[0002] In the modern transportation system, electric vehicles and motorcycles have become important means of transportation for people's daily travel due to their convenience and flexibility, and are widely used in various scenarios such as urban commuting and short trips. With the continuous expansion of the user group, the personalized needs of different users for vehicle comfort and safety have become increasingly prominent. As a key factor affecting the riding experience, the seat height has gradually become the focus of the industry.
[0003] At present, there are significant limitations in the seat height adjustment technology of electric vehicles and motorcycles on the market. With the fixed-height seat design, the height of such seats is determined during vehicle production and cannot be adjusted according to the actual needs of users.

[0029] Please refer to Figure 1 and Figure 2 , this embodiment provides a seat height adjustment device 100, including a vehicle frame, a mounting seat 110 provided on the vehicle frame, a plurality of height lifting rods 120 and a pull plate 130 slidably provided on the mounting seat 110. The plurality of height lifting rods 120 are distributed around the pull plate 130. A seat assembly 140 is connected to the height lifting rods 120. The pull plate 130 slides along the running direction of the electric vehicle, the height lifting rods 120 slide along the height direction of the electric vehicle, and a plurality of card slots 121 are provided on the height lifting rods 120. The pull plate 130 is pulled to switch the pull plate 130 and any one of the card slots 121 on the height lifting rods 120 between a clamped state and an unclamped state.
[0030] When the seat cushion height needs to be adjusted, pull the pull plate 130 to release the locking state between the pull plate 130 and the card slot 121 on the height lifting rod 120. At this time, the height lifting rod 120 can slide freely along the height direction of the electric vehicle, and the user can adjust the height lifting rod 120 to a suitable height according to their own needs. After the adjustment is completed, push the pull plate 130 to make the pull plate 130 and the card slot 121 at the corresponding height on the height lifting rod 120 lock again, so as to fix the seat assembly 140 at the adjusted height position and realize the convenient adjustment of the seat cushion height.
[0031] By pulling the pull plate 130, the switching of the locking state of the card slot 121 can be realized, and then the adjustment of the seat cushion height can be completed. The operation process is simple and easy to understand, without the need to use complex tools. Users can quickly get started and complete the adjustment of the seat cushion height in a short time, improving the convenience of use. A plurality of height lifting rods 120 are distributed around the pull plate 130 to jointly support the seat assembly 140. And through the locking and fixing of the pull plate 130 and the card slot 121 on the height lifting rod 120, it can ensure that the seat cushion remains stable at the adjusted height position. Even when encountering bumpy road conditions during vehicle driving, the seat cushion will not shake or change height, effectively ensuring the safety and stability during the riding process.
[0032] The seat cushion height adjustment device 100 provided in this application includes a vehicle frame, a mounting seat 110 provided on the vehicle frame, a plurality of height lifting rods 120 and a pull plate 130 slidably arranged on the mounting seat 110. The plurality of height lifting rods 120 are distributed around the pull plate 130. A seat assembly 140 is connected to the height lifting rod 120. The pull plate 130 slides along the driving direction of the electric vehicle, and the height lifting rod 120 slides along the height direction of the electric vehicle. A plurality of card slots 121 are provided on the height lifting rod 120. Pull the pull plate 130 to switch the pull plate 130 and any card slot 121 on the height lifting rod 120 between the locking state and the unlocked state. This device can flexibly adjust the seat cushion height according to the needs of users of different heights. For users with shorter heights, the seat cushion can be lowered so that both feet can land stably, enhancing safety during parking, starting, and low-speed driving; for users with taller heights, the seat cushion can be raised to increase the leg space, effectively relieving the leg muscle fatigue caused by long-term riding and protecting joint health, greatly improving the comfort and applicability of the vehicle.
[0033] In a feasible embodiment of this application, as Figure 1 and Figure 2 shown, a convex block 131 corresponding to the card slot 121 is provided on the edge of the pull plate 130. Pull the pull plate 130 to switch the convex block 131 and any card slot 121 on the height lifting rod 120 between the locking state and the unlocked state.
[0034] During the actual adjustment process, when the pull plate 130 is pulled, the convex block 131 will disengage from the card slot 121 as the pull plate 130 moves, enabling the height lift rod 120 to slide freely along the height direction of the electric vehicle to achieve the adjustment of the seat height; when the appropriate height is adjusted, the pull plate 130 is released, and the convex block 131 is re-embedded into the corresponding height card slot 121 under the action of the reset mechanism, thereby fixing the seat height. This way of matching the convex block 131 with the card slot 121 clarifies the specific structural form of the clamping between the pull plate 130 and the height lift rod 120, making the process of clamping and releasing the clamp more stable and reliable. The precise correspondence between the convex block 131 and the card slot 121 can effectively prevent the seat from loosening accidentally due to vibrations and other factors during riding, further enhancing the stability and safety of the seat height adjustment device; at the same time, this structural design is simple and intuitive, facilitating production manufacturing and later maintenance.
[0035] In a feasible embodiment of the present application, as Figure 1 , Figure 2 and Figure 3 shown, a connecting rod 132 is connected to the pull plate 130, and a pull block 133 is provided at the end of the connecting rod 132. The pull plate 130 is driven by driving the pull block 133. During use, the user can directly pull the pull block 133, and transmit the pulling force to the pull plate 130 through the connecting rod 132, thereby realizing the sliding of the pull plate 130 and completing the switching of the clamping state of the card slot 121 in the seat height adjustment device. The addition of the pull block 133 and the connecting rod 132 provides a convenient operating force point for the user, making it more labor-saving and convenient for the user to adjust the seat height. Compared with directly pulling the pull plate 130, the setting of the pull block 133 increases the contact area between the user's hand and the adjustment component, improves the comfort and convenience of the operation, and reduces the operation difficulty.
