Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a rotating automobile seat. Background Art

[0002] A car swivel seat is a seat design that enables the seat to rotate. This design allows passengers to easily turn around, face or move away from a certain direction in the car, making it convenient to communicate or enjoy the entertainment facilities in the car. The design concept of a car swivel seat is mainly based on humanization, comfort and convenience. It can improve the comfort of passengers and allow passengers to move and change postures more freely in the car.

[0003] The rotating seats of cars are generally equipped with an unlocking mechanism. When the seat angle and orientation need to be changed, the unlocking action is completed by manual operation. During the car safety collision test, the impact from the front of the vehicle is the greatest. The unlocking mechanism of the rotating seat is prone to failure during the vehicle safety test and cannot meet the safety test requirements. Taking a rotating seat unlocking mechanism in the related technology as an example, the unlocking mechanism is set on the rear side of the seat near the rear of the car. In the locked state, the lock tongue of the unlocking mechanism is engaged with the card slot on the side of the seat base. When the vehicle is hit from the front, the lock tongue is easy to slip out in the direction away from the card slot and unlock under the action of external force, resulting in failure to meet the car safety test requirements. Utility Model Content

[0004] In view of this, the utility model provides a rotating seat for an automobile, so as to solve the problem that the unlocking mechanism of the rotating seat is easily unlocked when impacted and cannot meet the requirements of automobile safety tests.

[0005] The utility model provides a rotating seat for a car, comprising:

[0006] The rotating disk is provided with a locking groove;

Since the L-shaped rod has higher stability and load-bearing capacity, it can withstand more rotation cycles, thereby extending the service life. And because the L-shaped rod has a larger moment of inertia, it can carry a larger load. In addition, the operating handle is set to L-shaped, with a simple structure, convenient on-site repair and adjustment, and easier installation and maintenance.

[0013] In an optional embodiment, a connecting shaft is provided on the operating handle, and the operating handle is suitable for rotating along the connecting shaft.

[0014] Beneficial effect: the second end of the operating handle rotates along the connecting shaft under the drive of the transmission assembly, so that the first end of the operating handle is away from the locking position and the lock tongue is out of the limit position. This arrangement is convenient for operation and saves effort.

[0015] In an optional embodiment, the transmission assembly includes a pulling wire, one end of the pulling wire is connected to the output end of the driving assembly, and the other end of the pulling wire is connected to the second end of the operating handle.

The force direction is perpendicular to the second end of the operating handle, and there is no additional force loss. The design is reasonable.

[0019] In an optional embodiment, a sheath is provided on the pulling wire near the operating handle.

[0020] Beneficial effect: The sheath protects the pulling wire and prevents the pulling wire from being worn due to friction between the pulling wire and the bracket, thereby affecting the reliability of the unlocking mechanism.

[0021] In an optional embodiment, the unlocking mechanism further includes an elastic return mechanism, and the elastic return mechanism is transmission-connected to the operating handle.

[0022] Beneficial effect: The elastic return mechanism can realize the automatic return of the operating handle after unlocking, so that the lock tongue at the first end of the operating handle is re-locked under the action of the elastic return mechanism's rebound force, without the need to drive the operating handle by external force, which is convenient and time-saving.

[0023] In an optional embodiment, the rotating disk comprises:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0059] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0060] According to an embodiment of the utility model, a rotating seat for a car is provided, comprising:

[0061] The rotating disk 1 is provided with a locking groove 2;

[0062] The unlocking mechanism 3 includes a lock assembly 31 that is connected to the locking groove 2. The locking groove 2 and the unlocking mechanism 3 are both arranged on a side of the rotating seat close to the front of the vehicle, and the opening direction of the locking groove 2 faces the front of the vehicle.

[0063] In the vehicle safety test, the impact from the front of the vehicle is the largest, followed by the side impact, and the impact from the rear is the smallest, that is, the front of the vehicle is subject to the largest impact force, and the rear of the vehicle is subject to the smallest impact force. The unlocking mechanism 3 and the locking groove 2 are arranged on the front side of the rotating seat close to the front of the vehicle, and the opening of the locking groove 2 faces the front of the vehicle. Since the direction of the impact force on the front side with the largest impact is opposite to the unlocking direction, the locking reliability and safety of the rotating seat are higher, and it is not easy to be unlocked when it is hit during the vehicle safety test, which can meet the requirements of automobile safety testing.

[0064] In some embodiments, the unlocking mechanism 3 also includes an electric drive component and a transmission component 33; the lock component 31 includes an operating handle 311 and a locking tongue 312 arranged at the first end 3111 of the operating handle 311, and the second end 3112 of the operating handle 311 is transmission-connected to the electric drive component through the transmission component 33.

