[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides an electric seat slide rail, which can solve the technical problem in the related art that when an occupant encounters a collision or sudden braking in a zero-gravity sitting position, the occupant's spine and the seat will be relatively squeezed, which may easily cause spinal compression and pose a major safety hazard.

[0032] See also Figure 1 As shown, an electric seat slide rail provided in an embodiment of the present application may include: at least two slide rails 11, at least two of the slide rails 11 are parallel to each other, and the slide rails 11 are used to connect seats. It should be understood that a fixed rail 12 can be fixed on the floor of the vehicle, and the slide rail 11 can be slidably installed on the fixed rail 12; a connecting bracket 2, the connecting bracket 2 is fixed between at least two of the slide rails 11, that is, one end of the connecting bracket 2 is fixed to one of the slide rails 11, and the other end is fixed to the other slide rail 11; a driving shaft 31, the driving shaft 31 is installed on the connecting bracket 2, and the driving shaft 31 is connected to at least two of the slide rails 11; a buffer mechanism 4, the buffer mechanism 4 is fixed to the connecting bracket 2, and the buffer mechanism 4 is connected to the driving shaft 31. In the first state, the buffer mechanism 4 and the driving shaft 31 are relatively fixed. In the second state, the buffer mechanism 4 drives the driving shaft 31 to rotate, so that the sliding rail 11 slides.

[0033] The embodiment of the present application fixes the buffer mechanism 4 connected to the drive shaft 31 on the connecting bracket 2. It should be understood that two fixed rails 12 parallel to each other can be set on the floor of the vehicle, and two sliding rails 11 are also set accordingly. The two ends of the connecting bracket 2 can be fixed on the two sliding rails 11 respectively, so that when the position of the sliding rail 11 is adjusted, the seat fixed on the top of the sliding rail 11 can move more smoothly. In the first state, the buffer mechanism 4 is relatively fixed to the drive shaft, that is, the buffer mechanism 4 does not affect the rotation or stillness of the drive shaft, and in the second state, the second state may refer to an emergency situation such as sudden braking or collision, the buffer mechanism 4 can drive the drive shaft 31 to rotate, so that the sliding rail 11 can slide, and when the sliding rail 11 slides, it can slide in the direction opposite to the acceleration of the vehicle, that is, when the vehicle is collided, if the acceleration is forward, the upper body of the occupant will move backward relative to the vehicle, and the sliding rail 11 slides in the direction opposite to the acceleration of the vehicle, that is, it moves a certain distance in the same direction as the occupant. The upper and lower body of the occupant move in the same direction, which reduces the possibility of spinal injury, and solves the technical problem in the related technology that when the occupant encounters a collision or sudden braking in a zero-gravity sitting position, the spine of the occupant and the seat will be relatively squeezed, which is easy to cause spinal compression and poses a major safety hazard.

[0034] In some optional embodiments, the electric seat slide rail further includes a conversion mechanism 5, the conversion mechanism 5 is connected to the slide rail 11, and the conversion mechanism 5 is connected to the drive shaft 31, the conversion mechanism 5 is configured to convert the rotation of the drive shaft 31 around the axis of the drive shaft 31 into the sliding of the slide rail 11 along the extension direction of the slide rail 11, that is, by connecting the slide rail 11 and the drive shaft 31 to the conversion mechanism 5 respectively, the rotation around the axial direction of the drive shaft 31 can be converted into the sliding around the extension direction of the slide rail 11. Specifically, a gear box can be installed between the fixed rail 12 and the slide rail 11, the gear box is provided with a turbine, and a screw rod is fixed on the fixed rail 12, the turbine can cooperate with the screw rod, when the drive shaft 31 rotates around its own axis under the drive of the drive motor 6, it also drives the turbine to rotate, so that the turbine slides along the screw rod, and then drives the slide rail 11 to move.

[0035] In some optional embodiments, the buffer mechanism 4 may include: a drive component, which is installed on the connecting bracket 2; a flywheel 42, which is fixed to the drive shaft 31, and in the second state, the drive component drives the flywheel 42 to rotate around the axis of the drive shaft 31, and the flywheel 42 and the drive shaft 31 can be connected by a spline. Since the flywheel 42 and the drive shaft 31 are fixed to each other, the drive component drives the flywheel 42 to rotate, which also causes the drive shaft 31 to rotate synchronously. In the absence of emergency situations such as collision, the rotation of the drive shaft 31 can be driven by the drive motor 6, and when a collision occurs, the drive motor 6 does not work. At this time, the flywheel 42 is driven to rotate by the drive component, so that the flywheel 42 drives the rotating shaft to rotate, and the sliding rail 11 can also move a certain distance synchronously with the occupant. By using the flywheel 42 to drive the rotating shaft to rotate, the structural layout of the electric seat slide rail can be reduced as much as possible. The drive assembly can be configured to include gears, which are connected to a moving part and a driving part. The control mechanism can be connected to the moving part and the driving part signals respectively. When there is no emergency such as collision, the control mechanism can control the moving part to drive the gear to a position away from the flywheel 42, and the driving part does not work. When an emergency occurs, the control mechanism controls the moving part to drive the gear to a position close to the flywheel 42, and the control mechanism controls the driving part to work, so that the driving part drives the gear to rotate, and the gear can also drive the flywheel 42 to rotate. It should be understood that the above structure is only one possible implementation method, and the drive assembly can also drive the flywheel 42 to rotate in other ways.

