[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In the present invention, the directions or positional relationships indicated by the terms "upper", "lower", "inner", etc. are based on the directions or positional relationships shown in the accompanying drawings. Moreover, in addition to being used to indicate directions or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases.

[0040] In addition, the terms "disposed", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components.

[0041] The terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0042] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0043] Please also read Figures 1 to 3 The present application discloses a locking structure 100, which can be used to lock a screen assembly in a display screen. Specifically, the display screen 200 includes: a screen assembly 201 and a locking structure 100, wherein the screen assembly 201 includes a screen body 2011 and a mounting frame 2012. The screen body 2011 is arranged on the mounting frame 2012, and the mounting frame 2012 is provided with a card slot 2012a corresponding to the locking structure 100, and the card slot 2012a is used to connect with the locking structure 100 when the locking structure 100 is extended, so that the locking structure 100 locks the screen body 2011.

[0044] It is understandable that the display screen 200 can be used in an environment where bumps may occur, such as a car. The following uses the car as an example. When bumps occur, the locking structure 100 can be used to lock the screen assembly 201 to prevent the screen assembly 201 from hitting the body of the passenger in the car due to the bumps. It can be seen that the display screen has high safety.

[0045] In addition, the display screen 200 of this embodiment can also be used in environments such as airplanes and ships where turbulence may occur during operation, and has the same beneficial effects, which is not limited in this embodiment.

[0046] It is understandable that the display screen 200 may be a flip screen or a movable display screen.

[0047] The specific structure of the locking structure 100 of the present application will be described in detail below with reference to the accompanying drawings.

[0048] Please also read Figures 3 to 6The locking structure 100 includes: a base 1, a locking assembly 2 and an unlocking assembly 3. The locking assembly 2 includes a locking member 21 and a first elastic member 22. The locking member 21 includes a locking portion 211 and a linkage portion 212 disposed on the locking portion. The linkage portion 212 is rotatably connected to the base 1. The first elastic member 22 is connected to the locking portion 211 and the base 1. The first elastic member 22 is used to provide a force for the locking portion 211 to extend to lock the object to be locked. The unlocking assembly 3 is disposed on the base 1, and the unlocking assembly 3 is connected to the linkage portion 212. The unlocking assembly 3 is used to make the linkage portion 212 rotate relative to the base 1 to drive the locking portion 211 to retract relative to the object to be locked.

[0049] For example, the object to be locked can be the display screen 200 mentioned above, specifically the mounting frame 2012, that is, the locking portion 211 is arranged corresponding to the card slot 2012a, and when the locking portion 211 is extended, it is connected with the card slot 2012a to lock the display screen 200, and when the locking portion 211 is retracted, it is separated from the card slot 2012a, and the display screen 200 is unlocked so that it can be turned over. Of course, in other examples, the object to be locked can also be other objects that need to be locked, such as a camera module, a handheld game console, etc.

[0050] The locking structure 100 disclosed in the present application drives the locking member 21 to rotate around the base 1 and extend through the contraction of the first elastic member 22, and the locking portion 211 is engaged with the object to be locked, so that the object to be locked is locked; the unlocking component 3 is pressed, and the unlocking component 3 drives the linkage portion 212 to rotate around the base 1, the locking member 21 is retracted, and the locking portion 211 is separated from the object to be locked, so as to unlock. It can be seen that the locking structure 100 does not need to use an additional motor drive, has a simple structure and a more compact overall structure, which is conducive to reducing the volume of the locking structure 100, and can reduce the impact on the layout of other components inside the car.

[0051] In some embodiments, the base 1 includes a first substrate 11, and two branches 111 are provided on the first substrate 11. The two branches 111 are arranged at intervals, and the two branches 111 are provided with shaft holes opening toward each other, and the linkage part 212 is passed through the two shaft holes through a rotating shaft to be rotatably connected to the first substrate 11. Since the linkage part 212 and the base 1 are rotatably connected, the connection between the two is easily worn, and the linkage part 212 and the base 1 are connected by a rotating shaft. The rotating shaft can be made of a material with a higher hardness than the linkage part 212 and the base, which can extend the life of the rotating shaft, thereby improving the reliability of the locking structure 100.

