[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0034] The following is for reference. Figures 1-3 A pole mounting device and a battery according to an embodiment of the invention are described.
[0035] like Figures 1-3 As shown, the pole mounting device of this embodiment includes a mounting component 1 and a pole body 2.
[0036] Mounting component 1 includes connecting parts 11 and snap-fit members 12. There are at least two connecting parts 11, and at least two connecting parts 11 are positioned in a first direction (e.g., ...). Figure 1 The components are arranged at intervals in the front-to-back direction (as shown) to form an installation space between adjacent connecting parts 11. At least one of the adjacent connecting parts 11 is provided with a snap-fit member 12, which is movable relative to the corresponding connecting part 11 in a first direction. At least a portion of the mounting assembly 1 is energized. The pole body 2 has a snap-fit part 21, at least a portion of which can be inserted into the installation space. The snap-fit part 21 abuts against the snap-fit member 12 on one side in the direction of exiting the installation space.
[0037] like Figures 1-3 As shown, the mounting assembly 1 includes two connecting portions 11 spaced apart in the front-to-back direction, forming an installation space between the two connecting portions 11 for inserting the pole body 2. The pole body 2 is preferably inserted into the installation space in a top-to-bottom direction. At least one of the two connecting portions 11 is provided with a snap-fit member 12. The snap-fit member 12 is movable in the front-to-back direction relative to the connecting portion 11 on which it is provided, so that at least a portion of the snap-fit member 12 can extend into and exit the installation space. The front end and / or rear end of the pole body 2 is provided with a snap-fit portion 21, and the snap-fit portion 21 is provided in a one-to-one correspondence with the snap-fit member 12.
[0038] During the process of inserting the whole or lower end of the pole body 2 into the installation space, at least part of the clamping member 12 is withdrawn from the installation space to avoid the clamping portion 21, so that the whole or lower end of the pole body 2 can be inserted into the installation space. After the whole or lower end of the pole body 2 is inserted into the installation space, at least part of the clamping member 12 extends into the installation space and is located above the clamping portion 21. At this time, the clamping member 12 abuts against the clamping portion 21 to prevent the pole body 2 from moving upward, thereby avoiding the pole body 2 from being separated from the installation assembly 1.
[0039] At least part of the installation assembly 1 is electrically conductive. When the whole or lower end of the pole body 2 is inserted into the installation space, the pole body 2 is connected with at least part of the installation assembly 1, so that at least part of the installation assembly 1 can realize the function of current confluence.
[0040] Since the pole body 2 in the embodiment is preferably inserted into the installation space in the direction from top to bottom, the direction of entering the installation space in the embodiment is the downward direction, and the direction of withdrawing from the installation space is the upward direction.
[0041] The pole body of the pole installation device in the embodiment can be inserted into the installation space of the installation assembly, so that the installation assembly is connected with the pole body, and the clamping member abuts against the clamping portion to prevent the pole body and the installation assembly from being separated. Therefore, the electrically conductive installation assembly is connected with the pole body by clamping, and the connection process of the installation assembly and the pole body is simple, and the assembly efficiency is high. Compared with the related art, the welding equipment is not required, and the production and processing cost is reduced.
[0042] In some embodiments, the installation assembly 1 further comprises a first elastic member 13, the connecting portion 11 has a receiving cavity 111 extending in the first direction, at least part of the clamping member 12 can extend into and withdraw from the receiving cavity 111, the first elastic member 13 is arranged in the receiving cavity 111, and the first elastic member 13 is connected between the connecting portion 11 and the clamping member 12 to drive at least part of the clamping member 12 to extend out of the receiving cavity 111.
[0043] As shown in FIG. 1, Figure 2 As shown in FIG. 1,
[0044] The front end face of the connecting part 11 forming the mounting space is provided with a recess to form a receiving cavity 111, and the clamping part 12 can slide in the receiving cavity 111 in the front-rear direction and has a stop position and an avoiding position. In the stop position, the front end of the clamping part 12 extends out of the receiving cavity 111 and is located in the mounting space to stop the clamping part 21. In the avoiding position, the clamping part 12 can be completely withdrawn into the receiving cavity 111 according to the size of the clamping part 21, or a part of the clamping part 12 can be left in the mounting space. The clamping part 12 can avoid the downwardly moving clamping part 21 in the avoiding position, so that the entire or lower end of the pole body 2 can be inserted into the mounting space.
[0045] The first elastic part 13 can be a rubber part or a spring. Preferably, the first elastic part 13 is a spring extending in the front-rear direction. The first elastic part 13 is located in the receiving cavity 111, the rear end of the first elastic part 13 is connected to the rear end face of the receiving cavity 111, and the front end of the first elastic part 13 is connected to the rear end of the clamping part 12 to drive the clamping part 12 to move from the avoiding position to the stop position. After the entire or lower end of the pole body 2 is inserted into the mounting space, the clamping part 12 is automatically moved to the stop position under the driving of the first elastic part 13 to stop the clamping part 21.
