Description

Technical Field

[0001] The utility model relates to a semi-hidden door opening mechanism. Background Art

[0002] With the development of society, people have more and more demands for automated products. The connecting rod driver can be applied to various fields such as automobiles and homes, enabling related products to achieve the function of automatic door opening. For some existing drivers, the internal part structure is difficult to withstand large torques. When the torque is large, the internal lead screw and limit rod are prone to bending and damage, and the service life is short, making it difficult to be applicable to the opening and closing of doors.

[0003] In addition, when designing a fully hidden drive mechanism on a door, under normal circumstances, the connecting rod pushes the door leaf close to the fully open state. To achieve the rotation of the door leaf, a very large force is required, and the fully hidden solution is almost impossible to achieve. Summary of the Utility Model

[0004] The utility model provides a semi-hidden door opening mechanism, which can achieve the purpose of hiding without affecting the opening and closing of the door.

[0005] The technical solution for solving the above technical problems is as follows:

[0006] A semi-hidden door opening mechanism includes a drive mechanism for being installed on a door frame, and further includes:

[0007] A bracket for being hinged to a door leaf, the bracket is connected to the power output end of the drive mechanism, and a coupling groove is provided on the bracket;

[0008] A pin shaft for being fixed to the door leaf, and the coupling groove is combined with or separated from the pin shaft during the rotation of the bracket driven by the drive mechanism;

[0009] A triggering component for being installed on the door frame;

[0010] A blocking mechanism for blocking the pin shaft entering the coupling groove;

[0011] A self-locking mechanism, the self-locking mechanism is installed on the bracket, the self-locking mechanism is triggered by the triggering component and acts to form self-locking during the rotation of the bracket, and the blocking mechanism is connected to the self-locking mechanism.

[0012] In the semi-hidden door opening mechanism of the utility model, during the opening process of the door leaf, the bracket can rotate out of the door leaf to a fixed position and drive the door leaf to open. During the closing process of the door leaf, the bracket first drives the door leaf to close, and then as the drive mechanism continues to push, the bracket rotates around its own rotation center until it is completely hidden inside the door leaf. During the opening or closing process of the door leaf, relying on the self-locking mechanism installed on the bracket, self-locking is achieved by one trigger, and unlocking is achieved by another trigger.

[0013] The structure of the present utility model can hide the driving mechanism inside the door frame and the bracket inside the door leaf, and when achieving the hiding, it does not affect the opening and closing of the door. Description of the Drawings

Detailed Description of the Invention

[0023] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0026] In the present utility model, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "connected to", "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0028] As Figures 1 to 6 shown, a semi-hidden door opening mechanism of the present utility model includes a driving mechanism 1 for mounting on a door frame (the door frame is not shown in the figure), a bracket 2 for hinging with a door leaf A, a pin shaft 3 for fixing with the door leaf A, a triggering component 4 for mounting on the door frame, a blocking mechanism, and a self-locking mechanism. The driving mechanism 1 can adopt a cylinder or a hydraulic cylinder. A groove is provided on the door frame, and the driving mechanism 1 is located in the groove and fixed to the door frame.

[0029] The bracket 2 is connected to the power output end of the driving mechanism 1, and a first pin 2c is provided on the bracket 2. The first pin 2c is hinged to the power output end of the driving mechanism 1, and a coupling groove 2a is provided on the bracket 2; the coupling groove 2a is arc-shaped, and a second pin A1 is installed on the top of the door leaf A. The bracket 2 is hinged to the second pin A1. When the driving mechanism 1 outputs power, the bracket 2 is driven to rotate with the axis of the second pin A1 as the rotation center. A mounting groove is provided on the top of the door leaf A, and the bracket 2 is located in the mounting groove.

[0030] The pin shaft 3 is fixed on the top of the door leaf A, and the bracket 2 makes the coupling groove 2a engage or disengage with the pin shaft 3 during the rotation process driven by the driving mechanism 1. For example, the driving mechanism 1 drives the bracket 2 to rotate counterclockwise relative to the door leaf A with the axis of the second pin shaft A1 as the rotation center, that is, the door leaf A does not move, and the bracket 2 rotates counterclockwise relative to the door leaf. When the bottom of the coupling groove 2a hits the pin shaft 3, if the driving mechanism 1 continues to output power at this time, the bracket 2 cannot continue to rotate counterclockwise. Under the action of the driving mechanism 1, the bracket 2 can only drive the door leaf A to rotate counterclockwise.

