[0029] like Figure 1-8 As shown, a support frame capable of realizing signal transmission is used to clamp and support a three-proof mobile terminal, such as a three-proof tablet computer. The support frame includes a base 1, a back panel 2 and a locking box. The back panel 2 is respectively locked with the locking box and the base 1 by screws, and the back panel 2 can be removed by removing the connecting screws. In actual use, the user can replace the back panel 2 of different sizes as needed, so that it can be used for three-proof tablet computers of different sizes, thereby improving versatility. A limiting mechanism is provided on the base 1, and the limiting mechanism is used to limit one of the sides of the three-proof mobile terminal. The limiting mechanism is provided with a conductive member 3, and the conductive member 3 is used for detachable electrical connection with the three-proof mobile terminal. An output connector 4 is provided on the base 1, and the conductive member 3 is electrically connected to the output connector 4. The output connector 4 can be used for external devices to realize high-definition signal transmission, and can also be used for external power supply to charge the three-proof mobile terminal.

[0030] In this embodiment, the conductive member 3 is a pogo pin, and contact electrodes are provided at positions corresponding to the conductive member 3 on the triple-proof mobile terminal; the conductive member 3 is connected to the contact electrodes, so that the triple-proof mobile terminal and the base 1 are electrically connected.

[0031] The locking box includes a fixing box 5, which is connected to the back plate 2 by screws, and a locking buckle 6 is provided on the fixing box 5, and the locking buckle 6 is connected to the fixing box 5 in a telescopic limit manner, and a locking block 7 is provided on the locking buckle 6, and the locking buckle 6 can drive the locking block 7 to abut or separate from a side of the three-proof mobile terminal away from the limit mechanism. Specifically, when it is necessary to lock the three-proof mobile terminal, the user can press the locking buckle 6 to extend it into the fixing box 5, and the locking buckle 6 will drive the locking block 7 to move together, so that it is clamped and fixed with one end of the three-proof mobile terminal away from the limit mechanism, and the two ends of the three-proof mobile terminal are clamped by the locking block 7 and the limit mechanism, so that the three-proof mobile terminal is limited and fixed on the support frame, so as to achieve the purpose of clamping and supporting the three-proof mobile terminal; when it is necessary to release the three-proof mobile terminal, it is only necessary to pull out the locking buckle 6 to extend it out of the fixing box 5, and the locking buckle 6 will drive the locking block 7 to separate from the three-proof mobile terminal, and the user can take out the three-proof mobile terminal from the base 1.

[0032] When using the support frame, the three-proof mobile terminal is placed on the base 1, so that the output probe on the three-proof mobile terminal is aligned with the conductive piece 3, and the two are connected, so that the three-proof mobile terminal and the base 1 are electrically connected; then, by pressing the locking buckle 6, the locking buckle 6 is retracted into the fixing box 5, and the locking buckle 6 drives the locking block 7 to move toward the base 1, and the locking block 7 will abut against the end of the three-proof mobile terminal away from the base 1; thereby, the three-proof mobile terminal is fixed on the support frame through the locking block 7 and the limiting mechanism; the three-proof mobile terminal is electrically connected to the conductive piece 3 stably, and then the output connector 4 on the base 1 can be connected to an external device such as a projector, so that the three-proof mobile terminal can achieve stable high-definition signal transmission through the support frame. The support frame can clamp and fix the triple-proof mobile terminal through the cooperation of the limiting mechanism and the locking buckle 6, so that it is stably electrically connected to the base 1, which is convenient for charging with an external power supply and can also achieve stable high-definition signal transmission, thereby improving versatility and meeting the use of some scenarios that require signal transmission, such as conference projection and other scenarios.

[0033] A contact block 21 is provided on the back plate 2, and the contact block 21 is used to support the back of the triple-proof mobile terminal; after the triple-proof mobile terminal is placed on the base 1, the contact block 21 can contact the back of the triple-proof mobile terminal, and the back of the triple-proof mobile terminal is pressed against by the contact block 21, so that it can be placed more stably on the support frame, thereby improving the working stability of the support frame.

