Description

Technical Field

[0001] The invention belongs to the field of watches, and in particular relates to a replaceable battery watch strap for a smart watch. Background Art

[0002] Existing wearable smart devices such as smart bracelets and watches must be charged during nighttime use due to the limitation of battery capacity technology. Existing wearable smart devices are no longer single-function devices as before. They include personalized functions such as heart rate monitoring, temperature tracking, sleep quality evaluation, and exercise recording. Traditional wearable smart devices such as smart bracelets and watches are difficult to support sleep time at night after daytime use. And these monitoring functions must be recorded 24 hours a day.

[0003] Currently, there is a watch strap for smart watches that is equipped with multiple batteries and can be connected to the watch dial via a USB interface. However, this direct connection via USB plug is very unstable. The wearer can easily separate the watch strap and the watch dial when exercising, and the stability is poor. Summary of the invention

[0004] The purpose of the present invention is to provide a replaceable battery watch strap with simple structure and reasonable design in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A replaceable battery watchband, comprising a first watchband and a second watchband connected to a watch dial, wherein the watch dial and one end of the second watchband are both connected to a first connecting mechanism, both ends of the first watchband and the other end of the second watchband are both connected to a second connecting mechanism, and the first connecting mechanism and the second connecting mechanism are detachably connected;

[0007] The first connection mechanism includes a first connection block, a connection groove provided on the first connection block, a position limiting connection mechanism connected to the inner wall of the connection groove, and a plurality of first magnets embedded on the inner wall of the connection groove, wherein the plurality of first magnets are symmetrically distributed around the position limiting connection mechanism;

[0008] The second connection mechanism includes a second connection block, a limiting groove arranged on the second connection block, a metal plug connected to the inner wall of the limiting groove, and a plurality of second magnets inlaid on the outer wall of the second connection block and matched with the first magnets.

[0009] As a further optimization scheme of the present invention, the limiting connection mechanism includes a metal connecting rod connected to the inner wall of the connecting groove, a slot arranged in the metal connecting rod, a plurality of connecting frames connected to the outer wall of the metal connecting rod, a supporting rod hinged on the connecting frame, a limiting plate connected to the supporting rod, a spring connected between the limiting plate and the metal connecting rod, and an elastic outer layer wrapped around the outside of the metal connecting rod, and the connecting frame, supporting rod, limiting plate and spring are all located between the metal connecting rod and the elastic outer layer.

[0010] As a further optimization solution of the present invention, the first watch strap includes a plurality of outer shells and a plurality of double-layer mesh connection nodes connected between the outer shells, and a battery is arranged in the outer shells.

[0011] As a further optimization solution of the present invention, the battery, the metal connecting rod and the metal insertion rod are all electrically connected through wires.

[0012] As a further optimization solution of the present invention, the connecting frame is connected to a position close to one end of the metal connecting rod, the spring is connected to a position close to the other end of the metal connecting rod, and the length of the spring is smaller than the length of the connecting frame.

[0013] As a further optimization solution of the present invention, the outer diameter of the metal rod is the same as the inner diameter of the slot, and the axis of the metal rod and the axis of the slot are collinear.

[0014] As a further optimization solution of the present invention, the outer wall of the second connecting block is in contact with the inner wall of the connecting groove.

[0015] The beneficial effects of the present invention are:

[0016] The connection between the dial and the watch band of the present invention is more convenient and more stable. When connecting the watch band and the dial, the metal plug rod on the second connecting block is inserted into the slot in the metal connecting rod, and the metal connecting rod is inserted into the limiting groove on the second connecting block. As the metal connecting rod moves, the inner wall of the limiting groove contacts the elastic outer covering layer and the limiting plate therein, and gradually adjusts the limiting plate to a state of parallel contact with the inner wall of the limiting groove. At this time, the spring is in a stretched state, which will generate a certain pulling force on the limiting plate, so that the end away from the spring is subjected to a certain force, which can generate a certain force between the limiting plate and the inner wall of the limiting groove, playing a certain self-locking role. At the same time, under the magnetic force of the magnets that cooperate with each other, the connection between the watch band and the dial can be made more stable, and the entire connection process is relatively convenient. Similarly, the connection of other parts is as described above.

