[0011] In one embodiment, the receiving cavity is closed on one side close to the first elastic return member, and an opening is formed on the side of the receiving cavity away from the first elastic return member. The solar panel can pass through the opening and extend out of the receiving cavity, and the opening is blocked when the solar panel is retracted into the receiving cavity.

[0012] In one embodiment, the first elastic return member is an elastic sheet, and the two ends of the first elastic return member are respectively a connecting end and a free end, the connecting end is connected to a side cavity wall of the receiving cavity along the first direction, and the free end is connected to the solar panel, and the first elastic return member is clamped between the solar panel and the cavity wall of the receiving cavity when the solar panel is retracted into the receiving cavity.

[0034] The functions of smart watches in the prior art are becoming more and more abundant, and the power consumption is also getting higher and higher. Especially for scenarios of adventure and long-term outdoor activities, it is necessary to turn on the GPS or satellite communication function for a long time, which further increases the power consumption and causes the smart watch to have poor battery life.

[0035] Please combine Figures 1 to 3 and Figure 5 ,in, Figure 3 The solar panel 12 in the middle dashed line represents the state when the solar panel 12 is retracted into the receiving chamber 11, and the first elastic reset member 13 is compressed accordingly. Figure 3 The solar panel 12 in the solid line represents the state when the solar panel 12 extends out of the receiving cavity 11. At this time, the first elastic reset member 13 is releasing the elastic restoring force and pushing the solar panel 12 out of the receiving cavity 11. In order to solve the above problem, the present invention proposes a solar charging watch 100, including a watch body 1, a battery 2 and a strap 3. The watch body 1 is formed with a receiving cavity 11, and the receiving cavity 11 is provided with a first elastic reset member 13, and one end of the first elastic reset member 13 is connected to a side cavity wall of the receiving cavity 11 along a first direction, and the other end is connected to the solar panel 12, and the watch body 1 is provided with a locking assembly Part 14, the locking component 14 can lock the solar panel 12 into the watch body 1 or unlock it from the watch body 1; the first elastic reset part 13 can be deformed when the solar panel 12 is retracted along the first direction and locked in the receiving cavity 11, and can extend the solar panel 12 out of the receiving cavity 11 along the first direction through elastic restoring force when the solar panel 12 is unlocked; the battery 2 is arranged in the watch body 1, and the solar panel 12 can be charged when it extends out of the watch body 1; the strap 3 is respectively connected to the opposite sides of the watch body 1 along the second direction, and can form a wearing hole with the watch body 1, and the first direction is different from the second direction.

[0036] During use, the wearer unlocks the solar panel 12 through the locking component 14, and the elastic restoring force of the first elastic reset member 13 pushes the solar panel 12 out of the watch body 1. The solar panel 12 receives sunlight and converts solar energy into electrical energy, which is then transmitted to the battery 2 for charging, thereby realizing charging in an outdoor environment and improving the battery life of the solar panel 12. When charging is not needed, the solar panel 12 is retracted into the watch body 1 and locked through the locking component 14, so as not to affect normal wearing. At the same time, the first elastic reset member 13 is deformed to accumulate elastic restoring force.

[0037] The technical solution of the present invention is to set a first elastic reset member 13 and a solar panel 12 connected to the first elastic reset member 13 in the receiving cavity 11 of the watch body 1. When the solar panel 12 is retracted into the watch body 1 along the first direction, the locking component 14 locks the solar panel 12 in the receiving cavity 11, and the first elastic reset member 13 is deformed. When the locking component 14 unlocks the solar panel 12 from the watch body 1, the elastic restoring force of the first elastic reset member 13 pushes the solar panel 12 out of the watch body 1 along the first direction, so that the solar panel 12 can receive sunlight and convert solar energy into electrical energy, thereby charging the rechargeable battery 2 and improving the battery life of the solar charging watch 100. At the same time, when the solar panel 12 is not needed, the solar panel 12 can be completely retracted into the watch body 1 without affecting normal wearing. The present invention improves the battery life of the solar charging watch 100 by setting the solar panel 12 to be retractable and installed in the watch body 1, and charging the battery 2 through the solar panel 12, while not affecting the normal wearing of the solar charging watch 100.

[0038] By designing the first direction and the second direction to be different, the extension and retraction of the strap 3 and the solar panel 12 do not interfere with each other, ensuring that the solar panel 12 can be smoothly extended or retracted after being unlocked, thereby improving the reliability of use. At the same time, through the built-in design of the first elastic reset member 13 and the solar panel 12, the solar panel 12 can be retracted back into the storage cavity 11 when not in use, and fixed by the locking component 14, avoiding damage to the solar panel 12 by external impact, dust or moisture, thereby extending the service life of the solar panel 12.

[0039] In one embodiment, two guide rails 15 are formed on opposite side walls of the receiving cavity 11 along the second direction. Both guide rails 15 extend along the first direction. The outer walls of the solar panel 12 along the second direction are in sliding contact with the two guide rails 15 .

