Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: like Figures 1-3 As shown, one embodiment of the present invention provides a battery module, including a battery body 1, a lighting component 2, and a switch 3; The battery body 1 is provided with a lighting component 2 for lighting; The battery body 1 is used to power the lighting component 2, and the switch 3 is connected between the battery body 1 and the lighting component 2 to control the lighting component 2 to turn on or off.

[0022] When the main body of the electric vehicle malfunctions and the battery module cannot supply power to the main body, the battery module can be removed. The user can place the battery module in the basket and manually turn on switch 3 to enable the lighting component 2 to provide illumination instead of the headlights. This allows the user to see the road clearly when pushing the electric vehicle in dark places, making it less likely to trip over obstacles and thus safer.

[0023] A handle 12 is connected to the battery body 1, which makes it easy to remove the battery body 1 from the battery module placement area of ​​the electric vehicle.

[0024] According to one embodiment of the present invention, a heat insulation component 4 is provided at the bottom of the battery body 1, and the heat insulation component 4 is disposed between the lighting component 2 and the battery body 1.

[0025] Since the lighting component 2 generates heat when it emits light continuously, a heat insulation component 4 is added between the lighting component 2 and the battery body 1 to prevent heat transfer from damaging the battery body 1, thus providing heat insulation protection. Preferably, the heat insulation component 4 is made of aerogel felt, ceramic fiber board, or mica sheet, with a thickness of 1mm-5mm and a thermal conductivity ≤0.05 W / (m·K).

[0026] According to one embodiment of the present invention, the lighting component 2 includes an LED lamp 21.

[0027] Preferably, the LED light 21 uses multiple high-lumen SMD LED beads, and can select between constant light, flashing or SOS mode by pressing the switch 3 times. This is existing technology and will not be described in detail.

[0028] Furthermore, the LED lamp 21 includes a light-transmitting cover that is waterproof and dustproof, protecting the LED lamp 21 body and improving the lifespan of the LED lamp 21.

[0029] According to one embodiment of the present invention, the lighting component 2 further includes a base plate 22, on which a receiving groove 23 is provided. An LED light 21 is provided in the receiving groove 23. The LED light 21 is placed in the receiving groove 23 and does not protrude from the receiving groove 23. When the battery module is normally placed in the placement area under the electric vehicle seat, the bottom wall of the placement area contacts the base plate 22. Since the LED light 21 does not contact the bottom wall of the placement area, it is not easily damaged.

[0030] According to one embodiment of the present invention, the lighting assembly 2 further includes a retaining structure for retaining the LED lamp 21 within the receiving groove 23.

[0031] Preferably, the retaining structure includes a magnetic sheet 25 and a magnet 26; The magnetic sheet 25 is connected to the bottom wall of the receiving groove 23, and the magnet 26 is connected to the LED light 21. After the LED light 21 is placed into the receiving groove 23, the magnetic sheet 25 and the magnet 26 attract each other tightly, thereby fixing the LED light 21 in the receiving groove 23.

[0032] According to one embodiment of the present invention, a notch 24 is provided on the side wall of the LED lamp 21, that is, the light-transmitting cover of the LED lamp 21 is designed as... Figure 3 As shown. When it is necessary to remove the LED light 21, the LED light 21 can be removed from the receiving slot 23 by inserting a finger into the two notches 24.

[0033] Preferably, both the magnetic sheet 25 and the magnet 26 are ring-shaped, or they can be strip-shaped, etc.

[0034] Of course, in this embodiment, the fixing structure can also be in other forms. For example, the fixing structure includes a relief groove and a rotating plate. The relief groove and the receiving groove 23 are connected. A bolt is fixed in the relief groove. A strip plate is screwed onto the bolt. The strip plate does not protrude from the bottom plate 22. The strip plate can be rotated around the axis of the bolt so that the projected part of the strip plate falls into the receiving groove 23. At this time, the LED light can be restricted from detaching from the receiving groove 23. Furthermore, in order to prevent the LED light 21 from shaking in the receiving groove 23, a rubber pad can be provided on the side of the strip plate near the bottom wall of the receiving groove 23. When the strip plate restricts the LED light 21, the rubber pad contacts the LED light 21 and deforms so that the LED light 21 can be better fixed in the receiving groove 23.

