Description

Technical Field

[0001] The present application belongs to the field of automobile manufacturing technology, and specifically relates to a display screen back cover, an electronic device, and a vehicle-mounted display device. Background Art

[0002] With the continuous development of intelligent connected technology in the automotive industry, the number of in-car displays is increasing. This trend is particularly evident in the smart cockpit technology showcases at influential global auto shows. Examples include augmented reality (AR), heads-up displays (HUD), and digital instrument clusters. In addition, some smart cockpits also include a central control display and a passenger entertainment screen. Typically, smart cockpits feature a large, independent, floating screen with a simple, hollowed-out support. However, these screens cannot be adjusted to accommodate passengers of varying heights and body shapes.

[0003] In the related art, a support rod is set on the center console, and the end of the support rod is a ball pin. The ball pin cooperates with the mounting seat on the back cover of the display screen, specifically with the groove of the mounting seat. For example, part of the ball pin is engaged with the groove, thereby realizing the angle adjustment between the floating large screen and the support rod.

[0004] However, in the related art, when adjusting the angle of the large screen, the adjustment force cannot be controlled, and the large screen is easily rotated downward under the action of gravity, affecting the user experience. Summary of the Invention

[0005] The present application provides a display screen back cover, an electronic device, and a vehicle-mounted display device, which at least solve the problem in the related art that the adjustment force cannot be controlled when adjusting the angle of the display screen. The adjustment force can be adaptively adjusted according to display screens of different sizes or weights. In addition, the magnitude of the adjustment force can also be adjusted, which can effectively prevent the display screen from rotating downward.

[0006] According to a first embodiment of the present application, a display screen back cover is provided, comprising:

[0007] The back cover body is used to connect with the display screen;

[0008] A clamping portion is located on one side surface of the rear cover body, the clamping portion includes a plurality of clamping claws arranged in a circumferential manner, and the inner surface of the clamping portion is used to abut against the ball head of the display screen bracket and can rotate relative to the ball head;

[0009] The elastic limiting component is sleeved on the outer surfaces of the plurality of engaging parts.

[0010] In an optional design, the elastic limiting member is a limiting retaining spring, which includes a spring coil and at least one extension portion, and the spring coil is sleeved on the outer surface of the engaging portion; at least one extension portion is located at the opening of the spring coil, and the extension portion extends radially outward along the spring coil.

[0011] In an optional design, there are two extension parts, which are arranged opposite to each other at the opening.

[0012] In an optional design, the display screen back cover further includes an unlocking latch, which is movably disposed on the back cover body and located radially outside the opening along the spring coil, and has a width greater than a width of the opening.

[0013] At least a portion of the unlocking latch can selectively extend into the opening to expand the opening.

[0014] In an optional design, the end of the unlocking pin facing the elastic limiting member is tapered.

[0015] In an optional design, a latch limiter is provided on the rear cover body, which is located on the radial outside of the opening along the spring coil. A limit groove along the radial direction of the spring coil is formed between the latch limiter and the rear cover body, and the unlocking latch is located in the limit groove.

[0016] In an optional design, the rear cover body is further provided with a latch guide, which is located at the opening of the spring coil;

[0017] The latch guide is provided with a guide plane which extends along the movable direction of the unlocking latch, and the unlocking latch selectively moves along the guide plane.

[0018] In an optional design, the back cover of the display screen also includes a limiting ring, which is arranged on the outer periphery of the elastic limiting part, and the limiting ring and the elastic limiting part are clearance-matched; the limiting ring has an avoidance opening, and the extension part extends from the avoidance opening to the outside of the limiting ring.

[0019] In an optional design, the back cover body has a through hole, the engaging portion is located on the side of the back cover body facing the display screen, and a plurality of claws are arranged around the circumference of the through hole.

[0020] In an optional design, the display screen back cover further includes an unlocking handle, which is located on a side of the back cover body facing away from the display screen;

[0021] The middle portion of the unlocking handle is rotatably connected to the rear cover body;

[0022] One end of the unlocking handle extends to the side of the rear cover body facing the display screen, and is movably connected to one end of the unlocking latch facing away from the elastic limiting member.