[0040] The guide rail 15 extends along the first direction and cooperates with the outer wall of the solar panel 12 in sliding contact, effectively preventing the solar panel 12 from shifting or tilting during the extension and retraction process, thereby ensuring smooth movement, making the extension and retraction of the solar panel 12 more stable and smooth, improving user experience, and reducing the friction between the solar panel 12 and the wall of the receiving cavity 11, reducing wear and extending the service life.

[0041] In one embodiment, the side of the accommodating cavity 11 close to the first elastic return member 13 is closed, and an opening 16 is formed on the side of the accommodating cavity 11 away from the first elastic return member 13. The solar panel 12 can pass through the opening 16 and extend out of the accommodating cavity 11. The opening 16 is blocked when the solar panel 12 is retracted back into the accommodating cavity 11.

[0042] When the solar panel 12 is retracted into the receiving cavity 11, its edge can completely block the opening 16, thereby improving the sealing of the receiving cavity 11, preventing dust, water droplets or other debris from entering the receiving cavity 11, and protecting the internal circuit components from contamination and damage, thereby improving the reliability and durability of the equipment.

[0043] It should be noted that the first elastic reset member 13 can be arranged on a side away from the opening 16. At this time, the first elastic reset member 13 is in a compressed state when the solar panel 12 is retracted into the receiving cavity 11, and pushes the solar panel 12 out of the receiving cavity 11 through elastic restoring force when the locking assembly 14 unlocks the solar panel 12.

[0044] The first elastic reset member 13 can also be arranged on a side close to the opening 16. At this time, the first elastic reset member 13 is in a stretched state when the solar panel 12 is retracted back into the accommodating cavity 11, and pulls the solar panel 12 out of the accommodating cavity 11 through the elastic restoring force when the locking assembly 14 unlocks the solar panel 12. Two different layouts of the first elastic reset member 13 can be selected according to specific design requirements.

[0045] In one embodiment, the first elastic return member 13 is an elastic thin sheet, and the two ends of the first elastic return member 13 are respectively a connecting end 131 and a free end 132, the connecting end 131 is connected to a side cavity wall of the accommodating cavity 11 along the first direction, and the free end 132 is connected to the solar panel 12, and the first elastic return member 13 is clamped between the solar panel 12 and the cavity wall of the accommodating cavity 11 when the solar panel 12 is retracted back into the accommodating cavity 11.

[0046] The elastic sheet is compactly designed and is sandwiched between the solar panel 12 and the wall of the receiving cavity 11, making full use of the limited internal space, so that the overall thickness of the watch can be controlled, and the appearance and wearing comfort are optimized. At the same time, the elastic sheet can also reduce the overall weight of the watch, further improving the wearing experience. Specifically, the elastic sheet can be a memory metal material. The memory metal has excellent elastic properties and can maintain deformation and recovery during repeated expansion and contraction, greatly improving the service life of the first elastic reset member 13. The memory metal has good tolerance to temperature and humidity changes, is not easy to rust or age, and is particularly suitable for the use of smart watches in complex outdoor environments.

[0047] In one embodiment, the locking component 14 includes a latching rod 141 and a second elastic return member 142. A avoidance hole 17 connected to the receiving cavity 11 is opened on the watch body 1. The latching rod 141 extends into the receiving cavity 11 through the avoidance hole 17 and is connected to the cavity wall of the receiving cavity 11 through the second elastic return member 142. A slot 121 is provided at the position of the solar panel 12 corresponding to the latching rod 141. The latching rod 141 is pressed toward the solar panel 12, so that the second elastic return member 142 is deformed and the latching rod 141 is disengaged from the slot 121 and moves away from the avoidance hole 17, so as to unlock the solar panel 12 from the receiving cavity 11, so that the solar panel 12 extends out of the receiving cavity 11 under the elastic restoring force of the first elastic return member 13. The latching rod 141 can move toward the avoidance hole 17 under the elastic restoring force of the second elastic return member 142 until it is engaged with the slot 121, so as to lock the solar panel 12 in the receiving cavity 11.

[0048] Through the cooperation of the card rod 141 and the elastic reset part, the user only needs to press the card rod 141 lightly to unlock the solar panel 12. No complicated operation is required, which simplifies the use process. It is especially suitable for one-handed operation or quick adjustment in outdoor environments. The card connection between the card rod 141 and the avoidance hole 17 will not be disengaged due to the shaking of daily use, which ensures the stability of the solar panel 12 and will not pop out suddenly during daily use. The card rod 141 and the avoidance hole 17 have a simple structure and high stability, which further extends the service life.

[0049] In one embodiment, the second elastic return member 142 is a spring, and the second elastic return member 142 and the clamping rod 141 both extend along the third direction. The first direction, the second direction and the third direction are different. The clamping rod 141 can move toward or away from the avoidance hole 17 along the third direction to correspondingly disengage or clamp the clamping rod 141 in the clamping slot 121.

