[0042] Embodiment

[0043] Refer to Figure 1 and Figure 2 , in this embodiment, a battery fixture is proposed, which includes a clamping device 100 and a driving device 200. Among them, there are multiple clamping devices 100 arranged side by side. For the convenience of observation, Figure 1 , Figure 2 , Figure 6 and Figure 11 only show two clamping devices 100.

[0044] The clamping device 100 includes a first clamping part 110, a second clamping part 120 and a receiving space 130. The receiving space 130 is located between the first clamping part 110 and the second clamping part 120. Among them, the receiving space 130 is used to receive the battery. Both the first clamping part 110 and the second clamping part 120 can adopt a plate-like structure, and the first clamping part 110 and the second clamping part 120 are arranged in parallel.

[0045] The driving device 200 is used to drive the first clamping part 110 and the second clamping part 120 of each clamping device 100 to move towards each other or away from each other, so as to synchronously adjust the width of each receiving space 130. In Figure 2 it, the width direction of the interval is parallel to the arrow x, and the height direction of the interval is parallel to the arrow y. In this embodiment, the arrow x is parallel to the width direction of the first clamping part 110 and the second clamping part 120, and the arrow y is parallel to the height direction of the first clamping part 110 and the second clamping part 120.

[0046] In this embodiment, only by the driving device 200 can the first clamping part 110 and the second clamping part 120 of each clamping device 100 be driven to move towards each other or away from each other, thereby synchronously adjusting the width of each receiving space 130, so that all the batteries can be clamped or loosened simultaneously, thereby improving the working efficiency of the battery fixture and facilitating the positioning of the battery.

[0047] Specifically, under the action of the driving device 200, the first clamping part 110 and the second clamping part 120 of the clamping device 100 can move towards each other synchronously or move away from each other synchronously. Among them, the first clamping part 110 and the second clamping part 120 moving towards each other synchronously means that the first clamping part 110 and the second clamping part 120 move towards each other's direction at the same speed; the first clamping part 110 and the second clamping part 120 moving away from each other synchronously means that the first clamping part 110 and the second clamping part 120 move away from each other's direction at the same speed.

[0048] Since the moving speeds are the same, the distances moved by the first clamping part 110 and the second clamping part 120 are the same whether they move towards each other or away from each other. For this reason, the geometric center distances of the first clamping part 110 and the second clamping part 120 from the receiving space 130 can remain unchanged.

[0049] Based on the above description, it can be seen that in this embodiment, since the first clamping portion 110 and the second clamping portion 120 of the clamping device 100 can move towards each other or away from each other under the action of the driving device 200, therefore, the operation of clamping or loosening the battery can be achieved only by the movement of the first clamping portion 110 and the second clamping portion 120. Among them, during this process, the battery located in the accommodation space 130 can keep its position unchanged, which facilitates the handling device to put the battery into or take out of the accommodation space 130.

[0050] The handling device places the battery in the accommodation space 130. At this time, the position where the battery is located is the first initial position, and the handling device is in the second initial position; subsequently, the driving device 200 drives the first clamping portion 110 and the second clamping portion 120 of the clamping device 100 to move towards each other, so that the battery is clamped by the first clamping portion 110 and the second clamping portion 120. During this process, the battery always remains in the first initial position, which enables the handling device to not need to adjust its position; after the battery is clamped, the handling device loosens the battery and moves to the set position; when the battery completes the corresponding operation (such as liquid injection, etc.), the handling device only needs to move back to the second initial position, without detecting the current position of the battery; after the handling device clamps the battery, the driving device 200 drives the first clamping portion 110 and the second clamping portion 120 of the clamping device 100 to move away from each other, so that the battery is loosened by the first clamping portion 110 and the second clamping portion 120. During this process, the battery still remains in the first initial position, which enables the handling device to not need to adjust its position. This effectively simplifies the control of the handling device and facilitates the positioning of the battery. Among them, when the handling device puts the battery into the accommodation space 130, it only needs to carry the battery to the first initial position.

[0051] The handling device may include a manipulator and the like.

