Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and relates to a track bracket with multiple hovering positions and a sunshade. Background Technology

[0002] Sunshades are widely used in existing vehicles. They consist of a curtain frame, curtain fabric, roller tube, and torsion spring. The torsion spring applies torque to the roller tube, causing the curtain fabric to tend towards a rolled-up state. Most existing sunshades cannot achieve a stopping function during the extension and retraction process, resulting in most sunshade curtains only having two states: fully extended and fully retracted. Therefore, most existing sunshades cannot meet the need for multiple stopping positions. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a track support with multiple suspension positions and a sunshade curtain.

[0004] The objective of this utility model can be achieved through the following technical solution: a track support with multiple hovering positions, comprising:

[0005] The bracket body is provided with a plurality of locking blocks arranged sequentially along a predetermined direction, and each locking block is provided with a locking groove;

[0006] The bracket body is also provided with a gear shift groove and a retraction groove. The gear shift groove and the retraction groove are located on both sides of the area where each locking block is located. The entrance of each locking groove is connected to the gear shift groove.

[0007] A guide groove is provided in the area between two adjacent locking blocks. The guide groove is connected to the outlet of the locking groove of one of the locking blocks. One end of the guide groove is connected to the retraction groove, and the other end of the guide groove extends to the area where the other locking block is located and is connected to the gear groove.

[0008] Preferably, the gear shift groove includes a plurality of first track segments and second track segments arranged alternately in a predetermined direction. Adjacent first track segments and second track segments are located between two adjacent locking grooves. The first track segment is configured as an arc-shaped track structure. The other end of the guide groove is connected to the inlet of the first track segment. The outlet of the first track segment and the inlet of the second track segment are both connected to the inlet of the locking groove, and the intersection of the three is set as a critical region.

[0009] Preferably, the locking block is provided with a stop bar portion that extends toward an adjacent locking block. The stop bar portion has a first guide surface for guiding the slide shaft to the first track segment and a second guide surface for guiding the slide shaft to the retraction groove.

[0010] Preferably, the bracket body is further provided with a first side strip, the first side strip including a plurality of arc-shaped side stops, each arc-shaped side stop being provided in correspondence with each locking block, the arc-shaped side stops being adjacent to the locking blocks, and the first trajectory segment being located between the arc-shaped side stops and the locking blocks.

[0011] Preferably, the bracket body is further provided with a second side strip, and the retraction groove is located between the second side strip and the end of the stop bar that is away from the locking block.

[0012] Preferably, the bracket body is further provided with a plurality of unlocking guide blocks arranged sequentially along a predetermined direction, each unlocking guide block corresponding to each locking block, and the unlocking guide blocks and locking blocks are arranged alternately, the unlocking guide block is close to the locking groove of the corresponding locking block, and the unlocking guide block is provided with a third guide surface for guiding the sliding shaft from the outlet of the locking groove to the guide groove.

[0013] Preferably, the locking groove is configured as an inverted V-shaped trajectory structure, and the middle region of the locking groove is configured as a locking region.

[0014] A sunshade curtain includes two track supports with multiple suspension positions, and a sunshade curtain body. The sunshade curtain body includes a curtain frame, a roller tube, and a curtain fabric. The roller tube is rotatably mounted on the curtain frame. One end of the curtain fabric is connected to the roller tube, and the other end is provided with a handle plate. The curtain frame is provided with a reset drive member connected to the roller tube. The reset drive member applies a pulling force to the handle plate through the roller tube and the curtain fabric, causing it to tend towards the curtain frame.

[0015] There are two track supports, with the support bodies of the two track supports arranged in parallel and respectively on both sides of the curtain frame. Both sides of the handle plate are provided with slider mechanisms, and the two slider mechanisms are slidably connected to the two support bodies respectively. The slider mechanisms can engage with the locking groove of any locking block to restrict the curtain from retracting.

[0016] Preferably, the slider mechanism includes a sliding seat and a swing rod. The sliding seat is fixed to the handle plate and slidably connected to the bracket body. One end of the swing rod is hinged to the sliding seat and the other end is provided with a sliding shaft. All the stop grooves, retraction grooves, locking grooves and guide grooves on the bracket body constitute a groove area. The sliding shaft is slidably connected to the groove area.

