Detailed Description
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. It is noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a quick-release structure, including: a first connecting piece 1, a second connecting piece 2, a first driven rod 3, a second driven rod 4 and a driving rod 5; wherein, the driving rod 5, the first driven rod 3 and the second driven rod 4 realize the assembly or disassembly between the first connecting piece 1 and the second connecting piece 2 through the mutual cooperation.
The connecting end of the first connecting piece 1 is provided with two clamping grooves, one clamping groove is arranged corresponding to the first driven rod 3, and the other clamping groove is arranged corresponding to the second driven rod 4. In this embodiment, the connection end of the first connecting member 1 is provided with a mounting groove 11, the connection end of the second connecting member 2 is accommodated in the mounting groove 11, and at this time, two clamping grooves can be formed on two opposite sidewalls of the mounting groove 11, so that the two clamping grooves are distributed on the outer sides of the first driven rod 3 and the second driven rod 4.
The first driven rod 3 and the second driven rod 4 are oppositely arranged and are arranged at the connecting end of the second connecting piece 2 in a sliding manner along the horizontal direction, and can slide until being separated from corresponding clamping grooves respectively (at the moment, the first connecting piece 1 and the second connecting piece 2 are not connected, and are in a disassembling state), or slide until being respectively clamped in the corresponding clamping grooves (at the moment, the first driven rod 3 and the second driven rod 4 are in a connecting relation with the second connecting piece 2, so that the first connecting piece 1 and the second connecting piece 2 are connected mutually, and are in an assembling state).
The driving rod 5 is slidably arranged above the first driven rod 3 and the second driven rod 4 along the vertical direction and is used for driving the first driven rod 3 and the second driven rod 4 to slide to be separated from corresponding clamping grooves in a mechanical mode or an electromagnetic mode in the downward sliding process.
It should be noted that, the driving rod 5 may be slidably mounted above the two driven rods in various conventional manners, so long as the driving rod 5 is ensured to be able to descend to a designated height position when an external force is applied and automatically ascend to an original height position when the external force is eliminated, for example, by using a spring arrangement, which is not limited in the embodiment of the present invention.
According to the quick-dismantling structure, the driving rod 5 is pressed, so that the two driven rods can be driven to shrink and slide, and the two driven rods are separated from the second connecting piece 2 until the two driven rods are separated from the corresponding clamping grooves respectively, so that the first connecting piece 1 and the second connecting piece 2 are separated; on the contrary, when the driving rod 5 ascends, the two driven rods expand and slide until the two driven rod parts are respectively clamped with the corresponding clamping grooves, and the first connecting piece 1 and the second connecting piece 2 are assembled.
In short, with the quick-release structure, the first connecting piece 1 and the second connecting piece 2 can be separated by pressing the driving rod 5, and the first connecting piece 1 and the second connecting piece 2 can be connected after the driving rod 5 is reset. The whole quick-release structure only relates to the first connecting piece 1, the second connecting piece 2, the first driven rod 3, the second driven rod 4 and the driving rod 5, compared with the prior art, the number of the disassembly pieces is greatly reduced, the disassembly structure is simplified, and the production cost is reduced. Moreover, after the assembly, the inner disassembling parts (such as the first driven rod 3 and the second driven rod 4) are completely hidden in the inner part, and the inner connecting structure cannot be seen from the outer part, so that the consistency of the whole appearance is improved, and the visual effect is better.
In an alternative embodiment, the driving rod 5 drives the first driven rod 3 and the second driven rod 4 to slide out of the corresponding clamping grooves in a purely mechanical way during the downward sliding process.
Referring to fig. 2, a first push block 51 and a second push block 52 are provided at the bottom of the driving rod 5; an elastic piece 6 is connected between the first driven rod 3 and the second driven rod 4; the first push block 51 is positioned on the outer side of the first driven rod 3, and the inner side of the first push block 51 and the outer side of the first driven rod 3 are provided with matched inclined surfaces; the second push block 52 is positioned at the outer side of the second driven rod 4, and inclined surfaces matched with each other are arranged at the inner side of the second push block 52 and the outer side of the second driven rod 4; during the descending process of the driving rod 5, the driving rod 5 pushes the first driven rod 3 and the second driven rod 4 to perform the contraction movement through the inclined surface.
In the purely mechanical way, the matching surfaces of the driving rod 5 and the driven rods are inclined surfaces, so that in the descending process of the driving rod 5, the first push block 51/the second push block 52 which are close to the outer sides of the first driven rod 3/the second driven rod 4 can push the corresponding driven rod to slide towards the central position, and simple and effective contraction movement is realized. After the driving rod 5 is lifted, the two driven rods will expand due to the restoring elastic force of the elastic member 6 until part of the driven rods extends out of the mounting groove 11.
In another alternative embodiment, the driving rod 5 drives the first driven rod 3 and the second driven rod 4 to slide out of the corresponding clamping grooves in an electromagnetic manner during the downward sliding process, which specifically includes the following examples:
example 1
Referring to fig. 3, the quick release structure of the present embodiment further includes a power source and an intermediate magnetic block 7, wherein the intermediate magnetic block 7 is specifically an electromagnet, a charging circuit is formed between the power source and the intermediate magnetic block 7, and the first driven rod 3 and the second driven rod 4 are made of metal materials (such as iron).
