[0035] The terms "first", "second", and "third" in the embodiments of the present application are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined. All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, then the directional indications will also change accordingly. The terms "include" and "have" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or components inherent to these processes, methods, products, or devices.
[0036] As used herein, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the present application. The phrase may appear in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0037] As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, a device configured to receive / transmit communication signals via a wired connection (such as via a public switched telephone network (PSTN), digital subscriber line (DSL), digital cable, direct cable connection, and / or another data connection / network) and / or via a wireless interface (such as for a cellular network, wireless local area network (WLAN), digital television network such as DVB-H network, satellite network, AM-FM broadcast transmitter, and / or another communication terminal).

A mobile phone is an electronic device configured with a cellular communication module.
[0038] Currently, there is no flying mobile phone terminal accessory (flying mobile phone case) on the market; only drones can be used for aerial photography, but the functions of drones are relatively single for ordinary users. Therefore, not many people specifically purchase drones. Most of the current photography scenarios on the market are in the mode of taking pictures by hand or taking pictures / filming in a fixed mode with a mobile phone.
[0039] In view of this, the embodiments of the present application first provide a protective case for an electronic device. Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of the overall structure of an embodiment of the protective case for the electronic device of the present application, Figure 2 is Figure 1Schematic structural diagram of the deployed state of the protective shell flight assembly in the embodiment; it should be noted that the protective shell in this application can be used in an electronic device and is connected to the electronic device in a cooperative manner. Among them, the electronic device can include electronic devices with a camera assembly such as mobile phones, tablet computers, and wearable devices. The protective shell 100 for the electronic device includes but is not limited to the following structures: a housing 110 and a plurality of flight assemblies 120.
[0040] Specifically, the housing 110 is provided with a connection structure for cooperating with the electronic device. Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of an embodiment of the electronic device system of this application. The electronic device system includes an electronic device 200 and a protective shell 100. The electronic device 200 is detachably connected and cooperated with the protective shell 100, and the two are communicatively controlled and connected.
[0041] Optionally, the housing 110 in this embodiment includes a bottom wall 111 and a side wall 112 of an integral structure. The side wall 112 is disposed along the edge of the bottom wall 111 and encloses to form a receiving space 1100 for receiving the electronic device 200. Among them, the side wall 112 in this embodiment can be one type of the connection structure of the housing 110.
[0042] Among them, there can be multiple flight assemblies 120. Specifically, there can be Figure 1 four in the embodiment, which are arranged at the four corners of the housing 110. In some other embodiments, there can also be other numbers, such as three (please refer to Figure 4 , Figure 4 schematic structural diagram of another embodiment of the protective shell of this application), five, six, or eight. No specific limitation is made here.
[0043] Optionally, each flight assembly 120 includes a connecting rod 121, a driving motor 122, and a rotor 123. One end of the connecting rod 121 is rotatably connected to the housing 110, and the other end is connected to the driving motor 122. The rotor 123 is connected to the driving motor 122 and can rotate under the drive of the driving motor 122; the flight assembly 120 has a folded state ( Figure 1 state in Figure 2 ) and a deployed state ( Figure 2 state in

The size of the flight component 120 in the convenient folding state conforms to the user's usage habits; in the working state, it can be extended through the connecting rod 121, and the two rotor blades can also be simultaneously extended into a symmetrical state to ensure that the rotor provides power for the system in the extended state.
[0045] Please refer to Figure 5 and Figure 6 , Figure 5 is a schematic structural diagram of the folded state of the flight component of this application, Figure 6 is Figure 5 a schematic structural diagram of the extended state of the flight component in the embodiment. The folding rotor is the core part of the protective case and is responsible for generating lift and balance. The folding rotor is the key in the folding and unfolding process. It allows the rotor to fold in the non-working state, and the folded state is the same size as an ordinary mobile phone case to reduce the occupied space, so that the protective case can be used as a normal mobile phone case. When it needs to be unfolded, first, the connecting rod 121 will open from the inside of the housing 110 to the outside.

Please refer to Figure 7 , Figure 7 is the force analysis diagram of the protective case with a quad-rotor structure in this application. Specifically, in combination with mechanical theory:
[0047] 1. When the speeds of the 4 driving motors are increased simultaneously, rising is achieved;
[0048] 2. When the speeds of the 4 driving motors are decreased simultaneously, falling is achieved;
[0049] 3. When the lift generated by the speeds of the 4 driving motors is equal to the gravity of the mobile phone, hovering is achieved;
[0050] 4. On the basis of hovering, maintaining the speeds of M1 / M3 unchanged and increasing the speeds of M2 / M4, rotation to the right is achieved, and yaw to the right is achieved.
[0051] 5. Increasing the speeds of M1 / M4 simultaneously or decreasing the speeds of M2 / M3, generating a resultant force in the upper right direction, and combining with the gravity factor to make it move to the right.
