Description

Technical Field

[0001] This utility model belongs to the field of compensator technology, specifically relating to a cable compensator for automobiles. Background Technology

[0002] A compensator is a device used to regulate and compensate for changes in displacement, tension, pressure, etc., in a mechanical system caused by temperature variations, load changes, vibration, or other external factors. Its main purpose is to ensure that the system can operate stably and reliably under various working conditions, and to reduce stress concentration, wear, or failure caused by external changes.

[0003] In current automotive cable compensators applications, traditional lubrication methods reveal several significant limitations: First, to ensure normal equipment operation, existing compensators must be periodically shut down and partially disassembled to replenish lubricant after a period of use. This directly leads to interruptions in vehicle or machinery operation, severely reducing work efficiency. Especially during continuous operation or high-intensity work, prolonged downtime negatively impacts overall production progress or travel plans. Second, frequent disassembly and lubrication replenishment greatly increases maintenance complexity, requiring specialized technicians. This not only consumes significant manpower and time but also carries the risk of insufficient or excessive lubrication due to human error, affecting equipment performance and lifespan. Third, disassembling and reinstalling compensators poses potential safety risks, especially when performed while the vehicle is moving or the machinery is running. This can easily lead to accidents, threatening the personal safety of operators and the safety of the equipment. Furthermore, traditional lubrication methods are prone to uneven lubrication, with some areas insufficiently lubricated while others are over-lubricated, adversely affecting equipment stability and reliability. Finally, frequent downtime and manual maintenance significantly increase the total operating costs of the equipment, including labor costs, material costs, and production losses or travel delays caused by downtime. In summary, traditional lubrication methods have significant shortcomings in terms of efficiency, cost, safety, and lubrication effect, and there is an urgent need for a more efficient and automated lubrication solution to improve the overall performance of equipment and the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a cable compensator for automobiles, in order to solve the problems mentioned in the background art, which are caused by the need for periodic shutdowns to disassemble and replenish lubricant, resulting in low efficiency, complex maintenance, high safety risks, uneven lubrication and increased costs. There is an urgent need for a more efficient and automated solution to improve the overall performance and user experience of automobile cable compensators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable compensator for automobiles, comprising: a cable compensator for automobiles and a junction box;

[0006] The automotive cable compensator includes a first sleeve with a first groove inside. A first connecting rod is located inside the first groove. A first spring is connected to the first connecting rod and the first groove. A second sleeve is connected to the end of the first connecting rod outside the first groove. A second sleeve has a second groove inside. A second connecting rod is located inside the second groove. A second spring is connected to the second connecting rod and the second groove. A third connecting rod is connected to the end of the second connecting rod outside the second groove. A fourth connecting rod is connected to the side wall of the third connecting rod. A fifth connecting rod is connected to the side wall of the fourth connecting rod. A hollow cylinder is fitted around the fifth connecting rod. A hollow groove is located inside the hollow cylinder, and the fifth connecting rod can move within the hollow groove.

[0007] The outer wall of the first sleeve is fitted with a storage cylinder, and a piston plate is provided inside the storage cylinder. A fixing rod is connected to the side wall of the piston plate, and a receiving plate is installed at the end of the fixing rod away from the piston plate. A first fixing plate is installed on the outer wall of the third connecting rod, and a connecting plate is installed between the first fixing plate and the receiving plate. A liquid outlet pipe is connected to the liquid outlet end of the storage cylinder, and a liquid guide pipe is connected to the side wall of the liquid outlet pipe. The liquid outlet end of the liquid guide pipe extends into the first sleeve groove and the second sleeve groove. A pushing component is provided on one side of the receiving plate. The liquid guide pipe adopts a flexible hose design, which ensures the normal delivery of lubricant when the second sleeve moves.

[0008] Preferably, the pushing assembly includes a second fixed plate, a second guide cylinder, a second guide rod, and a fourth spring. The second fixed plate is installed on the outer wall of the first sleeve, the second guide cylinder is installed on the side wall of the second fixed plate, the second guide rod is installed on the side wall of the receiving plate, and a portion of the second guide rod is located inside the second guide cylinder. The fourth spring connects the second fixed plate and the receiving plate.

