DETAILED DESCRIPTION

[0047] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar elements or elements having the same or similar functions are denoted by the same or similar reference signs throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only for explanation of the present application, and cannot be understood as limiting the present application.

[0048] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0049] In the prior art, in order to fix the battery assembly on the electrical device, the lug and bolt combination is usually used to fix the battery assembly, but the lug on the battery assembly is usually a protruding package, which occupies a lot of space, and when the lug is fixed by the bolt, the battery assembly needs to be supported first, and then the hole position on the lug is aligned and fixed, which is a complex process, resulting in difficulty in fixing the battery assembly.

[0050] At the same time, when the battery assembly is installed on the roof of the vehicle, it is not convenient to connect the bolt, and the appearance of the vehicle is also easy to be damaged during installation, resulting in the problem of scratch on the appearance of the vehicle.

[0051] In order to solve the above problems, as shown in FIGS. 1 and 2, the application provides a fixing module 1000 which can quickly fix and disassemble the battery assembly 3000, and the specific scheme is to provide a clamping assembly 200 on the support 100 of the fixing module 1000, and at least one clamping piece 210 in the clamping assembly 200 is movably arranged on the support 100, so that the clamping assembly 200 can be switched between the clamping state and the separated state. When the battery assembly 3000 needs to be fixed, the movable clamping piece 210 is controlled to move towards the direction of the battery assembly 3000, so that the plurality of clamping pieces 210 of the clamping assembly 200 respectively contact the opposite sides of the battery assembly 3000 in the first direction, achieving the purpose of fixing the battery assembly 3000 and realizing the quick installation and fixation of the battery assembly 3000; when the battery assembly 3000 needs to be disassembled, the movable clamping piece 210 is controlled to move away from the direction of the battery assembly 3000, so that at least one clamping piece 210 is separated from at least one side of the battery assembly 3000 in the first direction, thereby facilitating the movement of the battery assembly 3000, so as to realize the quick disassembly of the battery assembly 3000, thereby facilitating the fixation and disassembly of the battery assembly 3000 and reducing the difficulty of the fixation and disassembly of the battery assembly 3000.

[0052] The fixing module 1000 for fixing the battery assembly 3000 of the embodiment of the application is described below with reference to the drawings of the specification.

[0053] As shown in FIGS. 1 and 2, the fixing module 1000 for fixing the battery assembly 3000 according to the embodiment of the application comprises a support 100 and a clamping assembly 200.

[0054] It should be noted that the battery assembly 3000 mentioned here can be a battery monomer, a battery module or a battery pack, etc.

[0055] The support 100 is adapted to support the battery assembly 3000. The support 100 facilitates the fixing of the battery assembly 3000 by the fixing module 1000, and reduces the difficulty of fixing the battery assembly 3000 while improving the position stability of the battery assembly 3000.

[0056] As shown in FIG. 2, the clamping assembly 200 includes a plurality of clamping members 210, which are spaced apart in the first direction on the support 100. At least one clamping member 210 is movably arranged on the support 100 to switch the clamping assembly 200 between a clamping state and a separation state. In the clamping state, the plurality of clamping members 210 are adapted to contact the opposite sides of the battery assembly 3000 in the first direction respectively to fix the battery assembly 3000. In the separation state, at least one clamping member 210 is separated from at least one side of the battery assembly 3000 in the first direction to make the battery assembly 3000 detachable. Here, when the clamping assembly 200 includes a plurality of clamping members 210, one clamping member 210 of the plurality of clamping members 210 is movably arranged on the support 100, or the plurality of clamping members 210 are movably arranged on the support 100 to switch the clamping assembly 200 between the clamping state and the separation state. Thus, when the battery assembly 3000 needs to be fixed, the movable clamping member 210 can be controlled to move towards the battery assembly 3000 to make the plurality of clamping members 210 of the clamping assembly 200 contact the opposite sides of the battery assembly 3000 in the first direction respectively, so as to fix the battery assembly 3000 and achieve quick installation and fixing of the battery assembly 3000. When the battery assembly 3000 needs to be detached, the movable clamping member 210 can be controlled to move away from the battery assembly 3000 to separate at least one clamping member 210 from at least one side of the battery assembly 3000 in the first direction, so as to facilitate the movement of the battery assembly 3000 and achieve quick detachment of the battery assembly 3000. Thus, the fixing and detachment of the battery assembly 3000 are facilitated, and the difficulty of fixing and detaching the battery assembly 3000 is reduced.

[0057] It should be noted that when at least one clamping member 210 is movably arranged on the support 100, the clamping member 210 is formed as a movable clamping member, and the clamping member 210 that cannot move relative to the support 100 can be understood as a fixed clamping member. The fixed clamping member refers to the clamping member 210 that is fixed on the support 100 and cannot move. When the movable clamping member and the fixed clamping member contact the opposite sides of the battery assembly 3000 in the first direction respectively, the battery assembly 3000 can be fixed. When the movable clamping member is separated from at least one side of the battery assembly 3000 in the first direction, the battery assembly 3000 can be detached, so as to achieve quick detachment and fixing of the battery assembly 3000 and reduce the difficulty of detaching and fixing the battery assembly 3000.

