The protection piece is arranged on one side of the shell close to the rotating shaft assembly, and the protection piece abuts against the appearance surface of the rotating shaft assembly, so that a water inlet path and a dust inlet path between the shell and the rotating shaft assembly are blocked, and therefore external foreign matters such as water, dust and the like can be effectively prevented from entering the electronic equipment, and the dustproof and waterproof performance of the electronic equipment is improved.

The foldable electronic equipment comprises a first shell, a second shell and a rotating shaft assembly, wherein the rotating shaft assembly is connected with the first shell and the second shell, and the first shell and the second shell can be relatively unfolded or relatively folded through the movement of the rotating shaft assembly so as to enable the electronic equipment to be in an open state or a closed state;

In the application, the electronic equipment is folded through the motion fit of the two shells and the middle rotating shaft group, and the motion fit causes a motion gap between the structural members of the whole machine. This application has plugged up the movement clearance between first shell and the outward appearance face through set up the protector in one side that first casing is close to pivot subassembly, prevents that foreign matters such as water and dust from getting into the complete machine inner chamber from the movement clearance to improve electronic equipment's dustproof, waterproof performance.

In addition, the first shell and the second shell can rotate towards each other to a folded state so as to change the electronic equipment from an opened state to a closed state; or back to the unfolded state, so that the electronic equipment is changed from the closed state to the open state. In the process of the electronic equipment changing the form, the first shell can slide close to the appearance surface of the rotating shaft assembly. The protection piece can move along with the first shell, so that the protection piece always supports against the appearance surface of the rotating shaft assembly, and the dustproof and waterproof performance of the electronic equipment in the moving process is ensured.

In a possible implementation manner, the protection piece can support the appearance surface of the rotating shaft assembly and has a powerful action with the appearance surface. In other possible implementation manners, the protection piece can also contact the appearance surface of the rotating shaft assembly, but no force is applied between the protection piece and the appearance surface, so that the friction resistance when the first shell and the appearance surface move relatively is reduced, the moving process is smoother, no blocking feeling exists, and the use experience of a user is improved.

In one possible implementation manner, the protective element is made of elastic deformation material and is in interference fit with the appearance surface of the rotating shaft assembly. In this implementation, when the protection piece is filled in the movement gap, the protection piece is elastically deformed by being squeezed, and the action of force is generated between the protection piece and the appearance surface of the rotating shaft assembly, so that no gap is formed between the appearance surface and the protection piece, and therefore foreign matters such as water and dust are prevented from entering the inner cavity of the whole machine through the movement gap.

In one possible embodiment, the protective element is provided with an interference, which is 0.1 mm.

In some implementations, the first extension and the second extension may also be used to cooperate with other structural members to further improve the dust-proof and water-proof performance of the electronic device.

In one possible implementation, the protection part is made of soft rubber material. In this implementation, the soft rubber material is soft, yielding, can make and produce the friction that has the adhesion nature between protection piece and the outward appearance face, even also can guarantee in the motion process that there is not clearance between outward appearance face and the protection piece to promote the protective properties of protection piece in the motion process.

Therefore, the convex ribs are only in interference fit with the appearance surfaces of the rotating shaft assembly at the thin upper ends, the contact area is small, so that small friction resistance is generated, and the resistance to relative movement between the first shell and the appearance surfaces of the rotating shaft assembly is small. In other possible implementation manners, the convex rib can also contact the appearance surface of the rotating shaft assembly, but deformation does not occur, namely no force action exists between the convex rib and the appearance surface, so that the friction resistance when the first shell and the appearance surface move relatively is reduced, the moving process is smoother, no blocking feeling exists, and the use experience of a user is improved.

Referring to fig. 1A and fig. 1B together, fig. 1A is a schematic structural diagram of an electronic device 100 in an open state according to an embodiment of the present disclosure, and fig. 1B is a schematic structural diagram of the electronic device 100 in a closed state shown in fig. 1A.

In some embodiments, the electronic device 100 includes a housing device 1 and a screen 2, the screen 2 is mounted on the housing device 1, and the housing device 1 and the screen 2 together enclose an internal cavity of the electronic device 100. As shown in fig. 1A, the housing device 1 can be unfolded to an open state; as shown in fig. 1B, the housing device 1 may also be folded to a closed state. The housing device 1 may also be unfolded or folded to an intermediate state, and the intermediate state may be any state between the open state and the closed state. The screen 2 moves along with the housing device 1, and the housing device 1 can drive the screen 2 to unfold or fold, so that the electronic device 100 can unfold to an open state or fold to a closed state.

