Description

Technical Field

[0001] This utility model relates to the field of components of electric tricycles, and specifically to an adjustable electric tricycle seat device. Background Technology

[0002] An electric tricycle is a three-wheeled transport vehicle powered by a battery and driven by a motor, used for hauling goods or people. Electric tricycles use tubular, high-capacity, left and right-side-lined, deep-discharge, traction-type batteries, capable of withstanding continuous discharge for extended periods. Under normal use, the battery capacity remains unchanged for two years. The electric tricycle motor is a DC series-wound brushed or brushless traction motor with an internal speed-regulating and power-boosting device, ensuring strong output power and preventing damage under normal use.

[0003] The seat is an important component of the driver's cab of an electric tricycle. The common seat structure of electric tricycles in the current technology is fixed. Since the body shape of the operators is different, the solid seat structure cannot meet the comfort needs of some operators, and it will also cause inconvenience in operation. Utility Model Content

Detailed Implementation

[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention. Example 1:

[0017] The adjustable electric tricycle seat device proposed in this embodiment includes a frame body 1, and further includes two components: a sliding adjustment component and a clamping and limiting component 3. The sliding adjustment component includes a positioning plate 4 with a predetermined working length and supporting force; a sliding plate 5 slidably connected to the positioning plate 4 and having a predetermined working length; the clamping and limiting component 3 includes a connecting plate 301 connected to the sliding plate 5 and having a predetermined working length and supporting force; and a limiting clamping unit connected to the connecting plate 301, having a predetermined working length, and capable of adjusting within a predetermined range; the working surface of the sliding plate 5 is provided with a seat cushion 2 of a predetermined working size. During subsequent operations, the sliding adjustment of the sliding plate 5 can drive the seat cushion 2 to adjust to the corresponding working position. The limiting clamping unit includes three components: a limiting shell 302, a positioning rod 303, and a linkage part. The limiting shell 302 is placed on the working surface of the connecting plate 301, is hollow and has a predetermined supporting force, and is provided with multiple open through holes for corresponding limiting and connection operations. The positioning rod 303 passes through the through hole provided in the limiting shell 302, has a predetermined working length and supporting force, and can be adjusted within a predetermined range. The linkage part is movably connected to the positioning rod 303, has a predetermined working size and supporting force, and can be adjusted within a predetermined range. During subsequent operations, the linkage part can be adjusted to the corresponding working state by adjusting the positioning rod 303. The linkage part includes four components: a linkage block 304, a linkage plate 305, a limiting plate 306, and a clamping linkage unit. The linkage block 304 is slidably connected to the working surface of the connecting plate 301, connected to the positioning rod 303, has a predetermined working size, and maintains a predetermined working distance from the limiting shell 302. One end of the linkage plate 305 is rotatably connected to the linkage block 304, has a predetermined working size and supporting force, and can be adjusted within a predetermined range. One end of the limiting plate 306 is hinged to the linkage plate 305, and the other end is hinged to the limiting shell 302. It has a predetermined bending radius and supporting force, allowing for adjustment within a predetermined range. The clamping linkage unit is connected to the linkage plate 305, has a predetermined working size and supporting force, and can adjust its working state according to the rotation of the linkage plate 305. During later operations, the position adjustment of the linkage block 304 causes the linkage plate 305 to rotate accordingly, and the limiting plate 306 can adjust its working angle accordingly, following the rotation of the linkage plate 305. Example 2:

[0018] Based on Embodiment 1, the clamping linkage unit comprises two components: a clamping arm 307 and a support plate 308. The clamping arm 307 is connected to the linkage plate 305 and maintains a predetermined working distance from the limiting plate 306, allowing it to adjust its working state according to the rotation of the linkage plate 305. One end of the support plate 308 is movably connected to the linkage plate 305, and the other end is movably connected to the clamping arm 307. It has a predetermined working length and supporting force, enabling corresponding connection and limiting operations. During later operations, the rotation of the linkage plate 305 causes the clamping arm 307 to perform corresponding linkage adjustments. Simultaneously, the support plate 308 can limit the clamping arm 307 during the linkage process, increasing its stability. The working surface of the clamping arm 307 is serrated, and there are multiple clamping arms 307. Multiple linkage plates 305, limiting plates 306, and support plates 308 are symmetrically distributed. In a further preferred embodiment, the positioning plate 4 is provided with corresponding outwardly expanding edges to facilitate the clamping arm 307 in performing corresponding clamping and limiting operations. The working surface of the clamping arm 307 is serrated, and there are multiple clamping arms 307. There are multiple linkage plates 305, limiting plates 306, and support plates 308, which are symmetrically distributed.

[0019] Based on the above embodiments, the working process of this utility model is as follows: When it is necessary to adjust the seat cushion 2, simply press the positioning rod 303 downward in the working direction, thereby causing the linkage block 304 to slide downward. Since one end of the limiting plate 306 is connected to the limiting shell 302, one end of the linkage plate 305 is lifted, thereby causing the clamping arm 307 to open. Then, slide the sliding plate 5 to adjust the seat cushion 2 as a whole to adjust its position accordingly. When the adjustment is completed to the corresponding position, lift the positioning rod 303 upward in the working direction again, and the linkage block 304 is lifted upward, thereby causing the linkage block 304 to slide upward and lift the other end of the linkage plate 305, so that the clamping arm 307 clamps and fixes the seat cushion 2 in the direction close to the positioning plate 4, thereby fixing the seat cushion 2 again.

[0020] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
