[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] The following description, in conjunction with the accompanying drawings, further illustrates this application:

[0028] like Figures 1 to 6 As shown, this application provides a mounting bracket assembly for an automotive seat slide rail motor, including two slide rail motors 1 and two sets of seat slide rails 2. The slide rail motors 1 and seat slide rails 2 are configured to cooperate with each other. One slide rail motor 1 is suitable for driving a corresponding set of seat slide rails 2. Specifically, the seat slide rail 2 includes a first slide rail 21 and a second slide rail 22. The first slide rail 21 and the second slide rail 22 are respectively connected to the vehicle body and a seat is installed thereon. A transmission device 23 (including an HDM gearbox, drive shaft and other transmission components) is provided between the first slide rail 21 and the second slide rail 22. The slide rail motor 1 is connected to the transmission device 23. The slide rail motor 1 is suitable for driving the transmission device 23 to make the first slide rail 21 and the second slide rail 22 slide relative to each other, thereby driving the seat to move.

[0029] It is understandable that when there are two slide rail motors 1 and two seat slide rails 2, the space under the seat can be used without taking up space, and the seat can be stably supported for sliding adjustment. When there are more than two slide rail motors 1 and two seat slide rails 2, the slide rail motor 1 synchronous motion system and method of this application can also be used for arrangement and control.

[0030] The slide rail motor 1 has a control chamber 11 near the drive side. The drive shaft 14 of the slide rail motor 1 passes through the control chamber 11. The slide rail motor 1 has a built-in control module 12. The control module 12 is adapted to be housed in the control chamber 11 and is coaxially and spaced around the drive shaft 14. The control module 12 is installed inside the slide rail motor 1 by avoiding the drive shaft 14, which ensures stability and reduces the overall compactness of the slide rail motor 1, thereby freeing up space under the seat. The synchronous control requirement of the slide rail motor 1 caused by the built-in control module 12 can be achieved by the synchronous movement method of the slide rail motor 1 in the above embodiment.

[0031] In the traditional method of two slide rail motors 1 sharing a single controller, the power supply voltage and drive motor current are prone to mutual interference. However, this application uses a built-in control module 12 design to bring the controller closer to the motor, shorten the signal transmission distance, reduce the risk of electromagnetic interference, and simplify the wiring design. This makes the collected motor data more accurate and reliable, thereby improving the control accuracy and reliability of the controller.

[0032] In some embodiments, the control module 12 and the drive part of the slide rail motor 1 are directly connected by pins. The connection between the motor and the circuit board can be realized by using the pins of some components themselves, which simplifies the wiring, makes the installation process more convenient, and reduces the installation difficulty and cost.

[0033] like Figures 1 to 6 In the illustrated embodiment, a bracket assembly 3 is provided between the slide rail motor 1 and the seat slide rail 2. A connecting seat 31 is provided on the bracket assembly 3. A through hole 32 is provided on the connecting seat 31. A vibration damping pad 33 is provided inside the connecting seat 31. A first rotary locking structure 311 is provided on the periphery of the connecting seat 31. A second rotary locking structure 13 is provided on the periphery of the drive side of the slide rail motor 1. The drive shaft 14 is adapted to pass through the through hole 32 and to make the drive side of the slide rail motor 1 fit tightly against the vibration damping pad 33. The slide rail motor 1 is adapted to rotate circumferentially, so that the first rotary locking structure 311 and the second rotary locking structure 13 cooperate and lock.

[0034] In some embodiments, the vibration isolation pad 33 is made of a flexible or elastic material, such as rubber. When the first rotary locking structure 311 and the second rotary locking structure 13 are engaged and locked, the drive side of the slide rail motor 1 and the vibration isolation pad 33 can maintain an interference fit. The micro-deformation and flexibility of the vibration isolation pad are used to buffer the connection between the slide rail motor 1 and the connecting seat 31, thereby reducing the noise generated by vibration.

[0035] The circumferential rotation locking method of the first rotary locking structure 311 and the second rotary locking structure 13 can lock the slide rail motor 1 and the connecting seat 31 while keeping the square head of the drive shaft 14 aligned with the square hole of the HDM gearbox. This can effectively reduce the assembly difficulty and solve the problem of angular alignment between the square head of the drive shaft 14 and the square hole of the HDM gear shaft during the assembly of the slide rail motor 1 and the connecting seat 31.