[0023] In an optional design, the unlocking handle is rotatably connected to an end of the unlocking latch facing away from the elastic limiting member.

[0024] According to an embodiment of the second aspect of the present application, an electronic device is provided, comprising a display screen and a display screen back cover provided in any optional design method of the embodiment of the first aspect of the present application, wherein the display screen is arranged on the back cover body of the display screen back cover.

[0025] According to an embodiment of the third aspect of the present application, a vehicle-mounted display device is provided, comprising a display bracket and the electronic device provided by the embodiment of the second aspect of the present application, wherein one end of the display bracket is connected to the vehicle center console, and the other end of the display bracket has a ball head, which is used for detachable connection with the electronic device.

[0026] In an embodiment of the present application, a plurality of claws arranged in a circular pattern are provided on one side surface of the back cover body, and the plurality of claws form a locking portion. In this way, the inner surfaces of the plurality of claws can surround or encircle a spherical surface (that is, the inner surface of the locking portion is a spherical surface). The spherical surface can cooperate with the ball head on the display screen bracket, thereby facilitating the adjustment of the angle of the display screen, adapting to users of different heights and body shapes, and improving the user experience. In addition, an elastic limiter is sleeved on the outer surface of the locking portion. In this way, when the back cover of the display screen is installed on the ball head of the display screen bracket, the elastic limiter has a force on the multiple claws to retract inward (that is, pointing to the center of the ball head). Since the elastic limiter can provide different forces according to the size of its own deformation, that is to say, for display screens of different sizes or weights, the elastic limiter can adaptively adjust the size of the clamping force on the ball head. Compared with the existing technology, the clamping force on the ball head can be kept stable, thereby preventing the display screen from rotating downward when the vehicle shakes. Of course, when installing display screens of different sizes or different weights, due to the presence of the elastic limiter, a stable clamping force can be provided to the ball head, and downward rotation can be avoided, which can effectively improve the user experience.

[0046] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0048] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0050] In the description of this application, it should be understood that the terms "inside", "outside", "upper", "bottom", "front", "back" and the like indicate directions or positional relationships (if any) based on the attached Figure 1The orientation or positional relationship shown is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on this application.

[0051] In recent years, with the rapid development of science and technology, the diversification of transportation options has brought great convenience to people. As an important means of transportation, cars or vehicles occupy an important position in daily life.

[0052] With the gradual popularization of cars or vehicles, people have an increasing demand for vehicle intelligence during the use of vehicles. For example, the demand for intelligent networking of vehicles requires that vehicles not only realize basic auxiliary driving and entertainment functions such as navigation and music playback, but also require vehicles to be able to realize entertainment needs such as intelligent voice interaction or video playback. With the gradual realization of these demands, there are more and more display screens in the car, such as AR, HUD and digital instrument screens. Of course, in some examples, vehicle displays also include central control display, passenger entertainment screen and rear entertainment screen.

[0053] Typically, a vehicle's smart cockpit is equipped with an independent floating large screen (often also called a central control display), with a simple hollow design on the screen's bracket. However, such a floating large screen is usually fixed to the bracket, and the angle cannot be adjusted, making it unsuitable for passengers of different heights and body shapes.

[0054] Figure 1 is a structural diagram of a vehicle-mounted display device provided in an embodiment of the present application, Figure 2 is another structural diagram of the vehicle-mounted display device provided in an embodiment of the present application, Figure 3 It is along Figure 2 Sectional view along line AA.

[0055] Reference Figure 1-Figure 3 As shown, an embodiment of the present application provides a vehicle-mounted display device, which can be specifically applied to a vehicle center console, such as a central control display screen. Of course, in some possible examples, the vehicle-mounted display device can also be applied to the passenger seat and rear area of the vehicle (for example, set on the backrest of the front seat for use by rear passengers).

