Abstract
Description
Technical Field
[0001] This application relates to the field of automotive seat technology, specifically an automotive seat leg rest. Background Technology
[0002] Car seats are vehicle components that passengers come into direct contact with while riding, and they directly affect passenger comfort.
[0003] Existing car seats typically feature power leg rests near the legs to provide support and alleviate fatigue. However, due to their proximity to the legs, these rests are frequently subjected to friction when retracted. Over time, this friction can cause damage to the leg rests, necessitating replacement. Leg rests are usually secured to a mounting bracket with bolts, and the bracket drives the leg rest's rotation. However, the connection between the mounting bracket and the car seat, and the proximity of the seat to the floor, makes it difficult to remove the bolts. Using a screwdriver for bolt removal is inconvenient and hinders the quick replacement of the leg rest.
[0004] Therefore, this application provides a car seat leg rest to solve the above problems. Utility Model Content
[0005] This application provides a car seat leg rest, which aims to solve the problems mentioned in the background art, such as the fact that existing leg rests are usually fixed to the mounting bracket with bolts, but the mounting bracket is connected to the car seat and the seat is close to the floor of the car. Therefore, when removing the bolts between the leg rest and the mounting bracket, the operating space is small, and it is not convenient to remove the bolts with a screwdriver, which affects the quick replacement of the leg rest.
[0006] To achieve the above objectives, this application provides the following technical solution: a car seat leg rest, including a leg pillow and a mounting bracket disposed at the bottom end of the leg pillow for mounting the leg pillow;
[0007] To facilitate the assembly and disassembly of the leg pillow and mounting bracket: a limiting plate is provided at the bottom of the mounting bracket to restrict the movement of the mounting bracket; a connecting component is inserted inside the limiting plate for fixed connection with the leg pillow; the connecting component includes an insert rod inserted inside the limiting plate for mounting the limiting plate, a threaded rod fixedly provided at the end of the insert rod facing the leg pillow for connection with the leg pillow, a blocking block provided outside the insert rod for restricting the rotation of the limiting plate, a mounting block fixedly provided on the outer wall of the insert rod for mounting the blocking block, and a control component inserted inside the insert rod for moving the blocking block. By threading the threaded rod through the threaded hole and the through hole, with the limiting plate parallel to the through hole, the connecting assembly is fixedly connected to the leg rest. Then, the threaded rod and the limiting plate are passed through the through hole, positioning the limiting plate on the side of the mounting bracket away from the leg rest. Rotating the limiting plate causes it to shift position relative to the through hole. The rebound force of the friction strip reduces the wobbling between the mounting bracket and the limiting plate. Simultaneously, the friction strip increases the contact area between the limiting plate and the mounting bracket. The friction between them prevents the limiting plate from rotating arbitrarily. At this time, under the action of the spring's restoring force, the blocking block pushes the linkage plate to drive the blocking block out of the first insertion hole, thereby preventing the limiting plate from rotating and preventing the limiting plate from coinciding with the through hole. This achieves a stable connection between the leg pillow and the mounting bracket. At the same time, when replacing the leg pillow, simply press the pressing block and rotate the limiting plate to coincide with the through hole to move the leg pillow away from the mounting bracket, achieving quick disassembly of the leg pillow, which is beneficial for operation in places with limited space.
[0008] Preferably, to facilitate the installation of the leg pillow and the mounting bracket: the bottom end of the mounting bracket has a through hole for inserting the insert rod, and the bottom end of the leg pillow has a threaded hole for threadedly inserting the threaded rod. The end of the insert rod facing the leg pillow is fixedly connected to the end of the threaded rod away from the leg pillow. By threading the threaded rod to the threaded hole, the connecting assembly is fixedly connected to the leg pillow. Then, by inserting the insert rod through the through hole via the limiting plate and rotating the limiting plate, the connection between the leg pillow and the mounting bracket is completed.
[0009] Preferably, the through hole is an oblong hole.
[0010] Preferably, to facilitate the rotation of the limiting plate: the outer wall of the insert rod has an annular groove for mounting the limiting plate, and the top of the limiting plate has a circular hole. The annular groove and the circular hole allow the limiting plate to rotate in a plane outside the insert rod.
[0011] Preferably, to facilitate the restriction of rotation of the limiting plate: one end of the mounting block is fixedly connected to the outer wall of the insert rod; the insert rod and the mounting block have internal movable cavities for mounting the control component; the movable cavities have first insertion holes on both sides away from the threaded rod end for inserting the blocking block. The blocking block extends out of the first insertion hole, thereby preventing the limiting plate from rotating and avoiding the limiting plate from coinciding with the through hole.
