Description

Technical Field

[0001] The present application relates to the field of mechanics, and in particular to a detachable cover assembly and a terminal device. Background Art

[0002] Existing terminal devices are usually equipped with a cover plate, such as a logo cover plate. Figure 1 It is a partial schematic diagram of a terminal device with a cover plate installed in the prior art. Figure 2 yes Figure 1 A partial cross-sectional view of the terminal device with the cover plate installed is shown in FIG. Figure 1 and Figure 2 As shown, a cover plate 2 is installed on the terminal device 1. In some production and life scenarios, it may be necessary to remove the cover plate from the terminal device.

It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Utility Model Content

[0004] The inventors found that in the prior art, for example Figure 1 and Figure 2 As shown, after the cover plate 2 is installed on the terminal device 1, only the outer cover surface of the cover plate 2 is exposed to the operating environment, and the cover plate fits well with the terminal device. Therefore, the staff needs to use tools 3 (such as a screwdriver or other tools specifically used to remove the cover plate) to remove the cover plate 2 from the terminal device 1.

[0005] Furthermore, if the staff does not carry the appropriate tools, they will not be able to remove the cover in time, or they will need to find the appropriate tools before removing the cover, which will affect work efficiency. In addition, since the staff need to carry tools frequently, the tools may be lost, which is not conducive to saving tool management.

[0006] In order to solve at least one of the above problems or other similar problems, an embodiment of the present application provides a detachable cover plate assembly, the cover plate assembly comprising a cover plate and a body on which the cover plate is mounted;

[0048] The implementation of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0049] The embodiment of the present application provides a detachable cover plate assembly. Figure 3 FIG. 1 is a schematic diagram of a detachable cover assembly according to an embodiment of the present application. Figure 1 As shown, the cover plate assembly includes a cover plate 100 and a body 200 on which the cover plate is mounted. The body 200 may be, for example, a terminal device or a part of a terminal device on which the cover plate 100 is mounted, or the body 200 may be a component independent of the terminal device, which is not limited in the present application.

[0050] First, the structure of the cover plate 100 will be described below.

[0051] Figure 4 is a schematic diagram of a cover plate of an embodiment of the present application, Figure 5 is a side view of the cover plate of the embodiment of the present application. Figure 4 and Figure 5 As shown, the cover plate 100 includes an outer cover 101, a first elastic deformation portion 102, a second elastic deformation portion 103 and a pressing operation portion 104 which are sequentially connected along a first direction X, and a first clamping portion 105 is provided on the surface of the first elastic deformation portion 102. The outer cover 101, the first elastic deformation portion 102, the second elastic deformation portion 103, the pressing operation portion 104 and the first clamping portion 105 are integrally formed.

[0052] The first elastic deformation part 102 and the second elastic deformation part 103 can generate elastic deformation when subjected to a force, and restore the shape after the force disappears; when the second elastic deformation part 103 is deformed, it can drive the pressing operation part 104 connected thereto to move in a preset direction, for example, along Figure 5 The movement is in the direction indicated by the arrow A shown.

[0053] During the installation of the cover plate 100, the first elastic deformation portion 102 and the second elastic deformation portion 103 will be elastically deformed, so that the cover plate 100 enters the preset position of the body 200 and is fixed to the body 200. At this time, at least a part of the pressing operation portion 104 of the cover plate 100 is exposed through the opening on the body 200, so that the staff can directly contact the pressing operation portion 104. During the removal of the cover plate 100, the staff can directly press the pressing operation portion 104 to apply a force, so that the cover plate 100 is deformed and detached from the body 200, and the cover plate can be removed without using tools, which is conducive to improving work efficiency and saving tool management work.

[0054] In some embodiments, Figure 4 and Figure 5 As shown, the first elastic deformation portion 102 includes a curved portion 1021 and a vertical portion 1022 .

