[0058] As shown in Figure 1 , Figure 2 The folding electric vehicle canopy, comprising:

[0059] Supporting column 10 is arranged vertically;

[0060] The arm member 20 is at an acute angle with the upper part of the supporting column 10, the lower end is driven to move up and down on the supporting column 10, and the upper end can be telescopic along the length of itself;

[0061] The support arm 30 is rotatably and slidably connected to the upper end of the support column 10, and one end of the support arm 30 is rotatably connected to the telescopic end of the telescopic arm 20.

[0062] The shielding component 60 is located on the support arm 30 and has a shielding member that can move and spread along the length direction of the support arm 30.

[0063] Specifically, the support column 10 can be made of a section steel and installed on the ground by means of a grouting anchor rod to ensure that it has a certain bearing capacity.

[0064] The telescopic arm 20 can be elongated and retracted, and is connected between the support column 10 and one end of the support arm 30. When the telescopic arm 20 is telescoped, the telescopic arm 20, the support column 10, and the support arm 30 can form a triangular area with a variable shape. The length of the telescopic arm 20 and the upper part of the support column 10 form an acute angle, which can be a manually adjustable angle or a fixed angle. When the fixed angle is used, one end of the telescopic arm 20 can be directly fixedly connected to the support column 10. When the adjustable angle is used, one end of the telescopic arm 20 can be rotatably connected to the support column 10 and locked.

[0065] The support arm 30 is a bearing component of the shielding component 60 and is movably installed on the upper end of the support column 10 by the support member 40. The movement mainly includes rotation and sliding relative to the upper end of the support column 10.

[0066] The shielding component 60 is used to shield parked vehicles such as electric vehicles to reduce the influence of the environment. For example, when the shielding member is driven to move and spread, it can be covered above the parked vehicles.

[0067] It is explained that the support column 10, the telescopic arm 20, and the support arm 30 can be a pair and arranged at intervals. At this time, the shielding component 60 is located on the pair of support arms 30, i.e., the shielding member moves and spreads on the pair of support arms 30.

[0068] When the folding electric vehicle canopy is initially used, the telescopic arm 20 is at a certain height and forms a certain angle with the support base. Figure 2 As shown in the figure, the left side of the connection point between the telescopic arm 20 and the support arm 30 is defined for convenience of description.

[0069] As shown in the figure, the left side of the connection point between the telescopic arm 20 and the support arm 30 is defined for convenience of description. Figure 2As shown in (a), when the extendable arm component 20 is in the extended state, the upper end of the extendable arm component 20 drives the left end of the support arm 30 to "tilt" upward. Since the support arm 30 can rotate and slide relative to the support base column 10, that is, the support base column 10 provides the support arm 30 with a movable support point. The support arm 30 can adaptively adjust after the left end is tilted up, and under the lever principle, the right end of the support arm 30 "sinks" downward. The support arm 30 as a whole is an inclined structure with the left side higher than the right side. Compared with the horizontal plane, this inclination angle is small, which helps rainwater and round debris to slide off, and ensures that there is enough parking space below the support arm 30.

[0070] like Figure 2 As shown in (b), when the extender arm component 20 is in the retracted state, the upper end of the extender arm component 20 drives the left end of the support arm 30 to "sink" downward. The support arm 30 can adaptively adjust after the left end sinks, and under the lever principle, the right end of the support arm 30 "tilts" upward. The support arm 30 as a whole has an inclined structure with the left end lower and the right end higher. Compared with the horizontal plane, this inclined angle is relatively large. On the one hand, it can force snow and debris that is not easy to slide off to be cleared. On the other hand, the angle between the support arm 30 and the vertical support column 10 is reduced, which makes it easier for the support arm 30 to fold closer together.

[0071] like Figure 2 As shown in (c), the lower end of the extension arm component 20 is driven to move downward, and the upper end of the extension arm component 20 will pull the support arm 30 to move downward. The support arm 30 rotates and slides relative to the support base column 10 to make adaptive adjustments. The support arm 30 moves closer to the support base column 10, reducing the overall space occupied and making the overall structure more compact after folding.

[0072] In some examples of this utility model, such as Figure 1 , Figure 3 As shown, a support member 40 is connected between the support arm 30 and the upper end of the support base column 10;

[0073] The support member 40 is rotatably mounted on the upper end of the support base column 10 and has a sliding groove or a slider;

[0074] The support arm 30 is slidably located in the groove or has a linear slide rail that matches the slider installed at its bottom.

[0075] Specifically, the support member 40 is used to connect the support arm 30 to the support base column 10, that is, to provide a movable support point for the support arm 30;

[0076] The two ends of the support member 40 can be rotatably mounted on the upper end of the support base column 10 via bearings, and the slide groove or slider can match the support arm 30 to ensure that the support arm 30 slides on the support member 40.

[0077] In some examples of this utility model, such as Figure 1As shown, the lower end of the support column 10 is provided with a first cylinder 50, and a sliding member 11 is slidably arranged in the middle part thereof;

[0078] The output end of the first cylinder 50 is connected with the sliding member 11;

[0079] One end of the stretching arm member 20 is connected with the sliding member 11;

[0080] Specifically, the sliding member 11 is installed on the support column 10 through a linear slide rail; when the first cylinder 50 is started, the output end thereof is extended and contracted to drive the sliding member 11 to move up and down on the support column 10, thereby driving the stretching arm member 20 to move.

