Description

Technical Field

[0001] The present application relates to the technical field of automobile control devices, and in particular to a manual transmission joystick air supply pipeline installation structure and method. Background Art

[0002] Manual transmissions are now a common feature on gasoline-powered vehicles. Models equipped with manual transmissions all feature a joystick next to the driver's seat. The joystick is typically made of round steel, with an operating handle (commonly known as a ball joint) attached to the end. The ball joint is printed with the gear position symbol. The ball joint is threaded to the joystick. For decorative purposes, the joystick is typically hidden from view. The ball joint is located above, and a soft protective cover is placed below the ball joint. The upper portion of the protective cover fits over the round joystick, while the lower portion is secured to a decorative plastic base with a snap-on design.

[0003] In related technology, the joystick can be in different positions when shifting gears. For medium and heavy-duty trucks, compressed air is typically used to control the transmission's gear changes. This involves connecting a compressed air supply line to the ball joint. Commonly used lines are nylon lines with an outer diameter of 4mm, with two or three per vehicle. Similarly, after assembly, the air pipes are located inside the protective cover and are not visible from the outside. The assembly sequence for this structure is as follows:

[0004] 1. The control mechanism assembly with integrated joystick is installed on the cab floor;

[0005] 2. Run the air pipe along the joystick and tie it to the joystick body with a cable tie to prevent it from falling off. The end should be flush with or higher than the top of the joystick.

[0006] 3. Install the plastic decorative base on the cab floor;

[0007] 4. Install the soft shield. The lower end of the shield is snapped onto the plastic decorative base, and the upper end is fitted with the shift lever. The shift lever air pipe extends from the upper end of the shield.

[0008] 5. Install the ball joint to the joystick, then connect the air hose to the ball joint. If the air hose is too long, shorten it.

[0009] However, the disadvantage of this assembly method is that the tubing must be completely hidden within the shroud after installation. If the shroud is left uncovered during assembly, the narrow opening at the top makes it difficult to connect the tubing to the ball joint. If the tubing is pulled out before connecting to the ball joint, the tubing must be pushed back into the shroud after assembly. Nylon tubing is relatively stiff and difficult to manipulate. Furthermore, since the middle of the tubing is already tied to the joystick, the retracted tubing cannot be extended and will bulge out under the ball joint, creating a bulge on the soft shroud, severely degrading the appearance. Without direct access to the tubing, adjustments are impossible. Furthermore, if cable ties are not used at all, the cable ties are placed around the ball joint mounting point at the top of the joystick in step 2 and then cut when the ball joint is installed. While this method makes retraction easier, the position of the excess length cannot be controlled, and there is still a chance of lifting the shroud. Summary of the Invention

[0036] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The embodiments of the present application provide a manual transmission lever air supply pipe installation structure and method, which can solve the problem in the related art that the manual transmission lever air supply pipe easily pushes up the shield and causes a bulge, resulting in poor interior assembly quality.

[0038] See also Figure 1 and Figure 2 As shown, the first aspect of the embodiment of the present application provides a manual transmission joystick air supply pipeline installation structure, comprising:

[0039] The joystick assembly includes a joystick body 4 and an operating handle 1 connected to the top of the joystick body 4;

[0040] The tracheal body 2 is wrapped around the outside of the joystick body 4 and connected to the operating handle 1;

[0041] Fastening assembly: the trachea body 2 is fixed to the joystick body 4 through the fastening assembly.

[0042] The joystick assembly of the manual transmission joystick air supply line mounting structure of the present embodiment includes a joystick body 4 and an operating handle 1 connected to the top of the joystick body 4. The air tube body 2 is wrapped around the outside of the joystick body 4 and connected to the operating handle 1. The air tube body 2 is also fixed to the joystick body 4 via a fastening assembly. During use, the fastening assembly and the operating handle 1 can accommodate a longer air tube body 2. The air tube body 2 is wrapped around the joystick body 4 between the fastening assembly and the operating handle 1 without forming a bulge that would lift the protective cover, thereby preventing the protective cover from affecting its appearance, thereby ensuring the quality of the interior assembly.

[0043] It should be noted that in this embodiment, there are no specific requirements or special limitations on the structural features such as the size, shape and material of the fastening assembly. The function of the fastening assembly in this embodiment is to cooperate with the operating handle 1 so that the trachea body 2 between the fastening assembly and the operating handle 1 is maintained on the outside of the joystick body 4 in a winding manner. Therefore, it can be understood that other fastening assemblies that can achieve such functions can be used in this embodiment. Those skilled in the art can adaptively adjust the size, shape and structure of the fastening assembly according to the usage scenario and test conditions. In addition, the shield is not drawn in the figure.

