Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a convenient assembly and disassembly structure, a power battery mounting rack, a frame assembly and an electric vehicle. Background Art

[0002] With the development of new energy sources and the growing adoption of eco-friendly travel concepts, two-wheeled vehicles (also known as electric vehicles) powered or assisted by power batteries have become an increasingly popular choice for transportation. However, two-wheeled vehicle frames are constructed of tubular materials, and battery loading and unloading space is very limited, making battery loading and unloading convenience a priority.

[0003] At present, most external power batteries on the market are installed and removed by direct insertion, and the direction of movement is basically in the same plane as the frame. When the battery is installed at the rear of the frame, it is easier to load and unload the battery; when the battery is installed in the middle of the frame, the loading and unloading space of the power battery is very limited due to the restrictions of the front and rear upper and lower tubes of the frame. In order to reliably install the battery in the middle of the frame and ensure convenient disassembly and assembly, traditional power battery mounting brackets, such as patent No. 202222571600.6, have proposed a rotating self-locking structure that facilitates battery disassembly and assembly. The fixed base and the rotating base are connected by equal-height screws, so that the rotating base rotates relative to the fixed base, and the rotation angle is limited by limiting holes and limiting columns. The battery bracket is connected to the rotating base, and the tube is connected to the fixed base, so that the battery bracket can rotate relative to the tube, so that the battery is installed in the middle of the frame and ensures convenient disassembly and assembly.

[0004] However, the rotating base and the fixed base of the conventional power battery mounting rack may shake up and down during relative rotation, which results in poor reliability of the rotating base rotating relative to the fixed base, and thus poor reliability of the conventional power battery mounting rack. Summary of the Invention

[0016] In one embodiment, the rotation guide column is provided in a fixing hole, and the mounting member is located in the fixing hole and is screwed to the rotation guide column.

[0017] In one embodiment, the diameter of the end of the mounting member facing away from the fixing bracket is greater than the width of the rotating slot.

[0018] In one embodiment, a pre-compression deformation gap exists between the fixed bracket and the rotating bracket.

[0041] The present application provides a convenient assembly and disassembly structure, including a fixed bracket, a rotating bracket, an elastic positioning column and an auxiliary limit member; the fixed bracket is provided with a first positioning hole and a second positioning hole; the rotating bracket can be rotatably connected to the fixed bracket, and the rotating bracket is formed with a rotating slot; the elastic positioning column is connected to the side of the rotating bracket facing the fixed bracket, and the elastic positioning column elastically supports and positions the first positioning hole or the second positioning hole; the auxiliary limit member is connected to the fixed bracket, the auxiliary limit member is passed through the rotating slot, and the auxiliary limit member is used to be located on the side of the rotating bracket away from the fixed bracket when the rotating bracket rotates relative to the fixed bracket.

[0042] The above-mentioned convenient assembly and disassembly structure is that the battery holder can be installed on the rotating holder, and the fixed holder can be fixed on the vehicle frame. When the power battery needs to be disassembled and assembled, since the rotating holder can be rotatably connected to the fixed holder, the rotating holder can be rotated to a predetermined angle relative to the fixed holder, so that the user can quickly disassemble or install the power battery on the battery holder, thereby realizing rapid disassembly and assembly of the power battery, especially for a vehicle frame with a relatively small space; the above-mentioned convenient assembly and disassembly structure, during the process of the rotating holder rotating relative to the fixed holder, is elastically supported and positioned in the first positioning hole or the second positioning hole by the elastic positioning column, so that the rotating holder is positioned in two different positions relative to the fixed holder, respectively, to meet the positioning requirements of the power battery with or without disassembly and assembly requirements; for example, when the elastic positioning column is elastically supported and positioned in the first positioning hole, the rotating holder is rotated out to the first predetermined position relative to the fixed holder, at which time the power battery can be disassembled and assembled; when the elastic positioning column is elastically supported and positioned in the When the cam is in the second positioning hole, the swivel bracket is rotated out to the second predetermined position relative to the fixed bracket.

