Description

Technical Field

[0001] The invention relates to the technical field of maintenance of a shift lever assembly, in particular to a connecting piece between a shift lever and a mounting base of an automobile. Background Art

[0002] The shift lever, also called the operating lever, is used on the car's transmission. Its main function is to support the car's gear shifting. When driving on different road conditions, the driver needs to constantly operate the shift lever according to the road conditions to adjust the car's gears to achieve the effect of accelerating or decelerating the car. Therefore, when the car is driving, the road conditions are complicated and gear shifting also needs to be done frequently. Especially for taxis, in order to increase the number of passengers they carry, taxi drivers will accelerate on wide and safe roads while driving safely, shortening the driving time and ensuring that passengers can reach their destination safely and quickly. Taxis can also change passengers to go to the next destination, increasing the driver's income. Therefore, in this process, the gear lever is frequently operated, causing the internal components of the gear lever to be accelerated. For general cars, when the driving range is greater than 100,000 kilometers, the gear lever assembly will be worn to the point where it is difficult to select and shift gears. When selecting and shifting gears is not sensitive, the car cannot quickly accelerate or decelerate according to the driver's wishes, which may lead to traffic accidents. Taxis travel 130,000 to 150,000 kilometers in half a year, so the car needs to be repaired and the gear lever assembly replaced every year.

[0003] In order to ensure driving safety, when the car driving range is about to reach 150,000 kilometers, the driver needs to send the car to the repair shop to replace and maintain the components. The connecting part between the shift lever and the mounting base is also called the selector plate, which is used to enable the driver to select the gear when operating the shift lever. When the shift lever is frequently operated, the selector plate becomes the part that is most easily worn. Therefore, during car maintenance, it is necessary to replace it to achieve the purpose of maintaining the gear selection sensitivity. When performing maintenance and replacement, it is necessary to use a lifter to lift the car as a whole, and remove the screws on the bottom plate of the car to fix it. The plate must be removed, and then the heat insulation plate under the shift lever and the mounting base must be removed before the shift lever and the mounting base can be observed. Then the shift cable and the selector cable at the end connected to the gear transmission must be removed before the entire shift base can be taken out. Finally, the connecting pins on the selector plate and the mounting base must be removed, and the parts must be replaced. The shift lever is considered repaired and replaced according to the above steps. The cumbersome maintenance steps increase the maintenance time, which in turn leads to high single maintenance costs, and the shift lever assembly of the taxi needs to be replaced frequently, which significantly increases the cost of using the taxi.

[0004] Therefore, in order to shorten the maintenance time, reduce the replacement steps, improve the maintenance efficiency and reduce the maintenance cost, a connecting piece between an automobile shift lever and a mounting base is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a connecting piece between a car shift lever and a mounting base, which can be modularly disassembled by disassembling the shift lever assembly, so that it can be quickly disassembled, replaced and installed. The disassembly device can achieve a quick release and installation effect, reduce maintenance steps, shorten maintenance time, and improve maintenance efficiency, so as to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A connecting piece between a shift lever and a mounting base of an automobile, comprising a shift lever, a connecting pin, a return spring, a shift plate, a base, a shift cable, a shift cable and a control system, wherein:

[0008] The base is installed inside the car, and a disassembly module for facilitating installation and disassembly is provided on the base. The disassembly module is threadedly connected to the base, the shift lever is movably installed on the disassembly module, the connecting pin is rotatably installed on the disassembly module, the selector plate is rotatably installed on the connecting pin and connected to the disassembly module via a return spring, the return spring is sleeved on the connecting pin, the shift cable is provided at the bottom of the shift lever, and the selector cable is provided at the bottom of the selector plate. Through the disassembly module, the required replacement parts can be disassembled and installed in smaller parts, thereby reducing the workload of maintenance and replacement and avoiding large-scale maintenance and disassembly work;

[0009] A disassembly device is provided on the base, and the disassembly device is used to quickly dismantle and install the shift cable and the gear selection cable, so that the disassembly module can be quickly taken out, which is convenient for maintenance personnel to replace worn parts, reduces the maintenance and replacement work steps, reduces the need for large-scale removal of parts during maintenance, prevents the occurrence of incomplete installation of parts, ensures the maintenance precision and accuracy, and thus ensures the originality of the car and the performance of the car.

