Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an emergency brake collision sensing device for an electric vehicle. Background Art

[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Electric vehicles are usually referred to as vehicles that use batteries as energy sources and convert electrical energy into mechanical energy through controllers, motors and other components to control the current size to change the speed of the vehicle.

[0003] For example, an electric vehicle emergency braking body stabilization device disclosed in publication number CN216916115U is installed at the bottom between the two tires of the electric bicycle. It can stabilize the body of the electric bicycle by turning on the electric hydraulic rod when slipping, and forms a wheel support structure with the wheel of the electric bicycle, which can provide a more stable support effect and protect people's lives and property.

[0004] Although the above patent can ensure the stability of the vehicle body to a certain extent by setting its supporting structure, the tires of the electric vehicle will still be in motion due to the force of inertia after braking and cannot stop immediately. Therefore, there is a high possibility of collision, resulting in personal injury or damage to the electric vehicle. Therefore, an electric vehicle emergency brake collision sensing device is urgently needed to be developed. Utility Model Content

[0005] The utility model aims to provide an electric vehicle emergency brake collision sensing device, which has the advantage of automatic braking and solves the problems raised by the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an emergency brake collision sensing device for an electric vehicle, comprising: a tire, an inner cavity of the tire is provided with two outer plates, two brake rings are rotatably connected to the opposite sides of the two outer plates, and the opposite ends of the two brake rings are fixedly connected to connecting plates, and transmission blocks are provided on the opposite sides of the two connecting plates, and the inside of the transmission block is rotatably connected to a rotating rod, a motor is installed on the rear side of the rear outer plate, and the output shaft of the motor passes through the front side of the outer plate and is fixedly connected to the rotating rod, the inner cavity of the top brake ring is fixedly connected to a connecting frame 1, and the inner cavity of the bottom brake ring is fixedly connected to a connecting frame 2, and the inner cavities of the connecting frame 1 and the connecting frame 2 are fixedly connected to springs.

[0007] Furthermore, as a preferred embodiment of the present invention, opposite sides of the two outer panels are fixedly connected with fixing rods, and both ends of the fixing rods respectively penetrate to the outer sides of the outer panels and are rotatably connected with brackets.

[0008] Furthermore, as a preferred embodiment of the present invention, the other ends of the two brake rings are fixedly connected with positioning blocks, and the opposite sides of the two positioning blocks are embedded with positioning rods, and one end of the positioning rods is fixedly connected to the outer plate.

[0009] Furthermore, as a preferred embodiment of the present invention, a brake block is fixedly connected to the surface of the motor output shaft, and the brake block is located on the rear surface of the outer plate at the rear side.

[0010] Furthermore, as a preferred embodiment of the present invention, a support frame is installed on the surface of the motor, and one end of the support frame is fixedly connected to the outer plate at the rear side.

[0011] Beneficial effects. The technical solution of the present application has the following technical effects: the utility model has the advantage of automatic braking. In actual use, an automatic braking device is arranged in the inner cavity of the tire of the electric vehicle without affecting the normal function of the electric vehicle. When the rider brakes in an emergency, automatic braking can also be performed when the manual brake is performed. Therefore, under the operation of double braking, the inertia of the electric vehicle's movement can be greatly reduced, and the electric vehicle can be stopped immediately, thereby avoiding collision with objects in front, thereby protecting the safety of the rider and the integrity of the battery vehicle. Therefore, the technical solution has good market prospects and is worthy of promotion.

[0019] As attached Figure 1 To Attachment Figure 3 As shown: This embodiment provides an emergency brake collision sensing device for an electric vehicle, comprising: a tire 1, an inner cavity of the tire 1 is provided with two outer plates 2, two brake rings 3 are rotatably connected to the opposite sides of the two outer plates 2, and the opposite ends of the two brake rings 3 are fixedly connected to a connecting plate 4, and a transmission block 5 is provided on the opposite sides of the two connecting plates 4. The transmission block 5 is rotatably connected to a rotating rod 6 inside, a motor 7 is installed on the rear side of the rear outer plate 2, and a brake block 15 is fixedly connected to the surface of the output shaft of the motor 7. The brake block 15 is located on the rear surface of the rear outer plate 2, and the output shaft of the motor 7 passes through the front side of the outer plate 2 and is fixedly connected to the rotating rod 6, the inner cavity of the top brake ring 3 is fixedly connected to a connecting frame 1 8, the inner cavity of the bottom brake ring 3 is fixedly connected to a connecting frame 2 9, and the inner cavities of the connecting frame 1 8 and the connecting frame 2 9 are fixedly connected to a spring 10.

[0020] Specifically, the two opposite sides of the two outer plates 2 are fixedly connected with fixing rods 11 , and both ends of the fixing rods 11 respectively penetrate to the outer sides of the outer plates 2 and are rotatably connected with brackets 12 .

[0021] In this embodiment, the fixing rod 11 and the bracket 12 are used in coordination to connect the outer plate 2 and the tire 1 , thereby improving the stability of the outer plate 2 .

[0022] Specifically, the other ends of the two brake rings 3 are fixedly connected with positioning blocks 13 , and the opposite sides of the two positioning blocks 13 are embedded with positioning rods 14 , and one end of the positioning rods 14 is fixedly connected with the outer plate 2 .

[0023] In this embodiment, the positioning block 13 and the positioning rod 14 are used in combination to further strengthen the tightness of the connection between the outer plate 2 and the brake ring 3 while ensuring the trajectory of the two brake rings 3 when they move.

[0026] The working principle and use process of the utility model are as follows: through the collision sensor arranged at the front of the vehicle, when it senses that there is an object in front, the collision sensor turns on the motor 7 through the controller, and the output shaft of the motor 7 drives the transmission block 5 to rotate while driving the brake block 15 to rotate, so that the brake block 15 abuts against the tire 1, so that the transmission block 5 is in a vertical state, thereby pushing the two brake rings 3 to move in opposite directions, and through the coordinated use of the connecting frame 1 8 and the connecting frame 2 9, the spring 10 is pulled, so that the surfaces of the two brake rings 3 are in contact with or even abut against the wheel, and the motor 7 is turned off, so that the tire 1 stops. When the braking is completed, the motor 7 is turned on again, and the output shaft of the motor 7 moves in the opposite direction. Through the reverse direction coordination of the above-mentioned parts, the transmission block 5 is in a horizontal state, and under the action of the elastic force of the spring 10, the two brake rings 3 move relative to each other, so that the connecting plate 4 is in contact with the transmission block 5.
