Description

Technical Field

[0001] The invention belongs to the technical field of automobile seats, and particularly relates to an auxiliary device for moving an automobile seat in and out. Background Art

[0002] Currently, the seat movement mechanisms used in automotive seat testing typically utilize an all-iron structure, making them very heavy. The two parts of the rolling mechanism are separate and disconnected, making them susceptible to falling and injuring the user during use. This lack of connection can easily cause the axles of the front and rear rollers to become misaligned during use, increasing resistance during sliding and hindering testing. Furthermore, to ensure the traction machine has sufficient height to pull the rolling mechanism, the base was previously constructed to a very high height. This also required finding a high drop point for installation, limiting its installation location.

[0003] Therefore, it is necessary to develop a car seat moving-in and moving-out auxiliary device with a compact structure, high operating precision, and unrestricted use site. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and provide an auxiliary device for moving in and out of a car seat to solve the problem of moving in and out of a car seat with high precision and quickly.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0007] Each rolling mechanism includes three sets of rollers, namely support wheels 13 arranged in the left and right slide rails and guide wheels 12 arranged in the guide rail in the middle of the base 2; a slide bar I 10 and a slide bar II 11 are arranged between the two rolling mechanisms, one of which is fixed to the two slide bars, and the other can slide along the two slide bars; a seat clamp can be installed on the two rolling mechanisms, so that the two rolling mechanisms move synchronously along the direction of the slide bars;

[0008] The traction mechanism consists of a rope lifter and a block integrally formed with the rope lifter 3; the rope lifter 3 includes two pulleys and a pulley support seat fixed to the base 2; the traction mechanism is connected to the rolling mechanism through a rope, and a rope traction hole 4 is provided on the rope lifter 3. The rope is connected to the first pulley of the traction mechanism through the rope traction hole 4. When connected, the rope always remains parallel to the direction of operation of the rolling mechanism. The rope then passes around the second pulley. A counterweight is connected to the end of the rope, and the rolling mechanism is moved horizontally along the track direction by gravity.

[0009] Furthermore, the base 2 is made of an aluminum structure, and the right slide rail 1 and the left slide rail 5 are made of steel.

[0010] Furthermore, the first set of rolling mechanisms consists of a front movable rail 6, a pair of support wheels 13 and a guide wheel 12, and the second set of rolling mechanisms consists of a rear slide rail 8, a pair of support wheels 13 and a guide wheel 12. Slide rods I10 and II11 are provided between the front movable rail 6 and the rear slide rail 8.

[0011] Furthermore, the guide wheel 12 is located below the front movable rail 6 and is arranged in the guide rail of the base 2 to adjust the sliding direction of the front movable rail 6.

[0012] Furthermore, the sliding rod I10 and the sliding rod II11 are arranged in the middle position of the front movable rail 6, and are used to connect the front movable rail 6 and the rear sliding rail 8.

The seat clamp is fixed to the rolling mechanism through the screw handle 7, connecting the two sets of rolling mechanisms together and moving synchronously.

[0014] Furthermore, a limiting nail 9 is provided at each of the two corners of the upper surface of the base 2 adjacent to the rear slide rail 8 for limiting the position of the rear slide rail 8.

[0015] Furthermore, the stopper is used to limit the position of the rolling mechanism.

[0016] Furthermore, the bottom of the pulley support seat is fixed to the base 2 by bolts.

[0028] The present invention will be further described below in conjunction with embodiment:

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0031] like Figure 1-Figure 7 As shown, the vehicle seat moving-in and moving-out auxiliary device of the present invention is composed of a base 2, a right slide rail 1, a left slide rail 5, two sets of rolling mechanisms and a traction mechanism.

[0032] The base 2 is responsible for supporting the entire mechanism. The two sets of rolling mechanisms can move freely on the base. The two sets of rolling mechanisms are respectively arranged at the front and rear ends of the base 2. The two sets of rolling mechanisms are connected together by two straight rods. The traction mechanism is fixed on the base 2 and connected to the rolling mechanism through a rope.

[0033] The right slide rail 1 and the left slide rail 5 are respectively fixed to the left and right sides of the base 2 by bolts. The left slide rail 5 and the right slide rail 1 are responsible for supporting the front moving rail 6 and the rear slide rail 8 of the rolling mechanism.

