Description

Technical field

[0001] The invention relates to a limit spring, a hanging ring, a curtain driving device and a curtain assembly. [Background Technology]

[0002] Traditionally, curtains are often opened and closed manually by the user, a reliance on manual operation that is quite inconvenient. To improve the user experience, curtain actuators that can electrically control the opening and closing of curtains have emerged on the market. These actuators can be mounted on a curtain rod and move between the two ends of the rod, thereby controlling the opening and closing of the curtains. The curtain actuator can be mounted on the curtain rod via a hanging ring. Specifically, the hanging ring can have two buckles that can snap together to form a closed ring and can also move apart relative to each other to form an opening for connection to the curtain rod. However, once the two buckles are engaged, they can easily become loose along their circumferential position, causing the buckles to disengage, disrupting the connection between the curtain actuator and the curtain rod and preventing proper operation.

[0003] Therefore, it is necessary to improve the prior art to overcome the above defects. [Summary of the invention]

[0004] The object of the present invention is to provide a limit spring, a hanging ring, a curtain driving device and a curtain assembly, so as to solve the technical problem that the hanging ring buckle in the existing curtain driving device is easy to be disengaged.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A limit spring is characterized in that the limit spring includes a first diameter section and a second diameter section, the first diameter section and the second diameter section are respectively located at two ends of the limit spring, and the diameter of the first diameter section is not equal to the diameter of the second diameter section.

[0007] In this solution, the limit spring has a first diameter section and a second diameter section at each end. The spring diameters within the first and second diameter sections are equal, while the diameters between the first and second diameter sections are different. When applied to a hanging ring, this spring provides circumferential positioning at the hanging ring's engagement point and facilitates the opening and removal of the hanging ring.

[0008] Preferably, the limit spring further includes a transition diameter section, wherein the transition diameter section is located between the first diameter section and the second diameter section, and the diameter of the transition diameter section gradually increases from one end to the other end.

[0009] Preferably, the limit spring can be sleeved on the outer surface of the component to be limited.

[0010] In this solution, the component to be limited is limited.

[0011] A hanging ring, comprising a first buckle and a second buckle, wherein one end of the first buckle is connected to one end of the second buckle, and the other end of the first buckle and the other end of the second buckle are engaged with each other to form a locking section; the hanging ring is characterized in that:

[0012] The hanging ring further includes an elastic member, which is sleeved and wrapped around the outer surface of the engaging section, and the elastic member can be moved to expose the engaging section. The elastic member can be moved as a whole to an area on the hanging ring where the engaging section is exposed, or can be compressed to expose the engaging section, or can be compressed and moved as a whole at the same time.

[0013] In this solution, when the elastic member moves to a point where it no longer overlaps with the tail of either the first buckle or the second buckle, the first buckle and the second buckle can move relative to each other, thereby opening the hanging loop; when it overlaps with the locking section of the first buckle and the second buckle, the elastic member can limit the relative movement of the first buckle and the second buckle, thereby preventing the hanging loop buckle from being disengaged.

[0014] Preferably, the elastic member includes a first diameter section and a second diameter section, the first diameter section and the second diameter section are respectively located at two ends of the elastic member, and the diameter of the first diameter section is smaller than the diameter of the second diameter section;

[0015] The diameter of the engaging section is larger than the diameter of the first diameter section and smaller than the diameter of the second diameter section.

[0016] In this solution, the inner diameters of the first diameter segment and the second diameter segment are equal, and the diameter of the first diameter segment is smaller than the diameter of the second diameter segment; the diameter of the locking segment is between the diameter of the first diameter segment and the diameter of the second diameter segment, and the elastic member can be sleeved on the locking segment and can move relative to the locking segment, thereby exposing the tail of either the first buckle or the second buckle.

[0017] Preferably, one of the first buckle and the second buckle is interference fit with the first diameter segment.

[0018] In this solution, the first diameter section can be interference fit with the first buckle or the second buckle, so that the elastic member can be clamped to the first buckle or the second buckle, and the clamping section can be wrapped to limit the position.

[0019] Preferably, the elastic member further includes a transition diameter section, wherein the transition diameter section is located between the first diameter section and the second diameter section, and the diameter of the transition diameter section gradually increases from one end to the other end.

[0020] In this solution, the transition diameter section can form a step surface to prevent the elastic member from moving.