[0058] In some examples, when the plurality of clamping pieces 210 include a movable clamping piece and a fixed clamping piece, when the battery assembly 3000 is arranged on the support 100, the fixed clamping piece is always in contact with one side of the battery assembly 3000 in the first direction, and when the movable clamping piece is controlled to be in contact with the other side of the battery assembly 3000 in the first direction, the plurality of clamping pieces 210 are all in contact with the battery assembly 3000, so as to achieve the purpose of fixing the battery assembly 3000.

[0059] Meanwhile, by fixing the battery assembly 3000 by using the clamping assembly 200, the process of arranging the lifting lug on the battery assembly 3000 and the process of manually locking the bolt are omitted, on the one hand, the occupied space of the battery assembly 3000 is reduced, on the other hand, the installation difficulty of the battery assembly 3000 is reduced, and at the same time, the damage to the electric device 2000 caused by fixing the battery assembly 3000 is avoided to a certain extent.

[0060] It should be noted that the first direction mentioned above can be understood as the Y direction shown in FIG. 2, and when the electric device 2000 is a vehicle, the first direction can also be understood as the left-right direction of the vehicle, i.e., the direction between the driver's seat and the front passenger's seat of the vehicle, that is, the plurality of clamping pieces 210 are arranged on the support 100 in the Y direction.

[0061] In some examples, when it is necessary to fix the battery assembly 3000, the battery assembly 3000 can be arranged on the support 100 first, and then the movable clamping piece 210 is moved to make the plurality of clamping pieces 210 contact the opposite sides of the battery assembly 3000 in the first direction, so as to achieve the purpose of fixing the battery assembly 3000; when it is necessary to disassemble the battery assembly 3000, the movable clamping piece 210 is moved to make the movable clamping piece 210 separate from at least one side of the battery assembly 3000 in the first direction, and then the battery assembly 3000 is moved to achieve the purpose of disassembling the battery assembly 3000.

[0062] In some embodiments, as shown in FIG. 2, the clamping assembly 200 includes two clamping pieces 210, and the two clamping pieces 210 are arranged on the support 100 in the first direction, and at least one clamping piece 210 is movably arranged on the support 100 to form a movable clamping piece, so that the use quantity of the clamping pieces 210 is reduced when the battery assembly 3000 is fixed or released by using the clamping assembly 200, which is beneficial to simplify the structure of the fixing module 1000 and reduce the assembly difficulty and use cost of the fixing module 1000.

[0063] In some embodiments, both of the clamping members 210 are movably arranged on the support member 100, so that both of the clamping members 210 are formed as movable clamping members.

[0064] In other embodiments, one of the clamping members 210 is movably arranged on the support member 100 to be formed as a movable clamping member, and the other of the clamping members 210 is fixedly arranged on the support member 100 to be formed as a fixed clamping member.

[0065] From the above structure, it can be seen that the fixed module 1000 of the embodiments of the present application sets the clamping assembly 200 to replace the conventional bolts to fix the battery assembly 3000. Specifically, at least one clamping member 210 of the clamping assembly 200 is arranged to be a movable clamping member, so that the clamping assembly 200 can be switched between a clamping state and a separation state. Thus, when the battery assembly 3000 needs to be fixed, the movable clamping member can be used to control the clamping assembly 200 to switch to the clamping state, so that the plurality of clamping members 210 respectively contact the opposite sides of the battery assembly 3000 in the first direction to fix the battery assembly 3000, thereby achieving the purpose of fixing the battery assembly 3000. When the battery assembly 3000 needs to be disassembled, the movable clamping member can be used to control the clamping assembly 200 to switch to the separation state, so that the movable clamping member is separated from at least one side of the battery assembly 3000 in the first direction to allow the battery assembly 3000 to be disassembled, thereby achieving the quick fixing and disassembly of the battery assembly 3000 and reducing the difficulty of assembling and disassembling the battery assembly 3000.

[0066] It can be understood that, compared with the prior art of fixing the battery assembly by cooperating with the lifting lugs and bolts, the fixed module 1000 of the present application sets the clamping assembly 200 to fix the battery assembly 3000, which not only makes the installation of the battery assembly 3000 simple and convenient, but also facilitates the disassembly of the battery assembly 3000, so as to achieve the quick installation and quick disassembly of the battery assembly 3000.

[0067] In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0068] In some embodiments, the at least one clamping member 210 is movably arranged on the support member 100 to form a movable clamping member, which is adapted to contact the battery assembly 3000 in the clamping state and is adapted to be separated from the battery assembly 3000 in the separation state. Thus, in the clamping state, the plurality of clamping members 210 can contact the battery assembly 3000 on opposite sides in the first direction, respectively, to fix the battery assembly 3000, and in the separation state, the at least one clamping member 210 is separated from at least one side of the battery assembly 3000 in the first direction, thereby facilitating the movement of the battery assembly 3000 to quickly disassemble the battery assembly 3000, so that the fixing and disassembling of the battery assembly 3000 is convenient and the difficulty of the fixing and disassembling of the battery assembly 3000 is reduced.

[0069] In some embodiments, the clamping member 210 is a clamping plate formed by die casting, which can reduce the difficulty of forming the clamping member 210 and improve the structural strength of the clamping member 210, thereby ensuring that the plurality of clamping members 210 can fix the battery assembly 3000 when contacting the battery assembly 3000 on opposite sides in the first direction, respectively, which can improve the fixing quality while reducing the difficulty of fixing the battery assembly 3000, thereby improving the positional stability of the battery assembly 3000.