[0044] In some alternative embodiments: See Figure 1 and Figure 2 As shown, the embodiment of the present application provides a manual transmission joystick air supply pipe installation structure, the fastening assembly of the manual transmission joystick air supply pipe installation structure includes a connecting sleeve 5 connected to the joystick body 4 at one end away from the operating handle 1, the connecting sleeve 5 is connected to a pipe clamp 3 for fixing the air pipe body 2 to the connecting sleeve 5, and the pipe clamp 3 is fixed to the side wall of the connecting sleeve 5 by screws 6;

[0045] The joystick body 4 is provided with a first external thread adapted to the connecting sleeve 5, and the joystick body 4 is provided with a second external thread adapted to the operating handle 1, and the directions of the first external thread and the second external thread are opposite;

[0046] The connecting sleeve 5 is made of plastic.

[0047] The fastening assembly of the manual transmission joystick air supply pipe mounting structure of the embodiment of the present application includes a connecting sleeve 5 that is away from one end of the operating handle 1 and is threadedly connected to the joystick body 4. A pipe clamp 3 is installed on the connecting sleeve 5 to fix the air pipe body 2 on the connecting sleeve 5. The pipe clamp 3 is fixedly mounted on the side wall of the connecting sleeve 5 by a screw 6. A blind hole that is compatible with the screw 6 is provided on the connecting sleeve 5. A first external thread that is compatible with the connecting sleeve 5 is provided on the joystick body 4. A second external thread that is compatible with the operating handle 1 is provided on the joystick body 4. The directions of the first external thread and the second external thread are opposite. The connecting sleeve 5 is made of plastic.

[0048] During specific use, the connecting sleeve 5 is screwed into the first external thread on the joystick body 4, and a section of the first external thread is left above the connecting sleeve 5, so that the trachea body 2 passes through the pipe clamp 3, and the screw 6 is screwed into the blind hole on the connecting sleeve 5. The screw 6 is installed through the pipe clamp 3. After the screw 6 is screwed into place, the pipe clamp 3 clamps and positions the trachea body 2, and then the trachea body 2 is inserted into the operating handle 1, and the operating handle 1 is screwed into the second external thread on the joystick body 4. The operating handle 1 drives the plug-in fixed end of the trachea body 2 to move circumferentially around the operating handle 1, and the trachea body 2 drives the connecting sleeve 5 to rotate upward along the first external thread on the joystick body 4 to wrap the trachea body 2 around the outside of the joystick body 4. It should be noted that during the specific operation process, the operating handle 1 can also be screwed into the second external thread on the joystick body 4, and the operating handle 1 should not be tightened first. Three to four turns of thread are reserved below the operating handle 1, and then the trachea body 2 is plugged into the trachea connector on the operating handle 1. Then the operating handle 1 is tightened into place. The operating handle 1 drives the plug-in fixed end of the trachea body 2 to move circumferentially around the operating handle 1, and the trachea body 2 drives the connecting sleeve 5 to rotate upward along the first external thread on the joystick body 4 to wrap the trachea body 2 around the outside of the joystick body 4. This can avoid the operating handle 1 from being rotated too many times when screwed in for installation, causing the trachea body 2 to be wrapped too tightly and the trachea body 2 to be pulled out of the operating handle 1.

[0049] It should be noted that the air pressure of the compressed air in the truck is between 8 and 12 atmospheres. Therefore, the pipeline that can withstand this pressure is very tough and basically inextensible in the length direction, and can effectively transmit torque. That is, when the operating handle 1 rotates during the threaded connection process, the operating handle 1 can drive the plug-in fixed end of the trachea body 2 to move around the operating handle 1, driving the connecting sleeve 5 to move.

[0050] It should be noted that, in this embodiment, the tube clamp 3 and the screw 6 serve as fixing structures, and their function is to fix a small section of the tracheal body 2 on the connecting sleeve 5, so that when the operating handle 1 is screwed into the joystick body 4, the torque of the operating handle 1 can be transmitted to the connecting sleeve 5 through the tracheal body 2. Therefore, it can be understood that other fixing structures that can achieve such functions can be used in this embodiment, and those skilled in the art can adaptively adjust the size, shape and composition of the fixing structure according to the usage scenario and test conditions.

