Description

Clamping device

The present disclosure relates to a clamping device, in particular a clamping device for clamping an object.

Currently, most of the mobile device holders on the market that are installed on motorcycles or cars to clamp mobile devices require users to place the mobile device in a specific way. For example, use force to open the clamp, and then place the mobile device in the clamp to fix it. However, for this type of clamp, the force required to open the structure during the installation process is relatively large, and it is often difficult for users to install it. Sometimes, they even need to use both hands to open the clamp. In addition, sometimes too much force is applied during installation, which may accidentally cause the mobile phone to fall and cause the screen to crack. In addition, its design requires the use of multiple sets of mechanism module designs to achieve the purpose of installation. The parts assembly is relatively complex, resulting in higher costs, and consumers must also spend a higher amount of money to purchase it.

In view of the above, the present disclosure provides a clamping device suitable for clamping an object in one embodiment, and the clamping device includes a clamp, a pulling structure and a pushing member. The clamp includes a base, a center rod and two clamping claws. The center rod is connected to the base. The two clamping claws are connected to the base and are located on two sides of the base. Each clamping claw has a claw portion on a side opposite to the base, and the two claw portions are suitable for clamping an object. The pulling structure is suitable for moving relative to the base, and the pulling structure includes a hollow sleeve, two pulling members and an operating member. The hollow sleeve is sleeved on the center rod and has a first end and a second end opposite to each other. One end of the two pulling members is respectively connected to the first end of the hollow sleeve, and the other end of the two pulling members is respectively hinged to the two clamping claws. The operating member is connected to the second end of the hollow sleeve. The push member is connected to one end of the center rod opposite to the base. The operating member is adapted to drive the two pulling members to pull the two clamping claws based on the force received to move toward the push member, so that the two clamping claws are elastically deformed and the two claws release the object.

In this way, the user can hold the clamping device with one hand, place the thumb on the pushing member, and then place the index finger and middle finger on the operating member for operation. Then, after applying a force, the operating member will be driven to move toward the pushing member, thereby driving the two pulling members to pull the two clamping claws, so that the two clamping claws are elastically deformed to release the object clamped therein or allow the object to be clamped therein again. When the two clamping claws are elastically deformed and opened, the user can release or insert the object (such as a mobile device). Subsequently, stop applying the force, and the two clamping claws will return to their original positions under the action of the elastic restoring force. In this way, the two clamping claws can be easily elastically deformed and opened by one-handed operation without applying excessive force. Moreover, the number of parts is small, and most of them can be made through plastic injection molding, making production and assembly more convenient and reducing costs.

The following embodiments are presented for detailed description. However, the embodiments are only used as examples and do not limit the scope of protection of this disclosure. In addition, some elements are omitted in the drawings in the embodiments to clearly show the technical features of this disclosure. The same reference numerals will be used to represent the same or similar elements in all drawings.

Please refer to Figures 1 and 2 first. Figure 1 is a three-dimensional diagram of a clamping device assembled with an object according to an embodiment of the present disclosure, and Figure 2 is an exploded diagram of a clamping device according to an embodiment of the present disclosure. As can be seen from Figure 1, the clamping device 100 is suitable for clamping an object 90, so that the user can use the clamping device 100 to place the object 90 in various usage scenarios. The object 90 can be a mobile device such as a mobile phone or a tablet, or any item that needs to be clamped for use. The assembly scene can be, for example, assembled on a motorcycle or car for navigation, or assembled on a desktop for shooting or image viewing, etc.

As shown in Figures 1 and 2, the clamping device 100 includes a clamp 10, a pulling structure 20 and a pusher 30. The clamp 10 includes a base 11, a center rod 12 and two clamping claws 13. The center rod 12 is connected to the base 11, and the two clamping claws 13 are connected to the base 11 and are located on two sides of the base 11. Each clamping claw 13 has a claw portion 131 on one side relative to the base 11, and the two claw portions 131 are suitable for clamping the object 90. As shown in Figure 2, the center rod 12 is connected to the center position of the back of the base 11, and the claw portions 131 of the two clamping claws 13 are arranged in a direction opposite to the extension direction of the center rod 12.

Furthermore, in this embodiment, the two clamping claws 13 are arranged to extend in the upper and lower directions, but are not limited thereto. The two clamping claws 13 may also be arranged to extend in the left and right directions. The length of the two clamping claws 13 may also be set as required, for example, longer in the upper and lower directions to match the length of the long side of the object 90, and shorter in the left and right directions to match the length of the short side of the object 90. By extending in the upper and lower directions, the clamping claws 13 may have a certain length, and the force applied to the clamping claws 13 when the ends of the clamping claws 13 are to be elastically deformed may be smaller, so that the clamping claws 13 may be driven to open without applying excessive force, and the object 90 may be assembled.

