[0002] Mobile terminals (such as mobile phones, tablet computers, personal digital assistants, e-books, etc.) play a very important role in modern life. Therefore, people urgently need protective cases to effectively protect this important tool. The protective case can protect the mobile terminal from damage, thereby extending the service life of the mobile terminal and ensuring the smooth progress of daily life and work. In the related art, most protective cases improve the protection performance by thickening and strengthening, but this design often leads to an overweight shell body and an unattractive appearance. On the contrary, although the protective case with a beautiful and thin appearance is attractive in design, it usually has a poor protection effect and cannot effectively protect the mobile terminal from damage.

[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all 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 protection scope of the present application.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0055] Moreover, in addition to being able to represent an orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to specific circumstances.

[0056] In addition, the terms "install", "set", "provided with", "connect", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can also be internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0057] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0058] In today's digital age, mobile terminals such as smartphones, tablets, PDAs, and e-readers have become an indispensable bridge connecting individuals with the world, and work with life. They not only carry the basic function of communication, but also are a comprehensive platform integrating multiple functions such as entertainment, learning, and office work. Their importance is self-evident. Therefore, how to properly protect these mobile terminal devices from damage caused by accidental drops, scratches, or impacts has become the focus of attention of the majority of users. Currently, the protective cases of most mobile terminals enhance their protective performance by thickening and strengthening, but this design often leads to an overweight shell and an unattractive appearance. On the contrary, although the protective cases with a beautiful and thin appearance are attractive in design, they usually have poor protective effects and cannot effectively protect mobile terminals from damage.

[0059] In addition, when a mobile terminal drops, it drops randomly. Since the camera module usually protrudes from the surface of the mobile terminal, it may cause damage to the camera module of the mobile terminal and the like.

[0060] In view of this, the embodiments of the present application provide a protective case and a mobile terminal, which can protect the camera module of the mobile terminal, thereby protecting the terminal body of the mobile terminal from damage.

[0061] Next, the technical solutions of the present application will be further described in conjunction with the embodiments and the drawings.

[0062] Please refer to Figure 1 and Figure 2 , Figure 1 which are the schematic structural diagrams of the mobile terminal disclosed in the embodiments of the present application, Figure 2 and which are the exploded structural diagrams of the mobile terminal disclosed in the embodiments of the present application. The embodiments of the present application disclose a mobile terminal 200, which includes a terminal body 210 and a protective case 100. Among them, the protective case 100 can be sleeved on the outer periphery of the terminal body 210 to protect the terminal body 210 from damage.

[0063] The terminal body 210 may include, for example, a housing and a display screen. The housing may include, for example, a middle frame and a rear cover. The middle frame and the rear cover are enclosed and connected, and the display screen is connected to the middle frame and the rear cover. Thus, the display screen, the middle frame, and the rear cover jointly define the internal space of the terminal body. This accommodation space can be used to install the functional components of the terminal body, such as a battery, a main board, a microphone, a camera module, a mobile communication module, an audio module, a processor, a universal serial bus (USB) interface, a charging management module, a power management module, a charging interface, a headphone interface, a sensor module, and other functional components such as a subscriber identification module (SIM) card interface.

[0064] The mobile terminal 200 in the present application can be used as a smart phone, for example. Its overall shape is generally rectangular, that is, the overall shape of the outer shell of the terminal body is generally rectangular. Then, the protective case 100 sleeved on the terminal body 210 can also be generally rectangular.

[0065] Of course, as other examples, the mobile terminal can also be other terminals such as a tablet computer or a personal digital assistant.

[0066] Considering that the terminal body 210 usually includes a camera module 220, the camera module 220 can be a rear camera module, for example. The camera module 220 usually protrudes or slightly protrudes relative to the back cover surface of the terminal body 210. In this way, when the terminal body 210 is impacted or dropped, the protruding camera module 220 may be damaged due to these effects, affecting the use of the terminal body 210. Based on this, in the present application, by designing the protective case 100 sleeved on the outer periphery of the terminal body 210, a protection structure 3 (see Figure 5 ) is added inside the protective case 100. The protection structure 3 can be used to protect the camera module 220 correspondingly, so as to reduce the probability that the camera module 220 is damaged due to the above effects.

