[0032] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Furthermore, in order to provide a clearer description and make it easier to understand the present application, the parts in the drawings are not drawn according to their relative sizes, and some sizes have been exaggerated compared to other related scales; irrelevant details are not fully drawn to simplify the drawings.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment provides a pen cover, which includes a wrapping portion 1 and a storage portion 2. The wrapping portion 1 is a cylindrical structure with a closed top, and is used to cover the tip of the electronic pen 4. The tip of the electronic pen 4 can be inserted from the bottom of the wrapping portion 1 into the inside of the wrapping portion 1. The storage portion 2 is fixed to the side of the wrapping portion 1, and is used to store a Bluetooth adapter 5. The inside of the storage portion 2 is hollow, and the top of the storage portion 2 is open. The Bluetooth adapter 5 can be inserted from the top of the storage portion 2 into the inside of the storage portion 2, as shown in FIG. Figure 2 shown.

[0035] Specifically, in this embodiment, the pen cover as a whole can be divided into a wrapping part 1 and a storage part 2. The wrapping part 1 is a cylindrical structure with a closed top. The inner cavity shape of the wrapping part 1 can be designed accordingly according to the shape of the pen tip of the electronic pen 4, and it is necessary to try to ensure that there is a certain friction between the inner cavity of the wrapping part 1 and the part where the pen tip contacts, so as to prevent the pen cover from falling off. It is also possible to process an external thread on the pen body of the electronic pen 4, and process an internal thread on the inner wall of the wrapping part 1, so that the wrapping part 1 can be connected to the electronic pen 4 through the thread. At the same time, since the pen tip of the common electronic pen 4 is mostly a cone structure, in the case of this structure, the stability between the inner cavity of the wrapping part 1 and the pen tip is poor. Therefore, in this embodiment, the length of the pen cover can be increased so that the pen cover contacts the pen body to ensure the stability of the pen cover on the electronic pen 4. A buffer layer can also be provided on the inner wall of the wrapping part 1. The material of the buffer layer can be soft materials such as rubber and sponge to further protect the pen tip of the electronic pen 4.

[0036] A storage portion 2 is provided on the side of the wrapping portion 1. The top of the storage portion 2 is open and the interior is hollow, and is used to store the Bluetooth adapter 5. The Bluetooth adapter 5 can be inserted into the inner cavity of the storage portion 2 from the top of the storage portion 2, such as Figure 2As shown. The inner cavity of the storage part 2 can be designed according to the overall shape of the Bluetooth adapter 5. There is also a certain friction between the inner cavity of the storage part 2 and the outer surface of the Bluetooth adapter 5. The Bluetooth adapter 5 can be plugged into an external device, so that the electronic pen 4 can be paired with the external device through the Bluetooth adapter 5, and then the user can use the electronic pen 4 to perform related operations on the external device. In this embodiment, the storage between the Bluetooth adapter 5 and the storage part 2 can also be achieved by magnetic attraction or snap-on methods.

[0037] In this embodiment, the pen cap can effectively protect the tip of the electronic pen 4 to prevent the tip from being damaged by contact with external hard objects. At the same time, the electronic pen 4 and the Bluetooth adapter 5 can be integrated together, which is convenient for users to carry and use at the same time.

[0038] Furthermore, the pen cover described in this embodiment also includes a charging unit 3. The charging unit 3 is arranged below the storage unit 2 and as close to the pen body of the electronic pen 4 as possible. The charging unit 3 has a built-in wireless charging circuit 6. A charging port is provided on the charging unit 3, and a charging interface 7 is provided in the charging port. Figure 2 As shown. The charging interface 7 can be connected to an external power source and electrically connected to the wireless charging circuit 6 at the same time, so that the electric energy output by the external power source is transmitted to the wireless charging circuit 6 through the charging interface 7, and then the wireless charging circuit 6 wirelessly charges the battery inside the electronic pen 4. In order to enable the wireless charging circuit 6 to wirelessly charge the battery inside the electronic pen 4, several prerequisites need to be met. First, the battery inside the electronic pen 4 must be a battery that can be wirelessly charged. Second, the wireless charging circuit 6 should be as close to the battery as possible to ensure the stability and effectiveness of charging.

[0039] In addition, in this embodiment, the charging part 3 is a long strip structure as a whole, and the part where the charging part 3 contacts the storage part 2 is set to a bendable structure. For example, a softer material can be used as a connector between the charging part 3 and the storage part 2, or the charging part 3 and the storage part 2 can be connected in a hinged manner. In this way, the charging part 3 as a whole can also be used as a "pen clip", which is convenient for users to clip the electronic pen on clothes or pockets through the charging part 3.

[0040] Of course, in this embodiment, the position of the charging portion 3 is not limited to the above position, and can also be determined according to the overall appearance design of the electronic pen 4 and the location of the battery inside the electronic pen 4. In addition, the position of the charging port 7 electrically connected to the wireless charging circuit 6 can also be set at other positions, such as on the wrapping portion 1 or the storage portion 2. Figure 3 As shown, it is sufficient to ensure that there is a reliable electrical connection between the wireless charging circuit 6 and the charging interface 7.

