Description

Technical Field

[0001] This application relates to the field of transportation technology, and more specifically, to a seat height adjustment device and a vehicle. Background Technology

[0002] In modern transportation systems, electric vehicles and motorcycles, with their convenience and flexibility, have become important means of daily travel, widely used in urban commuting, short-distance travel, and other scenarios. As the user base continues to expand, the personalized needs of different users for vehicle comfort and safety are becoming increasingly prominent, and seat height, as a key factor affecting the riding experience, is gradually becoming a focus of industry attention.

[0003] Currently, the seat height adjustment technology for electric vehicles and motorcycles on the market has significant limitations. Fixed-height seat designs mean the seat height is predetermined during vehicle manufacturing and cannot be adjusted to suit the user's actual needs. For shorter users, an excessively high seat makes it difficult for their feet to reach the ground stably while riding, increasing the risk of tipping over due to lack of effective support during stops, starts, or low-speed riding, seriously threatening riding safety. For taller users, a fixed-height seat restricts legroom, easily leading to leg muscle fatigue and even affecting joint health during prolonged riding. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Please refer to Figure 1 and Figure 2 This embodiment provides a seat height adjustment device 100, including a frame, a mounting base 110 mounted on the frame, a plurality of height adjustment rods 120 and a pull plate 130 slidably mounted on the mounting base 110, the plurality of height adjustment rods 120 being distributed around the pull plate 130, a seat assembly 140 being connected to the height adjustment rods 120, the pull plate 130 sliding along the direction of travel of the electric vehicle, the height adjustment rods 120 sliding along the height direction of the electric vehicle, the height adjustment rods 120 being provided with a plurality of slots 121, and pulling the pull plate 130 causing any slot 121 on the pull plate 130 and the height adjustment rods 120 to switch between a locked state and a unlocked state.

[0030] When the seat height needs to be adjusted, pull the pull plate 130 to disengage it from the slot 121 on the height adjustment rod 120. At this time, the height adjustment rod 120 can slide freely along the height direction of the electric vehicle, allowing the user to adjust it to a suitable height according to their needs. After adjustment, push the pull plate 130 to re-engage it with the corresponding height slot 121 on the height adjustment rod 120, thereby fixing the seat assembly 140 at the adjusted height position, achieving convenient seat height adjustment.

[0031] By pulling the pull plate 130, the locking state of the slot 121 can be switched, thereby adjusting the seat height. The operation is simple and easy to understand, requiring no complicated tools, allowing users to quickly get started and adjust the seat height in a short time, improving ease of use. Multiple height adjustment rods 120 are distributed around the pull plate 130, jointly supporting the seat assembly 140. The locking and fixing of the pull plate 130 with the slots 121 on the height adjustment rods ensures that the seat remains stable in the adjusted height position. Even when encountering bumpy road conditions during vehicle operation, there will be no seat shaking or height change, effectively ensuring safety and stability during riding.

[0032] The seat height adjustment device 100 provided in this application includes a frame, a mounting base 110 mounted on the frame, multiple height adjustment rods 120 and a pull plate 130 slidably mounted on the mounting base 110, the multiple height adjustment rods 120 being distributed around the pull plate 130, and a seat assembly 140 being connected to the height adjustment rods 120. The pull plate 130 slides along the direction of travel of the electric vehicle, and the height adjustment rods 120 slide along the height direction of the electric vehicle. Multiple slots 121 are provided on the height adjustment rods 120. Pulling the pull plate 130 switches between a engaged state and an unengaged state between the pull plate 130 and any slot 121 on the height adjustment rods 120. This device can flexibly adjust the seat height according to the needs of users of different heights. For shorter users, the seat can be lowered to allow both feet to land stably, enhancing safety when stopping, starting, and riding at low speeds. For taller users, the seat can be raised to increase legroom, effectively relieving leg muscle fatigue caused by long-distance riding, protecting joint health, and greatly improving the comfort and usability of the vehicle.

[0033] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the edge of the pull plate 130 is provided with a protrusion 131 corresponding to the slot 121. Pulling the pull plate 130 causes the protrusion 131 to switch between a holding state and a releasing state with any slot 121 on the height lifting rod 120.

[0034] During actual adjustment, when the pull plate 130 is pulled, the protrusion 131 disengages from the slot 121 as the pull plate 130 moves, allowing the height adjustment rod 120 to slide freely along the height direction of the electric vehicle, thus adjusting the seat height. Once the desired height is reached, the pull plate 130 is released, and the protrusion 131, under the action of the reset mechanism, re-embeds into the corresponding height slot 121, thereby fixing the seat height. This method of using the protrusion 131 and slot 121 clearly defines the specific structural form of the engagement between the pull plate 130 and the height adjustment rod 120, making the engagement and disengagement process more stable and reliable. The precise correspondence between the protrusion 131 and slot 121 effectively prevents the seat from accidentally loosening due to vibration or other factors during riding, further enhancing the stability and safety of the seat height adjustment device. Simultaneously, this structural design is simple and intuitive, facilitating manufacturing and subsequent maintenance.

