Description

Support frame

The present invention relates to a support frame, and more particularly to a support frame for supporting an electronic device.

With the advancement of technology, portable electronic devices such as smart phones or tablets that have the functions of watching movies, browsing the web or playing games have become an indispensable tool in modern life. In the case of a tablet computer, in order to provide a more comfortable viewing angle for the user, the tablet is usually provided with a support frame, and the support frame can be pivoted and unfolded relative to the tablet computer, and the user can view the viewing angle according to the desired angle. Place the tablet on a flat surface (such as a desktop) at different degrees of inclination.

However, such a design still has deficiencies, for example, when the support frame is pivoted relative to the tablet to the stop positioning point of the tablet, the support frame is at a maximum angle relative to the tablet opening. In this case, if the user forgets that the support frame has been opened to the maximum angle and continues to press the tablet, the support frame is susceptible to external force and causes bending deformation near the stop positioning point. When the support frame is bent and deformed, it can no longer be flattened on the tablet computer and affects the overall appearance.

In addition, in this case, if the user's finger is placed between the support frame and the tablet computer inadvertently, the accident that the finger is pinched by the support frame may occur inadvertently.

The invention provides a support frame, which solves the problem that the support frame is easily bent and deformed by external force when it abuts against the stop positioning point, and reduces the probability of the finger being inadvertently caught by the support frame.

A support frame disclosed in the present invention is used to support an electronic device. The bracket includes at least one first frame body, at least one second frame body, at least one first pressing block and at least one second pressing block. At least one first frame has a first surface. The first frame is used for pivoting to the electronic device. At least one second frame has a second surface. The second surface faces the first surface. The second frame is pivotally connected to the first frame. At least one first pressing block is fixed to the first surface. At least one second pressing block is disposed on the second surface. The at least one first pressing block is detachably pressed against the at least one second pressing block. When the at least one first pressing block is pressed against the at least one second pressing block, the at least one second frame body and the at least one first frame body are fixed to each other. When the at least one first pressing block slides relative to the at least one second pressing block, the at least one second frame rotates relative to the at least one first frame.

A support frame disclosed in the present invention is used to support an electronic device. The bracket includes at least one first frame body, at least one second frame body and at least one first pressing block. At least one first frame has a first surface. The first frame is used for pivoting to the electronic device. At least one second frame has a second surface. The second surface faces the first surface. The second frame is pivotally connected to the first frame. The at least one first pressing block is fixed to one of the first surface and the second surface, and is slidably pressed against the other of the first surface and the second surface to enable the at least one second frame and the at least one first The frame can be rotated synchronously with respect to the electronic device. When an external force is applied to one of the support frame and the electronic device, and the external force overcomes the static friction force of the at least one first pressing block against the second surface, the at least one second frame rotates relative to the at least one first frame .

In the support frame disclosed by the present invention, by providing a pressing block between the first frame and the second frame, static friction can be generated between the first frame and the second frame, so that the support frame is A reasonable range of pivoting is normally used, but the second frame and the first frame are relatively pivoted when the support frame is pivoted to a maximum angle relative to the electronic device or is pressed by a large external force to avoid bending the support frame. The situation of deformation occurs. In addition, the chance of a finger being accidentally pinched by the support frame can also be reduced.

And the first pivot axis A1 and the second pivot axis A2 are non-coaxial. The third frame body 30 is connected between the two second frame bodies 20. The second frame body 20 is connected to the electronic device 9 via the two first frame bodies 10 , and the third frame body 30 is connected to the first frame body 10 via the second frame body 20 .

In addition, in the present embodiment, the third frame body 30 and the second frame body 20 are integrally formed and together form a U-shaped structure, but are not intended to limit the present invention. For example, in other embodiments, the second frame 20 and the third frame 30 can be separate components. In addition, it should be stated first that the number of the first frame body 10 and the second frame body 20 is not intended to limit the present invention. For example, in other embodiments, the support frame may include only a single first frame 10 and a single second frame 20. In this case, the support frame can omit the third frame body 30.

