Description

Technical Field

[0001] The utility model relates to the technical field of photographing devices, in particular to a convenient selfie camera. Background Art

[0002] In the existing shooting devices, two solutions are usually adopted to realize the main shooting and Selfie. The first solution is to set a rear camera for the main shooting and a front camera for the Selfie, such as a panoramic camera dual-lens installation structure disclosed in the Chinese utility model with publication number CN208924290U, which has a front lens and a rear lens. The second solution is to set the screen to be flippable and flip the screen 180 degrees when taking a selfie, so that the screen can observe the picture when taking a selfie, such as a selfie camera disclosed in the Chinese utility model with publication number CN2674481Y. When the display screen is flipped 180°, the camera can clearly see its position and status in the image through the flipped viewfinder display screen when taking a selfie, so that the selfie can be completed without the help of outsiders.

[0003] However, the above two solutions have the following shortcomings: the dual lenses of the first solution are expensive, and the low pixel of the front camera leads to unclear images and poor selfie effects. The second solution takes up a lot of space when the display screen is flipped. Utility Model Content

[0004] The purpose of the utility model is to provide a convenient selfie camera to address the deficiencies of the prior art, aiming to avoid the high-cost selfie function and not taking up space.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: a convenient selfie camera, comprising:

[0008] A first screen is disposed on a side of the camera body away from the lens; and

[0009] The second screen can be flipped and connected to a side of the camera body adjacent to a side where the lens is arranged and / or a side of the first screen. Specifically, when the second screen is flipped 90 degrees and erected, the image of the second screen faces the direction of the lens, so that the second screen can be seen even when facing the lens when taking a selfie.

[0010] As a further solution of the utility model: the convenient selfie camera also includes a flip cover, which can be flipped and connected to the side of the camera body adjacent to the side where the lens is provided and / or the side where the first screen is provided, and the second screen is provided on the flip cover.

[0012] As a further solution of the utility model: the flip structure includes a mounting seat with connecting ports on both sides, and the inner wall of the connecting port is provided with an arc-shaped limiting groove; the flip cover is provided with a movable connecting shaft inserted into the connecting port, and the movable connecting shaft is provided with a limiting protrusion matching the arc-shaped limiting groove.

[0013] As a further solution of the utility model: the flip structure is a torque hinge.

[0014] As a further solution of the utility model: the flip cover is provided with a accommodating cavity, and the convenient selfie camera also includes a screen control component matched with the second screen and installed in the accommodating cavity, and the second screen is installed on a side of the flip cover away from the bottom of the installation storage groove.

[0015] As a further solution of the utility model: the mounting seat includes a lower seat and an upper cover, the lower seat is provided with a slot and an alignment port, the upper cover is provided with an insertion strip matching the slot and an insertion column matching the alignment port, the arc-shaped limit grooves are respectively provided at both ends of the lower seat, and the arc of the arc-shaped limit groove is 90 degrees.

[0016] As a further solution of the utility model: a handle bevel is provided on a side of the installation storage groove away from the flip structure, and the flip cover is provided with a thin bevel matching the handle bevel.

[0017] As a further solution of the utility model: the flip cover is also provided with a glass cover plate and an inner lining gasket, and the second screen is sandwiched between the glass cover plate and the inner lining gasket.

[0018] As a further solution of the utility model: the flip cover is further provided with a rear cover plate, the rear cover plate is buckled on a side of the flip cover away from the second screen and sealed to form the accommodating cavity, the flip cover is provided with a clamping convex portion located inside the accommodating cavity, and the rear cover plate is provided with a clamping portion clamped by the clamping convex portion;

[0019] The flip cover is also formed with a connecting avoidance groove, and the movable connecting shaft is arranged on the inner side wall of the connecting avoidance groove. The movable connecting shaft includes a first half shaft arranged on the flip cover and a second half shaft arranged on the rear cover plate. When the convex portion is clamped on the buckling portion, the second half shaft presses against the first half shaft and forms the movable connecting shaft.