[0010] Preferably, the disassembly device includes a cylinder, the cylinder is threadedly connected to the bottom of the base, the output shaft of the cylinder is threadedly connected to a push plate, a disassembly rod 1 is rotatably installed on the push plate, a disassembly rod 2 is rotatably installed on the push plate, a connecting plate is movably installed on the selector plate, the selector cable is rotatably installed on the connecting plate, a connecting block is movably installed on the shift lever, and the shift cable is rotatably installed on the connecting block, a disassembly switch for electrically connecting to the cylinder is installed on the base and on the side of the disassembly module, and a self-locking device for switching the locking position is provided in the connecting plate and the connecting block. Although the selector plate, connecting pin, shift lever and return spring that need to be replaced and maintained are all located on the disassembly module, the disassembly module can be removed during maintenance and replacement, but since the selector plate and shift lever need to be connected to the selector cable and shift lever The gear selection and shifting operations can be performed by pulling the wire. Therefore, this design adopts an indirect connection method. When removing the dismantling module, a working signal is sent to the cylinder through the dismantling switch, and the cylinder is used to drive the push plate, which in turn drives the dismantling rod one and the dismantling rod two to move, and cooperate with the connecting plate and the connecting block to drive the connecting plate and the connecting block to drive the gear selection wire and the shift wire to separate from the gear selection plate and the shift rod, ensuring that after the dismantling module is taken out, the gear selection wire and the shift wire will not be taken out together, and the deviation from their working position is not large, avoiding the problem of not being able to install and reset the gear selection wire and the shift wire after dismantling. While ensuring that the removal of the dismantling module is not affected by the gear selection wire and the shift wire, it also ensures that after the dismantling module is installed and reset, the gear selection wire and the shift wire can maintain their original horizontal position, which is convenient for quick installation and reset, and improves the efficiency of replacement work.

