Description

Technical Field

[0001] The invention relates to the technical field of seat headrest connectors, and in particular to a suspended headrest connector. Background Art

[0002] In order to provide users with a better experience, the existing car seat headrests have introduced multifunctional modules, which can provide massage, heating / cooling, ventilation and multimedia functions. The current connection structures between the headrest and the seat include fixed and plug-in types. Among them, the plug-in type can provide up and down position adjustment function, so the plug-in type structure is also the most widely used.

[0003] Furthermore, the multifunctional headrest also needs to meet the requirement of being removable and replaceable. Therefore, the multifunctional headrest and the seat need to be powered and communicated through a connector. In daily use, the headrest often needs to be adjusted up and down, especially for the co-pilot and rear seats. Therefore, the connector not only needs to meet the requirements of easy disassembly, but also needs to meet the requirements of stable plugging, high reliability and long service life. Most existing plug-in connectors are single buckle structures, which are often easy to press to the bottom when pressed for plugging, resulting in difficulty in controlling the depth and strength of the plugging, and poor user experience and stability.

[0004] Therefore, the connector not only needs to be able to be blindly plugged in, but also needs to have good anti-unplugging capabilities after plugging in. At the same time, it must also be able to ensure that the plug does not unplug when the user adjusts the height of the headrest, and that the plugging is stable (no momentary interruption in power supply), and that the disconnection is convenient and clean.

[0055] After the plug 11 is inserted, the first hook 280 of the clamping member 28 will be engaged with the plug 11, and the terminal 13 will be electrically connected to the female conductive member 26. The first elastic member 22 can be a spring, and the second elastic member 29 can be a U-shaped spring.

[0056] It should be noted that, combined with Figure 6 , Fig.11 As shown, two mounting parts 231 may be symmetrically arranged, and the mounting parts 231 include two partitions. The clamping clamp 28 is installed between the two partitions through the rotating shaft 233. Similarly, two clamping clamps 28 are also arranged; when the second elastic member 29 is a U-shaped spring, the second end of the clamping clamp 28 may be a second hook 281, and the second hook 281 hooks one end of the U-shaped spring; the first magnet 24 is arranged around the outside of the female terminal block 23, and after the sleeve 21 is clamped with the female terminal block 23, the first magnet 24 will be limited and fixed, and the first magnet 24 can also be fixed in the sleeve 21 through other limiting structures.

[0057] It should be pointed out that, combined with Figure 4 , Figure 5 As shown, the female conductive member 26 is provided with two types, one of which is Figure 4 The flat type shown in the figure is in contact with the terminal 13 to achieve electrical conduction. Figure 5 The plug-in type shown is plugged into the terminal 13 to achieve conductivity. Furthermore, the female conductive part 26 can be an existing conductive terminal, so its structure is not described in detail here.

[0058] Specifically, Figure 2 , Figure 3 As shown, the structure of the rod assembly 1 may be as follows: a first groove 100 is provided at the end of the rod 10, a male terminal seat 12 is installed in the mounting hole 110 of the plug 11, and the terminal 13 is installed in the male terminal seat 12;

[0059] The plug 11 is provided with a first slot 112 for engaging with the first hook 280, and the plug 11 is provided with a first side slot 115 and a second side slot 116;

[0060] The male terminal seat 12 is provided with a first mounting protrusion 120 and a second mounting protrusion 121 corresponding to the first side groove 115 and the second side groove 116 respectively;

[0061] After assembly, the first mounting protrusion 120 is inserted into the first side groove 115 and the first groove 100, and the second mounting protrusion 121 is inserted into the second side groove 116;

[0062] The above structure makes it difficult for the male terminal seat 12 to be disengaged upward or downward, thereby ensuring that the male terminal seat 12 can be fully stressed and does not drift during insertion;

[0063] Furthermore, the first side groove 115 and the second side groove 116 are arranged at the filling part 113 (tail end) of the plug, and the outer surface of the filling part 113 may be provided with a friction surface 114, the purpose of which is to improve the connection strength between the plug 11 and the rod body 10, and they are generally interference fit.

[0064] Specifically, combined Figure 1 , Figure 4 As shown, the outer side of the rod sleeve 3 is provided with a buckling protrusion 30 and an anti-fool protrusion 31, and the female head sleeve shell 20 is provided with a clamping groove 201 and an anti-fool groove 200 corresponding to the buckling protrusion 30 and the anti-fool protrusion 31;

[0065] Recombination Fig.15 , Fig.16 As shown, the rod sleeve 3 is provided with a third elastic plate 32, and the buckling protrusion 30 is provided on the third elastic plate 32. During the buckling process, the third elastic plate 32 can be bent inward, thereby avoiding direct hard connection installation.

[0066] Specifically, combined Figure 2 , Fig.11 As shown, a first guide groove 111 is provided on the inner side wall of the mounting hole 110 of the plug 11, and a guide protrusion 230 matching with the first guide groove 111 is provided on the female terminal block 23;

[0067] Combination Fig.16 As shown, the connection structure between the plug 11 and the female terminal block 23 has another embodiment: a second guide protrusion 117 is provided on the inner side wall of the mounting hole 110 of the plug 11, and the female terminal block 23 is provided with a second guide groove 234 cooperating with the second guide protrusion 117; the purpose of both embodiments is to facilitate the insertion and docking of the plug 11 and the female terminal block 23.

