Description

Technical Field

[0001] This utility model relates to the field of throttle cable technology, specifically to an automotive throttle cable mechanism. Background Technology

[0002] The throttle cable mechanism is a key component in traditional internal combustion engine vehicles that connects the accelerator pedal to the engine throttle valve. It plays a crucial role in the process by which the driver controls the vehicle speed by pressing the accelerator pedal. This mechanism allows the driver to precisely adjust the amount of air entering the engine, thereby controlling the engine's power output and vehicle speed.

[0003] The patent with publication number CN212400907U discloses a throttle cable assembly for automobiles, including a cable sleeve. A cable body is slidably connected inside the cable sleeve. A guide structure is provided on the outside of the cable sleeve. The guide structure includes a guide tube, a threaded groove, a mounting slider, an abutment block, and an elastic pad. The threaded groove is formed on the side of the guide tube. The mounting slider is slidably connected to the guide tube through the threaded groove. The abutment block is slidably connected to one end of the mounting slider located inside the guide tube. The elastic pad is fixedly connected to the end of the abutment block opposite to the mounting slider. The side of the elastic pad has an arc-shaped structure. A protective structure is provided in the middle of the guide tube.

[0004] However, the aforementioned device presents the following problems during use: In actual operation, the larger diameter connectors (which are not deformable) at both ends of the cable pose specific challenges during the cable threading process. Specifically, during installation, to allow the cable to pass smoothly through the guide structure (guide tube), one side of the connector usually needs to be disassembled first, allowing the cable to smoothly enter and move along the preset path. After threading, the connector must be reinstalled to ensure the normal operation of the entire system. This process not only increases the complexity of the installation steps but also inevitably prolongs the assembly time and reduces overall work efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automobile throttle cable mechanism that simplifies the installation process and is easy to use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A car throttle cable mechanism includes a cable body and a fixing plate. Mounting plates are fixedly installed on both sides of the fixing plate. Fixed semicircular rings are fixedly installed on both mounting plates. Fixed semicircular ring protective tubes are fixedly installed on the fixed semicircular rings. Movable semicircular rings are slidably installed on both mounting plates.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 6 A car throttle cable mechanism includes a cable body 1 and a fixing plate 4. Mounting plates 5 are fixedly installed on both sides of the fixing plate 4. Fixed semi-circular rings 6 are fixedly installed on both mounting plates 5. Fixed semi-circular ring protection tubes 7 are fixedly installed on the fixed semi-circular rings 6. Movable semi-circular rings 8 are slidably installed on both mounting plates 5. Movable semi-circular ring protection tubes 9 are fixedly installed between the two movable semi-circular rings 8. A drive assembly is provided inside the mounting plate 5.

[0019] By moving the two movable semicircular rings 8 synchronously, the movable semicircular protective pipe 9 can be moved synchronously, thereby changing the distance between the movable semicircular protective pipe 9 and the fixed semicircular protective pipe 7. Thus, without disassembly, the corresponding part of the cable body 1 can be directly placed into the space formed by the movable semicircular protective pipe 9 and the fixed semicircular protective pipe 7 through the gap between the movable semicircular protective pipe 9 and the fixed semicircular protective pipe 7, completing the initial placement activity.

[0020] Once the placement is complete, simply move the two movable semicircular rings 8 in opposite directions simultaneously, causing the movable semicircular protective pipe 9 to gradually approach the fixed semicircular protective pipe 7. The cable body 1 is then encased in the protective structure composed of the fixed semicircular protective pipe 7 and the movable semicircular protective pipe 9, and can be placed according to the predetermined bending degree. This avoids unnecessary bending during use and ensures the service life of the cable body 1.

[0021] Connectors 3 are installed on both sides of the cable body 1. The cable body 1 is surrounded by a cable sleeve 2. The connector 3 is designed to facilitate quick connection with other components, while the cable sleeve 2 can effectively protect the cable from external damage and improve overall reliability.

