[0019] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand

[0020] Understood, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, the present utility model provides a remote control hand, including a driving hollow palm 1 and a remote control 2. Five swing fingers 3 are evenly arranged around the driving hollow palm 1. The remote control 2 is located on the left side of the driving hollow palm 1. A driving mechanism 11 is arranged at the rear side of the inner wall bottom of the driving hollow palm 1. A finger driving turntable 12 is movably installed at the front side of the inner wall bottom of the driving hollow palm 1. Embedded blocks 31 are fixedly installed at one ends of the five swing fingers 3 close to the driving hollow palm 1. The five embedded blocks 31 all penetrate into the inner cavity of the driving hollow palm 1. Rotating shafts 32 are fixedly installed on both sides of the five embedded blocks 31, and the rotating shafts 32 are movably connected with the inner cavity of the driving hollow palm 1. Extension rods 33 are fixedly installed at one ends of the five embedded blocks 31 far from the swing fingers 3. The five extension rods 33 are all located below the finger driving turntable 12. The five swing fingers 3 are all in an active relationship with the driving hollow palm 1, so as to facilitate free swinging.

[0022] As Figures 1-4As shown in the figure, a battery bottom cover 13 is provided at the bottom of the driving hollow palm 1. A battery compartment is provided at the top of the battery bottom cover 13. An auxiliary front wheel 14 is movably installed at the front side of the bottom of the driving hollow palm 1. The driving mechanism 11 includes a motor housing 111. The motor housing 111 is fixedly installed at the rear side of the inner wall bottom of the driving hollow palm 1. A driving motor 112 is fixedly installed at the bottom of the motor housing 111. A first gear 113 is fixedly installed on the output shaft of the driving motor 112. A second gear 114 is engaged with the outer wall of the first gear 113. A transmission shaft is fixedly installed through the center of the second gear 114. Moving main wheels 1141 are fixedly installed at both the left and right ends of the transmission shaft. Both of the two moving main wheels 1141 penetrate to the lower part of the driving hollow palm 1 and the bottom is on the same horizontal line as the bottom of the auxiliary front wheel 14.

[0023] The driving motor 112 is powered by the battery in the battery compartment. When the power is out, just remove the battery bottom cover 13 and replace it with a new battery. When in use, the driving hollow palm 1 can be controlled to move by using the remote control 2. When controlling, the driving motor 112 inside the motor housing 111 is started by using infrared rays, so as to drive the first gear 113 to rotate. When the first gear 113 rotates, the transmission shaft on both sides of the second gear 114 can be driven to rotate by using the engagement with the second gear 114, so as to drive the moving main wheels 1141 to rotate. The two moving main wheels 1141 cooperate with an auxiliary front wheel 14 to move smoothly.

[0024] As Figures 1-4 shown in the figure, a transmission gear 115 is engaged with the outer wall of the second gear 114. The right side of the transmission gear 115 is movably connected to the right side inner wall of the motor housing 111. A third gear 116 is fixedly installed at the center of the left side of the transmission gear 115. A second straight bevel gear 117 is engaged with the outer wall of the third gear 116. A transmission rod 118 is fixedly installed at the center of the front side of the second straight bevel gear 117. The transmission rod 118 penetrates to the front side of the motor housing 111 and a fourth gear 119 is fixedly installed. A first straight bevel gear 121 is fixedly installed at the center of the bottom of the finger driving turntable 12. A plurality of arc extrusion bumps 122 are annularly and arrayedly fixedly installed at the eccentric part of the bottom of the finger driving turntable 12. The tooth blocks on the outer wall of the fourth gear 119 are engaged with the tooth blocks at the bottom of the first straight bevel gear 121. Five extension rods 33 are respectively located between two adjacent ones of the plurality of arc extrusion bumps 122.

[0025] When the second gear 114 rotates, it can drive the third gear 116 to rotate by meshing with the transmission gear 115. Then, by meshing the third gear 116 with the second straight bevel gear 117, the second straight bevel gear 117 can be driven to rotate. The connection of the transmission rod 118 drives the fourth gear 119 to rotate. By cooperating with the meshing of the fourth gear 119 and the first straight bevel gear 121 at the bottom of the finger driving turntable 12, the overall finger driving turntable 12 can be driven to rotate rapidly while driving the hollow driving palm 1 to move. By cooperating with the repeated extrusion of the arc-shaped extrusion bump 122 on the five extension rods 33, the five swinging fingers 3 can utilize the movable relationship between the two side rotating shafts 32 of the embedding block 31 and the hollow driving palm 1 to achieve rapid reciprocating up and down swinging. Thus, while the hollow driving palm 1 is moving, the five swinging fingers 3 can also swing, increasing the simulation effect.

[0026] Next, the working principle of this remote control hand will be specifically described.

[0027] As Figures 1-4 shown, when in use, the remote control 2 can be used to control the movement of the hollow driving palm 1. When controlling, the driving motor 112 inside the starting motor housing 111 is controlled to start by using infrared rays, thereby driving the first gear 113 to rotate. When the first gear 113 rotates, it can drive the transmission shafts on both sides of the second gear 114 to rotate by meshing with the second gear 114, thereby driving the moving main wheels 1141 to rotate. The two moving main wheels 1141 cooperate with an auxiliary front wheel 14 to achieve stable movement. When the second gear 114 rotates, it can drive the third gear 116 to rotate by meshing with the transmission gear 115. Then, by meshing the third gear 116 with the second straight bevel gear 117, the second straight bevel gear 117 can be driven to rotate. The connection of the transmission rod 118 drives the fourth gear 119 to rotate. By cooperating with the meshing of the fourth gear 119 and the first straight bevel gear 121 at the bottom of the finger driving turntable 12, the overall finger driving turntable 12 can be driven to rotate rapidly while driving the hollow driving palm 1 to move. By cooperating with the repeated extrusion of the arc-shaped extrusion bump 122 on the five extension rods 33, the five swinging fingers 3 can utilize the movable relationship between the two side rotating shafts 32 of the embedding block 31 and the hollow driving palm 1 to achieve rapid reciprocating up and down swinging. Thus, while the hollow driving palm 1 is moving, the five swinging fingers 3 can also swing, increasing the simulation effect. At the same time, the driving motor 112 is powered by the battery in the battery compartment. When it runs out of power, just remove the battery bottom cover 13 and replace it with a new battery.

[0028] In general, the above has described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, any modifications or improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention.
