Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present invention provides an embodiment, a push-button spring type earphone mechanism, which includes a case 1 connected to an end of a watch band, two ends of the case 1 are respectively provided with an earphone rod 2, the earphone rods 2 are used for being inserted into the watch case, an elastic member 3 is connected between the adjacent ends of the two earphone rods 2, and the case 1 is further provided with a push-button block 4. The elastic part 3 is a special-shaped elastic rod, the special-shaped elastic rod comprises a U-shaped rod part 30, two ends of an opening of the U-shaped rod part 30 extend outwards to form deformation rods 31, the two ear generating rods 2 are connected with the two deformation rods 31 in a one-to-one correspondence mode, and the button block 4 presses the U-shaped rod part 30 to enable the U-shaped rod part 30 to be elastically deformed so as to drive the deformation rods 31 to swing in a reciprocating mode.

Specifically, casing 1 comprises towards the outer shell like the dial orientation of wrist-watch and towards the inner shell of wearer's wrist skin, after outer shell and inner shell joint shaping, the moving direction of button piece 4 moves to the inner shell from the outer shell, namely outer shell and inner shell have formed the stroke passageway of a button piece 4 jointly, and the outer shell can carry on spacingly to button piece 4, prevent it to drop, casing 1's appearance can be designed into similar T type structure, namely, the both ends of horizontal structure respectively set up one and give birth to ear pole 2, some other spare parts are installed to the mid portion, when so with the end connection of casing 1 and watchband, only need to expose button piece 4 and give birth to ear pole 2 at the tip of watchband can, when keeping convenient to use, can also play pleasing to the eye effect.

When two lug generating rods 2 are required to be locked in a shell 1, the button block 4 is pressed to enable the button block 4 to apply acting force to a U-shaped rod part 30 of a special-shaped elastic rod, the distance between the open ends of the U-shaped rod part 30 is close to each other after the U-shaped rod part is stressed to drive two deformation rods 31 to be close to each other, the two lug generating rods 2 connected with the deformation rods 31 are close to each other and gradually locked in the shell 1, so that if a previous watchband is connected with the watchcase, the lug generating rods 2 are completely separated from lug generating holes in the watchcase, the watchband can have component force with the watchcase, if the previous watchband is not connected with the watchcase, the lug generating rods 2 are retracted into the shell 1, the end parts of the watchband can be close to the connecting positions on the watchcase, the pressing force of the button block 4 can be removed after the lug generating rods 2 can be aligned with the lug generating holes in the watchcase, and then a part of the U-shaped rod part of the deformation rods 30 is acted with rebound force to enable the two deformation rods 31 to be far away from each other, so that the lug generating rods 2 extend out of the shell 1 and the U-shaped elastic rod 30 to be acted with the restoring force to restore the pressing block 4.

Wherein, when the button block 4 is pressed on the U-shaped rod portion 30, the size of the opening end of the U-shaped rod portion 30 can be reduced, and the two deformation rods 31 are close to each other, and in the prior art, there are many structures that can realize this action, for example:

two wedge blocks arranged in a regular splayed structure are arranged at the position where the key block 4 is contacted with the U-shaped rod part 30, in an initial state, the U-shaped rod part 30 is contacted with the lower end of a wedge surface on the wedge block, when the key block 4 applies force to the U-shaped rod part, the wedge surface of the wedge block applies extrusion force to the U-shaped rod part 30, the wedge surface serves as a reference object, the U-shaped rod part 30 moves towards the high end along the lower end of the wedge surface, the size between the open ends of the U-shaped rod part 30 gradually decreases, the U-shaped rod part 30 is extruded to generate elastic deformation and accumulate elastic potential energy, when the force pressing the key block 4 is removed, the accumulated elastic potential energy of the U-shaped rod part 30 is released, the wedge surface serves as the reference object, the U-shaped rod part 30 moves towards the low end along the high end of the wedge surface under the action of resilience force, the size of the open end of the U-shaped rod part 30 increases, and if the U-shaped rod part 30 serves as the reference object, the key block 4 can move along the opposite direction of the pressing direction under the action of the resilience force until the reset.