[0070] In some embodiments, in combination with FIGS. 1, 2 and 3, the fixing module 1000 further comprises a fixing matching member 300, which is adapted to be arranged between the battery assembly 3000 and the movable clamping member to realize the fixing matching of the battery assembly 3000 and the movable clamping member in the clamping state. Thus, the battery assembly 3000 can be fixed by the clamping assembly 200, which can improve the fixing effect of the clamping assembly 200 while reducing the difficulty of fixing the battery assembly 3000, so that the battery assembly 3000 can be stably arranged on the electric device 2000, which improves the positional stability of the battery assembly 3000 and is beneficial to improve the working performance of the battery assembly 3000.

[0071] In some embodiments, in combination with FIGS. 2 and 3, the fixing matching member 300 comprises a matching groove 310 and a matching protrusion 320, the matching protrusion 320 is fixedly matched in the matching groove 310, and one of the matching groove 310 and the matching protrusion 320 is adapted to be arranged on the battery assembly 3000 and the other is adapted to be arranged on the movable clamping member. Thus, the fixing matching of the battery assembly 3000 and the movable clamping member is realized.

[0072] Here, the matching protrusion 320 can be understood as a ball head, and the matching groove 310 can be understood as a ball hole.

[0073] In some embodiments, as shown in FIGS. 2 and 3, the cooperating groove 310 is arranged on the battery assembly 3000, and the cooperating protrusion 320 is arranged on the mobile holder, so that when the cooperating protrusion 320 is fixedly and cooperatively arranged in the cooperating groove 310, the fixed cooperation between the battery assembly 3000 and the mobile holder is achieved.

[0074] Of course, in some other embodiments, the cooperating groove 310 can be arranged on the mobile holder, and the cooperating protrusion 320 can be arranged on the battery assembly 3000, so that when the cooperating protrusion 320 is fixedly and cooperatively arranged in the cooperating groove 310, the fixed cooperation between the battery assembly 3000 and the mobile holder is achieved.

[0075] In some embodiments, the cooperating groove 310 and the cooperating protrusion 320 are oppositely arranged in the first direction, so that when the mobile holder moves towards the battery assembly 3000 along the first direction, the cooperating protrusion 320 can be fixedly and cooperatively arranged in the cooperating groove 310, so as to achieve the fixed cooperation between the battery assembly 3000 and the mobile holder, and reduce the difficulty of the fixed cooperation between the battery assembly 3000 and the mobile holder.

[0076] In some embodiments, as shown in FIGS. 2 and 3, the fixed cooperation member 300 includes a plurality of fixed cooperation members 300, and the plurality of fixed cooperation members 300 are arranged along a second direction different from the extension direction of the first direction. Here, the second direction can be understood as the X direction shown in FIG. 2. When the electric device 2000 is a vehicle, the second direction can also be understood as the front-rear direction of the vehicle, i.e. the direction between the front and the rear of the vehicle. That is, the plurality of fixed cooperation members 300 are arranged along the X direction, so as to facilitate the fixed cooperation between the battery assembly 3000 and the mobile holder by using the plurality of fixed cooperation members 300, and improve the fixed cooperation strength between the battery assembly 3000 and the mobile holder, thereby improving the position stability of the battery assembly 3000.

[0077] It should be noted that the plurality of fixed cooperation members 300 means that when the cooperating groove 310 is arranged on the battery assembly 3000, the battery assembly 3000 is provided with a plurality of cooperating grooves 310, and the plurality of cooperating grooves 310 are arranged along the second direction (as shown in FIG. 3). Correspondingly, the mobile holder is provided with a plurality of cooperating protrusions 320 corresponding to the plurality of cooperating grooves 310.

[0078] In the description of the present application, the features defined as "first" and "second" can explicitly or implicitly include one or more features, for distinguishing the description features, without order and without difference.

[0079] In some embodiments, as shown in FIG. 2 and FIG. 4, the fixing module 1000 further comprises a driving assembly 400 for driving the moving clamping piece to move in the first direction, so that the clamping assembly 200 can be controlled to switch between the clamping state and the separation state by the moving clamping piece, the switching difficulty of the clamping assembly 200 is reduced, and the fixing and dismounting difficulty of the battery assembly 3000 is further reduced.

[0080] Meanwhile, by setting the driving assembly 400, the automatic movement of the moving clamping piece can be realized, the manual intervention step is simplified, and the fixing and dismounting difficulty of the battery assembly 3000 is further reduced.

[0081] In some embodiments, as shown in FIG. 2 and FIG. 4, the driving assembly 400 comprises a rotating disc 410 and a connecting piece 420, the rotating disc 410 is arranged in the first direction with the moving clamping piece, the opposite ends of the connecting piece 420 are respectively rotatably connected with the rotating disc 410 and the moving clamping piece, and the rotating disc 410 is rotated for driving the moving clamping piece to move in the first direction through the connecting piece 420. Here, when the rotating disc 410 is rotated, the rotating disc 410 can drive the moving clamping piece to move in the first direction through the connecting piece 420, so that the moving clamping piece can contact or separate from the battery assembly 3000, when the moving clamping piece contacts the battery assembly 3000, the plurality of clamping pieces 210 can contact the battery assembly 3000 to fix the battery assembly 3000, and when the moving clamping piece separates from the battery assembly 3000, the battery assembly 3000 can be dismounted, so that the fixing and dismounting difficulty of the battery assembly 3000 is reduced.