In the present embodiment, when the electronic apparatus 100 is in the open state, the screen 2 is flattened. At this time, the screen 2 can be displayed in a full screen, so that the electronic device 100 has a larger display area to improve the viewing experience and the operating experience of the user. When the electronic device 100 is in the closed state, the electronic device 100 has a small planar size, and is convenient for a user to carry and store.

It is understood that, in the embodiment of the present application, the electronic device 100 is illustrated as a two-fold structure, that is, the electronic device 100 includes two flat plate portions and a bending portion connected between the two flat plate portions; the two flat plate portions may rotate in opposite directions to be stacked (corresponding to the closed state) to make the electronic device 100 present a two-layer configuration; the two flat plate portions may also be turned back to lie flat (corresponding to the previously opened state). In other embodiments, the electronic device 100 may also have a structure with more than three folds, that is, the electronic device 100 includes more than three flat plate portions, two adjacent flat plate portions are connected by a bent portion, and two adjacent flat plates may rotate relative to each other to be stacked or rotate back to be flattened. When the electronic device 100 has the structure of three-fold, the structure of the electronic device 100 may be adaptively designed according to the description of the two-fold structure of this embodiment, which is not described herein again.

Referring to fig. 1A, fig. 1B and fig. 2 in combination, fig. 2 is a schematic partial exploded view of the electronic device 100 shown in fig. 1A.

In some embodiments, the housing device 1 may include a first housing 11, a second housing 12, and a rotary shaft assembly 13.

Wherein the rotating shaft assembly 13 may be connected between the first housing 11 and the second housing 12. The rotary shaft assembly 13 is movable to enable the first housing 11 and the second housing 12 to be relatively unfolded to an open state and relatively folded to a closed state.

The screen 2 is located above the first housing 11, the rotating shaft assembly 13 and the second housing 12, and is fixedly connected to the first housing 11, the rotating shaft assembly 13 and the second housing 12. In the embodiment of the present application, the same orientation as the light exit direction of the screen 2 is defined as "up", and the opposite orientation to the light exit direction of the screen 2 is defined as "down". The screen 2 can move following the first housing 11, the rotary shaft assembly 13 and the second housing 12, thereby realizing unfolding and folding.

Illustratively, the rotating shaft assembly 13 includes a central shaft 131, a first support plate 132, a second support plate 133, and a back cover 134. The first and second support plates 132 and 133 are respectively located at both sides of the central axis 131 to support the screen 2.

Illustratively, the back cover 134 is positioned below the central shaft 131 and fixedly connected to the central shaft 131. Specifically, the back cover 134 is substantially a cover structure with a concave middle portion and two raised sides. The upper surface of the back cover 134 is recessed to form a receiving space for receiving the center shaft 131. The back cover 134 is located outside the center shaft 131 and can cover the center shaft 131, so as to improve the appearance consistency and the aesthetic property of the electronic device 100 and facilitate the user to hold the electronic device 100. In the present application, the lower surface of the back cover 134 forms the external surface of the back cover 134, and the external surface of the back cover 134 constitutes the external surface 130 of the spindle assembly 13.

When the electronic device 100 is in the open state, the first housing 11 and the second housing 12 are relatively flat and cover the back cover 134 together, that is, the first housing 11 and the second housing 12 cover the rotating shaft assembly 13 together. At this time, the back cover 134 is hidden between the middle shaft 131 and the first and second housings 11 and 12. When the electronic apparatus 100 is in the closed state, the first housing 11 and the second housing 12 are folded relatively, and the back cover 134 is exposed relative to the first housing 11 and the second housing 12. At this time, the external surface 130 of the rotary shaft assembly 13 is exposed to the first housing 11 and the second housing 12.

Referring to fig. 2 and fig. 3, fig. 3 is a partial schematic view of a cross-sectional structure of the electronic device 100 shown in fig. 1A taken along a-a. In some embodiments, the first housing 11 may further include a protection member 111 fixedly installed on a side of the first housing 11 close to the rotating shaft assembly 13, and the protection member 111 abuts against the appearance surface 130 of the rotating shaft assembly 13.

