[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] like Figure 1 and Figure 2 As shown, this application discloses a vehicle, which includes a driver's cab, a control unit 1, a flexible shaft structure 2, a sealing gasket 3, and a bracket 4.

[0042] Specifically, the cab may include the vehicle body floor 5. It is understood that the vehicle body floor 5, together with other components of the vehicle, forms the cab.

[0043] The control unit 1 is mounted on the vehicle floor 5 of the driver's cab, and is located above the vehicle floor 5 (i.e., the control unit 1 is located inside the driver's cab). The control unit 1 is mainly used to control the transmission of the vehicle to change gears so that the vehicle can travel in the appropriate gear. The control unit 1 may include a control knob 11, a control cover 12, a control unit body 13, and a control unit fixing member 14. The control knob 11 is connected to the control unit body 13, the control unit body 13 is connected to the control unit fixing member 14, and the control cover 12 is fitted over the outside of the control unit body 13 to protect the control unit body 13.

[0044] like Figure 4As shown, the flexible shaft structure 2 may include a connecting flexible shaft and a tube sleeved on the outside of the connecting flexible shaft. The connecting flexible shaft may include a gear selection flexible shaft and a gear shifting flexible shaft, which can respectively realize the gear selection and gear shifting of the vehicle. Therefore, the flexible shaft structure 2 may include a first tube 21 and a second tube 22, wherein the first tube 21 is sleeved on the outside of the gear selection flexible shaft, and the second tube 22 is sleeved on the outside of the gear shifting flexible shaft. In other words, the gear selection flexible shaft is located inside the first tube 21, and the gear shifting flexible shaft is located inside the second tube 22. The first tube 21 and the second tube 22 can respectively protect the gear selection flexible shaft and the gear shifting flexible shaft.

[0045] Meanwhile, the upper end of the flexible shaft structure 2 is connected to the control body 13 in the control unit 1, and the lower end of the flexible shaft structure 2 passes through the through hole 51 on the vehicle floor 5 and is connected to the vehicle's transmission, thereby realizing the connection between the control unit 13 and the transmission. In this way, when the control unit 13 shifts gears, the transmission can be controlled by the flexible shaft.

[0046] It is understandable that the transmission is located below the vehicle floor 5 in the driver's cab, meaning that the transmission itself is not located within the driver's cab space.

[0047] like Figure 3 As shown, the sealing gasket 3 is fitted onto the flexible shaft structure 2, and the sealing gasket 3 is sealed to the vehicle floor 5 at the through hole 51. The sealing gasket 3 is tightly fitted onto the flexible shaft structure 2 to fill the gap between the flexible shaft structure 2 and the through hole 51, thereby preventing dust, moisture, mud, and other impurities from entering the cab from outside the vehicle through the through hole 51. At the same time, the installation of the sealing gasket 3 can also reduce the noise entering the cab from below the cab (engine compartment), thereby improving the comfort of the driver. In this embodiment, the sealing gasket 3 is fitted onto both the first tube 21 and the second tube 22 of the flexible shaft structure 2. In terms of sealing performance, a single sealing gasket 3 can form a more continuous and complete sealing interface at the through hole 51, greatly reducing potential leakage paths, thereby ensuring a higher level of sealing performance at the sealing gasket 3 location.

[0048] Furthermore, during installation, only one sealing gasket 3 needs to be connected and adjusted. This not only significantly simplifies the installation process and reduces installation difficulty, but also significantly improves installation efficiency, effectively saving manpower and time costs. At the same time, the integrated sealing gasket 3 design reduces the number of components, which helps to improve the overall stability and reliability of the system.

[0049] like Figure 1 and Figure 2 As shown, bracket 4 is installed on the vehicle floor 5 and is located below the vehicle floor 5.

