Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle accessories and relates to an expansion kettle. Background Art

[0002] In order to solve the range anxiety problem of pure electric vehicles, hybrid vehicles came into being and occupied a large market share in a short period of time. Although hybrid vehicles can effectively solve the range anxiety problem, the front cabin of hybrid vehicles is equipped with both electric motors and engines, resulting in a very compact layout of various components in the front cabin. In order to alleviate the space in the front cabin, many car companies integrate the electric drive kettle and the battery circuit kettle together to form an integrated kettle. Using an integrated kettle instead of a battery kettle and an electric drive kettle can save some space in the front cabin.

[0003] When the integrated kettle is arranged in the front cabin, there is a problem that the liquid level in the kettle is not easy to observe. In order to solve the problem of difficulty in observing the liquid level in the integrated kettle, the existing solution is to add a liquid level sensor. Usually, a liquid level sensor is arranged in a kettle. For the integrated kettle, two liquid level sensors need to be arranged at the same time, and the distance between the two liquid level sensors is relatively close, which appears messy after the wiring harness is connected. At the same time, arranging two liquid level sensors in the integrated kettle will increase the cost of the integrated kettle.

[0004] In order to solve the above problems, an expansion kettle is needed, which can effectively solve the problem of disordered wiring harnesses in the front cabin and reduce costs and improve economic benefits while conveniently monitoring the liquid level in the kettle. Utility Model Content

[0029] In this embodiment, a single sensor 9 type integrated expansion kettle includes:

[0030] The kettle body is a hollow cavity structure; a partition 12 is provided in the kettle body, and the partition 12 separates the cavity of the kettle body into a battery cooling liquid cavity 10 and an electric drive cooling liquid cavity 11; the battery cooling liquid cavity 10 is used to hold the cooling medium of the battery cooling system, and the electric drive cooling liquid cavity 11 is used to hold the cooling medium of the electric drive cooling system

[0031] The monitoring component includes a sensor 9 and a monitoring split body that cooperates with the sensor 9. There are two monitoring split bodies, and the two monitoring split bodies are respectively and correspondingly arranged in the battery cooling liquid cavity 10 and the electric drive cooling liquid cavity 11. The sensor 9 monitors the liquid level of the coolant in the battery cooling liquid cavity 10 and the electric drive cooling liquid cavity 11 through the monitoring split body. By using a solution of one sensor 9 and two monitoring split bodies and setting a monitoring split body in each cavity, the liquid level in the two cavities can be monitored synchronously by one sensor 9, which reduces the production cost and the number of wiring harnesses, and can effectively solve the problem of disordered connection wiring harness of the integrated kettle liquid level sensor 9. In actual use, although the battery and the electric drive can be cooled using the same cooling medium, since the battery cooling system and the electric drive cooling system belong to two independent circuits and the two systems have different requirements for cooling, it is necessary to separate and store their respective cooling media to ensure the normal operation of the two systems. Since it is the same cooling medium, a sensor 9 can be used in conjunction with two monitoring splits to synchronously monitor the liquid levels in the two cavities. During actual driving, no matter which cavity the liquid level is below the warning value, an alarm will be triggered. At the same time, no matter which cavity triggers the alarm, it is necessary to stop and check for safety reasons. Therefore, when monitoring the liquid level, for cost control reasons, only one sensor 9 can be used.

[0032] In this embodiment, the sensor 9 is a reed switch liquid level sensor 9, the monitoring split body is a magnetic float, a compartment 13 is provided in the compartment 12, the reed switch liquid level sensor 9 is provided in the compartment 13, the two magnetic floats are respectively provided in the battery coolant chamber 10 and the electric drive coolant chamber 11, and the two magnetic floats are respectively provided in correspondence with the wall surface of the compartment 12 in a single degree of freedom sliding manner that can be limited. In this embodiment, a reed switch liquid level sensor 9 is used in conjunction with a magnetic float to monitor the liquid level. When the magnetic float in the cavity changes with the liquid level, the reed switch located in the compartment 13 is connected in sequence, causing the resistance value of the liquid level sensor 9 to change. The resistance value is converted into a current signal output through the circuit module, and the liquid level in the kettle body is monitored through the connection relationship between the magnetic steel in the float and the reed switch. The reed switch liquid level sensor 9 can monitor the liquid level information in two kettle bodies at the same time, reducing the cost of the second liquid level sensor 9 and only requiring a single wiring harness to be connected. This solution can effectively solve the problem of disordered wiring harnesses in the front cabin. At the same time, the monitoring method of the sensor 9 is wireless, so the number of wiring harnesses between the sensor 9 and the monitoring split can also be reduced, and no direct contact is required, which effectively improves the sealing of the kettle body.

[0033] In this embodiment, a partition I 14 and a partition II 15 are provided in the kettle body, and the partition I 14 and the partition II 15 are arranged along the lateral direction of the kettle so that the cavity of the kettle body is divided into a battery cooling liquid cavity 10, a partition 12 and an electric drive cooling liquid cavity 11. The double partition design can further improve the sealing performance of the kettle body, effectively separate the two cavities, and facilitate the formation of the partition 12 and the arrangement of the partition cavity 13.

[0034] In the present embodiment, the kettle body is composed of an upper kettle body 1 and a lower kettle body 2 which are buckled together, and the upper kettle body 1 and the lower kettle body 2 are connected by hot plate welding. The compartment 13 is formed by an upward depression on the bottom surface of the lower kettle body 2, and the sensor 9 is installed in the compartment 13 by plugging. In the present embodiment, the upper and lower kettle bodies 2 are formed by hot plate welding, which has better integrity and better sealing effect. In the present embodiment, the installation and placement of the two partitions in the kettle can be plug-in, or can be integrally formed with the kettle body. The installation of the partitions is the application of conventional technical means of technicians in this technical field, so it is not repeated here.

Through the sliding cooperation of the guide rail and the slide groove, the limited single-degree-of-freedom sliding of the magnetic float 16 is achieved. In this embodiment, the magnetic float 16 floats up and down with the liquid level under the buoyancy of the coolant, and the two guide rails limit it to ensure that the sensor 9 can always be connected with the magnetic float 16 to ensure normal monitoring.
