Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat processing, in particular to a riveting and clamping mechanism for an automobile seat slide rail. Background Art

[0002] A car seat is a seat that you sit on when you are in a car. The slide rail is an important mechanical component on the seat, which is mainly installed under the seat and is used to adjust the front and rear position of the seat. When riveting the car seat slide rail, a clamping mechanism is usually required to clamp and position the seat slide rail, and then the clamped and positioned seat slide rail is riveted. After searching, the patent document with the authorization announcement number CN204799874U announced a car seat slide rail riveting clamping mechanism, including a support, a mounting base and a clamping mechanism, the mounting base is set on the support, the clamping mechanism is set on the mounting base, the clamping mechanism includes two clamping arms arranged opposite to each other, and there is a contoured groove between the two clamping arms, and the contoured groove matches the shape of the car seat slide rail to be clamped. The car seat slide rail riveting clamping mechanism can perform a certain auxiliary positioning function when the slide rail and the seat pan are riveted together by rivets, thereby improving the accuracy and efficiency of riveting.

[0003] In actual operation, it was found that the above-mentioned existing scheme still has at least the following deficiencies: the seat slide rail is clamped and fixed by using a clamping mechanism composed of two clamping arms in conjunction with the use of a contoured groove.

Excessive clamping force can easily cause deformation of the clamped part of the seat slide rail, affecting the clamping quality. In addition, it is not suitable for reliably clamping and positioning seat slide rails of different sizes, and has certain limitations when used. Therefore, we propose a riveted clamping mechanism for automobile seat slide rails to solve the above-mentioned problems. Utility Model Content

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The utility model provides a riveting and clamping mechanism for a car seat slide rail, comprising a front U-shaped clamping seat 1, a rear U-shaped clamping seat 2, an electric hydraulic cylinder 3 and a clamping and fixing assembly, wherein:

[0024] The rear U-shaped clamp seat 2 is located directly behind the front U-shaped clamp seat 1, and the electric hydraulic cylinder 3 is fixedly installed on the front outer wall of the rear U-shaped clamp seat 2. The output shaft end of the electric hydraulic cylinder 3 is fixedly connected to the rear outer wall of the front U-shaped clamp seat 1. The same seat slide rail 4 is placed on the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2. The front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2 cooperate with each other to carry the seat slide rail 4, so as to facilitate the subsequent riveting processing of the seat slide rail 4. The electric hydraulic cylinder 3 is used to adjust the distance between the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2, and is suitable for clamping and positioning seat slide rails 4 of different lengths. Electric telescopic springs are fixedly installed on the inner walls on both sides of the front U-shaped clamp seat 1 and the inner walls on both sides of the rear U-shaped clamp seat 2. Rod 5, the number of clamping and fixing components is set to four groups, and the four groups of clamping and fixing components are respectively arranged at the output shaft ends of the corresponding electric telescopic rods 5. The four groups of clamping and fixing components are used to clamp and position the seat slide 4. The electric telescopic rod 5 is used to linearly adjust the position of the clamping and fixing components. The above-mentioned clamping and fixing components include a fixing seat 6, two slides 9, two springs 10, two splints 11, an air pump 12, an air outlet pipe 13 and a U-shaped air supply pipe 14. The fixing seat 6 is fixedly installed at the output shaft end of the electric telescopic rod 5. A clamping groove 7 is provided on the side of the fixing seat 6 close to the seat slide 4. The top and bottom of the clamping groove 7 are both open structures. One side end of the seat slide 4 extends into the clamping groove 7, and mounting grooves are provided on the inner walls on both sides of the clamping groove 7. 8. The two slides 9 are slidably installed in the corresponding mounting grooves 8. The side walls of the slides 9 are slidably sealed with the inner walls of the mounting grooves 8 to ensure that the gap between the slides 9 and the inner walls of the mounting grooves 8 will not leak. The ends of the two springs 10 that are away from each other are fixedly connected to the inner walls of the two clamping grooves 7 that are away from each other. The ends of the two springs 10 that are close to each other are fixedly connected to the sides of the two slides 9 that are away from each other. The two splints 11 are fixedly installed on the sides of the two slides 9 that are close to each other. The sides of the two splints 11 that are close to each other extend to the outside of the corresponding mounting grooves 8. The air pump 12 is fixedly installed on the side wall of the fixing base 6 away from the seat slide rail 4.

The two ends of the U-shaped air pipe 14 extend into the corresponding mounting grooves 8 and are respectively located directly above the corresponding springs 10. By utilizing the joint cooperation of the air pump 12, the air outlet pipe 13 and the U-shaped air pipe 14, air can be delivered to the two mounting grooves 8, and then the air pressure can be used to push the two slides 9 to slide toward each other. By utilizing the joint cooperation of the two splints 11, one side end of the seat slide rail 4 can be clamped and fixed, and it can be ensured that the clamped side end of the seat slide rail 4 will not be deformed. By utilizing the elastic force of the spring 10, the slide rail 9 can be controlled to automatically reset.

[0025] In this embodiment, rubber pads 15 are fixedly installed on the side where the two clamps 11 are close to each other. The two rubber pads 15 are in contact with the outer wall and inner wall of the seat slide rail 4 respectively, preventing the clamped part of the seat slide rail 4 from slipping and avoiding damage to the clamped part of the seat slide rail 4.

