Description

Technical Field

[0001] The present application relates to the technical field of sunshades, and in particular to a curtain body moving device, a sunshade assembly and a glass assembly. Background Art

[0002] Currently, most sunshades of existing vehicles adopt electric sunshades. During the process of driving the curtain body to open and roll up, some curtain body moving devices of electric sunshades will adopt the method of synchronous belt rotation to drive the curtain body to open and roll up. Among them, during the rotation of the synchronous belt, the belt body of the synchronous belt will undergo stretching deformation, and the length of the synchronous belt gradually increases, resulting in the loosening of the synchronous belt. The belt bodies on both sides of the synchronous belt are prone to contact and interference, resulting in an increase in the resistance of the synchronous belt rotation, which easily leads to jamming of the curtain body moving device, and further leads to abnormal operation of the sunshade. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a curtain body moving device, a sunshade assembly and a glass assembly. During the process of driving the curtain body to open and roll up by using the curtain body moving device, it can make the belt bodies on both sides of the synchronous belt always remain in a taut state, and solve the problem that the curtain body moving device is prone to jamming due to the loosening of the synchronous belt, and further lead to abnormal operation of the sunshade assembly.

[0004] The embodiments of the present application provide a curtain body moving device for driving the movement of the curtain body. The curtain body moving device includes:

[0005] A fixed seat;

[0006] A first pulley and a second pulley, both the first pulley and the second pulley are installed on the fixed seat, both the first pulley and the second pulley can rotate relative to the fixed seat, and the first pulley and the second pulley are spaced apart relative to each other along the unfolding direction of the curtain body;

[0007] A synchronous belt for driving the movement of the curtain body. The synchronous belt is sleeved outside the first pulley and the second pulley. When the first pulley rotates, it can drive the synchronous belt to rotate, or when the second pulley rotates, it can drive the synchronous belt to rotate. The synchronous belt includes a first belt body and a second belt body. Both the first belt body and the second belt body are located between the first pulley and the second pulley, and the first belt body and the second belt body are spaced apart relative to each other along the height direction of the curtain body moving device;

[0008] A tensioning mechanism including a first tensioning member and a second tensioning member. The first tensioning member abuts against the first belt body, and the second tensioning member abuts against the second belt body.

[0009] In the curtain body moving device provided by the embodiment of the present application, by arranging a tensioning mechanism, the first tensioning member and the second tensioning member of the tensioning mechanism respectively abut against the relatively arranged first belt body and the second belt body in the synchronous belt, so that the belt bodies on the upper and lower sides of the synchronous belt can always be kept taut during operation, thereby solving the problems that abnormal noises occur in the synchronous belt, skipping teeth and climbing noises are generated due to the slack of one side belt body of the synchronous belt during rotation, and the rotation resistance of the synchronous belt increases, resulting in an increase in the system resistance of the curtain body moving device, causing the curtain body moving device to get stuck and the sunshade curtain assembly to operate abnormally.

[0010] In a possible implementation manner, the tensioning mechanism further includes an elastic member, the elastic member is connected to both the first tensioning member and the second tensioning member, and the elastic member is in a deformed state. The elastic deformation force generated when the elastic member is in a deformed state is used to press the first tensioning member against the first belt body of the synchronous belt and to press the second tensioning member against the second belt body of the synchronous belt, so as to realize that the first tensioning member abuts against the first belt body and the second tensioning member abuts against the second belt body, and further realize that the belt bodies on the upper and lower sides of the synchronous belt can always be kept taut during rotation.

[0011] In addition, since the elastic member has elasticity, the elastic member can automatically adjust the elastic deformation force on the first tensioning member and the second tensioning member according to the looseness of the synchronous belt. While ensuring the tightness of the synchronous belt, it is not necessary for the staff to frequently adjust the tensioning mechanism, avoiding the problem that when using a tensioning pulley to tension the synchronous belt, it is necessary to manually adjust the position of the tensioning pulley to adjust the tightness of the synchronous belt. At the same time, it avoids the problem that as the synchronous belt loosens, it is necessary to frequently adjust the position of the tensioning pulley, resulting in high maintenance costs. It also can avoid the problem that when using the tensioning pulley to abut against the synchronous belt, the tensioning pulley becomes loose after long-term use, resulting in low transmission efficiency of the synchronous belt.

[0012] In a possible implementation, both the first tensioning member and the second tensioning member are installed on the fixed seat, and the first tensioning member and the second tensioning member are arranged at intervals relative to each other. The elastic member is connected between the first tensioning member and the second tensioning member. By arranging the elastic member to be connected between the first tensioning member and the second tensioning member, the elastic member generates a tensile force on both the first tensioning member and the second tensioning member, so that the first tensioning member and the second tensioning member respectively always hold against the first belt body and the second belt body of the synchronous belt. The two side belt bodies of the synchronous belt can always remain in a taut state during rotation, thereby solving the problem that one side belt body of the synchronous belt will become loose during rotation, and solving problems such as abnormal noise, tooth skipping and climbing noise of the synchronous belt caused by the looseness of one side belt body of the synchronous belt during rotation, and the problem that the rotation resistance of the synchronous belt increases, resulting in an increase in the system resistance of the curtain moving device and causing the curtain moving device to get stuck and the sunshade curtain assembly to operate abnormally. In addition, the stretching elasticity of the elastic member can reduce the tolerances and deformations existing in the first tensioning member and the second tensioning member itself. Also, without changing the installation positions of the first tensioning member and the second tensioning member, the tension force on the synchronous belt can be adjusted only by replacing the specification attributes of the elastic member and the installation angles of the first tensioning member and the second tensioning member, greatly reducing the manpower and difficulty required for installing the tensioning mechanism.

[0013] In a possible implementation, the fixed seat includes a first mounting member and a second mounting member. The first mounting member and the second mounting member are arranged at intervals relative to each other. The first tensioning member is installed on the first mounting member, and the second tensioning member is installed on the second mounting member.

[0014] In a possible implementation, the first mounting member is provided with a first mounting hole, and the second mounting member is provided with a second mounting hole. Both the first tensioning member and the second tensioning member include a first mounting portion, a holding portion, and a limiting portion. The holding portion is connected to the first mounting portion, and the limiting portion protrudes from the periphery of the first mounting portion.

[0015] The first mounting portion of the first tensioning member is installed in the first mounting hole, and the first mounting portion of the second tensioning member is installed in the second mounting hole.

[0016] In a possible implementation, the first tensioning member passes through the first mounting hole, and the first mounting portion of the first tensioning member is installed in the first mounting hole. The holding portion of the first tensioning member holds against the first belt body. The limiting portion of the first tensioning member protrudes relative to the first mounting hole, and the limiting portion of the first tensioning member holds against the surface of the first mounting member facing away from the synchronous belt.

[0017] The second tensioning member passes through the second mounting hole, and the first mounting portion of the second tensioning member is installed in the second mounting hole. The holding portion of the second tensioning member holds against the second belt body. The limiting portion of the second tensioning member protrudes relative to the second mounting hole, and the limiting portion of the second tensioning member holds against the surface of the second mounting member facing away from the synchronous belt.

[0018] The limiting portion of the first tensioning member and the limiting portion of the second tensioning member can respectively limit the first tensioning member and the second tensioning member to the first mounting hole and the second mounting hole of the fixing seat by abutting against the first mounting member and the second mounting member, thereby preventing the tensioning mechanism from being separated from the fixing seat and reducing the impact on other parts of the curtain moving device when adjusting the tensioning mechanism. In addition, the tensioning mechanism can be detachably mounted on the fixing seat. On the one hand, the tensioning mechanism can be conveniently and quickly mounted on the fixing seat without removing the synchronous belt. On the other hand, when replacing the tensioning mechanism, there is no need to disassemble the entire fixing seat, thereby reducing the difficulty of maintenance and replacement.

