Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical device accessories, and particularly to a self-balancing flipping mechanism. Background Art
[0002] In some medical devices, a back plate is required to fix a tablet computer or a flat panel display, and in some cases, a rotatable and retractable tray is also provided on the back plate. When not in use, the tray is locked on the back plate by a latch assembly. When in use, the tray is opened downward to a horizontal state to place a keyboard, a mouse, tools, etc.
[0003] The existing tray is simply hinged to the back plate by a hinge. When the tray is opened, it is easy to quickly drop, which will not only generate vibration and noise, but also the keyboard on the tray is likely to fly out of the tray and fall to the ground, causing damage. When closing the tray, the user needs to apply a relatively large operating force to overcome the gravity of the tray and the keyboard. This not only increases the operating difficulty of the user, but also easily leads to unstable operation and affects the use experience. Utility Model Content
[0004] In order to solve the technical problems that the existing tray is easy to quickly drop when opened, generating vibration and noise, and requires a relatively large operating force from the user when closed, affecting the use experience, the present utility model provides a self-balancing flipping mechanism.
[0005] The technical solution provided by this application is as follows: A self-balancing flipping mechanism includes a back plate, a tray, and a latch assembly. The tray is hinged to the back plate, and the latch assembly is used to lock the tray on the back plate when the tray is closed. It further includes a torsion spring hinge and a one-way buffer hinge. The tray is hinged to the back plate through the torsion spring hinge and the one-way buffer hinge. The torsion spring hinge is used to support and upwardly balance the rotational torque generated by the gravity of the tray, and the one-way buffer hinge is used to buffer the downward rotational torque generated when the tray is opened.
[0006] By adopting the above technical solutions, the self-balancing flipping mechanism of the present application is provided with a torsion spring hinge and a one-way buffer hinge at the same time. When opening the tray, the torsion of the torsion spring hinge is in the minimum state at the beginning, and as the opening degree of the tray increases, the torsion gradually increases. However, the torsion is always less than the rotational torsion generated by the gravity of the tray. Therefore, during the entire opening process of the tray, without external force, the opening speed becomes faster and faster. For this reason, the present application adds a one-way buffer hinge to provide buffer resistance, prevent the tray from falling rapidly, and reduce the generation of vibration and noise; when closing the tray, the one-way buffer hinge does not have a buffering effect and does not provide rotational resistance. The torsion of the torsion spring hinge is in the maximum state at the beginning, and as the opening degree of the tray decreases, the torsion gradually decreases. Correspondingly, the rotational torsion generated by the gravity of the tray also gradually decreases. As long as the torsion parameters of the torsion spring hinge are adjusted properly, most of the rotational torsion generated by the gravity of the tray can be balanced, and the tray can be pushed to close with a very small force, which is very labor-saving, reduces the operation difficulty, and improves the user experience.
[0007] Optionally, a buffer member is further installed on the back plate, and the buffer member is arranged below the lock assembly and is used to play a buffering role when the tray is closed.
[0008] By adopting the above technical solutions, the buffer member of the present application can be made of an elastic material or an elastic structure. When closing the tray, the buffer member plays a buffering role on the tray to avoid hard impacts when the user closes the tray forcefully.
[0009] Optionally, the buffer member includes a mounting seat, a buffer head and a spring. The buffer head and the spring are both arranged in the mounting seat. The spring enables the buffer head to axially expand and contract, and the buffer head is used to push the tray open by a certain angle when the tray is opened.
[0010] By adopting the above technical solutions, the buffer member of the present application realizes the buffering effect through the elastic expansion and contraction function of the buffer head. When closing the tray, the buffer head is compressed, and then the tray is locked by the lock assembly. When opening the tray, the buffer head pops outwards, which can make the tray bounce open by a certain angle, increase the operating space for the user's hand, and reduce the manual operation difficulty.
[0011] Optionally, a limit support seat is further installed on the back plate. The limit support seat is located below the tray and is used to support and limit the extreme limit of the tray rotating downwards.
[0012] By adopting the above technical solutions, when the tray of the present application is in the use state, it is generally in a horizontal state. The limit support seat plays a supporting and limiting role. In addition, if the user presses the tray too hard, the connection parts of the torsion spring hinge and the one-way buffer hinge with the back plate are subjected to greater forces and are prone to structural damage. For this reason, the present application adds a limit support seat to provide more support points for the tray and improve the maximum load-bearing weight and impact force of the tray.
[0013] Optionally, the number of the buffer members and the limit support seats is two each. The two buffer members are arranged horizontally in parallel, and the two limit support seats are also arranged horizontally in parallel.
[0014] By adopting the above technical solution, the two buffer members of the present application are arranged horizontally in parallel, so that the force is more balanced and the buffering effect is better; the two limit support seats are arranged horizontally in parallel, and the support for the tray is also more balanced, preventing the tray from tilting when pressed.
[0015] Optionally, the latch assembly includes a push-type bolt and a latch. The push-type bolt is arranged on the back plate, the latch is arranged on the outer edge of the tray, a buckle groove is provided on the latch, and the push-type bolt is inserted into the buckle groove to lock the tray.
[0016] By adopting the above technical solution, the latch assembly of the present application can be locked by closing the tray with force, and can be unlocked by pressing, with simple operation and convenient use.
[0017] Optionally, fixing holes are provided on the back plate for fixing a tablet computer or a display.
[0018] By adopting the above technical solution, a tablet computer or a display can be fixed on the fixing holes of the back plate of the present application, which is convenient for medical staff to check the condition data.