[0052] Optionally, the first substrate 11 is a long strip, and the first substrate 11 is roughly an L-shaped plate, including a horizontal plate portion 112 and a vertical plate portion 113, and the branch 111 is arranged on the vertical plate portion 113, so that the linkage part 212 is not easy to interfere with the base when it is connected to the base 1 through the rotating shaft, which is conducive to the normal operation of the linkage part 212.

[0053] Furthermore, the base 1 further comprises a second substrate 12, which is arranged on one side of the first substrate 11, and two support plates 121 are arranged on the second substrate 12, and the two support plates 121 are arranged at intervals to form an installation space, and each support plate 121 is provided with a limiting portion 1211, and the unlocking component 3 is at least partially located in the installation space, and the limiting portion 1211 is connected to the unlocking component 3 to limit the position of the unlocking component 3 in the installation space. The support plate 121 can limit the unlocking component to prevent the unlocking component 3 from deviating in the direction where the support plate 121 is arranged, and the limiting portion 1211 can prevent the unlocking component from escaping from the installation space when unlocking, thereby disengaging from the linkage portion 212, which is conducive to improving the reliability of the locking structure 100.

[0054] Optionally, the second substrate 12 is connected to the side of the vertical plate portion 113 facing away from the horizontal plate portion 112, so that the second substrate 12 is roughly parallel to the horizontal plate portion 112, and along the vertical direction, the height of the second substrate 12 connected to the vertical plate portion 113 is greater than the height of the horizontal plate portion 112 connected to the vertical plate portion, so that, along the vertical direction, a height difference is formed between the second substrate 12 and the horizontal plate portion 112, so that when the base 1 is installed on a stepped surface or a curved surface, the first substrate 11 and the second substrate 12 can fit better, which is beneficial to the stable installation of the locking structure.

[0055] In some embodiments, the locking portion 211 is roughly hook-shaped, and the linkage portion 212 may be a block-shaped structure, which is arranged at the bottom of the locking portion 211. A convex shaft may be formed on the linkage portion 212, and the convex shaft is provided with the shaft hole to cooperate with the rotating shaft to achieve a rotatable connection with the first substrate 11.

[0056] Furthermore, a plurality of reinforcing ribs are provided on the back side of the locking portion 211 (i.e., the side away from the side used to lock the object to be locked), and the reinforcing ribs extend from the connection between the locking portion 211 and the linkage portion 212 to the end of the locking portion 211 away from the linkage portion 212. When the locking portion 211 locks the object to be locked, the object to be locked may be bumped and may impose additional load on the locking portion. Based on this, providing the reinforcing ribs is beneficial to improving the strength of the locking portion 211 and the linkage portion, thereby helping to increase the reliability of the locking structure 100.

[0057] In some embodiments, the first elastic member 22 may be a tension spring, which has high strength and long life, and is conducive to improving the reliability of the locking structure 100. Of course, in other embodiments, the first elastic member 22 may also be a rubber elastic ring, a spring, etc.

[0058] Optionally, when the first elastic member 22 is connected to the base 1 and the locking portion 211, it is mainly connected to the first substrate 11 and the locking portion. Specifically, a first fixing portion 13 is provided on the vertical plate portion 113 of the first substrate 11, and a second fixing portion 23 is provided on the locking portion. Both ends of the first elastic member 22 can be connected to the first fixing portion 13 and the second fixing portion 23 respectively, so as to realize the connection between the first elastic member 22 and the base 1 and the locking portion 211.

[0059] For example, since the first elastic member 22 can be a tension spring, a convex block is provided on the vertical plate portion 113, the first fixing portion 13 can be a convex strip provided on the convex block, and the second fixing portion 23 can also be a convex strip, so that the two ends of the tension spring can be respectively sleeved on the corresponding convex strips to prevent the tension spring from detaching from the corresponding convex strips. Specifically, a notch can be provided on the second fixing portion 23, so that when the tension spring is connected to the second fixing portion 23, it can be stuck in the notch to avoid detaching from the second fixing portion 23.

