[0002] During the use of the truck, the truck's starting battery is crucial for the normal starting and operation of the truck. The current truck's starting battery has the following problems:

[0003] (1) The SOC (State of Charge) of the starter battery of an existing truck requires changing the shape of the battery box according to the appearance of the display light or display screen, which is complicated to operate, has low installation efficiency, and has a high cost for changing the box shape.

[0004] (2) Common functions of starting batteries include SOC display function, forced start function (to prevent the vehicle from breaking down due to battery problems) and Bluetooth function, but existing truck starting batteries do not integrate the above three functions into one.

[0005] (3) Regarding the Bluetooth function, the conventional practice is to integrate a Bluetooth module on the BMS board in the battery box so that it can be connected to the user's mobile phone or vehicle terminal via Bluetooth to obtain detailed status information of the starting battery in real time, such as battery voltage, power, battery health, charge and discharge times, etc. At the same time, the Bluetooth function can also be used to remotely monitor and manage the starting battery. However, for safety reasons, general battery boxes use iron box technology, which causes the Bluetooth signal in the battery box to be shielded and interfered by the battery box body, resulting in the inability to efficiently transmit the Bluetooth signal, which will cause problems such as freezing and disconnection.

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the present application in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0029] Embodiment 1

[0030] See also Figures 1 to 7 The present application discloses an integrated device 100 for a starting battery of a truck. The starting battery includes a BMS board 200, and the starting battery is disposed in a battery box 300. The integrated device 100 includes a housing 1 and a SOC display module 11, a forced starting switch module 12, and a Bluetooth module 13 disposed in the housing 1, and the integrated device 100 is configured to be assembled on the battery box 300.

[0031] The SOC display module 11 is configured to be connected to the BMS board 200 , and to receive and display the SOC of the starting battery output by the BMS board 200 .

[0032] The forced start switch module 12 is configured to be connected to the BMS board 200, and is used to start the forced start circuit of the BMS board 200 for forced start. Specifically, when the short-term high current required to start the truck is not met, or when the starting battery power is lower than the normal starting threshold but there is still a certain amount of remaining power, the forced start circuit of the BMS board 200 can be started by the forced start switch module 12 to temporarily increase the output voltage and current to achieve forced start of the truck. It should be noted that the number of forced starts should be limited to avoid excessive loss of starting battery life.

[0033] The Bluetooth module 13 is configured to be connected to the BMS board 200. Specifically, the Bluetooth module 13 can be connected to the user terminal in communication, and the user terminal can receive the status information of the starting battery output by the BMS board 200 through the Bluetooth module 13, and can also monitor and manage the starting battery through the Bluetooth module 13. More specifically, the status information of the starting battery includes but is not limited to the battery voltage, power, charge and discharge current, battery health, charge and discharge times, battery real-time temperature, historical power data, etc. In addition, when the starting battery has an abnormal condition, such as over-discharge or high temperature, an alarm message can also be sent to the user terminal through the Bluetooth module 13.

[0034] In some embodiments, the housing 1 is provided with a threaded portion 10, which is configured to be threadedly connected to a threaded hole (not shown) on the battery box 300. By opening a threaded hole on the battery box 300, and then threading the threaded portion 10 of the housing 1 to the threaded hole on the battery box 300, the integrated device 100 can be stably assembled on the battery box 300, without changing the shape of the battery box 300 according to the shape of the SOC display light or the display screen, eliminating the complicated battery box 300 mold opening process, and the operation is simple, the installation efficiency is high, and it can adapt to battery boxes 300 of different shapes. Of course, the integrated device 100 can also be assembled on the battery box 300 in other ways, such as using glue to assemble the integrated device 100 and bond it to the battery box 300 after drilling holes through the battery box 300.

[0035] Specifically, the main body diameter of the housing 1 is about 20 mm.

[0036] Specifically, the end of the housing 1 away from the battery box 300 is set to a nut type. By setting the end of the housing 11 away from the battery box 300 to a nut type, it is convenient to rotate the end of the nut type to thread the threaded portion 10 of the housing 1 and the threaded hole of the battery box 300. Of course, it is not limited to this.

[0037] In some embodiments, a circuit board 14 is provided in the housing 1, the SOC display module 11 includes a SOC display circuit 110, the forced start switch module 12 includes a forced start switch circuit 120, and the Bluetooth module 13 includes a Bluetooth circuit 130. The SOC display circuit 110, the forced start switch circuit 120, and the Bluetooth circuit 130 are integrated on the circuit board 14 and connected to the BMS board 200. It should be noted that it is not excluded that there are common parts (such as a shared processor) between the SOC display circuit 110, the forced start switch circuit 120, and the Bluetooth circuit 130, which is not limited here. By integrating the circuits of the three modules on the circuit board 14 and then connecting them to the BMS board 200, the integration is high and materials are saved, but it is not limited to this. For example, the SOC display circuit 110, the forced start switch circuit 120, and the Bluetooth circuit 130 can also be set on different circuit boards 14.

[0038] The Bluetooth module 13 also includes a Bluetooth antenna (not shown), which can be connected to the Bluetooth circuit 130 via a feeder. The present application does not limit the form of the Bluetooth antenna, and the Bluetooth antenna can be disposed on the circuit board 14, such as being directly printed on the circuit board 14.

