There are different types of vehicle-mounted chargers on the market, such as portable, fixed, slow charging, and fast charging. However, there are few vehicle-mounted chargers on the market that can have a high-temperature alarm. Therefore, a vehicle-mounted charger with smoke and high-temperature alarm is needed.

[0003] The Chinese patent provides a vehicle-mounted charger with a publication number of CN206640331U, which includes a housing; a circuit board fixed inside the housing; a positive electrode assembly and a negative electrode assembly fixed on the circuit board and electrically connected to the circuit board. Among them, the positive electrode assembly includes the positive electrode bullet cap, the negative electrode assembly includes the negative electrode bullet ear, and the positive electrode bullet cap and the negative electrode bullet ear are telescopically installed on the housing; and an insulating limiting member arranged between the positive electrode assembly and the negative electrode assembly, and the insulating limiting member is made of insulating material.

[0004] The above device can prevent the negative electrode assembly from forming an electrical connection with the positive electrode assembly when the force is uneven or the aging deformation occurs, resulting in a short-circuit phenomenon. However, when the device is in use, the positive electrode bullet cap and the negative electrode bullet ear of the vehicle-mounted charger are both exposed on the outer wall of the charger housing, which are easily worn and damaged. Without installing corresponding protective structures, when worn to a certain extent, it will affect the normal use of the vehicle-mounted charger. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a vehicle-mounted charger with smoke and high-temperature alarm, which can effectively solve the technical problem that the positive electrode bullet cap and the negative electrode bullet ear of the vehicle-mounted charger in the background art are both exposed on the outer wall of the charger housing and are easily worn and damaged.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A vehicle-mounted charger with smoke and high-temperature alarm includes a housing. A positive electrode bullet cap is arranged at the top of the housing. Two negative electrode bullet ears are opened on the outer wall of the housing. Two charging interfaces are opened at the bottom of the housing. A first sleeve is fixedly installed on the outer wall of the housing. Two through grooves are opened on the outer wall of the first sleeve. A second sleeve is arranged at the top of the first sleeve. Two grooves are opened on the outer wall of the second sleeve.

[0008] As a further solution of the present utility model, two elastic blocks are fixedly installed on the outer wall of the housing, and one end of the elastic block is adaptively matched with the groove. Two springs are fixedly installed at the bottom of the second sleeve, and the bottom of the spring is fixedly connected to the outer wall of the housing.

[0009] As a further solution of the present utility model, four connecting rods are fixedly installed at the bottom of the second sleeve, and the connecting rods penetrate through the housing.

[0010] As a further solution of the present utility model, two fixing blocks are fixedly installed at the bottom of the outer wall of the housing. Two connecting blocks are fixedly installed at the bottom of the fixing blocks. A rotating block is rotatably connected to the adjacent surfaces of the two connecting blocks.

[0011] As a further solution of the present utility model, baffles are fixedly installed on the adjacent surfaces of the two rotating blocks. A limiting block is fixedly installed on the outer wall of one side of the front baffle. A limiting groove is formed on the outer wall of one side of the rear baffle, and the limiting groove is adaptively matched with the limiting block.

[0012] As a further solution of the present utility model, a smoke sensor is provided on the inner wall of the housing, and a temperature sensor is provided on the inner wall of the housing.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1) For this vehicle-mounted charger with smoke and high-temperature alarms, by pressing down the second sleeve until the groove formed on the outer wall of the second sleeve is engaged with one end of the elastic block. At this time, the top of the second sleeve is located at the bottom of the negative electrode ear. After charging is completed, press the elastic block to release the restriction between the elastic block and the groove. The spring will rebound from the compressed state, and the second sleeve will be reset to its initial position. The second sleeve can cover the positive electrode cap and the negative electrode ear, which can reduce unnecessary wear and extend the service life of the vehicle-mounted charger.

[0015] 2) For this vehicle-mounted charger with smoke and high-temperature alarms, when the second sleeve is pressed down, the connecting rods move downward synchronously. When the second sleeve cannot be pressed down further, the connecting rods will push open the two baffles. After the two baffles are pushed open, the charging interface will be exposed. After charging is completed, the second sleeve rebounds, and the baffles are rotated. When the two baffles are on the same horizontal line, the limiting groove will be engaged with the limiting block, and then the two baffles will be engaged with each other, which can prevent foreign substances from penetrating into the charging interface, causing poor contact and affecting the normal use of the vehicle-mounted charger.

The second sleeve 7 and the outer shell 1 can be connected together by the spring 10. When the second sleeve 7 is pressed down, the four connecting rods 11 can be driven to move downward, pushing open the two baffles 15.

[0026] Embodiment 2

[0027] Refer to Figure 3 and Figure 4 On the basis of Embodiment 1, it is further obtained that two fixing blocks 12 are fixedly installed at the bottom of the outer wall of the housing 1. Two connecting blocks 13 are fixedly installed at the bottom of the fixing blocks 12. A rotating block 14 is rotatably connected to the adjacent surfaces of the two connecting blocks 13. Baffles 15 are fixedly installed on the adjacent surfaces of the two rotating blocks 14. A limiting block 16 is fixedly installed on the outer wall of one side of the front baffle 15.
