Although such a solution makes the protective shell light and thin, there is no gap between the shaft cover protective structure and the shaft cover. It has a very good buffering effect, so the protective shell cannot effectively protect the shaft cover. After a collision, the shaft cover and hinge device are easily damaged.

Embodiments of the present application provide a protective case that can improve the above technical problems.

Please refer to Figures 1, 2, 3, and 4. The protective case in the embodiment of the present application is used to protect the foldable electronic device.

The bottom case protection part 200 is used to cover the back of the rear body; the shaft cover protection part 300 is reversibly installed on the side of the bottom case. The shaft cover protection part 300 is used to cover the shaft cover. 104; a recess is provided on the inner side of the shaft cover protection part 300. The position of the recess is relative to the position of the designated protection area of the hinge device, and a buffer gap is formed between the recess and the designated protection area. The bottom case protection part 200 and the shaft cover protection part 300 can effectively protect the rear body and the shaft cover 104 of the foldable electronic device, prevent the rear body and the shaft cover 104 from being scratched, bumped or contaminated, and extend the use of the foldable electronic device. life. At the same time, the protective case of the embodiment of the present application does not require a top case covering the front body 100, so it does not increase the weight and thickness of the foldable electronic device, improves the durability and portability of the foldable electronic device, and eliminates the need for a front case. This avoids the problem of insensitive screen gesture operations. The protective case of the embodiment of the present application solves the technical problem that the protective case without a front case has weak protection ability for the shaft cover 104 area of the foldable electronic device.

It should be noted that the protective cases mentioned in the embodiments of the present application are mainly used for foldable electronic devices, especially foldable screen mobile phones.

The foldable electronic device includes a front body 100, a rear body, a hinge device disposed between the front body 100 and the rear body, and a shaft cover 104 located outside the hinge device. The hinge device includes a main swing arm, a auxiliary swing arm and other structures.

It should be noted that the designated protection area of the hinge device can refer to the structural strength of the hinge device and the area where components with weak connection strength are located, that is, the area that is prone to damage after a collision. Furthermore, the designated protection area also It can be the area where key components of the hinge device are located. Damage to these key components affects whether the entire hinge device can work normally. Designated protection areas such as the area where the main swing arm is located, the area where the auxiliary swing arm is located, etc.

It should be noted that the connection method between the bottom case protection part 200 and the rear body can be snap-in connection, that is, a snap-in chamber is provided inside the bottom case protection part 200, and the rear body is snapped into the snap-in chamber for connection. Of course, the bottom shell The connection method between the protective part 200 and the rear body can also be glued, magnetically connected, etc., but is not limited to this.

It should be noted that the inner side of the shaft cover protection part 300 mentioned in the embodiment of the present application is the side of the shaft cover protection part 300 facing the direction of the shaft cover 104 after the protective shell is installed on the foldable electronic device. The back side of the protection part 300 is opposite to the inside of the shaft cover protection part 300. The inside of the bottom case protection part 200 is the side where the bottom case protection part 200 faces the direction of the rear body after the protective case is installed on the foldable electronic device. The back side of the case protection part 200 is opposite to the inner side of the bottom case protection part 200 . It should be noted that the parts of the hinge device contain ferrous structures.

Among them, the protective shell in the embodiment of the present application forms a buffer gap between the recess and the designated protection area of the hinge device, which can form a certain gap between the shaft cover protection part 300 and the hinge device, reducing the distance between the shaft cover protection part 300 and the hinge device. The friction and impact between the shaft covers 104 can thereby reduce the impact on the designated protection area of the hinge device, prevent damage to key components of the hinge device, ensure the normal opening and closing of the foldable electronic device, and improve the protection of the protective shell without a front shell against the shaft. Cover the buffering capacity of the 104 area. At the same time, the protective shell in the embodiment of the present application can provide a certain relative displacement space between the shaft cover protection part 300 and the hinge device by setting a buffer gap between the recess and the designated protection area, thereby preventing the shaft cover protection part 300 from affecting the hinge. The device causes excessive pressure or tension, affecting the movement performance of the hinge device.

