Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and particularly relates to a self-locking structure for a battery pack and a vehicle. Background Art

[0002] With the development and application of new energy technologies, electric vehicles, as a new type of energy vehicle, are increasingly popular among the public and are also taking up an increasing proportion in the vehicle market. Electric vehicles are powered by on-vehicle power sources, such as pure electric vehicles and hybrid electric vehicles, which meet the requirements of road traffic and safety regulations.

[0003] When fixing the existing battery pack to the vehicle body, the battery pack is usually fixed to the vehicle body by multiple bolts. During the battery pack assembly on the production line, multiple bolts need to be assembled and tightened in sequence, resulting in relatively low production efficiency; during the after-sales maintenance of the battery pack, multiple bolts need to be removed in sequence, resulting in relatively low after-sales maintenance efficiency, high maintenance costs, and repeated disassembly and installation of the bolts are likely to cause bolt damage, and the bolts need to be replaced in a timely manner. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a self-locking structure for a battery pack and a vehicle, aiming to solve the technical problems of low efficiency, high maintenance cost, and easy damage of parts during the disassembly and assembly of the existing battery pack.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] In a first aspect, the utility model provides a self-locking structure for a battery pack, including: a mounting base having a guiding channel with an open end and a locking groove communicating with the guiding channel; a locking assembly including an elastic member disposed in the guiding channel and a locking member disposed in the guiding channel; a moving assembly including a moving member adapted to the guiding channel and a fixing member connected to the moving member and adapted to be connected to the battery pack; and a releasing assembly disposed on the mounting base and adapted to the locking member.

[0007] Among them, the locking process is as follows: the moving member overcomes the elastic force of the elastic member, pushes the locking member away from the locking position, the moving member enters the locking groove, and the locking member is reset to the locking position under the action of the elastic member to prevent the moving member from entering and leaving the locking groove.

[0008] The releasing process is as follows: the releasing assembly drives the locking member to overcome the elastic force of the elastic member and move away from the locking position to the releasing position, the moving member leaves the locking groove, the releasing assembly is released, and the locking member is reset to the locking position under the action of the elastic member.

[0009] In some implementations, the guiding channel includes an access channel section and a locking channel section that are connected to each other. The connection between the access channel section and the locking channel section communicates with the locking groove, and the communication shape between the access channel section and the locking groove is zigzag.

[0010] In some implementations, the guiding channel is a trough-shaped structure with one end open, and the battery pack self-locking structure further includes a first cover plate covering the locking channel section.

[0011] In some implementations, the mounting base has a first blocking portion and a second blocking portion within the guiding channel; when the locking member abuts against the first blocking portion, the locking member is in the locked position; when the locking member abuts against the second blocking portion, the locking member is in the released position.

[0012] In some implementations, the mounting base has a first fixing portion within the guiding channel, the locking member has a second fixing portion, and two ends of the elastic member are respectively disposed on the first fixing portion and the second fixing portion.

[0013] In some implementations, the moving member is a wheel-shaped structure, the fixing member has a fixing shaft, and the moving member is sleeved on the fixing shaft.

[0014] In some implementations, a clamping groove is provided at the extending end of the fixing shaft extending out of the moving member, and a clamping member for preventing the moving member from disengaging is arranged in the clamping groove.

[0015] In some implementations, the release assembly includes a release member and a central shaft. The release member is rotatably connected to the mounting base through the central shaft, and a pulling hole is provided in the release member; a release opening communicating with the guiding channel is provided in the mounting base; the locking member has a pulling portion, the pulling portion extends out of the release opening and extends into the pulling hole, and the release member can drive the pulling portion to move when rotating.

[0016] In some implementations, the release member is disposed on a side of the mounting base away from the battery pack, a receiving groove for the release member to rotate is further provided in the mounting base, and the battery pack self-locking structure further includes a second cover plate covering the receiving groove.

[0017] In a second aspect, the present utility model further provides a vehicle, including the battery pack self-locking structure according to any one of the above implementations.

