Description

Technical Field

[0001] This utility model relates to the field of automotive seat adjustment, specifically to a buffer pad for an automotive seat leveling adjuster. Background Technology

[0002] The car seat leveling mechanism is a key device for adjusting the fore-and-aft position of the seat. Its core function is to achieve precise horizontal movement of the seat through mechanical or electric means to meet the needs of drivers and passengers of different sizes for comfortable seating posture and ease of operation. Electric leveling mechanisms, driven by a motor, achieve automated adjustment and offer advantages such as ease of operation, high adjustment precision, and the ability to integrate multiple functions, making them widely used in mid-to-high-end models. Internally, the motor and transmission device work together, using a bidirectional permanent magnet motor or lead screw motor to provide power, which, in conjunction with the transmission lead screw, converts rotational motion into linear motion, achieving precise seat movement. Some models also feature a memory function, allowing multiple preset positions to be stored for quick switching between different driver and passenger positions.

[0003] However, as the leveling adjuster is used for a longer period of time, the lubrication effect of the lead screw decreases, requiring frequent lubrication of the lead screw. However, conventional lubrication requires the complete removal of the seat or a large range of seat adjustments, which is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a buffer pad for a car seat leveling adjuster, which aims to improve the problem that adding lubricating oil requires the complete removal of the seat or a large range of fore-and-aft adjustments, resulting in poor lubrication efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cushioning pad for a car seat leveling device includes a pad body, wherein an outwardly extending ring is provided on the periphery of the pad body, and a clearance channel is provided on the pad body.

[0007] A molding groove is provided on the inner side of the pad body. The molding groove is distributed around the relief channel. An oil inlet channel and a slit are provided in the molding groove located above the relief channel. The oil inlet channel passes through the ring body and is connected to the outside. The slit extends toward the relief channel and is connected to the relief channel. The pad body is a self-sealing pad body.

[0008] Furthermore, the opening direction of the slit is the same as the extension direction of the clearance channel.

[0009] Furthermore, an oil injection groove is also provided in the molding groove. The oil injection groove extends toward the relief channel and is spaced apart from the relief channel. The slit is opened at the bottom of the oil injection groove, and the opening length of the slit is equal to the opening diameter of the oil injection groove.

[0010] Furthermore, an oil-retaining cotton is provided in the molding groove located above the clearance channel.

[0011] Furthermore, the oil inlet channel is located at the top outer side of the forming groove, and the slit is located at the bottom outer side of the forming groove.

[0012] Furthermore, a sealing ring is provided around the opening of the molding groove located above the clearance channel, and the sealing ring extends from the inner side of the pad body to the inner ring surface of the ring body.

[0013] Furthermore, an inclined surface is provided on the inner side of the free end face of the ring body, and the inclined surface is inclined from the outside to the inside toward the buffer pad.

[0014] Furthermore, protrusions are provided on the outer surface of the ring.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. A clearance channel allows the lead screw to pass through. The pad body fits against the side of the transmission component, which then seals the molding groove. A ring is wrapped around the circumference of the transmission component, providing cushioning during its movement. When the seat is stationary, oil is injected into the molding groove through the oil inlet channel. The self-sealing pad body drives the opening and closing of the slot to seal the molding groove, preventing lubricating oil from flowing out. During seat movement, the pad body is compressed, causing the opening to open and allowing lubricating oil to flow out of the molding groove, thus automatically lubricating the lead screw. This ensures smooth seat movement and reduces maintenance frequency by lubricating the lead screw with each seat adjustment, guaranteeing smooth seat movement.

[0017] 2. Due to the large distance between the relief channel and the ring body, and the large thickness of the pad body and the ring body, air holes are easily generated around the relief channel during the molding process. Setting a molding groove around the relief channel effectively reduces the molding difficulty and reduces material usage and saves costs without affecting the cushioning effect of the cushioning pad.

[0031] Example

[0032] Please refer to Figure 1-5As shown, this embodiment provides a cushioning pad for a car seat level adjuster, including a pad body 1, with an outwardly extending ring 2 on the periphery of the pad body 1, and a clearance channel 11 opened on the pad body 1.

[0033] A molding groove 12 is provided on the inner side of the pad body 1. The molding groove 12 is distributed around the relief channel 11. An oil inlet channel 121 and a slit 122 are provided in the molding groove 12 located above the relief channel 11. The oil inlet channel 121 passes through the ring body 2 and is connected to the outside. The slit 122 extends toward the relief channel 11 and is connected to the relief channel 11. The pad body 1 is a self-sealing pad body 1.

