[0044] The present application is described in detail below through specific embodiments:

[0045] See also Figure 1 and Figure 2The embodiment of the present application provides a smart watch 100, which includes a host 110, the host 110 includes a host housing 111, a host charging component 112 and a first magnetic member 113, the host charging component 112 is arranged on the first side wall 1111 of the host housing 111, the host charging component 112 includes a first host charging pin needle group 1121, a second host charging pin needle group 1122 and a third host charging pin needle group 1123 arranged at equal intervals along a first straight line, the first host charging pin needle group 1121 and the third host charging pin needle group 1123 have the same electrical polarity, and the first host charging pin needle group 1121 and the second host charging pin needle group 1122 have opposite electrical polarities; the first magnetic member 113 is installed on the first side wall 1111, and the surface of the first magnetic member 113 facing the outside of the host housing 111 is the same magnetic pole surface.

[0046] The smart watch 100 is one of the smart wearable devices. Of course, other smart wearable devices such as phone watches, smart bracelets, etc. are applicable to the above structure. The first side wall 1111 refers to one of the side walls of the housing of the host 110. For example, the side wall of the housing of the host 110 includes four side walls connected in sequence, and the first side wall 1111 refers to any one of the four side walls.

[0047] In addition, the above-mentioned first magnetic component 113 includes but is not limited to magnets, magnets, etc., and the surface of the first magnetic component 113 facing the outside of the main body shell 111 is the same magnetic pole surface. It should be understood that the magnetic poles of the surface of the first magnetic component 113 facing the outside of the main body shell 111 are the same, for example, the magnetic pole of the surface of the first magnetic component 113 facing the outside of the main body shell 111 is the N pole, or the magnetic pole of the surface of the first magnetic component 113 facing the outside of the main body shell 111 is the S pole.

[0048] In addition, see Figure 2 and Figure 3The number of the first charging pin pins 112a in the above-mentioned first host charging pin pin group 1121 can be one, or two or more. Similarly, the number of the second charging pin pins 112b in the second host charging pin pin group 1122 can be one, or two or more. The number of the third charging pin pins 112c in the third host charging pin pin group 1123 can be one, or two or more. Furthermore, the electrical polarity of the first host charging pin group 1121 and the third host charging pin group 1123 is the same, and the electrical polarity of the first host charging pin group 1121 and the second host charging pin group 1122 is opposite. It should be understood that the first charging pin 112a in the first host charging pin group 1121 and the third charging pin 112c in the third host charging pin group 1123 have the same electrode, for example, both are positive electrodes, then the electrode of the second charging pin 112b in the second host charging pin group 1122 is a negative electrode, that is, whether the charging head 120 is connected to the first charging pin 112a and the second charging pin 112b for charging or the charging head 120 is connected to the third charging pin 112c and the second charging pin 112b for charging.

[0049] Therefore, in this embodiment, since the first host charging pin needle group 1121, the second host charging pin needle group 1122 and the third host charging pin needle group 1123 are arranged at equal intervals along the first straight line, the electrical polarity of the first host charging pin needle group 1121 and the third host charging pin needle group 1123 is the same, and the electrical polarity of the first host charging pin needle group 1121 and the second host charging pin needle group 1122 is opposite. Therefore, when the charging head 120 charges the host 110, the charging head 120 can cooperate with the first host charging pin needle group 1121 and the second host charging pin needle group 1122 for charging, or the charging head 120 can also cooperate with the third host charging pin needle group 1123 and the second host charging pin needle group 1122 for charging. Since the positive and negative poles of the charging head 120 are fixed, when the charging head 120 and the first host charging pin needle group 112 1 and the second host charging pin needle group 1122 are matched, and the posture of the charging head 120 when cooperating with the third host charging pin needle group 1123 and the second host charging pin needle group 1122 is different. That is to say, when the charging head 120 cooperates with the first host charging pin needle group 1121 and the second host charging pin needle group 1122, the charging head 120 faces the first direction, and when the charging head 120 cooperates with the third host charging pin needle group 1123 and the second host charging pin needle group 1122, the charging head 120 faces the second direction opposite to the first direction. Because the surface of the first magnetic member 113 installed on the first side wall 1111 facing the outside of the host housing 111 is the same magnetic pole surface, therefore, no matter whether the charging head 120 faces the first direction or the second direction, there is no fool-proof setting, thereby improving the flexibility of the charging head 120 to charge the host 110, thereby improving the charging experience of the user.

