DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0036] Reference Figures 1 to 10 As shown, this embodiment provides an electronic device, which can be, for example, a vehicle-mounted display device, etc. Specifically, the electronic device includes a frame 1 , a display screen 2 , a locking tongue 3 , a base 4 and a pressing member 5 .

[0037] The display screen 2 is arranged on the frame 1 and can rotate around a rotation axis relative to the frame 1. A locking groove 21 is arranged at one end of the display screen 2 away from the rotation axis, and an accommodating cavity 11 is arranged at a position corresponding to the locking groove 21 on the frame 1. The base 4 is located in the accommodating cavity 11 and the locking tongue 3 is located on a side of the base 4 close to the locking groove 21.

[0038] An opening 12 is provided on one side of the frame 1, and a through hole 41 connected to the opening 12 is provided on the base 4. The pressing piece 5 is penetrated in the through hole 41 and the opening 12. When the pressing piece 5 moves toward the opening close to the opening 12, the base 4 can move toward the direction close to the locking groove 21 under the drive of the pressing piece 5, so that the locking tongue 3 is inserted into the locking groove 21 to limit the rotation of the display screen 2; or when the pressing piece 5 moves toward the direction away from the opening, the base 4 can move toward the direction away from the locking groove 21 under the drive of the pressing piece 5, so that the locking tongue 3 is moved out of the locking groove 21 to release the rotation restriction of the display screen 2.

[0039] When implementing it, refer to Figure 1 and Figure 2As shown, a receiving groove can be provided on one side of the frame 1, and the display screen 2 is provided in the receiving groove and can rotate relative to the frame 1 around a rotation axis, so that the display screen 2 can rotate relative to the frame 1 to a vertical state, that is, Figure 2 Alternatively, the display screen 2 can be rotated relative to the frame 1 until it is stored in the receiving groove, as shown in FIG. Figure 1 Shown in stowed position.

[0040] Reference Figure 4 In the left and right directions of the drawings shown, the left end of the display screen 2 is arranged to rotate around a rotating shaft, and a locking groove 21 can be arranged at the right end of the display screen 2. A receiving cavity 11 is arranged at a position corresponding to the locking groove 21 on the frame 1, and a base 4 is arranged in the receiving cavity 11. The locking tongue 3 is located on the left side of the base 4, so that the locking tongue 3 can be inserted into the locking groove 21 to lock the display screen 2 or moved out of the locking groove 21 to unlock the display screen 2.

[0041] Specifically, the specific structure and process of the lock tongue 3 inserting or removing the lock groove 21 can be as follows: the lower side of the frame 1 can be provided with an opening 12, and the base 4 is provided with a through hole 41 connected to the opening 12 at a position corresponding to the opening 12, so that the pressing member 5 can be inserted into the opening 12 and the through hole 41, so that the pressing member 5 is pressed and the pressing member 5 is moved along the Figure 3 and Figure 4 When moving in the up-and-down direction as shown, the base 4 is driven to move left and right, so that the locking tongue 3 moves left and right to be inserted into the locking groove 21 or moved out of the locking groove 21 .

[0042] When implementing it, refer to Figure 3 As shown, when the display screen 2 is rotated to the position shown in Figure 1 In the retracted state shown, in order to lock the display screen 2 to prevent it from rotating, it is necessary to insert the locking tongue 3 into the locking groove 21 of the display screen 2. At this time, the pressing member 5 can be moved toward the direction close to the hole, that is, downward, thereby driving the base 4 to move to the left, thereby driving the locking tongue 3 to move to the left until it is inserted into the locking groove 21 to lock the display screen 2.

[0043] Reference Fig. 9 As shown, when the display screen 2 needs to be unlocked from the retracted state so as to be turned over, that is, the lock tongue 3 needs to be moved out of the locking groove 21, at this time, the pressing member 5 can be moved in a direction away from the hole, that is, upward, thereby driving the base 4 to move to the right, thereby driving the lock tongue 3 to move to the right and move out of the locking groove 21, thereby unlocking the display screen 2. At this time, the display screen 2 can be rotated relative to the frame 1, so that it can be rotated to the position shown in the figure. Figure 2 Shown in flip open position.

[0044] In summary, in the electronic device provided by the present embodiment, when it is necessary to unlock the display screen 2 so that the display screen 2 can be flipped to the flipped state for viewing, the pressing member 5 can be manually pressed to move the pressing member 5 in a direction away from the hole, thereby driving the base 4 to move in a direction away from the locking groove 21, so that the lock tongue 3 on one side of the base 4 can be moved out of the locking groove 21 to release the lock of the lock tongue 3 on the display screen 2, and the display screen 2 can be rotated relative to the frame 1. When it is necessary to lock the display screen 2 in the retracted state, the pressing member 5 can be moved in a direction close to the hole, thereby driving the base 4 to move in a direction close to the locking groove 21, so that the lock tongue 3 can move in a direction close to the locking groove 21 and be inserted into the locking groove 21 to limit the display screen 2 from flipping relative to the frame 1. That is, the electronic device of the present utility model embodiment can realize the locking or unlocking of the display screen 2 by the lock tongue 3 by mechanically pressing the pressing member 5, without using an electric drive such as a motor to drive the lock tongue 3 to realize the locking or unlocking of the display screen 2, so there is no need to rely on power resources, which is conducive to energy saving and environmental protection.

