[0026] Embodiment

[0027] As Figures 1-4 shown, an anti-collision protection device for an automobile door lock housing proposed by the present utility model includes a car door 1, a window 2 is provided on the car door 1, and further includes a door lock assembly 11 provided in the housing of the car door 1. An installation cavity 5 is provided in the car door 1, the door lock assembly 11 is located in the installation cavity 5, and the door lock assembly 11 includes a handle 3 provided on the outer side of the car door 1 and a button 4 provided on the inner side of the car door 1.

[0028] In this embodiment, the protection component includes an anti-collision plate 6 located inside the door 1 housing for protecting the door lock assembly 11. The anti-collision plate 6 is arranged on one side of the door 1 housing close to the handle 3. The anti-collision plate 6 is a multi-arc panel body formed integrally. The anti-collision plate 6 is made of aluminum alloy. The anti-collision plate 6 includes a first arc surface 61, a second arc surface 62, and a third arc surface 63. The anti-collision plate 6 with a multi-arc panel body makes the impacted surface change from a straight line to a curve, which can more effectively disperse the impact force over a larger area, thereby exerting better impact resistance and realizing anti-collision protection for the door lock assembly 11.

[0029] Among them, the convex surfaces of the first arc surface 61 and the third arc surface 63 face the side of the door 1 close to the handle 3, and the convex surface of the second arc surface 62 faces the side of the door 1 away from the handle 3. The center point of the second arc surface 62 is on the same horizontal plane as the door lock assembly 11. When impacted, the first arc surface 61 and the third arc surface 63 are first impacted to provide anti-collision protection for the door lock assembly 11.

[0030] In addition, the first arc surface 61, the second arc surface 62, and the third arc surface 63 are arranged in sequence from top to bottom. A first support rod 9 and a second support rod 10 are fixedly installed between the concave surfaces of the first arc surface 61 and the third arc surface 63 and the installation cavity 5 respectively. The first support rod 9 and the second support rod 10 are arranged in a V shape. The first support rod 9 and the second support rod 10 arranged in a Y shape can improve the support ability for the anti-collision plate 6.

[0031] Among them, a fixed plate 12 is fixedly installed on one side of the inner wall of the installation cavity 5 close to the button 4. The first support rod 9 and the second support rod 10 are both fixedly installed on the fixed plate 12 through bolts, which is convenient for the staff to load and unload. A reinforcing plate 7 is fixedly installed between each group of the first support rod 9, the second support rod 10 and the anti-collision plate 6. A cavity 8 is formed inside the reinforcing plate 7. The cavity 8 arranged inside the reinforcing plate 7 enables the reinforcing plate 7 to deform when impacted, thereby absorbing more impact force and further providing anti-collision protection for the door lock assembly 11.

[0032] Working principle: During the working process of the present utility model, when the door lock assembly 11 is impacted, the anti-collision plate 6 is first impacted. The first arc surface 61, the second arc surface 62, and the third arc surface 63 of the anti-collision plate 6 make the impacted surface of the anti-collision plate 6 change from a straight line to a curve, effectively increasing the force-bearing area and dispersing the impact force over a larger area, thereby improving the anti-collision protection effect of the anti-collision plate 6. At the same time, the cavity 8 arranged inside the reinforcing plate 7 enables the reinforcing plate 7 to deform when impacted, thereby absorbing more impact force and further providing anti-collision protection for the door lock assembly 11. While realizing anti-collision protection for the door lock assembly 11, the weight of the anti-collision plate 6 is reduced and the production cost is lowered.

[0033] In the above embodiments, the door lock assembly 11 is a prior art and will not be elaborated here. The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