[0012] Preferably, to facilitate control of the blocking block: the control component includes a linkage plate fixedly connected to the end of the blocking block near the threaded rod for moving the blocking block, a pressing block fixedly connected to the end of the linkage plate facing the blocking block for manual pressing, and a spring disposed on the end of the linkage plate away from the blocking block for pushing the linkage plate. A second insertion hole for inserting the pressing block is provided in the middle of the moving cavity at the end away from the threaded rod. By pressing the pressing block, the blocking block can be moved into the moving cavity by driving the linkage plate, causing the limiting plate to rotate. When the pressing block is released, the spring's restoring force pushes the linkage plate, causing the blocking block to extend and restricting the rotation of the limiting plate.
[0013] Preferably, to prevent the limiting plate from rotating freely, a friction strip is fixedly connected to the side of the limiting plate facing the threaded rod. The friction strip increases the friction between the limiting plate and the mounting bracket, thereby restricting the free rotation of the limiting plate.
[0014] This application utilizes a design of a limiting plate, connecting components, and friction strips. A threaded rod is threaded into a threaded hole, and an insert rod is inserted into a through hole. The limiting plate remains parallel to the through hole, thus securing the connecting component to the leg rest. The insert rod and limiting plate are then passed through the through hole, positioning the limiting plate on the side of the mounting bracket away from the leg rest. Rotation of the limiting plate causes it to shift away from the through hole. The friction strip's rebound force reduces wobbling between the mounting bracket and the limiting plate. Simultaneously, the friction strip increases friction between the limiting plate and the mounting bracket, preventing the limiting plate from rotating arbitrarily. A blocking block, under the spring's restoring force, pushes a linkage plate, causing the spring to extend from the first insertion hole, thus preventing the limiting plate from rotating and coinciding with the through hole. This ensures a stable connection between the leg rest and the mounting bracket. Furthermore, leg rest replacement is simple: pressing the pressing block and rotating the limiting plate to align with the through hole moves the leg rest away from the mounting bracket, allowing for quick disassembly and operation in confined spaces.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] This embodiment provides a car seat leg rest, such as Figure 1-7 As shown, the leg rest includes a leg pillow 1 and a mounting bracket 2 disposed at the bottom of the leg pillow 1 for mounting the leg pillow 1;
[0026] To facilitate the assembly and disassembly of the leg pillow 1 and the mounting bracket 2: a limiting plate 3 is provided at the bottom of the mounting bracket 2 to restrict the movement of the mounting bracket 2; a connecting component 4 is inserted inside the limiting plate 3 for fixed connection with the leg pillow 1; the connecting component 4 includes an insert rod 41 inserted inside the limiting plate 3 for mounting the limiting plate 3; a threaded rod 42 fixedly provided at the end of the insert rod 41 facing the leg pillow 1 for connection with the leg pillow 1; a blocking block 43 provided outside the insert rod 41 for restricting the rotation of the limiting plate 3; a mounting block 44 fixedly provided on the outer wall of the insert rod 41 for mounting the blocking block 43; and a control component 45 inserted inside the insert rod 41 for moving the blocking block 43. By threading the threaded rod 42 into the threaded hole and the insertion rod 41 into the through hole, the limiting plate 3 remains parallel to the through hole, thus completing the fixed connection between the connecting assembly 4 and the leg pillow 1. Then, the insertion rod 41 and the limiting plate 3 are passed through the through hole, so that the limiting plate 3 is located on the side of the mounting bracket 2 away from the leg pillow 1. At this time, the limiting plate 3 is rotated, and the limiting plate 3 and the through hole are staggered. Under the action of the rebound force of the friction strip 5, the shaking between the mounting bracket 2 and the limiting plate 3 is reduced. At the same time, the friction strip 5 can increase the friction between the limiting plate 3 and the mounting bracket 2. To prevent the limiting plate 3 from rotating arbitrarily, the blocking block 43, under the restoring force of the spring 453, pushes the linkage plate 451 to extend the blocking block 43 out of the first insertion hole, thereby preventing the limiting plate 3 from rotating and avoiding the limiting plate 3 from coinciding with the through hole position. This achieves a stable connection between the leg pillow 1 and the mounting bracket 2. At the same time, when replacing the leg pillow 1, simply press the pressing block 452 and rotate the limiting plate 3 to coincide with the through hole position to move the leg pillow 1 away from the mounting bracket 2, achieving quick disassembly of the leg pillow 1, which is beneficial for operation in places with limited space.
