In order to facilitate understanding of the present invention, the principle of pressure maintaining of the earphone will be described herein with reference to the structure of the earphone module. Referring to fig. 9 to 11, the earphone module 500 includes an upper module 510 and a lower module 520, and the upper module 510 and the lower module 520 are detachably connected by a pin 530. Wherein, an upper cavity is arranged in the upper module 510; the lower module 520 is provided with a lower cavity, and the lower cavity and the upper cavity cooperate to form an earphone profiling cavity 501 for accommodating the earphone 600.
Referring to fig. 1 and 11, when the pressure of the earphone 600 is maintained, the earphone 600 after dispensing is firstly placed in the earphone profiling cavity 501 of the earphone module 500; then, the earphone module 500 is placed in the earphone pressure maintaining mechanism, the upper module 510 of the earphone module 500 is pressed by the earphone pressure maintaining mechanism, and after the earphone module is kept still for a period of time (for example, after 8 minutes), the dispensing on the earphone 600 is solidified, and the earphone 600 can be taken out to complete pressure maintaining on the earphone 600.
The present invention provides an embodiment of a headset dwell mechanism that may be applied to dwell a headset 600. The earphone pressure maintaining mechanism can improve the precision of the earphone pressure maintaining mechanism, so that the earphone pressure maintaining mechanism can stably maintain to apply pressure to the earphone.
Referring to fig. 1 to 3, in an embodiment of the headset pressure maintaining mechanism of the present invention, the headset pressure maintaining mechanism includes a base 100, a pressing component 200 and a switching component 300. Wherein the base 100 is provided with a pressure maintaining station 111; the pressing assembly 200 is mounted on the base 100 and is located above the dwell station 111. The pressing assembly 200 is movable up and down with respect to the base 100, and has a working position close to the pressure maintaining station 111 and a waiting position far from the pressure maintaining station 111. The switching assembly 300 is mounted on the base 100, and the switching assembly 300 includes a transmission shaft 310 and an eccentric 320; one end of the transmission shaft 310 is fixedly connected with the pressurizing assembly 200; the eccentric wheel 320 is rotatably connected with the other end of the transmission shaft 310, and the eccentric wheel 320 can drive the transmission shaft 310 to move up and down when in transmission, so that the pressurizing assembly 200 can switch positions.
Specifically, the base 100 may be provided with two or more dwell stations 111; for example, if the base 100 is provided with two dwell stations 111, the two dwell stations 111 may be arranged along the width direction of the base 100 or along the length direction of the base 100; if the base 100 is provided with more than two pressure maintaining stations 111, the more than two pressure maintaining stations 111 may be arranged in the same direction or may be arranged along the same circumferential area, and is not particularly limited.
It is understood that the number of the pressurizing assemblies 200 should be the same as the number of the pressure maintaining stations 111 on the base 100, so that the pressurizing assemblies 200 are in one-to-one correspondence with the pressure maintaining stations 111. Each pressing assembly 200 is movable in an up-down direction relative to the base 100, and has an operating position close to the pressure maintaining position and a waiting position far from the pressure maintaining position.
For the switching elements, the number of the switching elements 300 may be identical to the number of the pressurizing elements 200, so that the switching elements 300 are connected to the pressurizing elements 200 in a one-to-one correspondence, so that one switching element 300 drives one pressurizing element 200 to independently move to switch positions, and thus each pressurizing element 200 can independently pressurize. When one of the pressurizing assemblies 200 fails, the remaining pressurizing devices can be used for pressure maintaining operation, so that the applicability of the earphone pressure maintaining mechanism can be improved. Of course, in other embodiments, the plurality of pressing assemblies 200 may be connected by a linkage, and the linkage is connected to one switching assembly 300, so that one switching assembly 300 may simultaneously drive the plurality of pressing assemblies 200 to move to switch positions. The following description will mainly take one switching unit 300 and one pressurizing unit 200 as examples.