[0056] The vehicle-mounted display device includes an electronic device 10 and a display bracket 20, wherein one end of the display bracket 20 is connected to the vehicle (for example, connected to the center console of the vehicle or the backrest of the front seat), and the other end of the display bracket 20 is set as a ball head 21 (refer to Figure 3 shown) or spherical.

[0057] It should be noted that, in the embodiment of the present application, the display bracket 20 can be made of hard plastic. In some possible examples, the display bracket 20 can also be formed using a process such as slush molding. The periphery of the display bracket 20 can be wrapped with leather, velvet, etc. to enhance the overall texture of the display bracket 20.

[0058] Figure 4 It is a cross-sectional view of an electronic device provided in an embodiment of the present application.

[0059] Reference Figure 4 As shown, the embodiment of the present application further provides an electronic device 10, wherein a spherical groove (not numbered in the figure) is provided on the back side of the electronic device 10 (i.e., the side opposite to the display surface). When installing the electronic device 10, the ball head of the display bracket 20 can be inserted into the spherical groove, so that the display bracket 20 and the electronic device 10 are connected through a spherical pair. In this way, the electronic device 10 can be adjusted in various angles and directions to meet the usage requirements of different heights, body shapes, and different sitting postures of different passengers. This can enhance the user experience.

[0060] It is understandable that in the embodiment of the present application, the electronic device 10 may be a dedicated vehicle-mounted display screen 200, a central control screen, or a tablet computer, etc.

[0061] Specifically, the electronic device 10 may include a display screen 200 and a display screen back cover 100, with the display screen 200 disposed on one side of the display screen back cover 100. Typically, other electronic components, such as storage, a processor, a speaker, and a camera, may also be disposed in the space between the display screen 200 and the display screen back cover 100. It is understood that the electronic device 10 may be an electronic device 10 with a built-in battery, such as a built-in battery or a replaceable battery. In some possible examples, the electronic device 10 may also be connected to a vehicle power supply via a power cord connected to a power supply port.

[0062] The spherical groove may be specifically provided on the display screen back cover 100 .

[0063] In some specific application scenarios, for example, the electronic device 10 provided by an embodiment of the present application is mounted on a display screen holder 20 on a vehicle's center console. Typically, the front passenger or driver can adjust the display screen 200 to different angles by rotating it. However, rear passengers still have difficulty viewing the content displayed on the front display screen 200. In this case, the user can detach the electronic device 10 from the display screen holder 20 and directly hand it to the rear passenger, thereby improving the user experience for the rear passengers.

[0064] However, in actual use, although the angle of the electronic device 10 can be easily adjusted by connecting the electronic device 10 and the display bracket 20 via a spherical pair, when the electronic device 10 is adjusted to a certain angle and needs to be maintained at that angle, the angle of the electronic device 10 is maintained by the friction between the two spherical surfaces of the spherical pair. It is understood that friction is related to normal pressure and friction coefficient. For electronic devices 10 of different sizes or weights, the friction does not vary much, resulting in some electronic devices 10 being unable to maintain a certain angle, or the electronic device 10 rotating when the vehicle shakes, affecting the user experience and driving safety.

[0065] Figure 5 This is a structural diagram of a display screen back cover provided by an embodiment of the present application. Figure 5a This is a structural schematic diagram of the clamping claws in the back cover of the display screen provided in an embodiment of the present application.

[0066] Reference Figure 5 As shown, in order to solve the technical problems existing in the above-mentioned embodiments, the embodiment of the present application further provides a display screen back cover 100 , including: a back cover body 101 , and the back cover body 101 is used to connect with the display screen 200 .

[0067] Specifically, in the embodiment of the present application, the rear cover body 101 can be made of hard plastic, for example, by integral injection molding. In some possible examples, the rear cover body 101 can be square, rectangular, or other shapes. Of course, in other examples, such as when the electronic device 10 is a dedicated vehicle-mounted electronic device 10, the rear cover body 101 can also have a special-shaped structure (for example, a concave-convex shape or a gun-shaped shape) to avoid other structural components of the center console.

