[0002] A camera (CAMERA or WEBCAM), also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, and real-time monitoring.

[0003] The existing cameras have the following problems: 1. They have a relatively simple structure and function, limited shooting angle and narrow field of view, making it impossible to achieve all-round monitoring, and resulting in low success rate and measurement accuracy in target acquisition; 2. On rainy days, the lens surface will get wet, making the image captured by the camera blurry and affecting the shooting effect; 3. During the shooting process, under certain lighting angles, overexposure or white light will occur, often leading to poor shooting results; 4. They lack stability and are easily affected by strong winds and vibrations, which limits the flexibility of equipment installation and adjustment, and also makes later maintenance and parts replacement inconvenient. Utility Model Content

It includes two bullet cameras and one spherical camera, realizes 360-degree rotation and tilt functions, provides a full-range monitoring perspective, improves the success rate of target acquisition and measurement accuracy. In addition, the windshield wiper and lens retractable design ensure the shooting effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A three-lens camera with both pistol-type and dome-type cameras, comprising a gimbal, a first camera, a second camera, and a third camera.

[0007] The gimbal includes a gimbal housing, with a first camera connection end and a second camera connection end respectively located on the left and right sides of the gimbal housing, and a third camera connection end located on the top or bottom. The first camera is mounted on the first camera connection end, the second camera is mounted on the second camera connection end, and the third camera is mounted on the third camera connection end. Each of the three connection ends includes a fixed part and a rotating part. The fixed part is fixedly connected to the gimbal housing, and the rotating part is rotatably connected to the camera.

[0008] A pitch driven gear is installed inside the gimbal housing where the first camera connection is located. This pitch driven gear is connected to the second camera connection via a synchronous linkage shaft. A horizontal driven gear is installed inside the gimbal housing where the third camera connection is located. A pitch motor A and a horizontal motor are installed inside the gimbal housing. The output ends of the pitch motor A and the horizontal motor are respectively equipped with a pitch drive gear and a horizontal drive gear, which are connected to the pitch driven gear and the horizontal driven gear, respectively. When the pitch motor A operates, it drives the pitch drive gear and the pitch driven gear to rotate, causing the first camera connection and the first camera mounted on it to rotate. Simultaneously, under the action of the synchronous linkage shaft, the second camera connection and the second camera mounted on it rotate synchronously, thus achieving pitch direction adjustment for the first and second cameras. Similarly, the horizontal motor drives the horizontal drive gear and the horizontal driven gear to rotate, causing the third camera connection and the third camera mounted on it to rotate, thus achieving horizontal direction adjustment for the third camera.

[0009] The first camera includes a first housing and a first lens inside it. The front end of the first housing has a first lens positioning port, and the front end of the first lens is placed inside the first lens positioning port. The second camera has the same structure as the first camera. The third camera includes a base. One side of the base is connected to the third camera's connecting end, and the other side has a tilt bracket. A third housing is disposed within the opening of the tilt bracket. The front end of the third housing has a third lens positioning port, and a third lens is disposed inside the third housing with its front end placed inside the third lens positioning port.

[0010] Preferably, the first camera and the second camera are also equipped with a wiper assembly. A wiper extension is provided in the first housing above the first lens positioning port. The wiper assembly includes a wiper drive motor, a wiper linkage, an adapter block, and a wiper head. The movable end of the wiper drive motor is connected to the wiper linkage, and both are housed within the first housing. The adapter block is placed within the wiper extension and is connected to both the wiper linkage and the wiper head, forming an L-shape. The wiper head is located in front of the first lens and has a wiper blade groove containing a wiper blade. When rainwater and debris adhere to the lens surface, the wiper drive motor starts, causing the wiper linkage to rotate. The wiper blade then contacts and wipes the lens, removing the rainwater and debris.

[0011] Preferably, the wiper drive motor is provided with a fixing lug, and the wiper drive motor is fixed in the housing through the fixing lug. The front end of the wiper linkage is provided with a rotating connecting seat, and the wiper linkage is rotatably connected to the housing through the rotating connecting seat.

[0012] Preferably, the connection point between the adapter block and the wiper linkage, and the connection point between the adapter block and the wiper head are respectively provided with connection holes, and connection bolts or connection pins are provided in the connection holes.

[0013] Preferably, the first camera and the second camera are also provided with baffles. The top surface and the front and back of the outer side of the first housing are respectively provided with baffle mounting holes. The baffle is L-shaped and is fixed to the outer side of the first housing through the baffle mounting holes. The front end of the baffle protrudes from the front end of the housing and has the function of preventing rainwater from falling onto the housing and the lens.

[0014] Preferably, a boss is provided on the first housing where the baffle mounting hole is located on the front side, so that there is a certain gap between the baffle and the housing, and the baffle is higher in the front and lower in the back, so that the rainwater falling on it flows backward.

[0015] Preferably, the first camera and the second camera are bullet cameras.

[0016] Preferably, the third camera is a spherical camera. A pitch pivot is located on one outer wall of the third housing, and a pitch motor B is located on the other inner wall. The pitch pivot is rotatably connected to a pitch support, and the pitch motor shaft of the pitch motor B is anti-rotatingly connected to the pitch support. The operation of the pitch motor B allows the third housing to rotate, thereby adjusting the pitch direction of the third camera.

[0017] Preferably, a lens mounting bracket is provided on the rear side of the third lens, a lens drive motor is provided on the top of the lens mounting bracket, a drive gear is provided at the output end of the lens drive motor, a gear ring is provided on the front side of the lens mounting bracket to mesh with the drive gear, and several guide blocks are provided on the inner side of the gear ring. The outer wall of the third lens is provided with corresponding spiral guide grooves to accommodate the guide blocks. When the lens drive motor operates, it drives the drive gear to rotate, and the gear ring also rotates accordingly. The guide blocks move along the spiral guide grooves, causing the third lens to produce back-and-forth extension and rotational movements. This is suitable for polarizing lenses, i.e., lenses with internal polarizers.

[0018] Preferably, the lens mounting bracket is equipped with a heat sink structure, a heat sink is located at the rear of the lens mounting bracket, and a control circuit board is located on the top of the lens mounting bracket and / or the rear of the heat sink. The heat sink can be a fan, which, combined with the heat sink structure, provides good cooling and heat dissipation.

[0019] The advantages of this utility model are as follows: 1. It is a three-lens camera that includes two bullet cameras and one spherical camera, realizing 360-degree rotation and tilt functions, providing a full-range monitoring perspective, and improving the success rate of target acquisition and measurement accuracy; 2. The wiper can remove rainwater and debris from the surface of the camera lens, improving the image quality captured by the camera. In addition, the structure of the baffle can reduce the amount of rainwater falling on the housing, especially the lens, ensuring the shooting effect; 3. The lens can automatically extend, retract, and rotate to capture images from different angles of light, avoiding overexposure or white light in the image, and improving the image quality captured by the camera; 4. The camera has strong stability and can work normally under the influence of strong winds and vibrations. Adjusting and using the camera is more flexible, reducing the difficulty of maintenance and parts replacement. Attached Figure Description
