Description

Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a gas brake glass micro-fusion sensor. Background Technology

[0002] A vehicle brake sensor is an electronic sensing device installed in a car's braking system. Its core function is to monitor the driver's braking intention, the force and speed of the braking action, and the state of the wheels during braking in real time. It converts this physical information into electrical signals and transmits them to other control systems of the vehicle, thereby achieving safer and smarter vehicle control.

[0003] Because the brake sensor needs to be connected to a cable, and the brake sensor is connected to the surface of the brake master cylinder, it needs to be tightened with a torque wrench. Currently, the brake sensor is usually tightened with a torque wrench before the cable is connected. However, because the space for the brake sensor in the vehicle is small, the cable connection is quite troublesome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a gas brake glass micro-fusion sensor.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a micro-fusible sensor for air brake glass, comprising: a sensor and an interface disposed on the surface of the sensor for connecting a cable; It also includes an inner cylinder set on the surface of the sensor to hold the sensor in place, a top plate on the surface of the inner cylinder for connecting a wrench, an outer cylinder on the outside of the inner cylinder to prevent deformation of the inner cylinder, and an outer groove on the surface of the outer cylinder for accommodating the cable.

[0006] Preferably, the surface of the inner cylinder is provided with an inner connecting groove for cable entry and exit.

[0007] Preferably, the surface of the outer cylinder is provided with an external connecting groove for cable entry and exit.

[0008] Preferably, the surface of the top plate is provided with protrusions, and the surface of the outer cylinder is provided with an inner groove for accommodating the protrusions.

[0009] Preferably, the outer side of the inner cylinder is provided with a longitudinal plate, which is used to lock the horizontal position of the outer cylinder.

[0010] Preferably, the surface of the top plate is provided with an outer plate, which is used to limit the vertical position of the outer cylinder.

[0011] Preferably, the top plate has a deep groove inside that cooperates with a wrench.

[0012] Compared with the prior art, the beneficial effects of this utility model include: by fitting the outer cylinder and the inner cylinder together on the sensor surface, it is convenient to tighten the sensor with a torque wrench. The cable on the interface surface can be pulled out from the inner groove and the outer groove. At the same time, the outer groove and the inner groove are set to allow the cable to enter and exit. After the sensor is installed, the outer cylinder and the inner cylinder can be separated from each other, so that the sensor is connected to the cable first and then fixed. This connection method avoids the trouble caused by fixing the sensor first and then connecting the cable. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Example 1 According to one embodiment of the present invention, in conjunction with Figures 1-5 As shown, This invention provides a micro-fuse sensor for air brake glass, the core of which lies in the use of the inner and outer cylinders to achieve stable sensor installation, standardized cable laying, and convenient installation operation.

[0023] Referring to the attached diagram, the air brake glass micro-fusion sensor mainly includes a sensor 4, an inner cylinder 7, and an outer cylinder 3.

[0024] Sensor 4 is manufactured using glass micro-fusion technology and is used to detect pressure signals; an interface 6 is provided on the surface of sensor 4, which is used to connect a cable for transmitting signals.

[0025] The inner cylinder 7 is fixedly sleeved on the surface of the sensor 4, and its main function is to hold and fix the sensor 4 during installation. The top of the inner cylinder 7 is provided with a top plate 1, which is preferably polygonal, and its side can be gripped by a wrench to apply torque to screw the entire sensor assembly into the installation position. In order to cooperate more stably with the wrench and prevent slippage, a deep groove matching the wrench specification can be opened in the inside of the top plate 1 to increase the contact area and facilitate the transmission of large torque.

[0026] The outer cylinder 3 is fitted on the outside of the inner cylinder 7. The core function of the outer cylinder 3 is to act as a protective outer sleeve to prevent excessive torque from directly acting on the inner cylinder 7 when the top plate 1 is tightened with a wrench, which could cause plastic deformation or damage to the inner cylinder 7, thereby ensuring the installation accuracy and long-term stability of the sensor 4.

[0027] To facilitate cable laying, one or more external slots 5 are provided on the surface of the outer cylinder 3. After the cable is led out from the interface 6 of the sensor 4, it can be accommodated in the external slots 5, making the cable route neat and avoiding clutter, while being protected by the outer cylinder 3. Furthermore, an internal connecting slot 12 is provided at a corresponding position on the surface of the inner cylinder 7, and an external connecting slot 8 is provided on the surface of the outer cylinder 3. The internal connecting slot 12 and the external connecting slot 8 together form a channel for the cable to pass from the sensor interface 6 to the external environment, ensuring that the cable can pass smoothly between the inner cylinder 7 and the outer cylinder 3.

[0028] To ensure the relative positional relationship between the inner and outer cylinders, this invention features an ingenious positioning and limiting structure. Horizontal position locking: At least one radially protruding longitudinal plate 11 is provided on the outer side wall of the inner cylinder 7; when the outer cylinder 3 is fitted onto the inner cylinder 7, the longitudinal plate 11 cooperates with the outer cylinder 3 to effectively restrict the outer cylinder 3 from rotating horizontally around the inner cylinder 7, ensuring that the outer slot 5 and the inner connecting slot 12 are always aligned.

[0029] Vertical position restriction: An outer plate 2 is provided extending downward on the lower surface of the top plate 1; the outer plate 2 surrounds the upper periphery of the inner cylinder 7, and its inner wall is engaged with the top outer wall or end face of the outer cylinder 3; when the outer cylinder 3 is installed in place, the outer plate 2 can be fastened to the top of the outer cylinder 3, thereby restricting the axial movement of the outer cylinder 3 relative to the inner cylinder 7 upward or downward, and preventing it from falling off or loosening.

[0030] Circumferential positioning: A protrusion 10 is provided on the lower surface of the top plate 1. Correspondingly, an inner groove 9 is provided on the top surface or inner top of the outer cylinder 3. During assembly, the protrusion 10 deforms and embeds into the inner groove 9, which not only provides additional circumferential positioning to prevent relative rotation between the two, but also enhances the integrity of the entire assembly.

[0031] Installation process in brief: First, connect the cable to the interface 6 of the sensor 4; then, place the inner cylinder 7 onto the sensor 4; next, pass the cable through the inner connecting groove 12 on the inner cylinder 7, and place the outer cylinder 3 over the inner cylinder 7, ensuring that the cable also passes through the outer connecting groove 8 on the outer cylinder 3; during this process, make the longitudinal plate 11 on the inner cylinder 7 fit into the corresponding structure inside the outer cylinder 3, and the protrusion 10 on the top plate 1 also embed into the inner groove 9 of the outer cylinder 3; finally, the outer plate 2 below the top plate 1 fastens to the top of the outer cylinder 3; after assembly, neatly place the cable in the outer slot 5 of the outer cylinder 3; finally, use a wrench to secure it to the top. The deep groove inside plate 1 is used to screw the entire assembly and install sensor 4 into the designated position of the air brake system. After installation, pull the outer cylinder 3 down, and the outer cylinder 3 moves relative to the inner cylinder 7. The cable is located in the outer slot 5 on the surface of the outer cylinder 3 and the inner connecting slot 12 on the surface of the inner cylinder 7. When the outer cylinder 3 moves, the cable detaches from the upper end of the outer slot 5. Remove the outer cylinder 3, and the cable is now located in the inner connecting slot 12 on the surface of the inner cylinder 7. The inner cylinder 7 can then be removed. This effectively completes the connection method of first connecting sensor 4 to the cable and then fixing sensor 4, avoiding the trouble caused by fixing sensor 4 first and then connecting the cable.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
