Description

Technical Field

[0001] This invention relates to the technical field of vehicle management, and in particular to a battery module, a battery locking assembly, and an electric vehicle. Background Technology

[0002] Carbon neutrality is a shared mission for humanity, and accelerating the transformation of the energy structure and improving the user experience have become common aspirations for everyone and all industries. Currently, in the field of electric vehicles, especially electric two-wheelers, battery module installation structures present a diverse range of solutions.

[0003] There are two modes in the installation structure of battery modules: The first method involves attaching and detaching the battery module to the guide rail bracket on the vehicle tube via a sliding insertion and direct access method, i.e., a sliding removal and installation mode (or a direct access mode). The second method involves mounting and dismounting the battery module onto the guide rail bracket via a rotating side-mounting method, also known as the side-rotating disassembly mode (or side-mounting mode).

[0004] For the two modes mentioned above, traditional solutions require the development of battery modules with different structures, meaning that two battery modules are needed for each installation method, resulting in poor compatibility of the battery modules. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery module, battery locking assembly and electric vehicle with better adaptability.

[0006] The objective of this invention is achieved through the following technical solution: A battery module, comprising: The module body includes a discharge end and a lateral locking end arranged opposite each other. A rotary connection structure is provided on one side of the discharge end of the module body, and a side-locking connection structure is provided on the lateral locking end. A sliding limiting structure is provided on the outer wall of the module body, and a sliding connection structure is also provided on the outer wall of the module body. The sliding connection structure and the sliding limiting structure are located on the same side of the module body. The sliding limiting structure is used to assist the module body in sliding into position along its own length extension direction and to restrict longitudinal movement. In side-access mode, the battery module can rotate clockwise or counterclockwise around the rotating connection structure so that the rotating connection structure can be locked or unlocked with an external rotary lock. In direct access mode, the battery module can slide back and forth in a straight line along the length extension direction of the sliding limit structure, so that the sliding connection structure can be locked or unlocked with the external sliding lock head.

[0007] A side-access battery box includes a battery module, a side-access discharge seat, and a rotary lock head as described in any of the above embodiments. The side-access discharge seat is disposed on one side of the discharge end and is electrically connected to the discharge end. The rotary lock head is disposed on one side of the side-locking end and is locked and connected to the side-locking connection structure.

[0008] A direct-discharge battery box includes a battery module, a direct-discharge socket, a sliding connector, and a sliding lock as described in any of the above embodiments. The direct-discharge socket is disposed on one side of the discharge end and is electrically connected to the discharge end. The sliding connector is disposed on one side of the sliding limiting structure and is slidably connected to the sliding limiting structure. The sliding lock is disposed on the side of the battery module near the direct-discharge socket and is locked to the sliding connector.

[0009] An electric vehicle includes a vehicle tube, a side-mounted battery box as described in any of the above embodiments, and / or a direct-mounted battery box as described in any of the above embodiments, wherein the side-mounted battery box and / or the direct-mounted battery box are mounted on the vehicle tube.

[0010] Compared with the prior art, the present invention has at least the following advantages: 1. In the side-access mode, i.e. in the scenario of side-rotation assembly and disassembly of the battery module, rotate the battery module clockwise around the rotating connection structure so that the rotating connection structure can lock with the external rotating lock head to achieve side-rotation assembly of the battery module; conversely, unlock the rotating connection structure with the external rotating lock head and rotate the battery module counterclockwise around the rotating connection structure to achieve side-rotation disassembly of the battery module. 2. In the direct-access mode, i.e., in the scenario of sliding assembly and disassembly of the battery module, the battery module is slid in a straight line along the length extension direction of the sliding limit structure towards the sliding lock head. Since the sliding connection structure and the sliding limit structure are located on the same side of the module body, the sliding limit structure assists the module body to slide into place along its own length extension direction and restricts longitudinal movement, so that the sliding connection structure locks with the external sliding lock head, realizing the sliding assembly of the battery module; conversely, the sliding connection structure is unlocked from the external sliding lock head, and the battery module is slid in a straight line along the length extension direction of the sliding limit structure away from the sliding lock head. The sliding limit structure assists the module body to slide along its own length extension direction, realizing the sliding disassembly of the battery module; 3. The battery module described above can be used in both side-flush and direct-flush modes, eliminating the need to develop battery modules with different structures, thus improving the adaptability of the battery module.

