Description

Technical Field

[0001] This utility model relates to the field of connecting wire technology, specifically a double-ended connecting wire for use inside automobiles. Background Technology

[0002] Double-ended connectors used inside automobiles generally refer to a type of cable typically used to connect different electrical components or devices. These connectors play a crucial role in the automotive electrical system, ensuring effective connections between various components. When selecting and installing them, factors such as safety, compatibility, and lifespan must be considered to guarantee the normal operation of the vehicle.

[0003] According to a public announcement (Publication No.: CN 214589562U), a high-temperature resistant connecting wire for automotive interiors includes a first protective shell and a second protective shell. The first and second protective shells are respectively provided with a first connector and a second connector inside, and the first and second protective shells are rotatably connected to the first connector and the second connector, respectively. The first protective shell is evenly provided with a first slot and a first sliding groove inside, and a first slider is slidably connected in the first sliding groove. The bottom end of the second protective shell is evenly fixed with a connecting block, and the connecting block engages with the first slot.

[0004] When double-ended connectors are used in cars, if the cable is too long, it may take up space inside the car, especially in small areas. The messy cable makes the interior layout more cluttered. Even with the cooperation of components such as the first and second protective shells, it is difficult to shorten the length of the double-ended cable, reduce the space occupied, make the interior layout neater, or prevent the double-ended cable from being worn or damaged by external objects. These issues need to be improved. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a double-ended connecting wire for use inside automobiles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-ended connecting cable for automotive interiors, comprising a double-ended cable, one end of which is fixedly connected to an interface, and a cable winding device provided at the bottom of the double-ended cable. The cable winding device includes a circular box, the bottom of which extends through the bottom of the double-ended cable. A circular rod is rotatably connected to the inner wall of the circular box, and a gear passes through the circumference of the circular rod. A slot is formed on the circumference of the circular box, and a rack is slidably connected to the inner wall of the slot. A second slot is formed on the circumference of the circular box, and a rack is slidably connected to the inner wall of the slot. A locking block is fixedly connected to the bottom of the rack. A locking block is also fixedly connected to the bottom of the rack. A long rod is fixedly connected to the top of the circular rod, and a rotating disk is fixedly connected to the end of the long rod away from the circular rod.

[0007] As described above, there are two card blocks, the double-headed line is located on the displacement trajectory of the card block, and a rectangular groove is formed on the circumferential surface of the circular box.

[0008] As described above, the rack and gear mesh with each other, one end of the double-headed wire passes through the inner wall of the rectangular groove, and the top of the round box is provided with a cover plate.

[0009] As described above, the inner wall of the circular box is provided with an anti-friction lubrication device, which includes a crossbar. One end of the crossbar is fixedly connected to the inner wall of the circular box, and the end of the crossbar away from the circular box is fixedly connected to a square frame. A turntable is rotatably connected to the inner wall of the square frame, and an extrusion block is fixedly connected to the circumference of the turntable. The end of the crossbar away from the inner wall of the circular box passes through the bottom of the turntable. An oil outlet pipe is fixedly connected to the inner wall of the square frame. A short pipe passes through one end of the oil outlet pipe, and a drain pipe passes through the side of the short pipe. An oil tank is fixedly connected to the top of the square frame, and the end of the drain pipe away from the short pipe passes through the side of the oil tank.

[0010] As mentioned above, one end of the oil outlet pipe is located at the top of the gear, and the oil outlet pipe is located on the displacement trajectory of the extrusion block.

[0011] As described above, there are several extrusion blocks arranged in a circumferential array on the circumferential surface of the turntable, and the oil outlet pipe is made of rubber.

[0012] As mentioned above, an oil inlet pipe runs through the side of the oil tank, and one end of the double-ended wire is fixedly connected to a socket.

[0013] Compared with existing technologies, this double-ended connecting wire for automotive interiors has the following advantages:

[0014] I. This utility model utilizes the interplay of components such as the circular box, circular rod, gear, and rack within the cable winding device to achieve a double-ended cable that rotates towards the inner wall of the circular rod, gradually winding the double-ended cable into a loop, thereby shortening its length. Through the rotating disc and related mechanical parts, the double-ended cable can be effectively retracted, reducing the space occupied. This is especially important in the confined space of a car interior, resulting in a neater interior layout. In the retracted state, the double-ended cable is less susceptible to wear or damage from external objects. When the double-ended cable is retracted, it avoids potential interference and noise during driving. The retracted double-ended cable does not scatter randomly inside the car, reducing the risk of tripping or obstructing driving and improving vehicle safety.

[0015] II. This utility model, through the cooperation of components such as the internal frame, rotating disk, extrusion block, and oil outlet pipe of the anti-friction lubrication device, achieves gear lubrication. Timely release of lubricating oil ensures that the gears maintain good lubrication during operation, thereby reducing friction and wear, extending the service life of the gears, ensuring the smooth operation of the double-ended cable, avoiding jamming or performance degradation caused by dry friction, ensuring the stability of electrical connections, reducing the need for regular manual inspection and maintenance, improving ease of use, and the flow of lubricating oil can effectively dissipate heat, preventing the double-ended cable and its connectors from being affected by excessive temperature, and avoiding electrical faults caused by heat.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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.

