DETAILED DESCRIPTION

[0047] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0048] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0049] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0050] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0051] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0052] In the following description, the first direction, the second direction and the third direction are three directions intersecting each other. For example, the first direction may represent the width direction of the terminal protective shell, the second direction may represent the length direction of the terminal protective shell, and the third direction may represent the thickness direction of the terminal protective shell.

[0053] like Figures 1 to 4 As shown, according to some specific embodiments of the utility model, a terminal protective shell is provided, including: a first shell 1, a second shell 2 and a communication module 3. The first shell 1 is provided with a terminal accommodating groove 101, and a button 201 is provided on the second shell 2 at a position opposite to the terminal accommodating groove 101, and the button 201 and the terminal accommodating groove 101 are arranged in the same direction in the thickness direction of the terminal protective shell. The communication module 3 is installed in the first shell 1 or the second shell 2, and the communication module 3 is used to transmit the electrical signal of the button 201. The first shell 1 can be slidably connected relative to the second shell 2 so that the button 201 is in a position such as Figure 1 The occlusion state shown or in the Figure 2 Shown in exposed state.

[0054] like Figure 1 As shown, after the terminal 5 is accommodated in the terminal accommodation slot 101, the terminal protection shell can firstly play the role of protecting the terminal 5. A button 201 is arranged on the second housing 2 at a position opposite to the terminal accommodation slot 101, which means that in the case of Figure 1 When the button 201 is in the blocked state, in the third direction, the button 201 is located below the terminal receiving groove 101 , and thus can also be located below the terminal 5 .

[0055] like Figure 2 As shown, the button 201 and the terminal receiving slot 101 are arranged in the same direction in the thickness direction of the terminal protective shell, that is, as shown in FIG. Figure 2 In the third direction shown, the button 201 and the terminal receiving slot 101 are both arranged in the positive direction indicated by the arrow in the third direction. Figure 2 When the button 201 is exposed, the screen of the terminal 5 and the button 201 are both facing the positive direction indicated by the arrow in the third direction.

[0056] like Figure 3As shown, the communication module 3 is installed in the first shell 1 or the second shell 2, and the specific installation position can be selected according to the spatial layout of the first shell 1 or the second shell 2. The communication module 3 is used to transmit the electrical signal of the key 201. When the user operates the key 201, the electrical signal can be transmitted to the terminal 5 through the communication module 3, so as to realize different functions of the game on the terminal 5, such as the character's squatting, jumping, shooting and other functions. The communication module 3 can adopt a wired communication method, or a wireless communication method such as Bluetooth, wifi, etc.

[0057] like Figure 1 and Figure 2 As shown, the first housing 1 can be slidably connected relative to the second housing 2 so that the button 201 is in a position as shown in FIG. Figure 1 The occlusion state shown or in the Figure 2 The exposed state shown. In the shielded state, the button 201 is hidden, so that the terminal 5 can be stored in a school bag, pocket, etc. together with the terminal protective shell. In the exposed state, the user can operate the button 201 to realize the game function. In a specific embodiment of the utility model, the user operates the physical button 201 of the terminal protective shell to control various functions of the terminal 5 through the communication module. The terminal 5 no longer needs to display virtual buttons, which reduces the screen area occupied. Under the same screen area conditions, the terminal 5 can display more content, so that the user's field of view will not be affected by the virtual buttons.

[0058] In some specific embodiments, the button 201 is used to control the game content of the terminal 5 in the terminal receiving slot 101, such as controlling the jumping, squatting, shooting and other actions of the game character. In some other specific embodiments, the button 201 is used to control the image processing content of the terminal 5, such as adjusting the color temperature, contrast, exposure and the like.

[0059] like Figure 5 As shown, according to some specific embodiments of the present invention, a heat exchange plate 102 is disposed in the terminal receiving tank 101 .

[0060] More specifically, according to some specific embodiments of the present invention, a heat exchange plate receiving slot 105 is provided in the terminal receiving slot 101, and after the heat exchange plate 102 is placed in the heat exchange plate receiving slot 105, the cover plate 106 closes the heat exchange plate receiving slot 105. According to some other specific embodiments of the present invention, the heat exchange plate 102 can be directly laid in the terminal receiving slot 101. When the terminal 5 in the terminal receiving slot 101 is heated, the heat can be dissipated through the heat exchange plate 102, thereby preventing the terminal 5 from overheating.

