Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and in particular to a driver's cab front hood system and a vehicle. Background Technology
[0002] The front hood system is generally used as a safety device to protect the front part of the truck cab. At the same time, the front hood system of cab-over trucks is also one of the exterior parts of commercial vehicles. When the front of the truck is being repaired and inspected, the cab can usually be flipped relative to the vehicle body and tilted forward over the engine to inspect the engine.
[0003] Because of appearance considerations, the fit between the edge of the front hood and the bumper grille of the vehicle body is usually small. In order to avoid interference between the front hood and the bumper grille during the rollover process, which would cause damage to the exterior parts, the rollover of the cab needs to solve the problem of interference between the front hood and the bumper. Summary of the Invention
[0004] The main objective of this invention is to provide a cab front cover system, which aims to provide a sliding front cover to avoid interference between the front cover and the bumper when the cab is tilted, thereby improving the convenience of cab tilting.
[0005] To achieve the above objectives, the present invention provides a cab front cover system comprising:
[0006] The inner panel of the face shield, one side of which is connected to the front bulkhead sheet metal of the cab, and a clearance is provided between the inner panel of the face shield and the bumper grille of the vehicle body; and
[0007] The outer panel of the face mask is slidably connected to the other side of the inner panel of the face mask, and the outer panel can slide relative to the inner panel of the face mask to a preset position; wherein, the preset position includes a clearance position in which at least a portion of the outer panel of the face mask is located in front of the windshield of the cab, and an initial position in which the outer panel of the face mask covers the clearance gap; in the clearance position, interference between the outer panel of the face mask and the cab when tilting forward can be avoided.
[0008] Optionally, at the avoidance position, the outer panel of the mask covers the windshield.
[0009] Optionally, the preset position further includes a shielding position, in which the outer panel of the mask shields the bumper grille.
[0010] Optionally, the inner surface of the mask outer panel facing the bumper grille and the outer surface of the bumper grille are fitted with a clearance fit, and the outer peripheral edge of the mask outer panel is fitted with the edge of the outer peripheral part of the bumper grille.
[0011] Optionally, the outer surface of the mask outer plate is an arc-shaped curved surface.
[0012] Optionally, the cab front mask system further includes a drive unit and a sliding mechanism electrically connected to the drive unit, wherein the outer mask panel is slidably connected to the inner mask panel through the sliding mechanism, and the drive unit drives the sliding mechanism.
[0013] Optionally, the sliding mechanism includes a first sliding member and a second sliding member that cooperate with each other. The first sliding member is connected to the outer panel of the mask, and the second sliding member is connected to the inner panel of the mask. The driving device drives the first sliding member to move relative to the second sliding member.
[0014] Optionally, the cab front cover system further includes a control device for controlling the opening / closing of the drive unit.
[0015] Optionally, the control device is further configured to control the drive device to drive the sliding mechanism according to preset conditions, so that the outer panel of the mask switches between the blocking position and the initial position.
[0016] The present invention also proposes a vehicle comprising:
[0017] The vehicle includes a cab and a body, the body of which is equipped with a bumper grille, and the cab is capable of tilting relative to the body towards the bumper grille; and
[0018] As described above, the cab front hood system has the cab front hood positioned on the front of the cab and above the bumper grille.
