[0002] In recent years, with the development of the economy, people's demand for cars is no longer just a means of transportation. The safety and comfort of cars have also become important criteria for people to consider when buying a car.

[0003] Many truck drivers often use their trucks as their home while on business, so the practicality and effectiveness of the corresponding products in the truck will be particularly important.

[0004] The upper cabinet on the front side of the truck cab is used for the driver to place daily necessities and is closed with a large cabinet door. The cabinet door is hinged on the upper cabinet. In order to prevent the cabinet door from being closed due to gravity after opening, a gas spring is used between the cabinet door and the upper cabinet to support the cabinet door so that it can be in an open state. However, the side walls of the upper cabinet are thin and soft. The side walls of the upper cabinet are easily torn by the force of the gas spring after the cabinet door is opened and closed many times, which not only causes property loss to the driver, but also causes the items in the upper cabinet to fall and injure the driver, posing a safety hazard. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the prior art that the side walls of the top cabinet are thin and soft, and the cabinet door is opened and closed many times, so that the side walls of the top cabinet are easily torn by the force of the gas spring, which on the one hand causes property loss to the driver, and on the other hand may cause the items in the top cabinet to fall and injure the driver, thus posing a safety hazard. The present invention provides a safety top cabinet for trucks.

[0006] The technical solution to be adopted by the present invention to solve its technical problems is: a safety top cabinet for trucks, comprising a cabinet body and a flip cover, the cabinet body is provided with an opening on the front side, the flip cover is arranged on the front side of the cabinet body, the upper end of the cabinet body is provided with a rotating shaft rotatably connected to the flip cover, a locking rod is provided between the cabinet body side wall and the flip cover, the locking rod comprises a first locking arm, a second locking arm and a connecting block, one end of the first locking arm is hinged to the flip cover, and the other end is hinged to one end of the connecting block, one end of the second locking arm is hinged to the cabinet side wall, and the other end is hinged to a side of the connecting block away from the first locking arm, a first elastic sheet is connected between the first locking arm and the connecting block, one end of the first elastic sheet is fixedly connected to the connecting block, and the other end is slidably connected to the first locking arm, a second elastic sheet is connected between the second locking arm and the connecting block, one end of the second elastic sheet is fixedly connected to the connecting block, and the other end is slidably connected to the second locking arm, the first elastic sheet and the second elastic sheet are arranged on a side of the first locking arm, the connecting block and the second locking arm away from the cabinet opening, and the cross-section of the first elastic sheet and the second elastic sheet is arc-shaped.

[0007] The flip cover is connected to the cabinet body through a rotating shaft, and the flip cover opens and closes along the rotating shaft to open or close the top cabinet; when the flip cover is fully opened, the axes of the first locking arm, the connecting block and the second locking arm coincide, the first elastic sheet is straightened to support the hinge point between the first locking arm and the connecting block, and the second elastic sheet is straightened to support the hinge point between the second locking arm and the connecting block; the first elastic sheet and the second elastic sheet are formed by cutting off a steel measuring tape, and the first elastic sheet and the second elastic sheet have a certain rigid supporting capacity in the straightened state; when it is necessary to close the flip cover, the first elastic sheet and / or the second elastic sheet are broken to bend and deform them, and the deformed first elastic sheet and the second elastic sheet lose their supporting force and have a relatively small elastic force, and the first locking arm, the connecting block and the second locking arm are slowly folded along the hinge point, which can also prevent the flip cover from closing quickly and have a certain buffering effect. The first elastic sheet and the second elastic sheet have little elastic force when bent, and only when they are fully straightened can they form a rigid support, and the rigid support of the elastic sheet ensures that the flip cover remains in the open state; during the opening and closing process of the flip cover, the force exerted by the second lock arm on the side wall of the cabinet is only the tiny elastic force of the first elastic sheet and the second elastic sheet, and the side wall of the cabinet will not be torn when the flip cover is opened and closed. The first elastic sheet and the second elastic sheet are arranged on the side of the first lock arm, the connecting block and the second lock arm away from the cabinet opening to prevent the driver's hands from being scratched by the first elastic sheet and the second elastic sheet.

[0012] Furthermore, in order to prevent the U-shaped unlocking lever from turning outward, a limit block for limiting the range of motion of the U-shaped unlocking lever is provided on the side wall of the cabinet. The portion below the hinge point of the U-shaped unlocking lever is heavier than the portion above the hinge point. Generally, the push rod of the U-shaped unlocking lever will be against the connection block. In order to prevent the driver from misoperating and causing the U-shaped unlocking lever to turn outward to the outside of the cabinet, a limit block is used to limit the range of motion of the U-shaped unlocking lever.

[0013] Furthermore, in order to ensure a stable connection between the flip cover and the cabinet body when the flip cover is closed, an installation groove is provided on the end of the flip cover away from the rotating shaft, a push-type fixing hook is slidably arranged in the installation groove, a return spring is provided between the push-type fixing hook and the bottom of the installation groove, and a connecting hole is provided at the bottom of the cabinet body to cooperate with the push-type fixing hook.

[0014] Furthermore, the cabinet side walls are provided with reinforcing ribs recessed toward the inner side of the cabinet.

[0015] The beneficial effects of the present invention are as follows: a safety top cabinet for a truck provided by the present invention adopts a locking rod arranged between the cabinet body and the flip cover to support the flip cover. The locking rod has a rigid support after being straightened by an elastic sheet, and has a small elastic force for buffering after being bent, so that the locking rod has a small force on the side wall of the cabinet body during the opening and closing of the flip cover, thereby avoiding tearing of the side wall of the cabinet body and extending the service life of the top cabinet.
