Description
Technical Field
[0001] This utility model relates to the field of sensor installation technology, specifically to a shock-resistant and anti-loosening sensor mounting base. Background Technology
[0002] With the continuous development of modern vehicle technology, vehicle sensors are being used more and more widely in in-vehicle systems, especially in intelligent and automated control systems, where the installation and stability of sensors are crucial to the reliability of the system. Sensors are typically used to detect various parameters of the vehicle body, such as temperature, pressure, and acceleration, and their accuracy directly affects the vehicle's performance and safety.
[0003] Existing sensor mounting brackets typically employ traditional fastening structures to secure the sensor body. These brackets are connected to the vehicle body via bolts or other fasteners. However, in practical applications, this structure is susceptible to factors such as vehicle vibration and external impacts, leading to loosening or insecure fixation of the sensor body, thus affecting its normal operation. Furthermore, since vehicles generate significant vibrations and impacts during operation, traditional mounting structures fail to effectively mitigate these vibrations, negatively impacting the long-term stability and accuracy of the sensor.
[0004] To address these issues, this invention provides a shock-resistant and anti-loosening sensor mounting base. Utility Model Content

The limiting mechanisms and the toothed grooves form a ratchet mechanism.
[0009] Preferably, the extrusion mechanism includes a movable ring, and a plurality of telescopic columns are symmetrically fixed on the top wall of the movable ring;
[0010] The top of the telescopic column is fixedly connected to the top wall of the mounting groove, and a No. 1 spring is sleeved on the outside of the telescopic column.
[0011] The first spring is fixed between the top wall of the movable ring and the top wall of the mounting groove.
[0012] Preferably, a rubber damping pad is glued to the contact position between the bottom wall of the movable ring and the sensor body.
[0013] Preferably, the telescopic column includes a sleeve, the sleeve is fixed to the top wall of the movable ring, the sleeve is filled with hydraulic oil, and a piston is slidably installed inside the sleeve;
[0014] The piston body is symmetrically provided with several throttling holes, and a movable column is fixed in the center of the top wall of the piston.

[0019] Beneficial effects
[0020] This utility model provides a shock-resistant and anti-loosening sensor mounting base. Compared with the prior art, it has the following advantages:
[0021] (1) The anti-vibration and anti-loosening sensor mounting base, through the cooperation design of fasteners and tooth grooves, can prevent reverse rotation after tightening, thereby achieving the anti-loosening function. The design uses a clamping plate, a second spring and tooth grooves to form a structure similar to a ratchet mechanism. Even if vibration occurs during vehicle operation, it can effectively prevent the reverse rotation of the threaded column, ensuring that the sensor body is always firmly fixed on the vehicle body, avoiding the loosening problem that may occur with traditional fasteners.
[0022] (2) The anti-vibration and anti-loosening sensor mounting base can effectively reduce the impact of vibration on the sensor body through the compression mechanism and telescopic column structure. When vibration occurs during vehicle operation, the sensor body is compressed and extended in a small range through the action of the telescopic column and the No. 1 spring. The hydraulic oil generates damping force through the flow of the throttle hole, which effectively reduces the impact of vibration on the sensor. In addition, the rubber damping pad set on the movable ring further absorbs vibration energy and enhances the anti-vibration effect of the system. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1:
[0031] Please see Figure 1-4 The anti-vibration and anti-loosening sensor mounting base includes:
[0032] The base plate 1 has a mounting groove 2 on its bottom wall for mounting the sensor body 10, and a through groove 3 on its top wall for the sensor body 10 to pass through. A pressing mechanism is installed in the mounting groove 2.
[0033] Fastener 7 is symmetrically installed at the corner of the base plate 1. The base plate 1 has a through hole corresponding to the position of the fastener 7. A groove 8 is provided at the top of the through hole. Several inclined toothed grooves 9 are evenly provided on the side wall of the groove 8. Fastener 7 includes a cylindrical block 71. A threaded post 72 is fixed at the bottom of the cylindrical block 71. A hexagonal prism 73 is fixed at the top of the cylindrical block 71. Two sets of limiting mechanisms that cooperate with the toothed grooves 9 are symmetrically installed on the side wall of the cylindrical block 71. The limiting mechanisms and the toothed grooves 9 form a ratchet mechanism.
[0034] The cylindrical block 71 has symmetrically opened storage slots on its side walls, and the limiting mechanism is installed in the storage slots.