[0019] The technical solution of this invention employs an inner mask panel and an outer mask panel. One side of the inner mask panel is connected to the front sheet metal of the cab, and there is a clearance between the inner mask panel and the bumper grille of the vehicle body. The outer mask panel is slidably connected to the other side of the inner mask panel, and the outer mask panel can slide relative to the inner mask panel to a preset position. The preset position includes a clearance position where at least a portion of the outer mask panel is located in front of the windshield of the cab, and an initial position where the outer mask panel covers the clearance gap. At the clearance position, interference between the outer mask panel and the cab when tilting forward can be avoided. The inner and outer panels of the face shield are connected by a sliding connection. When the cab needs to be tilted for maintenance, only the outer panel needs to be moved relative to the inner panel, thus improving the convenience of cab tilting and maintenance. Furthermore, because there are fewer parts, compared to a hinged tilting system, fewer components are needed: traditional hinges or four-bar linkages require more parts to support the tilting of the face shield, while the sliding system reduces the number of parts, thus reducing the overall vehicle weight. It also results in smaller tolerances between parts and higher precision in fit. Moreover, the sliding system eliminates the need to consider the opening angle design of the face shield, increasing design freedom. Compared to a hinged tilting system, reliability is improved: traditional hinges or four-bar linkages are easily affected by external environmental factors such as dust and moisture, leading to problems such as rust and deformation of parts, thus affecting the reliability of cab tilting. The sliding system reduces the occurrence of these problems, thus improving the reliability of cab tilting. Safety is also improved: traditional hinges or four-bar linkages are prone to interference during tilting, causing the face shield to collide with the bumper, thus affecting driving safety. The sliding system avoids this interference problem, thus improving driving safety. Improved aesthetics: Traditional hinges or four-bar linkages expose some components when the vehicle is flipped, affecting its overall appearance. A sliding mechanism, however, conceals these components, thus enhancing the vehicle's aesthetics. Attached Figure Description

[0030] Front hood systems generally serve as safety devices protecting the front of the truck cab. On cab-over trucks, the front hood system is also an exterior component of commercial vehicles. During truck cab maintenance and inspection, the cab can typically tilt forward past the engine for inspection. However, this usually requires flipping the front hood. Currently, the mainstream front hoods on the market are flip-type, with two main types: hinged flip-type and four-link flip-type. Both types require high precision in their movement and coordination with surrounding components, necessitating accurate fit of multiple parts such as handles, hinges, and bolts. This results in a long dimensional chain, larger errors, and lower limiting accuracy. The flip angle is often limited by the wiper system and overall design, preventing the achievement of an ideal angle, reducing aesthetic appeal, and restricting design freedom.
[0031] Therefore, this invention proposes a cab front cover system, which aims to provide a sliding front cover to avoid interference between the front cover and the bumper when the cab is tilted, thereby improving the convenience of cab tilting.
[0032] Reference Figures 1 to 3 In one embodiment of the present invention, the cab front mask system 100 includes an inner mask panel 10 and an outer mask panel 20. One side of the inner mask panel 10 is connected to the front bulkhead sheet metal of the cab, and there is a clearance between the inner mask panel 10 and the bumper grille 40 of the vehicle body. The outer mask panel 20 is slidably connected to the other side of the inner mask panel 10, and the outer mask panel 20 can slide relative to the inner mask panel 10 to a preset position. The preset position includes a clearance position 51 in which at least a portion of the outer mask panel 20 is located in front of the windshield 30 of the cab, and an initial position 52 in which the outer mask panel 20 blocks the clearance. At the clearance position 51, interference between the outer mask panel 20 and the cab when it tilts forward can be avoided.
[0033] The front grille, a crucial exterior component of commercial vehicles, is a large covering located in the center of the cab's front fascia. It must not only meet the overall aesthetic requirements of the vehicle but also fulfill its functional specifications. Its layout and design are complex, requiring systematic consideration of the compatibility, maintenance, ergonomics, and ease of operation of various related components. In vehicles such as cab-over trucks, the cab can typically be tilted relative to the vehicle body, leaning forward beyond the engine for servicing. Due to aesthetic considerations, the fit between the front grille's edge and the vehicle's bumper grille is usually small. To prevent interference between the front grille and bumper grille during tilting, which could damage the exterior components, the cab's tilting mechanism must address the issue of interference between the front grille and the bumper grille.
[0034] There is a clearance between the inner panel 10 of the face mask and the bumper grille 40 of the vehicle body. It should be noted that the clearance here is the clearance between the inner panel 10 of the face mask installed on the front of the cab and the bumper grille 40 without interference during the cab's rollover or forward tilting.
