Description

Technical Field

[0001] The utility model belongs to the technical field of electric forklifts, and in particular relates to a temperature regulating control system used in an electric forklift complete machine, and also comprises an electric forklift comprising the temperature regulating control system. Background Art

[0002] The electric forklift consists of multiple systems and structures, such as the cab, power system, hydraulic system, etc. Therefore, the machine is equipped with multiple temperature control systems for different systems, such as the cab air conditioning system, power battery water cooling system, etc. The temperature control systems of these two systems keep the corresponding systems within a reasonable temperature range, thereby ensuring reliable and efficient operation of the whole machine.

[0003] However, since the cab air conditioning system and the power battery water cooling system are two independent systems, their system layout is relatively complex, and the independent system costs are higher. More importantly, there is a waste of heat source when two independent temperature control systems work at the same time. For example, in winter, when the whole machine works for a long time, the heat dissipated by the battery due to the high temperature is usually directly discharged into the atmosphere, which does not save energy, consumes excess electricity, and causes a waste of heat source. Utility Model Content

[0004] In view of this, it is necessary for the utility model to provide a temperature control system, which is a single-source multi-zone temperature control system, which controls the temperature of the battery module and the cab respectively through independent air-conditioning units, and under certain working conditions, the heat dissipated from the battery module can be introduced into the cab to provide thermal energy for heating the cab, thereby reducing energy consumption.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The first aspect of the utility model provides a temperature adjustment control system, comprising:

[0007] A cab, wherein a first temperature sensor for measuring the temperature of the cab is disposed in the cab;

[0008] a battery module, wherein the battery module is connected to a second temperature sensor for measuring the temperature of the battery module;

[0009] an air conditioning unit, for regulating the temperature of the battery module and the cab, and obtaining power supply from the battery module;

[0010] and a controller for receiving temperature data from the first temperature sensor and the second temperature sensor and controlling the air conditioning unit;

[0011] Wherein, the battery module includes a heating mode and a heat dissipation mode. When it is in the heat dissipation mode, the heat generated by it can be sent into the cab, so that the cab enters a heating state.

[0012] In a further aspect, the temperature adjustment control system further comprises a power supply unit, and the power supply unit is used to supply power to the controller.

[0013] In some specific implementations, the power supply unit is a low-voltage battery.

[0014] In a further solution, the battery module is also connected to a battery management system.

[0015] In a further solution, the battery module is a lithium battery module, the battery management system is a BMS, and the BMS obtains power through the power supply unit for managing and monitoring the lithium battery module.

[0016] In a further solution, a control panel is provided in the cab, and the control panel obtains power through the power supply unit and can be used to control the temperature state in the cab.

[0017] In a further embodiment, the air conditioning unit is an independent high-pressure air conditioning unit.

[0018] In a further solution, the controller is connected to a valve and a fan for controlling the flow of heat source water. When the battery module is in a heat dissipation mode, the controller can control the valve and the fan to send the heat generated by the battery module in the heat dissipation mode into the cab through a pipeline.

[0019] A second aspect of the utility model provides an electric forklift, comprising the temperature adjustment control system as described above.

[0020] Beneficial effects of the utility model:

[0021] The temperature adjustment control system in the utility model adopts independent air conditioning units to control the temperature of the cab and the battery module, so the control is more centralized and the cost is lower.

[0029] This embodiment provides a temperature control system, and its connection and principle are as follows: Figure 1 As shown in , the temperature control system includes a cab 100, a lithium battery module 200, an air conditioning unit 300, a controller 400 and a power supply unit 500, wherein the controller 400 is connected to the air conditioning unit 300 to control the opening or closing of the air conditioning unit 300.

[0030] Among them, the cab 100 is connected with a control panel 110 and a first temperature sensor 120. The control panel 110 is used for the driver to operate the control system. In this embodiment, the temperature state in the cab 100 is mainly controlled as needed, including a heating state and a cooling state. Specifically, the control panel 110 is connected to the controller 400, and the air conditioning unit 300 is controlled to be turned on by the controller 400. The first temperature sensor 120 is used to measure the temperature in the cab 100, and the first temperature sensor 100 is connected to the controller 400, and the temperature data in the cab 100 can be fed back to the controller 400.

[0031] The lithium battery module 200 is connected to the BMS 210 and the second temperature sensor 220, wherein the BMS 210 is used to monitor and manage the lithium battery module 200. The second temperature sensor 220 is used to measure the temperature of the lithium battery module 200, and the second temperature sensor 220 is connected to the controller 400, and the temperature data of the lithium battery module 200 can be fed back to the controller 400. The lithium battery module 200 also includes a valve and a fan for controlling the flow of heat source water, and the valve and the fan are respectively connected to the controller 400.

[0032] In this embodiment, the air conditioning unit 300 is an independent high-voltage air conditioner, which is connected to the lithium battery module 200 and the cab 100 respectively to adjust the temperature of the lithium battery module 200 and the cab 100. At the same time, the air conditioning unit 300 obtains power from the lithium battery module 200.

[0033] Furthermore, the power supply unit 500 is mainly used to supply power to the electrical components in the system. Specifically, the power supply unit 500 is connected to the control panel 110, the BMS 210 and the controller 400 respectively to supply power to the above electrical components. In this embodiment, the power supply unit 500 is a low-voltage battery, but is not limited thereto.

[0034] The working principle of the temperature control system in this embodiment is as follows:

[0035] When the whole machine is working, the control panel 110, BMS210 and controller 400 work under the power supply of the power supply unit 500, and the opening value of the air-conditioning unit 300 is preset in the controller 400. The controller 400 determines whether to turn on the air-conditioning unit 300 according to the temperature feedback of the first temperature sensor 120 and the second temperature sensor 220. Specifically, the first temperature sensor 120 and the second temperature sensor 220 feed back the temperature of the cab 100 and the lithium battery module 200 to the controller 400 in real time. The controller 400 determines whether to turn on the air-conditioning unit 300 according to the preset opening value and real-time temperature feedback, thereby performing real-time temperature adjustment on the two modes of heating mode and heat dissipation mode of the lithium battery module 200; and the two modes of heating state and cooling state of the cab 100 are adjusted in real time by the control panel 110.

[0036] When the whole machine is operating under winter conditions, the second temperature sensor 220 feeds back the real-time temperature to the controller 400, and the controller 400 controls the air conditioning unit 300 to turn on, so that the lithium battery module 200 is in the heat dissipation mode. At the same time, when the cab 100 needs to be heated, the first temperature sensor 120 feeds back the temperature of the cab 100 to the controller 400, and the controller 400 controls the valve and fan of the heat source water flow to turn on, and the fan sends the heat generated by the heat dissipation mode of the lithium battery module 200 into the cab 100 through the pipeline, so that the cab 100 is in the heating state, thereby avoiding the consumption of heat energy converted from the electric energy of the lithium battery module 200 through the heating mode of the air conditioning unit 300, which can well reduce energy consumption.

[0037] In general, the temperature adjustment control system provided in this embodiment has the advantages of simpler system layout, more convenient subsequent maintenance, and lower energy consumption.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
