For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] First see Figure 1The utility model provides a foldable mobile phone case 10, which is used to be mounted on a foldable mobile phone to protect the foldable mobile phone from wear and tear. It can be understood that the foldable mobile phone case 10 can also be mounted on electronic devices such as foldable tablets. Specifically, the foldable mobile phone case 10 includes a shell 100, a central axis protection cover 200 and a magnet 300. The shell 100 is provided with a mounting cavity 110, and the mounting cavity 110 is used to mount the foldable mobile phone. The central axis protection cover 200 is detachably arranged on the edge of the shell 100. The central axis protection cover 200 is rotatably connected to the edge of the shell 100 through a rotating shaft 210. The central axis protection cover 200 can be flipped relative to the shell 100 around the rotating shaft 210 to be attached to the central axis of the foldable mobile phone. The magnet 300 is fixedly arranged on the central axis protection cover 2 00, the magnet 300 can magnetically attract the foldable mobile phone through magnetic attraction, so that when the foldable mobile phone is unfolded or folded, the central axis protection cover 200 rotates relative to the shell 100 and is always attached to the central axis of the foldable mobile phone through magnetic attraction. The central axis protection cover 200 and the shell 100 rotate through the rotating shaft 210, which avoids the connection from being broken due to long-term folding, and the central axis protection cover 200 and the shell 100 are detachably connected, which is convenient for users to replace different styles of central axis protection covers 200 to meet different usage needs of users.

[0035] refer to Figure 1 The rotating shaft 210 is arranged on the central axis protection cover 200 and is integrally connected with the central axis protection cover 200. A notch 120 is arranged on the edge of the shell 100 close to the central axis protection cover 200. The rotating shaft 210 is arranged in the notch 120 and can rotate relative to the shell 100 in the notch 120. The notch 120 penetrates the shell 100 along the thickness direction of the shell 100, so that when the rotating shaft 210 rotates, the notch 120 can avoid the rotating shaft 210. It should be noted that the rotating shaft 210 can also be arranged on the edge of the shell 100, and the notch 120 is correspondingly arranged on the central axis protection cover 200. The notch 120 20 may also not penetrate the shell 100. For example, the notch 120 is set to be closed on the side close to the inner surface of the shell 100, and the notch 120 is set to be open on the side close to the outer surface of the shell 100. When the rotating shaft 210 rotates, the opening of the notch 120 on the side close to the outer surface of the shell 100 can avoid the rotating shaft 210. It can be understood that the notch 120 may also not be set. For example, the edge of the shell 100 extends outward to form two clamping columns that can connect the rotating shaft 210, and the rotating shaft 210 is rotatably set between the two clamping columns, thereby realizing the rotational connection between the central axis protection cover 200 and the shell 100.

[0036] refer to Figure 1, connecting grooves 211 are provided at the two opposite ends of the rotating shaft 210, and a connecting column 121 is provided on the inner wall of the notch 120. The connecting column 121 matches the connecting groove 211, so that the connecting column 121 can be inserted into the connecting groove 211 and rotate in the connecting groove 211. The connecting column 121 can be inserted into or disengaged from the connecting groove 211 through extrusion deformation under the action of external force, so that the central axis protection cover 200 can be disassembled relative to the shell 100. It should be noted that the connecting groove 211 can also be set on the inner wall of the notch 120, and the connecting column 121 can also be set at the opposite ends of the rotating shaft 210.

[0037] The end portion of the connecting column 121 that can be inserted into the connecting groove 211 includes an end face 1211 and a side face 1212. The end face 1211 is perpendicular to the axis of the connecting column 121. The end face 1211 is connected to the side face 1212. The side face 1212 is connected end to end along the axis of the connecting column 121. That is, the side face 1212 is an annular surface structure. In the process of extending along the axial direction of the connecting column 121 and toward the end where the end face 1211 is located, the radial dimension of the side face 1212 gradually decreases, and the radial dimension of the side face 1212 is greater than the radial dimension of the end face 1211. When the central axis protection cover 200 is removed, the central axis protection cover 200 and the housing 100 are respectively subjected to opposite external forces, so that the connecting column 121 squeezes the connecting groove 211. The groove wall, the connecting column 121 is deformed, the side surface 1212 abuts against the edge of the connecting groove 211 and slides relatively, so that the connecting column 121 is separated from the connecting groove 211 along the side surface 1212. When the central axis protection cover 200 is installed, the connecting column 121 abuts against the edge of the rotating shaft 210. Under the push of external force, the connecting column 121 is deformed, so that the side surface 1212 abuts against the edge of the rotating shaft 210 and slides relatively, so that the connecting column 121 enters the connecting groove 211 along the side surface 1212, and the connecting column 121 recovers its deformation in the connecting groove 211. It can be understood that the connecting column 121 and the rotating shaft 210 are made of plastic or other materials, so that the connecting column 121 has deformation performance while ensuring hardness.

