Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to a lifting opening and closing mechanism, a double sunroof assembly and an automobile. Background Art

[0002] With the progress of society and the continuous development of technology, profound changes have taken place in the development of the automobile industry. Among them, the development of intelligent automobiles has entered the second half, and people's demand for intelligent automobiles is becoming stronger and stronger; Automobile intelligence refers to making automobiles have stronger automation and intelligence characteristics by introducing advanced electronic technology, computer technology and communication technology. This transformation is not only in terms of electrification, but also includes multiple aspects such as vehicle autonomous driving, intelligent cockpits, intelligent networking and intelligent electrification. Similarly, consumers have put forward higher requirements for the automation and intelligence of the trunk tailgate.

[0003] Most of the existing automobile trunk tailgates adopt a hatchback shape, that is, the trunk tailgate rotates upward or downward with the roof of the rear vehicle as the axis. This structure allows the trunk to be opened at a very large angle, facilitating the loading of large-sized luggage. However, it also has many disadvantages. Since the trunk tailgate exerts a great pressure on the roof frame during the opening process, the corresponding connection parts of the trunk tailgate and the roof frame are prone to deformation, abnormal noise and even water leakage. At the same time, due to its structural limitations, the height of the rear compartment of the hatchback shape is difficult to be very high. Therefore, when used as a family car, the height of the rear row is limited, and long-term sitting in the rear row will be uncomfortable; Therefore, an automobile structure is needed to overcome the above problems. Summary of the Invention

[0011] As a more preferred embodiment, a warping slider that can slide back and forth along the guide rail is further provided on the guide rail, and the front end of the rear support rod is hinged to the warping slider. Therefore, when the rear sliding foot moves from the rear horizontal section to the warping section along the rear motion chute, the front end of the rear support rod is hinged to the warping slider, so that the rear end of the rear support rod is warped, and thus the rear end of the lifting rod is lifted.

[0012] As a more preferred embodiment, the sliding assembly further includes a sliding connecting rod, the front slider and the rear slider are connected by the sliding connecting rod, and the sliding connecting rod is designed as a long rod that can be deformed to a certain extent to meet the design requirements of a certain radian of the guide rail. When the front slider and the rear slider slide on the guide rail with a certain radian, the sliding assembly can adaptively deform.

[0013] To solve the above problems, the present invention further provides a double sunroof assembly, including:

[0014] front sunroof and rear sunroof;

[0015] A frame structure, wherein the front skylight is arranged at the front portion of the frame structure, and the rear portion of the frame structure is provided with an opening for accommodating the rear skylight;

[0016] The two lifting opening and closing motion mechanisms are symmetrically arranged, and the two guide rails of the two lifting opening and closing motion mechanisms are respectively arranged on both sides of the frame structure; the rear skylight is arranged at the opening at the rear of the frame structure, and the two sides of the rear skylight are respectively fixed to the lifting rods of the two lifting opening and closing motion mechanisms

[0017] A driving device, wherein the driving device is connected to the sliding assembly and can synchronously drive the two front sliding blocks and the rear sliding blocks to move forward and backward along the guide rail; when the driving device drives the front sliding block and the rear sliding block to move forward along the guide rail, the front ends and rear ends of the two lifting rods are synchronously lifted up, and the two lifting rods are in a lifted state at the same time, at this time the rear skylight is lifted up and protrudes above the frame structure, and continues to drive the sliding assembly to move forward, the rear skylight moves to above the front skylight, and the rear skylight opens; then the driving device is used to reversely drive the front sliding block and the rear sliding block to move backward along the guide rail, and when the two rear support rods are limited by the corresponding limiting members, the front ends and rear ends of the lifting rods are synchronously recovered, the two lifting rods are in a recovered state, the rear skylight is stored in the opening of the frame structure, and the rear skylight is closed and flush with the front skylight.

[0018] As a more preferred embodiment, covering grooves for accommodating the guide rails are provided on both sides of the frame structure, and the two guide rails are arranged in the covering grooves. The covering grooves can ensure the effective connection between the guide rails and the frame structure, increase the installation strength, improve the skylight mode, and reduce the noise risk.

[0019] As a more preferred embodiment, a drainage groove is provided in the joint between the frame structure and the front skylight and the rear skylight, a waterproof sealing strip with an openable and closable design is provided at the top of the drainage groove, a drainage piece for covering the rear end of the drainage groove is provided at the rear end of the drainage groove, and a drainage hole and a windproof and dustproof curtain covering the drainage hole are provided on the drainage piece; firstly, the drainage piece can take into account drainage while preventing rear wind noise from entering the skylight and the cockpit, thereby reducing noise while having better integration and saving costs.

[0020] As a more preferred embodiment, a luggage support for fixing a luggage rack is further provided on the frame structure. By directly fixing the luggage support to the frame structure, firstly, the functions are more integrated and the cost is saved; secondly, a universal mounting bracket can be adopted, thus saving the mold cost; finally, the high-strength mounting points can also improve the mounting strength of the luggage rack.

