The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent.

Referring to fig. 1 to 5, a sunshade device according to an embodiment of the application will be described. The sunshade device comprises a frame 1, a sunshade 2 and a driving mechanism 3.

Wherein the frame 1 comprises a box 11 and a box cover 12. The case 11 is provided with an open receiving groove 111, and the case cover 12 is rotatably connected to the case 11 by a hinge 16, in other words, when the case cover 12 is rotated with respect to the case 11, the projected position of the center of gravity of the case cover 12 projected to the receiving groove 111 in the vertical direction is changed, and the case cover 12 is used to cover the notch of the receiving groove 111. In addition, the sunshade umbrella 2 is rotatably connected to the case 11, so that the sunshade umbrella 2 can be stored in the storage groove 111 as shown in fig. 1, or can stand up away from the storage groove 111 as shown in fig. 3, and for convenience of description, a position of the sunshade umbrella 2 stored in the storage groove 111 shown in fig. 1 is defined as a first position of the sunshade umbrella 2, and a position of the sunshade umbrella 2 away from the storage groove 111 in fig. 3 is defined as a second position of the sunshade umbrella 2. Specifically, referring to fig. 5, a rotating shaft 15 is fixed on the case 11, and the sunshade 2 is sleeved on the outer wall of the rotating shaft 15 and can rotate around the axis of the rotating shaft 15. Wherein the driving mechanism 3 is connected with the case 11 and the sunshade 2, and the driving mechanism 3 is used as power for driving the sunshade 2 to rotate relative to the case 11. Fig. 4 shows the sunshade 2 in an unfolded state, in which the sunshade 2 can be used for sunshade.

Further, after the cover 12 covers the accommodating groove 111, the cover 12 may be attracted to the case 11 by a magnet structure, and when the driving mechanism 3 drives the sunshade umbrella 2 to rotate from the first position shown in fig. 1 to the second position shown in fig. 3, the sunshade umbrella 2 can drive the cover 12 to separate from the magnetic force on the case 11 and gradually open; when the driving mechanism 3 drives the sunshade umbrella 2 to fall back to the first position shown in fig. 1 again in the second position shown in fig. 3, the sunshade umbrella 2 drives the cover 12 to automatically cover toward the notch of the storage groove 111 through the linkage mechanism 4.

Referring to fig. 5, in one embodiment, the linkage mechanism 4 includes a linkage rope 41 (indicated by a chain line in fig. 5 as a linkage rope 41), one end of the linkage rope 41 is connected to the sunshade 2, and the other end of the linkage rope 41 is connected to the cover 12. At this time, when the driving mechanism 3 drives the sunshade 2 to fall back to the first position shown in fig. 1 again in the second position shown in fig. 3, the sunshade 2 can automatically cover the storage groove 111 by pulling the link rope 41, thereby realizing the function of the cover 12.

Referring to fig. 5, in the embodiment of the present application, the linkage mechanism 4 includes a linkage rope 41 and a rope sheave 42, and the rope sheave 42 is sleeved on the rotating shaft 15 and fixed on the base 21 of the sunshade 2, so that the rope sheave 42 can also rotate around the axis of the rotating shaft 15. One end of the link rope 41 is fixed to the sheave 42 and wound around a sheave surface 421 of the sheave 42, and the other end of the link rope 41 is also fixed to the case cover 12. When the driving mechanism 3 drives the sunshade 2 to fall back to the first position shown in fig. 1 again in the second position shown in fig. 3, the link rope 41 is gradually wound around the sheave 42, and the cover 12 is pulled by the link rope 41 due to the tension of the link rope 41 on the cover 12, so that the cover 12 covers the notch of the receiving groove 111. When the driving mechanism 3 drives the sunshade 2 to rotate from the first position shown in fig. 1 to the second position shown in fig. 3, the linkage rope 41 gradually winds out of the rope sheave 42, so that the sunshade 2 can smoothly push up the cover 12, and when the sunshade 2 pushes up the cover 12 to a certain position, the cover 12 will receive its own weight to gradually open the storage groove 111.