[0036] like Figures 1 to 4 In the illustrated embodiment, the first rotary snap-fit ​​structure 311 includes a slot portion 3111 and a barb portion 3112, and the second rotary snap-fit ​​structure 13 includes a boss portion 131 and a groove portion 132. The slot portion 3111 and the boss portion 131 are adapted to engage and restrict the slide rail motor 1 from disengaging from the connecting seat 31. The barb portion 3112 and the groove portion 132 are adapted to engage and restrict the slide rail motor 1 from disengaging from the connecting seat 31. The boss portion 131 is adapted to move within the slot portion 3111 so that the barb portion 3112 engages with the groove portion 132.

[0037] like Figure 4 In the illustrated embodiment, the slot portion 3111 is opened circumferentially along the connecting shaft and the openings all face clockwise (counterclockwise). The slide rail motor 1 can rotate counterclockwise (clockwise) so that the boss portion 131 enters from the opening of the slot portion 3111 and moves deeper along the slot portion 3111, so that the connecting seat 31 and the slide rail motor 1 are axially engaged and limited. During this process, the barb portion 3112 can conform to the outer surface of the slide rail motor 1 by its own deformation. As the slide rail motor 1 rotates relative to the connecting seat 31, the barb portion 3112 can slide into the groove portion 132, so that the connecting seat 31 and the slide rail motor 1 are engaged and limited axially and circumferentially, thereby locking the connecting seat 31 and the slide rail motor 1.

[0038] In some embodiments, the number of slot portions 3111 and boss portions 131 are the same and there are multiple slot portions 3111. The slot portions 3111 are arranged at intervals along the circumference of the connecting seat 31, and the boss portions 131 are arranged at intervals along the circumference of the slide rail motor 1. The slot portions 3111 and boss portions 131 are suitable for one-to-one corresponding engagement and connection, which can improve the stability of the initial engagement between the connecting seat 31 and the slide rail motor 1, reduce the reaction force at the vibration isolation pad 33 along the axial direction of the slide rail motor 1, and reduce the difficulty of locking the hook portion 3112 and the groove portion 132.

[0039] like Figure 5 In the illustrated embodiment, the first rotary snap-fit ​​structure 311 includes a guide groove 3113 and a fixing groove 3114, and the second rotary snap-fit ​​structure 13 includes a boss portion 131. The guide groove 3113 and the fixing groove 3114 are distributed circumferentially along the connecting seat 31. A movable snap-fit ​​portion 3115 is provided on the side of the guide groove 3113 near the fixing groove 3114. The boss portion 131 is adapted to enter the guide groove 3113 along the axial direction of the connecting seat 31. When the boss portion 131 is adapted to move along the axial direction of the connecting seat 31, the movable snap-fit ​​portion 3115 is adapted to elastically deform along the radial direction of the connecting seat 31, so that the boss portion 131 is adapted to enter the fixing groove 3114 from the guide groove 3113. The movable snap-fit ​​portion 3115 and the boss portion 131 are adapted to cooperate to restrict and fix the boss portion 131.

[0040] Understandably, the movable locking part 3115 plays a one-way locking role. When the boss part 131 moves from the guide groove 3113 to the fixed groove 3114, the movable locking part 3115 is difficult to restrict the movement of the boss part 131 under the guidance of the contact surface direction with the boss part 131. However, when the boss part 131 enters the fixed groove 3114, the contact surface direction between the boss part 131 and the movable locking part 3115 changes. The boss part 131 is difficult to elastically deform along the radial direction of the connecting seat 31 when the movable locking part 3115 is pressed. Therefore, the boss part 131 is successfully restricted in the fixed groove 3114 and is difficult to detach.

[0041] like Figure 5 In the embodiment shown, the guide groove 3113 has an inlet on the side near the mounting of the slide rail motor 1. When the slide rail motor 1 mates with the connecting seat 31 along the axial direction, the boss portion 131 can enter the guide groove 3113 from this side. The fixing groove 3114 has an inlet on the side near the guide groove 3113. The boss portion 131 is adapted to push open the movable latching portion 3115 and enter the fixing groove 3114. The fixing groove 3114 restricts the movement of the boss portion 131 on the opposite side of the mating direction (axial direction) between the slide rail motor 1 and the connecting seat 31 and the inlet. The movable latching portion 3115 restricts the movement of the boss portion 131 on the inlet side of the fixing groove 3114.

[0042] like Figure 5In the illustrated embodiment, the guide groove 3113 narrows in width from the side away from the fixed groove 3114 to the side closer to the fixed groove 3114 and connects with the movable latching part 3115. One end of the boss part 131 narrows in width from the other end. When the boss part 131 moves circumferentially along the connecting seat 31 within the guide groove 3113, as the guide groove 3113 narrows, the boss part 131 is adapted to engage with the movable latching part 3115 in the radial direction of the connecting seat 31 and the slide rail motor 1, and is adapted to more smoothly compress the movable latching part 3115 to deform in the radial direction of the connecting seat 31 and the slide rail motor 1, which can effectively reduce the difficulty of the boss part 131 passing through the movable latching part 3115.

