Description

Technical Field

[0001] The present invention relates to the technical field of smart wearable devices, and particularly to a smart watch. Background Art

[0002] With the development of electronic technology, smart wearable devices such as smart watches and smart bracelets are becoming more and more popular among people. Smart watches and smart bracelets generally adopt the form of Pogo Pin magnetic attraction. Pogo Pin magnetic charging relies on the attraction of the positive and negative poles of the magnet, and automatically adsorbs within a certain distance through magnetism to connect the charging head with the smart bracelet, achieving the charging effect.

[0003] In the existing smart watches, the magnet and the charging Pogo Pin are both arranged on the back of the watch, which requires a large amount of bottom space, leaving no more space at the bottom of the smart watch to arrange new functions. In addition, the charging port is placed on the back of the smart watch, and when charging, the smart watch needs to be removed or flipped, which is not only troublesome to operate, but also unable to collect the user's physiological parameters during charging. Summary of the Invention

[0004] The purpose of the present invention is to provide a smart watch, which is not only simple to operate, but also can collect the user's physiological parameters during charging, facilitating the user's use.

[0005] The technical solution provided by the present invention is as follows:

[0007] A housing, including a bottom plate and side walls surrounding the edge of the bottom plate, and a plurality of mounting holes are provided on the side walls;

[0008] An annular magnet, attached to the inner side of the side wall and arranged around the mounting holes;

[0009] A plurality of charging Pin pins, respectively passing through the mounting holes and extending into the annular magnet, and the charging Pin pins are arranged in one-to-one correspondence with the mounting holes.

[0010] Further preferably, the side wall includes a first side wall, a second side wall, a third side wall and a fourth side wall. The first side wall and the second side wall are oppositely arranged, the third side wall and the fourth side wall are oppositely arranged, the first side wall and the second side wall are respectively connected to the watch strap of the smart watch, a plurality of the mounting holes are provided on the third side wall along the length direction of the watch strap, and the annular magnet is attached to the inner side of the third side wall.

[0011] Further preferably, the fourth side wall is provided with a speaker hole and a button.

[0012] Further preferably, the two ends of the annular magnet along the length direction of the strap of the smart watch have opposite magnetic poles.

[0013] Further preferably, the annular magnet is strip-shaped, and the length of the annular magnet along the length direction of the strap is greater than the length of the annular magnet along the height direction of the smart watch.

[0014] Further preferably, the annular magnet includes a first annular magnet and a second annular magnet. The first annular magnet is sleeved outside the second annular magnet. The two ends of the first annular magnet along the length direction of the strap have opposite magnetic poles. The two ends of the second annular magnet along the length direction of the strap have opposite magnetic poles. The ends of the first annular magnet and the second annular magnet adjacent to each other have opposite magnetic poles.

[0015] Further preferably, a charging slot is provided in the area of the outer side wall of the third side wall corresponding to the annular magnet, and the end of the charging Pin needle extends into the charging slot.

[0016] Further preferably, the opening area of the charging slot is larger than the bottom area of the charging slot.

[0017] Further preferably, it further includes a pulse sensor, a photoelectric sensor and a SIM card slot seat, and the pulse sensor, the photoelectric sensor and the SIM card slot seat are respectively arranged on the bottom plate.

[0018] Further preferably, it further includes an external charging cable. The external charging cable includes a charging head. The charging head includes a charging head housing, a charging head magnet and a charging head Pin needle. The charging head magnet and the charging head Pin needle are both arranged in the charging head housing. The charging head magnet is annular, and the charging head magnet is sleeved around the outer side of the charging head Pin needle. When the charging head magnet is attracted to the annular magnet, the charging head Pin needle is connected to the charging Pin needle.

[0019] The technical effects of the present invention are as follows:

[0020] (1) By setting the magnet for adsorption as annular and arranging the charging Pin needle inside the annular magnet, the volume of the charging port can be reduced, so that the charging port can be arranged at the side wall of the smart watch, making it unnecessary to remove the smart watch during charging. This is not only convenient to operate, but also the smart watch can still collect the physiological parameters of the user, facilitating the use of the user.

[0021] (2) By setting the two ends of the annular magnet to have different polarities, it can prevent reverse insertion during charging and improve the user experience.