[0022] The drive assembly includes two threaded rods 15, both of which are rotatably mounted inside the corresponding mounting plate 5. A synchronous chain 17 is installed between the two threaded rods 15 via a sprocket. Nut pairs 16 are threadedly mounted on both threaded rods 15, and the nut pairs 16 are fixedly connected to the corresponding movable semi-circular rings 8.

[0023] When one of the threaded rods 15 rotates, the two threaded rods 15 can rotate synchronously through the transmission action of the synchronous chain 17, which in turn causes the two nut pairs 16 to rotate synchronously, causing the two movable semicircular rings 8 to rotate synchronously, thus enabling the movable semicircular rings to move the protective pipe 9.

[0024] Preferably, chain drive or gear drive should be used between the sprocket and the synchronous chain 17 to ensure the transmission ratio and avoid slippage.

[0025] One of the threaded rods 15 has a connecting rod 10 fixedly installed at one end away from the fixed plate 4. The connecting rod 10 passes through the corresponding mounting plate 5 and has an operating block 11 fixedly installed thereon.

[0026] The operator can rotate the threaded rod 15 by rotating the operating block 11, thereby adjusting the position of the movable semi-ring protection pipe 9.

[0027] A sealing lip 12 is fixedly installed on the outer side of the fixed semi-circular ring 6 and the outer side of the movable semi-circular protective pipe 9. A sealing gasket 18 is embedded on the surfaces of the two sealing lips 12 facing each other.

[0028] The distance between the two closed lips 12 is the "insertion gap" through which the cable body 1 enters, allowing the cable body 1 to smoothly enter the guide structure.

[0029] When the product is in place, the two sealing gaskets 18 fit tightly together to prevent dust from entering the interior through the gaps and affecting its service life.

[0030] Both the inner side of the fixed semicircular ring 6 and the inner side of the movable semicircular ring protective pipe 9 are fixedly installed with shielding lips 13. The shielding lips 13 on the fixed semicircular ring 6 and the shielding lips 13 on the movable semicircular ring protective pipe 9 are installed in a staggered manner, and the length of the shielding lips 13 is greater than the length of the closing lips 12.

[0031] When the distance between the two closed lips 12 is sufficient for the cable body 1 to be inserted, the gap between the two blocking lips 13 will be smaller than the insertion gap. Thus, the blocking lips 13 can block the inserted cable body 1, preventing the cable body 1 from slipping through the gap on the other side, and facilitating quick placement.

[0032] The timing chain 17 is located inside the fixed plate 4, which helps protect the timing chain 17 from external factors and reduces noise and wear.

[0033] Both mounting plates 5 have grooves 14 at corresponding positions for the corresponding movable semi-ring protection pipe 9 to slide. The presence of the grooves 14 ensures that the movable semi-ring protection pipe 9 can move smoothly along the preset path, achieving precise position adjustment.

[0034] The working process of this utility model is as follows: First, the two movable semicircular rings 8 are moved outward synchronously by the driving component, increasing the distance between the movable semicircular protective pipe 9 and the fixed semicircular protective pipe 7. This creates a sufficient "insertion gap" that allows the cable body 1 to pass directly through this gap into the space formed by the fixed semicircular protective pipe 7 and the movable semicircular protective pipe 9 without disassembling any parts. The two shielding lips 13 further ensure that the cable body 1 will not slip off from the other side, providing additional safety.

[0035] After the cable body 1 is placed, the operator rotates the operating block 11 to make the threaded rod 15 rotate, and drives the other threaded rod 15 to rotate synchronously through the synchronous chain 17. This causes the two nut pairs 16 to move synchronously, which in turn pushes the moving semi-circular ring 8 to move inward, so that the moving semi-circular ring protection pipe 9 gradually approaches the fixed semi-circular ring protection pipe 7 until it completely covers the cable body 1.

[0036] As the moving semi-ring protection pipe 9 approaches the fixed semi-ring protection pipe 7, the sealing gaskets 18 on the sealing lip 12 come into contact with each other and abut tightly, forming an effective sealing layer to prevent dust and other contaminants from entering the system.

[0037] 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.
