[0020] See also Figure 1-4The utility model provides an embodiment: a breathable vehicle seat base, including a base body 1. In this embodiment, the base body 1 is a hollow rectangular block structure, and its front end surface is an arc-shaped structure to improve the riding comfort. In order to improve its strength, a reinforcement portion can be provided on its surface. When in use, it is necessary to cover the outer side of the base body 1 with a flexible material. Four mounting holes 8 are provided at the edge of the base body 1 to facilitate installation and fixation with the seat armrest. A clearance through hole 2 is provided through the base body 1. In this embodiment, a retaining edge is provided at the edge of the clearance through hole 2 as an integral vertical bend. A fixing plate 3 is horizontally arranged inside the through hole 2, and a plurality of first ventilation holes 301 are evenly spaced and penetrated on the fixing plate 3. The first ventilation holes 301 are specifically rectangular through holes, which are convenient for air flow. A movable baffle 6 for closing and shielding the first ventilation holes 301 is arranged at the bottom end of the fixing plate 3, and a plurality of second ventilation holes 601 are penetrated on the movable baffle 6. The second ventilation holes 601 and the first ventilation holes 301 have the same size. The second ventilation holes 601 and the first ventilation holes 301 are overlapped and separated to realize the ventilation of the base. The movable baffle 6 is The elastic support member 7 is slidably arranged at one end of the fixed plate 3. In order to improve the stability of the movable baffle 6, the movable baffle 6 and the fixed plate 3 can be arranged to be connected by a slide rail and a slide groove. The elastic support member 7 is used to push the second ventilation hole 601 to overlap with the first ventilation hole 301. The elastic support member 7 includes a guide rod 701 fixed inside the make way through hole 2 along the width direction of the make way through hole 2 and a support spring 702 sleeved on the guide rod 701. A top plate 602 is fixed at one end of the movable baffle 6, and a through hole matching the guide rod 701 is penetrated on the top plate 602. One end of the support spring 702 is in contact with the inner wall of the clearance hole 2, the other end of the support spring 702 is in contact with the top plate 602, and the end of the movable baffle 6 away from the top plate 602 is in contact with the other side of the clearance hole 2. The movable baffle 6 slides along the length direction of the guide rod 701 to improve its stability. The support spring 702 is not easy to deform. In the normal state, under the elastic support of the support spring 702, the second ventilation hole 601 and the first ventilation hole 301 are in a coincidence state, and the seat has good air permeability. At the same time, the fixed plate 3 and the movable baffle 6 can improve the strength of the base body 1;

[0021] There are two elastic support members 7, and the two elastic support members 7 are respectively arranged on both sides of the inner side of the yielding through hole 2, so as to further improve the stability of the movement of the movable baffle 6;

[0022] A connecting rope 5 is fixed on the movable baffle 6, and a winding mechanism 4 for winding the connecting rope 5 is provided on the base body 1. The winding mechanism 4 includes a winding drum 401 rotatably connected to the side wall of the yielding through hole 2 and a fixed seat 402 fixed to the front end of the outer wall of the base body 1, which is specifically arranged below the movable baffle 6, and a through hole is penetrated in the middle of the fixed seat 402 to accommodate the free rotation of the winding drum 401. One end of the connecting rope 5 is fixedly connected to the movable baffle 6, and the other end is fixedly connected to the winding drum 401. One end of the winding drum 401 extends to the outside of the base body 1 through the through hole. The interior of the winding drum 401 is movably provided with a driving inner tube 403 through a reset spring 405. One end of the driving inner tube 403 extends to the outside of the winding drum 401 and is fixed with a limiting plate 404. The fixed seat 40 2 is provided with a positioning groove 4021 that matches the limit plate 404, and the return spring 405 is used to push the limit plate 404 to move to the side close to the fixed seat 402. Specifically, the end of the driving inner tube 403 close to the limit plate 404 is penetrated by a strip through hole, and the end of the winding drum 401 is penetrated by a through hole that matches the end of the driving inner tube 403. One end of the return spring 405 abuts against the inner side wall of the strip through hole, and the other end abuts against the inner side wall of the winding drum 401. When in use, the fixed seat 402 is located outside the seat. When adjustment is required, it is only necessary to rotate the winding drum 401 to pull the movable baffle 6 to move. When the winding drum 401 is rotated in the opposite direction, the movable baffle 6 is reset under the elastic support of the elastic support member 7. The operation is convenient and quick, and can meet different usage requirements.

[0023] Working principle: When in use, under the elastic support of the support spring 702, one end of the movable baffle 6 abuts against one side of the inner side of the yielding through hole 2, and the second ventilation hole 601 and the first ventilation hole 301 overlap each other, which can quickly conduct the heat of the seat and have good air permeability. When the weather is relatively cold, the limit plate 404 is directly pulled outward to drive the inner tube 403 to compress the return spring 405. After the limit plate 404 is moved out to the outside of the positioning groove 4021, the limit plate 404 is rotated to drive the inner tube 403 and the winding drum 401 to rotate, and the connecting rope 5 is wound around the winding drum. On 401, the length of the connecting rope 5 becomes shorter, and the other end pulls the movable baffle 6 to slide along the guide rod 701, and the top plate 602 compresses the supporting spring 702, causing the movable baffle 6 to slide relative to the fixed plate 3. The adjustment is completed when the first ventilation hole 301 and the second ventilation hole 601 are misaligned, and then the angle of the limit plate 404 is adjusted so that it is facing the positioning groove 4021 and then released. The reset spring 405 pushes the limit plate 404 and the driving inner tube 403 to move synchronously to the side close to the fixed seat 402, and the limit plate 404 is inserted into the positioning groove 4021 to complete the fixation.
