Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide the charging box which can improve the uncovering efficiency and is convenient for taking out the earphone.

Referring to fig. 1 to 8, a first embodiment of the charging box of the present invention includes an upper housing 1, a lower housing 5, a middle housing 2, and a reset assembly.

As shown in fig. 1 and 2, the upper case 1 is slidably coupled to the top opening 56 of the lower case 5. Optionally, a handle position 11 is provided on the outer surface of the upper case 1 to facilitate pushing the upper case 1 to open and close the top opening 56.

As shown in fig. 2, the middle shell 2 is disposed in the lower shell 5, and an earphone slot 22 is disposed at the top of the middle shell 2, the earphone slot 22 being used for accommodating the earphone 7, specifically, receiving a TWS earphone. Optionally, the middle shell 2 includes two support structures, namely a middle support 21 and an earphone slot 22, and the earphone slot 22 is fixedly connected above the middle support 21, and can be fixed by screws, buckles, or glue dispensing. Of course, in other embodiments, the middle shell 2 may be a supporting structure, and the earphone slot 22 is directly formed on the upper surface of the middle shell 2.

As shown in fig. 6, the sliding of the upper case 1 on the lower case 5 includes an opening movement in an opening direction K and a closing movement in a closing direction G opposite to the opening direction K. By the upper case 1 moving away from the preset cover closing position and performing the cover opening movement, the top opening 56 is opened, the earphone slot 22 is exposed, the earphone can be taken and placed, and the upper case 1 can move to the preset limit cover opening position along the cover opening direction K farthest, for example, as shown in fig. 8. The top opening 56 is gradually closed by the closing movement of the upper case 1, and when moved to a preset closing position, the top opening 56 is completely covered by the upper case 1, the earphone slot 22 is covered by the upper case 1, and the charging box is brought into a closed state as shown in fig. 6.

The middle case 2 is rotatably coupled to the lower case 5. The rotation center line of the middle shell 2 is perpendicular to the uncovering direction K, in other embodiments, the rotation center line of the middle shell 2 may not be completely perpendicular to the uncovering direction K, and an included angle close to 90 degrees exists between the two directions. Alternatively, as shown in fig. 5 and 6, a shaft fixing portion 58 is fixedly provided in the lower case 5, the rotating shaft 54 is provided on the shaft fixing portion 58, the middle case 2 is rotatably connected to the rotating shaft 54, and the rotation center line of the middle case 2 is the center line of the rotating shaft 54.

The reset assembly is arranged on the lower shell 5. As shown in fig. 7, after the upper shell 1 moves to the preset first reference position along the uncovering direction K, the upper shell 1 continues to be uncovered to the preset limit uncovering position under the driving of the reset assembly, and the middle shell 2 rotates along the lifting direction until at least part of the structure thereof protrudes upwards out of the top opening 56. That is, the preset first reference position and the preset limit opening position are two different positions in the movement process of the upper case 1, and in this embodiment, the preset first reference position is one position between the preset closing position and the preset limit opening position. In addition, the reset assembly may directly drive the upper case 1 and/or the middle case 2, or the reset assembly may drive the upper case 1 and/or the middle case 2 through a transmission structure.

In this embodiment, in the in-process of uncapping, after upper shell 1 uncaps and moves to predetermineeing first reference position, reset assembly provides drive power, make the user need not to apply external force to upper shell 1 again, upper shell 1 and mesochite 2 can carry out the motion of original direction automatically under reset assembly's drive, improve the degree of automation and the efficiency of uncapping, simultaneously, because uncap make earphone 7 stretch out 5 certain distances of inferior valve, can make things convenient for taking out of earphone 7.

Further, as shown in fig. 6 to 8, a linkage structure is provided between the upper case 1 and the middle case 2. When the upper shell 1 moves between the preset second reference position and the preset limit uncovering position, the reset assembly drives the upper shell 1 to move along the uncovering direction K, the linkage structure plays a role in linkage, and the upper shell 1 drives the middle shell 2 to rotate through the linkage structure. At this time, the reset assembly can directly drive the upper shell 1, the upper shell 1 and the linkage structure form a transmission structure, and the reset assembly can drive the middle shell 2 through the transmission structure.