[0050] Specifically, bracket 4 is located below the vehicle floor 5, meaning it is not located within the driver's cabin. This provides the driver with a more spacious and comfortable operating environment, allowing for greater freedom of movement and reducing fatigue and operational inconvenience caused by cramped space. For example, with more legroom, the driver is not obstructed by bracket 4 when shifting gears or using the pedals, improving accuracy and comfort. Simultaneously, the freed-up space also facilitates the rational layout of other cabin equipment, such as optimizing seat design and adjustment range, allowing the seat to better adapt to different driver body types and driving habits, thus enhancing the overall driving experience.

[0051] The space beneath the cab floor 5 provides a relatively independent and spacious installation area for the bracket 4, which facilitates the layout and integration of the transmission control system with other chassis components. This allows for more rational planning of the routing of flexible shafts, pipes, and wiring, avoiding interference with other components within the cab and resulting in a more compact and orderly chassis system layout. This optimized layout not only improves space utilization but also facilitates system assembly and maintenance, reduces production and repair costs, and enhances the overall performance and reliability of the vehicle.

[0052] Meanwhile, in this embodiment, the bracket 4 may include a connecting plate 41, on which a plurality of screws 42 are provided. The connecting plate 41 is fixedly mounted on the vehicle floor 5 by the plurality of screws 42. This connection method ensures that the bracket 4 will not be displaced or loosened during vehicle operation. Even under complex road conditions, when the vehicle is subjected to vibration, bumps and various external forces, the bracket 4 can still maintain its correct position on the vehicle floor 5.

[0053] Specifically, such as Figure 3 As shown, the side of the connecting plate 41 closest to the vehicle floor 5 is in close contact with the sealing gasket 3. By applying a certain pressure to the sealing gasket 3, the sealing gasket 3 is tightly connected to the vehicle floor 5. When the sealing gasket 3 is subjected to pressure from the connecting plate 41, that is, the sealing gasket 3 is squeezed and sealed between the connecting plate 41 and the vehicle floor 5, so that the sealing gasket 3 can better block the through hole 51, thereby improving the sealing effect of the through hole 51.

[0054] The connecting plate 41 of the bracket 4, working in conjunction with the vehicle floor 5, securely fixes the sealing gasket 3 between them. This fixing method ensures that the sealing gasket 3 remains in the correct position as the flexible shaft passes through the through hole 51 of the vehicle floor 5, and will not shift or fall off due to vibration, bumps, or other external forces during vehicle operation. A stable position of the sealing gasket 3 is crucial for ensuring good sealing performance, effectively preventing impurities from entering the cab through the through hole 51 of the vehicle floor 5, and also reducing noise transmitted into the cab from below.

[0055] In related technologies, the connection method between the sealing gasket 3 and the vehicle floor 5 has a significant impact on the system's sealing performance. If the sealing gasket 3 and the vehicle floor 5 are connected only by screws 42, the screws 42 can only provide a stabilizing force to the sealing gasket 3 in its localized area, allowing it to abut against the vehicle floor 5. However, in areas far from the screws 42, the sealing gasket 3 lacks sufficient support, and over long-term use, it is prone to aging and deformation due to uneven stress, leading to gaps and a decrease in sealing effectiveness.

[0056] Compared to the screw connection 42, this application uses the connecting plate 41 of the bracket 4 to fix the sealing gasket 3. The bracket 4 can apply uniform pressure to the entire part where the sealing gasket 3 abuts against the vehicle floor 5. The principle is that the structural cooperation between the bracket 4 and the vehicle floor 5 forms a stable clamping structure, so that the sealing gasket 3 can maintain a tight abutment state in all positions. This connection method ensures that the sealing performance of the sealing gasket 3 is maintained stably during long-term use, effectively preventing impurities from entering the cab through the through hole 51 of the vehicle floor 5, protecting the relevant components of the transmission control system, and improving the overall reliability of the system; at the same time, it can also reduce the noise transmitted to the cab.

