Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to an automobile roof wiring harness fixing device. Background Technology

[0002] With the rapid development of passenger vehicles, many electrical components, such as interior lights, have been added to the headliner of automobiles. These components need to be connected to electrical junction boxes using cable harnesses to be powered, which has led to an increase in the number of cable harnesses that need to be installed and fixed on the headliner. The cable harnesses need to be fixed according to the preset route for easy maintenance. Currently, the cable harnesses need to be manually installed and attached to the headliner by production operators according to the preset route, resulting in significant differences in the appearance of each product's cable harness installation and deviation from the preset route.

[0003] CN220628769U discloses a wiring harness fixing device for an automotive roof. This device includes a mounting plate, limiting members, and an adhesive layer. The limiting members are arranged in pairs on the mounting plate, with multiple pairs spaced apart along a preset wiring harness fixing route. The wiring harness can be mounted between the pairs of limiting members. The adhesive layer is disposed between the pairs of limiting members. The limiting members can pre-position the wiring harness, allowing it to be mounted on the mounting plate along the preset wiring harness fixing route. Furthermore, before the adhesive layer hardens, manual positioning is not required, improving installation efficiency. However, this patent still has the following problems in practical use:

[0004] In the aforementioned device, the distance between the two limiting pins gradually increases from the end closer to the mounting plate to the end farther away from the mounting plate, thus satisfying the constraint on wire harnesses of different sizes. However, this method inevitably results in a certain segment of the wire harness that cannot be inserted between the two limiting pins, and another segment of the wire harness that cannot be locked by the limiting pins. Ultimately, this leads to two segments of wire in a whole wire harness that cannot be effectively fixed, resulting in poor wire harness fixing effect.

[0005] A car roof wiring harness fixing device is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a car roof wiring harness fixing device to solve the problem in the aforementioned device in the background art, where the distance between the two limiting pins gradually increases from the end closer to the mounting plate to the end farther away from the mounting plate to meet the constraint of wiring harnesses of different sizes. However, this method inevitably results in a certain section of the wiring harness that cannot be inserted between the two limiting pins, and another section of the wiring harness that cannot be locked by the limiting pins. Ultimately, this leads to the problem that there are always two sections of wire in a whole wiring harness that cannot be effectively fixed, resulting in poor wiring harness fixing effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a car roof wiring harness fixing device, comprising a roof with a wire clamping assembly installed, and a mounting plate installed on the bottom surface of the roof;

[0008] The wire clamping assembly is located on the bottom surface of the mounting plate. The wire clamping assembly includes a fixing compartment, which is fixedly connected to the bottom surface of the mounting plate. Side plates are symmetrically fixed to the top of the fixing compartment, and a connecting rod is fixedly connected between the two side plates. Rotary clamps are symmetrically rotatably mounted on the outside of the connecting rod.

[0009] The fixed compartment is symmetrically and slidably connected to movable trays on both sides, and several spring rods are rotatably installed between the movable trays and the outer side of the rotating clamp.

[0010] The mounting plate has mounting mechanisms symmetrically arranged on both sides.

[0011] Preferably, a control plate is fixedly installed at one end of the movable pallet inside the fixed compartment. The surface of the control plate is provided with an adjustment groove, which is an annular groove, and a connecting column is slidably connected inside the adjustment groove.

[0012] Preferably, one end of the other movable pallet is fixedly installed with an extension plate inside the fixed compartment. The top surface of the extension plate is rotatably connected to a rotating folding rod, the other end of which is fixedly connected to a connecting column. A first spring is fixedly installed between the extension plate and the control plate.

[0013] Preferably, a lever is fixedly connected to the top outer side of the rotating clamp.

[0014] Preferably, the installation mechanism includes a connecting block fixed to the side of the fixed compartment, a through groove is provided in the middle of the connecting block, a positioning block is connected through the inside of the through groove, the positioning block is fixedly installed on the surface of the mounting plate, and through holes are symmetrically provided on both sides of the top of the positioning block.

[0015] Preferably, a limiting ring is sleeved on the outside of the positioning block, a locking pin is connected through the inside of the through hole, and one end of the locking pin passes through the limiting ring and is fixedly connected to a pull ring.

[0016] Preferably, the pull rings are distributed on different sides of the limiting ring, and a third spring is fixedly installed between the limiting ring and the positioning block, the third spring being sleeved outside the locking pin.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This automotive roof wiring harness fixing device allows the rotating clamps on both sides to hold the wiring harness, and further tightens it under the push of the spring rod. This allows the device to not only hold wiring harnesses of various sizes, but also ensures that no section of the wiring harness will hang freely and sway, thus increasing the fixing effect of the wiring harness. The specific details are as follows:

[0018] 1. By inserting the wire harness between two rotating clamps and then pushing the two movable trays, the distance between the extension plate and the control plate is brought closer, causing the connecting post to move in the adjustment groove and drive the rotating lever to rotate. The first spring pushes the two movable trays to separate from each other, and the connecting post can engage with the two sides of the adjustment groove. Finally, the spring rods on both sides move and retract, pushing the rotating clamps to further clamp the wire harness. This device can not only clamp wire harnesses of various sizes, but also ensure that the wire harness does not hang freely and sway, thus increasing the fixing effect of the wire harness.