[0018] The self-locking structure of the battery pack and the vehicle provided by the present utility model has at least the following technical effects compared with the prior art: When the self-locking structure of the battery pack is in use, the locking member originally in the locked position is pushed away by the movement of the moving member, and then the moving member enters the locking groove. The locking member is reset to the locked position under the elastic force of the elastic member, thereby preventing the moving member from entering and exiting the locking groove, achieving the self-locking effect of the battery pack. When the battery pack needs to be disassembled, the locking member is pulled from the locked position to the release position through the release assembly, and the moving member can come out of the locking groove. After releasing the release assembly, the locking member automatically resets to the locked position, realizing the manual release of the battery pack; the above structure enables the battery pack to improve efficiency during disassembly and assembly, reduce maintenance costs, and reduce the problem of easy damage to parts.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] It should be noted that when an element is referred to as "fixed to", "fixed", "connected to", "connected", "disposed on", "disposed", "fixedly disposed on" another element, a middle element may or may not exist. When two elements are referred to as "mated" or "adapted", there may be common mechanical connection relationships such as abutting, clamping, sleeving, threaded connection, etc. between the two elements, which can be specifically determined according to the conventional selection of those skilled in the art. In this article, "a plurality of" refers to two or more quantities; "several" refers to one or more quantities.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs.

[0028] Please refer to Figures 1 to 3 , and the vehicle provided by the embodiment of the present utility model will be described in detail below.

[0029] Please refer to Figures 1 to 3 , the embodiment of the present utility model provides a battery pack self-locking structure 1, including: a mounting seat 10 having a guiding channel 11 with one end open and a locking groove 12 communicating with the guiding channel 11; a locking assembly 20 including an elastic member 21 disposed in the guiding channel 11 and a locking member 22 disposed in the guiding channel 11; a moving assembly 30 including a moving member 31 adapted to the guiding channel 11 and a fixing member 32 connected to the moving member 31 and adapted to be connected to the battery pack; and a releasing assembly 40 disposed on the mounting seat 10 and adapted to the locking member 22.

[0030] As Figure 2 and Figure 3 shown, wherein, the locking process is as follows: the moving member 31 overcomes the elastic force of the elastic member 21, pushes the locking member 22 away from the locking position, the moving member 31 enters the locking groove 12, and the locking member 22 is reset to the locking position under the action of the elastic member 21 to prevent the moving member 31 from entering and exiting the locking groove 12; the releasing process is as follows: the releasing assembly 40 drives the locking member 22 to overcome the elastic force of the elastic member 21 and move away from the locking position to the releasing position, the moving member 31 leaves the locking groove 12, the releasing assembly 40 is released, and the locking member 22 is reset to the locking position under the action of the elastic member 21.

[0031] Specifically, one end of the guiding channel 11 is closed and the other end is open in the length extension direction. The moving member 31 enters the guiding channel 11 from the open end. The cross-sectional shape of the open end can be tapered with a decreasing size from the outside to the inside to facilitate the entry of the moving member. The elastic member 21 can be a spring, an elastic column, etc. The locking member 22 can be a block structure, a spherical structure, etc. The moving member 31 can be a rolling structure, a sliding structure, etc. The fixing member 32 can be a block structure, a plate structure, etc. The battery pack is connected to the fixing member 32 through the fastener 34. The battery pack can drive the moving member 31 to move through the fixing member 32 to realize the disassembly and assembly of the battery pack.

[0032] Compared with the prior art, the battery pack self-locking structure 1 provided by the embodiment of the present utility model has at least the following technical effects: When the battery pack self-locking structure 1 is in use, the locking member 22 originally in the locking position is pushed away by the movement of the moving member 31, and then the moving member 31 enters the locking groove 12. The locking member 22 is reset to the locking position under the elastic force of the elastic member 21, so as to prevent the moving member 31 from entering and exiting the locking groove 12, realizing the self-locking effect of the battery pack. When the battery pack needs to be disassembled, the locking member 22 is pulled from the locking position to the release position through the release assembly 40, and the moving member 31 can come out of the locking groove 12. After releasing the release assembly 40, the locking member 22 automatically resets to the locking position, realizing the manual release of the battery pack; The above structure enables the battery pack to improve efficiency, reduce maintenance costs, and reduce the problem of easy damage to parts during disassembly and assembly.

[0033] The following specifically illustrates the specific structures of the mounting seat 10, the locking assembly 20, the moving assembly 30, and the release assembly 40.

[0034] Please refer to Figure 1 and Figure 2 In some embodiments, the guiding channel 11 includes an access channel section 111 and a locking channel section 112 that are connected to each other. The connection between the access channel section 111 and the locking channel section 112 is communicated with the locking groove 12, and the communication shape between the access channel section 111 and the locking groove 12 is zigzag. In this embodiment, the moving member 31 enters from the open end of the access channel section 111 and moves into the locking groove 12; the locking member 22 reciprocates in the locking channel section 112.