[0009] The first sleeve, the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod are all provided with wire grooves.

[0010] Through the above technical solution:

[0011] In use, the first sleeve, first connecting rod, second connecting rod, third connecting rod, and fourth connecting rod all have grooves for the cable. The pull cable passes through these grooves, connects to the fifth connecting rod, and extends out. During compensation, the first spring activates first, and its elastic force pushes the first connecting rod along the direction of the first groove. The displacement of the first connecting rod is transmitted to the second connecting rod through the second sleeve. At this time, the second spring is triggered, and its elastic force pushes the second connecting rod along the direction of the second groove. The movement of the second connecting rod then drives the third and fourth connecting rods to move together. This coordinated movement ultimately causes the fifth connecting rod to move along the direction of the hollow groove, pulling the pull cable and thus compensating for the tension in the pull cable.

[0012] As the third connecting rod performs the aforementioned movement, the first fixed plate on it also moves accordingly. The first fixed plate transmits the movement to the receiving plate via the connecting plate, and the receiving plate, in turn, drives the piston plate to move within the storage cylinder via the fixed rod. The storage cylinder contains lubricant, and when the piston plate moves, it compresses the lubricant within the storage cylinder. After being compressed, the lubricant is transported to the first and second sets of tanks via the liquid outlet and liquid guide pipes, achieving automatic lubrication replenishment for each moving part.

[0013] To ensure smooth lubricant flow and prevent jamming, the fourth spring plays a crucial role. Connected between the second fixed plate and the receiving plate, the fourth spring provides continuous thrust, assisting the receiving plate in moving and thus propelling the lubricant flow. The design of the second guide rod and the second guide cylinder further ensures precise horizontal displacement of the receiving plate. This not only facilitates smooth movement of the piston plate within the storage cylinder but also guarantees even distribution of lubricant to all areas requiring lubrication.

[0014] Through the above process, the cable compensator achieves precise compensation for cable tension. Simultaneously, the automatic lubrication system ensures that all moving parts receive adequate lubrication protection during operation. This collaborative working mechanism not only improves the compensator's response speed and accuracy but also extends its service life and reduces maintenance requirements.

[0015] The junction box is mounted on one end of the fifth connecting rod and is detachable. It reduces complex wiring requirements, making the wiring harness simpler. In automobiles, where wiring space is limited, the junction box can centrally manage multiple lines, reducing the number and complexity of wiring harnesses, thereby saving space and improving wiring reliability.

[0016] In summary, this automotive cable compensator achieves automatic compensation of cable tension through the synergistic action of elastic elements such as the first and second springs; it achieves automatic replenishment and distribution of lubricant through the cooperation of components such as the piston plate, storage cylinder, and fluid guide pipe; and the design of the fourth spring and second guide rod ensures the stability and reliability of the entire system during operation. This design not only improves the performance of the compensator but also enhances its adaptability and durability under various operating conditions.

[0017] The first sleeve is fitted with a protective plate, which is circular in shape, and multiple elastic components are installed between the protective plate and the first sleeve.

[0018] Preferably, the elastic component includes a third guide cylinder, a fourth guide rod, a fifth spring, and a rubber strip. The third guide cylinder is movably mounted on the inner wall of the protective plate, the fourth guide rod is movably mounted on the outer wall of the first sleeve, and a portion of the fourth guide rod is located inside the third guide cylinder. The fifth spring is connected between the third guide cylinder and the fourth guide rod, and the rubber strip is installed between the protective plate and the first sleeve.