[0019] 2. By aligning the fixing compartment connecting blocks on both sides of the mounting plate with the positioning block, then using the thumb and middle finger to open the pull ring and put the limiting ring on the outside of the positioning block, and then releasing the pull ring to allow the third spring to pull the locking pin to move and pass through the through hole; finally, the fixing compartment can be quickly separated from the mounting plate, which is convenient for the disassembly and maintenance of the fixing compartment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides a technical solution: a car roof wiring harness fixing device, including a roof 1 with a wire clamping assembly 2 installed, and a mounting plate 101 installed on the bottom surface of the roof 1; the mounting plate 101 is bonded to the roof 1 with adhesive.

[0028] The wire clamping assembly 2 is located on the bottom surface of the mounting plate 101. The wire clamping assembly 2 includes a fixing compartment 201, which is fixedly connected to the bottom surface of the mounting plate 101. Side plates 202 are symmetrically fixed on the top of the fixing compartment 201. A connecting rod 203 is fixedly connected between the two side plates 202. A rotating clamp 204 is symmetrically rotatably mounted on the outside of the connecting rod 203.

[0029] Among them, the fixed compartment 201 is symmetrically slidably connected to the two sides of the movable tray 205, and several spring rods 206 are rotatably installed between the movable tray 205 and the outer side of the rotating clamp 204; the spring rods 206 have strong elasticity and are not easy to retract under the vibration of the vehicle.

[0030] The mounting plate 101 has mounting mechanisms 3 symmetrically arranged on both sides.

[0031] A control plate 207 is fixedly installed at one end of a movable pallet 205 located inside the fixed compartment 201. An adjustment groove 212 is provided on the surface of the control plate 207. The adjustment groove 212 is an annular groove. A connecting column 210 is slidably connected inside the adjustment groove 212. The connecting column 210 can only slide unidirectionally within the adjustment groove 212. Special bends are provided on both the left and right sides of the adjustment groove 212.

[0032] Another movable pallet 205 is located inside the fixed compartment 201, with an extension plate 208 fixedly installed at one end. The top surface of the extension plate 208 is rotatably connected to a rotating folding rod 209. The other end of the rotating folding rod 209 is fixedly connected to a connecting column 210. A first spring 211 is fixedly installed between the extension plate 208 and the control plate 207. When the connecting column 210 slides in the adjustment groove 212, the rotating folding rod 209 rotates, and the first spring 211 pushes the two extension plates 208 and the control plate 207 to separate from each other, thereby facilitating the engagement of the connecting column 210 with the two sides of the adjustment groove 212.

[0033] A lever 213 is fixedly connected to the top outer side of the rotating clip 204; the lever 213 facilitates opening the two rotating clips 204 in the initial state and then placing the wire harness between the two rotating clips 204.

[0034] The installation mechanism 3 includes a connecting block 301 fixed to the side of the fixed compartment 201. A through groove is provided in the middle of the connecting block 301, and a positioning block 302 is connected through the inside of the through groove. The positioning block 302 is fixedly installed on the surface of the mounting plate 101, and through holes are symmetrically provided on both sides of the top of the positioning block 302.

[0035] A limiting ring 303 is sleeved on the outside of the positioning block 302. A locking pin 304 is connected through the through hole. One end of the locking pin 304 passes through the limiting ring 303 and is fixedly connected to a pull ring 305. The ring opening of the pull ring 305 is easy for the worker's fingers to pass through, so that the limiting ring 303 can be disassembled with one hand. The limiting ring 303 fits against the outside of the positioning block 302.

[0036] Pull rings 305 are distributed on different sides of the limiting ring 303. A third spring 306 is fixedly installed between the limiting ring 303 and the positioning block 302. The third spring 306 is sleeved on the outside of the locking pin 304. The third spring 306 has low elasticity and can pull the locking pin 304 through the limiting ring 303 and the positioning block 302, so that the limiting ring 303 prevents the fixing chamber 201 from falling off.

[0037] Working principle: Before using this type of automotive roof wiring harness fixing device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, the wire harness is first inserted between two rotating clamps 204, causing two spring rods 206 to push the rotating clamps 204 to clamp the wire harness. Then, two movable support plates 205 are pushed, bringing the distance between the extension plate 208 and the control plate 207 closer. Next, the connecting post 210 moves in the adjustment groove 212, causing the rotating folding rod 209 to rotate. At this time, the first spring 211 pushes the two movable support plates 205 to separate from each other, and the connecting post 210 can engage with both sides of the adjustment groove 212. Finally, while the spring rods 206 on both sides move and retract, they push the rotating clamps 204 to further clamp the wire harness. This device can not only clamp wire harnesses of various sizes, but also ensure that the wire harness does not hang freely and sway, increasing the fixing effect of the wire harness.

[0038] By connecting the fixing compartments 201 connecting blocks 301 on both sides of the mounting plate 101 with the positioning blocks 302, then using the thumb and middle finger to open the pull ring 305, and then putting the limiting ring 303 on the outside of the positioning block 302, and then releasing the pull ring 305 to allow the third spring 306 to pull the locking pin 304 to move and pass through the through hole; finally, the fixing compartment 201 can be quickly separated from the mounting plate 101, which facilitates the disassembly and maintenance of the fixing compartment 201.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