Detailed Implementation

[0013] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0014] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] This application provides a battery module, including a module body. The module body includes a discharge end and a side-locking end arranged opposite each other. A rotary connection structure is provided on one side of the discharge end of the module body, and a side-locking connection structure is provided on the side-locking end. A sliding limiting structure is provided on the outer wall of the module body, and a sliding connection structure is also provided on the outer wall of the module body. The sliding connection structure and the sliding limiting structure are located on the same side of the module body. In the side-access mode, the battery module can rotate clockwise or counterclockwise around the rotary connection structure to lock or unlock the rotary connection structure with an external rotary lock. In the direct access mode, the battery module can slide back and forth in a straight line along the length extension direction of the sliding limiting structure to lock or unlock the sliding connection structure with an external sliding lock.

[0017] In the side-access mode, i.e., during the side-rotation assembly / disassembly of the battery module, the battery module is rotated clockwise around the rotating connection structure to engage with the external rotary lock, thus achieving side-rotation assembly. Conversely, by unlocking the rotating connection structure from the external rotary lock, the battery module is rotated counterclockwise around the rotating connection structure to achieve side-rotation disassembly. In the direct-access mode, i.e., during the sliding assembly / disassembly of the battery module, the battery module is slid linearly along the length of the sliding limit structure towards the sliding lock. Since the sliding connection structure and the sliding limit structure are located within the module... On the same side of the main body, the sliding limiting structure assists the main body of the module to slide into place along its own length extension direction and restricts longitudinal movement, so that the sliding connection structure locks with the external sliding lock head, realizing the sliding assembly of the battery module; conversely, by unlocking the sliding connection structure from the external sliding lock head, the battery module slides in a straight line away from the sliding lock head along the length extension direction of the sliding limiting structure, and the sliding limiting structure assists the main body of the module to slide along its own length extension direction, realizing the sliding disassembly of the battery module; the above-mentioned battery module can be used for both side-access mode and direct access mode, without the need to develop battery modules with different structures, making the battery module more adaptable.

[0018] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 4As shown, in one embodiment, the battery module 10 is adapted to either a side-flush mode or a direct-flush mode, giving the battery module 10 better adaptability.

[0019] like Figures 5 to 7 As shown, in one embodiment, the battery module 10 includes a module body 100, which includes a discharge end 200 and a lateral locking end 300 arranged opposite each other, i.e., the discharge end 200 and the lateral locking end 300 are located at opposite ends of the module body 100. The discharge end 200 of the module body 100 has a rotary connection structure 210 on one side, and the lateral locking end 300 has a side-locking connection structure 310. The outer wall of the module body 100 has a sliding limiting structure 110, and the outer wall of the module body 100 also has a sliding connection structure 120, and the sliding connection structure 120 and the sliding limiting structure 110 are located on the same side of the module body 100; the sliding limiting structure 110 is used to assist the module body 100 in sliding into position along its own length extension direction and to restrict longitudinal movement.

[0020] like Figure 1 , Figure 2 , Figures 5 to 7 As shown, in side-mounted mode, the battery module 10 can rotate clockwise or counterclockwise around the rotating connection structure 210 (rotation direction is as follows). Figure 2 (As shown by arrow A), so that the rotary connection structure 210 can be locked or unlocked with the external rotary lock head 20; specifically, when the battery module 10 rotates clockwise around the rotary connection structure 210, the rotary connection structure 210 can be locked with the external rotary lock head 20; when the battery module 10 rotates clockwise around the rotary connection structure 210, the rotary connection structure 210 can be unlocked with the external rotary lock head 20.

[0021] like Figures 3 to 7 As shown, in the direct-access mode, the battery module 10 can extend along the length direction of the sliding limiting structure 110 (i.e., as shown in the figure). Figure 4 The sliding connection structure 120 slides back and forth in a straight line (as shown by arrow B) to lock or unlock with the external sliding lock head 30. Specifically, when the battery module 10 slides in a straight line along the length extension direction of the sliding limiting structure 110 toward the sliding lock head 30, the sliding connection structure 120 locks with the external sliding lock head 30; when the battery module 10 slides in a straight line along the length extension direction of the sliding limiting structure 110 away from the sliding lock head 30, the sliding connection structure 120 unlocks with the external sliding lock head 30.

