Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically, to a vehicle-mounted T-BOX and gateway integrated heat dissipation structure, method, and vehicle based on air conditioning bypass. Background Technology

[0002] The in-vehicle T-BOX, also known as a vehicle networking system, mainly consists of four parts: a host unit, the in-vehicle T-BOX, a mobile app, and a backend system. The host unit is mainly used for in-vehicle audio-visual entertainment and vehicle information display. The in-vehicle T-BOX is mainly used to communicate with the backend system / mobile app to realize vehicle information display and control via the mobile app. The gateway refers to the interconnection device that enables network interconnection at the transmission layer. For the in-vehicle T-BOX to communicate with the backend system / mobile app, a gateway must be installed as a prerequisite. Currently, most in-vehicle T-BOXs and gateways are set up separately. When set up separately, since both the T-BOX and the gateway have external casings, the two casings occupy a lot of space. In addition, wiring is required externally, resulting in numerous wires and inconvenience to users. Currently, many car manufacturers have conducted in-depth research on integrating the in-vehicle T-BOX and gateway into a single device to reduce space occupation and external wiring hassles.

[0003] Chinese patent application CN113895211A discloses a control device, method, and air conditioner for an automotive air conditioner. The device includes: a data acquisition unit configured to acquire the current level of condensate in the drip tray and the vehicle's speed and acceleration during operation of the vehicle; a control unit configured to determine the road surface smoothness based on gravitational acceleration, vehicle speed, and acceleration; and to control the start or stop of a DC water pump based on the current level of condensate in the drip tray and the road surface smoothness to adjust the current level of condensate in the drip tray. This solution, by regulating the amount of condensate in the drip tray of the automotive air conditioner, prevents leakage of the air conditioner during vehicle operation.

[0004] Patent CN116638928A discloses an air conditioning outlet temperature control device and control method, and an automobile, relating to the field of automotive air conditioning accessories technology. The device, located within an air conditioning outlet duct, includes a first blade and a second blade. The first blade is rotatably mounted on one side of the air conditioning outlet duct; the second blade is rotatably mounted on the other side. By rotating the first blade and / or the second blade to a set position, the diameter of the air inlet and outlet sides of the air conditioning outlet duct is adjusted. This invention, through the coordinated rotation of the first and second blades, forms a gas channel with varying diameter at the air conditioning outlet, causing changes in gas velocity and generating a temperature difference as the gas flows through, thereby accelerating the cooling or heating speed of the vehicle's air conditioning system. It also provides an automatic operating procedure for controlling the air conditioning outlet temperature control device, facilitating user operation. Automobiles equipped with this device experience faster cooling or heating inside the vehicle, reducing user waiting time.

[0005] While the aforementioned technical solutions have their respective advantages, integrating the vehicle-mounted T-BOX and gateway into a single device presents challenges. Due to the significant heat dissipation of the T-BOX and gateway, relying solely on individual fans for cooling may not achieve optimal results. Therefore, utilizing the air conditioning system as the vehicle's cooling system, by directing a portion of the cool air to the T-BOX and gateway for heat dissipation, offers a portability advantage. In light of this, we propose a heat dissipation structure, method, and vehicle based on an air conditioning bypass for the integrated cooling system of the vehicle-mounted T-BOX and gateway. Summary of the Invention

[0006] The purpose of this invention is to provide a heat dissipation structure, method, and vehicle based on an air conditioning bypass-in-vehicle T-BOX and gateway integration, in order to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] One objective of this invention is to provide a fusion heat dissipation structure for an in-vehicle T-BOX and gateway based on an air conditioning bypass, comprising an outer frame plate and a support plate disposed below the outer frame plate. An in-vehicle T-BOX motherboard is fixedly mounted at the center of the outer frame plate, and a gateway motherboard is fixedly mounted at the center of the support plate. A central bracket is provided between the outer frame plate and the support plate, and a wiring hole is provided at the center of the central bracket for electrical connection between the in-vehicle T-BOX motherboard and the gateway motherboard. A fixing ring is fixedly mounted on one side of the central bracket, and a fan is fixedly mounted on the inner wall of the fixing ring for heat dissipation between the in-vehicle T-BOX motherboard and the gateway motherboard.