Specifically, referring to fig. 3 and 5 together, a protruding block 121 is disposed on the inner side of the case cover 12, a connecting portion 122 and a limiting structure 123 are disposed on the protruding block 121, the connecting portion 122 is used for fixing one end of the connecting rope 41, and the limiting structure 123 is used for limiting the extending path of the connecting rope 41 to prevent the connecting rope 41 from separating from the protruding block 121. In other words, when one end of the link rope 41 is gradually wound out from the sheave 42, the protruding block 121 on the cover 12 that is being gradually opened can urge the other end of the link rope 41 to be gradually pulled out in the direction in which the cover 12 is opened, so that the link rope 41 can be in a tensioned state.

More specifically, referring to fig. 3 and 5 together, the protruding block 121 has a supporting surface 1211 away from the cover 12, the supporting surface 1211 is a part of an arc surface with a center falling on the rotation axis of the cover 12 (i.e. the rotation axis of the hinge 16), and the radius from the supporting surface 1211 to the rotation axis of the cover 12 is equal to or slightly greater than the radius from the wheel surface 421 to the rotation axis of the sunshade 2 (i.e. the axis of the rotation shaft 15) that rotates relative to the frame 1. In this way, when one end of the link rope 41 is wound from the sheave 42 by the distance D1 in a unit time, the protruding block 121 on the cover 12 that is gradually opening can drive the other end of the link rope 41 to be pulled out by a distance equal to or slightly greater than D1 in a unit time in the direction in which the cover 12 is opened, so that the link rope 41 can be also in a tensioned state when the cover 12 is opened. In addition, the connecting portion 122 is disposed on the supporting surface 1211 and is close to the inner side surface of the case cover 12, and the limiting structure 123 is disposed around the supporting surface 1211 and extends in the same direction as the supporting surface 1211.

In this embodiment, referring to fig. 5, the limiting structure 123 is preferably a limiting protrusion disposed on two sides of the supporting surface 1211, a limiting groove 124 is formed between the limiting protrusions on two sides, the connecting portion 122 is disposed in the extending direction of the limiting groove 124, and a connecting hole 1221 is disposed on the connecting portion 122, one end of the connecting hole 1221 is communicated with the limiting groove 124 and gradually extends to the inner side surface of the case cover 12, and one end of the linkage rope 41 is inserted and fixed in the connecting hole 1221.

Referring to fig. 5, the central axis of the rotating shaft 15 and the rotation axis of the hinge 16 are not in the same line, so that the posture of the linkage rope 41 will be changed during the retraction process, which may cause a problem that the linkage rope 41 is blocked on other components. In this regard, the frame 1 of the present embodiment further includes a limiting post 17 connected to the case 11, where a central axis of the limiting post 17 is vertically disposed, in other words, a central axis of the limiting post 17 is perpendicular to the rotation axes of the rotating shaft 15 and the hinge 16, and the limiting post 17 is used for tensioning the linkage rope 41, and when the linkage rope 41 is in a process of winding and unwinding, the linkage rope 41 can be abutted on the limiting surface 171 outside the limiting post 17. In addition, the limiting post 17 can also limit the posture of the linkage rope 41, specifically, due to the fact that the limiting post 17 is arranged, one part of the linkage rope 41 can linearly extend to the wheel surface 421, the other part of the linkage rope 41 can linearly extend to the connecting part 122, the fact that the posture of the linkage rope 41 is hardly changed in the winding and unwinding process is guaranteed, and the problem that the linkage rope 41 is blocked is avoided. In addition, the limiting post 17 is also rotatably connected to the case 11, and when the linkage rope 41 is retracted and released, the limiting surface 171 on the outer side of the limiting post 17 receives the static friction force exerted by the linkage rope 41 and then rotates relative to the case 11, so that the friction force between the linkage rope 41 and the limiting post 17 can be greatly reduced.

Referring to fig. 5, the frame 1 of the present embodiment further includes a limit baffle 18 fixed on the case 11, where the limit baffle 18 faces the limit surface 171 and is spaced from the limit post 17, so that a limit channel 181 is formed between the limit post 17 and the limit baffle 18, the limit channel 181 allows the link rope 41 to pass through, and the limit baffle 18 can prevent the link rope 41 from moving in a direction away from the limit surface 171, at this time, further ensure the reliability of the link rope 41 during the winding and unwinding process, and further avoid the problem that the link rope 41 and other components are blocked.