[0067] To facilitate understanding of the specific structure of the protective case 100, the specific structure of the protective case 100 will be described in detail below with reference to the accompanying drawings.

[0068] Please refer to Figures 3 to 4 , Figure 3 which is a schematic perspective view of the protective case disclosed in the embodiment of the present application, Figure 4 and

[0069] is a rear view of the protective case disclosed in the embodiment of the present application. A protective case 100 disclosed in the embodiment of the present application includes a case body 1, a circuit board 2, and a protection structure 3. The case body 1 is configured to be sleeved on the outer periphery of the terminal body 210 of the mobile terminal 200. The case body 1 has a sandwich space 10 located inside, and the case body 1 is provided with an avoidance hole 20 communicating with the sandwich space 10. The avoidance hole 20 is configured to avoid the camera module 220 of the terminal body 210, and the avoidance hole 20 is used to expose the camera module 220 so that the shooting function of the terminal body 210 can be used normally. Figures 5 to 7 Figure 5 Figure 6 which is a schematic internal structure view of the protective case disclosed in the embodiment of the present application, Figure 7 and Figure 6 is a schematic structure view of the protection structure of the protective case disclosed in the embodiment of the present application, Figure 6Partial enlarged view at position A in the figure. The circuit board 2 and the protection structure 3 are both disposed in the sandwich space 10. The protection structure 3 includes a driving component 31, a first protection component 32, and an inflation component 33. The first protection component 32 includes a first moving member 321 and a first airbag 322. The first moving member 321 is connected to the driving component 31, and the first airbag 322 is disposed on the first moving member 321. The inflation component 33 is connected to the first airbag 322 through a first air tube 331. Wherein, the circuit board 2 is configured to control the driving component 31 to drive the first moving member 321 to move in a direction close to the avoidance hole 20, and to control the inflation component 33 to inflate the first airbag 322 so that the first airbag 322 unfolds.

[0070] A protective case 100 disclosed in an embodiment of the present application, by providing a first moving member 321 and a first airbag 322 that can be movably disposed relative to the sandwich space 10, and the avoidance hole 20 is correspondingly disposed with the camera module 220, and the first airbag 322 can move to the position of the avoidance hole 20 to be inflated and unfolded, thereby buffering the camera module 220 of the terminal body 210, so as to protect the terminal body 210 from being damaged.

[0071] In addition, in the present application, by disposing the above protection structure 3, circuit board 2 and other structures in the sandwich space 10 of the shell body 1, on the one hand, it does not affect the protection of the terminal body 210 by the protective case 100, and on the other hand, it can make the overall appearance of the protective case 100 simple, that is, the protective case 100 can still take into account the protection and the appearance decoration effect.

[0072] Furthermore, since the shell body 1 has a sandwich space 10, that is, the shell body 1 is not entirely a solid structure, therefore, the protective case 100 can retain its lightweight design, which is beneficial to improving the user experience.

[0073] It can be understood that since the protective case 100 needs to charge components such as the circuit board 2, the driving component 31, and the inflation component 33, a battery is configured in the sandwich space 10 to supply power to each component.

[0074] Please refer to again Figure 3 and Figure 4 , considering that the shell body 1 is sleeved outside the terminal body 210, and the terminal body 210 generates heat during operation, and moreover, the circuit board 2 and the protection structure 3 are provided in the sandwich space 10 of the shell body 1, and heat will also be generated during use. Based on this, in some possible implementation manners, at least one of the outer bottom surface 30, the inner bottom surface 40, and the side wall surface 50 of the shell body 1 is provided with a heat dissipation portion 301, and the heat dissipation portion 301 communicates with the sandwich space 10, so that the air in the sandwich space 10 can circulate, and the circuit board 2, the driving component 31, and the terminal body 210 in the sandwich space 10 can be cooled.

[0075] Exemplarily, a heat dissipation portion 301 may be provided on the outer bottom surface 30 of the housing main body 1, or a heat dissipation portion 301 may be provided on the inner bottom surface 40 of the housing main body 1, or a heat dissipation portion 301 may be provided on the side wall surface 50 on one side of the housing main body 1, or a heat dissipation portion 301 may be provided on the side wall surface 50 on the other side of the housing main body 1. Of course, the heat dissipation portion 301 may also be provided on each of the above-mentioned surfaces, and may be specifically set according to actual requirements, and this embodiment does not make specific limitations thereon.