It should be noted that, in the process of the cover opening movement of the upper shell 1, the linkage structure can play a linkage role only when the upper shell 1 moves to the preset second reference position, so as to drive the middle shell 2 to rotate, and before that, the upper shell 1 and the middle shell 2 move respectively without interference; alternatively, the linkage is performed before the upper case 1 is moved to the preset second reference position.

The preset second reference position and the preset limit cover opening position are two different positions of the upper shell 1 in the moving process. In addition, the preset second reference position is the same as the preset first reference position. In other embodiments, the preset second reference position may be different from the preset first reference position, for example, the preset first reference position is located in front of the preset second reference position along the uncovering direction K.

In the embodiment, through the arrangement of the linkage structure, the motion simultaneity of the upper shell 1 and the middle shell 2 can be improved, and the cover opening speed is further ensured; meanwhile, the arrangement of the reset component is facilitated to be simplified, and when only one of the upper shell 1 and the middle shell 2 is directly driven by the reset component, the other can be driven.

Further, as shown in fig. 6 to 8, the linkage structure includes an upper shell push rod 16 fixed to the upper shell 1 and a middle shell slide rail 23 fixed to the middle shell 2. When the upper shell 1 moves from the preset second reference position to the preset limit uncovering position, the upper shell push rod 16 presses the middle shell slide rail 23 to drive the middle shell 2 to rotate along the lifting direction.

In this embodiment, the linkage structure is set as the upper shell push rod 16 and the middle shell slide rail 23, and the processing is convenient. During the opening movement of the upper shell 1, as shown in fig. 7, the upper shell push rod 16 pushes the middle shell slide rail 23, so as to drive the middle shell 2 to rotate.

Further, as shown in fig. 6, the middle shell slide rail 23 includes a front blocking wall 232 and a rear blocking wall 231 which are sequentially arranged in the door opening direction K. When the upper shell 1 is in the predetermined closing position for closing the top opening 56, the bottom end of the upper shell push rod 16 is higher than the top end of the front wall 232 and lower than the top end of the rear wall 231.

As shown in fig. 7, when the upper case 1 moves to the preset second reference position along the lid opening direction K, the upper case push rod 16 abuts against the rear blocking wall 231, and moves along with the upper case 1, as shown in fig. 8, the upper case push rod 16 gradually extends into the gap between the rear blocking wall 231 and the front blocking wall 232 until the front blocking wall 232 presses the upper case push rod 16, and at this time, the middle case 2 is prevented from continuing to rotate by abutting against the upper case push rod 16 through the front blocking wall 232, so as to perform a limiting function. In addition, during the closing process of the upper shell 1, the front blocking wall 232 pressed on the upper shell can be pushed reversely by the upper shell push rod 16 to drive the middle shell 2 to reset along the reverse direction of the lifting direction, so that the middle shell 2 can be pushed bidirectionally by the cooperation of the upper shell push rod 16 and the middle shell slide rail 23.

Of course, in other embodiments, the middle shell sliding rail 23 may also only include the above rear blocking wall 231, and accordingly, the middle shell 2 may be reset and rotated by gravity during the closing movement of the upper shell 1 through the arrangement of the position of the center of gravity of the middle shell 2 and the position of the rotation center line.

Further, after the upper case 1 moves to the predetermined third reference position along the cover closing direction G, the upper case 1 continues to move to the predetermined cover closing position for closing the top opening 56 by the driving of the reset component.

In the lid opening direction K, the preset first reference position is located in front of the preset third reference position, or the preset first reference position and the preset third reference position are the same, in this embodiment, the preset first reference position is the same as the preset third reference position, that is, in the lid closing process, the upper shell 1 just passes through the preset first reference position, and the lid can be automatically and continuously closed under the driving of the reset assembly.