Here, the above-mentioned linkage structure that can link the opening or closing of the cover 12 when the sunshade 2 is switched between the first position and the second position with respect to the frame 1 is not limited to the sunshade field, and can also be used for other members to be lifted to link the opening or closing of the cover 12 when moving on the frame 1. Specifically, in other embodiments, the to-be-lifted member is connected to the frame 1 and is connected to the driving mechanism 3 through a connecting mechanism, and when the driving mechanism 3 drives the connecting mechanism to move, the driving mechanism 3 can drive the to-be-lifted member to switch between a position accommodated in the accommodating groove 111 and a position located outside the accommodating groove 111. In this embodiment, the connecting mechanism is a base 21, and the member to be lifted is an umbrella 22.

Referring to fig. 1 and 3, the frame 1 further includes a connecting rod 13 and a case 14. The connecting rod 13 is fixed in the bottom of box 11, and connecting rod 13 is used for connecting the original dead lever in car top position, makes frame 1 wholly can stabilize at the top of car, and when sun shade 2 was in the state of expanding, sun shade 2 can cover the front windshield and the rear windshield of car. Of course, the frame 1 may not include the connecting rod 13, and the connecting rod 13 may be purchased externally by the user as an existing component. And a housing cover 14 is fixed in front of the housing 11, the housing cover 14 being used to cover the driving mechanism 3, so that external factors can be prevented from damaging the driving mechanism 3 when the sunshade 2 is received in the receiving groove 111. When the housing 14 is removed, maintenance of the drive mechanism 3 is facilitated, and manual operation of the drive mechanism 3 is also facilitated.

Referring to fig. 3, 6 and 7, the driving mechanism 3 of the present embodiment mainly includes a switching block 31, a driving module 32, a push rod 33 and a guide seat 34.

The driving module 32 is mounted on the adapter block 31 and connected to the push rod 33, and the driving module 32 can drive the push rod 33 to approach or separate from the adapter block 31. Secondly, the adapter block 31 is hinged to the case 11, one end of the push rod 33 far away from the adapter block 31 is rotationally connected with the sunshade umbrella 2, and the connection part of the push rod 33 and the sunshade umbrella 2 is spaced from the rotating shaft 15, when the push rod 33 is driven by the driving module 32 to approach or separate from the adapter block 31, the push rod 33 can drive the sunshade umbrella 2 to rotate around the axis of the rotating shaft 15, the guide seat 34 is connected with the driving module 32 and is provided with a guide hole 341, the extending direction of the guide hole 341 is the same as the length direction of the push rod 33, the push rod 33 is inserted into the guide hole 341 and can move along the axis of the guide hole 341, and the guide seat 34 is used for improving the movement precision of the push rod 33. Specifically, referring to fig. 5 and fig. 6 together, the push rod 33 is provided with a plug hole 331, a rotation pin 35 is inserted into the plug hole 331, the rotation pin 35 is fixed at the bottom end of the sunshade 2, and the push rod 33 can rotate around the rotation pin 35. The torque required by the driving module 32 can be reduced by switching the sunshade 2 between the first position and the second position by means of reciprocating the push rod 33.

Referring to fig. 6 and 7 together, the driving module 32 specifically includes a driver 321, a screw 322, a nut block 323 and a limiting plate 324. The driver 321 is connected to the adapter block 31 and the guide seat 34, the screw 322 is connected to an output end of the driver 321 and is accommodated in the guide hole 341, the nut block 323 is screwed to the screw 322, and the push rod 33 is fixed on the nut block 323. In operation, the driver 321 drives the screw 322 to rotate, and the screw 322 drives the nut block 323 and the push rod 33 to reciprocate along the length direction of the screw 322 to approach or separate from the adapter block 31. The limiting piece 324 is fixed at one end of the screw 322 far away from the driver 321, so as to limit the nut block 323 to separate from the screw 322, and the limiting piece 324 can also be used for limiting the position of the sunshade umbrella 2 in the second position, i.e. when the nut block 323 abuts against the limiting piece 324, the sunshade umbrella 2 reaches the second position, and further, no additional limiting piece is required to limit the position of the sunshade umbrella 2 when reaching the second position.