[0009] As a preferred embodiment of the present invention, guide sleeves are fixedly installed at the four corners of the central support, and the central support is located at half the height of the guide sleeves. The two ends of the guide sleeves are respectively inserted and engaged with the outer frame plate and the support plate to support the central support, so that the central support will not squeeze the electronic components on the vehicle T-BOX motherboard and the gateway motherboard and cause damage.

[0010] As a preferred embodiment of the present invention, the support plate is provided with a lower cover on its exterior. The outer frame plate, the support plate, and the corresponding guide sleeve are fixedly installed on the bottom surface of the lower cover by the same fastening screw for fixed installation operation and normal assembly and use.

[0011] As a preferred embodiment of the present invention, a plurality of heat dissipation fins are fixedly installed on the bottom wall of the lower cover in a linear and equidistant arrangement. The end plates of the heat dissipation fins extend to the outside of the lower cover. The number of heat dissipation fins is 10 to 30, and the distance between two adjacent heat dissipation fins is 2 mm to 4 mm, which facilitates the use of heat dissipation fins for heat dissipation between the lower cover and the gateway motherboard.

[0012] As a preferred embodiment of the present invention, temperature sensors are fixedly installed on both the inner wall and the outer surface of the lower cover. The two temperature sensors are used to measure the temperature inside and outside the lower cover, respectively, so as to facilitate real-time monitoring of the temperature inside and outside the lower cover.

[0013] As a preferred embodiment of the present invention, the left and right side plates of the lower cover are provided with first heat dissipation holes that communicate with the outside. An external pipe is fixedly installed on the front plate of the lower cover. An air inlet pipe is connected to the flange at the end of the external pipe. A tee pipe is fixedly installed at the end of the air inlet pipe. A tee valve is fixedly installed on the tee pipe. An air conditioning duct for connecting to the vehicle's air conditioning duct is fixedly installed on one of the tee pipes. An air hood for conveying outside air is fixedly installed on the remaining tee pipe, so that the air conditioning duct or outside cold air can be introduced for heat dissipation by changing the connection of the tee pipe.

[0014] As a preferred embodiment of the present invention, an air hood fixing frame is fixedly installed at the end of the air hood, and a dust filter is detachably connected inside the air hood fixing frame. The dust filter is used to filter the air so that dust does not enter the vehicle T-BOX motherboard and gateway motherboard.

[0015] As a preferred embodiment of the present invention, a lower limiting frame is fixedly installed on the top shell of the lower cover, and an upper cover is provided above the lower cover. Second heat dissipation holes for ventilation and heat dissipation are provided on both the left and right side plates of the upper cover. Multiple heat dissipation fins arranged linearly and at equal intervals are fixedly installed on the top plate of the upper cover. The distance between two adjacent heat dissipation fins is 3mm to 6mm, and the number of heat dissipation fins is 10 to 30. The number of second heat dissipation holes on each side is 3 to 6. An upper limiting frame is fixedly installed on the shell of the upper cover. The upper limiting frame and the lower limiting frame are fixedly connected by multiple fastening screws, facilitating heat dissipation using the second heat dissipation holes and heat dissipation fins. Furthermore, the upper and lower limiting frames facilitate fixed installation.

[0016] The second objective of this invention is to provide a heat dissipation method for a vehicle-mounted T-BOX and gateway integrated heat dissipation structure based on air conditioning bypass, including the aforementioned vehicle-mounted T-BOX and gateway integrated heat dissipation structure based on air conditioning bypass. The heat dissipation method includes the following steps:

[0017] S1. Temperature detection: The temperature outside the lower cover is detected by a temperature sensor located outside the lower cover, and the temperature inside the lower cover is detected by a temperature sensor located inside the lower cover. During the temperature detection process, the following two situations may occur: one is that the temperature outside the lower cover is lower than the temperature inside the lower cover, and the other is that the temperature outside the lower cover is higher than the temperature inside the lower cover.

[0018] S2. If the temperature outside the lower cover is lower than the temperature inside the lower cover, open the three-way valve to connect the air hood with the air inlet pipe, then start the fan to make the fan work, so as to deliver the low-temperature outside air to the space between the upper and lower covers to dissipate heat from the vehicle T-BOX motherboard and gateway motherboard. The heat is discharged outward through the first and second heat dissipation holes.