[0022] (3) The annular magnet is set to two inner and outer magnets, and the poles of the adjacent ends of the magnets are opposite, which can improve the docking accuracy between the charger head and the charging port on the smart watch and prevent misalignment during docking.

[0023] (4) The charging slot on the first side wall is set to be trumpet-shaped. When the charger head is docked with the charging slot, the position of the charger head can be adjusted through the charging slot, so as to achieve the precise docking between the charging Pin on the charger head and the charging Pin on the smart watch, and improve the docking accuracy.

[0038] Embodiment 1

[0039] An intelligent watch, as Figure 1 and Figure 2 shown, includes a housing 10, an annular magnet 20, and a plurality of charging Pin pins 30. The housing 10 includes a bottom plate 11 and a side wall surrounding the edge of the bottom plate 11. The side wall includes a first side wall 12 and a second side wall 13 arranged opposite to each other, as Figure 1As shown, the first side wall 12 and the second side wall 13 are respectively used to connect the watch band 40 of the smart watch. The side walls further include a third side wall 14 and a fourth side wall 15 which are oppositely arranged. The first side wall 12, the third side wall 14, the second side wall 13 and the fourth side wall 15 are sequentially connected end to end to form a closed loop. The side walls and the bottom plate 11 can jointly form a receiving cavity. The bottom plate 11 and the side walls can be integrally injection-molded or assembled. For example, after the side walls and the bottom plate 11 are respectively formed, the side walls and the bottom plate 11 are fixedly connected by means of dispensing.

[0040] The third side wall 14 is provided with a plurality of mounting holes along the length direction of the watch band 40; the annular magnet 20 is attached to the inner side of the third side wall 14 and arranged around the mounting holes; the cross-section of the annular magnet 20 can be in the shape of a circular ring, an ellipse or a square, etc. The fourth side wall 15 of the smart watch is provided with a speaker hole and a button. By arranging both the speaker hole and the button on the fourth side wall 15 of the smart watch, there is enough space on the third side wall 14 of the smart watch to set the charging port of the smart watch, that is, both the annular magnet 20 and the charging Pin pins 30 are arranged at the third side wall 14.

[0041] For the convenience of installing the annular magnet 20, the inner wall of the third side wall 14 is provided with a mounting groove 141 adapted to the annular magnet 20, and the annular magnet 20 is bonded in the mounting groove 141. Arranging the mounting groove 141 on the inner side of the third side wall 14 to install the annular magnet 20 can reduce the volume of the annular magnet 20 occupying the internal receiving cavity of the smart watch, so as to facilitate the arrangement of other components such as the circuit board in the receiving cavity.

[0042] A plurality of charging Pin pins 30 respectively pass through the mounting holes and extend into the annular magnet 20, and the charging Pin pins 30 are arranged in one-to-one correspondence with the mounting holes. Arranging a plurality of charging Pin pins 30 in the annular magnet 20 can reduce the volume occupied by the magnet and the charging Pin pins 30, that is, reduce the volume occupied by the entire charging port, so that the charging port of the smart watch can be placed at the third side wall 14 of the smart watch.

[0043] Since the charging port is arranged on the side of the smart watch, during charging, the charging head on the external charging cable 90 can be directly connected to the charging port at the third side wall 14 of the smart watch without removing the smart watch or flipping the smart watch, improving the charging convenience.

[0044] To make the charger head on the external charging cable 90 compatible with the charging port on the smart watch, the charger head on the external charging cable 90 includes a charger head housing, a charger head magnet, and charger head Pin pins. The charger head magnet and the charger head Pin pins are both disposed in the charger head housing. The charger head magnet is annular, and the charger head magnet is sleeved on the outer sides of the periphery of the charger head Pin pins. That is, the setting manners of the magnet and the Pin pins on the charger head are the same as those of the magnet and the Pin pins on the smart watch, so that the charger head can be adaptively connected to the charging port on the smart watch to realize charging for the smart watch.

[0045] When the charger head approaches the charging port on the smart watch, the charger head magnet on the charger head is attracted to the annular magnet on the smart watch, so that the charger head Pin pins on the charger head are connected to the charging Pin pins 30 on the smart watch to realize charging for the smart watch.

