Description

Technical Field

[0001] The present application relates to the field of vehicles, and in particular to a hidden safety door handle for vehicles. Background Art

[0002] The design of the door handle is an important embodiment of the vehicle's detail processing, for three reasons: first, the door handle is generally the most protruding point of the vehicle's side styling surface, and is visually very obvious. The form of the door handle will directly affect the vehicle's side exterior styling; second, as a control component for the opening of the door, the door handle must meet a series of structural requirements such as door opening / closing / sealing, and must also meet the ergonomic requirements when the door is opened; third, if the door handle is properly designed, such as a hidden door handle, it can effectively reduce wind resistance and thus reduce fuel consumption.

[0003] Most of the existing hidden door handles are of the pop-up type. When the car door needs to be opened, the car owner uses a remote control to unlock the door handle so that the door handle pops out, and then the car owner pulls the door handle outwards to open the car door.

[0004] The above-mentioned existing technical solutions have the following defects: when a traffic accident occurs, the power failure of the car will cause the hidden door handle to fail to pop out normally, making it difficult for rescuers to rescue the people in the car. Secondly, in a freezing rain environment, there is still a handhold to quickly open the door after the shell is frozen. Utility Model Content

[0005] In order to solve the problem that the hidden door handle cannot be opened after an accident or power outage, the present application provides a hidden safety door handle for a vehicle.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A hidden safety door handle for a vehicle comprises a door handle and a baffle. The door handle is arranged on the surface of the vehicle door and is flush with the surface of the vehicle door. The door handle is connected to the door lock structure of the vehicle door. A force groove is provided on the inner side of the vehicle door where the door handle is arranged to facilitate an operator to pull out the door handle. The baffle is arranged near the door handle. When the baffle is in a closed state, the baffle is flush with the door handle. A rotating shaft is fixedly connected to the side of the baffle facing away from the door handle. The rotating shaft is rotationally connected to the vehicle door. The rotating shaft is connected to an opening and closing control structure for controlling the baffle and rotating.

[0008] By adopting the above solution, when the car is parked, the baffle is in an open state, so that the operator can put his hand into the force groove at the opening of the baffle and hold the handle, and then the operator pulls the handle outward to open the door. After the car starts, the opening and closing control structure drives the baffle to rotate around the rotating shaft, so that the baffle is closed, and the door handle is hidden. When an accident occurs, the opening and closing control structure is closed, thereby releasing the control of the opening and closing control structure on the baffle, so that the baffle can be opened, so that the operator can put his hand into the force groove, and thus can open the door.

[0009] Optionally, the opening and closing control structure includes an inclined plate, a first magnetic plate and an electromagnet, a control cavity is opened below the force groove, the side of the control cavity close to the outer side of the vehicle plate is an outer door panel, and the side of the control cavity close to the inner side of the vehicle plate is an inner door panel, the inclined plate is fixedly connected to the circumferential surface of the rotating shaft, the inclined plate is inclined relative to the baffle plate toward the inner door panel, the first magnetic plate is connected to the side of the inclined plate away from the baffle plate, the electromagnet is arranged on one side of the inner door panel, the electromagnet is connected to a power supply, and a speed sensor is connected between the electromagnet box and the power supply.

[0010] By adopting the above technical solution, when the car starts and reaches a certain speed, the speed sensor senses the vehicle speed, the electromagnet is energized, and the electromagnet attracts the first magnetic plate, thereby driving the inclined plate to move toward the inner door panel, thereby driving the baffle to be converted to a closed state. When the car is in a stopped state or the power is cut off, the electromagnet is de-energized, thereby releasing the electromagnet's attraction to the first magnetic plate, allowing the baffle to open, and allowing the operator to open the door.

[0011] Optionally, the first magnetic plate is hinged to the inclined plate.

[0012] By adopting the above technical solution, the angle between the first magnetic attraction plate and the inclined plate is changed, so that the first magnetic attraction plate can be in closer contact with the electromagnet, and the inclined plate can rotate at a larger angle, thereby enabling the baffle to rotate at a larger angle.

[0013] Optionally, a torsion spring is sleeved on the outer side of the rotating shaft, and two sides of the torsion spring are respectively connected to the outer door panel and the inclined plate. When the torsion spring is in a normal state, the baffle is in an open state.

[0014] By adopting the above technical solution, when the baffle is in a closed state, the torsion spring is in a compressed state. When the vehicle stops or the power is cut off, the electromagnet releases the control of the first magnetic attraction plate, and the torsion spring rebounds to convert the baffle to an open state, so that the baffle can remain in an open state when the vehicle stops or the power is cut off.

[0015] Optionally, the groove surface of the force-receiving groove is a smooth arc surface.