In the present application, the electronic device 100 is folded by the two housings (11, 12) cooperating with the movement of the central spindle assembly 13, and this cooperation results in a movement gap 140 between the structural members of the whole device. In the embodiment of the present application, the protection element 111 is disposed on one side of the first housing 11 close to the rotating shaft assembly 13, so as to block the movement gap 140 between the first housing 11 and the appearance surface 130, and prevent foreign matters such as water and dust from entering the inner cavity of the electronic device 100 from the movement gap 140, thereby improving the dustproof and waterproof performance of the electronic device 100.

For example, the protection member 111 may support the appearance surface 130 of the rotating shaft assembly 13 and strongly act with the appearance surface 130. In other possible embodiments, the protection element 111 may also contact the appearance surface 130 of the rotating shaft assembly 13, but no force is applied between the appearance surface 130 and the protection element to reduce the frictional resistance when the first housing 11 and the appearance surface 130 move relatively, so that the moving process is smoother and has no stagnation, and the use experience of the user is improved.

For example, referring to fig. 4, fig. 4 is a schematic structural diagram of the first housing 11 and the protection member 111 shown in fig. 2. The first housing 11 may be provided with a recess 110 having an upward opening, and the shielding member 111 may be fixedly mounted on a groove wall of the recess 110. The walls of the groove 110 may include a first side 1101, a second side 1102, and a third side 1103 connected in series. The second side 1102 is close to the external surface 130 of the rotating shaft assembly 13 relative to the first side 1101 and the third side 1103. The shielding part 111 may include a shielding part 111b connected in sequence, and a first extension part 111a and a second extension part 111c connected to both ends of the shielding part 111b, respectively.

Referring to fig. 3 and 4, the protection portion 111b is located near the second side edge 1102 and abuts against the external surface 130 of the rotating shaft assembly 13, so as to block the movement gap 140 between the first housing 11 and the external surface 130 of the rotating shaft assembly 13, thereby preventing foreign objects such as water and dust from entering the inner cavity of the whole machine through the movement gap 140. The first extension 111a and the second extension 111c are respectively located near the first side 1101 and the third side 1103 for increasing the connection firmness between the protection member 111 and the first housing 11. In some embodiments, the first extension portion 111a and the second extension portion 111c may also be used to cooperate with other structural members, so as to further improve the dust-proof and water-proof performance of the electronic device 100.

For example, the shielding element 111 may be disposed at an edge close to a side edge of a groove wall of the groove 110, so as to effectively block external impurities from entering the cavity of the whole machine, thereby avoiding damage to components located in the cavity of the whole machine, while minimizing occupation of the cavity space of the whole machine, and reserving sufficient space for arrangement of the components.

In some other embodiments, the protection part 111 may include only the protection part 111b, so as to reduce the occupied space of the whole internal cavity, and further reduce the volume of the electronic device 100, which is beneficial to meet the requirement of miniaturization.

For example, the protection part 111b of the protection part 111 may be a continuous strip structure, that is, the protection part 111b extends from one end of the appearance surface 130 of the rotating shaft assembly 13 to the other end and continuously contacts the appearance surface 130, so as to ensure that no gap exists between the protection part 111b and the appearance surface 130 of the rotating shaft assembly 13, and improve the protection performance of the electronic device 100.

It is understood that the first extension portion 111a and the second extension portion 111c may have the same structure as the protection portion 111b or different structures, and the embodiment of the present application is not limited thereto.

For example, the first housing 11 can slide close to the appearance surface 130 of the rotating shaft assembly 13, and the movement gap 140 between the first housing 11 and the appearance surface 130 of the rotating shaft assembly 13 is uniform, so that the protective part 111b has a uniform effect on the appearance surface 130, and the relative movement between the first housing 11 and the cover plate 14 is prevented from being affected by the clamping stagnation.

In some embodiments, the first housing 11 may be provided with a mounting groove 112, and the protection member 111 may be partially fitted in the mounting groove 112 to be fixed on the first housing 11, so as to improve the connection strength. For example, glue may be applied to the mounting slot 112, so that the protection member 111 and the wall of the mounting slot 112 are adhered together by the glue, and the protection member 111 is prevented from falling off. In other embodiments, the first housing 11 may not have the mounting slot 112, and the protection member 111 may be directly fixed on the slot wall of the recess 110 by glue or double-sided tape.

Referring to fig. 2 again, in the embodiment of the present application, the second housing 12 may have a different structure from the first housing 11. The second housing 12 includes a guard 121. The shielding member 121 of the second housing 12 may have the same structure as the shielding member 111 of the first housing 11, and thus, the description thereof is omitted. In other embodiments, the structure of the shielding member 121 of the second housing 12 may also be different from that of the shielding member 111 of the first housing 11, which is not limited in this embodiment.