[0035] According to one embodiment of the present invention, the battery body 1 includes a charging and discharging interface 11 for charging and discharging. The charging and discharging interface 11 can be used for both charging and discharging (i.e., supplying power to the electric vehicle body).

[0036] Optionally, the battery body 1 has a charging interface and a discharging interface.

[0037] According to one embodiment of the present invention, the battery module further includes a fuse and a BMS protection board, and the battery body 1 has a BMS protection board; The BMS protection board (not shown in the figure) has an auxiliary power output terminal (this is existing technology and will not be described in detail). The positive terminal of LED 21 is connected to one end of switch 3, and the other end of switch 3 is connected to the positive terminal of the auxiliary power output terminal through a fuse. The negative terminal of LED 21 is connected to the negative terminal of the auxiliary power supply output.

[0038] Specifically, the battery module also includes a power line 27, a first positive terminal connection line 5, a first negative terminal connection line 6, a second positive terminal connection line, and a second negative terminal connection line; The power cord 27 includes a protective sleeve and a positive wire and a negative wire disposed inside the protective sleeve. One end of the positive wire is connected to the positive terminal of the LED light 21, and the other end of the positive wire is connected to one end of the first positive connection wire 5. The other end of the first positive connection wire 5 is connected to one end of the switch 3. The other end of switch 3 is connected to one end of the fuse via the second positive connection line, and the other end of the fuse is connected to the positive terminal of the auxiliary power output on the BMS protection board via the third positive connection line (not shown in the figure). One end of the negative wire is connected to the negative terminal of the LED lamp 21 body, and the other end of the negative wire is connected to one end of the first negative connection wire 6. The other end of the first negative connection wire 6 is connected to the negative terminal of the auxiliary power output terminal on the BMS protection board, thereby enabling the battery body 1 to supply power to the LED lamp 21.

[0039] Preferred, such as Figure 3 As shown, the battery module includes a plug interface 8 and a connector 7. The plug interface 8 is located on the side of the battery body 1 near the receiving groove 23. The end of the first positive terminal connection line 5 away from the switch 3 and the end of the first negative terminal connection line 6 away from the BMS protection board are both connected to the plug interface 8. The heat insulation component 4 and the receiving groove 23 are respectively provided with a second clearance hole and a first clearance hole. The connector 7 is connected to the end of the power line 27 away from the LED light 21 (that is, the positive and negative terminals of the power line 27 are both connected to the connector 7). The connector 7 passes through the first clearance hole and the second clearance hole in sequence and is then plugged into the plug interface 8. By setting the insertion interface 8 on the battery casing of the battery body 1, the sealing effect of the battery casing itself can be guaranteed. Compared with the method of directly opening a hole in the battery casing to allow the first positive terminal connection wire 5 to pass through the hole in the battery casing and connect with the positive terminal wire, the sealing performance is guaranteed, making the battery module less prone to short circuit damage.

[0040] Of course, in this embodiment, the end of the third positive terminal connecting line away from the fuse can also be connected to the positive terminal of the charging and discharging interface 11, and the end of the first negative terminal connecting line 6 away from the plug interface 8 can be connected to the negative terminal of the charging and discharging interface 11, which can also enable the battery body 1 to supply power to the LED lamp 21. Its purpose has not deviated from the design concept of this utility model, and therefore, it should fall within the protection scope of this utility model.

[0041] Optionally, the battery module no longer has a separate connector 8. The connector 7 connected to the power cord 27 can be adapted to the charging and discharging interface 11. The LED light 21 can be directly removed from the receiving slot 23, and the connector 7 can be plugged into the charging and discharging interface 11 so that the battery body 1 supplies power to the LED light 21. This does not deviate from the design concept of this utility model, and therefore should fall within the protection scope of this utility model.

[0042] It should be noted that the battery body 1 also includes multiple battery packs connected in series and parallel. The positive and negative terminals of the battery packs are connected to the BMS protection board, and the BMS protection board is connected to the charging and discharging interface 11. These are all existing technologies and will not be described in detail here.

[0043] Example 2: An automobile includes a battery module and an electric vehicle body, the battery module being capable of supplying power to the electric vehicle body.
