Referring to fig. 1 to 3, a first aspect of the present disclosure provides a charging box 100 including a main body portion 1, an electrical contact 3. The main body portion 1 includes an inner cavity 121, a charging cavity 113, and a first opening 111 communicating the inner cavity 121 and the charging cavity 113. The electrical contact 3 is accommodated in the inner cavity 121, partially penetrates through the first opening 111 and is exposed in the charging cavity 113. The charging cavity 113 is used for accommodating a device to be charged, such as a TWS headset, a mobile phone, a tablet and the like, which is matched with the charging box 100. When the device to be charged is accommodated in the charging cavity 113, the metal sheet on the device to be charged contacts with the electrical contact 3, so that the charging of the device to be charged is realized. And, when the device to be charged does not need to be used, the device to be charged can be placed in the charging cavity 113, so that the device to be charged can be accommodated.

The charging box 100 may be a small-sized portable charging box 100, and a user may charge the charging box 100 in advance, and may also charge the device to be charged when the charging box 100 is subsequently carried. Or, the charging box 100 may also be a charging box 100 with a larger volume, for example, the charging box 100 may be a mobile phone charging box 100 placed on a desktop, the charging box 100 is electrically connected to a power supply, and when the device to be charged needs to be charged, the device to be charged is placed in the charging box 100, so that the charging function can be realized.

In some embodiments, the body portion 1 includes a first housing 11 and a second housing 12; the second housing 12 includes a second housing wall 123, the second housing wall 123 enclosing an internal cavity 121. The first housing 11 is at least partially disposed in the inner cavity 121, and is connected to the second housing 12 to close the opening, wherein the first opening 111 is disposed in the first housing 11. In this manner, the circuit components of the charging box 100 can be accommodated in the inner cavity 121, and since the first housing 11 and the second housing 12 are connected to close the opening portion, the main body portion 1 can provide a certain protection against water and dust for the circuit components.

In some embodiments, the first housing 11 and the second housing 12 may be connected by a snap connection, so as to improve the connection stability between the first housing 11 and the second housing 12. In other embodiments, the first housing 11 and the second housing 12 are further connected by an adhesive such as glue, so as to fill the gap between the first housing 11 and the second housing 12 to some extent and improve the sealing performance of the inner cavity 121.

In some embodiments, the charging box 100 is an open type charging box 100 in which the charging cavity 113 is exposed to the outside, thereby facilitating a user to take out or put in the device to be charged from the charging box 100. In other embodiments, the charging box 100 further includes a cover 2, the cover 2 is pivotally connected to the main body 1 and is used for opening or closing the charging cavity 113, so that the charging cavity 113 can be pivotally closed when a user does not need to use the charging box 100, and liquid dust and the like are prevented from entering the inner cavity 121 through the charging cavity 113; or when the device to be charged is placed in the charging cavity 113, closing the charging cavity 113 by pivoting the lid body 2 can avoid the device to be charged from leaving the charging cavity 113 during carrying the charging box 100, resulting in poor charging effect or even the possibility of losing the device to be charged.

In some embodiments, the main body portion 1 includes an end surface 122, and the end surface 122 is disposed obliquely with respect to a plane perpendicular to the height H direction of the main body portion 1, as shown in fig. 1. With this, the entire main body portion 1 is in the form of the first opening 111 inclined in the thickness direction, so that the charging chamber 113 is exposed to a greater extent, and it is further convenient to put a device to be charged into the charging chamber 113 or take the device to be charged out of the charging chamber 113. And, because the chamber 113 that charges is exposed by bigger degree, can convenience of customers from the outside wipe the chamber 113 that charges, not only can promote the whole health nature of box 100 that charges, can also avoid impurity to remain in the chamber 113 that charges through outside wiping when there are impurity such as liquid, dust in the chamber 113 that charges, then get into the sealed chamber in the middle of, cause the corruption to the mainboard, or make the mainboard short circuit.

When the device to be charged is taken out of or put into the charging chamber 113, friction or collision with the charging chamber 113 is inevitably generated, so that abrasion marks are formed on the charging chamber 113 and the device to be charged, and the appearance is affected. When the device to be charged is placed in the charging chamber 113, there is a gap between the device to be charged and the wall surface of the charging chamber 113. The position where the gap is the smallest is called the highest point of the charging cavity 113, and since the gap between the device to be charged and the highest point is small, even no gap exists, the device to be charged is likely to collide with the highest point in the process of storing and taking out the device to be charged. For the devices to be charged of the same model and the charging boxes 100 of the same model, because the process difference can lead to the difference of the surface shapes of the devices to be charged or the charging boxes 100 to a certain extent, and the difference of the surface shapes leads to the difference of the positions worn on the inner wall of the charging cavity 113 when the devices to be charged are matched with the charging boxes 100, it is difficult to take measures to the established wear positions to avoid the friction between the inner wall of the charging cavity 113 and the devices to be charged, and the wear problem caused by the process error can not be solved in a large batch.