For example, the second housing 12 may not include the protection member 121, or may adopt other waterproof and/or dustproof methods, which is not limited in the embodiment of the present application.

It is understood that the first housing 11 and the second housing 12 are housing members for mounting and fixing other components of the electronic device 100, and have various structures, and the embodiment of the present application is only to briefly describe part of the structures of the first housing 11 and the second housing 12, and is also schematically illustrated in the drawings, and the embodiment of the present application is not to strictly limit the specific structures of the first housing 11 and the second housing 12.

Referring to fig. 5 and 6, fig. 5 is a schematic diagram of a cross-sectional structure of the electronic device 100 shown in fig. 1A taken along B-B in an open state and a closed state, where a structure shown by a solid line is an internal structure of the electronic device 100 in the open state shown in fig. 1A, a structure shown by a dotted line is an internal structure of the electronic device 100 in the closed state shown in fig. 1B, and fig. 6 is an enlarged schematic diagram of the cross-sectional structure shown in C of fig. 5.

For example, when the electronic device 100 is in the open state shown in fig. 1A and the closed state shown in fig. 1B, the protection member 111 abuts against the appearance surface 130 of the rotating shaft assembly 13, so as to ensure the dust-proof and water-proof performance of the electronic device 100.

In the present embodiment, the first housing 11 and the second housing 12 can rotate toward each other to a folded state (the rotation direction is shown by an arrow in fig. 5) to change the electronic device 100 from the opened state to the closed state; or back to the open state (the direction of rotation is opposite to that shown by the arrow in fig. 5) to change the electronic device 100 from the closed state to the open state. During the transformation of the electronic device 100, the first housing 11 can slide close to the appearance surface 130 of the rotating shaft assembly 13. The protection member 111 can move along with the first housing 11 so as to always abut against the appearance surface 130 of the rotating shaft assembly 13, thereby ensuring the dustproof and waterproof performance of the electronic device 100 during movement.

The present application provides an example structure of the shielding member 111, as shown in fig. 6, in the first embodiment, the cross section of the shielding member 111 may be approximately square, which is favorable for blocking larger impurities. The protective element 111 may be made of a plastically deformable material, so that the protective element 111 may be interference-fitted to the appearance surface 130 of the rotary shaft assembly 13, and the interference amount L1 is provided. That is, the protector 111 is interference-fitted with the external appearance surface 130 of the spindle assembly 13. In the present embodiment, when the protection member 111 is filled in the movement gap 140, it is elastically deformed by being pressed, and a force is generated between the protection member and the appearance surface 130 of the rotation shaft assembly 13, so as to ensure no gap between the appearance surface 130 and the protection member 111, thereby preventing foreign matters such as water and dust from entering the internal cavity of the whole machine through the movement gap 140.

In practical applications, due to design and assembly problems, when the appearance surface 130 of the first housing 11 and the rotating shaft assembly 13 moves relatively, the movement gap 140 between the two may change. When the movement gap 140 becomes larger, the shielding member 111 can still abut against the appearance surface 130 of the rotating shaft assembly 13 due to the reserved interference L1, so as to block the water inflow and dust inflow path. When the movement gap 140 is small, the protector 111 can be deformed in conformity with the shape of the exterior surface 130, and therefore, the relative movement between the first housing 11 and the exterior surface 130 is not hindered while preventing dust and water. Therefore, the reserved interference L1 enables the protection member 111 to always abut against the appearance surface 130 of the rotating shaft assembly 13 during the movement process, and improves the dust-proof and water-proof performance of the electronic device 100 during the movement process.

For example, the interference L1 may be 0.1 mm. Understandably, the magnitude of the interference L1 affects not only the shielding performance of the shielding member 111, but also the relative movement between the shielding member 111 and the appearance surface 130. Specifically, when the first housing 11 and the exterior surface 130 move relative to each other, sliding friction is generated at a portion where the protector 111 contacts the exterior surface 130, and the sliding friction force increases as the elastic force generated by elastic deformation increases. Therefore, the large interference L1 can improve the dust-proof and water-proof performance of the protection member 111, but the large interference L1 can cause the protection member 111 to generate a large elastic force, thereby increasing the resistance in the movement process; the smaller interference L1 results in less elastic force generated by the protection member 111, which makes the exercise process smooth, but reduces the protection performance. In other embodiments, the interference L1 may be adjusted according to actual situations, which is not limited in the embodiments of the present application.