[0011] Preferably, the self-locking device includes a mounting rod 1, a mounting rod 1 is threadedly connected to the baffle plate, a mounting hole 1 is provided on the connecting plate, a clamping block 1 is movably installed in the mounting hole 1 and at a distance of 2 to 3 cm from the outlet of the mounting hole 1, a triggering block 1 is movably installed in the mounting hole 1 and at a distance of 1 to 2 cm from the bottom of the mounting hole 1, the triggering block 1 is connected to the bottom of the mounting hole 1 through a triggering spring 1, a mounting hole 2 is provided on the connecting plate, a clamping block 2 is movably installed in the mounting hole 2 and at a distance of 2 to 3 cm from the outlet of the mounting hole 2, a triggering block 2 is movably installed in the mounting hole 2 and at a distance of 1 to 2 cm from the bottom of the mounting hole 2, the triggering block 2 is connected to the bottom of the mounting hole 2 through a triggering spring 2, and the triggering block 1 and the clamping block 2 are connected through a connecting rod 1 The trigger block 2 is connected to the card block 1 through a connecting rod 2, and the shift lever is threadedly connected to the mounting rod 2. A mounting hole 3 is provided on the connecting block. A card block 3 is movably installed in the mounting hole 3 and at a distance of 2 to 3 cm from the outlet of the mounting hole 3. A trigger block 3 is movably installed in the mounting hole 3 and at a distance of 1 to 2 cm from the bottom of the mounting hole 3. The trigger block 3 is connected to the bottom of the mounting hole 3 through a trigger spring 3. A mounting hole 4 is provided on the connecting block. A card block 4 is movably installed in the mounting hole 4 and at a distance of 2 to 3 cm from the outlet of the mounting hole 4. A trigger block 4 is movably installed in the mounting hole 4 and at a distance of 1 to 2 cm from the bottom of the mounting hole 4. The trigger block 4 is connected to the bottom of the mounting hole 4 through a trigger spring 4. The trigger block 3 and the card block 4 are connected through a connecting rod. When the lever is in the first position, the spring will retract the trigger block, and the clamping block will be in the first position, so that the lever will be in the first position and the spring will retract the trigger block, which will in turn clamp the lever in the first position, thereby securing the lever and the second position. When the gear selector is removed, the cylinder moves back to the first dismantling rod, and the second dismantling rod is moved back to the second dismantling rod, and the second dismantling rod is moved back to the first dismantling rod. When the gear selector is removed, the cylinder moves back to the first dismantling rod, and the cylinder moves back to the second dismantling rod, and the cylinder moves back to the first dismantling rod, and the cylinder moves back to the second dismantling rod. When the gear selector is removed, the cylinder moves back to the first dismantling rod, and the cylinder moves back to the second dismantling rod. When the gear selector is removed, the cylinder moves back to the first dismantling rod, and the cylinder moves back to the second dismantling rod. When the cylinder moves back, the cylinder moves back to the first dismantling rod, and the cylinder moves back to the second dismantling rod. When the cylinder moves back, the cylinder moves back to the first dismantling rod, and the cylinder moves back to the second dismantling rod. When the cylinder moves back, the cylinder moves back to the second ...Therefore, it is only necessary to drive the cylinder to disengage or connect the gear selection cable and the gear shift cable from the gear selection plate and the gear shift lever through the connecting plate and the connecting block, use the self-locking effect of the card block and the plug rod, and unlock it with the principle of the lever slider, so that the connecting plate and the connecting block can be naturally switched and installed on the two contact rods, so that when the gear shifting work is performed, the disassembly device will not contact and affect the gear shifting work. When the replacement work is performed, it can ensure that the cable is separated from the components on the removal module, which does not affect the removal and replacement work, thereby improving the efficiency of the disassembly. The self-locking structure in this solution is not the only choice. An electromagnetic slider mechanism can be used to achieve a switching locking effect. The electromagnetic slider structure is relatively simpler and the unlocking method is easier and faster. However, since it needs to be powered on to unlock, the connecting plate and the connecting block always carry wires. During the gear shifting process, if the wires are entangled, it will affect the gear shifting effect. Therefore, the design of this solution effectively avoids this problem. When the gear shifting work is performed, the disassembly device will not affect the work, and the switching locking effect can also be achieved.

[0012] Preferably, the shift plate is provided with a non-rotating slot that cooperates with the connecting plate, and the connecting block is provided with a protrusion that cooperates with the shift lever. The connecting plate can fit with the slot to ensure that when the connecting plate is installed on the shift plate, it will not rotate due to lack of restriction, resulting in the shift plate being unable to effectively transmit power to the shift cable, thereby reducing the shift accuracy. Similarly, the connecting block can be restricted by the protrusion, and rotation will occur when the connecting block is installed on the shift lever, resulting in the shift lever being unable to effectively transmit power to the shift cable, thereby reducing the shift accuracy. While ensuring that it can be naturally disassembled and installed, it ensures stable transmission of power during shifting, thereby improving the accuracy of the installation work.

[0013] Preferably, the front ends of the disassembly rod 1, disassembly rod 2, installation rod 1 and installation rod 2 are all set to a frustum shape, which is used to expand the error range of the deviation of installation hole 1, installation hole 2, installation hole 3 and installation hole 4 when cooperating with the corresponding installation hole 1, installation hole 2, installation hole 3 and installation hole 4, so that the installation hole 1, installation hole 2, installation hole 3 and installation hole 4 are corrected by the inclined surface of the frustum and aligned with the disassembly rod 1, disassembly rod 2, installation rod 1 and installation rod 2 to ensure the accuracy of the disassembly and installation work and improve the work efficiency of disassembly and installation.