Next, as shown in FIG. 3, the first frame body 10 and the second frame body 20 in which a pair of phases are pivotally connected will be described. In this embodiment, the support frame 1 further includes a plurality of first pressing blocks 110 and a plurality of second pressing blocks 210. Specifically, the first frame 10 has a first surface 11, and the second frame 20 has a second surface 21, and the first surface 11 and the second surface 21 refer to the first frame 10 and the second frame, respectively. The two first pressing blocks 110 are disposed on the first surface 11 of the first frame body 10, and the two second pressing blocks 210 are disposed on the second surface 21 of the second frame body 20, And the two first pressing blocks 110 correspond to the two second pressing blocks 210 respectively. In the embodiment, the first pressing block 110 is integrally formed with the first frame body 10, and the second pressing block 210 and the second frame body 20 are integrally formed.

More specifically, in the present embodiment, the first pressing block 110 and the second pressing block 210 are slightly trapezoidal in shape, and each of the first pressing blocks 110 has a first abutting surface 111 and is connected to Two first guiding slopes 113 on opposite sides of the first abutting surface 111, each of the second pressing blocks 210 has a second abutting surface 211 and two opposite sides of the second abutting surface 211 The second guiding surface 213 of the first pressing block 110 corresponds to the second abutting surface 211 of the second pressing block 210 .

In the present embodiment, the pivot 40 is located between the two first pressing blocks 110. It can also be said that the pivot 40 is located between the two second pressing blocks 210. The first frame 10 and the second frame 20 are pivoted relative to each other, and the two first abutting faces 111 of the first pressing block 110 are slidably pressed against the second pressing blocks 210, respectively. Two second abutting faces 211.

Next, as shown in FIG. 4A, in the case where the first pressing block 110 is separated from the second pressing block 210, that is, the first abutting surface 111 of the first pressing block 110 is not pressed against the second pressing. When the second abutting surface 211 of the block 210 is located, the first abutting surface 111 of the first pressing block 110 is separated from the first surface 11 by a distance D1, and the second abutting surface 211 of the second pressing block 210 is second and second. The surfaces 21 are separated by a distance D2, the first surface 11 is spaced apart from the second surface 21 by a distance D3, and the sum of the distance D1 and the distance D2 is greater than the distance D3.

The first frame body 10 and the second frame body 20 are pivoted relative to each other, for example, pivoting the second frame body 20 in the pivoting direction T, and one of the second guiding slopes 213 of the second pressing block 210 is slidable. And pushing against one of the first guiding slopes 113 of the first pressing block 110, as shown in FIG. 4B, guiding the first abutting surface 111 of the first pressing block 110 against the second abutting The second abutting surface 211 of the pressing block 210. Since the sum of the above distance D1 and the distance D2 is greater than the distance D3. Therefore, the distance between the first frame 10 and the second frame 20 can be slightly extended by the first pressing block 110 and the second pressing block 210, whereby the first abutting surface 111 and the first The two abutting faces 211 will abut against each other to generate a static friction force. It can be understood that the shape and size of the pressing block are not used to limit the present invention, and the user can control the required static friction between the first frame 10 and the second frame 20 by adjusting the size of the pressing block. . Of course, the magnitude and relative size of the distance D1 and the distance D2 may be different according to the sizes of the first pressing block 110 and the second pressing block 210, respectively, and are not intended to limit the present invention.

Next, the manner of use of the support frame 1 will be described. 5A-7B, FIG. 5A is a schematic view showing a state of use of the support frame according to the first embodiment of the present invention, and FIG. 5B is a schematic view of the support frame of FIG. 5A according to the present invention being pushed by an external force. 6 is a schematic view showing a state in which the support frame is extended to a maximum angle with respect to the electronic device according to the first embodiment of the present invention, and FIG. 7A is a schematic view of the electronic device of FIG. 6 according to the present invention being pushed by an external force, and FIG. 7B is a schematic diagram of FIG. A partial enlarged view of the support frame of Fig. 7A in accordance with the present invention. It is to be noted that, for the purpose of clarity of illustration, the viewing angles of Figures 5B and 7B are opposite to the viewing directions of Figures 5A and 7A, respectively.