[0036] In some optional embodiments, the driving assembly may include: a guide cylinder segment 411 and a guide open segment 412 connected to the guide cylinder segment 411, the guide cylinder segment 411 is communicated with the guide open segment 412, the guide cylinder segment 411 and the guide open segment 412 are jointly arranged around the outer periphery of the flywheel 42 and are spaced apart from the flywheel 42, the guide cylinder segment 411 may not affect the rotation of the flywheel 42, the opening 4121 of the guide open segment 412 is arranged on a side close to the flywheel 42, and the end of the guide cylinder segment 411 away from the guide open segment 412 is connected to a driving device; a driving steel ball 43, in a first state, the driving steel ball 43 is accommodated in the guide cylinder segment 411, and in a second state, the The driving device drives the driving steel ball 43 to slide along the inner wall of the guide cylinder section 411, and makes the driving steel ball 43 drive the flywheel 42 to rotate around the axis of the driving shaft 31 in the guide open section 412. In the first state, the driving steel ball 43 is accommodated in the guide cylinder section 411. At this time, the guide cylinder section 411, the guide open section 412 and the driving steel ball 43 are all spaced apart from the flywheel 42. Since the flywheel 42 and the driving shaft 31 are fixed to each other, when the driving steel ball 43 is accommodated in the guide cylinder section 411, the driving steel ball 43 and other structures do not affect the movement of the flywheel 42. In the second state, when the driving steel ball 43 moves between the guide open section 412 and the flywheel, it can drive the flywheel 42 to rotate, thereby driving the driving shaft 31 to rotate. In the embodiment of the present application, the driving steel ball 43 is used to drive the driving shaft 31 to rotate, so that when the driving steel ball 43 is placed in the guide cylinder section 411, the seat can always remain effectively locked, and in complex working conditions such as collision, the seat can move synchronously with the moving direction of the occupant's upper body, thereby improving safety; preferably, the flywheel 42 can have gear teeth, and the sides of the gear teeth are all set to be arc-shaped. When the driving steel ball 43 slides to the guide open section 412, the driving steel ball 43 cooperates with the gear teeth of the flywheel 42. Since the sides of the gear teeth are arc-shaped, the circular driving steel ball 43 is easier to drive the flywheel 42 to rotate. In the embodiment of the present application, the buffer mechanism 4 having structures such as the guide cylinder section 411 and the guide open section 412 is integrated with the driving motor 6, and both are installed on the connecting bracket 2, with a compact structure and high integration and versatility.

[0037] In some optional embodiments, a through opening 4111 is provided on a side of the guide cylinder section away from the guide open section 412, a bead blocking layer is provided on the inner wall of the guide cylinder section 411, and the driving steel ball 43 is located between the through opening 4111 and the bead blocking layer; the driving device includes gunpowder filled in the through opening 4111 and a detonation mechanism connected to the through opening 4111, and the bead blocking layer can effectively prevent the driving steel ball 43 from always being located between the through opening 4111 and the bead blocking layer when the gunpowder at the through opening 4111 is not detonated by the detonation mechanism, and the bead blocking layer can be made of plastic material, and the driving steel ball 43 can quickly break through the bead blocking layer under high-speed movement, and the through opening 4111 is filled with gunpowder and connected with the detonation mechanism to prevent the driving steel ball 43 from slipping out of the through opening 4111, thereby maintaining the continuous effectiveness of the buffer mechanism 4 when not in use. The detonation mechanism ignites the gunpowder and then emits gas, which can drive the steel ball 43 to move as quickly as possible when a collision occurs, further improving the safety of the electric seat slide rail. The buffer mechanism 4 drives the steel ball 43 to drive the flywheel 42 to rotate to absorb the displacement of the slide rail 11. The specific displacement amount and action time can be calibrated according to the collision acceleration and energy of the whole vehicle. The energy absorption structure can be more accurately adapted and has high adjustment adaptability.

