Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile seat angle adjuster, specifically is an automobile seat angle adjuster with self locking performance. BACKGROUND

[0002] The automobile seat angle adjuster is a key component for adjusting the angle of the seat back on the automobile seat. The component shown in the figure is likely to be part of the automobile seat angle adjuster. It is mainly composed of a shell, a gear, a locking mechanism, etc. Its role is very important. On the one hand, it can meet the individual needs of different drivers and passengers for seat comfort. When driving long distances or resting, it can be adjusted to a comfortable posture to reduce fatigue. On the other hand, in the event of an emergency such as a collision, the appropriate seat back angle helps the restraint system such as the seat belt to work better, ensuring the safety of the driver and passengers.

[0003] In the actual use of the automobile seat angle adjuster, the traditional automobile seat angle adjuster has serious hidden dangers in fixing the angle of the seat. When the vehicle is driving, due to road bumps or sudden braking, the seat may accidentally slide or change angle due to the looseness of the angle adjuster. This not only interferes with the normal operation of the driver and distracts his attention, but also may cause the driver to be unable to maintain the best driving posture in an emergency, increasing the risk of accidents; when adjusting the angle of the seat, the operation is often not smooth and accurate. Some angle adjusters require a lot of force to adjust the angle, which is difficult for passengers with less strength. Moreover, it is difficult to accurately adjust the seat to the desired angle, and often requires repeated adjustment, wasting time and effort. CONTENT OF THE UTILITY MODEL

[0013] Compared with the prior art, this utility model provides a car seat adjuster with self-locking function, which has the following beneficial effects:

[0014] 1. This self-locking car seat adjuster features a self-locking mechanism where the tips of the locking teeth are triangular with one side angled. These teeth engage with the outer rings of the front and rear chucks. When a single chuck engages with a locking tooth, the chuck can only rotate in the direction of the tooth's angle, creating a self-locking effect against rotation in the other direction. Because the angles of the front and rear locking teeth are opposite, the locking direction and the rotatable direction are opposite during use. When both the front and rear locking teeth are engaged with the outer rings of the chucks, the chucks cannot rotate at all, achieving complete locking of the seat back connecting plate. When the operator needs to move the seat back connecting plate, they only need to control one side of the locking teeth to retract inward into the fixed box. Simultaneously, while the seat back connecting plate is being moved, it can also be locked in the opposite direction, preventing the seat back connecting plate from swinging backward during rotation and ensuring the stability of the device during use.

[0015] 2. This self-locking car seat adjuster, through a positioning mechanism, causes the slide cylinder two to move to the left under the action of the return spring. When the paddle is turned down, the paddle can automatically engage with the sleeve to complete the positioning of the teeth. This eliminates the need to keep the paddle pressed down when adjusting the seat back connecting plate, reducing the difficulty of operation and making it simple and convenient for staff to use.

[0031] Furthermore: When it is necessary to rotate the chair back connecting plate 4 clockwise, the operator only needs to move the rear paddle 1303 downward to retract the rear locking tooth 1204 into the fixing box 1201. When it is necessary to rotate the chair back connecting plate 4 counterclockwise, the operator only needs to move the front paddle 1303 downward to retract the locking tooth 1204 into the fixing box 1201. The operation is simple and convenient for the operator to use.

[0032] Example 2

[0033] See Figure 1 , Figure 2 , Figure 4 and Figure 6 Furthermore, based on Embodiment 1, the positioning mechanism 2 includes a reset component 21 and a positioning component 22, with the reset component 21 located to the right of the self-locking component 12 and the positioning component 22 located to the left of the reset component 21.

[0034] The reset assembly 21 includes a fixed cylinder 2101, which is located on the right side of the fixed box 1201. The fixed cylinder 2101 is fixedly connected to the front and rear sides of the seat connecting plate 3. A second slide cylinder 2102 is slidably connected inside the fixed cylinder 2101. A reset spring 2103 is fixedly connected inside the right side of the second slide cylinder 2102. A lever 2104 is fixedly connected to the bottom of the second slide cylinder 2102. The lever 2104 is slidably connected inside the bottom of the fixed cylinder 2101. The positioning assembly 22 includes a locking rod 2201, which is fixedly connected to the left side of the second slide cylinder 2102. A sleeve 2202 is sleeved around the outer ring of the locking rod 2201. The sleeve 2202 is fixedly connected to the right side of the outer side of the sleeve plate 1302.

[0035] Furthermore: Under the action of the return spring 2103, the slide cylinder 2102 drives the locking rod 2201 to move to the left on its own. When the lever 1303 is pushed down, the locking rod 2201 can automatically engage with the sleeve 2202 to complete the positioning of the locking tooth 1204. This eliminates the need to keep the lever 1303 pressed down when moving the chair back connecting plate 4, reducing the difficulty of operation and making the operation simple and convenient for staff to use.

[0036] In actual operation, when this device is used and it is necessary to rotate the chair back connecting plate 4 clockwise, the operator first moves the rear lever 2104 to the right. The movement of lever 2104 to the right drives the sliding cylinder 2102 to move the locking lever 2201 to the right. Then, the operator presses down the rear lever 1303. The downward movement of the rear lever 1303 drives the rear sliding cylinder 1202 to move downward through the sleeve plate 1302 and the moving sliding rod 1301. The downward movement of the rear sliding cylinder 1202 drives... The rear locking tooth 1204 moves downward and retracts into the fixed box 1201. Then, the operator releases the limit on the rear lever 2104. At this time, the slide cylinder 2102, under the action of the return spring 2103, drives the locking lever 2201 to move to the left and engage with the sleeve 2202. This locks the position of the rear locking tooth 1204 in the fixed box 1201. Then, the operator can directly rotate the chair back connecting plate 4 clockwise. The rotation of the chair back connecting plate 4 drives the chuck 1101 to rotate clockwise through the locking shaft 41. 1101 rotates clockwise, pressing the inclined surface of the front retaining tooth 1204 and causing it to retract downwards. Then, retaining tooth 1204 aligns with another groove on the outer ring of the chuck 1101. The slide cylinder 1202, under the action of the compression spring 1203, drives retaining tooth 1204 upwards to engage with the outer ring of the chuck 1101. At this time, the retaining springs 42 on both sides, moving in opposite directions, simultaneously apply resistance to the rotation of the backrest connecting plate 4 through the retaining shaft 41 and the seat connecting plate 3. When the operator moves the backrest connecting plate 4, they can adjust the position of retaining tooth 1204 according to the direction of the groove. 04 When the force is applied and the device pops out and engages, a series of jerks are felt. After the chair back connecting plate 4 is rotated to the appropriate angle, the operator moves the rear lever 2104 to the right, causing the locking lever 2201 to retract into the fixed cylinder 2101 and release the positioning of the sleeve 2202. At this time, the rear locking tooth 1204 can automatically engage with the outer ring of the chuck 1101 again under the action of the slide cylinder 1202 and the compression spring 1203. At this time, the chuck 1101 is completely locked again, and the angle adjustment of the chair back connecting plate 4 is completed.

[0037] Similarly, when it is necessary to rotate the chair back connecting plate 4 counterclockwise, the operator only needs to control the front locking teeth 1204 to retract downward into the fixing box 1201 and then rotate the chair back connecting plate 4 counterclockwise.
