Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and particularly to a side glue - dotting structure of a wearable device and a wearable device. Background Art

[0002] Currently, most smart wearable devices have a relatively large screen FPC (Flexible Printed Circuit, abbreviated as FPC). In daily use scenarios, water may enter the interior of the housing through the gap between the cover plate and the housing, causing damage to the screen FPC and other electronic components. To achieve the waterproof function, it is necessary to perform waterproof treatment between the cover plate and the device housing. The traditional treatment method is to use glue to bond the housing and the cover plate, and by extending the lateral length of the glue application, the purpose of waterproof sealing is achieved.

[0003] However, such a sealing structure will result in a relatively large lateral diameter of the entire wearable device. The larger size will bring inconvenience in daily use, and even due to the larger size, it will bring greater weight, resulting in fatigue when the user wears the device for a long time. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems in the related art to some extent.

[0005] To achieve the above - mentioned purpose, the present invention provides a side glue - dotting structure of a wearable device, including a first housing. An accommodation cavity is arranged inside the first housing, and a screen FPC is arranged in the accommodation cavity. A second housing is detachably and fixedly connected to the outside of the first housing. The height of the top end face of the first housing is set lower than the height of the top end face of the second housing. A glue - applying annular groove is formed by surrounding the first housing and the second housing. A thickened glue layer is arranged in the glue - applying annular groove. The length of the thickened glue layer perpendicular to the end face of the first housing is greater than the length of the thickened glue layer parallel to the end face of the first housing. A cover plate is arranged above the thickened glue layer.

[0006] The present invention changes the traditional glue - dotting method. By setting a thickened glue layer, the thickness of the glue layer is increased to ensure the waterproof effect, and then the lateral distribution length of the glue is reduced to reduce the lateral diameter of the entire wearable device. The entire outer housing can be adaptively processed and designed according to the reduced diameter. After the entire housing is divided into a first housing and a second housing, the lateral diameter of the device can be reduced without affecting the waterproof effect, so as to solve the problems of inconvenience in daily use and fatigue caused by the large - diameter device.

[0007] Optionally, the length of the thickened glue layer perpendicular to the upper end face of the first housing is set to 1.1 - 1.6 mm.

[0008] Further, the distance between the upper end surface of the first housing and the cover plate is adaptively adjusted according to the length of the thickened glue layer perpendicular to the upper end surface of the first housing, so that the cover plate is attached to the thickened glue layer.

[0009] Further, the length of the thickened glue layer parallel to the upper end surface of the first housing is set to 0.3 - 0.5 mm.

[0010] Further, the length of the thickened glue layer parallel to the upper end surface of the first housing does not exceed the edge of the top end surface of the first housing.

[0011] Further, the minimum distance between the screen FPC and the thickened glue layer is set to 0 mm.

[0012] Further, the positional tolerance between the cover plate and the first housing is within 0 - 0.05 mm.

[0013] The present invention also provides a wearable device, including a side glue - applying structure of a wearable device as described in any one of the above.

[0020] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The present invention provides a side glue - applying structure of a wearable device. The following is combined withFigures 1 to 2 A detailed description will be given.

[0022] A side dispensing structure of a wearable device includes a first housing 1. An accommodation cavity 2 is arranged inside the first housing 1. A screen FPC 3 is arranged in the accommodation cavity 2. A second housing 4 is detachably and fixedly connected to the outside of the first housing 1. The height of the top end face of the first housing 1 is set lower than the height of the top end face of the second housing 4. The first housing 1 and the second housing 4 surround to form an adhesive coating annular groove 5. A thickened glue layer 6 is arranged in the adhesive coating annular groove 5. The length of the thickened glue layer 6 perpendicular to the end face of the first housing 1 is greater than the length of the thickened glue layer 6 parallel to the end face of the first housing 1. A cover plate 7 is arranged above the thickened glue layer 6.

[0023] The present invention changes the traditional dispensing method. By setting the thickened glue layer 6, the thickness of the glue layer is increased to ensure the waterproof effect, and then the distribution length of the glue in the horizontal direction is reduced to reduce the horizontal diameter of the entire wearable device. The entire outer housing can be adaptively processed and designed according to the reduced diameter. After the entire housing is divided into the first housing 1 and the second housing 4, the horizontal diameter of the device can be reduced without affecting the waterproof effect, so as to solve the problems of inconvenience in daily use and fatigue in use brought by large-diameter devices.

[0024] In some embodiments, the length of the thickened glue layer 6 perpendicular to the upper end face of the first housing 1 is set to 1.1 - 1.6 mm. By increasing the length of the thickened glue layer 6 perpendicular to the upper end face of the first housing 1, the total length of the sealed connection and coverage between the glue layer and the side of the housing is ensured, and preparations are made for reducing the length of the thickened glue layer 6 parallel to the upper end face of the first housing 1.

[0025] In some embodiments, the distance between the upper end face of the first housing 1 and the cover plate 7 is adaptively adjusted according to the length of the thickened glue layer 6 perpendicular to the upper end face of the first housing 1, so that the cover plate 7 is arranged in a fitting manner with the thickened glue layer 6.

[0026] In some embodiments, the length of the thickened glue layer 6 parallel to the upper end face of the first housing 1 is set to 0.3 - 0.5 mm. In the prior art, in order to ensure the sealing performance of the glue layer, the horizontal coverage length of the entire glue coating layer is set to about 1.2 during glue coating. In this application, by increasing the thickness of the thickened glue layer 6 in the longitudinal direction, there is a sealed bonding distance of 1.1 - 1.6 mm between the thickened glue layer 6 and the second housing 4, so that the horizontal length of the thickened glue layer 6 is reduced, which reduces the horizontal width of the upper end face of the first housing 1, and further reduces the horizontal diameter of the entire wearable device by 0.8 - 2 mm.

[0027] In some embodiments, the length of the thickened glue layer 6 parallel to the upper end face of the first housing 1 does not exceed the edge of the top end face of the first housing 1, so as to prevent the glue from directly contacting the screen FPC 3 or other internal electronic components.

[0028] In some embodiments, the minimum distance between the screen FPC 3 and the thickened glue layer 6 can be set to a 0 mm distance, which provides the maximum allowable value of the lateral extension length for the thickened glue layer 6. On the one hand, it ensures the sealed connection between the thickened glue layer 6 and the end face of the first housing 1. On the other hand, by reducing the distance between the thickened glue layer 6 and the screen FPC 3, the lateral diameter of the wearable device is further reduced.

[0029] In some embodiments, the positional tolerance between the cover plate 7 and the first housing 1 is within 0 - 0.05 mm. This ensures the normal installation of the cover plate 7 and keeps the cover plate 7 installed in the most correct position.
