Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 and 2 together, fig. 1 is a schematic structural view illustrating an open state of an embodiment of a charging box provided in the present application, and fig. 2 is an exploded structural view of the charging box in fig. 1. It should be noted that: the direction indicated by the broken-line arrow in fig. 1 can be simply regarded as the direction in which the second housing assembly rotates relative to the first housing assembly when the charging cartridge is switched to the closed state.

In this application, the charging box 10 may be used to store a real wireless earphone (not labeled in the figure), and may also be used to charge the real wireless earphone stored therein. The present embodiment is exemplified by the case that the real wireless headset is placed in the charging box 10 in a "standing" manner (commonly referred to as "standing"). In other words, when the charging box 10 is in the open state, the ear stem portion of the real wireless earphone can be hidden inside the charging box 10, and the ear plug portion can be at least partially exposed outside the charging box 10 for the user to take. Of course, a true wireless headset may also be placed in the charging box 10 in a "lying" manner (colloquially referred to as "lying").

Referring to fig. 1 and 2, the charging cartridge 10 may include a first housing assembly 11, a second housing assembly 12, and a rotation shaft assembly 13. Wherein the second housing assembly 12 is provided to be rotatable with respect to the first housing assembly 11 by the rotation shaft assembly 13 so that the charging box 10 can be switched between a closed state and an open state. Further, the first housing component 11 may be provided with a first accommodating chamber 111, and the second housing component 12 may also be provided with a second accommodating chamber 121. Thus, when the second housing component 12 rotates relative to the first housing component 11 to make the charging box 10 in a covering state, the second accommodating chamber 121 and the first accommodating chamber 111 cooperate to accommodate a real wireless earphone; that is, the first housing member 11 and the second housing member 12 may together surround the real wireless headset, thereby increasing the stability of the charging box 10 for receiving the real wireless headset. Illustratively, the first receptacle 111 may be primarily a handle portion for receiving a real wireless headset, and the second receptacle 121 may be primarily an ear bud portion for receiving a real wireless headset. Therefore, the size, shape and other structural parameters of the first receiving chamber 111 and the second receiving chamber 121 can be reasonably designed according to the external shape structure of the real wireless earphone, and the design is not limited herein.

It should be noted that: with reference to fig. 1, since the real wireless earphones are generally used in pairs, the number of the first accommodating chamber 111 and the second accommodating chamber 121 is correspondingly two, so as to accommodate the real wireless earphones respectively.

Illustratively, the first housing assembly 11 may include a first outer shell 112 and a first inner shell 113. The first inner shell 113 may be assembled and connected with the first outer shell 112 by one or a combination of assembling manners such as glue joint, snap joint, and screw joint. At this time, the first receiving chamber 111 may be disposed in the first inner housing 113, and particularly, located at a side of the first inner housing 113 facing the second housing assembly 12. Further, a receiving cavity (not labeled) with a certain volume may be formed between the first inner housing 113 and the first outer housing 112, and the receiving cavity may be used to dispose structural members such as a main board of the charging box 10, so that the charging box 10 can charge the wireless headset.

Illustratively, the second housing assembly 12 may include a second outer shell 122 and a second inner shell 123. The second inner housing 123 may be assembled and connected to the second outer housing 122 by one or a combination of assembling methods such as glue joint, snap joint, and screw joint. At this time, the second housing bin 121 may be disposed on the second inner shell 123, and particularly, on a side of the second inner shell 123 facing the first shell assembly 11.

It should be noted that: with reference to fig. 1, when the charging box 10 is switched to the closed state, the second housing 122 may be spliced with the first housing 112; the first and second inner casings 113 and 123 are located inside the first and second outer casings 112 and 122. Based on this, the true wireless headset may be mainly co-surrounded by the first inner case 113 and the second inner case 123. Further, the elastic modulus of the second inner case 123 may be less than or equal to that of the first inner case 113. For example: the first inner housing 113 is made of hard plastic, and the second inner housing 123 is made of soft plastic such as silicone rubber or rubber. For another example: the first inner housing 113 and the second inner housing 123 are both made of hard plastic, and the inner surface of the second inner housing 123 is further provided with soft plastic such as silica gel and rubber. So to make the box 10 that charges when being the lid state of closing at second casing subassembly 12 for first casing subassembly 11, second inner shell 123 presses and holds true wireless earphone, both can increase the stability that the box 10 that charges accomodates true wireless earphone like this, can avoid true wireless earphone to be crushed again.

