Description

Technical Field

[0001] This utility model belongs to the technical field of seat components, specifically relating to a self-lubricating electric turntable. Background Technology

[0002] Installing a rotating disc under the seat is a common practice. In existing technology, to enable rotation between rotating and non-rotating components on the rotating disc, a planar rotary bearing is used between the rotating and non-rotating components. However, using a planar rotary bearing requires regular lubrication, making maintenance troublesome. Utility Model Content

[0003] This invention proposes a self-lubricating electric turntable that does not require regular lubrication, thereby reducing maintenance difficulty.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a self-lubricating electric turntable, including an upper turntable plate, a turntable mechanism fixing plate, and a lower turntable plate. The turntable mechanism fixing plate is used to press the upper turntable plate onto the lower turntable plate. The upper turntable plate is provided with a rotating mechanism for realizing the rotation of the upper turntable plate relative to the lower turntable plate. At least one rotating support plate is provided between the upper turntable plate and the lower turntable plate, and between the upper turntable plate and the turntable mechanism fixing plate. The rotating support plate is made of a self-lubricating material with self-lubricating function. At least one protrusion is provided on the rotating support plate. The turntable mechanism fixing plate and the lower turntable plate are provided with positioning holes for the protrusion to extend into.

[0005] As a preferred embodiment of the above scheme, the rotating support plate has an oil storage hole on the side away from the protrusion, which corresponds to the position of the protrusion and is used to store solid lubricant.

[0006] In a further preferred embodiment, the rotating support plate has an upward or downward arc-shaped protrusion near the protrusion, and the direction of the arc-shaped protrusion is opposite to that of the protrusion. When there are two or more protrusions on the rotating support plate, the arc-shaped protrusion is located between two adjacent protrusions. When there is only one protrusion on the rotating support plate, arc-shaped protrusions are provided on both sides of the protrusion, and the arc-shaped protrusions are not located on the end of the rotating support plate.

[0007] Further preferably, the width of the protrusion on the rotating support plate is greater than the width of the other positions.

[0008] The beneficial effects of this utility model are as follows: by using a rotating support plate made of self-lubricating material to replace the existing planar rotating bearing, it eliminates the need for regular lubrication. Furthermore, the protrusions and positioning holes not only facilitate installation but also effectively prevent impurities from entering the rotating surfaces from the positioning holes, thereby reducing abnormal noise and extending the service life of the rotating support plate.

[0014] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0015] like Figures 1-4 As shown, a self-lubricating electric turntable mainly consists of an upper turntable plate 10, a turntable mechanism fixing plate 20, a lower turntable plate 30, a rotating mechanism, and at least one rotating support plate 40. The upper turntable plate 10 is used to connect with a seat, the turning mechanism fixing plate 20 is used to press the upper turntable plate 10 onto the lower turntable plate 30, and the lower turntable plate 30 is used to connect the moving parts of the vehicle body or the front and rear sliding rails. A rotating mechanism is provided on the upper turntable plate 10 to realize the rotation of the upper turntable plate 10 relative to the lower turntable plate 30. The rotating mechanism is prior art and can be either stepped or stepless as needed.

[0016] At least one rotating support plate 40 is provided between the upper plate 10 and the lower plate 30 of the turntable, and between the upper plate 10 and the fixed pressure plate 20 of the turntable mechanism. The rotating support plate 40 is made of a self-lubricating material with self-lubricating function, so that it has its own lubrication effect and thus reduces the coefficient of friction. For example, aluminum alloy-based self-lubricating material, rubber-based self-lubricating material, polyetheretherketone + carbon fiber, copper-based self-lubricating material, and graphite. Among them, aluminum alloy-based self-lubricating material has the characteristics of light weight, rubber-based self-lubricating material can absorb impact, and polyetheretherketone + carbon fiber has a wide applicable temperature range. Therefore, different materials can be selected as needed to maximize the performance of the corresponding electric turntable.

[0017] To facilitate the installation of the rotating support plate, at least one protrusion 41 is provided on the rotating support plate 40. Correspondingly, positioning holes for the protrusion to extend into are provided on the turntable mechanism fixing plate 20 and the turntable lower plate 30, so that after installation, the protrusion located between the turntable upper plate 10 and the turntable lower plate 30 faces downward, and the protrusion located between the turntable upper plate 10 and the turntable mechanism fixing plate 20 faces upward.

[0018] The rotating support plates are configured as needed. When there is one rotating support plate 40 located between the upper plate 10 and the lower plate 30 of the turntable, the rotating support plate 40 is set as an annular shape. When there are two or more rotating support plates 40, the rotating support plates 40 are set as arc-shaped shapes. Preferably, there are four rotating support plates.

[0019] Preferably, an oil storage hole 43 is provided on the side of the rotating support plate 40 away from the protrusion 41, corresponding to the position of the protrusion 41 and used to store solid lubricant, so that the stored solid lubricant can flow out on the surface with relative movement, which can further reduce friction. The solid lubricant can be tungsten disulfide, which facilitates continuous lubrication and makes the friction coefficient fluctuation less than 5%.

[0020] Rotary support plates of different thicknesses can be set according to load requirements. The thickness of the rotary support plate is between 0.5-10mm. In order to eliminate the gap caused by the thickness of the lead material, an upward or downward arc protrusion section 42 is provided on the rotary support plate 40 near the protrusion 41, and the orientation of the arc protrusion section 42 is opposite to that of the protrusion 41.

[0021] When there are two or more protrusions 41 on the rotating support plate 40, the arc-shaped protrusion section 42 is located between two adjacent protrusions 41. When there is only one protrusion 41 on the rotating support plate 40, an arc-shaped protrusion section 42 is provided on both sides of the protrusion 41, and the arc-shaped protrusion section 42 is not provided on the end of the rotating support plate 40.

[0022] Preferably, the width of the part on the rotating support plate 40 where the protrusion 41 is provided is greater than the width of the other parts.
