In the embodiment of the present application, the wearable device 100 is a smart watch, the main body 110 is a watch face, and the wearing portion 130 is a watch band. The main body 110 is a component for realizing daily display and interaction of the wearable device 100, and the wearing part 130 is used for relatively fixing the main body 110 and a user, so as to realize a wearing effect of the wearable device 100.

The display panel may be a touch display panel, and the display panel, the frame 113 and the middle frame plate 111 are sequentially connected to form an accommodating space in which the electronic component is accommodated.

The electronic element is electrically connected to the display panel to implement the related functions of the wearable device 100. The detailed structure of the electronic device and the display panel is not described herein.
The middle frame plate 111 may have a plate-like or sheet-like structure. Optionally, the middle frame plate 111 is provided with a hole or a groove for mounting electronic components of the wearable device 100. For example, electronic components such as sensors and a central processor of the wearable device 100 may be mounted to the bezel 111 through holes or slots. In the embodiment of the present invention, the middle frame plate 111 may be made of a metal material such as aluminum alloy and stainless steel, or an electrically insulating material such as ceramic and glass.
In the present embodiment, the frame 113 has a substantially strip shape, and the frame 113 is connected to the edge of the middle frame plate 111 and substantially forms a frame-shaped supporting structure. The frame 113 is substantially perpendicular to the middle frame plate 111, and forms a receiving space together with the middle frame plate 111, where the receiving space is used for receiving electronic components of the wearable device 100. The frame 113 is used to form a side frame of the main body 110. It should be understood that the side frame of the wearable device 100 refers to a side portion of the wearable device 100 in the thickness direction, and the side frame forms an appearance of the wearable device 100 together with a rear side surface (e.g., a rear cover) and a front side surface (e.g., a display panel) of the wearable device 100. The side frame of the wearable device 100 may be an integral structure with the front side surface, an integral structure with the back side surface, or a separate side frame, and the specific structure form is not limited herein.
Further, referring to fig. 2, the frame 113 is a substantially rectangular frame, and the first frame 1131 and the second frame 1133 are two opposite sides of the rectangle. The frame 113 further includes a third frame 1135 and a fourth frame 1137, where the third frame 1135 and the fourth frame 1137 are disposed opposite to each other and are connected between the first frame 1131 and the second frame 1133. In other words, the first frame 1131, the third frame 1135, the second frame 1133, and the fourth frame 1137 are connected in this order to form the bezel 113. Alternatively, the frame 113 may be a ring frame with other shapes, such as a circular frame. The first frame 1131, the third frame 1135, the second frame 1133, and the fourth frame 1137 are only defined to show the relative positions of the frames, and the specific structure of the frame 113 is not specifically limited.
In the embodiment of the present application, the first radiator 115 is a slot antenna. Specifically, the bezel 113 is made of a conductive material, such as an aluminum alloy, stainless steel, titanium alloy, conductive ceramic, or the like. The first frame 1131 and the middle frame 111 are spaced apart to form a first spacing gap 1123, the first frame 1131 is penetratingly provided with a first through gap 1121, and the first spacing gap 1123 is communicated with the first through gap 1121 to form the first radiator 115 on the first frame 1131. Specifically, the first through slit 1121 causes the first frame body 1131 to substantially form a first portion and a second portion spaced apart from each other, the first spacing slit 1123 is located between the middle frame plate 111 and the first portion of the first frame body 1131, and the first through slit 1121 communicates with the first spacing slit 1123 such that the first portion of the first frame body 1131 forms the first radiator 115 substantially independent from the middle frame plate 111. Wherein a length dimension of the first spacing slot 1123 is substantially equal to a length dimension of the first radiator 115. It should be noted that the first radiator 115 for receiving and transmitting the Wi-Fi signal can be formed by using the first frame 1131 and the first slit 112, which reduces the number of additional radiator steps in the wearable device 100 and reduces the production cost of the wearable device 100.
In some embodiments, there may be two first through slits 1121, and two first through slits 1121 are disposed at an interval on the first frame 1131, so that the first radiator 115 is located between the two first through slits 1121. The two first through slits 1121 are respectively communicated with both ends of the first spacing slit 1123. It should be noted that the above-mentioned first and second parts are only for convenience of description and are not limiting; and the slot widths in the figures are merely schematic widths and do not represent the widths of actual slots.
In the embodiment of the present application, the second radiator 117 is also a slot antenna. The second frame 1133 and the middle frame 111 are spaced apart from each other to form a second gap 1143, the second frame 1133 is provided with a second through gap 1141, and the second gap 1143 is communicated with the second through gap 1141, so as to form the second radiator 117 on the second frame 1133. Specifically, the second through slit 1141 substantially forms the second frame 1133 into a first portion and a second portion spaced apart from each other, the second separation slit 1143 is located between the middle frame plate 111 and the first portion of the second frame 1133, and the second through slit 1141 communicates with the second separation slit 1143, so that the first portion of the second frame 1133 forms the second radiator 117 substantially independent from the middle frame plate 111. The length of the second spacing gap 1143 is substantially the same as the length of the second radiator 117. It should be noted that the second radiator 117 for transceiving long term evolution signals can be formed by using the second frame 1133 and the second slot 114, which reduces the number of additional radiator steps in the wearable device 100 and reduces the production cost of the wearable device 100.
