Abstract
Description
Technical Field
[0001] This invention relates to the field of window technology for vehicles, specifically to a sunroof movement system, a sunroof, and an automobile. Background Technology
[0002] A car sunroof, installed on the roof, can effectively circulate air inside the vehicle, increasing the intake of fresh air. At the same time, a car sunroof can also broaden the field of vision and meet the needs of mobile photography and videography, greatly enhancing the passenger's driving experience.
[0003] Car sunroofs are opened or closed via a motion system. This system typically includes a sunroof sliding glass assembly, guide rails, a motor, a flexible shaft, and a mechanical assembly. The motor drives the mechanical assembly through the flexible shaft to move within the guide rails, and the sunroof sliding glass assembly, mounted on the mechanical assembly, moves accordingly. Existing sunroof motion systems suffer from complex structures and numerous components, resulting in low stability of the connection and movement, as well as complex and inefficient assembly and disassembly processes. Summary of the Invention
[0004] One objective of this invention is to provide a sunroof movement system to solve the problems of complex structure and numerous components in existing sunroof movement systems; another objective is to provide a sunroof; and a third objective is to provide an automobile.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A sunroof movement system includes a glass connector, a front lift arm, a slider, a rear lift arm, a guide rail, and a drive mechanism. The slider is disposed within the guide rail. The glass connector, the front lift arm, the slider, the rear lift arm, and the glass connector are sequentially connected to form a four-bar linkage. The drive mechanism is connected to the slider and drives the slider to move within the guide rail, causing the glass connector to rise, fall, or translate. The guide rail has a guide groove, and the front lift arm has a first front pin located within the guide groove. When the front lift arm moves with the slider, the first front pin moves within the guide groove to limit the position of the glass connector.
[0007] According to the above technical means, when the driving mechanism drives the slider to move within the guide rail, the movement characteristics of the four-bar linkage can raise or lower the glass connector. The slider's movement also drives the front lifting arm, the rear lifting arm, and the glass connector to translate. Because the first front pin moves within the guide rail guide groove as the front lifting arm moves with the slider to limit the position of the glass connector, the guide rail simultaneously guides the slider and limits the position of the glass connector via the first front pin and the guide rail guide groove. Furthermore, with fewer components limiting the slider's movement, the slider will not experience jamming or other problems. The slider can be designed as a single structural component and has good motion stability. The sunroof movement system includes a glass connector, front lifting arm, slider, rear lifting arm, guide rail, and driving mechanism, with relatively few components. The sunroof movement system has a simple structure, simple assembly and disassembly process, and high assembly and disassembly efficiency, thus offering the advantage of low cost.
[0008] Furthermore, the front lifting arm includes a front lifting arm connector and a front lifting arm slider. The rear end of the front lifting arm connector is fixedly connected to the front side of the glass connector, the front end of the front lifting arm connector is hinged to the front lifting arm slider, and the front lifting arm slider is slidably connected to the slider.
[0009] Based on the above technical means, two of the movable positions in the four-bar linkage can be realized, and both of these movable positions are located at the front lifting arm. The glass connector only needs to be provided with a structure that connects to the front lifting arm connector, which can reduce the structural complexity of the glass connector. The glass connector is fixedly connected to the front lifting arm connector and has a large contact area, which can reduce stress concentration. The glass connector does not need to be provided with a reinforcing structure such as a reinforcing member, thereby achieving the purpose of cost reduction.
[0010] Furthermore, the front lifting arm slider is provided with a front through groove, one side of the front lifting arm slider is provided with a first front pin, and the other side of the front lifting arm slider is provided with a second front pin; the slider is provided with a first guide groove and a slider limiting block; the second front pin is provided in the first guide groove, and the slider limiting block is provided in the front through groove.
[0011] Based on the aforementioned technical means, the movement trajectory of the front lifting arm slider can be restricted. Since the hinge joint between the front lifting arm connector and the front lifting arm slider, as well as the connection between the front lifting arm slider and the slider, are two of the movable positions in the four-bar linkage, the movement trajectory of the front lifting arm slider can determine the movement trajectory of the front lifting arm connector and the glass connector, thereby achieving the lifting of the glass connector.
