Description

Portable equipment rack capable of rotating 360 degrees

Technical Field

The application relates to the technical field of portable equipment racks, in particular to a portable equipment rack capable of rotating by 360 degrees.

Background

Currently, there is a portable device rack capable of rotating 360 degrees in the market, which can be used for placing a portable device (such as a mobile phone) thereon and driving the mobile phone to rotate 360 degrees, so that the mobile phone can shoot 360 degrees of images. The portable equipment rack consists of a base and a rotating seat. A spring device is arranged in the base, and one end of a driving shaft of the spring device is connected with the rotating shaft center of the rotating seat. Therefore, when the rotating seat rotates relative to the base in a preset rotating direction, the spring in the spring device can be wound to store energy; when the spring releases energy, the rotating seat can be driven to rotate reversely through the driving shaft.

However, such a portable equipment rack has a disadvantage in that when a user is winding up the spring in the spring device, the rotating seat is often unintentionally excessively rotated, thereby damaging the rotation-related mechanism of the spring device.

Disclosure of Invention

One of the objects of the present application is to provide a 360-degree rotatable portable equipment rack, in which the rotation-related mechanism of the spring device is not damaged by excessive rotation of the rotary base.

In order to achieve the above-mentioned objective, the present application provides a portable device rack capable of rotating 360 degrees, which includes a base, a rotating base and a rotating shaft. The base is provided with a strip device. The bottom of the swivel base has an inner ratchet structure (internal ratchet structure) with a plurality of first teeth. As for the shaft, a first end thereof is rotatably connected to the center of the inner ratchet structure, and a second end thereof is connected to the driving shaft of the spring device. The rotating shaft is provided with at least one elastic arm, each elastic arm is provided with at least one second tooth part, and each second tooth part is suitable for matching with a tooth slot between any two adjacent first tooth parts. When the rotating seat rotates relative to the base in a preset rotating direction and the thrust of each second tooth part under the contacted first tooth part is larger than the deformation resistance of the corresponding spring arm, the corresponding spring arm is elastically deformed, so that each second tooth part is matched with the next tooth slot between the first tooth parts.

In order to make the above-mentioned objects, technical features and practical implementation gain more obvious, the following description will be given with reference to the accompanying drawings.

Detailed Description

For a better understanding of the features, contents and advantages of the present application and the effects achieved thereby, the present application will now be described in detail with reference to the accompanying drawings, which are presented in the form of examples, but the drawings used herein are for illustration and description only and are not necessarily true proportions or exact arrangements upon which the application is practiced, and should not be construed as limiting the scope of the application in its practical terms with respect to the proportions or arrangements of the accompanying drawings.

The advantages, features and technical approaches to the present application will be more readily understood by reference to the following detailed description of exemplary embodiments and the accompanying drawings, and the application may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed to provide a full and thorough understanding of the present application by those skilled in the art, and the present application will be limited only to the appended claims.

Please refer to fig. 1 to 11. The portable device holder 100 capable of rotating 360 degrees according to an embodiment of the present application includes a base 160, a rotating base 110 and a rotating shaft 150. The base 160 has a spring mechanism 180. The bottom of the rotary seat 110 has an inner ratchet structure 120, and the inner ratchet structure 120 has a plurality of first teeth 121. As for the shaft 150, a first end 150-1 thereof is rotatably coupled to the center of the inner ratchet structure 120, and a second end 150-2 thereof is coupled to the drive shaft 180-1 of the spring device 180. For example, the center of the inner ratchet structure 120 may have a through hole 128, such that the bolt 129 is fastened to the first end 150-1 of the rotating shaft 150 through the through hole 128, so that the rotating shaft 150 can rotate relative to the center of the inner ratchet structure 120. This connection is merely exemplary and is not intended to limit the present application. In addition, the second end 150-2 of the rotation shaft 150 may have an internal thread, and the driving shaft 180-1 may have an external thread so as to be coupled with the second end 150-2 of the rotation shaft 150. Of course, the second end 150-2 of the shaft 150 could be externally threaded, and the drive shaft 180-1 could be internally threaded.

