Technical Field

[0001] The utility model relates to the technical field of wheel speed collection, in particular to an external wheel speed collection device for a small passenger car. Background Art

[0002] As a common means of transportation, minibuses are mostly modified from special chassis or light truck chassis. They have developed rapidly in recent years, not only enriching the public transportation system, but also providing more choices for family and personal travel. In the vehicle production process, it is crucial to collect the wheel speed of the vehicle tires. The wheel speed signal, as an important parameter of the vehicle's driving state, directly affects the vehicle's driving safety, braking performance and fuel economy. Through real-time monitoring and analysis of the wheel speed signal, problems such as tire wear, insufficient air pressure or slippage can be discovered and solved in a timely manner;

[0003] At present, in terms of the acquisition of vehicle tire speed signals, most of the methods are to connect the odometer sensor to the car's central control to extract the original vehicle's wheel speed signal. Although this acquisition method can achieve the acquisition of wheel speed signals to a certain extent, there are still some problems:

[0004] Due to delays in signal transmission and processing, existing data collection methods may not be able to reflect changes in tire speed in real time, affecting the timely judgment of the vehicle's driving status.

[0005] In order to solve the above problems, this application proposes an external wheel speed collection device for a small passenger car. Utility Model Content

[0006] Based on the technical problems existing in the background technology, the utility model proposes an external wheel speed collection device for a small passenger car.

[0007] The utility model provides an external wheel speed collection device for a small passenger car, comprising an odometer sensor;

[0008] The rotor end of the odometer sensor is connected with an insert;

[0009] An end of the odometer sensor away from the fitting is provided with an orientation rod, so an angle block mounted on the wheel arch of the vehicle is provided above the odometer sensor, an axle cylinder is installed on the angle block, and the top end of the orientation rod slides through the angle block and the axle cylinder;

[0010] A fixing cylinder is installed on the outer periphery of the shaft cylinder, a pressure warning component is installed on the inner wall of the fixing cylinder, and an elastic pressing component is installed in the middle of the fixing cylinder to press against the directional rod and the pressure warning component respectively.

[0011] Preferably, the engaging part comprises a flower center shaft and a rubber ring, the flower center shaft is connected to the rotating end of the odometer sensor, and the end of the flower center shaft away from the odometer sensor is sleeved with a rubber ring.

[0012] Preferably, the pressure warning component includes a pressure sensor and an alarm, a through insertion channel is opened in the shaft cylinder, the top end of the directional rod slides through the insertion channel, a cavity connected to the insertion channel is opened in the fixed cylinder, the pressure sensor is installed on the inner wall of one end of the fixed cylinder away from the shaft cylinder, the alarm is installed on the outer side of one end of the fixed cylinder away from the shaft cylinder, and the alarm is electrically connected to the pressure sensor.

[0013] Preferably, the elastic pressure piece includes a fixed block, a pressure rod, a pressure block and a spring, the fixed block is installed in the middle of the cavity, a through hole is opened in the middle of the fixed block, the pressure rod slides transversely through the through hole and presses against the pressure sensor, the pressure block is installed at the end of the pressure rod away from the pressure sensor, the spring is sleeved on the pressure rod and located between the fixed block and the pressure block, and the two ends of the spring are respectively connected to the fixed block and the pressure block, a rolling groove is opened on the side of the pressure block close to the directional rod, and a ball is rollingly connected in the rolling groove to press against the directional rod.

[0014] Preferably, a bracket is installed at one end of the odometer sensor away from the flower center axis, a thread groove is opened in the bracket, and the bottom end of the directional rod is provided with an external thread, and the bottom end of the directional rod is threadedly connected in the thread groove.

[0015] The above technical solution of the utility model has the following beneficial technical effects:

[0016] By means of the odometer sensor, fittings and directional rod, the angle code block can be installed on the wheel arch of the vehicle, and then the directional rod on the odometer sensor can be passed through the angle code block and the shaft tube, and the fitting at the end of the odometer sensor can be fitted into the center hole of the wheel hub. When the vehicle is driving, the rotational force of the wheel hub can be transmitted to the rotor end of the odometer sensor through the fittings, driving the rotor end of the odometer sensor to rotate, thereby performing real-time wheel speed collection. In addition, the tire will avoid shock during driving, and during the process of avoiding shock, the directional rod can move freely up and down along the shaft tube to achieve smooth data collection. By installing the odometer sensor outside the wheel hub, this structure can realize real-time collection of wheel speed, timely determine the driving status, and improve the accuracy of wheel speed collection.

[0017] Through the setting of the fixing cylinder, since the elastic pressure piece is pressed against the pressure warning piece and the directional rod respectively, when the odometer sensor and the wheel hub fall off during driving of the vehicle, the directional rod will also fall off from the shaft cylinder, and then the elastic pressure piece will be separated from the pressure warning piece. After the force acting on the pressure warning piece is cancelled, an alarm will be issued. This structure can issue an alarm in time when the odometer sensor and the wheel hub are separated, which serves as a reminder and facilitates the staff to take measures.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] In this embodiment, the rotor end of the odometer sensor 1 is connected with a fitting 2. The fitting 2 includes a flower shaft 21 and a rubber ring 22. The flower shaft 21 is connected to the rotating end of the odometer sensor 1, and the end of the flower shaft 21 away from the odometer sensor 1 is sleeved with a rubber ring 22.

[0024] In this embodiment, an orientation rod 3 is installed on the end of the odometer sensor 1 away from the fitting 2, so an angle code block 4 installed with the vehicle wheel arch is provided above the odometer sensor 1, and an axle tube 5 is installed on the angle code block 4, and the top end of the orientation rod 3 slides through the angle code block 4 and the axle tube 5.

[0025] It should be noted that the angle code block 4 can be installed on the wheel arch of the vehicle, and then the directional rod 3 on the odometer sensor 1 can be passed through the angle code block 4 and the insertion channel opened in the shaft tube 5, and then the rubber ring 22 at the end of the odometer sensor 1 and the flower center shaft 21 are embedded in the center hole of the wheel hub. When the vehicle is running, the rotational force of the wheel hub can be transmitted to the rotor end of the odometer sensor 1 through the flower center shaft 21, driving the rotor end of the odometer sensor 1 to rotate, thereby performing real-time wheel speed collection, and the tire will avoid shock during driving. During the shock avoidance process, the directional rod 3 can move freely up and down along the insertion channel opened in the shaft tube 5, so as to realize smooth data collection. By installing the odometer sensor 1 outside the wheel hub, this structure can realize real-time collection of wheel speed, timely determine the driving status, and improve the accuracy of wheel speed collection.

[0026] In this embodiment, a fixed cylinder 6 is installed on the outer periphery of the shaft cylinder 5, and a pressure warning component 7 is installed on the inner wall of the fixed cylinder 6.

A through insertion channel is provided in the shaft cylinder 5, and the top end of the directional rod 3 slides through the insertion channel. A cavity connected to the insertion channel is provided in the fixed cylinder 6. The pressure sensor 71 is installed on the inner wall of one end of the fixed cylinder 6 away from the shaft cylinder 5, and the alarm 72 is installed on the outer side of one end of the fixed cylinder 6 away from the shaft cylinder 5, and the alarm 72 is electrically connected to the pressure sensor 71.

[0027] In this embodiment, an elastic pressure piece 8 is installed in the middle of the fixed cylinder 6, which is pressed against the directional rod 3 and the pressure warning member 7 respectively.
