Description

Technical Field

[0001] The present invention relates to the technical field of camera sensing structures, and in particular to a front and rear camera sensing structure with angle positioning. Background Art

[0002] In existing technologies, children's printer cameras have a front-facing display screen. A top camera captures images or photos, which are then displayed on the screen. The front camera is used for forward-facing selfies, while the rear camera is used for rear-facing shots. A children's printer typically uses two cameras. Because camera modules are manufactured by optical companies and are relatively expensive, to save costs, current children's printers use only one camera. This camera is flipped 180 degrees forward and backward to capture both front and rear shots. When the camera is positioned at 0 degrees, it captures front shots; when it is flipped 180 degrees, it captures rear shots.

[0003] When the camera is facing forward, the image appears upright. However, when flipped back to shoot, the image appears upside down. To address this issue, commercially available printers incorporate a Hall effect sensor at the camera position and a magnet at the back of the printer. When the camera is flipped back and approaches the magnet, the Hall effect sensor senses it, and a program inverts the image, ensuring that the image appears upright even when shot from behind.

[0004] However, this existing technology has significant drawbacks: the sensor switch used has a short sensing range. When the camera is rotated to the rear but not within the sensing range, for example, it has flipped 160 degrees, the camera has actually flipped to the rear and can capture the image behind it, but the image will not be upright. In fact, when the camera is rotated to 90 degrees, it is at the intersection of the front and rear cameras. Therefore, a structure that solves this problem and provides angle positioning is needed.

[0005] Therefore, the existing field of camera sensing structure technology needs to be further improved. Summary of the Invention

[0006] The purpose of the present invention is to provide a front and rear camera sensing structure with angle positioning, which solves the problem that the image is in an inverted state when the camera is rotated to the back and has not yet reached the sensing range, and can also locate and unlock the angle.

[0007] In order to achieve the above object, the present invention adopts the following scheme:

[0008] A front and rear camera sensing structure with angle positioning includes a main unit, a flip camera assembly is provided on the main unit, a micro switch is provided on the main unit, an air avoidance arc groove is provided on the flip camera assembly, the micro switch is clamped in the air avoidance arc groove, and multiple one-way clamping holes are evenly distributed on each circumference outside the flip axis on both sides of the flip camera assembly. Two elastic positioning rods that can be inserted into corresponding one of the one-way clamping holes are symmetrically provided in the main unit, and a synchronous unlocking structure for unlocking the elastic positioning rods on both sides is provided in the main unit.

[0009] Furthermore, the flip camera assembly includes a camera groove arranged on the front surface of the host, and shaft holes are provided on both sides of the camera groove. A camera is rotatably installed in the camera groove, and a rotating shaft body is provided on the camera, and the rotating shaft body is rotatably installed in the shaft hole.

[0010] Furthermore, circular chamfers are provided at both ends of the air-avoiding arc-shaped groove.

[0011] Furthermore, the host includes a shell, a pressure plate is provided in the shell, and a light board is provided under the pressure plate.

[0012] Furthermore, the pressure plate is fixed to the bottom of the housing to press the rotating axis of the flip camera assembly; the light board is installed above the pressure plate, and the micro switch is electrically connected to the main board through a cable, and the micro switch on the light board extends into the air-avoiding arc groove.

[0013] Furthermore, when the flip camera assembly rotates to 90 degrees, the micro switch fits the end of the air-avoiding arc groove; when the rotation continues, the flip camera assembly presses down the micro switch, triggering the mainboard to control the display screen image to flip 180 degrees.

[0014] Furthermore, the one-way locking hole includes a hemispherical protrusion arranged on the side wall of the camera, and a positioning hole is provided at the center position of the hemispherical protrusion.

[0015] Furthermore, the elastic positioning rod includes a transverse sleeve arranged in the shell, a positioning shaft is movably arranged in the transverse sleeve, and an elastic structure is provided between the transverse sleeve and the positioning shaft.

[0016] Furthermore, the elastic structure includes a movable spring plate arranged on the upper cover of the positioning shaft, a fixing ring is arranged in the transverse shaft sleeve, and a spring body is arranged between the fixing ring and the movable spring plate.

[0017] Furthermore, the synchronous unlocking structure includes a vertical guide groove arranged in the middle of the shell, a vertical slider is movably arranged in the vertical guide groove, a first hinge seat is arranged on each side of the vertical slider, a second hinge seat is arranged on the vertical slider, and a connecting rod is hinged between the first hinge seat and the second hinge seat on the corresponding side.

[0018] In summary, the present invention has the following beneficial effects compared to the prior art:

[0019] This invention addresses shortcomings in existing camera sensing structures. Its structural arrangement offers the following advantages: By combining a microswitch with a curved arc-shaped slot, when the flip camera assembly is rotated to 90 degrees, the microswitch engages the end of the curved arc-shaped slot. Further rotation and depressing the microswitch precisely triggers the motherboard to control the display screen image to flip 180 degrees. This solves the existing problem of the camera remaining upside down even after it has flipped to the shooting position due to a short sensing distance. Unidirectional latching holes, evenly spaced around the outer circumference of the flip axis on both sides of the flip camera assembly, cooperate with bilaterally symmetrical elastic positioning rods within the main unit to achieve angular positioning during the flip process, ensuring stable operation of the camera at a specific angle and ensuring excellent shooting results. Simultaneous unlocking of the angle is also possible, making operation more convenient. Rounded chamfers at both ends of the curved arc-shaped slot reduce friction during the flipping process, ensuring smoother flipping of the camera assembly. Using a physical sensor microswitch instead of the existing Hall effect sensor and magnet combination reduces costs while maintaining sensing accuracy. The structure is relatively simple, making it easy to implement and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1-10 The present invention provides a front and rear camera sensing structure with angle positioning, including a host 1, a flip camera assembly 2 provided on the host 1, a micro switch 3 provided on the host 1, an air-avoiding arc groove 4 provided on the flip camera assembly 2, the micro switch 3 being clamped in the air-avoiding arc groove 4, a plurality of one-way clamping holes 5 are uniformly distributed on each circumference outside the flip axis on both sides of the flip camera assembly 2, two elastic positioning rods 6 that can be inserted into corresponding one of the one-way clamping holes 5 are symmetrically provided in the host 1, and a synchronous unlocking structure 7 for unlocking the elastic positioning rods 6 on both sides is provided in the host 1;

