Description

TECHNICAL FIELD

[0001] The utility model relates to a vehicle-mounted air pump, especially to an efficient and energy-saving vehicle-mounted air pump. BACKGROUND

[0002] The vehicle-mounted air pump (also called as automobile air pump or automobile air pump) is a small air filling device specially designed for automobile, which can be used to fill air into tires, balls, air cushions, air beds and other objects, and the biggest advantage of the vehicle-mounted air pump is that the owner can quickly repair the tire pressure problem on the way, which can avoid being stranded on the roadside due to tire leakage. In order to facilitate the carrying and use of the vehicle-mounted air pump, the vehicle-mounted power supply or the storage battery can be directly arranged in the vehicle-mounted air pump.

[0003] In the prior art, the patent with the publication number CN218522778U named air pump is disclosed, which stores the air filling assembly in the shell, fully utilizes the internal space of the air pump, effectively reduces the volume of the air pump, realizes the purpose of small and portable air pump, and avoids the problem of easy loss or damage of the air filling assembly when it is stored alone, and effectively guarantees the reliability of the air filling assembly and the air pump.

[0004] However, it still has some deficiencies. For example, during the air filling process of the vehicle-mounted air pump, the driving motor and the storage battery for supplying power to the driving motor are prone to heating. Although in the common vehicle-mounted air pump, in order to enable the heat to be dissipated from the shell, a plurality of heat dissipation holes are arranged at the shell where the driving motor and the storage battery are located, and in order to improve the heat dissipation effect, a heat dissipation fan is also arranged in the vehicle-mounted air pump. When the heat dissipation fan works, the gas flow speed in the vehicle-mounted air pump is accelerated, thereby realizing the effect of improving the heat dissipation. However, when the driving motor and the storage battery are installed in the vehicle-mounted air pump, the surface of the driving motor and the storage battery directly abuts against the shell of the vehicle-mounted air pump. Therefore, the part of the driving motor and the storage battery abutting against the shell of the vehicle-mounted air pump cannot be in contact with the flowing gas flow, which reduces the heat dissipation effect of the driving motor and the storage battery. As a result, the continuous use of the vehicle-mounted air pump is affected, and the service life of the vehicle-mounted air pump is also reduced. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0029] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and those skilled in the art will appreciate that the description is only descriptive, exemplary, and should not be interpreted as limiting the protection scope of the utility model.

[0030] It should be noted that: similar reference numerals represent similar items in the following drawings, so once an item is defined in one drawing, it can not be further defined and explained in the subsequent drawings.

[0031] The embodiment mainly describes the structure of the high-efficiency energy-saving vehicle-mounted air pump, which is as follows:

[0032] As Figures 1-12 shown, the high-efficiency energy-saving vehicle-mounted air pump comprises a shell 1, a storage battery 7 and a driving motor 3 electrically connected with the storage battery 7 installed in the shell 1, and further comprises an air pump 8 and a heat dissipation fan 5 arranged in the shell 1, then a gear transmission device 6 is arranged at the output end of the driving motor 3, and the gear transmission device 6 is connected with the piston 81 in the air pump 8;

[0033] When the vehicle air pump is working, the battery 7 supplies power to the drive motor 3, causing the drive motor 3 to rotate. As the drive motor 3 rotates, its output can drive the gear transmission device 6. The gear transmission device 6 can drive the piston 81 in the air pump 8 to move back and forth in the air pump 8, thus enabling the vehicle air pump to inflate. In order to ensure the continuous use of the vehicle air pump, the cooling fan 5 also starts working when the drive motor 3 is working to cool the drive motor 3 and the battery 7. In order to improve the sealing of the piston 81 when it moves in the air pump 8, at least two sealing rings 82 are provided on the side wall where the piston 81 abuts against the inner wall of the cylinder, and the sealing rings 82 abut against the inner wall of the cylinder.

[0034] In order to facilitate heat dissipation of the drive motor 3 and the battery 7, multiple first through slots 12 and second through slots 11 communicating with the interior of the housing 1 are respectively provided at the top and bottom of the housing 1. The cooling fan 5 is located above the second through slot 11 in the housing 1, while the drive motor 3 and the battery 7 are located below the first through slot 12 in the housing 1. In this way, when the drive motor 3 starts, the cooling fan 5 installed in the housing 1 also starts, so that the air outside the vehicle air pump can enter the housing 1 from the second through slot as the cooling fan 5 rotates. As the air in the housing 1 moves, the heat generated when the drive motor 3 and the battery 7 are working can be carried away. Then the air carrying heat can leave the vehicle air pump through the first through slot 12 at the top of the housing 1.