Further, a first magnetic member (not shown) may be disposed in the first housing component 11; accordingly, a second magnetic member (not shown) may be disposed within the second housing component 12. The first magnetic attraction piece and the second magnetic attraction piece can be respectively permanent magnets with different polarities, or one permanent magnet and the other magnetic attraction piece can be a magnetic structure piece such as iron, cobalt, nickel and the like which are easy to magnetize, so that the first magnetic attraction piece and the second magnetic attraction piece can attract each other. Thus, when the charging box 10 is in the closed state, the first housing component 11 and the second housing component 12 can be attracted to each other through the built-in first and second magnetic attraction members, so as to maintain the closed state of the charging box 10, and further increase the reliability of the charging box 10.

Illustratively, the rotating shaft assembly 13 may include a first fitting member 131, a second fitting member 132, and a rotating shaft 133. The rotating shaft 133 can be simultaneously inserted through the first fitting member 131 and the second fitting member 132, so that the first fitting member 131 and the second fitting member 132 can rotate relative to each other. Further, the first fitting member 131 may be assembled and connected with the first housing assembly 11 (specifically, the first inner housing 113), and the second fitting member 132 may be assembled and connected with the second housing assembly 12 (specifically, the second inner housing 123), so that the second housing assembly 12 can rotate relative to the first housing assembly 11 through the rotating shaft assembly 13, and the charging box 10 can be switched between the closed state and the open state.

It should be noted that: the first fitting member 131 may be a part of the first housing assembly 11, for example, the first fitting member 131 and the first inner housing 113 are integrally formed as an injection molding. Similarly, the second fitting member 132 may be a part of the second housing assembly 12, for example, the second fitting member 132 and the second inner housing 123 are integrally formed as an injection molded part.

Referring to fig. 3 to 6 together, fig. 3 is a partial structural schematic view of another embodiment of the charging box provided in the present application, fig. 4 is a side structural schematic view of the charging box in fig. 3 in a closed state, fig. 5 is a side structural schematic view of the charging box in fig. 3 in a critical state, and fig. 6 is a side structural schematic view of the charging box in fig. 3 in an open state. It should be noted that: for convenience of description, the charging box of the present embodiment only illustrates the rotating shaft assembly and the elastic member connected thereto. The first mating member is connected with the first shell assembly and can be used as a part of the structure of the first shell assembly, so that the first mating member can be simply regarded as the first shell assembly. Similarly, since the second mating member is connected to the second housing assembly and can be a part of the structure of the second housing assembly, the second mating member can be simply regarded as the second housing assembly. Further, the process of switching the charging box to the open state may be described in the order of fig. 4 to 6; on the contrary, the process of switching the charging box to the closed state can be described according to the sequence of fig. 6 to 4. When the charging box is in the critical state shown in fig. 5, the elastic member obtains the maximum elastic potential energy correspondingly.

The main differences from the above described embodiment are: in this embodiment, in conjunction with fig. 3, the charging box 10 may further include an elastic member 14. One end of the elastic element 14 may be assembled and connected with the first housing component 11 (specifically, the first fitting element 131), and the other end may be assembled and connected with the second housing component 12 (specifically, the second fitting element 132). Further, the elastic member 14 is configured to be elastically deformed along with the rotation of the second housing assembly 12 relative to the first housing assembly 11. In this way, during the process of switching the charging box 10 to the closed state or the open state, the elastic potential energy of the elastic member 14 can be gradually increased and then gradually decreased. Through the above manner, the technical effects of the embodiment at least include the following aspects:

1) since the second housing component 12 can force the elastic member 14 to elastically deform during the rotation relative to the first housing component 11, the rotation of the second housing component 12 can be accompanied by a certain damping feeling. Furthermore, the rotation of the second housing assembly 12 can become smoother due to the gradual change of the elastic potential energy of the elastic member 14. In other words, when the user opens or closes the charging box 10, the user can not only obtain a certain damping feeling, but also enjoy silkiness, thereby greatly improving the use feeling of the user on the charging box 10.

