It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. Moreover, in order to provide a clearer description and easier understanding of the present application, the parts in the drawings are not drawn according to their relative dimensions, some dimensions have been exaggerated compared to other relevant dimensions; irrelevant details are not fully drawn for the sake of brevity.
Example 1
As shown in fig. 1, the present embodiment provides a pen cap, which includes a wrapping portion 1 and a receiving portion 2, where the wrapping portion 1 is a cylindrical structure with a closed top and is used for wrapping a pen tip of an electronic pen 4. The tip of the electronic pen 4 can be inserted into the wrapping part 1 from the bottom of the wrapping part 1. The storage part 2 is fixed on the side surface of the wrapping part 1 and used for storing the Bluetooth adapter 5. The interior of the housing 2 is hollow, and the top of the housing 2 is open. The bluetooth adapter 5 is inserted into the housing 2 from the top of the housing 2, as shown in fig. 2.
Specifically, in this embodiment, the entire pen cap may be divided into a wrapping portion 1 and a receiving portion 2. The wrapping part 1 is a cylindrical structure with a closed top. The shape of the inner cavity of the wrapping part 1 can be correspondingly designed according to the shape of the pen point of the electronic pen 4, and a certain friction force is ensured to be kept between the inner cavity of the wrapping part 1 and the contact part of the pen point as far as possible so as to prevent the pen cap from falling off. The pen body of the electronic pen 4 can be provided with external threads, and the inner wall of the wrapping part 1 is provided with internal threads, so that the wrapping part 1 can be connected with the electronic pen 4 through threads. Meanwhile, the pen point of the common electronic pen 4 is mostly in a cone structure, and under the structure, the stability between the inner cavity of the wrapping part 1 and the pen point is poor. Therefore, the length of the pen cap can be increased in the embodiment, so that the pen cap is in contact with the pen body, and the stability of the pen cap on the electronic pen 4 is ensured. A buffer layer may be further provided on the inner wall of the wrapping portion 1. The buffer layer can be made of soft materials such as rubber and sponge, and further has the function of protecting the pen point of the electronic pen 4.
A storage section 2 is provided on a side surface of the wrapping section 1. The storage part 2 is open at the top and hollow inside, and is used for storing the bluetooth adapter 5. The bluetooth adapter 5 may be inserted into the inner cavity of the housing 2 from the top of the housing 2, as shown in fig. 2. The inner cavity of the receiving portion 2 may be designed according to the overall shape of the bluetooth adapter 5. The inner cavity of the receiving part 2 and the contact part of the outer surface of the Bluetooth adapter 5 also have certain friction force. The bluetooth adapter 5 can be plugged into an external device, so that the electronic pen 4 is connected with the external device in a pairing manner through the bluetooth adapter 5, and then a user can perform related operations on the external device by using the electronic pen 4. In this embodiment, the accommodation between the bluetooth adapter 5 and the accommodation portion 2 can also be realized by magnetic attraction or a buckle.
The embodiment can effectively protect the pen point of the electronic pen 4 through the pen cap so as to prevent the pen point from being damaged due to contact with an external hard object. Meanwhile, the electronic pen 4 and the Bluetooth adapter 5 can be integrated together, so that the electronic pen is convenient for a user to carry and use at the same time.
Further, the pen cap described in the present embodiment further includes a charging unit 3. The charging unit 3 is provided below the housing unit 2 and is located as close as possible to the body of the electronic pen 4. The charging unit 3 incorporates a wireless charging circuit 6. A charging port is opened in the charging unit 3, and a charging port 7 is provided in the charging port, as shown in fig. 2. The charging interface 7 can be connected with an external power supply and simultaneously electrically connected with the wireless charging circuit 6, so that electric energy output by the external power supply is transmitted to the wireless charging circuit 6 through the charging interface 7, and the wireless charging circuit 6 wirelessly charges a battery in the electronic pen 4. In order to enable the wireless charging circuit 6 to wirelessly charge the battery inside the electronic pen 4, several preconditions need to be ensured. First, the battery inside the electronic pen 4 must be a wirelessly rechargeable battery. Secondly, the wireless charging circuit 6 is close to the battery as much as possible to ensure the stability and effectiveness of charging.
In addition, in the present embodiment, the whole charging unit 3 is in a strip shape, and the contact portion between the charging unit 3 and the receiving unit 2 is made to be a bendable structure. For example, a material having a relatively soft material may be used as a connecting member between the charging unit 3 and the housing unit 2, or the charging unit 3 and the housing unit 2 may be connected by a hinge. Thus, the whole charging part 3 can also be used as a pen clip, so that a user can clip the electronic pen on clothes or a pocket through the charging part 3 conveniently.
Of course, in the present embodiment, the position of the charging unit 3 is not limited to the above position, and may be determined according to the overall design of the electronic pen 4 and the installation position of the battery inside the electronic pen 4. In addition, the position of the charging interface 7 electrically connected to the wireless charging circuit 6 may be set at other positions, for example, on the wrapping portion 1 or the housing portion 2, as shown in fig. 3, as long as reliable electrical connection between the wireless charging circuit 6 and the charging interface 7 is ensured.