[0057] Compared to directly snapping the sealing gasket 3 into the through hole 51 of the vehicle floor 5, although a certain sealing effect can be achieved during initial installation, the sealing gasket 3 is prone to falling off over time due to aging. The design of the bracket 4 in this embodiment avoids this risk. Through proper cooperation with the sealing gasket 3 and the vehicle floor 5, the bracket 4 provides reliable fixation and support for the sealing gasket 3, making it less prone to falling off due to aging during long-term use. This not only ensures a continuous and stable sealing effect but also reduces system failures caused by impurities entering due to the sealing gasket 3 falling off, extends the service life of the transmission control system, and improves the safety and stability of vehicle operation.

[0058] In one embodiment, such as Figure 4 As shown, the sealing gasket 3 includes a connecting part 31 and a sealing part 32.

[0059] Specifically, the connecting part 31 is sleeved on the flexible shaft structure 2. In this embodiment, since the flexible shaft structure 2 includes a first tube 21 and a second tube 22 that are independent of each other, the connecting part 31 includes two integrally formed connecting sleeves 311, which are respectively sleeved on the first tube 21 and the second tube 22. The two independent connecting sleeves 311 provide independent support structures for the first tube 21 and the second tube 22 of the flexible shaft structure 2. During vehicle operation, the first tube 21 and the second tube 22 may be subjected to forces of different directions and magnitudes. The independent connecting sleeves 311 can cope with these forces respectively, preventing mutual interference or influence between the first tube 21 and the second tube 22.

[0060] Furthermore, the two integrated connecting sleeves 311 are relatively simple and convenient to install. Operators only need to insert the first pipe body 21 and the second pipe body 22 into their respective connecting sleeves 311 to complete the initial installation, without requiring complex adjustments or positioning. During maintenance, if it is necessary to inspect, repair, or replace a particular pipe body or its corresponding connecting sleeve 311, it can be done conveniently and independently without affecting the structural integrity of the other pipe body and the entire connecting part 31.

[0061] In one embodiment, such as Figure 3 As shown, the connecting sleeve 311 is funnel-shaped. This funnel shape provides a guiding function during installation. When installing the sealing gasket 3 onto the bracket 4 and the vehicle floor 5, the larger opening of the funnel shape more easily aligns with the corresponding structure on the bracket 4, guiding the connecting sleeve 311 accurately into the snap-fit ​​position. Operators do not need to perform complex and precise alignment operations; they can simply push it along the inclined surface of the funnel shape to achieve a smooth snap-fit, greatly improving installation efficiency and reducing installation difficulty. Especially on large-scale production lines, this effectively saves assembly time and increases production cycle time.

[0062] After the funnel-shaped connecting sleeve 311 is engaged with the bracket 4, its unique shape provides a more stable connection. When the engagement point is subjected to external forces from various directions, the funnel-shaped structure can distribute the force over a larger area, preventing localized stress concentration that could lead to loosening or detachment at the engagement point. This stable connection ensures that the sealing gasket 3 remains in the correct position during vehicle operation. Even under complex road conditions with strong vibrations and bumps, it effectively prevents the sealing gasket 3 from shifting, thereby maintaining good sealing performance and ensuring the normal operation of the transmission control system.

[0063] In one embodiment, reference is made to... Figure 4 As shown, the sealing part 32 is provided along the circumferential edge of the upper side of the connecting part 31, and the sealing part 32 abuts against the vehicle floor 5 at the edge of the through hole 51.

[0064] Specifically, at the through-hole 51 on the vehicle floor 5, the sealing part 32 abuts tightly against the edge of the vehicle floor 5 at the through-hole 51, forming a continuous sealing interface around the through-hole 51. This design effectively prevents dust, moisture, mud, and other impurities from entering the cab through the through-hole 51 from outside the vehicle, keeping the cab environment clean and dry; at the same time, it can also effectively reduce noise transmitted from below the cab to the cab. Furthermore, the sealing part 32 is made of a flexible material, such as rubber. Thus, during vehicle operation, if the vehicle body undergoes various deformations and vibrations due to road conditions, acceleration, deceleration, etc., the flexible material and reasonable structural design of the sealing part 32 can adapt to these changes, allowing the sealing part 32 to deform to a certain extent with the deformation of the vehicle floor 5, always maintaining good contact with the edge of the through-hole 51 of the vehicle floor 5, ensuring that the sealing effect is not affected.

