Description

Technical Field

[0001] This utility model relates to the field of automotive seat accessories technology, and more specifically, to an anti-detachment automotive seat ball bearing retainer. Background Technology

[0002] Car seats typically feature multi-directional adjustment to meet the needs of different drivers and passengers. The ball bearing retainer is a key component in the car seat adjustment mechanism. Its main function is to position and effectively limit the ball bearings, ensuring that the ball bearings can roll along a predetermined trajectory during seat adjustment, thereby achieving smooth and stable seat adjustment.

[0003] Currently, the design of existing car seat ball bearing retainers is relatively traditional, mostly employing a single-plate structure or a simple double-plate design. While these can meet basic seat adjustment needs to a certain extent and maintain basic ball bearing operation under normal usage scenarios, when car seats undergo frequent adjustments or bear heavy loads, the insufficient strength of existing ball bearing retainer structures can cause ball bearings to shift or fall out. This can lead to jamming and unevenness during seat adjustments, severely affecting the normal function of the seat and reducing the overall safety and reliability of the car seat. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an anti-detachment car seat ball bearing retainer, which aims to solve to some extent the technical problem in the prior art where, when the seat is frequently adjusted or subjected to a large load, the ball bearings are prone to shifting or falling off due to insufficient structural strength of the retainer. This can easily lead to jamming and unevenness during seat adjustment, seriously affecting the normal use of the seat and reducing the overall safety and reliability of the car seat.

[0005] The technical solution of this utility model is as follows: an anti-detachment car seat ball bearing retainer, including an inner retaining plate, an outer retaining plate and a plurality of balls. The inner retaining plate has a plurality of pressure holes at two bends on its inner wall, and the outer retaining plate has a plurality of support holes at two bends on its inner wall. The balls are rotatably connected in the pressure holes and support holes, and the pressure holes and support holes can limit the movement of the balls. The inner retaining plate is fixedly connected to the outer retaining plate.

[0006] Preferably, the retainer further includes a plurality of first fastening bolts, the inner wall of the inner retaining plate has a plurality of first mounting holes, the inner wall of the outer retaining plate has a plurality of second mounting holes, and the first fastening bolts pass through the first mounting holes and the second mounting holes to connect the inner retaining plate and the outer retaining plate.

[0007] Preferably, the inner wall of the inner retaining plate has two first limiting protrusions, and the outer wall of the outer retaining plate has two slots, with the first limiting protrusions engaging with the slots.

[0008] Preferably, both the inner retaining plate and the outer retaining plate have multiple reserved holes on their outer walls, and the multiple reserved holes are distributed in a linear and equidistant structure.

[0009] Preferably, the inner retaining plate has a first limiting protrusion protruding outward at both ends of the bending angle, and the outer retaining plate has a third limiting groove recessed inward at both ends of the bending angle, with the first limiting protrusion and the third limiting groove engaging.

[0010] Preferably, the inner retaining plate is provided with a first limiting groove at both ends, and the outer retaining plate is provided with a first protrusion at both ends, the first protrusion engaging with the first limiting groove.

[0011] Preferably, the inner retaining plate is provided with a second limiting groove at both ends, and the outer retaining plate is provided with a second protrusion at both ends, the second protrusion engaging with the second limiting groove.

[0012] Preferably, the inner wall of the outer retaining plate is provided with a fourth limiting groove, and the second mounting hole and the reserved hole are both located in the fourth limiting groove.

[0013] Preferably, the retainer further includes two second fastening bolts, which pass through the first mounting hole on the inner retaining plate and the second mounting hole on the outer retaining plate, respectively, and a limit plate is fixedly connected to the outer wall of the outer retaining plate.

[0014] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0015] 1. By opening pressure holes and support holes at the bending angles of the inner and outer retaining plates respectively, the balls are limited and securely fixed, which not only prevents the balls from shifting and falling off during the sliding process, but also improves the smoothness and safety of the slide rail.

[0016] 2. The engagement between the first limiting protrusion and the slot serves a positioning function, enhancing the horizontal connection between the inner and outer retaining plates during seat operation and preventing misalignment under lateral forces. When the seat is adjusted left or right or subjected to lateral impact forces, the engagement between the first limiting protrusion and the slot restricts the lateral movement of the inner and outer retaining plates, ensuring that the normal operating trajectory of the ball bearings is not affected and improving the stability of the retainer structure.

