Description

Technical Field

[0001] The utility model relates to a heat dissipation structure of a vehicle-mounted air pump. Background Art

[0002] In the prior art, the air pump includes a motor, a transmission assembly, a piston rod, a one-way valve and a cylinder. The principle is that the motor drives the transmission assembly to make the piston rod reciprocate in the cylinder to realize the inflation function. A spring is provided on one side of the piston rod in the cylinder. When air is pumped out, the external gas pushes the spring from the other side of the piston rod and enters the cylinder. When air is inflated, the spring of the piston rod closes, and the gas in the cylinder is squeezed and opens the one-way valve at the end of the cylinder to enter the inflatable object.

[0003] However, the existing air pumps still have some shortcomings: since the air pump has a large internal space in the shell, has many parts and a complex structure, the airflow is likely to generate vortices and turbulence inside the cavity during inflation, which in turn affects the smoothness of the air outlet. At the same time, the vibration generated by the inflation will also cause the internal components to shake and loosen. The internal structure assembly is not stable enough and is likely to generate greater noise due to vibration. This will also increase the power consumption of the motor and increase the temperature inside the shell, affecting the battery life and life of the circuit board and battery. The heat dissipation is insufficient and needs to be improved urgently. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a vehicle-mounted air pump heat dissipation structure, which not only has a reasonable structure but also has a stable internal structure and a better heat dissipation effect.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a vehicle-mounted air pump heat dissipation structure, including an outer cover shell, in which two assembly shells that are plugged in opposite directions to fix the air pump body are arranged, the top cover of the assembly shell is provided with a heat dissipation top cover, and the heat dissipation top cover is vertically penetrated with a plurality of strip-shaped heat dissipation holes on the near edge side, an annular clamping ring is fixed at the lower end of the heat dissipation cover, and a plurality of trapezoidal clamping blocks are protruded at intervals along the circumference of the outer bottom of the clamping ring, and the top of the assembly shell is provided with a bayonet for clamping with the trapezoidal clamping blocks, the outer circumferential size of the heat dissipation top cover is larger than the outer circumferential size of the top of the two assembly shells after assembly to form a limit step at the docking end, the top of the outer cover shell is open and the top is provided with an annular limit groove along its inner circumference to connect with the limit step, and the bottom of the assembly shell is fastened to the bottom of the outer cover shell by screws.

[0006] Furthermore, the heat dissipation holes are extended to form a ring-like integrated hole, and the integrated hole is proportionally reduced to the outer periphery of the heat dissipation top cover.

[0007] Furthermore, a plurality of plug rods protrude from one of the assembly shells, and corresponding plug tubes that are plugged with the plug rods protrude from the other assembly shell, and screw holes are provided on both assembly shells to fix the two assembly shells.

[0008] Furthermore, a plurality of heat dissipation square holes are arranged in an array at the side ends of the two assembled shells, and an anti-dropping clip is fixed on the opposite end surface of one of the assembled shells to be engaged with the heat dissipation square holes on the other assembled shell.

[0009] Furthermore, the heat dissipation top cover is provided with an inflation hole for facilitating inflation and an installation bayonet for facilitating installation of the lighting lamp.

[0010] Furthermore, the air pump body includes a heat dissipation fan located at the bottom of the outer cover shell, and the bottom and sides of the outer cover shell are provided with ventilating holes in an array to facilitate ventilation.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by adding an assembly shell, the stability of the internal parts assembly is strengthened, and at the same time, the cooperation with the heat dissipation top cover and the limit step further ensures the stability and aesthetics. The setting of the heat dissipation holes, the heat dissipation square holes and the vents can better dissipate the heat of internal components such as the cylinder, and the heat dissipation effect is significantly improved.
