Description

Technical Field

[0001] The invention belongs to the technical field of heavy truck bodies, and in particular relates to a switch operating device for a front cover of a heavy truck. Background Art

[0002] Because of the large size of the cab of a medium or heavy truck, three or more steps are generally required for the user to climb to the cab.

[0003] When it is necessary to open or close the heavy truck mask (hood), it is very inconvenient. For this reason, an operating mechanism is currently set in the cab to open or close the heavy truck mask. The heavy truck mask operating mechanism is usually set on the dashboard or floor of the cab. This structure can automatically open or close the heavy truck mask. However, because the operating mechanism is arranged in the cab, the cab is at a high height from the ground, resulting in a long distance for opening or closing the operating mechanism. The user is also required to climb the steps and lean into the cab to unlock the vehicle, then get off the vehicle and return to the front of the vehicle to open the heavy truck mask (hood), which is inconvenient to use. At the same time, the unlocking traction system (wire rope cable) needs to be connected from the inside of the cab to the front mask (hood), and its path is tortuous and the length is too long, which affects the system operation force and reliability.

[0004] In order to solve this technical defect, the existing technology arranges the operating mechanism for opening the heavy truck mask outside the cab, such as on the heavy truck mask (hood), etc. However, this method cannot achieve the anti-theft function when using conventional mechanical locks, and the security is poor. If an electronic lock is used, it is necessary to add electronic control equipment and wiring harnesses, resulting in poor economy. Summary of the invention

[0005] The object of the present invention is to provide a heavy truck front mask switch operating device to solve the above-mentioned defects existing in the current heavy truck mask operating mechanism being arranged in the cab or arranged outside the cab.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

The cable branch is fixed to a back bracket of the boarding step. The input end of the first cable is connected to the switch handle assembly from the back of the boarding step, and the output end of the first cable is connected to the cable branch.

[0008] Furthermore, a rectangular hole is provided on the boarding step on which the switch handle assembly is provided.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0027] Most of the components involved in the heavy truck front cover switch operating device of the present application are existing technologies, and their structures and functions have not been improved. The key to this technology is to install the switch handle assembly on the boarding step and cover it with the lower door trim.

[0028] like Figure 1 As shown, the heavy truck front cover switch operating device of the present application includes a switch handle assembly 9, a cable brancher 6, a first cable 7, a second cable 5, a third cable 2, a left locking mechanism 4, a right locking mechanism 1, a front flip shaft tube 3, a boarding step 8, and a lower door trim panel 10.

[0029] In the technical solution of the present application, the left locking mechanism 4 and the right locking mechanism 1 are both existing technologies, and there is no improvement in structure and function. They are respectively arranged on both sides of the front cover of the heavy truck for locking connection with the vehicle body. Because the locking mechanism is existing technology, therefore, in the present technical solution, the structure of the left locking mechanism and the right locking mechanism and the matching relationship with the front cover and the vehicle body of the heavy truck are not described in detail. Those skilled in the art are aware of this structure. It should be emphasized here that the shape and structure of the left locking mechanism and the right locking mechanism of the present application are exactly the same.

[0030] The front cover of the heavy truck can be unlocked from the vehicle body by means of the pulling rope connected to the left locking mechanism and the right locking mechanism, so that the front cover of the heavy truck can be opened conveniently for maintenance and other operations.

[0031] In the technical solution of this application, if Figure 1 , Figure 2As shown, the switch handle assembly 9 is arranged on the boarding step 8. Specifically, a rectangular opening is provided on the boarding step about 1400 mm from the ground, near the front mask of the heavy truck. The switch handle assembly is installed at the rectangular opening and is fixed to the boarding step 8 by installing claws 911 and screws 13 respectively. Such a position is just blocked by the lower door trim 10, that is, when the door 11 is closed, the switch handle assembly 9 is blocked. The switch handle assembly can only be operated when the door is opened. In the technical solution of the present application, a height of 1400 mm from the ground is set, which is in line with the height of Oriental people and can be operated without stretching or bending over too much.

[0032] In the technical solution of this application, if Figures 3 to 5 As shown, the switch handle assembly 9 includes a switch body 901 with a groove, a switch rocker 902 and a mounting claw 911. The four sides of the groove of the switch body are basically flat and are provided with mounting holes 904 for fixing the switch body to the boarding step using screws.

[0033] The switch seesaw 902 is connected to the switch body through the seesaw shaft 903. The switch seesaw includes a seesaw body and a seesaw 908 below. The upper surface of the seesaw body has a certain curvature. A recessed portion is provided on the upper surface of the seesaw body to form a switch operating point 905. By pressing the switch operating point, the seesaw body sinks and rotates around the seesaw shaft to realize the forward movement of the seesaw, thereby pulling the first cable.

[0034] A cable connector slot 909 is provided at the lower end of the seesaw; a cable protection tube slot 910 is provided at the lower part of the switch body, and the cable protection tube slot is connected to the interior of the switch body. A seesaw limit claw 907 is provided inside the switch body. One end of the first cable is connected to the cable connector slot after passing through the cable protection tube slot, and the other end of the first cable is connected to the cable brancher. An installation claw 911 is provided at the upper part of the outer side of the switch body. After the switch body with a groove is placed into the rectangular hole of the boarding step, the installation claw is inserted into the edge of the rectangular hole through an X-side push, and the rear end mounting hole is fixed to the reed nut of the step body mounting hole by a screw. In this application, the first cable is located at the back of the boarding step.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, the cable branch 6 of the present application is fixed on the back bracket 12 of the boarding step, the second cable 5 is respectively connected to the left locking mechanism 4 and the cable branch 6, and the third cable 2 is respectively connected to the right locking mechanism 1 and the cable branch 6. Whether the locking mechanism needs to be controlled in series or in parallel, this direction can be applied.

[0036] The above are preferred implementation modes of the present invention. The above show and describe the basic principles of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