In addition, the auxiliary limiting member is connected to the fixed bracket, and the auxiliary limiting member is inserted into the swivel slot. The auxiliary limiting member is located on the side of the swivel bracket away from the fixed bracket when the swivel bracket rotates relative to the fixed bracket, so that the swivel bracket can be prevented from shaking toward the side away from the fixed bracket during the rotation relative to the fixed bracket, thereby avoiding the situation in which the swivel base and the fixed base of the conventional power battery mounting bracket shake up and down during the relative rotation. The reliability of the rotation of the swivel base relative to the fixed base is better, thereby improving the reliability of the convenient assembly and disassembly structure.

[0043] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:

[0044] like Figures 1 to 2 As shown, the frame assembly 10 of one embodiment can be used for an electric vehicle or other electric equipment. The electric vehicle can be an electric two-wheeled vehicle, an electric three-wheeled vehicle, or an electric four-wheeled vehicle. In this embodiment, the electric two-wheeled vehicle can be an electric bicycle or an electric motorcycle.

[0045] like Figures 1 to 2 As shown, in one embodiment, the frame assembly 10 includes a power battery 100, a frame 200, and a power battery mounting bracket 300. The frame 200 is provided with a mounting portion 201, and the power battery mounting bracket 300 is mounted and fixed on the mounting portion 201. The frame 200 may be a triangular frame 200, a V-shaped frame 200, or other frame 200.

[0046] See also Figures 3 to 7 In one embodiment, the power battery mounting bracket 300 includes a battery bracket 310 and a convenient assembly and disassembly structure 320, and the battery bracket 310 is installed on the convenient assembly and disassembly structure 320. The convenient assembly and disassembly structure 320 includes a fixed bracket 321, a rotating bracket 323, an elastic positioning column 325 and an auxiliary limiter 327. The fixed bracket 321 is used to be connected to the vehicle frame 200. Specifically, the fixed bracket 321 is connected to the mounting portion 201. The fixed bracket 321 is provided with a first positioning hole 3211 and a second positioning hole 3213; the rotating bracket 323 is rotatably connected to the fixed bracket 321, and the rotating bracket 323 is formed with a rotating slot 3232. In this embodiment, the battery holder 310 is mounted on the rotating bracket 323. The battery holder 310 is removably connected to the power battery 100, allowing the power battery 100 to be connected to the rotating bracket 323 via the battery holder 310. At the same time, the power battery 100 can be removed from the battery holder 310, thereby improving the ease of use of the power battery mounting rack 300. Furthermore, the battery holder 310 has a nested structure, allowing the power battery 100 to be quickly removed and placed in the battery holder 310.

[0047] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown in one embodiment, the elastic positioning column 325 is connected to the side of the rotating bracket 323 facing the fixed bracket 321, and the elastic positioning column 325 is elastically pressed against and positioned in the first positioning hole 3211 or the second positioning hole 3213. Figure 2 and Figure 8 As shown, when the elastic positioning column 325 is elastically supported and positioned in the first positioning hole 3211, the rotating bracket 323 is rotated out to the first predetermined position relative to the fixed bracket 321. At this time, it is in a rotated open state, that is, the rotating bracket 323 and the fixed bracket 321 are at a predetermined angle relative to each other, and the power battery 100 can be disassembled and assembled. Especially for the vehicle frame 200 with a small space, the rotating bracket can be rotated out to meet the disassembly and assembly space of the power battery. Figure 1 and Figure 8 As shown, when the elastic positioning column 325 is elastically supported and positioned in the second positioning hole 3213, the rotating bracket 323 is rotated out to the second predetermined position relative to the fixed bracket 321. At this time, it is in a closed state, and the rotating bracket 323 is relatively parallel to the fixed bracket 321. The power battery 100 is reliably accommodated on the frame 200 along with the convenient assembly and disassembly structure 320.

[0048] like Figure 4As shown, in one embodiment, the auxiliary limit piece 327 is connected to the fixed bracket 321, the auxiliary limit piece 327 is inserted into the rotating slot 3232 and slides with the rotating bracket 323, and the auxiliary limit piece 327 is located on the side of the rotating bracket 323 away from the fixed bracket 321 when the rotating bracket 323 rotates relative to the fixed bracket 321, so that the rotating bracket 323 will not shake in the direction perpendicular to the plane where the rotating bracket 323 rotates during the rotation process relative to the fixed bracket 321, and at the same time, the auxiliary limit piece 327 slides along the rotating slot 3232 when the rotating bracket 323 rotates relative to the fixed bracket 321, thereby improving the stability and reliability of the rotation of the rotating bracket 323 relative to the fixed bracket 321.