[0076] Optionally, the heat dissipation portion 301 may be provided as one or more. For example, one heat dissipation portion 301 may be provided on the outer bottom surface 30, one heat dissipation portion 301 may be provided on the inner bottom surface 40, and multiple heat dissipation portions 301 may be provided on the side wall surface 50, and may be specifically set according to actual heat dissipation requirements, and this embodiment does not make specific limitations thereon.

[0077] Optionally, the heat dissipation portion 301 may be a heat dissipation filter screen. That is, heat dissipation holes may be provided on the outer bottom surface 30, and then a filter screen may be provided at the heat dissipation holes. While ensuring the heat dissipation inside the protective shell 100, the filter screen can also reduce the risk of external dust and water droplets entering the sandwich space 10.

[0078] It can be understood that the housing main body 1 is provided with a wrapping space for wrapping the terminal body 210. Therefore, the above-mentioned inner bottom surface 40 refers to the inner bottom surface of the wrapping space, and the above-mentioned outer bottom surface 30 refers to the surface opposite to the inner bottom surface 40.

[0079] In some possible implementation manners, at least one side wall surface 50 of the housing main body 1 is provided with a holding portion 501, so as to facilitate the user to hold the mobile terminal 200 during use. Exemplarily, the holding portion 501 may be formed by forming a holding position by recessing on the side surface of the housing main body 1, or a non-slip structure may be directly added to the side surface of the housing main body 1, or a holding position may be formed by recessing on the side surface of the housing main body 1, and at the same time, a non-slip structure may be added to the recessed surface.

[0080] Exemplarily, the non-slip structure may be a non-slip rib, a non-slip bump or a non-slip groove, etc.

[0081] Through the setting of the holding portion 501, when the user uses the terminal body 210, the friction with the protective shell 100 can be increased, preventing the terminal body 210 from falling from the user's hand, and effectively reducing the risk of damage to the terminal body 210 due to dropping.

[0082] Exemplarily, the side wall surface 50 of the housing main body is further provided with a plurality of key slots 502, and the key slots 502 can avoid the volume keys, power-on keys, etc. of the terminal body 210.

[0083] Optionally, the protective case 100 further includes a sensor (not shown), which is electrically connected to the circuit board 2 and configured to detect the current state of the case body 1. For example, when the case body 1 drops, upon detecting that the case body 1 is in a dropped state, the sensor can send a signal to the circuit board 2, so that the circuit board 2 outputs a control signal to the driving component 31 and the inflating component 33 according to the dropped state. Thus, the circuit board 2 controls the driving component 31 to drive the first moving member 321 to move in a direction close to the avoidance hole 20, so that the first moving member 321 approaches the camera module 220 of the terminal body 210, thereby realizing the protection of the camera module 220 by the first airbag 322. At the same time, the circuit board 2 controls the inflating component 33 to inflate the first airbag 322, so that the first airbag 322 inflates and unfolds, thereby buffering and protecting the camera module 220 of the terminal body 210, so as to protect the terminal body 210 from being damaged. Wherein, the sensor can be any one of an accelerometer and a gyroscope, and the present embodiment does not limit this.

[0084] In some possible implementation manners, the protection structure 3 includes an initial state and a dropped state. When the protection structure 3 is in the initial state, the first protection component 32 is located in the middle of the sandwich space 10. In this way, it can be ensured that the center of gravity of the terminal body 210 is still at the center position of the mobile terminal 200, avoiding the risk of increased instability during holding due to the center of gravity shift, which ultimately leads to an increased risk of the terminal body 210 dropping. At the same time, the first protection component 32 is located in the middle of the sandwich space 10, and it can also ensure that the distance for the first protection component 32 to move to any position in the sandwich space 10 is not too far, so that the first airbag 322 can quickly move to the corresponding position, thereby effectively protecting the terminal body 210. In addition, when the protection structure 3 is in the dropped state, the first protection component 32 quickly moves to the avoidance hole 20, so that the first protection component 32 correspondingly protects the camera module 220 of the terminal body 210, avoiding damage to the camera module 220 when the terminal body 210 drops.

