Description

Technical Field

[0001] This utility model relates to the field of intelligent connected vehicle technology, specifically to a door temperature control device and a vehicle. Background Technology

[0002] As a key component in the user's experience of entering and leaving the vehicle, the performance of car doors has been challenged under various environmental conditions. Especially in extreme temperature environments, such as high or low temperatures, the issue of direct contact between the user and the door components when manually opening and closing the door becomes increasingly prominent.

[0003] In cold weather, exterior door handles often freeze. This icing increases friction between the handle and the user's hand, and in severe cases, can render the handle unusable, preventing the user from opening the door. Simultaneously, in low temperatures, other parts of the door, such as button areas, may experience sluggish response or mechanical malfunctions due to the cold, affecting normal user operation. In hot weather, exterior door handles, under direct sunlight and high temperatures, can rapidly increase in surface temperature, sometimes becoming unbearably hot. This not only causes significant discomfort but can also prevent the user from quickly opening the door in an emergency, posing a safety hazard. Furthermore, most door button areas become scorching hot in hot weather, affecting the user's ability to operate door functions.

[0004] Currently, some car doors use resistance wire heated door handle technology, which alleviates the problem of door handles freezing in cold weather to some extent by utilizing the principle of resistance wire heating. However, this technology has obvious limitations: it only has a heating function and cannot deal with overheating problems in hot weather, and it lacks cooling capacity, thus failing to fully meet users' needs for comfortable use of car doors in different temperature environments. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a door temperature control device and vehicle to enhance the cooling and heating capabilities of the door interior button area and the door exterior handle, thereby improving the user's driving experience.

[0006] To solve the above-mentioned technical problems, this utility model provides a car door temperature control device, comprising:

[0007] The interior door air outlet branch circuit is connected to the main air duct inside the vehicle;

[0008] An interior air outlet branch located inside the door and connected to the interior door air outlet branch via a flexible ventilation connection component;

[0009] An air outlet pipe is connected to the air outlet branch inside the door and is used to outlet air to the door handle area outside the door and the button area inside the door, respectively.

[0010] A door air outlet damper installed on the main air duct inside the vehicle and used to control the air outlet branch to the door inside the vehicle;

[0011] A door end damper installed on the air outlet branch inside the door and used to control the air outlet to the air outlet duct.

[0012] Preferably, the flexible ventilation connection component is a flexible copper tube with an internal movable copper mesh and a movable joint.

[0013] Preferably, the air duct includes an air duct for the exterior door handle and an air duct for the interior door button area, with the exterior door handle air duct and the interior door button area air duct arranged in a herringbone pattern.

[0014] Preferably, the door end damper is located at the intersection of the air outlet pipe of the door outside handle and the air outlet pipe of the door inside button area.

[0015] Preferably, the door end damper is a controllable electronic damper that closes or opens the corresponding air outlet pipe according to its closed position;

[0016] When the air damper at the end of the door closes toward the air outlet pipe of the door outside handle, the air outlet pipe of the door outside handle is sealed.

[0017] When the air damper at the end of the door closes toward the air outlet pipe of the button area inside the door, the air outlet pipe of the button area inside the door is sealed.

[0018] When the door end vent is in the center position, open the air outlet pipe of the door outside handle and the air outlet pipe of the door inside button area.

[0019] Preferably, the main air duct inside the vehicle is a square tube structure, and the air outlet branches inside the vehicle doors, the air outlet branches inside the doors, the air outlet pipes outside the door handles, and the air outlet pipes inside the door button areas are all round tube structures.

[0020] Preferably, the in-vehicle door air outlet branch, the flexible ventilation connection component, the in-vehicle door air outlet branch, and the air outlet duct together form an air outlet path for cold air in rapid cooling mode or a air outlet path for hot air in rapid heating mode.

[0021] Preferably, the in-vehicle door air outlet branch, the flexible ventilation connection component, the in-vehicle door air outlet branch, and the in-vehicle door handle air outlet pipe together form the air outlet path for hot air in the rapid de-icing mode.

[0022] Preferably, the door temperature control device further includes: an interior air outlet damper installed downstream of the main air duct inside the vehicle, used to control the airflow into the vehicle.

[0023] This utility model also provides a vehicle, including the aforementioned door temperature control device.