[0019] In a possible embodiment, the first tensioning member and the second tensioning member further include a connecting arm and a second mounting portion, the connecting arm being connected between the first mounting portion and the supporting portion, the second mounting portion being connected to the connecting arm, the second mounting portion and the first mounting portion being arranged on the same side of the connecting arm, and the second mounting portion and the first mounting portion being arranged relative to each other and spaced apart, and the elastic member being connected between the second mounting portion of the first tensioning member and the second mounting portion of the second tensioning member.

[0020] In a possible implementation, the first tensioning member and the second tensioning member further include an anti-slip portion, which is connected to an end of the abutting portion away from the connecting arm, and the anti-slip portion protrudes relative to a peripheral side of the abutting portion.

[0021] In a possible embodiment, the elastic member includes a first elastic part and a second elastic part, both of which are installed on a fixed seat, and the first elastic part and the second elastic part are arranged at a relative interval, and both of which are in a deformed state, and the first tensioning member is fixedly connected to the first elastic part, and the second tensioning member is fixedly connected to the second elastic part. The elastic force generated by the first elastic part is used to press the first tensioning member toward the first belt body of the synchronous belt, and the elastic force generated by the second elastic part is used to press the second tensioning member toward the second belt body of the synchronous belt, so that the belt bodies on both sides of the synchronous belt are always in a taut state during the rotation process, and the problems of abnormal noise of the synchronous belt, tooth skipping and climbing noise caused by the relaxation of one side of the belt body during the rotation process are solved, and the problems of increased rotation resistance of the synchronous belt, increased system resistance of the curtain moving device, jamming of the curtain moving device, and abnormal operation of the sunshade assembly are solved.

[0022] In a possible implementation, both the first elastic part and the second elastic part include a first connection end, a second connection end, and a torsion part. The first connection end and the second connection end are connected to opposite ends of the torsion part.

The first tensioning member is fixedly connected to the second connection end of the first elastic part, and the second tensioning member is fixedly connected to the second connection end of the second elastic part. By virtue of the torsion part of the first elastic part being in a deformed state, a torsion force is generated on the first tensioning member, thereby pressing the first tensioning member against the first belt body of the synchronous belt, and further realizing the abutment of the first tensioning member against the first belt body of the synchronous belt. By virtue of the torsion part of the second elastic part being in a deformed state, a torsion force is generated on the second tensioning member, thereby pressing the second tensioning member against the second belt body of the synchronous belt, and further realizing the abutment of the second tensioning member against the second belt body of the synchronous belt, and further realizing that the belt bodies on both sides of the synchronous belt are always in a taut state during rotation.

[0023] In a possible implementation, the first mounting member is provided with a first mounting hole, the first elastic part is mounted in the first mounting hole, the second mounting member is provided with a second mounting hole, and the second elastic part is mounted in the second mounting hole. By arranging the first elastic part and the second elastic part of the elastic member to be respectively mounted in the first mounting hole and the second mounting hole, the tensioning mechanism can be detachably mounted on the fixed seat, the tensioning mechanism can be replaced without removing the fixed seat, and by using the first elastic part and the second elastic part with different properties, and adjusting the mounting angles of the first tensioning member and the second tensioning member, the magnitude of the abutting force applied to the synchronous belt can be adjusted, thereby realizing the adjustment of the tension force of the synchronous belt. In addition, the first elastic part and the second elastic part in the elastic member are arranged at intervals and do not affect each other. When maintenance and replacement are required, the first elastic part or the second elastic part can be separately removed, saving the maintenance and replacement costs.

[0024] In a possible implementation, the first mounting member is further provided with a first fixing hole, the opening of the first fixing hole is provided on the inner wall of the first mounting hole, the second mounting member is further provided with a second fixing hole, the opening of the second fixing hole is provided on the inner wall of the second mounting hole, and both the first tensioning member and the second tensioning member include a first mounting portion and an abutting portion connected to the first mounting portion. The first mounting portions of the first tensioning member and the second tensioning member are both provided with clamping grooves;

[0025] The torsion part of the first elastic part is sleeved on the periphery of the first mounting portion of the first tensioning member. The first connection end of the first elastic part is clamped in the first fixing hole, the second connection end of the first elastic part is clamped in the clamping groove of the first tensioning member, and the abutting portion of the first tensioning member abuts against the first belt body;

The first connection end of the second elastic part is clamped in the second fixing hole, the second connection end of the second elastic part is clamped in the clamping groove of the second tensioning member, and the abutting part of the second tensioning member abuts against the second belt body.

[0027] In a possible implementation manner, both the first elastic part and the second elastic part include a first connection end, a second connection end and a torsion part. The first connection end and the second connection end are connected to opposite ends of the torsion part.

[0028] The torsion part of the first elastic part is mounted on the first mounting member, the torsion part of the second elastic part is mounted on the second mounting member, and the torsion parts of the first elastic part and the second elastic part are arranged at intervals relative to each other. The elastic member further includes a connecting part, and the connecting part is connected between the first connection end of the first elastic part and the first connection end of the second elastic part. The first tensioning member is fixedly connected to the second connection end of the first elastic part, and the second tensioning member is fixedly connected to the second connection end of the second elastic part.

[0029] The connecting part is used to connect between the first connection end of the first elastic part and the first connection end of the second elastic part, so that the first connection end of the first elastic part and the first connection end of the second elastic part remain fixed. At this time, by adjusting the positions of the first tensioning member and the second tensioning member, the second connection end of the first elastic part can be driven to twist relative to the first connection end of the first elastic part, and the second connection end of the second elastic part can be driven to twist relative to the first connection end of the second elastic part, so as to realize that the torsion parts of the first elastic part and the second elastic part are both in a deformed state. The torsion part of the first elastic part generates a torsion force on the first tensioning member to press the first tensioning member against the first belt body of the synchronous belt, so as to realize the abutment of the first tensioning member and the first belt body of the synchronous belt. The torsion part of the second elastic part generates a torsion force on the second tensioning member to press the second tensioning member against the second belt body of the synchronous belt, so as to realize the abutment of the second tensioning member and the second belt body of the synchronous belt, and further realize that the belt bodies on both sides of the synchronous belt are always in a taut state during rotation, solving the problems such as abnormal noise of the synchronous belt, tooth skipping and climbing noise caused by the relaxation of one side of the belt body during the rotation of the synchronous belt, and the increase of the rotation resistance of the synchronous belt, resulting in the increase of the system resistance of the curtain moving device and the jamming of the curtain moving device, and the abnormal operation of the sunshade curtain assembly.

[0030] In a possible implementation manner, the fixed seat further includes a clamping member. The connecting part is mounted on the fixed seat, and the connecting part is clamped with the clamping member to limit the elastic member on the fixed seat, so as to realize the limitation of the tensioning mechanism on the fixed seat and prevent the tensioning mechanism from disengaging from the fixed seat during the rotation of the synchronous belt.

Detailed implementation manners

[0057] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0058] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the glass assembly 1 provided in the embodiment of the present application when the curtain body 350 is in the retracted state, Figure 2 For Figure 1 schematic structural diagram of the curtain body 350 in the glass assembly 1 shown when it is in the opened state. Among them, Figure 1 and Figure 2 only show part of the structure of the curtain body moving device 310.

[0059] The glass assembly 1 can be applied to scenarios such as vehicles, doors and windows, and glass curtain walls that require light shielding. In the embodiments of the present application, the case where the glass assembly 1 is applied to a vehicle is taken as an example for illustration.

[0060] Among them, for the convenience of description, it is defined that Figure 1 The length direction of the shown glass assembly 1 is the X-axis direction, the width direction is the Y-axis direction, and the thickness direction is the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other in pairs. When describing the glass assembly 1 in the embodiments of the present application, the orientation terms such as "upper", "lower", "front", and "rear" mentioned are based on the Figure 1 orientation shown in the accompanying drawings of the specification. Taking the positive direction of the Z-axis as "upper", the negative direction of the Z-axis as "lower", the positive direction of the X-axis as "front", and the negative direction of the X-axis as "rear", it does not form a limitation on the glass assembly 1 in the actual application scenario.