[0049] The above-mentioned convenient assembly and disassembly structure 320, power battery mounting bracket 300 and frame assembly 10, battery bracket 310 can be installed on rotating bracket 323, fixed bracket 321 can be fixed on frame 200, when it is necessary to disassemble or assemble power battery 100, since rotating bracket 323 can be rotatably connected to fixed bracket 321, rotating bracket 323 can be rotated to a predetermined angle relative to fixed bracket 321, so that the user can quickly disassemble or install power battery 100 on battery bracket 310, and realize rapid disassembly and installation of power battery 100. The convenient assembly and disassembly structure 320 is particularly suitable for the frame 200 with a relatively small space. During the rotation of the rotating bracket 323 relative to the fixed bracket 321, the elastic positioning column 325 elastically supports and positions the rotating bracket 323 in the first positioning hole 3211 or the second positioning hole 3213, so that the rotating bracket 323 is positioned at two different positions relative to the fixed bracket 321, so as to meet the positioning requirements of the power battery 100 with or without the need for assembly and disassembly. During the rotation of the rotating bracket 323 relative to the fixed bracket 321, the rotating bracket 323 is positioned at two different positions relative to the fixed bracket 321. The cam 323 is pressed against the support member 321 so that the cam 323 can be rotated relative to the support member 321, thereby preventing the cam 323 from rocking when the cam 323 is in the unlocked position.

[0050] like Figures 3 to 5 As shown, further, the fixing bracket 321 is provided with a first mounting hole 302, and the mounting portion 201 is provided with a first screw hole 2012. The convenient assembly and disassembly structure 320 also includes a first screw 322, which is respectively passed through the first mounting hole 302 and the first screw hole 2012, and the first screw 322 is screwed to the frame 200, so that the fixing bracket 321 is reliably mounted on the frame 200.

[0051] like Figures 3 to 6 As shown, in one embodiment, the number of the auxiliary limit members 327 and the number of the rotating slots 3232 are both two, and the two auxiliary limit members 327 are arranged in a one-to-one correspondence at the two rotating slots 3232, and the second connecting holes 308 are respectively located between the two rotating slots 3232, so that the auxiliary limit members 327 can better slide along the rotating slots 3232 when the rotating bracket 323 rotates relative to the fixed bracket 321, and better avoid the problem of the rotating bracket 323 shaking up and down relative to the fixed bracket 321 during the rotation process relative to the fixed bracket 321, and further improve the stability and reliability of the rotation of the rotating bracket 323 relative to the fixed bracket 321.

[0052] like Figures 3 to 6 As shown, in one embodiment, the convenient assembly and disassembly structure 320 further includes a locking member 326. The fixed bracket 321 is formed with a first connection hole 306, and the rotating bracket 323 is formed with a second connection hole 308. The locking member 326 is respectively disposed in the first connection hole 306 and the second connection hole 308. The second connection hole 308 is aligned and connected to the first connection hole 306, so that the rotating bracket 323 can be rotatably connected to the fixed bracket 321. In this embodiment, the locking member 326 is a screw assembly or a bolt assembly.