[0019] Through the above technical solution:

[0020] In use, a protective plate is installed on the outer side of the first sleeve while the car is in motion. This protective plate is fixed to other parts of the car via a specific connection method. When the car travels on bumpy roads, relative movement occurs between the protective plate and the first sleeve. At this time, the elastic component begins to function. The fourth guide rod slides or moves within the third guide cylinder, which acts as a guiding structure to ensure the stable and controllable movement of the fourth guide rod. A fifth spring connects the third guide cylinder and the fourth guide rod. When the fourth guide rod moves, the fifth spring is compressed or stretched, generating elastic force. This elastic force effectively absorbs and dissipates vibration and impact energy from the road surface, reducing the impact of bumps on the first sleeve. A rubber strip is installed between the protective plate and the first sleeve. When compressed, the rubber strip deforms, further absorbing and buffering the remaining vibration and impact. This dual shock absorption mechanism of springs and rubber ensures the stability of the first sleeve in bumpy environments.

[0021] Through the coordinated operation of the aforementioned elastic components, the first sleeve can maintain a relatively stable state during vehicle operation, reducing the interference of external vibrations and impacts on its internal structure. This is specifically reflected in the following aspects:

[0022] Reduced longitudinal force interference: The interference of longitudinal forces on the compensator is significantly reduced. This is because the elastic components effectively absorb and disperse these forces, allowing the first sleeve to operate more smoothly.

[0023] Improved precision: With the stability of the first sleeve ensured, the cable tension compensation process within the compensator can be performed more precisely. This is crucial for the overall performance of the automotive cable system, especially in systems requiring high-precision operation such as braking, accelerator, and gear shifting.

[0024] Comprehensive protection: The combination of the protective plate and the elastic component provides the first sleeve with a comprehensive protection system that can effectively cope with various external impacts and vibrations.

[0025] Significant shock absorption effect: The dual shock absorption mechanism of the fifth spring and rubber strip ensures the stability of the first sleeve in bumpy environments and reduces the interference of longitudinal force on the compensator.

[0026] Extended service life: Reduces the damage to the compensator caused by vibration and shock, extends the service life of the compensator, and reduces the frequency of maintenance and replacement.

[0027] Preferably, a rack is installed on the outer wall of the fifth connecting rod, a mounting plate is provided on one side of the rack, a toothed block is installed on the end of the mounting plate near the rack, and the rack and the toothed block are adapted to each other. A cover is installed on the outer wall of the hollow cylinder, a third spring is connected between the mounting plate and the cover, a first guide cylinder is installed on the inner wall of the cover, a first guide rod is installed on the side wall of the mounting plate, and a portion of the first guide rod is located inside the first guide cylinder. The cover and the hollow cylinder are detachable and can be manually operated so that the fifth connecting rod can return to its original position.

[0028] Specifically, if the cable tension changes and requires compensation during vehicle movement, the fifth connecting rod will move accordingly. The hollow cylinder is securely fixed to a specific component of the vehicle, providing solid support for the movement of the fifth connecting rod. As the fifth connecting rod moves, the rack on its outer wall moves synchronously, with the toothed blocks meshing along the rack's teeth and pushing the mounting plate above. At this time, the third spring is compressed, absorbing and dissipating some of the kinetic energy to ensure smooth movement. Simultaneously, the first guide rod and the first guide cylinder cooperate to ensure that the mounting plate is not prone to shifting or wobbling during movement.

[0029] By utilizing the meshing motion of the rack and pinion, the fifth connecting rod achieves a unidirectional compensation length function, meaning it can only extend for compensation and cannot retract. This design not only improves the motion accuracy and stability of the compensator but also enhances its adaptability and reliability under various working conditions, effectively ensuring the accuracy and safety of wire tension compensation.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] (1) This utility model achieves automatic lubricant replenishment by setting up components such as a third connecting rod, a fixed rod, a piston plate, and a storage cylinder. When the third connecting rod moves, the first fixed plate on it moves accordingly, and the first fixed plate transmits the movement to the receiving plate through the connecting plate. The receiving plate then drives the piston plate to move inside the storage cylinder through the fixed rod. The lubricant stored in the storage cylinder is transported to the first and second sets of tanks through the liquid outlet pipe and the liquid guide pipe under the squeezing action of the piston plate, thereby realizing automatic lubrication replenishment for each moving part. This design not only automatically replenishes the lubricant, but also ensures that each moving part is continuously lubricated during operation, effectively reducing component wear and thus extending the service life of the equipment.