Through the setting of this embodiment, reset assembly can also realize closing the lid automatically except can realizing uncapping automatically, further makes things convenient for the use of box that charges. In addition, the reset assembly provides driving force in different regions, and the driving force in the opposite direction is provided in the front of the preset first reference position and in the back of the preset third reference position in the uncovering direction K, so that the upper shell 1 has the movement trends in the opposite direction, and the driving reliability can be ensured.

Further, after the upper case 1 moves to the preset fourth reference position along the cover closing direction G, the middle case 2 rotates along the direction opposite to the lifting direction under the driving of the reset component and/or the driving of the upper case 1. And in the uncovering direction K, the preset fourth reference position is positioned in front of the preset cover closing position. In this embodiment, the preset fourth reference position is the same as the preset limit uncovering position, so that when the upper shell 1 starts to close the cover, the middle shell 2 is driven to automatically reset and rotate through the linkage structure.

Through the setting in this embodiment, the rotation that resets of mesochite 2 also can the automation go on, further improves the convenience of using.

Further, as shown in fig. 4 and 5, the restoring assembly includes an upper shell elastic member 6, the lower shell 5 is fixedly connected to the supporting block 52 and slidably connected to the upper shell slider 53, and the upper shell elastic member 6 is connected between the upper shell slider 53 and the supporting block 52.

Wherein, set up the slide 131 of uncapping that inclines for uncapping direction K on the epitheca 1, epitheca slider 53 sliding connection is in slide 131 of uncapping. When the upper case 1 is between the preset first reference position and the preset limit uncapping position, the upper case elastic member 6 moves to return, and the upper case slider 53 presses the uncapping slide 131 in the uncapping direction K.

Because the cover opening slide way 131 is an inclined slide way, in the process of the cover opening movement of the upper shell 1, the deformed upper shell elastic piece 6 drives the upper shell slide block 53 to press the cover opening slide way 131, so that the elastic force of the elastic piece is utilized to provide driving force for the cover opening of the upper shell 1.

Further, as shown in fig. 4 and 5, the upper case 1 is further provided with a closing cover slide rail 132 inclined with respect to the door opening direction K, and the upper case slider 53 is slidably connected to the closing cover slide rail 132. When the upper case 1 moves to between the preset fifth reference position and the preset closing position for closing the top opening 56, the upper case elastic member 6 moves to return, and the upper case slider 53 presses the closing slide 132 in the closing direction G. In the uncapping direction K, the preset first reference position is located in front of the preset fifth reference position, or the preset first reference position and the preset fifth reference position are the same. That is, the upper case elastic member 6 can provide a driving force to the upper case 1 during the opening of the cover, in addition to the driving force during the closing of the cover.

More specifically, as shown in fig. 4, a control slide is disposed on the bottom surface of the upper case 1, and the control slide sequentially includes an open-cover slide 131 and a close-cover slide 132 along an open-cover direction K, the open-cover slide 131 is butted with the close-cover slide 132, and the butting point is B.

After the upper shell slide 53 enters the lid opening slide 131 through the point B, the reset force of the upper shell elastic member 6 presses the upper shell slide 53, so that the upper shell slide 53 generates a pressure F1 on the lid opening slide 131, and the pressure F1 has a component force F11 along the lid opening direction K, so that the upper lid 12 is driven by the elastic force of the upper shell elastic member 6 to automatically perform the lid opening movement until the end point C of the lid opening slide 131 moves to be in contact with the upper shell slide 53.

Similarly, when the upper shell slide 53 enters the closing slide 132 through point B, the resetting force of the upper shell elastic element 6 presses the upper shell slide 53, so that the upper shell slide 53 generates a pressure F2 to the closing slide 132, and the pressure F2 has a component force F21 along the closing direction G, so that the upper shell 12 is automatically driven to perform the closing movement by the elastic force of the upper shell elastic element 6 until the end point a of the closing slide 132 moves to be in contact with the upper shell slide 53.

