Description

CROSS-REFERENCE TO RELATED APPLICATIONS This is a continuation of International Patent Application No. PCT/CN2024/097970, filed on Jun. 7, 2024, which claims priority to Chinese Patent Application No. 202311438629.X, filed on Oct. 31, 2023, which are both incorporated by reference. TECHNICAL FIELD This disclosure relates to the field of electronic devices, and in particular, to an electronic device. BACKGROUND An electronic device includes components such as a housing, a battery, a screen, and a camera. The housing includes a rear cover and a middle frame, and the screen is mounted on the housing. The rear cover, the middle frame, and the screen enclose a battery compartment for accommodating the battery. In some instances, devices such as a camera and a flash are mounted on the rear cover of the electronic device via a camera decoration member. The camera decoration member and the battery compartment are arranged in a length direction of the electronic device. When a length of the camera decoration member is increased, a length of the battery compartment is reduced. Consequently, a capacity of the battery is reduced, which is not conducive to improvement of a battery life. SUMMARY This disclosure provides an electronic device, which can improve reliability of an entire system while a length of a camera decoration member and a capacity of a battery are increased. Embodiments of this disclosure provide an electronic device. The electronic device includes a housing, where the housing includes a middle frame and a rear cover assembly, the rear cover assembly includes a rear cover and a camera decoration member mounted on the rear cover, and the middle frame is connected to the rear cover; a functional device and a camera that are mounted on the camera decoration member; and a battery and a mainboard. The housing has a first accommodating cavity configured to accommodate the mainboard and a second accommodating cavity configured to accommodate the battery. The camera decoration member includes a first mounting portion configured to mount the camera and a second mounting portion configured to mount the functional device, and the second mounting portion extends to above the second accommodating cavity. The middle frame includes a barrier wall. The barrier wall is located between the first accommodating cavity and the second accommodating cavity, and the barrier wall supports the rear cover assembly. In this embodiment of this disclosure, in the camera decoration member of the rear cover assembly, the second mounting portion configured to mount the functional device extends to above the second accommodating cavity in a length direction of the electronic device, so that a projection of the second mounting portion in a thickness direction of the electronic device covers a part of the second accommodating cavity configured to accommodate the battery. In this way, a length of the camera decoration member is increased, and a length of the second accommodating cavity configured to accommodate the battery is not reduced in this manner, which helps increase a capacity of the battery. The barrier wall of the middle frame extends in the thickness direction of the electronic device to support the rear cover assembly, which reduces a risk that the rear cover assembly and components (for example, a primary camera and the functional device) mounted on the rear cover assembly move toward the inside of the accommodating cavity or deform. This reduces a risk of damaging the component in the accommodating cavity. Especially, this can reduce a risk that the second mounting portion and the functional device mounted on the second mounting portion move toward the second accommodating cavity or deform. In this way, a risk of damaging the battery in the second accommodating cavity is reduced, and reliability of an entire system is improved. In an embodiment, the barrier wall is bonded to the rear cover assembly. This further improves reliability that the barrier wall supports the rear cover assembly, and further reduces a risk that the rear cover assembly and the functional device mounted on the rear cover assembly move toward the battery under an action of an external force. In addition, an adhesive material that bonds the rear cover assembly and the barrier wall can further buffer an impact force between the barrier wall and the rear cover assembly. In an embodiment, the barrier wall has a first end face supporting the rear cover assembly. A size of the first end face in the length direction of the electronic device is L1, and 0.5 millimeters (mm)≤L1 ≤1.5 mm. In this embodiment, a contact area between the barrier wall and the rear cover assembly is moderate, so that reliability that the barrier wall supports the rear cover assembly is good, and a length of the first accommodating cavity and the length of the second accommodating cavity are not significantly reduced. In an embodiment, the barrier wall has a second end face disposed oppo