[0020] Beneficial effects of the utility model:

[0021] By setting up two screens, the first screen is used as the main screen (large screen), and the second screen is used as the secondary screen (small screen). The second screen can be flipped. When shooting the main camera, the second screen is perpendicular to the first screen, and the image of the second screen faces outside the camera body. The main camera can be shot by observing the first screen. When taking selfies, flip the second screen 90 degrees and stand it up. The second screen is parallel to the first screen, and the image of the second screen faces the direction of the lens. The selfie can be completed by observing the image of the second screen.

[0022] This solution, by adding a small-sized second screen, realizes that one lens completes the main camera and selfie functions. Compared with the first solution of the prior art, the production cost is low, and the selfie and main camera are both shot with the same lens, with high pixels, clear pictures, and good selfie effects. Compared with the second solution of the prior art, the second screen takes up less space when flipped, and when the second screen stands up after flipping, it will not protrude too much from the camera body, the flipping degree is small, and it is easy to operate; in addition, when the camera is placed on the camera stand for shooting, this solution can view the picture on both sides at the same time, that is, one side of the lens can view the picture of the second screen, and the other side of the lens can view the picture of the first screen. This is particularly important when adjusting the shooting angle and framing on the camera stand, and when multiple people collaborate to shoot. The second solution of the prior art can only view one display screen, which is not very applicable and inconvenient to use. It is also worth mentioning that in the second solution of the prior art, if you want to take pictures of low objects such as children, you need to flip the display screen 90 degrees (see paragraph

[0011] of its original specification) so that the display screen image faces upward and is perpendicular to the direction of the lens; while in the present solution, the image of the second screen in normal state is facing upward and perpendicular to the lens, and there is no need to flip it separately to achieve shooting of low objects, which is more convenient and practical.

[0023] It should also be added that the setting of the second screen enables the fill light function when shooting. Specifically, when the brightness of the scene in front of the lens is not enough, the second screen can be flipped up and displayed white light when the shutter is pressed, thereby filling the light for the scene in front of the lens. After shooting, the second screen returns to display the image of the lens without affecting the observation of the image. The fill light function can be used for both Selfie and main camera.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0050] like Figure 1 to Figure 9 As shown, in an embodiment of the utility model, a convenient selfie camera is provided, comprising: a camera body 1, a lens 2, a first screen 3 and a second screen 4; wherein:

[0051] A lens 2, arranged on one side of the camera body 1;

[0052] A first screen 3, arranged on a side of the camera body 1 away from the lens 2;

[0053] The second screen 4 can be flipped and connected to a side of the camera body 1 adjacent to a side where the lens 2 is provided and / or a side of the first screen 3. Specifically, when the second screen 4 is flipped and erected by 90 degrees, the screen of the second screen 4 faces the direction of the lens 2, so that the second screen 4 can be seen even when facing the lens 2 when taking a selfie.

[0054] In this solution, two screens are set up, the first screen 3 is used as the main screen (large screen), and the second screen 4 is used as the secondary screen (small screen), and the second screen 4 can be flipped. When the main camera is taken, the second screen 4 is perpendicular to the first screen 3, and the screen of the second screen 4 faces the outside of the camera body 1. The main camera can be taken by observing the first screen 3. When taking a selfie, the second screen 4 is flipped 90 degrees and erected, and the second screen 4 is parallel to the first screen 3, and the screen of the second screen 4 faces the direction of the lens 2. The selfie can be completed by observing the screen of the second screen 4.

[0055] By adding a small-sized second screen 4, the main camera and selfie functions can be completed by one lens 2. Compared with the first solution of the prior art, the production cost is low, and the selfie and main camera are both the same lens 2, with high pixels, clear pictures, and good selfie effects. Compared with the second solution of the prior art, the second screen 4 takes up less space when flipped, and when the second screen 4 stands up after flipping, it will not protrude too much from the camera body 1, the flipping degree is small, and it is easy to operate; in addition, when the camera is placed on the camera stand for shooting, this solution can watch the picture on both sides at the same time, that is, one side of the lens 2 can watch the picture of the second screen 4, and the other side of the lens 2 can watch the picture of the first screen 3. This is particularly important when adjusting the shooting angle and framing on the camera stand, and when multiple people collaborate to shoot. The second solution of the prior art can only watch one display screen, which is not very applicable and inconvenient to use. It is also worth mentioning that in the second solution of the prior art, if you want to take pictures of low objects such as children, you need to flip the display screen 90 degrees (see paragraph

[0011] of its original specification) so that the screen image faces upward and is perpendicular to the direction of the lens 2; while in this solution, the image of the second screen 4 in normal state is facing upward and perpendicular to the lens 2, and there is no need to flip it separately to achieve shooting of low objects, which is more convenient and practical.

