Description

Technical Field

[0001] This invention relates to the field of hydraulic tilt control system technology for commercial vehicle cabs, and more specifically, to a hydraulic tilt control system for a cab and a vehicle. Background Technology

[0002] In current technology, both domestic and international medium and heavy-duty flat-nose commercial vehicle cabs utilize hydraulic tilting control systems. These systems can be broadly categorized into two types based on the hydraulic pump configuration: one integrates the manual pump and fuel tank, with the electric pump installed separately; the other integrates the manual pump, electric pump, and fuel tank. Based on placement, they can be categorized as either located near the foot pedal or near the front wheel and rear mudguard. All these solutions share a common problem: the fuel tank is too close to the manual operation area of ​​the pump, frequently leading to fuel contamination due to overfilling or poor sealing, thus causing operational inconvenience.

[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a hydraulic tilting control system for the cab and a vehicle, in order to solve the problem of oil contamination caused by poor sealing due to the integration or close proximity of the manual pump and the oil tank in the hydraulic tilting control system of the cab in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a cab hydraulic tilting control system is provided, comprising: a pump assembly, which integrates a manual pump and an electric pump; an oil reservoir located on one side of the pump assembly, which is connected to the pump assembly via a connecting oil pipe; wherein both the oil reservoir and the pump assembly are located at the first-level foot pedal of the cab; and both the oil reservoir and the pump assembly are connected to the vehicle's foot pedal bracket assembly.

[0006] Furthermore, the oil tank includes: a tank body; an oil inlet located at the top or side wall of the tank body; an oil pipe interface located at the bottom of the tank body, through which the connecting oil pipe is connected to the oil tank; and a fixing seat, of which multiple fixing seats are provided, spaced apart circumferentially along the bottom of the tank body, and the oil tank is detachably connected to the foot pedal bracket assembly via the fixing seats.

[0007] Furthermore, the enclosure includes an upper enclosure and a lower enclosure, which are assembled using a vibration friction welding process, and a sealing structure is provided at the joint surface of the upper enclosure and the lower enclosure.

[0008] Furthermore, the housing is made of translucent nylon material, and the outside of the housing is marked with scale lines to indicate the hydraulic oil level inside the housing.

[0009] Furthermore, the oil inlet protrudes from the surface of the housing and is located inside the window of the pedal decorative cover.

[0010] Furthermore, the interior of the housing is provided with at least one partition, which divides the inner cavity of the housing into multiple independent spaces. The partition is used to suppress the sloshing of hydraulic oil during vehicle operation.

[0011] Furthermore, the oil tank also includes an oil guide pipe, one end of which is connected to the top of the tank body, and the other end of which extends along the side of the tank body. A portion of the oil guide pipe is fixed to the side of the tank body away from the oil filling port by an oil guide pipe clip.

[0012] Furthermore, both the oil reservoir and the pump assembly are located at the front wheel mudguard, and both the oil reservoir and the pump assembly are connected to the mudguard bracket.

[0013] Furthermore, the oil tank includes: a tank body; a fixing seat, the fixing seat being embedded in the side wall of the tank body, and the oil tank being detachably connected to the mudguard bracket through the fixing seat.

[0014] Furthermore, the oil storage tank is cylindrical or cubic in shape.

[0015] According to another aspect of the present invention, a vehicle is provided having a cab hydraulic tilting control system, wherein the cab hydraulic tilting control system is the aforementioned cab hydraulic tilting control system.

[0016] By integrating a manual pump and an electric pump into a pump assembly, and independently placing the oil reservoir on one side of the pump assembly, the two are connected by a connecting oil pipe. Both the oil reservoir and the pump assembly are fixedly mounted on the foot pedal bracket assembly at the first-level foot pedal in the driver's cab. This arrangement effectively prevents oil overflow due to excessive oil filling or poor sealing by separating the oil reservoir and the pump assembly in space, thereby preventing oil contamination of the manual operation parts. It solves the technical problem of inconvenient operation in existing integrated or close-range arrangement schemes, and provides stable and convenient hydraulic tilting control support at the foot pedal.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0036] Combination Figures 1 to 6 As shown, according to a specific embodiment of this application, a cab hydraulic tilting control system is provided.

[0037] Specifically, such as Figure 1 As shown, the cab hydraulic tilting control system includes: a pump assembly 2, which is an integrated set of a manual pump and an electric pump; an oil reservoir 1, which is located on one side of the pump assembly 2, and the oil reservoir 1 and the pump assembly 2 are connected by a connecting oil pipe 3; wherein, the oil reservoir 1 and the pump assembly 2 are both located at the first foot pedal of the cab; the oil reservoir 1 and the pump assembly 2 are both connected to the vehicle's foot pedal bracket assembly 4.