[0050] In addition, since the surface of the first magnetic component 113 facing the outside of the host housing 111 is the same magnetic pole surface (for example, the S pole in 4), the manufacturing difficulty of the first magnetic component 113 is simplified compared to setting two opposite magnetic pole surfaces on the surface of the first magnetic component 113 facing the outside of the host housing 111.

[0051] In some possible embodiments, see Figure 3The first host charging pin needle group 1121 includes multiple first charging pin needles 112a, the second host charging pin needle group 1122 includes multiple second charging pin needles 112b, and the third host charging pin needle group 1123 includes multiple third charging pin needles 112c. The multiple first charging pin needles 112a, the multiple second charging pin needles 112b, and the multiple third charging pin needles 112c all correspond to each other, and the multiple first charging pin needles 112a, the multiple second charging pin needles 112b, and the multiple third charging pin needles 112c are all distributed along the second straight line at intervals, and the second straight line is perpendicular to the first straight line.

[0052] Therefore, by making the first charging pin 112a, the second charging pin 112b and the third charging pin 112c multiple and distributed along the second straight line, the diversity of charging combinations of the charging head 120 and the first host charging pin group 1121, the second host charging pin group 1122 and the third host charging pin group 1123 can be further improved, thereby further improving the charging flexibility of the host 110.

[0053] The above-mentioned multiple refers to a number of two or more, for example Figure 3 As shown, there are two first charging pin 112a, two second charging pin 112b and two third charging pin 112c.

[0054] In some possible embodiments, see Figure 2 and Figure 4 The first magnetic member 113 defines a first avoidance hole 1131 , and the first host charging pin group 1121 , the second host charging pin group 1122 , and the third host charging pin group 1123 are all located in the first avoidance hole 1131 .

[0055] Therefore, by setting the first avoidance hole 1131 on the first magnetic member 113, and making the first host charging pin needle group 1121, the second host charging pin needle group 1122 and the third host charging pin needle group 1123 all located in the first avoidance hole 1131, on the one hand, when the charging head 120 charges the host 110, the stability of the magnetic fixation between the charging head 120 and the host 110 can be ensured, and on the other hand, the compactness of the structural setting between the first magnetic member 113 and the host charging component 112 is improved.

[0056] In addition, the first avoidance hole 1131 is a through hole, but the shape of the first avoidance hole 1131 is not limited. For example, the shape of the first avoidance hole 1131 is circular, rectangular, elliptical, etc.

[0057] In some possible embodiments, see Figure 4 and Figure 5 A mounting groove 1112 is provided on the first side wall 1111 , and the first magnetic member 113 is installed in the mounting groove 1112 .

[0058] Specifically, a mounting groove 1112 is provided on a surface of the first side wall 1111 facing the inner space of the main housing 111 , and the shape and size of the mounting groove 1112 correspond to the shape and size of the first magnetic member 113 .

[0059] Therefore, by providing a mounting groove 1112 on the first side wall 1111 to mount the first magnetic component 113 , the compactness of the structure between the first magnetic component 113 and the first side wall 1111 can be improved, thereby making the smart watch 100 conform to a compact design.

[0060] In some possible embodiments, see Figure 3 The distance between the first host charging pin group 1121 and the second host charging pin group 1122 is between 2.5 mm and 3 mm.

[0061] The above 2.5 mm to 3 mm refers to the distance range between the first charging pin 112a in the first host charging pin group 1121 and the second charging pin 112b in the second host charging pin group 1122 in the extending direction of the first straight line, that is, Figure 3 The distance represented by D in FIG. For example, the distance between the two includes but is not limited to 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, etc.

[0062] Therefore, by making the spacing between the first host charging pin needle group 1121 and the second host charging pin needle group 1122 between 2.5mm and 3mm, on the one hand, it can avoid the difficulty of assembly between the two due to the spacing between the two being too small, and on the other hand, it can avoid the situation where charging short circuit is easily caused when the charging head 120 is offset due to the spacing between the two being too large.

[0063] In some possible embodiments, the first host charging pin group 1121 , the second host charging pin group 1122 , and the third host charging pin group 1123 are all made of titanium alloy.

[0064] Since titanium alloy has the advantages of high strength, low density, good mechanical properties, and good corrosion resistance, when the materials of the first host charging pin needle group 1121, the second host charging pin needle group 1122, and the third host charging pin needle group 1123 are all made of titanium alloy, the possibility of electrochemical corrosion of the host charging component 112 can be greatly reduced.