[0068] Continue to refer to Figure 5 As shown, the display screen back cover 100 provided in the embodiment of the present application further includes a locking portion 102 and an elastic stopper 103. The locking portion 102 is located on one side surface of the back cover body 101, and the locking portion 102 includes a plurality of claws 102a arranged in a circumference. The inner surface of the locking portion 102 is used to engage with the ball head 21 of the display screen bracket 20 (refer to FIG. Figure 3 shown) abutment.

[0069] Specifically, the plurality of claws 102a can be integrally formed with the rear cover body 101 on one side surface of the rear cover body 101. In some possible examples, the plurality of claws 102a can also be formed on one side surface of the rear cover body 101 by secondary injection molding. In other possible examples, the plurality of claws 102a and the rear cover body 101 can also be separated, for example, the plurality of claws 102a can be produced separately (for example, see Figure 5aAs shown, the claws 102a) and the rear cover body 101 can be produced separately first, and then the multiple claws 102a are fixed to the side surface of the rear cover body 101 by bolts, screws or screws.

[0070] It should be noted here that one side surface of the back cover body 101 may be the inner surface of the back cover body 101 (i.e., the surface of the back cover body 101 facing the display screen 200). In some possible examples, one side surface of the back cover body 101 may also be the outer surface of the back cover body 101 (i.e., the surface of the back cover body 101 facing away from the display screen 200).

[0071] Among them, reference Figure 5a As shown, the inner surfaces of the plurality of claws 102a (specifically, Figure 5a The surface along the positive x-direction side of the clamping portion 102) can be set to an arc shape; in some possible examples, the inner surface of the multiple clamping claws can also be a surface along the radial direction of the clamping portion 102 toward the axis of the clamping portion 102. After the multiple clamping claws 102a are arranged in a circle, the inner surfaces of the multiple clamping claws 102a can form a spherical surface (i.e., the inner surface of the clamping portion 102).

[0072] Specifically, the ball head 21 (refer to Figure 3 When the electronic device 10 is inserted into a plurality of circumferentially arranged claws 102a, the inner surfaces of the plurality of claws 102a respectively abut against the spherical surface of the ball head 21, so that a spherical pair is formed between the inner surfaces of the plurality of claws 102a (i.e., the inner surface of the engaging portion 102) and the spherical surface of the ball head 21, so that the electronic device 10 can be rotated to any angle relative to the ball head 21, which facilitates the adjustment of the angle of the electronic device 10.

[0073] The elastic limiting member 103 is sleeved on the outer surface of the engaging portion 102. The outer surface of the engaging portion 102 specifically refers to a surface on one side facing away from the axis of the engaging portion 102 along the radial direction of the engaging portion 102.

[0074] Specifically, in the embodiment of the present application, the elastic limiting member 103 may be in a ring-shaped or hemispherical shape. In some specific examples, the inner surface of the elastic limiting member 103 matches the shape of the outer surface of the engaging portion 102. For example, if the outer surface of the engaging portion 102 is formed into a cylindrical surface, the inner surface of the elastic limiting member 103 may also be a cylindrical surface.

[0075] In some specific examples, the elastic limiting member 103 can be a silicone ring, a rubber ring, a silicone leather case, or a rubber leather case.

[0076] It can be understood that when the ball head 21 (refer to Figure 3When the ball head 21 is squeezed between the multiple claws 102a, the multiple claws 102a will expand outward. In the embodiment of the present application, an elastic limiter 103 is sleeved on the outer surface of the multiple claws 102a. When the multiple claws 102a expand outward, they will be constrained by the elastic limiter 103. That is to say, the elastic limiter 103 will provide the multiple claws 102a with a tendency to tighten inward, thereby providing corresponding spherical pair friction for electronic devices 10 of different sizes or weights.