[0050] The spring extends along a third direction, which is different from the first direction, so that when the card rod 141 is plugged into the avoidance hole 17, the avoidance hole 17 obtains a component force different from that in the first direction, thereby making the direct plug-in fit between the card rod 141 and the avoidance hole 17 tighter, and the card rod 141 will not be separated from the avoidance hole 17 due to accidental touch, thereby improving the stability of the solar panel 12.

[0051] Please combine Figure 3 and Figure 4 ,in, Figure 4 Figure (1) is a schematic diagram of the top view of the clamping rod. Figure 4 Figure (2) is a schematic diagram of the side view structure of the clamping rod. In one embodiment, the clamping rod 141 includes a pressing rod 143, a connecting block 144 and a buckle 145. The pressing rod 143, the connecting block 144 and the second elastic return member 142 are connected in sequence along the third direction. The end of the pressing rod 143 away from the connecting block 144 along the third direction passes through the avoidance hole 17 and extends out of the accommodating cavity 11. The buckle 145 is installed on the side of the connecting block 144 facing the avoidance hole 17 and is spaced apart from the pressing rod 143.

[0052] When using, along Figure 3 The pressing rod 143 is pressed in the left and right directions of the middle right figure, and the pressing rod 143 moves rightward to drive the buckle 145 to move rightward through the connecting block 144 to disengage from the slot 121. At this time, the solar panel 12 loses the restraining force along the first direction and is pushed out of the opening by the first elastic reset member 13 and extends out of the accommodating cavity 11; after the pressing rod 143 is released, the pressing rod 143 and the buckle 145 are pushed to the left by the second elastic reset member. Therefore, when the solar panel 12 needs to be retracted back into the accommodating cavity 11, it is necessary to press the pressing rod 143 again to drive the buckle 145 to move rightward until the solar panel 12 is retracted back into the accommodating cavity 11 and the slot 121 corresponds to the buckle 145, then release the pressing rod 143, so that the second elastic reset member 142 pushes the buckle 145 to extend into the slot 121 and engage with the slot 121 to achieve the locking of the solar panel 12.

[0053] The buckle 145 and the pressing rod 143 are arranged at an interval, so that when the buckle 145 is plugged into the slot 121, the pressing rod 143 can be located on the outside of the solar panel 12, which will not affect the sliding of the solar panel 12 along the first direction. It is only necessary to open a slot 121 on the solar panel 12 that matches the size of the buckle 145, and there is no need to specially open a slot to avoid the pressing rod 143, thereby increasing the effective area of ​​the solar panel 12 and improving the power generation efficiency of the solar panel 12.

[0054] In one embodiment, the first direction and the second direction are two different directions of the plane where the watch body 1 is located, and the third direction is the thickness direction of the watch body perpendicular to the plane where the watch body 1 is located. The clamping rod 141 extends along the third direction and is perpendicular to the solar panel 12, so that the abutting force generated by the clamping rod 141 on the solar panel 12 is directly in the first direction, thereby maximizing the stability of the clamping rod 141 limiting the position of the solar panel 12.

[0055] In one embodiment, there are two receiving cavities 11, which are spaced apart along the thickness direction of the watch body 1. Two solar panels 12 are respectively disposed in the two receiving cavities 11, and both solar panels 12 can be extended and retracted along a first direction in opposite directions.

[0056] Two solar panels 12 are respectively arranged in the two receiving chambers 11, and power generation and charging can be carried out through the two solar panels 12 at the same time, thereby improving the efficiency of solar charging. The two receiving chambers 11 are spaced apart along the thickness direction, and the two solar panels 12 have opposite extension and retraction directions, which can avoid interference between the extension and retraction processes of the two solar panels 12 and improve the stability of the extension and retraction process of the solar panels 12.

[0057] In one embodiment, a sliding spring 111 electrically connected to the battery 2 is provided on the cavity wall of the receiving cavity 11, and an electrode contact area 122 extending along the first direction is provided on the solar panel 12. The electrode contact area 122 is used to slide and contact with the sliding spring 111 when the solar panel 12 is extended and retracted along the first direction. The electric energy generated when the solar panel 12 is extended out of the watch body 1 charges the battery 2 through the sliding spring 111. The electrode contact area 122 extends along the first direction and slides and contacts with the sliding spring 111, so that the solar panel 12 can always be electrically connected to the sliding spring 111 during the extension and retraction process, ensuring that no matter how the solar panel 12 is extended and retracted, the electric energy can be smoothly transmitted to the battery 2, avoiding the problem of electrical disconnection or poor contact.

[0058] In one embodiment, a boost module 4 is further provided in the watch body 1, and the solar panel 12 is electrically connected to the battery 2 via the boost module 4, and the boost module 4 is used to boost the output voltage of the solar panel 12. The output voltage of the solar panel 12 is usually low, especially under low light conditions. The low voltage of the solar panel 12 is converted into a higher voltage suitable for charging the battery 2 by the boost module 4, ensuring that the battery 2 can be charged and improving the charging efficiency.

[0059] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
