[ detailed description ] embodiments

A foot rest module and an electronic device having the same according to embodiments of the present invention will be described with reference to the accompanying drawings, wherein like elements are denoted by like reference numerals. The sizes (length, width, or height) and ratios of the elements shown in the following drawings are merely illustrative of the interrelationships between the elements, and are not related to the sizes and ratios of the actual elements.

Fig. 1A is a perspective view of a foot rest module according to an embodiment of the invention, fig. 1B is an exploded view of the foot rest module shown in fig. 1A, fig. 1C is a cross-sectional view of the foot rest module shown in fig. 1A, and fig. 1D is a partially enlarged view of the support 11 shown in fig. 1B.

Referring to fig. 1A to 1C, the stand module 1 is used for supporting an electronic device, and includes a supporting member 11, a position control assembly 12, and a restoring elastic member 13. In addition, the foot stand module 1 of the present embodiment further includes an elastic member fixing seat 14, a rotating shaft 15, a first fixing member 16a and a second fixing member 16 b.

For clarity of describing the structure of the supporting member 11, please refer to fig. 1D, in which the supporting member 11 can be pivotally connected to the electronic device and has a first rail 111, a second rail 112, a first position P1 and a second position P2. In addition, the supporting member 11 of the present embodiment further has a third position P3 and a fourth position P4 in addition to the first position P1 and the second position P2. The first rail 111 is connected to the second rail 112 with a step therebetween (as indicated by the oval-shaped area a in fig. 1D). Herein, the third position P3 is located in the first rail 111, and the fourth position P4 is located in the second rail 112. The first guide rail 111 is defined as a track from the first position P1 to the second position P1 through the third position P3, and the second guide rail 112 is defined as a track from the second position P2 to the first position P1 through the fourth position P4, so that two ends of the first guide rail 111 and the second guide rail 112 are respectively connected to the first position P1 and the second position P2, and the pin 121 can only move between the first position P1, the third position P3, the second position P2, the fourth position P4 and the first position P1 in sequence and cannot move reversely by using the step difference between the two positions.

In other words, as shown in fig. 1B and 1D, the surface of the supporting member 11 facing the position control assembly 12 has two mutually connected guide rails with a height difference: the first guide rail 111 and the second guide rail 112 define two positioning points: the first position P1 and the second position P2 are respectively connected to two ends of the first rail 111 at the first position P1 and the second position P2, and two ends of the second rail 112 are also respectively connected to the first position P1 and the second position P2, so that the first rail 111 and the second rail 112 form an endless track. In the present embodiment, in addition to the step difference between the first rail 111 and the second rail 112, the step difference is also provided between the first position P1 and the third position P3, the step difference is also provided between the third position P3 and the second position P2, the step difference is also provided between the second position P2 and the fourth position P4, and the step difference is also provided between the fourth position P4 and the first position P1. In different embodiments, only the first guide rail 111 and the second guide rail 112 may have a step therebetween, and the first guide rail 111 and/or the second guide rail 112 may be a smooth track, which is not limited in the present invention. In addition, the side of the supporting member 11 away from the first rail 111 and the second rail 112 in the embodiment further has a supporting portion 113 (fig. 1B), so that the foot rest module 1 can be supported on a plane (e.g. a table top) by the supporting portion 113.

Referring to fig. 1B and fig. 1C, the position control assembly 12 is disposed on the supporting member 11. Here, the position control assembly 12 is disposed on a side of the supporting member 11 opposite to the return elastic member 13, and has a latch 121 slidably disposed on the first rail 111 and the second rail 112, and the latch 121 can stop at a first position P1 or a second position P2 (described in detail below) during the movement of the first rail 111 and the second rail 112.

In addition, the position control assembly 12 of the present embodiment further includes a pin setting member 122, a pin fixing seat 123 and a cover plate 124. The cover plate 124 is connected to the latch fixing seat 123, and the latch setting member 122 is located between the cover plate 124 and the latch fixing seat 123. Here, the latch setting member 122 is slidably disposed in a recess U of the latch fixing base 123. Furthermore, a corresponding through-hole 1231 is formed in the recess U, so that the pin 121 can pass through the pin setting member 122 and protrude out of the pin fixing seat 123 (fig. 1C) through the through-hole 1231, and the pin setting member 122 can be slidably disposed in the through-hole 1231 to abut against the first guide rail 111 or the second guide rail 112, thereby limiting the moving range of the pin 121 and the pin setting member 122. In other words, when the supporting member 11 rotates relative to the electronic device, the supporting member 11 can rotate relative to the rotating shaft 15, and the pin 121 is limited by the limiting groove 1231 and can only move in the first guiding rail 111 or the second guiding rail 112.

