Description

Technical Field

[0001] The utility model relates to the technical field of automobile equipment, in particular to a preheating automobile heater. Background Art

[0002] In the cold winter, once a car is parked outdoors for more than a certain period of time, especially after being parked overnight, when the driver and passengers just get in the car, the temperature inside the car is often very low, even in the south it is only a few degrees Celsius, not to mention the cold north where it is minus ten or even dozens of degrees, which makes people feel extremely uncomfortable. In order to increase the comfort of driving, people often need to wait for the car's built-in warm air conditioning system to heat the temperature inside the car to a comfortable level, which takes 10 minutes or even longer. On the other hand, when the car is parked outdoors in rainy and snowy weather, the car windows will also freeze or fog up. In order to remove the ice or fog on the car windows, it is also necessary to start the air conditioner for a long time to defrost or defog after the cold car is started.

[0003] In order to solve the above problems, there have been some attempts in the prior art. For example: Chinese patent document CN113954600A discloses a vehicle parking ice warning preheating method, device, equipment and storage medium, but the technology is only applicable to new energy vehicles with large-capacity batteries, and can generally only be used when new cars are manufactured, and is not applicable to car modification. For fuel vehicles, since the capacity of the on-board battery is too small, the air conditioner is generally not directly turned on by taking power from the battery. Chinese patent document CN115465049A discloses a parking warm air control method, system, vehicle and medium. The technology uses an independent fuel heater to provide heating in the car when the car is parked (the car engine is not working). However, since the system needs to set up an independent fuel heater, the entire warm air system is large in size, and when used for the modification of existing cars, the car oil circuit needs to be changed, which is not only inconvenient but also brings hidden dangers of use. Therefore, the fuel vehicles with a large number of vehicles on the market and the new energy vehicles without parking heating function need an economical and convenient car preheating device that can be installed later.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] This specific implementation provides a preheating automobile heater, which solves the technical problem that the automobile in the prior art does not have a parking heating function.

[0027] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0028] Reference Figure 1-Figure 3 The utility model provides a preheating automobile heater, comprising:

[0029] The electrical equipment is provided with at least one electrical equipment which can be installed at any position in the vehicle interior space to provide warm air for the vehicle interior, wherein the electrical equipment includes a first shell 1, a heating device 2, and a fan 3, wherein the first shell 1 is provided with an air inlet 6, an air outlet 7, and a channel connected to the air inlet 6 and the air outlet 7, and the fan 3 and the heating device 2 are provided between the air inlet 6 and the air outlet 7, and the fan 3 blows the hot air heated by the heating device 2 to the air outlet 7. Due to the principle of air circulation, when the gas flows out of the first shell 1, the gas must enter the first shell 1 through the air inlet 6, and such a cycle can continuously replace the cold air in the vehicle interior, thereby heating the air in the vehicle interior.

[0030] A power supply device, which is electrically connected to the electrical equipment and provides electrical energy to the electrical equipment, wherein the power supply device includes a second shell, a battery pack 5, and a second control device, wherein the second control device controls the opening and closing of the power supply device, and the second control device is provided with a timing circuit, so that the second control device stops supplying power to the electrical equipment when a predetermined time is reached; wherein the second control device is provided with a timing circuit, so that the second control device turns on and off the power supply device when a predetermined time is reached, so that people directly start the timing circuit after leaving the car, and when the predetermined time is reached, the second control device controls the power supply device to turn on, and then turns on the fan 3 and the heating device 2, so that when people use the car, the air in the car is warm. At the same time, when the car is parked outdoors in rainy or snowy weather, ice or fog will form on the car windows. In order to remove the ice or fog on the car windows, it is also necessary to spend a long time to start the air conditioner to defrost or defog after the cold car is started. The use of a preheating car heater greatly saves the preheating time and ensures people's travel safety.

[0031] In this embodiment, in order to facilitate people to remotely control the operation of the preheating car heater, based on the current popularity of smart phones, a communication module is provided on the second control device, and the communication module is used to remotely connect with the mobile terminal or the vehicle-mounted host, so that the power supply device supplies power to the electrical equipment. In the event of an emergency, people can directly use the mobile terminal or the vehicle-mounted host to remotely control the opening and closing of the preheating car heater, so as to heat the car body in advance and ensure that the air in the car is warm when people get on the car. The mode of connecting the communication module to the mobile terminal is more convenient for temporary use of the car. It is only necessary to remotely start the heater a certain time in advance before using the car, and it can also be set to start the daily scheduled start or delayed start. The communication module is generally a wireless communication module, such as a Bluetooth module or a WiFi communication module. If necessary, a SIM card slot can also be set separately to connect to other mobile terminals through the operator's data network.

