Description

Technical Field

[0001] This utility model relates to the field of electric seat technology, specifically to a shock-absorbing base for an electric car seat. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for driving and riding comfort, car seats have evolved from simple functional components into a key system affecting the overall comfort and luxury of a vehicle. Among them, electric seats have become standard equipment in modern cars, especially mid-to-high-end models, due to their convenient operation and precise position adjustment to fit drivers and passengers of different body types.

[0003] To improve the driving experience, current electric seats generally have a shock-absorbing base at the bottom. The shock-absorbing base mainly uses springs to provide shock absorption. However, after repeated compression over a long period of time, the elasticity of the springs will decrease, thereby reducing the shock absorption effect. Currently, when replacing the springs, the entire electric seat needs to be removed to expose the shock-absorbing base underneath. Furthermore, since the springs need to be pre-compressed during installation to provide the necessary preload, the replacement process must overcome a great deal of elastic force, making spring replacement cumbersome, laborious, and very inconvenient. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a shock-absorbing base for electric car seats.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A shock-absorbing base for an electric car seat includes: a base plate, a support plate, a flip plate, a shock-absorbing mechanism, and a lifting mechanism;

[0007] The load-bearing plate is installed on top of the base plate via a shock-absorbing mechanism;

[0008] The flap is hinged to the upper surface of the support plate;

[0009] The lifting mechanism is installed on the surface of the base plate and is used to lift the support plate upwards;

[0010] The shock absorption mechanism includes a fixed block and a movable block installed on the surface of the base plate. A slide rod is connected between the fixed block and the movable block. A ball bearing sleeve is fitted on the outer surface of the slide rod. A support arm is hinged to the outer surface of the ball bearing sleeve, and the end of the support arm is hinged to the lower surface of the bearing plate. A spring is fitted on the outer surface of the slide rod, and the two ends of the spring abut against the movable block and the ball bearing sleeve, respectively.

[0011] The beneficial effects of this utility model are: by hingedly connecting the flip plate and the support plate, when replacing the spring, the support plate can be exposed simply by flipping the electric seat, without the need to disassemble the electric seat as a whole. Furthermore, the lifting mechanism can lift the support plate upwards to release the pressure it exerts on the spring, thus eliminating the need to apply an initial preload when replacing the spring, making spring replacement simpler, easier, and more convenient.

[0012] Furthermore, the movable block is mounted on the surface of the base plate by a second bolt. The surface of the movable block has insertion holes. One end of the sliding rod is connected to the fixed block, and the other end of the sliding rod is inserted into the insertion hole. The insertion hole provides support for the other end of the sliding rod, improving its structural robustness and preventing structural damage or deformation.

[0013] Furthermore, the lifting mechanism includes a stud mounted on the surface of the base plate. An internally threaded sleeve is installed on the outer surface of the stud, and multiple levers are distributed in a circular array on the outer surface of the internally threaded sleeve. When the internally threaded sleeve is rotated, it can be raised and lowered on the stud, thereby lifting the support plate.

[0014] Furthermore, a support block is rotatably mounted on the top of the internal threaded sleeve, corresponding to the center of the support plate. This prevents rotational friction on the bottom of the support plate when it is lifted, thus avoiding wear.

[0015] Furthermore, hydraulic damping rods are installed at the four corners of the base plate surface, with the telescopic ends of the hydraulic damping rods connected to the bottom of the bearing plate. This provides damping and ensures stable vibration reduction.

[0016] Furthermore, the surface of the support plate is provided with two operating ports, symmetrically distributed on both sides of the support block. This allows for spring replacement from above, ensuring unrestricted operating space.

[0017] Furthermore, the side of the flap furthest from the hinge is connected to the support plate via a first bolt. Connecting the flap to the support plate with the first bolt ensures the overall structural integrity. Attached Figure Description

[0030] Example 1

[0031] Figure 1 This utility model provides a structural diagram of a shock-absorbing base for an electric car seat. Figure 2 This is a schematic diagram of the hidden flap of this utility model. Figure 3 This is a partial cross-sectional structural diagram of the present invention. Figure 4 This is a side sectional view of the present invention. Figures 1 to 4 As shown, the device includes: a base plate 1, a bearing plate 2, a flip plate 3, a shock absorption mechanism 4, and a lifting mechanism 5;

[0032] The bearing plate 2 is installed above the base plate 1 via the shock absorption mechanism 4;

[0033] Flip plate 3 is mounted on the upper surface of the support plate 2 via a hinge.

