[0033] As shown in FIG. 1 to FIG. 4 , the present invention provides a frame structure, which includes a frame body, a saddle, and a saddle lock assembly.

[0034] Specifically, as shown in Figures 1 and 2, the frame body includes a first frame 1 and an extended frame 2, and the first frame 1 is detachably connected to the extended frame 2; the saddle includes a first saddle and a second saddle, and one of the first saddle and the second saddle is detachably connected to the frame body, and the length of the first saddle is smaller than the length of the second saddle; the saddle lock assembly includes a locking member and a lock buckle, the locking member is configured to be selectively installed on the first frame 1 or the extended frame 2, and the lock buckle is configured to be selectively installed on the first saddle or the second saddle, when the locking member is installed on the first frame 1, the first frame 1 is separated from the extended frame 2, and the lock buckle is installed on the first saddle, the locking member can be locked or opened with the lock buckle to lock or open the first frame 1 and the first saddle, when the locking member is installed on the extended frame 2, the first frame 1 is connected to the extended frame 2, and the lock buckle is installed on the second saddle, the locking member can be locked or opened with the lock buckle to lock or open the extended frame 2 and the second saddle. The length of the frame body can be changed by connecting and separating the first frame 1 and the extension frame 2, thereby adapting to saddles of different lengths, thereby improving the versatility of the frame body, reducing design investment, and lowering manufacturing costs.

[0035] Preferably, the frame structure further includes a lock plate 3, to which a locking member is mounted. The lock plate 3 is provided with a lock hole 311, through which a lock buckle can pass to connect with the lock member. The lock plate 3 can be mounted on the first frame 1 or the extended frame 2. Specifically, the lock hole 311 is provided in the middle of the lock plate 3, and fixing holes are provided on the periphery of the lock hole 311. Bolts pass through the fixing holes and the lock member to connect the lock member to the lock plate 3. In this embodiment, the lock hole 311 is cross-shaped. To ensure a stable connection between the locking member and the lock plate 3, the lock plate 3 is provided with two fixing holes, and the two fixing holes are arranged diagonally, which enables the locking member to be securely installed. Of course, in other embodiments, the shape of the lock hole 311 is determined by the shape of the lock buckle, and the number of fixing holes is determined according to actual needs.

[0036] Preferably, the extended frame 2 is provided with armrest mounting brackets 8 for mounting an armrest. Specifically, in this embodiment, three armrest mounting brackets 8 are welded to the extended frame 2, located on both sides and at the end of the extended frame 2. The armrest mounting brackets 8 mounted on both sides of the extended frame 2 are symmetrically distributed. The armrest is fixedly connected to all three armrest mounting brackets 8, making the armrest installation more secure and enhancing the safety of rear seat passengers. Of course, in other embodiments, the number and installation positions of the armrest mounting brackets 8 can be specifically set according to the frame structure.

[0037] Preferably, the first frame 1 is provided with a first mounting seat 4, which is configured to be selectively connected to the extended frame 2 or the lock plate 3; the extended frame 2 is also provided with a second mounting seat 5, and the lock plate 3 can be mounted on the second mounting seat 5. Specifically, the first mounting seat 4 is welded to the first frame 1 and is provided with a through hole. The first mounting seat 4 can be respectively mounted on the lock plate 3 or the extended frame 2. If the length of the first frame 1 meets the length requirement of the saddle, the lock plate 3 is mounted on the first mounting seat 4 by passing a bolt through the lock plate 3 and the through hole. If the length of the first frame 1 does not meet the length requirement of the saddle, the extended frame 2 is connected to the first mounting seat 4 by passing a bolt through the extended frame 2 and the through hole, so that the first frame 1 and the extended frame 2 together form the frame body. The second mounting seat 5 is also provided with a through hole. The lock plate 3 is mounted on the second mounting seat 5 by passing a bolt through the lock plate 3 and the through hole, so that the saddle can be smoothly mounted on the frame body.

