Description

Technical Field

[0001] The invention relates to the technical field of automobile supplies, in particular to a safety insurance device for an inner handle of an automobile door. Background Art

[0002] There is an inner handle inside the car door, and the closed door can be opened by pulling the inner handle. Considering the safety of the car during driving, the car manufacturer will restrict the opening method of the inner handle. For example, some brands of cars need to pull the inner handle twice to open the door during driving. This opening method fully considers various emergencies and effectively balances safety. When the person in the car accidentally pulls the inner handle once, it is a case of accidental touch, and the driver can detect it in time and make effective disposal. When the car has an accident, the people in the car need to escape urgently, and they only need to pull the inner handle twice in succession to open the door for escape. For another example, some brands of cars only need to pull the inner handle once to open the door during driving. The starting point for considering safety is: when the car has an accident, it is necessary to ensure that the inner handle can be pulled once to escape quickly.

[0003] However, the above-mentioned method of pulling the inner handle twice to open the door still has disadvantages. If there are young children sitting in the back seat of the car, they do not have a high sense of safety and will still pull the inner handle twice to open the door, which brings safety hazards to the normal driving of the car. Although car manufacturers usually install child safety locks on the doors, when the child safety locks are activated, the door will not be opened by pulling the inner handle no matter how much, and the door can only be opened by pulling the outer handle from the outside of the car, but this method brings great safety hazards to the escape of people in the car.

[0004] Therefore, it is necessary to develop a safety insurance device for the inner handle of a car door, especially for young children who have no safety awareness, which can solve the problem of accidentally touching the inner handle and solve the problem of emergency escape. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a safety insurance device for the inner handle of a car door, mainly for young children who have no safety awareness, which can solve the problem of accidentally touching the inner handle and solve the problem of emergency escape.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] A safety device for an inner handle of a car door, comprising: a base, a blocking plate with a notch, and an elastic member;

[0008] The blocking plate is provided with a plug-in structure, the base is provided with a plurality of elastic arms, the plurality of elastic arms surround to form a sleeve cavity, and the plug-in structure is rotatably plugged into the sleeve cavity;

[0009] Each of the elastic arm bars is provided with a convex edge on one side away from the base, the convex edge has an anti-slip surface facing the base, and an anti-rotation gap is formed between two adjacent convex edges; the plug-in structure has a supporting surface, and a plurality of anti-rotation protrusions are arranged around the supporting surface;

[0010] The elastic member is used to provide elastic force for the plug-in structure, so that the abutting surface approaches the anti-slip surface, thereby enabling the anti-rotation protrusion to be restrained in the anti-rotation gap;

[0011] The blocking plate is pressed to compress the elastic member so that the abutting surface is away from the anti-slip surface, thereby allowing the anti-rotation protrusion to be separated from the anti-rotation gap.

[0012] In one of the embodiments, the safety device for the inner door handle of a vehicle further comprises an adhesive pad disposed on the base.

[0013] In one embodiment, the elastic member is a cylindrical spring, which is accommodated in the sleeve cavity. The cylindrical spring is in a compressed state and is located between the plug-in structure and the base.

[0014] In one embodiment, the base and the plurality of elastic arms are integrally injection molded.

[0015] In one embodiment, the blocking plate and the plug-in structure are integrally injection molded.

[0016] In one of the embodiments, the convex edge has an inclined guide surface disposed away from the base.

[0017] In one of the embodiments, the anti-rotation protrusion has a rotation auxiliary inclined surface.

[0018] The safety device for the inner handle of a car door of the present invention is mainly aimed at young children who have no safety awareness. It can solve the problem of accidentally touching the inner handle and the problem of emergency escape. It can be seen that once an accident occurs and an emergency escape is required, the safety device is very easy to unlock. The adult passengers in the car can press the blocking plate and rotate it to make the inner handle handle in a state that can be pulled, and even the entire safety device attached to the car door can be directly pulled off by force.

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] like Figure 1 and Figure 2 As shown, the present invention discloses a safety device 10 for an inner handle of a vehicle door, comprising: a base 100 , a blocking plate 200 with a notch 210 , and an elastic member 300 .

[0032] The blocking plate 200 is provided with a plug-in structure 400 (such as Figure 3 As shown), the base 100 is provided with a plurality of elastic arms 500 (as shown Figure 3 As shown), a plurality of elastic arms 500 surround and form a sleeve cavity 501 (as shown Figure 2 As shown), the plug-in structure 400 can be rotatably plugged into the sleeve cavity 501.

[0033] Each elastic arm 500 is provided with a convex edge 510 (eg, Figure 5 As shown), the flange 510 has an anti-slip surface 511 (as shown) disposed facing the base 100 Figure 4 As shown), an anti-rotation gap 502 is formed between two adjacent protrusions 510 (as shown Figure 5 The plug-in structure 400 has a supporting surface 410 (as shown); Figure 6 ), a plurality of anti-rotation protrusions 420 are disposed around the abutting surface 410 (as shown in FIG. Figure 6 shown).

[0034] like Figure 3 and Figure 4As shown, the elastic member 300 is used to provide elastic force for the plug-in structure 400, so that the abutting surface 410 approaches the anti-slip surface 511, and then the anti-rotation protrusion 420 can be bound in the anti-rotation gap 502. In this embodiment, the elastic member 300 is a cylindrical spring, which is accommodated in the sleeve cavity 501. The cylindrical spring is in a compressed state and is located between the plug-in structure 400 and the base 100. Of course, the elastic member 300 can also be in the form of a tension spring, and other structures need to be adaptively modified to achieve the purpose of the elastic member 300 providing elastic force for the plug-in structure 400.