[0046] The smart watch further includes a pulse sensor 60, a photoelectric sensor 70, and a SIM card slot seat 80. The pulse sensor 60, the photoelectric sensor 70, and the SIM card slot seat 80 are respectively disposed on the bottom plate 11. The charging port of the smart watch is disposed on the side wall. There can be more space at the bottom of the smart watch to set more sensors, so that the sensors can be closely attached to the user's skin to measure more physiological parameters of the human body. For example, the heart rate is measured by the pulse sensor 60, and the PPG signal is obtained by the photoelectric sensor 70 to measure the blood oxygen value, blood pressure, respiratory rate, etc. to meet more usage requirements of the user.

[0047] The principle of measuring the blood oxygen value is as follows: Since there is a certain ratio between oxyhemoglobin HbO2 and hemoglobin Hb contained in the blood. And Hb has a higher light absorption coefficient for light with wavelengths between 600 and 800 nm, and HbO2 has a higher light absorption coefficient for light with wavelengths between 800 and 1000. Therefore, red light (600 - 800 nm) and light close to IR (800 - 1000 nm) can be used to respectively detect the PPG signals of HbO2 and Hb, and then the corresponding ratio is calculated through program processing, so that the blood oxygen value can be obtained.

[0048] The principle of the photoelectric sensor 70 for measuring blood pressure is: The change in blood volume is reflected through the PPG signal, and then the blood pressure is calculated by using the change in blood volume.

[0049] The principle of the photoelectric sensor 70 for measuring the respiratory rate is: The PPG sensor has a green LED or a red LED and an infrared LED. The light on the PPG sensor is alternately sent into the tissue (such as the skin in the ear canal). The photodiode receives the light that has been reflected by the tissue or not absorbed, and converts this information into an electric current. The electric current is converted into a voltage by a transimpedance amplifier and then digitized. Since respiration affects the changes in the blood volume in venous return and arterial blood pressure, the respiratory rate can be obtained from the measured PPG curve through frequency analysis.

[0050] In some embodiments, such as Figure 3 and Figure 4 shown, the two ends of the annular magnet 20 along the length direction of the watch band 40 have opposite magnetic poles. The length direction of the watch band 40 is the extending direction after the watch band 40 is unfolded, that is, the direction from the first side wall 12 to the second side wall 13 in Figure 1 . The annular magnet 20 is a single piece of magnet. When magnetized, one end of the annular magnet 20 can be magnetized as the N pole, and the other end of the annular magnet 20 can be magnetized as the S pole. The charging Pin needle 30 is located inside the annular magnet 20. Assuming that there are two charging Pin needles 30 for connecting to the charging head, then one charging Pin needle 30 is close to the N pole of the annular magnet 20, and the other charging Pin needle 30 is close to the S pole of the annular magnet 20.

[0051] Similarly, a magnet adapted to the annular magnet 20 on the smart watch is also provided on the charging head for charging the smart watch. The charging head magnet on the charging head is also annular, and the magnetic poles at both ends of the charging head magnet are also opposite. When charging, if the charging head is correctly connected to the charging port on the smart watch, then the N pole of the annular magnet 20 on the smart watch attracts the S pole on the charging head, and the S pole of the annular magnet 20 on the smart watch attracts the N pole on the charging head, which can make the charging Pin needle 30 on the smart watch correctly dock with the charging head Pin needle on the charging head; if the charging head is reversely connected to the charging port on the smart watch, the N pole of the annular magnet 20 on the smart watch will repel the N pole on the charging head, and the S pole of the annular magnet 20 on the smart watch will repel the S pole on the charging head, making it impossible to complete the docking of the charging head and the charging port on the smart watch, so as to remind the user to change the direction of the charging head and prevent the reverse insertion of the charging head and the charging port on the smart watch.

[0052] For the convenience of arranging the annular magnet 20 on the third side wall 14 and arranging the charging Pin needle 30 inside the annular magnet 20, the annular magnet 20 is strip-shaped, and the length of the annular magnet 20 along the length direction of the watch band 40 is greater than the length of the annular magnet 20 along the height direction of the smart watch. The annular magnet 20 extends along the width direction of the watch band 40, so as to facilitate arranging a plurality of charging Pin needles 30 along the width direction of the watch band 40 inside the annular magnet 20.

