As shown in fig. 1A, the rotating bracket 1 includes a first mounting portion 11, a second mounting portion 12, and a connecting assembly 13 assembled together.
In the present embodiment, the first mounting portion 11 is used for fixed mounting with the first member. As shown in fig. 1A, the first mounting portion 11 includes a first base 111 and a first lug 112 formed in one piece. The first base 111 is bent in accordance with the shape of the first member, and the first base 111 is formed with a plurality of holes corresponding to the first member, and the first base 111 can be fixedly attached to the first member by means of connectors inserted into the holes. The first lug 112 extends from an edge portion of the first base 111, and the first lug 112 is formed with a first mounting hole 11h therethrough, the first mounting hole 11h being for insertion therethrough of the threaded connector 131 of the connection member 13. In the present embodiment, the inner contour (cross-sectional contour) of first mounting hole 11h matches the outer contour (cross-sectional contour) of screw 1311 of threaded connector 131 so that first mounting portion 11 is fixed relative to connection assembly 13.
In the present embodiment, the second mounting portion 12 is used for fixed mounting with the second member. As shown in fig. 1A, the second mounting portion 12 includes a second base 121 and a second lug 122 formed in one piece. The second base 121 is formed in a flat plate shape, and the second base 121 is formed with a plurality of holes corresponding to the second member, and the second base 121 can be fixedly attached to the second member by connectors inserted into the holes. A second lug 122 extends from an edge portion of the second base 121, and the second lug 122 is formed with a second mounting hole 12h therethrough, the second mounting hole 12h being for insertion therethrough of the threaded connector 131 of the connection member 13. In the present embodiment, the inner contour of the second mounting hole 12h does not completely match the outer contour of the screw 1311 of the threaded connector 131, and the second mounting hole 12h is formed as a circular hole so that the second mounting portion 12 can rotate relative to the connecting assembly 13.
In the present embodiment, the connection assembly 13 is assembled with the first and second mounting parts 11 and 12 such that the first and second mounting parts 11 and 12 are connected to each other. The first mounting portion 11 is fixed relative to the attachment assembly 13 and the second mounting portion 12 is rotatable about the threaded connection 131 of the attachment assembly 13. Further, the first mounting portion 11 and the second mounting portion 12 can maintain a predetermined relative posture when the first mounting portion 11 is turned to the relative posture with respect to the second mounting portion 12 by rotating the cradle 1. As shown in fig. 1A, the connecting assembly 13 includes a threaded connecting member 131, a nut 132, two pressing washers (a first pressing washer 133a and a second pressing washer 133b), two rotation stop washers (a first rotation stop washer 134a and a second rotation stop washer 134b), and an angle control washer 135 assembled together. In the axial direction of the threaded connector 131, the threaded connector 131 is inserted into the first lug 112, the angle control washer 135, the second lug 122, the first rotation stop washer 134a, the first pressing washer 133a, the second pressing washer 133b, the second rotation stop washer 134b, and the nut 132 in this order, and the rotational connection between the first mounting part 11 and the second mounting part 12 is achieved by the threaded engagement of the threaded connector 131 and the nut 132.
As shown in fig. 1A, the threaded connection 131 includes a screw head 1312 and a screw 1311 formed as one body. The screw head 1312 is fixed to one end of the screw 1311, and the other end of the screw 1311 is threadedly engaged with the nut 132. The outer diameter of the screw head 1312 is larger than that of the screw 1311. The outer peripheral portion of the screw 1311 is formed with not only a male screw threadedly engaged with the nut 132 but also up to two rotation stop planes on the outer peripheral portion of the screw 1311. The two rotation stop planes divide the external thread into two parts, so that the outer profile of the cross section of the screw 1311 is substantially oblong. The nut 132 is formed with an internal thread that mates with the external thread of the screw 1311. In this way, in a state where the screw 1311 is inserted into the respective components in this order, the respective components fitted to the screw 1311 are connected together by the screw 1312 and the nut 132.