[0056] It should also be added that the setting of the second screen 4 enables a fill light function to be realized during shooting. Specifically, when the brightness of the scene in front of the lens 2 is not enough, the second screen 4 can be flipped and stood up, and when the shutter is pressed, the second screen 4 displays white light, thereby providing fill light for the scene in front of the lens 2. After shooting, the second screen 4 returns to display the image of the lens 2, which does not affect the observation of the image. The fill light function can be used for both Selfie and main camera shooting.

[0057] In one embodiment, the convenient selfie camera further includes a flip cover 5, which is flippably connected to a side of the camera body 1 adjacent to a side where the lens 2 and / or the first screen 3 are disposed, and the second screen 4 is disposed on the flip cover 5. Specifically, the second screen 4 is flipped by flipping the flip cover 5.

[0058] In another embodiment, Figure 2~Figure 4As shown, the camera body 1 is provided with an installation storage slot 11, and the installation storage slot 11 is provided on a side of the camera body 1 adjacent to a side where the lens 2 and / or the first screen 3 are provided, and a flip structure 6 is provided on a side of the installation storage slot 11 close to the lens 2, and the flip cover 5 is movably connected to the flip structure 6. Specifically, the flip cover 5 can be stored, further avoiding occupying space, and the overall appearance is beautiful. Optionally, the width of the second screen 4 is smaller than the width of the camera body 1, and the length of the second screen 4 is smaller than the length of the installation storage slot 11, and the small screen can further reduce the occupied space and reduce the cost.

[0059] In yet another embodiment, Figure 3 , Figure 5~Figure 9 As shown, the flip structure 6 includes a mounting seat 61 with connecting ports 611 on both sides, and the inner wall of the connecting port 611 is provided with an arc-shaped limiting groove 612; the flip cover 5 is provided with a movable connecting shaft 51 inserted into the connecting port 611, and the movable connecting shaft 51 is provided with a limiting protrusion 52 matching the arc-shaped limiting groove 612. Optionally, the movable connecting shaft 51 is slightly tightly connected to the connecting port 611 to ensure that the flip cover 5 can maintain a certain pre-tightening force when it is normally stored or flipped or erected, thereby avoiding the adverse effects caused by the looseness and instability of the flip cover 5. Optionally, by setting a certain draft angle on the movable connecting shaft 51 and inserting it into the connecting port 611, the movable connecting shaft 51 has a certain pre-tightening force, and can also flip and rotate without getting stuck when a thrust is applied, further avoiding the adverse effects caused by the looseness and instability of the flip cover 5. Optionally, the bottom of the installation storage groove 11 is provided with a first magnet that smoothly transitions with the bottom of the groove, and one side of the flip cover 5 is provided with a second magnet that smoothly transitions with the surface and matches the first magnet. When the flip cover 5 is stored, the first magnet and the second magnet are attracted to prevent the flip cover 5 from accidentally flipping over when the camera body 1 is tilted or inverted. The flush transition of the magnets can avoid occupying space. The second magnet can be set on the rear cover 50.