[0052] As Figures 3 - 5 shown, the driving device 200 includes a linear motion module 210 and a mounting seat 220. The linear motion module 210 is used to drive the mounting seat 220 to perform a linear motion along a direction parallel to the preset direction. Among them, the preset direction is perpendicular to the width direction of the accommodation space 130. In this embodiment, the preset direction is parallel to the height direction of the accommodation space 130, that is, parallel to the arrow y.

[0053] The mounting seat 220 is provided with a first guiding structure 221 and a second guiding structure 222. For the convenience of processing and the like, the mounting seat 220 can be made of a plate.

[0054] One or more first clamping portions 110 are provided with first mating structures 111, and one or more second clamping portions 120 are provided with second mating structures 121. Among them, the first mating structure 111 corresponds to the first guiding structure 221, and the second mating structure 121 corresponds to the second guiding structure 222. Specifically, the first mating structure 111 and the first guiding structure 221 are in one-to-one correspondence, and the second mating structure 121 and the second guiding structure 222 are in one-to-one correspondence.

[0055] In this embodiment, only one first clamping portion 110 is provided with the first mating structure 111, and only one second clamping portion 120 is provided with the second mating structure 121, which can simplify the structure and reduce the manufacturing and assembly costs. In other embodiments, according to needs, the first mating structure 111 can be provided on multiple first clamping portions 110, and the second mating structure 121 can be provided on multiple second clamping portions 120.

[0056] In order to move all the first clamping portions 110 synchronously, all the first clamping portions 110 are fixedly connected. In this way, when one first clamping portion 110 moves, the other first clamping portions 110 will move accordingly; in order to move all the second clamping portions 120 synchronously, all the second clamping portions 120 are fixedly connected. In this way, when one second clamping portion 120 moves, the other second clamping portions will move accordingly.

[0057] The first clamping portion 110 and the second clamping portion 120 of the clamping device 100 are arranged in parallel. Among them, the first clamping portions 110 of each clamping device 100 are arranged in parallel, and the second clamping portions 120 of each clamping device 100 are arranged in parallel. It can be understood that all the first clamping portions 110 and the second clamping portions 120 are arranged in parallel. This can make the widths of different positions of the accommodation interval 130 change synchronously.

[0058] As Figure 6 shown, the battery fixture further includes a first connecting member 310 and a second connecting member 320. Among them, each first clamping portion 110 is fixedly connected to the first connecting member 310, and each second clamping portion 120 is fixedly connected to the second connecting member 320.

[0059] The first connecting member 310 and the second connecting member 320 are strip-shaped structures, which are convenient for installation and avoid occupying space. In order to ensure the connection strength, the first connecting member 310 and the second connecting member 320 can be made of materials with higher strength such as steel. Among them, the first connecting member 310 and the first clamping portion 110 can be fixedly connected by means of bolt connection, etc., and the second connecting member 320 and the second clamping portion 120 can be fixedly connected.

[0060] In this embodiment, the moving direction of the first clamping portion 110 is set as the first direction, and the moving direction of the second clamping portion 120 is set as the second direction. The first direction and the second direction are opposite to each other and are both parallel to the width direction of the accommodation interval 130. Refer to Figure 2 , regardless of whether the first clamping portion 110 moves horizontally to the left or horizontally to the right, the moving direction of the first clamping portion 110 is uniformly referred to as the first direction; regardless of whether the second clamping portion 120 moves horizontally to the left or horizontally to the right, the moving direction of the second clamping portion 120 is uniformly referred to as the second direction. The first direction and the second direction are both parallel to the arrow x.

[0061] Among them, the first guiding structure 221 is configured to guide the first mating structure 111 to move in the first direction, and the second guiding structure 222 is configured to guide the second mating structure 121 to move in the second direction. Since the first mating structure 111 is provided on the first clamping portion 110, when the first mating structure 111 moves in the first direction under the action of the first guiding structure 221, the first clamping portion 110 will move synchronously with the first mating structure 111; since the second mating structure 121 is provided on the second clamping portion 120, when the second mating structure 121 moves in the second direction under the action of the second guiding structure 222, the second clamping portion 120 will move synchronously with the second mating structure 121.

