Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] As disclosed in the background art, existing air pumps typically fix the air pump assembly structure directly with screws when installing the air pump assembly. However, due to the lack of a good limiting structure between the air pump assembly and the inner wall of the housing, it is difficult to position the air pump assembly, and the screw positioning installation is very inconvenient, which directly leads to its low assembly efficiency.

[0026] To address the aforementioned problems, this utility model provides a novel emergency air pump. The specific structure and working principle of this emergency air pump will be described in detail below.

[0027] See Figures 1 to 3 as well as Figure 7 This utility model provides an emergency air pump 100, which can better position and install the air pump assembly 130, resulting in higher assembly efficiency and better fixation.

[0028] The emergency air pump 100 provided in this embodiment of the utility model includes a housing 110, a battery 120, and an air pump assembly 130. The housing 110 has a battery compartment 111 and an inflation compartment 112, and the bottom wall of the inflation compartment 112 is provided with a locking positioning seat 140. The battery 120 is housed in the battery compartment 111. The air pump assembly 130 is housed in the inflation compartment 112 and placed on the locking positioning seat 140. The bottom side of the air pump assembly 130 is provided with a locking mounting seat 150 corresponding to the locking positioning seat 140. One of the locking mounting seat 150 and the locking positioning seat 140 is provided with a locking protrusion 141, and the other is provided with a locking groove 151. The locking protrusion 141 is correspondingly fitted into the locking groove 151 so that the air pump assembly 130 is locked and positioned in the locking positioning seat 140.

[0029] The emergency air pump 100 provided in this embodiment of the utility model can have a locking groove 151 on the locking mounting base 150 and a locking protrusion 141 on the locking positioning base 140. By assembling the locking protrusion 141 and the locking groove 151 respectively, the locking mounting base 150 can be locked onto the locking positioning base 140, and the air pump assembly 130 can be locked and positioned onto the locking positioning base 140. This can better position and install the air pump assembly 130, resulting in higher assembly efficiency and better fixing effect.

[0030] It should be noted that the bottom wall of the inflation chamber 112 mentioned in this embodiment refers to the inner wall of the outer shell 110 that carries the battery 120 and the air pump assembly 130. The bottom side of the air pump assembly 130 refers to the side of the air pump assembly 130 that is close to the bottom wall of the inflation chamber 112.

[0031] See Figures 4 to 7 Furthermore, the air pump assembly 130 includes a cylinder 131, a structural support 132, and a motor 133. Both the cylinder 131 and the motor 133 are connected to the structural support 132, and the cylinder 131 is drive-connected to the motor 133. The motor 133 is placed on a locking positioning seat 140, and a locking mounting seat 150 is located on the bottom side of the motor 133. Specifically, a transmission gear is also provided on the structural support 132. The piston rod of the cylinder 131 is connected to this transmission gear. The motor 133 drives the transmission gear to rotate, thereby pushing the piston rod of the cylinder 131 to actuate, thus achieving air pumping. The transmission structure of the cylinder 131 and the motor 133 can be referenced from existing air pump assemblies 130, and will not be described in detail here. Since the motor 133 is a vibration source, and the outer casing 110 of the motor 133 is typically cylindrical or nearly cylindrical, locking positioning of the motor 133 is necessary for rapid assembly. By providing a snap-fit ​​mounting base 150 on the bottom side of the motor 133, the motor 133 can be positioned and snapped onto the snap-fit ​​positioning base 140, thereby fixing the motor 133.

[0032] In some embodiments, the engaging mounting base 150 is an arc-shaped strip protruding from the outer wall of the motor 133, and an engaging groove 151 is formed on the engaging mounting base 150. The engaging groove 151 extends in an arc shape. The engaging positioning base 140 is provided with an engaging protrusion 141. The engaging protrusion 141 includes a first arc-shaped support plate 142 with a concave arc-shaped opening. The arc of the opening of the first arc-shaped support plate 142 is adapted to the arc of the engaging mounting base 150 and is correspondingly fitted in the engaging groove 151. Specifically, there can be two engaging mounting bases 150, both of which are arc-shaped strips distributed on the bottom outer wall of the motor 133. Each engaging mounting base 150 is provided with an engaging groove 151. At the same time, there can also be two first arc-shaped support plates 142, both of which are thin plate structures and are respectively fitted in the two engaging grooves 151 to achieve positioning.

[0033] It should be noted that the engaging mounting base 150 is distributed along the outer wall of the motor 133, and the first arc-shaped support plate 142 is also distributed along the engaging mounting base 150. This embodiment of the invention is illustrated using a cylindrical housing of the motor 133 as an example. In other embodiments of the invention, when the shape of the motor 133 changes, for example, when the motor 133 adopts an oval housing 110, the shapes of the engaging mounting base 150 and the first arc-shaped support plate 142 also change accordingly.

