Description

Technical Field

[0001] This utility model relates to a protective housing, and more particularly to a protective housing for a vehicle temperature sensor. Background Technology

[0002] During long drives, the interior temperature of a vehicle fluctuates with changes in the external ambient temperature. Vehicle temperature sensors help people monitor real-time temperature changes both inside and outside the vehicle, allowing for timely intervention to ensure comfort and safety. To ensure stable operation of the temperature sensor in various environments, a protective housing is essential.

[0003] However, the fixing methods of ordinary protective shells are usually quite simple, mostly using screws, glue or simple clips. This not only requires the mounting surface to be flat, making it difficult to adapt to the complex curves and irregular shapes inside the vehicle, but also limits the flexibility of the installation position. For users who need to use the equipment in a variety of different environments, this fixing method cannot meet their needs for quick adjustment and temporary fixing in various situations.

[0004] Therefore, there is a particular need for a protective housing for vehicle temperature sensors to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of ordinary protective housings, which have limited fixing methods, are difficult to adapt to the complex shapes inside vehicles, restrict installation flexibility, and cannot meet the needs of rapid adjustment and temporary fixing in various environments, this utility model provides a protective housing for vehicle temperature sensors.

[0006] This utility model is achieved through the following technical means: a protective housing for a vehicle temperature sensor, comprising a housing, a digital display screen, a metal probe, a wire, a cover plate, buckles, and a temperature sensor body. The digital display screen is embedded and fixed to the front part of the housing. The temperature sensor body is placed in the front part of the housing. The wire is connected to the upper right part of the temperature sensor body. The metal probe is connected to the end of the wire. The cover plate is located at the rear of the housing, with its front side closely attached to the rear side of the housing. A U-shaped groove for accommodating the wire is opened on the upper right side of the cover plate. Multiple slots are distributed in a U-shape and are opened at multiple corners of the rear part of the housing. Multiple buckles are distributed in a U-shape and fixed to multiple corners of the cover plate. The number of buckles is the same as the number of slots, and they are engaged one-to-one. The buckles have a hook-like structure with an inwardly bent barb or protrusion at the front end. The slots have a rectangular structure and are slightly wider than the buckles. The housing also includes a fixing component for fixing the housing, which is set on the upper part of the housing.

[0007] Furthermore, the fixing assembly includes a hinge block, a first bolt, a rotating seat, a second bolt, a nut, a hinge arm, a hinge seat, an adsorption disk, and a rotating plate. The rotating seat is rotatably connected to the upper part of the housing. The nut is threaded onto the thread at the front of the rotating seat, and its rear side is in close contact with the housing. The hinge block is rotatably connected to the rear of the rotating seat. The first bolt is threaded between the hinge block and the rotating seat. The hinge arm is rotatably connected to the hinge block. The hinge seat is rotatably connected to the hinge arm. Two second bolts are distributed vertically. One second bolt is threaded between the hinge block and the hinge arm, and the other second bolt is threaded between the hinge arm and the hinge seat. The adsorption disk is fixed to the hinge seat. The rotating plate is rotatably connected to the hinge seat and is located below the adsorption disk.

[0008] Furthermore, it also includes dustproof nets, multiple ventilation openings distributed on the left and right sides of the cover plate, and multiple ventilation openings distributed along a circumference form a group, forming a flower-shaped ventilation system, with each dustproof net fixed inside each ventilation opening.

[0009] Furthermore, it also includes positioning sleeves and positioning rods. Multiple positioning sleeves are distributed along a rectangular direction and fixed to multiple corners on the front side of the cover plate, close to the corresponding buckles. Multiple positioning rods are distributed along a rectangular direction and fixed to multiple corners on the front part of the housing, and are horizontally aligned with the multiple positioning sleeves for snapping. The corners of the temperature sensor body have circular grooves to accommodate the positioning rods, and the number of these grooves is the same as the number of positioning rods.

[0010] Furthermore, it also includes rubber rings, each of which is fixed to the front end of each positioning sleeve, with its front side in close contact with the rear side of the temperature sensor body.

[0011] Furthermore, it also includes a rubber pad, which is fixed to the front of the housing, and its rear side contacts the front side of the temperature sensor body. The rubber pad has circular slots for accommodating positioning rods, and the number of these circular slots is the same as the number of positioning rods.

[0012] Furthermore, it also includes a handle, which is fixed to the hinge block.

[0013] Furthermore, it also includes a protective sleeve, a hollow rectangular protective sleeve, which is fitted over the outside of the shell.

[0014] Furthermore, the buckle is made of a relatively stiff, elastic plastic.

