Description

Technical Field

[0001] The present application relates to the technical field of synchronous belt anti-slipping, and in particular to an anti-slipping device, a canopy assembly and a vehicle. Background Art

[0002] Synchronous belts are widely used in the machinery, automobile and other industries because of their good transmission efficiency, low noise, high transmission accuracy and other advantages. Synchronous belts are usually used in conjunction with synchronous pulleys. They are belt-shaped parts used to transmit power, but in actual use, there are some problems that need to be solved: Synchronous belts have extremely strict requirements on processing dimensional accuracy and installation dimensional accuracy. If there is an installation deviation of the synchronous belt, or if the synchronous belt is stretched and deformed due to long-term force during use, the tension of the synchronous belt is too small, and the synchronous belt and the synchronous pulley are too loose, resulting in the problem of the synchronous belt jumping or falling off the synchronous pulley during operation, affecting the transmission stability. Summary of the invention

In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0046] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

[0049] The present application provides a vehicle, which can be any type of mature vehicle in the prior art, such as a sedan, an SUV, an MPV, etc. It can be a gasoline vehicle, a pure electric vehicle, a gasoline-electric hybrid vehicle, etc., and can be flexibly selected according to actual needs.

[0050] The vehicle at least includes a vehicle body and a skylight assembly, and the skylight assembly is installed on the vehicle body.

[0051] The ‌skylight assembly‌ refers to the complete components of the car skylight, including the glass assembly, sunshade assembly, controller assembly and motor assembly. The main function of the skylight assembly is to provide lighting and decorative effects inside the car, while adjusting the light and temperature through the sunshade and controller.

[0052] Specifically in one embodiment of the present application, the skylight assembly includes skylight glass, a sunshade, a power source and an anti-slip device 100 .

[0053] The sunshade is arranged on the side of the skylight glass facing the interior of the vehicle, that is, the sunshade is arranged inside the vehicle, so that the sunshade can be protected by the outside of the skylight glass, and it is also easier to operate and clean the sunshade.

[0054] The sunshade can cover or open the skylight glass, and the sunshade is connected to a synchronous belt 200; the anti-slip device 100 is arranged in conjunction with the synchronous belt 200, the synchronous belt 200 is wound around the synchronous pulley 20, and the power source is connected to the synchronous pulley 20 in transmission.

[0055] For example, when the sunshade is opened, the power source drives the synchronous pulley 20 to rotate clockwise, and the synchronous pulley 20 drives the synchronous belt 200 and the sunshade to move in the direction of opening the skylight glass, but at this time, the part of the synchronous belt 200 located above the synchronous pulley 20 will be loose; on the contrary, when the sunshade is closed, the power source drives the synchronous pulley 20 to rotate counterclockwise, and the synchronous pulley 20 drives the synchronous belt 200 and the sunshade to move in the direction of closing the skylight glass, but at this time, the part of the synchronous belt 200 located below the synchronous pulley 20 will be loose. The phenomenon of the loosening of the synchronous belt 200 is commonly known as the elastic edge phenomenon. If it is not intervened, the synchronous belt 200 is very likely to jump off the synchronous pulley 20. In view of this, the present application adopts the installation of an anti-slip device 100 near the synchronous belt 200, which can intervene in the loosening of the synchronous belt 200, thereby effectively solving the above-mentioned jumping problem.

[0056] Optionally, the power source may be, but is not limited to, a motor, a combination of a motor and a reducer, and the like.

[0057] Specifically, see Figure 1 and Figure 2 , is an anti-slip device 100 shown in one embodiment of the present application, which includes a mounting seat 10, a synchronous pulley 20 and an anti-slip baffle 30.

[0058] The synchronous pulley 20 is rotatably arranged on the mounting seat 10, and the synchronous pulley 20 is used to be wound with the synchronous belt 200 so that the synchronous pulley 20 and the synchronous belt 200 are matched in transmission. It can be understood that the synchronous pulley 20 and the synchronous belt 200 are meshed through synchronous teeth to prevent slipping and ensure stable transmission.