Referring again to fig. 7, one end of the push rod 33 facing the driver 321 is provided with a avoiding hole 332, the depth direction of the avoiding hole 332 is the same as the length direction of the screw 322, and a portion of the screw 322, a portion of the nut block 323, and the limiting piece 324 are all accommodated in the avoiding hole 332. In addition, the nut block 323 specifically includes a first body 3231 and a second body 3232 that are connected, where a connection surface 32311 is disposed on a side of the first body 3231 facing away from the driver 321, the second body 3232 is connected to the connection surface 32311, the push rod 33 abuts against the connection surface 32311 and is fixedly connected to the first body 3231, and the second body 3232 is accommodated in the avoidance hole 332, and both the first body 3231 and the second body 3232 may be provided with threaded holes that are screwed with the screw 322, and the above-mentioned limiting piece 324 may limit the second body 3232 from being separated from the screw 322.

In this embodiment, referring to fig. 6 and fig. 7 together, the driver 321 specifically includes a motor 3211 and a speed reducer 3212, an output shaft of the motor 3211 is connected to an input end of the speed reducer 3212, the speed reducer 3212 is connected to one end of the screw 322, and the speed reducer 3212 is fixed on the adapter block 31. In operation, the power of the motor 3211 may be transmitted to the screw 322 via the reducer 3212, thereby driving the screw 322 to perform a rotational motion.

Referring to fig. 6 and 7, the driving mechanism 3 further includes a knob 36, and the knob 36 is fixed at one end of the screw 322, and when the knob 36 is manually turned, the screw 322 is driven to rotate.

Referring to fig. 3, the driving mechanism 3 further includes a power storage module (not shown) fixed to the housing 11 and configured to provide power to the driver 321. The power storage module may be a lithium battery power supply or a solar module, etc.

In summary, the push rod 33 is driven by the screw rod 322 to perform telescopic movement, so that not only the torque required by the motor 3211 can be reduced, the volume of the motor 3211 is reduced, and the cost of the motor 3211 is reduced, but also the push rod 33 cannot spontaneously move along the axial direction of the screw rod 322, namely, the sunshade umbrella 2 at the second position cannot spontaneously fall back to the first position due to gravity, so that the motor 3211 can stop outputting power when the sunshade umbrella 2 is at the second position, at the moment, the matching relationship between the screw rod 322 and the nut block 323 can form a reverse self-locking structure, and the sunshade umbrella 2 can still be reliably fixed at the second position on the premise that the motor 3211 does not have power output. In addition, in this case, by combining the design of the knob 36, when the electric quantity of the electric storage module is insufficient or the motor 3211 fails, the switching between the first position and the second position of the sunshade umbrella 2 can be manually controlled by the knob 36, and the reliable fixing of the sunshade umbrella 2 at the second position can be ensured.

The detailed structure of the sunshade 2 will be described in detail with reference to the accompanying drawings.

Referring to fig. 8 to 12, the sunshade 2 includes a base 21, a body 22 and a driving unit 23. Wherein the base 21 rotates relative to the frame 1 about the rotation axis 15, the umbrella 22 is rotatably connected to the base 21, and the driving unit 23 is fixed on the base 21 and is used for driving the umbrella 22 to rotate relative to the base 21. The axis of rotation of the umbrella 22 relative to the base 21 and the axis of rotation of the base 21 relative to the frame 1 (i.e., the axis of the rotary shaft 15) are perpendicular to each other.

Referring to fig. 4 and fig. 8-12, the umbrella 22 further includes a sunshade 221, a telescopic assembly 222, and a rib assembly 223. Wherein, the rib assembly 223 is connected with the sunshade cloth 221 and has an unfolding state for unfolding the sunshade cloth 221 and a folding state for folding the sunshade cloth 221. In addition, the telescopic component 222 is connected with the rib component 223 and is rotatably connected with the base 21, and the driving unit 23 is connected with the telescopic component 222 and can drive the telescopic component 222 to rotate relative to the base 21, so as to drive the rib component 223, the sun-shading cloth 221 and the telescopic component 222 to synchronously rotate. The drive unit 23 is also capable of driving the telescoping assembly 222 away from or towards the base 21 to place the rib assembly 223 in an extended or collapsed state.