[0043] like Figure 5 In the embodiment shown, the guide groove 3113, the fixing groove 3114, and the boss 131 are all knife-shaped structures. One side of the knife-shaped structure is suitable for guiding, so that the boss 131 can enter the fixing groove 3114 from the guide groove 3113. The other side of the knife-shaped structure is used for positioning, restricting the boss 131 from returning to the guide groove 3113 from the fixing groove 3114.

[0044] like Figure 5 In the embodiment shown, the number of guide grooves 3113, fixing grooves 3114 and bosses 131 are the same and there are multiple of each. The structural combination formed by the spaced arrangement of one guide groove 3113 and one fixing groove 3114 is arranged circumferentially along the connecting seat 31. The bosses 131 are arranged circumferentially along the slide rail motor 1. The guide grooves 3113, fixing grooves 3114 and bosses 131 are adapted to be connected in a one-to-one correspondence.

[0045] like Figures 1 to 3 In the embodiment shown in Figure 6, the slide rail motor 1 is adapted to be fixed on the first slide rail 21 by the bracket assembly 3 and connected with the transmission device 23. The bracket assembly 3 is provided with a gripper connection structure 34. The front end of the gripper connection structure 34 is adapted to be fastened to the sides of the first slide rail 21 away from the second slide rail 22 and the sides adjacent to it, so that the slide rail motor 1 is arranged close to the second slide rail 22.

[0046] The contour-following connection between the gripper connection structure 34 and the first guide rail can improve the connection stability between the bracket assembly 3 and the first slide rail 21, increase the contact area between the gripper connection structure 34 and the first guide rail, make it easier to distribute the force, and reduce the shaking and abnormal noise between the bracket assembly 3 and the first slide rail 21.

[0047] The slide rail motor 1 is adapted to have at least partial overlap with the projection of the first slide rail 21 and the second slide rail 22 in the vertical plane through the gripper connection structure 34 of the bracket assembly 3. This allows for full utilization of the space on both sides of the seat slide rail 2, reduces the space occupied under the seat, and facilitates seat design.

[0048] In some embodiments, a first positioning part 211 is provided along the length direction on the side of the first slide rail 21 away from the second slide rail 22, and a second positioning part 341 is provided on the gripper connecting structure 34. The first positioning part 211 and the second positioning part 341 are adapted to be fitted together. The first positioning part 211 and the second positioning part 341 can assist the gripper connecting structure 34 in engaging and positioning with the first slide rail 21, so as to facilitate the alignment and engagement of the square head of the drive shaft 14 with the square hole of the HDM gearbox between the first slide rail 21 and the second slide rail 22.

[0049] In some embodiments, the first positioning part 211 and the second positioning part 341 are of multiple types and the same number. By using multiple types of first positioning parts 211 and second positioning parts 341, the pre-positioning between the first slide rail 21 and the gripper connection structure 34 is achieved, making the positioning more accurate.

[0050] like Figure 6 In the embodiment shown, the first positioning part 211 includes one or more first positioning blocks and a first positioning port 121, and the second positioning part 341 includes one or more second positioning ports 121 and a second positioning block. The first positioning block and the second positioning port 121 cooperate for positioning, and the first positioning port 121 and the second positioning block cooperate for positioning, so as to improve the accuracy of the connection between the first slide rail 21 and the gripper connection structure 34.

[0051] like Figure 6 In the embodiment shown, the front end of the gripper connection structure 34 is provided with a locking port 342, and the first slide rail 21 is provided with a detachable locking device 212. The locking port 342 and the locking device 212 are adapted to cooperate with each other to lock. The locking device 212 can ensure that the gripper connection structure 34 is fixed on the first slide rail 21, reducing the probability of the bracket assembly 3 shaking and making abnormal noise on the first slide rail 21.

[0052] In some embodiments, the locking device 212 may be a bolt-type locking device 212.

[0053] like Figure 3 and 6 In the embodiment shown, the gripper connection structure 34 has a drive channel 343 along the connection direction between the transmission device 23 and the slide rail motor 1. The drive shaft 14 is adapted to be housed in the drive channel 343. The gripper connection structure 34 can provide circumferential protection for the drive shaft 14, reducing the probability of the drive shaft 14 coming into contact with foreign objects.

[0054] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are only the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope of this application. All such changes and modifications fall within the scope of this application as claimed. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