[0085] It can be understood that when the terminal body 210 is in a normal use state, the protection structure 3 is in an initial state, and the first protection component 32 is arranged at the middle position of the sandwich space 10. At this time, the camera module 220 of the terminal body 210 corresponds to the avoidance hole 20 and is not blocked by the housing body 1, ensuring the normal use of the function of the camera module 220. When the terminal body 210 falls from a height, the protection structure 3 needs to move to the designated position in the falling state. At this time, the circuit board 2 detects the falling signal sent by the sensor, and the circuit board 2 outputs a control signal to the driving component 31 and the inflating component 33, so that the driving component 31 drives the first moving part 321 to move to the avoidance hole 20, and the inflating component 33 inflates the first airbag 322. The time of this process is very short. Therefore, the first protection component 32 is arranged at the middle position of the sandwich space 10, and the distance for the first protection component 32 to move to any position in the sandwich space 10 is also short. In this way, the first protection component 32 can move to the avoidance hole 20 relatively quickly within a very short time during the fall, realizing the protection of the camera module 220 of the terminal body 210 by the first airbag 322.

[0086] Please refer to Figure 6 and Figure 7 , in some embodiments, the first moving part 321 is provided with a hollow part 3211, and the first airbag 322 is arranged on the first moving part 321 and located on the outer periphery of the hollow part 3211. When the first moving part 321 moves to the avoidance hole 20, the hollow part 3211 communicates with the avoidance hole 20 to avoid the camera module 220. In this way, the avoidance hole 20 can realize the normal use of the camera module 220, and the hollow part 3211 communicates with the avoidance hole 20 correspondingly, realizing that the camera module can be surrounded by the first airbag 322 for protection during the fall, and at the same time, the camera module 220 can also be ensured not to be blocked to ensure the normal use of the camera module 220.

[0087] Exemplarily, there are two first air pipes 331. The two first air pipes 331 are arranged on both sides of the first moving part 321 and connected to the first airbag 322, so that the first airbag 322 inflates and expands more quickly, enabling the camera module 220 of the terminal body 210 to be protected quickly when the terminal body 210 falls. Of course, as other examples, the first air pipe 331 can also be one, three or more.

[0088] In some embodiments, a first mounting groove 3212 is provided on the first moving member 321. The first mounting groove 3212 is located on the outer periphery of the hollowed-out portion 3211 and communicates with the sandwich space 10. The first airbag 322 is disposed in the first mounting groove 3212. The first mounting groove 3212 is used to receive the first airbag 322 within the first moving member 321, so that the first moving member 321 can drive the first airbag 322 to approach the camera module 220 of the terminal body 210, and can also cause the first airbag 322 to be inflated and deployed in the sandwich space 10 to protect the camera module 220.

[0089] In some embodiments, the driving assembly 31 includes a driving member 311 and a first transmission member 312. The driving member 311 is in transmission connection with the first transmission member 312, and the first moving member 321 is connected to the first transmission member 312, so that the driving member 311 drives the first transmission member 312 to rotate, and the first transmission member 312 drives the first moving member 321 to move in a direction close to the avoidance hole 20. In this way, the first moving member 321 can be controlled by the driving member 311 to approach the camera module 220 of the terminal body 210, so that the first airbag 322 provided on the first moving member 321 can protect the camera module 220.

[0090] Exemplarily, the first transmission member 312 includes a first screw 3121. The first screw 3121 is in transmission connection with the driving member 311. An internal thread (not shown) is provided on the first moving member 321, and the first screw 3121 is in threaded connection with the first moving member 321. Thus, the driving member 311 rotates to drive the first screw 3121 to rotate, so that the first moving member 321 can move along the axial direction of the first screw 3121, that is, move in a direction close to the avoidance hole 20. Among them, the thread transmission can evenly distribute the pressure of the connection between the first screw 3121 and the first moving member 321, thereby increasing the stability of their connection.

