[0040] When a heavy commercial vehicle is inspected and repaired, the cab needs to be flipped and lifted. When the cab is flipped, the inspection window set at the vehicle pedal will be opened to perform inspection and maintenance inside the vehicle. The inspection window is covered by a step cover, and the step cover will be opened when inspection is needed.

[0041] At present, commercial vehicles generally fix step covers on the vehicle in two ways: snap-on fixing and flip-up fixing. For the snap-on step cover, an anti-lost rope is provided on the step cover and is snap-on and fixed to the step body. The snap-on step cover is prone to wear and tear after repeated use, and the anti-lost rope is prone to breakage. In addition, round or square holes need to be provided on the surface of the snap-on step cover for disassembly, which affects the overall appearance of the product.

[0042] As for the existing flip-type step cover, a rotating shaft and two shaft pins are provided on the step cover, two metal clips are installed on the step body, and the metal clips are fixed by interference fit. Therefore, the flip-type cover has the disadvantages of being inconvenient to disassemble and assemble, difficult to operate, and having a disadvantage of being stuck when opening.

[0043] Based on this, the embodiment of the present application proposes a push-type locking system on a vehicle, which can be used in the field of heavy-duty commercial vehicles. It aims to solve the above technical problems of the prior art. Through the mutual cooperation of the pressing module and the Z-shaped spring arranged on the step body, the opening and closing of the flip step cover plate is realized, thereby avoiding the defects of difficult operation and opening jamming caused by the existing interference fit scheme, and thus facilitating the operation of maintenance personnel during the maintenance of commercial vehicles, thereby improving the maintenance efficiency of heavy-duty commercial vehicles.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Figure 1 This is a schematic diagram of the closing structure of the push-type locking system on a vehicle provided in an embodiment of the present application. Figure 6 A schematic diagram of a step cover provided in an embodiment of the present application, combined with Figure 1 and Figure 6 As shown, the push-type locking system on the vehicle includes: a pedal body 105, a step cover 101, a Z-shaped spring 103, and a push module 104, wherein the push module 104 has a locking pin;

[0046] The step cover 101 is arranged at the opening of the pedal body 105, that is, the step cover 101 is arranged at the vehicle maintenance window, one end of the Z-shaped spring 103 is fixed on the back of the step cover 101, and the other end of the Z-shaped spring 103 is fixed on the fixing bracket 102, and the fixing bracket 102 is arranged on the pedal body 105;

[0047] The pressing module 104 is disposed on the pedal body 105 , and a locking hole corresponding to the position of the locking pin of the pressing module 104 is disposed on the step cover 101 , and the locking pin can be inserted into the locking hole.

[0048] Furthermore, when the push-type locking system on the vehicle is in a closed state, that is, the step cover 101 is in a closed state, when the locking pin of the pressing module 104 is inserted into the locking hole in the step cover 101, the step cover 101 covers the opening of the pedal body 105, that is, when the step cover 101 is in a closed state, the inspection window of the heavy vehicle is closed, and the Z-shaped spring 103 is in an extended state.

[0049] Furthermore, a fixing hole for fixing the Z-shaped spring 103 is provided on the step cover plate 101 , the locking hole and the fixing hole are located on two opposite sides of the step cover plate 101 , a raised structure is provided on the back side of the step cover plate 101 , and a locking hole is provided on the raised structure 101 .

[0050] Furthermore, when the latch is disengaged from the lock hole, the step cover plate 101 is perpendicular to the plane where the opening of the pedal body is located.

[0051] The embodiment of the present application provides a push-type locking system on a vehicle, which realizes flipping and connecting one side of a step cover plate to a step body through a solid bracket, and cooperates with the locking pin of the pressing module with the locking hole on the flip-type step cover plate to realize movably connecting the other side of the step cover plate to the step body, so as to close the flip-type step cover plate and cover and close the maintenance window of the heavy-duty vehicle through the step cover plate, thereby avoiding the defects of difficult operation and opening and closing jamming caused by the existing interference fit scheme, and thus facilitating the operation of maintenance personnel when repairing commercial vehicles, thereby improving the maintenance efficiency of heavy-duty commercial vehicles.