2) Since the elastic potential energy of the elastic member 14 can be gradually increased and then gradually decreased during the rotation of the second housing assembly 12 relative to the first housing assembly 11, the elastic potential energy released by the elastic member 14 can replace the acting force that needs to be applied subsequently by the user. In other words, after the user finishes opening or closing the first half of the charging box 10, the charging box 10 may automatically finish the remaining second half (colloquially referred to as "automatic opening/closing").

In some embodiments, when the user needs to open (or close) the charging box 10, the user may first rotate the second housing component 12 to a critical state relative to the first housing component 11, and the elastic member 14 is elastically compressed and deformed to gradually accumulate elastic potential energy; thereupon, the second housing component 12 can go beyond the critical state under the opening (or closing) inertia of the user, and the elastic member 14 gradually releases the elastic potential energy, thereby "pushing" the second housing component 12 to continue rotating relative to the first housing component 11 until reaching the opening state (or closing state). Based on this, the elastic member 14 may be in an elastically compressed state during the rotation of the second housing assembly 12, so that the elastic member 14 can obtain enough elastic potential energy, and thus the charging box 10 can be switched to the closed state or the open state. Further, the elastic member 14 may still maintain the elastic compression state after the charging box 10 is switched to the closed state or the open state, so that the elastic member can elastically support the first housing component 11 and the second housing component 12, thereby enabling the charging box 10 to better maintain the closed state or the open state.

In other embodiments, when the user needs to open (or close) the charging box 10, the user can first rotate the second housing component 12 to a critical state relative to the first housing component 11, and the elastic member 14 is elastically deformed to gradually accumulate elastic potential energy; then, the second housing component 12 can go beyond the critical state under the opening (or closing) inertia of the user, and the elastic member 14 gradually releases the elastic potential energy, thereby "pulling" the second housing component 12 to continue rotating relative to the first housing component 11 until reaching the opening state (or closing state). Based on this, the elastic member 14 can be in an elastic extension state during the rotation of the second housing assembly 12, so that the elastic member 14 can obtain enough elastic potential energy, and thus the charging box 10 can be switched to the closed state or the open state. Further, the elastic element 14 can still maintain the elastic stretching state after the charging box 10 is switched to the closed state or the open state, so that the elastic stretching state can elastically pull the first housing component 11 and the second housing component 12, and further the charging box 10 can better maintain the closed state or the open state.

Based on the above detailed description, and with reference to fig. 4 to 6, the present embodiment is exemplarily illustrated that the elastic member 14 is in an elastic compression state at least during the rotation of the second housing component 12.

However, the inventors of the present application found in long-term development: with reference to fig. 4 to 6, the second housing component 12, during the rotation relative to the first housing component 11, will not only force the elastic component 14 to deform elastically, but also rotate at a certain angle relative to the elastic component 14; the resilient member 14 will then rotate at an angle relative to the first housing component 11. It is clear that the elastic element 14, in addition to being required to satisfy the basic requirement of elastic deformation to accumulate or release elastic potential energy, also has to take into account the requirement of relative rotation between it and the first housing component 11 and/or the second housing component 12. It is known that when two structural members are moved in contact with each other, wear occurs to some extent, and the reliability, the service life, and the like thereof are affected thereby. For this reason, the present application further improves the structure of the elastic element 14 and other associated structural members, so as to improve the rotation condition between the elastic element 14 and the first casing assembly 11 and/or the second casing assembly 12, and further enable the elastic element 14 to better withstand the combined condition of elastic deformation and rotation.