[0038] Pump assembly 2 is not a single-function pump body, but a composite assembly integrating a manual pump unit and an electric pump unit. In this embodiment, pump assembly 2 is bolted to the foot pedal bracket assembly 4 at the first-level foot pedal in the cab. Its position is adjacent to the oil tank 1 but remains independent, together forming the core power execution part of the cab tilt control.

[0039] By integrating a manual pump and an electric pump into a pump assembly, and independently placing the oil reservoir on one side of the pump assembly, the two are connected by a connecting oil pipe. Both the oil reservoir and the pump assembly are fixedly mounted on the foot pedal bracket assembly at the first-level foot pedal in the driver's cab. This arrangement effectively prevents oil overflow due to excessive oil filling or poor sealing by separating the oil reservoir and the pump assembly in space, thereby preventing oil contamination of the manual operation parts. It solves the technical problem of inconvenient operation in existing integrated or close-range arrangement schemes, and provides stable and convenient hydraulic tilting control support at the foot pedal.

[0040] Specifically, such as Figure 2 As shown, the oil tank 1 includes: a tank body 11; an oil inlet 12, which is located on the top or side wall of the tank body 11; an oil pipe interface 15, which is located at the bottom of the tank body 11, and the connecting oil pipe 3 is connected to the oil tank 1 through the oil pipe interface 15; and a fixing seat 14, which is provided in multiples and is arranged circumferentially along the bottom of the tank body 11. The oil tank 1 is detachably connected to the foot pedal bracket assembly 4 through the fixing seat 14.

[0041] Optionally, the overall shape of the housing 11 adopts a partially recessed structure. This recessed design is specifically designed to avoid the foot pedal bracket assembly 4, in order to solve the problem of limited layout caused by irregular available space.

[0042] The fuel tank 1 is connected to the foot pedal bracket assembly 4 via a mounting base 14 at its bottom; the pump assembly 2 is also connected to the same foot pedal bracket assembly 4 via bolts. This shared bracket assembly installation method achieves a stable integration of the system in the cab foot pedal area.

[0043] In this embodiment, three mounting brackets 14 are provided, which are spaced circumferentially along the bottom of the housing 11 to provide stable support. Each mounting bracket 14 has a through hole. The fuel tank 1 is detachably connected to the vehicle's foot pedal bracket assembly 4 via these mounting brackets 14 using bolts and nuts as fasteners. This multi-point circumferentially distributed fixing method ensures the installation stability of the fuel tank at the driver's cab foot pedal.

[0044] The oil pipe interface 15 is located at the bottom of the housing 11 and is the outlet for connecting the oil reservoir 1 to the external hydraulic pipeline. One end of the connecting oil pipe 3 is connected to the oil pipe interface 15, thereby realizing the hydraulic oil circuit connection between the oil reservoir 1 and the pump assembly 2.

[0045] Specifically, the housing 11 includes an upper housing and a lower housing, which are assembled using a vibration friction welding process, and a sealing structure is provided at the joint surface of the upper housing and the lower housing.

[0046] Vibration friction welding: This process generates frictional heat through relative vibration, melting the contact surfaces and fusing them under pressure to ultimately combine the upper and lower parts into a complete, sealed tank structure. This process not only ensures the oil tank has sufficient mechanical strength under vehicle vibration, hydraulic system operating pressure, and its own weight, preventing cracking or deformation, but also guarantees high sealing at the tank joints, effectively preventing hydraulic oil leakage from the joint surface between the upper and lower tanks. This meets the reliability and safety requirements of the commercial vehicle cab tilting control system for hydraulic components.

[0047] A sealing structure is provided at the joint surface of the upper and lower housings. This sealing structure further enhances the leakage prevention capability of the housing and ensures the safety of hydraulic oil during storage and transportation.

[0048] Specifically, the housing 11 is made of translucent nylon material, and the outer side of the housing 11 is provided with scale lines 16, which are used to indicate the hydraulic oil level inside the housing 11.

[0049] The tank body 11 is made of semi-transparent, wear-resistant nylon material. This material choice not only achieves a lightweight structure for the oil tank but also gives the tank body excellent wear resistance to cope with potential friction during vehicle operation. Because the tank body 11 is made of semi-transparent material, users can directly observe the state and level changes of the internal hydraulic oil through the tank wall without opening the tank.