[0016] By adopting the above technical solution, the surface of the force groove is smooth, so that the operator is not easily scratched when putting his hand into the force groove. At the same time, the arc-shaped groove bottom is more in line with the curved shape of the hand, making it more comfortable for the operator to open the door.

[0017] Optionally, a clamping cavity is provided in the vehicle plate, and a clamping opening is provided in the upper part of the clamping cavity and is connected to the force groove, one side of the electromagnet is located in the control cavity, and the other side of the electromagnet is located in the clamping cavity, and a clamping structure is provided in the clamping cavity, the clamping structure includes a rotating disk, a clamping rod and a second magnetic plate, the rotating disk is rotatably connected in the clamping cavity, the clamping rod is fixedly connected to the circumferential surface of the rotating disk, the clamping rod is triangular at one end away from the rotating disk, the clamping rod is arranged at the clamping opening, a clamping rod is fixedly connected at the clamping opening opposite to the baffle, the clamping rod is triangular at one end away from the baffle, the clamping rod is connected to a spring, and one end of the spring away from the clamping rod is fixedly connected to the inner wall of the clamping cavity, when the spring is at its original length, the clamping rod clamps the clamping rod, and the second magnetic plate is arranged at the rotating disk close to the electromagnet.

[0018] By adopting the above technical solution, when the baffle is in the open state, the locking rod is clamped by the clamping rod, thereby ensuring that the baffle remains in the open state. When the vehicle starts, the electromagnet is started, and the electromagnet attracts the first magnetic plate and the second magnetic plate, so that the second magnetic plate drives the rotating disk to rotate, thereby driving the clamping rod away from the locking rod. At the same time, the first magnetic plate drives the inclined plate and the baffle to move, so that the baffle is closed.

[0019] Optionally, the rotating disk is fixedly connected to a connecting rod, and one end of the connecting rod facing away from the rotating disk is hinged to the second magnetic attraction plate.

[0020] By adopting the above technical solution, the second magnetic attraction plate can drive the rotating disk to rotate at a larger angle, and at the same time, the second magnetic attraction plate can be more stably adsorbed on the surface of the electromagnet.

[0021] In summary, this application has the following technical effects:

[0022] By setting a baffle and an opening and closing control structure, the operator can open the door when the vehicle is powered off;

[0023] The baffle is in an open state when the car is parked by setting a torsion spring;

[0024] The force-carrying groove is arranged so that the groove surface is an arc surface, so that the operator can open the door more comfortably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. Example 1

[0030] Reference Figure 1 A hidden safety door handle for a vehicle comprises a door handle 2 and a baffle 3. A smooth arc-shaped traction groove 11 is provided on the surface of the vehicle door 1. The door handle 2 is arranged in the traction groove 11. The door handle 2 is connected to the door lock of the vehicle door 1. There is a gap between the door handle 2 and the bottom of the traction groove 11 that is large enough for a person to reach in. The baffle 3 is arranged below the door handle 2. When the baffle 3 is in a closed state, the surface of the baffle 3 is flush with the surface of the vehicle door 1. The baffle 3 is hinged to the vehicle door 1 at the side away from the door handle 2. An opening and closing control structure for controlling the opening and closing of the baffle 3 is connected to the side of the baffle 3 away from the door handle 2. In the stopped state, the baffle 3 is in the open state, and the operator can put his hand into the force groove 11 through the opening of the baffle 3 and hold the door handle 2, thereby pulling out the door handle 2 to open the vehicle door 1. When the vehicle starts, the opening and closing control structure drives the baffle 3 to close, making the surface of the vehicle door 1 smooth, thereby reducing the wind resistance of the vehicle. When the car has an accident or the power is cut off, the opening and closing control structure releases the control of the vehicle door 1, so that the baffle 3 can be opened, so that the operator can put his hand into the force groove 11 to pull out the door handle 2, thereby opening the vehicle door 1.