[0034] Furthermore, one end of the motor 133 is connected to the structural support 132 and is driven by the cylinder 131. The other end of the motor 133 is also equipped with a cooling fan 134, which can rotate under the drive of the motor 133 to provide air cooling for the motor 133 and the cylinder 131. Corresponding air inlets and outlets are provided on the opposite side walls of the outer casing 110, forming a heat dissipation channel within the inflation chamber 112 to better achieve air cooling.

[0035] In some embodiments, the engaging positioning seat 140 includes a second arc-shaped support plate 143 with a concave arc-shaped opening and vertical support plates 144 disposed at both ends of the second arc-shaped support plate 143. The vertical support plates 144 are located on both sides of the motor 133. The two ends of the first arc-shaped support plate 142 are respectively connected to the two vertical support plates 144. The second arc-shaped support plate 143 is spaced apart from the first arc-shaped support plate 142 and abuts against the outer wall of the motor 133. Specifically, the second arc-shaped support plate 143 is spaced apart from the first arc-shaped support plate 142. The arc-shaped opening size of the second arc-shaped support plate 143 is smaller than the arc-shaped opening size of the first arc-shaped support plate 142, so that the second arc-shaped support plate 143 can just abut against the outer wall of the motor 133 to support the motor 133. At the same time, the two vertical support plates 144 are parallel to each other, and the distance between them is greater than the width of the motor 133 in the same direction, so that the motor 133 can be placed between the two vertical support plates 144.

[0036] It should be noted that the second arc-shaped support plate 143 is perpendicular to the two vertical support plates 144, and the second arc-shaped support plate 143 is parallel to the two first arc-shaped support plates 142. The second arc-shaped support plate 143 and the first arc-shaped support plate 142 together provide support for the motor 133, and the first arc-shaped support plate 142 also serves to lock and position the motor 133.

[0037] Furthermore, the engaging positioning seat 140 also includes a base support plate 145, which is disposed between two vertical support plates 144 and connected to both the first arc-shaped support plate 142 and the second arc-shaped support plate 143. It serves to abut against the outer wall of the motor 133, and the base support plate 145 also has a clearance notch 147 to avoid interference with the engaging mounting seat 150. Specifically, the base support plate 145 is parallel to the two vertical support plates 144 and abuts against the bottom outer wall of the motor 133, thus providing support for the motor 133. Simultaneously, the clearance notch 147 on the base support plate 145 prevents interference between the engaging mounting seat 150 and the base support plate. Furthermore, the clearance notch 147 also limits the positioning of the engaging mounting seat 150, improving the positioning effect of the motor 133.

[0038] It should be noted that in this embodiment, the base support plate 145, the first arc-shaped support plate 142, the second arc-shaped support plate 143, and the vertical support plate 144 are all integrally disposed on the bottom wall of the air chamber 112, and the base support plate 145 is simultaneously connected to the second arc-shaped support plate 143 and the first arc-shaped support plate 142, which can improve the structural strength of the second arc-shaped support plate 143 and the first arc-shaped support plate 142.

[0039] In some embodiments, the locking positioning seat 140 is further provided with fixing mounting portions 146 on both sides, and the motor 133 is also fitted with a positioning clamp 135. The positioning clamp 135 is provided with a positioning element, which is detachably connected to the fixing mounting portion 146. Specifically, the fixing mounting portion 146 includes a fixing support column, which is located on the side of the vertical support plate 144 away from the first arc-shaped support plate 142, and the fixing support column is provided with a screw hole. The positioning element can be a screw, which passes through both ends of the positioning clamp 135 and is threaded into the screw hole, thereby fixing the motor 133. Since the motor 133 is pre-positioned by the locking protrusion 141 and the locking groove 151, the positioning clamp 135 can be accurately positioned with the fixing device, making it convenient to quickly insert the screw and achieve fixation.

[0040] In some embodiments, the bottom wall of the inflation chamber 112 is further provided with a positioning cylinder 160, which is adjacent to the engaging positioning seat 140. A silicone positioning protrusion 136 is provided on the bottom side of the structural support 132, and the silicone positioning protrusion 136 is correspondingly assembled in the positioning cylinder 160. Specifically, the positioning cylinder 160 is oval-shaped, and reinforcing ribs are provided around its perimeter to enhance its structural strength. The bottom side of the structural support 132 is positioned by the alignment and cooperation between the silicone positioning protrusion 136 and the positioning cylinder 160. Furthermore, the use of the silicone positioning protrusion 136 ensures its secure assembly in the positioning cylinder 160 and provides a larger installation allowance, guaranteeing the alignment and assembly between the engaging protrusion 141 and the engaging groove 151. This also reduces the assembly precision requirements between the structural support 132 and the motor 133, thus reducing assembly difficulty.