[0045] Reference Figures 4 to 7 As shown, in some embodiments, a slot 42 is provided on one side of the base 4 close to the locking slot 21 , and a portion of the locking tongue 3 is located in the slot 42 .

[0046] When implementing it, refer to Figure 4 In the left and right directions of the drawing shown, a slot 42 can be provided on the left side of the base 4, and part of the lock tongue 3 is located in the slot 42. When the display screen 2 needs to be locked, the part of the lock tongue 3 located outside the slot 42 is inserted into the locking slot 21; when the display screen 2 needs to be unlocked, the part of the lock tongue 3 located in the locking slot 21 is moved out of the locking slot 21.

[0047] Reference Figures 4 to 7 As shown, in some embodiments, the lock tongue 3 includes a lock tongue body 31 and a first elastic member 32, the first elastic member 32 is located in the slot 42 and one end of the first elastic member 32 is connected to the bottom of the slot 42, and the other end of the first elastic member 32 is connected to the lock tongue body 31, and the lock tongue body 31 is used to be inserted into the locking groove 21 when the base 4 moves toward the direction close to the locking groove 21 to limit the display screen 2 from flipping.

[0048] When implementing it, refer to Figure 3 and Fig.10As shown, after the display screen 2 is unlocked, that is, the lock tongue body 31 is moved out of the locking groove 21, when the display screen 2 needs to be locked again, the pressing member 5 drives the base 4 to move in the direction toward the locking groove 21, thereby driving the lock tongue body 31 in the direction toward the locking groove 21. In the process, as the pressing member 5 moves in the direction toward the hole, the lock tongue body 31 moves in the direction toward the hole along with the pressing member 5. When the lock tongue body 31 moves to be flush with the locking groove 21, the lock tongue body 31 can move in the direction toward the locking groove 21 under the action of the elastic restoring force of the first elastic member 32 until it is inserted into the locking groove 21, so as to achieve the locking of the display screen 2. For details, refer to Figure 3 shown.

[0049] Correspondingly, when the display screen 2 needs to be unlocked, the lock tongue body 31 moves out of the locking groove 21 as the pressing member 5 moves in the direction away from the orifice, so that the first elastic member 32 is compressed, so as to provide an elastic restoring force for the lock tongue body 31 to move in the direction close to the locking groove 21 when the display screen 2 needs to be locked later.

[0050] Exemplarily, the first elastic member 32 may be a spring, the left end of the spring is connected to the lock tongue body 31, and the right end of the spring is connected to the bottom of the slot 42. Exemplarily, the first elastic member 32 may be one or more, and when multiple first elastic members 32 are provided, the multiple first elastic members 32 may be arranged at intervals along the width direction or thickness direction of the frame 1, so that the multiple first elastic members 32 may jointly provide elastic restoring force to the lock tongue body 31, so as to further ensure that the lock tongue body 31 can smoothly move into the locking groove 21, so as to achieve locking of the display screen 2.

[0051] Reference Figures 4 to 7 As shown, in some embodiments, one side of the lock tongue body 31 close to the locking groove 21 has a lock tongue slope 33. Along the direction from the locking groove 21 to the lock tongue body 31, the lock tongue slope 33 is inclined in the direction toward the orifice so that the lock tongue body 31 can move smoothly into the locking groove 21 under the guidance of the lock tongue slope 33.

[0052] When implementing it, refer to Figure 4 In the left-right and up-down directions of the drawing shown, the left side surface of the lock tongue body 31 has a lock tongue inclined surface 33, and the lock tongue inclined surface 33 can be inclined toward the lower right.

[0053] Reference Figures 4 to 10As shown, in some embodiments, the pressing member 5 moves toward the direction of the orifice, thereby driving the base 4 to move toward the direction close to the locking groove 21 and allowing the lock tongue 3 to be inserted into the locking groove 21 to achieve locking of the display screen 2. The pressing member 5 moves in the direction away from the orifice, thereby driving the base 4 to move in the direction away from the locking groove 21 and allowing the lock tongue 3 to move out of the locking groove 21 to achieve unlocking. The specific structure can be: the side of the pressing member 5 facing the lock tongue 3 has a first abutting surface 51, and the hole wall of the through hole 41 has a second abutting surface 411 that cooperates with the first abutting surface 51. The base 4 is used to move in the direction close to the locking groove 21 driven by the pressing member 5 when the pressing member 5 moves in the direction away from the orifice until the first abutting surface 51 and the abutting surface cooperate. The side of the pressing member 5 facing the locking tongue 3 has a groove 52 that is recessed in the direction away from the locking groove 21, and the top wall of the groove 52 is formed as a first stop slope 521. The hole wall of the through hole 41 has a second stop slope 412 that cooperates with the first stop slope 521. The base 4 is used to move in the direction away from the locking groove 21 driven by the pressing member 5 when the pressing member 5 moves toward the direction close to the hole opening until the first stop slope 521 and the second stop slope 412 cooperate.