[0012] Furthermore, the front through groove is an arc-shaped through groove arranged along the moving direction of the slider, and both ends of the front through groove are curved upwards.
[0013] Based on the above technical means, the movement trajectory of the slider limit block can be restricted, thereby enabling the slider to move along the set trajectory, and the glass connector can be raised or lowered.
[0014] Furthermore, the first guide groove is located on the lower side of the slider limiting block.
[0015] According to the above technical means, the first guide groove and the slider limiting block can jointly restrict the movement trajectory of the front lifting arm, thereby enabling the front lifting arm to move according to the set trajectory, so that the glass connector can be raised, lowered or translated.
[0016] Furthermore, the first guide groove is arranged along the moving direction of the slider, and the front end of the first guide groove is curved upward.
[0017] According to the above technical means, the movement trajectory of the second front pin can be restricted, thereby causing the slider to move along the set trajectory, so that the glass connector can be raised or lowered at the front end of the first guide groove.
[0018] Furthermore, the rear lifting arm includes a rear lifting arm connector and a rear lifting arm slider. The front end of the rear lifting arm connector is fixedly connected to the rear side of the glass connector, the rear end of the rear lifting arm connector is hinged to the rear lifting arm slider, and the rear lifting arm slider is slidably connected to the slider.
[0019] Based on the above technical means, the movable positions of the other two links in the four-bar linkage can be realized, and both movable positions are located at the rear lifting arm. The glass connector only needs to be set with a structure that connects to the rear lifting arm connector, which can reduce the structural complexity of the glass connector. The glass connector is fixedly connected to the rear lifting arm connector and has a large contact area, which can reduce stress concentration. The glass connector does not need to be equipped with a reinforcing structure such as a reinforcing member, thereby achieving the purpose of cost reduction.
[0020] Furthermore, the rear lifting arm slider is provided with a first rear pin and a second rear pin on one side; the slider is provided with a second guide groove; the first rear pin and the second rear pin are both located in the second guide groove.
[0021] Based on the aforementioned technical means, the movement trajectory of the rear lifting arm slider can be restricted. Since the hinge joint between the rear lifting arm connector and the rear lifting arm slider, as well as the connection between the rear lifting arm slider and the slider, are two other movable positions in the four-bar linkage, the movement trajectory of the rear lifting arm slider can determine the movement trajectory of the rear lifting arm connector and the glass connector, thereby realizing the lifting or lowering of the glass connector.
[0022] Furthermore, the second guide groove is arranged along the moving direction of the slider, and the second guide groove includes, from back to front, a first horizontal section, a first upward tilting section, a second horizontal section, a second upward tilting section, a top end, a first downward tilting section, a third horizontal section, a second downward tilting section, and a fourth horizontal section.
[0023] According to the above-mentioned technical means, the movement trajectory of the first rear pin and the second rear pin can be restricted, thereby restricting the movement trajectory of the rear lifting arm sliding member, so that the glass connector can be raised or lowered.
[0024] Furthermore, the guide rail guide groove is provided along the moving direction of the slider, and the guide rail guide groove includes an arc segment and a downward sloping segment located at the front end of the arc segment.
[0025] According to the above-mentioned technical means, the movement trajectory of the first front pin can be restricted, thereby restricting the movement trajectory of the front lifting arm slider, as well as the movement trajectory of the front lifting arm connector and the glass connector, so as to realize the lifting or lowering of the glass connector.
[0026] Furthermore, the lower end of the slider away from the glass connector is provided with an outwardly flared portion protruding from the surface of the slider, and the outer surface of the outwardly flared portion is adapted to contact the guide rail.
[0027] According to the above-mentioned technical means, the outer surface of the expanded portion is suitable for contacting the guide rail. The lower end of the slider contacts the guide rail through the outer surface of the expanded portion, which can reduce the contact area between the slider and the guide rail, thereby reducing the frictional force between the slider and the guide rail. The drive mechanism can drive the slider to move within the guide rail with low power output.
[0028] Furthermore, a shock-absorbing plate is provided in the middle of the outer expansion portion.
[0029] Based on the aforementioned technical means, the damping pad can play a role in damping vibration and reduce the noise during the operation of the sunroof movement system.