[0027] Specifically, to facilitate the installation of the leg pillow 1 and the mounting bracket 2: the bottom end of the mounting bracket 2 has a through hole for inserting the insert rod 41, and the bottom end of the leg pillow 1 has a threaded hole for threadedly inserting the threaded rod 42. The end of the insert rod 41 facing the leg pillow 1 is fixedly connected to the end of the threaded rod 42 away from the leg pillow 1. The through hole is an oblong hole. By threading the threaded rod 42 into the threaded hole, the connecting assembly 4 is fixedly connected to the leg pillow 1. Then, by inserting the insert rod 41 through the through hole via the limiting plate 3 and rotating the limiting plate 3, the connection between the leg pillow 1 and the mounting bracket 2 is completed. The number and position of the through holes and threaded holes correspond to the number and position of the connecting components 4. There are at least four connecting components 4, located at the four corners of the bottom of the leg pillow 1. The threads on the inner wall of the threaded hole mesh with the threads on the outer wall of the threaded rod 42. The threaded rod 42 is welded and fixed to the contact part with the insertion rod 41. The diameter of the insertion rod 41 corresponds to the width of the through hole. The diameter of the threaded rod 42 is smaller than the diameter of the insertion rod 41. The shape of the limiting plate 3 is the same as that of the through hole, but the size of the limiting plate 3 is 0.8 times the size of the through hole.
[0028] More specifically, to facilitate the rotation of the limiting plate 3: the outer wall of the insert rod 41 has an annular groove for mounting the limiting plate 3, and the top of the limiting plate 3 has a circular hole. The annular groove and circular hole allow the limiting plate 3 to rotate planarly outside the insert rod 41. The height of the annular groove is matched to the thickness of the limiting plate 3. The limiting plate 3 consists of two symmetrical parts, each with a semi-circular groove at one opposite end. By inserting the ends with the semi-circular grooves into the annular groove and then welding the contact points of the two parts together, the entire limiting plate 3 is formed, thus enabling the limiting plate 3 to rotate around the insert rod 41.
[0029] Specifically, to facilitate the rotation restriction of the limiting plate 3: one end of the mounting block 44 is fixedly connected to the outer wall of the insert rod 41. The insert rod 41 and the mounting block 44 have internal moving cavities for installing the control component 45. On both sides of the moving cavity away from the threaded rod 42, first insertion holes for inserting the blocking block 43 are respectively provided. The blocking block 43 extends out of the first insertion hole, thereby preventing the limiting plate 3 from rotating and avoiding overlap with the through hole. The vertical cross-section of the moving cavity is cross-shaped. The first insertion holes are located at both ends of the horizontal portion of the moving cavity. The size of the first insertion hole matches the size of the blocking block 43. When the pressing block 452 is pressed, the blocking block 43 can move completely into the mounting block 44. The mounting blocks 44 are symmetrically arranged on both sides of the outer wall of the insert rod 41. The mounting blocks 44 are welded and fixed to the contact points with the insert rod 41. The height of the blocking block 43 can cover the annular groove. After the insert rod 41 is installed, the mounting block 44 is located inside the through hole, thus not affecting the assembly and disassembly of the leg pillow 1 and the mounting bracket 2.
[0030] More specifically, to facilitate the control of the blocking block 43: the control component 45 includes a linkage plate 451 fixedly connected to the end of the blocking block 43 near the threaded rod 42 for moving the blocking block 43, a pressing block 452 fixedly connected to the end of the linkage plate 451 facing the blocking block 43 for manual pressing, and a spring 453 disposed at the end of the linkage plate 451 away from the blocking block 43 for pushing the linkage plate 451. A second insertion hole for inserting the pressing block 452 is opened in the middle of the moving cavity at the end away from the threaded rod 42. By pressing the pressing block 452, the blocking block 43 can be moved into the moving cavity by driving the linkage plate 451, thereby restricting the rotation of the plate 3. When the pressing block 452 is released, the restoring force of the spring 453 pushes the linkage plate 451, causing the blocking block 43 to extend and restricting the rotation of the plate 3. The size of the pressing block 452 is adapted to the size of the second insertion hole. The pressing block 452 is welded and fixed to the contact part of the linkage plate 451. The contact part of the linkage plate 451 is welded to the contact part of the blocking block 43. The linkage plate 451 is inserted through the entire transverse part of the moving cavity, so that the blocking blocks 43 are located on both sides of the end of the linkage plate 451 away from the threaded rod 42. The contact part of the spring 453 with the linkage plate 451 is electric welded. In the moving cavity, due to the restriction of the linkage plate 451 and the transverse part of the moving cavity, the spring 453 is always in a compressed state.
[0031] Specifically, to prevent the limiting plate 3 from rotating arbitrarily, a friction strip 5 is fixedly connected to the side of the limiting plate 3 facing the threaded rod 42. The friction strip 5 increases the friction between the limiting plate 3 and the mounting bracket 2, thereby limiting the rotation of the limiting plate 3. Multiple limiting plates 3 are provided, symmetrically distributed at both ends of the limiting plate 3 facing the threaded rod 42. The friction strip 5 is made of rubber, which can achieve an anti-slip effect between the limiting plate 3 and the mounting bracket 2, and at the same time, it can compress and deform between the limiting plate 3 and the mounting bracket 2, avoiding strong vibration and collision between the limiting plate 3 and the mounting bracket 2.
[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