[0024] The implementation of this utility model has the following beneficial effects: it significantly improves the functionality of the vehicle door under extreme weather conditions and enhances user comfort. Through an integrated door ventilation system and intelligent temperature control mechanism, the temperature of the door handles and button areas can be precisely adjusted. In high-temperature environments, the rapid cooling mode automatically adjusts the air damper to effectively reduce the temperature of the door handles and button areas, preventing users from experiencing discomfort due to overheating. In low-temperature environments, the rapid heating mode delivers hot air to prevent the door handles from freezing, ensuring smooth door operation. Furthermore, this utility model automatically closes the air ducts of the door handles after the user enters the vehicle, reducing unnecessary energy consumption. The introduction of the rapid de-icing mode, using high-speed hot airflow to quickly melt ice, further improves the vehicle's usability under freezing conditions. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] Figure 1 This is a schematic diagram of the structure of a car door temperature control device according to one embodiment of the present invention.

[0027] Figure 2 This is a schematic diagram of the working process of a car door temperature control device according to one embodiment of the present invention. Detailed Implementation

[0028] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0029] Please refer to Figure 1 As shown, Embodiment 1 of this utility model provides a car door temperature control device, comprising:

[0030] The interior door air outlet branch circuit is connected to the main air duct inside the vehicle;

[0031] An interior air outlet branch located inside the door and connected to the interior door air outlet branch via a flexible ventilation connection component;

[0032] An air outlet pipe is connected to the air outlet branch inside the door and is used to outlet air to the door handle area outside the door and the button area inside the door, respectively.

[0033] A door air outlet damper installed on the main air duct inside the vehicle and used to control the air outlet branch to the door inside the vehicle;

[0034] A door end damper installed on the air outlet branch inside the door and used to control the air outlet to the air outlet duct.

[0035] As can be seen from the above structure, this utility model, through innovative air duct design, extends the air outlet from the main air duct inside the vehicle to the inside of the door, realizing automatic temperature adjustment of the door handle and the button area inside the vehicle. This not only improves the user experience, but also enhances the vehicle's adaptability and energy-saving performance through intelligent temperature control.

[0036] Specifically, this utility model aims to solve the problem of poor user experience in existing car doors under extreme temperature environments, such as overheating of the exterior door handle and button area at high temperatures, and icing of the exterior door handle at low temperatures, making it impossible to open the door. The following is a detailed description.

[0037] The main air duct is installed inside the vehicle body, with one end connected to the air conditioning system's compressor, serving as the primary airflow channel for the vehicle's ventilation system. The main air duct is made of robust materials with excellent thermal insulation properties, effectively reducing heat loss during the transmission of hot and cold air and ensuring efficient temperature regulation. As an example, the main air duct has a rectangular tubular structure.

[0038] The door air vents are connected to the main air duct inside the vehicle. The door air vents can withstand a certain pressure, ensuring that the airflow can flow steadily and smoothly towards the door in different air outlet modes.

[0039] The interior air vent branch is located inside the door and connects to the interior door air vent branch via a flexible ventilation connection component. This flexible ventilation connection component provides a soft connection between the interior air vent branch and the interior air vent branch. Its internal structure ensures smooth airflow while maintaining good flexibility to accommodate the relative movement of the door during opening and closing, thus achieving air delivery to the moving door components and ensuring the reliability of the ventilation connection. As an example, the flexible ventilation connection component can be a flexible copper tube joint with an internal movable copper mesh.

[0040] The air vents from the exterior door handles and the interior door button area are connected to the interior door air vent branches, respectively, and correspond to the exterior door handle area and the interior door button area. They respectively direct airflow from the interior door air vent branches into the corresponding exterior door handle area and interior door button area. As an example, the exterior door handle air vents and the interior door button area air vents are arranged in a herringbone pattern.

[0041] It is understood that, corresponding to the left and right doors, the door air vent branches include the left door air vent branch and the right door air vent branch; the door interior air vent branches also include the left door interior air vent branch and the right door interior air vent branch; the door exterior handle air vent pipes include the left door exterior handle air vent pipes and the right door exterior handle air vent pipes; and the door interior button area air vent pipes include the left door interior button area air vent pipes and the right door interior button area air vent pipes. Since the door temperature control device in this embodiment can be independently applied to the left and right doors, the aforementioned left and right structures are identical. For simplicity, unless otherwise specified, left and right will not be distinguished below. As an example, the door air vent branches, door interior air vent branches, door exterior handle air vent pipes, and door interior button area air vent pipes are all circular tube structures.