[0030] A sunroof includes a glass assembly and the aforementioned sunroof movement system, wherein the left and right sides of the glass assembly are respectively connected to the sunroof movement system.
[0031] Because the sunroof motion system has the advantages of simple structure, simple disassembly and assembly process, high disassembly and assembly efficiency, and good motion stability, the sunroof has high motion stability and low noise, which can improve the user experience.
[0032] An automobile includes a vehicle body, the upper part of which is provided with the aforementioned sunroof.
[0033] The beneficial effects of this invention are:
[0034] In the sunroof movement system of the present invention, when the driving mechanism drives the slider to move within the guide rail, the glass connector can be raised or lowered due to the motion characteristics of the four-bar linkage. The slider's movement also drives the front lift arm, the rear lift arm, and the glass connector to translate. The guide rail simultaneously guides the slider and restricts the position of the glass connector via the first front pin and the guide rail guide groove. Using only the guide rail as a single component to simultaneously restrict the movement of the slider and the four-bar linkage, and with fewer components restricting the slider's movement, problems such as slider jamming are avoided. This allows the slider to be designed as a single structural component, and the sunroof movement system exhibits good motion stability, with smoother raising, lowering, or translating of the glass connector and lower noise. The sunroof movement system includes a glass connector, a front lift arm, a slider, a rear lift arm, a guide rail, and a driving mechanism. With relatively few components and a simple structure, it has the advantage of low cost. Attached Figure Description

[0060] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0061] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0062] This embodiment proposes a sunroof movement system for driving the sunroof glass 11 to move. In practical applications, two sunroof movement systems are located on the left and right sides of the sunroof glass 11 respectively and connected to the sunroof glass 11, jointly driving the sunroof glass 11 to move. Here, the left and right sides refer to the left and right sides relative to the vehicle's forward direction. (Refer to...) Figure 1 As shown, the sunroof movement system includes a glass connector 10, a front lift arm 20, a slider 40, a rear lift arm 30, a guide rail 50, and a drive mechanism.
[0063] The glass connector 10 is used to connect with the sunroof glass 11, and serves to fix and protect the sunroof glass 11.
[0064] In one embodiment, the glass assembly 60 includes a sunroof glass 11 and a glass connector 10, the glass connector 10 covering the outer periphery of the sunroof glass 11, the glass connector 10 being used to connect to two front lift arms 20 on the left and right sides, and two rear lift arms 30 on the left and right sides.
[0065] The glass connector 10, front lifting arm 20, slider 40, and rear lifting arm 30 are connected to form a four-bar linkage. The drive mechanism is connected to the slider 40 and drives the slider 40 to move within the guide rail 50. According to the motion principle of the four-bar linkage, when the slider 40 moves, it can cause the front lifting arm 20 and the rear lifting arm 30 to move, thereby raising or lowering the glass connector 10.
[0066] The guide rail 50 is provided with a guide rail guide groove 51 and a guide rail limiting groove. The guide rail guide groove 51 is provided on the guide rail wall of the guide rail 50, and the guide rail guide groove 51 is arranged along the moving direction of the slider 40. Figure 3 and Figure 4As shown, the front lift arm 20 is provided with a first front pin 24, which is located in the guide groove 51 of the guide rail. When the front lift arm 20 moves with the slider 40, the first front pin 24 moves within the guide groove 51 of the guide rail to limit the position of the glass connector 10. The slider 40 is located in the guide rail limiting groove. When the drive mechanism drives the slider 40 to move within the guide rail 50, the slider 40 can also drive the front lift arm 20 and the rear lift arm 30 to move, so that the glass connector 10 can be translated. The direction of movement is along the front-rear direction of the vehicle.
