Description

Technical Field

[0001] The invention belongs to the technical field of power vehicles, in particular to a manual air power vehicle inflation device. Background Art

[0002] An aerodynamic vehicle, also known as a pneumatic car, is a technological device that uses air pressure to drive the vehicle forward. Although a wide variety of aerodynamic vehicles and their supporting inflatable devices have emerged on the market, these products have met users' needs for convenient and efficient inflation to a certain extent. However, many advanced inflatable devices rely on electric drive. They obtain energy by connecting to household power or car cigarette lighters, thereby achieving fast and efficient inflation effects, but they are unable to do so in certain scenarios. For example, when camping in the wild, driving long distances through uninhabited areas, or encountering power outages caused by natural disasters, the lack of external power will directly limit the use of these inflatable devices, leaving users facing the dilemma of being unable to refill tires or inflatable equipment in time. In view of the above-mentioned limitations of power dependence, many users turn to manual air pumps as a power source. Manual air pumps do not require external power and can be operated by manpower alone, greatly improving the portability and applicability of inflatable devices.

[0003] However, during long-term use, manual air pumps also face severe tests of durability. During transportation, external factors such as vehicle bumps and luggage squeezing may cause the internal parts of the air pump to loosen. The seals inside the air pump are core components that maintain gas pressure and ensure airtightness. Faced with continuous pressure changes and environmental erosion, they may age, harden or break. Once the seals fail, it will not only affect the inflation ability of the air pump, but may also cause mechanical failures, causing the air pump to completely lose its function, which not only increases the user's maintenance costs, but also affects the overall service life of the inflation device and user experience. Therefore, they need to be improved and optimized. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a manual pneumatic vehicle inflation device, which solves the problems of short service life and poor user practical experience.

[0005] To achieve the above object, the present invention provides the following technical solution: a manual air-powered vehicle inflator, comprising a placement box, a damping plate is slidably mounted inside the placement box, an air pump is arranged on the top of the damping plate, and a damping mechanism is arranged on the bottom of the damping plate;

[0006] The shock absorbing mechanism includes shock absorbing component 1 and shock absorbing component 2. The shock absorbing component 1 includes a mounting block fixedly mounted on the inside of the placement box. The mounting block is located below the shock absorbing plate. A rectangular groove is provided on the top of the mounting block. The rectangular groove passes through the mounting block. Two sliding grooves are provided on both sides of the front of the mounting block. The two sliding grooves pass through the mounting block. The bottom inner wall of the placement box and the side of the shock absorbing plate close to each other are elastically connected through a spring damping rod assembly 2. Moving blocks are slidably installed inside the two sliding grooves respectively.

[0007] Preferably, an air outlet is provided at the top of the air pump, an L-shaped groove is provided on the outer wall of the air outlet, a connecting hose is rotatably installed on the inner wall of the air outlet, a protrusion is fixedly installed on the outer wall of the connecting hose, and the protrusion is slidably connected to the L-shaped groove.

[0008] Preferably, the shock absorbing assembly 2 has two groups, including two upper fixed blocks fixedly installed on the bottom of the shock absorbing plate, and a round rod 1 is rotatably installed on one side of the two upper fixed blocks close to each other, and two connecting rods 1 are rotatably sleeved on the outer wall of the round rod 1, and the two connecting rods 1 are hinged to the outer wall of the corresponding moving block.

[0009] Preferably, the shock absorbing component 2 includes two lower fixed blocks fixedly mounted on the inner wall of the bottom of the placement box, and a round rod 2 is rotatably mounted on one side of the two lower fixed blocks close to each other, and two connecting rods 2 are rotatably sleeved on the outer wall of the round rod 2, and the two connecting rods 2 are hinged to the corresponding moving blocks.

[0010] Preferably, the two groups of shock absorbing components are symmetrically distributed with the spring damping rod assembly 2 as the symmetry axis.

[0011] Preferably, the two moving blocks are elastically connected to the sides of the sliding slot that are close to each other through a spring damping rod assembly.