The invention has the advantages that the U-shaped rod part 30 of the special-shaped elastic rod is enabled to generate elastic deformation by pressing the key block 4, and elastic potential energy is accumulated, so that the U-shaped rod part 30 drives the two lug generating rods 2 to mutually approach through the two deformation rods 31 extending outwards, and the two lug generating rods 2 can retract into the shell 1, thereby facilitating the connection and the disassembly of the shell and the shell, when the pressing force of the key block 4 is removed, the elastic potential energy accumulated by the U-shaped rod part 30 is released, the two lug generating rods 2 are driven to mutually separate through the two deformation rods 31, and the key block 4 can be driven to reset at the same time, so that the joint resetting of the lug generating rods 2 and the key block 4 can be realized through one elastic piece 3, and the problem of clamping stagnation generated when the two reset is avoided.

The invention provides a push-button spring type lug generating mechanism, preferably, a guide rod 5 is arranged at the joint of a straight line section and a circular arc section of a U-shaped rod part 30 in a shell 1, the side wall of the shell 1 and the two guide rods 5 jointly form a limit for the motion stroke of the U-shaped rod part 30, namely, the joint of the straight line section and the circular arc section is limited between the guide rod 5 and the side wall of the shell 1.

Specifically, when the U-shaped rod portion 30 is pressed by the button block 4, the U-shaped rod portion 30 needs to move along the pressing direction, and the position of the U-shaped rod portion cannot be shifted, otherwise, the size of the opening end of the U-shaped rod portion 30 may be reduced, and the size of the opening end of the U-shaped rod portion cannot completely meet the travel distance required by the lug generation rod 2 to be retracted into the housing 1, so that the guide rod 5 is arranged, and the problems are avoided.

The invention provides a push-button spring type lug generating mechanism, and further, the U-shaped rod part 30 is composed of a first U-shaped section 300 and a second U-shaped section 301 arranged in the middle of the first U-shaped section 300, the second U-shaped section 301 is obliquely arranged on the first U-shaped section 300, the opening direction of the second U-shaped section 301 is opposite to that of the first U-shaped section 300, at the moment, two ends of the second U-shaped section 301 are respectively connected with the first U-shaped section 300 to form a structure similar to an M shape integrally, the second U-shaped section 301 and the first U-shaped section 300 share a vertical section, and the arc-shaped section of the second U-shaped section 301 is abutted against the inner wall of the shell 1.

Specifically, when the U-shaped rod portion 30 is pressed by the key block 4, the first U-shaped section 300 is under the effect of the wedge block 6, the open end is close to each other, elastic deformation occurs, if the key block 4 is continuously pressed, the first U-shaped section 300 can move along the pressing direction, the first U-shaped section can extrude the second U-shaped section 301, the shell 1 has a limiting effect on the second U-shaped section 301, so the second U-shaped section 301 can not move along the force direction, the joint of the first U-shaped section 300 and the second U-shaped section 301 is stressed to elastically deform, two parts of the whole U-shaped rod portion 30 are elastically deformed, and the deformation directions are perpendicular to each other.

After the pressing force of the key block 4 is removed, the elastic potential energy accumulated at two positions of the U-shaped rod part 30 needs to be released, when the elastic potential energy of the first U-shaped section 300 is released, the distance of the opening end of the first U-shaped section is increased, the first U-shaped section can move towards the lower end along the high end of the wedge-shaped surface, at the moment, the wedge-shaped surface can generate certain resistance to the movement of the first U-shaped section 300, and the elastic potential energy at the connecting position of the first U-shaped section 300 and the second U-shaped section 301 is released, so that the whole U-shaped rod part 30 can move along the direction opposite to the pressing direction, therefore, the interaction force between the first U-shaped section 300 and the wedge-shaped surface can be reduced, the opposite resetting of the key block 4 can be realized under the releasing of the two elastic potential energies, and the problem that the clamping stagnation is generated when the ear generating rod 2 and the key block 4 are reset is further avoided.

The invention provides a button spring type lug generating mechanism, preferably, wedge blocks 6 are respectively arranged at two ends of an opening of the U-shaped rod part 30 in the shell 1, wedge surfaces of the two wedge blocks 6 are arranged in an inverted V-shaped structure, and the wedge surfaces of the U-shaped rod part 30 and the wedge blocks 6 are mutually abutted.