[0077] In the embodiment of the present application, a plurality of claws 102a arranged in a circumferential pattern are provided on one side surface of the rear cover body 101, and the plurality of claws 102a form a clamping portion 102. In this way, the inner surfaces of the plurality of claws 102a can surround or surround a spherical surface (that is, the inner surface of the clamping portion 102 is a spherical surface), and the spherical surface can be aligned with the ball head 21 on the display bracket 20 (refer to FIG. Figure 3 As shown), the angle of the display screen 200 can be adjusted conveniently, so as to adapt to users of different heights and body shapes and enhance the user experience. In addition, an elastic limiter 103 is sleeved on the outer surface of the locking portion 102. In this way, when the display screen back cover 100 is installed on the ball head 21 of the display screen bracket 20, the elastic limiter 103 has an inward force on the multiple claws 102a (i.e., pointing to the center of the ball head 21). Since the elastic limiter 103 can provide different forces according to the size of its own deformation, that is, for display screens 200 of different sizes or weights, the elastic limiter 103 can adaptively adjust the size of the clamping force on the ball head 21. Compared with the prior art, the clamping force on the ball head 21 can be kept stable, thereby preventing the display screen 200 from rotating downward when the vehicle shakes. Of course, when installing display screens 200 of different sizes or different weights, due to the presence of the elastic limiter 103, a stable clamping force can be provided to the ball head 21, and downward rotation can also be avoided, which can effectively improve the user experience.

[0078] Figure 6 It is a structural schematic diagram of the elastic limiting member in the back cover of the display screen provided in an embodiment of the present application.

[0079] Reference Figure 5 and Figure 6 As shown, in an optional example of an embodiment of the present application, the elastic limiting member 103 is a limiting retaining spring, which includes a spring coil 1031 and at least one extension portion 1032. The spring coil 1031 is sleeved on the outer surface of the locking portion 102; the at least one extension portion 1032 is located at the opening 1033 of the spring coil 1031, and the extension portion 1032 extends radially outward along the spring coil 1031.

[0080] Specifically, in the embodiment of the present application, the position-limiting retaining spring can be formed by winding or bending a steel sheet. It is understood that, generally, the spring coil 1031 of the position-limiting retaining spring has an opening 1033, which allows the spring coil 1031 to undergo a certain deformation in the radial direction, thereby providing elastic force to the multiple claws 102a.

[0081] Among them, reference Figure 6 As shown, at least one extension portion 1032 is provided at the opening 1033 of the spring coil 1031. The extension portion 1032 can extend along the radial direction of the spring coil 1031 (for example, Figure 6 In a specific configuration, the extension portion 1032 and the spring coil 1031 can be integrally formed. For example, the spring coil 1031 and the extension portion 1032 can be formed by bending a steel sheet as described above.

[0082] In this way, when it is necessary to remove the electronic device 10 from the display screen support 20 (refer to Figure 3 When removing the electronic device 10 from the display bracket 20, the user can manually move the extension portion 1032 to expand the spring coil 1031 outward to reduce the elastic force of the spring coil 1031 on the multiple claws 102a, thereby reducing the friction between the multiple claws 102a and the ball head 21, and conveniently removing the electronic device 10 from the display bracket 20.

[0083] Continue to refer to Figure 6 As shown, in an optional design of the embodiment of the present application, an extension portion 1032 may be provided at both ends of the spring coil 1031. In other words, two extension portions 1032 may be provided at the opening 1033 of the spring coil 1031, and the two extension portions 1032 are arranged opposite to each other.

[0084] It can be understood that, since the extension portions 1032 all extend radially outward along the spring coil 1031, Figure 6 As shown, there is a certain angle between the two extensions 1032. That is, the extension lines of the two extensions 1032 intersect at the axis of the spring coil 1031 to form a "V" shape structure. In this way, when the user needs to remove the electronic device 10 from the display bracket 20 (refer to Figure 3 When it is disassembled, it can be removed outwards (for example Figure 6 The two extensions 1032 are moved in the direction indicated by x-x' in the middle, so that the spring coil 1031 expands outward under the drive of the extension 1032, thereby reducing the elastic force of the spring coil 1031 on the multiple claws 102a, and the electronic device 10 can be easily removed from the display bracket 20.

[0085] Figure 7 This is another structural schematic diagram of the display screen back cover provided in an embodiment of the present application.