[0017] When the sliding shaft is in the stop groove, the handle plate is allowed to slide continuously in the extension direction; when the sliding shaft is in the retraction groove, the handle plate is allowed to slide continuously in the retraction direction.

[0018] When the sliding shaft slides into the locking groove through the stop groove, the sliding shaft abuts against the locking block under the pulling force of the reset drive, causing the handle plate to remain stationary relative to the bracket body. When the handle plate has a tendency to slide along the extension direction, the sliding shaft has a tendency to slide from the locking groove into the guide groove.

[0019] Preferably, when the sliding shaft is located in the guide groove, the movement trend of the handle plate determines whether the sliding shaft slides towards the stop groove or the retraction groove; wherein, when the handle plate slides along the extension direction, the sliding shaft tends towards the stop groove, and when the handle plate slides along the retraction direction, the sliding shaft tends towards the retraction groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The track bracket can provide multiple locking positions, and the handle of the sunshade can be locked with any of the locking positions, so that the curtain stops at the corresponding position.

[0022] 2. The handle can slide along the extension direction under the action of external force. When the external force is removed, the handle will retract under the action of pulling force, thus fixing it in the nearest hover position. When it is necessary to unlock, apply external force to the handle to make it slide slightly in the extension direction to unlock it. After unlocking, the handle can continue to extend under the action of external force, or automatically retract under the action of pulling force.

[0023] 3. The stop bar forms one side boundary of the guide groove. When the sliding shaft slides out of the locking groove, it is blocked by the stop bar. If the handle plate moves in the extension direction, the sliding shaft slides down to the first trajectory segment under the action of the first guide surface. If the handle plate moves in the retraction direction, the sliding shaft moves to the second guide surface of the previous stop bar and enters the retraction groove under the action of the second guide surface of the previous stop bar.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1 to 7 As shown, a track support with multiple hovering positions includes:

[0034] The bracket body 100 is provided with a plurality of locking blocks 200 arranged sequentially along a predetermined direction, and each locking block 200 is provided with a locking groove 220.

[0035] The bracket body 100 is also provided with a stop slide groove 400 and a retraction slide groove 500. The stop slide groove 400 and the retraction slide groove 500 are located on both sides of the area where each locking block 200 is located. The entrance of each locking groove 220 is connected to the stop slide groove 400.

[0036] Among them, a guide slide 600 is provided in the area between two adjacent locking blocks 200. The guide slide 600 is connected to the outlet of the locking groove 220 of one locking block 200. One end of the guide slide 600 is connected to the retraction slide 500, and the other end of the guide slide 600 extends to the area where the other locking block 200 is located and is connected to the gear slide 400.

[0037] The predetermined direction is the extension and retraction direction of the curtain. The locking groove 220 is located between the stop groove 400 and the retraction groove 500. All the stop grooves 400, locking grooves 220, retraction grooves 500 and guide grooves 600 together form a maze-like groove area.

[0038] The locking block 200 is a key structure for realizing the gear shifting function. Each locking block 200 corresponds to a hovering gear position. The locking block 200 achieves the gear shifting locking function through the locking groove 220. Preferably, the locking groove 220 is designed as a recess or notch. The sliding shaft 830 can be engaged into the locking groove 220 under the action of tension to restrict the curtain to the corresponding hovering gear position. Since the gear shifting slide 400 is connected to the entrance of each locking groove 220, the sliding shaft 830 can slide from the gear shifting slide 400 into a certain locking groove 220 to realize the gear shifting locking action. The sliding shaft 830 can slide out from the locking groove 220 and enter the guide slide 600 to realize the unlocking action. When the sliding shaft 830 enters the guide slide 600, it can slide from one end of the guide slide 600 into the retraction slide 500, and then automatically retract and reset under the action of tension. Alternatively, it can slide from the other end of the guide slide 600 into the gear shifting slide 400, allowing the curtain to continue to extend.