[0035] In traditional designs, the front grille assembly mainly consists of the grille body, frame assembly, hinges, lock assembly, gas springs, grille assembly, spoiler assembly, and some decorative parts. Currently, the mainstream front grilles on the market are flip-up types, including two main types: hinged flip-up grilles and four-link flip-up grilles. Both types require high precision in their movement and interaction with surrounding components, necessitating accurate fit of multiple parts such as armrests, hinges, and bolts to achieve optimal performance. To meet design requirements and facilitate maintenance and operation, the opening angle for maintenance must be precisely determined, while also ensuring ease of closing. Furthermore, the front grille must be rotated along the hinge axis to its maximum opening angle to ensure no interference with the vehicle's surroundings throughout the movement. Because of the long dimensional chain involved, significant errors and low limiting precision, the grille's flip angle is often limited by the wiper system and overall design, preventing the achievement of an ideal flip angle, reducing aesthetic appeal, and restricting design freedom.
[0036] In this design, one side of the inner mask panel 10 is connected to the front sheet metal of the cab, and there is a clearance between the inner mask panel 10 and the bumper grille 40 of the vehicle body; the outer mask panel 20 is slidably connected to the other side of the inner mask panel 10, and the outer mask panel 20 can slide relative to the inner mask panel 10 to a preset position; wherein, the preset position includes a clearance position 51 in which at least a portion of the outer mask panel 20 is located in front of the windshield 30 of the cab, and an initial position 52 in which the outer mask panel 20 blocks the clearance; at the clearance position 51, interference between the outer mask panel 20 and the cab when it tilts forward can be avoided. The inner panel 10 and outer panel 20 of the face mask are slidably connected. When the cab needs to be tilted for maintenance, the outer panel 20 can be moved relative to the inner panel 10. After the outer panel 20 is pushed upward to the clearance position 51, the clearance between the inner panel 10 and the bumper grille 40 of the vehicle body is exposed. In this way, when the cab is tilted, there will be no interference with the bumper grille 40. Moreover, because there are fewer mating parts, the error between parts is smaller and the fitting precision is higher compared with the hinged tilting type. In addition, the sliding method eliminates the need to consider the front face mask opening angle design, which increases the design freedom. With fewer parts, the gap between the face mask system and the cab can be better controlled, thereby improving the appearance.
[0037] In summary, the advantages of using a sliding mechanism for the outer mask plate 20 and the inner mask plate 10 include:
[0038] Reduced number of parts: Traditional hinges or four-bar linkages require more parts to support the flipping of the front grille, while a sliding mechanism can reduce the number of parts, thereby reducing the overall vehicle weight.
[0039] Improved reliability: Traditional hinges or four-bar linkages are susceptible to external environmental factors such as dust and moisture, leading to problems like rust and deformation of components, which affect the reliability of the cab tilting mechanism. Using a sliding mechanism can reduce these problems, thereby improving the reliability of the cab tilting mechanism.
[0040] Improved safety: Traditional hinges or four-bar linkages are prone to interference during rollovers, causing the front grille to collide with the bumper and affecting driving safety. A sliding mechanism avoids this interference problem, thus improving driving safety.
[0041] Improved aesthetics: Traditional hinges or four-bar linkages expose some components when the vehicle is flipped, affecting its overall appearance. A sliding mechanism, however, conceals these components, thus enhancing the vehicle's aesthetics.
[0042] In one embodiment, the inner panel 10 of the mask is connected and fixed to the front bulkhead sheet metal. The inner panel 10 of the mask is connected to the inner part of the front bulkhead sheet metal, so that when the outer panel 20 of the mask is installed, it can cooperate with the side wall of the cab, resulting in good overall integrity. In this solution, the clearance between the inner panel 10 of the mask and the bumper ensures that the inner panel 10 of the mask and the bumper do not interfere when the cab is rolled over. Because the outer panel 20 of the mask cooperates with the side, the movement distance of the outer panel 20 of the mask can be set within the exposed clearance range. The operation method can be manual or electric.