[0046] It can be understood that the mounting structure of the clamping part is not limited to the structure as shown in Figure 2 In other embodiments, the top end of the clamping part is hinged to the connecting part, so that the clamping part can rotate relative to the connecting part in the left-right direction. In other words, the clamping part rotates between the stop position and the avoiding position.
[0047] It can be understood that the mounting assembly is not limited to having the first elastic part. In other embodiments, the upper end face of the connecting part is provided with a channel, the channel is in communication with the receiving cavity, and the channel is a strip-shaped extending in the front-rear direction. The top of the clamping part is provided with an operating rod, the top end of the operating rod extends out of the connecting part through the channel, and the clamping part is driven to move between the stop position and the avoiding position by pushing the operating rod.
[0048] It can be understood that the structure of the clamping part is not limited to the protruding part on the pole body. In other embodiments, the front end face and / or rear end face of the pole body is provided with a clamping groove, and the clamping part is used to clamp in the clamping groove. At this time, the end face of the clamping groove stopping the clamping part is the clamping part.
[0049] In some embodiments, the clamping portion 21 has a first inclined surface 211 at one end of the clamping portion 21 in the direction of insertion into the installation space, the first inclined surface 211 extends in a direction away from the center line of the pole body 2 and is arranged obliquely in the direction of exit from the installation space; and / or the clamping member 12 has a second inclined surface 121 at one end of the clamping member 12 in the direction of exit from the installation space, the second inclined surface 121 extends in a direction away from the first elastic member 13 and is arranged obliquely in the direction of insertion into the installation space.
[0050] As shown in Figure 2 , the lower end surface of the clamping portion 21 is the first inclined surface 211, which extends in the direction from front to back and is arranged obliquely upward, and the upper end surface of the front end of the clamping member 12 is the second inclined surface 121, which extends in the direction from back to front and is arranged obliquely downward, preferably, the first inclined surface 211 and the second inclined surface 121 are arranged in parallel.
[0051] When the pole body 2 is inserted into the installation space, the clamping portion 21 is first located above the clamping member 12 and moves from top to bottom, then the first inclined surface 211 and the second inclined surface 121 abut, the first inclined surface 211 generates a backward pushing force on the second inclined surface 121, so that the clamping member 12 overcomes the elastic force of the first elastic member 13 and moves from the abutting position to the avoiding position, so that the clamping portion 21 can continue to move downward and move below the clamping member 12, when the pushing force of the first inclined surface 211 on the second inclined surface 121 disappears, the clamping member 12 moves to the abutting position under the drive of the first elastic member 13 and abuts above the clamping portion 21. Therefore, under the cooperation of the first inclined surface 211 and the second inclined surface 121, the clamping member 12 can automatically avoid the clamping portion 21 during the insertion of the pole body 2 into the installation space.
[0052] It can be understood that the structure of the clamping portion and the clamping member is not limited to the structure as Figure 2 described, in other embodiments, the clamping portion has a first inclined surface, but the clamping member does not have a second inclined surface, during the downward movement of the clamping portion, the edge line connecting the upper end surface and the front end surface of the clamping member abuts the first inclined surface, so that the first inclined surface drives the clamping member to move to the avoiding position. Or the clamping member has a second inclined surface, but the clamping portion does not have a first inclined surface, during the downward movement of the clamping portion, the edge line connecting the lower end surface and the rear end surface of the clamping member abuts the second inclined surface, so that the clamping member moves to the avoiding position. Or, the clamping portion does not have a first inclined surface, and the clamping member does not have a second inclined surface, the clamping member is driven to move between the abutting position and the avoiding position by the pushing operation rod.
[0053] In some embodiments, the snap-fit portion 21 has a first abutting surface 212 extending along a first direction and located at one end of the snap-fit portion 21 in the direction of exiting the mounting space. The snap-fit member 12 has a second abutting surface 122 and a third abutting surface 123, both extending along the first direction. The second abutting surface 122 is located at one end of the snap-fit member 12 in the direction of exiting the mounting space and abuts against the connecting portion 11. The third abutting surface 123 is located at one end of the snap-fit member 12 in the direction of entering the mounting space and serves to abut against the first abutting surface 212.