Based on this, the present disclosure proposes a charging box 100, which may cause a wear problem when adapting to devices to be charged of the same model with slight process errors on the surface, so that the charging box 100 may be adapted to a large number of devices to be charged, thereby reducing market complaints. Specifically, the charging box 100 of the present disclosure includes a projection 112. The boss 112 is provided on the inner wall of the charging chamber 113 near the electrical contact 3. When the electrical contact 3 is in contact with the device to be charged for charging, the projection 112 is in contact with the device to be charged. Since the device to be charged is in contact with the electrical contact 3 at the position where the electrical contact 3 is provided in the charging chamber 113, the electrical contact 3 jacks up the device to be charged. Therefore, at this position, the device to be charged and the wall surface of the charging chamber 113 must have a gap and do not contact each other. In other words, no matter what shape of the charging cavity 113 or what shape of the device to be charged is matched, the position or the vicinity of the charging cavity 113 where the electrical contact 3 is provided is not the highest point, i.e., the gap between the position or the vicinity of the position where the electrical contact 3 is provided and the device to be charged is not the minimum gap.

Based on this, according to the present disclosure, the protrusion 112 is disposed at a position that is not the highest point and can be determined, so that when the device to be charged contacts the electrical contact 3 for charging, the device to be charged can be jacked up by the protrusion 112, a gap between another area of the device to be charged and the inner wall of the charging cavity 113 is increased, and a worn position is controlled at the protrusion 112, which is beneficial to reducing wear of the device to be charged to another position of the inner wall of the charging cavity 113 in the storage and taking-out processes, and meanwhile, because the protrusion 112 is disposed close to the electrical contact 3, effective contact conduction between the electrical contact 3 and the device to be charged is more easily ensured compared with the case that the protrusion 112 is disposed at another position that may itself be the highest point of the inner wall of the charging cavity 113.

In the above embodiment, the charging box 100 may include one or more protruding portions 112, and when the charging box 100 includes a plurality of protruding portions 112, each of the plurality of protruding portions 112 may contact the device to be charged when the electrical contact 3 contacts the device to be charged, and the device to be charged may be supported by a plurality of supporting points, which is advantageous for supporting the device to be charged in a balanced manner in a case where a supporting area of a single protruding portion 112 is small. The surface that bellying 112 deviates from the 113 inner walls of charging chamber can be the slope setting, and when electric contact 3 contacted with the equipment of waiting to charge, the surface that should be the slope setting can with wait the corresponding inclined surface contact of equipment of charging, or the corresponding surface of the equipment of waiting to charge can be the plane setting, consequently can reduce bellying 112 and wait the area of contact between the equipment of charging to reduce friction area, further reduce the surperficial scratch of bellying 112.

In some embodiments, the height H of the protrusion 112 from the surface of the charging cavity 113 is greater than or equal to 0.05mm and less than or equal to 0.15mm, so as to reduce the presence of the protrusion 112 and avoid affecting the aesthetic appearance of the charging box 100. In addition, be provided with magnet or magnetic part in charging chamber 113 and will treat the charging apparatus in the embodiment of charging chamber 113, the too big adsorption affinity that probably leads to magnet or magnetic part to treat the charging apparatus of bellying height H reduces, consequently this disclosure is through reasonable setting up protruding height H, can be on the basis that does not influence magnet or magnetic part and treat the adsorption affinity of charging apparatus for treat the charging apparatus of charging apparatus and keep certain clearance with charging chamber 113 inner wall, avoid leading to wearing and tearing with charging chamber 113's inner wall looks mutual friction.

As shown in fig. 3, in order to ensure the contact between the device to be charged and the electrical contact 3, when the electrical contact 3 is not in contact with the device to be charged, the electrical contact 3 protrudes relative to the contact surface 116 and extends into the charging cavity 113, so that it can be ensured that the electrical contact 3 can be in contact with the device to be charged when the device to be charged abuts against the contact surface 116, and the charging effect of the charging box 100 on the device to be charged is ensured.

To further reduce the visibility of wear, in some embodiments, the contact surface 116 of the boss 112 that contacts the device to be charged has a surface roughness that is greater than the surface roughness of the inner wall of the charging cavity 113. For aesthetic reasons, the inner walls of the charging chamber 113 are usually configured as mirror surfaces, and thus have a low surface roughness. Once scratches or abrasion occurs on the inner wall of the charging chamber 113, scratches or abrasion traces become very noticeable. Therefore, the present disclosure can hide the wear trace to some extent by increasing the surface roughness of the contact surface 116, and maintain the freshness of the appearance of the charging box 100, even if the device to be charged is worn by long-term contact with the contact surface 116.

Referring to fig. 3, in some embodiments, the protrusion 112 is integrally formed with the body part 1, thereby improving the structural strength of the protrusion 112 and enabling the protrusion 112 to maintain the uniformity of the appearance with the charging chamber 113. The first opening 111 penetrates through the protruding portion 112 and the shell wall of the main body portion 1 to communicate the inner cavity 121 and the charging cavity 113, so that the electrical contact 3 can be partially exposed in the charging cavity 113, and subsequent contact with a device to be charged is ensured, and a charging effect of the device to be charged is ensured.

