Description

Technical Field

[0001] This application belongs to the field of battery module cleaning technology, and more specifically, relates to a cleaning device. Background Technology

[0002] With the rapid development of the new energy industry, customers have increasingly higher requirements for battery modules. Battery modules typically require heat dissipation components, such as heating plates or heating films, to be attached to their sides for heat dissipation. Existing products usually use adhesive to bond the heat dissipation components to the sides of the battery module. This satisfies the bonding requirements between the heat dissipation components and the battery module while effectively reducing the production cost of the battery module.

[0003] Before the heat sink is attached to the battery module, the sides of the battery module need to be cleaned using cleaning equipment. However, in order to adapt to different market demands, the sizes of various battery modules are quite diverse. The existing cleaning equipment has poor versatility and cannot meet the diverse needs of battery modules, resulting in increased cleaning costs for battery modules. Utility Model Content

[0004] This application provides a cleaning device to improve the versatility of the cleaning equipment and save on the cleaning cost of battery modules.

[0005] The technical solution adopted in this application is as follows: This application provides a cleaning device for cleaning the sides of a battery module. The cleaning device includes a base, a motion platform, and a cleaning mechanism. The base is provided with a cleaning station for placing the battery module. The motion platform is disposed on the base and spaced apart from the cleaning station. The cleaning mechanism includes a support, two sets of cleaning heads, and a first motion component. The support is disposed on the motion platform. The two sets of cleaning heads are disposed on the support and spaced apart relative to each other along a first direction to form a first clearance space for avoiding the battery module. The motion platform is used to drive the support to move relative to the base so that the cleaning station passes through the first clearance space. The two sets of cleaning heads clean the two sides of the battery module respectively. The first motion component is disposed on the support and is drively connected to at least one of the two sets of cleaning heads. The first motion component is used to drive the cleaning head to move along the first direction to adjust the interval between the two sets of cleaning heads.

[0006] In some embodiments, the support includes a connecting portion and two sets of bifurcated portions. Each bifurcated portion includes a first end and a second end. The first end is connected to the connecting portion, and the second end extends along a second direction and toward a main direction away from the connecting portion. The two sets of bifurcated portions are spaced apart along a first direction to form a second clearance space. A cleaning head is disposed at the second end. The motion platform includes: a second motion component, spaced apart from the cleaning station along the second direction, and the second motion component passes through the second clearance space; and a third motion component, disposed on the side of the second motion component away from the base. A connecting portion is disposed on the third motion component and is drively connected to the third motion component. The second motion component is used to drive the third motion component to move along a third direction, and the third motion component is used to drive the support to move along the second direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0007] In some implementations, the distance between the two bifurcated portions gradually increases along the main direction.

[0008] In some embodiments, the base is provided with at least two cleaning stations spaced apart along a first direction, and the motion platform further includes a fourth motion component, which is disposed on the base and spaced apart from the cleaning stations. A second motion component is disposed on the fourth motion component, and the fourth motion component is used to drive the second motion component to move along the first direction, so as to drive the two sets of cleaning heads to the corresponding cleaning stations.

[0009] In some embodiments, the base is also provided with a transport channel corresponding to the number of cleaning stations. The transport channel passes through the cleaning stations. The cleaning equipment also includes a transport mechanism corresponding to the number of transport channels. The transport mechanism is provided in the transport channel and is used to transport the battery module along the transport channel to the cleaning station.

[0010] In some embodiments, the fourth motion component includes: two sets of support components, spaced apart along a third direction, with both sets of support components uniformly connected to the base and spanning above two sets of transport channels. Along the third direction, the cleaning station is located between the two sets of support components. A second motion component is movably connected between the two sets of support components and is configured to move relative to the support components along a first direction. The support components support the second motion component above the cleaning station and provide motion guidance for the second motion component along the first direction. A drive component is disposed on either of the two sets of support components and is drively connected to the second motion component to drive the second motion component to move along the first direction.

