Description

Technical Field

[0001] This utility model relates to the field of installation structures, specifically a multi-mode installation structure and a smart terminal system. Background Technology

[0002] With the rapid development of the smart home industry, users' needs for smart terminals have expanded from simple wall-mounted installations to diverse scenarios such as desktop placement and handheld mobility, in order to adapt to different spatial layouts and operational convenience requirements.

[0003] Currently, the most common connection methods between electronic products and mounting brackets are screwing or magnetic attachment. However, screwing is very inconvenient and makes it difficult to quickly switch installation positions. Magnetic attachment alone cannot ensure installation stability and poses a risk of the smart terminal falling off due to inaccurate connection. It is evident that most existing smart terminals can only meet one fixed scenario of wall mounting or desktop use, lacking flexible switching capabilities. For the few products that can accommodate both wall and desktop usage modes, the operation process when switching scenarios is cumbersome, affecting the user experience.

[0004] The research objective of this utility model is to design a multi-mode installation structure and a smart terminal system to address the problems existing in the above-mentioned prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a multi-mode installation structure and a smart terminal system, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A multi-mode installation structure and intelligent terminal system, comprising:

The docking structure and positioning structure also include a first magnet and a second magnet respectively disposed in the first device and the second device and corresponding to the first magnetic attraction part and the second magnetic attraction part. The first magnetic attraction part is fitted into the positioning protrusion and magnetically docks with the second magnetic attraction part. The locking member is slidably disposed up and down and includes two locking hooks that respectively move through the lower and upper sides of the docking groove. The two locking hooks are folded upward. The upper lower side and the lower lower side of the positioning protrusion are respectively recessed upward to form two hook grooves. The outer end of the positioning protrusion is rounded. The ends of the two locking hooks are inclined to form a pressing surface corresponding to the arc shape of the upper lower side and the lower lower side of the positioning protrusion.

[0011] Furthermore, the first magnetic suction part is circumferentially recessed and provided with a plurality of precision grooves that communicate with the docking groove, and the second magnetic suction part is circumferentially protruding and provided with a plurality of precision protrusions that connect with the positioning protrusion, and the plurality of precision protrusions respectively correspond to and are adapted to the plurality of precision grooves.

[0012] Furthermore, the locking member extends vertically and is provided with a plurality of vertically spaced and extended elongated holes. The lower end of the locking member protrudes downward and is provided with a plurality of guide posts, and the upper end expands outward and abuts against the inner wall of the first device to form an abutment portion. The upper end of the abutment portion slides through the upper wall of the first device and is connected to the driving member used to press and drive the locking member to slide up and down. The docking structure also includes a sliding area and a limiting area recessed in the first device for the locking member and the plurality of guide posts to slide up and down respectively. The sliding area is provided with a plurality of limiting posts corresponding to the plurality of elongated holes respectively. The reset elastic member is a plurality of springs and is respectively sleeved on the outside of the plurality of guide posts and abuts against the limiting area and the locking member.

[0013] Furthermore, the locking member is provided with a power connection hole corresponding to the middle of the first magnetic attraction part. The docking structure also includes a first power connection base disposed in the first device and passing through the power connection hole and the first magnetic attraction part.

After the first magnetic attraction part and the second magnetic attraction part are magnetically docked, the first power connection base and the second power connection base are connected and energized.

[0014] Furthermore, the first device is a smart terminal and the second device is a mounting base and a support base, or the first device is a mounting base and a support base and the second device is a smart terminal; the smart terminal is equipped with a battery, and the mounting base and the support base are respectively used to connect to an external power source.

[0015] Furthermore, one side of the mounting base is used for screwing and mounting to the wall, the support base is used for placing on the table and has a counterweight inside, the top of the support base is inclined to form the mounting side, the docking structure is located at the rear of the smart terminal, and there are two positioning structures, which are respectively located on the other side of the mounting base and the mounting side of the support base.

[0016] A smart terminal system includes a smart terminal, a mounting base, and a support base. The smart terminal is mounted on the mounting base or support base using a multi-mode installation structure as described above.