[0035] The blocking plate 200 is pressed to compress the elastic member 300 , so that the abutting surface 410 is separated from the anti-slip surface 511 , thereby allowing the anti-rotation protrusion 420 to be separated from the anti-rotation gap 502 .

[0036] Next, the method of using the safety device 10 for the inner handle of a vehicle door of the above structure is described:

[0037] like Figure 7 and Figure 8 As shown, the assembled safety device 10 for the inner handle of the automobile door is fixed near the inner handle 20 of the automobile door; when fixing, it is preferred to fix the base 100 near the inner handle of the automobile door in an adhesive manner, and when it is not needed, the entire safety device can be easily removed without causing damage to the door; in this embodiment, the safety device 10 for the inner handle of the automobile door also includes an adhesive pad 600 (such as Figure 1 and Figure 2 As shown), for example, 3M glue is used to achieve bonding; of course, in other embodiments, the base 100 can also be fixed near the inner handle of the car door by negative pressure adsorption;

[0038] like Figure 7 As shown, after the safety device is fixed near the inner handle of the car door, the blocking plate 200 is rotated so that the other parts of the blocking plate 200 except the notch 210 correspond to the inner handle. The inner handle cannot be pulled due to being blocked by the blocking plate 200, and the car door cannot be opened;

[0039] like Figure 8 As shown, when the vehicle door needs to be opened, the blocking plate 200 is pressed and rotated so that the notch 210 of the blocking plate 200 corresponds to the inner handle. In this way, the inner handle has room to move, and the vehicle door is opened by pulling the inner handle.

[0040] Next, the working principle of the safety device 10 for the inner handle of a vehicle door of the above structure is described:

[0041] To realize the rotation of the blocking plate 200, firstly, an axial force needs to be applied to the blocking plate 200 along the axial direction, so that the anti-slip surface 511 and the abutting surface 410 are separated from each other, and then the anti-rotation protrusion 420 is separated from the restraint of the anti-rotation gap 502, so that the blocking plate 200 has the basic conditions for rotation;

[0042] For young children, their intelligence is not fully developed, and they do not have the ability to apply axial force to the blocking plate 200 and then rotate it. In addition, since the elastic member 300 will apply a strong axial elastic force to the blocking plate 200, young children have less strength and it is very difficult to overcome the axial elastic force.

[0043] Furthermore, in the present invention, there is a technical problem that needs to be solved: in order not to damage the vehicle door, the base 100 is mainly fixed to the vehicle door by pasting, and the adhesive force is relatively small. For some passengers who are not familiar with the structure of the safety device of the present invention, they may forcibly rotate the blocking plate 200. At this time, the base 100 is very likely to fall off. If a new adhesive pad is not replaced, it will become difficult to achieve a stable bond again later.

[0044] In order to solve this technical problem, the present invention also has such a design concept: an anti-rotation gap 502 is formed between two adjacent convex edges 510, a plurality of anti-rotation protrusions 420 are arranged around the abutting surface 410, and the anti-rotation protrusions 420 have a rotation auxiliary inclined surface 421 (such as Figure 6 As shown in the figure); in this way, in order to cause the blocking plate 200 to rotate, it is not necessary to first apply axial force to the blocking plate 200. For some young children or adult passengers with greater strength, the blocking plate 200 can also be rotated within a certain range. Therefore, the safety device fixed to the vehicle door in the form of an adhesive can be protected to prevent the safety device from easily falling off the vehicle door due to strong external force. It is worth emphasizing that for some young children or adult passengers with greater strength, even if they have a certain ability to rotate the blocking plate 200, during the rotation of the blocking plate 200, a "clicking" collision sound will occur between the anti-rotation protrusion 420 and the anti-rotation gap 502, which is similar to a sound alarm. Other adult passengers in the car can discover and stop it in time. In this way, a better balance can be found between preventing product damage and safety insurance.

[0045] In the present invention, the base 100 and the plurality of elastic arms 500 are integrally injection molded to obtain a semi-finished product A, the blocking plate 200 and the plug-in structure 400 are integrally injection molded to obtain a semi-finished product B, the elastic member 300 is loaded, and the semi-finished product A and the semi-finished product B are combined with each other, so that the finished product of the safety device can be quickly obtained. In addition, the structural design of the present invention fully considers the possibility and feasibility of the actual production of the product, the base 100 and the plurality of elastic arms 500 are integrally injection molded, and the blocking plate 200 and the plug-in structure 400 are integrally injection molded, which is also easy to open a mold.

[0046] In the present invention, the flange 510 has an inclined guide surface 512 (eg, Figure 5 As shown, during the process of assembling the semi-finished product A and the semi-finished product B, under the guidance of the inclined guide surface 512, a plurality of elastic arm rods 500 will undergo slight elastic deformation so that the plug-in structure 400 can easily enter the sleeve cavity 501. After the plug-in structure 400 enters the sleeve cavity 501, the plurality of elastic arm rods 500 restore the deformation and lock the plug-in structure 400 to prevent it from falling off.

[0047] In summary, the safety device 10 for the inner handle of a car door of the present invention is mainly aimed at young children who have no safety awareness. It can solve the problem of accidentally touching the inner handle and the problem of emergency escape. It can be seen that once an accident occurs and an emergency escape is required, the safety device is very easy to unlock. The adult passengers in the car can press the blocking plate 200 and rotate it, so that the inner handle is in a state that can be pulled, and even the entire safety device attached to the car door can be directly pulled off by force.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