[0034] The clearance channel 11 allows the lead screw to pass through. The pad body 1 fits against the side of the transmission component, which then seals the molding groove 12. The ring body 2 is wrapped around the periphery of the transmission component, providing cushioning during its movement. When the seat is stationary, oil is injected into the molding groove 12 through the oil inlet channel 121. The self-sealing pad body 1 drives the slit 122 to close, sealing the molding groove 12 and preventing lubricating oil from flowing out. During seat movement, the pad body 1 is compressed, causing the slit 122 to open and allowing lubricating oil to flow out of the molding groove 12. This achieves automatic lubrication of the lead screw, ensuring smooth seat movement and reducing maintenance frequency by lubricating the lead screw with each seat adjustment.

[0035] Because the gap between the relief channel 11 and the ring body 2 is large, and the thickness of the pad body 1 and the ring body 2 is large, air holes are easily generated around the relief channel 11 during the molding process. The molding groove 12 is set around the relief channel 11 to effectively reduce the molding difficulty and reduce the material usage and save costs without affecting the cushioning effect of the cushioning pad.

[0036] Please refer to Figure 2As shown, an oil-retaining cotton 3 is provided in the molding groove 12 located above the clearance channel 11. The oil-retaining cotton 3 stores lubricating oil. When the car seat is stationary, the lubricating oil is stored in the oil-retaining cotton 3. During the movement of the car seat, the lubricating oil in the oil-retaining cotton 3 is driven to flow out by the inertia of the movement and the collision between the oil-retaining cotton 3 and the pad body 1, passing through the slit 122 to lubricate the lead screw. Furthermore, the oil-retaining cotton 3 reduces the sealing requirements between the molding groove 12 and the transmission component, reducing the probability of lubricating oil flowing out from the opening of the molding groove 12. Further, a sealing ring 4 is provided around the opening of the molding groove 12 located above the clearance channel 11. The sealing ring 4 extends from the inner side of the pad body 1 to the inner ring surface of the ring body 2. The sealing ring 4 is interference-fitted between the buffer pad and the transmission component, using the transmission component to seal the opening of the molding groove 12 located above the clearance channel 11, preventing the lubricating oil in the molding groove 12 from flowing out between the buffer pad and the transmission component, thus affecting the storage of lubricating oil.

[0037] Please refer to Figure 3 and Figure 4 As shown, the oil inlet channel 121 is located at the top outer side of the molding groove 12, and the slit 122 is located at the bottom outer side of the molding groove 12. The oil inlet channel 121 is set at a high position to prevent lubricating oil from accumulating in the molding groove 12 or flowing back along the oil inlet channel 121; the slit 122 is set at a low position so that all the lubricating oil entering the molding groove 12 can flow out along the slit 122.

[0038] Please refer to Figure 5 As shown, in this embodiment, the opening direction of the slit 122 is the same as the extension direction of the clearance channel 11. That is, the opening direction of the slit 122 is the same as the extension direction of the lead screw. During the movement of the seat, the transmission component squeezes one side of the opening of the slit 122 towards the other side, driving the opening to open to a wider range and improving the refueling efficiency. Furthermore, an oil injection groove 123 is also provided in the forming groove 12. The oil injection groove 123 extends toward the clearance channel 11 and is spaced apart from the clearance channel 11. The slit 122 is opened at the bottom of the oil injection groove 123, and the opening length of the slit 122 is equal to the opening diameter of the oil injection groove 123. The lubricating oil that is about to flow out of the molding groove 12 is stored in the oil injection groove 123. During the movement of the seat, the oil injection groove 123 is squeezed, and the lubricating oil in the oil injection groove 123 is driven by the squeeze to move directly through the slit 122 to the lead screw. This increases the acceleration of the lubricating oil when it leaves the slit 122, ensuring that the lubricating oil can be accurately pushed to the lead screw. This avoids the lubricating oil having a low acceleration and not moving to the lead screw, instead flowing along the inner wall of the relief channel 11, which would affect the lubrication effect.

[0039] Please refer to Figure 1-3As shown, an inclined surface 21 is provided on the inner side of the free end face of the ring body 2, and the inclined surface 21 is inclined from the outside to the inside towards the buffer pad. The inclined surface 21 forms disassembly and assembly notches on both sides of the buffer pad, allowing the hand to apply force to the ring body 2, thereby improving the assembly efficiency of the buffer pad. Furthermore, a protrusion 22 is provided on the outer surface of the ring body 2. The protrusion 22 is provided on the outer side of the ring body 2, and without affecting the installation of the buffer pad, it provides a block for the hand to apply force, making it easier to grasp, lift, disassemble, or put down the buffer pad for installation, further improving the disassembly and assembly efficiency of the buffer pad.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