[0014] When the shift lever is in the vertical position and the bottom of the shift lever is at the lowest point, the limit block is squeezed, thereby squeezing the limit plate down and compressing the limit spring. The stop plate one and the stop plate two are lowered along with the limit plate, releasing the movement restriction of the push plate. When the shift lever is in the vertical position and the bottom of the shift lever is at the lowest point, the limit block is squeezed, thereby squeezing the limit plate down and compressing the limit spring. The stop plate one and the stop plate two are lowered along with the limit plate, releasing the movement restriction of the push plate. When the gear is engaged, since the limit block is not squeezed, the stop plate one limits the forward direction of the push plate, ensuring that even if the cylinder is suddenly started, the various components cannot be driven to move due to the restriction of the stop plate one. Similarly, during the installation work, the stop plate two limits the backward movement direction of the push plate, which provides a reliable guarantee for the installation work, improves the reliability of the disassembly device, and ensures the safety of the disassembly device in the disassembly and installation and waiting for work state.

[0015] Preferably, the limiting block is hemispherical. Since the shift lever has a movable angle of 360°, in order to ensure that the shift lever can effectively squeeze the limiting block, the limiting block adopts a hemispherical shape, which reduces the squeezing resistance, improves the efficiency of removing the restriction, and thus improves the working effect.

[0016] Preferably, a switch box is installed on the base, the disassembly switch is arranged in the switch box, and a button is arranged on the top of the switch box, the button is connected to the switch box through a switch spring, and a protective shell is slidably installed in the switch box, the protective shell is connected to the inner wall of the switch box through a protective spring, and an electromagnet is threaded on the inner wall of the switch box to protect the disassembly switch from being accidentally touched. Only when the electromagnet is energized, the protective shell is adsorbed, and the switch protection spring is squeezed, the button can enter the switch box by squeezing the switch spring, squeezing the disassembly switch to send a working signal to the cylinder. After the pressing is completed, the switch spring rebounds and the button leaves the disassembly switch, the electromagnet is powered off and demagnetized, the protective spring rebounds, and the protective shell isolates the button from the channel of the disassembly switch, protecting the disassembly switch from being accidentally touched, improving the safety of the disassembly device, ensuring the work safety of maintenance personnel, and preventing the cylinder from being accidentally started, causing unnecessary damage to the disassembly device components, affecting the disassembly efficiency.

[0017] Preferably, the gear selection cable is connected to the connecting plate through bolt column one, and the gear shift cable is connected to the connecting block through bolt column two. The threaded connection not only ensures that the cable can rotate during operation, but also the threaded connection has self-locking force. As long as there is no rotational motion at the connection, the connector will not produce large displacement deviation. At the same time, the installation and disassembly steps are simple and quick. The traditional installation method uses a clamping device to limit the left and right rotation of the cable. It is necessary to first insert the cable rotation into the connecting rod and then install the clamping device on the connecting rod. In this design, it is only necessary to screw the bolt column into the cable rotation and then tighten the bolt column to the connecting plate in the same direction, which reduces the coordination of parts, shortens the installation steps, and improves the efficiency of disassembly and replacement.