[0034] The fixing box 5 is provided with a limit block 51, and the locking buckle 6 is provided with an unlocking component, and the unlocking component is detachably connected to the limit block 51. When the locking buckle 6 is retracted into the fixing box 5 so that the locking block 7 is clamped and fixed with the three-proof mobile terminal, the unlocking component is clamped and fixed with the limit block 51, so that the locking buckle 6 is limitedly connected with the fixing box 5 through the cooperation of the unlocking component and the limit block 51, ensuring that the locking buckle 6 will not automatically extend out of the fixing box 5, thereby improving the stability of the structure. The unlocking component can also be used to drive the locking buckle 6 to disengage from the fixing box 5. By operating the unlocking component, the unlocking component can be disengaged from the limit block 51, so that the locking buckle 6 is separated from the fixing box 5; at this time, the locking buckle 6 can be extended from the fixing box 5 to remove the three-proof mobile terminal on the base 1.

[0035] Specifically, the unlocking assembly includes an unlocking member 8 and a sliding member 9. One end of the unlocking member 8 extends out of the locking buckle 6 and is slidably and position-limitedly connected to the locking buckle 6. The sliding member 9 is slidably and position-limitedly connected to the locking buckle 6. The sliding member 9 is detachably connected to the limit block 51. Two first elastic members 10 are provided on the locking buckle 6. The other end of the first elastic member 10 is connected to the sliding member 9. The unlocking member 8 is connected to one end of the sliding member 9 away from the first elastic member 10. The unlocking member 8 can drive the sliding member 9 to move in a direction away from the limit block 51. The first elastic member 10 is used to push the sliding member 9 to move in a direction close to the limit block 51; thereby, the sliding member 9 can be fixedly connected to the limit block 51. In the initial state, the sliding member 9 is separated from the limit block 51, and the sliding member 9 is located above the limit block 51; when the three-proof mobile terminal needs to be clamped, the user can push the unlocking member 8 to extend one end of the locking buckle 6 to move it toward the direction close to the first elastic member 10, and press the upper end of the locking buckle 6 downward; the unlocking member 8 will push the sliding member 9 to move toward the first elastic member 10, and the sliding member 9 compresses the first elastic member 10, while the locking buckle 6 drives the unlocking member 8 and the sliding member 9 to slide downward until the sliding member 9 passes over the limit block 51; then the user releases the unlocking member 8, and under the action of the elastic force of the first elastic member 10, the sliding member 9 and the unlocking member 8 will be pushed to move toward the direction close to the limit block 51 until the sliding member 9 is fixedly engaged with the limit block 51, and at this time, the locking buckle 6 also drives the locking block 7 to abut against the end of the three-proof mobile terminal away from the limit mechanism. Through the cooperation between the sliding member 9 and the limit block 51, the locking buckle 6 can be connected and fixed to the fixing box 5.

[0036] When it is necessary to take out the triple-proof mobile terminal, by pushing the unlocking piece 8 to extend out of one end of the locking buckle 6, the unlocking piece 8 will push the sliding piece 9 to move in the direction of the first elastic piece 10, and the sliding piece 9 compresses the first elastic piece 10 until the sliding piece 9 is disengaged from the limit block 51; at this time, the locking buckle 6 can be pulled out from the fixing box 5, so that the locking block 7 is disengaged from the triple-proof mobile terminal, so as to take out the triple-proof mobile terminal on the base 1.

[0037] In order to limit and guide the movement direction of the sliding member 9, two first guide grooves 91 are provided on the sliding member 9, and first guide blocks 61 are respectively provided at positions corresponding to the first guide grooves 91 on the locking buckle 6. The first guide blocks 61 extend into the corresponding first guide grooves 91 and are slidably connected with the first guide grooves 91. When the sliding member 9 is in motion, the first guide grooves 91 will slide on the first guide blocks 61. The cooperation between the first guide blocks 61 and the first guide grooves 91 can limit and guide the movement direction of the sliding member 9, thereby improving the stability and accuracy of the transmission. In other embodiments, the number of first guide blocks 61 and first guide grooves 91 can also be any other number.