[0055] The first end of the curved portion 1021 is fixedly connected to the outer cover 101, the second end of the curved portion 1021 is fixedly connected to the first end of the vertical portion 1022, and the second end of the vertical portion 1022 is fixedly connected to the second elastic deformation portion 103. At least the curved portion 1021 can generate elastic deformation when subjected to a force. For example, Figure 5 As shown in FIG. 1 , when the bending portion 1021 itself is subjected to a force in the second direction Y, the bending portion 1021 can elastically deform in the direction indicated by the arrow B; for another example, when the vertical portion 1022 of the first elastic deformation portion 102 is subjected to a force in the second direction Y, the bending portion 1021 can also elastically deform in the direction indicated by the arrow B. When the force applied to the first elastic deformation portion 102 disappears, the first elastic deformation portion 102 can return to its original position. Figure 5 This embodiment is described by taking the case where the first elastic deformation portion 102 is subjected to a force in the second direction Y and the first elastic deformation portion 102 is elastically deformed in the direction indicated by the arrow B as an example. In fact, the force on the first elastic deformation portion 102 may also be a force in a direction other than the second direction Y, and the direction in which the first elastic deformation portion 102 is elastically deformed may also be different from the second direction Y. Figure 5 The direction indicated by the arrow B is not limited in this application.

[0056] In some embodiments, the first engaging portion 105 is disposed on the surface of the vertical portion 1022. Figure 5 As shown, the first engaging portion 105 is disposed on a side surface of the vertical portion 1022 of the first elastic deformation portion 102 and protrudes from the vertical portion 1022 .

[0057] In some embodiments, the thickness of the second elastic deformation portion 103 is smaller than the thickness of the first elastic deformation portion 102 and the thickness of the pressing operation portion 104. Figure 5 As shown, the thickness of the second elastic deformation part 103 is significantly smaller than the thickness of the first elastic deformation part 102 connected thereto and the thickness of the pressing operation part 104. Therefore, when one of the first elastic deformation part 102 and the pressing operation part 104 is subjected to a force, or when the first elastic deformation part 102 and the pressing operation part 104 are simultaneously subjected to forces in different directions, the second elastic deformation part 103 will bend due to its thin thickness, thereby causing the first elastic deformation part 102 and the pressing operation part 104 to move relative to each other.

[0058] In some embodiments, the pressing operation portion 104 includes a pressing surface.

[0059] For example, Figure 5 As shown, the pressing operation part 104 includes a pressing surface 1041. After the cover 100 is installed on the main body 200, the pressing surface 1041 of the pressing operation part 104 is exposed through an opening on the main body 200. Thus, a staff member can apply a force to the pressing operation part 104 through the pressing surface 1041 to make the cover 100 detach from the main body 200, and the cover 100 can be disassembled without tools.

[0060] In some embodiments, an anti-slip structure is disposed on the pressing surface 1041 .

[0061] For example, Figure 5 As shown, a plurality of anti-skid structures 1042 are provided on the pressing surface 1041. The anti-skid structures 1042 are, for example, convex structures provided on the pressing surface 1041. The anti-skid structures 1042 can be in various shapes, such as strips, particles, etc. Thus, the friction force when the worker presses the pressing surface 1041 can be increased to avoid slipping, thereby making it easier to remove the cover plate 100 from the body 200.

[0062] In some embodiments, the anti-slip structure 1042 can be integrally formed with the pressing operation part 104; or, the anti-slip structure 1042 can be a structure independent of the pressing surface 1041 of the pressing operation part 104, for example, the anti-slip structure 1042 is adhered to the pressing surface 1041 by an adhesive.

[0063] In some embodiments, the pressing operation portion 104 includes a guide arc surface, which can guide the pressing operation portion 104 to move during the disassembly process of the cover plate 100. Figure 5As shown, the pressing operation part 104 includes a guiding arc surface 1043. During the process of removing the cover plate 100, the pressing operation part 104 may come into contact with the structure of the main body 200. If there is no guiding arc surface 1043, for example, if the guiding arc surface 1043 is replaced by a plane parallel to the second direction Y, the pressing operation part 104 is easily stuck by the main body 200, so that the cover plate 100 cannot be smoothly removed from the main body 200, and tools may still be needed at this time. In the case where the guiding arc surface 1043 is provided on the pressing operation part 104, even if the pressing operation part 104 comes into contact with the structure of the main body 200, it can move along the guiding arc surface 1043 to the left direction indicated by the arrow A, so that the cover plate 100 can be smoothly removed from the main body 200.

[0064] In some embodiments, the cover plate 100 further includes a limiting portion, which is disposed on a side surface of the outer cover 101 connected to the first elastic deformation portion 102 .

