Description

Technical Field

[0001] This application belongs to the field of sunshade technology, and particularly relates to an umbrella frame device and an automobile. Background Technology

[0002] Currently, sunshades used in automobiles typically include a handle, ribs, an upper visor, and a lower visor. Both the upper and lower visors are hinged to the ribs, and the lower visor is connected to the body of the handle. The upper visor is positioned at the top of the handle. In some sunshades, the upper visor can move relative to the top of the handle as the ribs open or close. When the ribs are fully open, the upper visor usually rests against the top of the handle or is suspended above the handle by the support of the ribs. In this case, the upper visor is prone to wobbling, which can damage the stability of the ribs and affect the normal use of the sunshade. Summary of the Invention

[0003] The purpose of this application is to provide an umbrella frame device and an automobile, which aims to solve the technical problem in the prior art that when the umbrella ribs are fully extended, the upper part of the umbrella frame is prone to shaking, which damages the stability of the umbrella ribs and thus affects the normal use of the sun umbrella.

[0004] To achieve the above objectives, the technical solution adopted in this application is: an umbrella frame device, including a support mechanism and a movable mechanism. The support mechanism includes a support base and a movable rod. The movable rod is connected to the support base and can rotate around its own axis. The movable mechanism includes a frame assembly and a movable block. The movable block and the movable rod are correspondingly arranged. The frame assembly is hinged to the movable block and the support base respectively. The frame assembly can be unfolded or retracted relative to the support base and drive the movable block to move relative to the movable rod. When the frame assembly is fully unfolded, the movable block and the movable rod are threadedly connected.

[0005] Furthermore, the movable rod is provided with an external thread, the movable block is provided with a connecting hole, and the movable block is provided with a first internal thread on the inner wall of the connecting hole. When the skeleton assembly is fully unfolded, the movable block is sleeved on the movable rod through the connecting hole, and the first internal thread engages with the external thread.

[0006] Furthermore, when the skeleton assembly retracts, with the direction of movement of the movable block as the first direction, the connecting hole is divided into a connected guide section and a threaded section along the first direction. The guide section is tapered along the first direction, and the first internal thread is provided on the inner wall of the threaded section.

[0007] Furthermore, the support mechanism also includes a driver, which is mounted on the support base and connected to the movable rod, for driving the movable rod to rotate so that the external thread engages with the first internal thread.

[0008] Furthermore, the movable mechanism also includes a connecting sleeve, which is hinged to the skeleton assembly and movably sleeved on the movable rod. It can reciprocate along the length of the movable rod to drive the skeleton assembly to unfold or retract. When the skeleton assembly is fully unfolded, the movable rod protrudes from the top of the connecting sleeve.

[0009] Furthermore, the connecting sleeve is provided with a second internal thread, which engages with the external thread so that when the movable rod rotates, it drives the connecting sleeve to reciprocate along the length of the movable rod.

[0010] Furthermore, the connecting sleeve includes a first sleeve body and a second sleeve body. The first sleeve body is fixedly sleeved on the second sleeve body and is hinged to the skeleton assembly. A second internal thread is provided on the second sleeve body. The support mechanism also includes a limiting sleeve, which is fixedly sleeved on the movable rod and located between the second sleeve body and the movable block. When the skeleton assembly is fully extended, the limiting sleeve passes through the first sleeve body and abuts against the second sleeve body.

[0011] Furthermore, the support base is provided with a guide sleeve, which is movably fitted outside the connecting sleeve. When the skeleton assembly is fully extended, the connecting sleeve protrudes from the top of the guide sleeve.

[0012] Furthermore, the skeleton assembly includes a first link, a second link, and a third link. The first link is hinged to the movable block. One end of the second link is hinged to the end of the first link away from the movable block, and the other end of the second link is hinged to the support seat. One end of the third link is hinged to the connecting sleeve, and the other end of the third link is hinged to the torso of the second link.