[0043] In another embodiment, the inner mask panel 10 can be connected to the front sheet metal using existing hinges or a four-bar linkage. Since there are no design requirements for flipping, the design requirements are lower. In this solution, the inner mask panel 10 and the outer mask panel 20 can be arranged to the same size. Similarly, the inner mask panel 10 is connected to the inner part of the front sheet metal, so that when the outer mask panel 20 is installed, it can fit with the side wall of the cab, resulting in better overall integrity. Because the inner mask panel 10 can be flipped to create movement space in the direction of the outer mask panel 20, the outer mask panel 20 will not interfere with the windshield 30 or bumper of the cab when it moves relative to the inner mask panel 10.
[0044] Generally speaking, the height or length of the inner mask panel 10 and the outer mask panel 20 may be different, but the clearance between the inner mask panel 10 and the bumper should be avoided to ensure aesthetics and provide protection.
[0045] Reference Figure 1Furthermore, in one embodiment, at the avoidance position 51, the outer mask panel 20 covers the windshield 30. To avoid interference when the cab is rolled over, the outer mask panel 20 only needs to be moved to the height of the avoidance gap. However, after the cab is rolled over, the windshield 30 usually faces the ground. Sometimes, the driver will clean the windshield 30 after the cab is rolled over. If the driver is performing maintenance on the rear side of the cab after it is rolled over, and due to the limitations of the work environment, this height may result in damage to the windshield 30 from unexpected devices. In this case, covering the windshield 30 with the outer mask panel 20 can play a protective role. If someone is picking up a long rod and turns around, it will collide with the outer mask panel 20, which will not cause damage to the windshield 30.
[0046] Aerodynamics plays a crucial role in the design of vehicles such as motor vehicles or road vehicles (carriages, trucks, lorries, etc.). It directly affects fuel consumption and greenhouse gas emissions (especially CO2). Various vehicle components are designed accordingly to optimize the vehicle's aerodynamic performance. This is done to reduce air resistance in commercial vehicles during operation and improve overall fuel economy.
[0047] Reference Figure 3 Furthermore, the preset position also includes a blocking position 53, at which the outer panel 20 of the mask blocks the bumper grille 40.
[0048] Specifically, the outer panel 20 of the hood covers the bumper grille 40, which can improve vehicle safety: covering the bumper grille can reduce injury to pedestrians and other vehicles in the event of a collision. It also improves the vehicle's aesthetics: after sliding, the outer panel 20 can cover the bumper grille, making the overall vehicle appearance more attractive. During driving, it can also improve the vehicle's aerodynamic performance: covering the bumper grille reduces wind resistance, improving aerodynamic performance and thus reducing fuel consumption. At high speeds, the outer panel 20 slides down to the bumper grille 40, forming a closed curved surface that effectively reduces air resistance during driving, resulting in better fuel economy. It also effectively prevents road debris from splashing, protecting the front compartment. Furthermore, it improves vehicle stability: reducing wind resistance improves vehicle stability, thereby enhancing driving comfort and safety.
[0049] Furthermore, to ensure smooth movement between the outer mask panel 20 and the inner mask panel 10, avoid interference, and maintain overall aesthetic integrity, the inner surface of the outer mask panel 20 facing the bumper grille 40 and the outer surface of the bumper grille 40 are fitted with a clearance fit, and the outer peripheral edge of the outer mask panel 20 is in contact with the edge of the outer peripheral component of the bumper grille 40. In other words, during driving, the outer mask panel 20 can slide to the outside of the bumper grille 40, similar to the sliding process of a "slider phone." The clearance fit between the inner surface of the outer mask panel 20 and the outer surface of the bumper grille 40 ensures no interference during sliding and allows the outer mask panel 20 to be closer to the bumper grille 40, maintaining overall aesthetic integrity. Simultaneously, as the outer mask panel 20 slides down to the bumper grille 40, forming a closed curved surface, the outer peripheral edge of the outer mask panel 20 is in contact with the edge of the outer peripheral component of the bumper grille 40, effectively reducing air resistance during vehicle operation.