[0065] For example, Figure 4 As shown, the cover plate 100 includes a limiting portion 106, which is arranged in parallel with the first elastic deformation portion 102. The number of the limiting portion 106 can be one or more, for example Figure 4 Two limiting parts 106 are shown in FIG. Thus, during the process of installing and removing the cover plate 100, the position of the cover plate 100 relative to the body 200 can be limited to prevent the cover plate 100 from deviating from the position and failing to be smoothly installed on or removed from the body 200.

[0066] The following embodiments illustrate the structure of the main body 200 .

[0067] Figure 3 shows a three-dimensional structural diagram of the body 200, Figure 6 : is a side view of the body of the embodiment of the present application, such as Figure 3 and Figure 6 As shown, the body 200 includes at least one receiving portion 201 capable of receiving the cover plate, and one receiving portion 201 corresponds to one cover plate 100; wherein the receiving portion 201 is surrounded by the body 200 and has openings on at least two sides thereof, so that the cover plate 100 can enter. The receiving portion 201 includes a first opening 2011, a first guiding inclined surface 2012 (shown by black bold lines), a second opening 2013, and a second engaging portion 2014.

[0068] The first opening 2011 is formed on the first surface of the receiving portion 201 , and the cover plate 100 can enter or leave the receiving portion 201 through the first opening 2011 .

[0069] The first guiding inclined surface 2012 is disposed in the receiving portion 201 and is opposite to the first opening 2011, and can guide the pressing operation portion 104 of the cover plate 100 entering the receiving portion 201 to move in a preset first deformation direction; wherein the preset first deformation direction is, for example, Figure 5 After the cover plate 100 enters the accommodating portion 201 from the first opening 2011, the pressing operation portion 104 contacts the first guiding inclined surface 2012, and as the cover plate 100 continues to move downward, the pressing operation portion 104 is subjected to force, thereby deforming the second elastic deformation portion 103, driving the pressing operation portion 104 to move in the first deformation direction, so that the cover plate 100 can continue to move downward. Figure 7 is another schematic diagram of the cover assembly of an embodiment of the present application, Figure 7 The position of the first guiding slope 2012 is marked in Figure 7 The structure shown in the black dashed box in the lower center.

[0070] The second opening 2013 is provided on the second surface of the accommodating portion 201 adjacent to the first surface, and exposes the pressing surface 1041 of the pressing operating portion 104 after it moves in the first deformation direction. As mentioned above, after the pressing operating portion 104 moves in the first deformation direction, as the cover plate 100 continues to move downward, the pressing operating portion 104 moves toward the second opening 2013 along the first guiding inclined surface 2012. After the cover plate 100 is completely installed on the body 200, the pressing surface 1041 of the pressing operating portion 104 can be exposed through the second opening 2013, and the staff can directly contact the pressing surface 1041 and apply force to it.

[0071] The second engaging portion 2014 is disposed on the second surface of the receiving portion 201, that is, the surface having the second opening 2013. The second engaging portion 2014 can engage with the first engaging portion 105 of the cover plate 100 to fix the cover plate 100. For example, after the cover plate 100 reaches a suitable position in the receiving portion 201, the first engaging portion 105 of the cover plate 100 is located at Figure 6 The lower edge of the second snap-fitting portion 2014 is shown. At this time, the first elastic deformation portion 102 of the cover plate 100 is in a state of slight elastic deformation or a state of no elastic deformation. Thus, the first snap-fitting portion of the cover plate 100 can snap-fit ​​with the second snap-fitting portion 2014 of the accommodating portion 201, thereby fixing the cover plate 100 to prevent the cover plate 100 from falling out of the accommodating portion 201, thereby achieving fixed installation of the cover plate 100 and the main body 200.

[0072] In some embodiments, Figure 6As shown, the receiving portion 201 further includes a second guiding inclined surface 2015 (shown by a black bold line), which is arranged on the inner side of the second surface of the receiving portion 201 and opposite to the first opening 2011, and can guide the pressing operation portion 104 of the cover plate 100 entering the receiving portion 201 to move in a preset second deformation direction. The preset second deformation direction is, for example, Figure 5 After the cover plate 100 enters the accommodating portion 201 from the first opening 2011, the pressing operation portion 104 first contacts the second guiding inclined surface 2015, and as the cover plate 100 continues to move downward, the pressing operation portion 104 is subjected to force, thereby deforming the second elastic deformation portion 103, driving the pressing operation portion 104 to move in the second deformation direction, so that the cover plate 100 can continue to move downward.