[0019] Optionally, a groove is provided on the tray for placing a keyboard.
[0020] By adopting the above technical solution, the groove on the tray of the present application can place a keyboard, which is convenient for medical staff to input medical data and perform related operations.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. When the self-balancing flipping mechanism of the present application opens the tray, it can prevent the tray from falling rapidly, reducing the generation of vibration and noise; when closing the tray, a very small force can be used to push the tray to close, which is very labor-saving, reducing the operation difficulty and improving the user experience;
[0023] 2. The buffer member of the present application includes a buffer head and a spring. When opening the tray, the buffer head pops outwards, which can make the tray bounce open at a certain angle, increasing the operation space for the user's hand and reducing the manual operation difficulty;
[0024] 3. The present application is additionally provided with limit support seats, providing more support points for the tray and improving the maximum load-bearing weight and impact force of the tray. Brief Description of the Drawings

Detailed implementation manners
[0031] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.
[0032] Referring to Figure 1 , the embodiments of the present application disclose a self - balancing flipping mechanism including a back plate 1, a support plate 2 and a locking component 3. The back plate 1 is provided with fixing holes 11 for fixing a tablet computer or a display. The support plate 2 is hinged to the back plate 1. The support plate 2 is provided with a groove 21 for placing a keyboard. The locking component 3 is used to lock the support plate 2 on the back plate 1 when the support plate 2 is closed. The self - balancing flipping mechanism further includes a torsion spring hinge 4 and a one - way buffer hinge 5. The support plate 2 is hinged to the back plate 1 through the torsion spring hinge 4 and the one - way buffer hinge 5. The torsion spring hinge 4 is used to support and balance upward the rotational torque generated by the gravity of the support plate 2, and the one - way buffer hinge 5 is used to buffer the downward rotational torque generated when the support plate 2 is opened.
[0033] Referring to Figure 1 , Figure 4 and Figure 5, a buffer member 6 is further installed on the back plate 1. The number of the buffer members 6 is two, and the two buffer members 6 are arranged horizontally in parallel. The buffer member 6 is arranged below the lock assembly 3 and is used to play a buffering role when the tray 2 is closed. The buffer member 6 can be made of an elastic material or an elastic structure, and the buffering effect is achieved through the elastic telescopic function of the buffer head 62. In this embodiment, the buffer member 6 includes a mounting seat 61, a buffer head 62 and a spring 63. The buffer head 62 and the spring 63 are both arranged in the mounting seat 61. The spring 63 enables the buffer head 62 to axially expand and contract. The buffer head 62 is used to push the tray 2 open at a certain angle when the tray 2 is opened. When the tray 2 is closed, the buffer head 62 is compressed, and then the tray 2 is locked by the lock assembly 3. When the tray 2 is opened, the buffer head 62 ejects outwards, which can make the tray 2 bounce open at a certain angle, increasing the operating space for the user's hand and reducing the manual operation difficulty.
[0034] Refer to Figure 2 and Figure 3 , a limit support seat 7 is further installed on the back plate 1. The number of the limit support seats 7 is two, and the two limit support seats 7 are also arranged horizontally in parallel. The limit support seat 7 is located below the tray 2 and is used to support and limit the extreme position of the downward rotation of the tray 2. When the tray 2 is in use, it is generally in a horizontal state, and the limit support seat 7 plays a role in supporting and limiting. In addition, if the user presses the tray 2 too hard, the connection parts of the torsion spring hinge 4 and the one-way buffer hinge 5 with the back plate 1 are subjected to greater force and are easily damaged. The two horizontally arranged limit support seats 7 prevent the tray 2 from tilting under pressure and also provide more support points for the tray 2, improving the maximum load-bearing weight and impact force of the tray 2.
[0035] Refer to Figure 2 , the lock assembly 3 includes a push-button bolt 31 and a lock 32. The push-button bolt 31 is arranged on the back plate 1, and the lock 32 is arranged on the outer edge of the tray 2. A buckle groove is provided on the lock 32, and the push-button bolt 31 is inserted into the buckle groove to lock the tray 2. Closing the tray 2 forcefully can lock the lock assembly 3, and unlocking the lock assembly 3 can be achieved by pressing, with simple operation and convenient use.
[0036] The implementation principle of the self-balancing flipping mechanism described in this application is as follows: The self-balancing flipping mechanism of this application is provided with a torsion spring hinge 4 and a one-way buffer hinge 5 at the same time. When opening the tray 2, the torsion force of the torsion spring hinge 4 is in the minimum state at the beginning, and as the opening degree of the tray 2 increases, the torsion force gradually increases. However, the torsion force is always less than the rotational torsion force generated by the gravity of the tray 2. Therefore, during the entire opening process of the tray 2, without external force, the opening speed becomes faster and faster. For this reason, this application adds a one-way buffer hinge 5 to provide buffer resistance to prevent the tray 2 from falling rapidly, reducing the generation of vibration and noise; when closing the tray 2, the one-way buffer hinge 5 does not have a buffering effect and does not provide rotational resistance. The torsion force of the torsion spring hinge 4 is in the maximum state at the beginning, and as the opening degree of the tray 2 decreases, the torsion force gradually decreases. Correspondingly, the rotational torsion force generated by the gravity of the tray 2 also gradually decreases. As long as the torsion force parameters of the torsion spring hinge 4 are adjusted properly, most of the rotational torsion force generated by the gravity of the tray 2 can be balanced, and the tray 2 can be pushed to close with a very small force, which is very labor-saving, reduces the operation difficulty, and improves the user experience.
[0037] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