[0054] When implementing it, refer to Figure 3 As shown, for example, the current state is the locked state, at which time the first abutting surface 51 on the left side of the pressing member 5 abuts against the second abutting surface 411 on the hole wall of the through hole 41. When the display screen 2 needs to be unlocked, the pressing member 5 can be moved upward, so that the first abutting surface 51 moves upward and disengages from the second abutting surface 411. As the pressing member 5 continues to move upward, the first stop bevel 521 begins to cooperate with the second stop bevel 412. Since the first stop bevel 521 is formed by the top wall of the groove 52 that is concave on the left side of the pressing member 5 in the direction away from the locking groove 21, when the first stop bevel 521 and the second stop bevel 412 cooperate, the base 4 will move in the direction away from the locking groove 21 and the lock tongue 3 will move out of the locking groove 21 to release the lock of the display screen 2.

[0055] Similarly, refer to Fig. 9 As shown, the current state is set to the unlocked state, at which time the first stop bevel 521 on the left side of the pressing member 5 abuts against the second stop bevel 412 on the hole wall of the through hole 41. When the display screen 2 needs to be locked, the pressing member 5 can be moved downward, so that the first stop bevel 521 moves downward and disengages from the second stop bevel 412. As the pressing member 5 continues to move downward, the first abutting surface 51 begins to cooperate with the second abutting surface 411. At this time, the base 4 moves toward the direction close to the locking groove 21 and the lock tongue 3 is inserted into the locking groove 21 to lock the display screen 2.

[0056] Reference Figures 4 to 7 As shown, in some embodiments, along the direction from the locking tongue 3 to the pressing member 5, the first stop inclined surface 521 is inclined toward the direction close to the hole, and the second stop inclined surface 412 is inclined toward the direction close to the hole.

[0057] When implementing it, refer to Figure 4 In the left-right and up-down directions of the drawing shown, the first abutting surface 51 and the second abutting surface 411 may both be vertical surfaces, and the first stop inclined surface 521 and the second stop inclined surface 412 may both be inclined surfaces inclined toward the lower right side.

[0058] Reference Figures 4 to 7 As shown, in some embodiments, the side of the groove 52 facing the locking groove 21 has a third abutting surface 522, and the third abutting surface 522 is used to abut against the second abutting surface 411 when the first stop inclined surface 521 and the second stop inclined surface 412 cooperate.

[0059] In specific implementation, when the first stop bevel 521 and the second stop bevel 412 cooperate, the side of the groove 52 facing the locking groove 21 can be set to form a third top surface 522, so that the third top surface 522 cooperates with the second top surface 411, that is, at this time, part of the base 4 can be inserted into the groove 52 of the pressing member 5 to achieve reliable cooperation between the base 4 and the pressing member 5.

[0060] Reference Figures 4 to 10 As shown, in some embodiments, a second elastic member 53 is provided on the side of the pressing member 5 facing away from the opening of the hole 12 , one end of the second elastic member 53 is connected to the pressing member 5 , and the other end of the second elastic member 53 is connected to the bottom wall of the opening 12 .

[0061] In a specific implementation, a second elastic member 53 is provided on the top surface of the pressing member 5, and the top end of the second elastic member 53 is connected to the bottom wall of the opening 12, so that when the pressing member 5 is manually pressed to move away from the hole, the pressing member 5 can move toward the direction close to the hole under the action of the elastic restoring force of the second elastic member 53 until it is reset, thereby realizing automatic reset of the pressing member 5.

[0062] Exemplarily, the second elastic member 53 may be a spring or other component with elastic restoring force. Exemplarily, the second elastic member 53 may be at least two, for example, Figure 6 The three shown may also be two or more.

[0063] Reference Figures 4 to 10As shown, in some embodiments, at least two third elastic members 43 are further provided on the base 4, and at least the third elastic members 43 are arranged on opposite sides of the pressing member 5, one end of the third elastic member 43 is connected to the base 4, and the other end of the third elastic member 43 can be used to cooperate with the display screen 2.

[0064] In specific implementation, after the display screen 2 is unlocked, that is, the lock tongue body 31 is moved out of the locking groove 21, when the display screen 2 needs to be locked again, the pressing member 5 drives the base 4 to move in a direction toward the locking groove 21. During this process, a third elastic member 43 can be provided on the base 4, so that the base 4 can move toward the locking groove 21 under the action of the elastic restoring force of the third elastic member 43.

[0065] Exemplarily, the third elastic member 43 may be, for example, a spring or other component with elastic restoring force. Exemplarily, the third elastic member 43 may be at least two, for example, Figure 6 The two shown may also be three or more.