[0015] Beneficial effects:

[0016] By improving the design of the fixing components, users can flexibly adjust the position and angle of the adsorption plate according to actual needs, adapting to complex curved surfaces and irregular shapes inside or outside the vehicle. Whether for temporary fixing or long-term installation, users can quickly complete the adjustment to meet the needs of different occasions, greatly improving the convenience and flexibility of use.

[0017] The positioning sleeve and positioning rod work together to ensure precise alignment between the cover plate and the housing, avoiding problems such as poor sealing or misalignment of the clips due to improper installation, and enhancing the connection strength between the cover plate and the housing to ensure that the cover plate will not loosen.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Example: A protective housing for a vehicle temperature sensor, such as Figures 1-7As shown, the device includes a housing 1, a digital display screen 2, a metal probe 3, a wire 31, a cover plate 4, a dustproof mesh 51, a buckle 6, a temperature sensor body 10, and a protective sleeve 19. The digital display screen 2 is glued to the front of the housing 1. The temperature sensor body 10 is placed in the front of the housing 1. The wire 31 is connected to the upper right of the temperature sensor body 10. The metal probe 3 is connected to the end of the wire 31. The cover plate 4 is located at the rear of the housing 1, with its front side tightly against the rear side of the housing 1, covering the housing 1. The upper right side of the cover plate 4 has a U-shaped groove to accommodate the wire 31 passing through, ensuring the wire... 31 will not be squeezed or damaged. Multiple vents 5 are distributed on the left and right sides of the cover plate 4, and the multiple vents 5 distributed along a circumference form a group, forming a flower-shaped ventilation system. This design is not only aesthetically pleasing, but also effectively guides airflow. When the temperature sensor body 10 generates heat, the heat is discharged from the vents 5, achieving effective heat dissipation. Each dustproof mesh 51 is connected to the inside of each vent 5 by adhesive, effectively preventing external dust and other impurities from entering the inside of the housing 1 from the cover plate 4, protecting the inside of the housing 1 from contamination. The four slots 101 are distributed in a U-shape. Located at the four corners of the rear part of the housing 1, four buckles 6 are arranged in a U-shape and are connected to the four corners of the cover plate 4 by adhesive. The number of four buckles 6 is the same as the number of four slots 101, and they are engaged one-to-one to fix the cover plate 4 to the rear part of the housing 1. The buckles 6 have a hook-shaped structure with an inwardly curved barb or protrusion at the front end, which can form a locking effect after entering the slot 101. The slot 101 has a rectangular structure, slightly wider than the buckle 6, and has a certain amount of elastic space inside so that the buckle 6 can smoothly enter and lock. The buckles 6 are made of a relatively hard elastic plastic. Made of materials such as polycarbonate or reinforced nylon, it can deform under external pressure and quickly return to its shape after the pressure is released, ensuring that the buckle 6 can be temporarily deformed when squeezed by the inner wall of the housing 1, and can accurately align with the slot 101 and return to its shape after the cover plate 4 is fully closed, and firmly snap into place. The hollow rectangular protective sleeve 19 is fitted over the outside of the housing 1, fully covering the four sides of the housing 1, providing additional physical protection to prevent the housing 1 from being hit or scratched by external collisions. It also includes a fixing component for fixing the housing 1, which is set on the upper part of the housing 1.

[0028] like Figure 1 , Figure 6 and Figure 7As shown, the fixing assembly includes a hinge block 12, a handle 121, a first bolt 122, a rotating seat 13, a second bolt 131, a nut 14, a hinge arm 15, a hinge base 16, an adsorption plate 17, and a rotating plate 18. The rotating seat 13 is rotatably connected to the upper part of the housing 1. The nut 14 is threaded onto the thread at the front of the rotating seat 13, and its rear side is in close contact with the housing 1, thus fixing the rotating seat 13 to the upper part of the housing 1. The hinge block 12 is rotatably connected to the rear of the rotating seat 13. The handle 121 is attached to the hinge block 12 by adhesive bonding, facilitating the rotation of the hinge block 12. The first bolt 122 is threaded between the hinge block 12 and the rotating seat 13, thus fixing the hinge block 12 to the rotating seat 13. The hinge arm 15 is rotatably connected to the hinge block 16. 2. The hinge seat 16 is rotatably connected to the hinge arm 15. Two second bolts 131 are distributed vertically. The lower second bolt 131 is threaded between the hinge block 12 and the hinge arm 15, so that the hinge arm 15 is fixed on the hinge block 12. The upper second bolt 131 is threaded between the hinge arm 15 and the hinge seat 16, so that the hinge seat 16 is fixed on the hinge arm 15. The adsorption plate 17 is connected to the hinge seat 16 by adhesive. The rotating plate 18 is rotatably connected to the hinge seat 16 and is located below the adsorption plate 17. The structure composed of the hinge seat 16, the adsorption plate 17 and the rotating plate 18 is similar to the working principle of a manual vacuum suction cup. The adsorption and release functions can be realized by simple mechanical operation (rotating the rotating plate 18 clockwise).