[0061] like Figures 4 to 8As shown, the first housing 1 includes a main housing 103 and a secondary housing 104. The main housing 103 is connected to the second housing 2, and the secondary housing 104 can slide relative to the main housing 103 in a direction away from the main housing 103 to adjust the size of the terminal receiving slot 101.

[0062] More specifically, the first housing 1 includes a main housing 103 and a secondary housing 104 that are connected to each other. The main housing 103 is connected to the second housing 2, so that the first housing 1 can slide relative to the second housing 2. Figure 7 As shown, the auxiliary housing 104 can be moved in a direction away from the main housing 103 (ie, as shown in FIG. Figure 7 The secondary housing 104 slides relative to the main housing 103 in the second direction (as shown in FIG. 1 ) to adjust the size of the terminal receiving slot 101. Figure 7 When the secondary housing 104 slides relative to the main housing 103 in the direction indicated by the arrow in the second direction shown in FIG. 1 , the terminal receiving slot 101 is elongated, and a larger terminal 5 can be accommodated. Figure 7 When the terminal receiving slot 101 slides relative to the main housing 103 in a direction opposite to the direction indicated by the arrow of the second direction, the terminal receiving slot 101 becomes shorter.

[0063] like Figure 4 and Figure 5 As shown, the main housing 103 is also provided with a camera hole 119, which is adapted to the position, size, shape, and number of the camera module of the terminal 5, so the terminal protective shell does not affect the camera function of the terminal 5. When the cover plate 106 is present, a through hole 120 is provided on the cover plate 106, which is connected to the camera hole 119, and the through hole 120 is adapted to the position, size, shape, and number of the camera module of the terminal 5, thereby avoiding affecting the camera function of the terminal 5.

[0064] like Figures 6 to 10 As shown, according to some specific embodiments of the present utility model, the main housing 103 is provided with a first slide groove 107, and a sliding pin 108 is installed in the first slide groove 107, and the sliding pin 108 can slide in the first slide groove 107. One end of the sliding pin 108 is connected to the first elastic member 109, and the other end of the sliding pin 108 is connected to the auxiliary housing 104.

[0065] More specifically, Figure 8 and Fig. 9 The main housing 103 is shown in abutment with the auxiliary housing 104. The sliding pin 108 can slide in the first slide slot 107. The first elastic member 109 is sleeved on the sliding pin 108, one end of the sliding pin 108 is connected to one end of the first elastic member 109, the other end of the first elastic member 109 is connected to one end surface of the first slide slot 107, and the other end of the sliding pin 108 is connected to the auxiliary housing 104. Figure 7 and Fig.10 The display shows the state where the secondary shell 104 is away from the main shell 103. When the user pulls the secondary shell 104 in the direction indicated by the second direction arrow, the secondary shell 104 will drive the sliding pin 108 to slide in the first sliding groove 107, and the sliding pin 108 will squeeze the first elastic member 109 to produce elastic deformation and thus generate elastic force. At this time, after the user puts the terminal 5 into the terminal accommodating slot 101, the elastic force of the first elastic member 109 causes the main shell 103 and the secondary shell 104 to clamp the terminal 5, and the terminal 5 is not easy to fall off. When the user takes the terminal 5 out of the terminal accommodating slot 101, the elastic force of the first elastic member 109 causes the sliding pin 108 to slide in the direction opposite to that indicated by the second direction arrow, and the sliding pin 108 drives the secondary shell 104 to approach the main shell 103 and return to the state as shown. Figure 8 and Fig. 9 The sliding pin 108 slides in the first sliding groove 107, so it will not interfere with the relative sliding of the first shell 1 and the second shell 2. It can be understood that Figure 8 and Fig. 9 In the illustrated embodiment, the first elastic member 109 is used as a compression spring, so the “connected” manner may be that there is a contact relationship between the two.