[0053] In some embodiments, such as Figure 1As shown in the figure, a charging slot 142 is provided in the outer wall of the third side wall 14 corresponding to the area of the annular magnet 20, and the end of the charging Pin 30 extends into the charging slot 142. The charging slot 142 on the outside of the third side wall 14 is adapted to the charging head of the external charging cable 90 for accommodating the charging head. During charging, the magnet on the charging head attracts the annular magnet 20 on the inner wall of the third side wall 14, so that the charging head enters the charging slot 142, and the charging head Pin on the charging head contacts the charging Pin 30 in the charging slot 142 to achieve charging.

[0054] Preferably, the opening area of the charging slot 142 is larger than the bottom area of the charging slot 142. By setting the charging slot 142 in a flared shape, after the charging head enters the charging slot 142, the position of the charging head can be adjusted through the charging slot 142, so that the charging head magnet on the charging head is precisely attracted to the annular magnet 20 on the back of the charging slot 142, and then the charging head Pin on the charging head is precisely docked with the charging Pin 30 in the charging slot 142, improving the docking accuracy between the charging head and the charging port of the smart watch.

[0055] Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 lies in the different structure of the annular magnet, and other structures are the same as those in Embodiment 1, so they will not be elaborated here. As Figure 5 shown in the figure, in this embodiment, the annular magnet 20 includes a first annular magnet 21 and a second annular magnet 22. The first annular magnet 21 is sleeved outside the second annular magnet 22. The two ends of the first annular magnet 21 in the width direction of the watch band 40 have opposite magnetic poles, the two ends of the second annular magnet 22 in the width direction of the watch band 40 have opposite magnetic poles, and the adjacent ends of the first annular magnet 21 and the second annular magnet 22 have opposite magnetic poles.

[0057] As Figure 5 shown in the figure, the left end of the first annular magnet 21 is the S pole, the right end is the N pole, the left end of the second annular magnet 22 is the N pole, and the right end is the S pole. After the first annular magnet 21 and the second annular magnet 22 are sleeved together, the left end of the first annular magnet 21 is attracted to the left end of the second annular magnet 22, and the right end of the first annular magnet 21 is attracted to the right end of the second annular magnet 22.

[0058] To ensure that the magnet on the charging head is adapted to the annular magnet 20 on the smart watch, the magnet on the charging head is also set as two annular magnets. The two annular magnets on the charging head are respectively the third annular magnet and the fourth annular magnet, and the magnetic pole distribution of the third annular magnet and the fourth annular magnet is opposite to the magnetic pole distribution of the two annular magnets on the smart watch, so that the two annular magnets on the charging head can be attracted to the two annular magnets on the smart watch one by one.

[0059] When the charging head is docked with the charging port on the smart watch, the third annular magnet on the charging head is attracted to the first annular magnet 21 on the smart watch, and the fourth annular magnet on the charging head is attracted to the second annular magnet 22 on the smart watch. By dividing the annular magnet 20 into multiple nested annular magnets, so that the multiple magnets are attracted to each other one by one, it is possible to prevent left and right displacement misalignment when the charging head is attracted and docked with the charging port, thereby improving the accuracy of the attraction and docking between the charging head and the charging port, eliminating the need for the user to make repeated adjustments, and enhancing the convenience of user use.

[0060] Embodiment Three

[0061] The difference between this embodiment and the above-mentioned Embodiment One or Two lies in the different setting positions of the charging port of the smart watch. In this embodiment, the charging port of the smart watch is set at the first side wall 12 connected to the strap 40 of the smart watch. The first side wall 12 can be a side wall close to the inner side of the wrist or a side wall close to the outer side of the wrist.

[0062] As Figure 6 shown, when charging, a small mobile power supply 50 can be directly used to charge the smart watch. A buckle structure can be set on the small mobile power supply 50. When the charging head on the small mobile power supply 50 is attracted to the charging port on the smart watch by a magnet and charges the smart watch, the buckle structure on the small mobile power supply 50 can be snapped onto the strap 40 of the smart watch to fix the small mobile power supply 50 on the smart watch, enabling the smart watch to be used normally during charging, without the user being located next to a power socket or holding the mobile power supply in hand, thus providing more convenient services for the user and enhancing the user experience.

[0063] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