Referring to fig. 7 to 9 together, fig. 7 is a schematic structural view of an embodiment of the elastic member in fig. 3, fig. 8 is a schematic structural view of the elastic member in fig. 7 from the top, and fig. 9 is a schematic structural view of the elastic member in fig. 7 from the front.

Referring to fig. 7, the elastic member 14 may include a body portion 141, a first shaft portion 142, and a second shaft portion 143 that are integrally connected. The first and second rotating shaft portions 142 and 143 are disposed at two ends of the main body 141, and are bent with respect to the main body 141. Further, the main body 141 is disposed in a spiral shape and has a central axis 144. In other words, the basic structure of the body portion 141 may be similar to a spring so that the elastic member 14 is elastically deformed to accumulate or release elastic potential energy. Unlike the related art: the first and second rotating shaft portions 142 and 143 are also provided in a rod shape and have first extension components in directions perpendicular to the central axis 144, respectively, so as to be relatively rotatable with the other structural member 100 by means of, for example, shaft hole fitting. Thus, the elastic member 14 can not only bear the composite working condition of elastic deformation and rotation, but also reduce the abrasion of the elastic member 14 in relative rotation with other structural members 100, thereby improving the rotation working condition of the elastic member 14.

For example, referring to fig. 3 and 7, the first shaft portion 142 may be movably connected to the first housing component 11, and the second shaft portion 143 may be movably connected to the second housing component 12. Based on the above description, the first fitting member 131 may be provided with a through-hole or through-hole for engaging with the first rotating shaft portion 142, and the second fitting member 132 may be provided with a through-hole or through-hole for engaging with the second rotating shaft portion 143. Thus, the elastic member 14 can be movably connected to the first mating member 131 and the second mating member 132, respectively. Further, with reference to fig. 4-6, during the rotation of the second housing assembly 12 relative to the first housing assembly 11, the angle of rotation of the second housing assembly 12 relative to the elastic member 14 is generally greater than the angle of rotation of the elastic member 14 relative to the first housing assembly 11. Based on this, the axis of the second rotating shaft portion 143 is further parallel to the axis of the rotating shaft assembly 13 (specifically, the rotating shaft 133), so that the second housing assembly 12 rotates relative to the elastic member 14 during the rotation relative to the first housing assembly 11, and the elastic member 14 is forced to elastically deform following the rotation of the second housing assembly 12. In this way, the abrasion between the elastic member 14 and the second mating member 132 is reduced as much as possible based on the composite condition that the elastic member 14 undergoes elastic deformation and rotation. Of course, the axis of the first rotating shaft portion 142 may be parallel to the axis of the rotating shaft 133 to reduce the wear between the elastic member 14 and the first fitting member 131 as much as possible.

Based on the above detailed description, and with reference to fig. 3 to 7, since the axis of the second rotating shaft portion 143 may be parallel to the axis of the rotating shaft assembly 13 (specifically, the rotating shaft 133), the axis of the first rotating shaft portion 142 and the axis of the rotating shaft assembly 13 may form a reference plane, so that the axis of the second rotating shaft portion 143 may be parallel to the reference plane. The axis of the second rotating shaft 143 will move from one side of the reference plane to the other side during the rotation of the second housing component 12. Further, the elastic member 14 obtains the maximum elastic potential energy when the axis of the second rotating shaft portion 143 is coplanar with the reference plane.

For example, referring to fig. 8, the axis of the first rotating shaft portion 142 may intersect the central axis 144, and the axis of the second rotating shaft portion 143 may also intersect the central axis 144. In this way, the elastic deformation of the elastic member 14 following the rotation of the second housing component 12 is more stable.

Further, the orthographic projection of the first rotating shaft part 142 and/or the second rotating shaft part 143 on the reference projection plane perpendicular to the central axis 144 at least partially falls outside the orthographic projection of the main body part 141 on the reference projection plane, so that the elastic member 14 is assembled and connected with the first fitting member 131 and the second fitting member 132. In this way, the contact area between the first rotating shaft 142 and the first mating member 131 and/or between the second rotating shaft 143 and the second mating member 132 can be increased to some extent, so as to increase the smoothness of the elastic deformation of the elastic member 14 and reduce the wear.