[0011] In some embodiments, the cleaning equipment further includes a lifting mechanism disposed at the cleaning station and located below the transport mechanism in a second direction, for lifting the battery module away from the transport mechanism in response to the battery module moving to the cleaning station, so as to position the battery module at the cleaning station.

[0012] In some embodiments, the lifting mechanism includes: a locking mechanism; a positioning plate disposed below the transport mechanism along a second direction, the positioning plate including a first side and a second side disposed at a distance from each other along a third direction; and a driving mechanism, throttle-connected to the positioning plate and disposed on the side of the positioning plate opposite to the transport mechanism; wherein the transport mechanism is used to transport the battery module from the first side to the second side, the locking mechanism is used to stop the battery module above the positioning plate in response to the battery module being transported between the first side and the second side, and the driving mechanism is used to drive the positioning plate to move along the second direction to lift the battery module away from the transport mechanism.

[0013] In some embodiments, the locking mechanism includes: a first locking assembly, comprising a check seat, a check block, and an elastic element. The check seat is disposed on a first side. The check block includes a connecting end and a check end connected to the connecting end. The connecting end is rotatably connected to the check seat. The check end is provided with a guide ramp and a stop surface adjacent to the guide ramp. The guide ramp, the stop surface, and the first side are sequentially arranged along a third direction. The elastic element is disposed between the check end and the check seat, and abuts against the check seat and the check end respectively, so that the guide ramp and the stop surface protrude relative to the positioning plate along a second direction. When the assembly moves from the first side to the second side, the guide ramp can be pressed against by the battery module to guide the check seat to rotate relative to the check seat, so as to allow the battery module to pass through. When the battery module moves between the first side and the second side, the stop surface can abut against the battery module to limit the rebound of the battery module. The second locking assembly includes a limiting block and a driving member pulsatorically connected to the limiting block. The driving member is used to drive the limiting block to move relative to the positioning plate in a second direction in response to the battery module moving between the first side and the second side, so that the limiting block is at least partially protruding relative to the positioning plate to stop the battery module.

[0014] In some embodiments, the first motion component includes two sets of sub-motion components, which are respectively disposed at corresponding second ends and are respectively connected to corresponding cleaning heads in a transmission manner; the cleaning mechanism further includes two rangefinders, which are respectively disposed at corresponding second ends. The rangefinders are used to obtain distance feedback information between the cleaning head and the side of the battery module, and the sub-motion components are used to adjust the working distance between the cleaning head and the side of the battery module in real time based on the distance feedback information.

[0015] The beneficial effects of this application are:

The cleaning mechanism includes a support, two sets of cleaning heads, and a first motion component. The support is mounted on the motion platform. The two sets of cleaning heads are mounted on the support and spaced apart relative to each other along a first direction to form a first clearance space for avoiding the battery module. The motion platform drives the support to move relative to the base so that the cleaning station passes through the first clearance space. The two sets of cleaning heads clean the two sides of the battery module respectively. The first motion component is mounted on the support and is drively connected to at least one of the two sets of cleaning heads. The first motion component drives the cleaning head to move along the first direction to adjust the distance between the two sets of cleaning heads.

[0017] The cleaning mechanism is equipped with a first motion component, which can drive the cleaning head to move along a first direction.

Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] Please see Figure 1 and Figure 2 The cleaning equipment 10 provided in this application embodiment will now be described in detail. The cleaning equipment 10 provided in this application is mainly used for cleaning the sides of battery modules, providing a better adhesion base for side adhesive processes of battery modules, such as the adhesive process of heat sink components, so as to increase the stability of side adhesive application of battery modules.

[0036] Please continue reading Figure 1 and Figure 2 See also Figure 3 The cleaning equipment 10 includes a base 100, a motion platform 200, and a cleaning mechanism 300. The base 100 is provided with a cleaning station (not shown in the figure) for placing battery modules. The motion platform 200 is set on the base 100 and is spaced apart from the cleaning station. The cleaning mechanism 300 includes a bracket 310, two sets of cleaning heads 320, and a first motion component 330.