[0034] The base 2 is made of aluminum, and only the left and right slide rails 1 are made of steel, which helps to reduce the weight of the entire mechanism.

[0035] Each set of rolling mechanisms includes three sets of rollers, which are support wheels 13 arranged on the left and right sides and guide wheels 12 arranged in the middle. The rollers on both sides are responsible for supporting the weight of the rolling mechanism and the seat thereon, and the guide wheels 12 in the middle are used to guide and prevent directional deviation during movement.

[0036] Two straight rods, slide bar I 10 and slide bar II 11, are positioned between the two rolling mechanisms. These slide bars are fixed to one rolling mechanism, while the other slides along the two slide bars, ensuring the axes of the two rolling mechanisms remain parallel. The two rolling mechanisms are secured along the slide bars by a seat fixture mounted on them. When the seat fixture is attached to the rolling mechanism, the screw handles 7 on the front moving rail 6 and rear slide rail 8 securely fasten the seat fixture to the rolling mechanism, thus connecting the two rolling mechanisms and enabling them to move synchronously.

[0037] The front rail 6 is equipped with support wheels 13 on its left and right sides, allowing it to slide along the right and left rails 1 and 5. Below the front rail 6 are guide wheels 12, located within the guide rails in the middle of the base 2. These guide wheels 12 are responsible for adjusting the sliding direction of the front rail 6. In the middle of the front rail 6 are slide bars I 10 and II 11, which connect the front rail 6 to the rear rail 8.

[0038] The slide bar I 10 and the slide bar II 11 are rigidly connected to the front movable rail 6 and cannot be moved. There is a slot for installing a seat clamp above the front movable rail 6, and a screw handle 7 is provided in the slot for fixing the seat clamp.

[0039] The rear slide rail 8 has a similar structure to the front movable rail 6, except that the position of the rear slide rail 8 and the slide bars Ⅰ10 and Ⅱ11 is not fixed. The rear slide rail 8 can slide back and forth along the slide bars Ⅱ11 and Ⅰ10 to adapt to the length of the seat clamp installed thereon.

[0040] A limiting nail 9 is provided at each of the two corners of the upper surface of the base 2 adjacent to the rear slide rail 8, which is used to limit the position of the rear slide rail 8 to prevent it from accidentally falling off and injuring people.

[0041] The guide wheels 12 are provided in pairs on the front movable rail 6 and the rear slide rail 8, respectively, and are responsible for guiding the rolling mechanism.

[0042] The support wheels 13 are provided in pairs on the front movable rail 6 and the rear sliding rail 8, respectively, and are responsible for the forward and backward sliding of the rolling mechanism.

[0043] The traction mechanism is composed of a rope lifter and a stopper integrally formed with the rope lifter. The stopper is used to limit the position of the rolling mechanism to prevent the rolling mechanism from accidentally falling.

[0044] The rope lifter 3 includes two pulleys and a pulley support seat, and the bottom of the pulley support seat is fixed to the base 2 by bolts.

[0045] The traction mechanism and the rolling mechanism are connected via a rope. The rope hoist 3 is provided with a pre-set rope traction hole 4 for the rope to pass through. The rope hoist 3 raises the rope to a certain height difference. A weight is attached to the other end of the rope, allowing gravity to move the rolling mechanism along the track. The rope traction hole 4 is aligned with the first pulley on the rope hoist 3, allowing the rope tied to the rope traction hole 4 to pass horizontally over the first pulley on the rope hoist 3.

[0046] Specifically, the rope is connected to the first pulley of the traction mechanism through the rope traction hole 4. During the connection, the rope always remains parallel to the direction of the rolling mechanism. The rope then passes around the second pulley, which is located higher to achieve a certain drop. A counterweight is connected to the end of the rope. The counterweight of appropriate weight drives the rope to move, which in turn drives the rolling mechanism to move horizontally. The horizontal movement of the rolling mechanism drives the seat on it to move horizontally.

[0047] This device is used in seat movement tests and is an important auxiliary tool for this test. The seat is mounted on the front movable rail 6 and rear slide rail 8 via a clamp. The front movable rail 6 and rear slide rail 8 slide together to drive the seat to slide forward and backward. The weight of the counterweight connected to the rope on the rope lifter 3 can be adjusted to meet the test requirements.

[0048] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
