Description

This application claims priority to Chinese Patent Application No. 202111680070.2, filed with the China National Intellectual Property Administration on December 31, 2021 and entitled "OPEN BUTTON AND ELECTRONIC DEVICE". TECHNICAL FIELD This application relates to the field of electronic devices, and in particular, to an open button and an electronic device. BACKGROUND An electronic device that can be opened and closed usually has an open button, and the open button is configured to latch and unlatch two parts of the electronic device. When the two parts are closed, the open button can latch the two parts to latch the electronic device. When a user presses the open button, the two parts can be unlatched, so that the electronic device can be opened. A conventional open button cannot provide a touch feeling feedback for the user, and cannot meet a user requirement, and consequently user experience is poor. CN 110417089 A discloses a wireless headset charging box with clamping parts and magnetic absorption members. CN 209045415 U discloses a utility model describing a film key capable of improving pressing hand feeling. SUMMARY The present invention is defined by the features disclosed in the independent claims. Additional embodiments are defined in the dependent claims. Embodiments of this application provide an open button and an electronic device, so that a touch feeling feedback is provided for a user when the user performs pressing, thereby meeting a user requirement and improving user experience. According to a first aspect, an embodiment of this application provides an open button of an electronic device, in accordance with claim 1. The electronic device includes a first part and a second part that can be opened and closed, one of the first part and the second part is a cover of the electronic device, and the other is a body of the electronic device. The open button is configured to be mounted to the second part, and the open button includes a cap, an elastic member, and a touch-sensitive spring. The cap is configured to form a detachable connection with the first part, and the cap has a bump. The touch-sensitive spring and the bump are disposed at a spacing, and the touch-sensitive spring can generate elastic deformation when being squeezed. The cap can move towards the touch-sensitive spring when being pressed, so that the detachable connection is released, and the bump of the cap squeezes the touch-sensitive spring. The elastic member presses against the cap, and is configured to provide a rebound force for the cap when the cap moves towards the touch-sensitive spring. In this solution, the open button can implement latching and unlatching of the electronic device. In addition, the touch-sensitive spring is designed, so that a user can experience a touch feeling feedback when pressing the cap. In this way, a user requirement can be met, and user experience can be improved. In an implementation of the first aspect, the cap has a buckle, the buckle is disposed opposite to the bump at a spacing, and the buckle is configured to form a detachable buckle connection with a latch portion on the second part; the touch-sensitive spring is located between the bump and the buckle, and the touch-sensitive spring and the buckle are disposed at a spacing; and the cap can move towards the touch-sensitive spring when being pressed, so that the buckle is separated from the latch portion, and the buckle connection is released. In this solution, latching and unlatching functions of the open button can be implemented by using a simple and reliable structure. In an implementation of the first aspect, the cap includes a pressing portion and a bearing portion, two ends of the bearing portion each are connected to the pressing portion, and the bearing portion and the pressing portion enclose an open space; the bump of the cap is located on a side that is of the pressing portion and that faces the open space, and the buckle is located on the bearing portion; the touch-sensitive spring is located in the open space; and when the pressing portion is pressed, the pressing portion can drive the bearing portion to move towards the touch-sensitive spring. In this solution, latching and unlatching functions of the open button can be implemented by using a simple and reliable structure. The open button in this solution has a reliable structure and stable performance, and is easy for mass production. In an implementation of the first aspect, the open button includes a button support, a part of the button support is located in the open space, and the other part of the button support is located outside the open space and is slidably connected to the bearing portion; the touch-sensitive spring is fastened on the button support; and when the pressing portion is pressed, the pressing portion can drive the bearing portion to slide relative to the button support. In this solution, the button support can guide the cap, so that the cap can move
