Description

Technical Field

[0001] The present application relates to the technical field of commercial vehicles, and in particular to a front face structure of a commercial vehicle. Background Art

[0002] In the commercial vehicle industry, the front face area is a complex area that integrates multiple key components such as the front mask, outer panels and bumper. Under traditional design, the front face area of ​​commercial vehicles is usually equipped with two flip hinges on the upper part of the front mask. When it is necessary to perform necessary maintenance work on various components inside the front enclosure, such as air conditioning, clutch, brake, kettle, gas system, pipelines and electrical components, the operator needs to manually release the locking mechanism of the front mask, and then the front mask can be flipped open around the flip hinge. When the front mask is opened to its maximum angle position, it is usually supported firmly by a mechanical strut to provide a platform for technicians to perform maintenance work on the front enclosure components.

[0003] Only the front hood has the function of flipping open, which undoubtedly limits the area that can be inspected and makes the working space relatively narrow. This limitation not only increases the complexity and challenge of maintenance work, but also significantly reduces the convenience of maintenance operations. Summary of the invention

[0004] The embodiment of the present application provides a commercial vehicle front face structure to solve the problem in the related art that the front cover in the front face area is limited in space for flipping and opening, which increases the complexity and challenge of maintenance work and also significantly reduces the convenience of maintenance operations.

[0005] An embodiment of the present application provides a commercial vehicle front face structure, comprising: a front panel sheet metal, on which a front mask is rotatably connected; a door panel sheet metal, on which an outer panel is rotatably connected; a fixed lock mechanism, which is connected between the front mask and the outer panel; and the commercial vehicle front face structure has a closed state and an open state, when the front mask and the outer panel are rotated to be locked in a first position by the fixed lock mechanism, the commercial vehicle front face structure is in a closed state; when the fixed lock mechanism is unlocked and the front mask and the outer panel are rotated to a second position, the commercial vehicle front face structure is in an open state.

[0006] By adopting the above technical solution: unlocking through the fixed lock mechanism, the front cover and the outer panel can be operated to open, the front cover is flipped upward and the outer panel is rotated to both sides.

[0011] In some embodiments, a first buffer block is connected to the front mask, and a second buffer block is connected to the lock hook. The first buffer block and the second buffer block are respectively abutted against two sides of the handle ring.

[0012] By adopting the above technical solution: the first buffer block prevents one side of the outer plate from loosening outwards, and the second buffer block prevents the other side from shaking inwards, thereby ensuring the reliability of the fixing of the outer plate.

[0013] In some embodiments, a flip hinge is provided on the top of the front wall sheet metal, the front mask is connected to the flip hinge, and a first gas spring is also connected between the front wall sheet metal and the front mask.

[0014] By adopting the above technical solution: the flip hinge allows the front mask to flip at a certain angle relative to the front panel metal, the first gas spring can absorb and disperse the impact force generated by the flipping action, and can also provide assistance for the flipping of the front mask. After the front mask is flipped to the first position, the stability and balance of the front mask are maintained.

[0015] In some embodiments, a four-bar hinge is connected between the door sheet metal and the outer panel, a tension spring is connected between two links of the four-bar hinge, and when the two links are in the maximum open position, the tension spring is in a stretched state.

[0016] By adopting the above technical solution: the connection of the four-link hinge allows the outer side panel to be rotated to a certain angle and opened, and the tension spring helps to lock the door in the second position to prevent it from being accidentally closed.

[0017] In some embodiments, a flip pedal is rotatably connected to the bottom of the front panel, and the flip pedal has a locking position. When the flip pedal is in the locking position, the flip pedal is parallel to the ground.

[0018] By adopting the above technical solution: when the pedal is turned over and rotated to a horizontal state, it can not only be convenient for workers to clean the glass but also be used as a resting platform.

The elastic socket is arranged in an arc shape, and the cross-section of the elastic base is arranged in a circular shape. A flip rocker is connected between the elastic socket and the elastic base, and one end of the flip rocker is clamped with the elastic socket, and the other end is mounted on the elastic base.

[0022] By adopting the above technical solution: by assembling the flip rocker arm proposal with the elastic base and clamping the other end with the elastic clamping seat, the flip rocker arm can be effectively stored, saving space in the cab.

[0023] In some embodiments, a sealing strip is provided on a side of the outer panel close to the front mask.

[0024] By adopting the above technical solution, the provided sealing strip provides reliability for the connection of the outer side panel, reduces the noise generated by the use of the outer side panel, and reduces the collision with the front cover.