[0022] In the side-access mode, i.e., during the side-rotation assembly / disassembly scenario of the battery module 10, the battery module 10 is rotated clockwise around the rotating connection structure 210 to lock the rotating connection structure 210 with the external rotating lock head 20, thus achieving side-rotation assembly of the battery module 10. Conversely, the rotating connection structure 210 is unlocked from the external rotating lock head 20, and the battery module 10 is rotated counterclockwise around the rotating connection structure 210 to achieve side-rotation disassembly of the battery module 10. In the direct access mode, i.e., during the sliding assembly / disassembly scenario of the battery module 10, the battery module 10 is slid in a straight line along the length extension direction of the sliding limit structure 110 towards the sliding lock head 30. Since the sliding connection structure 120 and the sliding limit structure 110 are located within the module... On the same side of the main body 100, the sliding limiting structure 110 assists the main body 100 in sliding into place along its own length extension direction and restricts longitudinal movement, so that the sliding connecting structure 120 locks with the external sliding lock head 30, realizing the sliding assembly of the battery module 10; conversely, by unlocking the sliding connecting structure 120 from the external sliding lock head 30, the battery module 10 slides in a straight line away from the sliding lock head 30 along the length extension direction of the sliding limiting structure 110, and the sliding limiting structure 110 assists the main body 100 in sliding along its own length extension direction, realizing the sliding disassembly of the battery module 10; the above-mentioned battery module 10 can be used for both side-access mode and direct access mode, without the need to develop battery modules 10 with different structures, making the battery module 10 more adaptable.

[0023] like Figure 5 As shown, the discharge end 200 and the lateral locking end 300 are both disposed away from the sliding limiting structure 110, that is, the discharge end 200 and the lateral locking end 300 are not coplanar with the sliding limiting structure 110, so as to avoid interference with the sliding limiting structure 110 in the side-access mode and interference with the lateral locking end 300 in the direct access mode, thereby enabling the battery module 10 to be reliably plugged into the external power socket in both the side-access mode and the direct access mode.

[0024] like Figures 5 to 8 As shown, in one embodiment, the side-lock connection structure 310 includes a side-lock limiting part 312 and a first locking part 314. The side-lock limiting part 312 is used to restrict the longitudinal movement of the lateral locking end 300, thereby assisting the first locking part 314 in completing the lateral locking with the rotary lock head 20, so that the first locking part 314 and the rotary lock head 20 can be locked into place quickly and reliably. In this embodiment, the first locking part 314 is a rotary lock hole, which is adapted to the rotary lock head 20. Further, the side-lock limiting part 312 is a guide protrusion structure, and the first locking part 314 is provided on the side-lock limiting part 312, so that the side-lock limiting part 312 can better assist the first locking part 314 in completing the lateral locking with the rotary lock head 20.

[0025] like Figures 5 to 8 As shown, in one embodiment, the side-locking connection structure 310 is a side-access slider, which is detachably connected to the lateral locking end 300 of the module body 100 to facilitate the installation and removal of the side-access slider, and also to facilitate the positioning, maintenance, or replacement of the side-access slider. In this embodiment, the side-access slider is screwed to the lateral locking end 300 of the module body 100, making the side-access slider detachably connected to the lateral locking end 300. Specifically, the battery module 10 also includes a first fastener 400. The side-access slider has a first through hole 3102, and the module body 100 has a first screw hole 102. The first fastener 400 is screwed to the first screw hole 102 through the first through hole 3102, so that the side-access slider is screwed to the lateral locking end 300 of the module body 100. It should be noted that the first fastener 400 can be a screw or a bolt.

[0026] It is understood that in other embodiments, the side-access slider is not limited to being screwed to the lateral locking end 300 of the module body 100. For example, the side-access slider is snapped onto the lateral locking end 300 of the module body 100.

[0027] like Figures 5 to 9 As shown, in one embodiment, the module body 100 has a first mounting groove 104, and the side-access slider is detachably installed in the first mounting groove 104, so that the side-access slider is received and fixed on the module body 100, thereby making the structure of the battery module 10 more compact. In one embodiment, the battery module 10 also includes a decorative cover 500, and the module body 100 has a second mounting groove 106 that communicates with the first mounting groove 104. The decorative cover 500 is detachably installed in the second mounting groove 106, so that the decorative cover 500 can be flexibly selected for use as needed, better meeting the requirement of a neat appearance for the battery module 10. It should be noted that before assembling the decorative cover 500, the side-access slider can be removed or not, improving the ease of use of the battery module 10.

[0028] like Figures 5 to 9 As shown, in one embodiment, the decorative cover 500 is installed in the second mounting groove 106 after the side-access slider is removed, avoiding interference between the decorative cover 500 and the side-access slider, and simplifying the structure of the decorative cover 500. It is understood that in other embodiments, the side-access slider may not be removed. In this embodiment, the side-access slider is detachably installed in the first mounting groove 104, and the decorative cover 500 is detachably installed in the second mounting groove 106. A clearance groove is formed on the side of the decorative cover 500 adjacent to the side-access slider, and the clearance groove is correspondingly provided with the decorative cover 500 to avoid interference between the decorative cover 500 and the side-access slider.