[0035] By setting the communication shape between the access channel section 111 and the locking groove 12 to be zigzag, the difficulty of the moving member 31 getting out can be relatively increased, and when the locking ability of the locking member 22 decreases, the difficulty of the battery pack falling off can be increased.

[0036] For the convenience of disassembly and assembly of the elastic member 21 and the locking member 22, please refer to Figure 1 and Figure 2, in some embodiments, the guiding channel 11 is a groove-shaped structure with one end open, and the battery pack self-locking structure 1 further includes a first cover plate 50 covering the locking channel section 112. It can be understood that the circumferential side of the guiding channel 11 (here, the circumferential side should be interpreted in a broad sense, not limited to regular shapes such as circular or rectangular shapes or irregular shapes) is not closed but open, which facilitates the disassembly and assembly of the elastic member 21 and the locking member 22. The first cover plate 50 can at least block the elastic member 21 to prevent the elastic member 21 from falling off and failing, and prevent other structures, sundries, dust, etc. from interfering.

[0037] Among them, the first cover plate 50 can be adapted to the edge structure of the locking channel section 112 by detachable means such as snap connection or threaded connection to realize the maintenance and replacement of components.

[0038] Please refer to Figure 1 and Figure 2 , in some embodiments, the mounting seat 10 has a first blocking portion 13 and a second blocking portion 14 in the guiding channel 11; when the locking member 22 abuts against the first blocking portion 13, the locking member 22 is in the locking position; when the locking member 22 abuts against the second blocking portion 14, the locking member 22 is in the release position. Specifically, the first blocking portion 13 and the second blocking portion 14 can be formed by the limiting corners directly formed by the mounting seat 10, and can be limiting grooves, limiting posts, etc. provided in the guiding channel 11.

[0039] For example, when both the first blocking portion 13 and the second blocking portion 14 are limiting corners, the locking member 22 directly abuts against the first blocking portion 13 and the second blocking portion 14 through surface-to-surface contact. Another example is that when both the first blocking portion 13 and the second blocking portion 14 are limiting posts, a limiting groove with a corresponding shape is provided on the surface of the locking member 22, and the limiting effect of the locking member 22 is realized through the abutment of the limiting post and the limiting groove.

[0040] With such a setting, the locking member 22 has relatively clear locking and release positions, rather than being limited by the natural state of the elastic member 21, so that the locking reliability and judgment of the locking member 22 are higher.

[0041] Please refer to Figure 1 and Figure 2 , in some embodiments, the mounting seat 10 has a first fixing portion 15 in the guiding channel 11, the locking member 22 has a second fixing portion 221, and both ends of the elastic member 21 are respectively arranged on the first fixing portion 15 and the second fixing portion 221. Specifically, the first fixing portion 15 and the second fixing portion 221 can be columnar structures, hook-shaped structures, etc., and the first fixing portion 15 and the second fixing portion 221 can be of different shapes.

[0042] When both the first fixing part 15 and the second fixing part 221 are columnar structures, the elastic member 21 can be a spring with a relatively large aperture, so that the two ends of the elastic member 21 can be respectively sleeved on the first fixing part 15 and the second fixing part 221. At this time, there is no need to mechanically connect the elastic member 21 to the first fixing part 15 and the second fixing part 221. When both the first fixing part 15 and the second fixing part 221 are hook-shaped structures, the elastic member 21 can be an ordinary spring. The elastic member 21 can be adapted to the mounting seat 10 and the locking member 22 by means of tying, or by bending the two ends of the elastic member 21 into hook shapes. Of course, other structural forms can also be adopted, which will not be elaborated here.

[0043] By providing the first fixing part 15 and the second fixing part 221, the elastic member 21 can be more reliably adapted to the mounting seat 10 and the locking member 22, preventing the elastic member 21 from falling off and failing.

[0044] Please refer to Figure 1 , in some embodiments, the moving member 31 is a wheel-shaped structure, the fixing member 32 has a fixing shaft 321, and the moving member 31 is sleeved on the fixing shaft 321. In this embodiment, the moving member 31 is a wheel-shaped structure, which can be sleeved on the fixing shaft 321 and can rotate relative to the fixing shaft 321. On the one hand, the rolling mode has a smaller moving friction force than the sliding mode and is smoother during the moving process. On the other hand, the moving member 31 and the fixing shaft 321 can rotate relative to each other, which can avoid rigid wear between the moving member 31 and the fixing member 32.