[0051] It should be noted that the blind hole in the connecting sleeve 5, which is compatible with the screw 6, is deep enough to ensure a safe distance from the internal threaded portion. Since the common specifications of the joystick body 4 range from Φ20 to Φ30, the wall thickness of the connecting sleeve 5 needs to ensure sufficient depth of the blind hole. Therefore, the connecting sleeve 5 cannot directly use a standard nut. The connecting sleeve 5 must adopt a non-standard shape, such as half hexagonal and half rectangular. The axis of the blind hole is also offset from the center of the connecting sleeve 5 to facilitate the installation of the pipe clamp 3. The pipe clamp 3 can accommodate two to three trachea bodies 2.

[0052] It should be noted that the joystick body 4 is provided with a first external thread that is compatible with the connecting sleeve 5, and the joystick body 4 is provided with a second external thread that is compatible with the operating handle 1. The first external thread and the second external thread are in opposite directions. In specific use, the first external thread is a right-handed external thread for installing the connecting sleeve 5 because the second external thread of the existing joystick body 4 for installing the operating handle 1 is a left-handed external thread. In addition, the joystick body 4 can be provided with a first undercut 41 and a second undercut 42. The provision of the first undercut 41 and the second undercut 42 facilitates the processing of the first external thread on the joystick body 4. The reason why the first external thread is a left-handed external thread opposite to the second external thread is that the left-handed thread allows the connecting sleeve 5, which is driven by the tracheal body 2, to rotate and rise, reducing the distance between the connecting sleeve 5 and the operating handle 1. If a conventional right-handed thread is used, the connecting sleeve 5 will move downward, and the distance between the connecting sleeve 5 and the operating handle 1 will increase, which may cause the tracheal body 2 to be pulled out of the operating handle 1, posing a risk.

[0053] It should be noted that, as an option, the connecting sleeve 5 can be made of plastic to reduce weight. Specifically, the connecting sleeve 5 can be made of nylon or polyoxymethylene due to their self-lubricating properties. This material selection reduces tightening torque, making it easier for the connecting sleeve 5 to be pulled by the tracheal body 2 and rotated. The threads required for the screws 6 securing the pipe clamp 3 can be pre-machined on the connecting sleeve 5, or self-tapping screws can be used.

[0054] In some alternative embodiments: See Figure 1 and Figure 2 As shown, the embodiment of the present application provides a manual transmission joystick air supply pipeline installation structure, wherein the joystick body 4 and the connecting sleeve 5 of the manual transmission joystick air supply pipeline installation structure are slidably connected, and a sliding mechanism is provided between the joystick body 4 and the connecting sleeve 5 to enable the connecting sleeve 5 to slide axially along the joystick body 4;

[0055] The sliding mechanism includes a sliding groove opened along the axial direction of the operating rod body 4 and a sliding rod which is threadedly connected to the inner portion of the connecting sleeve 5 and has one end extending into the interior of the sliding groove.

[0056] The joystick body 4 and the connecting sleeve 5 of the manual transmission joystick air supply pipe mounting structure of the embodiment of the present application are slidably connected, and a sliding mechanism is provided between the joystick body 4 and the connecting sleeve 5 to enable the connecting sleeve 5 to slide axially along the joystick body 4. The sliding mechanism includes a sliding groove opened along the axial direction of the joystick body 4 and a sliding rod which is threadedly connected to the internal thread of the connecting sleeve 5 and has one end extending into the interior of the sliding groove.

[0057] When in use, the connecting sleeve 5 is put on the joystick body 4, the sliding rod is screwed into the connecting sleeve 5, the sliding rod extends into the slide groove on the joystick body 4, the trachea body 2 passes through the pipe clamp 3, and the screw 6 is screwed into the blind hole on the connecting sleeve 5. The screw 6 is installed through the pipe clamp 3. After the screw 6 is screwed into place, the pipe clamp 3 clamps and positions the trachea body 2, and then the trachea body 2 is inserted into the operating handle 1, and the operating handle 1 is screwed in along the second external thread on the joystick body 4. The operating handle 1 drives the plug-in fixed end of the trachea body 2 to move circumferentially around the operating handle 1, and the trachea body 2 drives the connecting sleeve 5 to slide upward along the axial direction of the joystick body 4 to wrap the trachea body 2 around the outside of the joystick body 4.

[0058] It should be noted that the sliding mechanism in this embodiment is not drawn in the figure. Its function is to enable the connecting sleeve 5 to have the freedom to slide axially along the joystick body 4, while limiting the rotation of the connecting sleeve 5 around the joystick body 4. When the winding length between the connecting sleeve 5 and the operating handle 1 is insufficient, the connecting sleeve 5 can move upward to compensate, so as to prevent the trachea body 2 from being wound too tightly and pulling the trachea body 2 out of the operating handle 1. Therefore, it can be understood that other sliding mechanisms that can achieve such functions can be used in this embodiment, and those skilled in the art can adaptively adjust the size, shape and structure of the sliding mechanism according to the usage scenario and test conditions.

