[0031] Referring to Figures 1-5 The electric seat lock bolt with a damping structure comprises a base 1, a driving assembly 2, a moving block 3 and a damping assembly 4.

[0032] The moving block 3 is in sliding connection with the base 1, the driving assembly 2 is connected with the moving block 3, and the damping assembly 4 is connected with the moving block 3.

[0033] When the driving assembly 2 drives the moving block 3 to move to the limit position, the damping assembly 4 abuts against the base 1, and the moving block 3 is tightly fitted with the driving assembly 2 and / or the moving block 3 is tightly fitted with the base 1.

[0034] Compared with the prior art, the electric seat movement in the prior art does not increase the damping assembly 4 to slow down the impact force when the electric seat moves to the limit position, and the various parts of the seat are in close connection at the beginning and do not produce a large abnormal sound, only the abnormal sound when the seat hits occurs, and when the connection of the parts is partially loose after being used for a period of time, the impact force when the seat moves to the limit position causes the parts to collide, and the abnormal sound increases. The moving block 3 of the utility model first contacts the base 1 through the damping assembly 4 to make the parts more tightly fitted, and the damping assembly 4 can also bear the impact force of the seat, prolonging the service life of other parts of the seat. After a long period of work, only the damping assembly 4 needs to be replaced to continue to use, reducing the cost investment.

[0035] In the optimization, the driving assembly 2 comprises a driving member 21 and a driving rod 22.

[0036] The driving member 21 is connected with the driving rod 22 and cooperates with each other to drive the moving block 3.

[0037] The base 1 can be provided with side plates on both sides for contacting the damping assembly 4. When the driving member 21 is a motor and the driving rod 22 is a screw rod, the screw rod and the motor can be threadedly connected, the screw rod and the motor cooperate with each other to drive the moving block 3 to rotate, a limiting member for limiting the rotation of the moving block 3 is arranged around the moving block 3, the moving block 3 moves along the axis of the screw rod through the cooperation of the limiting member, the screw rod and the motor, the moving block 3 moves towards the side plate, the damping assembly 4 first contacts the side plate, the moving block 3 is tightly fitted with the driving assembly 2 and / or the moving block 3 is tightly fitted with the base 1, thereby reducing the abnormal sound caused by the collision between the moving block 3 and the base 1; when the driving member 21 is an electric push rod driver, the driving rod 22 and the driver can be connected through interference, the driving rod 22 and the moving block 3 are connected through gluing or welding, the electric push rod driver drives the driving rod 22 to push or pull the moving block 3, the moving block 3 moves, the damping assembly 4 first contacts the side plate, the moving block 3 is tightly fitted with the driving assembly 2 and / or the moving block 3 is tightly fitted with the base 1, thereby reducing the abnormal sound caused by the collision between the moving block 3 and the seat.

[0038] In the optimization, the damping assembly 4 is at least two and is connected with the moving block 3.

[0039] The plurality of damping assemblies 4 can be symmetrically arranged on both sides of the moving block 3, which provides more balanced support force than a single damping assembly 4, effectively reduces the deviation and shaking of the moving block 3 during sliding, ensures smooth movement, prolongs the service life, and improves the stability and reliability of the overall structure.

[0040] In the optimization, the damping assembly 4 comprises a contacting member 41, a containing member 42 and a buffering member 43.

[0041] The receiving member 42 is mounted on the moving block 3, and the abutting member 41 is inserted into the receiving member 42, with the end of the abutting member 41 protruding from the receiving member 42 for abutting the base 1; the buffer member 43 provides a buffering force between the receiving member 42 and the abutting member 41, and the abutting member 41 moves in the receiving member 42 and cooperates with the buffer member 43 to provide a tight fit between the moving block 3 and the drive assembly 2 and / or to provide a tight fit between the moving block 3 and the base 1.

[0042] The receiving member 42 allows the abutment member 41 to slide smoothly. Both ends of the abutment member 41 abut against the base 1, forming an effective buffer. When the moving block 3 is driven by the driving member 21 to begin moving, the abutment member 41 first abuts against the base 1. The abutment member 41 then moves away from the abutting end within the receiving member 42, abutting against the moving block 3. As the moving block 3 moves, the force exerted by the abutment member 41 on the moving block 3 gradually increases, thus making the connection between the moving block 3 and the driving rod 22 tighter. When the moving block 3 moves to its limit position, the tight fit between the moving block 3 and the drive rod 22 ensures that the moving block 3 does not produce significant abnormal noise when it comes into contact with the base 1. Similarly, the seat has other components. The contact member 41 first contacts the side plate of the base 1. The contact member 41 moves away from the contact, and the force applied to the moving block 3 by the buffer member 43 and / or the receiving member 42 is gradually increased, making the moving block 3 fit more tightly with the other components, reducing the gaps between the moving block 3 and the other components, thereby reducing abnormal noise.