[0017] The present invention can be disassembled by directly separating the first connecting mechanism from the second connecting mechanism with a relatively large force;

[0018] The invention has the advantages of simple structure, high stability, reasonable design and easy implementation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figure 1-6 As shown, a replaceable battery watch strap comprises a first watch strap 101 and a second watch strap 102 connected to a watch dial 1, the watch dial 1 and one end of the second watch strap 102 are both connected to a first connecting mechanism 2, both ends of the first watch strap 101 and the other end of the second watch strap 102 are both connected to a second connecting mechanism 3, and the first connecting mechanism 2 and the second connecting mechanism 3 are detachably connected;

[0029] The first connection mechanism 2 includes a first connection block 201, a connection groove 202 provided on the first connection block 201, a position limiting connection mechanism 203 connected to the inner wall of the connection groove 202, and a plurality of first magnets 204 embedded on the inner wall of the connection groove 202, wherein the plurality of first magnets 204 are symmetrically distributed around the position limiting connection mechanism 203;

[0030] The second connection mechanism 3 includes a second connection block 301 , a limiting groove 302 provided on the second connection block 301 , a metal plug rod 303 connected to the inner wall of the limiting groove 302 , and a plurality of second magnets 304 embedded on the outer wall of the second connection block 301 and matching with the first magnets 204 .

[0031] The limiting connection mechanism 203 includes a metal connecting rod 2030 connected to the inner wall of the connecting groove 202, a slot 2031 arranged in the metal connecting rod 2030, a plurality of connecting frames 2032 connected to the outer wall of the metal connecting rod 2030, a supporting rod 2033 hinged on the connecting frame 2032, a limiting plate 2034 connected to the supporting rod 2033, a spring 2036 connected between the limiting plate 2034 and the metal connecting rod 2030, and an elastic outer layer 2035 wrapped around the outside of the metal connecting rod 2030. The connecting frame 2032, the supporting rod 2033, the limiting plate 2034 and the spring 2036 are all located between the metal connecting rod 2030 and the elastic outer layer 2035.

[0032] The first strap 101 includes a plurality of shells 103 and a plurality of double-layer mesh connection nodes 105 connected between the shells 103, and a battery 104 is arranged inside the shell 103. The shell 103 can be made of materials such as rubber, carbon fiber material, PVC, and waterproof cloth. The battery 104, the metal connecting rod 2030, and the metal plug rod 303 are all electrically connected through the wire 106. The wire 106 and the double-layer mesh connection nodes 105 are mixed and woven, and the wire 106 is interspersed between the double-layer mesh connection nodes 105. The double-layer mesh connection nodes 105 are woven with textile fibers, have good deformation and bending resistance effects, and will not break.

[0033] The connecting frame 2032 is connected to a position close to one end of the metal connecting rod 2030 , and the spring 2036 is connected to a position close to the other end of the metal connecting rod 2030 . The length of the spring 2036 is smaller than the length of the connecting frame 2032 .

[0034] The outer diameter of the metal rod 303 is the same as the inner diameter of the slot 2031, and the axis of the metal rod 303 is colinear with the axis of the slot 2031. After the metal rod 303 is inserted into the slot 2031, the metal rod 303 and the metal connecting rod 2030 are electrically conductive, which can effectively connect the circuit between the battery 104 and the dial 1, and the battery 104 supplies power to the dial 1, effectively improving the battery life of the watch.

[0036] When the watch strap and the watch dial 1 are connected, the metal plug rod 303 on the second connecting block 301 is inserted into the slot 2031 in the metal connecting rod 2030, and the metal connecting rod 2030 is inserted into the limiting groove 302 on the second connecting block 301. As the metal connecting rod 2030 moves, the inner wall of the limiting groove 302 contacts the elastic outer layer 2035 and the limiting plate 2034 therein, and gradually adjusts the limiting plate 2034 to a state of parallel contact with the inner wall of the limiting groove 302. At this time, the spring 2036 is in a stretched state, which will generate a certain pulling force on the limiting plate 2034, so that it is away from the spring 203 One end of 6 is subjected to a certain force, which can generate a certain force between the limit plate 2034 and the inner wall of the limit groove 302, playing a certain self-locking role. At the same time, under the magnetic force of the magnets that cooperate with each other, the connection between the strap and the dial 1 can be made more stable, and the entire connection process is relatively convenient. Similarly, the connection of other parts is as described above, such as when the first strap 101 and the second strap 102 are connected, the principle is also the connection process of the first connecting mechanism 2 and the second connecting mechanism 3. When disassembling, the first connecting mechanism 2 and the second connecting mechanism 3 can be directly separated with a greater force.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