In some embodiments, there may be two second through slots 1141, and two second through slots 1141 are spaced apart from each other and disposed on the second frame 1133, so that the second radiator 117 is located between the two second through slots 1141. The two second through slits 1141 are respectively connected to two ends of the second separation slit 1143. It should be noted that the second radiator 117 is used for transceiving long term evolution signals, since the length of the antenna is inversely proportional to the frequency that the antenna can transceive, and the frequency band of the long term evolution signals is shorter than the frequency band of the Wi-Fi signals. The length dimension of the second radiator 117 is greater than the length dimension of the first radiator 115, that is, the length dimension of the second spacing gap 1143 is greater than the length dimension of the first spacing gap 1123.
Optionally, an insulating material may be disposed between the first slot 112 and the second slot 114 to enhance the connection structural strength of the first radiator 115 and the middle frame plate 111 and the connection structural strength of the second radiator 117 and the middle frame plate 111, thereby enhancing the overall strength of the first radiator 115 and the second radiator 117. The filled insulating material can be plastic, rubber, plastic, etc.
In the embodiment of the present invention, the first radiator 115 and the second radiator 117 are independently disposed and respectively disposed on the first frame 1131 and the second frame 1133, so that the radiation isolation between the first radiator 115 and the second radiator 117 can be improved, and further, the first radiator 115 and the second radiator 117 are prevented from interfering with each other during operation. It should be noted that the first radiator 115 and the second radiator 117 for transceiving signals of different frequency bands can be formed only by the frame 113, the first slot 112, and the second slot 114, which reduces the process of additionally arranging radiators on the wearable device 100 and reduces the production cost of the wearable device 100. Alternatively, the first radiator 115 and the second radiator 117 may be formed or connected to the first frame 1131 and the second frame 1133 by using a Laser Direct Structuring (LDS) technology, a Direct Printing (PDS) technology, a Flexible printed circuit (Flexible printed circuit) technology, and the like, which is not described herein again.
Referring to fig. 3, the wearing portion 130 can be detachably connected to the main body portion 110 by magnetic attraction, a snap structure, and the like. One end of the wearing portion 130 is connected to the third frame 1135, and optionally, the other end of the wearing portion 130 is connected to the fourth frame 1137 to form a substantially ring shape, and further fixed to a wearing part (e.g., a wrist) of a user through the ring shape. Alternatively, there are two wearing portions 130, the two wearing portions 130 are respectively connected to the third frame 1135 and the fourth frame 1137, and the two wearing portions 130 are connected to each other to form a ring shape, and are further fixed to the arm of the user through the ring shape. When the wearing unit 130 is connected to the first housing 1131 or the second housing 1133, interference is caused to the first radiator 115 disposed in the first housing 1131 or the second radiator 117 disposed in the second housing 1133, and signal transmission and reception of the first radiator 115 or the second radiator 117 is affected. Therefore, by connecting the wearing portion 130 to the third housing 1135, the normal operation of the first radiator 115 and the second radiator 117 can be ensured.
Further, the wearing portion 130 has a receiving groove 133, a conductive contact (not shown) is disposed in the receiving groove 133, and the third radiator 131 is detachably received in the receiving groove 133 and electrically connected to the conductive contact so as to be electrically connected thereto through the conductive contact. The third radiator 131 is an antenna module capable of receiving and transmitting 5G signals, and can be detached and replaced relative to the accommodating groove 133, so as to facilitate maintenance and replacement. The conductive contact may be connected to an electronic component (e.g., a circuit board, a power feeding unit, etc.) in the body portion 110 through a wire or the like, so as to control the operation of the third radiator 131 through the body portion 110. It should be noted that, because the third radiator 131 is disposed on the wearing portion 130, and is spaced far from the first radiator 115 and the second radiator 117 disposed on the body portion 110, and the first radiator 11, the second radiator 117, and the third radiator 131 are disposed independently of each other, the radiation isolation between the third radiator 131 and the first radiator 115 and the second radiator 117 may be improved, so as to avoid mutual interference between the first radiator 115, the second radiator 117, and the third radiator 131 during operation.
Optionally, the third radiator 131 includes a plurality of millimeter wave antenna units, and the plurality of millimeter wave antenna units are arranged on the surface of the wearing portion 130 in an array. Wherein, millimeter wave antenna element can be patch antenna, laminates in the surface of wearing portion 130, and a plurality of patch antennas are the array and arrange. The millimeter wave antenna unit may also be a slot antenna, a slot is formed on the surface of the wearing portion 130, and the plurality of slot antennas are arranged in an array. Further, the wearing portion 130 may be made of a non-metal material embedded with a metal material, such as a non-metal material like rubber or plastic material, and the millimeter wave array is formed by slitting or pasting the metal material portion of the wearing portion 130. It can be understood that when the user wears the wearable device 100, the non-metallic wearing portion 130 contacts with the user, so that the user can feel better.