Referring to fig. 4, in other embodiments, the body portion 1 further includes a groove 114 formed to be recessed inward from an inner wall of the charging chamber 113. The protrusion 112 is inserted into the groove 114 to be disposed on the inwardly recessed inner wall of the charging chamber 113, and the height H of the protrusion 112 is greater than the depth of the groove 114. In this way, when the subsequent protruding portion 112 is worn seriously, the charging box 100 can have a relatively good appearance by replacing the new protruding portion 112 without replacing the entire main body portion 1.

The protruding portion 112 may be in an interference fit with the groove 114, so as to prevent the protruding portion 112 from falling off due to unavoidable external vibration or impact when the user carries the charging box 100, or prevent the protruding portion 112 from falling off due to stress when the device to be charged is placed in the charging cavity 113 or taken out of the charging cavity 113.

In this embodiment, the protruding portion 112 includes a second opening 115 arranged coaxially with the first opening 111, so that the charging cavity 113 and the inner cavity 121 can communicate with each other through the first opening 111 and the second opening 115, and the electrical contact 3 can be partially exposed in the charging cavity 113, thereby ensuring subsequent contact with the device to be charged, and further ensuring the charging effect of the device to be charged.

In some embodiments, boss 112 comprises a flexible boss. A flexible layer may be applied to the surface of the raised portion 112 to form a flexible raised portion. Alternatively, in embodiments where the raised portion 112 is disposed in the recess 114, the flexible raised portion may be made entirely of a flexible material. Due to the characteristic of easy deformation of the flexible material, when the device to be charged rubs against the flexible protruding part, the flexible protruding part is difficult to leave obvious scratches on the surface of the device to be charged. In addition, the flexible material has good wear resistance, and can prolong the wear resistance and the service life of the convex part 112. The flexible protrusions may include rubber protrusions, silicone protrusions, and the like, and the present disclosure is not limited thereto.

Referring to fig. 4, the arrangement of the protrusions 112 may include various ways, thereby improving design flexibility of the external appearance of the charging pouch 100. In some embodiments, the projections 112 are provided around the outer periphery of the electrical contact 3, as shown in (a) and (b) in fig. 5. Wherein in the embodiment shown in (a), the charging box 100 includes a plurality of electrical contacts 3 and one projection 112, and the projection 112 is provided around all of the electrical contacts 3. In the embodiment in which the positions between the plurality of electrical contacts 3 are closer, providing one protrusion 112 to surround all the electrical contacts 3 as a whole can reduce the processing difficulty, increase the area of the contact surface 116 of the protrusion 112, and also can make the appearance of the charging box 100 as a whole simpler. In the embodiment shown in (b), the charging box 100 includes a plurality of electrical contacts 3 and a plurality of projections 112, each projection 112 being disposed around each electrical contact 3. In the embodiment in which the positions between the plurality of electrical contacts 3 are distant, providing the projection 112 separately for each electrical contact 3 can minimize the sense of presence of the projection 112, ensuring the aesthetic appearance of the charging box 100.

In other embodiments, the protrusions 112 are arranged in a strip shape, and the edges of the protrusions 112 are in contact with the outer surface of the electrical contact 3. Referring to (c) and (d) in fig. 5, the convex portion 112 may be disposed on both sides of the electrical contact 3, or between a plurality of electrical contacts 3, which not only can reduce the area of the contact surface 116 of the convex portion 112 compared to the embodiments of (a) and (b), but also can provide a more balanced and stable supporting effect.

It should be noted that, in the embodiment shown in fig. 5, the number of the electrical contacts 3 and the raised portions 112 should be taken as an example and not a limitation, and a person skilled in the art may set the number of the electrical contacts 3 as required, for example, one, two, three, etc., and the disclosure is not limited thereto. Further, in the embodiment of the plurality of electrical contacts 3, the projection 112 may be provided for each electrical contact 3, or only a part of the electrical contacts 3 may be provided with the projection 112, and the present disclosure is not limited. As for the arrangement manner of the protrusion 112, there may be a plurality of protrusions 112 in one charging cartridge 100, and the arrangement manner of each protrusion 112 may be the same or may be different, which is not limited by the present disclosure.

Referring to fig. 5 and 6, a second aspect of the present disclosure provides a device assembly 200 comprising a device to be charged 201 and the charging box 100 of any one of the preceding embodiments.

Fig. 5 and 6 show the charging box 100 provided with the cover 2, but this should be taken as exemplary and not restrictive, and the charging box 100 may not be provided with the cover 2, and the disclosure is not limited thereto.

The specific embodiments described herein are merely illustrative of the spirit of the disclosure. Those skilled in the art to which the disclosure pertains may make various modifications, additions, or substitutions to the described embodiments without departing from the spirit of the disclosure or exceeding the scope of the appended claims.