[0012] Preferably, a protective sleeve is slidably mounted on the outer wall of the connected hose, and the protective sleeve is threadedly connected to the L-shaped groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention provides a sliding track for the moving block by setting a shock-absorbing component 1 through a rectangular groove and a sliding groove. The elastic connection of the spring damping rod assembly 2 further enhances the shock-absorbing effect, ensures the stable connection between the shock-absorbing plate and the placement box, and the moving blocks are slidably installed in the two sliding grooves, so that the moving block can move freely according to the shock-absorbing needs. During the inflation or movement process, when the air pump vibrates, the moving block will move accordingly and compress the spring damping rod assembly 2, thereby converting the vibration energy into elastic potential energy and storing it. When the vibration weakens, the spring damping rod assembly 2 will release the stored energy to reset the moving block, thereby completing a shock-absorbing cycle. By setting the shock-absorbing device, whether it is vehicle bumps, luggage squeezing during transportation, or natural vibrations during inflation, they can be effectively absorbed and alleviated, which not only improves the durability and service life of the air pump, but also ensures the stability of its inflation efficiency and air tightness, providing users with a safer and more reliable use experience.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 8 As shown, the present invention provides a manual air-powered vehicle inflator, comprising a placement box 1, a shock-absorbing plate 8 is slidably mounted inside the placement box 1, an air pump 2 is arranged on the top of the shock-absorbing plate 8, and a shock-absorbing mechanism is arranged on the bottom of the shock-absorbing plate 8;

[0026] The shock absorbing mechanism includes a shock absorbing component 1 and a shock absorbing component 2. The shock absorbing component 1 includes a mounting block 9 fixedly mounted on the inside of the placement box 1. The mounting block 9 is located below the shock absorbing plate 8. A rectangular groove 10 is provided on the top of the mounting block 9. The rectangular groove 10 passes through the mounting block 9. Two sliding grooves 11 are provided on both sides of the front of the mounting block 9. The two sliding grooves 11 pass through the mounting block 9. The bottom inner wall of the placement box 1 and the side of the shock absorbing plate 8 that are close to each other are elastically connected through a spring damping rod assembly 20. Moving blocks 18 are slidably installed inside the two sliding grooves 11 respectively.

[0027] By setting up the shock-absorbing component 1, a sliding track is provided for the moving block 18 through the rectangular groove 10 and the sliding groove 11. The shock-absorbing effect is further enhanced due to the elastic connection of the spring damping rod assembly 20, ensuring the stable connection between the shock-absorbing plate 8 and the placement box 1. The moving blocks 18 are slidably installed inside the two sliding grooves 11, so that the moving block 18 can move freely according to the shock-absorbing needs. During the inflation or movement process, when the air pump 2 generates vibration, the moving block 18 will move accordingly and compress the spring damping rod assembly 20, thereby converting the vibration energy into elastic potential energy and storing it. When the vibration weakens, the spring damping rod assembly 20 will release the stored energy to reset the moving block 18, thereby completing a shock-absorbing cycle.

[0028] like Figures 3 to 5 As shown, an air outlet 3 is provided at the top of the air pump 2, an L-shaped groove 4 is opened on the outer wall of the air outlet end 3, a connecting hose 5 is rotatably installed on the inner wall of the air outlet end 3, a protrusion 6 is fixedly installed on the outer wall of the connecting hose 5, and the protrusion 6 is slidably connected to the L-shaped groove 4.

[0029] The connecting hose 5 can rotate freely relative to the air outlet end 3, but the sliding connection between the protrusion 6 and the L-shaped groove 4 ensures that the hose will not accidentally fall off or loosen during the inflation process. The stable connection structure ensures the continuity and safety of inflation. The traditional fixed connection method may cause wear between the hose and the air outlet end during long-term use. The present device reduces direct contact and friction through a sliding connection, thereby extending the service life of the hose and the air outlet end.

[0030] like Figures 6 to 8 As shown, the shock absorbing assembly 2 has two groups, including two upper fixed blocks 12 fixedly installed at the bottom of the shock absorbing plate 8, and a round rod 13 is rotatably installed on one side of the two upper fixed blocks 12 close to each other, and two connecting rods 14 are rotatably sleeved on the outer walls of the round rod 13, and the two connecting rods 14 are hinged to the outer walls of the corresponding moving blocks 18.