[0034] Lifting mechanism 5 is installed on the surface of the base plate 1 and is used to lift the bearing plate 2 upward.

[0035] The shock absorption mechanism 4 includes a fixed block 401 and a movable block 402 mounted on the surface of the base plate 1. A slide rod 403 is connected between the fixed block 401 and the movable block 402. A ball bearing sleeve 404 is fitted on the outer surface of the slide rod 403. A support arm 406 is hinged to the outer surface of the ball bearing sleeve 404. The end of the support arm 406 is hinged to the lower surface of the bearing plate 2. A spring 405 is fitted on the outer surface of the slide rod 403. The two ends of the spring 405 abut against the movable block 402 and the ball bearing sleeve 404, respectively.

[0036] The electric seat is mounted on the surface of the flip plate 3. When the vehicle vibrates during driving, the support plate 2 moves downward, pushing the ball bearing sleeve 404 to slide on the slide rod 403 via the spring 405. This compresses the spring 405, using its elastic deformation to achieve shock absorption. When the elastic performance of the spring 405 decreases and needs to be replaced, since the flip plate 3 is hinged to the support plate 2, the support plate 2 can be exposed simply by flipping the electric seat, without the need for complete disassembly of the electric seat. Then, the lifting mechanism 5 lifts the support plate 2 upward, relieving the pressure on the spring 405. The movable block 402 can then be removed to replace the spring 405. This eliminates the need to apply initial preload when replacing the spring 405, making the replacement simpler, easier, and more convenient.

[0037] Figure 5 This is a schematic diagram of the movable block in this utility model. Figure 5 As shown, the movable block 402 is mounted on the surface of the base plate 1 by the second bolt 4022. The surface of the movable block 402 is provided with an insertion hole 4021. One end of the slide rod 403 is connected to the fixed block 401, and the other end of the slide rod 403 is inserted into the insertion hole 4021.

[0038] After removing the second bolt 4022, slide the movable block 402 horizontally to pull the end of the slide rod 403 out of the insertion hole 4021. Then the spring 405 can be replaced. Finally, put the insertion hole 4021 back onto the end of the slide rod 403 to provide support, and tighten the second bolt 4022 again.

[0039] Figure 3 This is a partial cross-sectional structural diagram of the present invention. Figure 4 This is a side sectional view of the present invention. Figure 3 , Figure 4 As shown, the lifting mechanism 5 includes a stud 501 mounted on the surface of the base plate 1. An internal threaded sleeve 502 is mounted on the outer surface of the stud 501, and multiple levers 503 are distributed in a ring array on the outer surface of the internal threaded sleeve 502. A support block 504 is rotatably mounted on the top of the internal threaded sleeve 502, and the support block 504 corresponds to the middle position of the bearing plate 2.

[0040] When the lever 503 is turned to rotate the internal threaded sleeve 502, the internal threaded sleeve 502 can rise under the action of the threaded connection, and lift the bearing plate 2. Furthermore, through the setting of the support block 504, the support block 504 can remain stationary with the bearing plate 2 during the rotation of the internal threaded sleeve 502, thus avoiding wear on the bottom of the bearing plate 2.

[0041] Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a structural schematic diagram of the hidden flap of this utility model. Figure 1 , Figure 2 As shown, hydraulic damping rods 101 are installed at the four corners of the base plate 1, and the ends of the extension and retraction of the hydraulic damping rods 101 are connected to the bottom of the bearing plate 2.

[0042] When the load-bearing plate 2 is raised or lowered, the hydraulic damping rod 101 provides damping effect, consumes the elastic potential energy of the spring 405, thereby suppressing the repeated bouncing of the spring 405 and ensuring the stability of the shock absorption.

[0043] Example 2

[0044] Based on Embodiment 1, the present invention can be further improved in the following ways, such as... Figure 1 , Figure 2 As shown, the surface of the support plate 2 is provided with two operating ports 201, which are symmetrically distributed on both sides of the support block 504. The side of the flip plate 3 away from the hinge is connected to the support plate 2 by the first bolt 301.

[0045] Because the electric seat has limited space on both sides of the vehicle interior, making it inconvenient to operate, the operating port 201 allows for the replacement of the spring 405 from above, thus freeing up operating space. The flip plate 3 is connected to the support plate 2 by the first bolt 301, ensuring the overall structural integrity. Furthermore, the first bolt 301 is located at the front of the electric seat, facilitating easy assembly and disassembly.
