Fig. 9 is a schematic view of an embodiment of the ceiling handle of the present invention in an initial state; fig. 10 is a schematic view of an embodiment of the ceiling handle according to the present invention in a use state. It is understood that the initial state refers to a position state (the elastic member is in a reset position) of the ceiling handle 1 when not in use, i.e., when not subjected to a tensile force. As shown in fig. 9 and 10, the roof handle 1 is fixed to the vehicle body by fixing the base plate 11 and a vehicle body metal plate (not shown) to each other with a base plate screw 111. Since the decorative panel body 31 of the ceiling handle 1 is attached to the ceiling, only the portion below the decorative panel 30 is exposed in the cab of the ceiling handle 1, and the entire appearance is simplified.

As shown in fig. 9, when the ceiling handle is in the initial state, only the handle portion 23 of the ceiling handle 1 protrudes from the ceiling, and the overall appearance is simple and occupies a very small space. When the user needs to use the ceiling handle 1, the user can hold the handle portion 23 and pull downward and adjust to a comfortable position, as shown in fig. 10. In addition, because the cladding has soft glue layer 24 and PU layer 25 on the handle body 20, ceiling handle 1 can provide better hand comfort level, and then promotes user's use and experiences.

Referring to fig. 1 to 10, it can be understood that when a pulling force is applied to the handle portion 23, the first and

second connection portions

21 and 22 move along with the handle portion 23 and partially protrude from the first and

second chambers

12 and 13, respectively. Meanwhile, the first rack 211 on the first connecting portion 21 drives the first gear 121 to rotate, and since the first spring 122 on the first gear 121 is stopped by the first stopping shaft 123, the first spring 122 can convert kinetic energy into elastic potential energy and store the elastic potential energy. Similarly, the second rack 221 of the second connecting portion 22 drives the second gear 131 to rotate, and converts the kinetic energy into elastic potential energy to be stored in the second spring 132. In addition, the first and

second grooves

212 and 222 limit the travel of the ceiling handle 1 to move up and down to ensure reliable movement of the ceiling handle 1. In this stroke, the user can freely control the position that ceiling handle 1 pulled out, is favorable to satisfying different demands.

When the user releases the ceiling handle 1, that is, removes the pulling force applied to the handle portion 23, the elastic potential energy stored in the first spring 122 and the second spring 132 is released and converted into kinetic energy to respectively rotate the first gear 121 and the second gear 131, so that the downwardly extending portions of the first connecting portion 21 and the second connecting portion 22 are respectively returned to the first chamber 12 and the second chamber 13, thereby automatically returning the ceiling handle 1 to the initial position. In addition, the damper provided in the first chamber 12 can prevent the ceiling handle 1 from being returned too fast, thereby alleviating a return abnormal sound.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions can be made on the related technical features by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions will fall into the protection scope of the invention.
