## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a support bracket and, more particularly, to a support bracket allowing a user to attach/detach an electronic device thereto/therefrom rapidly.
2. Description of the Prior Art
As technology advances and develops, various electronic devices, such as mobile phone, personal digital assistant, tablet computer, and so on, have been used in daily life widely. Under some situations, a user may place the electronic device on a support frame, such that an appropriate operation/viewing angle is formed between the electronic device and the user. In general, the electronic device is fixed on the conventional support frame by a screwed manner. However, it is complicated and inconvenient for the user to attach/detach the electronic device to/from the conventional support frame by the screwed manner. Furthermore, if the user cannot find a suitable screwdriver provisionally, he/she cannot attach/detach the electronic device to/from the conventional support frame accordingly.
SUMMARY OF THE INVENTION
The invention provides a support bracket allowing a user to attach/detach an electronic device thereto/therefrom rapidly, so as to solve the aforesaid problems.
According to an embodiment of the invention, a support bracket comprises a housing, a driving member, a first linking member, a gear mechanism, a first engaging member, a second linking member and a second engaging member. The housing has a guiding rail and a through hole, and the guiding rail is located in the housing. The driving member is movably disposed in the housing and has a driving portion and a first rack portion, and the driving portion is exposed out of the housing. The first linking member is movably disposed in the housing and has a second rack portion and an engaging groove. The gear mechanism is disposed in the housing and meshes with the first rack portion and the second rack portion. The first engaging member is movably disposed in the housing and has a guiding portion and a first engaging portion, and the guiding portion is disposed in the guiding rail. The second linking member is disposed in the housing, and opposite ends of the second linking member are pivotally connected to the first linking member and the first engaging member, respectively. The second engaging member is rotatably disposed in the housing and has a second engaging portion. Before the driving portion is pressed, the first engaging portion is retracted into the housing from the through hole. When the driving portion is pressed, the driving member drives the first engaging member to move along the guiding rail through a cooperation between the first rack portion, the gear mechanism, the second rack portion and the second linking member, such that the first engaging portion protrudes out of the housing from the through hole and the second engaging portion is engaged with the engaging groove.
In this embodiment, the support bracket may further comprise a button and a first resilient member. The button is movably disposed in the housing and used for pushing the second engaging member to rotate, so as to disengage the second engaging portion from the engaging groove. Opposite ends of the first resilient member are connected to the housing and the driving member, respectively. When the second engaging portion is disengaged from the engaging groove, the first resilient member generates an elastic force for pulling the driving member to move. Afterwards, the driving member drives the first engaging member to move along the guiding rail through a cooperation between the first rack portion, the gear mechanism, the second rack portion and the second linking member, such that the first engaging portion is retracted into the housing from the through hole.
As mentioned in the above, when a user wants to attach the electronic device to the support bracket, he/she only needs to press the driving portion of the driving member by the bottom of the electronic device. Consequently, the first engaging portion of the first engaging member protrudes out of the housing from the through hole and then is engaged with an engaging groove on a back of the electronic device. Accordingly, the user can attach the electronic device to the support bracket rapidly. Furthermore, when the user pushes the button, the first engaging portion of the first engaging member is disengaged from the engaging groove on the back of the electronic device and then retracted into the housing from the through hole. Accordingly, the user can detach the electronic device from the support bracket rapidly. In other words, the support bracket of the invention allows the user to attach/detach the electronic device thereto/therefrom rapidly without any tools and is very convenient in operation.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

Opposite ends of the third resilient member 40 are connected to the housing 10 and the lock member 36, respectively. In this embodiment, the third resilient member 40 may be a spring, but not limited to the spring.
Referring to FIGS. 7 to 12 at the same time, FIG. 7 is a rear perspective view illustrating an electronic device 5 capable of being attached to the support bracket 1 shown in FIG. 1, FIG. 8 is a front perspective view illustrating the electronic device 5 shown in FIG. 7 being attached to the support bracket 1 shown in FIG. 1, FIG. 9 is a front perspective view illustrating the driving portion 120 of the support bracket 1 shown in FIG. 1 being pressed, FIG. 10 is a rear perspective view illustrating the support bracket 1 shown in FIG. 1 without the back cover 102, FIG. 11 is a front perspective view illustrating the inner components shown in FIG. 10, and FIG. 12 is a perspective view illustrating the second engaging member 22 and the first linking member 14 shown in FIG. 11 being engaged with each other.
As shown in FIG. 7, the bottom of the electronic device 5 has two positioning holes 50 and a connecting port 52 and the back of the electronic deice 5 has two engaging grooves 54, wherein the two positioning holes 50 are corresponding to the two positioning pillars 32 of the support bracket 1, the connecting port 52 is corresponding to the electric connector 34 of the support bracket 1, and the two engaging grooves 54 are corresponding to the two through holes 106 of the support bracket 1. As shown in FIG. 1, before the driving portion 120 is pressed, the first engaging portion 182 is retracted into the housing 10 from the through hole 106. When a user wants to attach the electronic device 5 to the support bracket 1, he/she needs to align/insert the two positioning pillars 32 and the electric connector 34 of the support bracket 1 with/into the two positioning holes 50 and the connecting port 52 on the bottom of the electronic device 5 and then pushes the driving portion 120 by the bottom of the electronic device 5. After inserting the two positioning pillars 32 and the electric connector 34 into the two positioning holes 50 and the connecting port 52, the two engaging grooves 54 on the back of the electronic device 5 are aligned with the two through holes 106 of the support bracket 1. The electronic device 5 can communicate with the electric connector 34 through the connecting port 52, so as to transmit signals.