[0050] A scale line 16 is provided on the outer surface of the housing 11. The scale line 16 is arranged in a position on the surface of the housing 11 for easy observation. Its specific function is to provide users with a visual liquid level reference. By directly reading the scale line 16, users can accurately determine the liquid level of the hydraulic oil inside the housing 11, thereby facilitating the monitoring of the oil quantity and timely replenishment, and improving the convenience of maintenance.

[0051] Specifically, such as Figure 2 As shown, the oil filler port 12 protrudes from the surface of the housing 11 and is located inside the window of the pedal decorative cover 5. The oil filler port 12 is located at the top of the housing 11 and features a long-neck design. This long-neck structure allows the oil filler port 12 to extend a certain distance from the top of the housing and is located inside the window of the pedal decorative cover 5, making it directly visible from the window. This design allows users to directly add hydraulic oil through the window, solving the problem of having to flip the cab to add oil in previous foot pedal placement designs.

[0052] Specifically, the housing 11 has at least one partition 17 inside, which divides the inner cavity of the housing 11 into multiple independent spaces. The partition 17 is used to suppress the sloshing of hydraulic oil during vehicle operation.

[0053] During vehicle operation, the hydraulic oil stored in the housing 11 may slosh due to road bumps or the inertial force generated by vehicle acceleration and deceleration. The presence of the internal baffle 17 effectively restricts the flow range of the hydraulic oil, thereby suppressing violent sloshing of the oil inside the housing. This suppression of sloshing brings two main technical effects: first, it reduces the impact force of the oil on the inner wall and structure of the housing 11, reducing structural stress caused by oil impact; second, it significantly reduces the noise generated by oil sloshing and impact on the housing wall, improving the quietness inside or near the cab.

[0054] Optionally, the two ends of the partition 17 are in contact with the inner wall of the box 11, the partition 17 is provided along the length or width of the box 11, and the height of the partition 17 is smaller than the height of the inner cavity of the box 11.

[0055] In terms of arrangement, the partition 17 extends along the length or width of the tank 11. The specific extension direction can be selected according to the length-to-width ratio of the actual oil tank 1 and the anti-sloshing requirements, so as to effectively suppress oil sloshing.

[0056] In terms of height, the height of the baffle 17 is less than the inner cavity height of the housing 11. This means that the baffle 17 does not completely enclose the top space of the housing 11, but exists as a "T" or "L" shaped partition. This non-completely enclosed structural design allows the oil on both sides of the baffle 17 to remain connected above the liquid surface, allowing gas to exchange through the space above the liquid surface. This avoids the formation of a vacuum or high-pressure dead zone below the baffle, ensuring the smooth oil suction of the hydraulic system. At the same time, due to the height limitation of the baffle 17, when the vehicle shakes during operation, the oil can flow and redistribute to a certain extent over the top of the baffle. This helps to balance the oil height on both sides of the baffle, preventing the pump assembly 2 from sucking in air due to excessively low oil level on one side. At the same time, the baffle's blocking effect limits the large lateral swaying amplitude of the oil, thereby reducing the impact force on the housing wall and the noise generated.

[0057] Specifically, the oil storage tank 1 also includes an oil guide pipe 13, one end of which is connected to the top of the tank body 11, and the other end of which extends along the side of the tank body 11. A portion of the oil guide pipe 13 is fixed to the side of the tank body 11 away from the oil inlet 12 by an oil guide pipe clip 6.

[0058] One end of the oil guide pipe 13 is connected to the top of the housing 11, used to lead out the hydraulic oil inside the housing 11 and establish a hydraulic connection with the pump assembly 2. The other end of the oil guide pipe 13 extends along the side of the housing 11. In terms of fixing method, a section of the oil guide pipe 13 is fixedly installed on the side of the housing 11 by the oil guide pipe clip 6. Specifically, the oil guide pipe clip 6 fixes the oil guide pipe 13 to the housing 11, and the fixing position is deliberately arranged on the side away from the oil inlet 12. This arrangement has important functional significance: during vehicle operation, especially when passing through bumpy roads or performing emergency braking or acceleration, the entire vehicle will generate severe vibrations and inertial forces. At this time, the hydraulic oil in the reservoir 1 will shake violently. When the oil level fluctuates or even briefly overflows the filler port during operation, the overflowing oil or oil vapor is confined to the side of the tank or near the filler pipe because the oil guide pipe 13 is located far from the filler port and the pump assembly operating handle. This prevents the oil from splashing or seeping directly into the manual handle (manual pump operating area). This design aims to solve the problem of contamination of the operating area caused by the close proximity of the oil tank and the manual pump in previous designs, thus ensuring the cleanliness and ease of operation of the manual pump operating area.

