[0036] The realization, functional features and advantages of the purpose of the present utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0038] The stylus is an important input accessory for electronic products. The stylus has a nib end, a pen barrel, and a tail. Generally, a cover is provided at the tail, and the cover is used to protect the connection terminals of the stylus. The stability of the structure at the tail of the stylus directly affects the charging performance and service life of the stylus. The cover of the stylus can be slidably connected to the pen barrel, and the connection terminals can be exposed by sliding the cover during use. The cover of the stylus can also be snap-connected to the pen barrel, and the cover can be directly separated from the pen barrel during use. In the prior art, whether it is a cover that is slidably connected to the pen barrel or a cover that is snap-connected to the pen barrel, within the opening and closing stroke of the cover, the impact force between the cover and the pen barrel is generally large, the electrical connection of the connection terminals and the like is likely to be disconnected, and the structure at the tail of the stylus is easily damaged.

[0039] To solve the above technical problems, as Figures 1 to 6 shown, the present application proposes a cover assembly 100, and the cover assembly 100 includes a base body 110 and a cover 120.

[0040] As Figure 1 , Figure 2 and Figure 3 shown, the base body 110 includes a connection portion 111 and a first limiting portion 112, and the connection portion 111 is provided with electrical connection terminals. The connection portion 111 is used for external electrical connection so that the cover assembly 100 can perform charging and discharging or information transmission with the outside world. The connection portion 111 can be configured as any suitable interface such as a Type-A interface (Universal Serial Bus Type-A interface), a Type-B interface (Universal Serial Bus Type-B interface), a Type-C interface (Universal Serial Bus Type-C interface), a Micro-USB interface (Miniature Universal Serial Bus interface), or a Lightning interface (Lightning interface).

[0041] As Figure 2 , Figure 3 and Figure 4As shown, the cover body 120 and the base body 110 are oppositely arranged along the first direction X. The cover body 120 includes a second limiting portion 121. The cover body 120 defines a first accommodating cavity 122. The connecting portion 111 can pass through the first accommodating cavity 122. The cover body 120 can move relative to the base body 110 along the first direction X so that the connecting portion 111 is exposed from the cover body 120. The second limiting portion 121 cooperates with the first limiting portion 112 to limit the movement of the cover body 120 within the stroke in the first direction X. The first limiting portion 112 and the second limiting portion 121 can limit the relative movement between the cover body 120 and the base body 110 by enhancing the damping between the cover body 120 and the base body 110. Specifically, the first limiting portion 112 and the second limiting portion 121 can increase the friction coefficient between the base body 110 and the cover body 120 to increase the frictional force between the cover body 120 and the base body 110. The first limiting portion 112 and the second limiting portion 121 can also increase the acting force between the cover body 120 and the base body 110 to increase the frictional force between the cover body 120 and the base body 110. The first limiting portion 112 and the second limiting portion 121 can limit the relative movement between the cover body 120 and the base body 110 by adding clamping points within the stroke.

[0042] In the technical solution of the present application, the cover body 120 is connected to the base body 110. The cover body 120 can move relative to the base body 110. The movement states of the cover body 120 include an open cover movement state away from the base along the first direction X and a closed movement state close to the base in the reverse direction of the first direction X. The base body 110 has a first limiting portion 112, and the cover body 120 has a second limiting portion 121. The first limiting portion 112 and the second limiting portion 121 cooperate with each other to limit the movement of the cover body 120 relative to the base body 110. Due to the arrangement of the first limiting portion 112 and the second limiting portion 121, the cover body 120 can stop at any position within the formation. The user can switch the open cover and closed states at any time within the formation. Thanks to the protection of the first limiting portion 112 and the second limiting portion 121, when the cover body 120 switches states, the vibration inside the cover body assembly 100 is small, the risk of damage to the cover body 120 is greatly reduced, and the service life of the cover body assembly 100 is greatly extended. In addition, the arrangement of the first limiting portion 112 and the second limiting portion 121 makes the cover body 120 more stable when opening or closing, preventing accidental ejection or incomplete closing caused by the cover body 120 being too fast or too slow, and reducing accidental operations.

