Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0039] For the orientation terms involved in the embodiments of the present application, such as "upper", "lower", "side", etc., generally take Figure 1 the relative relationship of the orientation shown in the

[0040] as the reference, and the use of these orientation terms is only to more clearly describe the relationship between structures and structures, rather than to describe the absolute orientation. When the product is placed in different postures, the orientation may change. For example, "upper" and "lower" may be interchanged.

[0041] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0042] As shown Figures 2 to 10 In the embodiment of the present application, a rubber rubbing fixing device is provided, which is applied to a foldable electronic device 100. The electronic device 100 can be a mobile phone, a tablet computer, a notebook computer, an e-reader, a smart wearable device, a virtual reality device, a driving recorder, etc., and the electronic device 100 can be folded and unfolded. For example, the electronic device 100 is a foldable mobile phone.

[0043] As shown Figure 1 In the embodiment of the present application, the electronic device 100 includes a first main body 101, a second main body 102, a rotating shaft cover 103, a middle frame (not shown in the figure), a main screen (not shown in the figure), and a secondary screen 104. The electronic device 100 has a folded state and an unfolded state. The first main body 101 and the second main body 102 are rotatably connected through the rotating shaft cover 103 to switch between the folded state and the unfolded state. The middle frame is disposed inside the first main body 101 and the second main body 102, and there is a gap between the rotating shaft cover 103 and the middle frame. Both the main screen and the secondary screen 104 are mounted on the middle frame. The main screen is disposed on the first main body 101 and the second main body 102, and the secondary screen 104 is disposed on the first main body 101 or the second main body 102. The secondary screen 104 is located on the side of the middle frame away from the main screen.

[0044] The first main body 101 and the second main body 102 can rotate around the rotating shaft cover 103 towards each other to the folded state, and the first main body 101 and the second main body 102 can also rotate around the rotating shaft cover 103 away from each other to the unfolded state to meet different usage requirements of users.

[0045] Among them, the main screen can be a flexible screen, and the main screen covers the first main body 101 and the second main body 102. When the electronic device 100 is in the folded state, the main screen is also in the folded state; when the electronic device 100 is in the unfolded state, the main screen is in the unfolded state.

[0046] The folding method of the main screen can be inward folding or outward folding. In the embodiment of the present application, the inward folding method of the main screen is taken as an example for illustration. That is, when the electronic device 100 is in the folded state, the main screen is located on two opposite surfaces of the first main body 101 and the second main body 102 close to each other.

[0047] The secondary screen 104 is located on one of the first main body 101 and the second main body 102, and the secondary screen 104 faces away from the main screen. For example Figure 1 As shown, the secondary screen 104 is located on the first main body 101.

[0048] As shown Figure 2As shown, the rubber scraping and fixing device includes a base assembly 1. The base assembly 1 includes a fixing base 11 and a shielding member 12. The fixing base 11 has a bearing portion 111 for carrying the electronic device 100. The shielding member 12 is connected to one side of the fixing base 11 in the first direction. The shielding member 12 is configured to be movable in the first direction to approach or depart from the bearing portion 111. The shielding member 12 is used to shield the gap between the rotating shaft cover 103 and the middle frame. Exemplarily, the first direction is the width direction of the fixing base 11, and the shielding member 12 is connected to one side of the fixing base 11 in the width direction.

[0049] The rubber scraping and fixing device is applied to the assembly process of the electronic device 100, especially suitable for the process of assembling the secondary screen 104.

[0050] Specifically, fix the rubber scraping and fixing device to the rubber scraping equipment, place the folded electronic device 100 on the bearing portion 111 of the fixing base 11, so that the area for installing the secondary screen 104 on the electronic device 100 is exposed, which is convenient for the rubber scraping equipment to perform rubber scraping treatment on the gap between the secondary screen 104 and the middle frame after the assembly of the secondary screen 104 is completed. After the rubber scraping is completed, the electronic device 100 can be taken out from the bearing portion 111.

