[0025] 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.

[0026] 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.

[0027] 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.

[0028] This embodiment discloses a movable handle type electronic visual aid, referring to Figure 1 , 2 , 3, comprising a main body 1 and a handle arranged on the main body 1, a display screen 12 is arranged on the front of the main body 1, and an image acquisition unit is arranged on the back, including a camera 11, an LED light, etc., by pointing the camera 11 on the back of the main body 1 directly at the target object, image information can be collected and displayed on the front display screen 12, thereby achieving a vision-aiding effect, mainly serving the visually impaired, and the handle is arranged on the back of the main body 1, and the handle is movably connected to the main body 1 for multi-functional use by the user.

[0029] The handle includes a swivel seat 21 and a handle 22, wherein the swivel seat 21 is connected to the back of the body 1, wherein a rotating shaft structure is adopted at the connection, and a first rotating shaft is provided, so that the swivel seat 21 can rotate relative to the body 1 with the first rotating shaft as the center; the handle 22 is connected to the swivel seat 21, and a rotating shaft structure is also adopted at the connection, and a second rotating shaft is provided, so that the handle 22 can rotate relative to the swivel seat 21 with the second rotating shaft as the center.

[0030] The rotating shaft structures at both locations adopt damping rotating shafts to provide a certain rotation resistance, so that the handle 22 and the rotating seat 21, and the rotating seat 21 and the body 1 can be maintained in any rotation position and withstand a certain degree of external force.

[0031] Through the rotating shaft structure between the rotating seat 21 and the main body 1, and the rotating shaft structure between the handle 22 and the rotating seat 21, there are multiple position relationships between the handle and the main body 1, including but not limited to a folded state, a semi-expanded state, and a fully expanded state.

[0032] The back of the body 1 is provided with a recessed portion 13 for accommodating the handle. Figure 1 The handle is completely located in the recessed portion 13, and the surface of the handle is flush with the back of the body 1, so that the electronic visual aid forms a flat handheld device, which is more beautiful and convenient to store.

[0033] The handle 22 is a rectangular parallelepiped structure, and the handle 22 has a length direction. Figure 1 In the direction A shown in the figure, in the folded state, the length direction of the handle 22 is aligned parallel to one of the long sides of the main body 1; of the two outer walls on the handle 22 located in relative positions, one outer wall is opposite to the main body 1, and in the folded state, the outer wall on this side is in contact with the inner wall of the recessed portion 13, and the other outer wall is a supporting surface for supporting on any plane.

[0034] Specifically, one end of the handle 22 in the length direction is connected to the rotating seat 21, that is, the axial direction of the rotating shaft between the handle 22 and the rotating seat 21 is parallel to the length direction. When the handle 22 is rotated from the folded state to the semi-expanded state, the handle 22 is rotated relative to the rotating seat 21, and the rotation direction is referenced to Figure 2 The B direction shown in the figure makes the support surface form a certain angle with the main body 1, and the angle is preferably 45° to 60°. By placing the support surface on any plane, the effect of tilting the main body 1 can be achieved, so that the display screen 12 on the main body 1 is tilted and stood up for display. In the actual usage scenario, in the semi-expanded state, the user can tilt the electronic viewer on the desktop for viewing.

[0035] Furthermore, the shaft structure between the handle 22 and the rotating seat 21 is arranged near the edge of the body 1 , and accordingly, the handle 22 is arranged as a rounded edge along the length direction at the side edge, so that the handle 22 and the body 1 can rotate relative to each other smoothly.

[0036] The handle 22 is provided with a protrusion 223 at the other end relative to the shaft connection position, and a certain gap is formed between the protrusion 223 and the recessed portion 13, so that a user can insert a finger to apply force to the handle 22 to change its position.

[0037] A foot pad 221 is also provided on the support surface. The foot pad 221 is made of rubber, plastic or other materials. The foot pad 221 protrudes from the support surface so that in a semi-expanded state, the foot pad 221 contacts any plane, forming a certain gap between the support surface and the plane to reduce scratches and wear. The foot pad 221 can also increase friction to ensure the stable placement of the electronic visual aid on any plane.

[0038] In the rotating shaft structure between the rotating seat 21 and the main body 1, the axial direction of the rotating shaft is perpendicular to the back side of the main body 1, so that the rotating seat 21 can be moved along the Figure 5 The electronic viewer 10 is rotated in the direction C shown in the figure relative to the body 1 to rotate to a fully expanded state. In this state, the handle 22 is completely rotated out of the recessed portion 13 to form a portion for the user to hold. The user lifts the entire electronic viewer by holding the handle 22 to be able to move the electronic viewer to any position, and align the camera 11 on the back of the electronic viewer with any position that the user wants to view, so that relevant information can be displayed on the display screen 12 facing the user for the user to view. In layman's terms, it provides the user with the function of an electronic magnifying glass.

[0039] In the fully expanded state, the handle 22 and the swivel base 21 can still rotate relative to each other, and the position between the handle 22 and the swivel base 21 can be adjusted according to the actual needs of the user; similarly, the way in which the electronic visual aid in this embodiment switches to the fully expanded state is not limited to a specific form, and can be switched directly from the folded state to the fully expanded state, or from the semi-expanded state to the fully expanded state.

[0040] Among them, the position of the handle 22 in the fully expanded state is preferably one hundred and eighty degrees from the position in the folded state or the semi-expanded state, and can also be adjusted approximately plus or minus twenty degrees from the preferred position, and is adjusted specifically according to actual needs. Accordingly, the recessed portion 13 is provided with a flared opening 131 with a certain slope on the side close to the swivel seat 21, so as to provide the swivel seat 21 with more sufficient rotation adjustment space.

[0041] In this embodiment, for the setting of the rotation direction of the swivel seat 21 and the handle 22, it is preferred to set the first rotation axis and the second rotation axis to be perpendicular to each other. Specifically, the axial direction of the first rotation axis is perpendicular to the back side of the main body 1, and the swivel seat 21 rotates laterally relative to the back side of the main body 1. The axial direction of the second rotation axis is parallel to the back side of the main body 1, and the handle 22 rotates longitudinally relative to the back side of the main body 1.

[0042] Furthermore, a positioning block 211 is also provided on the swivel seat 21, and a positioning surface is formed on the positioning block 211. The main body 1 is provided with a docking portion 132 for abutting against the positioning surface. In the folded state or the semi-expanded state, the positioning surface and the docking portion 132 are abutted against each other. The positioning block 211 is mainly used to provide accurate positioning for the swivel seat 21 in the semi-expanded state, so that the user can maintain it in a specific position to ensure the accurate position of the handle 22.

[0043] Correspondingly, the handle 22 is provided with a groove 222 for accommodating the positioning block 211, which is used to limit the position between the handle 22 and the rotating seat 21. In the fully unfolded state, the handle 22 is held by a human hand, and the positioning block 211 cooperates with the groove 222 to maintain a fixed relationship between the handle 22 and the rotating seat 21, so as to avoid the rotation between them and cause the body 1 to tilt.