[0086] Reference Figure 7 As shown, in an example of an embodiment of the present application, the display screen back cover 100 further includes an unlocking latch 104 , which is movably provided on the back cover body 101 and is located radially outside the opening 1033 along the spring coil 1031 .

[0087] It is understandable that the unlocking latch 104 and the elastic limiting member 103 are located on the same side of the rear cover body 101. For example, when the elastic limiting member 103 is located on the outer surface of the rear cover body 101, the unlocking latch 104 is also located on the outer surface of the rear cover body 101.

[0088] The unlocking latch 104 may be slidably connected to the rear cover body 101; for example, it may move along the surface of the rear cover body 101. In some possible examples, the unlocking latch 104 may also be rotatably connected to the rear cover body 101; for example, a mounting base is provided on the surface of the rear cover body 101, and the unlocking latch 104 is connected to the mounting base via a rotating shaft.

[0089] The width of the unlocking latch 104 is greater than the width of the opening 1033. Figure 7 As shown, in the embodiment of the present application, the width of the unlocking latch 104 is Figure 7 When the unlocking pin 104 moves on the rear cover body 101 (e.g., slides along the surface of the rear cover body 101 or rotates relative to the rear cover body 101), at least a portion of the unlocking pin 104 (e.g., the end of the unlocking pin 104) can be inserted into the opening 1033, thereby expanding the opening 1033.

[0090] For example, refer to Figure 7 As shown, when the unlocking latch 104 is along Figure 7 When the z direction moves downward, the end of the unlocking latch 104 (eg Figure 7 The lower end of the spring coil 1031 is inserted into the opening 1033. Since the width of the unlocking pin 104 is greater than the width of the opening 1033, the opening 1033 gradually expands outward during the insertion of the unlocking pin 104, thereby reducing the tightening force of the spring coil 1031 on the multiple claws 102a, reducing the friction between the multiple claws 102a and the ball head, and facilitating the disassembly of the electronic device.

[0091] Figure 8 yes Figure 7 A partial enlarged view of point B in the middle. Figure 7 and Figure 8 As shown, in an optional example, the end of the unlocking pin 104 facing the elastic limiting member 103 is tapered.

[0092] In order to save the space occupied by various components and reduce the thickness of the back cover of the display screen, that is, to reduce the thickness of the electronic device, and realize the light and thin design of the electronic device, the unlocking latch 104 can be designed as a thin sheet or plate structure. In order to facilitate the unlocking latch 104 to be smoothly inserted into the opening 1033, in the embodiment of the present application, a chamfer or rounded corner is provided at one end of the unlocking latch 104 facing the elastic limiter 103, so that the end of the unlocking latch 104 forms a cone, that is, along the width direction of the unlocking latch 104 (for example, Figure 7 or Figure 8 The two sides of the unlocking latch 104 are formed with inclined surfaces relative to the length direction (eg, Figure 7 The z direction or Figure 8 In addition, the inclined surface makes the width of the unlocking latch 104 Figure 7 or Figure 8 The lower part gradually decreases.

[0093] In this way, along Figure 7 The z direction or Figure 8 In the y direction, the width of the lower end of the unlocking pin 104 gradually increases. When inserting the unlocking pin 104 into the middle opening 1033, the end with a smaller width is first inserted into the opening 1033, and then the insertion of the unlocking pin 104 is locked. The width of the unlocking pin 104 gradually increases, thereby gradually expanding the opening 1033 outward, which can facilitate the insertion of the unlocking pin 104.

[0094] Figure 9 This is a schematic structural diagram of the back cover body in the display screen back cover provided in an embodiment of the present application.

[0095] Reference Figure 7-Figure 9 As shown, in an optional design, for example, when the unlocking latch 104 moves along the surface of the rear cover body 101, a latch limiter 105 is provided on the rear cover body 101. The latch limiter 105 is located radially outside the opening 1033 along the spring coil 1031. A limiting groove radially along the spring coil 1031 is formed between the latch limiter 105 and the rear cover body 101, and the unlocking latch 104 is located in the limiting groove.