[0017] Therefore, the beneficial effects of this utility model are:

[0018] 1. The installation and connection between the first and second devices are facilitated through the design of the docking and positioning structures. First, magnetic docking is achieved through the first and second magnetic suction parts, thereby improving the ease of installation and connection. Second, installation positioning is achieved through the insertion of the positioning protrusion and the docking groove, thus avoiding the situation where the magnetic docking offset leads to a decrease in adsorption capacity and the first and second devices easily detach from each other due to accidental contact. Furthermore, a locking component is added, allowing the locking hook to be displaced and reset, and then positioned within the hook groove. Thus, the hooking between the locking hook and the hook groove prevents the positioning protrusion and the docking groove from detaching, and the first magnetic suction part and the second magnetic suction part... The two magnetic suction parts disengage, improving the stability of the positioning protrusion inserted into the docking groove and enhancing the stability of the mutual magnetic attraction between the first and second magnetic suction parts. This improves the stability of the installation connection between the first and second devices while ensuring convenient installation. When the first device is a smart terminal and the second device is a mounting base in different locations, such as a wall mount or a desktop stand, the smart terminal can be easily and quickly switched to different mounting bases for convenient installation and disassembly in multiple modes, enabling multi-mode usage scenarios to meet different user needs.

[0019] 2. By making the docking groove and positioning protrusion annular, the contact area between the two is increased, improving the stability of the insertion. The first magnetic suction part is fitted into the positioning protrusion and magnetically connected to the second magnetic suction part, realizing the fitting, positioning and mutual support between the first and second magnetic suction parts, ensuring magnetic stability. On this basis, two locking hooks and hook grooves are added and distributed vertically to improve the limiting effect of the locking hooks and hook grooves, further preventing the first and second devices from separating after accidental contact, further improving the stability of the installation connection. Furthermore, through the rounded corners of the outer end of the positioning protrusion and the inclined pressing surface of the locking hook end, during the magnetic insertion of the first and second magnetic suction parts, the locking member can be moved down to the locking hook extending into the hook groove opening by pressing down the outer end of the positioning protrusion. Then, the locking member is driven up and reset by the reset elastic member until the locking hook is hooked into the hook groove, improving the smoothness of the locking hook being hooked into the hook groove.

[0020] 3. During the magnetic attraction docking process of the first magnetic attraction part and the second magnetic attraction part, the initial positioning is first achieved through the docking groove and the positioning protrusion, and then the precise positioning is achieved through the precise positioning and insertion of several precision grooves and precision protrusions. This solves the problem of blind assembly and alignment between the first magnetic attraction part and the second magnetic attraction part, and achieves precise magnetic attraction docking. In turn, the magnetic attraction force can ensure the stability of the connection between the first device and the second device.

[0021] 4. Through the cooperation between several elongated holes and limiting posts, as well as the setting of sliding area and limiting area, the up and down sliding of the locking part is guided and limited, and the extension and retraction of the reset elastic part is also guided and limited. Through the cooperation between the abutment part and the reset elastic part, the locking part is controlled to stably reset after being compressed, thereby improving the stability of the up and down sliding of the locking part, and thus improving the stability of disassembly and assembly between the docking structure and the positioning structure.

[0022] 5. The power connection hole allows the first power connection base to be installed stably without being affected by the sliding of the locking parts. This ensures that after the docking structure and the positioning structure are docked, the first power connection base and the second power connection base can be stably connected. This allows the first device to be a smart terminal and to be installed on the mounting base or support base through the installation structure. The battery inside the smart terminal can be charged through this stable power connection, improving the charging convenience of the smart terminal. Attached Figure Description

[0033] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0034] refer to Figure 1-10 A multi-mode installation structure and intelligent terminal system, comprising:

[0035] The docking structure 1 includes a docking groove 11 recessed in the outer wall of the corresponding first device, a locking member 12 movably disposed in the first device and connected to a reset elastic member 13, a first magnetic suction part 14 disposed in the outer wall of the first device and used for magnetic attraction, and a driving member 19 disposed on the outside of the first device and used to drive the locking member 12 to move. The locking member 12 includes a locking hook 121 that movably passes through one side of the docking groove 11 and is folded towards the other side.

[0036] The positioning structure 2 includes a positioning protrusion 21 protruding from the outer wall of the corresponding second device and corresponding to the docking groove 11, and a second magnetic suction part 22 located on the outer wall of the second device for magnetic attraction. One side of the positioning protrusion 21 is recessed to form a hook groove 211 corresponding to the locking hook 121. After the positioning protrusion 21 is inserted into the docking groove 11 and the first magnetic suction part 14 and the second magnetic suction part 22 are magnetically attracted and connected, the locking hook 121 is displaced by pressure and embedded in the hook groove 211. After being reset by the elastic force of the reset elastic member 13, the locking hook 121 is located in the hook groove 211. When disassembly is required, the locking hook 121 is moved by the driving part until the locking hook 121 can be disengaged from the hook groove 211, thereby separating the docking structure 1 and the positioning structure 2 to separate the first device and the second device.