[0043] In the optimization, the abutting member 41 is provided with a protrusion 412, and the receiving member 42 is provided with a through groove 421 for receiving the protrusion 412;

[0044] The protrusion 412 and the through groove 421 cooperate to limit the movement of the contacting member 41.

[0045] The protrusion 412 of the abutment 41 and the through groove 421 cooperate with each other to ensure that the abutment 41 moves within a fixed range. The protrusion 412 and the through groove 421 can also adjust the moving distance of the abutment 41 and change the compression degree of the buffer 43, thereby changing the buffering effect and improving the stability and comfort of the seat.

[0046] In the optimization, the protrusion 412 is provided with a slope, which is used for the protrusion 412 to insert into or restrict its disengagement from the through slot 421.

[0047] When the contact member 41 moves toward the insertion end, the protrusion 412 gradually enters the through groove 421, forming a stable limiting structure, effectively preventing the contact member 41 from excessive displacement, ensuring its smooth operation within a predetermined range, and further improving the overall stability and durability of the damping assembly 4. When the contact member 41 moves away from the insertion end, the protrusion 412 restricts the contact member 41 from disengaging from the through groove 421, preventing it from falling off. At the same time, the contact area between the contact member 41 and the side plate increases, dispersing the impact force and extending the service life.

[0048] In the optimization, at least one through groove 421 is provided, and multiple through grooves 421 are circumferentially staggered on the side wall of the receiving member 42.

[0049] Multiple through slots 421 can increase the connection between the abutting member 41 and the receiving member 42, making it less likely to shake in the receiving member 42. The multiple through slots 421 are not on the same horizontal line, ensuring that the connection part of the receiving member 42 is reduced due to the setting of multiple through slots 421, thus avoiding excessive impact force and deformation.

[0050] In the optimization, the contacting part 41 includes a connecting part 411;

[0051] The protrusion 412 is fixedly connected to the connector 411, and the connector 411 can deform in the direction of the protrusion 412 disengaging from the through groove 421.

[0052] The connector 411 is made of a flexible material, such as plastic. When the abutment 41 is inserted into the receiver 42, the connector 411 causes the protrusion 412 to bend inward, allowing the abutment 41 to smoothly enter the receiver 42. When the abutment 41 needs to be removed from the receiver 42, the connector 411 is manually bent to remove the abutment 41 smoothly. The flexibility of the connector 411 not only facilitates installation and disassembly but also enhances the adaptability of the component. The design of the connector 411 increases the installation stability and convenience of the abutment 41 and the receiver 42.

[0053] During the optimization, two contact elements 41 are set;

[0054] The buffer 43 is located inside the receiving member 42. Each end of the receiving member 42 is inserted with an abutment 41. The end of the abutment 41 exposed outside the receiving member 42 is used to abut against the base 1. The two ends of the buffer 43 are respectively connected to the corresponding abutment 41.

[0055] The buffer 43 can be fixedly connected to the contact 41 by adhesive bonding or welding, or the buffer 43 abuts against the contact 41, with one of the contact 41 abutting against the base 1 and moving away from the contact end. The contacting contact 41 drives the non-contacting contact 41 to move through the buffer 43. The protrusion 412 of the non-contacting contact 41 abuts against the groove, restricting the movement of the non-contacting contact 41. Thus, the buffer 43 cooperates with the contacting contact 41 to absorb kinetic energy and generate deformation. The buffer 43 releases potential energy and drives the contacting contact 41 to reset. By gradually increasing the force, the connection between the moving block 3 and the drive rod 22 becomes tighter, reducing the gap between the moving block 3 and other components, and effectively reducing the impact noise of the seat at the extreme position.

[0056] In the optimization, the abutment 41 is set to one, and the buffer 43 is set to two;

[0057] The length of the abutment 41 is at least greater than the length of the receiving member 42. The abutment 41 is inserted into the receiving member 42. Two buffer members 43 are respectively disposed on both sides of the receiving member 42. One end of the buffer member 43 is connected to one end of the abutment 41, and the other end is connected to one end of the receiving member 42 on the same side. Both ends of the abutment 41 are used to abut against the base 1.

[0058] The length of the abutting member 41 is greater than the length of the receiving member 42. The abutting member 41 is always partially exposed outside the receiving member 42. This exposed part abuts against the base 1. One end of the abutting member 41 abuts against the base 1, thereby moving away from the abutting end. The abutting end cooperates with the receiving member 42 to compress the buffer member 43, gradually applying the force of the moving block 3, thereby making the moving block 3 and the other components fit more tightly. The individual abutting member 41 moves in the receiving member 42. Since both ends abut against the receiving member 42, it has good stability and is not easy to shake.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