[0096] Specifically, the latch stopper 105 can be two oppositely disposed L-shaped structural members. In a specific configuration, the latch stopper 105 can be integrally formed with the rear cover body 101. In some possible examples, the latch stopper 105 can also be obtained by secondary injection molding.

[0097] In this way, when the unlocking latch 104 moves on the surface of the rear cover body 101, it can move along the limiting groove, which can limit the moving direction of the unlocking latch 104 and avoid interference with other components caused by the movement of the unlocking latch 104.

[0098] When using it specifically, refer to Figure 8 As shown, users can use their fingers to move along Figure 8 Push the unlocking latch 104 in the negative direction of the middle y axis, and the unlocking latch 104 moves downward (to Figure 8 As an example), the end of the unlocking pin 104 is inserted into the opening 1033 and the buckle is expanded outward, thereby facilitating the disassembly of the electronic device.

[0099] In an alternative design approach, continue to refer to Figure 8 and Figure 9 As shown, a latch guide 106 is further provided on the rear cover body 101 , and the latch guide 106 is located at the opening 1033 of the spring coil 1031 .

[0100] Specifically, the latch guide 106 may be multiple, and the multiple guides are arranged along the width direction of the unlocking latch 104 (for example, Figure 8 The latch guides 106 protrude from the surface of the rear cover body 101 .

[0101] In specific configuration, the latch guide 106 can be configured in the same or similar manner as the aforementioned latch stopper 105. For example, the latch guide 106 is integrally formed with the rear cover body 101, or the latch guide 106 is formed on the surface of the rear cover body 101 by secondary injection molding.

[0102] The latch guide 106 has a guide plane 1061 , which extends along the moving direction of the unlocking latch 104 . The unlocking latch 104 selectively moves along the guide plane 1061 .

[0103] In this way, when the unlocking latch 104 moves, it is lifted by the latch guide 106, which can reduce the contact area between the unlocking latch 104 and the back cover body 101, that is, it can reduce the friction between the unlocking latch 104 and the back cover body 101, making it easier for the electronic device 10 to be connected to the display bracket 20 (see FIG. Figure 3 The disassembly between the two devices (as shown) improves the user experience.

[0104] Figure 10 This is a schematic structural diagram of a limiting ring in a display screen back cover provided in an embodiment of the present application.

[0105] Reference Figure 8 and Figure 10As shown, in order to prevent the opening 1033 from being expanded too much when disassembling the electronic device, which would make it difficult for the elastic limiting member 103 to recover from deformation, in the embodiment of the present application, a limiting ring 107 is provided on the outer periphery of the elastic limiting member 103. The limiting ring 107 and the elastic limiting member 103 are clearance-fitted.

[0106] In other words, there is a certain reserved gap between the inner surface of the limiting ring 107 and the outer surface of the elastic limiting member 103. In this way, when the elastic limiting member 103 is expanded outward, the reserved gap can provide an escape position for the elastic limiting member 103, so that the elastic limiting member 103 has a certain displacement space.

[0107] When the elastic limit member 103 expands outward to a certain extent, the outer surface of the elastic limit member 103 contacts or presses against the inner surface of the limit ring 107, and the elastic limit member 103 cannot expand further, thereby limiting the expansion range of the elastic limit member 103, avoiding the situation where the elastic limit member 103 over-expands and cannot recover, and ensuring the effectiveness of the elastic limit member 103 in tightening the multiple claws 102a.

[0108] Among them, reference Figure 10 As shown, the limiting ring 107 has an escape opening 1071 , and the extension portion 1032 extends from the escape opening 1071 to the outside of the limiting ring 107 .

[0109] In a specific configuration, the limiting ring 107 and the claw 102a can be integrally formed, for example, the limiting ring 107 and the claw 102a are integrally molded into one part. A limiting groove is left between the limiting ring 107 and the claw 102a, and the elastic limiting member 103 can be disposed in the limiting groove.

[0110] Of course, in some possible examples, the limiting ring 107 and the claw 102 a may also be formed on the surface of the rear cover body 101 .