[0050] Furthermore, the outer surface of the visor outer panel 20 is an arc-shaped curved surface. Arranging the visor outer panel 20 as an arc-shaped curved surface can make the truck's appearance more aesthetically pleasing, while also increasing the vehicle's streamlined shape, reducing air resistance, and improving vehicle driving stability and fuel economy. In addition, the arc-shaped curved surface design can also increase the strength and rigidity of the visor outer panel 20, improve its shock resistance, and thus ensure that the visor outer panel 20 is not easily damaged during driving.
[0051] In other embodiments, the inner mask panel 10 and the outer mask panel 20 may also be arc-shaped panels; or the outer mask panel 20 may be an arc-shaped panel; or the outer side of the outer mask panel 20 may be an arc-shaped curved surface, and the side in contact with the inner mask panel 10 may be a flat surface.
[0052] In traditional designs, the front cover must be manually opened before the cab can be tilted, which is inconvenient. Furthermore, the cab front cover system 100 includes a drive unit and a sliding mechanism 60 electrically connected to the drive unit. The outer cover panel 20 is slidably connected to the inner cover panel 10 via the sliding mechanism 60, and the drive unit drives the sliding mechanism 60. When the cab tilts, the front cover can automatically slide upwards, avoiding interference with the bumper during the tilting motion and improving the convenience of cab tilting.
[0053] In one embodiment, the drive device can be pneumatically driven.
[0054] In another embodiment, the drive device can be electrically driven.
[0055] Specifically, to ensure that the outer mask panel 20 and the inner mask panel 10 slide without interference, the gap and sliding track between them need to be reasonably arranged during the design phase. Special structural designs, such as sliding guides and flanges, can be used to ensure smooth, non-jamming, and interference-free sliding between the outer mask panel 20 and the inner mask panel 10. At the same time, aesthetically pleasing lines and color combinations can be used in the appearance design to ensure overall integrity and aesthetics.
[0056] To drive the outer mask panel 20 to move along the guide rail, an electric motor can be installed on the guide rail. The power of the electric motor is transmitted to the outer mask panel 20 via a transmission device, thereby achieving relative movement of the outer mask panel 20. The transmission device can be a gear, chain, belt, etc., and the specific method selected depends on the actual situation. For reference, the drive device can be electrically driven, using a motor and a connecting mechanism. The connecting mechanism can include a synchronous belt and a connecting rod. The connecting rod connects the first sliding member 61 to the synchronous belt, and the motor drives the synchronous belt to move the connecting rod, thereby driving the first sliding member 61. Alternatively, the first sliding member 61 can be equipped with a rack, and the motor can be mounted on a meshing gear. The motor drives the rack to move the first sliding member 61. A variable speed gear set can also be arranged.
[0057] In one embodiment, the sliding mechanism 60 includes a first sliding member 61 and a second sliding member 62 that cooperate with each other. The first sliding member 61 is connected to the outer panel 20 of the face mask, and the second sliding member 62 is connected to the inner panel 10 of the face mask. The driving device drives the first sliding member 61 to move relative to the second sliding member 62. For example, the sliding mechanism 60 is configured as a high-precision linear guide rail, which can ensure excellent straightness, flatness, perpendicularity and other indicators within a very small error range. In addition, it maintains good stability and accuracy during high-speed movement and has very low noise during operation. Specifically, the sliding member 61 is a slider, and the second sliding member 62 is a slide rail. In order to ensure the sliding stroke, both ends of the slide rail of the second sliding member 62 extend at least to the edge near the inner panel 10 of the face mask. The slider of the first sliding member 61 is extended so that the outer panel 20 of the face mask connected to the slider can be in an avoidance position to cover the windshield or in a blocking position to cover the bumper grille.