[0073] In some embodiments, Figure 3 and Figure 7 As shown, the accommodating portion 201 further includes a limiting groove 2016 ( Figure 7 ), which is arranged in the accommodating portion 201 and matches the shape and size of the limiting portion 106 of the cover plate 100. Figure 7 The limit portion 106 (i.e. Figure 7 The structure shown in the two three-dimensional dotted frames above) and the limiting groove 2016 of the body 200 (i.e. Figure 7 Thus, during the process of installing and removing the cover plate 100, the relative movement between the cover plate 100 and the receiving portion 201 in a direction perpendicular to the first direction X can be restricted, thereby preventing the cover plate 100 from deviating from a preset installation or removal track, and ensuring that the cover plate 100 is smoothly installed on the body 200 or smoothly removed from the body 200.

[0074] The above embodiments respectively describe the structures of the cover plate 100 and the body 200 of the detachable cover plate assembly of the present application. Next, the installation process and the removal process of the cover plate 100 and the body 200 are described to illustrate the installation and removal principles of the cover plate 100 and the body 200.

[0075] Figures 8 to 17 FIG. 1 is a schematic diagram of the installation process of the cover assembly of the embodiment of the present application. Figures 8 to 17 As shown, when the cover plate 100 is installed, the movement process of the cover plate 100 is as follows:

[0076] Step 1: See Figure 8 , align the cover plate 100 with the first opening 2011 of the receiving portion 201 of the body 200, and move downward (along the first direction X). Figure 8 Although not shown, the limiting portion 106 of the cover plate 100 is also aligned with the limiting groove 2016 of the receiving portion 201. Figure 8 It can be seen that at this time, in the first direction X, the pressing operation portion 104 of the cover 100 and the second engaging portion 2014 of the receiving portion 201 of the body 200 at least partially overlap.

[0077] Step 2: See Fig. 9 The cover plate 100 continues to move downward until the pressing surface 1041 of the pressing operation portion 104 contacts the second guide inclined surface 2015 of the second engaging portion 2014 (eg Fig. 9 At this time, the pressing operation portion 104 is subjected to force, and the second elastic deformation portion 103 is about to undergo elastic deformation and drive the pressing operation portion 104 along Fig. 9 The device moves in the direction indicated by the arrow (the second deformation direction).

[0078] Step 3: See Fig.10 The pressing operation portion 104 of the cover plate 100 moves in the second deformation direction, and as the cover plate 100 moves downward, the pressing operation portion 104 continues to move downward in close contact with the surface of the second engaging portion 2014 (eg, Fig.10 black dots and gray lines).

[0079] Step 4: See Fig.11 As the cover plate 100 continues to move downward, when the pressing operation part 104 moves downward to a suitable position, the guiding arc surface 1043 of the pressing operation part 104 begins to contact the second engaging part 2014. As the cover plate 100 continues to move downward, the second elastic deformation part 103 begins to restore its shape, and at the same time drives the pressing operation part 104 to move along the Fig.11 The guide arc surface 1043 will also begin to move close to the second engaging portion 2014 (such as Fig.11 black dots and grey lines).

[0080] Step 5: See Fig.12 As the cover plate 100 continues to move downward, the pressing operation portion 104 completely passes over the second engaging portion 2014, and the second elastic deformation portion 103 completely recovers its shape. At this time, the vertical portion 1022 of the first elastic deformation portion 102 of the cover plate 100 is in close contact with the second engaging portion 2014 (such as Fig.12 denoted by the black line).

[0081] Step 6: See Fig.13 As the cover plate 100 continues to move downward, the pressing operation portion 104 begins to contact the first guide slope 2012 (eg Fig.13 At this time, the second elastic deformation part 103 is about to undergo elastic deformation and drive the pressing operation part 104 to move along Fig.13 The device moves in the direction indicated by the arrow (the second deformation direction).