[0025] like Figure 1-6 As shown, this utility model provides a technical solution: a double-ended connecting cable for automotive interiors, including a double-ended cable 1, one end of which is fixedly connected to an interface 2, and a connecting cable winding device 3 at the bottom of the double-ended cable 1. The connecting cable winding device 3 includes a circular box 31, the bottom of which extends through the bottom of the double-ended cable 1. A circular rod 32 is rotatably connected to the inner wall of the circular box 31, and a gear 33 passes through the circumferential surface of the circular rod 32. A slot 34 is formed on the circumferential surface of the circular box 31, and a rack 35 is slidably connected to the inner wall of the slot 34. A second slot 36 is formed on the circumferential surface of the circular box 31, and a rack 37 is slidably connected to the inner wall of the slot 36. A locking block 38 is fixedly connected to the bottom of the rack 35, and a locking block 38 is fixedly connected to the bottom of the rack 37. A long rod 39 is fixedly connected to the top of the circular rod 32, and a rotating disk 310 is fixedly connected to the end of the long rod 39 away from the circular rod 32.

[0026] There are two card blocks 38. The double-headed line 1 is located on the displacement trajectory of the card block 38. A rectangular groove 311 is opened on the circumferential surface of the circular box 31.

[0027] The rack 35 and the gear 33 mesh with each other, one end of the double-headed wire 1 passes through the inner wall of the rectangular groove 311, and the top of the round box 31 is provided with a cover plate 6.

[0028] When a double-ended connector cable is used in a car, if the cable is too long, it may take up space inside the car, especially in areas with limited space. When it is necessary to shorten the cable, the double-ended cable 1 can be shortened and coiled up. Rotating the turntable 310 causes the long rod 39 to rotate, which in turn rotates the round rod 32. The round rod 32 then rotates the gear 33. Gear 33 meshes with rack 1 35 and rack 2 37. When gear 33 rotates, it causes rack 1 35 and rack 2 37 to slide on slot 1 34 and slot 2 36 respectively. When gear 33 rotates clockwise, it causes rack 1 35 and rack 2 37 to move relative to each other. This relative movement causes two locking blocks 38 to move relative to each other, locking the top of the double-ended cable 1. When the card block 38 moves relative to each other, it will drive the double-ended wire 1 to rotate. The round rod 32 is located in the middle of the double-ended wire 1. When the double-ended wire 1 rotates, it will rotate towards the inner wall of the round rod 32, slowly winding the double-ended wire 1 into a loop and rolling it into the inside of the round box 31, thereby shortening the exposed length of the double-ended wire 1. Through the rotating disk 310 and related mechanical components, the double-ended connecting wire can be effectively retracted, reducing the space occupied. This is especially important for the small interior environment of a car, making the interior layout more tidy. In the retracted state, the double-ended wire 1 is not easily worn or damaged by external objects. When the double-ended wire 1 is retracted, it avoids interference and noise that may be generated during driving. The retracted double-ended wire 1 will not be scattered randomly in the car, reducing the risk of tripping or obstructing driving during driving and improving vehicle safety.

[0029] As mentioned above, we also propose that an anti-friction lubrication device 4 is provided on the inner wall of the round box 31. The anti-friction lubrication device 4 includes a crossbar 312. One end of the crossbar 312 is fixedly connected to the inner wall of the round box 31. A square frame 41 is fixedly connected to the end of the crossbar 312 away from the round box 31. A turntable 42 is rotatably connected to the inner wall of the square frame 41. An extrusion block 43 is fixedly connected to the circumference of the turntable 42. The end of the crossbar 32 away from the inner wall of the round box 31 passes through the bottom of the turntable 42. An oil outlet pipe 44 is fixedly connected to the inner wall of the square frame 41. A short pipe 45 passes through one end of the oil outlet pipe 44. A drain pipe 46 passes through the side of the short pipe 45. An oil tank 47 is fixedly connected to the top of the square frame 41. The end of the drain pipe 46 away from the short pipe 45 passes through the side of the oil tank 47.

[0030] One end of the oil outlet pipe 44 is located at the top of the gear 33, and the oil outlet pipe 44 is located on the displacement trajectory of the extrusion block 43.

[0031] Several extrusion blocks 43 are arranged in a circumferential array on the circumferential surface of the turntable 42, and the oil outlet pipe 44 is made of rubber.

[0032] An oil inlet pipe 48 runs through the side of the oil tank 47, and one end of the double-ended wire 1 is fixedly connected to a socket 5.

[0033] As the aforementioned round rod 32 rotates, one end of the round rod 32, away from the inner wall of the round box 31, passes through the bottom of the turntable 42 and is fixedly connected to the turntable 42. However, it only passes through the square frame 41 without being fixedly connected. The square frame 41 is fixed to the inner wall of the round box 31 by the crossbar 312. Therefore, when the round rod 32 rotates, it will drive the turntable 42 to rotate. The rotation of the turntable 42 will drive several extrusion blocks 43 to rotate. The oil outlet pipe 44 is wrapped around the surface of the turntable 42 and is located on the movement trajectory of the extrusion blocks 43. When the extrusion blocks 43 rotate, they will intermittently extrude oil into the oil outlet pipe 44. The oil tank 47 flows lubricating oil into the oil outlet pipe 44 through the unblocking pipe 46. When the oil outlet pipe 44 is intermittently extruded by the extrusion blocks 43, it will extrude lubricating oil into the oil outlet pipe 44. The lubricating oil flows out slowly, with one end of the oil outlet pipe 44 located on the gear 33. The flowing lubricating oil flows onto the gear 33, and oil flows out once every time the gear 33 rotates, lubricating the gear 33. The timed release of lubricating oil can ensure that the gear 33 always maintains a good lubrication state during operation, thereby reducing friction and wear, and extending the service life of the gear 33. The lubricating oil can ensure the smooth movement of the double-ended wire 1, avoid jamming or performance degradation caused by dry friction, ensure the stability of electrical connection, reduce the need for manual periodic inspection and maintenance, and improve the convenience of use. The flow of lubricating oil can effectively dissipate heat, prevent the double-ended wire 1 and its connector from being affected by excessive temperature, and avoid electrical failures caused by heat.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