[0082] In some embodiments, the opposite ends of the connecting piece 420 are respectively connected with the rotating disc 410 and the moving clamping piece through rotating shafts, so that the rotating connection of the connecting piece 420 with the rotating disc 410 and the moving clamping piece is realized, and the rotating connection difficulty of the connecting piece 420 with the rotating disc 410 and the moving clamping piece is reduced.

[0083] In some examples, when the rotating disc 410 is rotated, the rotating disc 410 can drive the connecting piece 420 to move, because the connecting piece 420 is rotatably connected with the moving clamping piece, so that the moving clamping piece is driven to move in the first direction through the connecting piece 420, and the moving difficulty of the moving clamping piece is reduced.

[0084] Specifically, when the rotating disc 410 rotates clockwise, the rotating disc 410 is used to drive the connecting piece 420 to move towards the direction close to the rotating disc 410, at this time, the connecting piece 420 drives the moving clamping piece to move towards the direction close to the battery assembly 3000, so that the moving clamping piece can be in contact with the battery assembly 3000, and then the plurality of clamping pieces 210 can be in contact with the battery assembly 3000, so as to achieve the purpose of fixing the battery assembly 3000; when the rotating disc 410 rotates counterclockwise, the rotating disc 410 is used to drive the connecting piece 420 to move towards the direction away from the rotating disc 410, at this time, the connecting piece 420 drives the moving clamping piece to move towards the direction away from the battery assembly 3000, so that the moving clamping piece can be separated from the battery assembly 3000, and the battery assembly 3000 is convenient to disassemble.

[0085] In some embodiments, as shown in FIG. 2, FIG. 4 and FIG. 5, the driving assembly 400 further comprises a connecting arm 430, one end of the connecting arm 430 is fixedly connected with the moving clamping piece, and the other end of the connecting arm 430 is rotationally connected with the connecting piece 420, so as to realize the rotational connection between the connecting piece 420 and the moving clamping piece, and reduce the difficulty of the rotational connection between the connecting piece 420 and the moving clamping piece, so that the rotating disc 410 can effectively drive the moving clamping piece to move in the first direction through the connecting piece 420, and the moving difficulty of the moving clamping piece is reduced.

[0086] Here, the fixed connection between the connecting arm 430 and the moving clamping piece can be welding, bonding, etc., and the rotational connection between the connecting arm 430 and the connecting piece 420 can be realized through a rotating shaft.

[0087] Optionally, the driving assembly 400 further comprises a driving motor (not shown in the figure), and an output end of the driving motor is connected with the rotating disc 410, and the driving motor is used to drive the rotating disc 410 to rotate, so as to achieve the purpose of driving the moving clamping piece to move in the first direction.

[0088] In some embodiments, the driving motor is a rotary motor, and the rotary motor is connected with the rotating disc 410, so as to facilitate the driving of the rotating disc 410 to rotate, and reduce the driving difficulty of the rotating disc 410.

[0089] It should be noted that the power source of the rotary motor is the power source built in the power utilization device 2000 itself, and is irrelevant to the power source of the battery assembly 3000, that is, the power source of the battery assembly 3000 does not affect the use of the rotating disc 410.

[0090] Of course, in other embodiments, the driving assembly 400 can only comprise a linear motor, and an output end of the linear motor is directly connected with the moving clamping piece and drives the moving clamping piece to move in the first direction, so as to achieve the purpose of switching the clamping assembly 200 between the clamping state and the separation state by using the moving clamping piece.

[0091] In some embodiments, the plurality of clamping members 210 are movably arranged on the support 100 to form a plurality of moving clamping members. Here, the clamping assembly 200 includes a plurality of clamping members 210, and each of the plurality of clamping members 210 is a moving clamping member. This facilitates the simultaneous contact of the plurality of clamping members 210 of the clamping assembly 200 with the opposite sides of the battery assembly 3000 in the first direction or the simultaneous separation of the plurality of clamping members 210 from the opposite sides of the battery assembly 3000 in the first direction, which facilitates the fixing of the battery assembly 3000 when the plurality of clamping members 210 simultaneously contact the opposite sides of the battery assembly 3000 in the first direction, and facilitates the disassembly of the battery assembly 3000 when the plurality of clamping members 210 simultaneously separate from the opposite sides of the battery assembly 3000 in the first direction, thereby further reducing the difficulty of disassembling and fixing the battery assembly 3000 and achieving the quick disassembly and fixing of the battery assembly 3000.

[0092] In some embodiments, as shown in FIGS. 2 and 4, the clamping assembly 200 includes two clamping members 210, and each of the two clamping members 210 is movably arranged on the support 100 to form a moving clamping member, thereby facilitating the simultaneous contact of the two clamping members 210 with the opposite sides of the battery assembly 3000 in the first direction or the simultaneous separation of the two clamping members 210 from the opposite sides of the battery assembly 3000 in the first direction, thereby reducing the difficulty of disassembling and fixing the battery assembly 3000.