[0035] The limiting mechanism includes a locking plate 74, which is rotatably installed between the upper and lower walls of the storage slot. A second spring 75 is fixed between the inner wall of the locking plate 74 and the inner wall of the storage slot.
[0036] The threaded column 72 is slidably installed in the through hole, and the cylindrical block 71 is movably installed in the groove 8.
[0037] In this embodiment, the sensor body 10 is installed at a designated position on the vehicle body by means of the seat plate 1 and fastener 7. The fastener 7, with the cooperation of the tooth groove 9, can prevent reverse rotation after tightening, thereby achieving the purpose of preventing loosening. The compression mechanism can press the sensor body 10 at the designated position on the vehicle body during the installation process of the seat plate 1, and at the same time, the compression mechanism can achieve the function of shock absorption and buffering.
[0038] When fastener 7 is installed on the seat plate 1, a wrench is used to rotate the entire fastener 7 by gripping the outside of the hexagonal prism 73, screwing the threaded post 72 into the threaded hole of the vehicle body. When the cylindrical block 71 moves to the position of the groove 8, the retaining plates 74 on both sides are manually pushed into the receiving groove to prevent the retaining plates 74 from obstructing the downward movement of the fastener 7, until the bottom end of the cylindrical block 71 enters the groove 8. At this time, the retaining plates 74 are released, and the hexagonal prism 73 is rotated until the fastener 7 firmly fixes the seat plate 1 to the vehicle body. The retaining plates 74, under the action of the second spring 75, are engaged in the nearest toothed groove 9. The retaining plates 74, the second spring 75, and the toothed groove 9 combine to form a structure similar to a ratchet mechanism, such as... Figure 4 As shown, the fastener 7 can rotate smoothly when tightened counterclockwise, but will get stuck when tightened clockwise. When the threaded post 72 is vibrated and reverses, the clamping plate 74 will abut against the tooth groove 9 to prevent the threaded post 72 from reversing, thereby achieving the purpose of preventing loosening.
[0039] Example 2:
[0040] Please see Figure 2-5 This embodiment provides a technical solution based on Embodiment 1:
[0041] The extrusion mechanism includes a movable ring 4, and several telescopic columns 5 are symmetrically fixed on the top wall of the movable ring 4;
[0042] The top of the telescopic column 5 is fixedly connected to the top wall of the mounting groove 2, and a No. 6 spring is sleeved on the outside of the telescopic column 5.
[0043] Spring 6 is fixed between the top wall of the movable ring 4 and the top wall of the mounting groove 2.
[0044] A rubber damping pad is glued to the contact position between the bottom wall of the movable ring 4 and the sensor body 10.
[0045] The telescopic column 5 includes a sleeve 51, which is fixed to the top wall of the movable ring 4. The sleeve 51 is filled with hydraulic oil 54, and a piston 52 is slidably installed inside the sleeve 51.
[0046] The piston 52 has several throttling holes 55 symmetrically opened on its body, and a movable column 53 is fixed in the center of the top wall of the piston 52.
[0047] The top of the movable column 53 slides through the top wall of the sleeve 51 and is fixedly connected to the top wall of the mounting groove 2.
[0048] In this embodiment, the compression mechanism can press the sensor body 10 into a designated position on the vehicle body during the installation of the seat plate 1, and at the same time, the compression mechanism can achieve shock absorption. In the initial state, the bottom wall of the movable ring 4 is flush with the bottom wall of the seat plate 1. When installing the sensor body 10, the fastener 7 installs the seat plate 1 on the vehicle body. At this time, the side of the sensor body 10 will press the movable ring 4 into the mounting groove 2. At this time, the first spring 6 is compressed. After the seat plate 1 is installed, the sensor body 10 adheres to the vehicle body under the reaction force of the first spring 6, completing the installation of the sensor body 10. Meanwhile, when vibration occurs during vehicle movement, the sensor body 10 slightly compresses the telescopic column 5 and the first spring 6. During the compression and stretching of the telescopic column 5, the piston 52 moves along the inner wall of the sleeve 51. At this time, the hydraulic oil 54 in the sleeve 51 flows up and down through the throttle hole 55 on the piston 52. During the flow, the friction between the hydraulic oil 54 and the hole wall of the throttle hole 55 and the internal friction between molecules form a damping force, which hinders the movement of the piston 52, thereby reducing vibration. At the same time, the rubber damping pad set on the moving ring 4 can further absorb the energy generated by the vibration and achieve the anti-vibration function.