[0066] In some feasible embodiments, the first elastic member 109 may not be sleeved on the sliding pin 108. One end of the sliding pin 108 is fixedly connected to one end of the first elastic member 109, and the other end of the first elastic member 109 is fixedly connected to the other end face of the first slide groove 107. When the user pulls the auxiliary shell 104 in the direction indicated by the second direction arrow, the auxiliary shell 104 will drive the sliding pin 108 to slide in the first slide groove 107, and the sliding pin 108 will stretch the first elastic member 109 to deform and generate elastic force. The working principle and effect of the elastic force generated by the first elastic member 109 are similar to those described above and will not be repeated here. It can be understood that in Figure 8 and Fig. 9 In the illustrated embodiment, the first elastic member 109 is used as a tension spring, so the “connection” may be a fixed connection relationship between the two.

[0067] like Figures 7 to 10 As shown, the auxiliary housing 104 is installed with a buckle 110 , and the other end of the sliding pin shaft 108 is buckled with the buckle 110 .

[0068] The buckle 110 can adopt an E-type buckle, a spring snap ring or other structures. During assembly, after inserting the other end of the sliding pin shaft 108 into the sub-shell 104, the buckle 110 is installed to the sub-shell 104 so that the buckle 110 and the other end of the sliding pin shaft 108 are engaged with the buckle 110, thereby realizing the connection between the sliding pin shaft 108 and the sub-shell 104, which is easy to install.

[0069] like Figure 5 , Figure 6 As shown, according to some specific embodiments of the present invention, the main housing 103 is provided with a first magnetic member 111, and the auxiliary housing 104 is provided with a second magnetic member 112. The first magnetic member 111 and the second magnetic member 112 are arranged opposite to each other so that the first magnetic member 111 and the second magnetic member 112 can attract each other.

[0070] More specifically, the first magnetic member 111 and the second magnetic member 112 may both be permanent magnets, or one may be a permanent magnet and the other may be a metal that can be attracted by a permanent magnet. In some specific embodiments, the first magnetic member 111 and the second magnetic member 112 are both permanent magnets, and the south pole of the first magnetic member 111 corresponds to the north pole of the second magnetic member 112. Figure 7 When the secondary housing 104 is away from the main housing 103, the first magnetic member 111 and the second magnetic member 112 can attract each other to help keep the terminal 5 from falling off. Figure 8 In the state where the secondary housing 104 is abutting against the main housing 103, the first magnetic member 111 and the second magnetic member 112 can attract each other so that the main housing 103 and the secondary housing 104 remain in the abutting state. There can be a recess 121 on the main housing 103, which can accommodate the first magnetic member 111 and still maintain the recessed shape after accommodating the first magnetic member 111. Accordingly, the second magnetic member 112 on the secondary housing 104 can be formed as a protrusion protruding from the surface of the secondary housing 104, so that when the main housing 103 and the secondary housing 104 are abutting, the protruding second magnetic member 112 can just extend into the recess 121, ensuring that the main housing 103 and the secondary housing 104 are relatively stable.

[0071] like Figure 6 As shown, according to some specific embodiments of the utility model, the secondary housing 104 is provided with an external interface 113, and the external interface 113 is used to connect to the terminal 5 or an external power source. The external interface 113 can be, for example, a Type-C interface, a LightningDock interface, etc. When the terminal 5 is placed in the terminal receiving slot 101, the external interface 113 can be inserted into the terminal 5 to realize data interaction between the communication module 3 and the terminal 5, or the external interface 113 can also be connected to an external power source to charge the terminal 5 or the terminal protective shell.

[0072] like Fig.11 and Fig.12 , Figures 14 to 16 As shown, according to some specific embodiments of the utility model, the second housing 2 is installed with a slide rail bracket 202, and the two ends of the slide rail bracket 202 are bent to form a slide rail 203. The first housing 1 is provided with a second slide groove 114, and the second slide groove 114 is provided with a side groove 115. The slide rail 203 is slidably matched with the second slide groove 114, and a part of the slide rail 203 is located in the side groove 115.