[0081] In some examples of the utility model, as shown in Figure 5 As shown, the stretching arm member 20 has a first arm 21 and a second arm 22;

[0082] The first arm 21 is fixed at one end or is adjustably and limitingly connected with the sliding member 11, and the first arm 21 is provided with a second cylinder 23; the second arm 22 is slidably arranged opposite to the first arm 21 and is rotatably connected with a support arm 30 at one end;

[0083] The output end of the second cylinder 23 is connected with the second arm 22;

[0084] Further, as shown in Figure 5 The first arm 21 is provided with a strip-shaped groove 211 arranged along the length direction thereof;

[0085] The second arm 22 is provided with a limiting rod 221 slidably arranged in the strip-shaped groove 211;

[0086] A controller is connected with the first cylinder 50 and the second cylinder 23 and controls the corresponding actions thereof;

[0087] Specifically, the first arm 21 and the second arm 22 can both have a hollow rectangular structure, and the second arm 22 is sleeved in the first arm 21 to slide relatively; one end of the second arm 22 can be provided with an ear seat and is rotatably connected with the support arm 30;

[0088] When the second cylinder 23 is started, the second arm 22 is driven to move relatively to the first arm 21, i.e. the stretching arm member 20 is adjusted to extend and contract;

[0089] When the first arm 21 and the second arm 22 both have a hollow cylindrical structure, the limiting rod 221 of the second arm 22 can be circumferentially limited in the strip-shaped groove 211 of the first arm 21, and the length of the strip-shaped groove 211 determines the extension and contraction stroke of the stretching arm member 20;

[0090] The first cylinder 50 and the second cylinder 23 can adopt a hydraulic or electric cylinder structure and are controlled to stretch and retract by a controller, and the controller can adopt a fixed type and a remote type, namely, when the fixed type is adopted, a corresponding control screen can be arranged on the support column 10, and when the remote type is adopted, corresponding control can be performed by a remote terminal through wireless signals.

[0091] In some examples of the utility model, a seat plate 212 is fixed at the end of the first lever arm 21;

[0092] The seat plate 212 is rotationally installed on the sliding piece 11, and a positioning rod is arranged on the seat plate 212; a plurality of positioning holes are arranged on the sliding piece 11 in a circumferential direction with the rotation axis of the seat plate 212 as the center;

[0093] When the stretching arm part 20 rotates by a certain angle relative to the support column 10, the positioning rod is inserted into the positioning hole through the seat plate 212 to limit the angle;

[0094] Specifically, the acute angle between the stretching arm part 20 and the support column 10 determines the force of the stretching arm part 20 during the folding process of the support arm 30, namely, when the acute angle between the stretching arm part 20 and the support column 10 is small, the support arm 30 rotates on the upper end of the support column 10 through the support piece 40, and according to the principle of a lever, the support arm 30 has the same posture, and the stretching arm part 20 has relatively large overall force, but when the stretching arm part 20 moves downward, the support arm 30 is more close to the support column 10 and is more compact; when the acute angle between the stretching arm part 20 and the support column 10 is large, the support arm 30 has the same posture, and the stretching arm part 20 has relatively small overall force, but is not compact enough;

[0095] The seat plate 212 can be directly connected with the sliding piece 11 through bolts or welding, or can be connected through rotation and angle limiting by the positioning rod, namely, when the stretching arm part 20 rotates by a certain angle relative to the support column 10, the positioning rod is inserted into the positioning hole through the seat plate 212 to be locked and fixed in angle, which is suitable for different use environments.

[0100] Specifically, the support beam 70 can be provided with a sliding groove matched with the upper end of the support arm 30, so as to realize sliding connection;

[0101] As shown in the figure, Figure 6 When the shielding member is the shade cloth 68, the shade cloth 68 is in a rolled state under the action of the initial coiled spring, the shade cloth 68 is gradually unfolded when the support beam 70 is driven to move away from the winding shaft 67 on the support arm 30, and the shade cloth 68 is gradually rolled up when the support beam 70 is driven to move close to the winding shaft 67, so as to realize the extension and retraction action of the shade cloth 68;

[0102] As shown in the figure, Figure 7 When the shielding member is the solar panel 69, the support beam 70 is driven to move away from the winding shaft 67 on the support arm 30, the skeleton in a plurality of "W" connections is gradually unfolded, and the solar panel 69 is unfolded, and when the support beam 70 is driven to move close to the winding shaft 67, the skeleton in a plurality of "W" connections is gradually retracted, and the solar panel 69 is folded;

[0103] In this example, the shielding member can be the shade cloth 68 which has a good shielding effect, or the solar panel 69 which can shield and perform photovoltaic power generation, and the shielding part 60 can be modularized, and can be disassembled and replaced according to the use environment, for example, in an area with more rain and snow, the shielding part 60 with the shade cloth 68 is installed, and in an area with sufficient sunlight, the shielding part 60 with the solar panel 69 is installed;

[0104] In addition, when disassembled and replaced, the first cylinder 50 drives the extension arm part 20 to move to the lowermost position, the extension arm part 20 is in a retracted state, and the support beam 70 moves close to the left end of the support arm 30, at this time, the support arm 30 is folded and close to the support column 10, so that personnel can install the shielding part 60 on the left end of the support arm 30.
