Description

Technical Field

[0001] The utility model relates to the technical field of wall climbing toys, in particular to an adsorption type wall climbing toy. Background Art

[0002] There are many types of toy cars on the market. Recently, wall-climbing toys that can be adsorbed on walls or inverted on ceilings have appeared. Such wall-climbing toys all rely on relative vacuum, that is, gas is extracted from the relatively sealed part between the wall-climbing toy and the wall, so that the outside atmospheric pressure is greater than the atmospheric pressure of the relatively sealed part between the wall-climbing toy and the wall. The atmospheric pressure outside the wall-climbing toy presses the wall-climbing toy against the wall, which requires a relatively airtight space to be formed around the relatively sealed body of the wall-climbing toy. However, most existing wall-climbing toys adopt a structural design of a central air duct straight through or a trumpet-shaped air duct to extract air. This method easily leads to low negative pressure and unstable adsorption, causing the wall-climbing toy to fall. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 As shown, a suction-type wall-climbing toy includes a toy body 1, a suction mechanism 2, a front drive mechanism 3, and a rear drive mechanism 3a. In this embodiment, the toy body 1 is composed of a shell 11, a chassis, a head 12, a tail 13, forelimbs 14, and hind limbs 15. The forelimbs 14 are a pair connected and hinged to the front end of the shell 11, the head 12 is hinged between the forelimbs 14 and the head end of the shell 11, the hind limbs 15 are a pair connected and hinged to the rear end of the shell 11, and the tail 13 is hinged between the hind limbs 15 and the rear end of the shell 11. The suction mechanism 2 is arranged on the chassis of the toy body 1, and is used to make the toy body 1 adsorb on the wall. The front drive mechanism 3 is arranged on one side of the front end of the suction mechanism 2, and the rear drive mechanism 3a is arranged on the other side of the rear end of the suction mechanism 2 relative to the front drive mechanism 3, and is used to drive the toy body 1 to move.

[0025] Reference Figure 2-Figure 4 As shown, the adsorption mechanism 2 includes an impeller 23, a rotation drive device 24, and a vacuum chamber 25. The vacuum chamber 25 is arranged on the chassis. In this embodiment, the vacuum chamber 25 is composed of an upper shell 21 and a lower shell 22. The lower shell 22 is fixedly connected to the chassis, and the upper shell 21 is covered on the lower shell 22 to form a closed space between the upper shell 21 and the lower shell 22. The bottom surface of the vacuum chamber 25 is provided with a first adsorption hole 221 and a second adsorption hole 222 that are connected to each other, and the top surface of the vacuum chamber 25 is provided with an air outlet channel 27 that is connected to each other, wherein the first adsorption hole 221 and the second adsorption hole 222 are arranged on the lower shell 22, and the air outlet channel 27 is arranged on the upper shell 21. A mounting frame 26 is mounted on the top surface of the vacuum chamber 25, and the impeller 23 is rotatably arranged at the bottom of the mounting frame 26, so that the impeller 23 is rotatably arranged above the air outlet channel 27, and the rotation drive device 24 is fixedly installed on the mounting frame 26.

[0026] This embodiment further includes a power module, which is disposed in the toy body 1 , and the rotation driving device 24 is electrically connected to the power module, so that the power module is used to provide power for the rotation driving device 24 .

[0027] Combination Figure 5 As shown, further, the air outlet channel 27 includes a guide portion 271 inclined toward the inside of the vacuum chamber 25 to form a trumpet-shaped portion that is larger at the top and smaller at the bottom, and a through hole 272 arranged at the center of the guide portion 271. In this embodiment, the guide portion 271 and the upper shell 21 are integrally formed, and a plurality of arc-shaped blades 231 are equidistantly arranged on the bottom surface of the impeller 23 along the circumferential direction. An exhaust gap is formed between the impeller 23 and the guide portion 271. The impeller is driven to rotate by the rotary drive device 24. The arc-shaped blades 231 used in this embodiment can better conform to the natural flow path of the airflow, reduce leakage, and enable the impeller 23 to generate a larger negative pressure, thereby utilizing the first adsorption hole 221 and the second adsorption hole 222 to draw the air at the front and rear ends of the chassis into the vacuum chamber 25, and the air in the vacuum chamber 25 flows out from the exhaust gap driven by the impeller 23, so that negative pressure is generated between the chassis of the toy body 1 and the wall.

[0028] Among them, the outer end height of the arc blade 231 is smaller than the inner end height of the arc blade 231, so that the impeller 23 and the arc blade 231 are overall cone-shaped, so that the shape of the impeller 23 matches the shape of the air outlet channel 27. Compared with the traditional straight air duct or the trumpet-shaped air duct that gradually increases from top to bottom, this embodiment not only reduces the gap of the exhaust gap, making its air duct smaller, but also reduces the external air flow back into the vacuum chamber, so that the air flow pressure is increased, thereby greatly increasing the suction of the vacuum chamber, and the negative pressure generated is more uniform, the toy body 1 can be better adsorbed on the wall, ensuring that the toy body is not easy to fall off during the movement of the wall.

[0029] In another embodiment, the impeller is provided with a plurality of straight blades equidistantly along the circumferential direction, so as not to be limited to one shape of arc-shaped blades.

[0030] In another embodiment, the air outlet channel 27 includes a guide portion arranged in a plane on the vacuum chamber 25 and a through hole arranged at the center of the guide portion. In this embodiment, the guide portion and the upper shell are integrally formed. In order to ensure that the shape of the impeller matches the shape of the guide portion, the outer end height of the arc blade / straight blade in this embodiment is the same as the inner end height of the arc blade / straight blade, thereby reducing the gap of the exhaust gap between the impeller and the guide portion, thereby reducing the backflow of external air into the vacuum chamber, and increasing the negative pressure in the vacuum chamber.

[0031] A sealing component is provided on the periphery of the bottom surface of the vacuum chamber 25, and the sealing component includes a soft belt. The soft belt is composed of four pieces and is arranged around the bottom peripheral wall of the lower shell. In this embodiment, the sealing sheet is preferably made of soft material. When the toy body 1 is adsorbed on the wall, the soft belt on the vacuum chamber 25 contacts the wall, thereby reducing air leakage under the chassis, making the adsorption capacity of the toy body more stable and the movement smoother.

[0032] Reference Figure 1 Furthermore, a hollow mesh 213 is provided on the first adsorption hole 221 and the second adsorption hole 222 to prevent foreign matter from entering the vacuum chamber 25 under adsorption, thereby preventing blockage that affects the vacuum chamber's ability to adsorb normally.

[0033] Reference Figure 1 , Figure 2 As shown, the front driving mechanism 3 and the rear driving mechanism 3a both include a gear box 31 and a wheel 32. The gear box 31 is fixedly installed between the upper shell 21 and the chassis, and the wheel 32 is fixedly connected to the output shaft of the gear box 31. In this embodiment, the gear box 31 is composed of a worm gear, a worm, and a motor, so that the wheel 32 is driven to rotate through the gear box 31 to drive the toy body 1 to travel on the wall. When the wheel 32 of the front driving mechanism 3 or the rear driving mechanism 3a stops rotating, the toy body can automatically turn.

[0034] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