[0062] In this embodiment, the first guiding structure 221 includes a first guiding groove, and the second guiding structure 222 includes a second guiding groove. The first guiding groove corresponds to the second guiding groove, and the first guiding groove and the corresponding second guiding groove are symmetrically arranged with respect to a preset plane. The first mating structure 111 is slidably disposed in the first guiding groove, and the second mating structure 121 is slidably disposed in the second guiding groove.

[0063] Specifically, the first guiding grooves and the second guiding grooves correspond to each other one by one. Refer to Figure 2 and Figure 4 , the dashed line A represents the projection of the preset plane in this view angle.

[0064] Both the first guiding groove and the second guiding groove extend along a preset direction. From the head end to the tail end of the first guiding groove, the distance between the first guiding groove and the preset plane gradually increases or decreases. Since the second guiding groove is symmetrically arranged with the first guiding groove, the head end of the second guiding groove is symmetric with the head end of the first guiding groove, and the tail end of the second guiding groove is symmetric with the tail end of the first guiding groove. Correspondingly, from the head end to the tail end of the second guiding groove, the distance between the second guiding groove and the preset plane gradually increases or decreases.

[0065] Refer to Figure 4 , in this embodiment, the head end of the first guiding groove is located above the tail end, and among them, compared with the tail end, the head end is closer to the preset plane.

[0066] In the attachment Figure 4 , the first mating structure 111 is located at the head end of the first guiding groove, and the second mating structure 121 is located at the head end of the second guiding groove. At this time, the distance between the first mating structure 111 and the second mating structure 121 is the smallest. Correspondingly, the distance between the first clamping portion 110 and the second clamping portion 120 in the clamping device 100 is also the smallest. At this time, the width of the accommodation interval 130 is the smallest. When the linear motion module 210 drives the mounting seat 220 to move vertically downward, the first mating structure 111 moves in a direction away from the preset plane under the action of the first guiding groove, and the second mating structure 121 moves in a direction away from the preset plane under the action of the second guiding groove. During this process, the first mating structure 111 and the second mating structure 121 move synchronously, and the distance between the first mating structure 111 and the second mating structure 121 gradually increases. Among them, when the first mating structure 111 moves to the end of the first guiding groove and the second mating structure 121 moves to the end of the second guiding groove, the distance between the first mating structure 111 and the second mating structure 121 is the largest. Correspondingly, the distance between the first clamping portion 110 and the second clamping portion 120 in the clamping device 100 is also the largest. At this time, the width of the accommodation interval 130 is the largest.

[0067] In this embodiment, the cross-sections of the first mating structure 111 and the second mating structure 121 are both circular. Among them, the first mating structure 111 has a clearance fit with the first guiding groove, and the second mating structure 121 has a clearance fit with the second guiding groove. In this way, it can be ensured that the first mating structure 111 slides smoothly in the first guiding groove and the second mating structure 121 slides smoothly in the second guiding groove. Specifically, the first mating structure 111 and the second mating structure 121 can adopt a cylindrical structure, which is convenient for processing.

[0068] The first mating structure 111 can be fixedly connected to the corresponding first clamping portion 110 and the second mating structure 121 can be fixedly connected to the corresponding second clamping portion 120 by means of bolt connection or the like.

[0069] In this embodiment, the first guiding structure 221 includes a plurality of first guiding grooves arranged in sequence along a preset direction, and the second guiding structure 222 includes a plurality of second guiding grooves arranged in sequence along a preset direction, thereby ensuring the stability of guiding.

[0070] The linear motion module 210 includes a cylinder, a hydraulic cylinder, an electric push rod or a linear motion mechanism. The linear motion mechanism includes a crank-slider mechanism, a cam mechanism, a lead screw-nut mechanism, and so on.

[0071] Taking a cylinder as an example, the main body of the cylinder is fixed to the frame 400 of the battery fixture. The piston of the cylinder is connected to the connecting body 240. Among them, the connecting body 240 can be fixed to the mounting seat 220 by means such as bolt connection. When the piston of the cylinder moves, the connecting body 240 will move linearly under the action of the piston, thereby driving the mounting seat 220 to translate.