[0029] like Figures 5 to 9 As shown, further, the decorative cover 500 is screwed to the lateral locking end 300 of the module body 100, making the decorative cover 500 detachably connected to the lateral locking end 300. Specifically, the battery module 10 also includes a second fastener. The decorative cover 500 has a second through hole 502, and the module body 100 has a second screw hole communicating with the second mounting groove 106. The second fastener is screwed to the second screw hole through the second through hole 502. In this embodiment, before installing the decorative cover 500, the side-mounting slider is removed from the module body 100. The second fastener and the first fastener 400 are the same fastener, and the second screw hole and the first screw hole 102 are the same screw hole. It should be noted that the second fastener can be a screw or a bolt. It is understood that in other embodiments, the decorative cover 500 is not limited to being screwed to the lateral locking end 300 of the module body 100. For example, the decorative cover 500 is snapped onto the lateral locking end 300 of the module body 100.

[0030] like Figures 3 to 7 , Figure 9 As shown, in one embodiment, the sliding limiting structure 110 includes a longitudinal limiting part 112 and a lateral limiting part 114. The longitudinal limiting part 112 is used to restrict the longitudinal movement of the module body 100, and the lateral limiting part 114 is used to assist the module body 100 to slide linearly along its own length extension direction. In the direct-access mode, the battery module 10 can slide back and forth linearly along the length extension direction of the lateral limiting part 114, while the longitudinal limiting part 112 restricts the longitudinal movement of the module body 100, so that the sliding connection structure 120 can be locked or unlocked with the external sliding lock head 30. Especially in the locking stage with the sliding lock head 30, under the combined action of the longitudinal limiting part 112 and the lateral limiting part 114, the sliding connection structure 120 can be quickly and reliably aligned and locked with the external sliding lock head 30. In this embodiment, the sliding connection structure 120 is provided on the lateral limiting part 114, making the structure of the sliding limiting structure 110 more compact. When the module body 100 slides into place in a straight line along its own length extension direction, the sliding connection structure 120 can quickly lock with the sliding lock head 30.

[0031] like Figures 3 to 7 , Figure 9As shown, in one embodiment, the longitudinal limiting portion 112 is distributed on opposite sides of the lateral limiting portion 114, allowing the lateral limiting portion 114 to more smoothly assist the module body 100 in sliding linearly along its own length extension direction, thereby improving the sliding stability of the battery module 10 in the direct-drive mode, that is, ensuring the module body 100 slides linearly on the same horizontal plane. In one embodiment, the lateral limiting portion 114 is a groove structure, and the longitudinal limiting portion 112 is a toothed slide rail. The number of longitudinal limiting portions 112 is at least two, allowing the lateral limiting portion 114 to more smoothly assist the module body 100 in sliding linearly along its own length extension direction, thereby improving the sliding stability of the battery module 10 in the direct-drive mode, that is, ensuring the module body 100 slides linearly on the same horizontal plane.

[0032] like Figure 1 , Figure 2 , Figures 10 to 12 As shown, this application also provides a side-access battery box 40, including the battery module 10, side-access discharge seat 42 and rotary lock head 20 described in any of the above embodiments. The side-access discharge seat 42 is disposed on one side of the discharge end 200 and is electrically connected to the discharge end 200. The rotary lock head 20 is disposed on one side of the side-locking end 300 and is locked and connected to the side-locking connection structure 310.

[0033] In the side-access battery box 40 described above, in the side-access mode, i.e., in the scenario of side-rotation assembly / disassembly of the battery module 10, the battery module 10 is rotated clockwise around the rotating connection structure 210 so that the rotating connection structure 210 can be locked with the external rotating lock head 20, thereby realizing the side-rotation assembly of the battery module 10; conversely, the rotating connection structure 210 can be unlocked from the external rotating lock head 20, and the battery module 10 is rotated counterclockwise around the rotating connection structure 210, thereby realizing the side-rotation disassembly of the battery module 10; in this embodiment, the side-access discharge base 42 is provided with a discharge interface 422, and the discharge end 200 is provided with a discharge female plug 201. The discharge female plug 201 is used to be inserted into the discharge interface 422 when the rotating connection structure 210 is locked with the rotating lock head 20, so that the side-access discharge base 42 is electrically connected to the discharge end 200.