[0042] The door vent dampers are installed on the main air duct inside the vehicle and are used to control the airflow to the left and right door vents. They are electronically controlled and can quickly and accurately adjust their opening degree according to the vehicle's temperature control commands. When closed, they effectively prevent airflow leakage, and when open, they ensure smooth airflow.

[0043] The door end damper is installed on the internal air outlet branch of the door and is located at the intersection of the air outlet duct of the external door handle and the air outlet duct of the internal button area. It uses electronic control to control the distribution of airflow inside the door. By precisely controlling the opening of the door end damper, the direction and flow of air flowing to the external door handle and the internal button area can be adjusted, thereby achieving precise temperature control of these two key areas. As mentioned earlier, the air vents from the exterior door handle and the interior door button area form a herringbone arrangement. When the door end damper is in the central position, airflow can enter the exterior door handle air vent and the interior door button area air vent from the interior door air vent branch respectively. When the door end damper closes towards the exterior door handle air vent, the exterior door handle air vent is closed, and airflow cannot enter the exterior door handle air vent, but can only enter the interior door button area air vent.

[0044] In addition, an interior air vent damper is installed on the main air duct, located slightly downstream of the duct, to control whether air is vented into the vehicle. This damper is also electronically controlled, with performance parameters meeting the requirements for precise control of airflow within the vehicle under different temperature control modes.

[0045] As mentioned above, the door temperature control device according to this utility model embodiment can provide cooling and heating capabilities to the button area inside the door and the door handle outside the door. Please refer to... Figure 2 As shown, the specific implementation process is as follows:

[0046] (I) Rapid Cooling Mode

[0047] When a user triggers a remote vehicle standby operation and the vehicle temperature exceeds a certain set high-temperature threshold (e.g., a temperature >26°C detected by the vehicle's built-in temperature sensor), the vehicle automatically activates the rapid cooling mode. In this mode:

[0048] 1. Both the left and right interior door air vents and the interior air vent dampers are open. The opening degree of the left and right interior door air vent dampers is adjusted according to the vehicle's preset airflow strategy to ensure sufficient airflow towards the doors. Cold air enters the interior door air vent branch circuit through the ductwork and flexible ventilation connection components. The opening degree of the interior air vent dampers ensures that a certain amount of cold air also reaches the interior of the vehicle.

[0049] 2. Adjust the door vents to the middle position so that cool air can flow to the air outlets of the exterior door handles and the interior door button area, cooling the exterior door handles and interior door buttons. When the user gets into the vehicle, these two main touch components can provide a suitable operating temperature.

[0050] 3. Throughout the rapid cooling process, the vehicle's temperature control system continuously monitors the temperature of the door handles and door button areas, and dynamically adjusts the opening of the relevant dampers based on the temperature feedback to achieve the best cooling effect.

[0051] (II) Quick Heating Mode

[0052] When a user triggers remote vehicle standby and the vehicle temperature is below a certain set low-temperature threshold (e.g., detected by the vehicle's built-in temperature sensor as <5°C), the vehicle automatically activates the rapid warm-up mode. In this mode:

[0053] 1. Similar to the rapid cooling mode, hot air starts from the main air duct inside the vehicle and follows the same ventilation path, that is, it enters the air outlet branch of the door through the air ducts of the left and right interior doors and the flexible ventilation connection components.

[0054] 2. Adjust the air damper at the end of the door to the middle position, allowing hot air to flow separately to the air vents on the exterior door handle and the interior door button area, heating both components. This ensures a suitable operating temperature for the user when they enter the vehicle.

[0055] 3. Throughout the rapid heating process, the opening of the relevant air dampers is adjusted based on the real-time temperature feedback from the door handles and door button areas to achieve the best heating effect.

[0056] (III) Rapid Ice Melting Mode

[0057] When a user finds ice forming on the exterior door handles in low-temperature environments, the rapid de-icing mode can be triggered. In this mode:

[0058] 1. The interior air vents are closed, the left and right interior door air vents are open, the door end vents are closed, and the air ducts in the door button area are closed.