[0059] The anti-slip baffle 30 is disposed on the mounting seat 10 , and the anti-slip baffle 30 is disposed outside the synchronous belt 200 to limit the synchronous belt 200 from moving away from the synchronous pulley 20 along the first direction.

[0060] Specifically, the anti-slip baffle 30 is disposed around the outer side of the arc-shaped portion of the synchronous belt 200 wound around the synchronous pulley 20 , that is, the synchronous belt 200 is located between the anti-slip baffle 30 and the synchronous pulley 20 .

[0061] For example, the first direction specifically refers to the X-axis direction. That is, the anti-slip baffle 30 can limit the synchronous belt 200 from moving toward the outside of the synchronous belt pulley 20 along the radial direction of the synchronous belt pulley 20, thereby preventing the synchronous belt 200 from jumping off.

[0062] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the anti-slip device 100 of this solution is applied to the transmission working environment after the synchronous belt 200 and the synchronous pulley 20 are assembled, so as to prevent the synchronous belt 200 from jumping teeth or falling out, thereby improving the installation reliability of the synchronous belt 200 and the synchronous pulley 20.

[0063] Specifically, the synchronous pulley 20 is installed on the mounting base 10 and has the freedom of rotation. The synchronous belt 200 is wound around the outside of the synchronous pulley 20, and the teeth of the synchronous belt 200 are meshed with the teeth of the synchronous pulley 20. Then, the anti-slip baffle 30 is installed on the mounting base 10, and the anti-slip baffle 30 is placed close to the synchronous pulley 20, so that the anti-slip baffle 30 can be surrounded on the outside of the synchronous belt 200; in this way, even if the synchronous pulley 20 drives the synchronous belt 200 to rotate and there is a loose edge phenomenon, or the synchronous belt 200 itself has an installation deviation or tensile deformation, since the anti-slip baffle 30 has the function of blocking the synchronous belt 200 from moving away from the synchronous pulley 20 in the first direction, the synchronous belt 200 cannot loosen from the synchronous pulley 20, and then there will be no problem of tooth jumping or loosening, ensuring that the synchronous belt 200 can always effectively mesh with the synchronous pulley 20 and the transmission is reliable, thereby ensuring the stability of the transmission.

[0064] In the present application, the mounting seat 10 is mainly used to bear the load generated during the operation of the sunshade, prevent the synchronous pulley 20 from shifting left or right or front and back after being subjected to force, and ensure the position accuracy and matching relationship of each component.

[0065] For example, the mounting base 10 may be made of plastic or metal, and preferably, the mounting base 10 is made of PA66-GF30. During actual installation, the mounting base 10 may be fixed to the glass edging by at least one of screwing, clamping, welding, riveting, and bonding.

[0066] Please continue reading Figure 1 and Figure 2In an optional embodiment, the mounting seat 10 is provided with a mounting platform 11, and the anti-slip baffle 30 includes a mounting block 31 and a baffle body 32 connected to each other, the mounting block 31 is arranged on the mounting platform 11, the baffle body 32 is an arc-shaped structure, and the concave side 321 of the baffle body 32 is arranged toward the synchronous pulley 20, and the concave side 321 of the baffle body 32 is used to fit with the gap of the synchronous belt 200.

[0067] The mounting block 31 is designed to be connected with the mounting platform 11, so that the anti-slip baffle 30 can be fixed to the mounting seat 10 as a whole, and the mounting platform 11 is located on the side of the baffle body 32 away from the synchronous pulley 20 and the synchronous belt 200, so that interference can be avoided. Since the synchronous pulley 20 and the part of the synchronous belt 200 wound around the synchronous pulley 20 are both convex arc-shaped structures, the baffle body 32 is designed to be an arc-shaped structure, and the concave side 321 of the baffle body 32 is facing the synchronous belt 200 and is in clearance with the synchronous belt 200, so as to form a better enclosure effect, a larger enclosure area for the synchronous belt 200, and a better anti-slip effect; in addition, while playing the role of anti-slip, it can also help to constrain the arc shape of the synchronous belt 200, so that the synchronous belt 200 and the synchronous pulley 20 keep more teeth meshing during operation, and avoid the synchronous belt 200 from jumping teeth or slipping out during the rotation of the synchronous pulley 20.