[0051] Among them, since the gap between the rotating shaft cover 103 and the middle frame in the folded electronic device 100 is exposed, during the rubber scraping process, adhesives such as overflowing hot melt glue may penetrate into the gap, and it is necessary to disassemble the whole machine to remove the overflowing glue, which affects the assembly efficiency of the electronic device 100 and also increases the material loss cost. The rubber scraping and fixing device provided by the embodiment of the present application can move the shielding member 12 towards the bearing portion 111 during the rubber scraping treatment by setting the shielding member 12 to shield the gap between the rotating shaft cover 103 and the middle frame, preventing adhesives such as overflowing hot melt glue from penetrating into the gap during the rubber scraping process and ensuring the normal progress of the rubber scraping work.

[0052] The rubber scraping and fixing device provided by the embodiment of the present application, by setting the base assembly 1 including the fixing base 11 and the shielding member 12, after placing the electronic device 100 on the bearing portion 111, can move the shielding member 12 towards the position where the bearing portion 111 is located to shield the gap between the rotating shaft cover 103 and the middle frame, avoiding the hot melt glue from entering the gap between the rotating shaft cover 103 and the middle frame during the rubber scraping process, effectively solving the problem that the glue overflows into the interior of the electronic device 100 during the rubber scraping process, improving the production efficiency of the electronic device 100, and avoiding increasing the material loss cost due to disassembling the whole machine; after the rubber scraping is completed, by moving the shielding member 12 in the direction away from the bearing portion 111, it is convenient to take out the electronic device 100.

[0053] In a further embodiment, as Figure 3As shown, the shielding member 12 includes a pressing head portion 121, a connecting portion 122, and a positioning portion 123. The pressing head portion 121 and the positioning portion 123 are connected to the same side of the connecting portion 122 and are spaced apart in the second direction. The pressing head portion 121 extends in the third direction and is adapted to cover the gap between the rotating shaft cover 103 and the middle frame. The positioning portion 123 is used to position the shielding member 12 on the fixing base 11.

[0054] Among them, the first direction, the second direction, and the third direction are perpendicular to each other. Exemplarily, the second direction is the thickness direction of the fixing base 11, and the third direction is the length direction of the fixing base 11.

[0055] Specifically, as Figure 3 shown, the pressing head portion 121 extends in a strip or rod shape along the third direction. When the electronic device 100 in the folded state is placed on the bearing portion 111, the rotating shaft cover 103 extends in the third direction, and the pressing head portion 121 can be parallel to the extending direction of the rotating shaft cover 103, fully covering the gap between the rotating shaft cover 103 and the middle frame, effectively preventing the adhesive from penetrating into the gap.

[0056] As Figure 3 shown, the first end in the length direction of the connecting portion 122 is connected to the pressing head portion 121, and the second end in the length direction of the connecting portion 122 is connected to the positioning portion 123. When the positioning of the shielding member 12 and the fixing base 11 is completed, the pressing head portion 121 and the positioning portion 123 are located on the same side of the connecting portion 122. For example Figure 3 shown, both the pressing head portion 121 and the positioning portion 123 are located on the left side of the connecting portion 122. The positioning portion 123 extends in the first direction, facilitating positioning on the fixing base 11. At the same time, the pressing head portion 121 shields the gap between the rotating shaft cover 103 and the middle frame on one side in the width direction of the bearing portion 111.

[0057] Among them, the positioning between the positioning portion 123 and the fixing base 11 can be achieved by means of hole-column cooperation, slide rails, sliding grooves, threaded connections, snap connections, etc. While realizing the connection between the fixing base 11 and the shielding member 12, the pressing head portion 121 is located at the position where the rotating shaft cover 103 and the middle frame are located after positioning is completed, fully blocking the gap between the rotating shaft cover 103 and the middle frame, and improving the anti-overflow glue effect.

[0058] Optionally, both the connecting portion 122 and the positioning portion 123 are multiple. For example Figure 3 shown, both the connecting portion 122 and the positioning portion 123 are two. Each connecting portion 122 is correspondingly connected to a positioning portion 123, and the two connecting portions 122 are spaced apart along the extending direction of the pressing head portion 121.

[0059] By setting both the connecting portion 122 and the positioning portion 123 to be multiple, it is beneficial to improve the positioning accuracy between the fixing base 11 and the shielding member 12, and improve the stability and reliability of the connection between the fixing base 11 and the shielding member 12.

