In recent years, government agencies have often strongly advocated that general vehicle driving or passengers should pay attention to whether there is a rear car from the glass or the rear view mirror before opening the door. Although the government has been advocating for many years, the effect is still not good. There are still traffic accidents caused by driving or passengers accidentally opening the doors.

In order to avoid the above situation, the inventor has developed a two-stage safety door warning device such as the Republic of China patent number "M477969", which is installed on the door of the traffic vehicle. This safety is mandatory for two-stage opening of the door. The warning device comprises: a first stage module comprising: a sensing unit, which is mounted in a door of the door to transmit a start signal; the first warning unit is installed inside the traffic vehicle and receives the start signal To remind the user that the door detection unit is installed around the door to transmit a control signal when the door opening distance is greater than the distance threshold; and the lock control unit receives the control signal to control the opening of the door; And the second stage module comprises: a delay timing unit, which generates a warning signal and calculates a delay time, when the delay time is greater than the time threshold, the unlock signal is transmitted to the lock control unit; and the second warning unit is installed in the Around the outside of the traffic vehicle, receive warning signals to alert the followers; when the user wants to get off, he will touch When the door is pulled in, the first stage module is triggered to limit the opening distance of the door; the delay time is the actuation time of the first stage module, and when the delay timing unit transmits the unlocking signal, the door is restored. Act naturally.

However, the safety-enforced two-stage opening of the door warning device in the above patent case still has the following shortcomings:

1. The above patent case is an electronic type of operation, which relies entirely on electronic detection equipment in operation. When an abnormal situation occurs in the system, it cannot effectively avoid accidents.

In order to solve the problem of frequent accidents caused by the general vehicle driving or the passengers who did not have a rear car before opening the door. And the patent case is an electronic type of operation, which relies entirely on electronic detection equipment in operation. When an abnormal situation occurs in the system, it cannot effectively avoid the lack of accident.

The present invention is directed to a door opening prevention device for preventing an emergency door opening device for mounting between a vehicle body and a door, comprising: a retracting structure disposed on the vehicle body, the retracting structure comprising There is a retracting space, an elastic rotating shaft and a connecting belt, one end of the connecting belt is coupled to the elastic rotating shaft and is retracted in the retracting space, and the other side of the connecting belt is connected to the sliding door, and the elastic rotating shaft is Providing the connecting belt with an elastic restoring force, the connecting belt exhibiting a pull state or a retracted state as the door is opened or closed; a latching member having a casing and a clutch locking unit, the outer edge of the casing is provided a clutch-shaped ratchet, and the clutch locking unit is coupled to the elastic rotating shaft, and is provided with a pawl corresponding to the tooth-shaped ratchet; when the door is momentarily opened, the biasing force is greater than a predetermined weight unit, the clutch lock The pawl of the solid unit is subjected to centrifugal force to hook against the toothed ratchet, so that the elastic rotating shaft stops rotating, so that the connecting belt pulls the door so that it cannot be opened.

Wherein the clutch locking unit further comprises a weight and a limiting strip, the limiting strip is secured by the elastic force of a spring to maintain the pawl in an original position, and the weight is subjected to centrifugal force The pawl is pressed against the spring force of the spring to push out toward the toothed ratchet.

And the clutch locking unit further comprises an inductive limit protrusion, the inductive limit protrusion is in contact with the outer handle of the one door, and is raised/lowered by the opening/closing of the outer handle.

The anti-door emergency opening device of the present invention has the following effects:

1. Through the centrifugal force of the clamping element, the user can be prevented from quickly opening the door without pre-tightening, thereby causing accidents such as rear vehicle collision.

2. When the clamping force is greater than the preset gravity unit by the clamping element, only a slight door angle can be opened to avoid accidents.

3. By the action of the sensing limit protrusion, the user can not open the door smoothly without being affected by the click element when opening the outer handle, thereby achieving convenient operation.

In order to further explain the embodiment of the present invention for preventing the door emergency opening device, please refer to the first figure and the second figure first. The figure first illustrates the creation for mounting in a vehicle body (A And a pivoting end (C) between a door (B), the door emergency opening device (100) comprising: a retracting structure (1) having a frame body (11), the frame body (11) There is an elastic shaft (12) running through it, and a retracting space is defined around the elastic shaft (12). The retracting structure (1) further includes a connecting belt (13) having a first end and a second end, the first end connecting the elastic shaft (12) and being retracted In the retracting space, the second end connects the door (B). The connecting belt (13) exhibits a pull state or a retracted state as the door (B) is opened or closed. Preferably, the elastic shaft (12) provides an elastic restoring force of the connecting belt, thereby enabling the connecting belt (13) to freely assume the retracted state.

Please refer to the second to fourth figures, which shows a card component (2) having a casing (21) and a clutch locking unit (23). The housing (21) is recessed with an accommodating space (211), and is fitted with the outer casing (21) by an outer casing plate (22) to cover the accommodating space (211), and more particularly, the outer casing ( 21) The inner edge is provided with a toothed ratchet (212), and the outer casing (21) is coupled with the elastic rotating shaft (12) and moves with each other.

The clutch locking unit (23) is disposed in the accommodating space (211), and the clutch locking unit (23) has a turntable (231), and the turntable (231) is coupled to the elastic shaft (12) ) linked and moved together. In addition, a weight (2311), a limiting strip (2312) and a pawl (2313) are further disposed on the turntable (231). The limit strip (2312) is disposed coaxially with the pawl (2313) on the turntable (231), and the limit strip (2312) is secured by the spring (2314) to the pawl (2313). The pawl (2313) is held in an original position wherein the toothed ratchet (212) corresponds to the pawl (2313). The weight (2311) is also provided on the turntable (231).

When the door (not shown) is instantaneously applied with a force greater than a predetermined weight unit, the weight (2311) is subjected to centrifugal force against the pawl (2313), so that the pawl (2313) resists the spring. The elastic force of (2314) is pushed out toward the toothed ratchet (212) to hook against the toothed ratchet (212), so that the elastic rotating shaft (12) stops rotating, so that the connecting belt (13) pulls the connecting belt (13) The door (not shown) makes it impossible to open.

Further, the clutch locking unit (23) further includes an inductive limit protrusion (2315), and the inductive limit protrusion (2315) is an outer handle of the door (not shown) ( In the figure, there is no indication) mutual induction, and it is raised/lowered by the opening/closing of the outer handle (not shown).

Please refer to the first figure and the fifth figure. When the user does not pay attention to the rear car, or when the user applies the force through an inner handle (B1), the door (B) is quickly opened. The latching component (not shown in the figure) is because the door (B) is instantaneously opened and the applied force is greater than the preset weight unit, and the connecting strap (not shown) is locked, and the stretched state is no longer present. This reaches the door, so that the door (B) can only open a certain opening angle (B2) to avoid accidents.

Please match the third and fifth figures. In particular, when the outer handle (B3) is not pulled up, the inductive limit protrusion (2315) is lowered to allow the pawl (2313) to be freely hooked. Reached on the toothed ratchet (212). When the user opens the door (B) with an outer handle (B3) outside the vehicle, the opening of the outer handle (B3) will transmit an opening signal to the sensing limit protrusion (2315). The limit protrusion (2315) will assume a raised state, thereby pressing against the limit strip (2312), keeping the pawl (2313) in the original position, preventing the user from opening the door outside the vehicle (B) At the time, the trouble of opening the door due to the influence of the click element is greatly increased, and the convenience of the user is greatly increased.
