Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to rotary connection mechanisms and movable devices. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges play an important role in automobiles, such as door hinges, hood hinges, and seat hinges.

[0003] In related technologies, some vehicles are equipped with split tailgates. The opening and closing of split tailgates are generally controlled by electric struts. During the opening and closing process, the electric struts only provide the kinetic energy for opening and closing, and do not provide the force to limit the over-opening. The tailgate stops moving because the hinge structure itself limits the over-opening angle of the tailgate.

[0004] However, the hinges of this technology may develop paint chips and friction marks due to long-term impacts during the limiting process, affecting the limiting accuracy and appearance quality of the hinges. Utility Model Content

[0005] To solve or partially solve the problems existing in the related technologies, this application provides a rotary connection mechanism and a movable device, which can improve the limiting accuracy and service life of the rotary connection mechanism.

[0006] The first aspect of this application provides a rotary connection mechanism, comprising:

[0007] The first movable component, the second movable component, and the rotating shaft are rotatably mounted on the rotating shaft. The first movable component is provided with a first limiting part, and the second movable component is provided with a second limiting part. The first limiting part is used to abut against the second limiting part to limit the first movable component and the second movable component to a preset rotation angle.

[0008] The first limiting part is provided with a limiting block, which is used to abut against the second limiting part and is engaged with the first limiting part.

[0009] In one implementation, the first limiting part includes a mounting block, the mounting block has a mounting hole, the inner wall of the mounting hole has a limiting groove, and the limiting block includes a main body and a plug-in part, the plug-in part being used to be inserted into the mounting hole;

[0010] The plug portion is provided with a limiting protrusion. When the plug portion is assembled into the mounting hole, the limiting protrusion and the limiting groove interfere with each other.

[0011] In one implementation, the limiting groove ring is disposed on the inner wall of the mounting hole and is arranged in a spiral shape;

[0012] The limiting protrusions are distributed circumferentially along the insertion part or are provided on both radial sides of the insertion part.

[0013] In one implementation, the limiting protrusion is inclined relative to the insertion part, and the inclination direction is opposite to the insertion direction of the insertion part.

[0014] In one implementation, the end of the plug-in portion away from the main body is provided with a flange structure, and the outer edge of the flange structure is used to contact the inner wall of the tail end of the mounting hole to close the tail end opening of the mounting hole.

[0015] In one implementation, the middle part of the plug portion is provided with a spacer groove, the spacer groove extends along the plugging direction of the plug portion, and the limiting protrusion is provided on both sides of the spacer groove.

[0016] In one implementation, the first limiting part is provided with a supporting mating part, the mounting hole is opened in the supporting mating part, and the main body is fitted to the supporting mating part.

[0017] In one implementation, the first limiting part is disposed close to the rotating shaft, and the second limiting part is disposed away from the rotating shaft. The first limiting part and the second limiting part have a preset protrusion direction. When the two limiting parts abut against each other, the included angle between the protrusion directions of the two limiting parts is an acute angle or an obtuse angle, and the area near the middle of the first limiting part abuts against the area near the end of the second limiting part.

[0018] In one implementation, the limiting block is made of plastic.

[0019] A second aspect of this application provides a mobile device, including a device body and a rotating component; the rotating component is mounted on the device body via a rotating connection mechanism as described in the first aspect above.

[0020] The technical solution provided in this application may include the following beneficial effects:

[0021] The rotary connection mechanism provided in this application includes a first movable member, a second movable member, and a rotating shaft. The first and second movable members are rotatably mounted on the rotating shaft. The first movable member has a first limiting part, and the second movable member has a second limiting part. The first limiting part abuts against the second limiting part to limit the first and second movable members to a preset rotation angle. The first limiting part has a limiting block that abuts against the second limiting part and is engaged with the first limiting part. With this configuration, because the limiting block is engaged with the first limiting part, compared with related technologies, the engaging method allows the limiting block to be more stably fixed to the first limiting part. It is less prone to loosening or falling off under external impact, natural aging, etc., which helps improve the limiting accuracy and service life of the rotary connection mechanism.