[0045] In order to improve the cooperation reliability between the moving member 31 and the fixing member 32, please refer to Figure 1 , in some embodiments, a clamping groove 3211 is provided at the protruding end of the fixing shaft 321 extending out of the moving member 31, and a clamping member 33 for preventing the moving member 31 from disengaging is arranged in the clamping groove 3211. Specifically, the protruding end of the fixing shaft 321 extending out of the moving member 31, that is, the end of the fixing shaft 321 away from the battery pack, is provided with the clamping groove 3211, the clamping member 33 is arranged in the clamping groove 3211, and the outer contour dimension of the clamping member 33 is larger than the inner contour dimension of the moving member 31. For example, the clamping member 33 can be a snap ring, a rigid ring, a binding wire, etc., so as to prevent the moving member 31 from disengaging, and in the locked state, the position reliability of the battery pack is ensured by preventing the movement of the moving member 31, and the cooperation reliability between the fixing member 32 and the moving member 31 is ensured.

[0046] Please refer to Figure 1 and Figure 3, in some embodiments, the release component 40 includes a release member 41 and a central shaft 42. The release member 41 is rotatably connected to the mounting base 10 through the central shaft 42, and the release member 41 is provided with a pulling hole 411; the mounting base 10 is provided with a release opening 16 communicating with the guiding channel 11; the locking member 22 has a pulling portion 222, the pulling portion 222 extends out of the release opening 16 and extends into the pulling hole 411, and the release member 41 can drive the pulling portion 222 to move when rotating.

[0047] Specifically, the release member 41 can be in a sheet-like structure or a rod-like structure, etc. The central shaft 42 can be fixed on the mounting base 10. The release member 41 is sleeved on the central shaft 42 and can rotate relative to the central shaft 42. The pulling hole 411 is an elongated hole. The length extension direction of the release opening 16 and the reset direction of the elastic member 21 are preferably on the same straight line. The pulling portion 222 extends out of the release opening 16 and extends into the pulling hole 411, and a snap ring can be used to prevent the pulling portion 222 from detaching from the pulling hole 411 to ensure the reliability of the cooperation.

[0048] When the release member 41 rotates, it can drive the pulling portion 222 to generate relative displacements in both the pulling hole 411 and the release opening 16, so that the rotational movement is converted into a linear movement, and the manual release of the locking member 22 can be realized.

[0049] Since the gap between the battery pack and the mounting base 10 is relatively small, in order to simplify the operation difficulty and improve the structural reliability, please refer to Figure 3 , in some embodiments, the release member 41 is disposed on the side of the mounting base 10 away from the battery pack. The mounting base 10 is further provided with a receiving groove 17 for the release member 41 to rotate. The battery pack self-locking structure 1 further includes a second cover plate 60 covering the receiving groove 17.

[0050] Specifically, the receiving groove 17 communicates with the guiding channel 11 through the release opening 16. One end of the release member 41 away from the pulling hole 411 extends out of the receiving groove 17 for the convenience of the operator to pull; the receiving groove 17 can be in an arch shape to provide a larger rotation space for the release member 41. The second cover plate 60 can block part of the release member 41 and the central shaft 42 to prevent other structures and sundries, dust, etc. from affecting the reliability of the manual release.

[0051] Among them, the second cover plate 60 can be adapted to the edge structure of the receiving groove 17 by detachable means such as snap connection and threaded connection to realize the maintenance and replacement of components.

[0052] In addition, in other embodiments, the release component 40 may only include the release member 41. The release member 41 may cooperate with the pulling portion 222 through the pulling hole 411, or the release member 41 may be directly connected to the pulling portion 222 without providing the pulling hole 411. The release member 41 does not need to be rotatably connected to the mounting seat 10. By directly manually pulling the release member 41 to move in the locking direction, the locking member 22 can be driven to achieve manual release. When the release member 41 is released, the locking member 22 automatically resets under the elastic force of the elastic member 21 and maintains the locked state.

[0053] Based on the same inventive concept, an embodiment of the present utility model further provides a vehicle, including the battery pack self-locking structure 1 described in any one of the above embodiments, and a battery pack adapted to the fixing member 32. Of course, the vehicle may further include conventional mechanical, electronic, communication and other structures such as a vehicle body, a control unit, and a power unit to form a vehicle with complete functions and achieve the normal use effect of the vehicle.

[0054] Since the vehicle adopts the battery pack self-locking structure 1 described in any one of the above embodiments, it has the same technical effects as the above battery pack self-locking structure 1, which will not be elaborated here.

[0055] It can be understood that the various parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of the various combined embodiments will not be elaborated here. After this explanation, it can be considered that the description of the present utility model has recorded the various combined embodiments and can support different combined embodiments.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
