Referring to fig. 1, fig. 2 and fig. 3, the present invention provides a pressure maintaining device 10, which can be applied to an assembling apparatus 100 for assembling a rear shell 300 of an earphone. The pressure maintaining device 10 is configured to abut against a charging pin350 (also referred to as a charging pin) on the earphone rear case 300 for pressure maintaining. Further, referring to fig. 8, the rear earphone housing 300 may be substantially a rectangular structure, two edges of one end of the rear earphone housing may start to form a glue avoiding groove 310, and a supporting pillar 330 is protruded from a bottom wall of the glue avoiding groove 310. At this moment, glue is dispensed in the glue-avoiding groove 310, then the charging pin350 is supported and positioned on the supporting column 330, and the charging pin350 is abutted against the surface deviating from the supporting column 330 by the pressure maintaining device 10, so that the glue is solidified by waiting for dispensing, and the charging pin350 is limited and fixed on the earphone rear shell 300.

In an embodiment of the present invention, please refer to fig. 2 and fig. 3 in combination, the pressure maintaining device 10 includes a driving member 11 and an abutting member 13. Wherein, the abutting member 13 is defined to have two opposite ends, one end of the abutting member 13 is connected to the driving member 11, and the other end is provided with an abutting surface 131 adapted to the charging pin350, when the abutting member 13 is driven by the driving member 11 to move, the abutting surface 131 can abut against the charging pin350.

In an embodiment of the invention, the driver 11 may be used to provide power to drive the abutment 13 to move in a direction facing the headset back housing 300. The driving member 11 may be a cylinder, and the abutting member 13 is connected to the telescopic end of the cylinder. At this time, since the earphone rear case 300, the abutting member 13 and the air cylinder can be sequentially distributed in the moving direction of the abutting member 13, the whole structure is relatively compact, the occupation of the space is reduced, and meanwhile, the mutual interference does not occur, which is beneficial to improving the stability and the safety of the pressure maintaining device 10 in the working process. Of course, the present application is not limited thereto, and in other embodiments, the driving member 11 may also be a linear module, in which case, the abutting member 13 is in transmission connection with a slide of the linear module. That is, it is sufficient to ensure that the driving member 11 can drive the abutting member 13 to move in a direction facing the earphone rear case 300. The contact member 13 may be configured to contact the charging pin350 on the earphone rear case 300 to contact and maintain pressure on the charging pin350. Wherein, the connection of one end of the abutting piece 13 with the driving piece 11 can be understood as: the abutment 13 and the driver 11 have a fixed connection relationship. Of course, this is also understood to be: the abutting member 13 and the driving member 11 are separately disposed and only have an abutting driving relationship (i.e. the driving member 11 abuts against the abutting member 13 and drives the abutting member 13 to move after being activated). The contact surface 131 on the other end of the contact member 13 may be a concave arc surface to be contacted with the surface of the charging pin350 away from the earphone rear case 300. Of course, the abutting surface 131 may be a plane, and may be specifically configured to be adaptive according to the shape of the surface of the charging pin350 away from the earphone rear case 300, so as to ensure that the charging pin350 and the charging pin are abutted in a matching manner, and a uniform abutting force may be applied to the charging pin350.

When the pressure holding device 10 according to the aspect of the present invention is used to hold pressure for abutting against the charging pin350 on the earphone rear case 300, the driver 11 drives the abutting piece 13 to move in a direction facing the earphone rear case 300, and then the abutting surface 131 of the abutting piece 13 can abut against the charging pin350. So make the pin350 that charges can keep spacing fixed relatively before lieing in earphone backshell 300 and the point that charges between the pin350 and solidifying to the completion carries out the butt pressurize to the pin350 that charges on the earphone backshell 300.