[0053] like Figures 3 to 6As shown, further, the locking member 326 includes a locking screw 3262, a locking washer 3264 and a nut 3266. The locking screw 3262 is respectively inserted into the first connecting hole 306 and the second connecting hole 308. The head of the locking screw 3262 abuts against the side of the rotating bracket 323 away from the fixed bracket 321 through the locking washer 3264. The nut 3266 is sleeved on the rod of the locking screw 3262 and is threadedly connected to the locking screw 3262. The nut 3266 is limited to the side of the fixed bracket 321 away from the rotating bracket 323 to prevent the locking screw 3262 from rotating during the rotation of the rotating bracket 323 relative to the fixed bracket 321. That is, the problem of the nut 3266 being easily loosened from the locking screw 3262 during the rotation of the rotating bracket 323 relative to the fixed bracket 321 is avoided, so that the rotating bracket 323 and the fixed bracket 321 are reliably rotationally connected. Figure 4 and Figure 5 As shown, further, the rotating bracket 323 is formed with a first positioning groove 3231 that communicates with the second connecting hole 308. The locking washer 3264 is located in the first positioning groove 3231 and abuts against the locking washer 3264, so that the locking washer 3264 is better positioned and installed on the rotating bracket 323. Furthermore, the fixed bracket 321 is formed with a second positioning groove 3212 that communicates with the first connecting hole 306. The nut 3266 is located in the second positioning groove 3212 and is connected to the fixed bracket 321, so that the nut 3266 is better positioned and installed on the fixed bracket 321.

[0054] like Figures 3 to 6 As shown, in one embodiment, a pre-compression deformation gap 321a exists between the fixed bracket 321 and the rotating bracket 323. When the locking member 326 rotates and secures the rotating bracket 323 to the fixed bracket 321, the rotating bracket 323 can deform toward the pre-compression deformation gap 321a, further preventing the rotating bracket 323 from shaking relative to the fixed bracket 321, especially during the process of rotating the rotating bracket 323 rotating relative to the fixed bracket 321. In this embodiment, the pre-compression deformation gap 321a is offset from the position where the locking member 326 is secured to the rotating bracket 323, and the pre-compression deformation gap 321a is located on both sides of the locking member 326. Specifically, there are two auxiliary limit members 327, and the two auxiliary limit members 327 are located on both sides of the locking member 326. The pre-stressed deformation gap 321a is located between the fixed bracket 321 and the rotating bracket 323, and the pre-stressed deformation gap 321a is also located in the area between the locking member 326 and each auxiliary limit member 327, so that after the rotating bracket 323 is assembled to the fixed bracket 321, it can better deform toward the pre-stressed deformation gap 321a, and better avoid the rotating bracket 323 shaking up and down relative to the fixed bracket 321.

[0055] like Figure 4 and Figure 5 As shown, in one embodiment, a first support protrusion 321b and a second support protrusion 321c are provided on one side of the fixed bracket 321 adjacent to the rotating bracket 323. The first support protrusion 321b is arranged around the first connection hole 306, and the first positioning hole 3211 and the second positioning hole 3213 are both provided in the second support protrusion 321c. The pre-compression deformation gap 321a is formed between the fixed bracket 321, the rotating bracket 323, the first support protrusion 321b, and the second support protrusion 321c. This reduces the manufacturing difficulty of the pre-compression deformation gap 321a and simplifies the structure of the convenient assembly and disassembly structure 320. In this embodiment, the rotating bracket 323 is configured to deform into the pre-compression deformation gap 321a when the rotating bracket 323 is rotatably connected to the fixed bracket 321.

[0056] like Figure 2 、 Figure 3 and Figure 8 As shown, further, the rotating bracket 323 includes a bracket body 323a and a wear-resistant part 323b, the first support protrusion 321b and the second support protrusion 321c are both protruded from the bracket body 323a, and the second support protrusion 321c is plastic-wrapped in the wear-resistant part 323b, so that the wear-resistant part 323b is embedded in the second support protrusion, so that the wear-resistant part 323b is better fixedly connected to the second support protrusion 321c, and at the same time the structure of the rotating bracket 323 is more compact. The second mounting hole 303 and the second connection hole 308 are both provided in the bracket body 323a. The first positioning hole 3211 and the second positioning hole 3213 are also provided in the bracket body 323a. The wear-resistant member 323b is formed with a first through-hole 3238 and a second through-hole 3239. The first through-hole is connected to the first positioning hole 3211, and the second through-hole is connected to the second positioning hole 3213. This makes the rotating bracket 323 lightweight and low in manufacturing cost. At the same time, the first positioning hole 3211 and the second positioning hole 3213 have good wear resistance. In this embodiment, the wear-resistant member 323b is a hardware component. Furthermore, the wear-resistant member 323b is provided with an embedded rib 3235, which is embedded in the second support protrusion 321c.