[0036] In a feasible embodiment of the present application, as Figure 1 and Figure 5 shown, the seat assembly 140 includes a connecting plate 141, a support frame 142 and a seat 143 provided on the connecting plate 141. A cover shell 144 covering the mounting seat 110 and the pull plate 130 is provided at the bottom of the seat 143. An opening 1441 is provided on the cover shell 144, and a part of the pull block 133 is exposed from the opening 1441.
[0037] In this structure, the housing 144 can protect internal components such as the mounting base 110 and the pulling plate 130, preventing dust, rainwater, etc. from entering and affecting the normal operation of the components. And a part of the pulling block 133 is exposed from the opening 1441, which not only ensures that the user can conveniently operate the pulling block 133, but also makes the overall structure more compact and beautiful. The cooperative design of the pulling block 133 and the opening 1441 of the housing 144 enables the seat cushion height adjustment device to have good protection performance without affecting the normal operation of the user, achieving an organic combination of protection and operability and improving the overall quality of the product.
[0038] In a feasible embodiment of the present application, as Figure 3 shown, a limiting member 111 is provided above the mounting base 110, the pulling plate 130 is clamped between the mounting base 110 and the limiting member 111, and a moving space for the pulling plate 130 is formed between the limiting member 111 and the mounting base 110.
[0039] Specifically, the presence of the limiting member 111 restricts the movement of the pulling plate 130 in the vertical direction, enabling it to slide only along the driving direction of the electric vehicle within the moving space formed between the mounting base 110 and the limiting member 111, thereby ensuring the stability and accuracy of the sliding of the pulling plate 130. The setting of the limiting member 111 provides precise guidance and limitation for the sliding of the pulling plate 130, avoiding situations such as deviation and shaking of the pulling plate 130 during the sliding process, ensuring that the pulling plate 130 can accurately engage and disengage with the card slot 121 on the height lifting rod 120, further improving the adjustment accuracy and reliability of the seat cushion height adjustment device, and guaranteeing the stability and consistency of the seat cushion height adjustment.
[0040] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, there are four lifting rods, and the four lifting rods are respectively arranged at the four corners of the mounting base 110, and the convex blocks 131 are also correspondingly arranged in four. The four height lifting rods 120 are evenly distributed at the four corners of the mounting base 110 to jointly support the seat assembly 140. At the same time, the four convex blocks 131 respectively cooperate with the card slots 121 on the four height lifting rods 120, and when adjusting the seat cushion height, a more uniform and stable adjustment and fixing effect can be achieved.
[0041] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, an elastic reset member 150 is provided between the pull plate 130 and the mounting seat 110. The two ends of the elastic reset member 150 are respectively connected to the pull plate 130 and the mounting seat 110. The elastic reset member 150 extends along the sliding direction of the pull plate 130. The elastic reset member 150 is used to provide a reset force to the pull plate 130, and the reset force has a tendency to keep the pull plate 130 in a clamped state. When the pull plate 130 is pulled to release the clamped state, the elastic reset member 150 is stretched or compressed to generate elastic deformation; after the pull plate 130 is released, the elastic reset member 150 recovers its deformation, and the generated reset force pushes the pull plate 130 to reset, so that it is re-clamped with the card slot 121 on the height lifting rod 120. The setting of the elastic reset member 150 provides a reliable power source for the reset of the pull plate 130, eliminating the need for the user to manually push the pull plate 130 back to the clamped position, simplifying the operation process and improving the adjustment efficiency. At the same time, the elastic reset member 150 can continuously maintain the reset force on the pull plate 130, ensuring that the pull plate 130 can be tightly clamped with the card slot 121 after the adjustment is completed, further enhancing the stability and reliability of the seat height adjustment device, and effectively preventing the seat from accidentally loosening due to factors such as vibration during riding.
[0042] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a mounting groove 112 is provided on the mounting seat 110, and the elastic reset member 150 is arranged in the mounting groove 112. The design of the mounting groove 112 makes the installation of the elastic reset member 150 more regular and stable, improving the working stability and reliability of the elastic reset member 150, and reducing the adjustment device failure caused by the displacement of the elastic reset member 150.
[0043] In a feasible embodiment of the present application, as shown in Figure 4, a sliding groove 113 is provided on the mounting seat 110, and the connecting rod 132 slides on the sliding groove 113.
[0044] The sliding groove 113 provides a guiding track for the sliding of the connecting rod 132. When the user pulls the pull block 133, the connecting rod 132 slides in the sliding groove 113 along a specific direction, driving the pull plate 130 to slide synchronously, making the movement of the pull plate 130 more stable and accurate. The setting of the sliding groove 113 provides precise guidance for the sliding of the connecting rod 132, ensuring that the pull plate 130 can slide smoothly along the predetermined direction during the adjustment process, avoiding deviation or jamming, and making the seat height adjustment smoother and more accurate.
[0045] The embodiment of the present application also discloses a vehicle, including a vehicle body and the seat height adjusting device 100 in the foregoing embodiment. The vehicle can be a motorcycle or an electric vehicle, and the vehicle has the same structure and beneficial effects as the seat height adjusting device 100 in the foregoing embodiment. The structure and beneficial effects of the seat height adjusting device 100 have been described in detail in the foregoing embodiment and will not be repeated here.
[0046] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