[0073] More specifically, the slide rail bracket 202 is installed to the second shell 2 through the third connecting member 204, and can also be installed to the second shell 2 by welding, clamping, etc. After the two ends of the slide rail bracket 202 are bent to form the slide rail 203, the slide rail 203 slides with the second slide groove 114, and the slide rail 203 is partially located in the side groove 115, which is equivalent to the slide rail bracket 202 hooking the first shell 1. During assembly, the second shell 2 is pressed toward the first shell 1. Since the two ends of the slide rail bracket 202 are bent to form the slide rail 203, it has a certain elasticity. By utilizing the elasticity of the slide rail bracket 202, the slide rail 203 can be partially inserted into the side groove 115, and the remaining part is located in the second slide groove 114, which is convenient for assembly. By utilizing the sliding of the slide rail 203 in the second slide groove 114, the relative sliding between the first shell 1 and the second shell 2 can be achieved. According to some other embodiments of the present invention, a slide rail can be provided on the first shell 1 and a slider can be provided on the second shell 2, and a sliding connection between the first shell 1 and the second shell 2 can be achieved through the cooperation of the slide rail and the slider.

[0074] like Figures 13 to 27 As shown, according to some specific embodiments of the present invention, the terminal protective shell further includes an elastic structure. The two ends of the elastic structure are rotatably connected to the first shell 1 and the second shell 2 respectively. Fig.23 As shown, the key 201 can also be in an intermediate state between the shielding state and the exposed state. Fig.23 The intermediate state shown in FIG. 1 is switched relative to the second housing 2 by sliding. Fig. 22 The occlusion state shown or Fig.24 In the exposed state shown, the elastic structure applies a first elastic force to the first shell 1 in the same sliding direction as the first shell 1, wherein the deformation amount generated by the elastic structure in the intermediate state is the largest.

[0075] More specifically, when the user pushes the first housing 1 to slide relative to the second housing 2 along the direction indicated by the first direction arrow, the terminal protective shell is Fig. 22 The occlusion state shown reaches Fig.24 During the exposure state shown in Fig.23 The elastic structure is set so that, in the middle state shown in Fig. 22 The occlusion state shown reaches Fig.23 During the intermediate state shown in FIG. 1 , the elastic structure applies a force to the first housing 1 in the opposite direction to the sliding direction of the first housing 1 (in the opposite direction to the direction indicated by the first direction arrow). At this time, the user can feel a pushing resistance. The user continues to push the first housing 1 from FIG. 1 to FIG. 1 . Fig.23 The intermediate state shown in FIG. 1 is switched relative to the second housing 2 by sliding. Fig.24In the exposed state shown in FIG. 1 , the elastic structure applies a first elastic force to the first shell 1 in the same direction as the sliding direction of the first shell 1 (the same direction as the direction indicated by the first direction arrow), and the user can feel a pushing force. The deformation generated by the elastic structure in the intermediate state is the largest. On the contrary, when the user pushes the first shell 1 to slide relative to the second shell 2 in the direction opposite to the direction indicated by the first direction arrow, the terminal protective shell is moved from Fig.24 The exposed state shown reaches Fig. 22 During the shielding state shown in FIG. 1 , the elastic structure is set so that, in the Fig.24 The exposed state shown reaches Fig.23 During the intermediate state shown in FIG. 1 , the elastic structure applies a force to the first shell 1 in the opposite direction to the sliding direction of the first shell 1 (the same direction as the direction indicated by the first direction arrow). At this time, the user can feel a pushing resistance. The user continues to push the first shell 1 to slide relative to the second shell 2 from the intermediate state to the intermediate state. Fig. 22 In the shielding state shown, the elastic structure applies a first elastic force to the first shell 1 in the same direction as the sliding direction of the first shell 1 (opposite to the direction indicated by the first direction arrow), and the user can feel a push force. The deformation generated by the elastic structure in the intermediate state is the largest. The elastic force provided by the elastic structure can prevent the first shell 1 from sliding accidentally with the second shell 2, and keep the terminal protective shell in the shielding state or exposed state required by the user.

[0076] like Figures 13 to 25 As shown, according to a specific embodiment of the utility model, the elastic structure includes a telescopic component 4. The telescopic component 4 includes a first telescopic member 401 and a second telescopic member 402, and the first telescopic member 401 and the second telescopic member 402 are slidably matched. A second elastic member 403 is arranged between the first telescopic member 401 and the second telescopic member 402. A first hole 404 is arranged at one end of the first telescopic member 401, and the first hole 404 is rotatably connected to the first shell 1 through the first connecting member 116. A second hole 405 is arranged at one end of the second telescopic member 402, and the second hole 405 is rotatably connected to the slide rail bracket 202 through the second connecting member 205. The first connecting member 116, the second connecting member 205, and the third connecting member 204 can be rivets, bolts, etc. When the first shell 1 slides relative to the second shell 2, the telescopic component 4 rotates relative to the first shell 1 and the second shell 2, and the first telescopic member 401 slides relative to the second telescopic member 402. When the first housing 1 slides relative to the second housing 2 from the intermediate state to switch to the shielding state or the exposing state, the second elastic member 403 applies a first elastic force in the same sliding direction as the first housing to the first housing 1 .