[0061] Specifically, the glass assembly 1 includes a glass 100 and a sunshade assembly 300. The glass 100 is installed on the vehicle frame. In this embodiment, the glass 100 is the sunroof glass of the vehicle. It can be understood that in other embodiments, the glass 100 can also be a front windshield, a rear windshield, a side window glass, etc.

[0062] The sunshade assembly 300 includes a curtain body moving device 310, a reel 330, and a curtain body 350. The curtain body moving device 310 is installed on the glass 100. The reel 330 is installed on the curtain body moving device 310. The curtain body 350 is wound around the reel 330, and the curtain body 350 is connected to the curtain body moving device 310. Among them, the curtain body 350 is used to block the glass 100. The curtain body 350 includes a retracted state and an open state. The curtain body moving device 310 can drive the reel 330 to rotate, and the curtain body moving device 310 can drive the curtain body 350 to move, so as to realize the switching of the curtain body 350 between the retracted state and the open state.

[0063] Specifically, taking the initial state of the curtain body 350 in the sunshade assembly 300 as the retracted state as an example for description. In the sunshade assembly 300, the curtain body moving device 310 drives the reel 330 to rotate around the first direction (such as clockwise), and the curtain body moving device 310 drives the curtain body 350 to move relative to the reel 330 in the positive direction of the X-axis, that is, drives the curtain body 350 to move from the rear to the front, so as to realize the switching of the curtain body 350 from the retracted state to the open state. At this time, the curtain body 350 blocks the light passing through the glass 100, and the sunshade assembly 300 realizes the light-shielding effect. The curtain body moving device 310 drives the reel 330 to rotate around the opposite direction of the first direction (such as counterclockwise), and the curtain body moving device 310 drives the curtain body 350 to move relative to the reel 330 in the negative direction of the X-axis, that is, drives the curtain body 350 to move from the front to the rear, so as to realize the switching of the curtain body 350 from the open state to the retracted state. At this time, the light can pass through the glass 100 and enter the interior of the vehicle.

[0064] In this embodiment, there are two curtain moving devices 310. The two curtain moving devices 310 are arranged at intervals in the Y-axis direction and are located at opposite ends of the reel 330. Hereinafter, the structure of one curtain moving device 310 will be taken as an example for illustration, and the height direction of the curtain moving device 310 is the Z-axis direction.

[0065] Referring to Figure 1 、 Figure 3 and Figure 4 , Figure 3 is Figure 1 a partial structural schematic diagram of the curtain moving device 310 in the glass assembly 1 shown in Figure 4 is Figure 3 an exploded structural schematic diagram of the curtain moving device 310 shown in Figure 3 The second pulley 50 is not shown in

[0066] The curtain moving device 310 includes a fixed seat 10, a first pulley 30, a second pulley 50 (see Figure 1 ), and a synchronous belt 70. The first pulley 30 and the second pulley 50 are both installed on the fixed seat 10. The synchronous belt 70 is installed on the first pulley 30 and the second pulley 50, and the synchronous belt 70 is used to drive the curtain 350 to move.

[0067] Specifically, the fixed seat 10 includes a first seat body 102, a second seat body 104, and a guide rail 106. The first seat body 102 and the second seat body 104 are arranged at intervals relative to each other along the unfolding direction of the curtain 350, and the guide rail 106 is installed between the first seat body 102 and the second seat body 104.

[0068] The first pulley 30 and the second pulley 50 are installed on the same side of the fixed seat 10. Both the first pulley 30 and the second pulley 50 can rotate relative to the fixed seat 10, and the first pulley 30 and the second pulley 50 are arranged at intervals relative to each other along the unfolding direction of the curtain 350. Among them, the first pulley 30 is installed on the first seat body 102 of the fixed seat 10, and the second pulley 50 is installed on the second seat body 104 of the fixed seat 10.

[0069] The synchronous belt 70 is sleeved on the outer sides of the first pulley 30 and the second pulley 50. The first pulley 30 rotates and can drive the synchronous belt 70 to rotate, or the second pulley 50 rotates and can drive the synchronous belt 70 to rotate. In this embodiment, both the first pulley 30 and the second pulley 50 are toothed pulleys, and the inner surface of the synchronous belt 70 is provided with convex teeth, and the convex teeth are engaged with the gears of the first pulley 30 and the second pulley 50 to realize the rotation of the first pulley 30 and / or the second pulley 50 and drive the synchronous belt 70 to rotate.

[0070] Exemplarily, the timing belt 70 is made of a material with a certain elasticity, with a wire rope or fiberglass as the reinforcement layer, and an annular belt covered with polyurethane or neoprene. In this embodiment, the timing belt 70 is an open belt. It can be understood that in other embodiments, the timing belt 70 can also be a closed belt, and the present application does not limit this. In this embodiment, when the timing belt 70 rotates, the timing belt 70 can drive the curtain body 350 to move, thereby realizing that the curtain body moving device 310 drives the curtain body 350 to move.

[0071] Among them, the timing belt 70 includes a first belt body 71 and a second belt body 73. Both the first belt body 71 and the second belt body 73 are located between the first pulley 30 and the second pulley 50, and the first belt body 71 and the second belt body 73 are relatively spaced apart along the height direction of the curtain body moving device 310. In this embodiment, the first belt body 71 refers to the belt body that is always located on the upper side during the rotation or static state of the timing belt 70, and the second belt body 73 refers to the belt body that is always located on the lower side during the rotation or static state of the timing belt 70. The first belt body 71 includes a first abutting surface, and the second belt body 73 includes a second abutting surface.

[0072] In this embodiment, the curtain body moving device 310 further includes a motor, a slider, and a pull rod. Among them, the motor drives the second pulley 50 to rotate. The second pulley 50 rotates and drives the timing belt 70 to rotate. The timing belt 70 rotates and drives the first pulley 30 to rotate. At this time, the second pulley 50 is the driving pulley, and the first pulley 30 is the driven pulley. It can be understood that in other embodiments, the first pulley 30 can also be the driving pulley, the second pulley 50 is the driven pulley, and the first pulley 30 rotates and drives the timing belt 70 to rotate. The slider is fixedly connected to the timing belt 70. In this embodiment, the slider is connected to the opening of the open belt. One end of the slider is slidably installed on the guide rail 106, and the slider can slide relative to the guide rail 106 along the unfolding direction of the curtain body 350. The other end of the slider is fixedly connected to the pull rod. The pull rod is used to be fixedly connected to the end of the curtain body 350 away from the reel 330.

[0073] In the assembly structure of the sunshade curtain assembly 300, the reel 330 is installed between the first pulleys 30 of the two curtain body moving devices 310. One end of the curtain body 350 is fixedly connected to the reel 330, and the other end is fixedly connected to the pull rod. When the sunshade curtain assembly 300 works, the first pulley 30 in the curtain body moving device 310 rotates and drives the reel 330 to rotate, so as to realize that the curtain body moving device 310 drives the reel 330 to rotate. At the same time, the first pulley 30 rotates and drives the timing belt 70 to rotate. The timing belt 70 rotates and drives the pull rod to move. The pull rod moves and drives the curtain body 350 to move, so as to realize that the curtain body moving device 310 drives the curtain body 350 to move, thereby realizing that the curtain body moving device 310 drives the curtain body 350 to switch between the retracted state and the opened state.

[0074] Specifically, when the first pulley 30 rotates in the first direction (e.g., clockwise), the first pulley 30 drives the reel 330 to rotate in the first direction, and the first pulley 30 drives the synchronous belt 70 to rotate in the first direction. The synchronous belt 70 drives the curtain body 350 to move, so that the curtain body 350 switches from the retracted state to the opened state. At this time, the first belt body 71 on the upper side of the synchronous belt 70 is in a tensioned state, and the second belt body 73 on the lower side of the synchronous belt 70 is in a relaxed state.