The base 160 has a middle plate 170 and a push-push button 190 in addition to the spring device 180. The middle plate 170 may be fixed to the base 160, for example, by snap-fitting, or by screws. In addition, the middle plate 170 has a through hole 170-1, and the diameter of the through hole 170-1 is larger than that of the body of the rotation shaft 150.

As for the spring gear 180, it includes a spring 180-2, a gear set 180-3 and a reduction gear 180-4 in addition to the driving shaft 180-1, and the driving shaft 180-1, the spring 180-2, the gear set 180-3 and the reduction gear 180-4 are operatively connected to each other. The rotation axis (not shown) of the reduction gear 180-4 has a plurality of blades (shown as reference 180-5). When the rotary base 110 rotates relative to the base 160 in the preset rotation direction 123, the driving shaft 180-1 drives (in this case, winds) the spring 180-2 to store energy, and the spring 180-2 drives the reduction gear 180-4 to rotate through the gear set 180-3. After winding the spring 180-2, the user may press the push button 190 so that the boss 190-1 of the push button 190 may move forward into the rotational path of the blades 180-5, thereby preventing the reduction gear 180-4 from continuing to rotate, and thereby preventing the spring 180-2 from releasing energy. When the user presses the push button 190 again, the protrusion 190-1 is retracted from the rotational path of the blades 180-5 to return to the original position, so that the reduction gear 180-4 can continue to rotate, thereby allowing the spring 180-2 to release energy. At this time, the spring 180-2 drives the rotary base 110 to rotate reversely through the driving shaft 180-1 and the rotating shaft 150.

Please refer to fig. 10 to fig. 15. The rotating shaft 150 has at least one spring arm 150-3, for example, two spring arms 150-3. Each spring arm 150-3 has at least one second tooth 150-4, and each second tooth 150-4 is adapted to mate with the tooth slot 122 between any two adjacent first teeth 121. Each first tooth 121 has a contact surface 121-1 and a contact surface 121-2, and each second tooth 150-4 has a contact surface 150-5 and a contact surface 150-6. The length of contact surface 121-1 is greater than the length of contact surface 121-2 and the length of contact surface 150-5 is greater than the length of contact surface 150-6.

Taking the example shown in fig. 10 to 11 as an example, when the rotating base 110 starts to rotate relative to the base 160 according to the preset rotation direction 123, the contact surfaces 121-1 of the two first teeth 121 contact the contact surfaces 150-5 of the two second teeth 150-4, so as to drive the rotating shaft 150 to rotate accordingly. Thus, spring 180-2 begins to store energy. When the spring 180-2 has stored a certain amount of energy, and thus the pushing force of each second tooth portion 150-4 by the contacted first tooth portion 121 is greater than the deformation resistance of the corresponding spring arm 150-3, the corresponding spring arm 150-3 is elastically deformed, so that each second tooth portion 150-4 is matched with the next tooth slot 122 between the first tooth portions 121. Taking the examples shown in fig. 12 to 15, the second tooth portion 150-4 is originally matched to the tooth slot 122-1, and after the elastic arm 150-3 is elastically deformed and rebounded to the original shape, the second tooth portion 150-4 is matched to the next tooth slot 122-2.

As can be seen from the above description, when the user winds up the spring 180-2 in the spring device 180, the rotating base 110 always idles even if the user rotates the rotating base 110 excessively by accident, so that the rotation related mechanism of the spring device 180 is not damaged due to the excessive rotation of the rotating base 110.

Although the design of the inner ratchet structure 120 and the rotating shaft 150 has been described in the above description, the present application is not limited thereto. For example, if the predetermined rotation direction of the rotating base 110 is different from the predetermined rotation direction 123, the design of the first teeth 121 of the inner ratchet structure 120, the bending direction of the spring arm 150-3 of the rotating shaft 150, and the design of the spring device 180 must be modified accordingly. Several examples are listed below.

