Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, fig. 1 is an exploded view of an end system according to an embodiment of the present application, fig. 2 is a front schematic view of the end system shown in fig. 1, and fig. 3 is a back schematic view of the end system shown in fig. 1. The terminal system 000 may include: a terminal device 100 and a protective case 200. Here, the protective case 200 may be sleeved on the terminal device 100.

The terminal device 100 in the terminal system 000 may be any product or component having a front-end shooting function, such as a mobile phone, a tablet computer, a notebook computer, a camera, and the like. Fig. 1 is a schematic illustration of a mobile phone as an example of a terminal device. The front side of the terminal device 100 refers to the side of the terminal device 100 on which the display screen a is provided, and the back side of the terminal device 100 refers to the side of the terminal device 100 on which the battery cover B is provided.

Here, the terminal device 100 may have the sensor 101 and the flash 102, and both the sensor 101 and the flash 102 may be distributed on the back surface of the terminal device 100. In this application, the terminal device 100 may also generally have a front camera C and a rear camera D. The front camera C may be distributed on the front surface of the terminal device 100, and the rear camera D may be distributed on the rear surface of the terminal device 100. It should be noted that, the flash 102 in the terminal device 100 can supplement light for the rear camera D, so that shooting with the rear camera D in the terminal device 100 in a dim environment is better. The terminal device 100 can implement the corresponding function through the sensor 101. For example, when the sensor 101 is a light sensor, the terminal device 100 may determine the intensity of ambient light of the external environment through the light sensor to control the display brightness of the display screen a according to the intensity of the ambient light.

The protective case 200 in the terminal system 000 may include: a protective housing 201, a support 202, a light supplementing assembly 203 and a shielding assembly 204. It should be noted that, the light supplementing assembly 203 and the shielding assembly 204 are not shown in fig. 1 to 3, and the light supplementing assembly 203 and the shielding assembly 204 will be illustrated in subsequent drawings (for example, fig. 6).

The case body 201 of the case 200 is used to be coupled to the terminal device 100. Here, the protective case body 201 may be coupled to the terminal device 100 from the back of the terminal device 100, and protection can be provided to the terminal device 100 by the protective case body 201.

The support 202 in the protective case 200 can be slidably connected to the protective case body 201. Here, after the support 202 slides with respect to the protective case body 201, the support 202 may be in the first position or the second position. As an example, as shown in fig. 4, fig. 4 is a schematic view of a support frame in a protective case provided in an embodiment of the present application in a first position, when the support frame 202 slides relative to the protective case 201 and is in the first position, a portion of the support frame 202 protrudes from the protective case 201; as shown in fig. 5, fig. 5 is a schematic diagram of the support frame in the protective case provided in the embodiment of the present application in the second position, when the support frame 202 slides relative to the protective case 201 and is in the second position, the support frame 202 does not protrude from the protective case 201, that is, the orthographic projection of the support frame 202 on the protective case 201 may be located in the protective case 201.

For a clearer view of the structure of the protective case 200 on the supporting frame 202, please refer to fig. 6, fig. 6 is a schematic structural diagram of a supporting frame according to an embodiment of the present application. The light supplementing assembly 203 and the shielding assembly 204 in the protective housing 200 may be disposed on a side of the support frame 202 near the protective housing body 201. Here, when the support 202 slides relative to the protective housing 201, the support 202 may drive the light compensating assembly 203 and the shielding assembly 204 to slide synchronously.

In the embodiment of the present application, when the support frame 202 in the protective case 200 slides relative to the protective case body 201 to the first position protruding from the protective case body 201, the shielding component 204 in the protective case 200 may cover the sensor 101 in the terminal device 100, and the terminal device 100 may control the flash 102 to emit light to the light supplementing component 203 in the protective case 200. When the support frame 202 in the protective case 200 slides relative to the protective case body 201 to the second position that does not protrude from the protective case body 201, the shielding member 204 in the protective case 200 can be separated from the sensor 101 in the terminal device 100, and the terminal device 100 can control the flash 102 to stop emitting light.