[0025] The beneficial effects of the technical solution provided by this application include:

[0026] The embodiment of the present application provides a front face structure of a commercial vehicle. Since the front mask is rotatably connected to the front panel metal, and the outer panel is rotatably connected to the door panel metal, the front mask and the outer panel can both be rotatably opened, so that the open space of the front face area of ​​the commercial vehicle is increased, so as to expand the maintenance space of the front face area and provide convenience for maintenance operations.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] The embodiment of the present application provides a commercial vehicle front face structure, which can solve the spatial limitations of flipping and opening the front cover in the front face area, increase the complexity and challenge of maintenance work, and also significantly reduce the convenience of maintenance operations.

[0042] See also Figures 1 to 10 As shown, an embodiment of the present application provides a commercial vehicle front face structure, including: a front wall sheet metal 1, a door sheet metal 3 and a fixed locking mechanism, wherein the front wall sheet metal 1 is the main supporting structure of the commercial vehicle front face, which is usually located at the front end of the vehicle, adjacent to the engine compartment, and a front mask 2 is rotatably connected to the top of the front wall sheet metal 1; an outer panel 4 is rotatably connected to the door sheet metal 3; and then the fixed locking mechanism is connected between the front mask 2 and the outer panel 4; and the designed commercial vehicle front face structure has a closed state and an open state, when the front mask 2 and the outer panel 4 are rotated to be locked in the first position by the fixed locking mechanism, the commercial vehicle front face structure is in a closed state; when the fixed locking mechanism is unlocked and the front mask 2 and the outer panel 4 are rotated to the second position, the commercial vehicle front face structure is in an open state.

[0043] In the present application, the first position is the position where the front mask 2 and the outer panel 4 are rotated to completely cover the front face area; the second position is the position where the front mask 2 and the outer panel 4 are rotated to the maximum opening angle and the front face area is completely exposed. When in use, the front mask 2 and the outer panel 4 can be operated to open by unlocking through the fixed lock mechanism, and the front mask 2 is flipped upward to open, and the outer panel 4 is rotated to both sides to open. After opening, all machinery, circuits, pipelines, waterways, gas circuits, etc. in the front face area are completely exposed, the maintenance area is greatly increased, and the maintenance convenience is greatly improved. After the maintenance is completed, the front mask 2 and the outer panel 4 are flipped to the first position, and then the front face area is covered, and locked by the fixed lock mechanism to fix the front mask 2 and the outer panel 4 in the first position, and the structure is reliable.

[0044] In the present application, the fixed lock mechanism includes a lock tongue 50, a lock hook 51 and a handle ring 52. Through the BOSS column structure made on the back of the front mask 2 and the pre-embedded nut, the lock tongue 50 cooperates with the nut through screws, thereby effectively fixing the lock tongue 50 on the front mask 2; the lock hook 51 is fixed to the bottom of the front wall sheet metal 1 through the bracket 40; the handle ring 52 is fixed to the outer plate 4 through bolts. When in use, when the front face structure of the commercial vehicle is in a closed state, the lock tongue 50 passes through the handle ring 52 and is hooked on the lock hook 51, thereby effectively fixing the front mask 2 in the first position. At this time, due to the hooking of the lock hook 51 and the lock tongue 50, the handle ring 52 is pressed under the front mask 2, thereby effectively fixing the outer plate 4 by pressing.

[0045] The present application is more convenient than the other application because the fixed lock mechanism is cleverly designed. The front mask 2 and the outer panel 4 can be fixed at the same time by using a set of fixed lock mechanisms, and the front mask 2 and the outer panel 4 are effectively fixed in the first position, so as to close the front face structure of the commercial vehicle. When the front face structure of the commercial vehicle needs to be opened, the locking tongue 50 and the locking hook 51 are unlocked, and then the front mask 2 can be opened first, and then the outer panel 4 can be opened. When closing the front mask 2 and the outer panel 4, the outer panel 4 is first rotated to the first position, and then the front mask 2 is turned down, and the locking tongue 50 and the locking hook 51 are hung and fixed. The operation is convenient and the structure is reliable. Compared with the design of fixing the outer panel 4 with two sets of left and right locking mechanisms in other embodiments, the present application greatly reduces the cost.

