The various embodiments may be combined with each other to form other embodiments not shown in the following description.

The embodiment provides a double-lens exhibition stand structure, and aims to solve the problem that the existing exhibition stand is poor in exhibition effect. Specifically, referring to fig. 1 and 2, the stand structure includes a mount 10 and a lens group.

The mounting frame 10 is a carrier of the lens group, that is, the lens group is mounted on a corresponding mounting position via the mounting frame 10, the mounting position can be a specific device or a wallboard, and is not limited herein, and only the lens group is required to collect required information of a displayed object according to an operation requirement.

The lens group includes a first lens 20 and a second lens 30, wherein the first lens 20 and the second lens 30 are both mounted on the mounting frame 10. The first lens 20 is used for collecting panoramic information of the displayed object, and the second lens 30 is used for collecting magnification information of the displayed object.

When the panoramic information of the displayed object needs to be collected, the first lens 20 can be opened and the second lens 30 can be closed, and at the moment, the first lens 20 collects the corresponding panoramic information and uploads the panoramic information; or the first lens 20 and the second lens 30 may both be opened, the first lens 20 and the second lens 30 synchronously acquire and upload corresponding panoramic information, and the receiving end performs panoramic information and selects the panoramic information of the first lens 20; the first lens 20 and the second lens 30 may be both opened, the first lens 20 and the second lens 30 may synchronously capture corresponding images, and then upload panoramic information captured by the first lens 20. When the magnification information of the displayed object needs to be collected, the operations of the first lens 20 and the second lens 30 are opposite, which may specifically refer to the above description and will not be described herein again.

It should be noted that the mounting frame 10 is further provided with a corresponding circuit board, which is connected with the processors of the first lens 20 and the second lens 30 and uploads the collected information to a display device or a server.

The specific implementation process of the exhibition stand structure can be as follows; the mounting frame 10 is fixed on a corresponding mounting position, then the displayed object is placed according to the operation requirement, when the panoramic information of the displayed object needs to be collected, the first lens 20 plays a leading role, and when the amplification information of the displayed object needs to be collected, the second lens 30 plays a leading role. Therefore, the exhibition stand has good panoramic effect, is suitable for amplifying the displayed object, and optimizes the exhibition effect.

As an alternative solution, the mounting frame 10 includes a base 101 and a cantilever 102. The first lens 20 and the second lens 30 are both fixedly mounted on a cantilever 102, and the cantilever 102 is fixedly or movably mounted on the base 101. The surface of the mounting block 10 connected to the suspension arm 102 is referred to as a first mounting surface 1012, and the surface opposite to the first mounting surface 1012 is referred to as a second mounting surface, which can be used for fixing to a mounting position.

When collecting information of the displayed object, the cantilever 102 should be horizontally disposed, and the bottom surface of the cantilever 102 is denoted as a surface a 1021. The first lens 20 and the second lens 30 are both directed downward and mounted on the face a 1021. When the first mounting surface 1012 and the second mounting surface are both horizontally disposed, then the mounting location should have extensions in the vertical and horizontal directions to meet the mounting requirements of the second mounting surface; when the first mounting surface 1012 and the second mounting surface are both vertically disposed, then there should be an extension in the vertical direction of the mounting location to meet the mounting requirements of the second mounting surface. In order to reduce the restriction on the installation position, the first installation surface 1012 and the second installation surface are preferably vertically arranged.

Further, the first lens 20 employs a digital zoom lens; the second lens 30 employs an optical zoom lens. The digital zoom lens enlarges the area of each pixel in the picture through a built-in processor, thereby achieving the purpose of amplification and having good panoramic effect; the optical zoom lens realizes zooming by means of the internal structure thereof, so that the magnification effect is good. It is worth noting that when the optical zoom lens is used, the displayed object needs to be moved to realize the amplification of a specific point.

The first lens 20 and the second lens 30 are preferably oriented the same, i.e., when open, both are facing vertically downward, thus facilitating user determination of the corresponding focal point and adjustment of the position. The distance between the first lens 20 and the second lens 30 may be 10cm to 30cm, so as to reduce the difference between the first lens 20 and the second lens 30 when the first lens 20 and the second lens 30 synchronously/asynchronously collect information.

A line connecting the first lens 20 and the second lens 30 is denoted as a line l, and a perpendicular bisector of the line a is denoted as a line y. In order to avoid the influence of strong light on the collection effect, a light supplement lamp 40 may be further disposed on the cantilever 102. The light supplement lamps 40 are preferably two or more and are uniformly divided into two groups, the light supplement lamps 40 of each group are distributed along the l direction, the two groups of light supplement lamps 40 are distributed along the y direction, and the first lens 20 and the second lens 30 are located between the two groups of light supplement lamps 40.

As an optional technical solution, the first mounting surface 1012 of the base 101 is provided with a receiving groove 1011, and the shape of the receiving groove 1011 matches with the shape of the cantilever 102; one end of the cantilever 102 away from the first lens 20 is rotatably connected to the base 101 via a rotating shaft. An included angle between the cantilever 102 and the first mounting surface 1012 is denoted as an angle a, and when the angle a is 0 degree, the cantilever 102 is completely accommodated in the accommodating groove 1011, so that when the exhibition stand is not used, the cantilever 102 is accommodated, and the occupied space is reduced; when angle a is 90 degrees, cantilever 102 is perpendicular to first mounting surface 1012, which is the optimal pick angle.

It can be understood that when the suspension arm 102 is received in the receiving cavity 1011, the surface a1021 is preferably oriented towards the inner wall of the receiving cavity 1011, so as to reduce the contact between the first lens 20 and the second lens 30 and the external environment when the exhibition stand is not in use.

Further, when the axis of the rotating shaft is parallel to the horizontal direction, the receiving groove 1011 is vertically arranged; when the axis of the rotation shaft is parallel to the vertical direction, the receiving groove 1011 is disposed horizontally. However, when the receiving groove 1011 is horizontally disposed, the cantilever 102 may have low stability under the action of its own weight, and therefore, the axis of the rotating shaft is preferably parallel to the vertical direction, so as to prevent the cantilever 102 from being influenced by its own weight and stable.

As an optional technical solution, the exhibition stand structure further includes a switching member. It should be noted that the first lens 20 has an activation end and a zoom end, the second lens 30 also has an activation end and a zoom end, the first lens 20/the second lens 30 can be activated through the activation end, and the first lens 20/the second lens 30 can enter a corresponding zoom mode through the zoom end, where the zoom mode corresponds to a corresponding magnification.

The switching member is connected to the starting end of the first lens 20 and the starting end of the second lens 30, that is, the switching member can cause the first lens 20 and the second lens 30 to start asynchronously. The switching member may employ a knob 50 or a remote controller, and when the knob 50 is employed, switching of the first lens 20 and the second lens 30 is achieved by rotating the knob 50.

The switching member is also connected to the zoom end of the second lens 30. Specific operations can be referred to the following examples: when the exhibition stand is used, the exhibition stand defaults to use the first lens 20, when the second lens 30 needs to be used for magnifying the displayed object, the knob 50 is turned rightwards, namely the first lens 20 is closed and the second lens 30 is opened, the knob 50 is continued to be turned rightwards, and the displayed object can be further magnified until the displayed object is magnified to the maximum.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