The transmission shaft 310 of the switching assembly 300 is movably installed on the base 100 in the up-down direction, the lower end of the transmission shaft 310 is fixedly connected with the pressurizing assembly 200, and the upper end of the transmission shaft 310 is rotatably connected with the eccentric wheel 320 through the pin 321. The periphery of the eccentric 320 has a proximal portion nearest the center of rotation of the eccentric 320 and a distal portion furthest from the center of rotation. Eccentric 320 has an initial state (not shown) in which it rotates to its center-down position against base 100 (e.g., top plate 130 of base 100), and an operating state (e.g., fig. 3 and 4) in which its center-down position. The eccentric 320 is switchable between the initial state and the operating state by rotation.
When the eccentric 320 of the switching assembly 300 is rotated to the initial state, the eccentric 320 lifts the pressing assembly 200 upward so that the pressing assembly 200 is in the standby position (as shown in fig. 3 and 4). After the earphone cavity module 500 with the earphone 600 is placed in the pressure maintaining station 111 of the earphone pressure maintaining module, the eccentric wheel 320 is rotated 180 degrees, so that the eccentric wheel 320 is switched from an initial state to a working state; during this process, the eccentric 320 releases the drive shaft 310 downward, the drive shaft 310 moves downward, and the compression assembly 200 slides downward accordingly; until the pressurizing assembly 200 contacts the earphone cavity module 500 on the pressure maintaining station 111, the pressurizing assembly 200 presses the upper module 510 of the earphone cavity module 500, so that the earphone 600 in the earphone cavity module 500 can be pressure-maintained.
After the dwell is finished, the eccentric wheel 320 is rotated again by 180 °, so that the eccentric wheel 320 is switched from the operating state to the initial state; in this process, the eccentric 320 pulls the driving shaft 310 upward relatively, so that the driving shaft 310 drives the pressing assembly 200 to slide upward to the standby position, and the pressing assembly 200 releases the earphone cavity module 500. At this time, the earphone cavity module 500 having undergone pressure maintaining may be taken out from the pressure maintaining station 111.
According to the technical scheme, the switching assembly 300 is connected with the pressurizing assembly 200 by installing the switching assembly 300 on the base 100, and the switching assembly 300 comprises a transmission shaft 310 and an eccentric wheel 320; one end of the transmission shaft 310 is fixedly connected with the pressurizing assembly 200; the eccentric wheel 320 is rotatably connected to the other end of the transmission shaft 310, and the eccentric wheel 320 can drive the transmission shaft 310 to move up and down when in transmission, so that the pressurizing assembly 200 is switched between the working position and the waiting position (see the description above). Because the switching device adopts the rotation of the eccentric wheel 320 to switch the position of the pressurizing assembly 200, and the eccentric wheel 320 has a relatively precise tolerance, the pressurizing assembly 200 can be precisely positioned at the working position, the pressurizing assembly 200 can be ensured to stably keep pressing the earphone module, and the precision of the earphone pressure maintaining mechanism is effectively improved.
Referring to fig. 1 to 4, in one embodiment, the base 100 includes a bottom plate 110 provided with a pressure maintaining station 111, a mounting bracket 120 provided on the bottom plate 110 for mounting the pressurizing assembly 200, and a top plate 130 mounted on the mounting bracket 120; wherein the switching assembly 300 is mounted on the top plate 130.
Specifically, the eccentric 320 is mounted on the upper plate surface of the top plate 130; the driving shaft 310 is movably inserted in the top plate 130 in the up-down direction, the upper end of the driving shaft 310 is rotatably connected with the eccentric wheel 320, and the lower end of the driving shaft 310 is fixedly connected with the pressurizing assembly 200. In the initial state, the eccentric 320 has its eccentric portion facing downward against the upper surface of the top plate 130, so that the eccentric 320 keeps lifting the pressing assembly 200 upward. When the eccentric wheel 320 rotates 180 °, the eccentric wheel 320 is switched to an operating state, at this time, the proximal portion of the eccentric wheel 320 is pressed downward against the upper plate surface of the top plate 130 (as shown in fig. 3 and 4), and the eccentric wheel 320 releases the transmission shaft 310.
Further, the switching assembly 300 further comprises a switching handle 330, wherein the switching handle 330 is connected to the eccentric 320, and the switching handle 330 is adapted to be held by a user. In this way, the user can manually drive the eccentric 320 to rotate by holding the switching handle 330, which is simple and easy to operate. Of course, in other embodiments, a motor assembly may be configured and coupled to the eccentric 320 such that the eccentric 320 may be driven to rotate by the motor assembly without requiring manual operation by a user.
