[0002] Currently, the most common ways to protect electronic products are through protective cases and covers. Protective covers, often made of leather, are prone to peeling, which many consumers dislike. Protective cases are widely compatible with various screen types, including standard flat-screen phones, foldable phones, and tablets. For easier viewing, cases with flip stands have been designed. However, existing cases of this type are generally made of rigid materials, making them inconvenient to install. Forcing them in can damage the paint, and removing the phone later is also difficult. Furthermore, the flip support mechanism in most cases lacks a rotation mechanism, making it impossible to adjust the angle of the support plate freely. In addition, many cases have a separate flip support frame from the camera, occupying a significant amount of space in the middle of the back panel, and the camera is not adequately protected.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] refer to Figures 1 to 15 :

[0034] This embodiment discloses a protective case with a flip support and automatic locking mechanism, including a back plate 1, a flip support mechanism 2, and a self-locking mechanism 3. One side of the back plate 1 has a first edge 4 for limiting the position of a mobile phone or tablet, and the other side of the back plate 1 has a detachable second edge 5. The first edge 4, the second edge 5, and the back plate 1 together form a receiving position 101 for placing electronic products (ordinary mobile phones, foldable screen phones, or tablets, etc., hereinafter using mobile phones as an example). Note that if this is used to place a foldable screen phone, this patent structure only shows one side; the installation method of the remaining screens is the same as in this patent. The self-locking mechanism 3 includes the second edge 5, a trigger switch 31, and a pulling component 32. One end of the pulling component 32 is connected to the second edge 5. One end is connected to the back panel 1 and drives the second edge 5 to always move closer to the back panel 1. The trigger switch 31 is located on one side of the back panel 1 and can pop up when the second edge 5 is pulled open to block the second edge 5 or release the obstruction of the second edge 5 when subjected to external force. In this way, one-key unlocking and one-key locking functions can be realized. The one-key unlocking here can be achieved by manually lifting the second edge 5 upward. The one-key locking here refers to when the phone is placed into the back panel 1, the back of the phone touches the trigger switch 31, the trigger switch 31 is pressed down so that there is no obstruction to the second edge 5, and the second edge 5 quickly closes to the back panel 1 under the pull of the pulling component 32, thereby forming a complete receiving position 101, wrapping the phone, completing the installation of the phone, and making it very convenient to use.

[0035] Specifically, the pulling assembly 32 includes a first spring 321, a first spring groove 322, and a spring guide rod 323. The back plate 1 has a first spring groove 322 on one side, which extends upwards to form a spring hole 324. The first spring 321 is disposed within the first spring groove 322, with one end of the first spring 321 fixed to the bottom of the groove. The bottom end face of the second edging 5 has a spring guide rod 323, which passes through the spring hole 324 and is fixedly connected to the other end of the first spring 321. Preferably, in order for the second edging 5 to... It is not easy to shake when pulled up or brought closer. The structure of the pulling component 32 can be set in two sets, symmetrically set on both sides of the central axis. The second edge 5 is also provided with a baffle 33 corresponding to the position of the trigger switch 31. The trigger switch 31 includes a trigger part 311 and a blocking part 312. The blocking part 312 is located at the lower end of the trigger part 311, and a set-in step 31a is formed between the trigger part 311 and the blocking part 312 for the baffle 33 to be locked in place. A trigger groove 11 is provided on one side of the back plate 1. The trigger switch 31 is mostly embedded in the trigger groove 11. The bottom of the blocking part 312 is provided with a second spring groove 31. 2a. A second spring 312b is provided in the second spring groove 312a. The bottom of the second spring 312b is fixedly connected to the trigger groove 11. The second spring 312b drives the trigger switch 31 to always push upward. When the second edge 5 is driven away from the back plate 1 by external force (pulled up by hand), the baffle 33 disengages from the locking step 31a, thereby driving the end face of the blocking part 312 to abut against the baffle 33. At this time, the second edge 5 is pulled towards the back plate 1 under the pull of the pulling assembly 32. However, due to the blocking cooperation between the baffle 33 and the blocking part 312, the second edge 5 cannot approach the back plate 1. Only when an external force pulls it away from the back plate 1 can the second edge 5 be pulled towards the back plate 1. When the trigger part 311 is pressed down, the blocking part 312 is displaced downward, thereby disengaging from the baffle 33. The second edge 5 quickly moves towards the back plate 1 under the pull of the pulling component 32. At this time, the baffle 33 is just inserted into the position of the insert step 31a. It is equivalent to the insert step 31a providing a clearance space for the baffle 33 when the second edge 5 and the back plate 1 are closed. When the second edge 5 is pulled up, the blocking part 312 pushes upward under the upward elastic force, thereby blocking the baffle 33. The baffle 33 is protruding from the end face of the second edge 5, so the second edge 5 cannot move towards the back plate 1.

