Detailed Implementation

[0042] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0043] The following is for reference. Figures 1-21 Describes a seat side-sliding shielding structure according to an embodiment of the present utility model.

[0044] Some existing car seats are equipped with a side-sliding function, which slides the seat to one side to shorten the distance between seats in the same row, thereby making space on the other side for rear passengers to enter. However, the exposed track after the seat slides out not only affects the appearance but also makes it easy for foreign objects to fall in. Therefore, this utility model proposes a seat side-sliding shielding structure.

[0045] like Figures 1-2 As shown in the attached diagram, the first direction is the front-to-back direction of the vehicle, which is also the front-to-back direction of the seat, and the second direction is the left-to-right direction (width direction) of the vehicle, which is also the left-to-right direction of the seat.

[0046] like Figures 1-17As shown, the seat side sliding shielding structure 100 comprises a rotating shaft 1, a torsion spring 2, a winding pipe 3, a winding curtain 6 and a pre-tightening member 7. The torsion spring 2 is sleeved on the rotating shaft 1, and a first end of the torsion spring 2 is connected with a first end of the rotating shaft 1. The winding pipe 3 is sleeved on the torsion spring 2, a first end of the winding pipe 3 is sealed by a first sealing head 4, and a second end of the winding pipe 3 is sealed by a second sealing head 5, and a second end of the rotating shaft 1 is connected with the second sealing head 5. The winding curtain 6 is arranged around the winding pipe 3, one side of the winding curtain 6 is fixed to the winding pipe 3, and the other side of the winding curtain 6 is fixed to a seat. The pre-tightening member 7 is in rotating fit with the outer wall of the second sealing head 5, the second end of the rotating shaft 1 penetrates through the second sealing head 5 and extends into the pre-tightening member 7, the pre-tightening member 7 drives the rotating shaft 1 to rotate, and the rotating shaft 1 is pressed to move towards the first end of the winding pipe 3, and the rotating shaft 1 drives the torsion spring 2 to rotate to load a pre-tightening force.

[0047] Referring to Figures 5-18 As shown, the first end of the winding pipe 3 is sealed by the first sealing head 4, the second end of the winding pipe 3 is sealed by the second sealing head 5, and the rotating shaft 1 and the torsion spring 2 sleeved on the rotating shaft 1 are arranged in the winding pipe 3. The first end of the torsion spring 2 is connected with the first end of the rotating shaft 1, the second end of the torsion spring 2 is connected with the second sealing head 5, and the second end of the rotating shaft 1 penetrates through the second sealing head 5 and extends into the pre-tightening member 7. Figure 18 As shown, when the pre-tightening member 7 is pre-tightened, the rotating shaft 1 moves axially towards the first end of the winding pipe 3 and rotates simultaneously in the direction of increasing torsion force, so that the torsion spring 2 has a pre-tightening torque state in accordance with the preset, and at this time, the inner wall of the pre-tightening member 7 is in rotating fit with the outer wall of the second sealing head 5. When the pre-tightening member 7 is pre-tightened, the rotating shaft 1 is pressed to move axially towards the first end of the winding pipe 3, so that the torsion spring 2 is stretched and elongated, and thus the torsion spring 2 can quickly reach the required pre-tightening torque when the pre-tightening member 7 rotates in the direction of increasing torsion force.

[0048] Compared with the prior art in which one end of the torsion spring 2 is fixed and the other end is pre-tightened, the pre-tightening of the torsion spring 2 is achieved by means of the rotating shaft 1 in the present application, so that the torsion spring 2 cannot be deformed and arched in the winding pipe 3 during the pre-tightening process, the torsion spring 2 sleeved on the rotating shaft 1 can be uniformly deformed in the axial direction, so that the torsion spring 2 has a pre-tightening torque state in accordance with the preset, and thus the winding curtain 6 can have a stable winding state when it is unfolded or retracted with the seat.

[0049] In addition, the seat side sliding shielding structure 100 further comprises a locking member 8, which is detachably inserted on the pre-tightening member 7 and penetrates through the second sealing head 5 to be clamped into the second end of the rotating shaft 1, so as to lock the pre-tightening force of the torsion spring 2.

[0050] That is, when the pre-tightening piece 7 pre-tightens the torsion spring 2, the locking piece 8 is inserted on the pre-tightening piece 7 and clamped with the rotating shaft 1 through the second end cover 5, so as to lock the pre-tightening force of the torsion spring 2. In this way, the torsion force of the torsion spring 2 can be conveniently loaded when leaving the factory and locked by the locking piece 8 to ensure that the pipe 3 and the torsion spring 2 cannot rotate relative to each other, the uniform specification is convenient for factory transportation, and the pre-tightening force can be stored, so that the pre-tightening force does not need to be loaded additionally when assembling with the seat, and the installation is convenient.

[0051] Compared with the self-locking pre-tightening structure in the prior art, the pre-tightening piece 7 is pre-tightened, and the locking piece 8 is used to lock the pre-tightening force, which is simple to operate and convenient to assemble, can effectively reduce the pre-tightening failure risk, and is convenient for maintenance.

[0052] In this way, the pre-tightening force is locked by the locking piece 8 before the seat side sliding shielding structure 100 is assembled to the seat. When the seat side sliding shielding structure 100 is assembled with the seat, the pre-tightening piece 7 is connected with the seat, so that the pre-tightening force of the torsion spring 2 can be locked. At this time, the locking piece 8 can be removed from the pre-tightening piece 7.