[0052] based on Figure 1 Embodiment: The opening state of the push-type locking system on the vehicle is described in detail below.

[0053] Figure 2 A schematic diagram of the opening structure of the push-type locking system on a vehicle provided in an embodiment of the present application is shown in Figure 2. When the push-type locking system on the vehicle is in the open state, that is, the step cover 101 is in the open state, when the locking pin of the pressing module 104 is disengaged from the locking hole in the step cover 101, the step cover 101 is supported by the pin shaft and the elastic force of the Z-shaped spring 103. The step cover 101 is pushed away from the opening of the pedal body 105 to achieve the step cover 101 Rotate to open a preset angle such as ninety degrees, that is, the inspection window of the heavy vehicle is opened to a preset angle. At this time, the Z-shaped spring 103 is in the expanded state, that is, when the pin is disengaged from the locking hole, the step cover is perpendicular to the plane where the opening of the pedal body is located.

[0054] Furthermore, the opening angle of the step cover 101 can of course be set to other angles, as long as the maintenance personnel can inspect and maintain the interior of the heavy vehicle through the opened maintenance window. Other opening angles can be achieved by selecting different types of Z-shaped springs.

[0055] Furthermore, the step cover plate 101 is provided with two spring fixing holes that cooperate with the vertical rod at one end of the Z-shaped spring 103, that is, fixing holes for fixing the Z-shaped spring 103. The two spring fixing holes cooperate with the vertical rod at one end of the Z-shaped spring 103 to fix one end of the Z-shaped spring 103 on the step cover plate 101, and the other end of the Z-shaped spring 103 is arranged on the pedal body 105 through the fixing bracket 102, so that the self-limiting of the step cover plate 101 is achieved through the contact between the unfolded Z-shaped spring 103 and the fixing bracket 102.

[0056] The embodiment of the present application proposes a push-type locking system on a vehicle, which controls a button on the push module so that the locking pin in the push module disengages from the locking hole on the step cover plate, and opens the step cover plate under the thrust generated by the Z-shaped spring changing from a compressed state to an extended state, thereby realizing opening the maintenance window of the heavy-duty vehicle through the step cover plate, thereby avoiding the defects of difficult operation and opening jamming caused by the existing interference fit scheme, and thus facilitating the operation of maintenance personnel when repairing commercial vehicles, thereby improving the maintenance efficiency of heavy-duty commercial vehicles.

[0057] The specific structure of the push module 104 in the push-type locking system on the vehicle is described in detail below.

[0058] Figure 3 Schematic diagram of the pressing module structure provided in the embodiment of the present application Figure 1 , Figure 5 A schematic diagram of closing and opening the push-type locking system provided in the embodiment of the present application, combined with Figure 3 and Figure 5 As shown, the pressing module 104 includes: a bottom plate 302 , a fixing plate 301 , a button 304 , a return spring 305 , and a fixing screw hole 306 . The fixing screw hole 306 is used to fix the pressing module 104 on the pedal body 105 .

[0059] The fixing plate 301 covers the bottom plate 302, and a cavity is formed between the fixing plate 301 and the bottom plate 302. A portion of the button 304, a portion of the reset spring 305 and a portion of the lock pin 303 are located in the cavity; another portion of the button 304 and another portion of the lock pin extend out of the fixing plate 301; and both ends of the reset spring 305 are respectively fixed on the fixing plate 301 and the lock pin.

[0060] Furthermore, there are two fixing screw holes 306, which are respectively located on two opposite sides of the pressing module 104. The pressing module 104 is bolted and fixedly connected to the pedal body 105 through the fixing screw holes 306, so that maintenance personnel can control the opening and closing of the step cover 101 through the button 304 on the pressing module 104 to improve maintenance efficiency.

[0061] Furthermore, the locking pin 303 has a curved structure, and the button 304 is in contact with the curved structure and can move on the curved structure, so that when the button 304 is pressed, the button 304 contacts the locking pin 303, and the locking pin 303 is retracted through the spherical and curved surface motion pair relationship at the contact position, that is, the locking pin 303 moves along the curved structure toward the bottom plate 302, and the return spring 305 is compressed to make the protruding part of the locking pin 303 retreat into the fixed plate 301.