[0037] The support 310 is mounted on the motion platform 200. Two sets of cleaning heads 320 are both mounted on the support 310 and spaced apart along a first direction x1 to form a first clearance space 321 for avoiding the battery module. The motion platform 200 drives the support 310 to move relative to the base 100, allowing the cleaning station to pass through the first clearance space 321. The two sets of cleaning heads 320 clean the two sides of the battery module respectively. First motion components 330 are both mounted on the support 310 and are drively connected to at least one of the two sets of cleaning heads 320. The first motion components 330 drive the cleaning heads 320 to move along the first direction x1, adjusting the distance between the two sets of cleaning heads 320.

[0038] Specifically, the base 100 is a component that supports the entire device. The motion platform 200 and the cleaning mechanism 300 are integrally mounted on the base 100, which has a cleaning station. The cleaning head 320 is a cleaning component with cleaning function, such as a plasma cleaner. Using a plasma cleaner to clean the battery module can activate the surface of the battery module being cleaned, thereby increasing the adhesion performance of the battery module and improving the stability of the adhesive on the side of the battery module. Of course, in some embodiments, other types of components with cleaning function can also be used, which will not be described in detail here.

[0039] Two sets of cleaning heads 320 and the first motion component 330 are mounted on the motion platform 200 via a bracket 310. After the battery module is placed in the cleaning station, the motion platform 200 can move the cleaning mechanism 300 as a whole to the cleaning station and position the cleaning heads 320 and the battery module. After positioning, the battery module is located between the two sets of cleaning heads 320, that is, the battery module is located within the first clearance space 321. The motion platform 200 further drives the cleaning mechanism 300 to move, thereby driving the cleaning heads 320 to move relative to the side of the battery module, so that the cleaning heads 320 can clean each area of ​​the side of the battery module. The two sets of cleaning heads 320 can clean the two sides of the battery module respectively, thereby effectively improving the cleaning efficiency of the cleaning equipment 10. Furthermore, the cleaning mechanism 300 is also equipped with a first motion component 330, which can drive the cleaning head 320 to move along the first direction x1. This effectively improves the versatility of the cleaning mechanism 300, so as to meet the diversified needs of the battery module and effectively improve the cleaning effect of the cleaning mechanism 300 on the battery module. This effectively saves the cleaning cost of the battery module and effectively improves the cleaning effect of the cleaning equipment 10 on the battery module.

[0040] Taking the first motion component 330 being connected to two sets of cleaning heads 320 as an example, for different types of battery modules, the spacing between the two sides of the battery module varies greatly. After configuring the first motion component 330 in the cleaning mechanism, during the positioning of the battery module and the cleaning head 320, the spacing between the two sets of cleaning heads 320 can be adjusted via the first motion component 330, allowing the battery module to smoothly pass through the first clearance space 321, thereby effectively increasing the versatility of the cleaning mechanism 300. For the same type of battery module, the spacing between the two sides of the battery module may be uneven. After configuring the first motion component 330 in the cleaning mechanism, during the positioning of the battery module and the cleaning head 320, the working distance between the corresponding cleaning head 320 and the side of the battery module can be adjusted in real time via the first motion component 330, so that the working distance between the cleaning head 320 and each area of ​​the side of the battery module meets the optimal cleaning distance of the cleaning head 320, thereby effectively improving the cleaning effect of the cleaning equipment 10 on the battery module. Of course, the first motion component 330 can achieve the above-mentioned effect by simply connecting to at least one of the two sets of cleaning heads 320, which will not be elaborated on here.

[0041] Please see Figure 3 The cleaning mechanism 300 also includes two sets of protective covers 340, which are placed around the outer periphery of the cleaning head 320 to protect the cleaning head 320 and reduce the risk of the cleaning head 320 being damaged.