[0021] Preferably, the first buckle further includes a first smooth section, the second buckle further includes a second smooth section, the first smooth section, the locking section and the second smooth section are connected in sequence; the diameter of the first smooth section and the diameter of the second smooth section are both smaller than the diameter of the locking section.

[0022] In this solution, the diameter of the engaging section is larger than the diameter of other parts of the hanging ring, which not only increases the engaging contact area and improves the connection effect, but also enhances the wrapping of the elastic part and improves the limiting effect.

[0023] Preferably, the elastic member is of a constant diameter structure, a protrusion is provided on the outer wall of the first clip or the outer wall of the second clip, and the protrusion is located below the elastic member, and the protrusion is used to limit the position of the elastic member.

[0024] In this solution, the elastic member may also be of a constant diameter structure, and the position of the elastic member on the hanging ring is limited by the protrusion, so that the elastic member can be wrapped around the engaging section.

[0025] Preferably, the elastic member is a spring.

[0026] In this solution, the elastic member may be a spring, which is easily compressed to produce deformation and is also easy to move relative to the hanging ring; and the elastic member is a flexible member that can adapt to the shape of the hanging ring and improve the limiting effect.

[0027] Preferably, the end of the first clip has a first clipping surface, the end of the second clip has a second clipping surface, and the first clipping surface and the second clipping surface are S-shaped surfaces that fit together.

[0028] In this solution, the S-shaped surface can limit the relative rotation of the first buckle and the second buckle, and the matching elastic member can limit the movement of the first buckle and the second buckle in three dimensions.

[0029] Preferably, the first buckle and the second buckle are both semicircular ring structures; one end of the first buckle and one end of the second buckle are hinged to each other.

[0030] Preferably, a plurality of balls are sleeved on the middle portion of the first buckle, and the balls are capable of rolling around the first buckle.

[0031] In this solution, when the hanging ring moves relative to the curtain rod, the ball contacts the curtain rod and rolls relative to it, reducing the resistance to the movement of the hanging ring and improving the movement efficiency.

[0032] Preferably, protrusions are respectively provided on the outer side walls on both sides of the first buckle, and the plurality of balls are located between two of the protrusions.

[0033] In this solution, the position of the roller can be limited by the protrusion, so that the ball is located at the upper position of the first buckle to contact the curtain rod.

[0034] A curtain driving device is characterized by comprising:

[0035] A host, comprising a housing, a control unit, and a roller unit, wherein the roller unit is mounted on the housing, and the control unit is connected to the roller unit to drive the roller unit to rotate; and

[0036] According to the above-mentioned hanging ring, the hanging ring is extended outwardly from the shell, and the hanging ring is used to be sleeved on the curtain rod.

[0037] In this solution, by adopting the above-mentioned hanging ring, not only can the curtain drive device be hung on the curtain rod, so that the roller part can act on the curtain rod and drive the curtain drive device to move, thereby opening and closing the curtain; but the elastic part of the hanging ring can also limit the relative movement of the first buckle and the second buckle, thereby improving the stability and reliability of the connection.

[0038] Preferably, the elastic member includes a first diameter section and a second diameter section, the diameter of the first diameter section is smaller than the diameter of the second diameter section, and the first diameter section is located above the second diameter section.

[0039] In this solution, the small diameter in the elastic part is connected to the buckle located above the hanging ring, so that one end of the elastic part can be fixed relatively to the buckle, and the elastic part is wrapped in the snap section to limit the hanging ring; when the hanging ring needs to be opened, the elastic part can be moved to the buckle above to avoid operation and avoid interference with the lower components.

[0040] A curtain assembly is characterized in that the curtain assembly includes the above-mentioned hanging ring, or includes the above-mentioned curtain driving device; the curtain assembly also includes a curtain rod, and the hanging ring is sleeved on the curtain rod.

[0041] In this solution, by adopting the above-mentioned hanging ring or curtain driving device, not only can the curtain driving device be hung on the curtain rod, so that the roller part can act on the curtain rod and drive the curtain driving device to move, thereby opening and closing the curtain; but the elastic part of the hanging ring can also limit the relative movement of the first buckle and the second buckle, thereby improving the stability and reliability of the connection.

