Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety, in particular to a vehicle safety door lock. Background Art

[0002] Forgetting to check the situation outside the car and opening the door rashly when getting out of the car can easily lead to tragedy. The Dutch door opening method can reduce the probability of this happening. The Dutch door opening method means that you always use the hand that is farther away from the door to open the door, thereby reducing the visual blind spot. Patent document CN220285527U provides a two-handed door opening mechanism for a car and its inner door handle structure. This solution completely transforms the vehicle door lock to achieve the purpose of two-handed door opening. However, it is not suitable for cars that are in use. Now a method is provided that can improve the door lock of existing cars in use, so as to achieve the purpose of two-handed door opening and reduce accidents. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a car safety door lock, which effectively solves the problem that the prior art cannot meet the ability to modify the doors of vehicles in use and is not suitable for vehicles in use.

[0004] The technical solution is as follows: it includes a door handle, wherein the right end of the handle is hinged with the door side panel, a clamping hole is opened at the right end of the handle, the clamping hole faces right, a clamping pin passes through the door side panel, the clamping pin corresponds to the clamping hole, an annular protrusion is provided at the end of the clamping pin away from the handle, a tension spring is connected between the annular protrusion and the door side panel, a wire wheel is provided on the side of the pin away from the handle, the wire wheel is rotatably installed on the door side panel, a torsion spring is installed between the center axis of the wire wheel and the door side panel; the wire wheel and the pin are connected by a steel wire rope, and when the wire wheel rotates, the steel wire rope can drive the pin to move to the right and disengage from the clamping hole.

[0005] Furthermore, in order to facilitate the rotation of the wire wheel, a rotating handle coaxially fixed with the wire wheel is provided on the door side panel.

[0006] Furthermore, in order to save space and for aesthetics, a recess adapted to the handle is provided on the door side panel, and the handle is placed in the recess.

[0007] The utility model has an ingenious structure and is based on the most commonly used vehicle door lock mechanism. It improves the door lock of the vehicle in use and achieves the purpose of opening the door with both hands, thereby reducing accidents and ensuring driving safety.

[0011] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0012] Depend on Figures 1 to 3 It is given that the utility model includes a handle 2 of a vehicle door 1, the right end of the handle 2 is hinged to the side panel of the vehicle door 1, a clamping hole is opened at the right end of the handle 2, the clamping hole faces right, a clamping pin 3 passes through the side panel of the vehicle door 1, the clamping pin 3 corresponds to the clamping hole, an annular protrusion is provided at the end of the clamping pin 3 away from the handle 2, a tension spring is connected between the annular protrusion and the side panel of the vehicle, a wire wheel 4 is provided on the side of the pin away from the handle 2, the wire wheel 4 is rotatably installed on the side panel of the vehicle door 1, a torsion spring is installed between the center axis of the wire wheel 4 and the side panel of the vehicle door 1; the wire wheel 4 and the pin are connected by a steel wire rope, and when the wire wheel 4 rotates, the steel wire rope can drive the pin to move to the right and disengage from the clamping hole.

[0013] In order to facilitate the rotation of the wire wheel 4, a rotating handle 5 coaxially fixed with the wire wheel 4 is provided on the side panel of the vehicle door 1.

[0014] In order to save space and for aesthetics, a pit matching the handle 5 is provided on the side panel of the vehicle door 1, and the handle 5 is placed in the pit.

[0015] It is worth noting that the present invention aims to modify the existing vehicle door locks in use, and is committed to achieving the purpose of opening the door with both hands at a low cost, reducing accidents and casualties.

[0016] When in use, when the person in the car gets off, the hand close to the door 1 rotates the handle 5, the handle 5 drives the wire wheel 4 to rotate, the wire wheel 4 drives the pin to move to the right through the wire rope and disengage from the clamping hole, at this time, the handle 2 is pulled normally, and the door 1 is opened.

[0017] During the above process, the personnel must turn sideways to complete the above actions, and turning sideways also forces the personnel in the car to observe the situations in front and behind.

[0018] The utility model has an ingenious structure and is based on the most commonly used vehicle door lock mechanism. It improves the door lock of the vehicle in use and achieves the purpose of opening the door 1 with both hands, thereby reducing accidents and ensuring driving safety.