[0059] 2. Under the action of the blower, the hot airflow throughout the vehicle passes at high speed through the main air duct, the interior door vents, flexible ventilation connections, and the interior door vents, ultimately being directed towards the exterior door handle area for rapid de-icing. During this rapid de-icing process, the vehicle's temperature control system monitors the melting of ice on the door handles. Once the ice has completely melted, it automatically switches to the normal door temperature control mode, such as selecting a rapid heating mode or maintaining a suitable ventilation state based on the current vehicle temperature.

[0060] After all the above modes have been executed, when the user enters the vehicle, the door end damper closes the air vents outside the door handle. This reduces unnecessary energy consumption and improves the vehicle's energy efficiency. Simultaneously, in this state, more airflow is directed into the vehicle to maintain a comfortable temperature environment.

[0061] It should be noted that, in this embodiment of the utility model, the vehicle temperature can be defined in the following ways:

[0062] (a) In-vehicle ambient temperature

[0063] The interior temperature of a vehicle directly affects the user's comfort when entering the vehicle. When the interior temperature is too high or too low, adjusting the temperature of the door handles and button areas can make users feel comfortable when touching these parts. Moreover, the interior temperature can be measured relatively accurately by the vehicle's own temperature sensors.

[0064] For example, after a vehicle has been parked in the sun for an extended period, the interior temperature may rise to 40°C or even higher. In this case, when a user remotely starts the vehicle, if the ambient interior temperature is used as a criterion and the system is set to activate rapid cooling when the temperature exceeds 26°C, the system will initiate cooling operations on the exterior door handles and interior door button areas. Similarly, in cold weather, if the interior temperature drops below 5°C, rapid heating will activate to ensure that users do not feel cold when touching the door components.

[0065] (ii) Temperature of door components

[0066] Door component temperature refers to the temperature measured by temperature sensors on components related to door temperature control, such as the interior door air vents and the area near the door's end damper. The temperature of these components can reflect the temperature status of the exterior door handles and interior button areas.

[0067] For example, assuming the vehicle is turned off for a period of time after operation, the temperature near the air vents inside the car doors may differ from the ambient temperature due to the vehicle's own heat dissipation characteristics. If the temperature near the air vents inside the car doors is higher than 26°C, the rapid cooling mode can be activated. Conversely, if the temperature in that area is lower than 5°C, the rapid heating mode will be activated.

[0068] (III) Comprehensive Temperature Judgment (Combining In-Vehicle Ambient Temperature and Temperature of Key Vehicle Components)

[0069] By comprehensively considering both the interior temperature and the door component temperature, a more complete and accurate determination can be made as to whether to activate the rapid cooling or rapid heating mode. Furthermore, by setting specific weights or logical judgment rules, temperature control errors caused by inaccurate measurements of a single temperature element can be avoided.

[0070] For example, when the ambient temperature inside the car is 24℃, but the temperature of the air vents in the car doors is 30℃, the system will determine that the rapid cooling mode needs to be activated based on preset rules (such as a higher weighting for the temperature of the air vents in the car doors). Or, in cold weather, if the ambient temperature inside the car is 7℃, but the temperature of the air vents in the car doors is 3℃, the rapid heating mode will be activated after comprehensive judgment to ensure that the temperature of the door handles and the button areas inside the car is suitable.

[0071] Corresponding to the door temperature control device described in Embodiment 1 of this utility model, Embodiment 2 of this utility model also provides a vehicle including the aforementioned door temperature control device.

[0072] For the working principle and process of the above embodiments, please refer to the description of Embodiment 1 of this utility model, which will not be repeated here.

[0073] As described above, compared with existing technologies, the advantages of this invention are as follows: it significantly improves the functionality of the car door under extreme weather conditions and enhances user comfort. Through an integrated door ventilation system and intelligent temperature control mechanism, it can precisely regulate the temperature of the door handles and button areas. In high-temperature environments, the rapid cooling mode automatically adjusts the air damper to effectively reduce the temperature of the door handles and button areas, preventing users from experiencing discomfort due to overheating. In low-temperature environments, the rapid heating mode delivers hot air to prevent the door handles from freezing, ensuring smooth door operation. Furthermore, this invention automatically closes the air ducts of the door handles after the user enters the vehicle, reducing unnecessary energy consumption. The introduction of a rapid de-icing mode, using high-speed hot airflow to quickly melt ice, further improves the vehicle's usability under freezing conditions.

[0074] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