[0075] When the first pulley 30 rotates in the opposite direction of the first direction (e.g., counterclockwise), the first pulley 30 drives the reel 330 to rotate in the opposite direction of the first direction, and the first pulley 30 drives the synchronous belt 70 to rotate in the opposite direction of the first direction. The synchronous belt 70 drives the curtain body 350 to move, so that the curtain body 350 switches from the opened state to the retracted state. At this time, the first belt body 71 on the upper side of the synchronous belt 70 is in a relaxed state, and the second belt body on the lower side of the synchronous belt 70 is in a tensioned state.

[0076] The applicant's research found that during the operation of the curtain body moving device 310, one side belt body of the synchronous belt 70 will always be in a relaxed state. The side belt body in the relaxed state will bend and arch, and the synchronous belt 70 will become loose, causing the side belt body in the relaxed state of the synchronous belt 70 to approach and easily come into contact with the side belt body in the tensioned state. As a result, the convex teeth of the side belt body in the relaxed state mesh with the convex teeth of the side belt body in the tensioned state, presenting a risk of gear biting, that is, the relative two side belt bodies of the synchronous belt 70 are prone to contact and interference. On the one hand, it will cause meshing abnormal noise of the synchronous belt 70, resulting in problems such as tooth skipping and climbing noise. On the other hand, it will cause an increase in the resistance of the synchronous belt 70 to rotate, thereby leading to an increase in the system resistance of the curtain body moving device 310, and further causing the curtain body moving device 310 to become stuck and the sunshade curtain assembly 300 to operate abnormally.

[0077] To solve the problem that one side belt body of the synchronous belt 70 will be in a relaxed state during the rotation process, the curtain body moving device 310 provided in the embodiment of the present application further includes a tensioning mechanism 90. The tensioning mechanism 90 is installed on the fixed seat 10. The tensioning mechanism 90 includes a first tensioning member 91 and a second tensioning member 93. The first tensioning member 91 abuts against the first belt body 71 of the synchronous belt 70, and the second tensioning member 93 abuts against the second belt body 73 of the synchronous belt 70.

[0078] In the embodiment of the present application, the first body 102 of the fixed seat 10 includes a first mounting member 21 and a second mounting member 23. The first mounting member 21 and the second mounting member 23 are arranged at intervals relative to each other. The first tensioning member 91 is mounted on the first mounting member 21, and the second tensioning member 93 is mounted on the second mounting member 23, so as to realize the installation of the tensioning mechanism 90 on the first body 102, and thus realize the installation of the tensioning mechanism 90 on the fixed seat 10. Among them, the tensioning mechanism 90 is arranged between the first pulley 30 and one end of the guide rail 106 close to the first pulley 30. Alternatively, in other embodiments, the tensioning mechanism 90 is arranged between the second pulley 50 and the other end of the guide rail 106 close to the second pulley 50.

[0079] In the embodiment of the present application, both the first tensioning member 91 and the second tensioning member 93 in the tensioning mechanism 90 include a holding portion 903. The holding portion 903 of the first tensioning member 91 abuts against the first belt body 71 of the synchronous belt 70, so as to realize that the first tensioning member 91 abuts against the first belt body 71. The holding portion 903 of the second tensioning member 93 abuts against the second belt body 73 of the synchronous belt 70, so as to realize that the second tensioning member 93 abuts against the second belt body 73. In this embodiment, the distance between the holding portion 903 of the first tensioning member 91 and the holding portion 903 of the second tensioning member 93 is less than the diameter of the first pulley 30. In some embodiments, the distance between the holding portion 903 of the first tensioning member 91 and the holding portion 903 of the second tensioning member 93 is less than the radius of the first pulley 30.

[0080] In the embodiment of the present application, by setting the first tensioning member 91 to abut against the first belt body 71 and the second tensioning member 93 to abut against the second belt body 73, the belt bodies on the upper and lower sides of the synchronous belt 70 can always be kept taut during operation, thus solving the problems that the synchronous belt 70 makes abnormal noises, generates skipping teeth and climbing noises, etc. due to the slack of one side of the belt body during the rotation of the synchronous belt 70, resulting in the loosening of the synchronous belt 70, and the problems that the rotation resistance of the synchronous belt 70 increases, the system resistance of the curtain moving device 310 increases, resulting in the jamming of the curtain moving device 310 and the abnormal operation of the sunshade curtain assembly 300.

[0081] The tensioning mechanism 90 may further include an elastic member 95. The elastic member 95 is connected to both the first tensioning member 91 and the second tensioning member 93, and the elastic member 95 is in a deformed state. The elastic deformation force generated when the elastic member 95 is in a deformed state is used to press the first tensioning member 91 against the first belt body 71 of the synchronous belt 70, and to press the second tensioning member 93 against the second belt body 73 of the synchronous belt 70, so as to make the first tensioning member 91 abut against the first belt body 71, and to make the second tensioning member 93 abut against the second belt body 73, thereby ensuring that the belt bodies on the upper and lower sides of the synchronous belt 70 can always be kept taut during rotation, solving the problem that one side of the belt body of the synchronous belt 70 may become loose during rotation, and at the same time, avoiding the problem that the tensioning pulley may become loose after long-term use when using the tensioning pulley to abut against the synchronous belt, resulting in low transmission efficiency of the synchronous belt 70. Exemplarily, the elastic force generated by the elastic member 95 includes tensile force and torsional force.

[0082] In addition, since the elastic member 95 has elasticity, the elastic member 95 can automatically adjust the elastic deformation force on the first tensioning member 91 and the second tensioning member 93 according to the loosening condition of the synchronous belt 70. While ensuring the tightness of the synchronous belt 70, it is not necessary for the staff to frequently adjust the tensioning mechanism 90, avoiding the problem that when using the tensioning pulley to tension the synchronous belt 70, it is necessary to manually adjust the position of the tensioning pulley to adjust the tightness of the synchronous belt 70, and at the same time avoiding the problem that as the synchronous belt 70 loosens, it is necessary to frequently adjust the position of the tensioning pulley, resulting in high maintenance costs, and also avoiding the problem that the tensioning pulley may become loose after long-term use when using the tensioning pulley to abut against the synchronous belt 70, resulting in low transmission efficiency of the synchronous belt 70. Exemplarily, the elastic force generated by the elastic member 95 includes tensile force and torsional force.

[0083] The structure and installation method of the tensioning mechanism 90 will be specifically described below in conjunction with specific embodiments.

[0084] Refer to Figure 5 , Figure 5 For Figure 4 the schematic structural diagram of the tensioning mechanism 90 in the curtain body moving device 310 shown.

[0085] In the curtain body moving device 310 of the first embodiment, the tensioning mechanism 90 includes a first tensioning member 91, a second tensioning member 93 and an elastic member 95. Both the first tensioning member 91 and the second tensioning member 93 are installed on the fixed seat 10, and the first tensioning member 91 and the second tensioning member 93 are arranged at intervals relative to each other, and the elastic member 95 is connected between the first tensioning member 91 and the second tensioning member 93.

[0086] Specifically, the first tensioning member 91 and the second tensioning member 93 each include a first mounting portion 901, a connecting arm 902, a supporting portion 903, a limiting portion 904, a second mounting portion 906, and an anti-slip portion 908. The connecting arm 902 is connected between the first mounting portion 901 and the supporting portion 903, so that the supporting portion 903 is connected to the first mounting portion 901. In this embodiment, the supporting portion 903 and the first mounting portion 901 are connected to opposite ends of the connecting arm 902 along the extension direction of the connecting arm 902, and the supporting portion 903 and the first mounting portion 901 are located at opposite sides of the connecting arm 902 along the thickness direction of the connecting arm 902. In this embodiment, the first mounting portion 901 and the supporting portion 903 are both cylindrical.