By way of example, as shown in fig. 6, the light supplementing assembly 203 in the protective case 200 may include: a light guide structure 2031 and a light supplementing plate 2032. Fig. 7 is a schematic structural diagram of a terminal system when a support frame in a protective housing is in a first position according to an embodiment of the present application. When the support frame 202 in the protective housing 200 slides to the first position, a portion of the support frame 202 protrudes from the protective housing body 201, and the light compensating plate 2032 in the light compensating assembly 203 may be disposed on the portion of the support frame 202 protruding from the protective housing body 201. Further, the light guide structure 2031 in the light supplementing assembly 203 may be provided at a position opposite to the flash 102 in the support frame 202 at the first position. Thus, when the support frame 202 in the protective case 200 slides to the first position, the light guide structure 2031 can cover the flash 203, and the light supplementing plate 2032 protrudes from the protective case body 201.

Here, the shielding assembly 204 may be provided in the support frame 202 in the first position at a position opposite the sensor 101, and it is also necessary to ensure that the shielding assembly 204 in this position is able to be displaced from the sensor 101 when the support frame 202 is in the second position. In this way, when the support frame 202 in the protective case 200 is slid to the first position, the blinder assembly 204 on the support frame 202 can cover the sensor 101; when the support frame 202 in the protective housing 200 is slid to the second position, the blinder assembly 204 on the support frame 202 can be separated from the sensor 101, i.e., the sensor 101 is not covered by the blinder assembly 204.

Again, since the first signal acquired by the terminal device 100 through the sensor 101 covered by the blanking member 204 is different from the second signal acquired by the sensor 101 not covered by the blanking member 204. Thus, when the terminal device 100 acquires the first signal via the sensor 101, the terminal device 100 can determine that the sensor 101 has been covered by the cover assembly 204 and can further determine that the support frame 202 has been slid to the first position. At this time, the terminal device 100 may control the flash 101 to light, and the light emitted from the flash 101 may be directed to the light guide structure 2031 in the light supplementing assembly 203, and the light guide structure 2031 may guide the light emitted from the flash 101 to the light supplementing plate 2032, so that the light supplementing plate 2032 may emit light in a direction away from the support frame 202.

When the terminal device 100 acquires the second signal via the sensor 101, the terminal device 100 may determine that the sensor 101 is not covered by the cover assembly 204, and may further determine that the support 202 has been slid to the second position. At this time, the terminal device 100 can control the flash 101 to be turned off, and thus can ensure that the light supplementing plate 2032 does not emit light outward.

For example, when a user needs to use the front camera C of the terminal device 100 to shoot in a dim environment, the user only needs to push the support frame 202 in the protective housing 200 to the first position, and the flash 102 in the terminal device 100 can be automatically turned on, so that the light emitted by the flash 102 can be guided to the light compensating plate 2032 through the light guiding structure 2031, and the light compensating plate 2032 protrudes out of the protective housing body 201. Therefore, the light supplementing plate 2032 can emit light toward the front of the terminal device 100 to provide light supplementing for the front camera C of the terminal device 100, so as to ensure that the photographing effect of the front camera C in a dim environment is better. When the user no longer uses the front camera C of the terminal device 100 to shoot, the user only needs to push the support 202 in the protective case 200 to the second position, and the flash 102 in the terminal device 100 can be automatically turned off.

In addition, after the shielding component 204 is arranged at the corresponding position of the supporting frame 202 in the protective shell 200, the terminal device 100 can determine the position of the supporting frame 202 after sliding by using the sensor 101, so that the terminal device 100 can control the flash lamp 201 to be turned on or off according to the position of the supporting piece 201. There is no need to provide a separate sensor for detecting the position of the support frame 202 after sliding on the protective case 200. In addition, the sensor 101 of the terminal device 100 itself is not a sensor exclusively used for detecting the position of the support frame 202, but the sensor 101 is provided for the terminal device 100 to have a certain function. Here, using such a sensor 101 not only enables the terminal device 100 to perform a corresponding one of the functions, but also enables the position of the support frame 202 to be detected. In this way, the structure of the terminal system 000 can be effectively simplified.