[0054] like Figure 2 As shown, the upper surface of the latching portion 21 is a first abutting surface 212, which is a horizontal surface extending in the front-rear direction. The upper surface of the rear end of the latching member 12 is a second abutting surface 122. In other words, the upper surface of the latching member 12 includes a second inclined surface 121 and a second abutting surface 122, with the second inclined surface 121 located in front of the second abutting surface 122. The second abutting surface 122 is a horizontal surface extending in the front-rear direction, and during the movement of the latching member 12 in the front-rear direction, the second abutting surface 122 always abuts against the upper surface of the receiving cavity 111. The lower surface of the latching member 12 is a third abutting surface 123, which is a horizontal surface extending in the front-rear direction, and at least a portion of the third abutting surface 123 abuts against the lower surface of the receiving cavity 111.
[0055] After the entire or lower end of the pole body 2 is inserted into the installation space, the front end of the snap-fit 12 is positioned above the snap-fit portion 21, and the third abutting surface 123 abuts against the first abutting surface 212 to prevent the snap-fit portion 21 from moving upward, thereby preventing the pole body 2 from detaching from the installation space and separating from the installation assembly 1. At the same time, since the second abutting surface 122 abuts against the upper end surface of the receiving cavity 111, and at least a portion of the third abutting surface 123 abuts against the lower end surface of the receiving cavity 111, the snap-fit 12 will not wobble relative to the connecting portion 11, and the pole body 2, abutted by the snap-fit 12, will not wobble relative to the connecting portion 11 and the installation assembly 1, thus ensuring a stable connection of the pole body 2 and enabling the pole body 2 to stably merge current.
[0056] Understandably, the structure of the snap-fit part and snap-fit component is not limited to, for example... Figure 2 In some embodiments of the structure, the upper end face of the snap-fit portion and the lower end face of the snap-fit member also have mutually cooperating inclined surfaces. When an upward pulling force is applied to the pole body, the snap-fit member moves from the stop position to the avoidance position. At this time, the pole body can be detached from the mounting assembly for replacement. However, in order to ensure the connection stability of the pole body, the first elastic member needs to have a large elastic force so that the pole body can only be pushed out of the mounting space when subjected to a large pulling force.
[0057] In some embodiments, the mounting assembly 1 further comprises a second elastic member 14 arranged in a direction in which the pole body 2 exits the mounting space, and the second elastic member 14 is arranged to abut against the pole body 2 or the battery body 5 provided with the pole body 2 to push the clamping portion 21 to abut against the clamping member 12 in the direction in which the pole body 2 exits the mounting space.
[0058] As shown in Figure 1 , the mounting assembly 1 further comprises a second elastic member 14 arranged in the up-down direction, and the top end of the second elastic member 14 abuts against the pole body 2 or the battery body 5 provided with the pole body 2 after the entire or lower end of the pole body 2 is inserted into the mounting space, so as to apply an upward pushing force to the pole body 2 to ensure that the third abutting surface 123 abuts against the first abutting surface 212, thereby defining the position of the pole body 2 in the up-down direction by the second elastic member 14 and the clamping member 12, avoiding the up-down movement of the pole body 2 below the clamping member 12, stabilizing the connection of the pole body 2, and enabling the pole body 2 to be stably converged. Meanwhile, the second elastic member 14 can also serve as a buffer for the pole body 2, on the one hand, avoiding damage to the clamping member and the clamping portion when the pole mounting device is subjected to a large impact force, and on the other hand, in the process of inserting the pole body into the mounting space, the second elastic member is compressed by the pressure transmitted by the pole body, so that the pole body has a certain installation gap, facilitating the rapid assembly of the pole body. Preferably, the second elastic member 14 is a spring.
[0059] It can be understood that the mounting assembly is not limited to having the second elastic member, and in other embodiments, the distance between the upper end surface of the clamping portion and the lower end surface of the pole body is consistent with the distance between the lower end surface of the clamping member and the bottom surface of the mounting space, and in this case, the second elastic member can not be arranged.
[0060] In some embodiments, the connecting portion 11 extends in a second direction (e.g., the left-right direction as shown in Figure 1 ), the second direction is orthogonal to the first direction, the clamping member 12 on the same connecting portion 11 is a plurality of clamping members 12, and the plurality of clamping members 12 are arranged in the second direction, and each clamping member 12 is arranged to abut against the clamping portion 21 of the corresponding pole body 2.
[0061] As shown in Figure 1As shown, the connecting portion 11 is a strip extending along the left-right direction, and the clamping pieces 12 on the same connecting portion 11 are multiple, and the multiple clamping pieces 12 are arranged in the left-right direction at intervals, and each clamping piece 12 is used for abutting against the clamping portion 21 of the corresponding pole body 2, in other words, the mounting space formed by the adjacent two connecting portions 11 can simultaneously insert multiple pole bodies 2, and the multiple pole bodies 2 are sequentially arranged in the left-right direction, and the clamping portion 21 of each pole body 2 is respectively abutted by the corresponding clamping piece 12, so that the mounting assembly 1 can simultaneously assemble multiple pole bodies 2, and the part of the mounting assembly 1 that can be electrified is connected with each pole body 2 to play a role of converging.