[0077] like Fig.17 , Figures 19 to 21As shown, according to some specific embodiments provided by the utility model, the elastic structure includes a telescopic assembly 4, and the telescopic assembly 4 includes a first telescopic member 401 and a second telescopic member 402, and the first telescopic member 401 and the second telescopic member 402 are slidably matched. Specifically, the first telescopic member 401 is provided with a cavity, and the partial structure of the second telescopic member 402 can be inserted into the cavity of the first telescopic member 401, so that the length of the entire telescopic assembly 4 can be extended or shortened. A second elastic member 403 is provided between the first telescopic member 401 and the second telescopic member 402, and the second elastic member 403 is provided in the cavity of the first telescopic member 401, and one end of the second elastic member 403 is connected to the inner wall of the cavity of the first telescopic member 401, and the other end of the second elastic member 403 is connected to the second telescopic member 402. During the relative sliding process between the first telescopic member 401 and the second telescopic member 402, the second elastic member 403 can be deformed and provide elastic force. One end of the first telescopic member 401 is provided with a first hole 404, and one end of the second telescopic member 402 is provided with a second hole 405.

[0078] like Fig.14 As shown, the first hole 404 of the telescopic assembly 4 is rotatably connected to the first housing 1 through the first connecting member 116, and the second hole 405 is rotatably connected to the slide rail bracket 202 through the second connecting member 205. When the first housing 1 slides relative to the second housing 2, driven by the slide rail bracket 202, the telescopic assembly 4 rotates relative to the first housing 1 with the first connecting member 116 as the rotating axis, and rotates relative to the slide rail bracket 202 with the second connecting member 205 as the rotating axis, so it also rotates relative to the second housing 2, and the first telescopic member 401 slides relative to the second telescopic member 402.

[0079] like Figures 18 to 24 As shown, when the user pushes the first housing 1 to slide relative to the second housing 2 along the direction indicated by the first direction arrow, the terminal protective shell is Fig. 22 The occlusion state shown reaches Fig.24 During the exposure state shown in Fig.23 The intermediate state shown. Fig.18 In the embodiment, a pair of telescopic components 4 are used, and during the movement of the first housing in the direction indicated by the first direction arrow, the telescopic component 4 is telescoped from the shielding state to the intermediate state and then to the exposed state according to Fig.18The viewing angle changes from top to bottom. In the process of switching from the blocking state to the intermediate state, the telescopic component 4 rotates relative to the first shell 1 and the second shell 2, and the second telescopic member 402 slides relative to the first telescopic member 401 to shorten the length of the entire telescopic component 4, and the second elastic member 403 is stretched. Therefore, the two telescopic components 4 will apply two components of force F01 and F02 to the first shell 1 through the first telescopic member 401 respectively. The resultant force of these two components is F1. At this time, F1 is opposite to the direction indicated by the first direction arrow and is also opposite to the sliding direction of the first shell 1. At this time, the user can feel a pushing resistance. When reaching the intermediate state, the deformation of the telescopic component 4 reaches the maximum, that is, the total length of the telescopic component 4 is the shortest. At this time, the directions of the two components F01 and F02 are opposite and parallel. The user continues to push the first shell 1, and in the process of switching from the intermediate state to the exposed state, the telescopic component 4 continues to rotate, the first telescopic member 401 and the second telescopic member 402 slide relative to each other, and the total length of the telescopic component 4 becomes longer. The second elastic member 403 provides an elastic force to the first shell 1 through the first telescopic member 401 during the process of recovering to the initial length. The elastic component forces provided by the two telescopic components 4 are still marked as F01 and F02, but the directions have changed. Therefore, the direction of the resultant force F2 of the two component forces has also changed. The direction of F2 is the same as the sliding direction of the first shell 1 at this time (that is, the same as the direction indicated by the first direction arrow). At this time, the user can feel a pushing force. In contrast to the above process, when the user pushes the first shell 1 to slide relative to the second shell 2 in the direction opposite to the direction indicated by the first direction arrow, the terminal protective shell is moved from Fig.24 The exposed state shown reaches Fig. 22 During the shielding state shown in the figure, the two telescopic components 4 will first apply elastic forces F01 and F02 to the first shell 1 respectively. The direction of the combined force F2 of F01 and F02 is opposite to the sliding direction of the first shell 1 at this time (that is, the same direction as the first direction arrow). At this time, the user can feel a pushing resistance, and the pushing resistance gradually increases until it reaches the middle state. The deformation of the telescopic component 4 is the largest, the total length is the shortest, and the two component forces F01 and F02 are in opposite and parallel directions, so that the maximum static friction of the two telescopic components 4 is 0. The user continues to push the first shell 1 to slide relative to the second shell 2 from the middle state to switch as shown in the figure. Fig. 22 During the shielding state shown, the telescopic assembly 4 applies an elastic force F1 to the first shell 1 in the same sliding direction as the first shell 1 at this time (ie, opposite to the direction indicated by the first direction arrow), and the user can feel a pushing force.