[0032] In this embodiment, in order to save the space occupied by the preheating car heater, the first shell 1 is set to be flat, which can reduce the height space occupied by the car body and make it convenient for people to place the preheating car heater. In order to blow hot air into the car body, the air outlet 7 is inclined to one side of the car body. Preferably, the preheating car heater is installed under the seat of the car body. Since there is a certain space under the seat of the car, in order to avoid occupying other space of the car body, the air outlet 7 is inclined to the car body so that hot air can be blown directly into the car.

[0033] In this embodiment, in order to facilitate the air inlet 6 to be set on the end face of the first shell 1 and close to the fan 3 to reduce the air inlet resistance, the air outlet 7 is set at one end of the first shell 1, wherein a grille is provided at the position of the air inlet 6, so as to prevent large foreign objects from entering the interior of the preheating car heater.

[0034] In this embodiment, the battery pack 5 is a single battery or a packaged battery pack, wherein the material of the battery pack 5 is a lithium battery or a blade battery. The "blade battery" can skip the "module" when grouping through structural innovation, greatly improving the volume utilization rate, and ultimately achieving the design goal of fitting more cells in the same space. Compared with traditional battery packs, the volume utilization rate of the "blade battery" has increased by more than 50%, which means that the cruising range can be increased by more than 50%, reaching the same level as high-energy-density ternary lithium batteries.

[0035] In this embodiment, the battery pack 5 is a rechargeable battery, and a charging port 8 is provided on the second shell, so that it is convenient to charge the battery pack 5. The battery pack 5 can be provided with multiple interfaces, which is convenient for connecting with multiple electrical devices. When 4 series and 4 parallel power batteries are used, it can work for at least 10 minutes, and when 4 series and 8 parallel power batteries are used, it can work for more than 20 minutes. And the heating device 2 can be a ceramic heating body or a heating wire, the power of the ceramic heating body or the heating wire is 500W, the fan 3 is 10W, and the total power of the heater is slightly greater than 510W. By reasonably setting the battery capacity and the power of the heating wire or the ceramic heating body, the small size and preheating capacity of the heater can be taken into account. Compared with the fuel preheating heater, the size and weight are significantly reduced, the space in the car is saved, and it can be easily installed on existing cars that do not have the parking heating function.

[0036] Among them, the core of the second control device adopts the GD32F103CBT6 chip, and the 6A lithium battery charging management circuit composed of BQ25703A (U5) is connected to the 12V to 71V charging interface at one end, and connected to the 12V to 71V-30AH-180AH lithium battery pack 5 at the other end. The second control device is provided with a charging management circuit, which detects the voltage and current of the battery pack 5 to determine whether the battery pack 5 needs to be charged. The battery pack 5 supplies power to the heating wire and the fan 3, and the opening and closing of the fan 3 and the heating wire are controlled by the second control device. The second control device is also connected to a Bluetooth module and an LED light for external communication and displaying the working status of the heater.

[0037] Among them, the battery pack 5 can be a 18650 lithium power battery with a 4-in-1 and 4-in-1 structure. The voltage of each power battery is 3.7V, and the rated voltage is 14.8V after 4 batteries are connected in series, and the working voltage is 12-14V; the power battery capacity is generally 2500mAh, and the capacity reaches 10Ah after 4 batteries are connected in parallel. According to the size of the car, the number of power batteries can be further increased to increase the total battery capacity to improve the preheating effect of the heater, but the increase in the external dimensions of the heater after adding batteries must also be considered. When 32 power batteries with 4 in series and 8 in parallel are used, the total battery capacity reaches 20Ah, and the heating capacity can be doubled.

[0038] In addition, in an emergency, the charging port 8 can be connected to the car's onboard battery or battery through a power cord. By connecting the car's onboard battery or battery, the battery life is improved. For example, for the 4-series, 4-parallel, 16-cell power battery version that can only work for 10 minutes, when the battery in the heater is consumed too much, the second control device can switch the power supply to the car battery, so that the car charges the battery pack 5, 9. Taking into account the depreciation of the onboard battery of the fuel vehicle and to ensure that the vehicle can start smoothly, it is recommended that users use the onboard battery of the fuel vehicle for no more than 10 minutes. The preheating car heater itself is powered for 10 minutes, and the overall preheating is 20 minutes. After the overall preheating, the temperature inside the car can be significantly improved even in an environment of minus 20 degrees. For ambient temperatures around zero degrees, a general preheating car heater can significantly improve the temperature inside the car by powering itself for 10 minutes.

[0039] In this embodiment, the electrical equipment also includes a first control device 4, which is electrically connected to the heating device 2 and the fan 3 to control the heating device 2 and the fan 3 to turn on and off, thereby conveniently controlling the heating device 2 and the fan 3 to turn on and off.

[0040] In this embodiment, in order to prevent the heating device 2 from overheating, a temperature detection device is provided in the first shell 1, and the temperature detection device is electrically connected to the second control device. The data detected by the temperature detection device is transmitted to the second control device, wherein the second control device is provided with a first preset value. When the temperature reaches the first preset value on the second control device, the second control device controls the heating device 2 to stop heating.
