Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to an external power supply device for photographic equipment. Background Art

[0002] With the improvement of living standards, photography has become an important part of people's lives, and the requirements for photography experience are getting higher and higher. However, the battery capacity inside the existing camera is limited, so external power supply devices have emerged to provide additional power for photographic equipment, thereby extending the single use time of photographic equipment.

[0003] However, the existing external power supply device is basically simply connected to the side of the camera, which will cause the external power supply device to hinder the normal grip during shooting. In addition, the location of the heat dissipation port of the existing external power supply device is also poor, causing the heat dissipation port to face the hand holding the camera, thereby affecting the user experience. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model provides an external power supply device for photographic equipment to solve the above problems.

[0005] The technical solution adopted by the utility model to solve the technical problem is: an external power supply device for photographic equipment, which is arranged at the rear side of the camera and is electrically connected to the power input terminal of the camera, and includes a battery compartment, a handle and a heat dissipation side hole;

[0006] The handle is arranged on the upper side of the battery compartment body so that the handle is connected to the handle of the camera;

[0007] The heat dissipation side hole is arranged on the battery compartment body, and the direction of the heat dissipation side hole avoids the handle.

[0008] It is worth noting that the heat dissipation side hole is arranged on the left side or the right side of the battery compartment body, and the heat dissipation side hole is oriented to be inclined downward from the inside to the outside.

[0009] Optionally, a cooling fan is provided on the front side of the battery compartment body close to the camera, an air inlet of the cooling fan faces the camera, and an air outlet of the cooling fan is connected to the cooling side hole.

[0010] Preferably, a receiving groove is provided on the side of the battery compartment body, and the front side of the receiving groove is an open structure to allow the screen of the camera to be flipped into the receiving groove.

[0011] Specifically, an upper limit member and a lower limit member are provided on the side of the battery compartment body, and the upper limit member and the lower limit member are arranged up and down to form the accommodating groove between the upper limit member and the lower limit member.

[0012] It is worth noting that a connecting screw hole is provided at one end of the handle facing the handle of the camera, and the connecting screw hole cooperates with the screw of the handle of the camera.

[0013] The beneficial effect of the utility model is that in the external power supply device for photographic equipment, a smooth grip is formed by docking the handle with the handle of the camera, and the user can hold the grip when using it. The entire structure of the external power supply device is located behind the camera device, which has little impact on the shooting operation and makes the camera more convenient and comfortable to carry. Because the heat dissipation side hole is oriented away from the handle, when the user holds it, the heat discharged from the heat dissipation side hole will not blow directly onto the user's hand, thereby improving the user experience.

[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1-4 As shown, an external power supply device for photographic equipment is arranged at the rear side of a camera 7 and electrically connected to a power input terminal of the camera 7, comprising a battery compartment body 1, a handle 2 and a heat dissipation side hole 3;

[0021] The handle 2 is disposed on the upper side of the battery compartment body 1 so that the handle 2 is connected to the handle 71 of the camera 7;

[0022] The heat dissipation side hole 3 is disposed on the battery compartment body 1 , and the heat dissipation side hole 3 is oriented away from the handle 2 .

[0023] In this embodiment, the battery compartment body 1 is provided with an inner cavity, the inner cavity is provided with a battery, and the heat dissipation side hole 3 is connected to the inner cavity. In this embodiment, the battery compartment body 1 is provided with a power socket 11, and the power socket 11 is electrically connected to the battery. After the power socket 11 is electrically connected to the power input terminal of the camera 7 through a wire, the battery in the battery compartment body 1 can be used to power the camera 7. In addition, the rear side of the battery compartment body 1 is provided with an expansion socket 6, and the expansion socket 6 includes a USB interface, an NPF interface, and a DC interface for communication connection with an external device.

[0024] In the external power supply device for photographic equipment, the handle 2 is connected to the handle 71 of the camera 7 to form a smooth grip, which the user can hold when using. The entire structure of the external power supply device is located behind the camera device, which has little impact on the shooting operation and makes the camera more convenient and comfortable to carry. Since the heat dissipation side hole 3 is oriented away from the handle 2, when the user holds it, the heat discharged from the heat dissipation side hole 3 will not blow directly onto the user's hand, thereby improving the user experience.

[0025] It is worth noting that the heat dissipation side hole 3 is arranged on the left side or right side of the battery compartment body 1, and the direction of the heat dissipation side hole 3 is tilted downward from the inside to the outside. In this way, the heat in the cavity of the battery compartment body 1 can be discharged downward from the left side or right side of the battery compartment body 1 through the heat dissipation side hole 3, thereby preventing the heat from being discharged to the position of the handle 2. Specifically, the heat in the cavity of the battery compartment body 1 is mainly generated by the battery. After the heat dissipation side hole 3 is provided, the heat generated by the battery can be discharged in time, thereby ensuring the safety of the battery.

[0026] Optionally, a cooling fan 4 is provided on the front side of the battery compartment body 1 near the camera 7, the air inlet of the cooling fan 4 faces the camera 7, and the air outlet of the cooling fan 4 is connected to the cooling side hole 3. By providing the cooling fan 4, the heat generated when the camera 7 is running can be discharged from the cooling side hole 3 after passing through the cooling fan 4, thereby preventing the temperature at the position where the battery compartment body 1 and the camera 7 are in contact from being too high.

[0027] Preferably, a receiving groove 5 is provided on the side of the battery compartment body 1, and the front side of the receiving groove 5 is an open structure so that the screen 72 of the camera 7 can be flipped into the receiving groove 5. When the external power supply device for photographic equipment is not installed, the screen 72 of the camera 7 will be attached to the rear end of the camera 7 when not in use, and the screen 72 can be flipped and facing the photographer when in use. When installing the external power supply device for photographic equipment, the screen 72 needs to be turned away from the rear end of the camera 7 to make room for the installation of the external power supply device for photographic equipment, and then the screen 72 can be flipped into the receiving groove 5, and the receiving groove 5 is used to protect the screen 72.

[0028] Specifically, an upper limiter 51 and a lower limiter 52 are provided on the side of the battery compartment body 1, and the upper limiter 51 and the lower limiter 52 are arranged up and down to form the receiving groove 5 between the upper limiter 51 and the lower limiter 52. The upper limiter 51 and the lower limiter 52 protrude outward relative to the side of the battery compartment body 1, so that a concave receiving groove 5 can be formed on the side of the battery compartment body 1. In this embodiment, the upper limiter 51 and the lower limiter 52 are both made of silicone material, which plays a role of buffer protection.

[0029] It is worth noting that a connecting screw hole 21 is provided at one end of the handle 2 facing the handle 71 of the camera 7, and the connecting screw hole 21 matches with a screw 73 of the handle 71 of the camera 7. After the handle 2 and the handle 71 are in contact, the screw 73 is locked into the screw hole to complete the fixation of the external power supply device and the camera 7.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