[0013] Compared with the prior art, the beneficial effects of the umbrella frame device provided in this application are as follows: When the umbrella frame device provided in this application is in use, the skeleton component of the umbrella frame device is used to fix the umbrella fabric. The skeleton component is hinged to the movable block and the support seat respectively. When the skeleton component is unfolded or retracted relative to the support seat, it drives the umbrella fabric to unfold or retract. During the unfolding or retracting process of the skeleton component, it drives the movable block to move relative to the movable rod. Since the movable rod can rotate around its own axis, when the skeleton component is fully unfolded, the movable block and the movable rod are threaded together, so that the movable block is positioned on the movable rod and is not easy to shake. This helps to improve the stability of the umbrella rib assembly and thus effectively ensures the normal use of the umbrella frame device.

[0014] This application also provides an automobile, including a vehicle body and the aforementioned umbrella frame device, which is mounted on the roof of the vehicle body. In use, the frame assembly of the umbrella frame device is used to fix the umbrella fabric. The frame assembly is hinged to a movable block and a support seat. When the frame assembly unfolds or retracts relative to the support seat, it drives the umbrella fabric to unfold or retract. During the unfolding or retracting process, the frame assembly drives the movable block to move relative to the movable rod. Since the movable rod can rotate around its own axis, when the frame assembly is fully unfolded, the movable block and the movable rod are threaded together, positioning the movable block on the movable rod and preventing it from wobbling. This improves the stability of the umbrella frame assembly and effectively ensures the normal use of the umbrella frame device. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] This application provides an umbrella frame device for use with umbrella fabric to provide functions such as sunshade, rain protection, wind protection, UV protection, or decoration. Its application scenarios are not limited, and users can choose according to their actual needs.

[0038] Please refer to the following: Figures 1 to 7 The umbrella frame device provided in the embodiments of this application will now be described. The umbrella frame device includes a support mechanism 10 and a movable mechanism 20. The support mechanism 10 includes a support base 11 and a movable rod 12. The movable rod 12 is connected to the support base 11 and can rotate around its own axis. The movable mechanism 20 includes a frame assembly 30 and a movable block 40. The movable block 40 is correspondingly arranged with the movable rod 12. The frame assembly 30 is hinged to the movable block 40 and the support base 11 respectively. The frame assembly 30 can be unfolded or retracted relative to the support base 11 and drives the movable block 40 to move relative to the movable rod 12. When the frame assembly 30 is fully unfolded, the movable block 40 is threadedly engaged with the movable rod 12.

[0039] Compared with the prior art, the umbrella frame device provided in this application has a frame assembly 30 for fixing the umbrella fabric. The frame assembly 30 is hinged to the movable block 40 and the support base 11 respectively. When the frame assembly 30 is unfolded or retracted relative to the support base 11, it drives the umbrella fabric to unfold or retract. During the unfolding or retracting process of the frame assembly 30, it drives the movable block 40 to move relative to the movable rod 12. Since the movable rod 12 can rotate around its own axis, when the frame assembly 30 is fully unfolded, the movable block 40 is threadedly engaged with the movable rod 12, so that the movable block 40 is positioned on the movable rod 12 and is not easy to shake. This helps to improve the stability of the frame assembly 30 and thus effectively ensures the normal use of the umbrella frame device.

[0040] When the umbrella frame device provided in this application embodiment is used, the support base 11 can be fixed to limit the rotation of the frame assembly 30 around the axis of the movable rod 12 during the unfolding or retracting process, thereby limiting the rotation of the movable block 40 around the axis of the movable rod 12. This makes it easier and smoother for the movable rod 12 and the movable block 40 to be threaded together.