The protective shell in the embodiment of the present application is reversibly installed on the side of the bottom shell by providing the shaft cover protection part 300. The shaft cover protection part 300 can be easily removed or installed from the shaft cover 104, which facilitates user replacement or cleaning protection. shell. At the same time, the protective shell of the embodiment of the present application is reversibly installed on the side of the bottom shell by providing the shaft cover protection part 300, so that the shaft cover protection part 300 can be flipped outward when not needed, which facilitates cleaning of the shaft cover 104 and the shaft. The gap between the cover 104 and the front body 100, and the gap between the axle cover 104 and the rear body.

Please refer to Figure 4. Since the structure of the hinge device is relatively precise and complex, in order to protect components with weak structural strength, connection strength, and key components, the designated protection areas and recesses in the embodiment of the present application are both There are a plurality of recesses, and the positions of the plurality of recesses respectively correspond to the positions of a plurality of designated protection areas. The protective case of the embodiment of the present application can form multiple gaps between the axle cover protection part 300 and the hinge device by arranging multiple recesses and multiple designated protection areas to form multiple gaps, thereby dispersing the axle cover protection part 300 and the hinge device. The friction and impact between them ensure the normal opening and closing of foldable electronic devices. At the same time, the protective case of the embodiment of the present application forms a buffer gap between multiple recesses and multiple designated protection areas, so that there are multiple relative displacement spaces between the protective case and the hinge device, thereby preventing the protective case from causing excessive damage to the hinge device. Large pressure or tension affects the movement performance of the hinge device. By arranging multiple recesses and multiple designated protection areas to form buffer gaps, the buffering effect of the shaft cover protection part 300 on the hinge device at different positions can be made more balanced and coordinated, and the situation of insufficient or excessive buffering at certain positions can be avoided. , which improves the adaptability of the protective shell without front shell to the shaft cover 104 area. Multiple designated protection areas include but are not limited to the area where the main swing arm is located and the area where the auxiliary swing arm is located.

Please refer to Figure 4 to better protect the weak points of the hinge device and achieve a better protection effect. In the embodiment of the present application, the plurality of designated protection areas include a first designated protection area 105 and a second designated protection area 106, and the plurality of recessed portions include a first recessed portion 301 and a second recessed portion 302. The position of the first recessed portion 301 is related to that of the second recessed portion 302. A designated protection area 105 is positioned relative to the position of the second recess 302 and the second designated protection area 106 is positioned opposite; wherein, the structural strength of the first designated protection area 105 is greater than the structural strength of the second designated protection area 106, The minimum depth in the first recess 301 is smaller than the depth at any position in the second recess 302 .

Please refer to FIG. 4 . It should be noted that the minimum depth in the first recess 301 is less than the depth of any position in the second recess 302 , so that the distance between the bottom of the first recess 301 and the first designated protection area 105 is less than The distance between the bottom of the second recess 302 and the second designated protection area 106. When a collision occurs, since the minimum depth in the first recess 301 is less than the depth of any position in the second recess 302, the shaft cover protection part 300 will contact first. to the area of the shaft cover 104 corresponding to the first designated protection area 105, and then the collision force will be transmitted to the parts in the first designated protection area 105 with greater structural strength, and part of it will be absorbed by the structure in this area. After that, the collision force will be transmitted to the parts in the second designated protection area 106 with a smaller structural strength, thereby effectively protecting the parts in the second designated protection area 106 with a smaller structural strength and preventing the components in the second designated protection area 106 from being damaged. parts are damaged to ensure the normal operation of the hinge device.

Please refer to FIG. 4 . In a specific embodiment, the parts in the first designated protection area 105 include the main swing arm, the parts in the second designated protection area 106 include the auxiliary swing arm, and the bottom of the first recess 301 The distance from the main swing arm is A, and the distance between the bottom of the second recess 302 and the auxiliary swing arm is A+S. It can be seen that when a collision occurs, since A<A+S, the axle cover protection part 300 first contacts the area of the axle cover 104 corresponding to the main swing arm, and the received collision force will first be transmitted to the main swing arm and be absorbed by the area. The structure absorbs part of it. After that, the collision force received by the shaft cover protection part 300 will be transmitted to the auxiliary swing arm, thereby effectively protecting the auxiliary swing arm with a smaller structural strength, preventing damage to the auxiliary swing arm parts, and ensuring the normal operation of the hinge device.