As shown in fig. 1C, the plug 121 of the present embodiment can be divided into three sections: namely a first section S1, a second section S2 and a third section S3. The second section S2 is a spring, two sides of which are respectively connected to the first section S1 and the third section S3, and the third section S3 can protrude out of the pin setting member 122 and pass through the limiting groove 1231 of the pin fixing seat 123 to prop against the supporting member 11. By using the elastic force of the spring (the second section S2), the pin 121 can be pushed against the bottom of the first and

second rails

111, 112 even if there is a step difference during the movement of the first and

second rails

111, 112, so as to prevent the pin from separating from the circular track formed by the first and

second rails

111, 112 due to the height difference.

In addition, the position control assembly 12 of the present embodiment may further have a plurality of rolling members 125, such as but not limited to balls, disposed between the latch setting member 122 and the cover plate 124, and between the latch setting member 122 and the latch fixing base 123. The rolling members 125 can reduce the resistance of the latch setting member 122 when the recess U slides, so that the movement is smoother.

The elastic restoring element 13 is disposed on the supporting element 11, and the elastic element fixing seat 14 is disposed on a side of the supporting element 11 facing away from the position control assembly 12. Here, the elastic element fixing seat 14 is connected with the supporting element 11 to form an elastic element setting portion 141, and the elastic element 13 is disposed on the elastic element setting portion 141. The elastic member 13 of the present embodiment is a torsion spring, and the shape of the elastic member setting portion 141 corresponds to the shape of the elastic member 13, so that the elastic member 13 can be limited by the elastic member setting portion 141. Here, one end of the elastic restoring element 13 can hook the elastic element fixing seat 14, and the other end thereof abuts against the side wall 114 (refer to fig. 2A) of the corresponding recess of the supporting element 11. Therefore, when the rail member 11 rotates relative to the elastic member fixing seat 14, the side wall 114 of the corresponding recess of the rail member 11 can simultaneously apply a force to the other end of the return elastic member 13 (torsion spring) to elastically deform the return elastic member 13 to generate an elastic restoring force, thereby providing a force for automatically returning the support member 11.

The rotation shaft 15 penetrates through the position control assembly 12, the supporting member 11, the elastic return member 13 and the elastic member fixing seat 14, and the supporting member 11 can rotate relative to the rotation shaft 15 (the rest members cannot rotate relative to the rotation shaft 15). Herein, the position control assembly 12, the supporting member 11, the elastic return element 13, and the elastic element fixing base 14 are sequentially disposed between the first fixing member 16a and the second fixing member 16b, and the rotating shaft 15 sequentially passes through the first fixing member 16a, the position control assembly 12, the supporting member 11, the elastic return element 13, the elastic element fixing base 14, and the second fixing member 16b, and the plurality of assemblies are connected together by, for example, a locking manner. It should be noted that, in the embodiments of the present invention, the connection manner of two or more elements or components may be locking, embedding, snapping, or clipping connection, or a combination thereof, and is not limited. For example, as shown in fig. 1B, the rotating shaft 15 sequentially penetrates through the first fixing element 16a, the position control assembly 12, the supporting element 11, the elastic return element 13, the elastic element fixing seat 14 and the second fixing element 16B, and two ends of the rotating shaft are respectively fastened together by a screw 171 and a gasket 172.

Hereinafter, referring to fig. 1D in conjunction with fig. 2A to 2D and fig. 3, how the foot rest module 1 of the present embodiment automatically changes rails, locks and releases will be described. Fig. 2A to 2D are schematic diagrams of the foot rest module shown in fig. 1B showing the support member, the elastic return member and the latch at different positions, respectively, and fig. 3 is a schematic diagram of the foot rest module shown in fig. 1A.