[0065] In some possible embodiments, see Figure 6 , Figure 7 and Figure 8 The smart watch 100 also includes a charging head 120, which includes a charging head housing 121, two charging head pin needles 122 and a second magnetic member 123, wherein the two charging head pin needles 122 are arranged at intervals and have opposite electrodes, the two charging head pin needles 122 are arranged in the charging head housing 121, and the ends of the two charging head pin needles 122 extend out of the charging head housing 121; the second magnetic member 123 is arranged in the charging head housing 121, and when the second magnetic member 123 is adsorbed and fixed to the first magnetic member 113, the two charging head pin needles 122 are respectively connected to the first charging pin needle 112a and the second charging pin needle 112b, or are connected to the third charging pin needle 112c and the second charging pin needle 112b.

[0066] The surface to which the second magnetic member 123 and the first magnetic member 113 are adsorbed is the same magnetic pole surface, and the magnetism is opposite to the magnetism of the surface of the first magnetic member 113 facing the second magnetic member 123 .

[0067] In addition, one of the two charging head pin pins 122 is a positive charging head pin pin, and the other is a negative charging head pin pin.

[0068] For example, the first charging pin 112a and the third charging pin 112c are both positive poles, and the second charging pin 112b is a negative pole. Then, when the charging head 120 charges the host 110, the positive charging head pin can be connected to the first charging pin 112a or the third charging pin 112c, while the negative charging head pin can only be connected to the second charging pin 112b.

[0069] Therefore, by connecting the two charging head pin pins 122 to the first charging pin pin 112a and the second charging pin pin 112b respectively, or connecting to the third charging pin pin 112c and the second charging pin pin 112b, the charging head 120 can charge the host 110 in a variety of postures, rather than only being able to charge the host 110 in a specific posture, thereby improving the charging flexibility of the charging head 120 and the user experience.

[0070] In some possible embodiments, see Fig. 9 The second magnetic member 123 is provided with a second avoidance hole 1231 , and the two charging head pins 122 are located in the second avoidance hole 1231 .

[0071] By setting a second avoidance hole 1231 on the second magnetic part 123, and the two charging head pin needles 122 are located in the second avoidance hole 1231, on the one hand, the effective magnetic attraction area between the first magnetic part 113 and the second magnetic part 123 can be guaranteed, so as to ensure the stability of the electrical connection between the two charging head pin needles 122 and the host charging component 112 when the charging head 120 charges the host 110; on the other hand, the structural compactness between the two charging head pin needles 122 and the second magnetic part 123 can be improved, so that the charging head 120 conforms to the compact design.

[0072] In some possible embodiments, see Fig.10 A limiting convex ring 1113 is provided on the first side wall 1111, and the limiting convex ring 1113 is arranged around the first host charging pin needle group 1121, the second host charging pin needle group 1122 and the third host charging pin needle group 1123; the end of the second magnetic member 123 extends out of the shell, and when the second magnetic member 123 is adsorbed and fixed to the first magnetic member 113, the end of the second magnetic member 123 cooperates with the limiting convex ring 1113.

[0073] Therefore, by setting a limiting convex ring 1113 on the first side wall 1111, and when the second magnetic part 123 is adsorbed and fixed to the first magnetic part 113, the end of the second magnetic part 123 cooperates with the limiting convex ring 1113. On the one hand, when the charging head 120 charges the host 110, the charging head 120 is prevented from being offset relative to the first side wall 1111, thereby ensuring the charging effect of the host 110. On the other hand, when the charging head 120 charges the host 110 in different postures, the limiting convex ring 1113 limits the end of the second magnetic part 123, thereby avoiding the occurrence of a charging short circuit between the charging head 120 and the host 110.

[0074] In some possible embodiments, see Figure 8 The ends of the two charging head pins 122 are flush with or lower than the end surface of the second magnetic member 123 extending out of the charging head housing.

[0075] Among them, the ends of the two charging head pin needles 122 are lower than the end surface of the second magnetic part 123 extending out of the charging head housing, which means that the ends of the two charging head pin needles 122 do not extend out of the second avoidance hole 1231 on the second magnetic part 123, that is to say, the ends of the two charging head pin needles 122 are located in the second avoidance hole 1231.

[0076] Therefore, by making the ends of the two charging head pin needles 122 flush with or lower than the end surface of the second magnetic part 123 extending out of the charging head shell, the distance between the charging head 120 and the host 110 can be shortened when the charging head 120 charges the host 110, thereby ensuring the stability of the charging of the host 110 by the charging head 120.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