[0041] It should be noted that when the movable rod 12 is connected to the support base 11, the support base 11 can axially limit the movable rod 12, so that the movable rod 12 can only rotate around its own axis and cannot move along its axis. In this case, when the movable block 40 and the movable rod 12 are threadedly engaged, that is, when the skeleton assembly 30 is fully deployed, the movable block 40 and the movable rod 12 no longer move relative to each other, and the movable rod 12 no longer rotates around its own axis. Alternatively, the movable rod 12 can move along its own axis on the support base 11. When the skeleton assembly 30 is deployed to drive the movable block 40 to move relative to the movable rod 12, the movable rod 12 can also move relative to the movable block 40 along its own axis until the skeleton assembly 30 is fully deployed, at which point the movable block 40 and the movable rod 12 are threadedly engaged. Or, when the skeleton assembly 30 is fully deployed, the skeleton assembly 30 no longer drives the movable block 40 to move relative to the movable rod 12. In this case, the movable rod 12 moves relative to the movable block 40 along its own axis and is threadedly engaged with the movable block 40.

[0042] Furthermore, when the movable rod 12 can only rotate around its own axis and cannot move along its axial direction, the movable block 40 is threadedly engaged with the movable rod 12. This engagement exists, but is not limited to, when the skeleton assembly 30 is fully extended. In addition, it can also exist during the process of the skeleton assembly 30 being extended, during the process of the skeleton assembly 30 being retracted, and when the skeleton assembly 30 is fully retracted. In this case, the movable block 40 and the movable rod 12 achieve relative movement through the threaded engagement, thereby satisfying the extension or retraction of the skeleton assembly 30.

[0043] In another embodiment of this application, such as Figures 4 to 7 As shown, the movable rod 12 is provided with an external thread 121, the movable block 40 is provided with a connecting hole 41, and the movable block 40 is provided with a first internal thread 431 on the inner wall of the connecting hole 41. When the skeleton assembly 30 is fully unfolded, the movable block 40 is sleeved on the movable rod 12 through the connecting hole 41, and the first internal thread 431 is engaged with the external thread 121.

[0044] In this embodiment, the movable block 40 may be fitted onto the movable rod 12 through the connecting hole 41 only when the skeleton assembly 30 is fully extended, with the first internal thread 431 engaging with the external thread 121; or the movable block 40 may always be fitted onto the movable rod 12 through the connecting hole 41, with the portion of the movable rod 12 fitted with the connecting hole 41 having the external thread 121, so that the first internal thread 431 always engages with the external thread 121 during the extension or retraction of the skeleton assembly 30; or the movable block 40 may always be fitted onto the movable rod 12 through the connecting hole 41, with the movable rod 12 having the external thread 121 only at a specific position. The specific position refers to the position of the movable rod 12 corresponding to the connecting sleeve 50 when the skeleton assembly 30 is fully extended, while the remaining parts of the movable rod 12 can guide the movement of the movable block 40 during the extension or retraction of the skeleton assembly 30, thereby making the skeleton assembly 30 more stable when it is extended or retracted.

[0045] Furthermore, the movable block 40 is movably positioned at the top of the movable rod 12. When the skeleton assembly 30 retracts, the skeleton assembly 30 drives the movable block 40 to move away from the top of the movable rod 12. When the skeleton assembly 30 unfolds, the skeleton assembly 30 drives the movable block 40 to move closer to the top of the movable rod 12. When the skeleton assembly 30 is fully unfolded, the movable block 40 is threadedly engaged with the top of the movable rod 12. The movable rod 12 is provided with an external thread 121 at least at its top position.

[0046] In some other embodiments, the connecting hole 41 may be provided on the movable rod 12, and the external thread 121 may be provided on the movable block 40. When the skeleton assembly 30 is fully extended, the movable rod 12 is sleeved on the movable block 40 through the connecting hole 41, and the first internal thread 431 cooperates with the external thread 121.

[0047] In another embodiment of this application, such as Figure 7 As shown, during the retraction of the skeleton assembly 30, with the movement direction of the movable block 40 as the first direction, the connecting hole 41 is divided into a guide section 42 and a threaded section 43 that are connected along the first direction. The guide section 42 is gradually narrowed along the first direction, and the first internal thread 431 is provided on the inner wall of the threaded section 43.