[0026] In this embodiment, two bleed pipes 16 are fixedly installed on the side wall of the fixing seat 6 away from the seat slide rail 4.

[0027] In this embodiment, a one-way valve is installed in the air outlet pipe 13 to control the one-way flow of air inside the air outlet pipe 13 and prevent backflow.

[0028] In this embodiment, anti-slip pads 18 are fixedly installed on the bottom inner wall of the front U-shaped clamp seat 1 and the bottom inner wall of the rear U-shaped clamp seat 2. The two anti-slip pads 18 are in contact with the bottom outer wall of the seat slide rail 4, increasing the stability of the seat slide rail 4 placed on the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2.

[0029] In this embodiment, it should be noted that the electric hydraulic cylinder 3, the electric telescopic rod 5, the air pump 12, and the electromagnetic air release valve 17 can be purchased on the market. The electric hydraulic cylinder 3, the electric telescopic rod 5, the air pump 12, and the electromagnetic air release valve 17 are equipped with a power supply and a switch. Their control method and wiring method are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0030] Through the above structure, the car seat slide rail riveting clamping mechanism provided by the utility model can, when in use, firmly clamp and position the seat slide rail 4, and can ensure that the clamped part of the seat slide rail 4 will not be deformed, and is suitable for clamping and positioning seat slide rails 4 of different sizes. During specific operation, by controlling the extension of the electric hydraulic cylinder 3, the distance between the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2 can be gradually increased, and by controlling the contraction and reset of the electric hydraulic cylinder 3, the distance between the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2 can be gradually reduced, and then the distance between the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2 can be adjusted, and by controlling the extension of the two electric telescopic rods 5 on the front U-shaped clamp seat 1, the two fixed rods on the front U-shaped clamp seat 1 can be controlled. The spacing between the fixed seats 6 gradually decreases. By controlling the two electric telescopic rods 5 on the front U-shaped clamp seat 1 to retract and reset, the spacing between the two fixed seats 6 on the front U-shaped clamp seat 1 can be controlled to gradually increase, thereby facilitating the adjustment of the spacing between the two fixed seats 6 on the front U-shaped clamp seat 1. Similarly, by controlling the two electric telescopic rods 5 on the rear U-shaped clamp seat 2 to extend or retract and reset, the spacing between the two fixed seats 6 on the rear U-shaped clamp seat 2 can be conveniently adjusted. When the seat slide rail 4 is clamped and fixed, the spacing between the fixed seat 6 on the front U-shaped clamp seat 1 and the fixed seat 6 on the rear U-shaped clamp seat 2 is adjusted to be slightly larger than the length of the seat slide rail 4, and then the two electric telescopic rods 5 on the front U-shaped clamp seat 1 are controlled to The spacing between the two clamping grooves 7 is adjusted to the width of the seat slide 4, and the two electric telescopic rods 5 on the rear U-shaped clamp seat 2 are controlled to adjust the spacing between the two clamping grooves 7 to the width of the seat slide 4. Then, the seat slide 4 is placed between the four fixed seats 6 on the front U-shaped clamp seat 1 and the rear U-shaped clamp seat 2. Next, the electric hydraulic cylinder 3 is controlled to retract and reset, so that the spacing between the fixed seats 6 on the front U-shaped clamp seat 1 and the fixed seats 6 on the rear U-shaped clamp seat 2 gradually decreases until the front end portions of the seat slide 4 are respectively inserted into the two clamping grooves 7 on the front U-shaped clamp seat 1, and the rear end portions of the seat slide 4 are respectively inserted into the two clamping grooves 7 on the rear U-shaped clamp seat 2. The position of the seat slide 4 can be preliminarily clamped and fixed, and then one of them is controlled The air pump 12 is running, and the air discharged by the air pump 12 passes through the air outlet pipe 13 and the U-shaped air supply pipe 14 in turn and enters the two mounting grooves 8 on the fixing seat 6 respectively, so that the air pressure in the two mounting grooves 8 gradually increases. The air pressure can push the two slide plates 9 to slide in the direction of approaching each other, and the two springs 10 are gradually stretched to generate elastic force, so that the distance between the two clamping plates 11 gradually decreases. When the two rubber pads 15 are respectively tightly against the outer wall and the inner wall of the end position of the seat slide rail 4, the air pump 12 is stopped, and the secondary clamping and fixing of the end position of the seat slide rail 4 is completed. According to the above operating steps, the other three air pumps 12 are controlled to operate in turn, and the other three end positions of the seat slide rail 4 can be clamped and fixed for the second time.By simultaneously clamping the ends of the seat rail 4, deformation of the clamped portion of the seat rail 4 can be effectively prevented, ensuring the quality of the clamping and positioning of the seat rail 4. Once the seat rail 4 is clamped and secured, subsequent riveting can be performed. After this process is completed, the air in the mounting groove 8 is exhausted by opening the four electromagnetic air release valves 17. The elastic force of the spring 10 controls the slide plate 9 to automatically reset the clamping plate 11 and rubber pad 15 mounted thereon. The electric hydraulic cylinder 3 is then controlled to extend, gradually increasing the distance between the front U-shaped clamp 1 and the rear U-shaped clamp 2, allowing the seat rail 4 to be removed.