[0060] In this embodiment, the positioning portion 123 is provided to achieve positioning of the shielding member 12 and the fixing seat 11, so that the position of the pressure head portion 121 matches the position of the shaft cover 103, effectively preventing the adhesive from penetrating into the gap between the shaft cover 103 and the middle frame.

[0061] In a further embodiment, the pressing head portion 121 includes a pressing head body 121 a and a folded edge 121 b which are connected to each other. The folded edge 121 b is folded relative to the pressing head body 121 a toward a side away from the connecting portion 122 .

[0062] The pressure head body 121a and the folded edge 121b both extend along the third direction, and the folded edge 121b and the pressure head body 121a are arranged at an angle, for example Figure 4 As shown, the folded edge 121b is perpendicularly arranged to the pressure head body 121a, so that the cross section of the pressure head 121 is roughly "L" shaped. It can be understood that the above "cross section" is a cross section obtained by cutting along a direction perpendicular to the extension direction of the pressure head 121.

[0063] Exemplarily, the width direction of the press head body 121a is parallel to the second direction, the press head body 121a is connected to the connecting portion 122, and the folded edge 121b is located on the side of the press head body 121a away from the positioning portion 123, for example, the folded edge 121b is located on the upper side of the press head body 121a. Figure 5 As shown, when the shielding member 12 and the fixing seat 11 are positioned, the pressing head body 121a can abut against the shaft cover 103, and the folded edge 121b covers the gap between the shaft cover 103 and the middle frame to fully shield the gap.

[0064] Alternatively, if Figure 4 and Figure 5 As shown, a curved surface structure is provided at the connection between the pressure head body 121a and the folded edge 121b on the side close to the shaft cover 103 to fully adapt to the rounded chamfer shape of the edge of the shaft cover 103 so that the pressure head 121 fits better with the shaft cover 103.

[0065] In a specific embodiment, Figure 6 As shown, a positioning groove 112 is formed on the edge of the fixing seat 11 , and the positioning groove 112 is configured to be suitable for being inserted by the positioning portion 123 along the first direction.

[0066] Among them, the depth of the positioning groove 112 can be the same as the thickness of the fixing seat 11, that is, the positioning groove 112 penetrates the fixing seat 11 along the thickness direction of the fixing seat 11; the depth of the positioning groove 112 can also be less than the thickness of the fixing seat 11, that is, the positioning groove 112 does not penetrate the fixing seat 11 along the thickness direction of the fixing seat 11.

[0067] Specifically, ifFigure 6 As shown, the positioning groove 112 is located in the edge area of the fixing base 11. The dimension of the positioning groove 112 in the first direction is smaller than the dimension of the fixing base 11, that is, the positioning groove 112 does not penetrate the fixing base 11 along the width direction of the fixing base 11. The positioning groove 112 has a bottom wall and side walls perpendicular to the bottom wall. The side walls are respectively connected to the bottom surface of the fixing base 11 and the side surface of the fixing base 11 in the width direction, so that the positioning groove 112 forms an opening on the bottom surface and the side surface in the width direction of the fixing base 11, facilitating the insertion of the positioning portion 123.

[0068] In this embodiment, the positioning portion 123 can enter the positioning groove 112 from the opening at the edge of the fixing base 11 along the first direction and slide along the first direction. When the front end of the positioning portion 123 abuts against the side wall of the fixing base 11 and cannot move forward further, the positioning connection between the shielding member 12 and the fixing base 11 is completed.

[0069] Optionally, the shape and size of the positioning groove 112 are adapted to the shape and size of the positioning portion 123 to limit the positioning portion 123 in the first, second, and third directions simultaneously, ensuring that the positioning portion 123 is inserted into the positioning groove 112 along the first direction to complete the positioning.

[0070] It can be understood that the shape of the positioning groove 112 being adapted to the shape of the positioning portion 123 means that the shapes of the positioning groove 112 and the positioning portion 123 are the same. For example Figure 6 as shown, both the shape of the positioning groove 112 and the shape of the positioning portion 123 are in the shape of a cuboid; the size of the positioning groove 112 being adapted to the size of the positioning portion 123 means that the size of the positioning groove 112 is equal to or slightly larger than the size of the positioning portion 123, so that the positioning groove 112 can not only accommodate the positioning portion 123, but also play a certain limiting role on the positioning portion 123 to prevent the positioning portion 123 from being deflected during the positioning process.