[0042] The protective cover 340 described in the above embodiment is provided with a dust guide channel (not shown in the figure) that communicates with the covering space of the protective cover 340. The cleaning equipment 10 also includes a dust suction mechanism, which is connected to the dust guide channel and is used to remove dust generated by the cleaning head 320 during operation.

[0043] Please see Figure 3The bracket 310 described in the above embodiment includes a connecting portion 311 and two sets of bifurcated portions 312. Each bifurcated portion 312 includes a first end (not shown) and a second end (not shown). The first end is connected to the connecting portion 311, and the second end extends along a second direction x2 and in a direction away from the main direction of the connecting portion 311. The two sets of bifurcated portions 312 are spaced apart along a first direction x1 to form a second clearance space 313. A cleaning head 320 is disposed at the second end. The motion platform 200 includes a second motion component 210 and a third motion component 220. The second motion component 210 is spaced apart from the cleaning station along the second direction x2, and the second motion component 210 passes through the second clearance space 313. The third motion component 220 is disposed on the side of the second motion component 210 away from the base 100. The connecting part 311 is disposed on the third motion component 220 and is connected to the third motion component 220 in a transmission manner. The second motion component 210 is used to drive the third motion component 220 to move along the third direction x3. The third motion component 220 is used to drive the bracket 310 to move along the second direction x2. The first direction x1, the second direction x2 and the third direction x3 are arranged perpendicular to each other.

[0044] Specifically, the second direction x2 is the spacing direction between the second motion component 210 and the cleaning station. Along the second direction x2, the second motion component 210 and the cleaning station have the shortest spacing distance. In this document, the second direction x2 is the direction parallel to the direction of gravity. Of course, in other embodiments, depending on the placement of the cleaning equipment or the overall structure, the second direction x2 can also be arranged in other ways, which will not be described in detail here.

[0045] The bracket 310 has a bifurcated structure, comprising two bifurcated portions 312. This allows the second moving component 210 to pass between the two bifurcated portions 312, i.e., between the second clearance spaces 313, so that the bracket 310 can move relative to the second moving component 210 along the second direction x2 under the drive of the third moving component 220. Furthermore, the bifurcated structure of the bracket 310 allows the two sets of cleaning heads 320 to be symmetrically arranged on both sides of the second moving component 210, thus effectively improving the stability of the cleaning mechanism 300 as a whole when moving relative to the second moving component 210.

[0046] In this embodiment, the bracket 310 has a symmetrical structure, which allows the cleaning mechanism 300 to be symmetrically arranged on both sides of the second motion component 210. Both the second motion component 210 and the third motion component 220 are linear motor motion components that can be driven along a third direction x3. Of course, in other embodiments, the second motion component 210 can also be other types of linear motion mechanisms, such as cylinder piston motion components, etc., which will not be described in detail here.

[0047] Please see Figure 3Along the main direction described in the above embodiment, the distance between the two sets of bifurcated portions 312 gradually increases. Specifically, the main direction described above is the direction in which the second end of the bifurcated portion 312 extends relative to the first end of the bifurcated portion 312. It can be understood that the two sets of bifurcated portions 312 are configured in accordance with the principle of the main direction assembly, that is, the distance between the two sets of bifurcated portions 312 gradually increases along the main direction as described above. This can effectively prevent motion interference between the second moving component 210, the bracket 310, and the cleaning head 320, while also effectively reducing the overall structural size of the cleaning mechanism 300.

[0048] Please see Figure 3 The first motion component 330 described in the above embodiment includes two sets of sub-motion components 330a, which are respectively disposed at their respective second ends and are respectively connected to the corresponding cleaning head 320 in a transmission manner; the cleaning mechanism 300 also includes two rangefinders, which are respectively disposed at their respective second ends. The rangefinders are used to obtain distance feedback information between the cleaning head 320 and the side of the battery module, and the sub-motion components 330a are used to adjust the interval distance between the cleaning head 320 and the side of the battery module in real time based on the distance feedback information.