[0022] Furthermore, the first limiting part includes a mounting block with a mounting hole and a limiting groove on the inner wall of the mounting hole. The limiting block includes a main body and a plug-in part, which is inserted into the mounting hole. The plug-in part has a limiting protrusion. When the plug-in part is assembled into the plug-in hole, the limiting protrusion interferes with the limiting groove. This configuration increases the friction coefficient of the inner wall of the mounting hole, making the locking between the limiting protrusion and the threaded hole more secure, which is beneficial for increasing the pull-out force. In addition, compared with related technologies, the number of limiting protrusions can be reduced while maintaining the same pull-out force, thus saving installation space.

[0023] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0035] Hinges in related technologies often develop paint chipping and friction marks due to prolonged impacts during the limiting process, affecting the limiting accuracy and appearance of the hinge. To address these issues, this application provides a rotary connection mechanism and a movable device that improves the limiting accuracy and service life of the rotary connection mechanism.

[0036] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the rotating connection mechanism in its first state, as shown in an embodiment of this application.

[0038] Figure 2 This is a schematic diagram of the rotating connection mechanism in the second state as shown in the embodiment of this application.

[0039] See Figure 1 This application provides a rotating connection mechanism, which includes a first movable member 100, a second movable member 200, and a rotating shaft. The first movable member 100 and the second movable member 200 are rotatably mounted on the rotating shaft. The first movable member 100 is provided with a first limiting part 110, and the second movable member 200 is provided with a second limiting part 210. The first limiting part 110 is used to abut against the second limiting part 210 to limit the first movable member 100 and the second movable member 200 to a preset rotation angle. The first limiting part 110 is provided with a limiting block 112, which is used to abut against the second limiting part 210 and is engaged with the first limiting part 110.

[0040] This application Figure 1 In the middle, the first movable part 100 and the second movable part 200 are in the first state, which is also the state when the first movable part 100 and the second movable part 200 are in free movement; Figure 2 In the middle, the first movable part 100 and the second movable part 200 are in the second state, which is also the state when the first movable part 100 and the second movable part 200 are in the limit position.

[0041] The rotary connection mechanism provided in this application, since the limiting block 112 is snapped into the first limiting part 110, compared with related technologies, the snapping method can make the limiting block 112 more stably fixed in the first limiting part 110. It is not easy to loosen or fall off when subjected to external impact, natural aging, etc., which is conducive to improving the limiting accuracy and service life of the rotary connection mechanism.

[0042] The rotating connection mechanism of this embodiment can also be called a hinge. This rotating connection mechanism can be applied to a door, such as a double-opening tailgate or a single-opening tailgate of a vehicle. When the door is opened until the first limiting part 110 and the second limiting part 210 on the rotating connection mechanism abut against each other, the door can be limited to a preset opening angle.

[0043] Figure 3 This is a schematic diagram of the structure of the limiting block shown in the embodiment of this application; Figure 4 This is an assembly diagram of the limiting block shown in an embodiment of this application.

[0044] See Figure 3 and Figure 4 In some embodiments, the first limiting part 110 includes a mounting block 111, the mounting block 111 has a mounting hole 1111, the inner wall of the mounting hole 1111 has a limiting groove, the limiting block 112 includes a main body and a plug-in part, the plug-in part is used to be inserted into the mounting hole 1111; the plug-in part has a limiting protrusion 1121, when the plug-in part is assembled into the mounting hole 1111, the limiting protrusion 1121 and the limiting groove interfere with each other, for example, the limiting protrusion 1121 can extend into the limiting groove to achieve mutual locking.

[0045] The main body and the insertion part are integrally molded. The main body is provided on the side facing the second limiting part 210 at the first limiting part 110. When the first limiting part 110 and the second limiting part 210 are rotated to approach each other, the main body can abut against the second limiting part 210.

[0046] When the plug is assembled into the mounting hole 1111, the limiting protrusion 1121 of the plug can abut against the limiting groove, making the connection between the plug and the mounting hole 1111 more stable, avoiding displacement between the plug and the mounting hole 1111 along the axial direction of the mounting hole 1111, and thus preventing the plug from loosening or falling off.