[0043] The ways in which the first limiting portion 112 and the second limiting portion 121 limit the movement of the cover body 120 can be set according to different usage requirements. Such as Figure 3 and Figure 4As shown, in some embodiments, the first limiting portion 112 and the second limiting portion 121 can be configured as structures capable of magnetic interaction with each other to limit the movement of the cover 120 through the action of the magnetic field. The first limiting portion 112 and the second limiting portion 121 can increase the force perpendicular to the first direction X between the cover 120 and the base 110 through the mutual attraction of the magnetic field to limit the movement of the cover 120. In some embodiments, the first limiting portion 112 is configured as a magnet, and the second limiting portion 121 is configured as a material responsive to the magnetic field. In some embodiments, the first limiting portion 112 is configured as a material responsive to the magnetic field, and the second limiting portion 121 is configured as a magnet. Specifically, the magnet can be an electromagnet or a permanent magnet. The material responsive to the magnetic field can be iron, nickel, cobalt, and their alloys and compounds. The material responsive to the magnetic field can be a hard magnetic material, a soft magnetic material, or a rectangular magnetic material, as long as the first limiting portion 112 and the second limiting portion 121 can jointly limit the movement of the cover 120 relative to the base and reduce the impact force between the cover 120 and the base 110. In some embodiments, both the first limiting portion 112 and the second limiting portion 121 are configured as magnets. Among them, the magnetic pole polarity of the side of the first limiting portion 112 close to the second limiting portion 121 is opposite to the magnetic pole polarity of the side of the second limiting portion 121 close to the first limiting portion 112. Specifically, if the magnetic property of the side of the magnet of the first limiting portion 112 close to the second limiting portion 121 is the north pole, then the magnetic property of the side of the magnet of the second limiting portion 121 close to the first limiting portion 112 is the south pole. Conversely, the magnetic pole polarity of the side of the first limiting portion 112 close to the second limiting portion 121 can also be the south pole, and the magnetic pole polarity of the side of the second limiting portion 121 close to the first limiting portion 112 is the north pole. Thanks to the application of the magnet, the sliding damping effect between the cover 120 and the base 110 is significantly improved. The damping force generated by the magnetic field is beneficial to controlling the movement speed when the cover 120 is opened and closed, reducing unnecessary vibrations and noises, and further stabilizing the movement state of the system to prevent system failure or performance degradation caused by excessive vibrations. The interaction between the magnet and the magnetic material can precisely control the opening and closing strokes of the pen cap, improving the accuracy and stability of the user during use and preventing the pen cap from accidentally opening or closing.

[0044] In different embodiments, the positions of the first limiting portion 112 and the second limiting portion 121 can be different according to the settings of the cover 120 and the base 110. For example Figure 2 and Figure 3As shown, in some embodiments, the base 110 also includes a rod body 113 and a bracket 114, the bracket 114 is connected to the rod body 113, the third direction Y intersects with the first direction X, the bracket 114 defines a connecting port 1141 opening toward the third direction Y, the connecting portion 111 is arranged at the connecting port 1141, the first limiting portion 112 is connected to an end of the bracket 114 away from the rod body 113, the second limiting portion 121 extends along the first direction X and is penetrated in the first accommodating cavity 122, that is, the connecting portion 111 is connected to the bracket 114, and the connecting portion 111 is arranged on a side of the first limiting portion 112 close to the rod body 113. Preferably, the third direction Y can be perpendicular to the first direction X, that is, the connection port 1141 is arranged on the side of the bracket 114, and the cover 120 does not need to be completely separated from the base to expose the connection portion 111, thereby avoiding the separation of the cover 120 and the base 110, improving the convenience of use of the cover 120, and greatly reducing the possibility of losing the cover 120. The first limiting portion 112 is arranged at the end of the bracket 114. When the cover 120 is buckled on the base 110, the first limiting portion 112 is also located in the first accommodating cavity 122. Since the second limiting portion 121 is penetrated in the first accommodating cavity 122, the first limiting portion 112 and the second limiting portion 121 can be stably contacted during the movement of the cover 120. Preferably, the second limiting portion 121 can pass through and be exposed in the first accommodating cavity 122 , and when the cover 120 is buckled on the base, the second limiting portion 121 can pass through the base 110 to enhance the connection stability between the base 110 and the cover 120 .

[0045] In different embodiments, the number of components of the first limiting portion 112 and the second limiting portion 121 may be different. Figure 3 as well as Figure 4 As shown, in some embodiments, the first limiting portion 112 includes a first limiting member 1121 and a second limiting member 1122, the second direction Z intersects with the first direction X, the first limiting member 1121 and the second limiting member 1122 are arranged relatively along the second direction Z, the second limiting portion 121 includes a first sensing member 1211 and a second sensing member 1212 arranged relatively along the second direction Z, and the second limiting portion 121 is sleeved on the bracket 114 so that the first limiting member 1121 senses the first sensing member 1211, and the second limiting member 1122 senses the second sensing member 1212. The second direction Z can be perpendicular to the first direction X, preferably, the second direction Z is perpendicular to the first direction X and the third direction Y. The first sensing member 1211 can be integrally formed with the second sensing member 1212. The first limiting portion 112 and the second limiting portion 121 can be respectively set as a plurality of one-to-one corresponding sensing components to further improve the movement stability of the cover body 120.

[0046] Due to the characteristics of the magnet, the first limiting portion 112 and the second limiting portion 121 may not be in direct contact, and the magnetic force between the first limiting portion 112 and the second limiting portion 121 can still limit the movement of the cover 120. Figure 3 as well as Figure 4 As shown, in some embodiments, the end of the bracket 114 away from the rod body 113 defines a second accommodating cavity 1142, and the first limiting portion 112 is disposed in the second accommodating cavity 1142, so that the first limiting portion 112 is spaced apart from the second limiting portion 121. The first limiting portion 112 is spaced apart from the second limiting portion 121, so that the connection surface between the cover body 120 and the base 110 can be smoother, reduce mechanical wear between the cover body 120 and the base, and increase the service life of the cover body 120.

