It should be pointed out that the camera pop-up mechanism adopts a composite sliding structure, which has the advantages of smoothness and stability, high guiding and limiting accuracy, and easy disassembly, replacement and maintenance compared with a simple sliding block sliding structure. However, it can be understood that, in other embodiments, the sliding assembly 20 can also be replaced by other sliding structures, such as a sliding structure in which a sliding groove cooperates with a sliding block.

The ejection assembly 30 is disposed on the mounting board 21 and located on one side of the camera 10 for ejecting the camera 10 and locking the camera 10 when the camera 10 is retracted. Specifically, the ejection assembly 30 includes a housing 31, a sliding block 32, a traction spring 33, a pull rod 34 and a limiting elastic piece 35.

Wherein, the housing 31 includes a bottom shell 311 provided on the mounting plate 21, and a shell cover 312 provided on the bottom shell 311. The bottom of the bottom shell 311 is provided with a receiving groove 3111, so A first protrusion 3112 protrudes outward from the bottom of the receiving groove 3111.

The slider 32 is provided in the housing 31 and can slide along the sliding direction of the camera 10, and the bottom of the slider 32 is provided with a second convex post 321, the second convex post 321 Passing through the bottom shell 311 and extending into the receiving groove 3111, the second protrusion 321 can pass on the bottom shell 311 to follow the sliding block 32 to move. A push portion 322 extends from one side of the slider 32, the push portion 322 passes through the bottom shell 311, and the push portion 322 can run on the bottom shell 311 to follow the When the slider 32 moves, the pushing portion 322 and the camera 10 are located on opposite sides of the substrate 221.

Wherein, the traction spring 33 is received in the receiving groove 3111, and is connected between the first convex post 3112 and the second convex post 321, so as to pull the slider toward the ejection direction of the camera 10 Block 32, and under the pulling of the traction spring 33, the pushing portion 322 abuts against the abutting block 223.

Preferably, the abutting portion where the pushing portion 322 abuts against the abutting block 223 is tapered, the end of the abutting block 223 is provided with a tapered notch 2231, and the abutting portion abuts against In the tapered notch 2231, a tapered position-limiting fit is adopted, so that the abutting part is not easy to fall off and dislocation.

Wherein, the top of the sliding block 32 is provided with a sliding groove 323 and a block 324 arranged in the sliding groove 323, the pull rod 34 includes a connecting end 341 and a hook end 342, and the connecting end of the pull rod 34 341 is movably connected (hinged) to the bottom shell 311, and the hook end 342 of the pull rod 34 is arranged in the sliding groove 323.

Specifically, the chute 323 includes an eject chute 3231 and a retraction chute 3232. One end of the eject chute 3231 and the retraction chute 3232 forms a common chute 3233, and the other end is connected to form a card. Into the space 3234, the block 324 is located between the ejecting slide 3231 and the retracting slide 3232. At a position close to the common slide 3233, the depth of the ejecting slide 3231 is higher than that of the retraction slide 3233. The depth of the retracting slide 3232 is described to form a step A at the intersection of the two to force the subsequent hook end 342 to slide from the common slide 3233 into the retracting slide 3232 only. The snap-in space 3234 is in the shape of a "V". The snap-in space 3234 is provided with a wedge block 3235 that guides the hook end 342 to slide into the ejection slide 3231, and is also provided with a wedge block 3235 for preventing the hook end 342 from sliding. Enter the limit step 3236 of the retracting slide 3232. Through the design of these limit and guiding structures, it can ensure that the hook end slides smoothly along the set route, and it is not easy to appear stuck, jammed, path disorder and other restrictions, and ensure stable operation. It is understandable that when the camera 10 is in the retracted state (as shown in FIG. 1), the hook end 342 slides in the locking space 3234 and hooks the blocking block 324 (as shown in FIGS. 4 and 5). When the blocking block 324 cannot move, the camera 10 is locked; when in the retracted state, press the exterior surface of the camera 10 (the surface exposed outside the passage hole 212 when retracted), and push the camera 10 in the retracting direction (inward ) When moving the set stroke, the hook end 342 separates from the block 324 and slides into the eject slideway 3231, the locking effect is lost, and the traction spring 33 pulls the slider 32 to slide in the eject direction to push the slide bracket 22 to move forward. To eject the camera 10, the hook end 342 slides from the eject slide 3231 into the common slide 3233 (as shown in Figure 9); when in the ejected state, press the exterior surface of the camera 10 and push the camera 10 back When moving in the retracting direction, the hook end 342 slides from the public slide 3233 into the retract slide 3232, and finally slides into the card insertion space 3234. At this time, the camera 10 retracts into the through hole 212. After the pressing force is removed, the card The hook end 342 hooks the block 324 to lock the camera 10, and the camera returns to the retracted state.