The middle magnetic block 7 is fixedly arranged between the first driven rod 3 and the second driven rod 4; an elastic piece 6 is connected between the middle magnetic block 7 and the first driven rod 3, and another elastic piece 6 is connected between the middle magnetic block 7 and the second driven rod 4.
When the driving rod 5 descends to exceed a preset distance, the charging loop is conducted, and electromagnetic attraction force generated by the middle magnetic block 7 on the first driven rod 3 and the second driven rod 4 is larger than the elastic force of the elastic piece 6.
In this implementation, when the charging circuit is in the on state, the intermediate magnetic block 7 generates a magnetic attraction force to the two driven rods, and the magnetic attraction force is greater than the elastic force of the elastic member 6, so as to promote the two driven rods to perform the contraction motion. At the moment when the charging circuit is switched from the conducting state to the non-conducting state, the magnetic attraction generated by the middle magnetic block 7 disappears, and the compressed elastic piece 6 pushes the two driven rods to perform expansion movement due to elastic recovery until the two driven rods partially extend out to be clamped with the clamping grooves of the first connecting piece 1. When the charging circuit is in a non-conducting state, the middle magnetic block 7 does not generate magnetic attraction, and the two driven rods are kept in a state of being separated from the clamping grooves of the first connecting piece 1 under the action of the elastic piece 6.
Example 2
Referring to fig. 4, the quick release structure of the present embodiment further includes two power sources;
the first driven rod 3 and the second driven rod 4 are electromagnets, and a charging loop is respectively formed between the first driven rod 3 and one power supply and between the second driven rod 4 and the other power supply; an elastic piece 6 is connected between the first driven rod 3 and the second driven rod 4;
when the driving rod 5 descends beyond a preset distance, the charging circuit is conducted, and electromagnetic attraction generated between the first driven rod 3 and the second driven rod 4 is larger than the elastic force of the elastic piece 6.
Example 2 is different from example 1 in that the former adopts a mode of using an electromagnet for both driven bars, and the latter adopts a mode of disposing an intermediate magnetic block 7 between both driven bars; the implementation principle of the two is basically the same: when the charging loops of the electromagnets are conducted, the electromagnets can generate magnetic attraction force so as to promote the two driven rods to perform shrinkage motion. Similarly, due to the elastic member 6, after the magnetic attraction force is eliminated, the two driven rods can perform expansion movement under the elastic restoring action of the elastic member 6.
Example 3
Referring to fig. 5, the quick release structure of the present embodiment further includes a power source;
the first driven rod 3 is an electromagnet, and a charging loop is formed between the first driven rod 3 and the power supply; the second driven rod 4 is made of metal; an elastic piece 6 is connected between the first driven rod 3 and the second driven rod 4;
when the driving rod 5 descends beyond a preset distance, the charging circuit is conducted, and the electromagnetic attraction force generated by the first driven rod 3 on the second driven rod 4 is larger than the elastic force of the elastic piece 6.
In example 3, one of the two driven levers is an electromagnet, and the other is a metal material that can be magnetically attracted, and a magnetic attraction effect can be achieved between the two levers when the charging circuit is on.
It should be noted that, among the above three different electromagnetic modes, the charging circuit involved may be implemented through software control, for example: when the active rod 5 is identified to be pressed, the charging loop is controlled to be conducted through software, so that the middle magnetic block 7 generates magnetic attraction.
Besides the software control mode, the embodiment of the invention also provides a contact conduction mode: as shown in fig. 3 to 5, a first electric connection plate 8 and a second electric connection plate 9 are fixedly arranged on each electromagnet, and the first electric connection plate 8 and the second electric connection plate 9 are positioned in the sliding stroke of the driving rod 5;
the power supply is arranged on the first electric connection plate 8, the driving rod 5 is made of conductive materials, and the driving rod 5, the power supply, the first electric connection plate 8, the electromagnet and the second electric connection plate 9 form a charging loop;
when the driving rod 5 descends beyond a preset distance, the driving rod 5 is contacted with the first electric connecting plate 8 and the second electric connecting plate 9, so that the charging loop is conducted.
By applying the contact conduction mode, the charging loop can be conducted by directly pressing the driving rod 5 to a certain distance, and the operation is simple and reliable.
In practical application, in order to guarantee to press the less return circuit that can trigger of range and switch on to promote user's use experience, the bottom of initiative pole 5 still is equipped with: a first push rod 53 made of a conductive material for contacting the first electric connection plate 8 when the driving rod 5 descends beyond a preset distance; the second push rod 54 is made of conductive material and is used for contacting the second electric connection plate 9 when the driving rod 5 descends beyond a preset distance.
It will be appreciated that the lengths of the two push rods can be flexibly designed according to practical requirements, and the embodiment of the invention is not limited thereto.
In addition, in order to ensure the sliding reliability of the first driven rod 3 and the second driven rod 4, the connecting end of the second connecting piece 2 is provided with a containing space 21, the bottom surface of the containing space 21 is provided with a sliding groove 22, and the driven rod and the second driven rod 4 are slidably arranged in the sliding groove 22; through holes are arranged on two opposite side walls of the accommodating space 21 for the first driven rod 3 and the second driven rod 4 to slide and extend.

It can be appreciated that the wearable device can be various products such as watches, glasses, bracelets, necklaces, waistbands, and the like.