To sum up, the protective case provided in the embodiment of the present application includes: protective housing body, support frame, light filling subassembly and shelter from subassembly. The protective housing body can cup joint on terminal equipment. When the user needs to shoot with the front-end camera of terminal equipment in dim environment, the user only needs to promote the support frame in the protective housing to first position, and the flash light in the terminal equipment just can light automatically for the light that the flash light was emergent can pass through the light guide structure in the light filling subassembly and lead the light filling board in the light filling subassembly, and the light filling board in the light filling subassembly can bulge in protective housing body. Therefore, the light supplementing plate can emit light towards the front side of the terminal equipment so as to provide light supplementing for the front-mounted camera of the terminal equipment, and further ensure that the shooting effect of the front-mounted camera in a dim environment is good. When the user does not use the front camera of the terminal device to shoot any more, the user only needs to push the support frame in the protective shell to the second position, and the flash lamp in the terminal device can be automatically extinguished. In addition, after the shielding component is arranged at the corresponding position of the supporting frame in the protective shell, the terminal equipment can determine the position of the supporting frame after sliding by utilizing the sensor of the terminal equipment, so that the terminal equipment can control the flash lamp to be on or off according to the position of the supporting piece. The structure of the terminal equipment can be effectively simplified without arranging a sensor which is independently used for detecting the sliding position of the supporting frame on the protective shell.

Alternatively, as shown in fig. 8, fig. 8 is a top view of a terminal device provided in an embodiment of the present application. The terminal device 100 also has a decorative component 103. Here, the decoration member 103 may be generally located at the rear surface of the terminal device 100, and the decoration member 103 may be used to decorate the rear camera D of the terminal device 100. Wherein the flash 102 of the terminal device 100 may be distributed over the decoration element 103.

In the present application, as shown in fig. 9 and 10, fig. 9 is a schematic back view of another terminal system provided in an embodiment of the present application, and fig. 10 is a schematic back view of yet another terminal system provided in an embodiment of the present application. Fig. 9 is a schematic view of the support frame 202 of the protective case 200 in the terminal system 000 in the first position, and fig. 10 is a schematic view of the support frame 202 of the protective case 200 in the terminal system 000 in the second position. The support bracket 202 in the protective case 200 may have a first opening K1 to mate with the decoration device 103. When the support frame 202 in the protective case 200 is slid to the second position, the decoration device 103 of the terminal device 100 is located in the area surrounded by the first opening K1 of the support frame 202. In this way, it is ensured that the support 202 does not block the rear camera D of the terminal device 100 and the flash 102 for supplementing light to the rear camera D when the support 202 is in the second position.

The case body 201 in the case 200 has a second opening K2 communicating with the first opening K1, for example. Here, after the protective case body 201 is sleeved on the terminal device 100, the second opening K2 of the protective case body 201 may be distributed around the decoration member 103 of the terminal device 100. It should be noted that, the decoration device 103 is generally protruded from the battery cover of the terminal device 100, and for this purpose, after the protection housing body 201 is sleeved on the terminal device 100, the decoration device 103 is embedded into the second opening K2 of the protection housing body 201. When the support frame 202 is in the second position, the boundary of the first opening K1 of the support frame 202 may completely coincide with the boundary of the second opening K2 of the protective housing 201, or the boundary of the second opening K2 of the protective housing 201 is located in the first opening K1 of the support frame 202, so as to ensure that the decoration device 103 can be located in the area surrounded by the first opening K1 of the support frame 202.

In the embodiment of the present application, as shown in fig. 11, fig. 11 is a schematic structural view of another support frame provided in the embodiment of the present application. The light guide structure 2031 in the light supplementing assembly 200 provided on the support frame 202 may include: a first light guide 2031a and a second light guide 2031b. Here, both ends of the second light guide 2031b may be connected with the first light guide 2031a and the light supplementing plate 2032 in a distributed manner. And the light supplementing plate 2032 and the first light guide 2031a may be disposed on two first sides of the first opening K1 opposite to each other, respectively.