[0039] Specifically, the circuit board 14 is connected with a connection line 4, and the SOC display circuit 110, the forced start switch circuit 120, and the Bluetooth circuit 130 are configured to be connected to the BMS board 200 through the connection line 4. More specifically, a connector 141 is provided at the bottom of the circuit board 14, one end of the connection line 4 is connected to the connector 141, and the other end is connected to the connector 21 of the BMS board 200 to connect the circuit board 14 to the BMS board 200. The connection line 4 can be a flexible flat cable, etc.

[0040] More specifically, a soft plug structure 15 is provided at the bottom of the housing 1, and the soft plug structure 15 is used to position the connecting wire 4. In some embodiments, the SOC display module 11 includes a SOC display circuit 110, and the SOC display circuit 110 includes a SOC display light 111. The SOC display light 111 is configured to display the SOC of the starter battery output by the BMS board 200. Of course, the SOC display circuit 110 may also include an exposed SOC display screen to display the SOC, which is not limited here.

[0041] Specifically, the SOC display light 111 is a plurality of LED lights, and different SOCs (power status display) are indicated by different colors of the LED lights. Exemplarily, a green light indicates 100% power, an orange light indicates 75% power, a yellow light indicates 50% power, and a red light indicates 25% power, but this is not limited thereto. In addition, the SOC display light 111 can also be set to a plurality of LED lights in a segmented manner to indicate the SOC, such as 1 LED light represents 25% power, 2 LED lights represent 50% power, 3 LED lights represent 75% power, and 4 LED lights represent 100% power. The number of SOC display lights 111, display logic, and colors corresponding to power levels, etc. can be in other forms and are not limited here.

[0042] Specifically, the SOC display circuit 110 is disposed on the circuit board 14. It should be noted that the SOC display circuit 110 is disposed on the circuit board 14, which is not limited to the SOC display circuit 110 being completely disposed on the circuit board 14. For example, the SOC display light 111 may not be disposed on the circuit board 14, but may be connected to the circuit on the circuit board 14 via a wire.

[0043] In some embodiments, the forced start switch module 12 includes a forced start switch circuit 120, and the forced start switch circuit 120 includes a forced start state display light 121. Since forced start takes some time, the forced start state display light 121 is turned on when in the forced start state, so that the user can visually observe that the truck is in the forced start state, and avoid the user from performing operations that may damage the truck or cause safety hazards when the truck is in the forced start state.

[0044] Specifically, the forced start switch circuit 120 is disposed on the circuit board 14. It should be noted that the forced start switch circuit 120 is disposed on the circuit board 14, which is not limited to the forced start switch circuit 120 being completely disposed on the circuit board 14. For example, the forced start state display light 121 may not be disposed on the circuit board 14, but may be connected to the circuit on the circuit board 14 through a wire.

[0045] Specifically, the display logic of the SOC display light 111 and the forced start state display light 121 may be controlled by the circuit board 14 , but is not limited thereto.

[0046] Specifically, the integrated device 100 further includes a light guide 2, which is disposed in the housing 1 and exposed to the outside, and is used to conduct the internal light to the outside. It should be explained that the light guide 2 is made of a transparent or translucent optical material, and when the SOC display light 111 and the forced start status display light 121 are turned on, the light can be transmitted to the outside of the integrated device 100 through the light guide 2, so that the user can visually observe the light of the SOC display light 111 and the forced start status display light 121 through the light guide 2 outside the battery box 300.

[0047] More specifically, the light guide 2 is ring-shaped and exposed on the upper side of the housing 1 .

[0048] In some embodiments, a circuit board 14 is provided in the housing 1, and the forced start switch module 12 includes a forced start switch circuit 120 and a forced start switch 122 provided on the circuit board 14 to press a panel 123, the forced start switch circuit 120 includes a forced start state display light 121, the forced start switch 122 is provided on the circuit board 14 and connected to the forced start switch circuit 120, the pressing panel 123 is located above the forced start switch 122, the upper side of the pressing panel 123 is exposed to the outside, and an upwardly exposed annular light guide 2 is provided between the pressing panel 123 and the side wall of the housing 1. Specifically, the user presses the pressing panel 123 and then presses the forced start switch 122, so that the forced start switch circuit 120 connected to the forced start switch 122 sends a forced start signal to the forced start circuit of the start BMS board 200 to perform forced start.

[0049] Specifically, a sealing ring 3 is provided between the pressing panel 123 and the light guide 2 to provide better waterproof performance.

[0050] Specifically, the housing 1 is made of metal, and the light guide 2 serves as a transmission medium for the Bluetooth signal received and sent by the Bluetooth module.

[0051] In some embodiments, the integrated device 100 is packaged using a glue injection process. After the integrated device 100 is assembled, the glue injection process is used to package the integrated device 100, which can make the integrated device 100 more waterproof and vibration-proof, but is not limited thereto.

[0052] In the embodiment of the present application, the integrated device 100 includes a housing 1 and an SOC display module 11, a forced start switch module 12 and a Bluetooth module 13 arranged on the housing 1, and the integrated device 100 is assembled on the battery box 300. The embodiment of the present application does not need to change the shape of the battery box according to the appearance of the SOC display light or the display screen, which improves the assembly efficiency. Moreover, the three functions are integrated to form an independent integrated device 100, which can be installed on different types of battery boxes 300, thereby improving the user experience. In addition, the integrated device 100 is assembled on the battery box 300, and the signal of the Bluetooth module 13 will not be shielded and interfered by the battery box 300 (generally using an iron box process), which improves the transmission efficiency of the Bluetooth signal and is conducive to improving problems such as freezing and disconnection.
