <NUM> includes a recessed shoulder or protruding annular flange, it should be understood that the recessed shoulder or protruding annular flange is positioned on the side of the connecting section <NUM> on the movable connecting structure <NUM>. Referring to <FIG>, two protruding annular flanges are provided on the side adjacent to the second end of the movable connecting structure <NUM>, and the region between the two annular flanges serves as the abutting region <NUM>. The locking connecting structure <NUM> can exert a force on the annular flanges on the side of the abutting region <NUM> under the actuation of the locking driver <NUM>.

It should be understood that in some examples, where the movable connection structure <NUM> is provided with the elastic member, the annular flange of the abutting region <NUM> may abut against the elastic member, so that the elastic member exerts an elastic force on the movable connection structure <NUM>. Specifically, the elastic member is positioned between the annular flange and the outer side of the first connecting structure <NUM>, and the force of the elastic member to the annular flange is directed in the second direction from the first end of the movable connecting structure <NUM> to the second end of the movable connecting structure <NUM>.

Further, the locking connection structure <NUM> is provided with a locking fasten region <NUM> corresponding to the abutting region <NUM>, and the locking fasten region <NUM> is recessed on the locking connection structure <NUM>. Specifically, the locking fasten region <NUM> is recessed on the locking connection structure <NUM> in a direction away from the tray. It should be understood that the inner wall of the locking fasten region <NUM> abuts against the side of the connection section <NUM> at the abutting region <NUM>, thereby preventing the locking connection structure <NUM> from being offset from the movable connection structure <NUM> and improving the stability. Generally, the battery is positioned below the suction nozzle of the negative pressure assembly, and the battery is moved to the negative pressure assembly and engaged with the negative pressure assembly, thus, the lower portion of the locking connection structure <NUM> is used to abut against the movable connection structure <NUM>. Accordingly, the locking fasten region <NUM> is defined in a recessed shape on the lower side of the locking connection structure <NUM>.

In some examples, in a case that the abutting region <NUM> is provided as a shoulder defined by the side depression of the connecting section <NUM>, in this case, it is necessary to provide an additional annular flange on the side of the connecting section <NUM> for abutting the elastic member, and the annular flange is positioned between the outer side of the first connecting structure <NUM> and the abutting region <NUM>.

In an embodiment, the locking assembly <NUM> includes a locking guide structure <NUM> slidably connected to the locking connection structure <NUM>. It should be understood that under the actuation of the locking driver <NUM>, the locking connection structure <NUM> moves along the locking guide structure <NUM> to approach or away from the negative pressure assembly to improve the smoothness of movement of the locking connection structure <NUM> and prevent offsetting.

Specifically, the locking guide structure <NUM> is fixedly connected to the housing of the locking driver <NUM>, and further, the locking guide structure <NUM> includes a guide rail or a guide groove.

In an embodiment, the device for assembly and disassembly includes a stopper <NUM>. The positions of the movable connection structure <NUM> and the locking connection structure <NUM> are accurately positioned by the stopper <NUM> in a case where the negative pressure assembly and the tray need to be unlatched. As such, the locking connection structure <NUM> can move the movable connection structure <NUM>. Specifically, the lower end of the stopper <NUM> is used to abut one of the negative pressure assembly, the tray, and the bearing member <NUM>, when the tray and the negative pressure assembly as a whole is raised to the unlatched position. At this time, the movable connection structure <NUM> is connected to the locking connection structure <NUM>, and specifically, the side of the connecting section <NUM> at the abutting region <NUM> is in contact with the inner wall of the locking fasten region <NUM>.

In some examples, the stopper <NUM> is provided as a stopping post, and the upper end of the stopping post is connected to the frame or the first support member <NUM>.

As an alternative, the upper end of the stopper <NUM> may be used to abut the first support member <NUM> when the tray and the negative pressure assembly as a whole is raised to the unlatched position. In this case, the stopper <NUM> is connected to the bearing member <NUM>, specifically, the stopper <NUM> is provided on the upper side of the bearing member <NUM>, and the upper end of the stopper <NUM> is used to abut against the lower side of the first support member <NUM>.