Wherein the first light guide 2031a in the light guide structure 2031 may cover the flash 101 of the terminal apparatus 100 when the support frame 202 in the protective case 200 is slid to the second position. Thus, the light emitted from the flash 101 may be directed to the first light guide 2031a, and the first light guide 2031a may guide the light to the second light guide 2031b, and then the second light guide 2031b may guide the light to the light compensating plate 2032.

In the embodiment of the present application, the types of the sensors 101 of the terminal device 100 are various, and the structures of the shielding members 204 corresponding to the different types of the sensors 101 are also different. For this purpose, the embodiments of the present application will be described by taking the following three alternative implementation manners as examples:

in a first alternative implementation, as shown in fig. 11 and 12, fig. 12 is a top view of a terminal device mated with the support shown in fig. 11. The sensor 101 in the terminal device 100 is a magnetic induction sensor 101a. The magnetic induction sensor 101a is a sensitive element capable of sensing the external magnetic field intensity and outputting an electric signal according to the external magnetic field intensity, for example. Here, when the intensity of the external magnetic field is stronger, the amplitude of the electric signal output by the magnetic induction sensor 101a is higher; conversely, the lower the intensity of the external magnetic field, the lower the amplitude of the electric signal output by the magnetic induction sensor 101a.

In this case, the shielding assembly 204 in the protective case 200 is a magnet 204a. Thus, when the support 202 slides to the first position, the magnet 204a covers the magnetic induction sensor 101a, so that the magnetic induction sensor 101a can output an electrical signal with a higher amplitude, and the terminal device 100 can determine that the support 202 has slid to the first position through the electrical signal output by the magnetic induction sensor 101a, and at this time, the terminal device 100 can control the flash lamp 102 to be turned on. When the support 202 slides to the second position, the magnet 204a is separated from the magnetic induction sensor 101a, so that the magnetic induction sensor 101a can output an electrical signal with a lower amplitude, and the terminal device 100 can determine that the support 202 has slid to the second position through the electrical signal output by the magnetic induction sensor 101a, and at this time, the terminal device 100 can control the flash lamp 102 to be turned off.

Alternatively, the magnetic induction sensor 101a is typically disposed outside the decoration member 103, and the magnetic induction sensor 101a may be disposed close to the decoration member 103, the magnetic induction sensor 101a being capable of being packaged by the battery cover B of the terminal device 100. For this purpose, the position of the magnet 204a on the support 202 can be designed by the position of the magnetic induction sensor 101a. For example, the magnet 204a and the second light guide 2031b may be disposed at two second sides of the first opening K1, respectively, which are disposed opposite to each other.

It should be noted that, the magnetic induction sensor 101a in the terminal device 100 can not only cooperate with the magnet 204a to detect the position of the support 202, but also enable the terminal device 100 to sense the magnetic field of the earth through the magnetic induction sensor 101a, so that the terminal device 100 can realize the function of a compass.

In a second alternative implementation manner, as shown in fig. 13 and 14, fig. 13 is a schematic structural diagram of another support frame provided in an embodiment of the present application, and fig. 14 is a top view of a terminal device mated with the support frame shown in fig. 13. The sensor 101 in the terminal device 100 is a light sensor 101b. Here, the light sensors 101b may be generally distributed on the decoration device 103. The light sensor 101b is a sensing element capable of sensing the intensity of external light and outputting an electric signal according to the intensity of external light, for example. Here, when the intensity of the external light is stronger, the amplitude of the electric signal output through the light sensor 101b is higher; conversely, the lower the intensity of the external light, the lower the amplitude of the electric signal output through the light sensor 101b.

In this case, when the support 202 slides to the first position, the shielding component 204 covers the light sensor 101b, so that the light sensor 101b can no longer receive the light in the external environment, and further the amplitude of the electrical signal output by the light sensor 101b can suddenly decrease, and at this time, the terminal device 100 can control the flash 102 to be turned on. When the support 202 slides to the second position, the shielding component 204 does not cover the light sensor 101b any more, so that the light sensor 101b can receive the light in the external environment again, and further the amplitude of the electric signal output by the light sensor 101b can suddenly rise, and at this time, the terminal device 100 can control the flash 102 to be extinguished.