In the pressure maintaining device 10 of the present embodiment, the driving of the contact member 13 by the driving member 11 contacts the charging pin350 on the earphone rear case 300, so that the contact force is always parallel to the moving direction of the contact member 13. The contact surface 131 of the contact member 13 is in contact with the charging pin350 in a fitting manner, so that the contact member 13 can be in contact with the charging pin350 uniformly at all places through the contact surface 131. Compare in prior art through artifical manual mode of assembling the pressurize to charging pin350 and be difficult to guarantee to charging pin350 exert comparatively even butt force, make and cause charging pin 350's one side sunken, the convex phenomenon in one side easily, pressurizer 10 in this scheme can exert comparatively even butt force through driving piece 11 and the combination of butt piece 13 and carry out the butt pressurize to charging pin350, avoid causing charging pin 350's one side sunken, the convex phenomenon in one side, thereby improved charging pin 350's equipment effect.

Referring to fig. 2, fig. 3, fig. 4 and fig. 6, in an embodiment of the present invention, the abutting member 13 includes a main rod 133 and a pressure maintaining head 137, and one end of the main rod 133 is connected to the driving member 11; one end of the pressure retaining head 137 is inserted into one end of the main rod 133 away from the driving member 11, and the other end is provided with an abutting surface 131.

It will be appreciated that the abutment member 13 is constituted by the main body rod 133 and the pressure-maintaining head 137, so that both can be separately and independently manufactured first, and then assembled to form a whole after the main body rod 133 and the pressure-maintaining head 137 are each completely molded. The structure of the main body rod 133 and the pressure-maintaining head 137 is simpler than the entire structure of the abutment member 13, which is advantageous for improving the convenience of processing and manufacturing the abutment member 13. Of course, the present application is not limited thereto, and in other embodiments, the main body rod 133 and the pressure maintaining head 137 of the abutment member 13 may be an integral structure. The cross section of the main rod 133 may be circular, square or rectangular, so that the shape is regular and the main rod is easy to machine. Of course, the application is not limited thereto, and in other embodiments, the cross section of the main rod 133 may be triangular, elliptical, or irregular. The pressure maintaining head 137 may have a substantially plate-shaped structure so that it can be stably limited without rotating after being inserted into the main body rod 133. Meanwhile, the shape of the pressure maintaining head 137 is regular, and the processing and the forming are convenient. Of course, the present application is not limited thereto, and in other embodiments, the pressure maintaining head 137 may also be a substantially cylindrical structure, and a corresponding rotation stopping structure may be provided. In addition, in order to facilitate accurate insertion of the pressure maintaining head 137 at a predetermined mounting position on the main body lever 133. A stopper 138 may be provided on a side circumferential surface of the pressure holding head 137, and the stopper 138 abuts against a surface of the main body rod 133 into which the pressure holding head 137 is inserted.

Referring to fig. 7 and 8 in combination, in an embodiment of the present invention, the pressurizer 10 is defined to have an up-down direction, a thickness of the charging pin350 in the up-down direction is H1, and a thickness of the pressure maintaining head 137 in the up-down direction is H2, which satisfy the following relationship: H2/H1 is more than or equal to 2/3 and less than or equal to 3/4.

It can be understood that when the ratio H2/H1 of the thickness of the voltage holding head 137 and the thickness of the charging pin350 is smaller than 2/3, the area of the abutting surface 131 between the voltage holding head 137 and the charging pin350 is relatively small, which may affect the uniformity of the abutting force of the voltage holding head 137 to the charging pin350. When the ratio H2/H1 of the thickness of the pressure maintaining head 137 and the thickness of the charging pin350 is greater than 3/4, the volume of the pressure maintaining head 137 is relatively large and easily interferes with the structure on the earphone rear case 300. Therefore, in order to ensure the uniformity of the abutting force of the pressure holding head 137 on all parts of the charging pin350 and reduce the possibility of interference with the structure on the earphone rear case 300, the ratio H2/H1 of the thickness of the pressure holding head 137 to the thickness of the charging pin350 is set to be 2/3 ≦ H2/H1 ≦ 3/4. The ratio H2/H1 between the thickness of the pressure holding head 137 and the thickness of the charging pin350 may be 2/3, 17/24, or 3/4, or may be any value in the above range.

In an embodiment of the present invention, the pressure maintaining head 137 is made of an anti-static material.

