Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding positioning equipment technology, and in particular to a welding positioning mechanism for a car seat headrest music bracket. Background Technology
[0002] Car seats are designed according to ergonomic principles to provide appropriate support for the waist, back, hips, and legs, reducing fatigue while driving or riding. With the rapid development of automobiles, interior functions are becoming more and more numerous and intelligent, aiming to provide passengers with a richer driving and riding experience, such as: built-in displays, wireless charging, intelligent interaction, audio systems, etc.
[0003] As for the audio system, speakers are integrated into the headrests or seat interiors to provide passengers with an independent audio playback experience. This allows passengers in different seats to listen to different music or programs according to their preferences without interfering with each other. Some high-end models also feature seat vibration functionality; when music or videos are played, the seat vibrates slightly in sync with the audio rhythm, enhancing the immersive entertainment experience.
[0004] To enhance this functionality, music mounts are typically added to the headrest or seat to house components such as speakers. See also Figure 1 The music bracket 10 includes a mounting plate 11 and a support plate 12 fixedly mounted on the mounting plate 11. The mounting plate 11 has nut holes 11a for mounting music accessories. During installation, the mounting plate 11 of the music bracket 10 is fixed to the connecting short tube 21 of the car seat headrest frame 20 by welding. The current practice is to manually position the music bracket 10 before welding. This method is prone to inaccurate positioning, resulting in the music bracket 10 not being installed properly, which affects the installation of the seat headrest.
[0005] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0029] See Figures 2 to 6 The figure shows a welding positioning mechanism for a car seat headrest music bracket, including a welding positioning seat 100, a positioning pin assembly 200, and a clamping assembly 300.
[0030] The welding positioning seat 100 has a rectangular structure, and its top surface has a placement plane 110 for placing the music stand 10.
[0031] The positioning pin assembly 200 positions the music holder 10 placed on the placement plane 110 using positioning pins. Specifically, the positioning pin assembly 200 includes a positioning pin 210 and a positioning pin drive cylinder 220. A positioning pin through hole 120 communicating with the placement plane 110 is provided in the welding positioning seat 100, and the positioning pin 210 is disposed within the positioning pin through hole 120. The positioning pin drive cylinder 220 is located below the welding positioning seat 100, and its output end is connected to the lower end of the positioning pin 210 via a clearance connecting block 221, for driving the positioning pin 210 to extend or retract into the positioning pin through hole 120.
[0032] The clamping assembly 300 is used to clamp the music holder 10 positioned on the placement plane 110. Specifically, the clamping assembly 300 includes a clamping cylinder 310, left and right clamping jaws 320a and 320b, and left and right hinges 330a and 330b. The clamping cylinder 310 is located below the welding positioning seat 100. The middle parts of the left and right clamping jaws 320a and 320b are rotatably and symmetrically arranged in the welding positioning seat 100. One end of the left and right hinges 330a and 330b is hinged to the lower end of the left and right clamping jaws 320a and 320b, and the other end is hinged to the end of the output end of the clamping cylinder 310.
[0033] The working principle of the welding positioning mechanism of the car seat headrest music bracket of this utility model is as follows:
[0034] First, the car seat headrest frame 20 is fixed, and the positioning pin 210 is driven out of the positioning pin through hole 120 by the positioning pin drive cylinder 220. Then, the music bracket 10 is placed on the placement plane 110 of the welding positioning seat 100, so that the positioning pin 210 is inserted into the nut hole of the music bracket 10, thereby positioning the music bracket 10. Next, the clamping cylinder 310 drives the left and right clamping jaws 320a and 320b to move through the left and right hinges 330a and 330b, so that the left and right clamping jaws 320a and 320b clamp the support plate of the music bracket 10, thereby clamping and fixing the music bracket 10 to prevent the music bracket 10 from moving during the welding process. At this time, the welding program is started, and the welding robot arm welds the clamped and fixed music bracket 10 to the car seat headrest frame 20. After welding is completed, the positioning pin 210 is retracted into the positioning pin through hole 120 by the positioning pin drive cylinder 220, and the left and right clamping claws 320a and 320b are opened by the clamping cylinder 310, and then the car seat headrest frame 20 with the music bracket 10 welded on is removed.
[0035] This invention precisely positions and clamps the music stand placed on the welding positioning seat, preventing it from moving during welding, reducing the defect rate, ensuring welding quality, and improving production efficiency.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
