Description

Technical Field

[0001] The utility model relates to the field of electronic product accessories, in particular to a support base and an electronic equipment bracket having the support base. Background Art

[0002] At present, products such as mobile phone holders and wireless chargers are all equipped with support bases. The support base usually includes a base and a rotating body. The rotating body and the base are stacked and can rotate relative to the base around a certain axis. However, in order to save layout space, the base and the rotating body are arranged in surface contact, and the contact surface between the two is sliding friction contact. Frequent use can easily cause damage to the base and the rotating body, affecting the service life of the product. At the same time, there is a problem of large resistance in sliding friction. Although large friction resistance can play a certain limiting role on the rotating body, so that the rotating body can be limited to the position after rotation, excessive friction resistance will cause greater resistance between the rotating body and the base during rotation, thereby affecting the user experience. Utility Model Content

[0003] The first purpose of the present invention is to provide a support base to effectively solve the deficiencies of the prior art.

[0004] The second object of the present invention is to provide an electronic equipment bracket using the above-mentioned support base structure.

[0005] In order to achieve the first purpose, the utility model adopts the following technical solutions:

[0006] A support seat comprises a base and a rotating body, wherein the rotating body and the base are stacked and can rotate relative to the base around a fixed axis; a rolling support mechanism is provided between the rotating body and the base, and the two ends of the rolling support mechanism are respectively in contact with the rotating body and the base, and the rolling support mechanism rolls as the rotating body rotates relative to the base; and also includes a positioning mechanism for limiting the rotation of the rotating body around the fixed axis.

[0007] The utility model adopts the above structure, so that the rotating body can rotate relative to the base in the form of rolling support, and the rotation angle can be limited by the positioning mechanism.

[0008] As an option, the fixed shaft is arranged on the upper surface of the base, and the rotating body is sleeved in the fixed shaft. The fixed shaft is arranged on the base, which can further simplify the product structure and is also convenient for the production of the base component and the assembly of subsequent products.

[0009] Alternatively, the rolling support mechanism includes: a plurality of ball grooves evenly arranged on the upper surface of the base around the fixed axis; and a plurality of balls, each placed in a ball groove and engaging the rotating body. This rolling support mechanism has a simple structure and is also easy to assemble.

[0010] As an option, a shaft sleeve cover is fixedly provided on the fixed shaft, and the shaft sleeve cover is located on a side of the rotating body away from the base to limit the rotating body from separating from the fixed shaft along the axial direction of the fixed shaft.

[0011] Furthermore, the outer periphery of the shaft sleeve cover plate has an arc segment with a central angle greater than 0 and less than or equal to 360 degrees; the arc segment is provided with a plurality of positioning grooves; the positioning mechanism includes a positioning pin and an elastic component, the elastic component being provided on the rotating body, the positioning pin elastically abutting against the arc segment via the elastic component, and when the rotating body rotates relative to the base, the positioning pin cooperates with the positioning groove to achieve positioning. By adopting the above-mentioned structure, the positioning mechanism enables the rotating body to rotate between 0-360 degrees and to be positioned at different rotation angles according to product design requirements.

[0012] As an option, the elastic component includes a spring seat and a compression spring, wherein the positioning pin and the compression spring are installed in the spring seat. The compression spring provides elastic force for the positioning pin to ensure that the positioning pin can always elastically contact the arc section of the shaft sleeve cover.

[0013] More preferably, the central angle of the arc segment is 180 degrees, and the arc segment is provided with three positioning grooves arranged at equal angles. This structural arrangement enables the rotating body to be positioned relative to the base at rotation angles of 0 degrees, 90 degrees, and 180 degrees.

[0014] As an option, a stop bar is radially extended from the outer periphery of the shaft sleeve cover plate, and a stop block is provided on the rotating body to cooperate with the stop bar. The stop block cooperates with the spring seat to ensure that the rotating body can only rotate between 0-180 degrees.

