Description

Technical Field

[0001] The utility model relates to the technical field of automotive power supply jumper clips, in particular to a safety-type clip assembly. Background Art

[0002] In modern automotive applications, the stability of the power system is directly related to the normal startup and driving safety of the vehicle. When the automotive battery runs out of power due to long-term non-use, battery aging, or circuit faults, the vehicle cannot be started in the conventional way. At this time, using an external emergency power supply for jump-starting becomes a common emergency measure. As a key component connecting the automotive battery and the external emergency power supply, the safety and functionality of the design of the jumper clip are particularly important. The existing jumper clip designs have fully considered the potential safety hazards during operation and are generally equipped with built-in protection devices. The protection device consists of a clip plate, a relay, an LED display light, a buzzer, and a housing. The clip plate is connected to the alligator clip through a cable. The relay in the protection device can detect the current and voltage parameters in the circuit and can intelligently control the on-off of the circuit, thus realizing functions such as short-circuit protection, reverse connection protection, and reverse charging protection. When an abnormal situation is detected, the relay will quickly cut off the circuit to prevent further damage. The LED display light, as a visual indicator, can intuitively reflect the working state of the current circuit. During the jump-starting process, the LED light can display whether the circuit is connected and whether there is current passing through. At the same time, when short-circuit or reverse connection abnormal situations occur, the LED light will also emit corresponding warning signals. The buzzer, as an auditory warning device, will emit a sound alarm when an abnormal situation is detected to remind the operator to pay attention. The positive alligator clip is connected to the positive input terminal inside the protection device through a special cable, and the negative alligator clip is also connected to the negative input terminal inside the protection device through a special cable;

[0003] In the actual application of the alligator clip, dust is likely to adhere to the clamping area between its terminal and the power supply connector. If it is not cleaned in time due to negligence during use, when the alligator clip is connected to the power supply connector, problems such as poor contact or short circuit will occur.

[0004] To solve the above problems, a safety-type clip assembly is proposed in this application. Summary of the Invention

[0007] A cable is connected to the alligator clip, and the end of the cable far from the alligator clip is connected to a male plug;

[0008] A protection device is installed on the cable.

[0009] A balloon member is installed inside the gripping end of the alligator clip, and a blowing member is installed outside the alligator clip. The blowing member is communicated with the balloon member and is arranged towards the inside of the clamping end of the alligator clip, and the blowing member is used to blow air towards the inside of the clamping end of the alligator clip.

[0010] Preferably, the balloon member includes an elastic balloon. The elastic balloon is installed inside the gripping end of the alligator clip. A trachea communicated with the elastic balloon is connected to the elastic balloon, and one end of the trachea far away from the elastic balloon is communicated with the blowing member.

[0011] Preferably, the blowing member includes a blowing cylinder. The blowing cylinder is installed outside the alligator clip. A cavity is formed inside the blowing cylinder. One end of the trachea far away from the elastic balloon is connected to the outer periphery of the blowing cylinder, and the trachea is communicated with the cavity.

[0013] Preferably, the number of the alligator clips is two, and the two alligator clips are a positive electrode clip and a negative electrode clip respectively.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] By arranging the balloon member and the blowing member, when the alligator clip is connected to the vehicle power supply, pressure can be applied to the gripping end of the alligator clip. Under the action of the pressure, the two handles at the gripping end of the alligator clip approach each other, thereby squeezing the balloon member. After the balloon member is subjected to pressure, the gas inside is conducted to the blowing member, and the blowing member can blow the gas towards the inside of the clamping end of the alligator clip, so that the dust at the clamping end of the alligator clip can be blown away. This structure can utilize the pressure applied to the balloon member by gripping the alligator clip to conduct the gas to the blowing member and blow it towards the clamping end of the alligator clip, realizing the cleaning of the dust at the clamping end of the alligator clip, realizing the automatic cleaning function, and effectively preventing the problems of poor contact or short circuit caused by dust accumulation in the clamping area of the alligator clip.

