[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a high-efficiency heat dissipation connection structure for hybrid vehicle engines, which has the following beneficial effects:
[0017] This high-efficiency heat dissipation connection structure for hybrid vehicle engines utilizes auxiliary fixing devices, fixed half-rings, and limiting devices. Through internal threaded connections and external clamping—specifically, a bidirectional screw-driven moving block—the fixed half-ring clamps the cooling circulation pipe, forming a robust internal and external double-fixing structure. This significantly enhances the stability of the entire component during vehicle operation. Adjusting and clamping the fixed half-rings requires only rotating the drive shaft. The limiting device includes an iron block and a magnet. When two sets of fixed half-rings approach each other, the magnet attracts the iron block, automatically guiding them closer until they make close contact and form a stable magnetic connection. This design not only adds additional fixing points but also further enhances the overall structural stability. More stable and accurate temperature monitoring helps the vehicle control system more rationally adjust the cooling strategy, improving engine heat dissipation efficiency.
[0018] This high-efficiency heat dissipation connection structure for hybrid vehicle engines features a locking device. After the bidirectional screw is adjusted to the correct position, the locking device achieves mechanical locking through the toothed engagement between the locking plate and the chuck. This prevents the drive shaft from rotating due to vibration or impact during vehicle operation and avoids the fixed half-ring from loosening. After adjustment, the user only needs to manually rotate the locking plate to the groove position of the chuck to complete the locking. No complicated tools or extra steps are required, which improves the convenience and efficiency of on-site operation.
[0019] This high-efficiency heat dissipation connection structure for hybrid vehicle engines features a rotating device that allows two sets of adjusting seats to rotate freely within a certain range around the central axis of the fixed seat. This enables flexible adjustment of the temperature sensor angle according to the actual installation environment, avoiding limitations caused by the initial installation angle of the threaded column.

Detailed Implementation
[0025] 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.
[0026] Please see Figures 1-4A high-efficiency heat dissipation connection structure for a hybrid electric vehicle engine includes a cooling circulation pipe 1, a temperature sensor 2, a mounting base 3, a threaded post 4, a sensing element 5, a rotating device, an auxiliary fixing device, and a limiting device. The cooling circulation pipe 1 has a threaded hole 6 at its top. The mounting base 3 is mounted on the bottom wall of the temperature sensor 2. The threaded post 4 is mounted on the bottom wall of the mounting base 3. The sensing element 5 is mounted on the bottom end of the threaded post 4. An adjusting seat 7 is rotatably mounted on the outer wall of the mounting base 3. A groove 8 is formed on the bottom wall of the adjusting seat 7. Two sets of fixing half-rings 9 are symmetrically installed in the groove 8 via the auxiliary fixing device. The limiting device is installed at the end of each set of fixing half-rings 9 away from the mounting base 3. In this embodiment, the threaded hole 6 at the top of the cooling circulation pipe 1 accurately reflects the actual temperature of the coolant. During use, the entire assembly, i.e., the temperature sensor 2, is aligned with the threaded hole 6 on the cooling circulation pipe 1, and the threaded post 4 is screwed into the threaded hole 6 to complete the installation. Then, the adjusting seat 5 is adjusted using the rotating device. The seat 7 is adjusted to a position parallel to the cooling circulation pipe 1. Then, using the auxiliary fixing device, the two sets of fixing half rings 9 are moved inward from both ends. These fixing half rings 9 can be adjusted to adapt to cooling circulation pipes 1 of different diameters to ensure a tight fit. Finally, a limit device is installed at the end of the two sets of fixing half rings 9 away from the fixing seat 3 to ensure that they will not easily loosen or shift, thereby ensuring the stability and measurement accuracy of the sensor. Since the sensing element 5 is in direct contact with the coolant, it can provide the most accurate temperature reading, which helps to control the engine's operating temperature more effectively and achieve efficient heat dissipation of the engine radiator. The rotating adjustment frame can also be adjusted to a suitable angle after the threaded column 4 and threaded hole 6 are threaded. Furthermore, the two sets of fixing half rings 9 provide auxiliary fixation to the outer wall of the cooling circulation pipe, further improving the structural stability of the temperature sensor 2 and preventing the single threaded connection from becoming loose. (The electrical connection method of the temperature sensor 2 is a well-known technology to those skilled in the art and will not be described in detail here.)
[0027] Preferably, in this embodiment, the auxiliary fixing device includes a bidirectional screw 10, a moving block 11, a drive shaft 12, and a locking device. The bidirectional screw 10 is rotatably installed inside the adjusting seat 7. The moving blocks 11 are threaded onto both the left and right ends of the bidirectional screw 10. The fixing half-rings 9 are installed on the bottom walls of both sets of moving blocks 11. The drive shaft 12 is installed through the side wall of the adjusting seat 7 at one end of the bidirectional screw 10. The locking device is installed on the outer wall of the drive shaft 12. The temperature sensor 2 has been screwed into the threaded hole 6 at the top of the cooling circulation pipe 1 through the threaded post 4. The sensing element 5 is inserted into the coolant channel. At this time, the two sets of fixing half-rings 9 are in an open state and have not yet adhered to the outer wall of the cooling circulation pipe 1. Rotating the drive shaft 12 drives the bidirectional screw 10 to rotate synchronously. After the bidirectional screw 10 rotates, the moving blocks 11 on both sides move towards each other under the action of its threads, that is, they move closer to the middle. As the moving blocks 11 approach, the two sets of fixed half rings 9 installed at their bottom also gradually close, and finally tightly fit and clamp the outer wall of the cooling circulation pipe 1. This clamping force can effectively enhance the connection stability between the entire temperature sensor 2 assembly and the cooling circulation pipe 1. When the fixed half rings 9 reach the ideal clamping state, the locking device is used to lock the drive shaft 12 in the current position. The auxiliary fixing device clamps the cooling circulation pipe 1 through the double fixed half rings 9 on both sides, forming a "double fixing inside and outside" structure (internal thread + external clamping), which greatly enhances the stability of the temperature sensor 2 in vehicle operation, and is especially suitable for the vibration environment of frequent start-stop, high-speed driving or complex road conditions of hybrid vehicles.
[0028] Preferably, in this embodiment, the engaging device includes a chuck 13, a support base 14, and a locking plate 15. The support base 14 is installed on the side wall of the adjusting seat 7 near the drive shaft 12. The locking plate 15 is rotatably installed on the side wall of the support base 14. The locking plate 15 and the chuck 13 are engaged. The chuck 13 rotates synchronously with the drive shaft 12. When the drive shaft 12 rotates to a specific position, the locking plate 15 is manually matched and engaged with the toothed groove 8 on the chuck 13, thereby preventing the drive shaft 12 from rotating further or loosening in the opposite direction. Once the locking plate 15 and the chuck 13 are successfully engaged, the entire auxiliary fixing device enters a locked state, and the bidirectional screw 10 will not be accidentally released, maintaining the stable clamping of the fixing half ring 9 on the cooling circulation pipe 1. The engaging device ensures that the fixing half ring 9 always maintains a tight clamping of the cooling circulation pipe 1, enhancing the stability and reliability of the overall structure.
[0029] Preferably, in this embodiment, a knob 16 is installed at the end of the drive shaft 12. The drive shaft 12 is manually rotated by the knob 16, making it simpler and more direct for the bidirectional screw 10 to drive the moving block 11 and the fixed half ring 9 to clamp or loosen. Adjustment can be completed without additional tools, which is convenient and quick.
[0030] Preferably, in this embodiment, the limiting device includes an iron block 17 and a magnet 18. The iron block 17 and the magnet 18 are respectively installed at the ends of the two sets of fixed half rings 9 away from the fixed base 3. The magnet 18 and the iron block 17 are magnetically connected. When the two sets of fixed half rings 9 approach each other, the magnet 18 attracts the iron block 17, automatically guiding them to approach each other until they are in close contact and form a stable magnetic connection. Once the iron block 17 and the magnet 18 are successfully magnetically connected, the attraction between them will keep the position of the fixed half ring 9 unchanged, and they will not easily loosen even if they encounter vibration or impact during vehicle operation.
[0031] Preferably, in this embodiment, the rotating device includes a groove 19 and a slider 20. The side wall of the fixed seat 3 is provided with an annular groove 19, and the slider 20 is slidably installed in the groove 19. The side wall of the slider 20 is fixedly connected to the side wall of the adjusting seat 7. When it is necessary to adjust the angle or position of the adjusting seat 7 relative to the temperature sensor 2, the operator can manually rotate the adjusting seat 7. Since the slider 20 is restricted to move within the annular groove 19, the adjusting seat 7 can only rotate along the direction of the groove 19 (i.e., around the central axis of the fixed seat 3). As the adjusting seat 7 rotates, the slider 20 slides smoothly along the groove 19, ensuring the smoothness and accuracy of the entire adjustment process. This design allows the adjusting seat 7 to rotate freely within a certain range in order to find the optimal auxiliary fixing angle and prevent it from being affected by the installation angle of the threaded column 4.
[0032] Preferably, in this embodiment, both the slider 20 and the slide groove 19 are T-shaped designs. The design of the T-shaped slider 20 and the T-shaped slide groove 19 can effectively prevent the slider 20 from coming out of the slide groove 19, play a certain limiting role, and ensure the normal angle adjustment action of the adjusting seat 7.
[0033] Preferably, in this embodiment, the adjusting seat 7 and the internal components are provided in two sets via the rotating device. By setting the adjusting seat 7 and the corresponding fixing components at both ends of the cooling circulation pipe 1, a stable clamping force can be provided at two positions, avoiding the instability of single-point fixing. This ensures that the temperature sensor 2 can maintain a firm position throughout the entire service life.