[0053] According to the seat side sliding shielding structure 100 of the utility model, when the seat slides sideways, the corresponding end of the roller shutter 6 can be moved, and the pipe 3 can be rotated at the same time. At this time, the pipe 3 drives the second end of the torsion spring 2 to rotate to continue to increase the torsion force, so as to unfold the roller shutter 6, so that the roller shutter 6 is covered on the slide rail of the seat. When the seat is returned to the original position, the torsion force of the torsion spring 2 can drive the pipe 3 to rotate, so as to shrink the roller shutter 6. That is, the roller shutter 6 directly moves with the seat, and automatic unfolding or winding is realized. The overall structure is simple, and the operation is convenient.

[0054] The moving direction of the seat side sliding is consistent with the direction of increasing the torsion force, that is, the moving direction of the seat side sliding is the same as the direction of increasing the torsion force. In this way, on the basis of the pre-tightening force of the torsion spring 2 stored in the pipe 3, the torsion force of the torsion spring 2 can be continuously loaded through the seat side sliding. When the seat is returned to the original position, the torsion spring 2 can be better guaranteed to be automatically wound under the synergistic action of the pre-tightening force of the torsion spring 2 itself and the torsion force applied to the torsion spring 2 by the seat side sliding.

[0055] Referring to Figures 1-2 As shown in the figure, the seat includes a seat assembly 202 and a seat base 201. The seat assembly 202 slides in the left-right direction relative to the seat base 201 to realize seat side sliding. One side of the roller shutter 6 opposite to the other side is fixed to the seat base 201. The seat base 201 is provided with a seat slide rail 204. When the seat slides sideways, the pipe 3 slides with the seat assembly 202, so that the roller shutter 6 is unfolded.

[0056] Referring to Figures 3-4As shown, the seat also includes two mounting brackets 203. One mounting bracket 203 is connected to the first end cap 4, and the other mounting bracket 203 is fixedly connected to the pre-tensioning member 7. The first end cap 4 has a cylindrical protrusion 402, and the corresponding mounting bracket 203 has an opening. The cylindrical protrusion 402 is inserted into the opening to achieve the connection between the first end cap 4 and the mounting bracket 203.

[0057] Therefore, the seat side-sliding shielding structure 100 of this utility model, through the pre-tensioning member 7 driving the rotating shaft 1 to rotate, as the rotating shaft 1 moves axially towards the first end of the roller tube 3, it rotates synchronously in the direction of increasing torque, so that the torsion spring 2 reaches the preset pre-tensioning torque state. Specifically, by rotating the rotating shaft 1 to pre-tension the torsion spring 2, it is ensured that the torsion spring 2 will not deform or arch within the roller tube 3 during the pre-tensioning process, allowing the torsion spring 2 to deform uniformly along the axial direction, thereby ensuring that the roller blind 6 has a stable winding state when the seat unfolds or retracts. Furthermore, after the pre-tensioning member 7 pre-tensions the torsion spring 2, the pre-tensioning force is locked by the locking member 8, which is simple to operate, easy to assemble, effectively reduces the risk of pre-tensioning failure, and facilitates maintenance. In other words, the seat side-sliding shielding structure 100 of this utility model not only shields the seat slide rail 204 but also effectively prevents the locking structure from failing.

[0058] According to some embodiments of the present invention, the second end of the rotating shaft 1 is flattened to form a flat limiting part 101, and the inner wall of the pre-tightening member 7 is formed with a groove 701 adapted to the limiting part 101. The groove 701 and the limiting part 101 are interlocked to enable the pre-tightening member 7 to drive the rotating shaft 1 to rotate.

[0059] Reference Figure 5 , Figures 9-12 As shown, the second end of the rotating shaft 1 forms a flat limiting part 101, and the inner wall of the pretensioner 7 forms a groove 701, so that the second end of the rotating shaft 1 passes through the second end cap 5 and extends into the groove 701, so that the limiting part 101 and the groove 701 are locked together. In this way, when the rotating pretensioner 7 rotates in the direction of increasing torque, the rotating shaft 1 can rotate synchronously, thereby applying pretension force to the torsion spring 2.

[0060] According to some embodiments of the present invention, a first pre-tightening hole 702 is formed on the pre-tightening member 7, a second pre-tightening hole 501 is formed on the second end of the rotating shaft 1, and a third pre-tightening hole 102 is formed on the second end of the rotating shaft 1. The locking member 8 passes through the first pre-tightening hole 702 and the second pre-tightening hole 501 in sequence and then gets stuck in the third pre-tightening hole 102.

[0061] Reference Figures 8-12 As shown, the locking member 8 passes through the first pre-tightening hole 702 on the pre-tightening member 7 and the second pre-tightening hole 501 on the second end cap 5 in sequence, and then gets into the third pre-tightening hole 102 at the second end of the rotating shaft 1, thereby locking the pre-tightening force.

[0062] In the example of the utility model, the pre-tightening member 7 can be a pre-tightening clasp 902. Alternatively, the pre-tightening member 7 can also be a pre-tightening bolt.

[0063] According to some embodiments of the utility model, the outer wall of the pre-tightening member 7 is provided with at least two mounting ears 703, mounting holes 704 are formed on the mounting ears 703 and are adapted to be connected to the seat through the mounting holes 704.

The pre-tightening member 7 can be rotated through the two mounting ears 703, which facilitates pre-tightening. That is, the mounting ears 703 not only can be connected to the seat, but also can improve the operational convenience of rotating the pre-tightening member 7.

[0065] According to some embodiments of the utility model, the first end of the rotating shaft 1 is formed with a slot 103, the slot 103 extends axially to the end of the rotating shaft 1, and the first end of the torsion spring 2 is inserted into the slot 103.

In addition, the limiting assembly 9 further comprises a felt ring 903 assembled between the snap spring 902 and the limiting cover 901, which can play a buffering role.