[0034] The battery module 10 of the aforementioned side-access battery box 40 is applicable not only to the side-access mode but also to the direct-access mode, eliminating the need to develop battery modules 10 with different structures, thus improving the adaptability of the battery module 10. When the battery module 10 is suitable for the direct mounting mode, that is, in the scenario of sliding assembly and disassembly of the battery module 10, the battery module 10 is slid in a straight line along the length extension direction of the sliding limiting structure 110 towards the sliding lock head 30. Since the sliding connection structure 120 and the sliding limiting structure 110 are located on the same side of the module body 100, the sliding limiting structure 110 assists the module body 100 to slide into place along its own length extension direction and restricts longitudinal movement, so that the sliding connection structure 120 locks with the external sliding lock head 30, realizing the sliding assembly of the battery module 10. Conversely, the sliding connection structure 120 is unlocked from the external sliding lock head 30, and the battery module 10 is slid in a straight line along the length extension direction of the sliding limiting structure 110 away from the sliding lock head 30. The sliding limiting structure 110 assists the module body 100 to slide along its own length extension direction, realizing the sliding disassembly of the battery module 10.

[0035] like Figure 2 , Figure 7 , Figure 8 , Figure 11 As shown, in one embodiment, the rotary lock head 20 has a side-access groove 22 and a first locking tongue 24 on the side near the battery module 10. The side-lock connection structure 310 is slidably connected to the side-access groove 22. The side-lock connection structure 310 has a first locking hole 302. The first locking tongue 24 is locked to the first locking hole 302, so that the side-lock connection structure 310 can reliably slide into place along the side-access groove 22, and the first locking tongue 24 can quickly and reliably lock into place in the first locking hole 302. In this embodiment, the side-lock connection structure 310 includes a side-lock limiting part 312 and a first locking part 314. The side-lock limiting part 312 is slidably connected to the side-lock groove, so that the side-lock limiting part 312 restricts the longitudinal movement of the lateral locking end 300, thereby assisting the first locking part 314 and the first locking tongue 24 to complete the lateral locking, so that the first locking part 314 and the rotary lock head 20 can quickly and reliably lock into place. Specifically, the first locking part 314 is the first locking hole 302, and the side locking limiting part 312 is the side locking guide rail.

[0036] like Figure 10 and Figure 12As shown, in one embodiment, the rotary connection structure 210 is provided with a rotary shaft groove 304, and the side discharge seat 42 is provided with a rotary shaft protrusion 421 on the side near the battery module 10, so that the battery module 10 can rotate clockwise or counterclockwise around the rotary connection structure 210. In this embodiment, there are two rotary shaft protrusions and two rotary shaft grooves 304, with each rotary shaft protrusion corresponding to a specific rotary shaft groove 304. The side discharge seat 42 is provided with a discharge interface 422, which is located between the two rotary shaft protrusions. When installing the battery module 10, the battery module 10 is rotated clockwise around one of the rotary shaft grooves 304 relative to the corresponding rotary shaft protrusion. The side lock limiting part 312 slides into place along the side lock groove. At this time, the other rotary shaft groove 304 cooperates with the corresponding rotary shaft protrusion, and then the first locking tongue 24 is locked with the first locking hole 302 to realize the side rotation assembly of the battery module 10. It is understood that in other embodiments, the positions of the rotating shaft protrusion and the rotating shaft groove 304 can be interchanged. For example, the rotating connection structure 210 is provided with a rotating shaft protrusion, and the side discharge seat 42 is provided with a rotating shaft groove 304 on the side near the battery module 10, and the rotating shaft protrusion and the rotating shaft groove 304 are rotatably connected.

[0037] like Figures 3 to 7 As shown, this application also provides a direct-discharge battery box 50, including the battery module 10, direct-discharge socket 52, sliding connecting seat 54, and sliding lock head 30 as described in any of the above embodiments. The direct-discharge socket 52 is disposed on one side of the discharge end 200 and is electrically connected to the discharge end 200. The sliding connecting seat 54 is disposed on one side of the sliding limiting structure 110 and is slidably connected to the sliding limiting structure 110. The sliding lock head 30 is disposed on the side of the battery module 10 near the direct-discharge socket 52 and is locked and connected to the sliding connecting structure 120.