[0067] In this embodiment of the sunroof movement system, the glass connector 10, the front lifting arm 20, the slider 40, the rear lifting arm 30, and the glass connector 10 are sequentially connected to form a four-bar linkage. When the drive mechanism drives the slider 40 to move within the guide rail 50, the movement characteristics of the four-bar linkage allow the glass connector 10 to rise or fall. The movement of the slider 40 also causes the front lifting arm 20, the rear lifting arm 30, and the glass connector 10 to translate. Because the first front pin 24 moves within the guide rail guide groove 51 as the front lifting arm 20 moves with the slider 40 to restrict the position of the glass connector 10, and the guide rail 50 simultaneously guides the slider 40 and restricts the position of the glass connector 10 through the first front pin 24 and the guide rail guide groove 51, the number of components in the sunroof movement system can be relatively reduced, resulting in a simpler structure, simpler assembly and disassembly processes, and higher assembly and disassembly efficiency. Furthermore, with fewer components restricting the movement of the slider 40, the slider 40 will not experience jamming or other problems, and the slider 40 can be designed as a single integrated component. In summary, the sunroof motion system has the advantages of low cost and good motion stability.
[0068] In one embodiment of this application, as Figure 3 , Figure 4 and Figure 11 As shown, the front lift arm 20 includes a front lift arm connector 21 and a front lift arm slider 22. The rear end of the front lift arm connector 21 is fixedly connected to the front side of the glass connector 10, and the front end of the front lift arm connector 21 is hinged to the front lift arm slider 22 via a front pin 26. The front lift arm slider 22 is slidably connected to the slider 40. The rear end and front end are relative to the longitudinal direction of the vehicle, with the front end of the front lift arm connector 21 located in front of the rear end of the front lift arm connector 21.
[0069] In one embodiment of this application, as Figure 7 , Figure 8 and Figure 11As shown, the rear lift arm 30 includes a rear lift arm connector 31 and a rear lift arm slider 32. The front end of the rear lift arm connector 31 is fixedly connected to the rear side of the glass connector 10, and the rear end of the rear lift arm connector 31 is hinged to the rear lift arm slider 32 via a rear pin 35. The rear lift arm slider 32 is slidably connected to the slider 40. The rear end and front end are relative to the front-rear direction of the vehicle, with the front end of the rear lift arm connector 31 located in front of the rear end of the rear lift arm connector 31.
[0070] In the above embodiment, the glass connector 10, the front lifting arm 20, the slider 40, the rear lifting arm 30, and the glass connector 10 are sequentially connected to form a four-bar linkage. The four movable positions of the four-bar linkage are: the hinge point between the front lifting arm connector 21 and the front lifting arm slider 22; the hinge point between the rear lifting arm connector 31 and the rear lifting arm slider 32; the connection point between the front lifting arm slider 22 and the slider 40; and the connection point between the rear lifting arm slider 32 and the slider 40. The glass connector only needs to have structures for connecting to the front lifting arm connector and the rear lifting arm connector, which reduces the structural complexity of the glass connector. The glass connector is fixedly connected to the front lifting arm connector and has a large contact area, and the glass connector is fixedly connected to the rear lifting arm connector and has a large contact area, which reduces stress concentration. The glass connector does not need to have reinforcing structures such as reinforcing members for connecting the glass connector, the front lifting arm connector, and the rear lifting arm connector, thereby achieving cost reduction. Furthermore, the glass connector can meet the strength requirements during use.
[0071] Among them, such as Figure 2 and Figure 3 As shown, the connection method between the front lifting arm connector 21 and the front mounting bracket 12 is further as follows: Figure 2 and Figure 7 As shown, the connection method between the rear lift arm connector 31 and the rear mounting bracket 13 can be configured according to usage requirements. For example, bolts or other fasteners 80 can be used to fix the front lift arm connector 21 and the front mounting bracket 12 by passing through the mounting holes on the front lift arm connector 21 and the front mounting bracket 12, and bolts or other fasteners 80 can be used to fix the rear lift arm connector 31 and the rear mounting bracket 13 by passing through the mounting holes on the rear lift arm connector 31 and the rear mounting bracket 13.
[0072] In another embodiment of this application, the front side of the glass connector 10 is hinged to the front lifting arm 20, and the rear side of the glass connector 10 is hinged to the rear lifting arm 30. The four-bar linkage formed by the glass connector 10, the front lifting arm 20, the slider 40, the rear lifting arm 30 and the glass connector 10 are connected in sequence. The four movable positions are the hinge point between the glass connector 10 and the front lifting arm 20, the connection point between the front lifting arm 20 and the slider 40, the connection point between the slider 40 and the rear lifting arm 30, and the hinge point between the rear lifting arm 30 and the glass connector 10.