[0057] like Figure 2 、 Figure 3 and Figure 6 As shown, further, the rotating slot 3232 is a waist-shaped slot, so that the auxiliary limiting member 327 can slide better along the rotating slot 3232 when the rotating bracket 323 rotates relative to the fixed bracket 321 .

[0058] like Figure 2 、 Figure 3 and Figure 7As shown, further, the elastic positioning post 325 elastically abuts and positions itself within the first positioning hole 3211 when the rotating bracket 323 rotates to a predetermined angle relative to the fixed bracket 321, placing the convenient assembly and disassembly structure 320 in a rotated open position. This allows for assembly and disassembly of the power battery 100 without being restricted by the bracket space, particularly in the confined space of the vehicle frame 200. In this embodiment, the predetermined angle is between 10° and 65°. In this embodiment, the predetermined angle is 30°.

[0059] like Figure 2 、 Figure 3 and Figure 6 As shown, in one embodiment, the auxiliary limiting member 327 includes a rotation guide column 3272 and a mounting member 3274, the rotation guide column 3272 is protruded on the side of the fixed bracket 321 adjacent to the rotation bracket 323, the rotation guide column 3272 is inserted into the rotation slot 3232 and slides relative to the rotation guide column 3272, the mounting member 3274 is connected to the rotation guide column 3272, and the mounting member 3274 is used to be located on the side of the rotation bracket 323 away from the fixed bracket 321 when the rotation bracket 323 rotates relative to the fixed bracket 321, so that the auxiliary limiting member 327 can reliably guide the rotation of the rotation bracket 323 relative to the fixed bracket 321, and at the same time, the auxiliary limiting member 327 can prevent the rotation bracket 323 from shaking during the rotation process relative to the fixed bracket 321.

[0060] like Figure 2 、 Figure 3 and Figure 6 As shown, in one embodiment, the mounting member 3274 is detachably connected to the rotating guide column 3272. In this embodiment, the rotating guide column 3272 defines a fixing hole, and the mounting member 3274 is positioned within the fixing hole and threadedly engaged with the rotating guide column 3272, enabling the mounting member 3274 to be detachably connected to the rotating guide column 3272. It will be appreciated that in other embodiments, the mounting member 3274 is not limited to being threadedly engaged with the rotating guide column 3272. For example, the mounting member 3274 may be snap-engaged with the rotating guide column 3272. Of course, in other embodiments, the mounting member 3274 is not limited to being detachably connected to the rotating guide column 3272. For example, the mounting member 3274 may be riveted or welded to the rotating guide column 3272.

[0061] like Figure 2 、 Figure 3 and Figure 6 As shown, further, the mounting member 3274 is a screw or a self-tapping washer screw. In this embodiment, the mounting member 3274 is a self-tapping washer screw, so that the mounting member 3274 has a better function of limiting the rotating bracket 323.

[0062] like Figure 2 、 Figure 4 and Figure 6 As shown, the rotating bracket 323 is further formed with an anti-sway limit groove 3234 connected to the rotating slide 3232. The end of the mounting member 3274 facing away from the fixed bracket 321 is located in the anti-sway limit groove 3234, and there is a gap between the end of the mounting member 3274 facing away from the fixed bracket 321 and the bottom of the anti-sway limit groove 3234, so that the rotating bracket 323 can slide smoothly along the limit groove when rotating relative to the fixed bracket 321. In this embodiment,

[0063] like Figure 3 、 Figure 4 and Figure 8 As shown, in one embodiment, the diameter value of the end of the mounting member 3274 that is away from the fixed bracket 321 is greater than the width value of the rotating groove 3232, so that the end of the mounting member 3274 that is away from the fixed bracket 321 can reliably prevent the rotating bracket 323 from shaking when the rotating bracket 323 rotates relative to the fixed bracket 321.