First, as shown in FIG. 5A, the user can relatively unfold the support frame 1 to place the electronic device 9 on the plane G. In this case, the electronic device 9 can be steeply supported by the support of the support frame 1. The method is placed on a plane, as shown in the figure, a first angle θ1 is sandwiched between the electronic device 9 and the plane G. Then, if the user wants to adjust the electronic device 9 to be relatively flat to fit the desired viewing angle, the usage habit is usually directly pushed to the electronic device 9. For example, the user can directly push the electronic device 9. In this case, the plane G generates an external force F1 on the second frame 20 of the support frame 1 to push against the second frame 20, as shown in FIG. 5B, but The moment generated by the external force F1 for the pivot 40 is less than or equal to the moment generated by the static friction between the first pressing block 110 and the second pressing block 210 on the pivot 40, so that the first pressing block 110 and the second abutting The pressure blocks 210 are fixed to each other. Therefore, the second frame 20 that is pushed up can drive the relative electronic device 9 of the first frame 10 to pivot to the desired position, that is, the second frame 20 and the first frame 10 are opposite to the electronic device 9 Synchronous rotation.

Then, as shown in FIG. 6 , the user can pivot the support frame 1 relative to the electronic device 9 to a maximum angle to place the electronic device 9 on the plane G in a relatively flat manner, as shown in the figure, the electronic device. A second angle θ2 smaller than the first angle θ1 is sandwiched between the plane 9 and the plane G. In this case, the user can continue to operate the electronic device 9 in the manner of the touch electronic device 9, that is, the electronic device 9 is continuously pressed with the finger.

However, when the user applies excessive force to the electronic device 9 or even the support frame 1 itself, as shown in FIGS. 7A-7B, the second frame 20 is relatively pivoted relative to the first frame 10. Specifically, when the force applied by the user to the electronic device 9 is too large, the plane G generates an excessive external force F2 to the second frame 20 of the support frame 1, that is, the external force F2 generates a greater torque for the pivot 40. The static friction force between the first pressing block 110 and the second pressing block 210 generates a moment to the pivot 40. In this case, the external force F2 has caused the second frame 20 to overcome the first pressing block 110. The static friction between the second pressing block 210 and the second pressing block 210 causes the first pressing block 110 to slide away from the second pressing block 210 to disengage from each other, so that the second frame 20 is opposite to the first frame 10 Pivot. Thereby, it is possible to avoid a situation in which the support frame 1 is easily stretched and deformed when it is deployed to a maximum angle or subjected to an excessive external force.

From the above, it can be understood that the number of the pressing blocks is optional, as long as the first frame body 10 and the second frame body 20 are relatively opened to generate a threshold static friction design. The scope of the invention. That is, the number of the first pressing block 110 on each of the first frame bodies 10 and the second pressing block 210 on each of the second frame bodies 20 is not intended to limit the present invention, and may be performed according to the needs of the user. The amount of adjustment.

For example, referring to FIGS. 8A-8B, FIG. 8A is a first pressing block of the support frame according to the second embodiment of the present invention, which is not pressed against the second frame body and the second pressing block is not pressed against the first frame. A partial enlarged view of the body, and FIG. 8B is a partial enlargement of the first pressing block of the support frame according to the second embodiment of the present invention against the second frame body and the second pressing block against the first frame body. schematic diagram. It is to be noted that, for the sake of brevity and clarity, the contents of the support frame of the present embodiment are only described in terms of differences from the foregoing embodiments, and the similarities with the foregoing embodiments are not described herein.