[0073] In this embodiment, as Figure 3 As shown, the front lifting arm slider 22 is provided with a front through groove 23, and one side of the front lifting arm slider 22 is provided with a first front pin 24, further as... Figure 4 As shown, a second front pin 25 is provided on the other side of the front lifting arm slider 22; as Figure 5 and Figure 6 As shown, the slider 40 is provided with a first guide groove 42 and a slider limiting block 41. The slider limiting block 41 is located on the side of the slider 40 facing the forward lifting arm slider 22. The first front pin 24 is located in the guide rail guide groove 51, the second front pin 25 is located in the first guide groove 42, and the slider limiting block 41 is located in the front through groove 23. When the slider 40 moves, the front through groove 23, the first front pin 24, the second front pin 25, the first guide groove 42, and the slider limiting block 41 are used together to limit the position of the forward lifting arm slider 22, so that the forward lifting arm 20 lifts the glass connector 10.
[0074] In this embodiment, as Figure 3 and Figure 14 As shown, the front through groove 23 is an arc-shaped through groove provided along the moving direction of the slider 40, and both ends of the front through groove 23 curve upwards. The moving direction of the slider 40 refers to the forward direction of the vehicle.
[0075] In this embodiment, as Figure 5 and Figure 6 As shown, the first guide groove 42 is set along the moving direction of the slider 40. The first guide groove 42 is located on the lower side of the slider limiting block 41. The slider limiting block 41 is close to the rear end of the first guide groove 42, and the front end of the first guide groove 42 is raised upward.
[0076] In this embodiment, as Figure 7 and Figure 8 As shown, the rear lifting arm slider 32 has a first rear pin 33 and a second rear pin 34 on one side; further as... Figure 5 and Figure 6 As shown, the slider 40 is provided with a second guide groove 43; the first rear pin 33 and the second rear pin 34 are both provided in the second guide groove 43. When the slider 40 moves, the first rear pin 33, the second rear pin 34, and the second guide groove 43 are used together to limit the position of the rear lifting arm slider 32, so that the rear lifting arm 30 lifts the glass connector 10.
[0077] In this embodiment, as Figure 6 As shown, the second guide groove 43 is arranged along the moving direction of the slider 40. The second guide groove 43 includes, from back to front, a first horizontal section 431, a first upward tilting section 432, a second horizontal section 433, a second upward tilting section 434, a top end 435, a first downward tilting section 436, a third horizontal section 437, a second downward tilting section 438, and a fourth horizontal section 439.
[0078] In this embodiment, as Figure 9 and Figure 10 As shown, the guide rail guide groove 51 is arranged along the moving direction of the slider 40. The guide rail guide groove 51 includes an arc segment 511 and a downward sloping segment 512 located at the front end of the arc segment 511. The guide rail guide groove 51 can restrict the movement of the first front pin 24, thereby restricting the position of the glass connector 10 through the first front pin 24.
[0079] In this embodiment, as Figure 6 As shown, the lower end of the slider 40, away from the glass connector 10, has an outwardly flared portion protruding from the surface of the slider 40. The outer surface of the outwardly flared portion is adapted to contact the guide rail 50. The lower end of the slider 40 contacts the guide rail 50 through the outer surface of the outwardly flared portion, which reduces the contact area between the slider 40 and the guide rail 50, thereby reducing the frictional force between them. This allows the drive mechanism to move the slider 40 within the guide rail 50 with only a small power output.
[0080] In this embodiment, as Figure 6 As shown, a damping plate 45 is provided in the middle of the outer expansion section. The damping plate 45 can play a role in damping and reducing the noise when the sunroof movement system is working.
[0081] In this embodiment, as Figure 13 As shown, the drive mechanism includes a drive motor, a flexible shaft 71, a flexible shaft connector 72, and a fixing block 73, further as follows: Figure 6 As shown, a slider limiting groove 44 is provided on the lower side of the middle part of the slider 40. The output end of the drive motor is fixedly connected to one end of the flexible shaft 71, the other end of the flexible shaft 71 is connected to one end of the flexible shaft connector 72, and the other end of the flexible shaft connector 72 is connected to the fixing block 73, which is located in the slider limiting groove 44. When the drive motor is working, it can drive the flexible shaft 71 to move along the moving direction of the slider 40, and the flexible shaft 71 pulls the slider 40 to move through the flexible shaft connector 72 and the fixing block 73.