[0032] (2) This utility model constructs an efficient protection and shock absorption system for the car cable compensator by setting key components such as a protective plate, a fifth spring, and a rubber strip. When the car is driving, especially on bumpy roads, the fifth spring generates elastic force through compression or stretching, effectively absorbing and dissipating the vibration and impact energy of the road surface. The rubber strip deforms when compressed, providing secondary buffering for the remaining vibration and impact, thereby significantly reducing the direct impact on the compensator. The third guide cylinder, as a guiding structure, ensures that the movement direction of the fourth guide rod is stable and controllable. Attached Figure Description

[0041] 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.

[0042] Please see Figures 1-5 As shown, this utility model provides the following technical solution: a cable compensator for automobiles, comprising: a cable compensator for automobiles and a junction box 40;

[0043] The automotive cable compensator includes a first sleeve 1, a first groove 2 inside the first sleeve 1, a first connecting rod 3 inside the first groove 2, a first spring 4 connected to the first connecting rod 3 inside the first groove 2, a second sleeve 5 connected to the end of the first connecting rod 3 outside the first groove 2, a second groove 6 inside the second sleeve 5, a second connecting rod 7 inside the second groove 6, a second spring 8 connected to the second connecting rod 7 inside the second groove 6, a third connecting rod 9 connected to the end of the second connecting rod 7 outside the second groove 6, a fourth connecting rod 10 connected to the side wall of the third connecting rod 9, a fifth connecting rod 11 connected to the side wall of the fourth connecting rod 10, a hollow cylinder 12 fitted around the fifth connecting rod 11, a hollow groove 13 inside the hollow cylinder 12, and the fifth connecting rod 11 can move within the hollow groove 13;

[0044] A storage cylinder 23 is installed on the outer wall of the first sleeve 1. A piston plate 24 is provided inside the storage cylinder 23. A fixing rod 25 is connected to the side wall of the piston plate 24. A receiving plate 26 is installed at the end of the fixing rod 25 away from the piston plate 24. A first fixing plate 27 is installed on the outer wall of the third connecting rod 9. A connecting plate 28 is installed between the first fixing plate 27 and the receiving plate 26. A liquid outlet pipe 33 is connected to the liquid outlet end of the storage cylinder 23. A liquid guide pipe 34 is connected to the side wall of the liquid outlet pipe 33. The liquid outlet end of the liquid guide pipe 34 extends into the first sleeve 2 and the second sleeve 6. A pushing component is provided on one side of the receiving plate 26. The liquid guide pipe 34 adopts a flexible hose design, which can ensure the normal delivery of lubricant when the second sleeve 5 moves.

[0045] Furthermore, the pushing assembly includes a second fixing plate 29, a second guide cylinder 30, a second guide rod 31, and a fourth spring 32. The second fixing plate 29 is installed on the outer wall of the first sleeve 1, the second guide cylinder 30 is installed on the side wall of the second fixing plate 29, the second guide rod 31 is installed on the side wall of the receiving plate 26, and a portion of the second guide rod 31 is located inside the second guide cylinder 30. The fourth spring 32 connects the second fixing plate 29 and the receiving plate 26.

[0046] The first sleeve 1, the first connecting rod 3, the second connecting rod 7, the third connecting rod 9, and the fourth connecting rod 10 are all provided with wire grooves.

[0047] Through the above technical solution:

[0048] In use, grooves are formed inside the first sleeve 1, first connecting rod 3, second connecting rod 7, third connecting rod 9, and fourth connecting rod 10. The pull wire passes through these grooves, connects to the fifth connecting rod 11, and extends out. During compensation, the first spring 4 activates first, and its elastic force pushes the first connecting rod 3 along the direction of the first groove 2. The displacement of the first connecting rod 3 is transmitted to the second connecting rod 7 through the second sleeve 5. At this time, the second spring 8 is triggered, and its elastic force pushes the second connecting rod 7 along the direction of the second groove 6. The movement of the second connecting rod 7 then drives the third connecting rod 9 and the fourth connecting rod 10 to move together. This coordinated movement ultimately causes the fifth connecting rod 11 to move along the direction of the hollow groove 13, pulling the pull wire and thus compensating for the tension of the pull wire.