[0047] To further improve the connection stability when the cover 120 is closed on the base 110, as Figure 4 as well as Figure 5 As shown, in some embodiments, the cover 120 further includes a third limiting portion 123, and the third limiting portion 123 is arranged in the accommodating cavity. When the cover 120 moves in the reverse direction of the first direction X and is buckled with the base 110, the first limiting portion 112 can attract each other with the third limiting portion 123. Specifically, the third limiting portion 123 can be connected to the second limiting portion 121 or to the outer shell 124 of the cover 120, as long as the third limiting portion 123 can attract each other with the first limiting portion 112 when the cover 120 is buckled with the base 110. Specifically, if the first limiting portion 112 is configured as a magnet, the third limiting portion 123 can be configured as a magnet that can attract each other or other materials that can respond to a magnetic field. If the first limiting portion 112 is configured as a material that can respond to a magnetic field, the third limiting portion 123 can be configured as a magnet, which is not limited here.

[0048] like Figure 4 as well as Figure 5As shown, to further improve the protection of the connecting portion 111 and reduce the risk of damage to the connecting portion 111, the base body 110 may further be provided with an inner housing 115. Accordingly, the inner housing 115 can be inserted into the accommodating cavity to further improve the connection stability between the cover body 120 and the base body 110. In order to reduce the loss of the cover body 120, the inner housing 115 can be spaced apart from the second limiting portion 121. In some embodiments, the base body 110 further includes an inner housing 115, and the inner housing 115 is sleeved on the bracket 114. The cover body 120 further includes an outer housing 124, and the second limiting portion 121 is connected to the outer housing 124. The outer housing 124 defines a first accommodating cavity 122, and the second limiting portion 121 is inserted into the first accommodating cavity 122, so that the first accommodating cavity 122 is divided into an inner cavity 1221 and an outer cavity 1222. The outer cavity 1222 is located on the side of the second limiting portion 121 close to the outer housing 124, and the inner cavity 1221 is located on the side of the second limiting portion 121 away from the outer housing 124. The bracket 114 can be inserted into the inner cavity 1221, and the inner housing 115 can be inserted into the outer cavity 1222; wherein, along the first direction X and / or along the direction perpendicular to the first direction X, the inner housing 115 is spaced apart from the second limiting portion 121. That is to say, an assembly gap is reserved between the inner housing 115 and the second limiting portion 121. The outer housing 124 can be in contact with the inner housing 115, and the outer housing 124 can also be in contact with other housings of the base except the inner housing 115 to improve the sealing performance of the outer housing 124, which is not limited here.

[0049] In some embodiments, the first limiting portion 112 and the second limiting portion 121 may further be provided with a plurality of clamping points to limit the relative movement between the cover body 120 and the base body 110 and increase the damping when the cover body 120 and the base body 110 move relative to each other. As Figure 6 shown, in some embodiments, the first limiting portion 112 is configured as a first protrusion 1123, and the first protrusion 1123 is provided at one end of the base body 110 close to the cover body 120. The second limiting portion 121 is configured as a plurality of second protrusions 1213 spaced apart along the first direction X. The first protrusion 1123 can be clamped in the gap between the second protrusions 1213 to limit the movement of the cover body 120. As Figure 5As shown, in some embodiments, the first limiting portion 112 is configured as a plurality of third protrusions 1124 spaced along the first direction X, and the second limiting portion 121 is configured as a fourth protrusion 1214. The fourth protrusion 1214 is provided at one end of the cover body 120 close to the base body 110. The fourth protrusion 1214 can be clamped in the gap between the third protrusions 1124 to limit the movement of the cover body 120. It can be understood that each protrusion can be integrally formed on the base or other connecting parts 111 of the cover body 120, which is not limited here. The arrangement of the second protrusion 1213 and the third protrusion 1124 enables the cover body 120 to stop at any position within the stroke on the one hand. The groove between the protrusions spaced along the first direction X can also reduce the opening angle of the second limiting portion 121 in the direction perpendicular to the first direction X, reducing the risk of fatigue fracture of the second limiting portion 121. It can be understood that in some embodiments, the first limiting portion 112 can be configured with a plurality of protrusions spaced along the first direction X, and the second limiting portion 121 can also be configured as a plurality of protrusions spaced along the first direction X. The protrusions of the first limiting portion 112 are adapted to be respectively clamped in the gaps between the protrusions of the second limiting portion 121. The arrangement of the plurality of protrusions can further reduce the risk of wear failure between the first limiting portion 112 and the second limiting portion 121. It should be noted that in some embodiments, the cover body assembly 100 can only be provided with the first protrusion 1123, the third protrusion 1124 or configure the first limiting portion 112 as a magnet to improve the movement stability of the cover body 120 and reduce the risk of damage to each component of the cover body assembly 100. In some embodiments, as Figure 5 shown, the cover body assembly 100 can also have the aforementioned protrusions and magnets at the same time, and the two together improve the movement stability of the cover body 120, which will not be elaborated here.