[0080] It can be known from the above description that when the first shell 1 slides from the intermediate state relative to the second shell 2 to the shielding state, the second elastic member 403 applies an elastic force F1 in the same sliding direction as the first shell 1 to the first shell 1; when the first shell 1 slides from the intermediate state relative to the second shell 2 to the exposed state, the second elastic member 403 applies an elastic force F2 in the same sliding direction as the first shell 1 to the first shell 1. Here, the elastic force in the same sliding direction as the first shell 1 is referred to as the first elastic force. On the contrary, when the first shell 1 slides from the shielding state relative to the second shell 2 to the intermediate state, the second elastic member 403 applies an elastic force F1 in the opposite sliding direction of the first shell 1 to the first shell 1; when the first shell 1 slides from the exposed state relative to the second shell 2 to the intermediate state, the second elastic member 403 applies an elastic force F2 in the opposite sliding direction of the first shell 1 to the first shell 1. The setting of this elastic force of the telescopic component 4 can avoid the occurrence of erroneous sliding between the first shell 1 and the second shell 2, and keep the terminal protective shell in the shielding state or exposed state required by the user. For example, when the user does not need to use the button 201, the telescopic component 4 can keep the terminal protective shell in the shielding state, and the first shell 1 and the second shell 2 will not slide and switch to the exposed state due to gravity; on the contrary, when the user needs to use the button 201, the telescopic component can keep the terminal protective shell in the exposed state, and the first shell 1 and the second shell 2 will not slide and switch to the shielding state due to gravity. In the process of the user pushing the first shell 1, the user can also sense the state of the terminal protective shell according to the elastic force provided by the second elastic member 403 of the telescopic component 4, and can smoothly open the terminal protective shell to the exposed state or close it to the shielding state.

[0081] like Figure 1 , Figure 2 , Fig.26 and Fig. 27 As shown, according to another specific embodiment of the utility model, the elastic structure provided includes a spring piece 6. The spring piece 6 has an elastic portion 601, a first winding portion 603 and a second winding portion 602 respectively located at both ends of the elastic portion 601. Similar to the telescopic assembly 4, the first winding portion 603 is rotatably connected to the first shell 1 through the first connecting member 116, and the second winding portion 602 is rotatably connected to the slide rail bracket 202 through the second connecting member 205. When the first shell 1 slides relative to the second shell 2, the spring piece 6 rotates relative to the first shell 1 and the second shell 2, and the elastic portion 601 is deformed. When the first shell 1 slides relative to the second shell 2 from the intermediate state to the shielding state or the exposed state, the elastic portion 601 applies a first elastic force to the first shell 1 in the same sliding direction as the first shell 1.