The pulling structure 20 is adapted to move relative to the base 11. The pulling structure 20 includes a hollow sleeve 21, two pulling members 22 and an operating member 23. The hollow sleeve 21 is sleeved on the center rod 12 and has a first end 211 and a second end 212 opposite to each other. One end of each of the two pulling members 22 is connected to the first end 211 of the hollow sleeve 21, and the other end of each of the two pulling members 22 is hinged to the two clamping claws 13. The operating member 23 is connected to the second end 212 of the hollow sleeve 21.

As shown in Figure 2, one end of the pull member 22 is connected to the first end 211 of the hollow sleeve 21, and the other end is hinged to the clamping claw 13. The two pull members 22 are extended in the same direction as the two clamping claws 13. Therefore, if the clamping claws 13 extend in different directions, the pull member 22 can also change the direction of the extension setting accordingly, so as to be hinged to the clamping claws 13 and drive the clamping claws 13 to move.

The pusher 30 is connected to one end of the center rod 12 opposite to the base 11. The pusher 30 can be a disc-shaped button for the user's thumb to press, but is not limited to this. It can also be any shape with a certain operating area, such as a sphere, a rectangular disc, an irregular shape, etc. The pusher 30 can be fixed to the end of the center rod 12 by screws, clamping or bonding. It is better to use a detachable structure. In this way, if the clamp 10 or the pulling structure 20 is damaged, it can be reused by disassembling the pusher 30 and replacing the corresponding components.

Please refer to FIG. 3 and FIG. 4 further. FIG. 3 is a schematic diagram of a clamping device clamping an object according to an embodiment of the present disclosure. FIG. 4 is a schematic diagram of a hand applying force to the clamping device to release an object according to an embodiment of the present disclosure. FIG. 3 shows an object 90 being clamped by the clamping device 100. At this time, the claws 131 of the two clamping claws 13 clamp the object 90 to clamp and fix the object 90 to the clamping device 100. If the object 90 is to be released, the thumb of one hand can be placed on the push member 30, and the index finger and middle finger can be placed on the upper and lower sides of the hollow sleeve 21 and against the operating member 23. The operating member 23 is adapted to drive the two pulling members 22 to pull the two clamping claws 13 based on the force received to move toward the push member 30, so that the two clamping claws 13 are elastically deformed and the two claws 131 release the object 90. As shown in FIG4, when the user applies force to the three fingers and brings the thumb, index finger and middle finger closer to each other, the operating member 23 will receive the force to move toward the push member 30, and drive the two pulling members 22 to pull the two clamping claws 13, so that the two claws 131 of the two clamping claws 13 are elastically deformed and can release the object 90.

Then, if you want to put the object 90 in again, you can repeat the above operation to open the two claws 131 of the two clamping claws 13 and let the two claws 131 open outward. In this way, the object 90 can be placed between the claws 131 of the two clamping claws 13 again. Then, as shown in Figure 3, after the user's three fingers stop applying force, the two clamping claws 13 will return to the initial position driven by the elastic restoring force, and the claws 131 will clamp the object 90 to clamp the object 90 in the clamping device 100. If you want to release the object 90, you can repeat the action of Figure 4.

Thus, the user can release or assemble the object 90 by holding the clamping device 100 with one hand. And because the pulling member 22 pulls the clamping claw 13 with a certain length, it is not necessary to apply too much force to easily make the two clamping claws 13 elastically deform and open. And the clamping device 100 has a small number of parts, and most of them can be made by plastic injection molding, making the manufacturing and assembly more convenient and reducing costs. In addition, the clamp 10, the pulling structure 20 and the pushing member 30 can be easily disassembled and assembled. If part of them is damaged, a single component can be replaced.

In some other embodiments, please refer to Figures 1 and 2 again. The clamping device 100 further includes a fixed bracket 40 clamped on the center rod 12 and located between the push member 30 and the operating member 23. After the object 90 is assembled to the clamp 10, the clamp 10 can be mounted on the fixed bracket 40 to be suitable for different usage scenarios. For example, the other end of the long rod of the fixed bracket 40 can be fixed to the car suction cup structure and can be adsorbed on the windshield for use. Or it can be fixed to the clamping structure, the tripod structure and can be fixed on the desktop for use. It can also be fixed to the motorcycle faucet locking structure and fixed to the motorcycle for navigation.