[0093] In some embodiments, as shown in FIGS. 2 and 4, the rotating disc 410 is arranged between adjacent two moving clamping members arranged in the first direction and is connected to the adjacent two moving clamping members through the connecting member 420, and the rotating disc 410 is used to drive the adjacent two moving clamping members to move towards each other or move away from each other through the connecting member 420. Here, when the moving clamping members are a plurality of moving clamping members, the rotating disc 410 is arranged between adjacent two moving clamping members to facilitate the driving of the adjacent two moving clamping members to move towards each other or move away from each other by the rotating disc 410. The moving towards each other means that the adjacent two moving clamping members simultaneously move towards each other, so that the adjacent two moving clamping members can simultaneously move towards the battery assembly 3000 to facilitate the cooperation of the adjacent two moving clamping members in fixing the battery assembly 3000. The moving away from each other means that the adjacent two moving clamping members simultaneously move away from each other, so that the adjacent two moving clamping members can simultaneously move away from the battery assembly 3000 to facilitate the disassembly of the battery assembly 3000.

[0094] Meanwhile, by connecting the rotating disc 410 to two adjacent moving clamping pieces through the connecting pieces 420 respectively, the rotating disc 410 can be used to drive the two adjacent moving clamping pieces to move simultaneously, the number of rotating discs 410 used is reduced, the structure of the fixing module 1000 is simplified, and the use cost of the fixing module 1000 is reduced.

[0095] It can also be understood that, compared with directly driving the moving clamping piece to move in the first direction by using the linear motor, the rotating disc 410 provided in the application can be used to drive two adjacent moving clamping pieces to move simultaneously, that is, one driving piece is used to drive two adjacent moving clamping pieces to move simultaneously, which is convenient for simplifying the number of driving pieces used.

[0096] In some embodiments, as shown in FIG. 4, the driving assembly 400 includes a plurality of connecting pieces 420, and the plurality of connecting pieces 420 are connected with the plurality of moving clamping pieces respectively to achieve the driving of the two adjacent moving clamping pieces to move towards each other or move away from each other by the rotating disc 410 through the connecting pieces 420.

[0097] In some embodiments, the fixing module 1000 further includes a first elastic piece (not shown in the figure), and the first elastic piece is used to drive the moving clamping piece to move in the first direction towards the battery assembly 3000. That is, the first elastic piece is used to drive the moving clamping piece to move in the direction close to the battery assembly 3000, which is convenient for fixing the cooperation protrusion 320 in the cooperation groove 310 and avoiding the cooperation protrusion 320 from moving out of the cooperation groove 310 to a certain extent, thereby facilitating the fixing and cooperation of the battery assembly 3000 and the moving clamping piece by using the fixing and cooperation piece 300, achieving the purpose of fixing the battery assembly 3000 by using the moving clamping piece, improving the position stability of the battery assembly 3000, and reducing the fixing difficulty of the battery assembly 3000.

[0098] In some embodiments, the first elastic piece is a spring, one end of the spring is arranged on the support 100, and the other end abuts against the moving clamping piece to achieve the driving of the moving clamping piece to move in the first direction towards the battery assembly 3000 by using the first elastic piece, ensuring the clamping and cooperation effect of the clamping assembly 200 and the battery assembly 3000, and further improving the position stability of the battery assembly 3000.

[0099] Of course, in other embodiments, the first elastic piece can also be a rubber piece, a silica gel piece, etc.

[0100] In some embodiments, as shown in FIGS. 7 and 8, the fixing module 1000 further comprises a mounting base 510 and a guide cylinder 520, the mounting base 510 is arranged on the support 100, the guide cylinder 520 is connected to the mounting base 510, and the first elastic member is arranged in the guide cylinder 520 and connected with the moving clamping member, so as to drive the moving clamping member to move towards the battery assembly 3000 in the first direction by the first elastic member.

[0101] In some embodiments, the mounting base 510 is connected to the support 100 by bolts.

[0102] In some embodiments, the first elastic member comprises a plurality of first elastic members, and the plurality of first elastic members are arranged in the second direction. In this way, the moving clamping member can be driven to move towards the battery assembly 3000 in the first direction by the plurality of first elastic members, so that the first elastic member can effectively drive the moving clamping member to move, facilitating the clamping assembly 200 to clamp the battery assembly 3000 and ensuring the clamping effect to a certain extent.

[0103] In some examples, after the driving assembly 400 drives the moving clamping member to move in the first direction, the driving assembly 400 no longer provides driving force, and at this time the moving clamping member is driven by the first elastic member, so that the moving clamping member has a moving trend towards the battery assembly 3000, and thus the matching protrusion 320 can be fixedly matched in the matching groove 310, achieving the purpose of fixing the battery assembly 3000.

[0104] In some embodiments, as shown in FIGS. 7 and 8, the fixing module 1000 further comprises a first guide member 600 arranged between the moving clamping member and the support 100, and the first guide member 600 is used to guide the moving clamping member to move in the first direction. This can not only reduce the difficulty of moving the moving clamping member in the first direction, but also improve the accuracy of moving the moving clamping member in the first direction, to a certain extent, avoiding the moving clamping member from deviating during movement, so that the matching protrusion 320 can be effectively fixedly matched in the matching groove 310, that is, the moving clamping member can effectively contact the battery assembly 3000 to fix the battery assembly 3000, reducing the difficulty of fixing the battery assembly 3000.