[0071] In a specific embodiment, the shielding member 12 further includes a magnetic portion 124. The magnetic portion 124 is disposed on the positioning portion 123, and the magnetic portion 124 is used for magnetic connection with the fixing base 11.

[0072] Specifically, the fixing base 11 has magnetism, or the fixing base 11 is provided with a magnetic member that can be magnetically attracted to the magnetic portion 124. By providing the magnetic portion 124, the positioning portion 123 is magnetically connected to the fixing base 11, facilitating the rapid and accurate positioning of the shielding member 12 and the fixing base 11 by using magnetic attraction, and being beneficial to realizing the stable connection between the shielding member 12 and the fixing base 11.

[0073] Such as Figure 3 as shown, the magnetic portion 124 is embedded in the positioning portion 123, which is beneficial to saving the space occupied by the magnetic member and making the structure of the shielding member 12 compact and reasonable.

[0074] Optionally, there are multiple magnetic parts 124, which is beneficial to improving the stability and reliability of the magnetic connection between the magnetic parts 124 and the fixing base 11. For example Figure 3 As shown, two magnetic parts 124 are installed in each positioning part 123.

[0075] Optionally, as Figure 3 shown, the shielding part 12 further includes a positioning block 125 and a connecting rod 126. The positioning block 125 is connected to the side of the connecting part 122 facing the positioning part 123. One end of the connecting rod 126 is connected to the positioning block 125, and the other end is connected to the positioning part 123. Among them, the positioning block 125 is used to directly or indirectly push tightly against the electronic device 100 to complete the positioning of the shielding part 12 and the fixing base 11.

[0076] Exemplarily, the positioning process between the shielding part 12 and the fixing base 11 includes: inserting the positioning part 123 into the positioning groove 112, and moving the shielding part 12 in the first direction to approach the electronic device 100. When the front end of the positioning part 123 abuts against the side wall of the fixing base 11, the positioning block 125 abuts against the fixing base 11 or the electronic device 100, and the magnetic part 124 and the fixing base 11 are magnetically connected, the shielding part 12 is installed in place, and at this time, the positioning and installation of the shielding part 12 on the fixing base 11 is completed.

[0077] In one embodiment, the rubber wiping and fixing device further includes a support plate 2. The support plate 2 is movably connected to the fixing base 11 to approach or move away from the bearing part 111. There is a spacing between the support plate 2 and the bearing part 111 in the thickness direction of the fixing base 11. Among them, the support plate 2 is adapted to support the secondary screen 104.

[0078] Exemplarily, the support plate 2 is located above the fixing base 11 and is spaced from the fixing base 11. The support plate 2 can move in the third direction to approach or move away from the bearing part 111. Among them, the support plate 2 and the fixing base 11 can be movably connected by means of slide rail cooperation, chute cooperation, etc.; the support plate 2 and the fixing base 11 can also be detachably connected by means of bolt connection, movable buckle connection, etc. When the support plate 2 is connected to the fixing base 11, the support plate 2 is located above the fixing base 11 and close to the bearing part 111. When the support plate 2 is separated from the fixing base 11, the support plate 2 is taken out to move away from the bearing part 111.

[0079] The pallet 2 is used before the secondary screen 104 is assembled to the middle frame. Specifically, after applying glue to the middle frame, move the pallet 2 closer to the bearing part 111 so that the pallet 2 can block the adhesive, prevent the adhesive from being touched by other components or equipment, avoid affecting the bonding between the secondary screen 104 and the middle frame, and at the same time avoid polluting the assembly environment. Then place the secondary screen 104 on the pallet 2, electrically connect the secondary screen 104 to the main board of the electronic device 100 through a board-to-board connector. When it is necessary to install the secondary screen 104 into the middle frame, take out the secondary screen 104 and move the pallet 2 away from the bearing part 111, and then the assembly of the secondary screen 104 and the middle frame can be carried out.