[0062] Furthermore, when the button 304 is released, the lock pin 303 is extended under the push of the return spring 305, and the button 304 is reset through the spherical and curved surface motion pair relationship at the contact position, that is, when the button 304 is released, the elastic force of the return spring 305 pushes the lock pin 303 out of the fixed plate 301.

[0063] When the push-type locking system on the vehicle is in the closed state, that is, the step cover 101 is in the closed state, the maintenance personnel do not press the button 304 in the pressing module 104. At this time, the button 304 in the pressing module 104 does not exert downward pressure, the button 304 contacts the curved surface structure of the locking pin 303 but does not produce a kinematic pair relationship, and the return spring 305 is in an extended state. Under the action of the return spring 305 in the extended state, the locking pin 303 remains in a state of extending out of the fixed plate 301, while the locking pin 303 is inserted into the lock hole in the step cover 101, so as to keep the step cover 101 covering the opening of the pedal body 105, that is, to close the maintenance window of the heavy vehicle.

[0064] Furthermore, when the push-type locking system on the vehicle needs to be changed from a closed state to an open state, that is, when the step cover 101 is changed from a closed state to an open state, the maintenance personnel presses the button 304 in the pressing module 104. At this time, the button 304 in the pressing module 104 exerts pressure downward under the force output by the maintenance personnel, and the button 304 contacts the curved surface structure of the lock pin 303 and generates a kinematic pair relationship, so that the curved surface structure of the lock pin 303 retreats under the action of the lower part of the button 304, and the return spring 305 is in a compressed state under the action of the curved surface structure of the lock pin 303. At this time, the lock pin 303 moves toward the direction of the fixed plate 301 under the drive of the curved surface structure. The step cover 101 is retracted and the locking pin 303 withdraws from the corresponding locking hole in the step cover 101. At this time, the maintenance personnel can release the button 304. In the absence of the locking pin 303 being fixed to the corresponding locking hole in the step cover 101, the step cover 101 is supported by the pin shaft and the elastic force of the Z-shaped spring 103, and the step cover 101 is pushed away from the opening of the pedal body 105 to realize the rotation and opening of the step cover 101. The Z-shaped spring 103 and the fixed bracket 102 are contacted to realize the self-limiting of the step cover 101, so that the step cover 101 is rotated and opened to an angle of ninety degrees, that is, the maintenance window of the heavy vehicle is opened to a preset angle. At this time, the Z-shaped spring 103 is in an expanded state.

[0065] Furthermore, when the push-type locking system on the vehicle needs to be switched from an open state to a closed state, that is, when the step cover 101 is switched from an open state to a closed state, the maintenance personnel presses the button 304 in the pressing module 104. At this time, the button 304 in the pressing module 104 exerts pressure downward under the force output by the maintenance personnel, and the button 304 contacts the curved surface structure of the lock pin 303 and generates a kinematic pair relationship, so that the curved surface structure of the lock pin 303 retreats under the action of the lower part of the button 304, and the return spring 305 is in a compressed state under the action of the curved surface structure of the lock pin 303. At this time, the lock pin 303 retracts toward the direction of the fixed plate 301 driven by the curved surface structure, and the maintenance personnel After the staff applies external force to cover the step cover 101 on the opening of the pedal body 105, the Z-shaped spring 103 is in a compressed state at this time, and the maintenance personnel releases the button 304. At this time, the button 304 contacts the curved surface structure of the locking pin 303 and produces a kinematic pair relationship, and the return spring 305 is in an extended state. Under the action of the return spring 305 in the extended state, the curved surface structure of the locking pin 303 drives the button 304 to reset, and the locking pin 303 extends in the direction away from the fixed plate 301. At the same time, the locking pin 303 is inserted into the locking hole in the step cover 101 to keep the step cover 101 covering the opening of the pedal body 105. At this time, the maintenance personnel can release the step cover 101 to close the opened maintenance window.