[0082] More specifically, if Fig. 27As shown, when the user pushes the first housing 1 to slide relative to the second housing 2 along the direction indicated by the first direction arrow, the terminal protective shell is Figure 1 The occlusion state shown reaches Figure 2 During the exposure process shown in the figure, there is an intermediate state. Fig. 27 In the embodiment, a pair of spring sheets 6 are used, and during the movement of the first housing 1 in the direction indicated by the first direction arrow, the spring sheets 6 are deformed from the shielding state to the intermediate state and then to the exposed state according to Fig. 27 The angle of view changes from top to bottom. In the process of switching from the blocking state to the intermediate state, the spring 6 rotates with the first connecting member 116 and the second connecting member 205 as the rotating axis, thereby rotating relative to the first shell 1 and the second shell 2, and the elastic part 601 is compressed and bent, and the straight-line distance between the first winding part 603 and the second winding part 602 becomes shorter. Therefore, the two springs 6 will apply two force components F01 and F02 to the first shell 1 respectively. The resultant force of these two force components is F1. At this time, F1 is opposite to the direction indicated by the first direction arrow and is also opposite to the sliding direction of the first shell 1. At this time, the user can feel a pushing resistance. When reaching the intermediate state, the deformation amount of the elastic part 601 of the spring 6 reaches the maximum, that is, the straight-line distance between the first winding part 603 and the second winding part 602 is the shortest. At this time, the directions of the two force components F01 and F02 are opposite and parallel. The user continues to push the first shell 1, and in the process of switching from the intermediate state to the exposed state, the spring 6 continues to rotate, the elastic part 601 rebounds, and the straight-line distance between the first winding part 603 and the second winding part 602 becomes longer, so the spring 6 provides an elastic force to the first shell 1. The elastic force components provided by the two springs 6 are still marked as F01 and F02, but the directions have changed. Therefore, the direction of the resultant force F2 of the two force components has also changed. The direction of F2 is the same as the sliding direction of the first shell 1 at this time (that is, the same as the direction indicated by the first direction arrow). At this time, the user can feel a pushing force. In contrast to the above process, when the user pushes the first shell 1 to slide relative to the second shell 2 in the direction opposite to the direction indicated by the first direction arrow, the terminal protective shell is moved from the first shell 1 to the second shell 2. Figure 2 The exposed state shown reaches Figure 1 During the shielding state shown in the figure, the two springs 6 will first apply elastic forces F01 and F02 to the first shell 1 respectively. The direction of the combined force F2 of F01 and F02 is opposite to the sliding direction of the first shell 1 at this time (that is, the same direction as the first direction arrow). At this time, the user can feel a pushing resistance, and the pushing resistance gradually increases until it reaches the middle state, the deformation of the spring 6 is the largest, and the two component forces F01 and F02 are opposite and parallel in direction, so that the maximum static friction of the two springs 6 is 0. The user continues to push the first shell 1 to switch from the middle state to the sliding relative to the second shell 2 as shown in the figure. Figure 1During the shielding state shown, the spring piece 6 applies an elastic force F1 to the first housing 1 in the same sliding direction as the first housing 1 at this time (ie, opposite to the direction indicated by the first direction arrow), and the user can feel a pushing force.

[0083] It can be known from the above description that when the first shell 1 slides from the intermediate state relative to the second shell 2 to switch to the shielding state, the spring 6 applies an elastic force F1 in the same direction as the sliding direction of the first shell 1 to the first shell 1; when the first shell 1 slides from the intermediate state relative to the second shell 2 to switch to the exposed state, the spring 6 applies an elastic force F2 in the same direction as the sliding direction of the first shell 1 to the first shell 1. Here, the elastic force in the same direction as the sliding direction of the first shell 1 is referred to as the first elastic force. On the contrary, when the first shell 1 slides from the shielding state relative to the second shell 2 to switch to the intermediate state, the spring 6 applies an elastic force F1 in the opposite direction to the sliding direction of the first shell 1 to the first shell 1; when the first shell 1 slides from the exposed state relative to the second shell 2 to switch to the intermediate state, the spring 6 applies an elastic force F2 in the opposite direction to the sliding direction of the first shell 1 to the first shell 1. The setting of this elastic force of the spring 6 can avoid the occurrence of erroneous sliding between the first shell 1 and the second shell 2, and keep the terminal protective shell in the shielding state or exposed state required by the user. For example, when the user does not need to use the button 201, the spring 6 can keep the terminal protective shell in the shielding state, and the first shell 1 and the second shell 2 will not slide to the exposed state due to gravity; on the contrary, when the user needs to use the button 201, the spring 6 can keep the terminal protective shell in the exposed state, and the first shell 1 and the second shell 2 will not slide to the shielding state due to gravity. When the user pushes the first shell 1, the state of the terminal protective shell can also be sensed according to the elastic force provided by the spring 6, and the terminal protective shell can be smoothly opened to the exposed state or closed to the shielding state.