[0038] A first inclined surface 92 is provided on the side wall of the sliding member 9 near the limit block 51, and a second inclined surface 52 is provided on the limit block 51 near the sliding member 9. The first inclined surface 92 can be slidably connected with the second inclined surface 52. In the initial state, the first inclined surface 92 is connected with the second inclined surface 52. In the process of pushing the locking member to move in the direction of the first elastic member 10 and pressing the locking buckle 6, the first inclined surface 92 will slide on the second inclined surface 52; through the cooperation of the first inclined surface 92 and the second inclined surface 52, the sliding process of the sliding member 9 is smoother, the stability of the transmission is improved, and it is ensured that the sliding member 9 can be smoothly engaged with the limit block 51.

[0039] Two second elastic members 11 are installed on the fixing box 5, and the other ends of the two second elastic members 11 are connected to the locking buckle 6 respectively. The two second elastic members 11 are symmetrically distributed on both sides of the locking buckle 6. The second elastic members 11 are used to push the locking buckle 6 out of the fixing box 5; by setting the second elastic members 11, the locking buckle 6 can automatically extend out of the fixing box 5 after being separated from the clamping limit of the limit block 51. In the initial state, the second elastic member 11 is in an open state; in the process of pressing the locking buckle 6 to make the locking block 7 clamp the triple-proof mobile terminal, the locking buckle 6 will compress the second elastic member 11. When it is necessary to remove the triple-proof mobile terminal from the support frame, the user can push the unlocking member 8 to extend one end of the locking buckle 6, and the unlocking member 8 will push the sliding member 9 to move in the direction of the first elastic member 10 until the sliding member 9 is disengaged from the limit block 51; at this time, the sliding member 9 is disengaged from the limit block 51, and the second elastic member 11 will release elastic potential energy, thereby pushing the locking buckle 6 to move upward, so that the locking block 7 is disengaged from the triple-proof mobile terminal, and then the triple-proof mobile terminal can be easily removed from the base 1.

[0040] In this embodiment, the first elastic member 10 and the second elastic member 11 are both coil springs; in other embodiments, the first elastic member 10 and the second elastic member 11 may also be replaced by other elastic structures or devices.

[0041] In order to limit the travel of the locking buckle 6 extending out of the fixed box 5, limiting protrusions 62 are respectively provided on the left and right sides of the locking buckle 6, and limiting step surfaces 53 are respectively provided at the positions corresponding to the limiting protrusions 62 in the fixed box 5; after the second elastic member 11 pushes the locking buckle 6 to extend out of the fixed box 5 to the limit position, the limiting protrusions 62 will respectively connect with the corresponding limiting step surfaces 53, and the extension travel of the locking buckle 6 is limited by the cooperation of the limiting protrusions 62 and the limiting step surfaces 53, thereby improving the stability of the transmission and enabling the locking buckle 6 to be limited in the fixed box 5.

[0042] In order to limit and guide the movement direction of the locking buckle 6, two second guide grooves 63 are provided on the locking buckle 6, and second guide blocks 54 are respectively provided at positions corresponding to the second guide grooves 63 on the fixed box 5, and the second guide blocks 54 extend into the second guide grooves 63 and are slidably connected with the second guide grooves 63. In the process of pressing the locking buckle 6 to retract the fixed box 5 or the second elastic member 11 pushing the locking buckle 6 to extend out of the fixed box 5, the second guide blocks 54 slide in the second guide grooves 63 respectively, and the extension or retraction direction of the locking buckle 6 can be limited and guided by the cooperation of the second guide blocks 54 and the second guide grooves 63, ensuring that the locking buckle 6 can clamp or detach from the three-proof mobile terminal, thereby improving the working stability of the support frame.

[0043] A rotatable damping gear 12 is installed on the fixed box 5, and a rack 13 is provided on the locking buckle 6, and the damping gear 12 is meshed and connected with the rack 13. When the second elastic member 11 pushes the locking buckle 6 out of the fixed box 5, the rack 13 will push the damping gear 12 to rotate; through the damping effect of the damping gear 12, the process of the locking buckle 6 extending out of the fixed box 5 is relatively slow, avoiding the situation where the locking buckle 6 bounces up quickly and hurts the user; the user's operating feel is improved, and thus the user's use experience can be improved. In the specific use process, after the user pushes the unlocking member 8 to disengage the sliding member 9 from the limit block 51, under the action of the second elastic member 11 and the damping gear 12, the locking buckle 6 will slowly rise from the fixed box 5, which improves the ornamental value and ensures the safety of the user.