[0031] The trigger component 4 is fixed on the door frame, and the trigger component 4 is an axis. When the bracket 2 rotates counterclockwise under the drive of the driving mechanism 1, the self-locking mechanism installed on the bracket 2 abuts against the trigger component 4, so that the trigger component 4 triggers the self-locking mechanism to activate it.

[0032] The blocking mechanism blocks the pin shaft 3 entering the coupling groove 2a, and the blocking mechanism includes a column 5 and a blocking rod 6. One end of the column 5 is fixed to the self-locking mechanism, one end of the blocking rod 6 is fixed to the column 5, and the other end of the blocking rod 6 is a free end. The other end of the blocking rod 6 is located outside the coupling groove 2a. When the pin shaft 3 enters the coupling groove 2a, the bracket 2 drives the door leaf A to rotate counterclockwise. The self-locking mechanism is triggered by the trigger component 4 to produce displacement, and the column 5 follows the displacement of the self-locking mechanism, so that the other end of the blocking rod 6 corresponds to the inside of the coupling groove 2a, and then the blocking rod 6 blocks the pin shaft 3 located in the coupling groove 2a, so that the opening of the door leaf A is in a locked state.

[0033] The self-locking mechanism is installed on the bracket 2. When the bracket 2 is rotated, the self-locking mechanism is triggered by the trigger component 4 and is activated to form a self-locking state. The blocking mechanism is connected to the self-locking mechanism. The bracket 2 is provided with a clearance opening 2b. The bracket 2 has an inner cavity. The self-locking mechanism is located inside the inner cavity of the bracket 2. The blocking mechanism passes through the clearance opening 2b and is connected to the self-locking mechanism.

[0034] The self-locking mechanism includes a housing 9, a push rod 10, a support plate 11, a second spring 12, a locking hook 13, a locking buckle 14, and a torsion spring (the torsion spring is not shown in the figure). The housing 9 is located in the inner cavity of the bracket 2 and is fixed to the bracket 2. The upright column 5 passes through the relief opening 2b and is fixed to the push rod 10. One end of the push rod 10 extends into the housing 9 and is connected to the support plate 11 located inside the housing 9. The bracket 2 is provided with a guide hole, and the push rod 10 is in clearance fit with the guide hole. The relief opening 2b penetrates through to the guide hole. One end of the second spring 12 is connected to the support plate 1, and the other end of one end of the second spring 12 is connected to the housing 9. One end of the locking hook 13 is rotatably fitted with the support plate 11 and then connected to the torsion spring. A part of the locking hook 13 is L-shaped, and the end with the L-shaped part is rotatably fitted with the support plate 11 and then connected to the torsion spring. The torsion spring is connected to the support plate 11. When the locking hook 13 is subjected to a lateral squeezing force, the locking hook 13 swings. When the locking hook is not subjected to a lateral squeezing force, the torsion spring causes the locking hook 13 to reset, so as to maintain the positional accuracy of the locking hook 13.

[0035] The locking buckle 14 is located in the housing 9 and is connected to the housing 9. The housing 9 is also provided with an unlocking buckle 15 for unlocking. The unlocking buckle 15 corresponds to the locking buckle 14. The cross-sectional contour of the locking buckle 14 is quadrilateral, and the cross-sectional contour of the unlocking buckle 15 is triangular. The end face of the locking buckle 14 corresponding to the unlocking buckle 15 has a recess 14a. When the locking hook 13 hooks the recess 14a, the locking hook 13 and the locking buckle 14 are engaged, so that the self-locking mechanism is in a locked state.

[0036] The working process of this embodiment is as follows:

[0037] When it is necessary to switch from the closed door state to the open door state, the driving mechanism 1 drives the bracket 2 to rotate counterclockwise relative to the door leaf A with the axis line of the second pin shaft A1 as the rotation center, that is, the door leaf A does not move, and the bracket 2 rotates counterclockwise relative to the door leaf. When the bottom of the engaging groove 2a abuts against the pin shaft 3, at this time, the push rod 10 is in preliminary contact with the triggering component 4.