Referring to fig. 1 to 4, for the pressing assembly 200, the pressing assembly 200 may be configured in various manners. In one embodiment, the pressing assembly 200 includes a sliding plate 210 and a pressing plate 220; wherein, the sliding plate 210 is slidably installed on the mounting bracket 120 in the up-down direction; the pressing plate 220 is mounted on an outer plate surface of the sliding plate 210 facing away from the mounting bracket 120, and the pressing plate 220 is located above the pressure maintaining station 111 so as to press the earphone module 500 through the pressing plate 220.
Specifically, the slide plate 210 is disposed opposite to the bracket riser 121 of the mounting bracket 120; the inner plate surface of the sliding plate 210 is slidably connected with the mounting bracket 120, so that the sliding plate 210 has a larger sliding surface, and the stability of the pressurizing assembly 200 along the up-and-down movement is improved. The plate surface of the pressurizing plate 220 and the plate surface of the sliding plate 210 are vertically arranged, and the pressurizing plate 220 is opposite to the pressure maintaining station 111 along the up-down direction. The pressing assembly 200 slides up and down through the sliding plate 210, and can drive the pressing plate 220 to relatively approach or separate from the pressure maintaining station 111, so that the earphone module 500 is pressed by the pressing plate 220.
Referring to fig. 5 to 7, for the manner in which the sliding plate 210 is slidably mounted to the mounting bracket 120 in the up-down direction, at least two sliding blocks 211 may be optionally provided on an inner plate surface of the sliding plate 210 facing the mounting bracket 120; the mounting bracket 120 is provided with at least one pair of slide rails 123 extending in the up-down direction, and the slide rails 123 are slidably engaged with the slider 211 (as shown in fig. 8).
Specifically, both plate surfaces of the bracket riser 121 of the mounting bracket 120 are provided with a pair of slide rails 123 extending in the up-down direction; the sliding plate 210 of each pressing assembly 200 is provided with a plurality of sliding blocks 211, and the sliding blocks 211 are fixedly connected with the sliding plate 210, for example, the sliding blocks are fixedly connected with each other by screws. Of the plurality of sliding blocks 211 of the sliding plate 210, a part of the sliding blocks 211 are in sliding fit with one of the sliding rails 123 on one plate surface of the bracket vertical plate 121, and the rest of the sliding blocks 211 are in sliding fit with the other sliding rail 123 on the same plate surface of the bracket vertical plate 121. In this manner, the sliding plate 210 of the pressing assembly 200 can be slidably mounted on the dual rail.
Compared with the traditional earphone pressure maintaining mechanism, the pressurizing assembly 200 of the traditional earphone pressure maintaining mechanism is sleeved on one sliding column through the bearing, and the pressurizing assembly 200 of the traditional earphone pressure maintaining mechanism can have higher parallelism and flatness in the mode that the sliding plate 210 is arranged on the double tracks, so that the pressurizing assembly 200 slides more stably. Of course, in other embodiments, a sliding groove may be directly provided on the inner surface of the sliding plate 210, and the sliding groove may be slidably engaged with the sliding rail 123 on the mounting bracket 120.
As for the connection manner of the pressing plate 220 and the sliding plate 210, there are various connection fixing manners. For example, but not limited to, a slot 212 is provided on the sliding plate 210; one end of the pressing plate 220 is inserted into the slot 212; and the portion of the pressing plate 220 inserted into the slot 212 is also fixed to the sliding plate 210 by a screw connection to improve the firmness of the installation of the pressing plate 220 on the sliding plate 210.
Referring to fig. 5 and 6, it is considered herein that the pressing plate 220 of the pressing assembly 200 presses the earphone module 500 when the pressing assembly 200 is in the operating position; meanwhile, the earphone module 500 may also generate a reverse force to the pressing plate 220, which may cause the pressing plate 220 to have a tendency to turn upwards and deform, so that the pressure maintaining force is reduced, which is unfavorable for pressure maintaining. In order to improve the above, the pressing assembly 200 may further include a pressing bracket 230, and the pressing bracket 230 is installed on the upper plate surface of the pressing plate 220 and is fixedly coupled to the outer plate surface of the sliding plate 210 to be supported on the sliding plate 210 and the pressing plate 220. The pressing bracket 230 may be fixed to the sliding plate 210 and the pressing plate 220 by screw connection.