After the light sensor 101b is covered by an external object (e.g., a finger of a user), the amplitude of the electric signal output from the light sensor 101b may suddenly decrease. To ensure that the terminal device 100 is able to determine the accuracy of the position of the support 202 by the light sensor 101b, the shielding assembly 204 in the protective housing 200 may be an auxiliary light guide 204b connected to the first light guide 2031a facing away from the second light guide 2031b.

In one possible scenario, after the light sensor 101b is covered by the external object, if the light sensor 101b is covered by the auxiliary light guide 204b, the support frame 202 will be at the first position, and the light in the external environment will be guided to the light sensor 101b through the light supplementing plate 2032, the second light guide 2031b, the first light guide 2031a and the auxiliary light guide 204b in order, so that the amplitude of the electrical signal output by the light sensor 101b will increase again. If the light sensor 101b is covered by another external object, the amplitude of the electric signal output by the light sensor 101b will not change any more.

In this case, if the terminal device 100 determines that the amplitude of the electric signal output from the light sensor 101b suddenly decreases and then suddenly increases in a short time, the terminal device 100 may determine that the light sensor 101b is covered by the auxiliary light guide 204b. That is, the terminal device 100 may determine that the support 202 is in the first position, and the terminal device 100 may control the flash 102 to be turned on.

In another possible case, after the terminal device 100 determines that the amplitude of the electric signal output from the light sensor 101b suddenly decreases, the terminal device 100 may control the flash 102 to emit the first light having the weaker light intensity. Thus, if the light sensor 101b is covered by the auxiliary light guide 204b, the supporting frame 202 will be at the first position, and the first light can be guided to the light sensor 101b through the first light guide 2031a and the auxiliary light guide 204b in sequence, so that the amplitude of the electrical signal output by the light sensor 101b will be increased slightly. If the light sensor 101b is covered by another external object, the amplitude of the electric signal output by the light sensor 101b will not change any more.

In this case, if the terminal device 100 determines that the amplitude of the electric signal output from the light sensor 101b suddenly decreases and then increases with a small amplitude in a short time, the terminal device 100 may determine that the light sensor 101b is covered by the auxiliary light guide 204b. That is, the terminal device 100 may determine that the support 202 is at the first position, and the terminal device 100 may control the flash lamp 102 to be turned on, so that the flash lamp 102 may emit the second light with stronger light intensity.

It should be noted that, the first light emitted by the terminal device 100 to control the flash 102 may be: light that is invisible to the naked eye but that can be sensed by the light sensor 101b ensures that the first light emitted by the flash 102 is not perceived by the user.

It should be further noted that, the light sensor 101b in the terminal device 100 not only can cooperate with the auxiliary light guide 204b to detect the position of the support frame 202, but also can enable the terminal device 100 to sense the intensity of the external ambient light through the light sensor 101b, so that the terminal device 100 can adjust the brightness of the display screen according to the sensed intensity of the ambient light. In addition, when the terminal device 100 is matched with the auxiliary light guide 204b through the light sensor 101b, and the supporting frame 202 is detected to be located at the first position, the light sensed by the light sensor 101b is the light emitted by the flash lamp 102 and is not the external ambient light. For this purpose, the terminal device 100 may turn off the function of adjusting the brightness of the display screen based on the light intensity sensed by the light sensor 101b, and resume the function of adjusting the brightness of the display screen based on the light intensity sensed by the light sensor 101b after the terminal device 100 determines that the support 202 is located at the second position.

In a third alternative implementation manner, as shown in fig. 15 and fig. 16, fig. 15 is a schematic structural diagram of still another support frame provided in an embodiment of the present application, and fig. 16 is a top view of a terminal device mated with the support frame shown in fig. 15. The sensor 101 in the terminal device 100 is a distance sensor 101c. Here, the distance sensor 101c may be generally distributed over the trim component 103. By way of example, the distance sensor 101c typically has an infrared emitting end and an infrared receiving end. The infrared transmitting end in the distance sensor 101c can transmit infrared rays, the infrared rays can be reflected back after encountering an obstacle, the infrared receiving end in the distance sensor 101c can receive infrared rays reflected back by the obstacle in the infrared rays, and then the distance sensor 101c can determine the distance between the infrared transmitting end and the obstacle based on the time of transmitting the infrared rays and the time of receiving the infrared rays.