[0048] In this embodiment, the connecting hole 41 is divided into a guide section 42 and a threaded section 43 that are connected along the first direction. Thus, when the skeleton assembly 30 unfolds and drives the movable block 40 from the position separated from the movable rod 12 to the position where it is sleeved with the movable rod 12, the movable rod 12 passes through the guide section 42 and the threaded section 43 in sequence. The guide section 42 is tapered along the first direction, which can guide the movable rod 12 to accurately enter the threaded section 43, ensuring a good fit between the first internal thread 431 and the external thread 121.

[0049] In another embodiment of this application, such as Figure 4 and Figure 5 As shown, the support mechanism 10 also includes a driver 13, which is mounted on the support base 11 and connected to the movable rod 12. The driver 13 is used to drive the movable rod 12 to rotate so that the external thread 121 engages with the first internal thread 431.

[0050] In this embodiment, a driver 13 is used to drive the movable rod 12 to rotate, so that the external thread 121 engages with the first internal thread 431, which is reliable, convenient, and labor-saving. Of course, the driver 13 can also be configured to drive the movable rod 12 to rotate in the opposite direction, so that the external thread 121 disengages from the first internal thread 431. The driver 13 is preferably an electric motor.

[0051] In some other embodiments, a knob may be connected to the movable rod 12. Rotating the knob can cause the movable rod 12 to rotate around its own axis, so that the external thread 121 engages with the first internal thread 431. In this way, even if the driver 13 fails to work, the purpose can still be achieved by manually rotating the knob, ensuring the reliability of the umbrella frame device.

[0052] In another embodiment of this application, such as Figure 2 , Figure 4 and Figure 5 As shown, the movable mechanism 20 also includes a connecting sleeve 50, which is hinged to the skeleton assembly 30 and movably sleeved on the movable rod 12. It can reciprocate along the length of the movable rod 12 to drive the skeleton assembly 30 to unfold or retract. When the skeleton assembly 30 is fully unfolded, part of the movable rod 12 protrudes from the top of the connecting sleeve 50.

[0053] In this embodiment, when the skeleton assembly 30 is fully extended, the movable rod 12 protrudes from the top of the connecting sleeve 50 to allow for threaded engagement between the movable rod 12 and the movable block 40. During the retraction of the skeleton assembly 30, the connecting sleeve 50 may be fully fitted onto the movable rod 12 or may protrude from the top of the movable rod 12.

[0054] Specifically, such as Figure 2 and Figure 3As shown, the skeleton assembly 30 includes at least two first skeletons 31, with each pair of first skeletons 31 forming a group. The two first skeletons 31 in each group are arranged symmetrically at 180° around the movable rod 12 as the central axis. The first skeleton 31 includes a first connecting rod 311, a second connecting rod 312, and a third connecting rod 313. One end of the first connecting rod 311 is hinged to the movable block 40, one end of the second connecting rod 312 is hinged to the support base 11, the other end of the first connecting rod 311 is hinged to the other end of the second connecting rod 312, one end of the third connecting rod 313 is hinged to the connecting sleeve 50, and the other end of the third connecting rod 313 is hinged to the body of the second connecting rod 312. When the connecting sleeve 50 moves towards the movable block 40, it pulls the third link 313 inward. This inward movement pulls the second link 312 inward, which in turn pushes the first link 311 inward. As the first link 311 retracts inward, it moves the movable block 40 away from the movable rod 12, thus retracting the frame assembly 30. Conversely, when the connecting sleeve 50 moves away from the movable block 40, it pushes the third link 313 outward. This outward movement pushes the second link 312 outward, which in turn pulls the first link 311 outward. As the first link 311 expands outward, it moves the movable block 40 towards the movable rod 12, thus unfolding the frame assembly 30. When the skeleton assembly 30 is fully extended, the movable block 40 is fitted onto the movable rod 12, and the first internal thread 431 engages with the external thread 121.