[0031] Reference Figure 1 and Figure 2An operating chamber connected to the force groove 11 is provided below the force groove 11. The side of the operating chamber close to the outside of the door 1 is the outer door panel 13, and the side of the operating chamber close to the inside of the door 1 is the inner door panel 14. The opening and closing control structure is arranged in the operating chamber. The opening and closing control structure includes a slant plate 5, a first magnetic plate 6 and an electromagnet 7. A rotating shaft 4 is fixedly connected to the side of the baffle 3 away from the door 1. The axis of the rotating shaft 4 is parallel to the plate surface of the door 1. Both ends of the rotating shaft 4 are rotatably connected to the door 1. One side of the slant plate 5 is fixedly connected to the rotating shaft 4. The slant plate 5 is inclined toward the inner door panel 14. The first magnetic plate 6 is hinged on the side of the slant plate 5 away from the baffle 3. The electromagnet 7 is fixedly arranged on the surface of the inner door panel 14. The electromagnet 7 is connected to a power supply. A speed sensor is arranged between the electromagnet 7 and the power supply. When the vehicle is stationary, the electromagnet 7 is disconnected from the power supply and has no magnetism. When the vehicle starts and reaches a certain speed, the speed sensor senses that the vehicle is started, so that the electromagnet 7 is connected to the power supply, and the electromagnet 7 is magnetized. The electromagnet 7 attracts the first magnetic plate 6, so that the first magnetic plate 6 is adsorbed on the surface of the electromagnet 7, thereby driving the inclined plate 5 to rotate toward the inner door plate 14, thereby driving the baffle 3 to close. When the vehicle has an accident or power failure, the electromagnet 7 is disconnected from the power supply, and the electromagnet 7 loses magnetism, thereby releasing the control of the first magnetic plate 6, so that the baffle 3 can be opened, so that the operator can put his hand into the force groove 11, thereby opening the door 1. The magnetism of the electromagnet 7 is weak, and the operator can forcefully open the baffle 3 when the electromagnet 7 is energized.

[0032] Reference Figure 2 A torsion spring 8 is sleeved on the rotating shaft 4, and the two ends of the torsion spring 8 are respectively connected to the outer door panel 13 and the inclined plate 5. When the torsion spring 8 is in the original length state, the baffle 3 is in the open state. When the car starts, the electromagnet 7 is energized to absorb the first magnetic plate 6, thereby driving the inclined plate 5 to move toward the inner door panel 14, thereby driving the torsion spring 8 to generate elastic force. When the car stops or the power is cut off, the torsion spring 8 rebounds and drives the inclined plate 5 to move toward the outer door panel 13, thereby opening the baffle 3.

[0033] The specific implementation principle of the present application is as follows: when the car is stationary, the baffle 3 is in an open state, and the operator can extend his hand into the force groove 11 at the opening of the baffle 3, and then pull the door handle 2 outward to open the car door 1. When the car starts, the speed sensor senses the start of the car, connects the power supply to the electromagnet 7, so that the electromagnet 7 is magnetized, and the electromagnet 7 attracts the first magnetic plate 6, thereby driving the inclined plate 5 to move toward the inner door panel 14, thereby driving the baffle 3 to close and reduce the wind resistance of the car. When the car has an accident or the power is cut off, the electromagnet 7 loses magnetism, thereby releasing the adsorption of the first magnetic plate 6, and the torsion spring 8 rebounds to open the baffle 3, so that the operator can open the car door 1. Compared with the existing hidden door handle 2, the door handle 2 can be opened normally when the vehicle has an accident, thereby improving the safety of the car. Example 2

[0034] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a clamping cavity 15 is opened in the vehicle plate, and a clamping port 151 connected to the force groove 11 is opened in the clamping cavity 15. One side of the electromagnet 7 is located in the control cavity 12, and the other side of the electromagnet 7 is located in the clamping cavity 15. A clamping structure 9 is arranged in the clamping cavity 15, and the clamping structure 9 includes a rotating disk 91, a clamping rod 92 and a second magnetic plate 93. A rotating shaft 911 is arranged in the middle of the rotating disk 91, and the rotating shaft 911 is rotatably connected to the inner wall of the clamping cavity 15. The clamping rod 92 is fixedly arranged on the circumferential surface of the rotating disk 91, and the clamping rod 92 is arranged near the clamping port 151. The end of the clamping rod 92 away from the rotating disk 91 is triangular, and a clamping rod 922 is fixedly arranged at the baffle 3 opposite to the clamping port 151, and the end of the clamping rod 922 away from the baffle 3 is triangular. The clamping rod 92 is connected to a spring 921, and one end of the spring 921 is away from the clamping rod 92 and fixedly connected to the inner wall of the clamping cavity 15. When the spring 921 is at its original length, the clamping rod 92 clamps the clamping rod 922. A connecting rod 931 is fixedly connected to the rotating disk 91 near the electromagnet 7, and one end of the connecting rod 931 is away from the rotating disk 91 and is hinged to the second magnetic plate 93. When the car is in a stationary state, the clamping rod 92 clamps the clamping rod 922 at the clamping port 151, so that the baffle 3 can maintain an open state. When the car starts, the electromagnet 7 generates a magnetic force, thereby adsorbing the first magnetic plate 6 and the second magnetic plate 93, thereby driving the rotating disk 91 to rotate, thereby driving the clamping rod 92 to move in a direction away from the clamping rod 922, so that the clamping rod 922 is released, so that the baffle 3 is closed, reducing the wind resistance of the car.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