[0018] Preferably, a slide groove 1 is provided in the second mounting hole, a slider 1 is threadedly connected to the first demolition rod, the slider 1 cooperates with the slide groove 1, a scraper 1 is threadedly connected to the first demolition rod, a slide groove 2 is provided in the fourth mounting hole, a slider 2 is threadedly connected to the second demolition rod, the slider 2 cooperates with the second slide groove, and the second demolition rod is threadedly connected to the second scraper, an oil outlet hole 1 is provided in the second mounting hole, and an oil outlet hole 2 is provided in the fourth mounting hole. In order to make the shift assembly smoother, the connection between the parts in the shift assembly is lubricated by lubricating oil to improve the smoothness of operation. When the viscosity of the lubricating oil is low, leakage will occur and flow into the second mounting hole and the fourth mounting hole. Since the lubricating oil mixes with dust in the air after a certain period of time, the lubricating oil will be partially scaled. The scaling absorbs the lubricating oil, resulting in a reduction of the lubricating oil in the assembly, affecting the working effect. If the lubricating oil is not cleaned and added again, This results in an increase in the dosage of lubricating oil, which does not meet the specifications, creates greater pressure on the parts, and causes damage to the parts. Therefore, the slider one on the dismantling rod one cooperates with the slide groove one. When the dismantling rod one enters the mounting hole two, the dismantling rod one rotates in, causing the scraper one to scrape off the scale on the inner wall of the hole, and the scale pushed inward is discharged from the oil outlet hole one. When the dismantling rod one exits the mounting hole two, the slider one will drive the lubricating oil in the slide groove to discharge the mounting hole two. The cooperation of the dismantling rod two and the mounting hole four is the same. The lubricating oil is discharged from the oil outlet hole two to the outside of the mounting hole four through the cooperation of the slider two, the slide groove two, and the scraper two. During the dismantling work, a cleaning effect is achieved, making the matching parts smoother and improving the disassembly and installation efficiency. When the viscosity of the lubricating oil is high, no leakage will occur, but the friction will increase, the temperature of the gear shift lever assembly will rise rapidly, and it will be difficult to start under low temperature conditions. Therefore, using a lubricating oil with a lower viscosity can improve the smoothness of the gear shift.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The connecting piece between the shift lever and the mounting base of an automobile described in the present invention is constructed by installing the parts that are easily worn and need to be replaced on a disassembly module, which is installed on the base.

This allows maintenance personnel to directly remove the outer shell near the shift lever in the vehicle, then remove and replace the worn parts, thereby simplifying the maintenance work steps, shortening the maintenance time, improving the maintenance work efficiency, and reducing the maintenance cost.

[0021] 2. The connecting piece between the automobile shift lever and the mounting base described in the present invention enables the connecting piece to quickly switch the locking position through the self-locking device of the disassembly device, thereby realizing the function of rapid disassembly and installation, so that the connecting piece will not be affected by the disassembly device during the shifting operation, and can be quickly separated from the component during the disassembly work, thereby ensuring the positioning of the pull wire for easy installation and improving the work efficiency of disassembly and installation.

[0022] 3. The connecting piece between the automobile shift lever and the mounting base described in the present invention, through the cooperation of the limiting plate, limiting block, limiting spring, blocking plate 1 and blocking plate 2 of the disassembly device, makes the disassembly and installation work only required to meet relevant conditions to be carried out effectively, thereby improving the accuracy of the disassembly work, and at the same time preventing the cylinder from being started by mistake, causing related components to enter the shift working area, thereby affecting the shift work and reducing safety hazards when driving the vehicle.

Spring 41, button 40 presses down the disassembly switch 14, sends a working signal to the cylinder 8, removes the downward pressure of the button 40, the switch spring 41 rebounds the button 40 to the outside of the switch box 39, the electromagnet 44 is de-energized and demagnetized, the protection spring 43 rebounds the protection shell 42 to close the disassembly switch 14, the cylinder 8 drives the propulsion plate 9 forward, drives the disassembly rod 10 and the disassembly rod 2 11 to move, the slider 1 48 cooperates with the slide 1 47, drives the disassembly rod 10 to rotate along the slide, and the scraper 1 49 is pressed against the inner wall of the mounting hole 2 18 The lubricating oil is cleaned and the lubricating oil in the mounting hole 18 is pushed out from the oil outlet hole 53. The dismantling rod 10 squeezes the trigger block 26, compresses the trigger spring 230, and drives the block 21 to move through the connecting rod 56, releasing the restriction of the mounting rod 15. The connecting plate 12 and the dismantling rod 10 move, and the mounting rod 15 is separated from the mounting hole 17. The trigger spring 29 rebounds the trigger block 25, and drives the block 22 to lock the dismantling rod 10 through the connecting rod 55. The gear selection cable 7 is connected to the bolt column 45. The connecting plate 12 moves together. While the dismantling rod 10 is working, the dismantling rod 2 11 removes the connecting block 13 from the shift lever 1 in the same way. The shift cable 6 moves together with the connecting block 13 through the bolt column 2 46. The maintenance personnel can take out the dismantling module 59 and replace the parts that need to be replaced. The limiting block 36 loses the squeezing of the shift lever 1, the limiting spring 35 rebounds, the limiting plate 34 resets, and drives the limiting block 36 to reset. The blocking plate 2 38 limits the retreat direction of the propulsion plate 9, and the dismantling work is completed.

