At the same time, as a product used close to the body, the battery endurance of the watchband equipment has also been criticized by society and has become a common knowledge.

[0003] The conventional design of such intelligent watchband electronic products is watchband type, and the charging position is on the back of the watch body, and has physiological monitoring functions such as heart rate. The charging methods of watchband type intelligent watchband equipment on the market are roughly divided into three categories: directly connecting the charging wire and inserting it into the charging socket of the watchband equipment; magnetic charging: the watchband equipment is attracted to the charger by magnetic attraction.

[0004] The disadvantages of the above charging methods are as follows: due to the limitation of the charging wire, the user's activity range is restricted. In addition, the watchband equipment needs to be removed during charging, and the physiological monitoring functions such as heart rate cannot be used.

[0005] After searching the prior art, the patent application number CN201720106576.5 "intelligent watchband equipment power bank and intelligent watchband equipment charged with the power bank" is obtained.

The utility model solves the problem that such watchband equipment can still be used when worn, but due to the structural design idea of the product, the difference in use and wearing method, it is not small, portable, and the use comfort is not good.

[0006] After continuous research and development, further, the patent application number 202122949578.X "a side clamping type mobile power source" is greatly improved, the function integration is high, the space is compact, small and portable, the application group is large, and the market demand is high. But from the size of the body, it still does not reach the standard of being able to integrate the protective shell characteristics of the watchband equipment, so the space layout still has a lot of optimization space.

DETAILED DESCRIPTION

[0054] The utility model will be explained in detail below in combination with specific embodiments. The following embodiments will help the person skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the utility model, a number of variations and improvements can be made. These all belong to the protection scope of the utility model.

[0055] The shell of the watchband device charger designed in the utility model is specially designed for watchband type electronic equipment, wherein the charging port is located on the back of the watch body, and the back of the watch body integrates physiological monitoring functions such as heart rate and blood oxygen (hereinafter referred to as "watchband equipment"). The structure diagram is shown in detail in Figure 8a 、 8b and 8c.

[0056] Based on the above-mentioned watchband equipment, in an embodiment of the utility model, a shell of a watchband equipment charger is provided, the shell 1 is used for clamping the watchband equipment, is located at the side of the watchband equipment and protects the side and bottom of the watchband equipment, and the shell 1 and the central area of the bottom of the watchband equipment are provided with a hollow area 5.

[0057] In order to further improve the space configuration efficiency of the shell, so that it meets the integration requirement as a watchband equipment protective shell, in a preferred embodiment of the utility model, a preferred structure of the shell is provided, as shown in Figure 2a andFigure 2b The shell includes a main body 101, side holders 102, a bottom holder 104 and connecting members 106.

[0058] The main body 1 is used to mount the electronic components required by the charger, which generally include a circuit board 4 and a charging input 3 (the charging input 3 is connected to the circuit board); the side holders 102 are connected to the two sides of the main body, and form an open frame-shaped accommodating space after being connected. For example, as shown in Figure 2a and Figure 2b The two side holders 102 are connected to the main body 101 at the same angle, which can be set according to requirements, such as a right angle, or an acute or obtuse angle close to a right angle, mainly to accommodate / hold the watchband device. Preferably, as shown in the figure, the two side holders 102 and the main body 101 form an open frame-shaped accommodating space after being connected, that is, a "clamping type" similar to the shape of the Chinese character "Fang", in which the two parallel sides correspond to the two side holders 102, and the vertical side in the middle corresponds to the main body 101. The bottom holder 104 is arranged at the middle position of the two side holders 102 and the main body 101, that is, at the middle position of the accommodating space formed by them. The charging output 2 of the charger is mounted at the bottom holder 104; the two connecting members 106 extend outward from the edges of the bottom holder until the main body, the side holder or the junction of the main body and the side holder; the main body, the connecting member and the bottom holder enclose a hollow area 5.

[0059] In some embodiments, the main body 101 is a cavity structure, which not only can reduce the weight and material cost of the entire clamping shell, but also can place the circuit board 4 inside the main body 101, saving space. Further, one side surface of the frame-shaped accommodating space formed by the two side holders 102 and the main body 101 is located on the same horizontal plane as the outer side surface of the bottom holder 104, that is, according to Figure 4 as shown, the bottom holder 104 is located at the middle position of the accommodating space and on the plane where the lower surface of the accommodating space is located. The shape of the accommodating space is adapted to the shape of the watchband device. Preferably, the pipe diameters of the main body and the side holder can be designed to be the same.

[0060] In some embodiments, one end of the connecting member 106 is connected to the edge of the bottom holder 104, and the other end is connected to the junction of the main body 101 and the side holder 102, as shown in Figure 2a and Figure 2b to form a hollow area 5. In this embodiment, the wearing effect of the part without the hollow area is compared with the wearing effect of the part with the hollow area, as shown in Figure 3a which shows the wearing effect of the part without the hollow area, and Figure 3b which shows the wearing effect of the part with the hollow area. Through comparison, it can be clearly seen that the part without the hollow area is Figure 3aIn the case of a large thickness, such a design can cause the overall inclination of the shell and the watch band device when worn together. However, in the case of Figure 3b , by ingeniously designing the hollowed-out area, the overall inclination phenomenon is effectively avoided, thereby significantly improving the comfort of wearing.