[0049] Specifically, in this embodiment, the first motion component 330 includes two sets of sub-motion components 330a, so that the first motion component 330 can be drivenly connected to the two sets of cleaning heads 320 respectively. Of course, in some embodiments, the first motion component 330 can also be other types of motion components, which will not be described in detail here. The cleaning mechanism 300 is also equipped with two rangefinders. Each rangefinder is used to obtain distance feedback information between the corresponding cleaning head 320 and the corresponding side of the battery module. The sub-motion components 330a adjust the working distance between the cleaning head 320 and the side of the battery module in real time based on the distance feedback information obtained by the rangefinders, thereby improving the cleaning effect of the cleaning mechanism 300 on the battery module.

[0050] The sub-motion assembly 330a may consist of a cylinder, a piston, and a slider, which are moving parts that can drive the cleaning head 320 to move along the first direction x1. The specific settings can be configured according to actual needs, which will not be elaborated in detail here.

[0051] Please see Figure 2The base 100 described in the above embodiment is provided with at least two cleaning stations spaced apart along the first direction x1. The motion platform 200 also includes a fourth motion component 230, which is disposed on the base 100 and spaced apart from the cleaning stations. A second motion component 210 is disposed on the fourth motion component 230. The fourth motion component 230 is used to drive the second motion component 210 to move along the first direction x1, so as to drive the two sets of cleaning heads 320 to the corresponding cleaning stations.

[0052] Taking two cleaning stations set on the base 100 as an example, the two cleaning stations are set at intervals along the first direction x1. The fourth motion component 230 can drive the second motion component 210 to move between the two cleaning stations, so as to drive the two sets of cleaning heads 320 to move to the corresponding cleaning stations. In this way, while the cleaning mechanism 300 cleans the battery module on one cleaning station, it performs preparatory work for cleaning another battery module on the other cleaning station. This allows the cleaning equipment 10 to clean multiple battery modules in an alternating manner at the same time, thereby effectively improving the cleaning efficiency of the cleaning equipment 10.

[0053] Please see Figure 1 The base 100 described in the above embodiment is also provided with a transport channel 110 corresponding to the number of cleaning stations. The transport channel 110 passes through the cleaning stations. The cleaning equipment 10 also includes a transport mechanism corresponding to the number of transport channels 110. The transport mechanism is provided in the transport channel 110 and is used to transport the battery module along the transport channel 110 to the cleaning station.

[0054] Taking the base 100 with two cleaning stations as an example, the base 100 is also equipped with two transport channels 110 and two transport mechanisms. The two transport channels 110 pass through the cleaning stations, and the two transport mechanisms are respectively set in the corresponding transport channels 110. In this way, the two transport mechanisms can be connected to the production lines of two battery modules respectively, and are used to transport the battery modules to be cleaned from each production line to the corresponding cleaning station, thereby effectively improving the cleaning efficiency of the cleaning equipment 10.

[0055] Please see Figure 4The fourth motion component 230 includes two sets of support components 231 and a drive component 232. The two sets of support components 231 are spaced apart along a third direction x3 and are uniformly connected to the base 100, each spanning above the two transport channels 110. Along the third direction x3, the cleaning station is located between the two sets of support components 231. The second motion component 210 is movably connected between the two sets of support components 231. The second motion component 210 is configured to move relative to the support components 231 along a first direction x1. The support components 231 support the second motion component 210 above the cleaning station and provide movement guidance for the second motion component 210 along the first direction x1. The drive component 232 is disposed on either of the two sets of support components 231 and is drively connected to the second motion component 210, driving the second motion component 210 to move along the first direction x1.