[0047] In this embodiment, the mounting hole 1111 can be a circular through hole, and the plug part is columnar. The length of the plug part is less than or equal to the opening depth of the mounting hole 1111. When the plug part is assembled into the mounting hole 1111, the plug part can completely fill the mounting hole 1111.

[0048] See also Figure 3 and Figure 4In some embodiments, the limiting groove ring disposed on the inner wall of the mounting hole 1111 can be arranged in a spiral shape. For example, the limiting groove can be an internal threaded hole 1112. The limiting protrusions 1121 are distributed circumferentially along the insertion part, and the limiting protrusions 1121 are provided in at least two layers along the length direction X of the insertion part. With this arrangement, the friction coefficient of the inner wall of the mounting hole 1111 can be increased, making the engagement between the limiting protrusions 1121 and the threaded hole more secure. Under the condition of constant pull-out force, compared with related technologies, the number of limiting protrusions 1121 can be reduced, which helps to save the engagement space in the mounting hole 1111.

[0049] In some embodiments, the threaded hole interferes with the limiting protrusion 1121 by about 0.5 mm at about 50% depth per turn. This can further increase the pull-out force of the limiting block 112 in the mounting hole 1111 and improve the installation stability of the limiting block 112.

[0050] In some embodiments, the limiting protrusion 1121 is inclined relative to the insertion portion, and the inclination direction is opposite to the length direction X of the insertion portion. With this configuration, the limiting protrusion 1121 is arranged in a "barb" shape, which can improve the pull-out force with a smaller number of limiting protrusions 1121, and can further reduce the installation space of the insertion portion.

[0051] See also Figure 3 and Figure 4 In some embodiments, a flange structure 1122 is provided at the end of the plug-in portion away from the main body. The flange structure 1122 can be a disc-shaped structure perpendicular to the plug-in portion. The outer edge of the flange structure 1122 is used to contact the inner wall of the mounting hole 1111 to close the tail opening 1113 of the mounting hole 1111. The tail opening 1113 of the mounting hole 1111 is also the opening on the side of the mounting hole 1111 facing away from the main body. With this arrangement, since the diameter of the flange structure 1122 is close to the inner diameter of the mounting hole 1111, after the plug-in portion is assembled with the mounting hole 1111, the flange structure 1122 can cover or close the tail opening 1113 of the mounting hole 1111, making the area of ​​the first limiting portion 110 on the side of the tail opening 1113 flatter. No holes or gaps will appear at the tail opening 1113, which can prevent dust from entering the mounting hole 1111 and improve the appearance.

[0052] See also Figure 3 and Figure 4In some embodiments, the first limiting part 110 is provided with a supporting mating part, which can be a mounting platform 1114 provided on the first limiting part 110. A mounting hole 1111 is formed on the mounting platform 1114, and the main body is attached to the mounting platform 1114 through surface contact. When the insertion part is fully inserted into the mounting hole 1111, the mounting platform 1114 and the limiting block 112 are in contact with each other, thus improving the installation stability of the limiting block 112 on the first limiting part 110. The limiting block 112 abuts against the second limiting part 210, and the supporting mating part supports the limiting block 112, thereby preventing relative displacement between the limiting block 112 and the first limiting part 110 when bearing force, and improving the stability of the limiting block 112 during the bearing process.

[0053] In some embodiments, a spacer groove 1123 is provided in the middle of the insertion part along the length direction X of the insertion part. The spacer groove 1123 extends along the length direction X of the insertion part, and a limiting protrusion 1121 is provided on both sides of the spacer groove 1123. The spacer groove 1123 divides the insertion part into at least two parallel free bodies, which can move along the length direction X perpendicular to the insertion part. With this arrangement, the two parallel free bodies can contract or expand. In the contracted state, it is convenient to travel along the axial direction of the mounting hole 1111. When the insertion part is inserted into the mounting hole 1111, the expanding force makes the limiting protrusion 1121 tightly engage with the limiting groove.