[0061] In some embodiments, in order to increase protection, the surface of the charging output end 2 and the circuit board 4 contains or integrates a shell cover plate.

[0062] The shell structure in the above embodiment can form a perfect match with the watch band device. Compared with the side clip type power bank with application number 202122949578.X, its significant feature is that the side support bottom is designed simply without redundant branch structure, and ingeniously integrates the hollow design. This innovative measure significantly reduces the overall volume of the shell, making it more compact, and the characteristics of the watch band device protective shell are complementary, achieving a more harmonious combination.

[0063] The specific shape and structure of the main body and the side support are not the only limitation, that is, they can be adapted and attached to the watch band device. Therefore, in some embodiments, the outer shape of the main body 101 and the side support 102 needs to be designed according to the size data of the installed watch band device, so that after the watch band device is installed, 101 and 102 are completely attached to the side of the watch band device.

[0064] In order to make the shell more stable with the watch band device, in a preferred embodiment of the present application, the end of the side support 102 is provided with a bent corner wrapped and bent towards the bottom support for auxiliary fixation, and a round corner for the easy entry and exit of the watch band, as shown in Figure 5b . Figure 5a The structure design before the optimization of the bent corner and the round corner.

[0065] In order to optimize the connection effect of the shell and the watch band device, in a preferred embodiment of the present application, a through hole is designed in the center of the bottom support, forming a ring structure, which is coupled or attached to the charging receiving end of the watch band device. This ring structure can tightly fit or attach to the charging receiving end of the watch band device. At the same time, the through hole is used for the physiological monitoring sensor on the watch body device to detect the skin of the human body through the through hole to detect the related physiological data.

[0066] In some specific embodiments, the size of the bottom support is designed according to the shape and size parameters of the back of the watch band device, so that the bottom support can perfectly attach to the back of the watch band device (including the convex part). The size design ensures that the reserved through hole can make the sensor directly contact with the skin, thereby ensuring that the heart rate, blood oxygen and other physiological monitoring functions of the bottom of the watch band device can be normally used, as shown in Figure 6a , Figure 6b and Figure 6cAs shown.

[0067] like Figure 1a As shown, in a preferred embodiment of this utility model, a transparent shell 105 is designed, which connects to and covers the area enclosed by the main body 101 and the side support 102. In some specific embodiments, the edges of the transparent shell are connected to the main body and the side support by adhesive. Of course, the transparent shell 105 is not necessary and can be removed, such as... Figure 7a and Figure 7b As shown, the side support 102 fits against the front of the watch strap, and the housing can still be fixed to the watch body of the watch strap device. In some specific embodiments, the transparent housing uses tempered glass.

[0068] In a preferred embodiment of this invention, the housing is made of an elastic material, such as PE, ABS, PA, POM, etc. The housing is made of an elastic material so that it can deform within a certain range when the watch strap device is inserted, and then elastically return to its original position when the watch strap device is correctly inserted.

[0069] Based on the same concept, in another embodiment of the present invention, a watch strap device charger is provided, including a charging input terminal, a circuit board and a charging output terminal, and further including a housing, which is any of the housings in the above embodiments.

[0070] In a preferred embodiment, the circuit board 4 and the charging input terminal 3 are mounted on the main body 101 of the housing, and the charging output terminal 2 is mounted on the bottom of the housing. The charging input terminal 3 is used to connect to an external power source to obtain electrical energy; the circuit board 4 processes the electrical energy obtained by the charging input terminal and converts it into electrical energy suitable for the watchband device; the charging output terminal 2 delivers the converted electrical energy to the watchband device for charging. This design concentrates the circuit structure on one side of the main body of the housing, optimizes the housing structure, effectively reduces the product size, and enables charging of the watchband device through a unique side clip (side buckle). The optimized product size, due to its compact nature, integrates the protective housing characteristics of the watchband device.

[0071] In a preferred embodiment of this utility model, the charging output terminal is selected as a wireless charging terminal or a contact / plug charging terminal.

[0072] When selecting a wireless charging terminal, a conductor coil and a magnetic shielding structure are used. This charging method and structure are existing technologies. Specifically, the base can contain a magnetic shielding body and a conductor coil that releases wireless charging energy.

[0073] When the contact / jack type charging end is selected, the internal structure of the charging output end 2 is only a conductor and a shell, and the charging output end can be designed as a ring-shaped structure, and a contact or a plug base is arranged at the ring-shaped structure to contact and fit with the watch band equipment charging port. The charging is realized by connecting the wire 9 in the watch band equipment to the circuit board.

