[0026] Please also refer to Figures 1 to 5 This embodiment provides a mobile chassis of an inflatable toy, including an H-shaped shell 1, and a mobile component 2, a fan component 3 and a control component 4 respectively installed in the H-shaped shell 1. It can be understood that the mobile component 2 is used to perform operations such as straight movement, turning, and circling of the mobile chassis, the fan component 3 is used to achieve rapid inflation or deflation of the inflatable toy body, and the control component 4 is used to control the start and stop of the mobile component 2 and the fan component 3.

[0027] The H-shaped shell 1 includes a first shell 11 and a second shell 12. The first shell 11 is provided with a plurality of positioning holes 111 at intervals along the contour line, and the second shell 12 is provided with a plurality of connecting posts 121 at intervals along the contour line. The connecting posts 121 are fixed in a one-to-one correspondence with the positioning holes 111. The fixing method adopted in this embodiment is bolt fixing, which makes the structure of the H-shaped shell 1 more stable. Moreover, the main body of the inflatable toy (not shown in the figure) is fixed on the connecting posts 121, and the main body passes through the gap 101 between the first shell 11 and the second shell 12 and is exposed on the H-shaped shell 1. It can be understood that the main body of the inflatable toy can be firmly mounted on the H-shaped shell 1 through the connecting posts 121. At the same time, the provision of the connecting posts 121 is also conducive to the rapid installation of the main body, thereby improving the production and assembly efficiency.

[0028] In other embodiments, the positioning hole 111 and the connecting post 121 may also be fixed by other means, such as plug-in connection, welding, etc.

[0029] The central horizontal bar of the H-shaped housing 1 defines a fan cavity 100 for mounting the fan assembly 3. A first through-hole 110 is provided on the rear side of the fan cavity 100. When the body of an inflatable toy is connected to the H-shaped housing 1, the first through-hole 110 is located within the cavity enclosed by the body. The central horizontal bar also defines a plurality of second through-holes 120, which are arranged in rows and columns along the central horizontal bar and the bottom wall of the fan cavity 100. These second through-holes 120 are positioned on the ground-facing side of the H-shaped housing 1, allowing external air to enter the H-shaped housing 1 through the second through-holes 120.

[0030] In this embodiment, the walls of the fan chamber 100 are provided with a first recess 130 for securing the fan assembly 3 and a second recess 140 for securing the movable assembly 2. It will be appreciated that the first recesses 130 are disposed on opposite sides of the walls of the fan chamber 100, and the two first recesses 130 can have the same or different openings depending on the specific size and structure of the fan assembly 3. The second recesses 140 are also disposed on opposite sides of the walls of the fan chamber 100 to assist in securing the movable assembly 2, preventing it from easily moving out of its fixed position, thereby improving the structural stability of the movable chassis.

[0031] In other embodiments, the fan cavity 100 may also eliminate the first recess 130 and / or the second recess 140 according to design requirements.

[0032] Each of the two vertical bars of the H-shaped housing 1 is provided with a roller cavity 200 for mounting the movable assembly 2. The two roller cavities 200 are connected to the fan cavity 100 in a straight line or at an angle, which can make the distribution of the movable assembly 2 and the fan assembly 3 more compact and reasonable. Each roller cavity 200 includes a first cavity 210 and a second cavity 220. A through opening 211 is provided on the first cavity 210, and the through opening 211 is provided on the same side as the second through hole 120 on the ground side. The second cavity 220 is provided corresponding to the second recess 140 and is used to cooperate with the second recess 140 to fix the movable assembly 2.

[0033] It can be understood that each of the vertical bars includes a first section 10 and a second section 20 provided on both sides of the roller cavity 200, and the first section 10 and the second section 20 are connected at an obtuse angle. The first section 10 and the second section 20 provided at an obtuse angle can exhibit a swinging movement effect when the mobile chassis suddenly moves in the opposite direction, thereby improving the fun and playability of the game. In this embodiment, the angle between the first section 10 and the horizontal line is equal to the angle between the second section 20 and the horizontal line. A follower wheel 30 is provided at the end of each of the vertical bars, and the follower wheel 30 is provided on the same side as the through-port 211 to assist in movement, so that the mobile chassis can move smoothly on the plane regardless of whether it swings to the left or right.

[0034] In other embodiments, the angle between the first section 10 and the horizontal line may be different from the angle between the second section 20 and the horizontal line.

[0035] The moving assembly 2 includes a first motor 21 and a driving wheel 22, which are connected in a driving manner. The first motor 21 is fixed within the second cavity 220 and is also fixed to the second recess 140. The driving wheel 22 is rotatably connected to the first cavity 210 and is exposed on the H-shaped housing 1 through the opening 211. The driving wheel 22 can touch the ground simultaneously with the follower wheel 30 on either side. When the first motor 21 is activated, it can control the driving wheel 22 to rotate forward and reverse, thereby realizing the movement function of the mobile chassis.

[0036] It can be understood that the two first motors 21 can cooperate to control the mobile chassis to realize moving functions such as forward, backward, turning, and circling, so that the mobile operation of the mobile chassis is more autonomous and more playable.

[0037] The fan assembly 3 is provided with a gap between the second through hole 120 for better ventilation and heat dissipation. The fan assembly 3 includes a fan cover 31, a second motor 32 and an impeller 33. The fan cover 31 is fixed on the first recess 130, and an air guide cavity 311 is provided in the fan cover 31. The air outlet 312 of the air guide cavity 311 is connected to the first through hole 110. The second motor 32 is driven and connected to the impeller 33, and the second motor 32 is fixed in the fan cover 31, and the impeller 33 is rotatably connected in the air guide cavity 311. When the second motor 32 is started, it can drive the impeller 33 to rotate left and right. Under the guidance of the air guide cavity 311 and the first through hole 110, the impeller 33 rotates left and right to drive the gas into the body of the inflatable toy, or the gas in the body moves outward, thereby realizing the rapid inflation and deflation function.

[0038] The control assembly 4 includes a control circuit board 41, as well as a battery 42 and a speaker 43 electrically connected to the control circuit board 41. The control circuit board 41 is also electrically connected to the first motor 21 and the second motor 32 to control the start and stop of the first motor 21 and the second motor 32. In this embodiment, the control circuit board 41 and the battery 42 are fixed to one of the first sections 10, and the speaker 43 is fixed to the other first section 10. It will be understood that this arrangement allows the center of gravity of the mobile chassis to be distributed in the first section 10 of the H-shaped housing 1. When the mobile chassis is placed on a flat surface, the driven wheel 30 and the driving wheel 22 on the first section 10 can be kept in contact with the ground, ensuring continuous and stable movement of the mobile chassis.

[0039] In other embodiments, the components of the control assembly 4 may also be dispersedly disposed at other positions of the H-shaped housing 1 .

[0040] The mobile chassis provided in this embodiment is generally used as follows: the main body of the inflatable toy is inserted into the insertion post 121, and then the insertion post 121 and the positioning hole 111 are fixed to the H-shaped housing 1. At this time, the main body is covered by the second housing 12. By starting the second motor 32, the impeller 33 is driven to quickly inflate the main body, thereby allowing the inflatable toy to be played in its inflated form. By coordinating the starting, stopping, and turning of the two first motors 21, the inflatable toy can be driven to move, turn, rotate, and perform other operations. During this process, it can also be displayed as a swinging movement, making the game highly interesting and playable.