[0055] Furthermore, the skeleton assembly 30 also includes at least two second skeletons 32, with each pair of second skeletons 32 forming a group. The two second skeletons 32 in each group are arranged symmetrically at 180° around the movable rod 12 as the central axis. The second skeletons 32 are hinged between the support base 11 and the movable block 40. When the first skeleton 31 retracts, the first connecting rod 311 drives the movable block 40 to move away from the movable rod 12, and the movable block 40 then drives the second skeleton 32 to retract. When the first skeleton 31 unfolds, the first connecting rod 311 drives the movable block 40 to move closer to the movable rod 12, and the movable block 40 then drives the second skeleton 32 to unfold. The extension length of the second skeleton 32 can differ from the extension length of the first skeleton 31, allowing for more diverse unfolded shapes of the skeleton assembly 30. Users can select the number and extension length of the first skeleton 31 and the second skeleton 32 according to their actual needs.

[0056] For example, when the umbrella frame device provided in this application embodiment is applied to a car, there are two sets of first frames 31 and one set of second frames 32. The two sets of first frames 31 are arranged in an X-shape with the axis of the car in the length direction as the axis of symmetry. The second frames 32 are arranged along the width direction of the car. The extension length of the first frame 31 is greater than the extension length of the second frame 32, so that the frame assembly 30 can cover the front and rear of the car after it is unfolded.

[0057] In another embodiment of this application, such as Figure 5 and Figure 6 As shown, the connecting sleeve 50 is provided with a second internal thread 524, which engages with the external thread 121 so that when the movable rod 12 rotates, it drives the connecting sleeve 50 to reciprocate along the length of the movable rod 12.

[0058] In this embodiment, the rotation of the movable rod 12 serves two purposes: first, through the engagement of the external thread 121 and the second internal thread 524, the connecting sleeve 50 is driven to reciprocate along the length of the movable rod 12, thereby causing the skeleton assembly 30 to unfold or retract; second, when the skeleton assembly 30 is fully unfolded, through the engagement of the external thread 121 and the first internal thread 431, the movable rod 12 and the movable block 40 are threadedly connected.

[0059] Furthermore, without affecting the threaded connection between the movable rod 12 and the movable block 40, the connecting sleeve 50 can be extended along the length of the movable rod 12 to cover the part of the movable rod 12 exposed on the support base 11 as much as possible, so as to reduce the corrosion of the external thread 121 on the movable rod 12 by moisture in the air, thereby helping to ensure the reliability of the threaded engagement between the external thread 121 and the second internal thread 524.

[0060] In another embodiment of this application, such as Figure 6 As shown, the connecting sleeve 50 includes a first sleeve body 51 and a second sleeve body 52. ​​The first sleeve body 51 is fixedly sleeved on the second sleeve body 52. ​​The first sleeve body 51 is hinged to the skeleton assembly 30. The second internal thread 524 is provided on the second sleeve body 52. ​​The support mechanism 10 also includes a limiting sleeve 14. The limiting sleeve 14 is fixedly sleeved on the movable rod 12 and is provided between the second sleeve body 52 and the movable block 40. When the skeleton assembly 30 is fully extended, the limiting sleeve 14 passes through the first sleeve body 51 and abuts against the second sleeve body 52.

[0061] In this embodiment, when the movable rod 12 rotates and, through the engagement of the external thread 121 and the second internal thread 524, drives the second sleeve 52 to move towards the movable block 40, the second sleeve 52 drives the first sleeve 51 to move synchronously towards the movable block 40, thereby causing the skeleton assembly 30 to retract. When the limiting sleeve 14 passes through the first sleeve 51 and abuts against the second sleeve 52, the second sleeve 52 stops moving towards the movable block 40, and the movable rod 12 also stops rotating. At this time, the skeleton assembly 30 is in a fully retracted state. The limiting sleeve 14 prevents the second sleeve 52 from detaching from the movable rod 12, and also prevents the skeleton assembly 30 from over-retracting, thus providing a certain degree of protection for the skeleton assembly 30.

