Description

Technical Field

[0001] This utility model relates to the field of air pumps, specifically a miniature multifunctional air pump. Background Technology

[0002] For modern motor vehicles, air pumps have almost become an essential car accessory, used to inflate tires when they are low.

[0003] Currently, air pumps are typically included in an emergency kit by car manufacturers. Besides the air pump, the emergency kit usually also contains a flashlight, window breaker, etc. However, this configuration has two problems: First, the emergency kit is relatively large, taking up considerable space inside the vehicle. Therefore, it is usually placed in the trunk. However, placing the emergency kit in the trunk can make it difficult to quickly access the air pump or window breaker in an emergency, thus posing a safety hazard to passengers. Second, storing emergency equipment such as the air pump, flashlight, or window breaker separately in the emergency kit makes them extremely easy to lose. This is especially true for smaller devices like the flashlight and window breaker, which are often forgotten to be put back in the emergency kit after use, creating a potential hazard in future emergencies.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, a miniature multifunctional air pump includes a hollow cylindrical housing 100. A control component 200 is disposed inside the housing 100. A first end cap 110 covers one end of the housing 100, and an air injection hole 112 is provided on the first end cap 110. A pump body assembly 300 is connected inside the air injection hole 112. The pump body assembly 300 is used to discharge air from the air injection hole 112. A lighting component 400 is disposed inside the housing 100 at the end of the control component 200 away from the pump body assembly 300. The control component 200 is electrically connected to both the pump body assembly 300 and the lighting component 400. A battery pack 500 is disposed between the pump body assembly 300 and the control component 200. The battery pack 500 is used to supply power to the control component 200, the pump body assembly 300, and the lighting component 400.

[0027] This application pertains to automotive parts and is primarily used for inflating automotive tires. In the working state of this embodiment, the tire and the inflation port 112 are first connected by an air hose. Then, the pump assembly 300 is activated by the control component 200 on the operating housing 100, thereby expelling air from the inflation port 112 to inflate the tire. Simultaneously, when external lighting is required, the lighting assembly 400 can be activated by the control component 200 on the operating housing 100 to illuminate the outside world.

[0028] This application arranges the pump assembly 300, battery pack 500, control assembly 200 and lighting assembly 400 in a series connection on a slender cylindrical housing 100. In addition, it combines the functions of air inflation, lighting and window breaking. Compared with the traditional box-type layout, this application realizes multiple functions with a single device, while also saving more space in the vehicle.

[0029] Furthermore, based on the above embodiments, such as Figure 2As shown, the pump assembly 300 includes a rotary motor 310, which is electrically connected to the battery pack 500. A straight bevel gear 320 is sleeved on the drive end of the rotary motor 310. A transmission gear 330 meshes with the straight bevel gear 320 on the side away from the rotary motor 310. An eccentric shaft 340 is provided on the transmission gear 330, and a piston rod 350 is sleeved on the eccentric shaft 340. A cylinder 360 is provided between the rotary motor 310 and the first end cover 110. One end of the cylinder 360 is the same as the air inlet 112, and the other end is inserted by the piston rod 350. When inflating the tire, the rotary motor 310 is started to drive the straight bevel gear 320 to rotate, thereby driving the transmission gear 330 to drive the piston rod 350 to move within the cylinder 360, thereby expelling the air from the cylinder 360 through the air inlet and inflating the tire.

[0030] Furthermore, based on the above embodiments, such as Figure 2 As shown, a plurality of vent holes 113 are provided on the first end cap 110, and air inlets 361 are provided on both sides of the cylinder body 360. The vent holes 113 and the air inlets 361 are interconnected. When the piston rod 350 moves inside the cylinder body 360, thereby expelling the air inside the cylinder body 360 from the air pump hole, a negative pressure is formed between the cylinder body 360 and the rotary motor 310. Thus, external air can enter the space between the cylinder body 360 and the rotary motor 310 through the vent holes 113 and the air inlets 361, and then re-enter the cylinder body 360. Then, as the piston rod 350 moves inside the cylinder body 360, the air inside the cylinder body 360 is expelled from the air pump hole again.

[0031] Furthermore, based on the above embodiments, such as Figure 2 As shown, a sealing ring 370 is also provided between the first end cap 110 and the cylinder 360. The sealing ring 370 is used to prevent gas in the cylinder 360 from flowing out from the gap of the first end cap 110 when the pump assembly 300 is pumping air, thereby affecting the pumping efficiency.

[0032] Furthermore, based on the above embodiments, such as Figure 3 As shown, the lighting assembly 400 includes an LED light panel 410, which is electrically connected to the control assembly 200. A reflector 420 is provided on the side of the LED light panel 410 away from the control assembly 200. When the LED beads on the LED light panel 410 are activated by the control assembly 200 on the operating housing 100, the light is concentrated and made more efficient by the reflector 420.

[0033] Furthermore, based on the above embodiments, such as Figure 3As shown, the lighting assembly 400 also includes a second end cap 430, which is connected to the other end of the housing 100. The second end cap 430 has several protrusions 431 protruding outward. The protrusions 431 are made of silicon nitride. In this way, when the vehicle encounters an emergency and the window cannot be opened, the second end cap 430 can be aligned with the window, and the protrusions 431 can be used to strike the window to break the window.

[0034] Furthermore, based on the above embodiments, such as Figure 4 As shown, the control component 200 includes a control circuit board 210, a display 220, and operation buttons 230. The control circuit board 210 is disposed inside the housing 100, and the display 220 and operation buttons 230 are electrically connected to the control circuit board 210.

[0035] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