Of course, in other embodiments, only one of the lid opening slide 131 and the lid closing slide 132 may be provided on the upper case 1, for example, in the control slide, only the lid opening slide 131 is provided, and the position of the lid closing slide 132 is changed to a straight slide parallel to the lid opening direction K, so that the upper case slider 53 can not obstruct the movement of the upper case 1, and at the same time, does not provide the driving force in the lid opening direction K or the lid closing direction G.

The control slide is a sliding groove structure disposed on the upper case 1, and accordingly, the upper case slider 53 is slidably inserted into the control slide. More specifically, as shown in fig. 3 and 4, the upper casing 1 includes an upper cover 12 and an upper inner cover 13 fixed to the lower side of the upper cover 12, specifically by means of dispensing. The control slide way penetrates through the upper inner cover 13 along the vertical direction. Of course, in other embodiments, the control slide may also be a raised structure, and correspondingly, the upper shell slide 53 is a slot-like structure slidably fastened to the control slide.

Preferably, as shown in fig. 4, two control slides are symmetrically disposed on the upper case 1, and correspondingly, each control slide is correspondingly disposed with the upper case slider 53. Wherein, one end of the two upper shell elastic pieces 6 can be connected to the same supporting block 52, optionally, the two upper shell elastic pieces 6 are fixed as an integral structure, and the upper shell elastic pieces 6 are fixedly connected to the upper shell sliding block 53 through glue, or are integrally molded. Optionally, the upper shell slide 53 is an injection molded structure.

More specifically, as shown in fig. 5, a main support 51 is fixedly provided in the lower case 5, specifically, fixed with screws. The support block 52 is fixed on the top of the main bracket 51, specifically by screws. Wherein, the support block 52 is fixed at the middle part to the main bracket 51, and a gap is formed between the side pressing plates 532 at both sides and the main bracket 51, and the upper shell elastic member 6 can move in the gap space.

In addition, a sliding support portion 531 is fixedly arranged at the top of the support block 52, accordingly, a limit slide rail 15 extending along the uncovering direction K is arranged on the upper shell 1, the sliding support portion 531 and the support block 52 clamp the edge of the limit slide rail 15 along the up-down direction to limit the upper shell 1 along the up-down direction, and meanwhile, the support block 52 and the limit slide rail 15 can relatively slide along the uncovering direction K, so that the sliding direction and the stroke of the upper shell 1 are limited by the support block 52, and the movement stability of the upper shell 1 is improved. Preferably, the control slide is provided with a lubricant 151 made of teflon sheet, and the lubricant is adhered to the surface of the limit slide 15 by double-sided adhesive, so as to reduce friction between the slide support portion 531 and the limit slide 15 during sliding and improve the smoothness of sliding of the upper cover 12.

In addition, as shown in fig. 3 and 4, a through hole installation part 152 is provided at an end of the limit slide 15, and the sliding support part 531 can pass through the through hole installation part 152 in the vertical direction to realize the installation of the sliding support part 531 on the upper shell 1, after the installation, the installation block 14 can be detachably and fixedly connected to the through hole installation part 152 to block the through hole installation part 152, so as to prevent the sliding support part 531 from separating from the limit slide 15 through the through hole installation part 152. In addition, the mounting block 14 forms a stop for limiting one end of the slide rail 15, and when the upper shell 1 slides to the position where the supporting block 52 abuts against the mounting block 14, the upper shell 1 moves to the end position in one direction.

As shown in fig. 5, the upper shell elastic member 6 includes a spring ring 61, and in other embodiments, the upper shell elastic member 6 may also be a compression spring.

The main support 51 may also provide a protective function, besides providing support for the support block 52 and the upper shell 1. As shown in fig. 5, the main support 51 encloses a mounting cavity with the inner wall of the lower case 5, in which the circuit board 4 and the battery 3 are mounted, protected by the main support 51. Specifically, the battery 3 is fixed to the bottom of the lower case 5 with a double-sided tape, and the circuit board 4 is fixed to the lower case 5 with screws. Meanwhile, the middle shell 2 is located outside the installation cavity, the main support 51 is provided with a rotary stop 57, and after the middle shell 2 is reset, the middle shell 2 is lapped on the rotary stop 57, so that the stability of the middle shell 2 placed in the lower shell 5 is improved.