[0031] Through the arrangement of two sets of shock-absorbing components, especially the articulation method of connecting rod 1 and the moving block, the inflatable device can more effectively disperse and absorb force when subjected to vibration or impact, thereby greatly reducing damage to the device itself. The multi-level shock-absorbing design significantly improves the stability and durability of the device.

[0032] like Figures 6 to 8 As shown, the shock absorbing assembly 2 includes two lower fixed blocks 15 fixedly mounted on the inner wall of the bottom of the placement box 1, and a round rod 2 16 is rotatably mounted on one side of the two lower fixed blocks 15 close to each other, and two connecting rods 2 17 are rotatably sleeved on the outer wall of the round rod 2 16, and the two connecting rods 2 17 are hinged to the corresponding moving blocks 18.

[0033] Through the ingenious combination of round rod two and connecting rod two, a movable shock-absorbing mechanism is formed. When the inflatable device vibrates during inflation or movement, it can absorb and disperse part of the vibration energy, thereby reducing the impact on the placement box and internal components, achieving a shock-absorbing effect.

[0034] like Figures 6 to 8 As shown, the two groups of shock absorbing components are symmetrically distributed with the spring damping rod assembly 20 as the symmetry axis.

[0035] The symmetrically distributed shock-absorbing components can more effectively disperse and absorb vibrations and impacts from different directions, allowing the inflatable device to maintain higher stability and balance during operation, reducing shaking and deviation caused by improper operation or external environmental factors.

[0036] like Figures 3 to 5 , Figures 6 to 8 As shown, the two moving blocks 18 are elastically connected to the side of the sliding groove 11 that is close to each other through a spring damping rod assembly 19, and a protective sleeve 7 is slidably installed on the outer wall of the connecting hose 5, and the protective sleeve 7 is threadedly connected to the L-shaped groove 4.

[0037] By setting the spring damping rod assembly 19, the two moving blocks 18 can maintain a stable relative position in the sliding groove 11, and can quickly return to the preset equilibrium state even when subjected to external force or vibration generated during the inflation process, effectively reducing device failure or performance degradation caused by vibration or unstable factors, thereby improving the durability of the inflation device and extending its service life. The protective cover 7 is set in a sliding installation manner, so that the user can easily slide the protective cover 7 along the hose to the desired position as needed, and the adjustment of the protective cover 7 can be completed without disassembling any parts. At the same time, the threaded connection design with the L-shaped groove 4 ensures the stability of the interface connecting the hose 5 and the air outlet 3 after installation, making it difficult to fall off, which is convenient for users to quickly install and disassemble, and ensures the stable performance of the inflation device during the inflation process.

[0038] The working principle and use process of the present invention:

[0039] First, open the placement box 1, align the connecting hose 5 with the pipe mouth of the air outlet end 3, and then rotate the connecting hose 5 so that the protrusion 6 slides along the L-shaped groove 4, so that the connecting hose 5 and the air outlet end 3 are initially fixed, and then slide the protective cover 7 so that the protective cover 7 is close to the air outlet end 3 and is threadedly connected to the air outlet end 3, so as to perform a secondary fixation on the connection, and then turn on the air pump 2 to perform the inflation operation for the power vehicle in and out. During the transportation of the device or when the air pump 2 vibrates in the working state, the shock absorbing plate 8 will vibrate accordingly, and the moving block 18 slides freely in the sliding groove 11 and compresses the spring damping rod assembly 20 to convert the vibration energy into elastic potential energy storage. The moving block 18 on the left is connected to the round rod 13 through the rotation of the connecting rod 14, and the moving block 18 on the right is connected to the round rod 16 through the rotation of the connecting rod 2 17, so as to form a multi-level shock absorbing system. The vibration or impact force is transmitted and dispersed through the connecting rod and the round rod, which greatly reduces the damage to the device itself.
