DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figure 1-6A cushion for an electric vehicle that is easy to adjust comprises a base 1, a cushion body 2 is arranged on the upper end surface of the base 1, support vertical rods 3 are symmetrically slidably connected to the top of the base 1, a same connecting rod 4 is fixedly installed on the top of the two support vertical rods 3, a lateral adjustment component 100 is installed on the connecting rod 4, the interior of the base 1 is hollow, and a longitudinal adjustment component 200 is installed inside the base 1.

[0030] The longitudinal adjustment assembly 200 includes a rack 201 fixedly installed on the inner sides of the two supporting vertical rods 3. A rotating rod 202 is rotatably connected to one side of the base 1. A driven gear 203 is fixedly installed on the middle outer surface of the rotating rod 202. A rotating rod 204 is rotatably connected to one side of the rotating rod 202. A driving gear 205 is fixedly installed on the middle outer surface of the rotating rod 204. One end of the rotating rod 204 passes through the outside of the base 1 through a bearing and is fixedly installed with a ratchet 206. A transmission rod 207 is fixedly installed at one end of the ratchet 206. A handle 208 is rotatably connected to one end of the transmission rod 207. A pawl 209 is rotatably connected to one side of the base 1. A connecting plate 210 is fixedly installed on the top of the pawl 209 on one side of the base 1. A spring 211 is fixedly installed at the bottom of the connecting plate 210. A pressing plate 212 is fixedly installed on one side of the pawl 209. The inner bottom wall of the base 1 is fixedly installed with vertical plates 213 on both symmetrical sides of the two supporting vertical rods 3, and a T-shaped sliding block 214 is fixedly installed on one side of the top of several vertical plates 213. T-shaped sliding grooves 215 are opened on both symmetrical sides of the two supporting vertical rods 3. The longitudinal adjustment component 200 provided can effectively adjust the height of the seat cushion body 2. When the height of the seat cushion body 2 needs to be adjusted, the driving gear 205 on the rotating rod 204 is driven to rotate by rotating the handle 208 counterclockwise. Because the driving gear 205 and the driven gear 203 are meshed and connected, the driving gear 205 and the driven gear 203 are meshed and connected with the corresponding rack 201, thereby driving the two supporting vertical rods 3 to move upward to a suitable height, and then through the elastic action of the spring 211, the pawl 209 is driven to block the ratchet 206, thereby fixing the adjusted height, thereby adjusting the height of the seat cushion body 2.

[0031] Embodiment 2:

[0032] See also Figure 1-6This embodiment provides a technical solution based on the first embodiment: the lateral adjustment component 100 includes a fixed block 101 fixedly installed at the bottom of the seat cushion body 2, a sliding groove 102 is opened at the top of the connecting rod 4, and a threaded rod 103 is rotatably connected to the inner wall of the sliding groove 102. One end of the threaded rod 103 passes through the outside of the connecting rod 4 through a bearing and is fixedly installed with a rotating handle 104. The seat cushion body 2 can be effectively adjusted laterally by the set lateral adjustment component 100. When the seat cushion body 2 needs to be adjusted laterally, the threaded rod 103 is driven to rotate by rotating the rotating handle 104. While the threaded rod 103 rotates, the thread pushes the fixed block 101 to move in the sliding groove 102, thereby driving the seat cushion body 2 to move laterally.

[0033] The driving gear 205 is meshed with the driven gear 203, and the driven gear 203 and the driving gear 205 are meshed with the corresponding rack 201. When the ratchet 206 rotates counterclockwise, the pawl 209 passes through the ratchet 206 and can rotate freely. When the ratchet 206 rotates clockwise, the pawl 209 blocks the ratchet 206 so that it cannot rotate. The bottom of the spring 211 is fixedly installed on the top of the pawl 209. The spring 211 drives the pawl 209 to always contact the ratchet 206. The T-shaped slider 214 matches the T-shaped slide groove 215. A protective cover 5 is fixedly installed on one side of the outer side of the base 1 outside the ratchet 206 and the pawl 209. The outer side of the protective cover 5 is rotatably connected to the door panel 6 through a hinge. The door panel 6 is clamped on one side of the protective cover 5. The fixed block 101 is threadedly connected to the outer surface of the threaded rod 103. The fixed block 101 matches the sliding groove 102. The bottom of the seat cushion body 2 fits with the top of the connecting rod 4.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] Working principle: When the height of the seat cushion body 2 needs to be adjusted, the handle 208 is rotated counterclockwise to drive the driving gear 205 on the rotating rod 204 to rotate. Since the driving gear 205 and the driven gear 203 are meshed and connected, the driven gear 203 is driven to rotate. Since the driven gear 203 and the driving gear 205 are meshed and connected with the corresponding rack 201, the two supporting vertical rods 3 are driven to move upward to a suitable height. Then, through the elastic action of the spring 211, the pawl 209 is driven to block the ratchet 206, so that the adjusted height is fixed, thereby adjusting the height of the seat cushion body 2. When the seat cushion body 2 needs to be lowered, the pressing plate 212 is pressed with The movable pawl 209 is separated from the ratchet 206, and then the handle 208 is rotated along the pointer to drive the two supporting vertical rods 3 to be lowered and adjusted. After adjusting to the appropriate height, the pressing plate 212 is released, and then the pawl 209 drives the pawl 209 to block the ratchet 206 through the elastic action of the spring 211, thereby fixing the adjusted height. When it is necessary to adjust the distance between the seat cushion body 2 and the handle of the electric vehicle, the threaded rod 103 is driven to rotate by rotating the rotating handle 104. While the threaded rod 103 rotates, the thread pushes the fixed block 101 to move in the sliding groove 102, thereby driving the seat cushion body 2 to move laterally, thereby adjusting the seat cushion body 2 laterally, and the applicability is strong.