[0087] The limiting portion 904 is protruding from the peripheral side of the first mounting portion 901. In the present embodiment, there are two limiting portions 904, and the two limiting portions 904 are located on opposite sides of the first mounting portion 901. The second mounting portion 906 is connected to the connecting arm 902, and the second mounting portion 906 and the first mounting portion 901 are located on the same side of the connecting arm 902, and the second mounting portion 906 and the first mounting portion 901 are arranged at a relative interval. In the present embodiment, the second mounting portion 906 and the abutting portion 903 are connected to the same end of the connecting arm 902, and the second mounting portion 906 and the abutting portion 903 are located on opposite sides of the connecting arm 902 along the thickness direction of the connecting arm 902. The anti-slip portion 908 is connected to the end of the abutting portion 903 away from the connecting arm 902, and the anti-slip portion 908 protrudes relative to the peripheral side of the abutting portion 903.

[0088] The elastic member 95 is connected between the second mounting portion 906 of the first tensioning member 91 and the second mounting portion 906 of the second tensioning member 93, so as to realize that the elastic member 95 is connected between the first tensioning member 91 and the second tensioning member 93. In this embodiment, the elastic member 95 is a tension spring. The elastic member 95 includes a first end and a second end, and the first end and the second end are arranged oppositely along the extension direction of the elastic member 95, the first end is connected to the second mounting portion 906 of the first tensioning member 91, and the second end is connected to the second mounting portion 906 of the second tensioning member 93.

[0089] In this embodiment, the tensioning mechanism 90 further includes a first anti-slipping member 92 and a second anti-slipping member 94. The first anti-slipping member 92 is convexly arranged on the peripheral side of the second mounting portion 906 of the first tensioning member 91, and the first anti-slipping member 92 is located on the side where the first end of the elastic member 95 is away from the abutting portion 903 of the first tensioning member 91, so as to prevent the first end from slipping off the first tensioning member 91. The second anti-slipping member 94 is convexly arranged on the peripheral side of the second mounting portion 906 of the second tensioning member 93, and the second anti-slipping member 94 is located on the side where the second end of the elastic member 95 is away from the abutting portion 903 of the second tensioning member 93, so as to prevent the second end from slipping off the second tensioning member 93. It can be understood that the second mounting portion 906 of the first tensioning member 91 and the second mounting portion 906 of the second tensioning member 93 can also be provided with a limiting groove, and the opening of the limiting groove is provided on the peripheral surface of the second mounting portion 906. At this time, the first end of the elastic member 95 is located in the limiting groove of the first tensioning member 91, and the second end is located in the limiting groove of the second tensioning member 93, so as to prevent the first end of the elastic member 95 from sliding along the circumferential surface of the second mounting portion 906 of the first tensioning member 91, and prevent the second end from sliding along the circumferential surface of the second mounting portion 906 of the second tensioning member 93, thereby limiting the elastic member 95 in a fixed position and improving the installation stability of the tensioning mechanism 90.

[0090] Combined with reference Figure 4 , Figure 6 and Figure 7 , Figure 6 for Figure 3 The structure diagram of the curtain moving device 310 shown in FIG. 3 is another view from another perspective. Figure 7 for Figure 3 The structure diagram of the curtain moving device 310 shown in another viewing angle.

[0091] In the curtain moving device 310 of the first embodiment, the fixing seat 10 includes a first mounting member 21 and a second mounting member 23, and the first mounting member 21 and the second mounting member 23 are arranged at intervals. The first mounting member 21 is provided with a first mounting hole 11, and the second mounting member 23 is provided with a second mounting hole 13. In this embodiment, the first mounting hole 11 passes through the first mounting member 21, and the second mounting hole 13 passes through the second mounting member 23. In this embodiment, the first mounting hole 11 and the second mounting hole 13 both include a mounting hole portion 101 and an avoidance hole portion 103. The avoidance hole portion 103 surrounds the mounting hole portion 101, and the avoidance hole portion 103 is connected to the mounting hole portion 101. In this embodiment, there are two avoidance hole portions 103, and the two avoidance hole portions 103 are located on both sides of the mounting hole portion 101.

[0092] In the assembly structure of the tensioning mechanism 90 and the fixed seat 10, the first tensioning member 91 passes through the first mounting hole 11 of the fixed seat 10, the second tensioning member 93 passes through the second mounting hole 13, and the elastic member 95 is connected between the abutting portion 903 of the first tensioning member 91 and the abutting portion 903 of the second tensioning member 93. At this time, the deformation state of the elastic member 95 is a stretched state. Among them, the first mounting portion 901 of the first tensioning member 91 is mounted on the mounting hole portion 101 of the first mounting hole 11. The limiting portion 904 of the first tensioning member 91 is exposed relative to the first mounting hole 11, and the limiting portion 904 of the first tensioning member 91 abuts against the surface of the first mounting member 21 facing away from the synchronous belt 70 to limit the first tensioning member 91 in the first mounting hole 11 and prevent the first tensioning member 91 from detaching from the first mounting hole 11. The abutting portion 903 of the first tensioning member 91 abuts against the first abutting surface of the first belt body 71 in the synchronous belt 70. The anti-detachment portion 908 of the first tensioning member 91 is located on the side of the first belt body 71 facing away from the fixed seat 10 to prevent the first belt body 71 of the synchronous belt 70 from slipping off the abutting portion 903, improving the rotational stability of the synchronous belt 70.

[0093] The first mounting portion 901 of the second tensioning member 93 is mounted on the mounting hole portion 101 of the second mounting hole 13. The limiting portion 904 of the second tensioning member 93 is exposed relative to the second mounting hole 13, and the limiting portion 904 of the second tensioning member 93 abuts against the surface of the second mounting member 23 facing away from the synchronous belt 70 to prevent the second tensioning member 93 from detaching from the second mounting hole 13. The abutting portion 903 of the second tensioning member 93 abuts against the second abutting surface of the second belt body 73 in the synchronous belt 70. The anti-detachment portion 908 of the second tensioning member 93 is located on the side of the second belt body 73 facing away from the fixed seat 10 to prevent the second belt body 73 of the synchronous belt 70 from slipping off the abutting portion 903, improving the rotational stability of the synchronous belt 70.

[0094] During the assembly process of the tensioning mechanism 90 and the fixed seat 10, taking the installation of the first tensioning member 91 as an example, the first tensioning member 91 can be inserted into the first mounting hole 11. At this time, the first mounting portion 901 of the first tensioning member 91 passes through the mounting hole portion 101 of the first mounting hole 11, and the limiting portion 904 passes through the avoidance hole portion 103 and is exposed relative to the first mounting hole 11. Then, rotate the first tensioning member 91 so that the limiting portion 904 abuts against the surface of the first mounting member 21 in the fixed seat 10 facing away from the synchronous belt 70 to limit the first tensioning member 91 in the first mounting hole 11. At this time, the limiting portion 904 of the second tensioning member 93 abuts against the surface of the second mounting member 23 facing away from the synchronous belt 70.

[0095] In the curtain body moving device 310 provided by the first embodiment, by arranging an elastic member 95 to be connected between the first tensioning member 91 and the second tensioning member 93, so that the elastic member 95 generates tensile forces on both the first tensioning member 91 and the second tensioning member 93, thereby enabling the first tensioning member 91 and the second tensioning member 93 to always hold against the first belt body 71 and the second belt body 73 of the synchronous belt 70 respectively. The two side belt bodies of the synchronous belt 70 can always remain in a taut state during the rotation process, thus solving the problem that one side belt body of the synchronous belt 70 will become loose during the rotation process, and solving the problems such as abnormal noise, tooth skipping and climbing noise of the synchronous belt 70 caused by the looseness of one side belt body of the synchronous belt 70 during the rotation process, as well as the problem that the rotation resistance of the synchronous belt 70 increases, resulting in an increase in the system resistance of the curtain body moving device 310 and causing the curtain body moving device 310 to jam and the sunshade curtain assembly 300 to operate abnormally.