More specifically, referring to fig. 8-12, the driving unit 23 includes a fixing base 231, a driving member 232, a rotating rod 233 and a blocking member 234. The fixing seat 231 is fixed on the base 21, the driving member 232 is fixed on the fixing seat 231, the driving member 232 is preferably a motor, the rotating rod 233 is preferably a screw rod with external threads, one end of the rotating rod 233 is connected with an output shaft of the driving member 232, the rotating rod 233 is rotatably connected with the fixing seat 231 through a bearing, when the driving member 232 works, the rotating rod 233 can be driven to rotate, the telescopic assembly 222 is in threaded connection with the rotating rod 233, and when the rotating rod 233 rotates, the telescopic assembly 222 can be driven to approach or separate from the base 21. The blocking member 234 is fixed at the top end of the rotating rod 233, the blocking member 234 is used for limiting the telescopic assembly 222 to separate from the rotating rod 233, and when the telescopic assembly 222 abuts against the blocking member 234, the telescopic assembly 222 cannot move along the axial direction of the rotating rod 233, and at this time, the rotating rod 233 can drive the telescopic assembly 222 to rotate synchronously.

Further, referring to fig. 8-12 again, the telescopic assembly 222 includes a nut seat 2221 and a telescopic rod 2222. The nut seat 2221 is screwed to the rotating rod 233, and the telescopic rod 2222 is fixed on the nut seat 2221, and rotation of the rotating rod 233 can drive the nut seat 2221 and the telescopic rod 2222 to approach or depart from the base 21 together. The blocking member 234 is disposed on a side of the nut seat 2221 facing away from the base 21, and the blocking member 234 is used to limit the nut seat 2221 from being separated from the rotating rod 233.

Further, referring to fig. 11 and 12, the nut seat 2221 includes a first body 22211 and a second body 22212. The first body 22211 has a connection end surface 222111 on a side facing the telescopic rod 2222, and the second body 22212 is connected to the connection end surface 222111. In addition, an end of the telescopic rod 2222 facing the nut seat 2221 is provided with a relief passage 22221, the extending direction of the relief passage 22221 is the same as the length direction of the rotation rod 233, the second main body 22212, a portion of the rotation rod 233 and the stopper 234 are all accommodated in the relief passage 22221, and the telescopic rod 2222 is fixedly connected to the first main body 22211 by abutting against the connection end face 222111. A screw hole screwed with the rotation lever 233 may be provided in either the first body 22211 or the second body 22212.

In more detail, referring again to fig. 8-12, the rib assembly 223 includes a rotating base 2231, a lower mounting base 2232, an upper mounting base 2233, a plurality of driving rods 2234, and a plurality of link assemblies 2235.

The rotating seat 2231 is rotatably connected to the fixed seat 231, and the fixed seat 231 is fixed to the base 21, so that the rotating seat 2231 is rotatably connected to the base 21. Specifically, two bearings 2236 are sleeved on the fixed seat 231, the inner diameter of the bearing 2236 is fixed on the fixed seat 231, and the outer diameter of the bearing 2236 is fixed on the rotating seat 2231, so that the rotating seat 2231 can rotate relative to the fixed seat 231, and meanwhile, since the rotating seat 2231 is connected to the telescopic rod 2222 through each connecting rod assembly 2235, the rotation of the telescopic rod 2222 drives the rotating seat 2231 to rotate through each connecting rod assembly 2235, and further drives the sun-shading cloth 221 to rotate. In other words, when the telescopic link 2222 rotates in synchronization with the rotating link 233, the rotating base 2231, the lower mounting base 2232, the upper mounting base 2233, the plurality of driving links 2234, the plurality of link assemblies 2235 and the sunshade cloth 221 all rotate in synchronization with the telescopic link 2222.