[0091] Please refer to Figure 5 and Figure 8 , Figure 8 for Figure 6The partial enlarged view at position B in the [description]. Optionally, the protection structure 3 further includes a second protection component 34. The second protection component 34 is disposed in the sandwich space 10. The second protection component 34 includes a second airbag 341. The second airbag 341 is disposed near the corner 101 of the shell body 1, so as to protect the corner 101 of the terminal body 210 when the terminal body 210 falls. The inflation component 33 is further configured to inflate the second airbag 341 through the second air tube 332, so that the second airbag 341 expands. In the normal use state, the second airbag 341 is in the sandwich space 10, while in the falling state, the inflation component 33 can be used to inflate the second airbag 341, so that the second airbag 341 expands, thereby protecting the corner 101 of the terminal body 210. That is to say, the protective shell 100 of the present application can not only protect the camera module 220, but also protect the corner 101 of the terminal body 210, so as to achieve all-round drop protection for the terminal body 210.

[0092] Optionally, the inflation timing of the inflation component 33 for the second airbag 341 is the same as the inflation timing of the inflation component 33 for the first airbag 322. At this time, since the inflation component 33 inflates the first airbag 322 and the second airbag 341 at the same time, the control steps of the circuit board for the inflation component 33 can be effectively simplified, and only one signal instruction is required to control the inflation of the first airbag 322 and the second airbag 341 at the same time. Moreover, when the circuit board 2 receives the drop signal, the circuit board 2 needs to quickly give a signal instruction to control the inflation component 33, effectively preventing the height of the terminal body 210 from being too high or the drop time being too fast when the terminal body 210 falls, resulting in the first airbag 322 or the second airbag 341 not being inflated and expanded in time, and not being able to protect the terminal body 210, thereby damaging the terminal body 210. Among them, the inflation component 33 further includes an air valve 333. The first air tube 331 and the second air tube 332 can be connected, so that only one air valve 333 can be used to inflate multiple airbags, thereby saving the sandwich space 10 of the protective shell 100, and effectively reducing the overall weight and manufacturing cost of the protective shell 100.

[0093] Optionally, the inflation timing of the inflation component 33 by the circuit board 2 is also the same as the driving timing of the driving component 31. That is to say, the circuit board 2 can simultaneously give command signals to the driving component 31 and the inflation component 33 at the first time when the terminal body 210 falls. Because the falling speed of the terminal body 210 is very high and the time is very short when the terminal body 210 falls, if the inflation timing of the inflation component 33 is the same as the driving timing of the driving component 31, it can be realized that when the protective shell 100 touches the ground, both the first airbag 322 and the second airbag 341 reach the set positions, and the inflation operations of the first airbag 322 and the second airbag 341 are quickly completed, so as to protect the terminal body 210 and avoid damage to the terminal body 210.

[0094] Please refer to again Figure 8 Optionally, the housing body 1 is provided with a communication hole 1011 at the corner 101, and the communication hole 1011 communicates with the interlayer space 10. The second protection component 34 further includes a second moving member 342. The second airbag 341 is disposed on the second moving member 342. The second moving member 342 is configured to be movably disposed in the interlayer space 10 to drive the second airbag 341 to move in a direction close to the communication hole 1011, so that the second airbag 341 can be deployed at the communication hole 1011. The communication hole 1011 provides an outlet for the second moving member 342 to extend out of the terminal body 210 from the interlayer space 10, so that the second moving member 342 can extend out of the interlayer space 10 with the second airbag 341, that is, the second airbag 341 moves from the interlayer space 10 to the corner 101 of the terminal body 210, thereby protecting the corner 101 of the terminal body 210.

[0095] Optionally, the second protection component 34 further includes a limiting rod 345. The limiting rod 345 is disposed on the second moving member 342 to prevent the second moving member 342 from rotating relative to the interlayer space 10, and to avoid the situation that the second moving member 342 rotates relative to the interlayer space 10 when the second screw 3424 rotates, which hinders the subsequent reset of the second moving member 342.

