Description

Technical Field

[0001] This utility model relates to the field of seat technology, specifically a high-strength seat connection mechanism. Background Technology

[0002] A seat is a piece of seating with a backrest, and some also have armrests. Existing seats are also divided into airport seats, car seats, bus seats, family seats, restaurant seats, child safety seats, and leisure seats, etc., according to their different usage scenarios.

[0003] Existing car seats are not directly installed into the car. Typically, a seat mounting base is first installed at the seat's mounting location, and then the seat is installed onto this base. Through a sliding rail mechanism on the seat mounting base, the seat can move forward and backward within the vehicle to accommodate the legroom needs of different drivers or passengers. For example, a driver can adjust the seat's fore-and-aft position according to their height and driving habits to ensure comfortable pedal operation and steering wheel control. This type of seat mounting base used for connecting and installing the seat can be referred to as a seat connection mechanism.

[0004] However, the slide rails on existing seat connection mechanisms are generally assembled from stamped parts, resulting in low overall structural strength. If these slide rails are subjected to the load applied to them during long-term vehicle operation, they may deform, causing them to malfunction. Therefore, this does not meet the current requirements, and we have proposed a high-strength seat connection mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength seat connection mechanism to solve the problems mentioned in the background art, where the slide rails on the existing seat connection mechanisms are generally assembled from stamped parts, resulting in low overall structural strength. When the slide rail is subjected to the load force applied to it by the vehicle during long-term driving, it may deform, leading to the slide rail being unable to function properly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength seat connection mechanism, comprising a metal base, on both sides of the upper surface of the metal base a vehicle seat slide rail is fixedly installed, a vehicle seat slider is slidably installed inside the vehicle seat slide rail, a metal plate is fixedly installed on the upper surface of the two vehicle seat sliders, the lower surface of which is slidably connected to the metal base, a fixed motor is fixedly installed on the lower side inside the metal plate, the output shaft of the fixed motor is connected to a transmission shaft through a coupling, a shaft is provided at both the front and rear of the transmission shaft, a second sprocket is fixedly sleeved on the outer surface of the shaft, a first sprocket is fixedly sleeved on one side of the second sprocket on the outer surface of the transmission shaft, and the two second sprockets and the two first sprockets are connected in series by a chain respectively;

[0007] A threaded rod is fixed to the lower end face of the rotating shaft. A second high-hardness tooth row is provided on the outer side of the threaded rod through a threaded structure. A guide rod that moves vertically through the second high-hardness tooth row is provided at both the front and rear of the threaded rod.

[0008] Below the second high-hardness toothed row is a first high-hardness toothed row fixed to the outer surface of the metal base.

[0009] Preferably, the top ends of the teeth on the outer surfaces of the second high-hardness tooth row and the first high-hardness tooth row are both arc-shaped, and the width of the teeth on the second high-hardness tooth row is consistent with the gap between the teeth on the first high-hardness tooth row.

[0010] Preferably, the upper surface of the metal plate is provided with multiple seat mounting holes on both sides, and the metal plate is fixed to the vehicle seat slider by screws.

[0011] Preferably, one side of the vehicle seat slide rail is provided with a strip groove located on the outer surface of the metal base, and both sides of the lower inner wall of the strip groove are provided with a through hole for bolt fixing.

[0012] Preferably, the top end of the rotating shaft is located inside the metal plate housing, and the rotating shaft located inside the metal plate is connected to the metal plate by a roller bearing.

[0013] Preferably, a remote control module is fixedly installed on one side of the outer surface of the fixed motor, and the fixed motor and the remote control module are electrically connected.

[0014] Preferably, a square cover plate is provided above the fixed motor on the upper surface of the metal plate, and the metal plate and the square cover plate are fixed together by screws.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model adds a metal plate that is slidably connected to a metal base between the vehicle seat slider and the seat, which is originally used to directly fix the seat. After the seat, which is fixed to the metal plate, is adjusted to a suitable position by the vehicle seat slide rail and the vehicle seat slider, the two second high-hardness toothed rows are fixed downward by the fixing motor. When the two second high-hardness toothed rows respectively mesh with the two first high-hardness toothed rows fixed to the upper end face of the metal base, the metal plate can be fixed in the current position. Then, the front-rear load generated during the vehicle's operation will be transmitted to the first high-hardness toothed rows, the second high-hardness toothed rows, and the vehicle seat slider through the metal plate. The left-right load generated during the vehicle's operation will be transmitted to the sliding connection structure between the lower end face of the metal plate and the metal base and the vehicle seat slide rail through the metal plate. Through the above technical solution, the load borne by the vehicle seat slide rail and the vehicle seat slider during the vehicle's operation can be distributed, thereby improving their overall strength and increasing their service life.

[0017] 2. This utility model uses a fixed motor to automatically and synchronously drive two second high-hardness tooth rows to move up and down, thereby fixing the metal plate. The above technical solution eliminates the need for manual operation in the metal plate fixing process, thus improving the automation level of the equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The vehicle seat slide rail 2 (model JF-G-01), fixed motor 7 (model DM542), and threaded rod 13 (model M10) mentioned in this utility model can be obtained from the market or through private customization.

