[0017] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0020] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0021] This embodiment provides a power interface structure for an electronic visual aid. Figure 1 , including a main body 1, which is in the form of a square handheld device and can be held by a user. A display screen is provided on one side of the main body 1, and a camera and other components for image acquisition are provided on the other side of the opposite side. A charging structure is provided at one of the side frames of the main body 1 for use with an external power cord to provide power to maintain the visual aid.

[0022] Reference Figure 2 and Figure 3 The charging structure includes a power hole opened on the body 1, the power hole is a circular structure and is connected to the inside of the body 1. A circuit board is arranged inside the body 1, and a power interface 12 is arranged on the circuit board for matching with the connector of the power line. The body 1 includes a front and rear shell 11, and the two shells 11 are fixed by snapping together to form a space for accommodating the circuit board in the body 1, wherein the front and rear shells 11 are respectively provided with semicircular notches, so that when the two shells 11 are matched to form the body 1, the two notches are matched to form the power hole, and the power hole is opposite to the power interface 12.

[0023] When the power cord connector is inserted, the power cord connector passes through the power hole and cooperates with the power interface 12 to realize power supply and charging of the visual aid.

[0024] The visual aid is mainly used in the daily life of the visually impaired. With the help of the image acquisition and magnified display functions of the product, the visual ability of the visually impaired is enhanced. However, the charging components of electronic products are generally universal standard parts, such as power cords, power plugs, connectors, etc. There are various models of existing power plugs and connectors. Circular connectors or USB connectors are more commonly used. The sizes of these connectors are generally small, which makes it difficult for the visually impaired to identify them visually. In addition, they are connected by plugging, which requires visual assistance for alignment during the connection operation, which further increases the difficulty of use for the visually impaired, making it difficult for them to find the charging position and connect correctly during use. The circular connector used in this embodiment also has the problem of being difficult to identify and align.

[0025] In order to solve the above problem, this embodiment provides a ring sleeve 2 in the power hole. Figure 3 and Figure 4The ring sleeve 2 is in a circular ring structure and is coaxially matched with the power hole. The ring sleeve 2 is axially penetrated so that the power cord connector can pass through and enter the body 1 to cooperate with the power interface 12.

[0026] The inner diameter of the ring sleeve 2 is slightly larger than the outer diameter of the power cord connector. When the power cord connector is inserted, the inner wall of the ring sleeve 2 and the outer wall of the power cord connector are clearance-matched, which on the one hand provides guidance and limitation during insertion, and on the other hand prevents the power cord connector from loosening after insertion.

[0027] The inner top of the ring sleeve 2 is provided with a chamfered surface 21 along the circumferential direction, and the chamfered surface 21 is connected with the inner wall of the ring sleeve 2 to form a flaring effect, thereby increasing the area that the power cord connector can be aligned with, so that the visually impaired can more easily align the connector with the ring sleeve 2, and when the power cord connector is against the chamfered surface 21, the connector can also be quickly guided to slide inward into the through hole to guide the user to achieve connection.

[0028] Furthermore, when the ring sleeve 2 is installed, it protrudes from the surface of the body 1 so that the user can determine the position of the ring sleeve 2 by hand, which is convenient for alignment.

[0029] Furthermore, the surface of the ring sleeve 2 is also provided with a coating, and the coating adopts a reflective coating or a high-gloss coating, the color and gloss of which are different from the surface of the main body 1, and are more conducive to reflection than the main body 1, and thus clearly stand out from the main body 1, so that visually impaired people with low vision can more easily see the position of the ring sleeve 2.

[0030] The outer periphery of the ring sleeve 2 is provided with a block 22 for achieving installation and fixation with the main body 1. The block 22 is extended outwardly along the radial direction of the ring sleeve 2, and there are two blocks 22, which are respectively located on opposite sides of the outer peripheral wall of the ring sleeve 2. The main body 1 is provided with a slot 13 for cooperating with the block 22. There are two slots 13, which are respectively arranged on the inner walls of the notches on the two outer shells 11. During installation, one of the blocks 22 is extended into the corresponding slot 13, and the two outer shells 11 are matched, so as to achieve installation of the ring sleeve 2 and the main body 1.

[0031] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