[0065] The second end 3112 of the lock assembly 31 is connected to the electric drive assembly through the transmission assembly 33. When the rotating seat needs to be unlocked, the electric drive assembly controls the lock assembly 31 through the transmission assembly 33 to realize electric unlocking, which improves the convenience of operation compared with the manual unlocking method in the related art. In addition, the electric drive assembly drives the operating handle 311 to move, and the lock tongue 312 quickly leaves the locked position, and the reaction speed is fast.

[0066] In some embodiments, Figure 1 As shown, the operating handle 311 is L-shaped, the long side of the L-shaped operating handle 311 corresponding to the second end 3112 is connected to the transmission assembly 33, and the short side of the L-shaped operating handle 311 corresponding to the first end 3111 vertically extends to form a locking tongue 312.

[0067] The operating handle 311 is set to be L-shaped, which has higher stability because it has a larger moment of inertia during rotation, can better resist external interference, and provide more stable rotation. Because it has better balance and stability, the L-shaped rod can provide higher rotation accuracy. Since the L-shaped rod has higher stability and load-bearing capacity, it can withstand more rotation cycles, thereby extending the service life. And because the L-shaped rod has a larger moment of inertia, it can carry a larger load. In addition, the operating handle 311 is set to be L-shaped, with a simple structure, convenient on-site repair and adjustment, and easier to install and maintain.

[0068] In some embodiments, a connecting shaft 36 is disposed on the operating handle 311 , and the operating handle 311 is suitable for rotating along the connecting shaft 4 .

[0069] The second end 3112 of the operating handle 311 rotates along the connecting shaft 36 under the drive of the transmission assembly 33, so that the first end 3111 of the operating handle 311 is away from the locking position, and the locking tongue 312 is out of the limit position. This arrangement is convenient for operation and saves effort.

[0070] Moreover, the long side of the L-shaped operating handle 311 is used as the transmission side, which makes it convenient to set a connecting shaft 36 on the long side to convert the linear motion of the transmission component 33 into the rotational motion of the operating handle 311, and to control the lock tongue 312 on the short side of the L-shaped operating handle 311 to make a quick response and action to achieve unlocking or locking.

[0071] In some embodiments, the transmission assembly 33 includes a pulling wire 331 , one end of the pulling wire 331 is connected to the output end of the driving assembly, and the other end of the pulling wire 331 is connected to the second end 3112 of the operating handle 311 .

[0072] The pulling wire 331 acts on the operating handle 311 and can act on the force application point quickly and accurately with high efficiency.

[0073] In some embodiments, the unlocking mechanism 3 further includes a bracket 34 , and the pulling wire 331 is mounted on the bracket 34 near the operating handle 311 .

[0074] The pulling wire 331 is mounted on the bracket 34 near the operating handle 311 to facilitate control of the force direction of the pulling wire 331 . The force direction is perpendicular to the second end 3112 of the operating handle 311 , and there is no additional force loss. The design is reasonable.

[0075] It should be noted that the bracket 34 of the unlocking mechanism 3 is arranged on the side of the upper plate 12 close to the front of the vehicle, the lock assembly 31 is arranged at an interval on the side of the bracket 34 close to the front of the vehicle, and the operating handle 311 of the lock assembly 31 is pivoted to the upper plate 12 through the connecting shaft 36; one end of the pulling wire 331 of the transmission assembly 33 passes through the slot on the bracket 34 and is connected to the second end 3112 of the operating handle 311, and the other end of the pulling wire 331 is connected to the power output end of the electric drive assembly. The electric drive assembly can be a motor, and the motor is connected to the control unit signal of the vehicle, and the start and stop of the motor can be controlled by the control unit.

[0076] In some embodiments, a sheath 3311 is provided on the pull wire 331 near the operating handle 311 .

[0077] The sheath 3311 protects the pulling wire 331 , and prevents the pulling wire 331 from being worn due to friction with the bracket 34 , thereby preventing the reliability of the unlocking mechanism 3 from being affected.

[0078] In some embodiments, the unlocking mechanism 3 further includes an elastic return mechanism 35 , and the elastic return mechanism 35 is transmission-connected to the operating handle 311 .

[0079] The elastic return mechanism 35 can realize the automatic return of the operating handle 311 after unlocking, so that the locking tongue 312 of the first end 3111 of the operating handle 311 is re-locked under the action of the elastic return mechanism 35, and there is no need to drive the operating handle 311 by external force, which is convenient and time-saving.

[0080] It should be noted that the elastic return mechanism 35 is disposed on a side of the upper plate 12 close to the front of the vehicle and is transmission-connected to the operating handle 311 .