[0037] Specifically, the first device is a smart terminal 3, and the second device is a mounting base 4 and a support base 5, or the first device is a mounting base 4 and a support base 5, and the second device is a smart terminal 3; the smart terminal 3 is equipped with a battery, and the mounting base 4 and the support base 5 are respectively used to connect to an external power source. Preferably, in this embodiment, the first device is a smart terminal 3, and the second device is a mounting base 4 and a support base 5.

[0038] The above structure facilitates the installation and connection between the first and second devices through the docking structure 1 and the positioning structure 2. First, magnetic docking is achieved through the first magnetic suction part 14 and the second magnetic suction part 22, thereby improving the ease of installation and connection. Second, the installation positioning is achieved through the insertion of the positioning protrusion 21 and the docking groove 11, thereby avoiding the situation where the magnetic docking offset leads to a decrease in adsorption capacity and the first and second devices easily detach from each other due to accidental contact. On this basis, a locking member 12 is added so that after the locking hook 121 can be displaced and reset, the locking hook 121 is located in the hook groove 211. Thus, the hooking between the locking hook 121 and the hook groove 211 can prevent the positioning protrusion 21 from detaching from the docking groove 11. The first magnetic suction part 14 and the second magnetic suction part 22 are disengaged, which improves the stability of the positioning protrusion 21 inserted into the docking groove 11 and improves the stability of the mutual magnetic attraction between the first magnetic suction part 14 and the second magnetic suction part 22. Thus, while achieving convenient installation and connection between the first device and the second device, the stability of the installation and connection between the two is improved. When the first device is a smart terminal 3 and the second device is a mounting base set in different positions, such as a wall mount 4 or a desktop support 5, the smart terminal 3 can be easily and quickly switched to different mounting bases for convenient installation and disassembly in multiple modes, realizing multiple usage scenarios to meet the different usage needs of users.

[0039] To improve installation and connection stability, the docking groove 11 is annular and surrounds the outer periphery of the first magnetic attraction part 14, and the positioning protrusion 21 is annular and surrounds the outer periphery of the second magnetic attraction part 22. The docking structure 1 and the positioning structure 2 also include a first magnet 141 and a second magnet 221 respectively disposed in the first device and the second device and corresponding to the first magnetic attraction part 14 and the second magnetic attraction part 22. Specifically, four first magnets 141 and four second magnets 221 are respectively provided in the first device and the second device and are respectively disposed inside the first magnetic attraction part 14 and the second magnetic attraction part 22. A magnetic suction part 14 is fitted into the positioning protrusion 21 and magnetically connected to the second magnetic suction part 22. The locking member 12 is slidably arranged up and down and includes two locking hooks 121 that respectively move through the lower and upper sides of the docking groove 11. The two locking hooks 121 are folded upward. The upper lower side and the lower lower side of the positioning protrusion 21 are respectively recessed upward to form two hook grooves 211. The outer end of the positioning protrusion 21 is rounded. The ends of the two locking hooks 121 are inclined to form a pressing surface 1211 corresponding to the arc shape of the upper lower side and the lower lower side of the positioning protrusion 21. The above structure increases the contact area and stability of the insertion by making the docking groove 11 and the positioning protrusion 21 annular. It also allows the first magnetic suction part 14 to fit into the positioning protrusion 21 and magnetically engage with the second magnetic suction part 22, achieving proper positioning and mutual support between the first magnetic suction part 14 and the second magnetic suction part 22, ensuring magnetic stability. Furthermore, two locking hooks 121 and two hook grooves 211 are added, one above the other, to improve their limiting effect and further prevent the first and second devices from being misaligned. The occurrence of phase separation after collision further improves the stability of the installation connection. Furthermore, through the rounded corners of the outer end of the positioning protrusion 21 and the inclined buckling surface 1211 at the end of the locking hook 121, during the engagement and magnetic attraction of the first magnetic attraction part 14 and the second magnetic attraction part 22, the outer end of the positioning protrusion 21 can press down the buckling surface 1211 to move the locking member 12 down until the locking hook 121 extends into the groove of the hook groove 211. Then, the reset elastic member 13 drives the locking member 12 to move up and reset to the locking hook 121 hooked into the hook groove 211, improving the smoothness of the locking hook 121 hooking into the hook groove 211.