[0039] The working principle of the track bracket is as follows: When the curtain extends normally under external force, the sliding shaft 830 on the side of the handle plate 800 slides along the stop groove 400. After the external force is removed, the handle plate 800 retracts under the action of the reset drive (torsion spring). At this time, the sliding shaft 830 retracts into the nearest locking groove 220. Because the sliding shaft 830 is stuck in the locking groove 220, the curtain is suspended at the corresponding stop position. To unlock, simply slide the handle plate 800 along the extension direction, and the sliding shaft 830 can slide from the locking groove 220 into the guide groove 600, thus achieving the unlocking action. When the sliding shaft 830 is located in the guide groove 600, if the handle plate 800 slides in the retraction direction, the sliding shaft 830 enters the retraction groove 500, and the handle plate 800 can continue to slide in the retraction direction without obstruction; if the handle plate 800 slides in the extension direction, the sliding shaft 830 merges into the stop groove 400, and the handle plate 800 can continue to slide along the stop groove 400.

[0040] In terms of operational logic, the handle plate 800 can slide along the extension direction under the action of external force. When the external force is removed, the handle plate 800 retracts under the action of pulling force, thus fixing itself in the nearest hovering position. When unlocking is required, external force is applied to the handle plate 800 to make it slide slightly in the extension direction, which can unlock it. After unlocking, the handle plate 800 can continue to extend under the action of external force, or automatically retract under the action of pulling force.

[0041] The core principle of this track support is to use a maze structure to provide a specific gear path, use gear slots to achieve gear hovering, use gear slides 400 to provide a path for gear selection, and use guide slides 600 to provide a path for reset or continued extension. It strictly controls the path logic of the slide shaft 830 moving from one locking slot 220 to another, thereby ensuring the smoothness, accuracy and safety of multiple gear switching.

[0042] Based on the above embodiments, the gear shift groove 400 includes a plurality of first track segments 410 and second track segments 420 arranged alternately in a predetermined direction. Adjacent first track segments 410 and second track segments 420 are located between two adjacent locking grooves 220. The first track segment 410 is configured as an arc-shaped track structure. The other end of the guide groove 600 is connected to the inlet of the first track segment 410. The outlet of the first track segment 410 and the inlet of the second track segment 420 are both connected to the inlet of the locking groove 220, and the intersection of the three is set as a critical region 430.

[0043] The first track segment 410 can control the angle and posture of the sliding shaft 830 through its own track shape, and the shape of the first track segment 410 can guide the sliding shaft 830 into the locking groove 220. Specifically, the critical position and the entrance of the locking groove 220 are set exactly along the curtain extension direction. The second track segment 420 is set as a straight groove structure extending along the curtain extension direction, and the exit of the first track segment 410 is connected to the entrance of the second track segment 420. When the sliding shaft 830 slides into the critical region 430 or the second track segment 420 after passing through the first track segment 410, the sliding shaft 830 is exactly aligned with the entrance of the locking groove 220 in the curtain extension direction. When the handle plate 800 retracts, the sliding shaft 830 can pass through the critical region 430 and enter the locking groove 220.

[0044] Through the above design, the sliding shaft 830 can only slide from the first track segment 410 into the second track segment 420. When the sliding shaft 830 is in the critical region 430 or the second track segment 420, it cannot retreat back into the first track segment 410 and can only enter the locking groove 220, thereby achieving the effect of automatic locking after releasing the hand.

[0045] like Figures 1 to 5 As shown, based on the above embodiment, the locking block 200 is provided with a stop bar portion 210, which extends to an adjacent locking block 200. The stop bar portion 210 has a first guide surface 211 for guiding the slide shaft 830 to the first trajectory segment 410 and a second guide surface 212 for guiding the slide shaft 830 to the retraction groove 500.

[0046] The baffle 210 forms one side boundary of the guide groove 600. When the slide shaft 830 slides out of the outlet of the locking groove 220, it is blocked by the baffle 210. If the handle plate 800 moves in the extension direction, the slide shaft 830 slides down to the first trajectory segment 410 under the action of the first guide surface 211. If the handle plate 800 moves in the retraction direction, the slide shaft 830 moves to the second guide surface 212 of the upper baffle 210, and the slide shaft 830 enters the retraction groove 500 under the action of the second guide surface 212 of the upper baffle 210.

[0047] Based on the above embodiments, the bracket body 100 is further provided with a first side strip 110. The first side strip 110 includes a plurality of arc-shaped side stops 111. Each arc-shaped side stop 111 is correspondingly provided with each locking block 200. The arc-shaped side stops 111 are adjacent to the locking blocks 200. The first trajectory segment 410 is located between the arc-shaped side stops 111 and the locking blocks 200.