[0062] Furthermore, the second sleeve 52 includes a through portion 521 and an abutment portion 522, with a stepped surface 523 formed between the through portion 521 and the abutment portion 522. The first sleeve 51 is fixedly sleeved on the through portion 521 and abuts against the stepped surface 523. When the movable rod 12 rotates and drives the second sleeve 52 to move towards the movable block 40, on the one hand, the second sleeve 52 drives the first sleeve 51 to move through the friction between the through portion 521 and the first sleeve 51; on the other hand, the second sleeve 52 pushes the first sleeve 51 to move through the abutment portion 522. This ensures that the first sleeve 51 and the second sleeve 52 move synchronously without separating from each other.

[0063] Furthermore, the second internal thread 524 can be provided on the through portion 521, or on the abutting portion 522, or simultaneously on both the through portion 521 and the abutting portion 522.

[0064] Furthermore, during the unfolding or retraction of the skeleton assembly 30, the limiting sleeve 14 is always inserted inside the first body 51 and slidably connected to the inner wall of the first body 51. This guides the movement of the first body 51, making the first body 51 move more smoothly and less prone to shaking when moving along the length of the movable rod 12, thereby making the unfolding or retraction of the skeleton assembly 30 more stable and smooth.

[0065] Furthermore, a hinge block 53 is fixedly sleeved on the first body 51, and the hinge block 53 is hinged to the frame assembly 30. Furthermore, the hinge block 53 and the first body 51 are detachably connected by screws, which facilitates adjustment of the relative position between the hinge block 53 and the first body 51.

[0066] In another embodiment of this application, such as Figures 4 to 6 As shown, the support base 11 is provided with a guide sleeve 111, which is movably sleeved outside the connecting sleeve 50. When the skeleton assembly 30 is fully extended, part of the connecting sleeve 50 protrudes from the top of the guide sleeve 111.

[0067] In this embodiment, the guide sleeve 111 guides the movement of the connecting sleeve 50, making the connecting sleeve 50 move more smoothly and less prone to wobbling along the length of the movable rod 12, thereby making the expansion or contraction of the skeleton assembly 30 more stable and smooth. The connecting sleeve 50 protrudes from the top of the guide sleeve 111 to accommodate the installation of the hinge block 53 on the connecting sleeve 50.

[0068] Furthermore, when the skeleton assembly 30 is fully extended, the hinge block 53 abuts against the guide sleeve 111, thus positioning the skeleton assembly 30 and preventing it from over-extension, thereby protecting the skeleton assembly 30.

[0069] Furthermore, when the frame assembly 30 is fully deployed, the movable block 40 is threadedly engaged with the movable rod 12, and the movable block 40 abuts against the side of the hinge block 53 away from the guide sleeve 111. This provides a better fixation effect for the movable block 40, effectively preventing the movable block 40 from shaking, thereby improving the stability of the umbrella rib assembly and ensuring the normal use of the umbrella frame device.

[0070] This application embodiment also provides a car, including a vehicle body and the aforementioned umbrella frame device. The umbrella frame device is installed on the top of the vehicle body and is used in conjunction with the umbrella cloth to cover the top of the vehicle body to block sunlight, effectively reducing the interior temperature and preventing damage to the vehicle body from sun exposure. In use, the frame assembly 30 of the umbrella frame device is used to fix the umbrella cloth. The frame assembly 30 is hinged to the movable block 40 and the support seat 11. When the frame assembly 30 unfolds or retracts relative to the support seat 11, it causes the umbrella cloth to unfold or retract. During the unfolding or retracting process, the movable block 40 moves relative to the movable rod 12. Since the movable rod 12 can rotate around its own axis, when the frame assembly 30 is fully unfolded, the movable block 40 is threadedly engaged with the movable rod 12, positioning the movable block 40 on the movable rod 12 and preventing it from wobbling. This improves the stability of the frame assembly 30, effectively ensuring the normal use of the umbrella frame device and thus effectively guaranteeing its protective function for the vehicle body.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
