[0001] The utility model relates to the technical field of automotive wire harness protection, and specifically relates to an automotive wire harness protection sleeve with noise reduction and wear resistance. Background Technique
[0002] The automotive wire harness is the network main body of the automotive circuit. Without the wire harness, there would be no automotive circuit. A wire harness refers to a component formed by crimping contact terminals made of copper material to electrical wires and cables, and then plastically pressing an insulator outside or adding a metal shell, etc., and bundling the wire harness to form a component for connecting the circuit. The wire harness industrial chain includes electrical wires and cables, connectors, processing equipment, wire harness manufacturing, and downstream application industries. The wire harness is widely used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wire harness connects the entire vehicle body.
[0003] During the driving of the vehicle, the automotive wire harness will shake inside the vehicle, resulting in friction between the wire harnesses. Over time, the automotive wire harness will be damaged, affecting the normal use of the vehicle. Therefore, it is necessary to install a protection sleeve outside the automotive wire harness to avoid damage caused by friction of the automotive wire harness.
[0004] The existing automotive wire harness protection sleeve can only protect the automotive wire harness during use. However, installing the protection sleeve outside the automotive wire harness will increase the mass of the automotive wire harness, resulting in the wire harness and the protection sleeve colliding inside the vehicle during driving, causing abnormal noises and affecting safe driving.
[0005] Therefore, a noise-reducing and wear-resistant automotive wire harness protection sleeve is proposed. Content of the Utility Model
[0006] The purpose of the utility model is to provide a noise-reducing and wear-resistant automotive wire harness protection sleeve to solve the problems raised in the above background technique. To achieve the above purpose, the utility model provides the following technical solution: a noise-reducing and wear-resistant automotive wire harness protection sleeve, including a protection sleeve main body. A connecting band is installed on one side of the protection sleeve main body. A first binding band and a second binding band are installed on one side of the connecting band. A plurality of limiting rack teeth are equidistantly installed on one side of the first binding band. A limiting ring is installed on one side of the second binding band. A torsion spring is installed on each of the two sides inside the limiting ring. A transmission rod is installed between the two torsion springs. A limiting plate is installed at the bottom of the transmission rod. A control block is installed on one side of the limiting ring.
[0007] Preferably, the limiting rack teeth are in the shape of helical teeth, and the limiting rack teeth are used in cooperation with the limiting plate.
[0008] Preferably, the output end of the control block extends into the inside of the limiting ring, and the output end of the control block is connected to one end of the transmission rod.
[0009] Preferably, both sides of the limiting ring are in an open state, and the first strap is used in cooperation with the limiting ring.
[0010] Preferably, a sound-absorbing cotton is provided inside the main body of the protective sleeve, and an outer wear-resistant layer and an inner wear-resistant layer are respectively provided on both sides of the sound-absorbing cotton.
[0011] Preferably, a plurality of rubber anti-slip pads are equidistantly installed on the outer side of the inner wear-resistant layer.
[0012] Preferably, a round felt and a barbed felt are installed on the outer side of the outer wear-resistant layer, and the round felt and the barbed felt are used in cooperation.
[0013] Preferably, a fixing block is installed on the outer side of the outer wear-resistant layer, and a fixing ring is hinged inside the fixing block. The fixing ring is provided with a first limiting hole and a second limiting hole, and the fixing ring is used in cooperation with the main body of the protective sleeve.
[0014] Compared with the prior art, the utility model provides a noise-reducing and wear-resistant protective sleeve for automotive wiring harnesses, which has the following beneficial effects:
[0015] By providing a main body of the protective sleeve, a first strap, a limiting rack, a limiting ring and a limiting plate, after the automotive wiring harness is protected by the main body of the protective sleeve, the main body of the protective sleeve together with the protected automotive wiring harness is fixed to a certain support structure in the vehicle through the first strap and the second strap. One end of the first strap is inserted into the limiting ring and extends out. When the first strap is inserted into the limiting ring, the limiting plate will swing along the opening direction of the limiting rack. Through the acting force of the torsion spring, the limiting plate can form a limiting connection with the limiting rack, thereby avoiding the situation that the first strap actively falls out of the limiting ring, ensuring the stability of the connection with the vehicle body structure. Through this protective sleeve, it is possible to prevent the protected line from colliding with the vehicle body structure in the vehicle and causing abnormal noises, improving driving safety.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Embodiment 1: A connecting strap 8 is installed on one side of the protective cover body 1. A first strap 7 and a second strap 9 are installed on one side of the connecting strap 8. A plurality of limit racks 6 are equidistantly installed on one side of the first strap 7. A limit ring 10 is installed on one side of the second strap 9. A torsion spring 13 is installed on each of the two sides inside the limit ring 10. A transmission rod 12 is installed between the two torsion springs 13. A limit plate 11 is installed at the bottom of the transmission rod 12. A control block 14 is installed on one side of the limit ring 10. The limit rack 6 is in a helical tooth shape and is used in cooperation with the limit plate 11. The output end of the control block 14 extends into the inside of the limit ring 10, and the output end of the control block 14 is connected to one end of the transmission rod 12.