[0096] In addition, the tensioning mechanism 90 adopts a structure in which the elastic member 95 is assembled with the first tensioning member 91 and the second tensioning member 93. By utilizing the tensile elasticity of the elastic member 95, the tolerances and deformations existing in the first tensioning member 91 and the second tensioning member 93 themselves can be reduced. Also, without changing the installation positions of the first tensioning member 91 and the second tensioning member 93, the tensioning force on the synchronous belt 70 can be adjusted only by replacing the specification attributes of the elastic member 95 and the installation angles of the first tensioning member 91 and the second tensioning member 93, greatly reducing the manpower and difficulty required for installing the tensioning mechanism 90.

[0097] Furthermore, by arranging that the first mounting member 21 of the fixed seat 10 is provided with a first mounting hole 11, the second mounting member 23 is provided with a second mounting hole 13, and both the first tensioning member 91 and the second tensioning member 93 include a limiting portion 904. After the first tensioning member 91 and the second tensioning member 93 respectively pass through the first mounting hole 11 and the second mounting hole 13, the limiting portions 904 of the first tensioning member 91 and the second tensioning member 93 can respectively limit the first tensioning member 91 and the second tensioning member 93 in the first mounting hole 11 and the second mounting hole 13 of the fixed seat 10 by abutting against the first mounting member 21 and the second mounting member 23, avoiding the detachment of the tensioning mechanism 90 from the fixed seat 10, and at the same time being able to reduce the influence on other parts of the curtain body moving device 310 when adjusting the tensioning mechanism 90.

[0098] In addition, when using the method of pressing the synchronous belt with a tension pulley, installing the tension pulley requires removing the fixing seat 10 for installing the first pulley 30 and the second pulley 50, and then fixing the synchronous belt 70. Since the installation space of the curtain body moving device is usually limited, installing and replacing the synchronous belt 70 is relatively complex. Moreover, a certain tension force is required during the tensioning process of the synchronous belt 70, and direct manual operation cannot meet the requirement of the tension force. The process of tensioning and adjusting the synchronous belt 70 using the tension force is relatively complex and difficult. The tensioning mechanism 90 of this embodiment can be detachably installed on the fixing seat 10. On the one hand, it can be conveniently and quickly installed on the fixing seat 10 without removing the synchronous belt 70. On the other hand, when replacing the tensioning mechanism 90, it is not necessary to disassemble the entire fixing seat 10, reducing the difficulty of maintenance and replacement.

[0099] Refer to Figure 8 and Figure 9 , Figure 8 is Figure 1 a partial structural schematic diagram of the curtain body moving device 310 in the glass assembly 1 shown in Figure 9 is Figure 8 an exploded schematic diagram of the curtain body moving device 310 shown in

[0100] The difference between the curtain body moving device 310 in the second embodiment and the curtain body moving device 310 in the first embodiment is that the structure and installation method of the tensioning mechanism 90 of the curtain body moving device 310 in the second embodiment are different from those of the tensioning mechanism 90 of the curtain body moving device 310 in the first embodiment.

[0101] Specifically, in the curtain body moving device 310 of the second embodiment, the tensioning mechanism 90 includes a first tensioning member 91, a second tensioning member 93, and an elastic member 95. Among them, the elastic member 95 includes a first elastic part 97 and a second elastic part 99. Both the first elastic part 97 and the second elastic part 99 are installed on the fixing seat 10, and the first elastic part 97 and the second elastic part 99 are relatively spaced apart, and both the first elastic part 97 and the second elastic part 99 are in a deformed state. In this embodiment, the first elastic part 97 is installed in the first mounting hole 11 of the fixing seat 10, the second elastic part 99 is installed in the second mounting hole 13 of the fixing seat 10, and the second elastic part 99 is relatively spaced apart from the first elastic part 97. The first tensioning member 91 is fixedly connected to the first elastic part 97, and the second tensioning member 93 is fixedly connected to the second elastic part 99.

[0102] Combined with reference to Figure 10 , Figure 10 is Figure 9 an exploded mechanism schematic diagram of the tensioning mechanism 90 in the curtain body moving device 310 shown in

[0103] In this embodiment, the first tensioning member 91 and the second tensioning member 93 have substantially the same structure as the first tensioning member 91 and the second tensioning member 93 of the tensioning mechanism 90 in the curtain moving device 310 of the first embodiment. Specifically, the first tensioning member 91 and the second tensioning member 93 of this embodiment both include a first mounting portion 901, a connecting arm 902, a holding portion 903 and an anti-slip portion 908. The connection relationship and function of the first mounting portion 901, the connecting arm 902, the holding portion 903, the limiting portion 904 and the anti-slip portion 908 can be referred to the first tensioning member 91 and the second tensioning member 93 of the first embodiment, and will not be described in detail here.

[0104] In this embodiment, the first tensioning member 91 and the second tensioning member 93 further include a fixing portion 905, which is convexly disposed on the circumference of the first mounting portion 901. In this embodiment, the first tensioning member 91 and the second tensioning member 93 are further provided with a clamping groove 909, the opening of which is disposed on the end surface of the first mounting portion 901 away from the connecting arm 902, and the clamping groove 909 penetrates the circumference of the first mounting portion 901.

[0105] The first elastic part 97 and the second elastic part 99 each include a torsion portion 981, a first connection end 983 and a second connection end 985, and the first connection end 983 and the second connection end 985 are connected to opposite ends of the torsion portion 981 along the extension direction. In this embodiment, the first elastic part 97 and the second elastic part 99 are both torsion springs.

[0106] The following is a detailed description of the manner in which the tensioning mechanism 90 of this embodiment is installed on the fixing seat 10 .

[0107] Combined with reference Figure 9 , Figure 11 and Figure 12 , Figure 11 for Figure 10 The schematic diagram of the assembly structure of the first elastic part 97 and the first tensioning member 91 in the tensioning mechanism 90 is shown. Figure 12 for Figure 10 The first elastic part 97 and the first tensioning member 91 of the tensioning mechanism 90 are shown as a schematic diagram of the structure installed on the fixing seat 10. Figure 12 The second fixing hole is not shown in the perspective view.

[0108] In this embodiment, the first mounting member 21 in the fixing seat 10 is further provided with a first fixing hole 18, and the opening of the first fixing hole 18 is provided on the inner wall of the first mounting hole 11. The second mounting member 23 is further provided with a second fixing hole, and the opening of the second fixing hole is provided on the inner wall of the second mounting hole 13. In this embodiment, the first fixing hole 18 and the second fixing hole are through holes, the first fixing hole 18 penetrates the inner wall of the first mounting hole 11, and the second fixing hole penetrates the inner wall of the second mounting hole 13.

[0109] In the assembly structure of the first elastic part 97, the first tensioning part 91 and the fixed seat 10, the first elastic part 97 is installed in the first installation hole 11 of the fixed seat 10. Among them, the torsion part 981 of the first elastic part 97 is sleeved on the periphery of the first installation part 901 of the first tensioning part 91. The torsion part 981 abuts against the fixed part 905 of the first tensioning part 91, and the torsion part 981 is located in the first installation hole 11. The first connection end 983 is clamped in the first fixing hole 18 to realize the fixed connection of the first connection end 983 of the first elastic part 97 to the first installation part fixed seat 10. The second connection end 985 is clamped in the clamping groove 909 of the first tensioning part 91 to realize the fixed connection of the first tensioning part 91 to the second connection end 985 of the first elastic part 97, so as to realize the fixed connection between the first tensioning part 91 and the first elastic part 97. At this time, the fixed part 905 of the first tensioning part 91 is used to prevent the first elastic part 97 from moving, thereby improving the installation stability of the first elastic part 97.

