Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted equipment, and more specifically, to an anti-drop driving recorder. Background Art

[0002] A driving recorder is a device installed on a vehicle to record images and sounds during the driving process of the vehicle. It can record video images and sounds of the entire driving process of the car, provide evidence for the determination of responsibility for traffic accidents, prevent malicious fraud, and record travel scenery, etc. The suction cup driving recorder is the most common one. It is powered by USB or cigarette lighter, and then adhered to the windshield with a suction cup. The advantage of this method is that it is easy to install, but the suction cup driving recorder in the prior art is often adsorbed by a single large suction cup. The front window glass of the car itself has a curvature, which causes a single suction cup to undergo a large arc deformation with the front window glass after adsorption. Long-term large arc deformation or when the vehicle collides can easily cause the suction cup to leak and fall off. Summary of the invention

[0003] In view of this, the present application provides an anti-drop driving recorder to solve the technical problem that the suction cup type driving recorder in the prior art is easy to fall.

[0004] The present application provides an anti-drop driving recorder, wherein the anti-drop driving recorder comprises: The driving recorder body and the connecting part include a supporting base and at least three suction cup adsorption mechanisms, the supporting base is connected to the driving recorder body, each of the suction cup adsorption mechanisms includes a retractable arc arm and a suction cup, the first end of the retractable arc arm in each of the suction cup adsorption mechanisms is connected to the supporting base, and the other end is connected to the corresponding suction cup.

[0005] Furthermore, the inner concave arc surface of each of the retractable arc-shaped arms faces the space surrounded by the at least three suction cup adsorption mechanisms.

[0006] Furthermore, the retractable arc-shaped arm includes an arc-shaped rod connected to the support seat and an arc-shaped sleeve slidably mounted on the arc-shaped rod, and the corresponding suction cup in each suction cup adsorption mechanism is connected to the end of the corresponding arc-shaped sleeve.

[0007] Furthermore, the connecting portion includes a locking mechanism for locking the arc-shaped sleeve to the corresponding arc-shaped rod.

[0008] Furthermore, the locking mechanism includes a threaded pressure rod passing through the arc sleeve and a knob connected to the end of the threaded pressure rod located outside the arc sleeve. When the knob is turned, the end of the threaded pressure rod extending into the arc sleeve can approach and abut against the arc rod in the arc sleeve or move away from the arc rod.

[0009] Furthermore, the connecting part includes a rotating pressure roller mechanism, which includes a rotating shaft and an elastic pressure arm structure rotatably connected to the support seat, one end of the elastic pressure arm structure is connected to the rotating shaft, and the other end of the elastic pressure arm structure is connected to the pressure roller, and the elastic pressure arm structure generates an elastic force on the pressure roller in a direction away from the support seat, so that when the suction cup is adsorbed on the vehicle glass, rotating the rotating shaft can enable the pressure roller to press over each suction cup.

[0010] Furthermore, the elastic pressure arm structure includes a first connecting arm and a second connecting arm, the first end of the first connecting arm is connected to the rotating shaft, the second end of the first connecting arm is hinged to the first end of the second connecting arm, and the second end of the second connecting arm is connected to the pressure roller.

[0011] Further, a torsion spring is provided at the hinge between the second end of the first connection and the first end of the second connecting arm, and the torsion spring generates an elastic force causing the second end of the second connecting arm to move in a direction away from the support base; or, a spring is connected between the first connecting arm and the second connecting arm, and the spring generates an elastic force causing the second end of the second connecting arm to move in a direction away from the support base.

[0012] Furthermore, the anti-drop driving recorder includes a motor drivingly connected to the rotating shaft, the motor is electrically connected to the timing start-stop switch circuit, and the motor is connected to the driving recorder body.

[0013] Further, the connecting part includes four suction cup adsorption mechanisms, and the four suction cup adsorption mechanisms are arranged in sequence at an angle of 90°. The four suction cup adsorption mechanisms include a first suction cup adsorption mechanism, a second suction cup adsorption mechanism, a first suction cup adsorption mechanism and a fourth suction cup adsorption mechanism. The retractable arc arm in the first suction cup adsorption mechanism and the retractable arc arm in the first suction cup adsorption mechanism are in the same plane, and the retractable arc arm in the second suction cup adsorption mechanism and the retractable arc arm in the fourth suction cup adsorption mechanism are in the same plane.

