Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of a cab, in particular to a cab and a vehicle. BACKGROUND

[0002] Traditional cab suspensions usually adopt a fixed design that cannot be turned over. This suspension structure is relatively simple, but has significant drawbacks. Since the bottom of the cab is fixed, it is extremely difficult to overhaul the chassis components. In addition, components such as hydrogen cylinders and batteries are often arranged behind the cab, and it is also extremely inconvenient to maintain and inspect between the bottom of these components and the bottom of the cab, which greatly disturbs the daily maintenance and use of users.

[0003] In order to solve the above problems, some new cab suspensions have emerged. This design adds a turning shaft at the front of the cab suspension, and at the same time makes the rear suspension disconnectable, so that the cab can be turned over along the turning shaft. This structure design significantly improves the maintenance convenience of the engine or battery components at the bottom of the cab. However, as drivers' demand for cab comfort continues to rise, more and more living facilities are gradually integrated into the cab, such as living supplies, washing supplies, water pipes, refrigerators, etc. The size of the cab increases, and the function is more complex. With the increase of the size and weight of the cab, the lever power required for the turning operation is greatly improved, and the length of the turning mechanism also needs to be increased, making the overall arrangement extremely difficult. In addition, there are many types of living facilities in the cab, and during the turning process, the goods may fall or slide, which not only may damage the front windshield, but also may pose a safety threat to the driver and the vehicle.

DETAILED DESCRIPTION

In addition, the terms "first", "second", "third", and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0031] In addition, the terms "horizontal", "vertical", and the like do not mean that the components must be absolutely horizontal or suspended, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0032] In the description of the present application, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] An aspect of the embodiment of the present application provides a cab for a vehicle, comprising a slide rail assembly 11, a sliding assembly 12 and a cab body 13, which is designed by reasonable structure layout and technology to improve the functionality of the cab and the overall maintenance convenience and use flexibility of the vehicle.

[0034] As shown in Figure 1 The slide rail assembly 11 is connected to the vehicle frame 21, and the length direction of the slide rail assembly 11 is parallel to the length direction of the vehicle frame 21. This parallel design helps to ensure the stability and direction consistency of the cab body 13 during sliding, avoiding structural jamming or functional abnormalities caused by lateral deviation. The slide rail assembly 11 is usually made of high-strength material to withstand the weight of the cab body 13 and the attached objects, and has high wear resistance to ensure smooth sliding performance in long-term use.

[0035] The cab body 13 is slidably connected to the slide rail assembly 11 through the sliding assembly 12 to form a whole movable cab structure. Specifically, the cab body 13 can be fixed on the sliding assembly 12 by threaded connection, clamping or insertion, etc. When the sliding assembly 12 is driven to slide along the slide rail assembly 11, it can drive the cab body 13 to slide synchronously. This design allows the cab body 13 to be adjusted in front and back displacement as needed. For example, when the engine at the bottom of the cab or the vehicle chassis parts need to be repaired, the cab body 13 can be slid to the appropriate position to provide enough maintenance space and improve the convenience of vehicle maintenance. It should be noted that the sliding assembly 12 usually integrates roller, ball or slider structure, and combines with low friction material and guide design to reduce sliding resistance. At the same time, in order to ensure the accurate positioning of the sliding assembly 12 on the slide rail assembly 11, the slide rail assembly 11 can be provided with a limiting device or a guide groove to prevent the sliding assembly 12 from derailing or over-sliding.

[0036] Overall, the embodiment of the present application enables the cab body 13 to translate along the length direction of the vehicle by the cooperation of the slide rail assembly 11 and the sliding assembly 12, ensures that the internal facilities of the cab body 13 always remain in a horizontal state, avoids the risk of internal facilities or articles in the cab body 13 falling, sliding or even injuring personnel during the turnover, and significantly improves the operation safety. In addition, the sliding design can also avoid the problems of large turnover operation difficulty and large space occupation. Only by translating the cab body 13 along the slide rail assembly 11 can the chassis maintenance area be left, which greatly reduces the operation complexity and improves the convenience of maintenance, and is suitable for vehicles with large cab volume and weight.

[0037] Optionally, as shown in Figure 1 , the cab further includes a suspension assembly, which can be fixed on the vehicle frame 21 by screw connection, clamping, insertion or welding, etc. The slide rail assembly 11 can also be fixed on the suspension assembly by screw connection, clamping or insertion, etc. Through the damping function of the suspension assembly, the stability and comfort of the cab body 13 during sliding and driving can be improved.

