Description

Technical Field

[0001] The present invention relates to a push-type actuating device, in particular to a push-type telescopic pushing device. Background Art

[0002] The push-push button mechanism is simple in structure and can lock / release with a simple push. Therefore, the push-push button mechanism is widely used as a small deadbolt or a quick push mechanism.

[0003] Taking the quick push mechanism as an example, its operation direction is usually along the axial direction of the push rod, directly pressing the push rod. This pressing direction limits the configuration of the quick push mechanism. In addition, even in the locked state, the push rod must be appropriately exposed to allow for the next pressing operation. To solve the above problems, the existing technology uses a motor to replace the quick push mechanism to drive the push rod, such as using a solenoid valve or a motor to drive the push rod, rather than directly pressing the push rod.

[0004] Motors are expensive and complex, and require electrical power, which can lead to potential electrical failures. Summary of the Invention

[0005] Based on the above technical issues, the present invention proposes a push-type telescopic pushing device and a storage device that can be easily pressed to operate.

[0006] In order to solve the problems existing in the existing known technology, the present invention provides a push-type telescopic pushing device, including a double-push telescopic mechanism, a pressing mechanism and a first reset member. The double-push telescopic mechanism includes a buckle seat, a pushing rod and an actuating rod. The buckle seat has a first end face and a second end face relative to each other, the pushing rod and the actuating rod are coaxially arranged on the buckle seat, and the pushing rod protrudes from the first end face in the telescopic direction, and the actuating rod protrudes from the second end face. The actuating rod is used to be repeatedly pressed along the telescopic direction so that the pushing rod moves between a protruding position and a retracted position. The pressing mechanism includes a pressing rod, a cam member and a steering unit. The pressing rod is movably arranged along the pressing direction, and an angle is formed between the pressing direction and the telescopic direction. The cam member is connected to the steering unit, the steering unit is coupled to the pressing rod, and the cam member has a vertex away from the pressing rod. The steering unit is configured such that when a pressing end of the pressing rod is pressed toward the cam member in a pressing direction, the steering unit drives the cam member to rotate in the pressing direction, thereby moving the apex in the telescopic direction to press the actuating rod. The first return member is configured to normally provide a thrust to push the pressing rod away from the cam member, thereby driving the cam member via the steering unit to move the apex out of the telescopic direction.

[0007] In at least one embodiment, the push-type telescopic pushing device further includes a housing having a top surface and a side surface perpendicular to the top surface. The top surface defines a first through-hole, and the side surface defines a second through-hole. The double-push telescopic mechanism and the pressing mechanism are fixed to the housing, with the pushing rod extending through the first through-hole and protruding from the top surface, and the pressing rod extending through the second through-hole and protruding from the side surface.

[0008] Preferably, the cross-sections of the second through-hole and the pressing rod are non-circular and match each other.

[0009] Preferably, the steering unit includes a protrusion and a rotating sleeve. The protrusion is disposed on the outer circumference of the pressing rod and is configured to move parallel to the pressing direction as the pressing end of the pressing rod is pressed. The rotating sleeve is sleeved onto the pressing rod, and the cam member is disposed on the rotating sleeve. The rotating sleeve further includes a guide groove extending along a helical path along the outer circumference of the rotating sleeve, and the protrusion is slidably disposed in the guide groove.

[0010] Preferably, the guide groove has a first end and a second end, the first end extends axially toward the pressing end of the pressing rod along the axial direction of the rotating sleeve, and the second end extends axially toward the cam member, and the distance from the first end to the connection between the rotating sleeve and the cam member is greater than the distance from the second end to the connection.

[0011] Preferably, the buckle seat has a through hole connecting the first end surface and the second end surface. A stopper is provided on the first end surface, the stopper has a first through hole, and the first through hole overlaps the through hole.

[0012] The through-hole is divided into a locking section near the second end face and a movable section near the first end face. The movable section has a larger cross-section than the locking section, forming a stepped portion between the movable and locking sections. The cross-section of the first through-hole is smaller than that of the movable section. The locking section is formed with multiple chute grooves extending from the stepped portion toward the second end face. The openings of each chute form multiple locking slots on the stepped portion, allowing the multiple chute grooves and the multiple locking slots to be arranged in an alternating pattern.