[0111] Reference Figure 4 and Figure 5 As shown, in an optional design, the back cover body 101 has a through hole 1011 , the locking portion 102 is located on the side of the back cover body 101 facing the display screen 200 , and a plurality of claws 102a are arranged circumferentially around the through hole 1011 .

[0112] In this way, the claws 102a, the elastic limiter 103 and other components can be stored and hidden in the rear cover body 101, which can protect the limit claws 102a and the elastic limiter 103 and other components and prevent them from being damaged during transportation. In addition, it can also make the appearance of the entire electronic device neat and simple, and improve the appearance of the electronic device.

[0113] It is understandable that, referring to Figure 4 As shown, after the claws 102a, the elastic limiting member 103, etc. are arranged inside the electronic device 10, when the electronic device 10 needs to be removed from the display bracket 20 (refer to Figure 3 When the electronic device 10 is removed from the rear cover 101 (as shown), it is inconvenient to operate the unlocking latch 104. In some possible examples, at least a portion of the unlocking latch 104 can be extended to the outside of the rear cover body 101. For example, the end of the unlocking latch 104 facing away from the elastic stopper 103 can extend from the side wall of the electronic device 10 to the outside of the electronic device 10. The user presses the end of the unlocking latch 104 to move the unlocking latch 104 toward the elastic stopper 103.

[0114] In some possible examples, the unlocking latch 104 may be configured to be L-shaped, with a portion of the unlocking latch 104 extending from the rear cover body 101 to the outside of the rear cover body 101. When unlocking is required, the user moves the unlocking latch 104 by pulling the L-shaped handle of the unlocking latch 104.

[0115] To facilitate the operation of the unlocking latch 104, refer to Figure 4 As shown, in an optional example, an unlocking handle 108 is provided on the upper cover body, and the unlocking handle 108 is located on the side of the rear cover body 101 facing away from the display screen 200; the middle portion of the unlocking handle 108 is rotatably connected to the rear cover body 101. Specifically, it can be rotatably connected to the rear cover body 101 via a rotating shaft.

[0116] One end of the unlocking handle 108 extends to the side of the rear cover body 101 facing the display screen 200 , and is movably connected to one end of the unlocking latch 104 facing away from the elastic limiting member 103 .

[0117] That is, the unlocking handle 108 rotates around the rotating shaft between the rear cover body 101 to form a lever, and the end of the unlocking handle 108 extending to the inner side of the rear cover body 101 pushes the unlocking pin 104 to move toward the elastic limiter 103.

[0118] For example, refer to Figure 4 As shown, when the unlocking handle 108 is moved upward ( Figure 4 x1 direction in the figure), the end of the unlocking handle 108 pushes the unlocking latch 104 downward ( Figure 4 y1 direction in FIG), so that the unlocking pin 104 is inserted into the opening 1033, and the electronic device 10 can be easily removed from the display bracket 20.

[0119] Figure 11 This is a schematic diagram of the assembly structure of the unlocking handle and the unlocking latch in the back cover of the display screen provided in an embodiment of the present application.

[0120] For some possible examples, continue with Figure 4 As shown, the end of the unlocking handle 108 located outside the rear cover body 101 is parallel or approximately parallel to the surface of the rear cover body 101. Figure 11 As shown, the cross section of the unlocking handle 108 can be a V-shaped structure. In this way, it is easy to store the unlocking handle 108 and reduce the space occupied by the unlocking handle 108 along the thickness direction of the rear cover body 101.

[0121] Continue to refer to Figure 11 As shown, in an optional design, the unlocking handle 108 is rotatably connected to the end of the unlocking latch 104 facing away from the elastic limiting member 103 .

[0122] Specifically, a rotating shaft can be provided at the end of the unlocking handle 108 extending to the inner side of the rear cover body 101, and the end of the unlocking latch 104 facing away from the elastic stopper 103 is rotatably connected to the unlocking handle 108 via the rotating shaft. In this way, the connection between the unlocking handle 108 and the unlocking latch 104 is more stable, and the linkage is more stable.

[0123] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