[0038] The notch of the connecting groove 211 is provided with a connecting surface 2111, which is connected to the inner peripheral wall of the connecting groove 211, and the connecting surface 2111 is closed along the axial circumferential direction of the connecting groove 211. The connecting surface 2111 has the inner peripheral wall of the connecting groove 211 extending obliquely to the side away from the bottom wall of the connecting groove 211. In the process of extending along the axial direction of the connecting groove 211 and in the direction away from the bottom wall of the connecting groove 211, the radial dimension of the connecting surface 2111 gradually increases, and the radial dimension of the connecting surface 2111 is greater than the radial dimension of the inner peripheral wall of the connecting groove 211. When the central shaft protection cover 200 is removed, the connecting column 121 is squeezed and deformed, so that the side surface 1212 abuts against the connecting surface 2111, and when an external force is applied When in use, the side surface 1212 and the connecting surface 2111 slide relative to each other, so that the connecting column 121 is separated from the connecting groove 211, and the central axis protection cover 200 is separated from the shell 100, so that the user can replace different styles of central axis protection covers 200 when in use. When installing the central axis protection cover 200, the connecting column 121 abuts against the edge of the rotating shaft 210. Under the action of external force, the connecting column 121 is deformed so that the connecting column 121 slides over the edge of the rotating shaft 210 along the side surface 1212. When the connecting column 121 enters the connecting groove 211, the side surface 1212 abuts against the connecting surface 2111 and slides relative to each other, so that the connecting column 121 slides into the connecting groove 211 along the connecting surface 2111 to complete the installation of the central axis protection cover 200.

[0039] The connecting column 121 is arranged at one end of the inner wall of the notch 120 close to the outer surface of the shell 100, that is, the connecting column 121 is arranged on the side of the inner wall of the notch 120 deviating from its center. When the rotating shaft 210 is installed in the notch 120, the distance from the connecting column 121 to the edge of the rotating shaft 210 is smaller than the distance from the connecting column 121 to the inner surface of the shell 100, so that when the rotating shaft 210 rotates in the notch 120, the side wall of the rotating shaft 210 does not protrude from the inner surface of the shell 100. The inner surface of the shell 100 is the surface to which the shell 100 and the folding mobile phone are attached, and the outer surface of the shell 100 is the surface facing away from the inner surface of the shell 100, so that the rotating shaft 210 will not wear the folding mobile phone when it rotates.

[0040] The central axis protection cover 200 can rotate relative to the shell 100, and the rotation angle of the central axis protection cover 200 is at least 90 degrees. When the folding mobile phone is in a folded state, the edges at both ends of the central axis protection cover 200 abut against the shell 100, and the central axis protection cover 200 is attached to the central axis of the folding mobile phone. At this time, the thickness direction of the central axis protection cover 200 is perpendicular to the thickness direction of the shell 100. When the folding mobile phone is folded, the two folding parts of the folding mobile phone gradually unfold, and the central axis protection cover 200 rotates relative to the shell 100 around the rotation axis 210 under the push of the folding mobile phone. During the rotation process, the central axis protection cover 200 is always attached to the central axis of the folding mobile phone. When the folding mobile phone is fully unfolded, the central axis protection cover 200 rotates until the thickness direction is parallel to the thickness direction of the shell 100, and the rotation angle of the central axis protection cover 200 is 90 degrees. It can be understood that when the rotation angle of the folding mobile phone can exceed 180 degrees, the rotation angle of the central axis protection cover 200 relative to the shell 100 can also be greater than 90 degrees.