[0013] The push rod has an abutting end and an opposing first rotating engagement surface. The abutting end is adapted to pass through the first through-hole. The first rotating engagement surface is provided corresponding to the stepped portion and includes a plurality of first sliders protruding radially from the push rod and spaced apart. The plurality of first sliders protrude from the first rotating engagement surface. A second reset member is provided between the stop portion and the push rod to urge the push rod toward the stepped portion.

[0014] The actuating rod has a pressure-bearing end and an opposing second rotating engagement surface. The actuating rod protrudes from the second end surface. The second rotating engagement surface has a plurality of second sliders protruding radially from the actuating rod and spaced apart. Each second slider is slidably positioned in one of the plurality of slide grooves.

[0015] The forward torque direction that revolves around the telescopic direction is defined, and the first rotating occlusal surface and the second rotating occlusal surface respectively have a plurality of spaced-apart inclined surfaces, and the plurality of inclined surfaces respectively extend along the forward torque direction and incline toward the pressure end, and the plurality of inclined surfaces of the first rotating occlusal surface and the second rotating occlusal surface are used to contact and slide relative to each other to drive the push rod to rotate along the forward torque direction so that each first slider can be embedded in each slide groove or each card slot, thereby pushing out or retracting the push rod.

[0016] Preferably, each slot has a first inclined surface extending in the forward torque direction and inclined toward the pressure-bearing end, and compared to the second end surface, each slot has a second inclined surface between it and an adjacent slide groove that is higher than the first inclined surface and inclined toward the adjacent slide groove. The multiple inclined surfaces of the first rotating occlusal surface include a first guide surface located on each first slider, which respectively matches the inclination angle of each first inclined surface and the second inclined surface. The second rotating occlusal surface has a plurality of teeth arranged radially, and each second slider corresponds to a tooth portion. The multiple inclined surfaces of the second rotating occlusal surface include a second guide surface located on each tooth portion, which matches the inclination angle of each first guide surface.

[0017] Preferably, when the actuating rod is pressed, causing the second rotating engagement surface to press against the first rotating engagement surface, the second slider corresponding to each first slider contacts the first slider with its corresponding tooth portion, causing the first guide surface and the second guide surface to contact and slide relative to each other, thereby generating a torque in the forward torque direction on the push rod. When each first slider disengages from its respective slot, the torque causes each first slider to enter the adjacent slot via the guidance of the first inclined surface, causing the push rod to move to the protruding position.

[0018] Preferably, when each first slider slides along each first inclined surface to engage with each slot, and the actuating rod is pressed again to make each first slider higher than each second inclined surface, the torque along the forward torque direction causes the first slider to move toward the next slot along the forward torque direction.

[0019] Preferably, the push-type telescopic pushing device also includes an upper shell for accommodating the buckle seat, and the first through hole is opened in the upper shell so that the part of the upper shell overlapping the first end surface forms a stopper, and the second end surface is exposed at the bottom surface of the upper shell.

[0020] Preferably, the push-type telescopic pushing device further comprises a lower shell, wherein the pressure-receiving end of the actuating rod is located in the lower shell, wherein the pressing mechanism and the first reset member are arranged in the lower shell, and the lower shell further comprises a second through-hole, and wherein the pressing end of the pressing rod passes through the second through-hole and protrudes from the lower shell.

[0021] Preferably, the cross-sections of the second through-hole and the pressing rod are non-circular and match each other.

[0022] Preferably, the first restoring member presses between the pressing rod and the inner wall of the lower shell along the pressing direction.

[0023] The present invention also provides a storage device comprising a storage housing and the aforementioned push-type telescopic pushing device. The storage housing has a hollow space, a storage groove disposed on the surface of the storage housing, and an opening at the bottom of the storage groove, communicating with the hollow space. The push-type telescopic pushing device is disposed in the hollow space, with a pushing rod corresponding to the opening, and the pushing rod protruding from the side of the storage device.