[0042] Compared with the prior art, the present invention has the following beneficial effects: when the elastic member moves to a point where it no longer overlaps with the tail of either the first buckle or the second buckle, the first buckle and the second buckle can move relative to each other, thereby opening the hanging loop; when it overlaps with the snap-fit ​​section of the first buckle and the second buckle, the elastic member can limit the relative movement of the first buckle and the second buckle, thereby preventing the hanging loop buckle from being disengaged.

[0066] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0067] The embodiment of the present invention provides a limit spring 10, such as Figure 2 As shown, the limit spring 10 includes a first diameter section 110 and a second diameter section 120 , which are respectively located at two ends of the limit spring 10 , and the diameter of the first diameter section 110 is different from the diameter of the second diameter section 120 .

[0068] The spring diameters within the first diameter section 110 and the second diameter section 120 are equal, while the diameters between the first diameter section 110 and the second diameter section 120 are different. In a specific implementation, the spring can be sleeved onto the outer surface of the component to be limited, thereby limiting the circumferential position of the component to be limited.

[0069] As a preferred implementation method, Figure 2 As shown, the limit spring 10 further includes a transition diameter section 130 , which is located between the first diameter section 110 and the second diameter section 120 , and the diameter of the transition diameter section 130 gradually increases from one end to the other.

[0070] The embodiment of the present invention further provides a hanging ring 20, which can be used in a curtain driving device 30, connecting the curtain driving device 30 to the curtain rod and performing relative movement with the curtain rod to open or close the curtain on the curtain rod. Figure 1 and Figure 3 As shown, the hanging ring 20 may include a first buckle 210 and a second buckle 220, one end of the first buckle 210 is connected to one end of the second buckle 220, and the other end of the first buckle 210 and the other end of the second buckle 220 are engaged with each other to form a locking section 240.

[0071] like Figure 1 and Figure 3 As shown, the first buckle 210 and the second buckle 220 can both be semicircular ring structures. When the first buckle 210 and the second buckle 220 are connected, they form a ring structure, and the curtain rod can pass through the ring-shaped hanging ring 20. Among them, one end of the first buckle 210 and one end of the second buckle 220 can be hinged to each other, so that the first buckle 210 and the second buckle 220 at the engaging section 240 can rotate relative to each other to form an opening, which facilitates the removal and installation of the hanging ring 20.

[0072] The following further describes the embodiment of the present invention by taking the first buckle 210 as the buckle located at the top and the second buckle 220 as the buckle located at the bottom.

[0073] like Figure 1 As shown, the hanging ring 20 further includes an elastic member 230 . The elastic member 230 is sleeved and wrapped around the outer surface of the locking section 240 , and the elastic member 230 can be moved to expose the locking section 240 .

[0074] In a specific implementation, the elastic member 230 can be moved above the engaging section 240 and positioned on the first buckle 210; or it can be moved below the engaging section 240 and positioned on the second buckle 220, thereby exposing the engaging section 240 and enabling relative movement between the first buckle 210 and the second buckle 220. The movement of the elastic member 230 can be achieved by moving the entire elastic member 230 to an area on the hanging ring 20 where the tail portion is exposed, by compressing the elastic member 230 to expose the tail portion, or by simultaneously compressing and moving the entire elastic member 230.

[0075] When the elastic member 230 moves to a point where it no longer overlaps with the tail of either the first buckle 210 or the second buckle 220, the first buckle 210 and the second buckle 220 can move relative to each other, thereby opening the hanging ring 20; when it overlaps with the snap-fit ​​section of the first buckle 210 and the second buckle 220, the elastic member 230 can limit the relative movement of the first buckle 210 and the second buckle 220, specifically the movement in the direction perpendicular to the snap-fit ​​surface, thereby preventing the hanging ring 20 from being snapped off.

[0076] As a preferred embodiment, the elastic member 230 can be an incomplete equal-diameter structure, and the elastic member 230 includes a first diameter section 231 and a second diameter section 232. The first diameter section 231 and the second diameter section 232 are respectively located at the two ends of the elastic member 230, and the diameter of the first diameter section 231 is smaller than the diameter of the second diameter section 232; the diameter of the locking section 240 is larger than the diameter of the first diameter section 231 and smaller than the diameter of the second diameter section 232.