[0041] There are two rotating shafts 210, and the two rotating shafts 210 are arranged at intervals at the connection between the middle axis protection cover 200 and the edge of the shell 100. The corresponding edge of the shell 100 is provided with two notches 120, and the two notches 120 are also arranged at intervals. The two rotating shafts 210 can be rotatably connected to the shell 100 in the two notches 120 respectively, so that the middle axis protection cover 200 is more stable when rotating relative to the shell 100. It can be understood that there can also be multiple rotating shafts 210 and notches 120, and multiple rotating shafts 210 and notches 120 are arranged at intervals, so that the connection between the middle axis protection cover 200 and the shell 100 is more secure. There can also be one rotating shaft 210 and one notch 120, and one rotating shaft 210 and one notch 120 are respectively arranged at the middle position of the connection between the middle axis protection cover 200 and the shell 100.

[0042] refer to Figure 1The central axis protection cover 200 is provided with a fixing groove 220, and the fixing groove 220 is provided on the inner side of the central axis protection cover 200. The magnet 300 is fixed in the fixing groove 220. When the magnet 300 is fixed in the fixing groove 220, the magnet 300 does not exceed the notch of the fixing groove 220, so that the inner side surface of the central axis protection cover 200 remains flush. A plurality of fixing grooves 220 are provided, and a plurality of fixing grooves 220 are arranged at intervals along the inner side surface of the central axis protection cover 200. A plurality of magnets 300 are also provided, and a plurality of magnets 300 are respectively fixed in the fixing grooves 220. The plurality of magnets 300 can absorb the folding mobile phone through magnetic attraction, so that the central axis protection cover 200 is always attached to the folding mobile phone when rotating. Mobile phone, the magnet 300 is divided into multiple and respectively fixed in the fixing groove 220, so that the single magnet 300 is more secure when fixedly connected to the central axis protection cover 200, and saves materials. Each magnet 300 faces the inner side of the central axis protection cover 200, that is, each magnet 300 has the same magnetic properties on the same side. It can be understood that in other embodiments, one fixing groove 220 can also be set, and the fixing groove 220 extends from one end to the other end along the long side extension direction of the central axis protection cover 200. A magnet 300 can also be set accordingly, so that the magnet 300 is fixed in the fixing groove 220. In addition, the magnet 300 can also be built inside the cover body of the central axis protection cover 200.

[0043] A protective pad 230 is also provided on the inner side of the central axis protection cover 200, and the protective pad 230 covers the notch of the fixing groove 220 to make the inner side of the central axis protection cover 200 flush. When the central axis protection cover 200 is attached to the central axis of the folding mobile phone, the protective pad 230 is located between the magnet 300 and the folding mobile phone, and the protective pad 230 contacts the folding mobile phone to prevent the central axis protection cover 200 from wearing the folding mobile phone when the central axis protection cover 200 is folded and rotated with the folding mobile phone. In this embodiment, the protective pad 230 is provided at one end of the central axis protection cover 200 and extends to the other end, so that the central axis of the folding mobile phone is completely attached to the protective pad 230. It can be understood that the protective pad 230 can also be provided in sections, that is, the protective pad 230 is divided into multiple sections, and the multiple protective pads 230 respectively cover the notches of multiple fixing grooves 220. The material of the protective pad 230 is a soft material to prevent the folding mobile phone from being worn.

[0044] refer to Figure 1A support plate 130 is provided on the side of the housing 100 facing away from the installation cavity 110. The support plate 130 is rotatably connected to the housing 100 so that an angle is formed between the support plate 130 and the housing 100 and the housing 100 is tilted to support the support plate 130, so that the support plate 130 is used to diagonally support the foldable mobile phone for convenience of use by users. A storage groove 140 is also provided on the side of the housing 100 facing away from the installation cavity 110. The storage groove 140 can accommodate the support plate 130, and the storage groove 140 can provide a rotation space for the end portion of the support plate 130 connected to the housing 100. When the support plate 130 is in a state of being folded, the housing 100 is folded and the housing 100 is folded. When the plate 130 is opened and forms an angle with the shell 100, the support plate 130 abuts against the external support surface, so that the shell 100 is in an inclined upright state. When the support plate 130 is closed and attached to the outer surface of the shell 100, the support plate 130 is accommodated in the storage groove 140 to prevent the support plate 130 from being damaged. In addition, the support plate 130 is hinged to the shell 100, and a damper is provided at the connection between the support plate 130 and the shell 100 to prevent the support plate 130 from rotating relative to the shell 100 when there is no external force.

[0045] The shell 100 is provided with a plurality of channels 150 in the direction from the inner surface to the outer surface. The channels 150 penetrate the shell 100 and are used for heat dissipation of the folding mobile phone to prevent the folding mobile phone from having an excessively high temperature after being mounted with the shell 100 and affecting user use.