[0049] While the third connecting rod 9 is moving as described above, the first fixed plate 27 on it also moves accordingly. The first fixed plate 27 transmits the movement to the receiving plate 26 through the connecting plate 28, and the receiving plate 26, in turn, drives the piston plate 24 to move within the storage cylinder 23 through the fixed rod 25. The storage cylinder 23 stores lubricant, and when the piston plate 24 moves, it exerts a squeezing effect on the lubricant within the storage cylinder 23. After being squeezed, the lubricant is transported to the first set of tanks 2 and the second set of tanks 6 through the liquid outlet pipe 33 and the liquid guide pipe 34, thereby achieving automatic lubrication replenishment for each moving part.

[0050] To ensure smooth lubricant flow and prevent jamming, the fourth spring 32 plays a crucial role. Connected between the second fixed plate 29 and the receiving plate 26, the fourth spring 32 provides continuous thrust, assisting the movement of the receiving plate 26 and thus promoting lubricant flow. The design of the second guide rod 31 and the second guide cylinder 30 further ensures precise horizontal displacement of the receiving plate 26. This not only facilitates the smooth movement of the piston plate 24 within the storage cylinder 23 but also ensures that the lubricant is evenly distributed to all lubrication points. It is important to note that there is a certain degree of sealing between the first sleeve 1 and the second sleeve 5, and between the second sleeve 5 and the third connecting rod 9, thus preventing lubricant leakage from the first groove 2 and the second groove 6. Figure 5 The position shown is the compensation limit position.

[0051] Through the above process, the cable compensator achieves precise compensation for cable tension. Simultaneously, the automatic lubrication system ensures that all moving parts receive adequate lubrication protection during operation. This collaborative working mechanism not only improves the compensator's response speed and accuracy but also extends its service life and reduces maintenance requirements.

[0052] Junction box 40 is mounted on one end of the fifth connecting rod 11 and is detachable. Junction box 40 can reduce complex wiring requirements and make the wiring harness simpler. In automobiles, wiring space is limited. Junction box 40 can centrally manage multiple lines, reducing the number and complexity of wiring harnesses, thereby saving space and improving wiring reliability.

[0053] In summary, this automotive cable compensator achieves automatic compensation of cable tension through the synergistic action of elastic elements such as the first spring 4 and the second spring 8; it achieves automatic replenishment and distribution of lubricant through the cooperation of components such as the piston plate 24, the storage cylinder 23, and the fluid guiding pipe 34; and the design of the fourth spring 32 and the second guide rod 31 ensures the stability and reliability of the entire system during operation. This design not only improves the performance of the compensator but also enhances its adaptability and durability under various working conditions.

[0054] Please see Figures 1-6As shown, a protective plate 35 is fitted on the outer side of the first sleeve 1. The protective plate 35 is circular, and multiple elastic components are installed between the protective plate 35 and the first sleeve 1.

[0055] Furthermore, the elastic component includes a third guide cylinder 36, a fourth guide rod 37, a fifth spring 38, and a rubber strip 39. The third guide cylinder 36 is movably mounted on the inner wall of the protective plate 35, the fourth guide rod 37 is movably mounted on the outer wall of the first sleeve 1, and a portion of the fourth guide rod 37 is located inside the third guide cylinder 36. The fifth spring 38 is connected between the third guide cylinder 36 and the fourth guide rod 37, and the rubber strip 39 is installed between the protective plate 35 and the first sleeve 1.

