Description

Technical Field

[0001] The utility model relates to camera manufacturing technology, in particular to a camera with a power supply protection function. Background Art

[0002] The multi-eye multi-directional camera includes multiple lenses, and the multiple lenses are distributed on the circumference of the multi-eye multi-directional camera to realize multi-directional monitoring. Among them, each lens of the adjustable multi-eye multi-directional camera can be independently adjusted in four axes, that is, each lens can be adjusted in the H direction (horizontal), V direction (vertical), R direction (rotation), and T direction (twist), thereby realizing multi-directional adjustment of the lens shooting angle. Multiple lenses and multiple directions can realize multi-directional and multi-scene monitoring, and realize the purpose of one camera replacing multiple independent cameras.

[0003] The existing multi-eye multi-directional camera includes a base part for installing and fixing the camera in a working environment and a lens part including a plurality of lenses. The base part and the lens part are two independent parts before installation. During installation, the base part is first fixed in the working environment, such as fixed on the ceiling, and then the lens part and the base part are joined and fixed. Since the camera often faces a working environment in a dim scene, in order to ensure the clarity of the captured image, a fill light will be configured on the lens part. The power supply of the fill light is usually achieved as follows: an electrical connection terminal is provided on the base part, and the electrical connection terminal can be connected to a power source (such as an external power source or a power source provided by the camera), and a light board of the fill light is provided on the lens part. When the lens part and the base part are fixedly connected, the electrical connection terminal and the light board are in conductive contact, thereby realizing the power supply of the fill light. However, when the base and lens are installed, the electrical connection terminals are exposed. If the camera is installed while the power is on, the positive and negative poles of the electrical connection terminals may be mistakenly connected. For example, if a screwdriver accidentally touches the positive and negative poles of the electrical connection terminals, this will cause a short circuit in the device and may directly burn out the motherboard.

[0017] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0019] See also Figure 1-Figure 4 The present embodiment provides a camera with a power supply protection function, comprising a base part 1 and a lens part 2 arranged opposite to each other, and also comprising a housing 3. A lens (not shown in the figure) and a fill light 21 are arranged on the lens part 2. The fill light 21 is used to fill light for the lens. The base part 1 and the lens part 2 are two independent parts before installation, and are joined and fixed together during installation. The fill light 21 comprises a light board 22 arranged at one end of the lens part 2 facing the base part 1, and an electrical connection terminal 12 arranged opposite to the light board 22 is arranged at one end of the base part 1 facing the lens part 2. The electrical connection terminal 12 is arranged in a manner of protruding and exposed to the end face of one end of the base part 1 facing the lens part 2, and the electrical connection terminal 12 comprises a positive electrode and a negative electrode. The electrical connection terminal 12 can be connected to a power supply (such as an external power supply or a power supply of the camera itself). When the base part 1 and the lens part 2 are joined and fixed, the electrical connection terminal 12 and the light board 22 are in conductive contact to realize the power supply of the fill light 21.

[0020] The camera further includes a protection switch 13, which can connect or disconnect the electrical connection between the power supply and the electrical connection terminal 12. In this embodiment, the protection switch 13 is a normally open button switch, which is arranged on the base 1 and connected in series with the electrical connection terminal 12. When the base 1 has not yet been engaged with the lens unit 2, the protection switch 13 is in an off state, and even if the power is turned on, the electrical connection terminal 12 will not be connected to the power supply. The protection switch 13 includes a button protruding from an end surface of the base 1 facing the lens unit 2. When the base 1 and the lens unit 2 are engaged, the lens unit presses the button on the end surface 23 facing the base, so that the protection switch 13 is closed and the electrical connection between the power supply and the electrical connection terminal 12 is connected. Through the above arrangement, this embodiment ensures that the electrical connection terminal 12 is connected to the power supply only after the base 1 and the lens unit 2 are engaged, thereby avoiding the short circuit problem caused by accidentally touching the electrical connection terminal 12.

[0021] In other embodiments, the protection switch 13 may also adopt other types of switches. For example, the protection switch may include a normally open reed switch provided on the base portion 1 and a magnet provided on the lens portion 2. The reed switch and the electrical connection terminal 12 are connected in series to connect or disconnect the electrical connection between the power supply and the electrical connection terminal 12. The magnet is configured to be able to approach the reed switch when the base portion 1 and the lens portion 2 are engaged, and the magnetic field of the magnet (Hall effect) causes the reed switch to close and the electrical connection between the power supply and the electrical connection terminal to be connected.

[0022] In this embodiment, the connection between the base 1 and the lens portion 2 is detachable. For example, the base 1 and the lens portion 2 are threadedly connected, and the angle of the lens on the lens portion 2 is adjustable, and the button of the protection switch 13 is resilient, so that the protection switch 13 can be reset to the disconnected position after the lens portion 2 and the base 1 are removed and separated. In this way, when the lens angle needs to be adjusted, once the lens portion 2 is removed, the protection switch 13 is automatically disconnected, the electrical connection terminal 12 is no longer energized, and the short circuit problem can also be avoided. Similarly, if the protection switch 13 adopts a reed switch, once the magnet is away from the reed switch, the reed switch can also be restored to the disconnected position. The reed switch belongs to the prior art, and its specific structure will not be repeated in this embodiment.

[0023] The camera of this embodiment is specifically a multi-eye and multi-directional camera, but it is obvious that the structure of the protection switch 13 can also be applied to other types of cameras that require power supply protection.

[0024] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes made to the present invention in form and detail, without departing from the spirit and scope of the present invention as defined in the appended claims, shall fall within the scope of protection of the present invention.