[0038] The aforementioned direct-access battery box 50 allows the battery module 10 to slide linearly along the length extension direction of the sliding limiting structure 110 towards the sliding lock head 30. Since the sliding connection structure 120 and the sliding limiting structure 110 are located on the same side of the module body 100, the sliding limiting structure 110 assists the module body 100 to slide into place along its own length extension direction and restricts longitudinal movement, so that the sliding connection structure 120 locks with the external sliding lock head 30, realizing the sliding assembly of the battery module 10. Conversely, by unlocking the sliding connection structure 120 from the external sliding lock head 30, the battery module 10 slides linearly away from the sliding lock head 30 along the length extension direction of the sliding limiting structure 110. The sliding limiting structure 110 assists the module body 100 to slide along its own length extension direction, realizing the sliding disassembly of the battery module 10.

[0039] The battery module 10 of the aforementioned direct-access battery box 50 is applicable not only to the direct-access mode but also to the side-access mode, eliminating the need to develop battery modules 10 with different structures and thus improving the adaptability of the battery module 10. When the battery module 10 is used in the side-access mode, i.e., in the scenario of side-rotation assembly and disassembly of the battery module 10, the battery module 10 is rotated clockwise around the rotating connection structure 210 to lock the rotating connection structure 210 with the external rotating lock head 20, thereby achieving side-rotation assembly of the battery module 10; conversely, the rotating connection structure 210 is unlocked from the external rotating lock head 20, and the battery module 10 is rotated counterclockwise around the rotating connection structure 210 to achieve side-rotation disassembly of the battery module 10.

[0040] like Figure 4 and Figure 5 As shown, in one embodiment, the sliding lock head 30 is provided with a second locking tongue 32, which passes through the sliding connecting seat 54 and protrudes from the sliding connecting seat 54 on the side near the battery module 10. The sliding connecting structure 120 is a second lock hole, and the second locking tongue 32 is locked to the second lock hole, so that the sliding lock head 30 is reliably locked to the sliding connecting structure 120.

[0041] like Figures 13 to 16 As shown, the direct discharge base 52 is further fixed to the sliding connection base 54. In this embodiment, the direct discharge base 52 is provided with a discharge male plug. When the sliding connection structure 120 is locked with the external sliding lock head 30, the discharge female plug 201 is inserted into the discharge male plug.

[0042] like Figures 13 to 16 As shown, the sliding connecting seat 54 further includes a first lock cylinder hole 541 and a lock tongue hole 543, while the direct discharge seat 52 forms a second lock cylinder through hole 52a and a receiving cavity 52b, with the second lock cylinder through hole 52a communicating with the receiving cavity 52b. Further, the sliding lock head 30 includes a lock seat 33 and an extended lock tongue 34. The lock seat 33 is located within the receiving cavity 52b and connected to the direct discharge seat 52. The lock cylinder of the lock seat 33 passes through the second lock cylinder through hole 52a and the first lock cylinder hole 541, respectively. The extended lock tongue 34 is located on the side of the sliding connecting seat 54 opposite to the direct discharge seat 52. One end of the extended lock tongue 34 is connected to the lock cylinder, and the other end of the extended lock tongue 34 protrudes with a second lock tongue 32, allowing the lock cylinder to be connected to the second lock tongue 32 via the extended lock tongue 34. The second lock tongue 32 is movably disposed within the lock tongue hole 543.

[0043] like Figures 13 to 16As shown, further, the sliding connecting seat 54 has a movable clearance groove 521 on the side away from the direct discharge seat 52. The movable clearance groove 521 is connected to the latch hole 543 and the first lock cylinder hole 541 respectively. The extended latch 34 is located in the movable clearance groove 521, so that the extended latch 34 is better movable on the side of the sliding connecting seat 54 away from the direct discharge seat 52, and at the same time, the structure of the sliding connecting seat 54 is more compact.

[0044] like Figures 13 to 16 As shown, the extended latch 34 is further detachably connected to the lock cylinder for regular maintenance or replacement of the lock cylinder. In this embodiment, the extended latch 34 is screwed to the lock cylinder. Specifically, the sliding lock head 30 also includes a latch fastener 36. The extended latch 34 has a first through hole 341, and the lock cylinder has a first screw hole (not shown). The latch fastener 36 is screwed into the first screw hole through the first through hole 341, so that the extended latch 34 is screwed to the lock cylinder.