[0054] In some embodiments, the middle part of the plug portion of this application may not have a spacer groove 1123 along the length direction X of the plug portion. Instead, the extension length of the limiting protrusion 1121 is increased, so that the limiting protrusions 1121 on both sides or in the circumferential direction of the plug portion have a larger deformation. The plug portion is fixed to the mounting hole 1111 by extrusion deformation. The larger deformation allows the plug portion to smoothly enter the mounting hole 1111 and tightly engage with the limiting groove on the inner wall of the mounting hole 1111. Moreover, the tail end of the plug portion can also contact the edge of the opening to achieve closure of the opening.

[0055] See Figure 1 and Figure 2 In some embodiments, the first movable member 100 may include a first plate-shaped body and a first mounting sleeve 120 connected to the first plate-shaped body, and the second movable member 200 may include a second plate-shaped body and a second mounting sleeve 220 connected to the second plate-shaped body. The first mounting sleeve 120 and the second mounting sleeve 220 are coaxially arranged and sleeved on the rotating shaft 300. The first limiting part 110 is disposed near the rotating shaft 300, and the second limiting part 210 is disposed away from the rotating shaft. Specifically, the first limiting part 110 may be fixed to the first mounting sleeve 120, and the second limiting part 210 may be disposed on the second plate-shaped body. The first limiting part 110 and the first plate-shaped body are integrally formed metal structures, and the second limiting part 210 and the second plate-shaped body are integrally formed metal structures.

[0056] See Figure 2 In some embodiments, the first plate-shaped body and the second plate-shaped body can be configured with a predetermined shape to fit and be installed on a corresponding mobile device. The first limiting portion 110 and the second limiting portion 210 have preset protrusion directions; the first limiting portion protrudes in a direction away from the pivot axis, and the second limiting portion protrudes in a direction away from the second plate-shaped body. When the two limiting portions are in contact, the included angle between the protrusion directions of the two limiting portions is an acute angle or an obtuse angle, for example, Figure 2 In the middle, the center line of the first limiting part is L1, the center line of the second limiting part 210 is L2, and the included angle between L1 and L2 is an acute angle or an obtuse angle.

[0057] In some embodiments, the region near the middle of the first limiting part 110 abuts against the region near the end of the second limiting part 210. This arrangement can buffer the impact force when the first limiting part 110 and the second limiting part 210 abut against each other, thereby reducing the local stress concentration of the first limiting part 110 and the second limiting part 210.

[0058] In this embodiment, the two movable parts are made of metal and are integrally molded metal parts, while the limiting block 112 is made of plastic. When the plastic limiting block 112 abuts against the metal limiting part, the plastic material has low hardness and flexibility, which not only buffers the impact force and reduces noise when the two abut, but also avoids friction marks or wear, thereby improving the limiting accuracy.

[0059] The rotating connection mechanism of this application has been described above. Accordingly, this application also provides a mobile device, which includes a device body and a rotating component; the rotating component is mounted on the device body through the rotating connection mechanism of the above embodiment.

[0060] The movable device can be a vehicle, aircraft, engineering machinery, ship, etc. When the movable device of this application is a vehicle, the vehicle includes a body and a door, the door being a rotating component, and the body and door are connected by a rotating connection mechanism; the first plate-shaped main body of the first movable member 100 has a first connecting hole 130, and the second plate-shaped main body of the second movable member 200 has a second connecting hole 230; the first movable member 100 can be fixed to the fuselage through the first connecting hole 130 and fasteners passing through the first connecting hole 130, and the second movable member 200 can be fixed to the door through the second connecting hole 230 and fasteners passing through the second connecting hole 230. The door of this application can be a double-opening tailgate of a vehicle.

[0061] In related technologies, the opening and closing of a vehicle's split tailgate is generally controlled by an electric strut. During the opening and closing process, the electric strut only provides the kinetic energy for opening and closing, and does not provide the force to limit over-opening. The rotary connection mechanism of this application, when the two doors are opened until the two limiting parts abut against each other, limits the two doors to a preset opening angle. That is, the rotary connection mechanism itself can limit the over-opening angle of the doors and stop them at the predetermined angle. Compared with related technologies, the limiting block of the rotary connection mechanism is more stably fixed on the first limiting position, and is less prone to loosening or falling off when subjected to external impacts or natural aging, thereby improving vehicle quality and user experience.

[0062] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