Please refer to fig. 16. As shown in fig. 16, the inner ratchet structure 220 has a plurality of first teeth 221. Each first tooth 221 has a contact surface 221-1 and a contact surface 221-2, and the lengths of the contact surfaces 221-1 and 221-2 are substantially equal. In addition, the shaft 250 has at least one spring arm 250-3, for example, two spring arms 250-3. Each spring arm 250-3 has at least one second tooth 250-4, and each second tooth 250-4 is adapted to mate with the tooth space between any two adjacent first teeth 221. Each second tooth 250-4 has a contact surface 250-41 and a contact surface 250-42, and the contact surface 250-41 has a length greater than the contact surface 250-42. In other words, the first teeth 220 have symmetrical tooth shapes, and the second teeth 250-4 have asymmetrical tooth shapes. When the corresponding rotating seat rotates relative to the corresponding base according to the preset rotating direction 123, the contact surfaces 221-1 of the two first teeth 221 are contacted with the contact surfaces 250-41 of the two second teeth 250-4. In addition, in fig. 16, reference numeral 250-2 denotes a second end of the rotation shaft 250. Since the first teeth 220 have symmetrical tooth shapes, the rotation related mechanism of the spring device can be protected no matter which rotation direction the corresponding rotating seat rotates excessively.

Please refer to fig. 17. As shown in fig. 17, the inner ratchet structure 320 has a plurality of first teeth 321. Each first tooth 321 has a contact surface 321-1 and a contact surface 321-2, and the length of the contact surface 321-1 is greater than the length of the contact surface 321-2. In addition, the shaft 350 has a spring arm 350-3, and the spring arm 350-3 is a ring spring arm. The spring arm 350-3 has at least one second tooth 350-4, for example, two second teeth 350-4. Each second tooth 350-4 is adapted to mate with a tooth slot between any two adjacent first teeth 321. Each second tooth 350-4 has a contact surface 350-41 and a contact surface 350-42, and the contact surface 350-41 has a length greater than the contact surface 350-42. In other words, the first teeth 321 and the second teeth 350-4 have asymmetric tooth shapes. When the corresponding rotating seat rotates relative to the corresponding base according to the preset rotating direction 123, the contact surfaces 321-1 of the two first teeth 321 are contacted with the contact surfaces 350-41 of the two second teeth 350-4. In addition, in fig. 17, reference numeral 350-2 denotes a second end of the rotation shaft 350.

Please refer to fig. 18. As shown in fig. 18, the inner ratchet structure 420 has a plurality of first teeth 421. Each first tooth 421 has a contact surface 421-1 and a contact surface 421-2, and the lengths of the contact surfaces 421-1 and 421-2 are substantially equal. In addition, the rotating shaft 450 has a spring arm 450-3, and the spring arm 450-3 is a ring spring arm. The spring arm 450-3 has at least one second tooth 450-4, for example, two second teeth 450-4. Each second tooth 450-4 is adapted to mate with the tooth slot between any two adjacent first teeth 421. Each second tooth 450-4 has a contact surface 450-41 and a contact surface 450-42, and the length of the contact surface 450-41 is greater than the length of the contact surface 450-42. In other words, the first teeth 421 have symmetrical tooth shapes, and the second teeth 450-4 have asymmetrical tooth shapes. When the corresponding rotating base rotates relative to the corresponding base along the preset rotation direction 123, the contact surfaces 421-1 of the two first teeth 421 contact the contact surfaces 450-41 of the two second teeth 450-4. Further, in fig. 18, reference numeral 450-2 denotes a second end of the rotation shaft 450.

Please refer to fig. 19 to fig. 20. Fig. 19 shows a state in which the cradle 110 has not yet placed any portable device, and fig. 20 shows a state in which the cradle 110 has placed a portable device (e.g., a mobile phone 900). The manner of designing the rotary base 110 will be described below.