[0046] In the present application, in order to conveniently connect the lock hook 51 and the lock tongue 50, the fixed lock mechanism also includes a pull-wire switch 60, which mainly includes a reset handle, a traction rope and a transmission component. The pull-wire switch 60 is a fixed lock mechanism well known to the staff in the field, and will not be described in detail here. By installing the reset handle part on the door sheet metal 3, one end of the pull rope 20 is connected to the lock hook 51, and the other end is connected to the reset handle. The transmission component includes a driving arm, a transmission shaft and a torsion spring, etc. The transmission component is used to transfer the tension of the traction rope to the lock hook 51. The use of the pull-wire switch 60 can control the locking or unlocking of the lock hook 51. The staff pulls the reset handle out of the door sheet metal 3, and then effectively pulls the lock hook 51 under the traction of the traction rope and the transmission of the transmission component, so that the lock hook 51 is opened. When the lock hook 51 is opened, the lock tongue 50 is passed through the handle ring 52 and hung on the lock hook 51, and then the reset handle is released, and the lock hook 51 is automatically closed, effectively realizing the hooking and fixing of the lock hook 51 and the lock tongue 50. At this time, the front face structure of the commercial vehicle is in a closed state. When the front face structure of the commercial vehicle needs to be opened, the reset handle is also moved by the plate, and then the lock hook 51 is effectively pulled under the traction of the traction rope and the transmission of the transmission component, so that the lock hook 51 is opened, and then the front face 2 is flipped upward. At this time, the lock tongue 50 is effectively detached from the lock hook 51 under the action of external force, and the front face 2 is flipped upward to the second position, and then it is rotated on the outside to its maximum opening angle so that it is in the second position. The commercial vehicle front face structure is completed and is in an open state, which is convenient to use.

[0047] In the present application, in order to strengthen the fixation of the outer panel 4, a first buffer block 520 is connected to the front mask 2, and at least two first buffer blocks 520 are provided. A second buffer block 521 is connected to the lock hook 51. When the front face structure of the commercial vehicle is in a closed state, the first buffer block 520 and the second buffer block 521 are respectively abutted against the two sides of the handle ring 52, thereby effectively limiting the front and rear sides of the handle ring 52, so that the handle ring 52 is firmly pressed. At this time, the outer panel 4 is completely fixed to prevent one side of the outer panel 4 from loosening outward and the other side from shaking inward. When the outer panel 4 needs to be opened, it only needs to unlock the front mask 2, and the pressure of the outer panel 4 will be released immediately.

[0048] In addition, a sealing strip 44 is provided on one side of the outer panel 4 close to the front cover 2 to further improve the connection reliability between the outer panel 4 and the front cover 2 and reduce the noise generated during the driving of the vehicle.

[0049] In the present application, the rotation connection method of the front mask 2 and the front panel includes, but is not limited to, setting a flip hinge 70 at the top of the front panel sheet metal 1, the front mask 2 is connected to the flip hinge 70, and a first gas spring (not shown in the figure) is connected between the front panel sheet metal 1 and the front mask 2. The flip hinge 70 allows the front mask 2 to flip at a certain angle relative to the front panel sheet metal 1, so as to facilitate the opening and closing of the front mask 2, and after the front mask 2 is rotated upward, when the front mask 2 is in the process of flipping, the first gas spring can absorb and disperse the impact force generated by the flipping action, and can also provide assistance for the flipping of the front mask 2, and after the front mask 2 is flipped to the first position, the stability and balance of the front mask 2 are maintained.

[0050] In the present application, since the height of the front cover 2 of a commercial heavy truck reaches 1.85 meters after being fully opened, some operators may not be able to reach the front cover 2 to close it, so the front cover 2 is flipped over, the inner side of the front cover 2 is connected to a pull rope 20 at the top, and the front cover 2 is closed with the help of the drooping pull rope 20.