[0045] like Figures 13 to 16 As shown, the sliding connecting seat 54 further includes a cover plate 544. A slot 545 is provided on the side of the sliding connecting seat 54 opposite to the direct discharge seat 52. The slot 545 communicates with the movable clearance slot 521. The cover plate 544 covers the slot 545 to prevent foreign objects from entering the movable clearance slot 521, thus better protecting the movable clearance slot 521 and the expansion latch 34. Furthermore, an elastic element 343 protrudes from the side of the expansion latch 34 adjacent to the cover plate, which better buffers and dampens vibration when the expansion latch 34 moves within the movable clearance slot 521, and also allows the expansion latch 34 to better reset. In this embodiment, the elastic element 343 is a coil spring or elastic rubber. Figures 13 to 16 As shown, the sliding connector 54 further includes a buffer pad 546, which is disposed on the side of the sliding connector 54 facing away from the battery module 100. This allows the sliding connector 54 to be fastened to the vehicle tube 24 via the buffer pad 546, thus ensuring a secure connection between the sliding connector 54 and the vehicle tube 24, while also providing good cushioning and vibration reduction. In this embodiment, the buffer pad 546 is fixed between the sliding connector 54 and the vehicle tube 24 by a basic fastener 290. Furthermore, the sliding connector 54 has a third through hole 547, the buffer pad 546 has a fourth through hole 5462, and the vehicle tube 24 has a second screw hole. The basic fastener 290 is screwed into the second screw hole through the third through hole 547 and the fourth through hole 5462, thus fixing the sliding connector 54, the buffer pad 546, and the vehicle tube 24 together as a single unit. In this embodiment, both the third through hole 547 and the fourth through hole 5462 are oblong holes.

[0046] like Figures 13 to 16As shown, in one embodiment, the direct discharge socket 52 is detachably connected to the sliding connecting seat 54 to facilitate periodic maintenance and replacement of the direct discharge socket 52. In this embodiment, the sliding connecting seat 54 further includes a socket fastener 548. The sliding connecting seat 54 has a locking hole 549, and the direct discharge socket 52 has a screw hole 522. The socket fastener 548 is screwed into the locking hole 549 and the screw hole 522 respectively, so that the direct discharge socket 52 is locked to the sliding connecting seat 54 by the socket fastener 548. In this embodiment, the socket fastener 548 is a screw or bolt.

[0047] like Figures 13 to 16 As shown, the lock seat 33 is further detachably connected to the direct discharge base 52 for maintenance or replacement. In this embodiment, the sliding connecting base 54 also includes a vehicle lock fixing member 550. The lock seat 33 has a third screw hole, the direct discharge base 52 has a fifth through hole 523, and the sliding connecting base 54 has a sixth through hole 552. The vehicle lock fixing member 550 is screwed to the third screw hole through the sixth through hole 552 and the fifth through hole 523 in sequence, so that the lock seat 33 is detachably connected to the direct discharge base 52. Furthermore, the direct discharge base 52 has a vehicle lock limiting post, and the outer peripheral wall of the lock seat 33 is positioned on the vehicle lock limiting post, so that the lock seat 33 is reliably positioned within the direct discharge base 52.

[0048] like Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, in one embodiment, the sliding limiting structure 110 is a direct access groove, and the sliding connecting seat 54 is provided with a direct access slider 542 on the side near the battery module 10. The direct access groove and the direct access slider 542 are slidably connected, so that the sliding connecting seat 54 is slidably connected to the sliding limiting structure 110. In this embodiment, the direct access slider 542 is located in the direct access groove and is slidably connected to the sliding limiting structure 110. Further, the sliding limiting structure 110 includes a longitudinal limiting part 112 and a lateral limiting part 114. The direct access slider 542 is linearly slidably connected to the lateral limiting part 114 along the length extension direction of the module body 100, so that the lateral limiting part 114 can assist the module body 100 to slide linearly along its own length extension direction; the side of the direct access slider 542 is provided with a longitudinal sliding part 5422, and the longitudinal limiting part 112 slides into the longitudinal sliding part 5422 to limit the module. The module body 100 moves longitudinally; in the direct mode, the battery module 10 can slide back and forth in a straight line along the length extension direction of the lateral limiting part 114, while the longitudinal limiting part 112 restricts the longitudinal movement of the module body 100 so that the sliding connection structure 120 can lock or unlock with the external sliding lock head 30. Especially in the locking stage with the sliding lock head 30, under the combined action of the longitudinal limiting part 112 and the lateral limiting part 114, the sliding connection structure 120 can be quickly and reliably aligned and locked with the external sliding lock head 30.