[0060] Optionally, in order to make the force of the first elastic member 22 on the locking portion 211 more balanced, the first elastic member 22 can be set to two, and correspondingly, the first fixing portion 13 and the second fixing portion 23 can be two. Specifically, two spaced protrusions are provided on the vertical plate portion 113, and the two first fixing portions 13 are respectively arranged on the two protrusions, and the two first fixing portions 13 are arranged facing each other. Similarly, the two second fixing portions 23 are spaced apart on the locking portion 211. It can be understood that in other embodiments, the first elastic member 22 can also be set to one or more, such as three, four, etc.

[0061] In some embodiments, the locking structure 100 further includes a decorative plate 4, on which a void hole 41 is provided, through which the unlocking assembly 3 is inserted, and at least a portion of the unlocking assembly 3 is exposed from the void hole 41. The provision of the decorative plate 4 can prevent dust and water from entering the connection between the locking assembly 2 and the base 1, reduce the erosion of the locking assembly 2, and help to improve the life of the locking structure 100. In addition, the unlocking assembly 3 is at least partially exposed from the void hole 41, so that the user can operate the unlocking assembly 3 through the void hole 41.

[0062] In some embodiments, the unlocking assembly 3 may include a pressing member 31 and a driving member 32. The pressing member 31 includes a pressing portion 311 and a connecting portion 312 disposed on the pressing portion 311. The pressing portion is disposed substantially corresponding to the air-avoiding hole 41 and at least partially exposed from the air-avoiding hole 41. The connecting portion 312 is connected to the linkage portion 212, and the driving member 32 is connected to the base 1 and the connecting portion 312. When the pressing portion 311 is pressed, the connecting portion 312 drives the linkage portion 212 to rotate relative to the base 1, so as to drive the locking portion 211 to retract relative to the object to be locked. The driving member 32 is used to drive the pressing portion 311 to reset when the pressing effect of the pressing portion 311 disappears, so that the first elastic member 22 drives the locking portion 211 to extend, thereby locking the object to be locked. In other words, only when the pressing portion 311 is pressed can the locking portion 211 be retracted relative to the object to be locked and thus unlocked. When the pressing portion 311 is released, due to the action of the first elastic member 22, the locking portion 211 is extended to lock the object to be locked. That is, the locking structure 100 of this embodiment is a structure that is locked under normal conditions. This can reduce the possibility of unlocking the locking structure 100 due to vehicle bumps or accidental touch by passengers. It can be seen that the locking structure 100 of this embodiment has higher reliability.

[0063] In an optional embodiment, the pressing member 31 may be a button, and the driving member 32 may be a second elastic member 321, such as a spring. The second elastic member 321 is connected to the base 1 and the pressing portion 311. The second elastic member 321 is used to drive the pressing portion 311 to reset, so that the first elastic member 22 drives the locking portion 311 to extend, thereby locking the object to be locked. Since only the second elastic member 321 is needed to realize the function of driving the pressing portion 311 to reset, the structure is relatively simple, which is conducive to reducing the cost of the locking structure 100.

[0064] In another optional embodiment, the pressing member 31 is also a button, but the driving member 32 includes an electromagnet and a second elastic member 321 (such as a spring), and the electromagnet is used to generate an attractive force to press the pressing portion 311 downward, so that the connecting portion 312 drives the linkage portion 212 to rotate relative to the base 1, and then the locking portion 211 is retracted. The electromagnet can be connected to the vehicle system of the car or the passenger's mobile terminal, so that the locking structure 100 can be remotely controlled. In this way, when the display screen 200 needs to be unlocked, the passenger can remotely unlock the display screen 200 and then use both hands to adjust the angle of the display screen 200 without occupying the passenger's single hand to press the pressing portion 311, which is conducive to optimizing the user's experience of the display screen 200. It is understandable that the electromagnet can be configured so that after the display screen 200 stops being used, that is, the power is turned off and the attractive force is lost, the second elastic member 321 drives the pressing portion 311 to reset, and the locking portion 211 extends to lock the display screen 200, so as to avoid the situation where the passenger forgets to lock the display screen 200, which is conducive to improving the safety of the display screen 200.