It should be pointed out that the set stroke is the stroke required for the hook end 342 to slide from the locking space 3234 into the ejecting slide 3231, which can be adjusted by changing the size of the locking space 3234.

Wherein, a through hole is provided in the middle of the shell cover 312, a side wall of the through hole obliquely extends toward the inside of the housing 31 to extend the limiting elastic piece 35, and the limiting elastic piece 35 is close to the pull rod The top part of 34 to ensure that the hook end 342 of the pull rod 34 is always in the sliding groove 323.

It is understandable that when the slider 32 pushes the camera 10 to pop out, it will give thrust to one side of the camera 10, which will make the camera 10 have a tendency to deviate to the other side. The camera 10 is damaged, and the service life of the camera ejection mechanism is reduced. In order to solve the above problems, this embodiment further provides a balance guide assembly 40. The balance guide assembly 40 and the ejection assembly 30 are located on opposite sides of the camera 10, and the balance guide assembly 40 is used to guide the camera. 10Slide in the set direction.

Specifically, the balance guide assembly 40 includes a telescopic rod 41 and a telescopic spring 42 sleeved on the telescopic rod 41. The telescopic direction of the telescopic rod 41 is consistent with the sliding direction of the base plate 221, and one end is aligned with the sliding direction of the base plate 221. The camera 10 is connected, and the other end is connected to the mounting board 21. One end of the telescopic spring 42 is connected to the base plate 221 and the other end is connected to the mounting plate 21.

It is understandable that when the slider 32 pushes the camera 10 to pop out, it will give a pushing force on one side of the camera 10, and the telescopic spring 42 on the other side will also give a pushing force to the camera 10 under the action of elastic reset, thereby keeping the camera 10 Balance, avoid the phenomenon of unilateral force applied to the camera 10 during the sliding process, ensure the smooth operation of the camera, reduce the wear of the mechanism, and increase the service life.

Preferably, when the camera 10 is in the retracted state, the absolute value of the expansion and contraction of the telescopic spring 42 and the traction spring 33 is the same, that is, the tension of the telescopic spring 42 on the camera 10 is the same as that of the telescopic spring 42 on the camera 10 In this way, it can be ensured that the force on both sides of the camera 10 is equal at any position, and the camera 10 always maintains a balanced state and has a long service life.

In summary, the camera pop-up mechanism in this embodiment adopts a mechanical motion structure to realize the telescopic function of the camera 10. Press the appearance of the camera 10, the camera 10 pops up, and then presses again to retract and lock. The overall size is small and it occupies the entire machine. The space is small, the cost is low, and no live work is required. In addition, the stop elastic piece 35 is used to ensure that the hook end 342 of the pull rod 34 is always in the chute 323, and a balance guide assembly 40 is also provided to ensure that the camera 10 is always balanced, ensuring that the camera ejection mechanism is even in a high-intensity use state. (Such as repeatedly retracting the camera), it can also maintain stable operation, improving the stability and service life of the camera ejection mechanism.

Please refer to Figures 10 to 12, which show the camera ejection mechanism in the second embodiment of the present invention. The difference between the camera ejection mechanism in this embodiment and the camera ejection mechanism in the first embodiment is:

A sealing ring 2121 is embedded on the inner wall of the passing hole 212, and the sealing ring 2121 is in contact with the camera to increase the sealing performance.

In addition, a shock absorbing pad 3237 is embedded in the retracting slide 3232, and the shock absorbing pad 3237 is located below the step A. When the hook end 342 enters the public slide 3233 from the eject slide 3231, The impact of the hook end 342 falling from the step A will be absorbed by the shock-absorbing pad 3237, thereby eliminating the abnormal noise when the camera 10 is ejected.