[0056] Specifically, the support assembly 231 is a component used to support the drive assembly 232, the second motion assembly 210, the third motion assembly 220, and the cleaning mechanism 300. Two sets of support assemblies 231 are spaced apart along a third direction x3. The second motion assembly 210 is connected between the two sets of support assemblies 231 to form a gantry structure. This effectively reduces the structural complexity of the motion platform 200 while also effectively improving its structural stability. In this embodiment, each set of support assemblies 231 is provided with a guide assembly, such as a guide rail slider assembly. The second motion assembly 210 is movably connected to the support assembly 231 through the guide assembly, thereby improving the motion stability of the second motion assembly 210 relative to the support assembly 231 along the first direction x1.

[0057] Please see Figure 4 In this embodiment, the drive component 232 is a mechanism that achieves transmission by meshing. Taking the example of setting the drive component 232 on only one set of support components 231, specifically, the drive component 232 includes a drive motor 2321, a rack 2320, and a gear meshing with the rack 2320. The gear is set on the output shaft of the drive motor 2321. The drive motor 2321 is fixedly connected to the second motion component 210. The rack 2320 is set on the support component 231. Thus, according to the kinematic laws, under the drive of the drive motor 2321 and the meshing of the rack 2320 and the gear, the drive motor 2321 and the second motion component 210 can move as a whole relative to the support component 231 along the first direction x1.

[0058] Of course, in other embodiments, the drive component 232 may also be configured as a mechanism for transmission in other ways, which will not be described in detail here.

[0059] Please see Figure 1 and Figure 5The cleaning equipment 10 described in the above embodiments also includes a lifting mechanism 400, which is disposed at the cleaning station and located below the transport mechanism along the second direction x2. The lifting mechanism 400 is used to lift the battery module away from the transport mechanism in response to the battery module moving to the cleaning station, so as to position the battery module at the cleaning station.

[0060] Specifically, the lifting mechanism 400 is used in conjunction with the transport mechanism to achieve manual or automatic loading. The lifting mechanism 400 facilitates the positioning of the battery module, reducing the difficulty of positioning the battery module after it is loaded to the cleaning station. In this embodiment, the lifting mechanism 400 is equipped with a sensing device. When the battery module is transported to the cleaning station, the sensing device generates a sensing signal. Based on the sensing signal, the lifting mechanism 400 lifts the battery module away from the transport mechanism and positions the battery module at the cleaning station. This effectively improves the automation level of the cleaning equipment 10, thereby reducing the labor cost of cleaning the battery module.

[0061] Please see Figure 5 The lifting mechanism 400 described in the above embodiment includes a locking mechanism 410, a positioning plate 420, and a driving mechanism 430. The positioning plate 420 is disposed below the transport mechanism along a second direction x2, and includes a first side LB1 and a second side LB2 disposed at a distance from each other along a third direction x3. The driving mechanism 430 is drive-connected to the positioning plate 420 and is disposed on the side of the positioning plate 420 opposite to the transport mechanism. The transport mechanism is used to transport the battery module from the first side LB1 to the second side LB2. The locking mechanism 410 is used to stop the battery module above the positioning plate 420 in response to it being transported between the first side LB1 and the second side LB2. The driving mechanism 430 is used to drive the positioning plate 420 to move along the second direction x2 to lift the battery module away from the transport mechanism.

[0062] Specifically, the locking mechanism 410 allows the battery module to be transported above the positioning plate 420 via the first side LB1 and stops the battery module between the first side LB1 and the second side LB2. The locking mechanism 410 works in conjunction with the positioning plate 420 and the drive mechanism 430. Thus, when the battery module is transported between the first side LB1 and the second side LB2 by the transport mechanism, the locking mechanism 410 can stop the battery module, so that the drive mechanism 430 can drive the positioning plate 420 to stably lift the battery module away from the transport mechanism.