[0014] Compared with the prior art, since the anti-drop driving recorder provided by the present invention has three suction cup adsorption mechanisms, and the suction cup adsorption mechanisms include a retractable arc arm and a suction cup, the position of the corresponding suction cup can be adjusted by the retractable movement of the retractable arc arm, so that at least three suction cups are finally adsorbed on at least three different points on the inner side of the car's front windshield, and at least three suction cups form a more reliable and stable adsorption connection. In addition, compared with the case of a single suction cup, since more suction cups bring more adsorption connection points, the suction cup size can be designed to be smaller to form a plurality of dispersed suction cup connection positions, and the contact area between a single suction cup and the car's front windshield becomes smaller, and it is not easily affected by the deformation of the curvature of the front windshield, so it is not easy to cause the suction cup to deform and cause air leakage or fall off due to vehicle collision, causing the entire anti-drop driving recorder to fall.

[0015] In a further solution, the connecting part includes four suction cup adsorption mechanisms, and the four suction cup adsorption mechanisms are arranged in sequence at an angle of 90°.

The retractable arc arm in the first suction cup adsorption mechanism and the retractable arc arm in the first suction cup adsorption mechanism are in the same plane, and the retractable arc arm in the second suction cup adsorption mechanism and the retractable arc arm in the fourth suction cup adsorption mechanism are in the same plane. More suction cup adsorption mechanisms can provide more adsorption points, thereby improving the connection stability of the anti-drop driving recorder provided by the invention, especially the connection stability during a vehicle collision.

[0016] In a further solution, the connecting part includes a rotating pressure roller mechanism, which includes a rotating shaft rotatably connected to the support seat and an elastic pressure arm structure, one end of the elastic pressure arm structure is connected to the rotating shaft, and the other end of the elastic pressure arm structure is connected to the pressure roller. The elastic pressure arm structure generates an elastic force on the pressure roller in a direction away from the support seat, so that when the suction cup is adsorbed on the vehicle glass, the rotating shaft can make the pressure roller press over each suction cup. In this example, by rotating the rotating shaft, the pressure roller can press over each suction cup so that the suction cup can be pressed against the vehicle windshield. The rotating shaft can be operated regularly (manually or automatically) at intervals to regularly compensate for the degree of pressure of the suction cup against the vehicle glass, thereby ensuring that each suction cup is not easily fallen off the car windshield.

[0023] See also Figures 1 to 3 The present invention provides an anti-drop driving recorder, wherein the anti-drop driving recorder comprises: The driving recorder body 100 and the connecting part 200, the connecting part 200 includes a supporting base 201 and at least three suction cup adsorption mechanisms, the supporting base 201 is connected to the driving recorder body 100, each suction cup adsorption mechanism includes a retractable arc arm and a suction cup 202, and the first end of the retractable arc arm in each suction cup adsorption mechanism is connected to the supporting base 201, and the other end is connected to the corresponding suction cup 202.

[0024] Since the anti-drop driving recorder provided by the present invention has three suction cup adsorption mechanisms, and the suction cup adsorption mechanisms include a retractable arc arm and a suction cup 202, the position of the corresponding suction cup 202 can be adjusted by the retractable movement of the retractable arc arm, so that at least three suction cups 202 are finally adsorbed on at least three different points on the inner side of the car's front windshield, and at least three suction cups 202 form a more reliable and stable adsorption connection. In addition, compared with the case of a single suction cup 202, since more suction cups 202 bring more adsorption connection points, the size of the suction cup 202 can be designed to be smaller to form a plurality of dispersed suction cup connection positions, and the contact area between a single suction cup 202 and the car's front windshield becomes smaller, and it is not easily affected by the deformation of the curvature of the front windshield, so it is not easy to cause the suction cup 202 to deform and leak and fall off, thereby causing the entire anti-drop driving recorder to fall.

[0025] According to a specific embodiment of the present application, the connecting portion 200 includes four suction cup adsorption mechanisms, and the four suction cup adsorption mechanisms are arranged in sequence at an angle of 90°. The four suction cup adsorption mechanisms include a first suction cup adsorption mechanism, a second suction cup adsorption mechanism, a first suction cup adsorption mechanism and a fourth suction cup adsorption mechanism. The retractable arc arm in the first suction cup adsorption mechanism and the retractable arc arm in the first suction cup adsorption mechanism are in the same plane, and the retractable arc arm in the second suction cup adsorption mechanism and the retractable arc arm in the fourth suction cup adsorption mechanism are in the same plane. Of course, three suction cup adsorption mechanisms or five suction cup adsorption mechanisms or more suction cup adsorption mechanisms can also be designed. More suction cup adsorption mechanisms can provide more adsorption points, thereby improving the connection stability of the anti-drop driving recorder provided by the invention, especially the connection stability during a vehicle collision.