[0074] When the watch band equipment is charged by using the shell of the watch band equipment charger in the above embodiment, the shell wraps the watch band equipment from the side, the external power supply (power adapter or charger) is connected through the charging input end 3, the alternating current is converted into direct current through the circuit board 4, and the electric energy is transmitted to the charging output end to supply the watch band equipment.

[0075] When the watch band equipment is charged by using the shell of the watch band equipment charger in the above embodiment, the shell wraps the watch band equipment from the side, the external power supply (power adapter or charger) is connected through the charging input end 3, the alternating current is converted into direct current through the circuit board 4, and the electric energy is transmitted to the charging output end to supply the watch band equipment.

[0076] The shell of the watch band equipment charger in the above embodiment can be perfectly integrated with the watch band equipment, and the user can wear it on the wrist, which does not affect the normal use of the watch band equipment and can realize convenient charging function. The unique hollow design not only optimizes the wearing experience but also improves the overall comfort.

[0077] Based on the same inventive concept, in other embodiments of the utility model, a mobile power supply is provided, which comprises a power supply part and any one of the shells in the above embodiments, and the power supply part is installed or integrated in the shell to provide electric energy for the watch band equipment held by the shell.

[0078] Further, in a preferred embodiment, as shown in Figure 4 The detachable structure comprises an energy storage battery and a control board, and the energy storage battery is connected with the control board. The energy storage battery, the control board and part of the shell structure are equivalent to be separated out as the power supply part 6 and be charged separately. The design can make the structure of the main body 101 smaller and lighter.

[0079] In the case where the power supply part 6 is not installed, an external power supply (adapter or power bank) can be used to supply power to the shell through the charging input end, the circuit board and the charging output end, so as to charge the watch band equipment.

[0080] When the detachable part of the main body is installed back, that is, when the power supply part 6 is connected, the electric energy of the energy storage battery can be directly used to charge the watch band equipment. In addition, in some other embodiments, when the external power supply is connected at the same time, the power supply part and the watch band equipment can be charged at the same time.

[0081] In some embodiments, the power supply 6 is protected by a cover plate that is attached to the housing.

[0082] In the above embodiments, the power supply is integrated into the housing to form a power bank, so that the user can wear the watch device normally and move freely when charging the watch device.

[0083] To ensure a clear and comprehensive understanding of the structure and function of the watch device charger, the housing, and the power bank involved in the present application, the following will elaborate on the use process.

[0084] As shown in Figure 8a , 8b , 8c, Figure 9a , Figure 9b , Figure 9c , Figure 10a and Figure 10b , the use process of the housing of the watch device charger without a transparent shell is as follows:

[0085] Insert the housing from the side of the watch device. Specifically, as shown in Figure 9a , insert the bottom support 104 between the watch device and the skin;

[0086] Because of the pressure from the watch device, the bottom support 104 and the side support 102 bend outward, as shown in Figure 9b ;

[0087] Until the bottom support 104 is fully inserted and fully adheres to the back of the watch device, at which point the bottom support 104 and the side support 102 rebound inward, fixing or clamping the watch body, as shown in Figure 9c ,

[0088] At this point, the side of the watch body X (the side in the x-axis direction) adheres to the main body 101 and the side support 102, or the edge of the watch band side of the watch device adheres to the connecting piece 106, and the bottom support 104 fully adheres to the protrusion at the bottom of the watch device, so that the watch device is fixed in the X\Y\Z axes, as shown in Figure 10a and Figure 10b .

[0089] As shown in Figure 8a , 8b , 8c, Figure 9a , Figure 9b , Figure 9c , Figure 10a and Figure 10b , the use process of the housing of the watch device charger with a transparent shell is as follows:

[0090] As shown in Figure 9a , Figure 9b , Figure 9cAs shown, by the way of side insertion of the watchband device, the transparent shell 105 is in contact with the watchband device dial, the bottom support 104 is in contact with the back of the watchband device, and the measuring support 102 is in contact with the watchband of the watchband device. Figure 10b As shown.

[0091] During the process of insertion of the bottom support 104 between the watchband device and the skin, the bottom support 104 is bent outwardly and opened together with the side support 102 and the transparent shell 105 due to the extrusion of the watchband device;

[0092] Until the bottom support 104 is completely inserted and completely adheres to the back of the watchband device, at this time, the bottom support 104 is rebounded inwardly together with the side support 102 and the transparent shell 105, and the connecting piece 106 is in contact with the side edge of the watchband of the watchband device, as shown in Figure 10a , so as to fix or clamp the watch body of the watchband device.

[0093] At this time, under the action of 102, 102, 104, 105, 106, through physical analysis, it can be known that the watchband device is effectively fixed.

[0094] Under the premise of ensuring that the watchband device is closely fixed with the shell, the charging process of the watchband device can be started. There are three charging ways, one is to directly connect the alternating current power through the charging input port to provide stable charging service for the watchband device; the second is to connect the power bank or other energy storage power supply through the charging input port to continuously supply power for the watchband device; the third is to rely on the self-contained charging of the detachable battery part carried by the watchband device.