Wherein, preferably, a spacing rib 55 is connected between the bracket and the lower shell 5 to enhance the stability of the bracket.

Further, the reset component also comprises a magnetic attraction component. The magnetic attraction component is arranged between the lower shell 5 and the middle shell 2. When the upper shell 1 is located between the preset first reference position and the preset limit uncovering position, the magnetic suction assembly has thrust rotating along the lifting direction to the middle shell 2.

In addition, when the upper shell 1 moves to a position between the preset sixth reference position and the preset closing position for closing the top opening 56 along the closing direction G, the magnetic attraction component has a driving force for rotating the middle shell 2 along the direction opposite to the lifting direction. In this embodiment, the preset sixth reference position is the same as the preset first reference position, and in other embodiments, the preset sixth reference position may also be the same as the preset limit uncovering position. That is to say, in this embodiment, during the lid closing movement, before the upper shell 1 moves to the preset first reference position, the upper shell 1 may drive the middle shell 2 to reset by means of the linkage structure, and after the upper shell 1 moves to the preset first reference position, the middle shell 2 continues to reset and rotate under the driving of the reset assembly.

Wherein, specifically, magnetism subassembly is inhaled including uncapping magnetism structure and closed lid magnetism structure of inhaling. As shown in fig. 5 and 6, the uncovering magnetic attraction structure comprises a first magnetic attraction piece 81 fixed on the inner wall of the lower shell 5 and a second magnetic attraction piece 82 fixed on the outer wall of the middle shell 2, the magnetic attraction force is gradually increased along with the approaching of the first magnetic attraction piece and the second magnetic attraction piece, and the middle shell 2 generates a driving force so that the middle shell 2 can automatically move along the lifting direction towards the outer side of the top opening 56 of the lower shell 5.

The charging box that this embodiment provided, the theory of operation is as follows:

after assembly, in the closed position as shown in fig. 4 and 6, the upper shell spring 6 is compressed to some extent in the control track, the upper shell slider 53 is at point a, and the upper shell spring 6 has an outward spreading force according to the slope direction of the segment AB of the control track, so that the upper shell 1 has a force and a tendency to remain closed. The third magnetic attracting element 83 and the fourth magnetic attracting element 84 contact and attract each other to keep the middle shell 2 at the bottom of the lower shell 5.

When the upper case 1 is opened: the upper case 1 is pushed by hand in the lid opening direction K, and the upper inner lid 13 slides on the slide support portion 531. At this time, the upper shell slider 53 moves from a to B, and forces the upper shell elastic member 6 to be further elastically deformed by the force accumulation. As shown in fig. 7, when the upper shell slider 53 reaches point B, the upper shell elastic member 6 reaches the maximum power accumulation, and at this time, the upper shell push rod 16 contacts the rear stopper wall 231. The upper shell 1 is continuously pushed by hand, the push rod 16 of the upper shell pushes the rear blocking wall 231, so that the middle shell 2 rotates and lifts around the rotating shaft 54, and the third magnetic attracting element 83 is separated from the fourth magnetic attracting element 84. As shown in fig. 4 and 8, the upper shell sliding block 53 moves from B to C, and according to the inclination direction of the segment BC of the control track, the upper shell elastic member 6 is unfolded outwards, and the upper shell 1 is opened automatically, that is, in essence, after the upper shell sliding block 53 enters the segment BC, the hand is released, and the upper shell 1 and the middle shell 2 can automatically continue to move; the supporting block 52 contacts and stops with the mounting block 14 at one end of the limiting slide rail 15, and the upper shell 1 keeps an open state. Mesochite 2 only stops the position with rotatory position 57 contact, and at this moment, first magnetism is inhaled piece 81 and second magnetism and is inhaled piece 82 and be close to inter attraction, keeps the lifting state of mesochite 2, conveniently gets and puts earphone 7.