[0025] Please see Figures 1 to 4 An embodiment of this utility model provides a high-strength seat connection mechanism, including a metal base 1. A vehicle seat slide rail 2 is fixedly installed on both sides of the upper surface of the metal base 1. A vehicle seat slider 3 is slidably installed inside the vehicle seat slide rail 2. A metal plate 4 is fixedly installed on the upper surface of the two vehicle seat sliders 3, and its lower surface is slidably connected to the metal base 1. A fixed motor 7 is fixedly installed on the lower side inside the metal plate 4. The output shaft of the fixed motor 7 is connected to a transmission shaft 8 through a coupling. A shaft 12 is provided at the front and rear of the transmission shaft 8. A second sprocket 10 is fixedly sleeved on the outer surface of the shaft 12. A first sprocket 9 is fixedly sleeved on one side of the second sprocket 10 on the outer surface of the transmission shaft 8. The two second sprockets 10 and the two first sprockets 9 are connected in series by a chain 11.

[0026] A threaded rod 13 is fixed to the lower end face of the rotating shaft 12. A second high-hardness tooth row 14 is provided on the outer side of the threaded rod 13 and connected to it through a threaded structure. A guide rod 15 is provided at both the front and rear of the threaded rod 13 and moves vertically through the second high-hardness tooth row 14.

[0027] Below the second high-hardness toothed row 14 is a first high-hardness toothed row 5 fixed to the outer surface of the metal base 1.

[0028] The vehicle seat slide rail 2 has a strip-shaped groove on one side of the outer surface of the metal base 1, and a bolt fixing through hole is provided on both sides of the inner wall of the lower end of the strip-shaped groove; a remote control module is fixedly installed on one side of the outer surface of the fixed motor 7, and the fixed motor 7 and the remote control module are electrically connected; multiple seat mounting holes 16 are provided on both sides of the upper surface of the metal plate 4, and the metal plate 4 and the vehicle seat slider 3 are fixed by screws; when the equipment is needed, the metal base 1 is fixed to the corresponding position on the vehicle through the bolt fixing through holes on the inner wall of the strip-shaped groove. After the metal base 1 is fixed, the metal plate... 4. The seat mounting holes 16 on the upper end face fix the seat to the upper end face of the metal plate 4. After the seat is fixed, the position of the seat is adjusted by the vehicle seat slide rail 2 and the vehicle seat slider 3 that are indirectly connected to it. After the position of the seat is adjusted, the fixed motor 7 fixedly installed inside the metal plate 4 is remotely started by the remote control module. The fixed motor 7 can drive the transmission shaft 8 connected to it and the two shafts 12 connected to the transmission shaft 8 by a first sprocket 9, a second sprocket 10 and a chain 11 respectively to rotate. When the shaft 12 rotates, the threaded rod 13 fixed to it will rotate together.

[0029] Since the outer surfaces of the second high-hardness tooth row 14, which is connected to the threaded rod 13 by a threaded structure, are vertically traversed by two guide rods 15 on both sides, the second high-hardness tooth row 14 cannot rotate on its own.

[0030] When the threaded rod 13 rotates, the second high-hardness toothed row 14, which is threadedly connected to it but cannot rotate on its own, will move up and down under the drive of the threaded structure. At this time, the second high-hardness toothed row 14 moves downward. As the second high-hardness toothed row 14 descends, it will mesh with the first high-hardness toothed row 5 fixed to the upper end face of the metal base 1. When the two mesh with each other, the metal plate 4 can be fixed in the current position. When the metal plate 4 is fixed, the front-rear load generated during the vehicle's movement will be transmitted through the metal plate 4 to the first high-hardness toothed row 5, the second high-hardness toothed row 14, and the vehicle seat slider 3. The left-right load generated during the vehicle's movement will be transmitted through the metal plate 4 to the sliding connection structure between the lower end face of the metal plate 4 and the metal base 1 and the vehicle seat slide rail 2. Through the above technical solution, the load borne by the vehicle seat slide rail 2 and the vehicle seat slider 3 during the vehicle's movement can be shared, thereby improving their overall strength and increasing their service life.

[0031] The top ends of the teeth on the outer surfaces of the second high-hardness tooth row 14 and the first high-hardness tooth row 5 are both arc-shaped heads 6, and the width of the teeth on the second high-hardness tooth row 14 is consistent with the gap between the teeth on the first high-hardness tooth row 5. With the teeth having arc-shaped heads 6, even if the teeth on the second high-hardness tooth row 14 and the first high-hardness tooth row 5 collide directly, they will be offset by the push of the arc-shaped surface. The above technical solution can prevent the second high-hardness tooth row 14 from failing to mesh with the first high-hardness tooth row 5. Furthermore, the thickness of the teeth on the second high-hardness tooth row 14 can prevent gaps from forming between the second high-hardness tooth row 14 and the first high-hardness tooth row 5, thus preventing the second high-hardness tooth row 14 from shaking due to the inertia during vehicle operation.

[0032] The top end of the rotating shaft 12 is located inside the outer shell of the metal plate 4, and the rotating shaft 12 located inside the metal plate 4 is connected to the metal plate 4 by a roller bearing; the roller bearing structure between the rotating shaft 12 and the metal plate 4 can ensure the stability of the rotating shaft 12 and prevent it from tilting.

[0033] A square cover plate is provided above the fixed motor 7 on the upper surface of the metal plate 4, and the metal plate 4 and the square cover plate are fixed together by screws; the square cover plate can protect the fixed motor 7.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