[0059] Specifically, such as Figure 4 , Figure 5 As shown, both the oil reservoir 1 and the pump assembly 2 are located at the front wheel mudguard, and both the oil reservoir 1 and the pump assembly 2 are connected to the mudguard bracket 7.

[0060] In this embodiment, the layout of the core components of the commercial vehicle cab tilt control system has changed significantly. Specifically, the fuel tank 1 and the pump assembly 2 are both located at the front wheel mudguard bracket 7 of the vehicle, rather than at the footrest.

[0061] The fuel tank 1 is directly mounted and fixed to the mudguard bracket 7 using fasteners (such as bolts), achieving a rigid connection with the vehicle body structure. Similarly, the electric pump assembly 2 is also fixed to the same mudguard bracket 7 using bolts and other connecting components. This arrangement allows the fuel tank 1 and the pump assembly 2 to share the same support structure, namely the mudguard bracket 7.

[0062] Specifically, such as Figure 6 As shown, the oil tank 1 includes: a tank body 11; a fixing seat 14, which is embedded in the side wall of the tank body 11, and the oil tank 1 is detachably connected to the mudguard bracket 7 through the fixing seat 14.

[0063] The fuel tank 1 is detachably connected to the mudguard bracket 7 via the threaded mounting base 14. Specifically, after the bolt passes through the through hole on the mudguard bracket 7, it is directly screwed into the internal thread of the mounting base 14 on the side wall of the tank body 11, thereby firmly fixing the fuel tank 1 to the bracket. Since the mounting base 14 is embedded in the side wall of the tank body, it avoids the extra protruding space required by traditional external mounting bases, making the overall structure more compact. This design "reduces the space required for installation" and is particularly suitable for situations where the space at the front wheel mudguard is limited. The lateral direct bolt connection makes the assembly direction perpendicular to the bracket surface, making the operation more intuitive and convenient, and improving assembly efficiency. Although the mounting base is embedded, the stability of the fuel tank 1 under vehicle driving vibration environment can still be ensured by bolt tightening, preventing the connection from loosening due to shaking.

[0064] In this embodiment, the oil tank 1 still includes an oil inlet 12, which is located at the top or side wall of the tank body 11; an oil pipe interface 15, which is located at the bottom of the tank body 11, and an oil pipe 3 is connected to the oil tank 1 through the oil pipe interface 15; and an oil guide pipe 13, one end of which is connected to the top of the tank body 11, and the other end of which extends along the side of the tank body 11, and part of the oil guide pipe 13 is fixed to the side of the tank body 11 away from the oil inlet 12 by an oil guide pipe clip 6.

[0065] Specifically, the oil tank 1 is cylindrical or cubic in shape. Both achieve the core invention objective of independently arranging the oil tank and avoiding contamination, but adapt to the arrangement constraints of different positions in the vehicle through different geometric shapes.

[0066] In one specific embodiment, the tank 11 presents a standard cylindrical geometry. This shape is designed to meet the needs of specific installation spaces, particularly at the front wheel fender bracket 7, where the space is often irregular or restricted. This allows for a further reduction in the required layout space for the oil tank 1 without changing the oil storage capacity. Compared to a cuboid, a cylindrical shape can more effectively utilize volume and reduce wasted space in certain restricted curved or narrow spaces (such as behind the fender).

[0067] In another specific embodiment, the overall shape of the fuel tank 1's body 11 adopts a polyhedral structure with localized recesses. Its basic geometry can be considered as a cube or cuboid modified with localized features. The main body of the body 11 is a regular cube or cuboid structure, facilitating layout on flat or regular mounting surfaces. When the fuel tank is positioned at the first-level foot pedal in the driver's cab, the foot pedal bracket has a specific geometric shape and protruding parts. The cube body combined with the localized recesses allows the fuel tank to closely fit the irregular contour of the foot pedal bracket, solving the "layout limitation problem caused by irregular usable space" and achieving efficient space utilization. Compared to completely free curved surfaces or cylinders, the cube / cube-based design is easier to achieve through injection molding or welding processes.

[0068] According to another aspect of the present invention, a vehicle is provided having a cab hydraulic tilting control system, wherein the cab hydraulic tilting control system is the aforementioned cab hydraulic tilting control system.