In addition, the rotation seat 2231 is provided with a middle hole 22311, the middle hole 22311 extends along the movement direction of the telescopic rod 2222, and the telescopic rod 2222 is inserted into the middle hole 22311 and can slide along the wall of the middle hole 22311. In other words, the swivel base 2231 functions to guide the telescoping rod 2222 in addition to the link assembly 2235.

The lower mounting seat 2232 is fixed on the telescopic rod 2222 through a shaft pin 2237, and the lower mounting seat 2232 also plays a role of connecting the link assembly 2235, when the telescopic rod 2222 approaches or departs from the base 21, the lower mounting seat 2232 can drive the link assembly 2235 to open or close inwards, so that the sun-shading cloth 221 connected on the link assembly 2235 can be opened or closed.

The upper mounting seat 2233 also serves to connect the link assembly 2235, and the upper mounting seat 2233 is located on a side of the lower mounting seat 2232 facing away from the base 21, and a connection line with the lower mounting seat 2232 is the same as a movement direction of the telescopic rod 2222. Specifically, when the upper mount 2233 and the lower mount 2232 are close to each other, the link assembly 2235 is distracted; when the upper and lower mounts 2233 and 2232 are spaced apart from each other, the link assembly 2235 is collapsed. In addition, when the upper and lower mounting bases 2233 and 2232 are moved closer to each other, the top of the telescopic rod 2222 is inserted into the positioning hole 22331 on the upper mounting base 2233, thereby ensuring that the upper and lower mounting bases 2233 and 2232 have better relative positional accuracy.

One end of the driving rod 2234 is hinged to the lower mounting seat 2232, and the other end of the driving rod 2234 is hinged to one of the link assemblies 2235, wherein the driving rod 2234 can drive the link assemblies 2235 to be unfolded or folded inwards when the lower mounting seat 2232 approaches or moves away from the base 21.

Among other things, the link assembly 2235 includes a first link 22351, a second link 22352, a third link 22353, and a fourth link 22354. One end of the first link 22351 is hinged to the rotating seat 2231, the other end of the first link 22351 is hinged to the second link 22352, one end of the second link 22352, which is far away from the first link 22351, is connected to the sunshade cloth 221, one end of the third link 22353 is hinged to the upper mounting seat 2233, the other end of the third link 22353 is hinged to the fourth link 22354, and one end of the fourth link 22354, which is far away from the third link 22353, is hinged to the middle of the second link 22352. The driving rod 2234 is hinged to one of the first links 22351.

The specific working principle of the sunshade umbrella 2 is as follows: when the sunshade umbrella 2 is at the second position, the driving member 232 drives the rotating rod 233 to rotate relative to the base 21, at this time, the telescopic rod 2222 is gradually close to the base 21 (i.e. moves downwards) under the driving of the nut seat 2221, meanwhile, at this time, since the lower mounting seat 2232 is gradually close to the base 21 along with the telescopic rod 2222, the driving rod 2234 gradually and outwardly expands the first link 22351, the second link 22352, the third link 22353 and the fourth link 22354 are also gradually and outwardly expanded under the driving of the first link 22351, at the same time, the upper mounting seat 2233 is also gradually close to the lower mounting seat 2232 under the driving of the third links 22353, and after the sunshade cloth 221 is completely expanded, the top of the telescopic rod 2222 is inserted into the positioning hole 22331 of the upper mounting seat 2233, so as to ensure a good relative position between the umbrella rib assembly 223 and the telescopic rod 2222. When the umbrella is required to be folded, the driving member 232 drives the rotating rod 233 to rotate reversely, at this time, the telescopic rod 2222 is driven by the nut seat 2221 to be gradually far away from the base 21 (i.e. move upwards), at the same time, the lower mounting seat 2232 is gradually far away from the base 21 along with the telescopic rod 2222, so that the driving rod 2234 is gradually folded inwards, the driving rod 2234 pulls the first connecting rod 22351 to be gradually folded inwards, the first connecting rod 22351 drives the second connecting rod 22352, the third connecting rod 22353 and the fourth connecting rod 22354 to be gradually folded inwards, at the same time, the upper mounting seat 2233 is also driven by the third connecting rods 22353 to be gradually far away from the lower mounting seat 2232, and when the nut seat 2221 is propped against the blocking member 234, the sun-shading cloth 221 can be folded.