[0105] In some embodiments, as shown in FIG. 8, the first guide member 600 comprises a first guide protrusion 610 extending in the first direction and a first guide groove 620, the first guide protrusion 610 movably fits in the first guide groove 620, one of the first guide protrusion 610 and the first guide groove 620 is arranged on the moving clamping member, and the other is arranged on the support 100. Here, it is referred to that the first guide member 600 comprises the first guide protrusion 610 extending in the first direction and movably fitting in the first guide groove 620, so that when one of the first guide protrusion 610 and the first guide groove 620 is arranged on the moving clamping member and the other is arranged on the support 100, the movable fitting of the moving clamping member and the support 100 can be realized by using the first guide member 600, so as to guide the movement of the moving clamping member relative to the support 100 by using the first guide member 600, reduce the difficulty of the movement of the moving clamping member in the first direction, and improve the accuracy of the movement of the moving clamping member.

[0106] In some embodiments, as shown in FIG. 8, the first guide protrusion 610 is arranged on the support 100, the first guide groove 620 is arranged on the moving clamping member, and the first guide protrusion 610 movably fits in the first guide groove 620 to realize the movable fitting of the moving clamping member and the support 100.

[0107] Of course, in other embodiments, the first guide protrusion 610 can also be arranged on the moving clamping member, and the first guide groove 620 is arranged on the support 100, so that the movable fitting of the moving clamping member and the support 100 can also be realized by movably fitting the first guide protrusion 610 in the first guide groove 620.

[0108] It should be noted that when the first guide protrusion 610 is arranged on the support 100, the first guide protrusion 610 can be welded or bonded on the support 100 to improve the connection strength of the first guide protrusion 610 and the support 100, and to ensure the working performance of the first guide protrusion 610 to a certain extent.

[0109] In some embodiments, the first guide member 600 comprises a plurality of first guide members 600, and the plurality of first guide members 600 are arranged at intervals in the second direction, and the plurality of first guide members 600 can effectively guide the movement of the moving clamping member in the first direction, and further improve the accuracy of the movement of the moving clamping member in the first direction.

[0110] In some embodiments, as shown in FIGS. 2, 4 and 5, the fixing module 1000 further comprises a limiting member 700 for limiting the relative moving range of the first guiding protrusion 610 and the first guiding groove 620 in the first direction. To some extent, the first guiding protrusion 610 and the first guiding groove 620 are prevented from disengaging, so that the first guiding member 600 can effectively guide the moving clamping member to move in the first direction, and the accuracy of the moving clamping member moving in the first direction is improved.

[0111] In some embodiments, as shown in FIGS. 5, 7 and 8, the limiting member 700 comprises at least two limiting protrusions, which are arranged on the support member 100 and located on opposite sides of the moving clamping member in the first direction. In the first direction, the limiting protrusions face at least part of the moving clamping member, and the limiting protrusions can be in abutting engagement with the moving clamping member when the moving clamping member moves in the first direction, so as to limit the moving range of the moving clamping member relative to the support member 100 in the first direction. Since one of the first guiding protrusion 610 and the first guiding groove 620 is arranged on the moving clamping member, and the other is arranged on the support member 100, the relative moving range of the first guiding protrusion 610 and the first guiding groove 620 in the first direction can be limited by the limiting member 700, the first guiding protrusion 610 and the first guiding groove 620 are prevented from disengaging, and the accuracy of the moving clamping member moving in the first direction is improved.

[0112] In some embodiments, the first guiding protrusion 610 is arranged on the support member 100, the first guiding groove 620 is arranged on the moving clamping member, and the at least two limiting protrusions are arranged on opposite ends of the first guiding protrusion 610 in the first direction. The first guiding groove 620 is in moving engagement between the two limiting protrusions, and the two limiting protrusions face part of the moving clamping member arranged on the moving clamping member. In this way, during the movement of the moving clamping member, the moving distance of the moving clamping member in the first direction can be limited by the engagement of the two limiting protrusions, so as to limit the relative moving range of the first guiding protrusion 610 and the first guiding groove 620 in the first direction.

[0113] It should be noted that, as shown in FIGS. 5, 7 and 8, when the mounting base 510 is arranged on the support member 100 and the mounting base 510 is arranged on the side of the moving clamping member away from the battery assembly 3000, the mounting base 510 can serve as one of the limiting protrusions. At this time, only one limiting protrusion needs to be arranged on the end of the first guiding protrusion 610 facing the battery assembly 3000, which saves the arrangement of one limiting protrusion, is conducive to simplifying the structure of the first guiding protrusion 610, reducing the manufacturing difficulty of the first guiding protrusion 610, and also reducing the engagement difficulty of the first guiding protrusion 610 and the first guiding groove 620.

[0114] In some examples, a limiting protrusion is arranged at one end of the first guide protrusion 610, and during the assembly of the moving clamp, the first guide protrusion 610 is first moved and fitted into the first guide groove 620 through the other end of the first guide protrusion 610, at which time the moving clamp is installed on the support 100, and then the mounting base 510 and the guide cylinder 520 are installed, and the first elastic member in the guide cylinder 520 is in abutting fit with the moving clamp, so as to realize the movable connection of the moving clamp and the support 100.