[0036] Specifically, the flip support mechanism 2 has one end rotatably mounted on the back plate 1 and the other end folding outward to form a flip support structure. Specifically, the flip support mechanism 2 includes a support plate 21, a rotating groove 22, a rotating seat 23, a rotating shaft 24, an adapter piece 25, and a circular rivet 26. The back plate 1 has a recessed rotating groove 22 on one side. The convex shaft end 231 of the rotating seat 23 is nested within the rotating groove 22 from one end of the back plate 1. The rotating seat 23 is equipped with a rotating shaft 24, which is rotatably mounted on the rotating seat 23. One end of the adapter piece is rotatably connected to the rotating shaft 24, and the other end is fixedly connected to one end of the support plate 21. The circular rivet... 26 is riveted to the rotating seat 23 from the other side of the back plate 1, thereby forming an upper and lower annular limiting rotation mechanism. The rotation of this rotating mechanism is achieved by the cooperation of the convex shaft end 231 of the rotating seat 23 with the rotating groove 22. Through this structure, the support plate 21 can be flipped relative to the rotating seat 23 by means of the adapter plate and the rotating shaft 24, and the rotating seat 23 can rotate 360 ​​degrees relative to the rotating groove 22. It is equivalent to the support plate 21 carrying the rotating seat 23 rotating relative to the rotating groove 22, so that the support angle of the support plate 21 can be changed at will. It can achieve a good viewing effect by placing the device vertically, horizontally, or upside down.

[0037] In order to make the support plate 21 in this device more stable when rotating and to obtain a better rotation feel and texture, in this patent, the annular groove surface of the rotating groove 22 is provided with annular damping teeth 27, and a spring glass ball 28 is provided on one side of the rotating seat 23. The output end of the spring glass ball 28 is aligned with the damping teeth. The damping teeth cooperate with the spring glass ball 28, which enables the support plate 21 to make a clicking sound when rotating.

[0038] Specifically, the rotating groove 22 has a first groove 29 and a second groove 30 on both sides, the rotating seat 23 includes a convex shaft end 231 and a cover plate end 232, wherein the convex shaft end 231 extends into the rotating groove 22, the cover plate end 232 is circumferentially rotated with the first groove 29, the circular rivet 26 is circumferentially rotated with the second groove 30, and the spring glass ball 28 and the rotating shaft 24 are both located on one side of the convex shaft end 231.

[0039] Specifically, the back plate 1 has a flange 12 on its back side. The flange 12 has a semi-circular clearance groove 121 and an opening groove 122 corresponding to the positions of the rotating seat 23 and the support plate 21, respectively. The support plate 21 includes a support end 211 and a connecting end 212. The connecting end 212 is fixedly connected to the adapter piece 25 and can be fitted into the opening groove 122. The design of the opening groove 122 and the connecting end 212 allows the support plate 21 to be placed in a position parallel to the device when not in use, and also allows the support plate 21 to be rotated. When rotating, a certain limit is formed, which can be better adjusted to the commonly used angle, namely horizontal and vertical. Preferably, the adapter piece 25 is connected to the inner side of the connecting end 212. With this setting, the end face of the connecting end 212 will abut against the end face of the cover end 232 of the rotating seat 23 when the support plate 21 is opened. In this way, the protective shell can be erected and is supported by the lever-type stable support of the support plate 21. That is, the maximum opening angle of the support plate 21 is limited by the end face of the connecting end 212 and the end face of the cover end 232, thereby providing strong support for the entire protective shell.

[0040] Specifically, unlike the traditional flip support mechanism 2 installed in the middle of the back plate 1 that can only flip and support, in this patent, the support end 211 has a camera cover 211a, and the camera cover 211a is provided with a camera hole 211b. The back plate 1 is provided with a camera clearance groove 13 corresponding to the camera cover 211a. The support end 211 is made into a camera cover 211a. When not opened, the camera cover 211a can play a good protective role for the mobile phone camera. When it is needed, the camera clearance groove 13 will not block the mobile phone camera.

[0041] Specifically, the self-locking mechanism 3 further includes an unlocking component 6, which includes an unlocking switch component 6A and a driven component 6B. The upper end of the back plate 1 is provided with a first unlocking groove 61 and a second unlocking groove 62 at two symmetrical positions. The first unlocking groove 61 is provided with a first through groove 63, and the second unlocking groove 62 is provided with a second through groove 64. The unlocking switch includes a left switch 65 and a right switch 66, wherein the left switch 65 slides in the first through groove 63, and the right switch 66 slides in the second through groove 64. The left switch 65 is provided with a first inclined surface 661, and the right switch 66 is provided with a second inclined surface 662. The driven component 6B includes a left driven block 67 and a right driven block 68 that can be inserted into the first unlocking groove 61 and the second unlocking groove 62, respectively. The left driven block 67 and the right driven block 68 are both located at the bottom of the second edge 5. The first inclined surface 661 is driven to cooperate with the inclined surface of the left driven block 67, and the second inclined surface 662 is driven to cooperate with the inclined surface of the right driven block 68.

[0042] Specifically, both the left switch 65 and the right switch 66 include a lever part 651, a sliding part 652, and a shaft connecting part 653. The lever part 651 is located on the outer side of the back plate 1. The sliding part 652 is slidably disposed in the first unlocking groove 61 or the second unlocking groove 62. The shaft connecting part 653 is embedded in the first through groove 63 or the second through groove 64. In use, one only needs to use the index finger and thumb to simultaneously pry the lever part 651 of the left switch 65 and the right switch 66 in opposite directions. The first inclined surface 661 and the first inclined surface 661... The left driven block 67 and the second inclined surface 662 cooperate with the right driven block 68, causing the left driven block 67 and the right driven block 68 to slide upwards, which is equivalent to the effect of a person directly pulling the second edge 5 by hand. Then the second edge 5 is forced to separate from the back plate 1. Then, the separation of the second edge 5 is completed by the cooperation of the trigger switch 31 and the blocking block. In this way, one-click unlocking is achieved. After unlocking, the phone can be taken out of the easy-to-use position 101 to complete the removal or the phone can be put in to complete the installation. It is simple to use.