[0066] The push-type locking system on the vehicle provided in the embodiment of the present application controls the button on the push module so that the locking pin in the push module disengages from the locking hole on the step cover plate, and opens the step cover plate under the thrust generated by the Z-shaped spring changing from a compressed state to an extended state, thereby realizing opening the maintenance window of the heavy-duty vehicle through the step cover plate, thereby avoiding the defects of difficult operation and opening jamming caused by the existing interference fit scheme, and further facilitating the operation of maintenance personnel when repairing commercial vehicles, thereby improving the maintenance efficiency of heavy-duty commercial vehicles.

[0067] The specific structure of the push module 104 in the push-type locking system on the vehicle will be further described in detail below.

[0068] Figure 4 Schematic diagram of the pressing module structure provided in the embodiment of the present application Figure 2 ,like Figure 4 As shown, a guide structure is also provided in the fixed plate 301 in the pressing module 104, and a track 402 is provided in the guide structure. The button 304 slides in the track 402, and the extension direction of the track 402 is perpendicular to the movement direction of the locking pin 303, so that when the button 304 is in a pressed state, it slides according to the track 402 to limit the up and down movement of the button 304.

[0069] The guide structure includes limiting structures 401 arranged on both sides of the fixed plate. The two limiting structures form a track, so that when the locking pin 303 is telescopic, it slides along the track formed by the limiting structures 401 to limit the left and right movement of the locking pin 303.

[0070] Furthermore, when the maintenance personnel presses the button 304 in the pressing module 104, that is, the button 304 is in a pressed state, the button 304 in the pressing module 104 slides downward along the track 402 under the force output by the maintenance personnel, wherein the upper side of the button 304 is provided with a sliding portion that cooperates with the track 402, and the upper part of the button 304 and the lower part of the button 304 are integrally formed, and the sliding portion of the button 304 slides in cooperation with the track 402, so that the lower part of the button 304 contacts the curved surface structure of the locking pin 303 and generates a kinematic pair relationship, so that the curved surface structure of the locking pin 303 retreats under the action of the lower part of the button 304, that is, at this time, the locking pin 303 retracts toward the direction of the fixed plate 301 under the drive of the curved surface structure, and the locking pin 303 retreats with the cooperation of the track formed by the limiting structure 401.

[0071] Furthermore, when the maintenance personnel releases the button 304 in the pressing module 104, the button 304 in the pressing module 104 does not exert downward pressure, that is, the button 304 is in the initial state, the button 304 in the pressing module 104 does not exert downward pressure, and the reset spring 305 is in an extended state. Under the action of the reset spring 305 in the extended state, the button 304 contacts the curved surface structure of the locking pin 303 and produces a kinematic pair relationship. The button 304 is subjected to an upward force, and the button 304 slides upward through the cooperation between the sliding part of the button 304 and the track 402. At the same time, under the action of the reset spring 305 in the extended state, the locking pin 303 moves forward under the curved surface structure. That is, at this time, the locking pin 303 is driven by the curved surface structure and extends in a direction away from the fixed plate 301 through the cooperation of the track formed by the limiting structure 401.

[0072] The embodiment of the present application provides a push-type locking system on a vehicle, by pressing a button on a push module, the button slides downward with the cooperation of a guide structure, so that under the action of the curved surface structure of the lower part of the button and the lock pin, the lock pin is separated from the lock hole on the step cover plate, at this time, the button is released, and under the thrust generated by the Z-shaped spring changing from a compressed state to a telescopic state, the step cover plate rotates open, and the inspection window of the heavy vehicle is opened through the step cover plate; and when the inspection window needs to be closed, the button and the step cover plate are pressed again, and when the lock hole on the step cover plate is aligned with the lock pin of the push module, the button is released, and under the action of the reset spring in the extended state and the curved surface structure of the lock pin, the lower part of the button slides upward with the cooperation of the guide structure, and the button is reset to realize the closing of the flip step cover plate, and the step cover plate covers and closes the inspection window of the heavy vehicle, thereby avoiding the defects of difficult operation and opening and closing jamming caused by the existing interference fit scheme, and then when the commercial vehicle is inspected, it is convenient for the maintenance personnel to operate, and the maintenance efficiency of the heavy commercial vehicle is improved.