[0115] In some embodiments, as shown in FIGS. 1, 2 and 6, the support 100 is provided with a second guide 110 extending in a second direction, and the second guide 110 is adapted to move and fit with the battery assembly 3000 to guide the battery assembly 3000 to move in the second direction, which is the extension direction of the first direction and the second direction. That is, the extension direction of the second guide 110 is different from the moving direction of the moving clamp, which to some extent avoids the interference between the battery assembly 3000 and the moving clamp during installation, is beneficial to fixing the battery assembly 3000 by the moving clamp, and reduces the difficulty of fixing and dismounting the battery assembly 3000.

[0116] Here, the second direction can be understood as the X direction shown in FIG. 2, that is, the moving clamp moves in the Y direction, and the second guide 110 extends in the X direction, and the second guide 110 is used to move and fit with the battery assembly 3000 to guide the battery assembly 3000 to move in the X direction, so as to realize the installation of the battery assembly 3000 on the support 100 in the X direction.

[0117] Meanwhile, the second guide 110 can also reduce the installation difficulty of the battery assembly 3000 and improve the positional accuracy of the battery assembly 3000 when moving in the X direction, so that the battery assembly 3000 can be accurately arranged on the support 100.

[0118] It should be noted that by accurately arranging the battery assembly 3000 on the support 100, on the one hand, the matching protrusion 320 can be fixedly fitted in the matching groove 310 to realize the clamping fit of the clamping assembly 200 and the battery assembly 3000, thereby facilitating the clamping and fixing of the battery assembly 3000 by the clamping assembly 200, and improving the positional stability of the battery assembly 3000, and on the other hand, the electric lead-out member 3200 on the battery assembly 3000 can form an electrical connection with the electrical connector 800, thereby reducing the electrical connection difficulty of the battery assembly 3000 and the electrical connector 800.

[0119] The specific structure of the electric lead-out member 3200 and the electrical connector 800 can be referred to below.

[0120] In addition, by arranging the second guide 110 on the support 100, the support 100 can also support the second guide 110, and the position stability of the second guide 110 is improved, and the working performance of the second guide 110 is ensured to a certain extent.

[0121] In some embodiments, the second guide 110 is arranged between the support 100 and the battery assembly 3000. The second guide 110 is used to guide the movement of the battery assembly 3000 in the second direction, and the accuracy of the movement of the battery assembly 3000 during installation is improved, so that the battery assembly 3000 can be accurately arranged on the support 100.

[0122] In some embodiments, as shown in FIG. 6, the second guide 110 is arranged between the two adjacent clamping members 210 arranged in the first direction. Since the battery assembly 3000 is arranged between the two adjacent clamping members 210 arranged in the first direction, the second guide 110 can be arranged opposite to the battery assembly 3000 by arranging the second guide 110 between the two adjacent clamping members 210 arranged in the first direction, so as to realize the movement cooperation between the second guide 110 and the battery assembly 3000, thereby facilitating the movement of the battery assembly 3000 in the second direction by using the second guide 110, improving the accuracy of the movement of the battery assembly 3000 during installation, and reducing the installation difficulty of the battery assembly 3000.

[0123] Through the above arrangement, during the installation of the battery assembly 3000, the battery assembly 3000 can be first arranged on the support 100 and moved along the extension direction of the second guide 110, and after the battery assembly 3000 is moved to the position, the driving assembly 400 is used to drive the moving clamping member to move in the first direction, so that the plurality of clamping members 210 can be in contact with the battery assembly 3000, so as to realize the fixation of the battery assembly 3000; when the battery assembly 3000 needs to be disassembled, the driving assembly 400 is first used to drive the moving clamping member to move in the first direction, so that the moving clamping member is separated from the battery assembly 3000, and then the battery assembly 3000 is moved along the extension direction of the second guide 110, so as to disassemble the battery assembly 3000.

[0124] In some embodiments, as shown in FIGS. 2, 6 and 7, the support 100 is provided with a plurality of second guides 110, and the plurality of second guides 110 are arranged in the first direction. In this way, the plurality of second guides 110 can be used to guide the movement of the battery assembly 3000 in the second direction, and the position accuracy of the battery assembly 3000 during installation is further ensured, so that the battery assembly 3000 can be accurately installed on the support 100.

[0125] In some embodiments, as shown in FIGS. 9, 10 and 11, the second guide 110 is a second guide protrusion provided on the support 100. The second guide protrusion facilitates the movement cooperation between the second guide 110 and the battery assembly 3000, and reduces the difficulty of cooperation between the second guide 110 and the battery assembly 3000.

[0126] In some embodiments, as shown in FIGS. 9, 10 and 11, the battery assembly 3000 is provided with a second guide groove 3100 extending in the second direction, and the second guide protrusion is movably arranged in the second guide groove 3100, so as to realize the movement cooperation between the second guide 110 and the battery assembly 3000.

[0127] Of course, in other embodiments, the second guide 110 can also be a second guide groove 3100 provided on the support 100, and the battery assembly 3000 is provided with a second guide protrusion movably arranged in the second guide groove 3100, so as to realize the movement cooperation between the second guide 110 and the battery assembly 3000.

[0128] It should be noted that when the second guide 110 is a second guide protrusion provided on the support 100, the second guide protrusion can be arranged on the support 100 by welding, bonding, bolt connection or integral molding, and the present application does not make specific limitation.