Please refer to fig. 19-33. The rotating seat 110 includes a fixed member 113, a movable member 115, an elastic pad 112, an elastic pad 114, an elastic member 116, an elastic member 117, a limiting member 118 and a limiting member 119. The fixing member 113 has a rail 113-11, a rail 113-12, a limit groove 113-2, fixing holes 113-41 to 113-48, and at least one fixing hole 113-5. In addition, the bottom of the fixing member 113 has the protruding columns 113-61, the protruding columns 113-62, the screw holes 113-7 and the inner ratchet structure 120. The movable member 115 has fixing holes 115-11 to 115-14 and has at least one fixing hole 115-2. In addition, the bottom of the movable member 115 has a boss 115-31, a boss 115-32 and a screw hole 115-4. The posts 115-31 and 115-32 are configured to pass through the tracks 113-11 and 113-12, respectively. Further, as shown in fig. 19, the fixed member 113 and the movable member 115 together form a first U-shaped portion 100-1.

The elastic pads 112 and 114 are made of rubber or silica gel, for example. The outer wall surface of the elastic pad 112 has positioning portions 112-11 to 112-18, and these positioning portions 112-11 to 112-18 are respectively fixed to the fixing holes 113-41 to 113-48 of the fixing member 113. In addition, the elastic pad 112 also has an extension 112-3. The extension portion 112-3 has at least one positioning portion 112-31, and the positioning portions 112-31 are respectively fixed to the fixing holes 113-5 of the fixing member 113. In addition, the inner wall of the elastic pad 112 has at least one elastic fin, such as two elastic fins, as shown by the marks 112-21 and 112-22, respectively. At least one of the flexible fins has a guide ramp 112-211.

The outer wall of the elastic pad 114 has positioning portions 114-31 to 114-34, and the positioning portions 114-31 to 114-34 are respectively fixed to the fixing holes 115-11 to 115-14 of the movable member 115. In addition, the resilient pad 114 also has an extension 114-2. The extending portion 114-2 has at least one positioning portion 114-21, and the positioning portions 114-21 are respectively fixed to the positioning holes 115-2 of the movable member 115. In addition, the inner wall of the elastic pad 114 has at least one elastic fin, such as two elastic fins, as shown by the reference numerals 114-11 and 114-12, respectively. At least one of the flexible fins has a lead-in ramp 114-111. In addition, as shown in FIG. 19, the elastic pads 112 and 114 together form a second U-shaped portion 100-2, and the second U-shaped portion 100-2 can be accommodated in the first U-shaped portion 100-1. By such a design of the guide slope, the portable device can be easily placed in the second U-shaped portion 100-2.

It should be noted that the number and shape of the positioning portions of the outer wall surfaces of the elastic pads 112 and 114 can be changed according to the actual design requirements, and the number and shape of the positioning portions of the extending portions of the elastic pads 112 and 114 can be changed according to the actual design requirements. In addition, the number and shape of the elastic fins on the inner wall surfaces of the elastic pads 112 and 114 can be changed according to the actual design requirements, and the shape of the guiding inclined plane can be changed according to the actual design requirements. Of course, if the design of the elastic pads 112 and 114 is modified, the designs of the fixed member 113 and the movable member 115 should also be considered whether the corresponding modifications are necessary.

Elastic member 116 is connected between posts 113-61 and posts 115-31, and elastic member 117 is connected between posts 113-62 and posts 115-32. In this example, the elastic members 116 and 117 are implemented as springs, but the present application is not limited thereto. As shown in fig. 32, each end of the spring defines a collar (shown as 116-11 and 116-12) for securing to a corresponding post.