[0024] The aforementioned push-type telescopic push-pull device, through the configuration and coordinated operation of the dual-push telescopic mechanism, the pressing mechanism, and the first return element, allows for the location and direction of pressure required during operation to be varied, eliminating the need for axial pressure on the push-pull rod. Furthermore, since direct pressure on the push-pull rod is unnecessary, the push-pull rod can be configured to not protrude when in the retracted position. Therefore, the push-type telescopic push-pull device of the present invention offers greater configuration flexibility and reduces the risk of misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 1 shows a push-type telescopic pushing device 1 provided by an embodiment of the present invention, which includes a push-push button mechanism 100 , a pressing mechanism 200 , a first restoring member 300 and a housing 400 .

[0038] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the double-push telescopic mechanism 100 includes a buckle seat 110, a push rod 120, and an actuating rod 130. The buckle seat 110 has a first end surface 111 and a second end surface 112 that are opposite each other. The push rod 120 and the actuating rod 130 are coaxially arranged on the buckle seat 110. In the telescopic direction Y, the push rod 120 protrudes from the first end surface 111, and the actuating rod 130 protrudes from the second end surface 112. The actuating rod 130 is configured to be repeatedly pressed along the telescopic direction Y to move the push rod 120 between a protruding position P, where it protrudes from the first end surface 111, and a retracted position R, where it is retracted into the buckle seat 110.

[0039] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the pressing mechanism 200 includes a pressing rod 210, a cam member 220, and a steering unit 230. The pressing rod 210 is movably arranged along a pressing direction X, and an angle is formed between the pressing direction X and the extension direction Y. Specifically, the angle between the pressing direction X and the extension direction Y can be 90 degrees, but other angles are not excluded.

[0040] Combine Figure 5 、 Figure 6 and Figure 7 As shown, the cam member 220 is connected to the steering unit 230. The steering unit 230 is coupled to the pressing rod 210, and the cam member 220 has a vertex 221 away from the pressing rod 210. Figure 5 and Figure 6 As shown, the steering unit 230 is configured such that when a pressing end 212 of the pressing rod 210 is pressed toward the cam member 220 along the pressing direction X, the steering unit 230 drives the cam member 220 to rotate along the pressing direction X, thereby moving the apex 221 in the extension direction Y to press the actuating rod 130. At this time, the actuating rod 130 is pressed, driving the push rod 120 to move, thereby moving the push rod 120 from the retracted position R to the protruding position P.

[0041] like Figure 4 and Figure 7 As shown, the first reset member 300 can be a compression spring, which is sleeved on the pressing rod 210, and the two ends of the first reset member 300 respectively press against the pressing rod 21 and the inner wall of the housing 400. The first reset member 300 is used to normally provide a thrust to make the pressing rod 210 move away from the cam member 220 along the pressing direction X. Figure 7When the pressure on the pressing rod 210 disappears, the pushing force of the first restoring member 300 causes the pressing rod 210 to move away from the cam member 220 in the pressing direction X. This, in turn, drives the cam member 220 to rotate in the opposite direction via the steering unit 230. The moving apex 221 then moves away from the telescopic direction Y and returns to the state before the pressing rod 210 was pressed. At this point, due to the action of the double-push telescopic mechanism 100, the push rod 120 remains in the protruding position P.

[0042] like Figure 1 、 Figure 2 、 Figure 4 and Figure 8 As shown, the housing 400 has a top surface 410 and a side surface 420. The side surface 420 is perpendicular to the top surface 410. The top surface 410 defines a first through-hole 411, and the side surface 420 defines a second through-hole 422. The double-push telescopic mechanism 100 and the pressing mechanism 200 are fixed within the housing 400. The push rod 120 passes through the first through-hole 411 and protrudes from the top surface 410, and the pressing rod 210 passes through the second through-hole 422 and protrudes from the side surface 420. Furthermore, the cross-sections of the second through-hole 422 and the pressing rod 210 are non-circular and match each other, preventing the pressing rod 210 from rotating within the second through-hole 422. The second through-hole 422 guides the pressing rod 210, allowing it to move linearly along the pressing direction X when pressed, rather than rotating along the pressing direction X.