[0068] It should be noted that when the sunshade is in operation, the synchronous belt pulley 20 rotates to drive the synchronous belt 200 to rotate, and the synchronous belt 200 will have loose edges. The loosening of the synchronous belt 200 will lead to insufficient meshing teeth between the synchronous belt 200 and the synchronous belt pulley 20. Since the teeth of the synchronous belt 200 are flexible, when the number of meshing teeth is small, the running resistance of the sunshade is greater than the rigidity of the teeth of the synchronous belt 200, and the teeth of the synchronous belt 200 are prone to rigid deformation, which is manifested as the synchronous belt 200 and the synchronous belt pulley 20 slipping (i.e., jumping teeth). If the degree of loosening is more serious, the synchronous belt 200 will directly jump off the synchronous belt pulley 20 and fall off. The baffle body 32 with an arc-shaped structure can well solve this technical problem.

[0069] In the present application, the material of the anti-slip baffle 30 can be selected from plastic or metal. Preferably, the material of the anti-slip baffle 30 is PA66-GF30.

[0070] Please continue reading Figure 3 In order to make the anti-slip baffle 30 have a good anti-slip effect on the synchronous belt 200 while not contacting the synchronous belt 200 to cause friction, wear and motion interference, the distance d between the concave side 321 of the baffle body 32 and the outer side surface of the synchronous belt 200 is designed to be in the range of 5mm~7mm; for example, the distance d in this application is 6mm.

[0071] Furthermore, in order to facilitate quick and reliable assembly and fixation of the mounting platform 11 and the mounting block 31, in one embodiment, one of the mounting platform 11 and the mounting block 31 is provided with a positioning protrusion 111, and the other of the mounting platform 11 and the mounting block 31 is provided with a positioning groove 311, and the positioning protrusion 111 is clamped in the positioning groove 311.

[0072] Please continue reading Figure 1 and Figure 2 Preferably, on the basis of the above embodiment, a first positioning protrusion 111a and a second positioning protrusion 111b are convexly provided on the mounting platform 11, the first positioning protrusion 111a and the second positioning protrusion 111b are arranged at intervals, the mounting block 31 is provided with a first positioning groove 311a and a second positioning groove 311b, the notch of the first positioning groove 311a and the notch of the second positioning groove 311b are arranged back to back, the first positioning protrusion 111a is clamped in the first positioning groove 311a, and the second positioning protrusion 111b is clamped in the second positioning groove 311b.

[0073] On the one hand, the two sets of clamping structures, namely, the first positioning protrusion 111a and the first positioning groove 311a are clamped together, and the second positioning protrusion 111b and the second positioning groove 311b are clamped together, can further improve the assembly strength and firmness of the mounting platform 11 and the mounting block 31; on the other hand, since the notch of the first positioning groove 311a and the notch of the second positioning groove 311b are arranged back to back, the two sets of clamping structures form a limiting effect on each other, which can effectively prevent the mounting block 31 from loosening and deviating in one direction, while not affecting the enclosing effect of the baffle body 32 on the synchronous belt 200.

[0074] Please continue reading Figure 1 and Figure 2 Further, on the basis of any of the above embodiments, the anti-slip device 100 further includes a fixing member, and the mounting block 31 is mounted on the mounting platform 11 through the fixing member. In this way, the anti-slip baffle 30 and the mounting seat 10 can be assembled and fixed.