It can be understood that the pressurize head 137 adopts prevents the static material, can avoid the pressurize head 137 to produce static and lead to the fact the influence to charging pin350 when carrying out the butt with charging pin350 to the security that pressurizer 10 carried out the butt pressurize to charging pin350 has been improved. The material of the pressure maintaining head 137 may be an anti-static polyformaldehyde plate, an anti-static acrylic plate, an anti-static polyvinyl chloride plate, or the like.

In one embodiment of the present invention, the pressure maintaining head 137 is detachably connected to the main body rod 133.

It can be understood that the pressure maintaining head 137 is detachably coupled so that it can be detached and lowered from the main body bar 133 for maintenance or replacement when damaged, thereby facilitating the improvement of the convenience of maintenance or replacement of the pressure maintaining head 137. The pressure maintaining head 137 and the main body rod 133 may be connected by a screw, that is, a screw penetrates through a sidewall of the main body rod 133 and is inserted into the pressure maintaining head 137. The screw connection has the advantages of simplicity and reliability, and the connection stability of the pressure maintaining head 137 and the main body rod 133 can be ensured, and meanwhile, the dismounting process of the pressure maintaining head 137 and the main body rod 133 is simplified. Of course, the present application is not limited thereto, and in other embodiments, the pressure maintaining head 137 and the main body rod 133 may be fixed by a snap connection or a magnetic attraction.

Referring to fig. 4 and 7, in an embodiment of the present invention, the pressure maintaining device 10 further includes a fixing base 15, the fixing base 15 is provided with a sliding cavity 151, the sliding cavity 151 extends along a moving direction of the abutting member 13, and the sliding cavity 151 has an opening penetrating through two opposite surfaces of the fixing base 15; one end of the main rod 133, which is far away from the pressure retaining head 137, is slidably inserted into the sliding cavity 151 through an opening of the sliding cavity 151, and is inserted out through another opening of the sliding cavity 151 to be in abutting connection with the driving member 11 for transmission.

It can be understood that the main body rod 133 can be accommodated and supported by the sliding cavity 151 of the fixing seat 15, so that the stability of the installation of the main body rod 133 can be improved. At this time, the end of the main rod 133 away from the pressure retaining head 137 may be disposed separately from the driving member 11, and only have an abutting driving relationship, thereby simplifying the connection between the main rod 133 and the driving member 11. Meanwhile, the sliding cavity 151 can also play a certain guiding role in the movement of the main body rod 133, thereby being beneficial to improving the stability of the movement of the main body rod 133 and facilitating the accurate abutting and pressure maintaining of the main body rod 133 by the pressure maintaining head 137. The cross section of the sliding cavity 151 may be circular, square, or rectangular, and may be specifically configured to be adaptive according to the cross section of the main body rod 133. The slide chamber 151 may be formed in the interior of the holder 15, or may be formed in one surface of the holder 15.

Referring to fig. 4 and 7, in an embodiment of the invention, in a direction in which the fixing base 15 faces the driving element 11, the sliding cavity 151 sequentially includes a first cavity section 153 and a second cavity section 155 that are communicated with each other, an area of a cross section of the second cavity section 155 is larger than an area of a cross section of the first cavity section 153, the pressure maintaining device 10 further includes an elastic element 17, the elastic element 17 is located in the second cavity section 155 and sleeved on the main body rod 133, one end of the main body rod 133, which is away from the pressure maintaining head 137, is sleeved with a limit ring 135, and opposite ends of the elastic element 17 respectively abut against a bottom wall of the second cavity section 155 and the limit ring 135.