[0082] Step 7: See Fig.14 As the cover plate 100 continues to move downward, the pressing operation portion 104 is subjected to the force of the first guide slope 2012, and the second elastic deformation portion 103 begins to elastically deform and drives the pressing operation portion 104 to move along Fig.14 The device moves in the direction indicated by the arrow below (the first deformation direction);

[0083] Furthermore, as the cover plate 100 continues to move downward, the first engaging portion 105 disposed on the vertical portion 1022 begins to contact the second engaging portion 2014 (eg, Fig.14 Then, the first elastic deformation portion 102 (mainly the vertical portion 1021) begins to move along Fig.14 The elastic deformation occurs in the direction indicated by the arrow above. It should be noted that there is enough space in the accommodating portion 201 to allow the first elastic deformation portion 102 of the cover plate 100 and the first clamping portion 105 provided on the first elastic deformation portion 102 to enter at the same time. However, due to the limiting effect of the limiting portion 106 of the cover plate 100 and the limiting groove 2016 of the accommodating portion 201, when the first elastic deformation portion 102 does not undergo elastic deformation, the first elastic deformation portion 102 moves closely against the second clamping portion 2014, and when the first elastic deformation portion 102 undergoes elastic deformation, the first clamping portion 105 can enter the accommodating portion 201 together with the first elastic deformation portion 102.

[0084] Step 8: See Fig.15 As the cover plate 100 continues to move downward, the pressing operation portion 104 continues to be subjected to the force of the first guide slope 2012, and the second elastic deformation portion 103 elastically deforms and drives the pressing operation portion 104 to move along Fig.15 The movement continues in the direction indicated by the arrow (the first deformation direction);

[0085] At the same time, the bending portion 1021 of the first elastic deformation portion 102 begins to move along Fig.14 The first engaging portion 105 and the second engaging portion 2014 are in contact with each other (eg, Fig.15 black dots).

[0086] Step 9: See Fig.16 As the cover plate 100 continues to move downward, the bent portion 1021 of the first elastic deformation portion 102 continues to elastically deform, and the first engaging portion 105 enters the accommodating portion 201 together with the first elastic deformation portion 102, and the first engaging portion 105 is closely attached (such as Fig.16 The second engaging portion 2014 moves downward. At this time, the pressing operation portion 104 is driven by the second elastic deformation portion 103 to move along the Fig.16Move in the direction indicated by the arrow below.

[0087] Step 10: See Fig.17 As the cover plate 100 continues to move downward, the first engaging portion 105 moves downward to a suitable position. As the cover plate 100 continues to move downward, the curved portion 1021 of the first elastic deformation portion 102 gradually recovers its shape. Fig.16 When the first elastic deformation part 102 gradually moves to the lower side of the second engaging part 2014 in the direction of the upper arrow, the first elastic deformation part 102 completely recovers its shape. Thus, the first engaging part 105 and the second engaging part 2014 are engaged, and at this time, the cover plate 100 cannot be separated from the receiving part 201.

[0088] At the same time, the second elastic deformation portion 103 maintains the elastic deformation state, and as the shape of the first elastic deformation portion 102 is restored, the pressing operation portion 104 moves to the Fig.17 Move slightly in the direction of the arrow and keep Fig.17 At this time, the pressing surface 1041 of the pressing operation portion 104 is exposed through the second opening 2013 of the accommodating portion 201 .

[0089] At this point, the cover plate 100 and the body 200 are fixedly installed.

[0091] Step 11: See Fig.18 The pressing surface 1041 of the pressing operation unit 104 is pressed by the hand of the staff. Fig.18 At this time, the first elastic deformation portion 102 (mainly the bending portion 1021) of the cover plate 100 is about to undergo elastic deformation.

[0092] Step 12: See Fig.19 , staff applied Fig.18 After the force shown, the first elastic deformation portion 102 (mainly the bending portion 1021) of the cover plate 100 is elastically deformed until the first engaging portion 105 disposed on the first elastic deformation portion 102 is offset from the second engaging portion 2014 of the receiving portion 201 (as shown in FIG. Fig.19 ), and the cover plate 100 moves upward until the first engaging portion 105 is no longer engaged with the second engaging portion 2014.

[0093] Step 13: See Fig. 20 As the cover plate 100 moves upward, the pressing operation portion 204 retracts into the accommodating portion 201 (eg Fig. 20 As shown by the black line, a large gap appears between the outer cover 101 of the cover plate 100 and the second engaging portion 2014, and the staff can remove the cover plate 100 from the receiving portion 201 by hand. Fig.12 , Fig.11 , Fig.10 , Fig. 9 , Figure 8 , which is the opposite of the process of installing the cover plate 100 .

[0094] At this point, the cover plate 100 and the body 200 can be disassembled without tools.