[0110] Continue to refer to Figures 8 to 10 , the assembly method of the second elastic part 99, the second tensioning part 93 and the fixed seat 10 is the same as that of the first elastic part 97, the first tensioning part 91 and the fixed seat 10. Specifically, the second elastic part 99 is installed in the second installation hole 13 of the fixed seat 10. Among them, the torsion part 981 of the second elastic part 99 is sleeved on the periphery of the first installation part 901 of the second tensioning part 93, and the torsion part 981 of the second elastic part 99 abuts against the fixed part 905 of the second tensioning part 93. The first connection end 983 is clamped in the second fixing hole to realize the fixed connection of the first connection end 983 of the second elastic part 99 to the fixed seat 10. The second connection end 985 is clamped in the clamping groove 909 of the second tensioning part 93 to realize the fixed connection of the second tensioning part 93 to the second connection end 985 of the second elastic part 99, so as to realize the fixed connection between the second tensioning part 93 and the second elastic part 99. At this time, the fixed part 905 of the second tensioning part 93 is used to prevent the second elastic part 99 from moving, thereby improving the installation stability of the second elastic part 99.

[0111] Among them, the torsion portions 981 of the first elastic part 97 and the second elastic part 99 are both in a deformed state, and the deformed state is a torsional state. Specifically, compared with the first elastic part 97 in the natural state, after assembling the first elastic part 97 with the fixed seat 10 and the first tensioning member 91, the second connection end 985 in the first elastic part 97 is twisted relative to the first connection end 983, so that the torsion portion 981 of the first elastic part 97 is in a torsional state and generates a torsional force to press the first tensioning member 91 against the first belt body 71 of the synchronous belt 70, thereby realizing that the abutting portion 903 of the first tensioning member 91 abuts against the first belt body 71 of the synchronous belt 70. Compared with the second elastic part 99 in the natural state, after assembling the second elastic part 99 with the fixed seat 10 and the second tensioning member 93, the second connection end 985 in the first elastic part 97 is twisted relative to the first connection end 983, so that the torsion portion 981 of the second elastic part 99 is in a torsional state and generates a torsional force to press the second tensioning member 93 against the second belt body 73 of the synchronous belt 70, thereby realizing that the abutting portion 903 of the second tensioning member 93 abuts against the second belt body 73 of the synchronous belt 70, so that both belt bodies of the synchronous belt 70 are always in a taut state during rotation.

[0112] In the tensioning mechanism 90 provided by the embodiment of the present application, by setting the elastic member 95 to include a first elastic part 97 and a second elastic part 99, setting the first tensioning member 91 to be fixedly connected to the first elastic part 97, and setting the second tensioning member 93 to be fixedly connected to the second elastic part 99, it is realized that the first tensioning member 91 is pressed against the first belt body 71 of the synchronous belt 70 by using the elastic force generated by the first elastic part 97, and the second tensioning member 93 is pressed against the second belt body 73 of the synchronous belt 70 by using the elastic force generated by the second elastic part 99, so that both belt bodies on both sides of the synchronous belt 70 are always in a taut state during rotation, solving the problems that the synchronous belt 70 makes abnormal noises, generates problems such as tooth skipping and climbing noises due to the slack of one belt body during the rotation of the synchronous belt 70, and the increased rotational resistance of the synchronous belt 70, resulting in an increase in the system resistance of the curtain moving device 310 and causing the curtain moving device 310 to jam and the sunshade curtain assembly 300 to operate abnormally.

[0113] Specifically, in the second embodiment, the torsion portion 981 of the first elastic portion 97 is in a deformed state to generate a torsional force on the first tensioning member 91, thereby pressing the first tensioning member 91 against the first belt body 71 of the synchronous belt 70, and further realizing the abutment of the first tensioning member 91 against the first belt body 71 of the synchronous belt 70. The torsion portion 981 of the second elastic portion 99 is in a deformed state to generate a torsional force on the second tensioning member 93, thereby pressing the second tensioning member 93 against the second belt body 73 of the synchronous belt 70, and further realizing the abutment of the second tensioning member 93 against the second belt body 73 of the synchronous belt 70, and further realizing that the belt bodies on both sides of the synchronous belt 70 are always in a taut state during rotation.

[0114] In addition, by arranging the first elastic portion 97 and the second elastic portion 99 of the elastic member 95 to be respectively installed in the first mounting hole 11 and the second mounting hole 13, the tensioning mechanism 90 can be detachably installed on the fixing seat 10. The tensioning mechanism 90 can be replaced without removing the fixing seat 10, and by using the first elastic portion 97 and the second elastic portion 99 with different properties, and adjusting the mounting angles of the first tensioning member 91 and the second tensioning member 93, the magnitude of the abutting force applied to the synchronous belt 70 can be adjusted, thereby realizing the adjustment of the tensioning force of the synchronous belt 70. In addition, the first elastic portion 97 and the second elastic portion 99 in the elastic member 95 are arranged at intervals and do not affect each other. When maintenance and replacement are required, the first elastic portion 97 or the second elastic portion 99 can be separately removed, saving the cost of maintenance and replacement.

[0115] Refer to Figure 13 、 Figure 14 and Figure 15 , Figure 13 is Figure 1 a partial structural schematic diagram of the curtain body moving device 310 in the third embodiment in the glass assembly 1 shown in Figure 14 is Figure 13 an exploded structural schematic diagram of the curtain body moving device 310 shown in Figure 15 is Figure 14 an exploded structural schematic diagram of the tensioning mechanism 90 in the curtain body moving device 310 shown in

[0116] The difference between the curtain body moving device 310 in the third embodiment and the curtain body moving device 310 in the second embodiment is that in the tensioning mechanism 90 of the curtain body moving device 310 in the third embodiment, the elastic member 95 further includes a connecting portion 98, and the connecting portion 98 is connected between the first elastic portion 97 and the second elastic portion 99.

[0117] Specifically, in the tensioning mechanism 90 of the curtain body moving device 310 of the third embodiment, both the first tensioning member 91 and the second tensioning member 93 are provided with connection holes 907 for connecting with the elastic member 95. In this embodiment, the connection hole 907 of the first tensioning member 91 penetrates the first tensioning member 91 along the extending direction of the first tensioning member 91, and the connection hole 907 of the second tensioning member 93 penetrates the second tensioning member 93 along the extending direction of the second tensioning member 93. In this embodiment, both the first tensioning member 91 and the second tensioning member 93 are cylinders.

[0118] The elastic member 95 includes a first elastic portion 97, a second elastic portion 99, and a connecting portion 98. Both the first elastic portion 97 and the second elastic portion 99 are installed on the fixed seat 10, and the first elastic portion 97 and the second elastic portion 99 are relatively spaced apart. Among them, both the first elastic portion 97 and the second elastic portion 99 include a torsion portion 981, a first connection end 983, and a second connection end 985. The first connection end 983 and the second connection end 985 are connected to opposite ends of the torsion portion 981 along the extending direction. The connecting portion 98 is connected between the first connection end 983 of the first elastic portion 97 and the first connection end 983 of the second elastic portion 99, so as to realize that the connecting portion 98 is connected between the first elastic portion 97 and the second elastic portion 99.

[0119] In the assembled tensioning mechanism 90, the second connection end 985 of the first elastic portion 97 in the elastic member 95 is fixedly connected to the connection hole 907 of the first tensioning member 91, so as to realize the fixed connection between the first tensioning member 91 and the first elastic portion 97. The second connection end 985 of the second elastic portion 99 is fixedly connected to the connection hole 907 of the second tensioning member 93, so as to realize the fixed connection between the second tensioning member 93 and the second elastic portion 99, thereby realizing the connection of the elastic member 95 with both the first tensioning member 91 and the second tensioning member 93. In this embodiment, the first tensioning member 91 and the second tensioning member 93 are injection molding sleeves, the elastic member 95 is a torsion spring, the first elastic portion 97, the second elastic portion 99, and the connecting portion 98 are integrally formed, and the elastic member 95 and the first tensioning member 91 and the second tensioning member 93 are integrally formed by injection molding.

[0120] Refer to Figure 16 and Figure 17 , Figure 16 is Figure 13 a schematic structural diagram of the curtain body moving device 310 shown in another perspective, Figure 17 is Figure 16 a schematic structural diagram of part A in the curtain body moving device 310 shown. Among them Figure 16 and Figure 17 the dashed lines in indicate the positions of the tensioning mechanism 90 in the natural state after being installed on the fixed seat 10.