In this embodiment, since the two opposite ends of the elastic element 17 abut against the bottom wall of the second cavity 155 and the limiting ring 135, the elastic element 17 can be compressed to generate a deformation elastic force when the main body rod 133 is driven by the driving element 11. When the driver 11 is reset and does not abut against the main rod 133, the elastic member 17 drives the main rod 133 to reset by the deforming elastic force. Thus, the main body rod 133 does not need to be manually reset, thereby improving the convenience of use of the pressurizer 10. The elastic member 17 is sleeved on the main body rod 133, so that the elastic member 17 can be guided by the main body rod 133 to accurately apply an acting force, thereby ensuring that the acting force of the elastic member 17 can be parallel to the moving direction of the main body rod 133. The resilient member 17 may be a spring so that it has a relatively good resilience but has the advantage of a relatively low cost. Of course, the elastic member 17 may also be a plastic member with certain elasticity. The retainer ring 135 may be a snap spring, so that the retainer ring 135 can be directly installed on the main body rod 133 after being purchased in the market without manufacturing. Of course, the limiting ring 135 may also be an additional ring-shaped structure that is sleeved on the main rod 133 and is fixed by gluing or screwed. In addition, in other embodiments, when the elastic element 17 is not provided, an end of the main rod 133 away from the pressure-maintaining head 137 may be directly and fixedly connected to the driving element 11, and the driving element 11 itself drives the main rod 133 to reset in the resetting process.

Referring to fig. 4, in an embodiment of the invention, the surface of the fixing base 15 facing the pressure maintaining head 137 is further provided with a guide rod 157, the guide rod 157 is disposed to extend along the moving direction of the abutting member 13, the pressure maintaining device 10 further includes a rotation stopping block 19, and the rotation stopping block 19 is connected to the main rod 133 and slidably sleeved on the guide rod 157.

It will be appreciated that since the rotation stop 19 is only movable on the guide bar 157 in the direction of extension of the guide bar 157, the abutment 13 is only movable in the direction of the guide bar 157 when driven by the drive member 11. The guide bar 157 guides the movement of the contact member 13, thereby further improving the stability of the movement of the contact member 13. The rotation stopping block 19 can be sleeved on the main rod 133 to increase the contact area between the two to improve the stability of connection between the two. At this time, the screws connecting the main body rod 133 and the pressure holding head 137 may pass through the rotation stopping block 19, so that the three are fixed by the screws at one time, thereby improving the convenience of installation. The cross section of the main rod 133 is circular, and the surface of the main rod 133, which is sleeved and abutted with the pressure maintaining head 137, can be provided with a rotation stopping plane to prevent the main rod and the pressure maintaining head from rotating relatively. In addition, the present invention is not limited to this, and in other embodiments, the rotation stopper 19 may be connected to the side circumferential surface of the main body rod 133, and may be connected by magnetic attraction or snap connection.

Referring to fig. 3 and fig. 5, in an embodiment of the present invention, the number of the abutting members 13 is two, the extending directions of the two abutting members 13 form an included angle, and the first inclined surface 113 is disposed at one end of each of the two abutting members 13 away from the abutting surface 131; the driving member 11 is connected with a pushing block 111, one end of the pushing block 111 far away from the driving member 11 is provided with two second inclined surfaces 113, and one second inclined surface 113 is matched with one first inclined surface 113 for abutting transmission.

Since the charging pins 350 are provided two at two edges of one end of the earphone case, two abutments 13 are provided at this time. Make two pins 350 that charge that can be disposable on the earphone shell through two butt pieces 13 carry out the butt pressurize to be favorable to improving pressurize efficiency. The ends of the main rods 133 of the two abutting members 13 far away from the pressure retaining head 137 are provided with first inclined surfaces 113, and are in abutting fit with the two second inclined surfaces 113 of the pushing block 111 through the two first inclined surfaces 113, so that the two abutting members 13 can be driven to move through one driving member 11. At this time, the setting of one driving member 11 is convenient for guaranteeing the consistency of the magnitude of the driving force to the two abutting members 13, thereby being beneficial to guaranteeing the uniform driving of the two abutting members 13 and improving the uniformity of the abutting of the two abutting members 13 to the two charging pins 350 on the earphone shell. At the same time, one driving member 11 also allows the number of driving members 11 to be reduced, thereby contributing to reduction in manufacturing cost. The abutting piece 13 and the driving piece 11 are in abutting driving through the cooperation of the first inclined surface 113 and the second inclined surface 113, so that the friction force between the two can be reduced, the abrasion is reduced, and the service life of the abutting piece 13 is prolonged.