[0038] Specifically, the suspension assembly is usually composed of elastic elements and damping elements, which are used to absorb the vibration impact from the road during vehicle driving, so as to protect the slide rail assembly 11 and the cab body 13 connected thereto from excessive vibration force. At the same time, the elastic design of the suspension assembly enables the slide rail assembly 11 to adapt to the slight deformation or displacement of the vehicle frame 21, preventing structural fatigue or damage caused by rigid connection. The suspension assembly is usually arranged at the fixed point of the slide rail assembly 11, and adopts a multi-point support design to better realize the damping function of the cab body 13. According to the type and use scene of the vehicle, different suspension forms can be selected. For example, for heavy vehicles, an air suspension system can be used to provide stronger damping capacity; while for light vehicles, rubber shock absorbing blocks can be used to realize lightweight design. In addition, the stiffness and damping parameters of the suspension assembly need to be matched with the weight of the slide rail assembly 11 and the cab body 13, so as to ensure the balance between damping performance and structural strength.

[0039] Optionally, as shown in Figure 1 , the suspension assembly includes a first shock absorber 161 and a second shock absorber 162, which are arranged in the length direction of the vehicle frame 21. This layout not only has good balance in structural design, but also can improve the vibration resistance and dynamic stability of the cab by reasonably distributing the damping points, providing efficient damping protection for the operation of the overall system.

[0040] Specifically, the first shock absorber 161 and the second shock absorber 162 can absorb and dissipate vibration energy through the deformation of the elastic element, and convert the vibration into heat energy or other forms of dissipated energy through the damping element, thereby reducing the vibration amplitude. Arranging the first shock absorber 161 and the second shock absorber 162 at both ends of the slide rail assembly 11 in the length direction respectively can form a distributed flexible support structure. The first shock absorber 161 is responsible for buffering the vibration force transmitted by the front part of the vehicle frame 21, while the second shock absorber 162 acts on the rear part, so that the two shock absorbers uniformly disperse the dynamic load from different positions of the vehicle frame 21, and provide multi-point support in the dynamic operation of the vehicle, forming an effective vibration isolation system.

[0041] Among them, the first shock absorber 161 and the second shock absorber 162 can adopt various shock absorption forms, such as rubber springs, hydraulic dampers, air springs, etc., which are selected according to the load requirements and vibration characteristics of the vehicle. Preferably, in heavy vehicles, high-stiffness hydraulic shock absorbers can be combined with rubber springs to cope with larger vibrations and impacts; while in light vehicles, air springs and low-damping elements can be combined to reduce system weight and improve shock absorption performance.

[0042] Optionally, as shown in Figure 1 The cab also includes a telescopic member 14, the fixed end of which is connected to the slide rail assembly 11 to ensure stable operation during force application; the telescopic end of the telescopic member 14 is connected to the sliding assembly 12 to achieve smooth driving of the sliding assembly 12. The telescopic member 14, as a driving force transmission component, forms a mechanical linkage relationship with the slide rail assembly 11 and the sliding assembly 12. The slide rail assembly 11 provides a sliding path, and the telescopic member 14 generates a linear driving force through controlled telescopic movement, which acts on the sliding assembly 12 to move it along the length direction of the slide rail assembly 11, thereby achieving synchronous sliding of the cab body 13.

[0043] Overall, through the driving of the telescopic member 14, the cab body 13 can smoothly slide on the slide rail assembly 11, which can avoid the safety hazards caused by the inclination of the cab body 13 during the turnover process, and reduce the impact and damage risk to the internal facilities of the cab body 13, thereby greatly improving the efficiency and reliability of the movement of the cab body 13. In addition, the introduction of the telescopic member 14 makes the sliding operation of the cab body 13 more simple and controllable, and the driver or maintenance personnel can achieve smooth movement of the cab body 13 through simple control devices, thereby greatly improving the maintenance convenience and operation experience.

[0044] Optionally, the telescopic member 14 is an electric push rod, a hydraulic push rod or an air cylinder. This variety of designs makes the telescopic member 14 more flexible and adaptable, which can be flexibly selected according to the use environment, load requirements and economy of the vehicle, thereby improving the practicability and reliability of the cab.

[0045] Specifically, the electric push rod, the hydraulic push rod and the air cylinder are common linear driving devices, each having unique performance characteristics. The electric push rod uses a motor as a power source and realizes linear motion through a screw rod drive, has the characteristics of compact structure, high precision and flexible control, and is particularly suitable for light vehicles or specific functional scenarios with high requirements for motion control accuracy. The hydraulic push rod drives the piston to move through the liquid pressure, has a large output force and stability, and is very suitable for heavy vehicles or scenarios that need to bear high load. The air cylinder uses compressed air as driving force, has fast action and sensitive response, and is suitable for working conditions with high speed requirements or harsh use environment. The core function of the three driving forms is to provide linear driving force to drive the sliding assembly 12 to move along the slide rail assembly 11, so as to realize the smooth sliding of the cab body 13.