Referring to fig. 1 and 3 together, after the sunshade 2 rotates to the first position shown in fig. 1 and stored in the storage groove 111 in the second position shown in fig. 3, since the sunshade 221 is a soft member, the sunshade 221 is partially exposed out of the storage groove 111, and the cover 12 covers the storage groove 111, but the driving member 232 can drive the rotating rod 233 to rotate, the nut seat 2221 cannot keep away from the base 21 due to the blocking member 234, and the nut seat 2221 and the telescopic rod 2222 rotate synchronously along with the rotation of the rotating rod 233, and since the telescopic rod 2222 is connected with the sunshade 221 through the rib assembly 223, the rib assembly 223 and the sunshade 221 also rotate synchronously along with the rotation of the telescopic rod 2222, and finally the sunshade 221 is driven to be completely stored in the storage groove 111 through the gap between the cover 12 and the box 11.

As is clear from the upper section, after the umbrella body 22 is rotated relative to the base 21 by the driving unit 23, the sun-shading cloth 221 on the umbrella body 22 can be completely accommodated in the accommodating groove 111, however, since it is not known how much the umbrella body 22 is rotated in the accommodating groove 111, the posture of the umbrella body 22 in the accommodating groove 111 is uncertain, when the umbrella is reopened next time, the sun-shading cloth 2 is rotated from the first position accommodated in the accommodating groove 111 to the second position by the driving of the driving mechanism 3, since the specific posture of the umbrella body 22 relative to the frame 1 is not known when the umbrella body 22 is in the first position, the posture of the sun-shading cloth 221 on the umbrella body 22 relative to the frame 1 is also uncertain when the umbrella body 22 is unfolded in the second position, and thus the posture of the sun-shading cloth 221 relative to the automobile is uncertain when the sun-shading cloth 221 is unfolded, however, for some sun-shading fields, the shape of the sun-shading cloth 221 is directional, as shown in fig. 4, and the length of the sun-shading cloth 221 is significantly longer than the width, however, the shape of the sun-shading cloth 221 is designed to be different from the sun-shading cloth 21 relative to the frame 1 when the sun-shading cloth 221 is not shown in the outer shape of the sun-shading cloth 21, and the sun-shading cloth 221 is not folded from the outer shape of the frame 1, and the sun-shading cloth is not shown separately, and the posture of the sun-shading cloth is not shown in the outer shape.

Referring to fig. 11-16 together, in order to correct the posture of the umbrella 22 relative to the frame 1, the sunshade device of the present application further comprises a correcting structure 5, where the correcting structure 5 includes a guide block 51 and a collision portion 52 disposed on a circumferential side wall of the umbrella 22, the guide block 51 is preferably a part of the frame 1, specifically, the guide block 51 is fixed on the case 11, and the guide block 51 has at least one guide surface 511, when the sunshade umbrella 2 is driven by the driving mechanism 3 to move from the first position to the second position, the collision portion 52 contacts with the guide surface 511, and forces the umbrella 22 to rotate relative to the base 21 under the guidance of the guide surface 511, and when the umbrella 22 rotates to the second position, the collision portion 52 moves to the positioning position 53, so that the posture of the umbrella 22 relative to the frame 1 is correct in the second position, and thus the posture of the sunshade 221 thereon relative to the frame 1 is correct. When the abutting portion 52 is positioned at the positioning position 53, the positioning position 53 can enable the abutting portion 52 to be positioned on the frame 1, and the abutting portion 52 is connected with the umbrella body 22, so that the umbrella body 22 cannot rotate relative to the base 21 during the process that the driving unit 23 drives the umbrella body 22 to be gradually unfolded, and the driving unit 23 can smoothly open the umbrella body 22 outwards. In addition, considering that the sunshade cloth 221 of the present embodiment has no front-rear division, there are two interference parts 52, when the sunshade umbrella 2 is located at the second position, one of the interference parts 52 is located at the locating position 53, the connecting line of the two interference parts 52 and the length direction of the frame 1 are disposed parallel to each other, and the connecting line of the two interference parts 52 and the rotation axis of the umbrella body 22 rotating relative to the base 21 are perpendicular to each other.