[0038] As the driving mechanism 1 continues to output power, since the bracket 2 is in cooperation with both the second pin shaft A1 and the pin shaft 3, the bracket 2 cannot rotate counterclockwise relative to the door leaf A alone, but can only drive the door leaf A to rotate counterclockwise together with the bracket 2.

[0039] During the rotation process of the bracket 2, the initial contact between the ejector rod 10 and the trigger member 4 evolves into the extrusion of the trigger member 4 on the ejector rod 10, thereby causing the ejector rod 10 to displace. The ejector rod 10 pushes the support plate 11 to displace and compress the second spring 12. During this process, the locking hook 13 displaces with the support plate 11, and the hook portion of the locking hook 13 swings under the extrusion of the buckle 14 during displacement. When the hook portion of the locking hook 13 passes over the buckle 14, the ejector rod 10 separates from the trigger member 4. Under the tension of the second spring 12, the hook portion of the locking hook 13 cooperates with the recess 14a, and the locking hook 13 is latched with the buckle 14, and the ejector rod 10 cannot displace. During the displacement process of the ejector rod 10 described above, the blocking mechanism displaces with the ejector rod 10, so that the free end of the blocking rod 6 gradually extends to the inside of the engaging groove 2a, and further the blocking rod 6 forms a block on the pin shaft 3 to prevent the opened door leaf A from resetting without operation.

[0040] When it is necessary to switch from the open door state to the closed door state, the driving mechanism 1 outputs power to make the bracket 2 rotate counterclockwise with the axis line of the second pin shaft A1 as the rotation center. Since the door leaf A and the bracket 2 are an integral body at this time, the door leaf A, the self-locking mechanism and the blocking mechanism rotate clockwise along with the bracket 2. When the door leaf A and the door frame are about to close, the ejector rod 10 will be in initial contact with the trigger member 4, and as the clockwise rotation continues, the initial contact between the ejector rod 10 and the trigger member 4 will also evolve into the extrusion of the trigger member 4 on the ejector rod 10, thereby causing the ejector rod 10 to displace. The ejector rod 10 pushes the support plate 11 to displace and compress the second spring 12. During this process, the locking hook 13 displaces towards the unlocking buckle 15 with the support plate 11, and the hook portion of the locking hook 13 swings under the extrusion of the inclined surface on the unlocking buckle 15, and the locking hook 13 separates from the buckle 14. When the ejector rod 10 separates from the trigger member 4, the ejector rod 10 is no longer restricted. At this time, under the tension of the second spring 12, the ejector rod 10 is pushed by the support plate 11 to displace towards the outside of the bracket 2, and the locking hook 13 displaces with the support plate 11, so that the self-locking mechanism is reset and the locking of the pin shaft 3 by the self-locking mechanism is released.

[0041] The structure of the present utility model is not limited to the above embodiments. For example, the blocking mechanism can also adopt the following structure:

[0042] Such as Figures 7 to 8As shown, the blocking mechanism includes a column 5, a blocking rod 6, a sleeve 7, and a first spring 8. The column 5 is fixed to the self-locking mechanism, the sleeve 7 is fixed to the column 5, the first spring 8 is located inside the sleeve 7, one end of the first spring 8 is connected to the sleeve 7 or the column 5, one end of the blocking rod 6 is located inside the sleeve 7 and is connected to the first spring 8, the other end of the blocking rod 6 is exposed outside the sleeve 7 and is located above the engaging groove 2a, the other end of the blocking rod 6 corresponds to the inside of the engaging groove 2a, and the end face of the other end of the blocking rod 6 is a conical surface or a spherical surface. In this structure, when the pin shaft 3 enters or exits from the engaging groove 2a, the pin shaft 3 will exert a squeezing force on the blocking rod 6, so that the blocking rod 6 retracts into the sleeve 7. When the pin shaft 3 is separated from the blocking rod 6, the blocking rod 6 extends. This structure can make the part of the blocking rod 6 corresponding to the inside of the engaging groove 2a longer, and the blocking rod 6 can better block the pin shaft 3.