[0044] The limiting mechanism includes a limiting groove 14 arranged on the base 1, and the limiting groove 14 can be used to accommodate the three-proof mobile terminal. The conductive member 3 is arranged in the limiting groove 14 and is electrically connected to the output connector 4 on the base 1; when using the support frame, the three-proof mobile terminal is placed in the limiting groove 14, and the locking buckle 6 can be operated to push the locking block 7 to abut against the end of the three-proof mobile terminal away from the limiting groove 14, and the three-proof mobile terminal is clamped by the locking block and the limiting groove 14, so that the three-proof mobile terminal is stably placed on the support frame.

[0045] In this embodiment, two positioning columns 15 are provided in the limiting groove 14, and the positioning columns 15 are used for plugging and positioning with the three-proof mobile terminal. The three-proof mobile terminal is provided with a positioning hole. In the process of placing the three-proof mobile terminal in the limiting groove 14, the three-proof mobile terminal can be fixed to the limiting groove 14 by aligning the positioning columns 15 with the positioning holes and inserting the positioning columns 15 into the corresponding positioning holes. By providing the positioning columns 15, the three-proof mobile terminal can be placed more firmly on the support frame, which improves the stability of the support frame and ensures that the three-proof mobile terminal can output a stable high-definition signal through the support frame.

[0046] Working principle:

[0047] In the initial state, the locking buckle 6 extends out of the fixing box 5, and the sliding block is separated from the limiting block 51. When using the support frame, the three-proof mobile terminal is placed in the limiting groove 14, and the positioning column 15 on the three-proof mobile terminal is aligned with the positioning column 15 in the limiting groove 14, and the positioning column 15 is inserted into the corresponding positioning hole; when the positioning column 15 is inserted into the positioning hole of the three-proof mobile terminal, the contact electrode on the three-proof mobile terminal is also in contact with the guide piece in the limiting groove 14, so that the three-proof mobile terminal is electrically connected to the base 1.

[0048] Afterwards, the user pushes the unlocking member 8 to extend one end of the locking buckle 6, so that it moves toward the direction close to the first elastic member 10, and presses the locking buckle 6 downward. The unlocking member 8 will push the sliding member 9 to move toward the first elastic member 10, thereby compressing the first elastic member 10; at the same time, the first inclined surface 92 will be connected with the second inclined surface 52 and slide on the second inclined surface 52; and as the locking buckle 6 moves downward, the first inclined surface 92 is separated from the second inclined surface 52, and the sliding member 9 will pass over the limit block 51; at this time, the user can release the unlocking member 8, and under the action of the elastic force of the first elastic member 10, the sliding member 9 and the unlocking member 8 will be pushed to move toward the limit block 51 until the sliding member 9 is fixedly engaged with the limit block 51, and at this time, the locking buckle 6 also drives the locking block 7 to abut against the end of the three-proof mobile terminal away from the limit mechanism, and the three-proof mobile terminal is clamped and fixed by the cooperation of the locking block 7 and the limit groove 14; so that the three-proof mobile terminal is stably electrically connected with the conductive member 3. At this time, an external device such as a projector can be connected through the output connector 4 on the base 1, so that the three-proof mobile terminal can achieve stable high-definition signal output through the base 1.

[0049] In the process of pressing the locking buckle 6 downward, the locking buckle 6 will compress the second elastic member 11; when it is necessary to take out the three-proof mobile terminal, the user pushes the unlocking member 8 to move it in the direction close to the first elastic member 10, and the unlocking member 8 will drive the sliding member 9 to move in the direction away from the limit block 51 until the sliding member 9 is separated from the limit block 51; at this time, the second elastic member 11 will release elastic potential energy, thereby pushing the locking buckle 6 out of the fixed box 5, until the locking buckle 6 drives the locking block 7 to be separated from the three-proof mobile terminal, and the user can take out the three-proof mobile terminal from the limit slot 14. In the process of the locking buckle 6 extending, the rack 13 will push the damping gear 12 to rotate, and through the damping effect of the damping gear 12, the process of the locking buckle 6 extending out of the fixed box 5 is relatively slow, so as to avoid the locking buckle 6 from bouncing up quickly and causing harm to the user.

The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