[0023] Specifically, as Figure 1 and Figure 2As shown, since one side of the protective cover body 1 is connected with a first strap 7 and a second strap 9 through a connecting strap 8, after the automotive wire harness is protected by the protective cover body 1, the protective cover body 1 together with the protected automotive wire harness can be fixed at a certain support structure inside the vehicle through the first strap 7 and the second strap 9. Since a limiting ring 10 is installed on one side of the second strap 9, one end of the first strap 7 is inserted into the limiting ring 10 and extends out. Since a plurality of limiting racks 6 are equidistantly installed on one side of the first strap 7, and a limiting plate 11 is movably installed inside the limiting ring 10, when the first strap 7 is inserted into the limiting ring 10, the limiting plate 11 will swing along the opening direction of the limiting rack 6. Since both ends of the transmission rod 12 are respectively connected with a torsion spring 13, the acting force of the torsion spring 13 can make the limiting plate 11 form a limiting connection with the limiting rack 6, thus avoiding the situation that the first strap 7 actively falls out of the limiting ring 10, ensuring the stability of the connection with the vehicle body structure. When it is necessary to separate the first strap 7 and the second strap 9, the control block 14 is triggered to drive the transmission rod 12 to rotate, so that the limiting plate 11 is separated from the limiting rack 6, and then the first strap 7 can be pulled out from the limiting ring 10. Through this protective cover, it is possible to avoid the situation that the protected wire collides with the vehicle body structure inside the vehicle and causes abnormal noise, improving driving safety.
[0024] Embodiment 2: Both sides of the limiting ring 10 are in an open state, and the first strap 7 is used in cooperation with the limiting ring 10. Sound-absorbing cotton 18 is provided inside the protective cover body 1, and an outer wear-resistant layer 17 and an inner wear-resistant layer 19 are respectively provided on both sides of the sound-absorbing cotton 18. A plurality of rubber anti-slip pads 20 are equidistantly installed on the outer side of the inner wear-resistant layer 19. A round felt 2 and a barbed felt 3 are installed on the outer side of the outer wear-resistant layer 17, and the round felt 2 and the barbed felt 3 are used in cooperation. A fixing block 5 is installed on the outer side of the outer wear-resistant layer 17, and a fixing ring 4 is hinged inside the fixing block 5. A first limiting hole 15 and a second limiting hole 16 are provided inside the fixing ring 4, and the fixing ring 4 is used in cooperation with the protective cover body 1.
[0025] Specifically, as Figure 1 、 Figure 3 and Figure 4As shown, since the interior of the protective sleeve body 1 is provided with a sound-absorbing cotton 18, the sound-absorbing cotton 18 can absorb sound, thereby further reducing the abnormal noise generated during the use of the automotive wiring harness. Since the outer wear-resistant layer 17 and the inner wear-resistant layer 19 are respectively provided on both sides of the sound-absorbing cotton 18, the overall wear-resistant strength of the protective sleeve body 1 can be improved through the outer wear-resistant layer 17 and the inner wear-resistant layer 19, and the service life of the protective sleeve body 1 can be increased. Since a plurality of rubber anti-slip pads 20 are equidistantly installed on one side of the inner wear-resistant layer 19, the friction between the inner wear-resistant layer 19 and the wire harness to be protected can be increased through the rubber anti-slip pads 20, thereby improving the protection effect on the automotive wiring harness. When protecting the automotive wiring harness, the entire automotive wiring harness can be wrapped inside the protective sleeve body 1. Subsequently, one end of the protective sleeve body 1 is inserted into the first limiting hole 15 and then extends out from the second limiting hole 16. By connecting the prickly felt 3 with the round felt 2, the entire protective sleeve body 1 can be completely wrapped outside the automotive wiring harness, thereby protecting the automotive wiring harness and preventing the automotive wiring harness from being damaged.
[0026] Working principle: When in use, first wrap the automotive wiring harness inside the protective sleeve body 1. Subsequently, one end of the protective sleeve body 1 is inserted into the first limiting hole 15 and then extends out from the second limiting hole 16. By connecting the prickly felt 3 with the round felt 2, the entire protective sleeve body 1 can be completely wrapped outside the automotive wiring harness, thereby protecting the automotive wiring harness and preventing the automotive wiring harness from being damaged. After protecting the automotive wiring harness through the protective sleeve body 1, the protective sleeve body 1 together with the protected automotive wiring harness can be fixed at a certain support structure inside the vehicle through the first strap 7 and the second strap 9, preventing the protected wiring from colliding with the vehicle body structure inside the vehicle and causing abnormal noise, and improving driving safety.