[0035] Meanwhile, in order to improve the contact range of the moving air in the shell 1 with the surfaces of the driving motor 3 and the battery 7, a heat dissipation sleeve 4 made of heat-conductive material is sleeved on the outer side of the driving motor 3 and the battery 7, so that the heat on the driving motor 3 and the battery 7 can be transferred to the heat dissipation sleeve 4, the heat dissipation sleeve 4 made of heat-conductive material can improve the heat transfer effect on the heat dissipation sleeve 4, and the outer side of the heat dissipation sleeve 4 is connected and fixed with the inside of the shell 1, so that the surfaces of the driving motor 3 and the battery 7 can avoid direct contact with the shell 1, and the heat dissipation sleeve 4 comprises a sleeve body 41 sleeved on the driving motor 3 and the battery 7, the sleeve body 41 is hollow, and a plurality of first heat dissipation holes 42 penetrating through the sleeve body 41 are uniformly arranged on the outer wall of the sleeve body 41, and a plurality of second heat dissipation holes 44 communicating with the inside of the sleeve body 41 are uniformly arranged on the end walls at both ends of the sleeve body 41, so that when the air moves in the shell 1, it can enter the cavity in the sleeve body 41 through the first heat dissipation holes 42 and the second heat dissipation holes 44 and fully contact with the inner wall of the sleeve body 41, and the air in the cavity can leave the sleeve body 41 through the first heat dissipation holes 42 and the second heat dissipation holes 44, so that the heat transferred from the driving motor 3 and the battery 7 to the heat dissipation sleeve 4 can be taken away by the air moving in the cavity of the sleeve body 41, so that the arrangement of the cavity, the first heat dissipation holes 42 and the second heat dissipation holes 44 in the sleeve body 41 can improve the contact range of the moving air in the shell 1 with the surfaces of the driving motor 3 and the battery 7, thereby improving the heat dissipation effect of the driving motor 3 and the battery 7, and facilitating the continuous use of the vehicle-mounted air pump and prolonging the service life of the vehicle-mounted air pump.

[0036] In order to ensure the firmness of the sleeve connection of the heat dissipation sleeve 4 with the driving motor 3 and the battery 7, a plurality of abutting blocks 43 made of elastic material are uniformly arranged on the inner wall of the sleeve body 41, and the abutting blocks 43 respectively abut against the outer wall of the driving motor 3 or the outer wall of the battery 7, so that when the sleeve body 41 is sleeved with the driving motor 3 and the battery 7, the outer wall of the driving motor 3 and the battery 7 can extrude the abutting blocks 43, and since the abutting blocks 43 are made of elastic material, when the abutting blocks 43 are extruded, the abutting blocks 43 can generate a force opposite to the extrusion direction, so as to ensure the firmness of the sleeve connection of the heat dissipation sleeve 4 with the driving motor 3 and the battery 7, and in order to ensure the elastic effect of the abutting blocks 43, an installation cavity 431 is arranged in each abutting block 43, and a plurality of springs 432 are arranged in the installation cavity 431.

[0037] Further, in order to reduce the volume of the vehicle-mounted air pump, the driving motor 3 is a double-shaft motor, that is, the top and bottom of the driving motor 3 each has an output shaft, so that the output shaft at the top of the driving motor 3 is connected with the gear transmission device 6, and the output shaft at the bottom of the driving motor 3 is connected with the heat dissipation fan 5, so that when the driving motor 3 works, the gear transmission device 6 and the heat dissipation fan 5 can work at the same time.

[0038] In order to facilitate the connection of the air pump and the inflation tube, the connecting head 2 is arranged at the end of the air pump 8 away from the gear transmission device 6, and the connecting head 2 comprises a cylinder 21 connected with the air pump 8, and the cylinder 21 is in communication with the inside of the air pump 8, and an inner thread 22 is arranged on the inner wall of the cylinder 21, and a mounting table is arranged at one end of the cylinder 21 close to the air cylinder, and a sealing ring 23 is arranged on the mounting table, so that when the inflation tube is connected with the connecting head 2, a screw sleeve capable of being screwed with the inner thread 22 in the cylinder 21 is first arranged on the inflation tube, and then the screw sleeve is screwed into the cylinder 21 together with the inflation tube until the sealing ring 23 on the mounting table is abutted, so that the firmness and the sealing property of the connection of the inflation tube and the connecting head 2 are ensured.

[0039] Further, in order to avoid the problem that the sealing ring 23 is separated from the connecting head 2 when the inflation tube is not connected with the connecting head 2, a mounting groove 24 matched with the sealing ring 23 is arranged on the mounting table, and the sealing ring 23 is located in the mounting groove 24, and a limiting ring 231 is arranged on the side wall of the sealing ring 23, and a limiting groove 241 matched with the limiting ring 231 is arranged on the side wall of the mounting groove 24, and the limiting ring 231 is abutted with the limiting groove 241.