[0059] In some alternative embodiments: See Figure 1 and Figure 2 As shown, an embodiment of the present application provides a manual transmission joystick air supply pipeline installation structure, in which the joystick body 4 of the manual transmission joystick air supply pipeline installation structure is fixedly connected to the connecting sleeve 5.

[0060] The joystick body 4 of the manual transmission joystick air supply pipe mounting structure of the embodiment of the present application is fixedly connected to the connecting sleeve 5, and the connecting sleeve 5 is fixedly connected to the joystick body 4, so that the trachea body 2 passes through the pipe clamp 3, and the screw 6 is screwed into the blind hole on the connecting sleeve 5. The screw 6 passes through the pipe clamp 3 for installation. After the screw 6 is screwed into place, the pipe clamp 3 clamps and positions the trachea body 2, and then the trachea body 2 is inserted into the operating handle 1, and the operating handle 1 is screwed in along the second external thread on the joystick body 4. The operating handle 1 drives the plug-in fixed end of the trachea body 2 to move circumferentially around the operating handle 1 to wrap the trachea body 2 around the outside of the joystick body 4.

[0061] It should be noted that the joystick body 4 of the embodiment of the application is fixedly connected to the connecting sleeve 5. When the operating handle 1 is screwed in along the second external thread on the joystick body 4, the operating handle 1 drives the plug-in fixed end of the tracheal body 2 to move circumferentially around the operating handle 1, thereby wrapping the tracheal body 2 around the outside of the joystick body 4. During the screwing-in process of the operating handle 1, the operating handle 1 will move downward. When the wrapping length between the connecting sleeve 5 and the operating handle 1 is insufficient, the downward movement of the operating handle 1 can compensate, preventing the tracheal body 2 from being pulled out of the operating handle 1 due to excessive wrapping. Therefore, when the connecting sleeve 5 is properly fixed and installed, there is no need for the connecting sleeve 5 to move upward to compensate.

[0062] In some alternative embodiments: See Figure 1 and Figure 2 As shown, an embodiment of the present application provides a manual transmission joystick air supply pipeline installation structure, which also includes a shield covering the outer periphery of the joystick body 4 and the trachea body 2, and the upper end of the shield abuts against the operating handle 1, and the operating handle 1 is provided with an trachea connector for plugging into the trachea body 2.

[0063] The manual transmission joystick air supply pipe installation structure of the embodiment of the present application also includes a protective cover covering the outer periphery of the joystick body 4 and the trachea body 2, the upper end of the protective cover abuts against the operating handle 1, and the operating handle 1 is provided with an trachea connector for plugging into the trachea body 2. During specific use, the protective cover is used to cover the outer periphery of the joystick body 4 and the trachea body 2, and the trachea connector facilitates plugging into the trachea body 2.

[0064] It should be noted that the lower end of the shield is clamped on the decorative base, and the trachea body 2 extends from the upper end of the shield. Before the operating handle 1 rotates to drive the trachea body 2 to move and wrap around, the shield is wrapped around the outer periphery of the joystick body 4 and the trachea body 2.

[0065] See also Figure 1 and Figure 2 As shown, a second aspect of the embodiment of the present application provides a method for installing a manual transmission joystick air supply pipeline. The method uses the manual transmission joystick air supply pipeline installation structure of any of the above embodiments, and the method includes the following steps:

[0066] Install the connecting sleeve 5 on the joystick body 4;

[0067] Install the pipe clamp 3 on the connecting sleeve 5 to fix the trachea body 2;

[0068] Connect the trachea body 2 to the operating handle 1;

[0069] An operating handle 1 is installed on the joystick body 4 , and the operating handle 1 drives the trachea body 2 to wrap around the outer side of the joystick body 4 .

[0070] The method for installing the manual transmission joystick air supply pipeline of the embodiment of the present application includes the following steps:

[0071] S1. Install the connecting sleeve 5 on the joystick body 4;

[0072] S2. Install the pipe clamp 3 on the connecting sleeve 5 to fix the trachea body 2;

[0073] S3. Connect the trachea body 2 to the operating handle 1;

[0074] S4. Install the operating handle 1 on the joystick body 4. The operating handle 1 drives the trachea body 2 to wrap around the outside of the joystick body 4.