[0035] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As 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. Driving the pull block 133 moves the pull plate 130. In use, the user can directly pull the pull block 133, which transmits the pulling force to the pull plate 130 via the connecting rod 132, thus allowing the pull plate 130 to slide and switching the locking state of the slot 121 in the seat height adjustment device. The addition of the pull block 133 and connecting rod 132 provides the user with a convenient point of leverage, making seat height adjustment more effortless and convenient. Compared to directly pulling the pull plate 130, the pull block 133 increases the contact area between the user's hand and the adjustment component, improving operational comfort and convenience, and reducing operational difficulty.

[0036] In one possible embodiment of this application, such as Figure 1 and Figure 5 As shown, the seat assembly 140 includes a connecting plate 141, a support frame 142 and a seat 143 disposed on the connecting plate 141. The bottom of the seat 143 is provided with a cover 144 covering the mounting base 110 and the pull plate 130. An opening 1441 is provided on the cover 144, and the pull block 133 is partially exposed through the opening 1441.

[0037] In this structure, the cover 144 protects internal components such as the mounting base 110 and the pull plate 130, preventing dust and rainwater from entering and affecting their normal operation. The pull block 133 partially exposes the opening 1441, ensuring convenient operation for the user while also making the overall structure more compact and aesthetically pleasing. The coordinated design of the pull block 133 and the opening 1441 of the cover 144 ensures that the seat height adjustment device provides excellent protection without hindering normal user operation, achieving an organic combination of protection and operability, and improving the overall quality of the product.

[0038] In one possible embodiment of this application, such as Figure 3 As shown, a limiting member 111 is provided above the mounting base 110, and a pull plate 130 is sandwiched between the mounting base 110 and the limiting member 111, forming an active space for the pull plate 130 between the limiting member 111 and the mounting base 110.

[0039] Specifically, the presence of the limiting component 111 restricts the vertical movement of the pull plate 130, allowing it to slide only within the space formed between the mounting base 110 and the limiting component 111 along the direction of travel of the electric vehicle, thereby ensuring the stability and accuracy of the sliding of the pull plate 130. The setting of the limiting component 111 provides precise guidance and limitation for the sliding of the pull plate 130, preventing the pull plate 130 from deviating or wobbling during the sliding process, ensuring that the pull plate 130 can accurately engage and disengage with the slot 121 on the height adjustment rod 120, further improving the adjustment accuracy and reliability of the seat height adjustment device, and ensuring the stability and consistency of seat height adjustment.

[0040] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, there are four lifting rods, which are respectively located at the four corners of the mounting base 110, and four protrusions 131 are also provided accordingly. The four height lifting rods 120 are evenly distributed at the four corners of the mounting base 110, jointly supporting the seat assembly 140. At the same time, the four protrusions 131 respectively cooperate with the slots 121 on the four height lifting rods 120, so that a more uniform and stable adjustment and fixing effect can be achieved when adjusting the seat cushion height.

[0041] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an elastic reset member 150 is provided between the pull plate 130 and the mounting base 110. The two ends of the elastic reset member 150 are connected to the pull plate 130 and the mounting base 110 respectively. The elastic reset member 150 extends along the sliding direction of the pull plate 130 and provides a reset force to the pull plate 130. This reset force tends to keep the pull plate 130 in a locked state. When the pull plate 130 is pulled to release the locked state, the elastic reset member 150 is stretched or compressed, resulting in elastic deformation. After the pull plate 130 is released, the elastic reset member 150 returns to its original deformation, and the resulting reset force pushes the pull plate 130 back to its original position, causing it to re-lock with the slot 121 on the height lifting rod 120. 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 locked position, simplifying the operation process and improving adjustment efficiency. Meanwhile, 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 engaged with the slot 121 after adjustment, further enhancing the stability and reliability of the seat height adjustment device and effectively preventing the seat from accidentally loosening due to vibration and other factors during riding.

[0042] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting base 110 is provided with a mounting groove 112, and the elastic reset member 150 is disposed in the mounting groove 112. The design of the mounting groove 112 makes the installation of the elastic reset member 150 more standardized and stable, improves the working stability and reliability of the elastic reset member 150, and reduces the failure of the adjustment device caused by the displacement of the elastic reset member 150.

[0043] In one feasible embodiment of this application, as shown in 4, a sliding groove 113 is provided on the mounting base 110, and the connecting rod 132 slides on the sliding groove 113.

[0044] The slide groove 113 provides a guide track for the sliding of the connecting rod 132. When the user pulls the pull block 133, the connecting rod 132 slides in a specific direction within the slide groove 113, causing the pull plate 130 to slide synchronously, making the movement of the pull plate 130 more stable and accurate. The slide 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 adjustment, avoiding deviation or jamming, and making the seat height adjustment smoother and more precise.

[0045] This application also discloses a vehicle, including a vehicle body and the seat height adjustment device 100 from the foregoing embodiments. The vehicle can be a motorcycle or an electric vehicle, and it includes the same structure and beneficial effects as the seat height adjustment device 100 from the foregoing embodiments. The structure and beneficial effects of the seat height adjustment device 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