[0077] like Figure 2 and Figure 3 As shown, the inner diameter of the first diameter section 231 and the inner diameter of the second diameter section 232 are equal, while the diameters between the first diameter section 231 and the second diameter section 232 are not equal. Specifically, the diameter of the first diameter section 231 is smaller than the diameter of the second diameter section 232. When the elastic member 230 is sleeved on the locking section 240, the elastic member 230 can be wrapped around the locking section 240, and a certain gap is left between the elastic member 230 and the locking section 240, so that the elastic member 230 is easy to move.

[0078] As a preferred embodiment, one of the first buckle 210 and the second buckle 220 is interference-fitted with the first diameter section 231. Thus, the elastic member 230 can be snapped onto the first buckle 210 or the second buckle 220 and wrap around the engaging section 240 to limit the position.

[0079] In a specific implementation, the first diameter section 231 of the elastic member 230 can have an interference fit with the first buckle 210 and a clearance fit with the second buckle 220. When the elastic member 230 needs to be moved to expose the engaging section 240, the elastic member 230 can be moved upward from the second buckle 220 to the first buckle 210. During this movement, the elastic member 230 can be compressed to a certain length, and the first diameter section 231 of the elastic member 230 can be deformed to a certain extent, allowing the first diameter section 231 to move relative to the first buckle 210. As a result, the elastic member 230 can move as a whole relative to the first buckle 210 and move to a position on the first buckle 210 other than the engaging section 240. During this movement, the first diameter section 231 of the elastic member 230 can also be fixed relative to the first buckle 210, and the engaging section 240 can be exposed by compressing the elastic member 230. Alternatively, during the movement, the elastic member 230 may not be compressed, but may move as a whole relative to the first buckle 210 and move to a position on the first buckle 210 other than the engaging section 240 .

[0080] In a specific implementation, the first diameter section 231 of the elastic member 230 can have an interference fit with the second buckle 220 and a clearance fit with the first buckle 210. When the elastic member 230 needs to be moved to expose the engaging section 240, the elastic member 230 can be moved downward from the first buckle 210 to the second buckle 220. During this movement, the elastic member 230 can be compressed to a certain length, and the first diameter section 231 of the elastic member 230 can be deformed to a certain extent, causing the first diameter section 231 to move relative to the second buckle 220. As a result, the elastic member 230 can move as a whole relative to the second buckle 220 and move to a position on the second buckle 220 other than the engaging section 240. During this movement, the first diameter section 231 of the elastic member 230 can also be fixed relative to the second buckle 220, and the engaging section 240 can be exposed by compressing the elastic member 230. Alternatively, during the movement, the elastic member 230 may not be compressed, but may move as a whole relative to the second buckle 220 and move to a position on the second buckle 220 other than the engaging section 240 .

[0081] Among them, such as Figure 4 As shown, the second buckle 220 is used to connect with other components of the curtain driving device 30. In order to facilitate human operation and avoid interference with other components below, the elastic member 230 is preferably moved to the first buckle 210 above.

[0082] As a preferred implementation method, Figure 2 As shown, the elastic member 230 further includes a transition diameter section 233, which is located between the first diameter section 231 and the second diameter section 232, and the diameter of the transition diameter section 233 gradually increases from one end to the other. Figure 2 , which is a schematic diagram of the elastic member 230 , the transition diameter section 233 can form a step surface between the first diameter section 231 and the second diameter section 232 , thereby preventing the elastic member 230 from moving.

[0083] As a preferred implementation method, Figure 3 As shown, the first buckle 210 also includes a first smooth section 211, and the second buckle 220 also includes a second smooth section 221. The first smooth section 211, the locking section 240 and the second smooth section 221 are connected in sequence; the diameter of the first smooth section 211 and the diameter of the second smooth section 221 are both smaller than the diameter of the locking section 240.

[0084] In a specific implementation, the first diameter section 231 can be connected to the first smooth section 211. The diameter of the first smooth section 211 is smaller than the diameter of the engaging section 240. This allows the elastic member 230 to be restrained at the first diameter section 231, preventing it from sliding downward and allowing it to remain at the engaging section 240. The second diameter section 232 can be positioned at least within the engaging section 240 to prevent the buckle from disengaging. For example, if the engaging section 240 has a diameter of 3.4 mm, and the diameters of the first smooth section 211 and the second smooth section 221 are smaller than 3.4 mm, the diameter of the first diameter section 231 is 3.2 mm, and the diameter of the second diameter section 232 is 3.5 mm.