The first and second rotation stop washers 134a and 134b are each formed with a first through hole 134h such that they are fitted over the threaded connection member 131. Since the inner contour of first through-hole 134h matches the outer contour of threaded rod 1311, first rotation stop washer 134a and second rotation stop washer 134b are fixed with respect to threaded connection 131.
As shown in FIG. 1A, angle control shim 135 may be a flat shim. The angle control washer 135 is formed with a second through hole 135h such that it is fitted over the threaded connection member 131. Since the inner contour of second through-hole 135h matches the outer contour of threaded rod 1311, angle control washer 135 is fixed relative to threaded connection 131. In addition, the outer peripheral portion of the angle control shim 135 is also formed with a first stepped portion and a second stepped portion that are arranged at intervals in the circumferential direction of the angle control shim 135. In the process that the second mounting portion 12 rotates relative to the connecting assembly 13, the second base 121 is matched with the first stepped portion and the second stepped portion, so that the rotation angle range of the second mounting portion 12 relative to the first mounting portion 11 can be controlled. In an alternative, other structures matched with the first step portion and the second step portion may be formed on the second mounting portion 12 to achieve the above functions.
In this way, the angle control washer 135 and the first rotation stop washer 134a are provided on both sides of the second lug 122 that is rotatable with respect to the threaded connector 131, and the first rotation stop washer 134a and the second rotation stop washer 134b are provided on both sides of the two pressing washers 133a, 133b that are rotatable with respect to the threaded connector 131. Thereby, it is possible to provide frictional damping to the second lug 122 and the two pressing pads 133a, 133b, facilitating the holding of the second mounting portion 12 in a predetermined attitude with respect to the first mounting portion 11.
The following describes the structure of an electronic apparatus including a rotating stand according to a first embodiment of the present application.
As shown in fig. 1B, the electronic device according to the present application includes a base 2 and a head 3 in addition to the rotating bracket 1, wherein a first mounting portion 11 of the rotating bracket 1 is fixedly mounted on the base 2, and a second mounting portion 12 of the rotating bracket 1 is fixedly mounted on the head 3. The base 2 is used to support the whole electronic device and can be stably placed on a horizontal placement surface. The head 3 may include a display screen and the like as required functional devices and a face recognition module and the like as required functional modules. Thus, by rotating the stand 1, the head 3 can be rotated within a predetermined range with respect to the base 2.
In the present embodiment, as shown in fig. 1B, the base 2 of the electronic apparatus is placed on a horizontal surface. In the side view shown in fig. 1B, the electronic apparatus is in an initial state, and the surface of the display screen of the head 3 is as shown along the vertical direction V, that is, at 90 ° to the reference line R parallel to the horizontal direction H; as the head 3 is turned relative to the base 2 via the rotating bracket 1, the display screen of the head 3 is gradually raised, and finally the obtuse angle formed by the surface of the display screen of the head 3 and the reference line R in the side view is 120 °. In this way, the head 3 of the electronic device can be adjusted by up to 30 ° as required, so that the operability of the electronic device is improved.
It can be understood that the rotating bracket according to the present application can be applied not only to an automatic payment terminal or an access control terminal using face recognition, but also to other electronic terminals that all have a requirement that a functional module rotates within a certain range with respect to a support structure. For example, when the method is applied to an automatic payment terminal using face recognition, a binocular living body detection face recognition module in a functional module of the terminal needs to be aligned with the face of a user for recognition before information in the payment module can be extracted to complete payment. Under the condition that the functional module is not aligned to the face of the user in the initial state, the rotating support can be utilized to enable the functional module (the head 3) to rotate relative to the supporting structure (the base 2), so that the functional module can be guaranteed to be aligned to the face of the user with different heights and different postures to smoothly scan the face, and the experience of the user in using the electronic terminal is greatly improved. Further, in the present embodiment, the maximum rotation range of the head 3 of the electronic terminal with respect to the reference line R is limited to 30 °, which is the most appropriate range that can be selected in most cases in all cases of the user when the use of the automatic payment terminal using the face recognition is sufficiently considered.
