Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to a battery compression structure for electric vehicles. Background Art

[0002] As electric two-wheelers become more and more popular, the traditional way of compacting the lead-acid battery pack of electric two-wheelers is mostly to compact the battery from the top through a pressure strip.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0041] Refer to the following Figures 1 to 3 The electric vehicle battery compression structure described in the embodiments of the present application is described.

[0042] See also Figures 1 to 3As shown, an embodiment of the present application provides a battery clamping structure for an electric vehicle, which includes a fixing member 1, a battery 2, and a clamping device 3. The fixing member 1 is arranged at a designated position on the body of the electric vehicle, and the battery 2 and the clamping device 3 are both arranged on the fixing member 1. The fixing member 1 provides installation conditions for the battery 2 and the clamping device 3, and can also protect the battery 2 and the clamping device 3. The clamping device 3 includes a connecting assembly and a push-up member 302. The connecting assembly is arranged on the fixing device, and the push-up member 302 is connected to the connecting assembly. After the battery 2 is placed on the fixing member 1, the push-up member 302 can abut the battery 2 on the side of the battery 2, so that at least part of the other side wall 102 of the battery 2 can abut against the fixing member 1, so as to clamp the battery 2 between the fixing member 1 and the push-up member 302, thereby enhancing the stability of the battery 2 in the fixing member 1.

[0043] Specifically, the fixing member 1 includes a base plate 101 and side walls 102. The base plate 101 is disposed at the bottom of the side walls 102. The base plate 101 and the side walls 102 together enclose a storage space for accommodating the battery 2. Preferably, the side walls 102 include four side panels connected end to end to form an annular structure. Preferably, the base plate 101 and each side panel are provided with a hollow portion 103. The hollow portion 103 can dissipate heat to prevent heat generated by the battery 2 from accumulating and causing safety hazards.

[0044] Furthermore, in this embodiment, there are multiple batteries 2, and the multiple batteries 2 are arranged sequentially in the fixing component 1 along the first direction a. The multiple batteries 2 have the same structure, and two adjacent batteries 2 are attached to or arranged adjacent to each other. Each battery 2 avoids contact with the inner wall surface of the fixing component 1 except for the wall surface facing the adjacent battery 2, thereby ensuring the stability of the battery 2 in the fixing component 1 and preventing the battery 2 from moving around freely in the fixing component 1.

[0045] It should be noted that the first direction a is specifically the length direction of the fixing member 1, and the clamping device 3 is arranged on the inner wall surface of the fixing member 1. Preferably, the clamping device 3 is arranged on one or both of the two side plates of the fixing member 1 distributed along the first direction a. After the multiple batteries 2 are placed in the fixing member 1, the supporting member 302 can apply force to the first battery 2 or the last battery 2 along the first direction a, thereby enhancing the stability of the multiple batteries 2 in the fixing member 1.

[0046] It should be noted that the above is only a preferred embodiment. When there is a gap between the battery 2 and other side plates, a clamping device 3 can also be set on the inner wall surface of the other side plates of the fixing member 1, so as to abut each battery 2 in multiple directions, thereby clamping multiple batteries 2 in the fixing member 1.

[0047] Furthermore, the connecting component includes: a fixed plate 301 and a sliding component 303, wherein the fixed plate 301 is arranged on the inner wall surface of the fixed component 1. Preferably, the fixed plate 301 is a flat plate, and the length of the fixed plate 301 extends along the second direction b, and the second direction b is specifically the depth direction of the fixed component 1. The sliding component 303 is slidably connected to the fixed plate 301, and the top support member 302 is connected to the sliding component 303. As the sliding component 303 slides relative to the fixed plate 301 and changes position, the distance between the top support member 302 and the fixed plate 301 and the distance between the top support member 302 and the battery 2 both change, thereby adjusting the tightness of the contact of the top support member 302 with the battery 2.

[0048] The sliding assembly 303 specifically includes: a sliding rod 3031, a first swing arm 3032 and a second swing arm 3033, wherein the sliding rod 3031 is in the shape of a long strip, and is arranged on a side surface of the fixing plate 301 facing the inside of the fixing member 1. The length of the sliding rod 3031 extends along the depth direction of the fixing member 1. One end of the first swing arm 3032 is slidably connected to the sliding rod 3031, and the other end of the first swing arm 3032 is connected to the top member 302. One end of the swing arm 3033 is slidingly connected to the sliding rod 3031, and the other end of the second swing arm 3033 is connected to the supporting member 302, and the first swing arm 3032 and the second swing arm 3033 are set at an angle. As the positions of the first swing arm 3032 and the second swing arm 3033 relative to the sliding rod 3031 change, the angle between the first swing arm 3032 and the second swing arm 3033 also changes, thereby adjusting the size of the supporting force of the supporting member 302 on the battery 2.

[0049] The sliding assembly 303 further includes a first slider 3034 and a second slider 3035. Both the first slider 3034 and the second slider 3035 are sleeved on the sliding rod 3031, with the first slider 3034 positioned above the second slider 3035. One end of a first swing arm 3032 is hingedly connected to the first slider 3034, enabling the first swing arm 3032 to reciprocate along with the first slider 3034 on the sliding rod 3031. One end of a second swing arm 3033 is hingedly connected to the second slider 3035, enabling the second swing arm 3033 to reciprocate along with the second slider 3035 on the sliding rod 3031.

[0050] Furthermore, the top support member 302 is in the shape of a flat plate, and the end of the first swing arm 3032 away from the first slider 3034 is connected to the top support member 302, and the end of the second swing arm 3033 away from the second slider 3035 is connected to the top support member 302. The side surface of the top support member 302 away from the first swing arm 3032 and the second swing arm 3033 forms a top support surface, which can fit with the side of the battery 2, thereby applying a certain degree of abutment force to the battery 2.

[0051] Preferably, the top abutting surface is a plane, and more preferably, the top abutting surface is a smooth plane.

[0052] Furthermore, the clamping device 3 also includes a first locking member 304 and a second locking member (not shown). The first slider 3034 is provided with a first through-hole. The first locking member 304 can be specifically a bolt. The first locking member 304 can pass through the first through-hole and abut against the sliding rod 3031, thereby locking the first slider 3034 in its current position. The second slider 3035 is provided with a second through-hole. The second locking member can be specifically a bolt. The second locking member can pass through the second through-hole and abut against the sliding rod 3031, thereby locking the second slider 3035 in its current position. Preferably, the sliding rod 3031 is provided with a plurality of threaded grooves that can adapt to the first locking member 304 and the second locking member. The plurality of threaded grooves are evenly spaced along the length of the sliding rod 3031. The first locking member 304 and the second locking member can be connected to different threaded grooves, respectively, to enhance the locking effect of the first slider 3034 and the second slider 3035, thereby further enhancing the stability of the battery 2 within the fixing member 1.

[0053] To sum up, the electric vehicle battery clamping structure provided in the present application, by setting a clamping device 3 to apply force to other wall surfaces other than the connecting line of the battery 2, produces a clamping effect on the battery 2, which not only ensures the stability of the battery 2 in the fixed component 1, but also avoids wear on the connecting line or other connecting structures of the battery 2, affecting the safety of the electric vehicle.