[0065] In one embodiment, such as Figure 3 As shown, in order to further improve the sealing performance, a groove 321 is provided on the sealing part 32 along the side of the sealing part 32, and the vehicle floor 5 around the through hole 51 is embedded in the groove 321.

[0066] Specifically, the groove 321 is opened circumferentially along the sealing part 32, and the opening of the groove 321 faces away from the sealing part 32 itself. When installing the sealing gasket 3, the vehicle floor 5 around the through hole 51 needs to enter the groove 321. At this time, the hole wall of the through hole 51 abuts against the inner wall of the groove 321, thereby achieving a fixed connection between the vehicle floor 5 and the sealing part 32. This forms an all-round sealing system from the edge of the through hole 51 to the inside, greatly enhancing the integrity of the seal. Even when the vehicle faces complex vibrations, impacts, and temperature changes during operation, it can effectively prevent impurities from entering from all directions of the through hole 51, providing more reliable sealing protection for the cab, ensuring a clean and stable interior environment, and reducing noise transmitted from below the cab to the cab.

[0067] During gear shifting, the flexible shaft structure 2 reciprocates within the through hole 51. The tight contact between the groove 321 and the wall of the through hole 51 provides additional radial support for the flexible shaft, limiting its radial wobble and offset during movement, resulting in smoother and more precise motion. This not only improves the feel and accuracy of gear shifting but also reduces friction between the flexible shaft and the wall of the through hole 51, reducing wear and further extending the service life of the flexible shaft, ensuring the long-term stable operation of the transmission system.

[0068] In one embodiment, such as Figure 5 As shown, the connecting plate 41 has a bracket hole 43.

[0069] Specifically, the connecting part 31 passes through the bracket hole 43, and the connecting plate 41 around the bracket hole 43 abuts against the sealing part 32. During installation, the flexible shaft structure 2 can accurately enter the through hole 51 of the vehicle body floor 5 along the bracket hole 43, avoiding the risk of the flexible shaft structure 2 scratching or colliding with the edge of the through hole 51 of the vehicle body floor 5, ensuring that the flexible shaft structure 2 passes smoothly in the through hole 51, reducing wear on the flexible shaft, ensuring the integrity and performance stability of the flexible shaft structure 2, and thus helping to improve the accuracy and reliability of the gear shifting operation of the transmission control system.

[0070] In one embodiment, such as Figure 4 As shown, the bracket 4 includes a support plate 44 and a snap-fit ​​plate 45. The support plate 44 is located on the side of the connecting plate 41 away from the vehicle floor 5 and extends downward. The snap-fit ​​plate 45 is located at the end of the support plate 44 away from the connecting plate 41 and extends inward in the direction intersecting with the connecting plate 41. A snap-fit ​​groove 46 is provided on the snap-fit ​​plate 45. Meanwhile, the sealing gasket 3 includes a collar 33, which is located at the end of the connecting portion 31 away from the sealing portion 32, and the collar 33 is snapped into the groove 46.

[0071] Specifically, refer to Figure 4 and Figure 5 As shown in this embodiment, the collar 33 is a columnar structure extending axially, and a positioning groove 331 extending radially inward is provided on the outer periphery of the collar 33; simultaneously, the snap-fit ​​plate 45 also includes an installation notch 461 communicating with the snap-fit ​​groove 46, and the positioning groove 331 is positioned and installed in the snap-fit ​​groove 46 of the snap-fit ​​plate 45 via the installation notch 461. In this way, the collar 33 can be installed into the snap-fit ​​groove 46, thereby realizing the connection between the collar 33 and the snap-fit ​​plate 45 (e.g., Figure 2 (As shown).