[0026] According to a preferred embodiment of the present application, the concave arc surface of each retractable arc-shaped arm faces the space surrounded by at least three suction cup adsorption mechanisms.

[0027] Specifically, the driving recorder body 100 includes a first housing 101 and a second housing 102 connected to the first housing 101 at an angle (preferably an obtuse angle), a camera 103 is installed on the first housing 101, a support base 201 is connected to the first surface of the second housing 102, the second surface of the second housing 102 forms an obtuse angle with the first housing 101, and the concave arc surface of each retractable arc arm faces the center of the support column and is perpendicular to the central axis of the second housing 102.

[0028] According to a specific embodiment of the present application, the retractable arc arm includes an arc rod 203 connected to a support seat 201 and an arc sleeve 204 slidably mounted on the arc rod 203. The corresponding suction cup 202 in each suction cup adsorption mechanism is connected to the end of the corresponding arc sleeve 204. The end of the arc sleeve 204 can be connected to the suction cup rod 205 through a universal ball joint. The suction cup 202 is connected to the suction cup rod 205. The connecting part 200 includes a locking mechanism for locking the arc sleeve 204 to the corresponding arc rod 203.

[0029] According to one embodiment of the present application, the locking mechanism includes a threaded pressure rod 206 passing through the arc sleeve 204 and a knob 207 connected to the end of the threaded pressure rod 206 located outside the arc sleeve 204. The arc sleeve 204 has a threaded through hole for the threaded pressure rod 206 to be threadedly connected and pass through. When the knob 207 is turned, the end of the threaded pressure rod 206 extending into the arc sleeve 204 can approach and abut against the arc rod 203 in the arc sleeve 204 or move away from the arc rod 203.

[0030] According to another embodiment of the present application, the locking mechanism may also be a latching tooth that cooperates between the arc sleeve 204 and the arc rod 203. When the arc sleeve 204 is not subjected to external force, the arc sleeve 204 and the arc rod 203 are positioned (fixed) by direct latching tooth cooperation. When the arc sleeve 204 is subjected to external force, the latching teeth that cooperate between the arc sleeve 204 and the arc rod 203 can slide against each other.

The elastic pressure arm structure generates an elastic force on the pressure roller 209 in a direction away from the support seat 201, so that when the suction cup 202 is adsorbed on the vehicle glass, the rotating shaft 208 can make the pressure roller 209 press over each suction cup 202. In this example, by rotating the rotating shaft 208, the pressure roller 209 can press over each suction cup 202 so that the suction cup 202 can be pressed against the vehicle windshield. The rotating shaft 208 can be operated regularly (manually or electrically controlled automatically) at intervals to regularly compensate for the degree of pressure of the suction cup 202 against the vehicle glass, thereby ensuring that each suction cup 202 is not easily fallen off the car windshield.

[0032] According to a preferred embodiment of the present application, the anti-drop driving recorder includes a motor 210 that is transmission-connected to the rotating shaft 208. The motor 210 is electrically connected to the timing start-stop switch circuit and can be set through a program so that the motor 210 is regularly turned on for a period of time, regularly drives the rotating shaft 208 to rotate, and drives the pressure roller 209 to rotate multiple times to press each suction cup 202, so that the degree of pressure of the suction cup 202 on the vehicle glass is regularly compensated, so that the suction cup 202 can always maintain a high adsorption force (adsorption degree) on the car windshield. The motor 210 is connected to the second housing 102 and protrudes from the second housing 102.

[0033] According to a specific embodiment of the present application, the elastic pressure arm structure includes a first connecting arm 211 and a second connecting arm 212, the first end of the first connecting arm 211 is connected to the rotating shaft 208, the second end of the first connection is hinged to the first end of the second connecting arm 212, and the second end of the second connecting arm 212 is connected to the pressure roller 209.

[0035] According to another embodiment of the present application, a spring may be connected between the first connecting arm 211 and the second connecting arm 212 , and the spring may also generate an elastic force that causes the second end of the second connecting arm 212 to move in a direction away from the support seat 201 .

[0036] It should be noted that the above embodiments only express the preferred implementation of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the present application. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, such as combining different features in various embodiments, etc., which should all fall within the scope of protection of the present application.