In some embodiments, the second fixing element 16b can be connected to the electronic device, for example but not limited to, in a locking manner, such that when the supporting element 11 rotates relative to the electronic device, the supporting element 11 can rotate relative to the rotating shaft 15 (and the electronic device) (the rest of the components cannot rotate relative to the electronic device), the pin 121 can move along the first rail 111 or the second rail 121 and elastically deform the elastic return element 13, and the elastic restoring force of the elastic return element 13 can automatically move the pin 121 on the first rail 111 or the second rail 112 and stop at the first position P1 or the second position P2. Herein, the first position P1 may be referred to as a position where the supporting portion 113 of the support 11 is opened; the second position P2 may be referred to as a position where the support portion 113 of the support 11 is closed; the third position P3 and the fourth position P4 can be referred to as the transitional position of the supporting portion 113 (i.e., the position where the short stay will automatically move to the next position), respectively.

As shown in the figure, when the latch 121 is at the first position P1 (fig. 2A), when a user applies a force to the supporting member 11 to rotate the supporting member 11 relative to the rotating shaft 15 (and the elastic member fixing seat 14), when the latch 121 moves from the first position P1 (fig. 2A) to the third position P3 (fig. 2B) along the first rail 111 (i.e. stroke 1 of fig. 3), since one end of the resilient element 13 hooks the resilient element holder 14, the other end of the elastic member abuts against the side wall 114 of the corresponding recess of the supporting member 11, so that the restoring elastic member 13 generates an elastic restoring force, and the elastic restoring force will automatically move the latch 121 from the third position P3 (fig. 2B) to the second position P2 (fig. 2C, i.e. stroke 2 of fig. 3), and stops at the second position P2 (at this time, if the force is not applied to the support 11, the latch 121 cannot move), and the support portion 113 of the support 11 is in a closed position (i.e., automatically locked).

Then, when the user applies a force to the supporting member 11 to rotate the supporting member 11 with respect to the rotating shaft 15 (and the elastic member fixing seat 14) again, and further the pin 121 moves from the second position P2 (fig. 2C) to the fourth position P4 (fig. 2D) along the second guiding rail 112 (i.e. stroke 3 of fig. 3), at this time, the rotation of the supporting member 11 also causes the elastic return member 13 to generate another elastic restoring force, and the another elastic restoring force causes the pin 121 to automatically move from the fourth position P4 (fig. 2D) to the first position P1 (fig. 2A, stroke 4 of fig. 3) and stop at the first position P1 (the pin 121 cannot move without applying a force to the supporting member 11), and at this time, the supporting portion 113 of the supporting member 11 is at the open position (i.e. automatically released). Therefore, when the supporting member 11 rotates relative to the rotating shaft 15, under the interaction of the position control assembly 12, the supporting member 11 and the return elastic member 13, the automatic rail changing, self-locking and automatic releasing functions of the latch 121 on the supporting member 11 can be realized, so that the supporting frame 113 of the supporting member 11 can be switched between different positions.

In the foot stool module 1 of the present embodiment, the first rail 111 and the second rail 112 of the supporting member 11 are connected with each other and have a step difference therebetween, and two ends of the first rail 111 and the second rail 112 are respectively connected to the first position P1 and the second position P2, and the pin 121 of the position control assembly 12 is slidably disposed on the first rail 111 and the second rail 112 and can stop at the first position P1 or the second position P2, and the elastic restoring force of the restoring elastic member 13 enables the pin 121 to automatically move on the first rail 111 or the second rail 112 and stop at the first position P1 or the second position P2, so that the foot stool module 1 of the present embodiment can realize functions of automatic rail changing, automatic locking, automatic releasing, and the like, thereby realizing the switching of the supporting portion 113 of the supporting member 11 at different positions.

The foot rest module 22 may include a support member, a position control assembly and a reset elastic member, the support member may be framed on the machine body 21 and has a first guide rail, a second guide rail, a first position and a second position, the first guide rail is connected with the second guide rail with a section difference therebetween, two ends of the first guide rail and the second guide rail are respectively connected with the first position and the second position, the position control assembly is disposed on the support member and has a bolt slidably disposed on the first guide rail and the second guide rail, the bolt may stop at the first position or the second position, and the reset elastic member is disposed on the support member; when the supporting member of the foot rest module 22 rotates relative to the electronic device 2, the pin can move along the first guide rail or the second guide rail and elastically deform the elastic return member, and the elastic restoring force of the elastic return member can cause the pin to automatically move on the first guide rail or the second guide rail and stop at the first position or the second position. The foot rest module 22 may be the foot rest module 1 or a variation thereof, and the specific technical content is described in detail above and will not be further described herein.