[0041] Furthermore, the positioning cylinder 160 is also provided with structural ribs, which are distributed in a cross shape. The structural ribs can abut against the silicone positioning protrusions 136 to support the structural bracket 132 and also enhance the structural strength of the positioning cylinder 160.

[0042] In some embodiments, the outer casing 110 includes a bottom casing 113 and a top casing 114. The top casing 114 is detachably mounted on the bottom casing 113 and forms an internal cavity. A locking positioning seat 140 is disposed on the bottom casing 113. A partition plate 115 is also provided in the middle of the bottom casing 113, dividing the internal cavity into an inflation chamber 112 and a battery compartment 111. Specifically, the two sides of the partition plate 115 extend to two opposite sidewalls of the internal cavity, and at least one side of the partition plate 115 is provided with a reinforcing rib. By providing the partition plate 115, the inflation chamber 112 and the battery compartment 111 can be effectively separated, preventing high-speed components in the inflation chamber 112 from accidentally falling into the battery compartment 111 and damaging the battery 120.

[0043] It should be noted that the top shell 114 is also equipped with a display screen that can display information such as the power and air pressure of the emergency air pump 100. Additionally, the top shell 114 and the bottom shell 113 are equipped with side lights, which are connected to the battery 120 and provide illumination.

[0044] See Figure 8 In some embodiments, the emergency air pump 100 further includes an air pump tube 170, one end of which is connected to the air pump assembly 130, and the other end extends out of the housing 110 and is provided with an air nozzle 171. The portion of the air pump tube 170 extending out of the housing 110 is housed on the bottom side of the housing 110. Specifically, the air pump tube 170 is a flexible hose, and the side wall of the housing 110 is provided with a clearance hole. One end of the air pump tube 170 is connected to the air outlet of the cylinder 131, and the other end passes through the clearance hole and is housed on the side of the bottom housing 113 away from the top housing 114. When needed, the air pump tube 170 can be removed from the bottom housing 113 and its direction adjusted as required. The air nozzle 171 is located at the end of the air pump tube 170 and can be connected to the vehicle's valve.

[0045] Furthermore, a curved and extended pipe storage groove 172 is provided on the bottom side of the outer casing 110. One end of the pipe storage groove 172 extends to the side wall of the outer casing 110, and the other end is provided with a retrieval storage groove 173. The portion of the air pump pipe 170 that protrudes from the outer casing 110 is correspondingly stored in the storage groove, and the air nozzle 171 is correspondingly stored in the retrieval storage groove 173. Specifically, the bottom side of the bottom shell 113 is partially concave to form the pipe storage groove 172, and the pipe storage groove 172 is spirally distributed to accommodate the longest possible length of the air pump pipe 170. The side wall of the pipe storage groove 172 is provided with a stop protrusion to limit the air pump pipe 170, and the side wall of the retrieval storage groove 173 is also provided with a locking protrusion to lock the air nozzle 171. Furthermore, the storage slot 173 is also provided with a take-up extension port, which does not accommodate the air nozzle 171. When removing the air nozzle 171, you can reach into the take-up extension port and pull to remove the air nozzle 171.

[0046] See Figure 1 and Figure 8 In some embodiments, a cigarette lighter 180 is also embedded in the side wall of the housing 110. The cigarette lighter 180 is connected to the battery 120, and an emergency ignition function can be realized through the cigarette lighter 180. Specifically, an electronic control board is also provided inside the housing 110. The electronic control board is located in the battery compartment 111. One end of the cigarette lighter 180 extends into the housing 110 and is connected to the electronic control board, while the other end is exposed on the side wall of the housing 110. The electronic control board is electrically connected to the battery 120.

[0047] In summary, the emergency air pump 100 provided in this embodiment of the present invention has a battery compartment 111 and an air chamber 112 separated from each other within the outer casing 110. The bottom wall of the air chamber 112 is provided with a locking positioning seat 140. The battery 120 is housed within the battery compartment 111, and the air pump assembly 130 is housed within the air chamber 112 and placed on the locking positioning seat 140. The bottom side of the air pump assembly 130 is provided with a locking mounting seat 150. The locking mounting seat 150 and the locking positioning seat 140 are correspondingly engaged, with one of them having a locking protrusion 141 and the other a locking groove 151. The locking protrusion 141 and the locking groove 151 cooperate accordingly, thereby locking and positioning the air pump assembly 130 on the locking positioning seat 140. This embodiment of the invention achieves the engagement of the engaging mounting base 150 onto the engaging positioning base 140 by correspondingly assembling the engaging protrusion 141 and the engaging groove 151. It also achieves the engagement and positioning of the motor 133 of the air pump assembly 130 onto the engaging positioning base 140, enabling better positioning and installation of the air pump assembly 130, resulting in higher assembly efficiency and better fixation. Simultaneously, the positioning clamp 135 further enhances the positioning and fixation of the motor 133. The structural bracket 132 can be positioned using the positioning cylinder 160, further improving the positioning effect.