[0096] Optionally, the driving component 31 further includes a second transmission member 313. The second transmission member 313 is in transmission connection with the driving member 311, and the second moving member 342 is connected to the second transmission member 313. The driving member 311 can drive the second transmission member 313 to rotate, so that the second moving member 342 drives the second airbag 341 to move in a direction close to the communication hole 1011. Since the second airbag 341 is disposed in the interlayer space 10 during normal use of the terminal body 210, the possibility of damage to the second airbag 341 can be reduced. At the same time, the second airbag 341 is disposed in the interlayer space 10. Compared with setting an airbag outside the protective case 100, the design of the protective case 100 is more lightweight and compact, and can effectively improve the aesthetics of the protective case 100. In addition, when the terminal body 210 falls, the circuit board controls the driving member 311 to rotate, so that the second moving member 342 drives the second airbag 341 to move in a direction close to the communication hole 1011, realizing the protection of the corner 101 of the terminal body 210 by the second airbag 341, and effectively and reasonably protecting the terminal body 210. Such a design can effectively protect the terminal body 210 while ensuring the aesthetic degree of the protective case 100.

[0097] Among them, the first transmission member 312 and the second transmission member 313 rotate synchronously. Since the driving member 311 is connected to the first transmission member 312 by transmission, and the driving member 311 is connected to the second transmission member 313 by transmission, on the one hand, the driving member 311 can realize the synchronous rotation of the first transmission member 312 and the second transmission member 313, so that the protective shell 100 can react to the first moving member 321 and the second moving member 342 at the moment of falling, so as to realize the protective effect of the protective shell 100 on the terminal body 210. On the other hand, since the terminal body 210 is a portable device, its size will be designed to be relatively small and light, and the volume of the terminal body 210 will not be very large, so that the interlayer space 10 inside the protective shell 100 is also small. At this time, one driving member 311 can realize the synchronous rotation of the first transmission member 312 and the second transmission member 313, and the control of multiple angles is realized through one power source. Such a design can effectively save the use space, reduce the overall weight of the protective shell 100, and effectively reduce the production cost.

[0098] Please also read Figure 6 and Figure 7 Optionally, there are four second protection components 34, and the four second protection components 34 are respectively arranged at four corners 101 close to the interlayer space 10. Since the falling direction of the terminal body 210 is random when it falls, protecting the four corners 101 of the terminal body 210 can protect the terminal body 210 to a greater extent and reduce the possibility of damage to the terminal body 210.

[0099] In addition, the second transmission member 313 includes two transmission rods 3131 and two transmission belts 3132, and both ends of the transmission rods 3131 are provided with driving gears 3131a, and each second moving member 342 is correspondingly provided with a driven gear 3423. In this way, the two ends of one transmission rod 3131 are respectively connected to the two second moving members 342 located on one side of the shell body 1, and the two ends of another transmission rod 3131 are respectively connected to the two second moving members 342 located on the other side of the shell body 1, so that each driving gear 3131a on the transmission rod 3131 is meshed with the corresponding driven gear 3423. At this time, the rotation of one transmission rod 3131 can simultaneously control the two moving members on the same side to move to the corresponding corner 101, which can effectively reduce the design difficulty and design cost, and save the use of the interlayer space 10.

[0100] Wherein, two ends of a transmission belt 3132 are respectively connected to a transmission rod 3131 and a driving member 311, and two ends of another transmission belt 3132 are respectively connected to another transmission rod 3131 and the driving member 311. Thus, the driving member 311 can drive the two transmission belts 3132 to synchronously transmit, so that the two transmission belts 3132 drive the corresponding transmission rods 3131 to rotate. On the one hand, the transmission structure in which the transmission belt 3132 drives the transmission rod 3131 to rotate is relatively simple, which reduces the manufacturing cost and installation difficulty, and is also convenient for the maintenance and replacement of the protection structure 3. On the other hand, when the transmission belt 3132 drives the transmission rod 3131 to rotate, the transmission belt 3132 itself has good elasticity and can mitigate the impact and absorb the vibration when the terminal body 210 drops, thereby reducing the impact on the entire driving assembly 31 and ensuring that the function of the protection structure 3 can be normally realized.