[0072] Meanwhile, the groove 46 and the positioning groove 331 of the collar 33 are typically fitted with an interference fit. During installation, when the positioning groove 331 of the collar 33 is installed into the groove 46 through the installation notch 461, the size of the groove 46 is slightly smaller than the outer diameter of the positioning groove 331 of the collar 33. This creates pressure between the positioning groove 331 of the collar 33 and the inner wall of the groove 46, resulting in friction. This friction is a crucial force preventing the collar 33 from dislodging from the groove 46. During vehicle operation, even under external forces such as vibration and bumps, as long as the external force does not exceed the limit of friction, the collar 33 can remain stably held within the groove 46, ensuring that the sealing gasket 3 does not lose its sealing function due to accidental dislodgement of the collar 33.

[0073] At the same time, refer to Figure 2 and Figure 4As shown, in one embodiment, a boss 332 is provided on the collar 33 along the outer periphery of the collar 33. The boss 332 extends in a direction away from the collar 33 and abuts against the snap-fit ​​plate 45.

[0074] Specifically, the boss 332 is positioned adjacent to the positioning groove 331 on the collar 33. When the positioning groove 331 of the collar 33 is engaged in the slot 46, the boss 332 will also abut against the snap-fit ​​plate 45 around the slot 46 in the axial direction of the collar 33. This can limit the collar 33 and reduce the impact of the collar 33 on the bracket 4 due to vehicle vibration during vehicle operation, thereby protecting the bracket 4.

[0075] The support plate 44 is located on the side of the connecting plate 41 away from the vehicle floor 5, providing a solid support foundation for the snap-fit ​​plate 45. During the snap-fit ​​process between the collar 33 and the slot 46, the support plate 44, through its own structural strength and its connection with the snap-fit ​​plate 45, ensures that the snap-fit ​​plate 45 maintains a stable position and shape, and will not deform or shift due to external forces. At the same time, the support plate 44 also plays a certain auxiliary positioning role for the collar 33, enabling the collar 33 to enter the correct position more accurately and smoothly when inserted into the slot 46, further improving the reliability and stability of the snap-fit.

[0076] The snap-fit ​​structure composed of the support plate 44 and the snap-fit ​​plate 45 provides stable snap-fit ​​support for the connecting sleeve 311. The support plate 44 increases the overall strength of the snap-fit ​​structure, enabling it to withstand greater external forces without easily deforming or being damaged. The snap groove 46 on the snap-fit ​​plate 45 precisely matches the collar 33, ensuring the accuracy and tightness of the snap-fit. During vehicle operation, even under various complex working conditions such as vibration and bumps, this structure can effectively prevent the collar 33 from accidentally falling off the snap groove 46, ensuring the reliability of the connection between the sealing gasket 3 and the bracket 4, thereby maintaining good sealing performance.

[0077] In one embodiment, reference is made to... Figure 2 and Figure 5 As shown, the connecting plate 41 is fixedly connected to the controller fixing member 14 in the controller 1 by screws 42. That is, the screws 42 also pass through the controller fixing member 14, and a nut is screwed into the screws 42. By using the nut to press against the controller fixing member 14, the controller fixing member 14 and the bracket 4 can be fixed to the vehicle floor 5 at the same time.

[0078] In one embodiment, reference is made to... Figure 5As shown, the connecting plate 41 has at least one recess 411, and the recess 411 extends away from the plane of the connecting plate 41 in a direction away from the vehicle floor 5. The recess 411 can cooperate with some protruding structures on the vehicle floor 5, so that the connecting plate 41 and the vehicle floor 5 can fit more tightly, thereby improving the connection effect between the bracket 4 and the vehicle floor 5.

[0079] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