[0060] In another embodiment, the flip structure 6 is a torque hinge (not shown). Specifically, the torque hinge can be a damping hinge or a self-resetting hinge. The torque hinge is used to achieve arbitrary stoppage of the flip cover 5. The working principle of the torque hinge is based on its special geometry and material properties. It is usually made of elastic material and has a specific geometry to provide bending and torsion elasticity in a specific direction. The torque hinge is a reversible torque regulator, and its principle is to apply the principle of damping oil viscosity change to structures such as doors and windows to achieve control of the opening and closing speed. When the structure is opened, the oil is compressed, resulting in an increase in torque, which hinders the opening speed of the structure; when the structure is closed, the oil is released, the torque is reduced, and the closing speed of the structure is slowed down. The torque hinge allows an object to rotate on an axis and provides precise torque control during the rotation process. The moving range of the torque hinge is between zero and one hundred and eighty degrees, and the closing angle can reach three hundred and sixty degrees, and the reciprocating torque within the movable range is constant and can be stopped at will. The concealment of the torque hinge is better. For example, the hidden torque hinge does not show any trace of the hinge after the door is closed, which is more beautiful. The screen and the body of the laptop are connected by an adjustable connection mechanism, which is a torque hinge, which is suitable for the flip cover 5 connection of this solution. The torque hinge allows the screen to rotate and fix freely within a certain angle range, so that the user can adjust the angle and position of the screen according to their needs. The torque hinge can provide stable rotational movement and provide precise torque control during rotation. This allows the user to easily open the screen to the desired angle and keep it in that position without additional support or fixation. The concealment of the torque hinge is better. In laptops, it is usually designed to be relatively small and hidden in the connection between the screen and the body, which does not affect the aesthetics of the whole machine. Torque hinges are not only widely used in laptops, but also widely used in other electronic devices that require precise control of angles and rotations, such as tablets, smart phones, monitors, etc. Therefore, the flip structure 6 adopts a torque hinge, and this connection method provides users with a flexible and stable second screen 4 angle adjustment experience.

[0061] In another embodiment, if Figure 7 As shown, the flip cover 5 is provided with a receiving cavity 53, and the convenient selfie camera further includes a screen control component matched with the second screen 4 and installed in the receiving cavity 53, and the second screen 4 is installed on a side of the flip cover 5 away from the bottom of the installation receiving groove 11. Specifically, the structure is compact and the configuration is reasonable, which further reduces the occupied space and improves the overall aesthetics.

[0062] In another embodiment, if Figure 5 and Figure 6As shown, the mounting seat 61 includes a lower seat 613 and an upper cover 614, the lower seat 613 is provided with a slot 631 and an alignment port 632, the upper cover 614 is provided with an insertion strip 641 matching the slot 631 and an insertion column 642 matching the alignment port 632, the arc-shaped limiting groove 612 is respectively provided at both ends of the lower seat 613, and the arc of the arc-shaped limiting groove 612 is 90 degrees. Specifically, the arc-shaped limiting groove 612 is composed of a 1 / 4 arc, so that the limiting protrusion 52 is limited in the arc-shaped limiting groove 612, and then the flip cover 5 is limited and flipped 90 degrees, that is, the optimal flip angle for predetermined Selfie.

[0063] In another embodiment, if Figure 2 As shown, the side of the installation storage slot 11 away from the flip structure 6 is provided with a hand inclined surface 111, and the flip cover 5 is provided with a thin inclined surface 54 matching the hand inclined surface 111. Specifically, the thin inclined surface 54 makes one end of the flip cover 5 thinner, so that it is easier to grasp the flip cover 5, and the matching arrangement with the hand inclined surface 111 makes it easier to turn the flip cover 5.

[0064] In another embodiment, if Figure 4 As shown, the flip cover 5 is further provided with a glass cover plate 55 and an inner lining gasket 56, and the second screen 4 is sandwiched between the glass cover plate 55 and the inner lining gasket 56. Specifically, the structure is compact and the configuration is reasonable, which further reduces the occupied space and improves the overall aesthetics.

[0065] Another embodiment, such as Figure 5~Figure 9 As shown, the flip cover 5 is also provided with a rear cover plate 50, and the rear cover plate 50 is buckled on the side of the flip cover 5 away from the second screen 4 and sealed to form the accommodating cavity 53, and the flip cover 5 is provided with a clamping protrusion 57 located inside the accommodating cavity 53, and the rear cover plate 50 is provided with a clamping portion 501 clamped by the clamping protrusion 57; specifically, it is easy to assemble.

[0066] The flip cover 5 is also formed with a connection avoidance groove 58, and the movable connection shaft 51 is arranged on the inner side wall of the connection avoidance groove 58. The movable connection shaft 51 includes a first semi-shaft 511 arranged on the flip cover 5 and a second semi-shaft 512 arranged on the rear cover plate 50. When the clamping protrusion 57 is clamped on the buckling part 501, the second semi-shaft 512 abuts against the first semi-shaft 511 and forms the movable connection shaft 51. Specifically, the structure is compact and the configuration is reasonable, which further reduces the occupied space and improves the overall aesthetics.