As shown in the figure, the first frame body 10 and the second frame body 20 in which one of the groups is pivotally connected is taken as an example. In this embodiment, only a first pressing block 110 is disposed on the first surface 11 of each first frame body 10, and only a second pressing force is disposed on the second surface 21 of each second frame body 20. Block 210. The first abutting surface 111 of the first pressing block 110 is slidably pressed against the second surface 21 , and the second abutting surface 211 of the second pressing block 210 is slidably pressed against the first surface 11 . . When the first abutting surface 111 of the first pressing block 110 does not press against the second surface 21 and the second abutting surface 211 of the second pressing block 210 does not press against the first surface 11, the first abutting The distance D4 between the junction 111 and the first surface 11 and the distance D5 between the second abutment surface 211 and the second surface 21 are equal and greater than the distance D6 between the first surface 11 and the second surface 21. The first abutting surface 111 of the first pressing block 110 is pressed against the second surface 21 and the second abutting by pivoting the second frame 20 in the pivoting direction T relative to the first frame body 10, for example. The second abutting surface 211 of the pressing block 210 is pressed against the first surface 11 to generate a static frictional force. Therefore, similar to the manner of use of the foregoing embodiment, when the external force applied to the second frame 20 does not cause the second frame 20 to not overcome the first pressing block 110 against the second surface 21 and the second pressing block 210 When the static friction force generated by the first surface 11 is pressed, the second frame 20 pushed by the force can drive the first frame 10 to rotate relative to the electronic device 9, that is, the second frame 20 and the first frame 10 It can rotate synchronously with respect to the electronic device 9. However, when the external force overcomes the static friction force generated by the first pressing block 110 against the second surface 21 and the second pressing block 210 against the first surface 11, the second frame 20 can be made relative to the first frame. The body 10 rotates.

9A to 9B, FIG. 9A is a partially enlarged schematic view of the first pressing block of the support frame according to the third embodiment of the present invention, which is not pressed against the second frame body, and FIG. 9B is a schematic view according to the present invention. The first pressing block of the support frame of the third embodiment is pressed against a partial enlarged view of the second frame. As shown in the figure, the first frame body 10 and the second frame body 20 in which one of the groups is pivotally connected is taken as an example. In this embodiment, only one first pressing block 110 is disposed on the first surface 11 of each first frame body 10, but no pressing block is disposed on the second frame body 20. In this case, the first abutting surface 111 of the first pressing block 110 is slidably pressed against the second surface 21, and the first abutting surface 111 of the first pressing block 110 is not pressed against the first surface. When the two surfaces 21 are different, the distance D7 between the first abutting surface 111 and the first surface 11 is greater than the distance D8 between the first surface 11 and the second surface 21. The first abutting surface 111 of the first pressing block 110 can be pressed against the second surface 21 to generate static friction force by pivoting the second frame 20 in the pivoting direction T relative to the first frame body 10, for example. . Therefore, similar to the manner of use of the foregoing embodiment, when the force applied to the second frame body 20 does not cause the second frame body 20 to overcome between the first abutting surface 111 of the first pressing block 110 and the second surface 21 When the static friction is generated, the second frame 20 and the first frame 10 are synchronously rotated with respect to the electronic device 9. However, when the external force overcomes the static friction generated by the first abutting surface 111 of the first pressing block 110 against the second surface 21, the second frame 20 can be rotated relative to the first frame 10.

Therefore, it is to be understood that the present invention is not limited to the position at which the first pressing block 110 is disposed. For example, in other embodiments, the first pressing block 110 can be disposed on the second surface 21 of the second frame 20 .

In summary, the support frame of the present invention can form a static friction force between the first frame body and the second frame body by providing a pressing block between the first frame body and the second frame body, so as to allow The support frame is normally used within a reasonable pivoting range, but the second frame body and the first frame body are relatively pivoted when the support frame is pivoted to a maximum angle relative to the electronic device or is pressed by a large external force to avoid causing The situation in which the support frame is bent and deformed occurs. In addition, the chance of a finger being accidentally pinched by the support frame can also be reduced.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. It is within the scope of the invention to be modified and modified without departing from the spirit and scope of the invention. Please refer to the attached patent application for the scope of protection defined by the present invention.