In this case, the shielding assembly 204 in the protective case 200 may be integrally formed with the support frame 202. That is, the screen assembly 204 may be part of the support frame 202. Again, since the vertical distance between the support frame 202 and the trim component 103 is fixed, and the distance sensors 101c are distributed over the trim component 103. Therefore, when the obstacle covers the distance sensor 101c, if the terminal device 100 detects that the vertical distance between the obstacle and the decoration assembly 103 is within the specified range through the distance sensor 101c, the terminal device 100 may determine that the obstacle covering the distance sensor 101c is the support frame 202, and the terminal device 100 may determine that the support frame 202 is at the first position, and at this time, the terminal device 100 may control the flash 102 to be turned on. If the terminal device 100 detects that the distance sensor 101c is not covered by the obstacle through the distance sensor 101c, or detects that the vertical distance between the obstacle and the decoration assembly 103 is not within the specified range, the terminal device 100 may determine that the support frame 202 is at the second position, and at this time, the terminal device 100 may control the flash 102 to be turned off.

It should be noted that, the distance sensor 101c in the terminal device 100 can not only cooperate with the support frame 202 to detect the position of the support frame 202, but also enable the terminal device 100 to sense the distance between the terminal device and the obstacle through the distance sensor 101c, so that the terminal device 100 can have a function of detecting the distance between the terminal device and the external obstacle.

Optionally, referring to fig. 17 and fig. 18, fig. 17 is a schematic structural view of a supporting frame according to another embodiment of the present application, and fig. 18 is a schematic structural view of a protective housing according to another embodiment of the present application. The support 202 in the protective case 200 may have a retainer E. The protective case body 201 in the protective case 200 has a first stopper F1 and a second stopper F2 that cooperate with the positioning member E. Here, the first limiting member F1 and the second limiting member F2 of the protective housing body 201 are both distributed in an area through which the support frame 202 passes when sliding with respect to the protective housing body 201.

When the supporting frame 202 slides to the first position, the positioning element E in the supporting frame 202 may be cooperatively connected with the first limiting element F1 in the protective housing 201. Thus, through the cooperation connection between the locating piece E and the first limiting piece F1, the supporting frame 202 can be stabilized at the first position of the protective housing body 201, so that the light supplementing component 203 in the protective housing 200 can stably provide light supplementing for the front camera. Similarly, when the support 202 slides to the second position, the positioning element E in the support 202 can be cooperatively connected with the second limiting element F2 in the protective housing 201. In this way, through the cooperation connection between the locating piece E and the first limiting piece F2, the supporting frame 202 can be stabilized at the second position of the protective shell body 201, so as to ensure that the supporting frame 202 in the protective shell 200 cannot slide relative to the protective shell body 201 at will.

It should be noted that, the types of the positioning element E in the supporting frame 202 and the first and second limiting elements F1 and F2 in the protective housing body 201 are various, and the following two cases will be taken as examples in this embodiment of the present application:

in the first case, the positioning element E in the supporting frame 202 may be a first magnet. The first and second stoppers F1 and F2 in the protective housing 201 may be both second magnets. Here, the first magnet can be magnetically connected with the second magnet. For example, when the first magnet is opposite to the second magnet, the magnetic properties of the first magnet toward the second magnet may be opposite to the magnetic properties of the second magnet toward the first magnet.

In the second case, the positioning element E in the supporting frame 202 may be a first buckle. The first limiting member F1 and the second limiting member F2 in the protective housing 201 may be both second buckles. Here, the first buckle can be engaged with the second buckle.

Optionally, first guide rails are disposed on two sides of the supporting frame 202 in the protective case 200, and the protective case body 201 in the protective case 200 has two second guide rails corresponding to the two first guide rails one by one. Here, each first rail may be slidably connected with a corresponding second rail. The support 202 can be stably slid on the protective case body 201 by the mutual cooperation of the two first guide rails and the two second guide rails.

In this application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.