[0129] In some embodiments, as shown in FIGS. 2, 6 and 7, the fixed module 1000 further comprises an electrical connector 800, which is arranged on the support 100 and is arranged opposite to the second guide 110 in the second direction. The battery assembly 3000 is provided with an electrical lead-out 3200 (the specific structure of the electrical lead-out 3200 can be seen from FIG. 2), and the electrical connector 800 is adapted to be electrically connected with the electrical lead-out 3200. The above can also be understood as that the electrical connector 800 and the second guide 110 are arranged in sequence in the second direction, so that when the battery assembly 3000 is installed in place through the second guide 110, the electrical connection between the electrical connector 800 and the electrical lead-out 3200 is facilitated, thereby realizing the electrical connection between the electrical connector 800 and the battery assembly 3000, and reducing the difficulty of electrical connection between the electrical connector 800 and the battery assembly 3000.

[0130] The electrical connection between the electrical connector 800 and the battery assembly 3000 facilitates the transmission of electrical energy in the battery assembly 3000 to each electrical component of the electrical device 2000 by the electrical connector 800, and ensures the normal operation of the electrical device 2000.

[0131] In some embodiments, the electric connector 800 is a plug-in connector, and the plug-in connector is arranged opposite to the second guide 110 in the second direction, so that when the battery assembly 3000 is moved along the extending direction of the second guide 110, the electric connection between the electric connector 800 and the electric lead 3200 can be achieved when the battery assembly 3000 is moved into position, and the difficulty of electric connection between the electric connector 800 and the battery assembly 3000 is further reduced.

[0132] In some embodiments, the end ball of the electric lead 3200 is arranged, and the electric connector 800 is provided with a socket, and the socket is arranged with a rounded corner, so as to facilitate the electric connection between the electric connector 800 and the electric lead 3200, and reduce the difficulty of electric connection between the electric connector 800 and the battery assembly 3000, and the electric lead 3200 and the electric connector 800 can also play a role in assembly fixation when connected.

[0133] It should be noted that the electric lead 3200 is shown as two in FIG. 2, and the two electric leads 3200 are respectively the positive and negative electric leads of the battery assembly 3000.

[0134] In some embodiments, as shown in FIGS. 2, 6 and 7, the fixing module 1000 further comprises a second elastic member 900, and in the second direction, the second elastic member 900 is arranged opposite to the second guide 110 and close to the electric connector 800, and the second elastic member 900 is adapted to apply an action force to the battery assembly 3000 in a direction away from the electric connector 800. The above can also be understood as, in the second direction, the second elastic member 900 and the second guide 110 are arranged in sequence, and the second elastic member 900 is arranged at one end of the second guide 110 close to the electric connector 800, so that when the clamping assembly 200 is switched to the separated state to separate the moving clamping member from the battery assembly 3000, the second elastic member 900 is used to drive the battery assembly 3000 to move in a direction away from the electric connector 800, so as to facilitate the disassembly of the battery assembly 3000, and further reduce the difficulty of disassembly of the battery assembly 3000.

[0135] In some embodiments, as shown in FIGS. 2, 6 and 7, the electric connector 800 is arranged opposite to the second guide 110 in the second direction, and the second elastic member 900 is arranged at one end of the second guide 110 close to the electric connector 800 and opposite to the electric connector 800 in the first direction, so as to realize the arrangement of the second elastic member 900 and the second guide 110 in sequence and the arrangement of the second elastic member 900 close to the electric connector 800, which is conducive to ensuring that when the clamping assembly 200 is switched to the separated state to separate the moving clamping member from the battery assembly 3000, the second elastic member 900 can drive the battery assembly 3000 to move in a direction away from the electric connector 800, so as to reduce the difficulty of disassembly of the battery assembly 3000.

[0136] In some embodiments, the second elastic member 900 is a spring, and the spring is located at the same end of the second guide 110 as the electrical connector 800 in the second direction. When the battery assembly 3000 is installed in place on the support 100 so that the electrical lead-out 3200 on the battery assembly 3000 is electrically connected with the electrical connector 800, the battery assembly 3000 is used to press the spring so that the spring is charged. When the clamping assembly 200 is switched to the separation state so that the moving clamping member is separated from the battery assembly 3000, the second elastic member 900 is used to drive the battery assembly 3000 to move away from the electrical connector 800.

[0137] Of course, in other embodiments, the second elastic member 900 can also be a rubber member, a silica gel member, etc.

[0138] Through the above arrangement, during the installation of the battery assembly 3000, the battery assembly 3000 can be first arranged on the support 100 and the second guide 110 on the support 100 is matched with the battery assembly 3000. Then the battery assembly 3000 is moved along the extension direction of the second guide 110 so that the electrical lead-out 3200 on the battery assembly 3000 is electrically connected with the electrical connector 800, and the battery assembly 3000 presses the second elastic member 900. Finally, the moving clamping member is driven to move in the first direction by the driving assembly 400, so that the plurality of clamping members 210 can be in contact with the battery assembly 3000 to achieve the fixation of the battery assembly 3000. When the battery assembly 3000 needs to be disassembled, the moving clamping member is first driven to move in the first direction by the driving assembly 400, and the moving clamping member is separated from the battery assembly 3000.