It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0022] As Figure 1-4 shown, a safety clip assembly proposed by the present utility model includes an alligator clip 1;

[0023] In this embodiment, a cable 2 is connected to the alligator clip 1, and a male plug 3 is connected to one end of the cable 2 away from the alligator clip 1.

[0024] In this embodiment, a protection device 4 is installed on the cable 2. The protection device 4 includes a front shell 41 and a bottom shell 42 connected to the front shell 41. An assembly chamber is formed inside the front shell 41 and the bottom shell 42. The cable 2 passes through the assembly chamber. A clip plate 43 connected to the cable 2 is installed inside the front shell 41 and the bottom shell 42, and a relay 44, a buzzer 45 and an LED display lamp 46 are installed on the clip plate 43.

[0025] In this embodiment, the number of alligator clips 1 is two, and the two alligator clips 1 are respectively a positive clip and a negative clip.

[0026] It should be noted that when charging the vehicle power supply, the male plug 3 on the cable 2 needs to be connected to the power supply, and then the alligator clip 1 is clamped on the connector of the vehicle power supply. During the charging process, the relay 44 can intelligently control the on-off of the circuit by detecting the current and voltage parameters in the circuit, so as to realize the functions of short-circuit protection, reverse connection protection, and reverse charging protection. When an abnormal situation is detected, the relay 44 will quickly cut off the circuit to prevent further damage. The LED display lamp 46 is used as a visual indicator, and it can intuitively reflect the working state of the current circuit. During the power connection process, the LED display lamp 46 can display information such as whether the circuit is connected and whether there is current passing through. At the same time, when short-circuit or reverse connection abnormal situations occur, the LED display lamp 46 will also emit corresponding warning signals. The buzzer 45 is used as an audible warning device, and it will emit a sound alarm when an abnormal situation is detected to remind the operator to pay attention. This is the prior art and will not be elaborated too much.

[0027] In this embodiment, a balloon member 5 is installed inside the holding end of the alligator clip 1, and a blowing member 6 that is connected to the balloon member 5 and is arranged toward the inside of the clamping end of the alligator clip 1 is installed outside the alligator clip 1, and the blowing member 6 is used to blow air toward the inside of the clamping end of the alligator clip 1.

[0028] In this embodiment, the balloon member 5 includes an elastic balloon 51. The elastic balloon 51 is installed inside the holding end of the alligator clip 1. A gas guide pipe 52 that is connected to and communicates with the elastic balloon 51 is connected to the elastic balloon 51. The end of the gas guide pipe 52 away from the elastic balloon 51 is connected to the blowing member 6. The blowing member 6 includes a blowing cylinder 61. The blowing cylinder 61 is installed outside the alligator clip 1. A cavity is formed inside the blowing cylinder 61. The end of the gas guide pipe 52 away from the elastic balloon 51 is connected to the outer periphery of the blowing cylinder 61 and is in communication with the cavity. A blowing nozzle 62 that is in communication with the cavity is connected to the top end of the blowing cylinder 61, and the blowing nozzle 62 is arranged toward the inside of the clamping end of the alligator clip 1.

[0029] It should be noted that when connecting the alligator clip 1 to the vehicle power supply, pressure can be applied to the holding end of the alligator clip 1. Under the action of the pressure, the two handles at the holding end of the alligator clip 1 approach each other, thereby squeezing the elastic balloon 51. After the elastic balloon 51 is subjected to pressure, the gas inside it is guided through the gas guide pipe 52 into the blowing cylinder 61, and the gas can be blown toward the inside of the clamping end of the alligator clip 1 through the blowing nozzle 62 on the blowing cylinder 61, so that the dust at the clamping end of the alligator clip 1 can be blown away. This structure can utilize the pressure applied to the balloon member 5 by holding the alligator clip 1 to guide the gas into the blowing member 6 and blow it toward the clamping end of the alligator clip 1, realizing the cleaning of the dust at the clamping end of the alligator clip 1, achieving the automatic cleaning function, and effectively preventing problems such as poor contact or short circuit caused by dust accumulation in the clamping area of the alligator clip 1.