[0084] In this paper, the working principle and working process of the elastic structure are described by way of example with two specific embodiments of the telescopic assembly 4 and the spring piece 6. Other structures that can play the same role also belong to the scope of the elastic structure. The number of the telescopic assembly 4 and the spring piece 6 can also be increased or decreased as needed, for example, 3 or 4 telescopic assemblies are used, or only 1 spring piece 6 is used, or 3 or 4 spring pieces 6 are used.

[0085] like Fig.15 As shown, in the exposed state, the elastic structure applies a second elastic force to the first shell 1 so that the slide rail 203 and the stop surface 117 of the second slide groove 114 remain in abutment, or the elastic structure is just in the initial state so that the slide rail 203 and the stop surface 117 of the second slide groove 114 remain in abutment, so as to limit the position of the first shell 1 relative to the second shell 2.

[0086] More specifically, Fig.17and Fig.18 Taking the telescopic component 4 in the figure as an example of an elastic structure, in the exposed state, the second elastic member 403 does not completely recover to the initial length, but a part of the deformation remains. Therefore, the second elastic member 403 continues to apply a second elastic force to the first shell 1. Under the action of the second elastic force, the slide rail 203 and the stop surface 117 remain in abutment, and the first shell 1 cannot continue to slide relative to the second shell 2, thereby limiting the position of the first shell 1 relative to the second shell 2. Alternatively, in the exposed state, the second elastic member 403 is just at the initial length. At this time, although the second elastic member 403 no longer applies a second elastic force to the first shell 1, the first shell 1 will not squeeze the second elastic member 403 to deform it, and the slide rail 203 and the stop surface 117 will also remain in abutment, and the first shell 1 cannot continue to slide relative to the second shell 2, thereby limiting the position of the first shell 1 relative to the second shell 2. Similarly, Fig. 27 The spring piece 6 shown in the figure can also play the role of providing the second elastic force.

[0087] like Fig.14 As shown, according to some specific embodiments provided by the present utility model, the first housing 1 is provided with a first limiting structure 118. Fig.12 As shown, according to some specific embodiments provided by the present utility model, the second housing 2 is provided with a second limiting structure 206. Figure 1 In the shielding state shown, the elastic structure applies a third elastic force to the first housing 1 to keep the first limiting structure 118 and the second limiting structure 206 in contact with each other, so as to limit the position of the first housing 1 relative to the second housing 2. Figure 1 In the shielding state shown, the elastic structure is just in the initial state, so that the first limiting structure 118 and the second limiting structure 206 remain in contact with each other, so as to limit the position of the first shell 1 relative to the second shell 2.

[0088] More specifically, in the specific embodiment provided by the present invention, the first limiting structure 118 can be a groove, and the second limiting structure 206 can be a protrusion, and the limiting is performed by the cooperation between the protrusion and the groove. In other specific embodiments provided by the present invention, the first limiting structure 118 can be a step surface, and the second limiting structure 206 can also be a step surface, and the limiting is performed by the cooperation between the two step surfaces. Fig.17 and Fig.18Taking the telescopic component 4 in the figure as an elastic structure, in the shielding state, the second elastic member 403 does not completely restore to the initial length, but a part of the deformation remains, so the second elastic member 403 continues to apply a third elastic force to the first shell 1. Under the action of the third elastic force, the first limiting structure 118 and the second limiting structure 206 remain in abutment, and the first shell 1 cannot continue to slide relative to the second shell 2, thereby limiting the position of the first shell 1 relative to the second shell 2. Or, in the case of Figure 1 In the shielding state shown, the second elastic member 403 just recovers to its initial length. Although the second elastic member 403 no longer applies a third elastic force to the first shell 1, the first shell 1 will not squeeze the second elastic member 403 to deform it. Therefore, the first limiting structure 118 and the second limiting structure 206 can also maintain contact to limit the position of the first shell 1 relative to the second shell 2. Fig. 27 The spring piece 6 shown in the figure can also play the role of providing a third elastic force.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
