[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0019] AsFigure 1 and Figure 2 As shown in Figure 2 , a mechanism using the repulsive force of magnets to replace buffer nails in an embodiment of the present utility model includes an armrest lower cover 3, an armrest lower cover magnet 2, an armrest base 4, and an armrest base magnet 5. The armrest lower cover 3 is located above the armrest base 4 and is detachably connected to the armrest base 4. The armrest lower cover magnet 2 is arranged in the armrest lower cover 3, and the armrest base magnet 5 is arranged in the armrest base 4. The armrest lower cover magnet 2 and the armrest base magnet 5 are correspondingly distributed, and the armrest lower cover magnet 2 repels the armrest base magnet 5.
[0020] Specifically, the forward direction of the vehicle is the front, and the rear part of the armrest lower cover 3 is rotatably connected to the rear part of the armrest base 4. Secondly, between the armrest lower cover magnet 2 and the armrest base magnet 5, the S poles are opposite to each other, or the N poles are opposite to each other.
[0021] In this embodiment, when the armrest lower cover 3 moves away from the armrest base 4, the armrest lower cover magnet 2 moves away from the armrest base magnet 5. When the armrest lower cover 3 approaches the armrest base 4, the armrest lower cover magnet 2 approaches the armrest base magnet 5. By using the corresponding distribution of the armrest lower cover magnet 2 and the armrest base magnet 5, and the repulsion between the armrest lower cover magnet 2 and the armrest base magnet 5, the armrest base magnet 5 repels the armrest lower cover magnet 2, avoiding direct collision and impact between the armrest lower cover 3 and the armrest base 4, and preventing noise generation.
[0022] Thus, by arranging the armrest lower cover magnet 2 in the armrest lower cover 3 and arranging the armrest base magnet 5 in the armrest base 4, using the repulsive effect between the armrest lower cover magnet 2 and the armrest base magnet 5, the collision between the armrest lower cover 3 and the armrest base 4 can be prevented, and the collision between the armrest lower cover magnet 2 and the armrest base magnet 5 can also be prevented, avoiding damage to the armrest lower cover magnet 2 and the armrest base magnet 5, and ensuring that the armrest lower cover magnet 2 and the armrest base magnet 5 can continuously buffer the armrest lower cover 3 and the armrest base 4.
[0023] Secondly, by arranging the armrest upper cover magnet in the armrest upper cover, the armrest upper cover can be used to protect the armrest upper cover magnet. By arranging the armrest base magnet 5 in the armrest base 4, the armrest base 4 can be used to protect the armrest base magnet 5, further avoiding damage to the armrest lower cover magnet 2 and the armrest base magnet 5, and ensuring that the armrest lower cover magnet 2 and the armrest base magnet 5 can continuously buffer the armrest lower cover 3 and the armrest base 4.
[0024] Optionally, the rear part of the armrest lower cover 3 is connected to the rear part of the armrest base 4. The armrest lower cover magnet 2 is located at the front part of the armrest lower cover 3, and the armrest base magnet 5 is located at the front part of the armrest base 4.
[0025] Specifically, the rear part of the armrest lower cover 3 is rotatably connected to the rear part of the armrest base 4.
[0026] In this embodiment, by arranging the lower armrest cover magnet 2 at the lower end inside the lower armrest cover 3 and arranging the armrest base magnet 5 at the upper end inside the armrest base 4, and using the rear end of the lower armrest cover 3 to be rotatably connected to the rear end of the armrest base 4. When the lower armrest cover 3 approaches the armrest base 4, the lower armrest cover magnet 2 on the lower armrest cover 3 corresponds to the armrest base magnet 5 on the armrest base 4. By utilizing the repulsive property of the armrest base magnet 5 against the lower armrest cover magnet 2, the front part of the lower armrest cover 3 is prevented from colliding and impacting with the front part of the armrest base 4.
[0027] Optionally, the lower armrest cover magnet 2 is snap-fitted onto the lower armrest cover 3, and the armrest base magnet 5 is snap-fitted onto the armrest base 4.
[0028] Specifically, a first insertion groove is formed on the inner bottom surface of the lower armrest cover 3, and the lower armrest cover magnet 2 is correspondingly inserted into the lower armrest cover 3. A second insertion groove is formed on the inner top surface of the armrest base 4, and the armrest base magnet 5 is inserted into the armrest base 4.
[0029] In this embodiment, by connecting the lower armrest cover magnet 2 to the lower armrest cover 3 by a snap-fit method and connecting the armrest base magnet 5 to the armrest base 4 by a snap-fit method, the overall structure of the mechanism using the repulsive force of magnets instead of buffer pins can be reduced, which is beneficial to reducing production costs. Secondly, when the lower armrest cover magnet 2 and the armrest base magnet 5 fail or are damaged, it is convenient to replace them.
[0030] Optionally, as Figure 2 shown, two lower armrest cover magnets 2 are provided, and the two lower armrest cover magnets 2 are located on the left and right sides of the lower armrest cover 3. Two armrest base magnets 5 are provided, and the two armrest base magnets 5 are located on the left and right sides of the armrest base 4. The two lower armrest cover magnets 2 correspond to the two armrest base magnets 5 one by one.
[0031] In this embodiment, by using the rear part of the lower armrest cover 3 to be rotatably connected to the rear part of the armrest base 4, when the front part of the lower armrest cover 3 is docked with the front part of the armrest base 4, the two armrest base magnets 5 and the two lower armrest cover magnets 2 correspondingly generate repulsive forces, so that the left and right sides of the front part of the lower armrest cover 3 are simultaneously subjected to repulsive forces and buffered relative to the left and right sides of the front part of the armrest base 4, which is beneficial to protecting both the left and right sides of the front part of the lower armrest cover 3 and the left and right sides of the front part of the armrest base 4 at the same time.
[0032] Optionally, as Figure 1 and Figure 2 shown, the mechanism using the repulsive force of magnets instead of buffer pins further includes an armrest assembly 1, and the armrest assembly 1 is located at the upper end of the lower armrest cover 3 and is connected to the lower armrest cover 3.
[0033] In this embodiment, by providing the armrest assembly 1 and connecting the upper end of the armrest assembly 1 to the lower armrest cover 3, on the one hand, the lower armrest magnet 2 can be protected by the armrest assembly 1 and the lower armrest cover 3. On the other hand, since the armrest assembly 1 is provided at the upper end of the lower armrest cover 3, it is convenient for a human hand to act on the armrest assembly 1 to drive the lower armrest cover 3 to move relative to the armrest base 4.
[0034] Optionally, as Figure 1 and Figure 2 shown, the mechanism using the repulsive force of magnets instead of buffer pins further includes an armrest mounting skeleton 6. The armrest base 4 is located at the upper end of the armrest mounting skeleton 6 and is connected to the armrest mounting skeleton 6. The armrest assembly 1 is used to be connected to the armrest mounting skeleton 6.
[0035] In this embodiment, when the armrest assembly 1 is actuated to drive the lower armrest cover 3 to move relative to the armrest base 4, by connecting the armrest assembly 1 to the armrest mounting skeleton 6, the direct connection and collision impact between the lower armrest cover 3 and the armrest base 4 can be avoided.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