[0101] Furthermore, the driving member 311 can synchronously drive the two transmission belts 3132 to transmit, so that the two transmission rods 3131 synchronously drive the four second moving members 342 to respectively move along the corresponding corners 101, effectively improving the moving synchronism of the driving member 311 for the four second moving members 342, and avoiding any one of the second moving members 342 not moving to the corresponding position due to the inconsistent signal control speed of the driving member 311, resulting in any one of the second airbags 341 not moving to the corner 101 position of the protective shell 100, thus losing the protection effect on the terminal body 210 and causing damage to the terminal body 210.

[0102] Exemplarily, the second moving member 342 is provided with a second screw rod 3424, one end of the second screw rod 3424 is provided with a driven gear 3423, the second moving member 342 is provided with a second installation groove 3421, the second airbag 341 is arranged in the second installation groove 3421, the second installation groove 3421 is provided with an internal thread (not shown), the second screw rod 3424 is threadedly connected to the second installation groove 3421, and the driven gear 3423 on the second screw rod 3424 meshes with the driving gear 3131a of the transmission rod 3131, so that the transmission rod 3131 drives the second screw rod 3424 to rotate, so that the second airbag 341 in the second installation groove 3421 moves towards the corner 101 of the sandwich space 10, thereby realizing the protection of the corner 101 of the terminal body 210. Among them, the screw transmission can evenly distribute the pressure between the second screw rod 3424 and the second moving member 342, thereby increasing the connection stability between the two, and the structural design of the screw transmission is simple, which can effectively reduce the cost.

[0103] Please refer to Figure 8 and Figure 9 , Figure 9This is a front view of the protective case disclosed in the embodiments of the present application when it is in a dropped state. In some embodiments, the second protection component 34 further includes a shock-absorbing member 343 and an elastic member 344. The shock-absorbing member 343 is movably disposed in the communication hole 1011. The shock-absorbing member 343 can move under the movement of the second moving member 342 to expose at least a part of the communication hole 1011, so that the second moving member 342 can move to the communication hole 1011, enabling the second airbag 341 on the second moving member 342 to extend from the sandwich space 10. Subsequently, the second airbag 341 is inflated and deployed to protect the corner 101 of the terminal body 210.

[0104] In addition, two ends of the elastic member 344 are respectively connected to the second moving member 342 and the shock-absorbing member 343. The elastic member 344 can make the shock-absorbing member 343 reset relative to the communication hole 1011. In this way, after the shock-absorbing member 343 pops out during a drop, it can reset back to the communication hole 1011 again. In addition, a damper (not shown) is provided on the elastic member 344, which can achieve an effective shock-absorbing effect when the shock-absorbing member 343 contacts the ground, improving the protection effect on the terminal body 210.

[0105] Optionally, the shock-absorbing member 343 can be set to be adapted to the shape of the communication hole 1011 to be fastened at the communication hole 1011. The elastic member 344 can include, but is not limited to, springs, shrapnel, silicone parts, etc.

[0106] The following briefly describes the protection process when the mobile terminal 200 drops during use:

[0107] During the normal use of the mobile terminal 200, the shell main body 1 of the protective case 100 is sleeved on the outer periphery of the terminal body 210 of the mobile terminal 200 for use. At this time, the protection structure 3 is in an initial state. The first protection component 32 is located in the middle of the sandwich space 10, and the second protection component 34 is arranged at a position in the sandwich space 100 close to the corner 101. Both the first protection component 32 and the second protection component 34 are arranged in the sandwich space 10. In this way, it can not only ensure the normal daily use of the terminal body 210, but also make the overall appearance of the protective case 100 simple.

[0108] When the mobile terminal 200 is impacted or dropped, the mobile terminal 200 is in a dropped state at this time. The protection structure 3 needs to move to the specified position in the dropped state as soon as possible. Since in the initial state, both the first protection component 32 and the second protection component 34 are set as close to the specified position as possible. Therefore, after the circuit board 2 detects the dropped signal sent by the sensor, the circuit board 2 outputs a control signal to the driving component 31 and the inflating component 33, so that the driving component 31 drives the first moving member 321 to move to the avoidance hole, and the driving component 31 drives the second moving member 342 to move to the corner 101 of the corresponding sandwich space 101. At the same time, the inflating component 33 inflates the first airbag 322 and the second airbag 341 to protect the camera module 220 and the corner 101 of the terminal body 210.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