In addition, when the elastic element 14 is assembled and connected with the first mating element 131 and the second mating element 132, referring to fig. 3, the free end of the second rotating shaft 143 departing from the main body 141 can be suspended and not contacted with the second mating element 132, so as to prevent the free end of the second rotating shaft 143 from scratching the second mating element 132 during the rotation of the second housing assembly 12 due to the factors such as the burr of the cross section and the deflection, and reduce the above abrasion. Accordingly, the first spindle portion 142 may also be similarly designed. Of course, referring to fig. 9, since the angle of rotation of the elastic element 14 relative to the first housing assembly 11 is small, and the first rotating shaft portion 142 can be matched with the through slot on the first fitting 131, so that the free end of the first rotating shaft portion 142 away from the main body portion 141 can also be bent toward the direction close to the main body portion 141, and scratches and abrasion caused by end surface burrs, deflection and the like can also be improved.

Exemplarily, referring to fig. 9 and 7, the elastic member 14 may further include a first connection portion 145 connecting the first rotation shaft portion 142 and the body portion 141 and a second connection portion 146 connecting the second rotation shaft portion 143 and the body portion 141. The first connecting portion 145 and the second connecting portion 146 respectively have a second extending component in a direction parallel to the central axis 144, so that the first rotating shaft portion 142 and the main body portion 141 can have a certain distance on the central axis 144, and the second rotating shaft portion 143 and the main body portion 141 can also have a certain distance on the central axis 144, thereby facilitating the assembly and connection of the elastic element 14 and other structural elements 100. Based on this, the axes of the first connecting portion 145 and the second connecting portion 146 may be parallel to the central axis 144, respectively, so as to increase the smoothness of the elastic deformation of the elastic member 14.

Further, at least the first connecting portion 145 of the first connecting portion 145 and the second connecting portion 146 is disposed in an arc shape, so that an external force (a tensile force or a compressive force, etc.) can be sufficiently and effectively transmitted to the main body portion 141, and further, the elastic deformation of the elastic member 14 mainly occurs in the main body portion 141, so as to increase the reliability of the elastic member 14 for accumulating or releasing elastic potential energy, and prolong the service life.

In general, the various structural parameters of the elastic member 14 can be reasonably designed according to the elastic potential energy required to be accumulated or released by the elastic member 14, the allowable installation space, and the like, and are not limited herein. The following description, with reference to fig. 9, illustrates the main structural parameters of the elastic member 14:

1) since the elastic member 14 can be made of a metal wire through a coil spring, bending, and other processes, and the main body 141 is configured like a spring, the wire diameter of the main body 141 can be equal to the diameters of the first rotating shaft 142, the second rotating shaft 143, the first connecting portion 145, the second connecting portion 155, and other portions.

Further, for the main body 141, the outer diameter, the inner diameter, the middle diameter, the pitch, the effective number of turns, the spiral direction and other structural parameters can be reasonably designed with reference to a general spring, and are not limited herein.

2) The arc radius R of the first connection portion 145 may satisfy the relation: a is more than R and less than or equal to b; where a denotes the wire diameter of the body 141 and b denotes the outer diameter of the body 141. Illustratively, R is (0.3-0.7) b. Further, the ratio between b and a may satisfy the relation: b/a is more than or equal to 4 and less than or equal to 10. Thus, the elastic potential energy required to be accumulated or released by the elastic member 14 and the allowable installation space are both satisfied. In addition, the outer diameter of the main body portion 141 may be gradually varied, such as gradually increased or gradually decreased, and then gradually increased and then gradually decreased, or gradually decreased and then gradually increased, on the central axis 144.