In the following, FIGS. 1, 5, 6 and 9-12 are used to depict the operation principle of the support bracket 1 of the invention, wherein FIGS. 1, 5 and 6 illustrate that the position relation between the components before the driving portion 120 is pressed and FIGS. 9-11 illustrate that the position relation between the components after the driving portion 120 is pressed. When the driving portion 120 is pressed, the driving member 12 will move downwardly, such that the first rack portion 122 drives the gear mechanism 16 to rotate. Afterwards, the second gear 162 of the gear mechanism 16 cooperates with the second rack portion 140 to drive the first linking member 14 to move downwardly. Then, the second linking member 20 is driven by the first linking member 14 to move, so as to drive the first engaging member 18 to move along the guiding rail 104, such that the first engaging portion 182 protrudes out of the housing 10 from the through hole 106. In other words, when the driving portion 120 is pressed, the driving member 12 drives the first engaging member 18 to move along the guiding rail 104 through a cooperation between the first rack portion 122, the gear mechanism 16, the second rack portion 140 and the second linking member 20, such that the first engaging portion 182 protrudes out of the housing 10 from the through hole 106. Finally, the two first engaging portions 182 enter the two engaging grooves 54 on the back of the electronic device 5, so as to fix the electronic device 5 on the support bracket 1.
After the driving portion 120 is pressed, the first resilient member 24 is stretched. Furthermore, the first linking member 14 will push the second engaging portion 220 of the second engaging member 22 while moving downwardly, such that the second engaging member 22 will rotate away from the first linking member 14 and the torsion spring 42 is twisted. Then, the second engaging member 22 will rotate toward the first linking member 14 and return to the original position due to a torque force generated by the torsion spring 42, such that the second engaging portion 220 is engaged with the engaging groove 142 of the first linking member 14, as shown in FIG. 12. Accordingly, it can be ensured that all of the components will not move or rotate with respect to each other. In this embodiment, the linking rod 30 enables the driving member 12 to move upward and downward smoothly without inclination.
In this embodiment, a number of teeth of the first gear 160 may be larger than a number of teeth of the third gear 164, such that a moving distance of the first engaging member 18 may be larger than a moving distance of the driving member 12. For example, if the number of teeth of the first gear 160 is 16 and the number of teeth of the third gear 164 is 8 the moving distance of the first engaging member 18 is twice as long as the moving distance of the driving member 12. In other words, the invention may change the gear ration between the first gear 160 and the third gear 164 to adjust the related moving distances of the first engaging member 18 and the driving member 12.
Referring to FIG. 13, FIG. 13 is a perspective view illustrating the button 26 shown in FIG. 12 being pressed. When the user wants to detach the electronic device 5 from the support bracket 1, the user only needs to push the button 26, so as to push the second engaging member 22 to rotate away from the first linking member 14, such that the second engaging portion 220 is disengaged from the engaging groove 142. At this time, the stretched first resilient member 24 generates an elastic force for pulling the driving member 12 upwardly. Then, the driving member 12 drives the first engaging member 18 to move along the guiding rail 104 through the cooperation between the first rack portion 122, the gear mechanism 16, the second rack portion 140 and the second linking member 20, such that the first engaging portion 182 is ejected out of the engaging groove 54 on the back of the electronic device 5 and retracted into the housing 10 from the through hole 106. At this time, the user can detach the electronic device 5 from the support bracket 1. As mentioned in the above, the second engaging member 22 can rotate toward the first linking member 14 and return to the original position due to the torque force generated by the torsion spring 42. Similarly, after removing the press force from the button 26, the button 26 will return to the original position due to the elastic force generated by the second resilient member 28.
Referring to FIG. 14, FIG. 14 is a perspective view illustrating the lock member 36 and the lock recess 124 of the driving member 12 shown in FIG. 11 being engaged with each other. In this embodiment, after the driving portion 120 is pressed, the rotating member 38 can be rotated to push the lock member 36 to move toward the lock recess 124, such that the lock member 36 is engaged with the lock recess 124, as shown in FIG. 14. In this embodiment, the back cover 102 has a lock hole 108 and one end of the rotating member 38 is located in the lock hole 108. The user can insert a key (not shown) into the lock hole 108 to rotate the rotating member 38, so as to engage the lock member 36 with the lock recess 124. After the lock member 36 is engaged with the lock recess 124, the driving member 12 cannot move upwardly. At this time, the user cannot press the button 26 to eject the first engaging portion 182 out of the engaging groove 54 on the back of the electronic device 5. Accordingly, the invention can prevent the electronic device 5 from being stolen. After the lock member 36 is engaged with the lock recess 124, the third resilient member 40 is stretched. The user can use the aforesaid key to rotate the rotating member 38 away from the lock member 36, such that the third resilient member 40 generates an elastic force for pulling the lock member 36 to move upwardly, so as to disengage the lock member 36 from the lock recess 124. At this time, the user can press the button 26 to eject the first engaging portion 182 out of the engaging groove 54 on the back of the electronic device 5 and then detach the electronic device 5 from the support bracket 1.
As mentioned in the above, when a user wants to attach the electronic device to the support bracket, he/she only needs to press the driving portion of the driving member by the bottom of the electronic device. Consequently, the first engaging portion of the first engaging member protrudes out of the housing from the through hole and then is engaged with an engaging groove on a back of the electronic device. Accordingly, the user can attach the electronic device to the support bracket rapidly. Furthermore, when the user pushes the button, the first engaging portion of the first engaging member is disengaged from the engaging groove on the back of the electronic device and then retracted into the housing from the through hole. Accordingly, the user can detach the electronic device from the support bracket rapidly. In other words, the support bracket of the invention allows the user to attach/detach the electronic device thereto/therefrom rapidly without any tools and is very convenient in operation.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
