Description

Technical Field

[0001] This utility model relates to the technical field of wiring harness fixing devices, and more specifically, to a wiring harness fixing device for a child safety seat. Background Technology

[0002] In the field of child safety seats, ensuring children's safety while traveling in a car is of paramount importance, and the stable securing of the wiring harness is an indispensable part of this. With the continuous development of automotive safety technology, more and more child safety seats are equipped with electronic components. These electronic components are connected to external electrical devices through wiring harnesses to achieve more functions, such as intelligent monitoring, ventilation, and heating, providing children with a more comfortable and safer riding experience.

[0003] In some technologies, when the wiring harness is not effectively secured, vibrations generated during vehicle movement can affect the wiring harness connecting the child safety seat and vehicle equipment. This can cause the harness to retract or pull out. When the harness retracts, the length extending beyond the child safety seat is shorter, easily leading to loosening or even detachment of the connector at one end, thus affecting the normal functioning of the child safety seat. Therefore, inventing a wiring harness securing device for child safety seats to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a wiring harness fixing device for a child safety seat. It aims to solve the problem that when the wiring harness is not effectively fixed, the vibration generated during vehicle movement will act on the wiring harness connecting the safety seat and the vehicle equipment. At this time, the wiring harness is prone to retraction or pull-out. When the wiring harness retracts, the length of the wiring harness extending outside the child safety seat is short, which can easily cause the connector at one end of the wiring harness to loosen or even fall off, thereby affecting the normal use of the safety seat.

[0005] This utility model is implemented as follows: This utility model provides a wiring harness fixing device for a child safety seat, including a fixing box and a sealing plate disposed on the fixing box. The inner wall of the fixing box is respectively equipped with a first fixing frame, a fixing block and an adjusting block. A sliding rod is installed at one end of the fixing block, a first guide frame is installed at the upper end of the fixing block, and a first clamping frame is installed at the upper end of the adjusting block. The lower end of the sealing plate is respectively equipped with a second fixing frame and a second guide frame, and the sealing plate and the fixing box are fixed together by bolts.

[0006] Preferably, the two sets of fixing blocks and adjusting blocks are symmetrically arranged on both sides of the fixing box. The side walls of the first fixing frame and fixing blocks are fixedly connected to the inner wall of the fixing box. One end of the adjusting block is provided with an installation groove, and a spring is installed on the inner wall of the installation groove.

[0007] Preferably, the two end sidewalls of the spring are fixedly connected to the mounting groove and the inner wall of the fixing box, respectively, the inner wall of the mounting groove and the outer wall of the slide rod are slidably connected, and the first clamping frame is an elastic clamp to clamp and fix the wire harness.

[0008] Preferably, two second guide frames are symmetrically installed on one side of the outer wall of the sealing plate, the first fixing frame and the second fixing frame cooperate to clamp and fix the wire harness, and the first guide frame and the second guide frame cooperate to limit the sliding of the wire harness.

[0009] Preferably, the fixed box has symmetrical sliding plates installed inside, and a rotating shaft is rotatably connected between the two sliding plates. The outer wall of the rotating shaft is slidably connected to the outer wall of the wire harness.

[0010] Preferably, the fixing box has symmetrical limiting grooves on the outer walls of both sides near the slide plate, and a limiting block is fixedly connected to one side of the slide plate. The outer wall of the limiting block and the inner wall of the limiting groove are slidably connected.

[0011] The beneficial effects of this utility model are: The securing device divides the wiring harness into two parts. When the child safety seat is vibrated during vehicle movement, the force is applied only to the wiring harness on one side of the securing box, causing the force generated by the vibration to pull the wiring harness on that side outwards. This prevents the other end of the wiring harness from being affected and detached from the device. After the vibration ends, the wiring harness returns to its initial position, preventing too many wires from detaching from the securing box and affecting the overall appearance. This device not only secures the wiring harness but also effectively prevents the child safety seat device interface wiring harness from falling off due to vibrations generated by vehicle movement, ensuring the normal use of the child safety seat function.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example, refer to Figures 1-6 A wiring harness fixing device for a child safety seat includes a fixing box 1 and a sealing plate 3 disposed on the fixing box 1. The inner wall of the fixing box 1 is respectively equipped with a first fixing frame 11, a fixing block 12 and an adjusting block 13. A slide rod 121 is installed at one end of the fixing block 12, a first guide frame 122 is installed at the upper end of the fixing block 12, and a first clamping frame 131 is installed at the upper end of the adjusting block 13. The lower end of the sealing plate 3 is respectively equipped with a second fixing frame 31 and a second guide frame 32, and the sealing plate 3 and the fixing box 1 are fixed together by bolts.