[0019] S3. If the temperature outside the lower cover is greater than the temperature inside the lower cover, and the temperature inside the lower cover still exceeds the standard value even with the fan working to dissipate heat, the three-way valve opens to connect the air conditioning duct and the air intake duct. If the vehicle's air conditioning system is already on, the air conditioning duct connects to the pipes in the vehicle's air conditioning system, and a suitable amount of cold air from the vehicle's air conditioning system enters the lower cover through the air conditioning duct and the air intake duct to work with the fan to dissipate heat. If the vehicle's air conditioning system is not on, the temperature inside the lower cover exceeding the standard value is transmitted to the vehicle's central control unit in real time. The vehicle's central control unit automatically turns on the vehicle's air conditioning system and closes the air ducts entering the vehicle's interior from the air conditioning system for cooling.

[0020] A third objective of this invention is to provide an automobile, including the aforementioned integrated heat dissipation structure of the vehicle-mounted T-BOX and gateway based on air conditioning bypass, and a connecting component for mounting and connecting the integrated heat dissipation structure of the vehicle-mounted T-BOX and gateway based on air conditioning bypass.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention can perform heat dissipation operation normally through the first heat dissipation hole and the second heat dissipation hole, and can perform heat conduction operation through the heat dissipation fins and heat sink, so as to achieve the effect of heat dissipation and heat conduction.

[0023] 2. This invention uses a central support and a fan to separate the vehicle-mounted T-BOX motherboard and the gateway motherboard by a certain distance, so that the vehicle-mounted T-BOX motherboard and the gateway motherboard will not interfere with each other. In addition, the operation of the fan can perform heat dissipation and improve the heat dissipation effect.

[0024] 3. Through the configuration of components such as the three-way pipe, this invention can deliver an appropriate amount of cold air from the vehicle's air conditioning system to the space between the lower and upper covers for cooling and heat dissipation, thereby achieving a better heat dissipation effect.

[0073] S2. If the temperature outside the lower cover 4 is lower than the temperature inside the lower cover 4, open the three-way valve 451 to connect the air shroud 47 with the air inlet pipe 44. At this time, the air conditioning cold air pipe 46 is not connected to the air inlet pipe 44. Then start the fan 33 to make the fan 33 work. After the fan 33 works, the low temperature outside air is transported through the air shroud 47 and the air inlet pipe 44 to the space between the upper cover 5 and the lower cover 4 to dissipate heat from the vehicle T-BOX motherboard 10 and the gateway motherboard 20. The heat is discharged outward through the first heat dissipation hole 42 and the second heat dissipation hole 50.

[0074] S3. If the temperature outside the lower cover 4 is greater than the temperature inside the lower cover 4, and the temperature inside the lower cover 4 still exceeds the standard value under the condition that the fan 33 is working normally for heat dissipation, then the three-way valve 451 opens to connect the air conditioning cold air pipe 46 and the air intake pipe 44. If the vehicle's internal air conditioning system is already on, then the air conditioning cold air pipe 46 is connected to the pipes in the vehicle's air conditioning system. A suitable amount of cold air from the vehicle's air conditioning system enters the lower cover 4 along the air conditioning cold air pipe 46 and the air intake pipe 44 and works with the fan 33 to dissipate heat. If the vehicle's internal air conditioning system is not on, the temperature inside the lower cover 4 that exceeds the standard value is transmitted to the vehicle's central control host in real time. The vehicle's central control host automatically turns on the vehicle's air conditioning system and closes the air pipes in the air conditioning system that enter the vehicle's interior for cooling. The closure of the air pipes inside the vehicle ensures that the air from the air conditioning system will not enter the passenger compartment. When the air conditioning system needs to be turned on while the vehicle is in motion, the air conditioning cold air pipe 46 still provides a suitable amount of air intake, which will not affect the normal airflow into the passenger compartment.

[0075] Finally, it should be noted that the vehicle-mounted T-BOX motherboard 10, gateway motherboard 20, fan 33, three-way valve 451, vehicle air conditioning system, vehicle central control host and central control display screen, etc. involved in this invention are all general standard parts or parts known to those skilled in the art.