[0046] Optionally, as shown in Figure 2 The parallel arrangement of the two slide rails 111 can provide a guide reference for the sliding assembly 12, and the first cross beam 112 stably connects the two slide rails 111 together through a reliable fixing method, which not only enhances the overall rigidity of the slide rail assembly 11, but also ensures the consistency of the distance between the two slide rails 111, avoiding the running of the sliding assembly 12 due to deformation or displacement. This design can effectively adapt to the length direction of the vehicle frame 21, and provide a solid foundation for the smooth running of the sliding assembly 12.

[0047] The sliding assembly 12 is composed of two slide rods 121 arranged in parallel and spaced apart, and a second cross beam 122 connecting the two slide rods 121. The design of the sliding assembly 12 is highly matched with the slide rail assembly 11, forming a precise sliding fit. The two slide rods 121 are respectively slidingly connected in different slide rails 111, and through reasonable gap design and surface treatment, the sliding process of the slide rod 121 in the slide rail 111 is stable, smooth and free of jamming. The second cross beam 122 as a connecting component between the slide rods 121 can not only improve the structural strength of the sliding assembly 12, but also ensure the synchronization of the two slide rods 121 in the sliding process, thereby avoiding the situation of unilateral stress or sliding deviation.

[0048] It should be noted that the two slide rails 111 of the slide rail assembly 11 can be made of high-strength steel or aluminum alloy to meet the dual requirements of strength and light weight. The surface of the slide rail 111 can be treated by electroplating or spraying to enhance wear resistance and corrosion resistance. The first cross beam 112 is fixed between the two slide rails 111 by welding or bolting to ensure the reliability and stability of the structure. The slide rod 121 in the sliding assembly 12 can also be made of wear-resistant material, and its end is connected with the slide rail 111 through a bearing, a sliding sleeve or a guide rail slider to reduce sliding friction and improve sliding accuracy. The second cross beam 122 and the slide rod 121 can be connected by welding or mechanical connection to ensure the rigidity and uniformity of the overall structure. In addition, the contact surface of the slide rail 111 and the slide rod 121 can be treated by lubrication process to reduce sliding resistance and wear, and ensure the long-term reliable operation of the system.

[0049] Alternatively, as shown in Figure 2 In order to enhance the positioning accuracy and stability of the sliding assembly 12 relative to the slide rail assembly 11, and prevent unnecessary sliding in non-working state or accidental situation, the cab is also designed with a limiting piece 15, such as a limiting pin. The limiting piece 15 limits the sliding stroke of the sliding assembly 12 to a specific position through structural cooperation, enhances the movement control ability of the sliding assembly 12, and avoids safety hazards that may be caused by excessive sliding, accidental sliding or misoperation. At the same time, the use of the limiting piece 15 makes the slide rail assembly 11 and the sliding assembly 12 form a rigid connection in a certain state, effectively improving the stability of the cab in the transportation, maintenance or static state.

[0050] Specifically, as shown in Figure 3 and Figure 4 A first limiting hole 112a is opened in the first cross beam 112, and a second limiting hole 122a is opened in the second cross beam 122. The positions of the first limiting hole 112a and the second limiting hole 122a are accurately calculated to ensure that they can be accurately aligned when the sliding assembly 12 reaches a specific position, thereby allowing the limiting piece 15 to pass through. The insertion of the limiting piece 15 can effectively prevent the sliding assembly 12 from further moving relative to the slide rail assembly 11, thereby achieving reliable sliding locking. Such a structure is simple and practical, and the limiting function can be easily released by pulling out the limiting piece 15 to restore the sliding function.

[0051] The limiting piece 15 is usually made of high-strength material, such as alloy steel or stainless steel, to ensure that it can withstand the inertial impact force when the sliding assembly 12 slides and the external load. In addition, the machining accuracy of the first limiting hole 112a and the second limiting hole 122a should meet the smoothness of the insertion of the limiting piece 15 and the reliability of the limiting mechanism. Reasonable gap design of the limiting holes can ensure the convenience of inserting and pulling out the limiting piece 15 while avoiding excessive looseness, and ensure the stability of the limiting mechanism during long-term operation.