[0017] Furthermore, two sets of fixing blocks 12 and adjusting blocks 13 are symmetrically arranged on both sides of the fixing box 1. The side walls of the first fixing frame 11 and fixing blocks 12 are fixedly connected to the inner wall of the fixing box 1. One end of the adjusting block 13 is provided with an installation groove 132. A spring 14 is installed on the inner wall of the installation groove 132. The two side walls of the spring 14 are fixedly connected to the installation groove 132 and one side inner wall of the fixing box 1, respectively. The inner wall of the installation groove 132 is slidably connected to the outer wall of the slide rod 121. The first clamping frame 131 is an elastic clamp to clamp and fix the wire harness. Two second guide frames 32 are symmetrically installed on one side outer wall of the sealing plate 3. The first fixing frame 11 and the second fixing frame 31 cooperate to clamp and fix the wire harness. The first guide frame 122 and the second guide frame 32 cooperate to limit the sliding of the wire harness.

[0018] It should be noted that before use, the two ends of the wire harness should be squeezed together to clamp and fix it into the inner wall of the first clamping frame 131. At the same time, the middle section of the wire harness located in the middle should be placed on the first fixing frame 11, and the two ends near the first clamping frame 131 should be placed on the first guide frame 122. A bent wire harness of the same length should be reserved between the first guide frame 122 and the first fixing frame 11. Then, the sealing plate 3 is installed on the upper end of the fixing box 1 with bolts. The second fixing frame 31 is used in conjunction with the first fixing frame 11 to clamp and fix the wire harness. At the same time, the first guide frame 122 and the second guide frame 32 restrict the sliding direction of the wire harness to prevent it from deviating. The two ends of the wiring harness slide through the fixing box 1 and connect to the devices at both ends. When the safety seat vibrates during the car's operation, in order to avoid pulling the wiring harness and causing the device interface to detach, the position of the wiring harness in the fixing frame remains unchanged, and only one side of the wiring harness slides. The first fixing frame 11 drives the wiring harness on that side to pull outward toward the fixing box 1. During the pulling process, the adjusting block 13 squeezes the spring 14 and moves, and the internally bent wiring harness stretches out, thereby avoiding damage to the wiring harness caused by taut pulling. In this way, the vibration can be converted into the energy of the wiring harness moving outward on one side, thereby improving the overall service life of the wiring harness. After vibration ends, the adjusting block 13 drives the first clamping frame 131 and the upper wire harness to retract into the fixing box 1 under the restoring force of the spring 14. At the same time, the fixing block 12 limits the adjusting block 13 to prevent excessive rebound pulling on the wire harness and to prevent the opposite vibration force from pulling the wire harness and causing it to fall off. The fixing frame divides the wire harness into two parts. When subjected to vibration, according to the direction of the force, it only acts on the wire harness on one side of the fixing box 1, so that the force generated by the vibration drives the wire harness on that side to be pulled outward, avoiding affecting the other end of the wire harness and causing it to detach from the device. After vibration ends, the wire harness returns to its initial position, preventing too many wire harnesses from falling off the fixing box 1 and affecting the overall appearance. This device not only fixes the wire harness, but also effectively prevents the vibration generated by vehicle movement from causing the child safety seat device interface wire harness to fall off, ensuring the normal use of the safety seat function.

[0019] Furthermore, symmetrical sliding plates 2 are installed inside the fixing box 1. A rotating shaft 22 is rotatably connected between the two sliding plates 2. The outer wall of the rotating shaft 22 is slidably connected to the outer wall of the wire harness. Symmetrical limiting grooves 15 are opened on the outer walls of the fixing box 1 near the two sides of the sliding plates 2. A limiting block 21 is fixedly connected to one side of the sliding plate 2. The outer wall of the limiting block 21 is slidably connected to the inner wall of the limiting groove 15.

[0020] It should be noted that during the process of pulling and restoring the bent wire harness, in order to ensure that it can return to its initial bent shape, under normal conditions, with the help of the pivot 22 and the sliding plates 2 at both ends, gravity is used to press the bent wire harness downward, so that the wire harness achieves a regular bend. When the wire harness is pulled out, the pulling force will push the pivot 22 and the sliding plates 2, causing them to slide upward under the action of the limiting block 21 and the limiting groove 15 to accommodate the pulling out of the wire harness. After the wire harness pulling action is completed, under the action of the pivot 22 and the sliding plates 2, the wire harness is pushed downward again to restore it to its initial bent state, thereby avoiding damage to the wire harness caused by disordered bending and thus improving the service life of the wire harness.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