[0043] like Figure 4 and Figure 8 As shown, the housing 400 further includes an upper housing 401 and a lower housing 402. The upper housing 401 is used to accommodate the buckle seat 110. A first through-hole 411 is provided in the upper housing 401, so that the portion of the upper housing 401 overlapping the first end surface 111 forms a stopper 401a, and the second end surface 112 is exposed at the bottom surface 401b of the upper housing 401. The lower housing 402 is coupled to the bottom surface 401b of the upper housing 401, so that the pressure-receiving end 131 of the actuating rod 130 is located in the lower housing 402. The pressing mechanism 200 and the first return element 300 are disposed in the lower housing 402, and a second through-hole 422 is provided in the lower housing 402. The pressing end 212 of the pressing rod 210 passes through the second through-hole 422 and protrudes from the lower housing 402, and the first return element 300 abuts between the pressing rod 210 and the inner wall of the lower housing 402 along the pressing direction X.

[0044] like Figure 9 and Figure 10As shown, the steering unit 230 can be a rack and pinion combination, a rotating sleeve mechanism, or the like. In one embodiment, the steering unit 230 is a rotating sleeve mechanism and includes a bump 231 and a rotating sleeve 232. The bump 231 is disposed on the outer circumference of the pressing rod 210 and is configured to move linearly parallel to the pressing direction X as the pressing rod 210 moves. Because the second through-hole 422 and the non-circular cross-section of the pressing rod 210 restrict the rotation of the pressing rod 210, the bump 231 does not move tangentially to the outer circumference of the pressing rod 210.

[0045] Combined with reference Figure 5 、 Figure 6 、 Figure 9 and Figure 10 The rotating sleeve 232 is sleeved on the pressing rod 210, and the cam member 220 is disposed on the outer circumference of the rotating sleeve 232. The swing center of the cam member 220 is coaxial with the axis of the rotating sleeve 232. The rotating sleeve 232 further includes a guide groove 233. The guide groove 233 is generally formed along a helical path on the outer circumference of the rotating sleeve 232 and communicates with the interior of the rotating sleeve 232. The protrusion 231 is slidably disposed in the guide groove 233. When the protrusion 231 moves linearly parallel to the pressing direction X, it drives the rotating sleeve 232 to rotate along the pressing direction X.

[0046] like Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown, the guide groove 233 has a first end 233a and a second end 233b. The first end 233a extends along the axial direction of the rotating sleeve 232 toward the pressing end 212 of the pressing rod 210, and the second end 233b extends along the axial direction of the rotating sleeve 232 toward the cam member 220. On the circumference of the outer circumference of the rotating sleeve 232, the distance from the first end 233a to the connection between the rotating sleeve 232 and the cam member 220 is greater than the distance from the second end 233b to the connection. Preferably, the second end 233b is substantially located at the connection between the rotating sleeve 232 and the cam member 220. On the circumference of the outer circumference of the rotating sleeve 232, the second end 233b is located near the cam member 220. When the protrusion 231 is located at the second end 233b, the protrusion 231 drives the cam member 220 to rotate, moving the apex 221 in the extension direction Y to press the actuating rod 130. Since the rotating sleeve 232 is disposed in the lower housing 402, the first end 233a can be extended to the end of the rotating sleeve 232 to form an open state, so as to facilitate the installation of the pressing rod 210 and the protrusion 231. Figure 8 As shown, the inner wall surface of the lower housing 402 can stop the first end 233 a in the open state to prevent the protrusion 231 from falling out of the first end 233 a.

[0047] like Figure 6As shown, when the pressing end 212 of the pressing rod 210 is pressed toward the cam member 220 along the pressing direction X, the protrusion 231 moves linearly parallel to the pressing direction X, thereby driving the cam member 220 to rotate. As the cam member 220 rotates and the protrusion 231 moves, the protrusion 231 reaches the second end 233b, causing the vertex 221 to move in the extension direction Y to press the actuating rod 130.