[0068] Specifically, combined Figure 6 As shown, the side wall of the sleeve 21 is provided with a first elastic plate 210, the first protrusion 211 is provided on the first elastic plate 210, and the first magnet 24 is provided with a second avoidance groove 240;

[0069] When the first elastic plate 210 is pressed into the inner side of the sleeve 21, the first elastic plate 210 will enter into the second avoidance groove 240;

[0070] The side wall of the sleeve 21 is provided with a second elastic plate 212, the second elastic plate 212 is provided with a second clamping groove 213, the outer side wall of the female terminal block 23 is provided with a second protrusion 232, and the second protrusion 232 is clamped with the second clamping groove 213. The purpose is to improve the stability of installation and disassembly and avoid wear or damage of components caused by hard connection.

[0071] Specifically, combined Figure 8 , Fig.11 As shown, a seal 27 is installed on the outer side of the female terminal block 23. After the plug 11 is inserted, the seal 27 is connected to the mounting hole 110 of the plug 11 to achieve a sealed connection. The purpose is to ensure the reliability and stability of the electrical connection.

[0072] Specifically, combined Figure 2 , Fig.13 , Fig.14 As shown, the terminal 13 is a telescopic terminal, the purpose of which is to improve the stability and reliability of the plug-in. For example, the terminal 13 is provided with a first shell 130 and a second shell 132, the first shell 130 is provided with a contraction portion 131 that contracts inward, and the second shell 132 is slidably installed in the first shell 130 and is limited by travel;

[0073] A spring 133 is disposed between the first shell 130 and the second shell 132 , one end of the spring 133 is connected to the second shell 132 , and the other end of the spring 133 is connected to the contraction portion 131 ;

[0074] The contraction portion 131 may be installed with a limiting member 134 . When the limiting member 134 is installed, one end of the spring 133 is connected to the second housing 132 , and the other end is connected to the limiting member 134 .

[0075] Among them, when the limit member 134 is not provided to support the spring 133, the lower end of the spring 133 can expand outward to form an expansion portion 133A, and the expansion portion 133A is against the contraction portion 131; and the terminal 13 can be fixed in the male terminal seat 12 by clamping and fixing it by relying on the contraction portion 131.

[0076] Combination Figure 1-Figure 4 , Figure 8-Figure 12As shown, when the present invention is in use: the female head housing 20 is first clamped with the rod sleeve 3, and then the rod body 10 is continuously inserted. During the insertion process, the plug 11 is attracted by the first magnet 24. As the plug 11 moves downward, the female head conductive member 26 will contact the terminal 13, and the female head terminal block 23 will also be pressed downward. During this period, the clamping clamp 28 is first opened, and then clamped and connected with the plug 11, so that the plug 11 and the female head terminal block 23 are clamped together;

[0077] Due to the travel limit of the anti-rotation groove 204, the second hook 281 of the clamping clamp 28 will not completely disengage from the expansion groove 202 and the slope 203, so that when the second hook 281 of the clamping clamp 28 is in the expansion groove 202, the plug 11 and the female terminal block 23 are clamped together (under the elastic force of the second elastic member 29, the second hook 281 moves toward the expansion groove 202, which makes the first hook 280 move toward the plug 11, achieving stable and reliable clamping), so that the plug 11 can move freely up and down within the travel range of the expansion groove 202 / the anti-rotation groove 204, and the connection with the female terminal block 23 is not released during this period;

[0078] When the plug 11 is pulled out, the second hook 281 of the clamping clamp 28 will move along the slope 203. At this time, the second elastic member 29 is compressed, and the first hook 280 is stretched open. The user then pulls hard, and the plug 11 is no longer clamped, and then the plug 11 can be pulled out. When the slope 203 is not provided, the user can also forcibly pull out the plug 11. Then the clamping clamp 28 is reset under the action of the second elastic member 29, and the female terminal block 23 is reset under the action of the first elastic member (spring) or magnetic force (repulsive magnetic force).

[0079] In summary, the blind plugging of component connection is realized through the above components and structures; after the terminal and the female conductive part are connected, the rod body (the rod body of the headrest / seat) can realize free movement in the axial direction (within the travel limit range), that is, the female terminal block moves with the plug, and the stability and reliability of the electrical connection are maintained during this period;

[0080] The above-mentioned clamping parts and other components form a clamping hook structure, which can prevent the device from breaking free after connection. At the same time, when the plug is pulled out, the clamping hook structure can be smoothly unlocked, and the structure is simple and practical.

[0081] Through the magnetic suspension structure and adsorption structure of magnets and other components, the adsorption structure further promotes the installation and connection of the plug and improves the connection reliability. The magnetic suspension structure is an optional structure, which increases the axial insertion range and avoids excessive pressing force during blind insertion, which may cause damage to the components. In conjunction with the external limiting structure, it also achieves travel locking of the axial range of activity. Compared with the optional spring-type floating structure, it has a larger travel adjustment range and less wear.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.