[0041] Furthermore, if Figure 5As shown, the Bluetooth adapter 5 proposed in this embodiment includes an interface terminal 5-1 and a handheld terminal 5-2. The interface terminal 5-1 can be used to connect to an external device. The handheld terminal 5-2 can be inserted into the interior of the storage portion 2 from the top of the storage portion 2. The handheld terminal 5-2 is built with a circuit structure that can realize circuit connection and signal transmission with the interface terminal 5-1, so that the electronic pen 4 can be paired and connected with the external device through the Bluetooth adapter 5. A transmitting contact 5-3 is provided on the handheld terminal 5-2, and the transmitting contact 5-3 can be electrically connected to the interface terminal 5-1 through the circuit structure built into the handheld terminal 5-2. Correspondingly, a receiving contact 2-1 that is matched and connected with the transmitting contact 5-3 is provided in the inner cavity of the storage portion 2, so that when the Bluetooth adapter 5 is inserted into the interior of the storage portion 2, the transmitting contact 5-3 is electrically connected to the receiving contact 2-1. The receiving contact 2-1 is electrically connected to the wireless charging circuit 6. In this way, the Bluetooth adapter 5 can also have the function of the charging interface 7, and there is no need to change the overall appearance of the pen cover in order to set up a separate charging interface 7. Of course, although the Bluetooth adapter 5 can realize the function of the charging interface 7, the Bluetooth adapter 5 and the charging interface 7 can also coexist in certain scenarios. For example, the interface type of the charging interface 7 and the interface type of the interface end 5-1 of the Bluetooth adapter 5 can be set to different types, so that users can freely choose according to the data cable they have.

[0042] In this embodiment, the transmitting contact 5-3 on the Bluetooth adapter 5 can be set at any position of the handheld terminal 5-2, as long as the stability of the electrical connection between the transmitting contact 5-3 and the receiving contact 2-1 can be ensured. This embodiment proposes a setting method for the transmitting contact 5-3. Specifically, a contact groove is provided at the bottom of the handheld terminal 5-2. The transmitting contact 5-3 is buried in the contact groove, such as Figure 6 At the same time, a protruding receiving contact 2-1 is provided at the bottom of the inner cavity of the storage portion 2, as shown in FIG. Figure 4As shown. When the Bluetooth adapter 5 is inserted into the storage portion 2, the receiving contact 2-1 will penetrate into the contact groove and connect with the transmitting contact 5-3 in the contact groove. At this time, when the interface end 5-1 of the Bluetooth adapter 5 is connected to an external power source, the electric energy output by the external power source will be transmitted to the wireless charging circuit 6 through the Bluetooth adapter 5, triggering the wireless charging circuit 6 to enter the charging mode, and then wirelessly charging the battery inside the electronic pen 4 through the wireless charging circuit 6. It should be noted that the length of the receiving contact 2-1 should not be too long to prevent the receiving contact 2-1 from bending or breaking when the Bluetooth adapter 5 is inserted into the storage portion 2. It is best to make the receiving contact 2-1 just contact with the transmitting contact 5-3 after the Bluetooth adapter 5 is fully inserted into the storage portion 2. In order to ensure the stability of the connection between the receiving contact 2-1 and the transmitting contact 5-3, a buffer device, such as a spring, can also be set on the receiving contact 2-1 or the transmitting contact 5-3. The buffer device can not only ensure a good rigid connection between the receiving contact 2-1 and the transmitting contact 5-3, but also make the connection surface between the receiving contact 2-1 and the transmitting contact 5-3 more stable.

[0043] If the charging interface 7 provided separately can fully meet the charging needs of the user, then the Bluetooth adapter 5 proposed in this embodiment can be a conventional Bluetooth adapter 5, and there is no need to provide the transmitting contact 5-3 and the receiving contact 2-1. In this case, the Bluetooth adapter 5 can be stored in the storage portion 2 with the interface end 5-1 facing upward or with the interface end 5-1 facing downward. If the Bluetooth adapter 5 is used as the charging interface 7, then in order to facilitate the connection of the Bluetooth adapter 5 with the external device via a data cable or a power cable, it is best to store it in the storage portion 2 with the interface end 5-1 facing upward.

[0044] In addition, if Figures 7 to 11 As shown, in order to enable the user to more conveniently insert and remove the Bluetooth adapter 5 from the storage portion 2, a guide groove 5-4 is provided on the Bluetooth adapter 5 in this embodiment. The direction of the guide groove 5-4 is consistent with the length direction of the Bluetooth adapter 5. Correspondingly, a guide rib 2-2 is provided on the inner wall of the storage portion 2. The guide rib 2-2 can cooperate with the guide groove 5-4. That is, the user can insert the Bluetooth adapter 5 into the storage portion 2 by following the guide groove 5-4 on the Bluetooth adapter 5 along the guide rib 2-2 on the inner wall of the storage portion 2. Among them, the number and position of the guide groove 5-4 and the guide rib 2-2 can be set according to the shape of the Bluetooth adapter 5 and the shape of the inner cavity of the storage portion 2.

[0045] In this embodiment, the wrapping part 1, the storage part 2 and the charging part 3 can be integrally formed, or they can be independent of each other, that is, the wrapping part 1, the storage part 2 and the charging part 3 are all detachably connected to each other. In this way, the user can select the components with separate functions according to actual needs, which fully enhances the functionality and convenience of the pen cover proposed in this embodiment.

[0046] Example 2

[0047] This embodiment provides a writing device, which includes an electronic pen 4 and a pen cover mounted on the electronic pen 4. The structure of the pen cover can refer to the content described in Embodiment 1, and will not be described in detail in this embodiment.

[0048] The pen cover proposed in this embodiment can be mounted on the tip of the electronic pen 4 to protect the tip of the pen. At the same time, a Bluetooth adapter 5 that can be freely stored in the pen cover is also provided on the pen cover to bind the Bluetooth adapter 5 and the electronic pen 4. Thus, when the user uses the electronic pen 4, it is convenient to take the Bluetooth adapter 5.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