[0048] like Figure 7 As shown, the force pressing the pressing rod 210 disappears, and the thrust of the first restoring member 300 causes the pressing rod 210 to move away from the cam member 220 in the pressing direction X. The protrusion 231 then drives the cam member 220 to rotate in the opposite direction. As the cam member 220 rotates and the protrusion 231 moves, the protrusion 231 reaches the first end 233a, causing the apex 221 to move away from the extension direction Y and return to the state before the pressing rod 210 was pressed.

[0049] See Figure 4 and Figure 11 As shown, in one embodiment, the buckle base 110 has a through-hole 113 connecting the first end surface 111 and the second end surface 112. A stopper 401a is provided on the first end surface 111. The stopper 401a has a first through-hole 411, which overlaps with the through-hole 113. The stopper 401a can be part of the upper housing 401, that is, the first through-hole 411 of the stopper 401a is the first through-hole 411 of the upper housing 401.

[0050] like Figure 4 、 Figure 12 and Figure 13 As shown, the through-hole 113 is divided into a locking section 113a near the second end surface 112 and a movable section 113b near the first end surface 111. The movable section 113b has a larger cross-section than the locking section 113a, forming a stepped portion 113c between the movable section 113b and the locking section 113a. The cross-section of the first through-hole 411 is smaller than that of the movable section 113b. A plurality of sliding grooves 113d are formed on the locking section 113a, extending from the stepped portion 113c toward the second end surface 112. Multiple locking grooves 113e are formed between the openings of each sliding groove 113d on the stepped portion 113c, so that the sliding grooves 113d and the locking grooves 113e are arranged in an alternating pattern.

[0051] like Figure 11 、 Figure 12 and Figure 13As shown, the push rod 120 has an abutting end 121 and an opposing first rotating occlusal surface 122. The abutting end 121 is used to pass through the first through-hole 411. The first rotating occlusal surface 122 is provided corresponding to the step portion 113c. The first rotating occlusal surface 122 has a plurality of first sliders 123 protruding along the radial direction of the push rod 120. The plurality of first sliders 123 are arranged at intervals and protrude from the first rotating occlusal surface 122. A second reset member 140 is provided between the stop portion 401a and the push rod 120 to push the push rod 120 toward the step portion 113c. The second reset member 140 can be a compression spring, which is sleeved on the push rod 120.

[0052] like Figure 12 and Figure 13 As shown, the actuating rod 130 has a pressure-receiving end 131 and an opposing second rotational engagement surface 132. The actuating rod 130 protrudes from the second end surface 112. The second rotational engagement surface 132 has a plurality of second sliders 133 protruding radially from the actuating rod 130. The plurality of second sliders 133 are spaced apart and each second slider 133 is slidably positioned in one of the plurality of slide grooves 113d.

[0053] Figure 14 、 Figure 15 and Figure 16 The second restoring member 140 is omitted from the drawing, and the downward arrow S represents the thrust of the second restoring member 140 on the push rod 120. A forward torque direction T is defined, which is circumferentially relative to the extension direction. The first rotating engaging surface 122 and the second rotating engaging surface 132 each have a plurality of spaced apart inclined surfaces, each extending along the forward torque direction T and inclining toward the pressure-receiving end 131. When the actuating rod 130 moves toward the push rod 120, compressing the second restoring member 140 and generating a thrust, the inclined surfaces of the first rotating engaging surface 122 and the second rotating engaging surface 132 contact each other and slide relative to each other, causing the inclined surface of the first rotating engaging surface 122 to slide relative to the inclined surface of the second rotating engaging surface 132, driving the push rod 120 to rotate along the forward torque direction T, causing each first slider 123 to engage with each slot 113d or each latching slot 113e, thereby pushing out or retracting the push rod 120.

[0054] like Figure 12 、 Figure 13 and Figure 14 As shown, each slot 113e has a first inclined surface 113e1 extending along the forward torque direction T and inclined toward the pressure-bearing end 131, and compared with the second end surface 112, each slot 113e and an adjacent slide groove 113d have a second inclined surface 113e2 higher than the first inclined surface 113e1 and inclined toward the adjacent slide groove 113d.