It should be noted that recesses of different depths can be set according to the structural strength of different designated protection areas to achieve the best match between different designated protection areas and different recesses and improve the buffering effect between the protective shell and the hinge device. The protective case in the embodiment of the present application can provide the first designated protection area 105 and the second designated protection area 106, as well as the first recess 301 and the second recess 302 corresponding thereto, so that the protective case can protect the hinge device at different positions. The buffering effect is more reasonable and balanced, avoiding the situation where the buffering is too large or too small in certain positions, and improving the adaptability of the protective shell without a front shell to the shaft cover 104 area.

In the embodiment of the present application, the bottom end surface of the first recessed portion 301 and/or the bottom end surface of the second recessed portion 302 is arranged smoothly. By arranging the bottom end surfaces of the first recess 301 and the second recess 302 smoothly in the protective case of the embodiment of the present application, the buffering effect between the protective case and the hinge device can be made softer and smoother, and the occurrence of a gap between the protective case and the hinge device can be avoided. Sharp or protruding contact may cause damage to the hinge device or deformation of the protective shell. At the same time, by setting the bottom end surfaces of the first recess 301 and the second recess 302 smoothly in the protective shell of the embodiment of the present application, the shaft cover protection part 300 can evenly disperse and transmit the external force when it is acted upon by external force, thereby avoiding the occurrence of protection. Improve the structural strength of the protective shell when the force on the shell is too large or too small at certain locations. In one embodiment, the bottom end surface of the first recessed portion 301 and the bottom end surface of the second recessed portion 302 are both smoothly arranged to effectively prevent damage caused by stress concentration.

In order to further ensure the structural strength of the shaft cover protection part 300 and prevent structural problems such as stress concentration, the plurality of recesses in the embodiment of the present application include at least one set of adjacent first recesses 301 and second recesses 302. The bottom end surface of the first recessed portion 301 and the bottom end surface of the second recessed portion 302 are smoothly transitioned. The protective case of the embodiment of the present application is configured by arranging at least one set of adjacent first recesses 301 and second recesses 302, and forming an arc or bevel shape between the adjacent first recesses 301 and second recesses 302. The transition structure can avoid the problem of structural damage caused by excessive stress concentration.

The first side of the axle cover protection part 300 in the embodiment of the present application is reversibly installed on the side of the bottom case, and the second side of the axle cover protection part 300 is used to abut against the front body 100 . When a collision occurs, in the early stage of the collision, because the second side of the axle cover protection part 300 is in contact with the front body 100, the front body 100 absorbs part of the impact force. Later, because the minimum depth in the first recess 301 is smaller than the second recess At any depth within 302, the shaft cover protection part 300 will first contact the area of the shaft cover 104 corresponding to the first designated protection area 105, and then the collision force will be transmitted to the parts in the first designated protection area 105 with greater structural strength. , and is partially absorbed by the structures in the area. After that, the collision force will be transmitted to the parts in the second designated protection area 106 with a smaller structural strength, thereby effectively protecting the parts in the second designated protection area 106 with a smaller structural strength and preventing the components in the second designated protection area 106 from being damaged. parts are damaged to ensure the normal operation of the hinge device.

It should be noted that the front body 100 in the embodiment of the present application includes a middle frame 101 and a front screen assembly 102 installed on the middle frame 101. The second side of the shaft cover protection part 300 abuts against the middle frame 101 of the front body 100. superior. Since the middle frame 101 is much stronger than the front screen component 102, the front screen component 102 can be protected from damage.

Since the foldable electronic device has the front body 100 and the rear body in an unfolded state at a certain angle, and the front body 100 and the rear body in a folded state, in the folded state, the shaft cover protection part 300 abuts against the side of the front body 100 or on the middle frame 101, but after the device is unfolded, the shaft cover protection part 300 will reach the front side of the front body 100, causing wear and tear on the screen. When the protective film 103 is attached to the screen, the shaft cover protection part 300 will move forward. During the movement of the front side of the body 100, the edge of the protective film 103 will also be scraped. To this end, please refer to Figures 1, 2, 3, 5, 6, and 7.