As shown in FIG. 2 , the fixed bracket 40 has a support rod 41, a clamping groove 42 and two positioning members 43. The support rod 41 is connected to the clamping groove 42, and the two positioning members 43 extend and protrude from two sides of the clamping groove 42. As shown in FIG. 1 , the center rod 12 is accommodated in the clamping groove 42, and the two positioning members 43 are clamped on two sides of the operating member 23. In this embodiment, the clamping groove 42 is in a U-shape that opens upward. When the object 90 is assembled to the clamp 10, the pulling structure 20 returns to the initial position. As shown in FIG. 3 , a gap will be formed between the center rod 12 and the operating member 23 and the push member 30. At this time, the U-shaped clamping groove 42 can be set upward from the bottom of the center rod 12 so that the center rod 12 is accommodated in the clamping groove 42. At the same time, when the fixed bracket 40 moves upward to clamp the clamping groove 42 on the center rod 12, the two positioning members 43 will move upward along the left and right sides of the operating member 23 and just clamp on the two sides of the operating member 23. Since the distance between the two positioning members 43 can just limit the operating member 23, the operating member 23 cannot rotate relative to the fixed bracket 40. In this way, the center rod 12 assembled in the clamping groove 42 can be prevented from rotating relative to the clamping groove 42 and changing the setting direction of the clamp 10.

Please further refer to Figures 2 and 5. Figure 5 is a three-dimensional view of the clamp of an embodiment of the present disclosure after being rotated 90 degrees from Figure 1. As can be seen from Figure 2, one side of the operating member 23 has two positioning grooves 231. When the clamp 10 is rotated to the point where the two positioning grooves 231 of the operating member 23 face the two positioning members 43 (i.e., the lower side as shown in Figure 5), the two positioning members 43 are correspondingly accommodated in the two positioning grooves 231. When the user wants to rotate the clamp 10 to use it horizontally, since the width of the operating member 23 when it is turned horizontally may be greater than the width when it is vertical, the two positioning members 43 will not be able to clamp on the two sides of the operating member 23, thereby limiting the rotation of the clamp 10 relative to the fixed bracket 40. To this end, this problem can be solved by providing two positioning grooves 231 on the side of the operating member 23. The distance between the two positioning grooves 231 can be approximately equal to the distance between the two positioning members 43, so that when the fixing bracket 40 is assembled upward, the two positioning members 43 can be exactly aligned and accommodated in the two positioning grooves 231. In this way, the center rod 12 assembled in the clamping groove 42 can be prevented from rotating relative to the clamping groove 42 and changing the setting direction of the clamp 10.

Please continue to refer to Figures 1 and 2. The clip slot 42 includes a receiving portion 421 and a neck portion 422. The neck portion 422 is located at one end of the receiving portion 421. The center rod 12 passes through the neck portion 422 and is received in the receiving portion 421. The arrangement of the neck portion 422 makes it difficult for the center rod 12 to pass through the receiving portion 421. Only when the user applies a certain force can the center rod 12 pass through the neck portion 422, thereby increasing the stability of the clamping on the fixed bracket 40.

Next, as can be seen from Figures 1 and 2, the clamp 10 further includes two limiters 14 connected to the other two sides of the base 11 relative to the two clamping claws 13. In other words, if the two clamping claws 13 are extended in the up-down direction, the two limiters 14 are extended in the left-right direction. The two limiters 14 can be L-shaped plates with a fixed spacing, or L-shaped plates with adjustable spacing. This provides the object 90 with a clamping force in the other two directions, making the clamping of the object 90 more stable.

As can be seen from FIG. 2 , the operating member 23 includes two extension plates 232, one end of each extension plate 232 is connected to the hollow sleeve 21, and the other end extends in a direction perpendicular to the hollow sleeve 21. Each extension plate 232 forms an operating plane sufficient for a finger to lean against, so as to improve operability. Furthermore, the operating member 23 further includes two protrusions 233, which are respectively arranged at the other end of the extension plate 232 and extend in a direction parallel to the hollow sleeve 21. In this way, the finger can be provided with a stop limit function to prevent the finger from coming out from the two ends of the extension plate 232 during the process of pressing hard, so as to cause the pulling structure 20 to bounce back.

In summary, the user can hold the clamping device 100 with one hand, place the thumb on the push member 30, and then place the index finger and the middle finger on the operating member 23 to perform the release operation. After applying the force, the operating member 23 will be driven to move toward the push member 30, thereby driving the two pulling members 22 to pull the two clamping claws 13, causing the two clamping claws 13 to elastically deform and make the two claws 131 open. When the two clamping claws 13 are elastically deformed and opened, the object 90 is released, and the user can remove the object 90. In this way, the two clamping claws 13 can be easily deformed and opened to release or clamp the object 90 again by one-hand operation without applying too much force. Furthermore, the clamping device 100 as a whole requires a small number of parts, and most of them can be manufactured through plastic injection molding, making manufacturing and assembly more convenient and reducing costs.