[0080] Exemplarily, as Figure 7 shown, one end of the pallet 2 in the length direction is open, so that the pallet 2 is in a "U" shape, which is convenient for avoiding other components or equipment. The pallet 2 is provided with a fixing groove 23 for placing the secondary screen 104.

[0081] In a further embodiment, as Figure 8 shown, the fixing seat 11 further includes a sliding groove part 113, and the sliding groove part 113 is arranged on both sides of the bearing part 111. As Figure 7 shown, the pallet 2 includes a pallet body 21 and mounting parts 22 arranged on both sides of the pallet body 21. The mounting parts 22 are configured to be suitable for inserting into the sliding groove part 113 and moving along the extension direction of the sliding groove part 113.

[0082] As Figure 8 shown, the sliding groove part 113 is located on both sides of the fixing seat 11 along the first direction, and the sliding groove part 113 extends along the third direction. The mounting part 22 is in a plate shape or a sheet shape. The mounting part 22 is connected to one side surface (such as the lower surface) of the pallet body 21 in the thickness direction. The mounting part 22 is perpendicular to the pallet body 21 and extends along the length direction of the pallet body 21. The sliding groove part 113 can accommodate the mounting part 22, so that the mounting part 22 slides along the extension direction of the sliding groove part 113, and thus approaches or moves away from the bearing part 111.

[0083] In a further embodiment, the glue wiping and fixing device further includes a pressing component 3. The pressing component 3 is detachably connected to the fixing seat 11 and is arranged opposite to the bearing part 111.

[0084] As Figure 10 shown, the pressing component 3 is located above the base component 1. When the pressing component 3 is connected to the fixing seat 11, the pressing component 3 can apply pressure to the secondary screen 104 after the secondary screen 104 and the middle frame are assembled, and maintain the shape of the secondary screen 104 until the adhesive cures. At the same time, the pressing component 3 can make the adhesive between the secondary screen 104 and the middle frame overflow by pressing the secondary screen 104, which is convenient for the glue wiping device to wipe off the excess glue.

[0085] Exemplarily, the lamination assembly 3 and the fixing base 11 are detachably connected by means of movable buckles, threaded connections, etc., facilitating the installation and disassembly of the two.

[0086] In a specific embodiment, as Figure 11 shown, a first clamping member 114 protrudes from the upper surface of the fixing base 11, and the lamination assembly 3 has a second clamping member 36. The first clamping member 114 and the second clamping member 36 are cooperatively connected to achieve the detachable connection between the lamination assembly 3 and the fixing base 11. Further, the first clamping member 114 has a clamping protrusion 114a extending in the third direction, and the second clamping member 36 has a clamping step 36a. The clamping protrusion 114a can abut against the clamping step 36a in the second direction to complete the cooperative connection between the first clamping member 114 and the second clamping member 36, and limit the lamination assembly 3 in the second direction.

[0087] In a further embodiment, as Figure 9 shown, the lamination assembly 3 includes an installation body 31, a pressing plate 32, an elastic threaded member 33, and a fixing threaded member 34. The installation body 31 and the pressing plate 32 are stacked and connected by the fixing threaded member 34. The pressing plate 32 is located on the side of the installation body 31 close to the fixing base 11. The elastic threaded member 33 is connected between the installation body 31 and the pressing plate 32, and the elastic threaded member 33 is used to adjust the pressing force between the pressing plate 32 and the secondary screen 104.

[0088] As Figure 9 shown, the installation body 31 and the pressing plate 32 are stacked in the second direction. The pressing plate 32 is located on the side of the installation body 31 close to the fixing base 11. The pressing plate 32 is used to contact the secondary screen 104 and generate a pressure on the secondary screen 104.

[0089] Specifically, after the secondary screen 104 is assembled to the middle frame, the pressing plate 32 contacts the secondary screen 104 and generates a pressure in the second direction on the secondary screen 104, playing a pre-pressing role on the secondary screen 104 and maintaining the shape of the secondary screen 104 until the adhesive cures.