When closing the upper case 1: the upper case 1 is pushed by hand in the closing direction G, and the upper inner lid 13 slides on the slide support 531. At this time, the upper shell slider 53 moves from C to B, and forces the upper shell elastic member 6 to be further elastically deformed by the force accumulation. In the process, the push rod 16 of the upper shell pushes the front blocking wall 232, so that the middle shell 2 rotates around the rotating shaft 54 to fall back, and the first magnetic attracting element 81 and the second magnetic attracting element 82 are separated. When point B is reached, the upper shell elastic member 6 reaches the maximum value of the stored force; the upper shell sliding block 53 moves from B to A, the upper shell elastic part 6 stretches outwards according to the inclination direction of the BA section of the control track, and the upper shell 1 is automatically closed; the supporting block 52 contacts with the other end of the limit slide rail 15 to stop, and the upper shell 1 keeps a closed state. At this time, the third magnetic attracting member 83 and the fourth magnetic attracting member 84 approach each other to attract each other, and the TWS headset 7 is stored conveniently while keeping the sinking state of the middle case 2.

In the charging box provided by the embodiment, the upper shell 1 is a sliding cover type cover opening and closing cover; the upper shell 1 is opened to a certain distance in a sliding mode, the upper shell 1 can be automatically opened and can keep the opening trend, in the process, the middle shell 2 bearing the earphones 7 rotates, the earphones 7 are supported out of the box, and the taking and the placing are convenient. Similarly, the upper shell 1 is slid to close the cover to a certain distance, the upper shell 1 can be automatically closed, the trend of closing is kept, in the process, the middle shell 2 bearing the earphone 7 rotates, the earphone 7 is stored in the box, and the automation degree of the cover opening and closing process is higher.

Obviously, in other embodiments, the preset first reference position may be disposed at other positions. In the second embodiment, the preset first reference position is a preset closing position where the upper case 1 and the lower case 5 are snap-coupled. After the buckle is unfastened, the reset component starts to drive the upper shell 1 to be automatically opened. In addition, no linkage structure may be provided between the upper case 1 and the middle case 2. At this moment, the subassembly that resets includes the first elastic component that sets up between epitheca 1 and inferior valve 5 and the second elastic component of setting between mesochite 2 and inferior valve 5, when the buckle lock, first elastic component and second elastic component all are in the deformation state, the spacing first elastic component of avoiding of buckle drives epitheca 1 and resets, mesochite 2 is pushed down and is prevented the second elastic component and reset by epitheca 1, when untiing the buckle, first elastic component reset motion drives epitheca 1 and opens, and simultaneously, second elastic component reset motion drives mesochite 2 and rotates.

In addition, for the embodiment that the resetting component already includes the structure that the upper shell elastic member 6 provides the driving force, and the linkage structure is provided, as in the third embodiment, the magnetic attraction component is further provided, but the position that provides the magnetic force is different from the first embodiment. The in-process of uncapping, at last shell 1 through predetermine the benchmark position and move one and be greater than 0 apart from the back, magnetism inhale the subassembly and provide magnetic attraction again to mesochite 2, specifically can rotate to providing magnetic attraction again when being close the terminal point at mesochite 2, and the same reason is covered when moving to the closed for magnetism inhale the more main effect of subassembly and lie in locking mesochite 2 at its pivoted extreme position, improve the stability that mesochite 2 placed.

In addition, in the fourth embodiment, the magnetic attraction assembly provided therein only includes one of the open-cover magnetic attraction assembly and the close-cover magnetic attraction assembly of the first embodiment.

In addition, in the first embodiment, the upper shell elastic member 6 is eliminated, and the middle shell 2 automatically rotates and the upper shell 1 automatically moves only by the driving force of the magnetic attraction component between the middle shell 2 and the lower shell 5 through the linkage structure.