In other embodiments, the protection element 111 may contact the appearance surface 130 without deformation, that is, there is no force between the protection element 111 and the appearance surface 130, so as to reduce the frictional resistance when the first housing 11 and the appearance surface 130 move relatively, so that the movement process is smoother and without retardation, thereby improving the use experience of the user.

For example, the protection member 111 may be made of soft rubber material such as rubber, silicone rubber, TPU (Thermoplastic polyurethane elastomer rubber), soft PVC (Polyvinyl chloride), and the like. The soft rubber material is soft and easy to deform, so that adhesive friction can be generated between the protection piece 111 and the appearance surface 130, and no gap can be ensured between the appearance surface 130 and the protection piece 111 even in the movement process, so that the protection performance of the protection piece 111 in the movement process is improved.

Illustratively, the protective element 111 may include 10% by mass of POM (Polyoxymethylene), so that the protective element 111 has self-lubricity, thereby reducing frictional resistance when the protective element 111 moves relative to the appearance surface 130 of the rotating shaft assembly 13, and making the movement process smoother and without stagnation, thereby improving the user experience. In other embodiments, the protection member 111 may also include a lubricating layer having lubricating properties, and the lubricating layer contacts the appearance surface 130 of the shaft assembly 13 to reduce the friction coefficient between the protection member 111 and the appearance surface 130. Specifically, the friction coefficient may be reduced by chemical surface modification methods such as halogenation, or a lubricating layer may be formed on the surface of the protection member 111 by spraying, which is not limited in the embodiment of the present application.

Another exemplary structure of the shielding element 111 is provided herein, and referring to fig. 2 and 7 together, fig. 7 is a schematic view of the cross-sectional structure shown in fig. 6 in other embodiments. The second embodiment may include most of the features of the first embodiment, and the second embodiment will be briefly described below, and most of the same contents of the second embodiment as the first embodiment will not be described again.

In a second embodiment, the guard 111 may be a rib structure, and may include a rib 112 and a base 113, for example. The rib 112 is fixed to the first housing 11 by a base 113. The lower end of the rib 112 is fixedly connected to the base 113, the upper end abuts against the outer surface 130 of the rotating shaft assembly 13, and the cross-sectional area of the upper end is smaller than that of the lower end, i.e. the upper end of the rib 112 is thinner than the lower end. Therefore, only the thin upper end of the rib 112 is in interference fit with the external surface 130 of the rotating shaft assembly 13, the contact area is small, so that small frictional resistance is generated, and the resistance to the relative movement between the first housing 11 and the external surface 130 of the rotating shaft assembly 13 is small. In the present embodiment, the area of the rib 112 in the plane parallel to the screen 2 is the cross-sectional area. The convex rib 112 extends from one end of the appearance surface 130 of the rotating shaft assembly 13 to the other end, and can continuously contact the appearance surface 130 of the rotating shaft assembly 13, so that the movement gap 140 is completely sealed, and the dustproof and waterproof performance of the electronic device 100 is improved. For example, the rib 112 may contact the appearance surface 130 of the rotating shaft assembly 13, but no deformation occurs, that is, no force acts between the rib 112 and the appearance surface 130, so as to reduce the friction resistance when the first housing 11 and the appearance surface 130 move relatively, so that the moving process is smoother and has no stagnation, thereby improving the use experience of the user.

For example, the rib 112 may have a symmetrical structure to make the elastic force generated when the rib 112 is compressed uniform. The rib 112 may also be an asymmetric structure, for example, the first interference L2 on the side of the rib 112 close to the center line of the appearance surface 130 of the rotating shaft assembly 13 is the largest, and has a larger elastic force, so that the water and dust inlet path can be blocked more tightly; the second interference L3 on the side of the convex rib 112 away from the center line of the appearance surface 130 of the rotating shaft assembly 13 is smaller, so that the generated elastic force is smaller, and the frictional resistance in the movement process is reduced, so that the movement process is smoother without stagnation.

Illustratively, the ribs 112 and the base 113 may be integrally formed structures to improve structural integrity. In other embodiments, the rib 112 and the base 113 may be assembled together, for example, the lower end of the rib 112 may be adhered to the base 113 by glue. In this case, the rib 112 and the base 113 may be made of different materials. For example, the ribs 112 may be made of a soft rubber material with self-lubricating properties to reduce frictional resistance with the appearance surface 130 of the rotating shaft assembly 13, so that the movement process of the electronic device 100 for opening and closing is smoother; and the base 113 may be made of common rubber to reduce cost. In addition, the protective performance of the bead 112 may be reduced due to long-term press friction and material aging. In this embodiment, the dust-proof and waterproof performance of the electronic device 100 can be ensured by replacing the rib 112 periodically.