[0046] After the worn parts on the disassembly module 59 are replaced, the installation work begins. The disassembly module 59 is installed back on the base 5, the shift lever 1 is adjusted to a vertical state, the limit block 36 is squeezed again, the limit plate 34 is pressed down, the limit spring 35 is squeezed, the blocking plate 2 38 is lowered, and the electromagnet 44 is energized again to release the false touch protection. The button 40 is pressed to trigger the disassembly switch 14. The cylinder 8 receives the signal and starts working, driving the push plate 9 to retract, thereby driving the disassembly rod 10 and the disassembly rod 2 11 to move, and then driving the connecting plate 12 and the connecting block 13 to move, and the installation rod 15 enters the installation hole 17. Inside, the trigger block 25 is squeezed, the trigger spring 29 is squeezed, and the clamping block 22 is driven to move through the connecting rod 55, thereby releasing the restriction on the dismantling rod 10. The dismantling rod 10 continues to move with the cylinder 8 to push out the mounting hole 2 18, and the trigger block 26 loses the squeezing force. The trigger spring 2 30 rebounds the trigger block 26, and the clamping block 21 is driven to move through the connecting rod 56, thereby locking the mounting rod 15. The connecting plate 12 is reset and installed on the selector plate 4. At the same time as the connecting plate 12 is reset, the connecting block 13 is installed back on the shift lever 1 in the same way. The dismantling rod 11 is separated from the connecting block 13, and the installation work is completed.

[0047] Example 2, as Figures 1 to 13 As shown, this embodiment is suitable for working environments where the viscosity of the lubricating oil is above 110, specifically as follows:

[0048] In this embodiment, the slide groove 47, the slider 48, the scraper 49, the slide groove 50, the slider 51 and the scraper 52 are removed, and the dismantling rod 10 and the dismantling rod 11 are changed from a rotating installation to a fixed installation on the push plate 9. When the dismantling work is performed, the cylinder 8 drives the push plate 9 forward, driving the dismantling rod 10 and the dismantling rod 11 to move forward and enter the mounting hole 2 18 and the mounting hole 4 20. The self-locking device releases the lock on the mounting rod 15 and the mounting rod 2 16, so that the connecting plate 12 and the connecting block 13 are separated from the selector plate 4 and the shift lever 1, completing the dismantling work. The installation work is the same as that of the embodiment.

[0049] Compared with the embodiment 1, in the embodiment 2, since the viscosity of the lubricating oil is above 110, the viscosity is relatively large and it is not easy to flow, so it is not easy to enter the second mounting hole 18 and the fourth mounting hole 20, which has little effect on the disassembly and installation of the first and second disassembly rods 10 and 11. Therefore, the chute 1 47, the slider 1 48, the scraper 1 49, the chute 2 50, the slider 2 51 and the scraper 2 52 can be removed, and the rotating installation of the first and second disassembly rods 10 and 11 can be changed to a fixed installation on the push plate 9 to ensure that the first and second disassembly rods 10 and 11 are fixed on the push plate 9. The stability during disassembly and installation is improved by reducing the resistance of disassembly rod 10 and disassembly rod 2 11, making the disassembly and installation of connecting plate 12 and connecting block 13 faster and more efficient. However, if the lubricating oil viscosity is too high, the friction of the parts will increase during operation, the temperature will rise, and it will be difficult to start at low temperatures, which will lead to slow and difficult start-up. Low lubricating oil viscosity can avoid this problem, reducing friction, slowing the temperature rise rate, and enhancing fluidity, which will cause the lubricating oil to leak and flow to other places. In summary, if there is no strict requirement to control the leakage of lubricating oil, it is more appropriate to use a structure with slide groove 1 47, slider 1 48, scraper 1 49, slide groove 2 50, slider 2 51 and scraper 2 52.