[0032] The flip camera assembly 2 on the main unit 1 rotates about its pivot axis, with a microswitch 3 snapping into place within the arc-shaped groove 4 of the flip camera assembly 2. As the camera assembly flips, the microswitch moves within the groove, triggering the sensor when it reaches a specific angle. Furthermore, one-way latching holes 5 on either side of the pivot axis engage with elastic positioning rods 6 to achieve angular positioning. A synchronous unlocking mechanism 7 simultaneously unlocks both elastic positioning rods, facilitating adjustment of the camera's position.

[0033] The flip camera assembly 2 of the present invention includes a camera groove 201 provided on the front surface of the host 1, with shaft holes 202 provided on both sides of the camera groove 201. A camera 203 is rotatably mounted in the camera groove 201, and a rotating shaft body 204 is provided on the camera 203, and the rotating shaft body 204 is rotatably mounted in the shaft hole 202. The flip camera assembly 2 on the host 1 can rotate around the flip axis, and the micro switch 3 is snapped into the air-avoiding arc groove 4 of the flip camera assembly 2. When the camera assembly flips, the micro switch moves in the air-avoiding arc groove and triggers the induction when it rotates to a specific angle. At the same time, the one-way snap holes 5 on the outside of the flip axis on both sides cooperate with the elastic positioning rod 6 to achieve angle positioning; the synchronous unlocking structure 7 can synchronously unlock the elastic positioning rods on both sides to facilitate adjustment of the camera position.

[0034] The circular chamfers 100 are provided at both ends of the air-avoiding arc groove 4 of the present invention; the circular chamfers 100 at both ends of the air-avoiding arc groove 4 can reduce the friction between the micro switch and the groove wall during flipping, avoid jamming, make the camera assembly flip more smoothly, and ensure the stability of the micro switch sensing.

[0035] The host 1 described in the present invention includes a shell 101, a pressure plate 102 is arranged in the shell 101, and a light board 103 is arranged under the pressure plate 102; the pressure plate 102 and the light board 103 are arranged in the host shell 101, and the pressure plate is fixed to the bottom of the shell to fix the rotating axis of the camera assembly; the light board is located above the pressure plate, and the micro switch thereon is electrically connected to the main board to realize the transmission of the sensing signal.

[0036] The pressure plate 102 of the present invention is fixed to the bottom of the housing 101, and is used to press the rotation axis of the flip camera assembly 2; the light board 103 is installed above the pressure plate 102, and the micro switch 3 is electrically connected to the main board through a cable, and the micro switch 3 on the light board 103 extends into the air-avoiding arc groove 4; the pressure plate 102 presses the rotation axis of the camera assembly to ensure its rotation stability; the micro switch on the light board 103 extends into the air-avoiding arc groove 4, and when the camera assembly flips, the micro switch is pressed down and triggered, and the signal is transmitted to the main board through the cable to control the flipping of the display screen image.

[0037] According to the present invention, when the flip camera assembly 2 is rotated to 90 degrees, the micro switch 3 is in contact with the end of the air avoidance arc groove 4; when the rotation continues, the flip camera assembly 2 presses down the micro switch 3, triggering the main board to control the display screen image to flip 180 degrees; when the camera assembly is rotated to 90 degrees, the micro switch 3 is in contact with the end of the air avoidance arc groove 4; when the rotation continues to exceed 90 degrees, the camera assembly presses down the micro switch, triggering the main board to control the display screen image to flip 180 degrees, thereby realizing the upright switching of the front and rear camera images.

[0038] The one-way locking hole 5 described in the present invention includes a hemispherical protrusion 501 arranged on the side wall of the camera 203, and a positioning hole 502 is provided at the center position of the hemispherical protrusion 501; the hemispherical protrusion 501 and the positioning hole 502 of the one-way locking hole 5 cooperate with the elastic positioning rod 6. When the camera assembly is rotated to a specific angle, the elastic positioning rod is inserted into the positioning hole to form a lock, thereby realizing angle positioning and preventing the camera assembly from shaking at will.

Through the elastic force of the elastic structure 603, the positioning shaft is inserted into or disengaged from the one-way locking hole 5, thereby realizing automatic positioning and unlocking.

[0041] The synchronous unlocking structure 7 described in the present invention includes a vertical guide groove 701 arranged in the middle of the shell 101, and a vertical slider 702 is movably arranged in the vertical guide groove 701, and a first hinge seat 703 is provided on each side of the vertical slider 702, and a second hinge seat 704 is provided on the vertical slider 702, and a connecting rod 705 is hinged between the first hinge seat 703 and the second hinge seat 704 on the corresponding side; in the synchronous unlocking structure 7, the vertical slider 702 moves up and down in the vertical guide groove 701, and the first hinge seat 703 and the second hinge seat 704 on both sides are connected by the connecting rod 705, pushing the elastic positioning rods 6 on both sides to retract synchronously, realizing simultaneous unlocking of the positioning on both sides, and facilitating the angle adjustment of the camera assembly.
