Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seats, and in particular relates to an electric rotating disc of an automobile seat which is easy to lock. Background Art

[0002] A car seat turntable refers to a turntable installed under the seat cushion in a car seat. The turntable is used to adjust and rotate the seat, and can make the seat rotate 360°. Car seats with turntables are increasingly in demand in today's luxury cars or business cars. The seat can be rotated and adjusted to welcome guests and face the guests. On the other hand, the front passengers can rotate to the back row to facilitate communication with the back row passengers.

[0003] Currently, electric turntables generally only have locking mechanisms at the design position and the 180° position, and have a single usage scenario. When the seat is rotated to the unlocked position, the electric turntable will shake in the rotation direction due to external force factors, reducing the passenger's riding comfort.

[0004] Therefore, an electric turntable for a car seat which is easy to lock is designed to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide an electric turntable for a car seat that is easy to lock, so as to solve the problem in the prior art that the electric turntable cannot be locked at any position.

[0006] In order to achieve the above object, the utility model provides the following technical solutions:

[0008] Furthermore, a cable is fixedly connected to the driving plate.

[0009] Furthermore, a sliding hole is provided on the chassis, and the support is installed in the sliding hole in a limited sliding manner.

[0010] Further, the driving plate is rotatably mounted on a first side of the chassis, and the tension spring is located on a second side of the chassis.

[0015] In order to make the purpose, technical solution and beneficial effects of the utility model clearer, the utility model is described with the following drawings:

[0016] Figure 1 This is a schematic diagram of the overall structure of the electric turntable according to an embodiment of the utility model;

[0017] Figure 2 The figure is a schematic diagram of the overall structure of the electric turntable according to an embodiment of the utility model.

[0019] like Figures 1-2As shown, the utility model provides an electric turntable for a car seat which is easy to lock, comprising: a chassis 1 and a turntable 2 rotatably mounted on the chassis 1, a driving mechanism 3 for outputting rotational power being mounted on the chassis 1, a driving gear 4 being mounted on the output end of the driving mechanism 3, the driving gear 4 being able to rotate due to the output power of the driving mechanism 3, a connecting plate 5 and a gear ring 6 fixedly connected to the connecting plate 5 being mounted on the turntable 2, the inner ring of the gear ring 6 being meshed with the driving gear 4, two pillars 7 being slidably mounted on the chassis 1, a driven gear 9 being fixedly mounted on the pillar 7, the driven gear 9 being meshed with the gear ring 6, a driving plate 8 being rotatably mounted between the two pillars 7 and abutting against the outer peripheral wall of the pillar 7, a tension spring 11 being mounted between the two pillars 7, when the driving plate 8 is rotated to bring the two pillars 7 closer together, the two driven gears 9 can be meshed to lock the gear ring 6; when the driving plate 8 is rotated to move the two pillars 7 away from each other, the two driven gears 9 can be disengaged to unlock the gear ring 6.

[0020] In this scheme, if Figure 1 When the electric turntable is started, the driving mechanism 3 is started. The driving mechanism 3 is a motor. The driving mechanism 3 drives the active gear 4 to rotate, thereby driving the gear ring 6 to rotate. Since the two driven gears 9 are meshed with the gear ring 6, when the two driven gears 9 are meshed under the action of the tension spring 11, the gear ring 6 cannot rotate. At this time, the electric turntable is in a locked state. When the driving plate 8 is rotated to disengage the two driven gears 9, the active gear 4 can drive the gear ring 6 to rotate. At this time, the electric turntable is in an unlocked state.

[0021] This solution can realize that after the gear ring 6 is rotated to any position by setting two driven gears 9, the gear ring 6 is locked by rotating the driving plate 8, thereby realizing the locking of the electric turntable.

[0022] In an embodiment of the present invention, a cable 10 is fixedly connected to the driving plate 8 , and pulling the cable 10 can cause the driving plate 8 to rotate.

[0023] In this solution, the first end of the cable 10 is connected to the drive plate 8, and the second end of the cable 10 is connected to a driving member (not shown in the figure) that can move the cable 10. The driving member includes but is not limited to a motor, an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The driving member can move the cable 10 to rotate the drive plate 8, thereby achieving quick locking and unlocking and saving manpower.

[0024] In one embodiment of the utility model, a sliding hole (not shown in the figure) is provided on the chassis 1, and the pillar 7 is installed in the sliding hole with limited sliding. The pillar 7 can slide along the sliding hole, and during the sliding process of the pillar 7, the driven gear 9 is always engaged with the gear ring 6.

[0025] In one embodiment of the present invention, the driving plate 8 is rotatably mounted on a first side of the chassis 1 , and the tension spring 11 is located on a second side of the chassis 1 to ensure the compactness of the structure.

[0026] In an embodiment of the present invention, the pull rings at both ends of the tension spring 11 are respectively sleeved on the two pillars 7 and clamped, so as to facilitate the installation and removal of the tension spring 11.

[0027] In one embodiment of the present invention, Figure 2 The driving plate 8 is provided with an arc-shaped notch 801 that matches the outer circumference of the support 7 , and the support 7 abuts against the arc-shaped notch 801 .

[0028] In this solution, an arc-shaped notch 801 is provided to increase the contact area between the support 7 and the driving plate 8 and reduce the force applied to the driving plate 8 .

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