[0075] Specifically, in one embodiment, the fixing member includes a threaded component 40, the mounting platform 11 is provided with a threaded hole 112, the mounting block 31 is provided with a through hole 312 opposite to the threaded hole 112, and the threaded component 40 passes through the through hole 312 and is screwed into the threaded hole 112 to screw the mounting block 31 to the mounting platform 11. The threaded component 40 is used to lock and fix the mounting block 31 to the mounting platform 11, thereby further improving the installation strength and stability of the anti-slip baffle 30, and preventing the anti-slip baffle 30 from loosening due to environmental vibration during vehicle driving.

[0076] Please continue reading Figure 4 and Figure 5In the present application, the mounting seat 10 is provided with an axial hole 12, and the synchronous pulley 20 includes a wheel shaft 21 and a wheel body 22 connected to each other, the wheel shaft 21 is rotatably arranged in the axial hole 12, and the wheel body 22 is used to be wound with the synchronous belt 200. The wheel shaft 21 is inserted into the axial hole 12 to obtain a rotational freedom, so that the synchronous pulley 20 can be driven by the motor to rotate, thereby driving the synchronous belt 200 to move, and the synchronous belt 200 drives the sunshade to move, thereby realizing the opening or closing operation of the sunshade.

[0077] Furthermore, the wheel circumference of the wheel body 22 is convexly provided with a first baffle 23 and a second baffle 24, both of which extend outwardly along the radial direction of the wheel body 22, and the first baffle 23 and the second baffle 24 are arranged at intervals along the axial direction of the wheel body 22 to form a wheel groove 25, which is used to accommodate the synchronous belt 200, and the first baffle 23 and the second baffle 24 are used to limit the loosening of the synchronous belt 200 along the second direction. That is, with the blocking effect of the first baffle 23 and the second baffle 24, the synchronous belt 200 can be prevented from moving along the second direction on the synchronous belt pulley 20, and the synchronous belt 200 can be prevented from jumping off.

[0078] For example, the second direction may refer to the Y-axis direction, and may also be understood as the axial direction of the synchronous pulley 20 .

[0079] Please continue reading Figure 5 On the basis of the above embodiment, further, a plurality of first baffles 23 are provided, and the plurality of first baffles 23 are arranged at intervals along the circumferential direction of the wheel body 22; a plurality of second baffles 24 are provided, and the plurality of second baffles 24 are arranged at intervals along the circumferential direction of the wheel body 22; the first baffles 23 and the second baffles 24 are arranged staggered in the circumferential direction of the wheel body 22.

[0080] Preferably, the plurality of first baffles 23 and the plurality of second baffles 24 are arranged in a staggered manner in the circumferential direction of the wheel body 22 .

[0081] On the one hand, as the synchronous pulley 20 rotates, the first baffle 23 and the second baffle 24 in different positions can realize continuous blocking and limiting of the synchronous belt 200, ensuring that the synchronous belt 200 will not move along the Y-axis direction and thus jump out; on the other hand, compared with the symmetrical structural design of the first baffle 23 and the second baffle 24 in the traditional technology, the asymmetric structural design of the first baffle 23 and the second baffle 24 in this scheme which is staggered in the circumferential direction is not only easier to demold, but also reduces the mold cost; because the symmetrical structural design requires demolding in four directions, while the asymmetric design only requires demolding in two directions; and with the asymmetric structural arrangement, the parting line avoids the tooth shape, thereby improving the accuracy of the tooth surface.

[0082] like Figure 5As shown, it is easy to understand that the circumferential surface of the synchronous belt pulley 20 is provided with a tooth groove 26, and the tooth groove 26 is used to mesh with the teeth on the inner side of the synchronous belt 200. The meshing transmission structure formed by the tooth groove 26 and the teeth ensures traditional stability and transmission efficiency and avoids slipping.