[0064] like Figure 4 、 Figure 6 and Figure 9 As shown, in one embodiment, the battery holder 310 is formed with a limiting flange 313 on the outer wall adjacent to the rotating bracket 323. The rotating bracket 323 is formed with a limiting groove 3236, that is, the rotating bracket 323 is formed with a groove-type skeleton structure. The limiting flange 313 is located in the limiting groove 3236, that is, the limiting flange 313 is embedded in the limiting groove 3236. Because the limiting flange 313 is located in the limiting groove 3236, the battery holder 310 is locked to the rotating bracket 323 through the fixing member 330, which can better deform and fit, thereby preventing the battery holder 310 from shaking relative to the rotating bracket 323, thereby better fixing the battery holder 310 to the rotating bracket 323.

[0065] like Figure 4 、 Figure 5 、 Figure 9 and Figure 10 As shown, the battery holder 310 further defines a second mounting hole 303, and the rotating bracket 323 defines a second screw hole 304. The convenient assembly and disassembly structure 320 also includes a second screw 324, which is respectively inserted into the second mounting hole 303 and the second screw hole 304 and is screwed to the rotating bracket 323, thereby securely attaching the battery holder 310 to the rotating bracket 323. In this embodiment, the second screw 324 is a screw or bolt, and the fixing hole is a threaded hole. Specifically, the second screw 324 is a machine-thread hexagonal screw.

[0066] like Figure 4and Figure 6 As shown, in one embodiment, a limiting boss 3237 is formed in the limiting groove 3236, and the limiting flange 313 is provided with a fixed limiting groove 3131. The limiting boss 3237 is located in the fixed limiting groove 3131 and is connected to the battery holder 310, thereby better preventing the battery holder 310 from shaking relative to the rotating bracket 323 and better fixing the battery holder 310 to the rotating bracket 323. In this embodiment, the limiting boss 3237 is a limiting frame, which provides the limiting boss 3237 with good supporting strength, avoids the problem of large deformation of the battery holder 310 when embedded in the limiting groove 3236, and further better fixes the battery holder 310 to the rotating bracket 323.

[0067] like Figures 1 to 6 As shown, the present application also provides an electric vehicle (not shown), comprising a frame assembly 10 of any of the above embodiments. Furthermore, the frame assembly 10 includes a power battery 100, a frame 200 and a power battery mounting bracket 300, the frame 200 is provided with a mounting portion 201, and the power battery mounting bracket 300 is mounted and fixed on the mounting portion 201. The power battery mounting bracket 300 includes a battery bracket 310 and a convenient assembly and disassembly structure 320, and the battery bracket 310 is mounted on the convenient assembly and disassembly structure 320. Among them, the convenient assembly and disassembly structure 320 includes a fixed bracket 321, a rotating bracket 323, an elastic positioning column 325 and an auxiliary limiter 327. The fixed bracket 321 is used to be connected to the frame 200. Specifically, the fixed bracket 321 is connected to the mounting portion 201. The fixed bracket 321 defines a first positioning hole 3211 and a second positioning hole 3213. The rotating bracket 323 is rotatably connected to the fixed bracket 321 and is formed with a rotating slot 3232. In this embodiment, the battery holder 310 is mounted on the rotating bracket 323. The battery holder 310 is detachably mounted on the power battery 100, allowing the power battery 100 to be connected to the rotating bracket 323 via the battery holder 310 and to be detachably mounted on the battery holder 310, thereby improving the ease of use of the power battery mounting bracket 300.

[0068] In one embodiment, an elastic positioning post 325 is connected to the side of the rotating bracket 323 facing the fixed bracket 321. The elastic positioning post 325 is elastically positioned against the first positioning hole 3211 or the second positioning hole 3213. When the elastic positioning post 325 is elastically positioned against the first positioning hole 3211, the rotating bracket 323 is rotated out to a first predetermined position relative to the fixed bracket 321. At this point, the rotating bracket 323 is in a rotated-open state, i.e., the rotating bracket 323 and the fixed bracket 321 are at a predetermined angle relative to each other, allowing for assembly and disassembly of the power battery 100, particularly in the confined space of the vehicle frame 200. When the elastic positioning post 325 is elastically positioned against the second positioning hole 3213, the rotating bracket 323 is rotated out to a second predetermined position relative to the fixed bracket 321. At this point, the rotating bracket 323 is in a closed state, parallel to the fixed bracket 321, and the power battery 100 is securely accommodated in the vehicle frame 200 with the convenient assembly and disassembly structure 320.