[0121] In the assembly structure of the tensioning mechanism 90 and the fixed seat 10, the fixed seat 10 includes a first mounting member 21 and a second mounting member 23, and the second mounting member 23 and the first mounting member 21 are arranged at intervals. In this embodiment, both the first mounting member 21 and the second mounting member 23 are fixed columns. The torsion portion 981 of the first elastic portion 97 of the elastic member 95 is sleeved on the outer side of the first mounting member 21, so as to install the torsion portion 981 of the first elastic portion 97 on the first mounting member 21 of the fixed seat 10, thereby installing the first elastic portion 97 on the fixed seat 10. The torsion portion 981 of the second elastic portion 99 is sleeved on the outer side of the second mounting member 23, so as to install the torsion portion 981 of the second elastic portion 99 on the second mounting member 23 of the fixed seat 10, and is arranged at intervals relative to the torsion portion 981 of the first elastic portion 99, thereby installing the second elastic portion 99 on the fixed seat 10, and further installing the elastic member 95 on the fixed seat 10, and further installing the tensioning mechanism 90 on the fixed seat 10.

[0122] Wherein, in order to prevent the tensioning mechanism 90 from detaching from the fixed seat 10 during the operation of the curtain body moving device 310, the first seat body 102 of the fixed seat 10 further includes a clamping member 19, and the clamping member 19 is used for clamping with the connecting portion 98 of the elastic member 95 to limit the elastic member 95 on the fixed seat 10, thereby limiting the tensioning mechanism 90 on the fixed seat 10 and preventing the tensioning mechanism 90 from detaching from the fixed seat 10 during the rotation of the synchronous belt 70.

[0123] Refer to in combination Figure 18 , Figure 18 For Figure 16 the structural schematic diagram of the curtain body moving device 310 shown in other perspectives. Specifically, the clamping member 19 includes a first clamping portion 191 and a second clamping portion 193, and the first clamping portion 191 and the second clamping portion 193 are arranged at intervals. In this embodiment, the first clamping portion 191 is provided with a clamping hole 190, and the clamping hole 190 penetrates through the first clamping portion 191. In this embodiment, the opening of the clamping hole 190 is arranged on the surface of the first clamping portion 191 facing the second clamping portion 193, and the clamping hole 190 penetrates through the two end faces of the first clamping portion 191 along the extending direction of the first clamping portion 191. There are two second clamping portions 193, and the two second clamping portions 193 are arranged at intervals. The connecting portion 98 of the elastic member 95 is located between the first clamping portion 191 and the second clamping portion 193, and the connecting portion 98 is clamped in the clamping hole 190 to realize the clamping of the connecting portion 98 with the first clamping portion 191, thereby realizing the clamping of the clamping member 19 with the connecting portion 98, and further realizing the limitation of the tensioning mechanism 90 on the fixed seat 10, avoiding the risk that the tensioning mechanism 90 detaches from the fixed seat during the operation of the curtain body moving device 310.

[0124] When installing the tensioning mechanism 90, first pinch the synchronous belt 70, place the first tensioning member 91 and the second tensioning member 93 in the tensioning mechanism 90 on the opposite sides of the synchronous belt 70 respectively, and then push the torsion portions 981 of the first elastic part 97 and the second elastic part 99 of the elastic member 95 into the first mounting member 21 and the second mounting member 23 of the fixed seat 10 respectively. When the connecting part 98 of the elastic member 95 is completely snapped into the snap hole 190 of the snap member 19, the installation of the tensioning mechanism 90 is completed. When it is necessary to replace the tensioning mechanism 90, similarly, only need to pinch the synchronous belt 70 tightly and take out the tensioning mechanism 90 from the first mounting member 21 and the second mounting member 23 of the fixed seat 10.

[0125] Continue to refer to Figure 17 , in which after the synchronous belt 70 is removed and the tensioning mechanism 90 is in the natural state, the first tensioning member 91 and the second tensioning member 93 of the tensioning mechanism 90 are located at Figure 17 the position of the dashed line in. After the tensioning mechanism 90 is installed on the fixed seat 10, the first tensioning member 91 and the second tensioning member 93 move to the position of the solid line. Compared with the tensioning mechanism 90 in the natural state, the first tensioning member 91 moves upward, and the first tensioning member 91 moves and drives the second connecting end 985 of the first elastic part 97 of the elastic member 95 to twist relative to the first connecting end 983, so that the torsion portion 981 of the first elastic part 97 of the elastic member 95 is in a deformed state and generates a torsion force to press the first tensioning member 91 against the first belt body 71 of the synchronous belt 70. The second tensioning member 93 moves downward, and the second tensioning member 93 moves and drives the second connecting end 985 of the second elastic part 99 of the elastic member 95 to twist relative to the first connecting end 983, so that the torsion portion 981 of the second elastic part 99 of the elastic member 95 is in a deformed state and generates a torsion force to press the second tensioning member 93 against the second belt body 73 of the synchronous belt 70, thereby realizing that the first tensioning member 91 and the second tensioning member 93 abut against the synchronous belt 70, and further realizing that the two side belt bodies of the synchronous belt 70 are always in a taut state during the rotation process.

[0126] In the tensioning mechanism 90 provided by the third embodiment, by setting the elastic member 95 to include a connecting portion 98, the connecting portion 98 is used to connect between the first connecting end 983 of the first elastic portion 97 and the first connecting end 983 of the second elastic portion 99, so that the first connecting end 983 of the first elastic portion 97 and the first connecting end 983 of the second elastic portion 99 remain fixed. At this time, by adjusting the positions of the first tensioning member 91 and the second tensioning member 93, the second connecting end 985 of the first elastic portion 97 can be driven to twist relative to the first connecting end 983 of the first elastic portion 97, and the second connecting end 985 of the second elastic portion 99 can be driven to twist relative to the first connecting end 983 of the second elastic portion 99, so as to realize that the torsion portions 981 of both the first elastic portion 97 and the second elastic portion 99 are in a deformed state. The torsion portion 981 of the first elastic portion 97 generates a torsion force on the first tensioning member 91 to press the first tensioning member 91 against the first belt body 71 of the synchronous belt 70, so as to realize the abutment of the first tensioning member 91 and the first belt body 71 of the synchronous belt 70. The torsion portion 981 of the second elastic portion 99 generates a torsion force on the second tensioning member 93 to press the second tensioning member 93 against the second belt body 73 of the synchronous belt 70, so as to realize the abutment of the second tensioning member 93 and the second belt body 73 of the synchronous belt 70. Furthermore, it is realized that the belt bodies on both sides of the synchronous belt 70 are always in a taut state during rotation, solving the problems such as abnormal noise of the synchronous belt 70 caused by the slack of one side belt body during the rotation of the synchronous belt 70, skipping teeth and climbing noise, and the increase in the rotation resistance of the synchronous belt 70, resulting in an increase in the system resistance of the curtain moving device 310 and causing the curtain moving device 310 to jam and the sunshade curtain assembly 300 to operate abnormally.

[0127] In addition, in the tensioning mechanism 90 of this embodiment, by setting the torsion portion 981 of the first elastic portion 97 of the elastic member 95 to be sleeved outside the first mounting member 21 of the fixed seat 10, and the torsion portion 981 of the second elastic portion 99 to be sleeved outside the second mounting member 23, the elastic member 95 can be detachably mounted on the fixed seat 10, so as to realize that the tensioning mechanism 90 is detachably mounted on the fixed seat 10. On the one hand, the tensioning mechanism 90 can be conveniently and quickly mounted on the fixed seat 10 without removing the synchronous belt 70. On the other hand, when replacing the tensioning mechanism 90, it is not necessary to disassemble the entire fixed seat 10, reducing the difficulty of maintenance and replacement.