[0058] To facilitate the intelligent control of the movement of the outer mask panel 20, the cab front mask system 100 also includes a control device for controlling the opening / closing of the drive device.
[0059] In one embodiment, the control device can be integrated with the vehicle cab system, allowing for active control of lifting from inside the cab.
[0060] Reference Figure 2 and Figure 3In another embodiment, the control device is further configured to control the drive device to drive the sliding mechanism 60 according to preset conditions, so that the outer mask panel 20 switches between the obstructed position 53 and the initial position 52. The preset conditions may be a preset speed, for example, to allow the outer mask panel 20 to actively slide to the outside of the bumper grille 40 during high-speed driving, reducing wind resistance and improving the vehicle's aerodynamic performance, thereby reducing fuel consumption. The control device can also acquire the current vehicle speed. For example, if the vehicle sends its speed information to the control device, the control device compares the speed with a preset speed. When the speed is greater than or equal to the preset speed, the control device controls the drive device to drive the sliding mechanism 60 to move the outer mask panel 20 to the obstructed position 53.
[0061] For example, the outer visor panel 20 can be deployed to the outside of the bumper grille 40 after the vehicle has been determined to exceed a predetermined speed threshold of 60 km / h or 70 km / h.
[0062] If the measured vehicle speed is 70 km / h, the control device, after receiving the speed data / instruction from the vehicle, compares it with the data stored in the control device to determine the descent operation. The electric drive device controls the slide rail to make the outer panel 20 of the front cover slide down along the inner panel 10 of the front cover, and floats in front of the bumper grille 40 following the shape of the bumper grille 40, forming a closed curved angle.
[0063] After the vehicle decelerates, an automatic return function can be added. If the outer panel 20 of the mask is in the position of the bumper grille 40, the control device receives data from the vehicle and determines that the current vehicle speed has dropped below a predetermined speed threshold, such as below 60 km / h. Then, in the same way, the outer panel 20 of the mask is controlled to move back to the initial position 52 before the movement.
[0064] To improve the service life and fit of the outer mask panel 20 and inner mask panel 10, the outer mask panel 20 can be designed as a curved surface. This enhances the overall aesthetics of the vehicle and provides installation protection, reducing damage to the vehicle. To meet the requirements of lightweighting and design freedom, the outer mask panel 20 can be made of various lightweight materials such as glass fiber reinforced composite materials, SMC sheet materials, and carbon fiber reinforced composite materials. The inner mask panel 10 can be designed using lightweight materials such as composite materials and aluminum alloys. This ensures sufficient rigidity and strength for the inner mask panel 10 while reducing the overall weight of the cab and improving fuel economy.
[0065] Furthermore, the length of the outer mask panel 20 is greater than or equal to the length of the inner mask panel 10. To ensure the safety and overall aesthetics of the cab, the length of the outer mask panel 20 should be greater than or equal to the length of the inner mask panel 10, so that the outer mask panel 20 can completely cover the inner mask panel 10 in the length direction.
[0066] Optionally, the length of the outer panel is L, and the length of the inner panel is N. The relationship between L and N satisfies 1≤L / N≤1.4. If the outer panel 20 is smaller than the inner panel 10, the outer panel 20 cannot completely cover the inner panel 10, resulting in a part of the inner panel 10 being exposed, which not only affects the appearance but may also cause safety hazards. If the outer panel 20 is too large, since the sliding mechanism 60 is installed at most at the edge of the inner panel 10, there will be a lot of excess between the outer panel 20 and the sliding mechanism 60, making it difficult to match with the side decoration of the cab and affecting the smoothness of the fit and sliding between the outer panel 20 and the inner panel 10.
[0067] The present invention also proposes a vehicle comprising a cab and a cab front cover system 100. The specific structure of the cab front cover system 100 is as described in the above embodiments.