[0063] Please see Figure 5In this embodiment, the positioning plate 420 described in the above embodiments is provided with a relative positioning pin 421, and the lifting mechanism 400 further includes a positioning detection element 440. The positioning plate 420 is provided with a through hole, and the positioning detection element 440 is correspondingly provided with the through hole. The positioning detection element 440 can detect whether the battery module has moved between the first side LB1 and the second side LB2 through the through hole, and generate a positioning signal when the battery module moves between the first side LB1 and the second side LB2. The driving mechanism 430 drives the positioning plate 420 to move along the second direction x2 based on the positioning signal, so that the positioning pin 421 is inserted into the positioning part on the battery module or the positioning part on the positioning module used to support the battery module, while the surface of the positioning plate 420 abuts against the lower surface of the battery module or the lower surface of the positioning module used to support the battery module, so as to lift the battery module as a whole away from the transport mechanism and position the battery module. The number of positioning pins 421 can be two or more. Taking two positioning pins 421 as an example, the two positioning pins 421 are respectively set in the diagonal area of ​​the positioning plate 420, which can effectively improve the positioning stability of the battery module on the positioning plate 420.

[0064] Of course, in other embodiments, the component used to position the battery module is limited to the positioning pin 421, which can be matched with the positioning part on the battery module or the positioning part on the positioning module used to carry the battery module. This will not be described in detail here.

[0065] Please see 5 and Figure 6 The locking mechanism 410 described in the above embodiment includes a first locking component 411 and a second locking component 412. The first locking component 411 includes a check seat 4110, a check block 4111, and an elastic element 4112. The check seat 4110 is disposed on the first side LB1. The check block 4111 includes a connecting end 4111b and a check end 4111a connected to the connecting end 4111b. The connecting end 4111b is rotatably connected to the check seat 4110. The check end 4111a is provided with a guide slope 4111c and a stop surface 4111d adjacent to the guide slope 4111c. The guide slope 4111c, the stop surface 4111d, and the first side LB1 are arranged sequentially along a third direction x3. The elastic element 4112 is disposed on the first side LB1. The guide ramp 4111c and the stop surface 4111d are positioned between the return end 4111a and the check seat 4110, respectively, so that the guide ramp 4111c and the stop surface 4111d protrude relative to the positioning plate 420 along the second direction x2. When the battery module moves from the first side LB1 to the second side LB2, the guide ramp 4111c can be pressed against by the battery module to guide the check seat 4110 to rotate relative to the check seat 4110, so as to allow the battery module to pass through. When the battery module moves between the first side LB1 and the second side LB2, the stop surface 4111d can abut against the battery module to limit the rebound of the battery module.

[0066] The second locking assembly 412 includes a limiting block 4120 and a driving member 4121 pulsatorically connected to the limiting block 4120. The driving member 4121 is used to drive the limiting block 4120 to move relative to the positioning plate 420 along the second direction x2 in response to the battery module moving between the first side LB1 and the second side LB2, so that the limiting block 4120 protrudes at least partially relative to the positioning plate 420 to stop the battery module.

[0067] Specifically, the first locking component 411 achieves forward passage (the first locking component 411 allows the battery module to move along a third direction x3 from the first side LB1 to the second side LB2, which is forward passage) and reverse blocking (when the battery module is located between the first side LB1 and the second side LB2, the first locking component 411 prevents the battery module from rebounding towards the first side LB1, which is reverse blocking) in a purely structural manner. This effectively simplifies the cost of the first locking component 411. The second locking component 412 is a controllable mechanism. For example, the drive component 4121 can be connected to the position detection element 440 described in the above embodiment. The drive component 4121 is used to drive the limit block 4120 to move relative to the positioning plate 420 based on the position signal, so as to stop the battery module between the first side LB1 and the second side LB2. After the battery module is cleaned, the limit block 4120 can also be hidden under the positioning plate 420 based on the drive component 4121. Of course, in other embodiments, the drive unit 4121 can also be controlled manually, which will not be described in detail here.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
