Description

Technical Field

[0001] The utility model relates to the technical field of sensor equipment, in particular to a new sensor structure. Background Art

[0002] ABS sensor, or anti-lock braking system sensor, is an integral part of modern automotive safety technology. Its core function is to monitor the rotation speed of the wheels in real time and transmit this data to the ABS control unit. By precisely controlling the brake pressure, ABS sensors help vehicles maintain wheel-road friction during emergency braking, thereby preventing wheel locking and improving vehicle handling and braking effectiveness.

[0003] However, existing ABS sensor installation methods have some limitations. Usually, ABS sensors are fixed to the wheels or hubs by bolts, which is particularly inconvenient on vehicles with limited space. During the installation process, technicians need to operate in a narrow space, which not only increases the difficulty of installation, but also may affect the stability and reliability of the sensor due to improper installation.

[0004] In addition, although some ABS sensors are installed by plug-in in an attempt to simplify the installation process and improve convenience, this design still faces challenges in actual use. Vehicles will inevitably encounter bumpy road conditions during daily driving. Under the influence of long-term vibration, the ABS sensor circuit may become loose or even fall off, resulting in poor contact. This poor contact will directly affect the transmission of signals, making it impossible for the ABS system to accurately receive wheel speed information, thereby affecting the braking performance of the entire system.

[0005] In addition, the sensing part of the ABS sensor is easily covered by dirt, mud and other pollutants under bad road conditions. These pollutants will interfere with the sensor's sensing of the vehicle speed signal, reduce the accuracy of the signal, and even cause the system to misjudge and fail to work properly. In extreme cases, this may cause the ABS system to fail, increasing driving safety risks.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original sensor structure. Utility Model Content

[0009] Preferably, both side end faces in the installation groove and the areas on both sides corresponding to the sensor are configured as toothed surfaces to increase friction and reduce shedding, and a port is provided on the installation groove to facilitate the sensor to monitor the rotation state of the shaft.

[0010] Preferably, the anti-loosening and decontamination structure includes a fastening part and a decontamination part, the fastening part includes a connecting shaft, a bevel gear set, an empty slot, a first support shaft, a connecting auxiliary part, a second support shaft, a locking slot, a locking block, a movable plug rod, a mounting block, and a rough wheel, the rotating wheel is connected to the connecting shaft, and the end of the connecting shaft is connected to the bevel gear set, the bevel gear set is located in the empty slot, and the empty slot is opened in the mounting plate, a first support shaft is connected between the bevel gear set and the empty slot, a connecting auxiliary part is connected to the first support shaft, and the connecting auxiliary part is connected to the second support shaft, the second support shaft is rotatably connected to one side of the empty slot, and a locking slot is opened in the second support shaft, and a locking block is connected in the locking slot, the locking block is connected to one end of the movable plug rod, and the other end of the movable plug rod is located in the mounting block, and the mounting block is connected to the other side of the empty slot, the outer wall of the movable plug rod is slidably connected to the rough wheel, and the rough wheel fits the outer wall of the sensor.

[0011] Preferably, the upper portion of the locking groove is arranged in the shape of an annular groove, and a plurality of locking vertical grooves are arranged at equal angles below the annular groove, and the locking groove is shaped like a comb that is bent in an annular shape.

[0012] Preferably, the dirt removal part includes a fan blade disk, a box body, an input pipe, and an output pipe. The upper end of the first support shaft is connected to the fan blade disk, and the fan blade disk is located in the box body, and the box body is installed on the outer wall of the mounting disk. The two sides of the box body are respectively connected to the input pipe and the output pipe, and the end of the output pipe is fixed to the end surface of the mounting disk close to the sensor area.

[0013] Preferably, the connecting auxiliary part is configured as a chain assembly and a full gear assembly for transmitting the first support shaft and the second support shaft, and the cross-sections of the second support shaft and the mounting block are both "concave" structures.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the new sensor structure facilitates the plug-in installation of the sensor through the setting of the installation groove, and through the setting of the opening, the rotating wheel, and the anti-loosening and decontamination structure, when the shaft rotates, the friction force drives the rotating wheel to rotate accordingly, and then connects the shaft, the bevel gear set and the first support shaft through the transmission mechanism. This transmission effect enables the first support shaft to drive the fan blade disc to rotate effectively, thereby optimizing air flow.

[0017] In order to further improve the performance of the sensor, we introduce outside air through the input tube, and then use the output tube to accurately apply the air to the sensing area of ​​the sensor. This process not only promotes air circulation, but also effectively avoids the adhesion and obstruction of dirt, ensuring the continuous and accurate sensing of the sensor.

[0018] In addition, we have set up a trigger structure to deal with the possibility of the sensor being shaken loose. Once the sensor becomes loose, the trigger structure will respond immediately, activating the movable plug rod, which in turn drives the locking block to engage with the locking slot. At this time, the rotation of the rough surface wheel pushes the sensor into the installation slot and tightens it, thereby restoring its original stability and accuracy.

[0035] Working principle: According to Figure 1 As shown, firstly, the mounting plate 1 is mounted on the mounting area of ​​the vehicle, and the sensor 7 is inserted into the mounting groove 2 to complete the quick installation. The friction in the mounting groove 2 is increased to reduce the tooth surface that falls off, and the friction between the mounting groove 2 and the sensor 7 is increased to reduce the occurrence of falling off. After driving for a long time on a bumpy road, when the sensor 7 is loose in the mounting groove 2, the sensor 7 is separated from the compression of the reset plug 603, and the reset spring 602 drives the reset plug 603 to return to the mounting groove 2 in the groove 601.

Therefore, when the second support shaft 506 rotates, the positioning groove 507 and the positioning block 508 drive the movable plug rod 509 and the rough surface wheel 511 to rotate. The rotation of the rough surface wheel 511 pushes the sensor 7 into the mounting groove 2 for fastening.

[0036] The rotation of the first support shaft 504 drives the fan disc 512 to rotate, and the outside air is introduced into the box body 513 through the input pipe 514, and then acts on the sensing area of ​​the sensor 7 through the output pipe 515, so as to prevent the area from being affected by the adhesion of dirt. This is the working principle of the new sensor structure.