[0055] like Figure 12 、 Figure 13 and Figure 14 As shown, the multiple inclined surfaces of the first rotating occlusal surface 122 include a first guide surface 1231 located on each first slider 123, which matches the inclination angle of each first inclined surface 113e1 and second inclined surface 113e2. The second rotating occlusal surface 132 has a plurality of radially arranged teeth 1321, with each second slider 133 corresponding to a tooth 1321. The multiple inclined surfaces of the second rotating occlusal surface 132 include a second guide surface 1322 located on each tooth 1321, which matches the inclination angle of the first guide surface 1231, and a valley is formed between adjacent teeth 1321.

[0056] like Figure 14 and Figure 15 As shown, when each first slider 123 is located in the corresponding slot 113d, the push rod 120 is retracted to the retracted position R. When the actuating rod 130 is pressed, causing the second rotating engagement surface 132 to press against the first rotating engagement surface 122, the second slider 133 corresponding to each first slider 123 contacts the first slider 123 with its corresponding tooth portion 1321, causing the first guide surface 1231 and the second guide surface 1322 to contact each other and slide relative to each other, thereby generating a torque on the push rod 120 in the forward torque direction T. When the first slider 123 is released from the slot 113d, the torque causes the first slider 123 to enter the adjacent slot 113e via the guidance of the first inclined surface 113e1.

[0057] like Figure 16 As shown, when the pressing of the actuating rod 130 stops, the first slider 123 slides along the first inclined surface 113e1 and engages with the engaging groove 113e, so that the push rod 120 moves to the protruding position P.

[0058] like Figure 17 As shown in FIG, when the actuating rod 130 is pressed again, the position of the first slider 123 is higher than the second inclined surface 113e2, and the torque causes the first slider 123 to move toward the next slide groove 113d along the forward torque direction T. When the pressing of the actuating rod 130 stops, the first slider 123 is guided by the second inclined surface 113e2 and enters the next slide groove 113d, forming the following Figure 14 , so that the push rod 120 retreats to the retracted position R.

[0059] See Figure 18 and Figure 19, which is an application example of a press-type telescopic pushing device 1. The press-type telescopic pushing device 1 is applied to a storage device 3. The storage device 3 has a storage shell 31, the storage shell 31 has a hollow space 312, and a storage groove 311 for storing an item 4 is recessed on the surface of the storage shell. An opening 313 is provided at the bottom of the storage groove 311 to connect to the hollow space 312. In a specific embodiment, the storage device 3 may be an earphone storage box or a charging box, and the item 4 is an in-ear earphone. The press-type telescopic pushing device 1 is arranged in the hollow space 312 of the storage device 3, and the pushing rod 120 is configured corresponding to the opening 313 at the bottom of the storage groove 311, and the pressing rod 210 protrudes from the side 420 of the storage device 3 and is not located in the storage groove 311.

[0060] like Figure 18 As shown, when the push rod 120 retreats to the retracted position R, the article 4 can be placed in the receiving groove 311. Figure 19 As shown, when the push rod 210 is operated to protrude the push rod 120 to the protruding position P, the push rod 120 pushes the article 4, pushing the article 4 out of the receiving groove 311, making it easier for the user to access the article 4. When the article 4 is to be placed again, the push rod 210 is operated again to retract the push rod 120 to the retracted position R, and the article 4 can be returned to the receiving groove 311.

[0061] Based on the aforementioned push-type telescopic pushing device 1, the configuration and coordinated operation of the dual-push telescopic mechanism 100, the pressing mechanism 200, and the first return member 300 allow for the change of the required pressing position and direction during operation, eliminating the need to press the push rod 120 axially. Furthermore, since direct pressure on the push rod 120 is not required, the push rod 120 can be positioned so as not to protrude when in the retracted position R. Therefore, the push-type telescopic pushing device 1 of the present invention offers greater configuration flexibility and reduces the risk of misoperation.

[0062] The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, all equivalent changes and modifications based on the shape, structure, characteristics and spirit described in the claims of the present invention should be included in the claims of the present invention.