Referring to fig. 8, yet another exemplary structure of a guard 111 is provided, where fig. 8 is a schematic view of the cross-sectional structure of fig. 6 in still another embodiment. The third embodiment may include most of the features of the second embodiment, and the third embodiment will be briefly described below, and most of the same contents of the third embodiment and the second embodiment will not be repeated.

In a third embodiment, the guard 111 may include a plurality of ribs fixed to the same base 116. For example, the protection member 111 may include two ribs (117, 118) to achieve double sealing, so as to reduce the space occupied by the inner cavity of the first housing 11 and reserve sufficient space for the arrangement of the elements while improving the protection performance. In other embodiments, the protection member 111 may also include more than three ribs, for example, three ribs, five ribs, and the like, which is not limited in the embodiments of the present application. That is, in the present embodiment, the protection member 111 may include a plurality of ribs fixed to the same base. It is understood that the plurality of ribs may have the same shape, or at least one rib may have a shape different from the other ribs.

Referring to fig. 1A and 9 together, fig. 9 is a schematic view of a cross-sectional structure shown in fig. 6 in still other embodiments. The fourth embodiment may include most of the features of the first embodiment, and the following briefly describes the fourth embodiment, and most of the same contents of the fourth embodiment as those of the first embodiment will not be described again.

In the fourth embodiment, the shielding member 111 may be plural, for example, two, three, six, or the like. The plurality of guard pieces 111 are arranged at intervals. It is to be understood that the shapes of the plurality of protection parts 111 may be the same, or at least one protection part 111 may have a shape different from the shapes of the other protection parts 111, which is not limited in the embodiments of the present application.

Illustratively, the plurality of guard members 111 may include a first guard member 114 and a second guard member 115. The second protection element 115 is located on a side of the first protection element 114 away from the center line of the appearance surface 130 of the rotating shaft assembly 13, and can prevent impurities such as water, dust and the like which are not blocked by the first protection element 114 from entering the internal cavity of the whole electronic device, so as to improve the dustproof and waterproof performance of the electronic device 100. Specifically, when the first protection member 114 has a reduced protection performance due to material aging or long-term squeezing and rubbing, the second protection member 115 replaces or compensates for the protection performance of the first protection member 114, thereby ensuring the dust-proof and water-proof performance of the electronic device 100 during long-term use.

For example, the shapes of the first shielding member 114 and the second shielding member 115 may be different, for example, the cross section of the first shielding member 114 may be approximately square, which is favorable for blocking larger impurities. The second shielding element 115 may have a rib structure, which is mainly used to block impurities such as water, dust, etc. that are not blocked by the first shielding element 114, so as to improve the shielding performance of the shielding element 111. In other embodiments, the shapes of the first protection part 114 and the second protection part 115 may be the same, so as to reduce the production cost of the protection part 111 and improve the production efficiency.

An example structure of a guard 111 is provided, and referring to fig. 4 and 10 together, fig. 10 is a schematic view of the cross-sectional structure shown in fig. 6 in further embodiments. The fifth embodiment may include most of the features of the first embodiment, and the fifth embodiment will be briefly described below, and most of the same contents of the fifth embodiment as those of the first embodiment will not be described again.

In a fifth embodiment, the protection member 111 may be formed by curing glue. In the present embodiment, the elastic modulus of the guard 111 may be in a range of 1Mpa to 10 Mpa. In the present embodiment, the elastic modulus of the glue after curing is low, so that the protection member 111 is easily bent and stretched, and can be rubbed with adhesion, thereby improving the protection performance against impurities such as water and dust. In addition, the manufacturing cost of the protective adhesive tape is also saved.

In the embodiment of the present application, the flow range of the glue may be limited by the mounting groove 112, so that the interference L1 can be adjusted by controlling the height of the protection member 111 formed after the glue is cured, and the like, thereby obtaining a desired protection performance. Illustratively, the height H of the guard 111 formed after the glue is cured may be 0.15 mm. In the present application, the height of the portion of the shielding member 111 exposed above the first housing 11 is the height H of the shielding member 111.