[0040] To improve the accuracy of the docking installation of the docking structure 1 and the positioning structure 2, the first magnetic suction part 14 is circumferentially recessed with a plurality of precision grooves 15 that connect to the docking groove 11, and the second magnetic suction part 22 is circumferentially protruding with a plurality of precision protrusions 23 that connect to the positioning protrusions 21. Each of the precision protrusions 23 corresponds to and is fitted with a plurality of precision grooves 15. Thus, during the magnetic docking process of the first magnetic suction part 14 and the second magnetic suction part 22, preliminary positioning is first achieved through the docking grooves 11 and the positioning protrusions 21, and then precise positioning is achieved through the precise positioning and insertion of the plurality of precision grooves 15 and precision protrusions 23. This solves the problem of blind assembly and alignment between the first magnetic suction part 14 and the second magnetic suction part 22, achieving precise magnetic docking. Furthermore, the magnetic force ensures the stability of the connection between the first and second devices.

[0041] To improve the stability of the locking member 12 sliding up and down, the locking member 12 extends vertically and is provided with a plurality of vertically spaced and extended elongated holes 122. The lower end of the locking member 12 protrudes downward and is provided with a plurality of guide posts 123, and the upper end expands outward and abuts against the inner wall of the first device to form an abutment part 124. The upper end of the abutment part 124 slides through the upper wall of the first device and is connected to the driving member 19 for pressing and driving the locking member 12 to slide up and down. Specifically, the driving member 19 is a button exposed on the outside of the first device. The docking structure 1 also includes a sliding area 16 and a limiting area 17 recessed in the first device and respectively allowing the locking member 12 and the plurality of guide posts 123 to slide up and down. The sliding area 16 is provided with a plurality of limiting posts 161 corresponding to the plurality of elongated holes 122. The reset elastic member 13 is a plurality of springs and is respectively sleeved on the outside of the plurality of guide posts 123 and abuts against the limiting area 17 and the locking member 12. The above structure guides and limits the up-and-down sliding of the locking member 12 through the cooperation between several elongated holes 122 and the limiting post 161, as well as the setting of the sliding area 16 and the limiting area 17. It also guides and limits the extension and retraction of the reset elastic member 13. Through the cooperation between the abutment part 124 and the reset elastic member 13, it controls the locking member 12 to stably reset after being compressed, thereby improving the stability of the up-and-down sliding of the locking member 12 and thus improving the stability of the disassembly and assembly between the docking structure 1 and the positioning structure 2.

[0042] To achieve stable power connection between the first device and the second device, the locking member 12 is provided with a power connection hole 125 corresponding to the middle of the first magnetic suction part 14. The docking structure 1 also includes a first power connection socket 18 disposed in the first device and passing through the power connection hole 125 and the first magnetic suction part 14. The positioning structure 2 also includes a second power connection socket 24 disposed in the second device and with its power connection end passing through the second magnetic suction part 22. The first device or the second device is used to connect to an external power source. After the first magnetic suction part 14 and the second magnetic suction part 22 are magnetically docked, the first power connection socket 18 and the second power connection socket 24 are connected and energized. Specifically, the second power connection socket 24 is a male power connection socket with a plurality of pogo pins (spring pins) at its power connection end, and the first power connection socket 18 is a female power connection socket. The above structure, through the setting of the power connection hole 125, allows the first power connection base 18 to be stably installed without being affected by the up-and-down sliding of the locking member 12. This ensures that after the docking structure 1 and the positioning structure 2 are docked, the first power connection base 18 and the second power connection base 24 can be stably connected. This allows the first device to be a smart terminal 3, which is installed and connected to the mounting base 4 or the support base 5 through the installation structure. The battery inside the smart terminal 3 can be charged through this stable power connection, improving the charging convenience of the smart terminal 3.

[0043] To improve the stability of the mounting base 4 and the support base 5, one side of the mounting base 4 is screwed to the wall, thereby improving the stability of the mounting base 4. The support base 5 is placed on the table and has a counterweight inside. The top of the support base 5 is inclined to form an installation side 51. The docking structure 1 is located at the rear of the smart terminal 3. The counterweight increases the weight of the support base 5 and lowers the center of gravity of the support base 5, preventing the support base 5 from tipping over due to excessive pressure on one side after the smart terminal 3 is installed. The inclined installation side 51 ensures that the screen angle of the smart terminal 3 is suitable for user viewing and use after installation, improving the user experience. There are two positioning structures 2, one on the other side of the mounting base 4 and the other on the installation side 51 of the support base 5.

[0044] It also includes a smart terminal system, comprising a smart terminal 3, a mounting base 4, and a support base 5. The smart terminal 3 is installed on the mounting base 4 or the support base 5 using a multi-mode installation structure as described above. This allows the smart terminal 3 to be easily and quickly switched between different mounting locations, enabling convenient installation and removal in multiple modes, and facilitating various usage scenarios to meet different user needs.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