[0083] Please continue reading Figure 1 , Figure 2 and Figure 6 In addition, on the basis of any of the above embodiments, the anti-slip device 100 further includes a tensioning mechanism 50, which is disposed on the mounting seat 10 and arranged on the side of the synchronous pulley 20 away from the anti-slip baffle 30, and the tensioning mechanism 50 is used to abut against the synchronous belt 200 to achieve tensioning of the synchronous belt 200 along the third direction. By tensioning the synchronous belt 200 along the third direction through the tensioning mechanism 50, the slack state of the synchronous belt 200 can be improved, so that the synchronous belt 200 and the synchronous pulley 20 are more firmly and effectively connected, and the synchronous pulley 20 and the synchronous belt 200 are effectively transmitted.

[0084] For example, the third direction specifically refers to Figure 2 The Z-axis direction.

[0085] Optionally, the tensioning mechanism 50 may be disposed below, above or inside the synchronous belt 200 , which may be flexibly selected according to actual needs and is not specifically limited here.

[0086] Specifically, in an optional embodiment, the mounting seat 10 is provided with a carrier 13, the carrier 13 is arranged on the side of the synchronous pulley 20 away from the anti-slip baffle 30, and the tensioning mechanism 50 includes an elastic member 51 and a tensioning column 52, the elastic member 51 is arranged on the carrier 13, and the tensioning column 52 abuts against the elastic member 51, so that the tensioning column 52 can elastically abut against the synchronous belt 200. The elastic member 51 in the compressed state applies an elastic thrust to the tensioning column 52, so that the tensioning column 52 can press the synchronous belt 200 along the third direction, thereby improving the slack state of the synchronous belt 200 to tighten the synchronous belt 200. In addition, the tensioning column 52 elastically abuts against the synchronous belt 200, which can avoid excessive extrusion force applied to the synchronous belt 200, resulting in deformation or even crushing of the synchronous belt 200.

[0087] For example, the elastic member 51 may be, but is not limited to, any one of a spring, a spring sheet, an elastic column, etc., and may be flexibly selected according to actual needs.

[0088] Furthermore, the platform 13 is provided with a guide slide hole 131, which is arranged on two opposite sides of the platform 13, and the tensioning column 52 is telescopically and slidably arranged in the guide slide hole 131. According to factors such as the installation position of different synchronous belts 200 and the different states of relaxation of the synchronous belts 200, the tensioning column 52 can telescopically slide in the guide slide hole 131, and meet the tensioning needs of different synchronous belts 200 with the help of the elastic force provided by the elastic member 51, thereby improving the performance and application range of the tensioning mechanism 50.

[0089] In particular, the guide hole 131 is set as a limiting hole, which is used to limit the tensioning column 52 from rotating in a circle in the limiting hole, and the shape and size of the cross section of the tensioning column 52 are respectively adapted to the shape and size of the cross section of the limiting hole.

[0090] For example, in the present application, the guide slide hole 131 adopts a cross-shaped hole, and correspondingly the tensioning column 52 adopts a cross-shaped rod. This can prevent the tensioning column 52 from rotating in a circle in the guide slide hole 131 during the rotation of the synchronous belt 200, affecting the tensioning reliability of the synchronous belt 200 by the tensioning column 52. At the same time, it can avoid the tensioning column 52 from causing rotational friction and wear on the synchronous belt 200, which helps to ensure the service life of the synchronous belt 200.

[0091] In the present application, the tensioning column 52 is provided with an arc-shaped protrusion 521, and the arc-shaped protrusion 521 is used for sliding contact with the synchronous belt 200. In this way, the friction resistance and wear between the tensioning column 52 and the synchronous belt 200 are reduced on the basis of obtaining a good tensioning effect, the service life of the synchronous belt 200 is increased, and the motor load and power consumption are reduced.

[0092] In order to prevent the tensioning column 52 from completely falling out of the guide hole 131 under the elastic force of the elastic member 51, in one embodiment, the tensioning mechanism 50 also includes a stop spring 53, and a groove 522 is provided at one end of the tensioning column 52 away from the arc-shaped protrusion 521, and the stop spring 53 is engaged with the groove 522, and the stop spring 53 can be limitedly abutted against the carrier 13.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