Specifically, the outer plate surface of the sliding plate 210 is perpendicular to the upper plate surface of the pressing plate 220, so that a right angle area is formed between the upper plate surface of the pressing plate 220 and the sliding plate 210. The pressing bracket 230 is installed in the right angle region and is connected and fixed with the pressing plate 220 and the sliding plate 210 to form a triangle-like stable structure, so that the stability of the installation of the pressing plate 220 can be enhanced, the pressing plate 220 and the sliding plate 210 can be kept vertical, and the verticality of the pressing plate 220 and the sliding plate 210 can be improved. When the pressing plate 220 receives the reverse force of the earphone module 500, the pressing bracket 230 downwardly abuts against the pressing plate 220, thereby increasing the strength of the pressing plate 220, ensuring that the pressing plate 220 stably presses the earphone module 500.
Referring to fig. 1 to fig. 3, in an embodiment, the headset pressure maintaining mechanism further includes a guide assembly 400, the guide assembly 400 includes a plurality of guide shafts 410 extending along the same direction as the transmission shaft 310, the lower ends of the guide shafts 410 are fixedly connected to the sliding plate 210 (as shown in fig. 3 and fig. 5), and the upper ends of the guide shafts 410 are vertically movably inserted in the top plate 130.
Specifically, the pressurizing units 200 may be correspondingly configured with one or more guide units 400. Here, in order to improve the sliding stability of the pressing assembly 200, the pressing assembly 200 is correspondingly provided with two guide assemblies 400, and the two guide assemblies 400 are respectively disposed at both ends of the upper side of the sliding plate 210; the guide shaft 410 of each guide assembly 400 is disposed in the same direction as the transmission shaft 310 of the switching assembly 300, the lower end of the guide shaft 410 is fixedly connected with the sliding plate 210, and the upper end of the guide shaft 410 is movably inserted in the top plate 130 along the up-down direction, so that the sliding stability of the pressurizing assembly 200 can be guided by the cooperation of the transmission shaft 310, and the pressurizing strength of the pressurizing assembly 200 is improved.
Further, the guide assembly 400 further includes an elastic member 420, the elastic member 420 is sleeved on the guide shaft 410, the upper end of the elastic member 420 is connected with the top plate 130, and the lower end of the elastic member 420 abuts against the sliding plate 210. The elastic member 420 may be selected to be a spring. When the eccentric 320 of the switching assembly 300 is in the initial state, the driving shaft 310 of the switching assembly 300 pulls the pressurizing assembly 200 upward, so that the pressurizing assembly 200 is in the waiting position; at this time, the elastic member 420 is pressed by the slide plate 210 and the top plate 130, and elastic potential energy is accumulated. When pressure maintaining is needed, the eccentric wheel 320 of the switching assembly 300 is switched to a working state, the eccentric wheel 320 downwards releases the transmission shaft 310, the transmission shaft 310 downwards moves, and the pressurizing assembly 200 downwards slides to a pressure maintaining position; at the same time, the elastic member 420 also releases its elastic potential energy to press the pressing assembly 200 downward, increasing the pressing assembly 200 to press the earphone module 500 located on the pressure maintaining station 111, thereby being beneficial to increasing the pressure of the pressure maintaining.
In consideration of the fact that the width of the upper side of the sliding plate 210 is narrower, the area of the sliding plate 210 for the elastic member 420 to abut against is smaller, which is unfavorable for the elastic member 420 to stably abut against the sliding plate 210, so that pressure is not easily applied to the sliding plate 210. In view of this, in order to solve the problem, the guide assembly 400 may optionally further include a washer 430 disposed on the top of the sliding plate 210, the washer 430 being penetrated on the guide shaft 410; the lower end of the elastic member 420 abuts the washer 430 against the top of the sliding plate 210.