[0048] Based on the above embodiments, the bracket body 100 is also provided with a second side strip 120, and the retraction groove 500 is located between the second side strip 120 and the end of the stop bar 210 away from the locking block 200.

[0049] Based on the above embodiments, the bracket body 100 is further provided with a plurality of unlocking guide blocks 300 arranged sequentially along a predetermined direction. Each unlocking guide block 300 is corresponding to each locking block 200, and each unlocking guide block 300 and each locking block 200 are arranged alternately. The unlocking guide block 300 is close to the locking groove 220 of the corresponding locking block 200. The unlocking guide block 300 is provided with a third guide surface 310 for guiding the sliding shaft 830 from the outlet of the locking groove 220 to the guide groove 600.

[0050] The unlocking guide block 300 can be regarded as a dedicated unlocking structure equipped with the locking groove 220. The third guide surface 310 is designed as a sloping structure. When the handle plate 800 moves along the extension direction, the sliding shaft 830 deflects under the action of the third guide surface 310 and slides into the guide groove 600, thereby achieving the purpose of unlocking by lightly pulling the handle plate 800.

[0051] Based on the above implementation, the locking groove 220 is configured as an inverted V-shaped trajectory structure, and the middle area of ​​the locking groove 220 is configured as a locking area.

[0052] like Figures 1 to 7As shown, a sunshade curtain includes two track supports with multiple suspension positions, and a sunshade curtain body. The sunshade curtain body includes a curtain frame 700, a roller tube, and a curtain fabric. The roller tube is rotatably mounted on the curtain frame 700. One end of the curtain fabric is connected to the roller tube and the other end is provided with a handle plate 800. The curtain frame 700 is provided with a reset drive member connected to the roller tube. The reset drive member applies a pulling force to the handle plate 800 through the roller tube and the curtain fabric, causing it to tend towards the curtain frame 700.

[0053] There are two track supports, with the support bodies 100 of the two track supports arranged in parallel and respectively on both sides of the curtain frame 700. Both sides of the handle plate 800 are provided with slider mechanisms, and the two slider mechanisms are slidably connected to the two support bodies 100 respectively. The slider mechanisms can engage with the locking groove 220 of any locking block 200 to limit the retraction of the curtain.

[0054] The connection structure between the reset drive, the roller tube, the curtain fabric, and the handle plate 800 is prior art and will not be described in detail here. Among them, the reset drive is a very critical component, preferably a torsion spring. The reset drive can continuously apply torque to make the roller tube rotate. This torque is converted into a constant pulling force on the handle plate 800, which is always pointing in the direction of the curtain frame 700 (i.e., the retraction direction), through the winding of the curtain fabric. Both sides of the handle plate 800 are provided with slider mechanisms. Through the slider mechanisms and the labyrinth-shaped sliding groove area on the bracket body 100, multi-position hovering and unlocking functions can be realized.

[0055] Based on the above embodiment, the slider mechanism includes a sliding seat 810 and a swing rod 820. The sliding seat 810 is fixed to the handle plate 800 and slidably connected to the bracket body 100. One end of the swing rod 820 is hinged to the sliding seat 810, and the other end is provided with a sliding shaft 830. All the stop slide grooves 400, retraction slide grooves 500, locking grooves 220, and guide slide grooves 600 on the bracket body 100 constitute a slide groove area. The sliding shaft 830 is slidably connected to the slide groove area. When the sliding shaft 830 is located in the stop slide groove 400, the handle plate... 800 is allowed to slide continuously in the extension direction; when the slide shaft 830 is located in the retraction groove 500, the handle plate 800 is allowed to slide continuously in the retraction direction; when the slide shaft 830 slides into the locking groove 220 through the stop groove 400, the slide shaft 830 is in contact with the locking block 200 under the pulling force of the reset drive, causing the handle plate 800 to remain stationary relative to the bracket body 100, and when the handle plate 800 has a tendency to slide in the extension direction, the slide shaft 830 has a tendency to slide from the locking groove 220 into the guide groove 600.

[0056] The handle plate 800 is slidably connected to the bracket body 100 via the sliding seat 810. The swing rod 820 can swing around the hinge point between itself and the sliding seat 810, thereby driving the sliding shaft 830 to swing around the hinge point, so that the sliding shaft 830 can slide freely in the labyrinthine sliding groove area.