[0038] Optionally, the extended frame 2 has a U-shaped structure, and the first frame 1 is symmetrically provided with two first mounting seats 4, with both sides of the open end of the extended frame 2 being detachably connected to the two first mounting seats 4. Specifically, since the first frame 1 has a bilaterally symmetrical structure, to ensure a stable connection between the first frame 1 and the extended frame 2, the two first mounting seats 4 are symmetrically welded on both sides of the first frame 1, and the extended frame 2 has a bilaterally symmetrical U-shaped structure. The two sides of the open end of the extended frame 2 are respectively connected to the two first mounting seats 4 by two bolts, thereby making the connection between the first frame 1 and the extended frame 2 more stable.

[0039] Optionally, the extended frame 2 is provided with two second mounting brackets 5, which are symmetrically arranged on the two sides of the extended frame 2, and the two ends of the lock plate 3 are detachably connected to the two second mounting brackets 5. In this embodiment, the two second mounting brackets 5 are respectively abutted against the two armrest mounting brackets 8 provided on both sides of the extended frame 2, and the second mounting brackets 5 are located at the end of the armrest mounting brackets 8 away from the first frame 1. In this way, the position of the second mounting brackets 5 can be directly determined based on the position of the armrest mounting brackets 8, and the symmetry of the two second mounting brackets 5 can be ensured, which reduces the work of determining the position of the second mounting brackets 5, shortens manufacturing time, and improves manufacturing efficiency.

[0040] Preferably, the first frame 1 is further provided with a shock-absorbing bracket 6, and the extended frame 2 is further provided with a connecting plate 7, with the shock-absorbing bracket 6 being detachably connected to the connecting plate 7. Specifically, to increase the connection strength between the first frame 1 and the extended frame 2 and to enhance the shock-absorbing effect of the extended frame 2, a connecting plate 7 is mounted on the bottom of the extended frame 2. The connecting plate 7 is detachably connected to the shock-absorbing bracket 6 on the first frame 1. This allows the extended frame 2 to have a shock-absorbing effect while increasing the number of connection points. This not only improves the strength of the main frame, but also enhances the comfort of the rear passengers.

[0041] Optionally, two shock-absorbing brackets 6 are symmetrically arranged on the left and right sides of the first frame 1, which can further improve the shock-absorbing effect of the frame body and enhance the user's riding experience; accordingly, connecting plates 7 are symmetrically installed on both sides of the extended frame 2, and the two connecting plates 7 are detachably connected to the two shock-absorbing brackets 6, respectively, to further improve the strength of the frame body and the comfort of the rear seat passengers.

[0042] Preferably, as shown in Figures 3 and 4, the lock plate 3 is provided with a first plane 31, and a lock hole 311 is provided on the first plane 31. Specifically, a cross-shaped lock hole 311 is provided at a position on the first plane 31 corresponding to the lock buckle of the saddle. The lock buckle passes through the lock hole 311 so that the bottom surface of the saddle abuts against the first plane 31, so that the first plane 31 supports the saddle.

[0043] Optionally, the lock plate 3 further comprises a second flat surface 32, which is lower than the first flat surface 31. The frame structure also includes a seat bucket, which is positioned below the saddle and mounted to the second flat surface 32. In this embodiment, the mounting member is a bolt, and the second flat surface 32 is provided with a mounting hole 321. The bolt passes through the seat bucket and the mounting hole 321 to connect the seat bucket to the second flat surface 32. The second flat surface 32 is lower than the first flat surface 31 to prevent the bolt cap from being exposed, which could affect the saddle's contact with the first flat surface 31 and thus undermine its stability. There are two second flat surfaces 32, one on either side of the first flat surface 31, and they support the edge of the seat bucket, ensuring a more stable installation. The connection between the first and second flat surfaces 31 and the edge of the extended frame 2 prevent the seat bucket from shifting. Of course, in other embodiments, the shape of the lock plate 3 is determined by the frame structure and connection structure. The mounting member may be a snap assembly that snaps the edge of the seat bucket into engagement with the second flat surface 32.

[0044] The present invention further provides an electric vehicle comprising a drive assembly and a wheel assembly, and also comprising the frame structure of any of the aforementioned embodiments, wherein the drive assembly and the wheel assembly are both mounted on the frame structure, the drive assembly being connected to the wheel assembly, and the drive assembly is configured to drive the wheel assembly for rotation. The electric vehicle also comprises other essential components of an electric vehicle in the prior art. In this embodiment, the specific type of the electric vehicle is not limited, and the electric vehicle may also be an electric motorcycle.

[0045] Furthermore, the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of the present invention.