[0069] In a vehicle, the cab hydraulic tilting control system mainly consists of three parts: an independent oil reservoir, an integrated pump assembly, and connecting oil pipes. Unlike existing technologies that separate or fully integrate the manual and electric pumps, this invention integrates the manual and electric pumps into the same assembly. This integration not only reduces the number of parts and assembly complexity but also makes the pump assembly more compact, facilitating modular installation in different locations on the vehicle (such as the footrest or mudguard). The oil reservoir and pump assembly are physically separated but hydraulically connected via connecting oil pipes. This design breaks the limitation of the traditional solution where the oil reservoir is located adjacent to the manual pump operating handle, fundamentally solving the problem of oil contamination of the manual operating parts due to oil spillage or poor sealing of the oil reservoir.

[0070] Depending on the specific vehicle model structure (such as medium and heavy-duty flat-nose commercial vehicles), the layout of this control system on the vehicle is highly flexible, mainly reflected in the following two typical embodiments:

[0071] Example 1: Located at the first-level foot pedal in the cab: The fuel tank and hand pump assembly are both fixed to the first-level foot pedal bracket assembly in the cab. The fuel tank adopts a partially recessed box structure, specifically avoiding the protruding part of the foot pedal bracket, solving the placement problem in irregular spaces. The fuel tank has a long-neck oil inlet that extends to the window of the foot pedal decorative cover. The driver or maintenance personnel can directly add hydraulic oil to the fuel tank through the decorative cover window without tilting the cab, greatly improving maintenance convenience. The oil guide pipe is arranged along the side of the tank and away from the oil inlet, ensuring that when the oil level fluctuates or even briefly overflows during operation, the overflowing oil will not flow to the manual pump handle of the pump assembly, keeping the operating area clean.

[0072] Example 2: Located at the front wheel rear fender: The fuel tank and hand pump assembly are both fixed to the front wheel fender bracket. The fuel tank has a cylindrical shape, which can adapt to the relatively narrow or curved space behind the fender, minimizing the space occupied while maintaining the same fuel storage capacity. The side of the fuel tank has a threaded mounting bracket, which is directly connected to the fender bracket by bolts, simplifying the installation steps and improving assembly efficiency.

[0073] The technical solution of this embodiment has the following beneficial effects:

[0074] 1. Effectively avoids oil contamination and improves operational convenience: This invention fundamentally solves the problem of oil overflow and contamination of the manual operation parts caused by excessive oil filling or poor sealing when the oil tank is too close to the manual pump operation part in traditional integrated solutions, by arranging the pump assembly (manual pump and electric pump) and the oil tank independently and setting a specific distance.

[0075] 2. Flexible layout, strong adaptability, and breakthrough in space limitations: Since the oil reservoir is independent of the pump assembly, this invention is no longer limited by the fixed shape and position of the integrated "pump-reservoir". Users can flexibly choose the installation position of the oil reservoir according to the actual layout conditions of the vehicle (such as the footrest or front wheel mudguard). At the same time, the shape of the oil reservoir (such as cylindrical, concave cube, etc.) can be freely transformed according to the geometric characteristics of the installation space, greatly reducing the space limitations of the layout and improving the freedom of the overall vehicle layout.

[0076] 3. Convenient refueling without tilting the cab: This invention features a specially structured oil inlet (such as a long-neck inlet) on the oil tank, combined with the vehicle body structure (such as the pedal decorative cover window), allowing drivers or maintenance personnel to directly replenish hydraulic oil from the outside without tilting the cab. This significantly simplifies daily maintenance and oil replenishment processes, improving user experience and maintenance efficiency.

[0077] 4. Suppressing oil sloshing, reducing noise and impact, and improving NV performance: The oil tank is equipped with an internal partition 17, dividing the inner cavity into multiple independent spaces. This structure effectively suppresses large-scale hydraulic oil sloshing during vehicle operation, thereby reducing the impact force of the oil on the inner wall of the tank and reducing the risk of tank fatigue. At the same time, the reduction in sloshing amplitude significantly reduces the noise generated by the oil hitting the tank wall, improving the overall vehicle quietness (NV performance).

[0078] 5. Lightweight and visually appealing design for easy status monitoring: The oil tank is made of semi-transparent, wear-resistant nylon material, achieving a lighter weight compared to traditional metal tanks, which helps reduce overall vehicle energy consumption. Furthermore, the tank surface features 16 graduated lines, and combined with the semi-transparent material, allows users to visually and accurately observe the hydraulic oil level and fill volume, avoiding risks caused by insufficient or excessive oil levels, and improving safety and ease of maintenance.