[0052] In addition, the limiting member 15 can be designed as a manual operation or an automatic control. For the manual limiting member 15, the driver or the maintenance personnel can complete the operation through a simple plug-in action when locking or releasing the sliding function is needed, which is suitable for the manual intervention requirement of maintenance or special scene. While for the limiting member 15 of automatic operation, the insertion and extraction of the limiting member 15 can be controlled through electromagnetic drive or hydraulic mechanism combined with the electric control system, to realize the remote control or automatic locking function, which is more suitable for high-end vehicles or application scenarios with higher automation requirements.

[0053] Optionally, as shown in Figure 2 two second cross beams 122 are arranged in parallel and spaced between the two slide rods 121, and the two second cross beams 122 are respectively located at the two ends of the slide rod 121, which can play a role in connecting and supporting the slide rod 121. By arranging two second cross beams 122 at the two ends of the slide rod 121, the structural rigidity and stress uniformity of the sliding assembly 12 can be further improved, thereby enhancing the stability and reliability of the cab body 13 during the sliding process.

[0054] During maintenance, in order to facilitate the maintenance of the bottom of the vehicle or other components, it is usually necessary to slide the cab body 13 along the length direction of the slide rail assembly 11 forward to leave a maintenance space. In order to realize the rationality of the structure and the convenience of the operation, a plurality of first cross beams 112 are arranged between the two slide rails 111, and the first cross beams 112 are distributed at the two ends and the intermediate position of the slide rail assembly 11. The first cross beams 112 located at the two ends can provide boundary support for the overall structure, and one of the first cross beams 112 located in the middle of the slide rail 111 can be used as a fixed end of the telescopic member 14, to provide a stable mounting base for the driving system. This layout can optimize the carrying capacity of the slide rail assembly 11, while ensuring that the force of the telescopic member 14 can be uniformly transmitted to the entire sliding assembly 12. The telescopic end of the telescopic member 14 is fixedly connected to the second cross beam 122 at the front end, and such a design enables the sliding assembly 12 to smoothly slide forward along the slide rail assembly 11 when the telescopic member 14 is extended, thereby driving the cab body 13 to move synchronously to release the maintenance space. When the telescopic member 14 is retracted, the sliding assembly 12 can smoothly slide backward along the slide rail assembly 11, thereby driving the cab body 13 to move synchronously to return to the driving position.

[0055] In addition, in order to further improve the stability and safety of the sliding assembly 12 in the limit position, a first limiting hole 112a is formed on the first cross beam 112 at the rear end, and a second limiting hole 122a matched with the first limiting hole 112a is formed on the second cross beam 122 at the rear end. When the cab body 13 is in the driving position, the limiting piece 15 can be inserted into the two limiting holes to form a rigid limiting structure, thereby effectively preventing the excessive movement of the sliding assembly 12 and ensuring the stability of the cab during driving.

[0056] Alternatively, as shown in Figures 2 to 4 for further optimizing the sliding and limiting design of the cab, a third cross beam 113 parallel to and spaced from the first cross beam 112 is additionally arranged between the two slide rails 111. The third cross beam 113 not only increases the overall support of the slide rail assembly 11, but also has a third limiting hole 113a formed thereon to achieve more precise positioning and limiting control when the cab body 13 slides.

[0057] Specifically, the cab has two main working states: driving position and maintenance position. As shown in Figure 1 and Figure 5 When the cab is in the driving position, the limiting piece 15 is precisely fitted into the first limiting hole 112a and the second limiting hole 122a to ensure that the cab body 13 does not slide or move unexpectedly during normal driving. This limiting structure can effectively prevent the cab from moving unexpectedly, thereby ensuring driving safety. As shown in Figure 2 and Figure 6 When the cab needs to be moved to the maintenance position, the limiting piece 15 is first pulled out of the first limiting hole 112a and the second limiting hole 122a, and then the sliding assembly 12 is driven by the telescopic piece 14 to make the cab body 13 slide along the slide rail 111 to the maintenance position. After reaching the maintenance position, the limiting piece 15 is fitted into the first limiting hole 112a and the third limiting hole 113a to form a new limiting position, ensuring precise control and positioning of the cab body 13 when it slides to the maintenance position. In this way, the system not only provides sufficient operating space for maintenance, but also effectively prevents any safety hazards during maintenance. It should be noted that, in order not to damage the integrity of the cross beam, a protrusion can be provided on the cross beam, and the limiting hole is formed in the protrusion.

[0058] In another aspect of the embodiment, a vehicle is provided, which can be a new energy heavy truck or other vehicle with a large cab volume and weight, as shown in Figure 5 and Figure 6 The vehicle includes a vehicle frame 21 and any of the above-mentioned cabs, and the cab body 13 of the cab is slidingly connected to the vehicle frame 21. Since the vehicle adopts the above-mentioned cab, it also has the same beneficial effects as the cab, which will not be described here.

[0059] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