In this example, the stoppers 118 and 119 have the same design, and are exemplified by the stopper 119 shown in fig. 31. The stopper 119 has a groove 119-11, a groove 119-12, a through hole 119-2, and a stopper column 119-3. The recess 119-11 is configured to receive the post 115-31 of the movable member 115 and to cooperate with the post 115-31 to retain the collar of one end of the resilient member 116. The recess 119-12 is configured to receive the post 115-32 of the moveable member 115 and cooperate with the post 115-32 to retain a collar on one end of the resilient member 117. The limiting post 119-3 is configured to pass through the limiting slot 113-2 of the fixing member 113. The through hole 119-2 is used for the bolt 119-9 to pass through to be locked to the screw hole 115-4 of the movable member 115. Similarly, one of the grooves of the limiting member 118 is configured to receive the boss 113-61 of the fixing member 113, and to clamp the collar at the other end of the elastic member 116 together with the boss 113-61. The other groove of the stopper 118 is used for receiving the boss 113-62 of the fixing member 113 and clamping the collar at the other end of the elastic member 117 together with the boss 113-62. The through hole of the limiting member 118 is used for the bolt 118-9 to pass through and be locked to the screw hole 113-7 of the fixing member 113. Fig. 33 shows the rotation seat 110 in a state in which the elastic members 116 and 117 are stretched, wherein the stopper 119 is removed to clearly show the state.

It should be noted that the limiting member 118 may be provided without a limiting post. In addition, if the fixing member 113 does not have the limiting groove 113-2, the limiting member 119 may also have no limiting post 119-3. In addition, if both ends of the elastic member 116 can be firmly fixed on the corresponding two posts, and both ends of the elastic member 117 can be firmly fixed on the corresponding two posts, the rotation seat 110 can also be free from the limiting members 118 and 119. It should be noted that the portable device holder 100 that can rotate 360 degrees may be a portable device holder that does not use the push button 190. Of course, in this case, the design of the base 160 and the spring device 180 of the portable equipment rack 100 must be changed correspondingly.

Referring to fig. 34 to 35, the two drawings show different designs of the elastic pad. As shown in fig. 34, the guiding inclined surface 202-1 of the elastic pad 202 and the guiding inclined surface 204-1 of the elastic pad 204 of the portable device holder 200 capable of 360-degree rotation are both wavy. Of course, the guiding inclined planes may all have a saw-tooth shape, or at least one of a wavy shape and a saw-tooth shape, or only one of the elastic pads 202 and 204 may have at least one of a wavy shape and a saw-tooth shape. As shown in fig. 35, the elastic pads 302 and 304 of the portable device holder 300, which can rotate 360 degrees, have no extension. Of course, only one of the elastic pads may have no extension.

It should be noted that the design of the elastic pad 302 of the portable device holder 300 capable of rotating 360 degrees may be changed to the design of the elastic pad 304, that is, the elastic pad 302 is changed from L-type to I-type. Thus, the elastic pad 304 and the modified elastic pad 302 can be disposed on two side walls of the first U-shaped portion of the portable device rack 300. Of course, the fixing member of the swivel base of the portable device holder 300 that can rotate 360 degrees must also be modified correspondingly. Similarly, the design of the elastic pad 202 of the portable device holder 200 capable of rotating 360 degrees may be changed to the design of the elastic pad 204, and the design of the elastic pad 112 of the portable device holder 100 capable of rotating 360 degrees may be changed to the design of the elastic pad 114. Of course, the two resilient pads employed by each portable device holder may be such that at least one of them does not have an extension.

Please refer to fig. 36. The 360 degree rotatable portable device holder 400 shown in this figure differs from each of the portable device holders described above in that the bottom of the base has a nut 402 for locking to a foot rest or a support frame.

Please refer to fig. 37 to 39. The drawings show another design mode of the fixed part, another design mode of the movable part and another design mode of the elastic part respectively. As shown in fig. 37, the design of the fixing member 502 is substantially the same as that of the fixing member 113, and the fixing member 502 has the rails 502-21, the rails 502-22, the limit grooves 502-3, the posts 502-11 and the posts 502-12, but the difference is that the posts 502-11 and 502-12 of the fixing member 502 have the through holes 502-111 and 502-121, respectively, and the bottom of the fixing member 502 does not need to have screw holes for fixing the limit member.