[0072] As Figure 1 and Figure 2 shown, a guiding device 230 can be provided on the mounting seat 220. The guiding device 230 can enable the mounting seat 220 to move smoothly along a direction parallel to the preset direction. The guiding device 230 includes a slider 231 and a guide rail 232. The slider 231 is slidably connected to the guide rail 232. Among them, the slider 231 is fixed to the mounting seat 220, and the guide rail 232 is fixed to the frame 400 of the battery fixture. A plurality of sliders 231 can be provided, thereby ensuring the stability of the mounting seat 220 during movement.

[0073] As Figure 7 and Figure 8 shown, the frame 400 of the battery fixture is located on the outermost side, playing a role of protection and decoration. The clamping device 100 is located inside the frame 400. Among them, for the convenience of installation, maintenance and repair, the linear motion module 210 is installed outside the frame 400. In order to protect the linear motion module 210, a protective cover 410 can be provided outside the linear motion module 210.

[0074] In this embodiment, two driving devices 200 can be provided and are symmetrically arranged. Among them, the two driving devices 200 are configured to act synchronously. By providing two driving devices 200, it can be ensured that the first clamping portion 110 and the second clamping portion 120 are more balanced in force, and the stability of the movement of the first clamping portion 110 and the second clamping portion 120 is ensured. Since two driving devices 200 are adopted, the power required for each driving device 200 will be reduced. Among them, compared with a single high-power driving device 200, the cost required for two lower-power driving devices 200 is lower.

[0075] As Figures 7 - 11 shown, in this embodiment, through holes 140 are provided on both the first clamping portion 110 and the second clamping portion 120. The through holes 140 are used for the mounting shaft 150 to pass through. Among them, all the through holes 140 are located on the same straight line.

[0076] The mounting shaft 150 is slidably connected to the through hole 140. Among them, the mounting shaft 150 is parallel to the width direction of the accommodation interval 130, and the slidable directions of the first clamping portion 110 and the second clamping portion 120 relative to the mounting shaft 150 are also parallel to the width direction of the accommodation interval 130. A flange 151 may be provided at the end of the mounting shaft 150. Among them, the flange 151 can be fixed to the frame 400 of the battery fixture by means such as bolt connection, thereby realizing the fixation of the mounting shaft 150.

[0077] The mounting shaft 150 has the functions of limiting and anti-fooling. Among them, through the cooperation of the mounting shaft 150 and the through hole 140, the first clamping portion 110 and the second clamping portion 120 can only move stably in the direction parallel to the width direction of the accommodation interval 130. Considering the stability of the connection and the symmetry of the structure, etc., the number of mounting shafts 150 is usually set to an even number. Refer to Figure 11 , in this embodiment, four mounting shafts 150 are provided. In other embodiments, the number of mounting shafts 150 can also be set as needed.

[0078] When it is necessary to clamp batteries of different models or sizes, the corresponding clamping device 100 needs to be adapted. At this time, the mounting shaft 150 can be removed, and after removing the first matching structure 111 and the second matching structure 121, the current clamping device 100 can be taken out from the opening at the top of the frame 400; subsequently, the adapted clamping device 100 is placed in from the opening at the top of the frame 400, and after installing the mounting shaft 150 and assembling the first matching structure 111 and the second matching structure 121, the installation of the adapted clamping device 100 can be completed.

[0079] Furthermore, a linear bearing 141 is provided in the through hole 140. Among them, the mounting shaft 150 is slidably inserted into the inner hole of the linear bearing 141.

[0080] As Figure 9 and Figure 10 shown, the first clamping portion 110 includes a first side surface 112, and the second clamping portion 120 includes a second side surface 122. The first side surface 112 and the second side surface 122 are arranged opposite to each other. Among them, the accommodation interval 130 is located between the first side surface 112 and the second side surface 122.

[0081] In this embodiment, clamping plates 160 for contacting the battery are provided on both the first side surface 112 and the second side surface 122. When clamping the battery, the clamping plates 160 are in direct contact with the battery.

[0082] The clamping plate 160 can be elastic. In this way, when clamping the battery, the clamping plate 160 can play a role in protecting the battery, thus avoiding the situation that the battery is damaged due to the extrusion of the first clamping portion 110 and the second clamping portion 120. The clamping plate 160 can be made of silica gel, rubber or other elastic materials.