Specifically, the two wedge-shaped blocks 6 are inverted, that is, the wedge-shaped surfaces of the two wedge-shaped blocks 6 are arranged in an inverted V-shaped structure, so that when the resilience force of the U-shaped rod part 30 is utilized, the two lug rods 2 can be driven to reset, and in the process, the U-shaped rod part can move towards the high end along the low end of the wedge-shaped surface, that is, the end part of the U-shaped rod not only has deformation that the two ends are close to and separated from each other, but also has deformation in the horizontal direction at the moment and in the direction perpendicular to the plane of the U-shaped rod, that is, the deformation in the vertical direction at the moment, meanwhile, the deformation rod 31 is rotatably connected with the lug rods 2, that is, the deformation rod 31 can swing relative to the lug rods, and thus, the deformation of the vertical direction of U type pole can drive the ear pole 2 of giving birth to equally and carry out axial displacement, so can supply the not enough of horizontal direction deformation through the removal of vertical direction, save space more, only rely on pressing of button piece 4 simultaneously can realize the deformation of level and vertical direction, moreover, the synchronous drive button piece that resumes the stroke of this deformation point resets and give birth to ear pole 2 and reset, two structures that not only realized an elastic component and go to reset, and it goes to reset two structures to be a deformation point of an elastic component, furthermore, wedge 6's weight can not superpose on button piece 4, with this reset that is more convenient for drive button piece 4, play certain laborsaving effect.

As described above, two wedge blocks 6 are disposed at the contact position of the key block 4 and the U-shaped rod portion 30, and the size of the open end of the U-shaped rod portion 30 is desired to be small, and the closer to the open end, the easier the pressing force is, and therefore, the key block 4 and the wedge blocks 6 are disposed separately, so that when the key block 4 presses the U-shaped rod portion 30, the wedge surface of the wedge block 6 does not need to be large for the reaction force applied at the open end of the U-shaped rod portion 30, the size of the open end of the U-shaped rod portion 30 is small, and the reaction force applied to the open end of the U-shaped rod portion 30 by the wedge block 6 is derived from the component of the pressure applied to the U-shaped rod portion 30 by the key block 4, and therefore, the position setting of the wedge block 6 can play the role of labor saving and leverage again, and does not affect the resetting of the two lug rods 2 and the resetting of the key block 4.

In the wearing process of the watch, collision is inevitable, if the key block 4 is pressed due to collision, the U-shaped rod part 30 drives the two lug rods 2 to be pulled out from the lug holes through the two deformation rods 31, the watch band is separated from the watch case, and the problem that the watch falls to the ground and is broken is caused.

The invention provides a key spring type earphone mechanism, and further provides a key block 4 which is composed of a first layer plate 40, a second layer plate 41 and a third layer plate 42 and is sequentially arranged in parallel along a pressing direction, a transmission direction adjusting mechanism 43 is arranged in the second layer plate 41, and the first layer plate 40 drives the third layer plate 42 to relatively move based on the transmission mode of the transmission direction adjusting mechanism 43.

The guide rod 5 is provided with a first inclined surface 44 at one end along the opposite pressing direction, the third layer plate 42 is provided with a second inclined surface 45, and the first inclined surface 44 is abutted against the second inclined surface 45 in the initial state.

Specifically, when the key block 4 is not to be pressed, the second inclined surface 45 on the third layer plate 42 abuts against the first inclined surface 44 on the guide rod 5, and the key block 4 is limited by the abutting action of the first inclined surface 44 and the second inclined surface 45 when the key block 4 is required to be pressed, the first layer plate 40 is required to be pushed to move first, so that the third layer plate 42 moves in the direction opposite to the moving direction of the first layer plate 40 under the action of the transmission direction-adjusting mechanism 43, so that the second inclined surface 45 can be separated from the first inclined surface 44, then the whole key block 4 moves in the pressing direction to gradually press the U-shaped rod part 30 when the key block 4 is pressed, and even if the key block is collided by two forces which are basically not combined with the above conditions, the key block 4 can realize the function of preventing mistake collision.

When the second inclined surface 45 is separated from the first inclined surface 44 first, the second inclined surface 45 does not move along the inclined direction of the inclined surface, the second inclined surface 45 is not contacted with the first inclined surface 44 before the second inclined surface is completely dislocated, then the blocking effect of the third layer plate 42 from the guide rod 5 is gradually reduced along the process that the high end of the second inclined surface 45 reaches the high end of the first inclined surface 44 in the process that the key block 4 is reset after being not pressed, the third layer plate 42 also starts to reset under the action of the transmission direction adjusting mechanism 43 when the high end of the second inclined surface 45 reaches the low end of the first inclined surface 44, the second inclined surface 45 also moves along the inclined direction of the first inclined surface 44 in the process that the key block 4 is reset, and therefore, after the key block 4 is completely reset, the first inclined surface 44 plays a supporting role on the second inclined surface 45, and the problem that the whole key block 4 shakes in the wearing process is avoided.