[0075] It should be noted that the trachea body 2 is plugged into the operating handle 1, and the joystick body 4 is installed on the operating handle 1 by means of a threaded connection. The joystick body 4 can drive the upper end of the trachea body 2 to move during the screwing-in installation process, so that the trachea body 2 is wrapped around the outer side of the joystick body 4, avoiding the formation of a bulge and lifting the shield, thereby not affecting the appearance of the shield, thereby ensuring the quality of interior assembly. Therefore, in the specific operation process, when steps S3 and S4 are actually performed in this embodiment, the operating handle 1 can be screwed into the second external thread on the joystick body 4, and the screw thread is not tightened first. Tighten the operating handle 1, reserve three to four turns of thread below the operating handle 1, then plug the trachea body 2 into the trachea connector on the operating handle 1, and then tighten the operating handle 1 into place. The operating handle 1 drives the plug-in fixed end of the trachea body 2 to move circumferentially around the operating handle 1, and the trachea body 2 drives the connecting sleeve 5 to rotate upward along the first external thread on the joystick body 4 to wrap the trachea body 2 around the outside of the joystick body 4. This can avoid the operating handle 1 being rotated too many times when it is screwed in for installation, causing the trachea body 2 to be too tightly wound and the trachea body 2 to be pulled out of the operating handle 1.

[0076] In some alternative embodiments: See Figure 1 and Figure 2 As shown, an embodiment of the present application provides a method for installing a manual transmission joystick air supply pipeline. The manual transmission joystick air supply pipeline installation method includes installing an operating handle 1 on the joystick body 4, and the operating handle 1 drives the air pipe body 2 to wrap around the outside of the joystick body 4. The method specifically includes the following steps:

[0077] The operating handle 1 is screwed into the second external thread on the joystick body 4, and the operating handle 1 drives the trachea body 2 to move. The trachea body 2 drives the connecting sleeve 5 to rotate upward along the first external thread on the joystick body 4 to wrap the trachea body 2 around the outside of the joystick body 4.

[0078] The method for installing the manual transmission joystick air supply pipeline in the embodiment of the present application specifically includes the following steps:

[0079] S1. The control mechanism assembly of the integrated joystick body 4 is installed on the floor of the cab;

[0080] S2. The trachea body 2 is extended along the joystick body 4. The connecting sleeve 5 is inserted from the top of the joystick body 4 and screwed onto the first external thread on the joystick body 4. It does not need to be tightened. A section of thread is left above the connecting sleeve 5. Since the connecting sleeve 5 does not need to be tightened, the problem of not being able to use a standard wrench due to the shape of the connecting sleeve 5 does not affect the assembly. The connecting sleeve 5 can be screwed in manually. It should be noted that the first external thread is set in the middle position of the joystick body 4 or below the middle position to ensure that the joystick body 4 between the operating handle 1 and the connecting sleeve 5 can wrap around the trachea body 2 of sufficient length;

[0081] S3. Fix the trachea body 2 to the connecting sleeve 5 with the pipe clamp 3 without using a cable tie;

[0082] S4. Install the plastic decorative base on the cab floor;

[0083] S5. Install the shield, snap the lower end of the shield onto the decorative base, and extend the trachea body 2 from the upper end of the shield;

[0084] S6. Install the operating handle 1 onto the joystick body 4, then connect the air pipe body 2 to the operating handle 1. If the air pipe is too long, shorten it.

[0085] It should be noted that when tightening the operating handle 1 to the top thread of the joystick body 4 in the above step S6, do not tighten it all at first. When there are three to four turns of thread left at the end of the thread, insert the trachea body 2 into the operating handle 1, and then tighten the operating handle 1 into place. At this time, the upper end of the trachea body 2 rotates with the operating handle 1, and the middle part of the trachea body 2 is fixed on the connecting sleeve 5. The relative movement will generate a tightening torque, driving the connecting sleeve 5 to rotate and rise along the joystick body 4. As the connecting sleeve 5 rises, the trachea body 2 is wrapped around the joystick body 4, and its shape changes from a straight line to a spiral, thereby absorbing the excess length and causing the trachea body 2 to automatically retract into the shield to prevent the trachea body 2 from being exposed or propping up the shield. At this time, the pipeline below the connecting sleeve 5 will also become spiral, so sufficient pipeline length must be reserved before assembly.

[0086] It should be noted that to facilitate assembly and reduce on-site assembly workload, the length of the tracheal body 2 should be fixed. Optionally, to facilitate identification during assembly and improve work efficiency, the length of the tracheal body 2 can be fixed for a specific vehicle model. Two markings can also be made on the tracheal body 2: one at the fixing point of the connecting sleeve 5, and one at the last fixing point of the tracheal body 2 on the floor, inside the hard decorative base at the lower end of the joystick body 4.