[0038] In some optional embodiments, a bead collecting bucket 44 is fixed to one end of the guide open section 412 away from the guide cylinder section 411, and the bead collecting bucket 44 is connected to the guide open section 412. The bead collecting bucket 44 can collect the driving steel balls 43 that have passed through the guide open section 412 to prevent the driving steel balls 43 from falling out. Preferably, the axis of the bead collecting bucket 44 can have a certain inclination angle compared to the axis of the driving shaft 31. When the electric seat slide is fixed on the vehicle body, the end of the bead collecting bucket 44 away from the guide open section 412 can be slightly lower than the end of the bead collecting bucket 44 close to the guide open section 412, further preventing the driving steel balls 43 received in the bead collecting bucket 44 from falling out of the bead collecting bucket 44.

[0039] In some optional embodiments, the driving assembly further includes a baffle 45, the baffle 45 is fixed to the connecting bracket 2, and the baffle 45 is installed on one side of the guide opening section 412, the baffle 45 can further prevent the driving steel ball 43 from escaping from the side of the guide opening section 412 when passing through the guide opening section 412, so that the driving steel ball 43 can smoothly fall into the bead collecting bucket 44. Preferably, the plate surface of the baffle 45 is arranged perpendicular to the axis of the driving shaft 31, and the baffle 45 protrudes toward the side close to the flywheel 42. In the embodiment of the present application, the baffle 45 can be arranged at both the guide cylinder section and the guide opening section 412, and a through hole can be opened in the middle position of the baffle 45, and the flywheel 42 passes through the through hole, the baffle 45 is fixed on the connecting bracket 2, and the guide cylinder section and the guide opening section 412 can be connected to the baffle 45, which can enhance the installation stability of the guide cylinder section and the guide opening section 412 on the connecting bracket 2.

[0040] Preferably, the drive shaft 31 connected to the drive motor 6 may have a certain rigidity. At the same time, in order to achieve the accuracy of seat adjustment and avoid the seat from getting stuck during the adjustment process, and to protect the drive motor from overload damage, a flexible shaft 32 may be fixed at the end of the drive shaft 31, and the two flexible shafts 32 located at both ends of the drive shaft 31 are respectively connected to the conversion mechanism 5 of the two slide rails 11. The drive shaft 31 is flexibly connected to the flexible shaft 32, and the drive motor 6 and the buffer mechanism 4 can be disassembled independently. The buffer mechanism 4 is easy to maintain after it is activated, and the core components of the electric seat slide rail will not be damaged. The system has a high degree of modularization and high maintenance convenience.

[0041] An embodiment of the present application also provides a seat slide system, which includes the above-mentioned electric seat slide. The seat slide system may also include: a controller, wherein the controller signal is connected to the detonation mechanism. In the embodiment of the present application, the signal connection is an electrical signal connection, and the controller may be an ECU controller. The ECU controller is connected to the detonation mechanism through a wiring harness, so that the detonation mechanism can detonate the gunpowder at the opening 4111.

[0042] In some optional embodiments, the seat rail system further includes a signal monitoring system, and the signal of the signal monitoring system is connected to the controller. In the embodiment of the present application, the signal monitoring system is set as an acceleration sensor. The acceleration sensor can not only monitor the acceleration value of the vehicle, but also monitor the direction of the acceleration. By using the acceleration sensor as the signal monitoring system, it is not necessary to add other signal monitoring systems. The existing acceleration sensor of the vehicle can be used, which can save the manufacturing cost of the vehicle. When the vehicle collides, the acceleration sensor in the vehicle can transmit the collision signal to the vehicle ECU controller. After the ECU controller performs logical operations, it sends a detonation command signal to the detonation mechanism. The detonation mechanism detonates the gunpowder, drives the multiple driving steel balls 43 inside the guide cylinder section 411 to move along the inner wall of the guide cylinder section 411. Under the continuous extrusion of the multiple driving steel balls 43, the flywheel 42 rotates, and then drives the drive shaft 31 to rotate. The drive shaft 31 drives the flexible shafts 32 at both ends to rotate together, so that the sliding rail 11 can slide along the fixed rail 12 with a small amplitude to absorb the impact acceleration during the collision.

[0043] Furthermore, two mounting positions 21 may be provided on the connecting bracket 2, each mounting position 21 is fixed with a buffer mechanism 4, the flywheels 42 in the two buffer mechanisms 4 may rotate in different directions, and the openings 4111 of the guide cylinder sections 411 of the two buffer mechanisms 4 may be connected to detonation mechanisms, and the controller may control the detonation mechanisms in the two buffer mechanisms 4 respectively. When the front end or rear end of the vehicle is hit, the acceleration sensor may detect accelerations in different directions, and after the acceleration sensor transmits the detected accelerations in different directions to the ECU controller, the ECU controller may control different detonation mechanisms to detonate according to the accelerations in different directions, so that the corresponding flywheel 42 drives the sliding rail 11 to slide in the corresponding direction.

[0044] An embodiment of the present application also provides a vehicle, which includes the above-mentioned electric seat slide rail. The structures in the electric seat slide rail of the vehicle are the same as the structures in the above-mentioned electric seat slide rail, and will not be repeated here.