[0029] like Figures 3-5 As shown, it also includes positioning sleeves 7, rubber rings 8, positioning rods 9, and rubber pads 11. Four positioning sleeves 7 are distributed along a rectangular axis and are bonded to the four corners of the front side of the cover plate 4, close to the corresponding snap fasteners 6. Four positioning rods 9 are distributed along a rectangular axis and are bonded to the four corners of the front part of the housing 1, horizontally aligned with the four positioning sleeves 7 for snap-fit, ensuring precise alignment between the cover plate 4 and the housing 1. The temperature sensor body 10 has four circular grooves on its corners to accommodate the positioning rods 9, the number of which matches the number of positioning rods 9. Each rubber ring 8 is bonded to each positioning sleeve. The front side of the cylinder 7 is in close contact with the rear side of the temperature sensor body 10, firmly pressing the temperature sensor body 10 into the front part of the housing 1 to prevent the temperature sensor body 10 from moving. The rubber pad 11 is connected to the front part of the housing 1 by adhesive, and its rear side contacts the front side of the temperature sensor body 10. When the temperature sensor body 10 is placed inside the housing 1, the rubber pad 11 effectively isolates the direct contact between the temperature sensor body 10 and the front side of the housing 1, reducing the impact of external vibration and impact. The rubber pad 11 has four circular slots for accommodating the positioning rods 9, which is the same as the number of positioning rods 9.

[0030] When the protective housing is needed, the user first gently pries off the cover plate 4 to open the housing 1. A slight external force can be applied when prying off the cover plate 4 to disengage the latch 6 from the slot 101. Then, the temperature sensor body 10 is placed inside the housing 1, ensuring it is correctly positioned to contact the rubber pad 11. Next, the wire 31 is arranged to ensure the metal probe 3 is outside the housing 1 for temperature measurement. Then, the cover plate 4 is aligned with the rear of the housing 1. As the cover plate 4 approaches the housing 1, the latch 6 contacts the inner wall of the housing 1 and temporarily deforms, compressing into the slot 101. When the cover plate 4 covers the rear of the housing 1, the latch 6 fully reverts to its original shape and securely engages in the slot 101, locking the cover plate 4 to the housing 1. During this process, the positioning sleeve 7 engages with the positioning rod 9 to ensure precise alignment between the cover plate 4 and the housing 1. The rubber ring 8 is tightly pressed against the temperature sensor body 10, firmly holding it inside the housing 1. To prevent the temperature sensor body 10 from moving inside the housing 1, unscrew the nut 14, the first bolt 122, and the two second bolts 131 to release the fixing of the rotating seat 13, hinge block 12, hinge arm 15, and hinge seat 16. At this time, the rotating seat 13, hinge block 12, hinge arm 15, and hinge seat 16 can be rotated clockwise or counterclockwise to a suitable angle to adjust the position and angle of the adsorption plate 17. After adjustment, screw on the nut 14, the first bolt 122, and the two second bolts 131 to re-fix the rotating seat 13, hinge block 12, hinge arm 15, and hinge seat 16 to ensure the stability and reliability of the entire fixing assembly. Finally, press the adsorption plate 17 onto the surface inside the vehicle to ensure that the adsorption plate 17 is in close contact with the surface. Then rotate the rotating plate 18 clockwise to squeeze out the air inside the adsorption plate 17, so that it generates a strong adsorption force and is firmly adsorbed onto the surface. Thus, the fixing of the housing 1 is completed.

[0031] Users can choose to fix the housing 1 inside or outside the vehicle according to their actual needs. If it is installed inside the vehicle, it is recommended to choose a relatively stable area such as below the dashboard or under the seat. If it is installed outside the vehicle, the door, hood, trunk, or other locations can be selected to ensure that the temperature sensor body 10 can accurately measure the required temperature data.

[0032] It is important to note that the temperature sensor body 10 and the digital display screen 2 should be equipped with corresponding wireless modules to ensure that they can communicate through the selected wireless protocol. Common wireless protocols include Bluetooth and Wi-Fi. Users can choose the appropriate communication method according to their actual needs. When it is necessary to detect the temperature inside or outside the vehicle, the user should open the wireless settings interface of the digital display screen 2, search for and pair the temperature sensor body 10. After successful pairing, the digital display screen 2 will automatically receive the data from the temperature sensor body 10 and display the temperature value in real time. In addition, the digital display screen 2 can obtain power through the vehicle's 12V power adapter or OBD-II interface. Ensure that the power input voltage of the digital display screen 2 matches the vehicle's power supply. If necessary, use a voltage regulator or step-down module to ensure a stable power supply for the digital display screen 2.