[0065] It can be seen that by adopting the method of combining the electromagnet with the second elastic member 321 , there is no need for the user to manually press the pressing member 31 , and the operation is more convenient.

[0066] In this embodiment, the driving member is the second elastic member 321 as an example. A connecting column 314 is provided on one side of the pressing member 31 close to the base 1, one end of the second elastic member 321 is connected to the connecting column 314, and the other end is connected to the second substrate 12. The connection column 314 is provided to shorten the distance between the pressing member 31 and the second substrate 12, thereby reducing the length of the second elastic member 321. Assuming that the length of the second elastic member 321 is too long, when the pressing member 31 is pressed, the second elastic member 321 is prone to instability, that is, when the elastic member 321 is compressed, it is not vertically compressed and deformed but bends. At this time, the force provided by the second elastic member 321 to the pressing member 31 will be greatly reduced, affecting the reset of the pressing member 31. Based on this, by providing the connection column 314, the length of the second elastic member 321 can be reduced, which is conducive to avoiding the occurrence of instability, thereby improving the reliability of the locking structure 100.

[0067] Optionally, a guide hole 314a is provided on the connecting column 314, and a guide column 122 is correspondingly provided on the second substrate 12. When the pressing member 31 is pressed, the guide column 122 extends into the guide hole 314a to guide the pressing member 31. When the pressing member 31 is not pressed, the guide column 122 is disengaged from the guide hole 314a. When the pressing member 31 is pressed, the pressing member 31 is disengaged from the air avoidance hole 41, and the restraining effect of the air avoidance hole 41 on the pressing member 31 is weakened, and the pressing member 31 is prone to displacement. The cooperation between the guide hole 314a and the guide column 122 avoids the occurrence of such displacement, thereby facilitating the reliability of the locking structure 100.

[0068] In some embodiments, the linkage part 212 has a first curved surface 2121 on a side away from the locking part 211, and a second curved surface 312a is formed on a side of the connection part 312 away from the pressing part 311, and the second curved surface 312a is matched and connected with the first curved surface 2121 to realize a movable connection between the connection part 312 and the linkage part 212. In the process of pressing the connection part 312 downward to drive the linkage part 212 to rotate relative to the base 1, the movement of the first curved surface 2121 relative to the second curved surface 312a is actually a combination of rotation and translation along the extension direction of the linkage part 212. The design of the first curved surface 2121 and the second curved surface 312a fitting each other can reduce the occurrence of jamming during this movement, thereby making the pressing process of the pressing part 311 smoother, which is conducive to improving the user experience.

[0069] Optionally, a protrusion 2122 is provided on the side of the linkage part 212 away from the locking part 211, and the protrusion 2122 has a first arc surface 2121. The protrusion 2122 is connected with the connecting part 312 to realize the movable connection between the connecting part 312 and the linkage part 212. In this way, the bottom of the protrusion 2122 can better fit with the connecting part 312, which can reduce the occurrence of jamming during this movement, so that the pressing process of the pressing part 311 is smooth, which is conducive to improving the user experience.

[0070] Optionally, the connecting portion 312 is a block structure, on which a plurality of reinforcing plates 313 are arranged, one end of each reinforcing plate 313 is connected to the pressing portion 311, and the other end of each reinforcing plate 313 extends to the second curved surface 312a, and the plurality of reinforcing plates 313 are arranged at intervals along the pressing direction perpendicular to the pressing portion 311; the reinforcing plates 313 are used to increase the strength of the connecting portion 312. As mentioned above, the movement of the first curved surface 2121 relative to the second curved surface 312a is actually a combination of rotation and translation along the extension direction of the linkage portion 212. In the process of the pressing portion 311 pressing down and resetting, the magnitude and direction of the load on the connecting portion 312 are changing, and the force condition is relatively complex. The reinforcing plates 313 are arranged to increase the strength of the connecting portion 312, which is conducive to improving the reliability of the connecting portion 312 when facing such complex loads, and further conducive to increasing the reliability of the locking structure 100.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