Specifically, the gasket 430 is disposed in a circular ring shape; a washer 430 is looped around the lower end of the guide shaft 410 and abuts against the sliding top. The elastic member 420 is sleeved on the guide shaft 410 and is positioned above the gasket 430; the lower end of the elastic member 420 abuts against the upper surface of the washer 430, thereby abutting the washer 430 against the top of the sliding plate 210. The gasket 430 has a large surface area so that an effective area where the gasket 430 contacts and abuts against the elastic member 420 is large, and thus the elastic member 420 can stably apply pressure to the sliding plate 210 through the gasket 430.
Referring to fig. 1, in accordance with any of the above embodiments, the base 100 is provided with a plurality of pressure maintaining stations 111; the number of the pressurizing assembly 200 and the switching assembly 300 is plural; wherein, the pressurizing assemblies 200 are respectively in one-to-one correspondence with the pressure maintaining stations 111; the plurality of switching units 300 are connected to the plurality of pressurizing units 200 in one-to-one correspondence, respectively. The specific structure and connection relationship of the pressurizing assembly 200 and the switching assembly 300 can be implemented with reference to the foregoing embodiments.

The stand upright 121 divides the base plate 110 into two parts located at both sides of the stand upright 121; two parts of the bottom plate 110 located on two sides of the stand plate 121 are provided with a pressure maintaining station 111.
Based on this, there should also be two of the number of pressurizing assemblies 200; the two pressurizing assemblies 200 are respectively installed at both sides of the mounting bracket 120 and are disposed opposite to the two pressure maintaining stations 111 in the up-down direction. Correspondingly, the number of the switching assemblies 300 is two, and the two switching assemblies 300 are mounted on the top plate 130 of the base 100 and are respectively connected with the two pressurizing assemblies 200 in a one-to-one correspondence. In this way, the two switching assemblies 300 can respectively drive the pressurizing assemblies 200 to move independently, so that the earphone pressure maintaining mechanism can simultaneously maintain pressure on the two earphone modules 500 at one time, thereby improving production efficiency; of course, the earphone pressure maintaining mechanism may also maintain pressure on the earphone modules 500 one by one, so as to improve applicability.
Optionally, the pressure maintaining station 111 is a positioning groove 111 disposed on the bottom plate 110, and a mounting notch 112 is disposed on one side of the positioning groove 111 for mounting the earphone module 500. During pressure maintaining, the earphone module 500 with the earphone 600 is pushed into the positioning groove 111 from the mounting notch 112, so that the earphone module 500 is limited in the positioning groove 111, and the earphone module 500 is not easily moved. After the pressure keeping is finished, the earphone module 500 is moved out from the mounting notch 112 of the positioning groove 111, so that the earphone module is convenient to mount and high in stability.
Referring to fig. 1, 9 to 11, according to any of the above embodiments, for the earphone module 500, the earphone module 500 includes an upper module 510 and a lower module 520, and the upper module 510 and the lower module 520 are detachably connected by a pin 530. Wherein, an upper cavity is arranged in the upper module 510; the lower module 520 is provided with a lower cavity, and the lower cavity and the upper cavity cooperate to form an earphone profiling cavity 501 for accommodating the earphone 600.
Specifically, the outer contour of the earphone module 500 may be optionally in a square configuration, and the height tolerance of the earphone module 500 does not exceed 0.02mm; a pre-pressing gap is arranged between the upper module 510 and the lower module 520 of the earphone module 500, and the height of the pre-pressing gap is 1mm; the headset module 500 is pressurized by the headset dwell mechanism by 2mm. The upper module 510 and the lower module 520 are provided with pin holes for inserting pins 530; wherein, the depth tolerance of the pin hole of the upper module 510 is 0 mm-0.04 mm; the deep tolerance of the pin hole of the lower module 520 is 0 mm-0.02 mm, so as to ensure that the pin 530 can be stably inserted into the pin hole when the earphone pressure maintaining mechanism applies pressure to the earphone module 500. In addition, the upper circumference of the lower cavity of the lower module 510 is 1mm higher than the parting line of the front and rear cases of the earphone 600, so that the parting line of the front and rear cases of the earphone 600 is located in the lower cavity of the lower module 510.