[0081] Specifically, the elastic return mechanism 35 includes a return torsion spring sleeved on the connecting shaft 36. When the lock tongue 312 is in the locked state, the return torsion spring is in a natural state. When the pulling wire 331 pulls the second end 3112 of the operating handle 311, the operating handle 311 rotates to make the lock tongue 312 at the first end 3111 of the operating handle 311 disengage from the locking groove 2 and move away from the locked position. At this time, the return torsion spring is tightened with the rotation of the connecting shaft 36 to accumulate elastic potential energy. When the rotating seat rotates to a suitable position, the electric drive assembly is powered off, the pulling wire 331 no longer applies force to the operating handle 311, and the operating handle 311 rotates in the opposite direction and resets under the rebound action of the return torsion spring, so that the lock tongue 312 returns to the locked state.

[0082] According to an embodiment of the present utility model, on the other hand, a rotating disk 1 is provided, comprising:

[0083] The lower plate 11 is provided with a locking groove 2;

[0084] The upper plate 12 is rotatably disposed on the lower plate 11, and the upper plate 12 is provided with a through slot 121 for the locking tongue 312 to pass through;

[0085] The unlocking mechanism 3 , the locking tongue 312 of the operating handle 311 has a locked state in which the upper plate 12 is engaged with the locking groove 2 to lock the lower plate 11 , and an unlocked state in which the upper plate 12 is separated from the locking groove 2 to allow the upper plate 12 to rotate relative to the lower plate 11 .

[0086] A locking groove 2 is provided on the lower plate 11, which cooperates with the unlocking mechanism 3 provided on the upper plate 12 to facilitate locking or unlocking between the upper plate 12 and the lower plate 11. The locking tongue 312 on the operating handle 311 passes through the through groove 121 opened on the upper plate 12 and extends between the upper plate 12 and the lower plate 11, and is locked or disengaged with the locking groove 2 on the lower plate 11 to achieve locking and unlocking between the upper plate 12 and the lower plate 11.

[0087] In some embodiments, Figure 6 As shown, the end surface of the lower plate 11 facing the upper plate 12 near the through groove 121 protrudes upward to form a locking groove 2.

[0088] A locking groove 2 is provided on the end surface of the lower plate 11 near the through groove 121, so as to facilitate locking at the end point of the stroke of the operating handle 311, and the structure is compact; the lower plate 11 protrudes upward to form the locking groove 2, so as to facilitate the locking tongue 312 to engage therewith.

[0089] like Figures 2 to 6 As shown, the embodiment of the utility model provides a rotating plate 1 for a rotating seat of a car, and the rotating plate 1 includes Figure 5 The upper plate 12 shown and Figure 6 The lower plate 11 shown in the figure has a locking groove 2 disposed thereon, and an unlocking mechanism 3 installed on the upper plate 12. Figure 1 As shown, the unlocking mechanism 3 includes an L-shaped operating handle 311 and a pulling wire 331, one end of the pulling wire 331 is connected to a motor, and the other end of the pulling wire 331 is fixed to the second end 3112 of the L-shaped operating handle 311, that is, the end of the long side; the first end 3111 of the L-shaped operating handle 311, that is, the short side, vertically extends to form a columnar locking tongue 312, and the upper plate 12 is provided with a through slot 121 for the locking tongue 312 to pass through. A connecting shaft 36 is fixedly provided in the middle of the long side of the L-shaped operating handle 311, and a torsion spring is provided on the connecting shaft 36. When the upper plate 12 and the lower plate 11 are in the locked state, the lock tongue 312 is clamped in the locking groove 2 under the pre-tightening action of the torsion spring; when the swivel seat needs to be unlocked, the motor is started, the motor drives the pulling wire 331, the pulling wire 331 pulls the operating handle 311 to rotate along the connecting shaft 36, and the lock tongue 312 moves with the operating handle 311 in a direction away from the locking groove 6, disengages from the locking groove 2, and completes the unlocking of the swivel seat. Figure 2 After the adjustment of the rotating seat is completed, the motor is powered off, the operating handle 311 rotates in the opposite direction under the rebound effect of the torsion spring, and the locking tongue 312 is re-engaged in the locking groove 2 and re-locked, see Figure 3 and Figure 4 .

[0090] Before leaving the factory, the vehicle needs to be tested to see if it meets the safety test requirements of E-NCAP (European New Car Assessment Programme) and C-NCAP (China New Car Assessment Program). Figure 7In the vehicle test, the impact from the front of the vehicle is the largest, followed by the side impact, and the impact from the rear is the smallest, that is, the impact force on the front of the vehicle is the largest, and the impact force on the rear of the vehicle is the smallest. In the vehicle using the utility model, the unlocking mechanism 3 and the locking groove 2 are arranged on the front side of the rotating seat, and the opening of the locking groove 2 faces the front of the vehicle. Since the direction of the impact force on the front side with the largest impact is opposite to the unlocking direction, the locking reliability of the rotating seat is higher and the safety is higher.

[0091] In addition, the electric drive component is used to control the lock component 31, which facilitates the setting of the controller for intelligent control, improves convenience, and adapts to intelligent needs.

[0092] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