[0057] Based on the above embodiments, when the sliding shaft 830 is located in the guide groove 600, the movement trend of the handle plate 800 determines whether the sliding shaft 830 slides towards the stop groove 400 or the retraction groove 500; wherein, when the handle plate 800 slides along the extension direction, the sliding shaft 830 tends to move towards the stop groove 400, and when the handle plate 800 slides along the retraction direction, the sliding shaft 830 tends to move towards the retraction groove 500.

[0058] The working principle of this sunshade is as follows: the handle plate 800 is subjected to a constant pulling force that retracts towards the curtain frame 700, with the direction of curtain extension being the downward direction and the direction of curtain retraction being the upward direction. When the user pulls the handle plate 800 downward, the sliding shaft 830 slides within the stop groove 400, and the sliding shaft 830 swings along the trajectory of the stop groove 400. When the sliding shaft 830 slides from one locking groove 220 to the next locking groove 220, it has completely passed through the first trajectory segment 410 and the second trajectory segment 420.

[0059] During this extension process, when the user releases the handle plate 800, the handle plate 800 automatically moves upward under the pulling force. The sliding shaft 830 located in the gear shift groove 400 gradually slides towards the nearest upper locking groove 220. Specifically, the sliding shaft 830 slides upward into the nearest upper critical region 430. The sliding shaft 830 in the critical region 430 is located directly below the locking groove 220. Under the pulling force, the sliding shaft 830 can interact with the lower surface of the locking block 200 to swing to a suitable angle. Then, under the pulling force, it automatically slides into the locking groove 220 and is locked in the locking area. At this time, the handle plate 800 (curtain) is suspended in the suspended position, thereby realizing the gear shift locking action.

[0060] When unlocking is required, the user gently pulls the handle plate 800, causing it to slide downwards a short distance. The sliding shaft 830 swings under the action of the third guide surface 310 of the unlocking guide block 300, causing it to leave the locking groove 220 and slide into the guide groove 600. If the user releases the handle plate 800, the sliding shaft 830 moves upwards, swinging under the action of the second guide surface 212 of the previous stop bar 210 and gradually sliding into the retraction groove 500, allowing the handle plate 800 to move continuously upwards under pulling force. If the user pulls the handle plate 800 downwards, the sliding shaft 830 slides along the first guide surface 211 of the stop bar 210 into the first trajectory segment 410, allowing the handle plate 800 to slide continuously downwards under the user's pull.

[0061] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0062] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0063] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0064] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

7. A track support with multiple hovering positions as described in claim 1, characterized in that: The locking groove (220) is configured as an inverted V-shaped trajectory structure, and the middle area of ​​the locking groove (220) is configured as a locking area.

8. A sunshade curtain, characterized in that, The device includes two track supports with multiple suspension positions as described in any one of claims 1 to 7, and also includes a sunshade body, the sunshade body including a curtain frame (700), a roller tube and a curtain fabric, the roller tube being rotatably mounted on the curtain frame (700), one end of the curtain fabric being connected to the roller tube and the other end being provided with a handle plate (800), the curtain frame (700) being provided with a reset drive member connected to the roller tube, the reset drive member applying a pulling force to the handle plate (800) through the roller tube and the curtain fabric to make it tend toward the curtain frame (700); There are two track supports. The support bodies (100) of the two track supports are arranged in parallel and are respectively located on both sides of the curtain frame (700). Both sides of the handle plate (800) are provided with slider mechanisms. The two slider mechanisms are slidably connected to the two support bodies (100) respectively. The slider mechanisms can engage with the locking groove (220) of any locking block (200) to restrict the curtain fabric from retracting.

9. A sunshade curtain as described in claim 8, characterized in that: The slider mechanism includes a sliding seat (810) and a swing rod (820). The sliding seat (810) is fixed to the handle plate (800) and slidably connected to the bracket body (100). One end of the swing rod (820) is hinged to the sliding seat (810) and the other end is provided with a sliding shaft (830). All the stop grooves (400), retraction grooves (500), locking grooves (220) and guide grooves (600) on the bracket body (100) constitute a groove area. The sliding shaft (830) is slidably connected to the groove area.
