Description

Technical Field

[0001] The present invention relates to a mask protection mechanism, and more specifically, to a front mask protection mechanism for a light truck cab to be flipped. Background Art

[0002] Different from the large-angle flipping of heavy truck models, due to factors such as small engine horsepower and sufficient maintenance space in light truck models, the front masks of the cabs are designed to be non-removable. During the flipping process of the cab, the front mask is fixed to the cab and flips together with the cab. However, with the increasing demand for large horsepower from customers, in order to ensure the convenience of maintenance and the aesthetics of the overall vehicle exterior in some models, the mask needs to be designed to be removable. However, the awareness of light truck users to lift the front mask before flipping the cab is weak, and incorrect operation will lead to problems such as interference and damage between the front mask and the bumper.

[0003] In view of this, it is necessary to design a front mask protection mechanism for a light truck cab to be flipped that can meet the requirements. Summary of the Invention

[0004] An object of the present invention is to provide a front mask protection mechanism for a light truck cab to be flipped, which solves the problem that the mask interferes with and damages the bumper due to incorrect operation by light truck users who directly flip the cab without lifting the front mask.

[0005] The technical problems to be solved by the present invention are realized through the following technical solutions:

[0006] A front mask protection mechanism for a light truck cab to be flipped, comprising:

[0007] A mask, which is used to cover the front part of the cab and can be flipped relative to the vehicle body;

[0008] A vehicle body connection bracket, which is welded to the vehicle body;

[0009] A mask connection bracket, which is connected to the mask through a hinge and is used to transmit the movement of the mask;

[0010] A wire drawing assembly, which is clamped and fixed along the longitudinal beam of the vehicle body floor. One end of the wire drawing assembly is connected to the mask connection bracket, and the other end is connected to a lock hook through a lock hook fixing bracket. When the mask is opened, the mask connection bracket drives the lock hook and unlocks the first lock;

[0011] A lock plate fixing bracket, which is connected to a lock plate. The lock hook is connected to the lock plate fixing bracket through a return spring, and the return spring automatically resets the lock hook after the mask is closed;

[0012] The second lock handle and the third lock handle are used to normally lock the cab when the mask is closed and the first lock is locked, and to unlock the second lock and the third lock in sequence after the first lock is unlocked, so as to realize the flipping of the cab.

[0013] Preferably, in the above technical solution, the mask connection bracket and the hinge of the mask are fixed with a common hole, which is used to transmit the movement of the mask to the wire rope assembly, and the first lock is unlocked by pulling the lock hook through the wire rope assembly.

[0014] Preferably, in the above technical solution, the wire rope assembly is in transmission connection with the lock hook. When the mask is lifted, the wire rope assembly pulls the lock hook to move, so as to unlock the first lock of the cab, and then unlock the second lock and the third lock through the second lock handle and the third lock handle in sequence to realize the flipping of the cab; when the mask is closed, the first lock is in the locked state, and the second lock handle and the third lock handle of the cab cannot be unlocked, and the flipping of the cab is prohibited.

[0015] Preferably, in the above technical solution, the wire rope assembly is fixed to the vehicle body through a clamping structure, and its two ends are respectively connected to the mask connection bracket and the lock hook through a hinged manner to ensure the reliability of the movement transmission.

[0016] Preferably, in the above technical solution, the lock plate fixing bracket is fixedly welded to the lock plate, which is used to define the movement track of the lock hook.

[0017] Preferably, in the above technical solution, the lock hook fixing bracket is fixedly welded to the lock hook, which is used to link the lock hook and the wire rope assembly.

[0018] Preferably, in the above technical solution, when the mask is closed, the return spring drives the lock hook to reset, so that the first lock of the cab is locked again, realizing the linkage between the closing of the mask and the locking of the first lock.

[0019] Preferably, in the above technical solution, the vehicle body connection bracket is fixedly welded to the vehicle body sheet metal to serve as the fixed base point of the linkage mechanism.

[0020] A usage method of a front mask protection mechanism for the flipping of a light truck cab includes the following steps:

[0021] S1. Mask lifting: Lift the mask and transmit it to the wire rope assembly through the mask connection bracket;

[0022] S2. Linkage unlocking: The movement of the wire rope assembly pulls the lock hook, so that the lock hook moves away from the lock plate, realizing the unlocking of the first lock of the cab;

[0023] S3. Cab Flip: Operate the second lock handle and the third lock handle in sequence, and the cab starts to flip.

[0024] S4. Cab Lowering: Operate the second lock handle and the third lock handle to unlock, so that the cab lowers, and the second lock and the third lock automatically lock.

[0025] S5. Mask Closing: After the mask is closed, the return spring acts on the lock hook, causing it to return and re-lock with the lock plate.

[0026] The above technical solutions of the present invention have the following beneficial effects:

[0027] (1) In this application, the mechanical linkage mechanism is used to prevent misoperation. While adding a wire drawing assembly, the first lock handle is cancelled without increasing the cost. At the same time, by cancelling the first lock handle and adding a wire drawing assembly, the anti-error function with zero cost increase is realized, which has promotional value.

[0028] (2) This application successfully solves the technical problem in the field of the torsion bar flip of the light truck cab. For the flip-up mask model, due to the misoperation of the customer, the step of flipping the mask is missed and the cab is directly flipped, which causes damage to parts. It forcibly changes the user's operation habit, and at the same time does not involve cost changes, and there is no need to add redundant mechanisms such as additional alarms.

[0050] Furthermore, the vehicle body connecting bracket 2 is welded and fixed to the vehicle body sheet metal to serve as a fixed base point of the linkage mechanism.

[0051] How this application works:

[0052] (1) Existing cab flipping method: Currently, the flipping of the torsion bar cab of a light truck requires unlocking the first, second, and third lock handles of the cab in sequence before the cab can be flipped. Prior to this, the front hood must be lifted, which is also a step that users often miss.

[0053] (2) Cab flipping method of this mechanism: The main principle is to cancel the first lock handle of the cab, synchronize the unlocking action with the front cover lifting action through the wire drawing assembly to achieve linkage; when the user wants to flip the cab, he must first lift the front cover, and through the lifting action of the front cover, pull the first lock hook of the cab to unlock, and then unlock the second and third lock handles in sequence to achieve cab flipping; when the cab falls back, the second and third locks are locked normally, and after the mask is closed, the first lock is reset under the action of the reset spring at the lock hook. If the mask is not opened, the second and third locks cannot be unlocked and the cab cannot be flipped.

[0054] A method for using a flip-over front cover protection mechanism for a light truck cab comprises the following steps:

[0055] S1. Mask lifted upwards: Lift the mask 1, and transfer the movement to the wire drawing assembly 4 through the mask connecting bracket 3;

[0056] S2. Linkage unlocking: The movement of the wire drawing assembly 4 pulls the locking hook 10, causing the locking hook 10 to move away from the locking plate 11, realizing the unlocking of the first lock of the cab;

[0057] S3. Cab flipping: Operate the second lock handle 6 and the third lock handle 7 in sequence, and the cab starts to flip;

[0058] S4. Cab falling back: Operate the second lock handle 6 and the third lock handle 7 to unlock, causing the cab to fall back, and the second lock and the third lock are automatically locked;

[0059] S5. Mask closing: After the mask 1 is closed, the return spring acts on the locking hook 10, causing it to return to its original position and relock with the locking plate 11.

[0060] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration purposes and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