[0056] Through the above technical solution:

[0057] In use, during vehicle operation, a protective plate 35 is installed on the outer side of the first sleeve 1, which is fixed to other components of the vehicle via a specific connection method. When the vehicle travels on bumpy roads, relative movement occurs between the protective plate 35 and the first sleeve 1. At this time, the elastic component begins to function. The fourth guide rod 37 slides or moves within the third guide cylinder 36, which acts as a guide structure to ensure the stable and controllable movement direction of the fourth guide rod 37. The fifth spring 38 connects the third guide cylinder 36 and the fourth guide rod 37. When the fourth guide rod 37 moves, the fifth spring 38 is compressed or stretched, thereby generating elastic force. This elastic force effectively absorbs and dissipates vibration and impact energy from the road surface, reducing the impact of bumps on the first sleeve 1. A rubber strip 39 is installed between the protective plate 35 and the first sleeve 1. When compressed, the rubber strip 39 deforms, further absorbing and buffering the remaining vibration and impact. This dual shock absorption mechanism of spring and rubber ensures the stability of the first sleeve 1 in bumpy environments.

[0058] Through the coordinated operation of the aforementioned elastic components, the first sleeve 1 can maintain a relatively stable state during vehicle operation, reducing the interference of external vibrations and impacts on its internal structure. This is specifically reflected in the following aspects:

[0059] Reduced longitudinal force interference: The interference of longitudinal forces on the compensator is significantly reduced. This is because the elastic components effectively absorb and disperse these forces, allowing the first sleeve 1 to operate more smoothly.

[0060] Improved precision: With the stability of the first sleeve 1 guaranteed, the cable tension compensation process inside the compensator can be performed more precisely. This is crucial for the overall performance of the automotive cable system, especially in systems requiring high-precision operation such as braking, accelerator, and gear shifting.

[0061] Comprehensive protection: The combination of the protective plate 35 and the elastic component provides a comprehensive protection system for the first sleeve 1, which can effectively cope with various external impacts and vibrations.

[0062] Significant shock absorption effect: The dual shock absorption mechanism of the fifth spring 38 and rubber strip 39 ensures the stability of the first sleeve 1 in a bumpy environment and reduces the interference of longitudinal force on the compensator.

[0063] Extended service life: Reduces the damage to the compensator caused by vibration and shock, extends the service life of the compensator, and reduces the frequency of maintenance and replacement.

[0064] For further details, please refer to Figure 1 , Figure 5 and Figure 7 As shown, a rack 17 is installed on the outer wall of the fifth connecting rod 11. A mounting plate 18 is provided on one side of the rack 17. A toothed block 19 is installed on the end of the mounting plate 18 near the rack 17, and the rack 17 and the toothed block 19 are compatible. A cover 14 is installed on the outer wall of the hollow cylinder 12. A third spring 20 is connected between the mounting plate 18 and the cover 14. A first guide cylinder 21 is installed on the inner wall of the cover 14. A first guide rod 22 is installed on the side wall of the mounting plate 18, and part of the first guide rod 22 is located inside the first guide cylinder 21. The cover 14 and the hollow cylinder 12 are detachable and can be manually operated so that the fifth connecting rod 11 can return to its original position.

[0065] Specifically, if the cable tension changes and requires compensation during vehicle operation, the fifth connecting rod 11 will move accordingly. The hollow cylinder 12 is securely fixed to a specific component of the vehicle, providing solid support for the movement of the fifth connecting rod 11. As the fifth connecting rod 11 moves, the rack 17 on its outer wall moves synchronously, and the toothed block 19 engages along the tooth profile of the rack 17, pushing the mounting plate 18 above. At this time, the third spring 20 is compressed, absorbing and dissipating some of the kinetic energy, thereby ensuring the smoothness of the movement. Simultaneously, the first guide rod 22 and the first guide cylinder 21 cooperate to ensure that the mounting plate 18 is not prone to displacement or wobbling during movement.

[0066] With the meshing motion of rack 17 and toothed block 19, the fifth connecting rod 11 achieves the function of unidirectional compensation length, that is, it can only extend for compensation and cannot retract. This design not only improves the motion accuracy and stability of the compensator, but also enhances its adaptability and reliability under various working conditions, effectively ensuring the accuracy and safety of wire tension compensation.

[0067] 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.