Further, as shown in fig. 5, the bluetooth adapter 5 proposed in the present embodiment includes an interface terminal 5-1 and a handheld terminal 5-2. Interface end 5-1 may be used to connect with an external device. The hand-held end 5-2 can be inserted into the interior of the housing 2 from the top of the housing 2. The handheld end 5-2 is internally provided with a circuit structure which can realize circuit connection and signal transmission with the interface end 5-1, so that the electronic pen 4 is connected with external equipment in a matching way through the Bluetooth adapter 5. A transmitting contact 5-3 is arranged on the hand-held end 5-2, and the transmitting contact 5-3 can be electrically connected with the interface end 5-1 through a circuit structure built in the hand-held end 5-2. Correspondingly, a receiving contact 2-1 matched and connected with the transmitting contact 5-3 is arranged in the inner cavity of the accommodating part 2, so that when the Bluetooth adapter 5 is inserted into the inner part of the accommodating part 2, the transmitting contact 5-3 is electrically connected with the receiving contact 2-1. The receiving contact 2-1 is electrically connected with the wireless charging circuit 6. Therefore, the Bluetooth adapter 5 has the function of the charging interface 7 at the same time, and the overall appearance of the pen cap does not need to be changed for arranging the separate charging interface 7. Of course, although the bluetooth adapter 5 may realize the function of the charging interface 7, the bluetooth adapter 5 and the charging interface 7 may coexist in a certain scenario. For example, the interface type of the charging interface 7 and the interface type of the interface terminal 5-1 of the bluetooth adapter 5 may be set to be different types, so that a user can freely select the interface type according to a data line owned by the user.
In this embodiment, the transmitting contact 5-3 of the bluetooth adapter 5 can be disposed 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. The present embodiment proposes an arrangement of the emitter contacts 5-3. Specifically, a contact groove is formed in the bottom of the handheld end 5-2. The transmitting contact 5-3 is buried in the contact groove as shown in fig. 6. Meanwhile, a receiving contact 2-1 is provided at the bottom of the inner cavity of the receiving part 2 to protrude, as shown in fig. 4. When the bluetooth adapter 5 is inserted into the receiving part 2, the receiving contact 2-1 penetrates into the contact recess and is connected with the transmitting contact 5-3 in the contact recess. At this time, when the interface terminal 5-1 of the bluetooth adapter 5 is connected to the external power supply, the electric energy output by the external power supply is transmitted to the wireless charging circuit 6 through the bluetooth adapter 5, the wireless charging circuit 6 is triggered to enter a charging mode, and then the wireless charging is performed on 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 is not too long, so as to prevent the receiving contact 2-1 from being bent or broken when the bluetooth adapter 5 is inserted into the receiving portion 2, and preferably, the receiving contact 2-1 is just contacted with the transmitting contact 5-3 after the bluetooth adapter 5 is completely inserted into the receiving 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, may be disposed on the receiving contact 2-1 or the transmitting contact 5-3, and the buffer device may ensure a good rigid connection between the receiving contact 2-1 and the transmitting contact 5-3, or may stabilize the connection surface between the receiving contact 2-1 and the transmitting contact 5-3.
If the separately provided charging interface 7 can fully meet the charging requirement of the user, the bluetooth adapter 5 proposed in the present embodiment may be a conventional bluetooth adapter 5 without providing the transmitting contact 5-3 and the receiving contact 2-1. At this time, the bluetooth adapter 5 can be housed in the housing portion 2 with the interface end 5-1 facing upward or the interface end 5-1 facing downward. If the bluetooth adapter 5 is used as the charging interface 7, it is preferable that the interface terminal 5-1 is upwardly received in the receiving portion 2 in order to facilitate connection of the bluetooth adapter 5 to an external device through a data line or a power line.
Further, as shown in fig. 7 to 11, in order to enable the user to insert and extract the bluetooth adapter 5 from the storage part 2 more conveniently, the present embodiment is provided with a guide groove 5-4 on the bluetooth adapter 5. The direction of the guide groove 5-4 is in accordance with the length direction of the bluetooth adapter 5. Correspondingly, the inner wall of the containing part 2 is provided with a guide rib 2-2. The guide ribs 2-2 can cooperate with the guide grooves 5-4. That is, the user can insert the bluetooth adapter 5 into the receiving portion 2 by guiding the guiding groove 5-4 of the bluetooth adapter 5 along the guiding rib 2-2 on the inner wall of the receiving portion 2. The number and the positions of the guide grooves 5-4 and the guide ribs 2-2 can be set according to the shape of the Bluetooth adapter 5 and the shape of the inner cavity of the accommodating part 2.
In this embodiment, the wrapping portion 1, the receiving portion 2 and the charging portion 3 may be integrally formed, or may be mutually independent, that is, the wrapping portion 1, the receiving portion 2 and the charging portion 3 are detachably connected. Therefore, the user can select the components with the independent functions for use according to actual needs, and the functionality and the convenience of the pen cap provided by the embodiment are fully enhanced.