[0062] It can be understood that the connecting portion is not limited to a strip extending along the left-right direction, and in other embodiments, the connecting portion is rectangular, and the multiple connecting portions on the mounting assembly are arranged in the left-right direction at intervals, in other words, the first direction is the left-right direction, and the multiple mounting spaces formed by the multiple connecting portions are arranged in the left-right direction at intervals, and the corresponding pole body is inserted in each mounting space, and the clamping piece is movable relative to the connecting portion arranged thereon in the left-right direction.
[0063] In some embodiments, the pole body 2 has the clamping portion 21 at both ends arranged in the first direction, the adjacent two connecting portions 11 are respectively provided with the clamping piece 12, and the clamping piece 12 on one of the connecting portions 11 is arranged opposite to the clamping piece 12 on the other connecting portion 11 in the first direction.
[0064] As shown in Figure 1 and Figure 3 , the pole body 2 has a rectangular cross section, the front end face of the pole body 2 is provided with one clamping portion 21, the rear end face of the pole body 2 is provided with another clamping portion 21, and the two strip-shaped connecting portions 11 in the mounting assembly 1 are provided with multiple clamping pieces 12, wherein the rear end face of the connecting portion 11 located on the front side is provided with multiple clamping pieces 12, the front end face of the connecting portion 11 located on the rear side is provided with multiple clamping pieces 12, the multiple clamping pieces 12 on the connecting portion 11 located on the front side are arranged one by one corresponding to the multiple clamping pieces 12 on the connecting portion 11 located on the rear side, one clamping portion 21 of the pole body 2 abuts against the clamping piece 12 on the connecting portion 11 located on the front side, and the other clamping portion 21 of the pole body 2 abuts against the clamping piece 12 on the connecting portion 11 located on the rear side, so that the pole body 2 is stably installed.
[0065] It can be understood that the pole body is not limited to having the clamping portions at both front and rear ends, and in some embodiments, the connecting portion on the front side does not have the clamping piece, and the front end face of the pole body does not have the clamping portion, the rear end face of the connecting portion on the front side abuts against the front end face of the pole body, and the clamping portion on the rear end face of the pole body is connected by clamping the clamping piece on the connecting portion on the rear side.
[0066] In some embodiments, the mounting component 1 further includes a base 15 and a bus.
[0067] The base 15 has a boss forming a connecting portion 11, and a second elastic member 14 is provided on the base 15. The busbar extends along a second direction and is provided on the base 15. When at least a portion of the pole body 2 is inserted into the installation space, the busbar abuts against the pole body 2, or the busbar and the pole body 2 are electrically connected through the second elastic member 14.
[0068] like Figure 1 As shown, the base 15 is a plate extending in the left-right direction. The front end of the base 15 has a strip-shaped protrusion extending in the left-right direction to form the front connecting part 11. The rear end of the base 15 has another strip-shaped protrusion extending in the left-right direction to form the rear connecting part 11. A groove between the two strip-shaped protrusions forms an installation space. A busbar is embedded on the bottom surface of the groove, and the busbar is a strip extending in the left-right direction. The second elastic element 14 is preferably a metal spring. The second elastic element 14 is located within the installation space, and its lower end is connected to the busbar. When the pole body 2 is inserted into the installation space, the lower end face of the pole body 2 abuts against the upper end of the second elastic element 14, so that the pole body 2 and the busbar are electrically connected through the second elastic element 14. The two connecting parts 11 serve to position the second elastic element 14.
[0069] It is understood that the busbar and the terminal block are not limited to being electrically connected via a second elastic element. In other embodiments, the terminal block and the busbar abut against each other when the terminal block is inserted into the installation space.
[0070] It is understood that the second elastic member is not limited to being located within the installation space. In other embodiments, the second elastic member is located on the boss forming the connection portion, and the upper end of the second elastic member abuts against the cell body having the electrode post body.
[0071] It is understandable that the structure of the base and connecting parts is not limited to that shown below. Figure 1 In some embodiments of the structure shown, the base is a frame and the connecting part is a bracket provided on the frame.
[0072] It is understood that the pole body is not limited to being inserted into the installation space in a top-to-bottom direction. In other embodiments, the opening formed at the left end of the base is the entrance to the installation space. Multiple pole bodies are inserted into the installation space sequentially from left to right. In this case, the direction of entering the installation space is to the right, and the direction of exiting the installation space is to the left. The snap-fit abuts on the left side of the snap-fit part of the corresponding pole body. During the assembly process, the pole body located at the rightmost end of the base needs to pass through all the multiple snap-fits from left to right.