Further, the axis of the second rotating shaft portion 143 and the axis of the first rotating shaft portion 142 are parallel to each other, and the axis of the first rotating shaft portion 142 and the central axis 144 form an included angle θ; wherein theta is more than or equal to 45 degrees and less than or equal to 135 degrees. Thus, when the elastic potential energy required to be accumulated or released by the elastic element 14 can meet the requirement of elastic deformation, the main body 141 is obliquely arranged, for example, the central axis 144 is not perpendicular to the axis of the rotating shaft 133, so that the installation space of the elastic element 14 can be further saved, and the miniaturization of the product is facilitated. Furthermore, with reference to fig. 3 and 7, at least the intersecting portion of the second rotating shaft portion 143 and the second connecting portion 146 is prevented from being caught in the second fitting 132, so that the charging box 10 is prevented from being jammed during opening or closing, and the wear is reduced.

Referring to fig. 10 to 14 together, fig. 10 is a schematic structural diagram of an embodiment of an elastic element provided in the present application, fig. 11 is a schematic structural diagram of another embodiment of an elastic element provided in the present application, fig. 12 is a schematic structural diagram of another embodiment of an elastic element provided in the present application, fig. 13 is a schematic structural diagram of still another embodiment of an elastic element provided in the present application, and fig. 14 is a schematic structural diagram of a side view of the elastic element in fig. 12 or fig. 13 applied to a charging box. It should be noted that: for convenience of description, the charging box shown in fig. 14 only illustrates the rotating shaft member and the elastic member connected thereto, and the charging box shown in fig. 14 is in a closed state. Further, the direction indicated by the broken-line arrow in fig. 14 can be simply regarded as the direction in which the second housing assembly rotates relative to the first housing assembly when the charging cartridge is switched to the open state.

Based on the above detailed description, the elastic assembly 20 may include at least two elastic members 14. Wherein, the first rotating shaft part 142 of each elastic element 14 and the first rotating shaft part 142 of the adjacent elastic element 14 extend and are connected with each other; and/or the second rotating shaft part 143 of each elastic member 14 and the second rotating shaft part 143 of the adjacent elastic member 14 extend opposite to each other and are connected. In other words, the elastic members 14 can be reasonably arranged, combined and connected according to actual use requirements to form the elastic assembly 20, so as to meet the use requirements of more complex working conditions.

The following description will exemplarily take an example in which the number of the elastic members 14 is two, and the second rotation shaft portions 143 of the two elastic members 14 extend and are connected to each other. Wherein, the axes of the second rotating shaft parts 143 of the two elastic members 14 may coincide.

In some embodiments, in conjunction with fig. 10 or 11, the central axes 144 of the body portions 141 of the two elastic members 14 are parallel to each other, and the axes of the first rotating shaft portions 142 of the two elastic members 14 may be collinear. The first shaft portions 142 of the two elastic members 14 may extend opposite to each other as shown in fig. 10, or may extend away from each other as shown in fig. 11. Further, the first rotating shaft portions 142 of the two elastic members 14 may also extend opposite to each other and be connected. At this time, referring to fig. 3, when the elastic member 20 is applied to the charging box 10, the principle of the elastic member 20 elastically deformed during the opening or closing of the charging box 10 may be substantially the same as that described in fig. 4 to 6, for example, the two elastic members 14 obtain the maximum elastic potential energy almost simultaneously. As such, by properly designing the consistency of the two elastic members 14, the opening or closing process of the charging box 10 can be more stable, and the damping feeling can be more enhanced.

In other embodiments, referring to fig. 12 or 13, the included angle of the space formed by the central axes 144 of the main body portions 141 of the two elastic members 14 is an acute angle, and the axes of the first rotating shaft portions 142 of the two elastic members 14 may be parallel. The second rotating shaft portions 143 of the two elastic members 14 may extend opposite to each other as shown in fig. 12, or may extend opposite to each other as shown in fig. 13. At this time, referring to fig. 14, when the elastic member 20 is applied to the charging box 10, the principle of the elastic member 20 elastically deformed during the opening or closing of the charging box 10 is not exactly the same as that described in fig. 4 to 6, for example, the two elastic members 14 obtain the maximum elastic potential energy back and forth. Thus, the opening or closing process of the charging box 10 can be more stable and have a damping feeling, and can also have a layered feeling.