The invention provides a key spring type lug generating mechanism, preferably, the transmission direction adjusting mechanism 43 comprises a cavity 430 arranged in the second layer plate 41, the cavity 430 is in a square structure, two first sliding blocks 431 are arranged in the cavity 430 in a sliding manner, the two first sliding blocks 431 are respectively fixedly connected to the first layer plate 40 and the second layer plate 41, and air bags 432 are arranged at two ends of the cavity 430 in the moving direction of the first sliding blocks 431.

Specifically, when the first layer board 40 is pushed to move, the first layer board 40 drives the first sliding block 431 connected with the first layer board 40 to be in the cavity 430, the air bag 432 in front of the first layer board 40 in the moving direction is squeezed, and the squeezed air bag 432 deforms along the place with small stress, so that the air bag 432 squeezes the first sliding block 431 connected with the third layer board 42, and when the first sliding block 431 is squeezed to move, the air bag 432 in front of the first layer board 40 in the moving direction can be squeezed, so that the moving directions of the first layer board 40 and the third layer board 42 can be opposite, when the first layer board 40 loses the pushing force, the deformation of the air bag 432 needs to be recovered, and the deformation of the air bag 432 can reversely act on the first sliding block 431 until the first layer board 40 and the third layer board 42 return to the initial positions.

The invention provides a key spring type lug generating mechanism, further, when the key block 4 presses the U-shaped rod part 30, the second layer plate 41 presses the U-shaped rod part 30, a second sliding block 7 is arranged at the position where the second layer plate 41 presses the U-shaped rod part 30 and slides along the moving direction of the lug generating rod 2, a buckle 8 is rotatably arranged on the second sliding block 7, the rotating axis of the buckle 8 is perpendicular to the axial center line of the buckle, and the U-shaped rod part 30 is movably connected with the buckle 8.

Specifically, because the connecting position of the deformation rod 31 and the ear generating rod 2 hinders the whole deformed elastic rod from moving along the pressing direction when the deformed elastic rod is pressed, the U-shaped rod part slides and rotates at the position where the key block 4 is in contact with the U-shaped rod part 30, and both the U-shaped rod part and the U-shaped rod part are worn, in one embodiment of the invention, the buckle 8 is connected with the U-shaped rod part, the connection between the U-shaped rod part and the U-shaped rod part can slide or rotate, the buckle 8 can rotate on the second sliding block 7, and the second sliding block 7 can slide on the second layer plate 41, so that various motion conditions occurring when the U-shaped rod part 30 is pressed can be adapted.

The invention provides a button spring type lug generating mechanism, preferably, the air bag 432 is extruded by the first sliding block 431 to have fluidity, so that the movement of the first sliding block 431 is facilitated, the force required by the deformation of the material of the air bag 432 is not required to be overcome, and the air with the density smaller than that of air is filled in the air bag 432, so that the whole weight of the button block 4 can be reduced, and the wearing comfort is improved.

The invention provides a key spring type lug generating mechanism, and further, in an initial state, when a second sliding block 7 slides along the moving direction of a lug generating rod 2, the end part of a third layer plate 42 generates obstruction on the second sliding block 7; specifically, in the foregoing, the mutual support of first inclined plane 44 and second inclined plane 45 can play the effect of preventing the mistake from bumping to button piece 4, but first U-shaped section 300 takes place in U-shaped pole portion 30 and does not be used for spacing mechanism in the direction of elastic deformation, consequently when first inclined plane 44 does not stagger with second inclined plane 45, the tip of third plywood 42 can produce the hindrance to the slip of second slider 7, and second slider 7 cooperation buckle 8 can play certain limiting action in the direction that elastic deformation took place in U-shaped pole portion 30, also played certain supporting role to whole dysmorphism elastic bar, so the effect of preventing the mistake from bumping of button piece 4 is better.

As shown in fig. 5, the present invention provides another embodiment, and a key spring type earphone generating mechanism includes a transmission stroke adjusting mechanism 9, which is arranged at a connection position between a deformation rod 31 and an earphone generating rod 2 and is used for increasing a displacement stroke of the earphone generating rod 2 driven by the deformation rod 31.