[0090] The fixing threaded member 34 realizes the pre-connection between the installation body 31 and the pressing plate 32, maintaining the relative positions of the installation body 31 and the pressing plate 32 fixed. The elastic threaded member 33 is provided with elastic members such as springs. The installation body 31 is provided with threaded holes. One end of the elastic threaded member 33 is cooperatively connected with the threaded holes, and the other end abuts against the surface of the pressing plate 32 close to the installation body 31. By adjusting the number of rotations of the elastic threaded member 33 screwed into the threaded holes, the compression amount of the elastic member is controlled, and further the pressing force of the pressing plate 32 on the secondary screen 104 is adjusted, preventing excessive glue overflow of the secondary screen 104 due to excessive pressure, and at the same time avoiding insufficient pressure affecting the connection strength between the secondary screen 104 and the middle frame.

[0091] As Figure 9As shown, there are multiple fixed threaded parts 34 and elastic threaded parts 33, which can improve the connection reliability between the mounting body 31 and the pressing plate 32.

[0092] Specifically, second clamping parts 36 are respectively arranged at both ends of the mounting body 31 in the length direction, and first clamping parts 114 are respectively arranged at both ends of the fixed seat 11 in the length direction. Both ends of the mounting body 31 in the length direction are detachably connected to both ends of the fixed seat 11 in the length direction. Further, the pressing assembly 3 further includes two connecting frames 35, which are respectively arranged at both ends of the mounting body 31 in the length direction. Each connecting frame 35 corresponds to connect a second clamping part 36. The connecting frame 35 is in a shape suitable for being grasped by a person, such as an arc-shaped handle or a rectangular handle shape, which is convenient for a person to hold and operate. For example Figure 9 As shown, the connecting frame 35 is in the shape of a rectangular handle.

[0093] One of the fixed seat 11 and the second clamping part 36 is convexly provided with a positioning pin 115, and the other is correspondingly provided with a positioning hole. By inserting the positioning pin 115 into the positioning hole, precise positioning of the mounting body 31 and the fixed seat 11 is achieved to ensure the correct position of the pressing plate 32 and ensure uniform force on the secondary screen 104 during the process of the pressing plate 32 being buckled on the surface of the secondary screen 104. As Figure 2 As shown, the fixed seat 11 is convexly provided with a positioning pin 115.

[0094] The fixed seat 11 further includes a limiting part 116, and the limiting part 116 is located at the edge of the bearing part 111 and protrudes outward in the thickness direction of the fixed seat 11.

[0095] As Figure 2 As shown, the limiting part 116 protrudes outward on the upper surface of the fixed seat 11. The limiting part 116 is used to limit the electronic device 100 placed on the bearing part 111 to prevent the position of the electronic device 100 from shifting. Optionally, there are multiple limiting parts 116, and the multiple limiting parts 116 are distributed at intervals around the edge of the bearing part 111.

[0096] In a specific embodiment, the usage process of the rubber wiping and fixing device provided by the embodiment of the present application includes:

[0097] Place the folded electronic device 100 without the secondary screen 104 installed on the bearing part 111, so that the side of the electronic device 100 where the secondary screen 104 is to be installed is exposed;

[0099] Insert the installation part 22 of the tray 2 into the sliding groove part 113, and push the tray 2 along the third direction to move the tray 2 above the bearing part 111;

[0100] Place the secondary screen 104 on the fixing groove 23 of the pallet 2, and insert the board-to-board connector of the secondary screen 104 into the female connector on the main board of the electronic device 100 to achieve electrical connection between the secondary screen 104 and the main board;

[0101] Insert the positioning portion 123 into the positioning groove 112, and move the shielding member 12 in the first direction to approach the electronic device 100. When the front end of the positioning portion 123 abuts against the side wall of the fixed seat 11, the positioning block 125 abuts against the fixed seat 11 or the electronic device 100, and the magnetic portion 124 is magnetically connected to the fixed seat 11, the shielding member 12 is installed in place;

[0102] Assemble the secondary screen 104 to the middle frame;

[0103] Insert the positioning pin 115 into the positioning hole, connect the second engaging member 36 of the pressing assembly 3 and the first engaging member 114 on the fixed seat 11, so that the pressing plate 32 covers the secondary screen 104, and screw the adjusting elastic threaded member 33 to press the secondary screen 104 with an appropriate pressure;

[0104] The rubber wiping device performs rubber wiping treatment on the electronic device 100.