[0082] Among them, such as Figure 13 As shown, the guide rail 50 is provided with a perforated groove, and the flexible shaft 71 is disposed in the perforated groove and can move back and forth in the perforated groove.
[0083] The sunroof movement system in this embodiment includes the following three stages in its opening process:
[0084] In the first stage, the drive motor rotates, and the flexible shaft 71 pulls the slider 40 to the left. The slider limit block 41, the first guide groove 42 and the second guide groove 43 on the slider 40 all move to the left. In contrast, the second front pin 25 of the front lifting arm 20, which is hinged in the first guide groove 42, and the first rear pin 33 and the second rear pin 34 of the rear lifting arm 30, which are hinged in the second guide groove 43, all move to the right relative to the slider 40. The front through groove 23 of the front lifting arm 20 also moves to the right relative to the slider limit block 41. Specifically, the second front pin 25 slides from the leftmost end of the first guide groove 42 to its rightmost end, and moves to the intersection of the horizontal section 421 and the upward section 422 of the first guide groove 42; the slider limit block 41 moves to the left from the rightmost end of the front through groove 23; the second rear pin 34 moves to the right from the leftmost end of the second guide groove 43, and moves to the top 435 of the second guide groove 43; the first rear pin 33 moves to the right relative to the top 435 of the second guide groove 43, and slides down to the intersection of the second downward section 438 and the fourth horizontal section 439 in the second guide groove 43; the first front pin 24 remains at the right end of the downward section 512 of the guide rail guide groove 51. The state of the sunroof movement system at this time is referenced... Figure 15 As shown, the rear lifting arm 30 is used to lift the rear side of the glass connector 10.

At this time, the slider limit block 41, the first guide groove 42 and the second guide groove 43 on the slider 40 all move to the right. In contrast, the second front pin 25 of the front lifting arm 20, which is hinged in the first guide groove 42, and the first rear pin 33 and the second rear pin 34 of the rear lifting arm 30, which are hinged in the second guide groove 43, all move to the left relative to the slider 40. The front through groove 23 of the front lifting arm 20 also moves to the left relative to the slider limit block 41. Specifically, the second front pin 25 slides from the rightmost end of the first guide groove 42 to its leftmost end, and moves to the intersection of the horizontal section 421 and the upward section 422 of the first guide groove 42; the slider limiting block 41 moves to the right from the leftmost end of the front through groove 23; the first rear pin 33 moves to the left from the rightmost end of the second guide groove 43, and moves to the intersection of the second downward section 438 and the fourth horizontal section 439 in the second guide groove 43; the second rear pin 34 moves to the left within the second guide groove 43, and moves to the top 435 of the second guide groove 43; the first front pin 24 remains within the arc section 511 of the guide rail guide groove 51 and does not move relative to the guide rail guide groove 51. The state of the sunroof movement system at this time is referenced... Figure 15 As shown, the rear lifting arm 30 is used to lift the rear side of the glass connector 10, and the front lifting arm 20 pulls down the front side of the glass connector 10.
[0090] In the second stage, the drive motor continues to pull the slider 40 to the right via the flexible shaft 71, while the second front pin 25 continues to move to the left relative to the slider 40 within the first guide groove 42. After moving into the horizontal section 421 of the first guide groove 42, the second front pin 25 continues to move to the leftmost end. The slider limit block 41 continues to move to the right within the front through groove 23, reaching the rightmost end of the front through groove 23. The first rear pin 33 and the second rear pin 34 continue to slide to the left relative to the slider 40 within the second guide groove 43 until the second rear pin 34 reaches the leftmost end of the second guide groove 43. During this stage, the first front pin 24 remains within the arc section 511 of the guide rail guide groove 51. The state of the sunroof movement system at this time is referenced... Figure 14 As shown, the rear lifting arm 30 pulls down the front side of the glass connector 10.
[0091] The first and second stages involve pulling down the glass connector 10 via the front lifting arm 20 and the rear lifting arm 30. The third stage mainly involves the horizontal movement of the glass connector 10, as detailed below:
