Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning compressor technology, and in particular to an anti-loosening automotive air conditioning compressor controller. Background Technology

[0002] During the operation of an automotive air conditioning system, the compressor and controller are core components that need to be stably installed and efficiently cooled to ensure the normal operation of the system. In the existing technology, some automotive air conditioning compressors and controllers adopt an integrated installation structure, which makes it easy for the high temperature generated by the compressor to be directly conducted to the controller. The controller itself also generates heat during operation. The superposition of the two heats will cause the temperature of the core components to rise, exceeding the normal operating temperature range, shortening the service life, or even causing failure.

[0003] For example, the patent publication number "CN219727804U" describes an installation structure for an electric vehicle air conditioning compressor and compressor controller. This patent installs the compressor controller at the rear of the compressor body, and a low-temperature refrigerant inflow area is set at the rear of the compressor. By utilizing the heat dissipation characteristics of the low-temperature refrigerant area, the problem of heat conduction between the compressor and controller in traditional integrated installation is solved. At the same time, this structure adopts an independent installation method, which allows the compressor and controller to be disassembled and repaired separately, and the overall size is small, reducing the installation space requirement.

[0004] However, in the aforementioned patent, the compressor controller is directly installed at the rear of the compressor via a locking screw, without any auxiliary structure for buffering or preventing loosening due to vibration. High-frequency vibrations during vehicle operation are directly transmitted to the locking screw, which can easily cause the screw to loosen after long-term use, leading to displacement of the controller, affecting the stability of the connection with the compressor, and even posing a risk of the controller falling off. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-loosening automotive air conditioning compressor controller, which solves the problem in the above-mentioned patent where the compressor controller is directly installed at the rear of the compressor by a locking screw without a buffer or anti-vibration loosening auxiliary structure. High-frequency vibrations during vehicle operation are directly transmitted to the locking screw, which is prone to loosening after long-term use, causing the controller to shift, affecting the connection stability with the compressor, and even causing the controller to fall off.

[0006] To achieve the above objectives, this utility model provides an anti-loosening automotive air conditioning compressor controller, including a mounting frame, a controller body, and a compressor body. The mounting frame is provided with a mounting protection mechanism for mounting and protecting the controller body and the compressor body. The mounting frame is provided with a heat dissipation mechanism for cooling the controller body and the compressor body. The mounting protection mechanism includes a rubber pad, which is mounted on the top of the mounting frame.

[0007] The mounting frame has a support plate fixedly connected to its upper surface, a rubber pad fixedly connected to the upper surface of the support plate, a connecting plate placed on the upper surface of the rubber pad, and the connecting plate fixedly connected to the upper surface of the rubber pad by bolts.

[0008] The controller body is fixedly connected to the upper surface of the connecting plate. There are two rubber pads. A connecting frame is placed on the upper surface of the other rubber pad. The connecting frame is fixedly connected to the upper surface of the other rubber pad by bolts. The compressor body is fixedly connected to the inner wall surface of the connecting frame.

[0009] The mounting frame has a protective box that is slidably connected to its surface. The protective box is fixedly connected to the mounting frame surface by bolts, and a dustproof net is fixedly connected to the upper surface of the protective box.

[0010] The mounting frame is fixedly connected to a connecting frame on one side, a water tank is fixedly connected to a connecting frame on one side, a water pump is fixedly connected to a mounting frame on one side, and the water pump is fixedly connected to a side of the water tank.

[0011] A circulation pipe is fixedly connected to one side of the inner wall of the mounting frame. The circulation pipe passes through one side of the mounting frame and is fixedly connected to the water pump. A fan is fixedly connected to the inner wall surface of the mounting frame.

[0012] This utility model discloses an anti-loosening automotive air conditioning compressor controller. By setting a protective mounting mechanism above the mounting frame, and utilizing the elastic cushioning properties of rubber pads, the controller body and compressor body are indirectly mounted on the mounting frame via connecting plates and connecting brackets. The rubber pads absorb vibrations during vehicle operation, preventing direct transmission of vibrations to the connecting bolts and thus preventing loosening. Simultaneously, the rubber pads and bolts work together to achieve double fixation, effectively preventing the controller body and compressor body from loosening. Furthermore, a sliding protective box on the mounting frame provides physical protection for the controller body and compressor body, blocking external dust and moisture intrusion. The dustproof net on the protective box ensures airflow and prevents the protective structure from affecting heat dissipation. The heat dissipation mechanism inside the mounting frame uses a water pump to drive the coolant in the water tank to flow in the circulation pipe, combined with a fan to accelerate air circulation, ensuring that cool air continuously acts on the controller body and compressor body, achieving an active and stable heat dissipation effect unaffected by fluctuations in external ambient temperature or refrigerant temperature, further ensuring long-term stable operation of the components.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-5 A type of anti-loosening automotive air conditioning compressor controller includes a mounting frame 1, a controller body 205, and a compressor body 206. A mounting protection mechanism 2 is provided above the mounting frame 1 for mounting and protecting the controller body 205 and compressor body 206. A heat dissipation mechanism 3 is provided inside the mounting frame 1 for cooling the controller body 205 and compressor body 206. The mounting protection mechanism 2 includes a rubber pad 202, which is installed above the mounting frame 1. The mounting frame 1 serves as the supporting foundation for the entire device. Its upper area is specifically used for the mounting protection mechanism 2, while its lower and side areas are used to integrate the heat dissipation mechanism 3. This ensures both the installation stability of the controller body 205 and compressor body 206 and that the heat dissipation function does not conflict with the installation structure. The core component of the mounting protection mechanism 2, the rubber pad 202, is directly installed above the mounting frame 1, achieving the basic function of preventing loosening through both physical buffering and fixing.

[0022] Furthermore, a support plate 201 is fixedly connected to the upper surface of the mounting frame 1, and a rubber pad 202 is fixedly connected to the upper surface of the support plate 201. A connecting plate 203 is placed on the upper surface of the rubber pad 202, and the connecting plate 203 is fixedly connected to the upper surface of the rubber pad 202 by bolts. The support plate 201 provides stable support for the rubber pad 202, and the bolt connection can ensure the fixing strength between the connecting plate 203 and the rubber pad 202. At the same time, the elasticity of the rubber pad 202 can offset the impact of vibration on the bolts.

[0023] Furthermore, the controller body 205 is fixedly connected to the upper surface of the connecting plate 203. There are two rubber pads 202. A connecting frame 204 is placed on the upper surface of the other rubber pad 202. The connecting frame 204 is fixedly connected to the upper surface of the other rubber pad 202 by bolts. The compressor body 206 is fixedly connected to the inner wall surface of the connecting frame 204. The two rubber pads 202 correspond to the installation of the controller body 205 and the compressor body 206 respectively, realizing independent installation of the two and synchronous anti-loosening. The frame structure of the connecting frame 204 can be adapted to the shape of the compressor body 206, improving the installation stability.

[0024] Furthermore, a protective box 207 is slidably connected to the surface of the mounting frame 1. The protective box 207 is fixedly connected to the surface of the mounting frame 1 by bolts. A dustproof net 208 is fixedly connected to the upper surface of the protective box 207. The protective box 207 can slide and adjust its position along the mounting frame 1 for easy installation and maintenance. The bolt fixing ensures that the protective box 207 does not shift while the vehicle is in motion. The dustproof net 208 blocks dust while ensuring the airflow required for heat dissipation.

[0025] Furthermore, a connecting frame 301 is fixedly connected to one side of the mounting frame 1, a water tank 302 is fixedly connected to one side of the connecting frame 301, and a water pump 303 is fixedly connected to one side of the mounting frame 1. The water pump 303 is fixedly connected to one side of the water tank 302. The connecting frame 301 provides mounting support for the water tank 302. The water tank 302 stores coolant, and the water pump 303 provides power for the circulation of coolant, ensuring the continuous operation of the heat dissipation mechanism 3.

[0026] Furthermore, a circulation pipe 304 is fixedly connected to one side of the inner wall of the mounting frame 1. The circulation pipe 304 passes through one side of the mounting frame 1 and is fixedly connected to the water pump 303. A fan 305 is fixedly connected to the inner wall surface of the mounting frame 1. The circulation pipe 304 is arranged close to the inner wall of the mounting frame 1 to maximize the contact area with air. The fan 305 accelerates the air flow, so that the air cooled by the circulation pipe 304 quickly covers the controller body 205 and the compressor body 206, thereby improving the heat dissipation efficiency.

[0027] The complete working process is as follows: First, fix the support plate 201 to the upper surface of the mounting frame 1. Then, attach the two rubber pads 202 to the designated positions on the support plate 201. Fix the controller body 205 to the connecting plate 203 with bolts, and then fix the connecting plate 203 to one of the rubber pads 202 with bolts. Place the compressor body 206 on the inner wall of the connecting bracket 204 and fix it with bolts. Then, fix the connecting bracket 204 to the other rubber pad 202 with bolts. Finally, slide the protective box 207 along the surface of the mounting frame 1 to cover the controller body 205 and the compressor body 206, and fix the protective box 207 to the mounting frame 1 with bolts to complete the installation. When the car air conditioning system is powered on and started, the controller body 205 first enters the working state and sends an operating command to the compressor body 206 through a preset program. The compressor body 206 then starts and begins to compress the refrigerant. At the same time, the car air conditioning control module sends a signal to the heat dissipation mechanism 3, and the water pump 303 and the fan 305 are synchronously powered on and enter the heat dissipation preparation state. When the water pump 303 is running, it draws coolant from the water tank 302 into the circulation pipe 304 through the inlet pipe. The coolant flows along a predetermined path on the inner wall of the mounting frame 1 along the circulation pipe 304. During this flow, the coolant absorbs heat from the surrounding area of ​​the mounting frame 1, and also absorbs heat transferred to the mounting frame 1 by the controller body 205 and the compressor body 206 through the support plate 201, causing its own temperature to gradually rise. At the same time, the fan 305 operates at high speed, generating directional airflow. The airflow first passes over the surface of the circulation pipe 304, and after exchanging heat with the low-temperature circulation pipe 304, its temperature decreases, forming cold air. Driven by the fan 305, the cold air flows upward and covers the surfaces of the controller body 205 and the compressor body 206, quickly carrying away the heat generated during their operation, keeping the temperature of the controller body 205 and the compressor body 206 within their normal operating range. The coolant, having absorbed heat, continues to flow along the circulation pipe 304 and finally returns to the water tank 302 through the return pipe, completing one heat dissipation cycle. The water tank 302 can dissipate the heat absorbed by the coolant into the air through airflow during vehicle operation or its own radiator, reducing the coolant temperature to its initial state and preparing for the next cycle. The entire cooling process is continuous. Based on the temperature changes of the controller body 205 and the compressor body 206, the vehicle's air conditioning control module can dynamically adjust the speed of the water pump 303 and the fan speed of the fan 305 to achieve on-demand cooling and improve energy efficiency. During vehicle operation, vibrations from road bumps are transmitted through the vehicle body to the mounting frame 1. The mounting frame 1 then transmits the vibrations to the support plate 201. The rubber pad 202 on the support plate 201 provides elastic cushioning. The rubber pad 202 absorbs vibration energy through its own deformation, converting high-frequency vibrations into low-frequency deformation, preventing direct transmission of vibrations to the fixing bolts of the connecting plate 203 and the connecting bracket 204, and reducing the tendency for the bolts to loosen due to vibration.As a physical protective barrier, the protective box 207 can block dust, sand, rainwater and other impurities in the external environment from entering the working area of ​​the controller body 205 and the compressor body 206. The dust raised during operation is intercepted by the dustproof net 208, which prevents dust from adhering to the circuit board of the controller body 205 or the heat sink of the compressor body 206, and prevents the heat dissipation effect from being affected or the circuit from being short-circuited due to dust accumulation.