Referring to fig. 11-16, in practical application of the present embodiment, the sunshade 2 further includes a positioning block 24 fixed on the top of the umbrella 22, and the abutting portion 52 is disposed on a circumferential side wall of the positioning block 24. When the umbrella 22 rotates relative to the base 21, the positioning block 24 also rotates synchronously with the umbrella 22, and when the positioning block 24 is limited at the positioning position 53, the positioning block 24 and the umbrella 22 are limited at the positioning position 53, and at this time, neither the positioning block 24 nor the umbrella 22 can rotate relative to the base 21. Therefore, the positioning block 24 is arranged on the sunshade umbrella 2 to solve the problem of deviation correction of the umbrella body 22.

Referring to fig. 14 and 16 together, specifically, the guide block 51 has two oppositely disposed guide surfaces 511, the distance between the two guide surfaces 511 gradually decreases along the moving direction of the umbrella 22 from the first position to the second position, and the connection between the two guide surfaces 511 is the above-mentioned positioning position 53. In the preferred embodiment, both guide surfaces 511 are planar and together form a V-shaped structure. In other embodiments, the two guiding surfaces 511 may be curved and jointly form an elliptical structure.

Referring to fig. 11-16, more specifically, the positioning block 24 includes a base 241 and at least one protrusion 242 connected to the base 241, and considering that the sun-shading cloth 221 of the present application is not divided from front to rear, it is preferable in this embodiment to arrange two protrusions 242 on the base 241, the two protrusions 242 are symmetrically arranged on two sides of the base 241, the base 241 is fixed on the umbrella 22, and each protrusion 242 has two abutting surfaces 2421 connected to each other and having a distance gradually decreasing along a direction away from the base 241. In addition, the bump 242 is further provided with a freely rotatable roller 243, the rotation axis of the roller 243 on the bump 242 and the rotation axis of the umbrella 22 rotating relative to the base 21 are parallel to each other, and the above-mentioned abutting portion 52 includes two abutting surfaces 2421 on the two bumps 242 and the roller 243 on the bump 242. Referring to fig. 13-16, the specific working principle may refer to fig. 13 together, when the driving mechanism 3 drives the sunshade umbrella 2 to rotate from the first position to the second position, the roller 243 will abut against the guiding surface 511, the roller 243 will rotate relative to the bump 242 under the guiding of the guiding surface 511, and the guiding surface 511 will also drive the whole positioning block 24 to rotate relative to the base 21, so as to drive the umbrella 22 to synchronously rotate, and finally, the umbrella 22 is positioned at the positioning position 53.

Referring to fig. 17 and fig. 18 together, when the sunshade 2 moves from the first position to the second position, as shown in fig. 18, the connection line between the two abutting portions 52 may be parallel to the rotation axis of the base 21 relative to the frame 1, and the positioning block 24 will be blocked on the guide block 51, so that the umbrella 22 cannot move smoothly to the moving position 53. In this respect, the application also provides a blocking portion 512 on the guide block 51, which blocking portion 512 is arranged along the direction of movement of the umbrella body 22 from the first position to the second position. Referring to fig. 19 and 20 together, the blocking portion 512 is configured to rotate the entire positioning block 24 relative to the base 21 when the umbrella 22 moves from the first position to the second position, so that a connecting line between the two abutting portions 52 and a rotation axis of the base 21 relative to the frame 1 are disposed at an angle, and further one of the abutting portions 52 can smoothly move to the positioning position 53 along the guiding surface 511.

In summary, based on the original structure, the specific structures of the positioning block 24 and the guiding block 51 are adopted, so that the posture of the sunshade cloth 221 relative to the frame 1 can be corrected at the second position no matter how much the sunshade cloth rotates relative to the base 21 after the sunshade cloth 2 is accommodated in the accommodating groove 111.

The foregoing description of the preferred embodiments of the present application has been provided for the purpose of illustrating the general principles of the present application and is not to be construed as limiting the scope of the application in any way. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application, and other embodiments of the present application as will occur to those skilled in the art without the exercise of inventive faculty, are intended to be included within the scope of the present application.