[0085] As another preferred embodiment, the elastic member 230 has a uniform diameter structure, and a protrusion is provided on the outer wall of the first buckle 210 or the outer wall of the second buckle 220, and the protrusion is located below the elastic member 230. The protrusion is used to limit the position of the elastic member 230. Thus, the elastic member 230 can be wrapped around the engaging section 240.

[0086] As a preferred embodiment, the elastic member 230 is a spring.

[0087] The spring is easily compressed to produce deformation and is also easy to move relative to the hanging ring 20; and the elasticity is a flexible part that can adapt to the shape of the hanging ring 20 to enhance the limiting effect.

[0088] As a preferred implementation method, Figure 3As shown, the end of the first clip 210 has a first engaging surface, and the end of the second clip 220 has a second engaging surface. The first and second engaging surfaces are mutually mating S-shaped surfaces. This increases the engaging area and improves the reliability of the engagement. It also limits relative rotation between the first and second clips 210, 220. The elastic member 230 can restrict movement of the first and second clips 210, 220 in three dimensions.

[0089] As a preferred implementation method, Figure 3 As shown, a plurality of balls 250 are sleeved on the middle portion of the first buckle 210 , and the balls 250 can roll around the first buckle 210 .

[0090] When the hanging ring 20 moves relative to the curtain rod, the ball 250 contacts the curtain rod and rolls relative to it, thereby reducing the resistance to the movement of the hanging ring 20 and improving the movement efficiency.

[0091] As a preferred implementation method, Figure 3 As shown, protrusions 260 are respectively provided on the outer side walls on both sides of the first buckle 210, and a plurality of balls 250 are located between the two protrusions 260. Thus, the balls 250 are located at the upper position of the first buckle 210 to contact the curtain rod.

[0092] In specific implementation, Figure 3 As shown, the protrusion 260 may be protruded from the inner surface of the first buckle 210 .

[0093] The embodiment of the present invention further provides a curtain driving device 30, comprising:

[0094] The host 310 includes a housing, a control unit, and a roller unit. The roller unit is mounted on the housing. The control unit is connected to the roller unit to drive the roller unit to rotate.

[0095] According to the above-mentioned hanging ring 20, the hanging ring 20 is extended outwardly from the housing, and the hanging ring 20 is used to be sleeved on the curtain rod.

[0096] In practice, the roller portion engages with the curtain rod, allowing it to move relative to the curtain rod under the control of the control unit. By using the aforementioned hanging ring 20, not only can the curtain drive device 30 be hung on the curtain rod, allowing the roller portion to act on the curtain rod and drive the curtain drive device 30 to move, thereby opening and closing the curtain, but the elastic member 230 of the hanging ring 20 also limits the relative movement of the first buckle 210 and the second buckle 220, thereby improving the stability and reliability of the connection.

[0097] like Figure 4 As shown, two hanging rings 20 are provided on the upper portion of the curtain driving device 30, and the two hanging rings 20 are symmetrically distributed about the axis of the roller portion, which can improve the stability and reliability of the connection.

[0098] In a preferred embodiment, the elastic member 230 includes a first diameter section 231 and a second diameter section 232. The diameter of the first diameter section 231 is smaller than that of the second diameter section 232, and the first diameter section 231 is located above the second diameter section 232. Thus, one end of the elastic member 230 can be fixed relative to the buckle, and the elastic member 230 is wrapped around the engaging section 240, thereby limiting the hanging ring 20. When the hanging ring 20 needs to be opened, the elastic member 230 can be moved to the buckle above, avoiding manipulation and preventing interference with the underlying components.

[0099] Embodiments of the present invention further provide a curtain assembly, comprising the aforementioned hanging ring 20 or the aforementioned curtain drive 30; the curtain assembly also comprising a curtain rod, on which the hanging ring 20 is mounted. By employing the aforementioned hanging ring 20 or curtain drive 30, not only can the curtain drive 30 be hung on the curtain rod, allowing the roller to act on the curtain rod and drive the curtain drive 30 to move, thereby opening and closing the curtain, but the elastic member 230 of the hanging ring 20 also limits relative movement between the first and second buckles 210, 220, thereby enhancing the stability and reliability of the connection.