[0015] As an option, a plurality of small teeth are provided on the arc section between two adjacent positioning grooves. When the rotating body rotates relative to the base, the positioning pin can elastically contact the plurality of small teeth, thereby increasing the feel of the rotating body when rotating and producing a collision sound.

[0016] In order to achieve the second purpose, the utility model adopts the following technical solutions:

[0017] An electronic equipment bracket comprises a support base with the structure described above, wherein a bracket body for fixing electronic products is provided on the rotating body or the base.

[0018] The support base of the utility model adopts rolling support contact between the rotating body and the base, thereby avoiding the situation where the rotating body and the base are easily damaged due to sliding friction.

[0024] like Figures 1 to 3 As shown, the support seat described in the present invention is mainly composed of a base 1, a rotating body 2, a shaft sleeve cover plate 3, a rolling support mechanism, and a positioning mechanism 5.

[0025] The base 1 is a rectangular plate with a fixed axis 11 on its upper surface along one of its short sides. Six ball grooves 12 are evenly spaced around the fixed axis, each containing a ball 4. The grooves 12 and balls 4 form a rolling support mechanism. POM balls are preferably used for their excellent wear resistance. It should be noted that the number of ball grooves is not limited to six.

[0026] The rotating body 2 is a rectangular plate of substantially the same size as the base, with a through-hole formed on one of its short sides corresponding to the fixed shaft 11. The rotating body is sleeved within the fixed shaft via the through-hole. A sleeve cover plate 3, located on the side of the rotating body 2 facing away from the base 1, restricts the rotating body from axially disengaging from the fixed shaft. The sleeve cover plate 3 is securely connected to the fixed shaft 11 via screws or other fasteners. The rotating body is stacked on the base and abuts against the POM balls, forming a rolling support, enabling rotation relative to the base about the fixed shaft.

[0027] The outer periphery of the shaft sleeve cover plate 3 comprises an arc segment with a central angle greater than 0 and less than or equal to 360 degrees. In this embodiment, the central angle is preferably 180 degrees. Positioning grooves 31 are respectively formed on the arc segment at the positions of the central angles of 0 degrees, 90 degrees, and 180 degrees. A plurality of small teeth 32 are provided on the arc segment between the two positioning grooves 31.

[0028] The positioning mechanism 5 is primarily composed of a positioning pin 51, a spring seat 52, and a compression spring 53. The spring seat 52 is positioned on the surface of the rotating body corresponding to the shaft sleeve cover 3. The positioning pin 51 and the compression spring 53 are mounted within the spring seat 52. Consequently, the positioning pin 51, under the action of the compression spring 53, elastically abuts against the arc segment of the shaft sleeve cover 5.

[0029] In addition, a stop bar 33 extends radially from the outer periphery of the sleeve cover, and the rotating body is provided with a stopper 21 that cooperates with the stop bar. Thus, the spring seat 52, the stopper 21 and the stop bar 33 constitute a limiting mechanism that restricts the rotating body to rotate only between 0-180 degrees.

[0030] The working principle of this utility model is as follows:

[0031] In the initial state, the rotating body and the base are stacked and their projections overlap. At this time, the front end of the positioning pin 51 elastically contacts the 0-degree positioning groove, and the stop bar contacts the block 21. When the rotating body needs to rotate 90 degrees, the rotating body is pulled and rotated. Under the action of external force, the positioning pin 51 moves relative to the arc segment of 0-90 degrees and elastically contacts the small teeth, which enhances the rotation feel and produces a crisp impact sound. When the front end of the positioning pin 51 elastically contacts the 90-degree positioning groove, the rotating body completes the 90-degree rotation. Similarly, when the rotating body needs to rotate 180 degrees, the rotating body is pulled and rotated according to the above operation until the front end of the positioning pin 51 elastically contacts the 180-degree positioning groove. At this time, the stop bar 33 contacts the spring seat 52.

[0032] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