[0022] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-4 A type of anti-detachment car seat ball bearing retainer includes an inner retaining plate 1, an outer retaining plate 2, and multiple balls 3. The inner retaining plate 1 has multiple pressure holes 105 at two bends on its inner wall, and the outer retaining plate 2 has multiple support holes 208 at two bends on its inner wall. The balls 3 are rotatably connected within the pressure holes 105 and the support holes 208. The pressure holes 105 and the support holes 208 can limit the balls 3 and prevent them from falling out of the pressure holes 105 and the support holes 208. The inner retaining plate 1 is fixedly connected to the outer retaining plate 2.

[0024] The pressure hole 105 at the bend angle of the inner wall of the inner retaining plate 1 and the support hole 208 at the bend angle of the inner wall of the outer retaining plate 2 limit the movement of the ball 3, improving the stability of the ball 3 during operation. This avoids the ball 3 from shifting due to seat adjustment or load changes, ensuring smooth operation of the slide rail.

[0025] The inner retaining plate 1 is fixedly connected to the outer retaining plate 2, forming a stable frame structure, which enhances the overall strength of the retainer. When the seat bears a large load, the inner retaining plate 1 and the outer retaining plate 2 can share the pressure together, preventing the retainer from deforming or being damaged due to excessive local stress.

[0026] The retainer also includes multiple first fastening bolts 4, multiple first mounting holes 106 are provided on the inner wall of the inner retaining plate 1, and multiple second mounting holes 206 are provided on the inner wall of the outer retaining plate 2. The first fastening bolts 4 pass through the first mounting holes 106 and the second mounting holes 206 to connect the inner retaining plate 1 and the outer retaining plate 2.

[0027] Multiple first fastening bolts 4 pass through the first mounting hole 106 and the second mounting hole 206, tightly connecting the inner retaining plate 1 and the outer retaining plate 2 together. This connection method improves the fastening force and enhances the connection stability between the inner retaining plate 1 and the outer retaining plate 2.

[0028] The inner wall of the inner retaining plate 1 has two first limiting protrusions 104, and the outer wall of the outer retaining plate 2 has two slots 205. The first limiting protrusions 104 and the slots 205 are engaged and cooperated.

[0029] The engagement of the first limiting protrusion 104 with the slot 205 serves a positioning function, enhancing the horizontal connection between the inner retaining plate 1 and the outer retaining plate 2 during seat operation and preventing misalignment under lateral forces. When the seat is adjusted left or right or subjected to a lateral impact force, the engagement of the first limiting protrusion 104 with the slot 205 restricts the lateral movement of the inner retaining plate 1 and the outer retaining plate 2, ensuring that the normal operating trajectory of the ball bearings 3 is not affected and improving the stability of the retainer structure.

[0030] Both the inner retaining plate 1 and the outer retaining plate 2 have multiple reserved holes 6 on their outer walls, and the multiple reserved holes 6 are distributed in a linear and equidistant structure.

[0031] The inner retaining plate 1 has a first limiting protrusion 101 protruding outward at both ends of the bending angle, and the outer retaining plate 2 has a third limiting groove 203 recessed inward at both ends of the bending angle. The first limiting protrusion 101 and the third limiting groove 203 engage with each other. The above structural design can prevent the inner retaining plate 1 and the outer retaining plate 2 from relative displacement at the ends, improving the integrity and stability of the retainer structure. When the seat is subjected to a large torsional force, the engagement of the first limiting protrusion 101 and the third limiting groove 203 can limit the relative rotation of the inner retaining plate 1 and the outer retaining plate 2, ensuring the normal operation of the ball bearing 3.

[0032] The inner retaining plate 1 has a first limiting groove 102 at both ends, and the outer retaining plate 2 has a first protrusion 201 at both ends. The first protrusion 201 is engaged with the first limiting groove 102.

[0033] The inner retaining plate 1 has a second limiting groove 103 at both ends, and the outer retaining plate 2 has a second protrusion 202 at both ends. The second protrusion 202 is engaged with the second limiting groove 103.

[0034] The engaging engagement between the first protruding plate 201 and the first limiting groove 102, and the engaging engagement between the second protruding plate 202 and the second limiting groove 103, limit and fix the inner retaining plate 1 and the outer retaining plate 2 from different angles. This enhances the connection strength between the inner retaining plate 1 and the outer retaining plate 2, and improves the reliability of the retainer structure.

[0035] The inner wall of the outer retaining plate 2 is provided with a fourth limiting groove 204, and the second mounting hole 206 and the reserved hole 6 are both located in the fourth limiting groove 204.

[0036] The retainer also includes two second fastening bolts 5, which pass through the first mounting hole 106 on the inner retaining plate 1 and the second mounting hole 206 on the outer retaining plate 2, respectively. A limit plate 207 is fixedly connected to the outer wall of the outer retaining plate 2.

[0037] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