[0049] like Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, further, the longitudinal limiting portion 112 is distributed on opposite sides of the lateral limiting portion 114, allowing the lateral limiting portion 114 to more smoothly assist the module body 100 in sliding linearly along its own length extension direction, thereby improving the sliding stability of the battery module 10 in the direct-access mode, that is, the module body 100 slides linearly and stably on the same horizontal plane. In this embodiment, both sides of the direct-access slider 542 are provided with longitudinal sliding portions 5422, making the sliding between the direct-access slider 542 and the module body 100 more stable.

[0050] like Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, the lateral limiting part 114 is a sliding groove structure, and the direct sliding block 542 is located inside the lateral limiting part 114 and slidably connected to the module body, so that the battery module 10 can slide back and forth in a straight line along the length extension direction of the lateral limiting part 114. In this embodiment, the longitudinal limiting part 112 is a toothed slide rail, and the longitudinal sliding part 5422 is a groove structure. The longitudinal limiting part 112 slides into the longitudinal sliding part 5422, so that the lateral limiting part 114 more smoothly assists the module body 100 to slide in a straight line along its own length extension direction, improving the stability of the sliding of the battery module 10 in the direct mode, that is, the module body 100 slides in a straight line stably on the same horizontal plane. In this embodiment, the longitudinal sliding part 5422 includes a longitudinal sliding groove 5423 and a linear sliding groove 5424 that are connected. The longitudinal limiting part 112 first slides into the linear sliding groove 5424 along the longitudinal direction through the longitudinal sliding groove 5423, and then slides into place in a straight line along the extension direction of the module body through the linear sliding groove 5424, which improves the reliability of the battery module 10 sliding in the direct take-up mode.

[0051] It is understood that in other embodiments, the positions of the direct-access slider 542 and the direct-access groove can be interchanged. For example, the sliding limiting structure 110 is the direct-access slider 542, and the sliding connecting seat 54 is provided with a direct-access groove on the side near the battery module 10, and the direct-access groove is slidably connected to the direct-access slider 542.

[0052] like Figures 1 to 4 As shown, this application also provides an electric vehicle 60, including a vehicle tube 62, a side-access battery box 40 as described in any of the above embodiments, and / or a direct-access battery box 50 as described in any of the above embodiments, wherein the side-access battery box 40 and / or the direct-access battery box 50 are mounted on the vehicle tube 62.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, the electric vehicle 60 includes a vehicle tube 62 and a side-access battery box 40 as described in any of the above embodiments, the side-access battery box 40 being mounted on the vehicle tube 62.

[0054] like Figure 3 and Figure 4 As shown, in another embodiment, the electric vehicle 60 includes a vehicle tube 62 and a direct-access battery box 50 as described in any of the above embodiments, the direct-access battery box 50 being mounted on the vehicle tube 62.

[0055] In another embodiment, the electric vehicle 60 includes a vehicle tube 62, a side-access battery box 40 as described in any of the above embodiments, and a direct-access battery box 50 as described in any of the above embodiments, both of which are mounted on the vehicle tube 62.

[0056] Compared with the prior art, the present invention has at least the following advantages: 1. In the side-mounted mode, i.e. in the scenario of side-rotation assembly and disassembly of the battery module 10, the battery module 10 is rotated clockwise around the rotating connection structure 210 so that the rotating connection structure 210 can be locked with the external rotating lock head 20, thereby realizing the side-rotation assembly of the battery module 10; conversely, the rotating connection structure 210 can be unlocked from the external rotating lock head 20, and the battery module 10 is rotated counterclockwise around the rotating connection structure 210, thereby realizing the side-rotation disassembly of the battery module 10. 2. In the direct-access mode, i.e., in the scenario of sliding assembly and disassembly of the battery module 10, the battery module 10 is slid in a straight line along the length extension direction of the sliding limit structure 110 towards the sliding lock head 30. Since the sliding connection structure 120 and the sliding limit structure 110 are located on the same side of the module body 100, the sliding limit structure 110 assists the module body 100 to slide into place along its own length extension direction and restricts longitudinal movement, so that the sliding connection structure 120 locks with the external sliding lock head 30, realizing the sliding assembly of the battery module 10; conversely, the sliding connection structure 120 is unlocked from the external sliding lock head 30, and the battery module 10 is slid in a straight line along the length extension direction of the sliding limit structure 110 away from the sliding lock head 30. The sliding limit structure 110 assists the module body 100 to slide along its own length extension direction, realizing the sliding disassembly of the battery module 10. 3. The battery module 10 described above can be used in both side-mounted and direct-mounted modes, eliminating the need to develop battery modules 10 with different structures, thus improving the adaptability of the battery module 10.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