[0069] In one embodiment, the auxiliary limit member 327 is connected to the fixed bracket 321, and the auxiliary limit member 327 is inserted into the rotating slot 3232 and slides with the rotating bracket 323, and the auxiliary limit member 327 is located on the side of the rotating bracket 323 away from the fixed bracket 321 when the rotating bracket 323 rotates relative to the fixed bracket 321, so that the rotating bracket 323 will not shake in the direction perpendicular to the plane where the rotating bracket 323 rotates during the rotation process relative to the fixed bracket 321, and at the same time, the auxiliary limit member 327 slides along the rotating slot 3232 when the rotating bracket 323 rotates relative to the fixed bracket 321, thereby improving the stability and reliability of the rotation of the rotating bracket 323 relative to the fixed bracket 321.

[0070] The rotatable bracket 323 is rotatably connected to the fixed bracket 321, so that the rotatable bracket 323 can be rotated to a predetermined angle relative to the fixed bracket 321, so that the user can quickly remove or install the power battery 100 on the battery bracket 310, thereby realizing quick removal and installation of the power battery 100, especially for a frame 200 with a relatively small space. The convenient assembly and disassembly structure 320, during the rotation of the rotatable bracket 323 relative to the fixed bracket 321, is elastically supported and positioned in the first positioning hole 3211 or the second positioning hole 3213 by the elastic positioning column 325, so that the rotatable bracket 323 is positioned in two different positions relative to the fixed bracket 321, so as to meet the positioning requirements of the power battery 100 when it is required to be assembled or disassembled. When the rotatable bracket 323 rotates relative to the fixed bracket 321, the elastic positioning column 325 is elastically supported and positioned in the first positioning hole 3211 or the second positioning hole 3213, so that the rotatable bracket 323 is positioned in two different positions relative to the fixed bracket 321, so as to meet the positioning requirements of the power battery 100 when it is required to be assembled or disassembled. The cam 323 is fixed to the rear of the second support bracket 321 so that the cam 323 can be fixed to the rear of the second support bracket 321. The cam 323 is fixed to the rear of the second support bracket 321 so that the cam 323 can be fixed to the rear of the second support bracket 321.

[0071] Compared with the prior art, the present invention has at least the following advantages:

[0072] 1. The convenient assembly and disassembly structure 320 described above, wherein the battery holder 310 can be mounted on the rotating holder 323, and the fixed holder 321 can be fixed to the vehicle frame 200. When the power battery 100 needs to be assembled or disassembled, the rotating holder 323 can be rotatably connected to the fixed holder 321, so that the rotating holder 323 can be rotated to a predetermined angle relative to the fixed holder 321, so that the user can quickly remove or install the power battery 100 on the battery holder 310, thereby achieving rapid assembly and disassembly of the power battery 100, especially for vehicles with a relatively narrow space on the vehicle frame 200.

[0073] 2. The convenient assembly and disassembly structure 320 mentioned above, during the rotation of the rotatable bracket 323 relative to the fixed bracket 321, the elastic positioning column 325 elastically abuts and positions the rotatable bracket 323 in the first positioning hole 3211 or the second positioning hole 3213, so that the rotatable bracket 323 is positioned in two different positions relative to the fixed bracket 321, respectively, to meet the positioning requirements of the power battery 100 with or without the need for disassembly and assembly. For example, when the elastic positioning column 325 elastically abuts and positions the rotatable bracket 323 in the first positioning hole 3211, the rotatable bracket 323 is rotated out relative to the fixed bracket 321 to the first predetermined position, at which time the power battery 100 can be disassembled and assembled; when the elastic positioning column 325 elastically abuts and positions the rotatable bracket 323 in the second positioning hole 3213, the rotatable bracket 323 is rotated out relative to the fixed bracket 321 to the second predetermined position, at which time the power battery 100 is securely accommodated on the vehicle frame 200 along with the convenient assembly and disassembly structure 320.

[0074] When the cam 323 is in the unlocked position, the cam 323 is in the unlocked position, and the cam 323 is locked, so that the cam 323 can be unlocked and locked.