[0051] In the present application, the connection method of the outer panel 4 includes, but is not limited to, a four-link 82 hinge is connected between the door sheet metal 3 and the outer panel 4. The four-link 82 hinge structure is usually composed of a frame 80, a connecting frame 81 and a connecting rod 82. The length of each component is designed according to the usage. The frame 80 is fixed to the door sheet metal 3 as a fixed component, and the two connecting rods 82 are rotatably connected between the frame 80 and the connecting frame 81. The connecting frame 81 is fixed to the outer panel 4, and the connecting frame 81 rotates relative to the frame 80. The two connecting rods 82 move in a plane, and the ends of the two connecting rods 82 close to the frame 80 are both set as fixed ends 83, and then locking concave points 84 are respectively provided on the two connecting rods 82. When the connecting rods 82 move in a plane, the fixed end 83 on one connecting rod 82 abuts against the locking concave point 84 on the other connecting rod 82, and when the fixed end 83 abuts against the locking concave point 84, the two connecting rods 82 are in the maximum open position. Since the outer panel 4 is rotatably connected to the door sheet metal 3 through the four-link 82 hinge, when the outer panel 4 is in the first position, the four-link 82 hinge also has a first rotation state, and when the outer panel 4 is in the second position, the four-link 82 hinge has a second rotation state. In the first rotation state and the second rotation state, the fixed end 83 on one link 82 abuts against the locking concave point 84 on the other link 82. During operation, when a rotational external force is applied to the outer panel 4 at the handle ring 52, the relative rotation tendency of the outer panel 4 will be transmitted to the link 82. Based on the relative movement between the link 82, when one of the link 82 moves as an active part, the other link 82 will also move accordingly until the fixed end 83 abuts against the locking concave point 84, and the two link 82 are in the maximum open position, thereby achieving smooth transmission and the outer panel 4 effectively switching between the open and closed states. A tension spring 85 is then connected between the two links 82 of the four-link hinge 82. When the two links 82 are in the maximum open position, the tension spring 85 is in a stretched state, which helps to lock the outer panel 4 in the second position to prevent it from being accidentally closed.

[0052] In the present application, a reversing pedal 9 is rotatably connected to the bottom of the front panel 1, and the reversing pedal 9 has a locking position. When the reversing pedal 9 is in the locking position, the reversing pedal 9 is parallel to the ground. The locking position is the position where the reversing pedal 9 is in a horizontal state after the reversing pedal 9 is turned 90 degrees around the rotation center. Therefore, when the staff wants to clean the front glass of the vehicle, they can step on the reversing pedal 9 to operate, or put the reversing pedal 9 down as a resting platform.

[0053] In the present application, the connection method of the flip pedal 9 includes, but is not limited to, a movable frame 90 is rotatably connected to the bottom of the front wall sheet metal 1, the movable frame 90 has a hook structure, which can be hung on the bottom of the front wall sheet metal 1 and rotate around its periphery, one end of the movable frame 90 is fixed to the front wall sheet metal 1, and the other end is rotatably connected to the movable frame 90, and finally a second gas spring 92 is connected between the movable frame 90 and the fixed frame 91. After use, the flip pedal 9 is pushed upward, and it is flipped and reset under the action of the second gas spring 92, and the structure is reliable.

[0054] In the present application, it is also considered that the cab flip rocker 43 of the traditional commercial vehicle is stored inside the cab, occupying the indoor space. Based on the design consideration that the outer panel 4 can be flipped open, the present application connects a bracket 40 to the inner side of the outer panel 4, and an elastic base 41 is provided at the bottom of the bracket 40, and an elastic base 42 is provided at the top, and the elastic base 41 is arranged in an arc shape, and the cross section of the elastic base 42 is arranged in a circular shape, and a flip rocker 43 is connected between the elastic base 41 and the elastic base 42, and one end of the flip rocker 43 is clamped with the elastic base 41, and the other end is sleeved on the elastic base 42, so that the flip rocker 43 can be effectively stored on the outer panel 4, and the flip rocker 43 is divided into two sections and inserted and stored in the left and right outer panels 4 respectively. When it is needed, it only needs to take off the two sections of the rocker respectively, and assemble them together for use, which greatly saves the space in the cab.

[0055] The implementation principle of the present application is: unlock by controlling the fixed lock mechanism, the lock hook 51 is opened, and then the front mask 2 is flipped upwards. At this time, the lock tongue 50 is effectively detached from the lock hook 51 under the action of external force, the front mask 2 is flipped upwards, and the outer plate 4 is flipped outwards and opened. At this time, the front face structure of the commercial vehicle is in an open state, and the maintenance space is large. After the maintenance is completed, the outer plate 4 is first turned to close, and then the pull rope 20 is pulled to flip the front mask 2 downward. At this time, the fixed lock mechanism is unlocked by controlling the lock hook 51, and the lock hook 51 is opened. When the front mask 2 is flipped to the first position, the lock tongue 50 is hung on the lock hook 51 and the fixed lock mechanism is locked. The first buffer block 520 and the second buffer block 521 press the handle ring 52 tightly, and then the outer plate 4 is effectively fixed in the first position through the compressed structure. At this time, the front face structure of the commercial vehicle is in a closed state. The overall operation is convenient and the structure is reliable.
