[0013] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0014] The most critical concept of the present invention is: through the cooperation between the secondary winding and the induction coil, the primary coil and the secondary coil, and the guide electromagnet and the secondary coil, wireless power supply of the image acquisition device is realized and the acquisition efficiency and acquisition speed of the image acquisition device are improved.

[0015] Please refer to Figure 1 , the technical solution provided by the present invention:

[0016] An image acquisition device based on wireless power supply, comprising a base, a guide rail, a support base and an image acquisition device;

[0017] The guide rail is arranged on the base, the support seat is arranged above the guide rail and a receiving cavity for receiving the guide rail is arranged at the lower part of the support seat, and the image acquisition device is arranged on the support seat;

[0018] An induction coil and a secondary coil are provided on the guide rail, and a secondary winding, a guide electromagnet and a primary coil are provided on the inner surface of the side wall where the accommodating cavity is located. A mutual repulsive force is generated between the secondary winding and the induction coil so that the support base is suspended above the guide rail. The guide electromagnet and the secondary coil are correspondingly arranged to enable the support base to move along the extension direction of the guide rail. The primary coil and the secondary coil are correspondingly arranged to provide power for the support base to move along the extension direction of the guide rail.

[0019] From the above description, it can be seen that the beneficial effects of the present invention are:

[0020] By setting an induction coil on the guide rail and generating a repulsive force between the secondary winding on the inner surface of the side wall of the accommodating cavity, the support seat can be suspended above the guide rail, and the secondary winding can supply power to the image acquisition device; the primary coil and the secondary coil are set correspondingly, which can provide power and braking guarantee for the movement of the support seat, so that the support seat can move along the extension direction of the guide rail; the guide electromagnet and the secondary coil are set correspondingly, which can provide power for the support seat to move along the extension direction of the guide rail, and ensure that when the support seat deviates to the left or right, the guide electromagnet and the secondary coil interact with each other to generate a repulsive force, so that the support seat returns to its normal position; the image acquisition device based on wireless power supply designed in this scheme cooperates with the secondary winding and the induction coil, the primary coil and the secondary coil, and the guide electromagnet and the secondary coil, thereby realizing wireless power supply of the image acquisition device and improving the acquisition efficiency and acquisition speed of the image acquisition device, and the stroke of the image acquisition setting can be wirelessly extended.

[0021] Furthermore, the accommodating cavity is surrounded by side walls extending in a vertical direction and edges located on free ends of the side walls, respectively, provided at opposite ends of the bottom surface of the supporting seat;

[0022] A guide electromagnet is provided on the inner surface of each of the side walls extending in the vertical direction;

[0023] A primary coil is disposed on the inner surface of each edge located at the free end of the side wall.

[0024] From the above description, it can be seen that by providing a primary coil on the inner surface of the edge at each free end of the side wall, the balance of the support base can be ensured to enable it to move stably when the mutual repulsion force between the primary coil and the secondary coil is too large.

[0025] Furthermore, the edge located on the free end of the side wall is perpendicular to the side wall.

[0026] It can be seen from the above description that the support base can be made more stable during the movement.

[0027] Furthermore, the secondary winding is arranged on the bottom surface of the support seat and is arranged opposite to the induction coil integrated inside the guide rail.

[0028] It can be seen from the above description that it is possible to ensure that a mutual repulsive force is generated between the secondary winding and the induction coil inside the guide rail so that the support base can be suspended above the guide rail.

[0029] Furthermore, the plurality of induction coils are arranged in sequence along the central axis of the guide rail, and the induction areas of two adjacent induction coils are connected to each other.

[0030] From the above description, it can be seen that multiple induction coils are arranged in sequence along the central axis of the guide rail, which can ensure that the support base moves along the extension direction of the guide rail. The induction areas of two adjacent induction coils are connected to each other to generate magnetic force, thereby avoiding the support base affecting the operation of the image acquisition device due to poor contact between the induction areas of two adjacent induction coils during movement.

[0031] Furthermore, the secondary winding is arranged directly above the guide rail.

[0032] From the above description, it can be seen that the secondary winding is arranged directly above the guide rail, which can make the mutual repulsion between the secondary winding and the induction coil more stable, so that the support base can be stably suspended above the guide rail during movement.

[0033] Furthermore, the base includes a support arm, a first baffle, a second baffle and a bottom connecting member, the first baffle is fixedly set at one end of the bottom connecting member, the second baffle is fixedly set at the other end of the bottom connecting member, the support arm is fixedly set at the center position of the bottom connecting member, the first baffle, the second baffle and the support arm are parallel to each other, and the first baffle and the second baffle are both made of metal.

[0034] It can be seen from the above description that by providing the first baffle and the second baffle made of metal material, it is possible to prevent the image acquisition device from being disturbed by external magnetic force when working, which is beneficial to the stability of the operation of the image acquisition device.

[0046] The plurality of induction coils are arranged in sequence along the central axis of the guide rail 2, and the induction areas of two adjacent induction coils are connected to each other.
