Description

Technical Field

[0001] The present invention relates to the technical field of truck interiors, and particularly to a safety overhead cabinet for trucks. Background Art

[0002] In recent years, with the development of the economy, people's demand for automobiles has not only been a means of transportation, but also the safety and comfort of automobiles have become important criteria for people to buy cars.

[0003] Many truck drivers often take the truck as their home during business trips. Therefore, the practicality and effectiveness of the corresponding products in the vehicle will be particularly important.

[0004] In the overhead cabinet in front of the truck cab, it is used for the driver to place daily necessities, and is closed by a large cabinet door. The cabinet door is hinged on the overhead cabinet. In order to prevent the cabinet door from closing under the influence of gravity after being opened, a gas spring is used to support between the cabinet door and the overhead cabinet, so that the cabinet door can be in an open state. However, the side wall of the overhead cabinet is thin and soft in texture. After opening and closing the cabinet door many times, the side wall of the overhead cabinet is easily torn by the acting force of the gas spring. On the one hand, it causes property losses to the driver, and on the other hand, it may also cause the items in the overhead 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 deficiencies in the prior art that the side wall of the overhead cabinet is thin and soft in texture, and after opening and closing the cabinet door many times, the side wall of the overhead cabinet is easily torn by the acting force of the gas spring, which causes property losses to the driver on the one hand, and on the other hand, it may also cause the items in the overhead cabinet to fall and injure the driver, posing a safety hazard, the present invention provides a safety overhead cabinet for trucks.

[0006] The technical solution adopted by the present invention to solve its technical problems is: A safety overhead cabinet for trucks, including a cabinet body and a flip cover. An opening is provided on the front side of the cabinet body. The flip cover is arranged on the front side of the cabinet body. A rotating shaft for rotatably connecting with the flip cover is provided at the upper end of the cabinet body. A locking rod is provided between the side wall of the cabinet body and the flip cover. The locking rod includes 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 side wall of the cabinet body, and the other end is hinged to the 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 the side of the first locking arm, the connecting block and the second locking arm away from the opening of the cabinet body. The cross sections of the first elastic sheet and the second elastic sheet are arc-shaped.

[0007] The lift cover is connected to the cabinet body through a rotating shaft, and the lift cover opens and closes the top cabinet along the rotating shaft; when the lift cover is fully opened, the axes of the first locking arm, the connecting block and the second locking arm coincide. The first elastic sheet straightens to support the hinge point between the first locking arm and the connecting block, and the second elastic sheet straightens to support the hinge point between the second locking arm and the connecting block. The first elastic sheet and the second elastic sheet are cut from a steel tape measure. The first elastic sheet and the second elastic sheet have a certain rigid supporting ability in the straightened state. When it is necessary to close the lift cover, the first elastic sheet and / or the second elastic sheet is broken to make it bend and deform. After deformation, the first elastic sheet and the second elastic sheet lose the supporting force and have a relatively small elastic force. The first locking arm, the connecting block and the second locking arm slowly fold along the hinge point, which can also prevent the lift cover from closing quickly and has a certain buffering effect. When the first elastic sheet and the second elastic sheet are bent, the elastic force is small, and only when they are fully straightened can they form a rigid support. The rigid support of the elastic sheet ensures that the lift cover maintains the open state. During the opening and closing process of the lift cover, the acting force of the second locking arm on the side wall of the cabinet body is only the tiny elastic force of the first elastic sheet and the second elastic sheet. The side wall of the cabinet body will not be torn when the lift cover is opened and closed. The first elastic sheet and the second elastic sheet are arranged on the side of the first locking arm, the connecting block and the second locking arm away from the cabinet opening to prevent the driver's hand from being scratched by the first elastic sheet and the second elastic sheet.

[0008] Further, in order to ensure the normal use of the first elastic sheet and the second elastic sheet, one end of the first elastic sheet and the second elastic sheet is provided with a waist-shaped hole arranged along the length direction, and the other end is provided with a round hole, and screws are inserted through the waist-shaped hole and the round hole.

[0009] Further, a U-shaped unlocking rod is provided at the opening of the cabinet body. The middle positions of the two side rods of the U-shaped unlocking rod are hinged to the side wall of the cabinet body. The two ends of the U-shaped unlocking rod are provided with push rods extending towards the connecting block, and the bottom rod of the U-shaped unlocking rod is arranged above the bottom wall of the cabinet body.

[0010] When the driver needs to close the lift cover, he gropes for the bottom rod of the U-shaped unlocking rod and pulls it outwards. The U-shaped unlocking rod swings along the hinge point, and the push rods at both ends squeeze the connecting block, simultaneously breaking the first elastic sheet and / or the second elastic sheet in the two locking rods on both sides to make them bend and deform, so as to close the lift cover.

[0011] Further, in order to prevent the side wall of the cabinet body from being torn, a strengthening bracket is provided on the outer wall surface of the cabinet body. One end of the strengthening bracket is hinged to the lower end of the second locking arm through a fixing pin, and the other end is hinged to the middle position of the U-shaped unlocking rod through a fixing pin.

[0012] Further, in order to prevent the U-shaped unlocking rod from turning outwards, a limiting block for restricting the movement range of the U-shaped unlocking rod is provided on the side wall of the cabinet body. The part of the U-shaped unlocking rod below the hinge point is heavier than the part above the hinge point. Generally, the push rod of the U-shaped unlocking rod will abut against the connecting block. In order to prevent the driver from accidentally operating and causing the U-shaped unlocking rod to turn outwards to the outside of the cabinet body, a limiting block is used to restrict the movement range of the U-shaped unlocking rod.

[0013] Further, in order to ensure stable connection between the lid and the cabinet body when the lid is closed, an installation groove is provided at one end of the lid far from the rotating shaft. A push-button fixing hook is slidably arranged in the installation groove. A return spring is arranged between the push-button fixing hook and the bottom of the installation groove. A connection hole matching with the push-button fixing hook is provided at the bottom of the cabinet body.

[0014] Further, reinforcing ribs recessed towards the inside of the cabinet body are provided on the side wall of the cabinet body.

[0015] The beneficial effects of the present invention are as follows: A safety overhead cabinet for a truck provided by the present invention uses a locking rod arranged between the cabinet body and the lid to support the lid. After the locking rod is straightened by the elastic sheet, it has rigid support, and after being bent, it has a small elastic force for buffering, so that the acting force of the locking rod on the side wall of the cabinet body is small during the opening and closing process of the lid, avoiding tearing of the side wall of the cabinet body and prolonging the service life of the overhead cabinet.