[0021] As a more preferred embodiment, the frame structure includes a front cross beam, a middle cross beam and two side beams, and the frame structure is formed by enclosing and splicing the front cross beam, the middle cross beam and the two side beams. With such a design, on the one hand, it can replace the commonly used integral stamping frame and reduce the stamping process requirements; on the other hand, since only small pieces of plates are stamped, the material utilization rate will also increase.

[0022] As a more preferred embodiment, a taillight is further provided at the rear end of the rear skylight. When the rear skylight is opened or closed, the taillight moves with the rear skylight. In this way, the style of the taillight is more novel and more beautiful.

[0023] As a more preferred embodiment, the taillight is powered by a power cord, and the power cord is a crawler-type flat wire, which reduces the wear of the power cord during the opening and closing processes of the rear skylight and extends the service life of the power cord.

[0024] To solve the above problems, the present invention further provides an automobile, including:

[0025] A trunk;

[0026] The above-mentioned double skylight assembly, wherein the rear skylight is arranged above the trunk, and the opening and closing of the trunk are realized by the opening and closing of the rear skylight.

[0027] As described above, the lifting opening and closing movement mechanism, the double skylight assembly and the automobile of the present invention have the following beneficial effects: When the lifting opening and closing movement mechanism of the present invention works, firstly, it drives the front slider and the rear slider to move forward along the guide rail, and the front support rod and the rear support rod move relatively backward along the front movement chute and the rear movement chute. When the front support rod moves to the rear end of the front movement chute, it is limited, and at this time, the front end of the lifting rod is lifted. At the same time, the rear support rod drives the rear end of the lifting rod to be lifted synchronously, and the lifting rod is in a jacking state. At this time, continue to drive the sliding assembly to move forward, and the lifting rod remains in the jacking state; then drive the front slider and the rear slider to move backward along the guide rail in the reverse direction. The rear support rod moves relatively forward along the rear movement chute under the action of the limiting member, and at the same time, it is transmitted to the front support rod through the lifting rod, so that it also moves relatively forward along the front movement chute. The lifting rod is synchronously driven by the front support rod and the rear support rod to be retracted, and at this time, the lifting rod is in a retracted state;

[0028] When the double sunroof assembly of the present invention is in use, the driving device can be used to drive the front slider and the rear slider to move forward along the guide rail, so that the front ends and the rear ends of the two lifting rods are simultaneously jacked up, and the two lifting rods are in the jacking state at the same time. At this time, the rear sunroof is jacked up and protrudes above the frame structure. Continuing to drive the sliding assembly forward, the rear sunroof moves above the front sunroof, and the rear sunroof opens; then the driving device is used to drive the front slider and the rear slider to move backward along the guide rail in the reverse direction. When the two rear support rods are limited by the corresponding limit members, the front ends and the rear ends of the lifting rods are synchronously retracted, and the two lifting rods are in the retracted state. The rear sunroof is received in the opening of the frame structure, and the rear sunroof is closed and flush with the front sunroof; in this way, the opening and closing of the double sunroof assembly can be realized conveniently and quickly;

[0029] The automobile of the present invention uses the above double sunroof assembly, and the rear sunroof is arranged above the trunk. In this way, when in use, the opening and closing of the trunk are realized by the opening and closing of the rear sunroof. Compared with the hatchback shape of the traditional automobile trunk tailgate, the pressure of the rear sunroof is shared by the frame structure of the entire sunroof assembly, reducing the pressure at the connection. Therefore, during use, the overall deformation of the frame structure and the rear sunroof structure is small, and it is not easy to generate abnormal noises and leaks; at the same time, since the front sunroof and the rear sunroof of the automobile of the present invention can be kept flush, it is possible to ensure that the height of the rear row can be the same as that of the front row, and passengers can obtain the same riding experience as in the front row when sitting in the rear row.

[0030] In summary, the lifting and opening / closing motion mechanism, the double sunroof assembly and the automobile of the present invention reduce the deformation of the frame structure and the sunroof body during the opening and closing of the rear sunroof through the design of the double sunroof structure with lifting and opening / closing, and at the same time ensure the head space of the rear row passengers, solving the problems of easy deformation and limited rear space caused by the hatchback shape of the automobile trunk tailgate in the prior art.

[0092] AsFigures 1 to 6 As shown in the figure, the present invention provides a lifting and opening / closing motion mechanism 1, including:

[0093] A guide rail 11, on which a limiting member 111 is provided;

[0094] A sliding assembly. The lifting and sliding member includes a front slider 12 and a rear slider 13. A front motion chute 121 is provided on the front slider 12, and a rear motion chute 131 is provided on the rear slider 13. The front slider 12 and the rear slider 13 are connected to each other and can slide back and forth along the guide rail 11;

[0095] A lifting assembly 15, which includes a lifting rod 151, a front support rod 152 slidably disposed in the front motion chute 121, and a rear support rod 153 slidably disposed in the rear motion chute 131. The front end of the front support rod 152 and the rear end of the rear support rod 153 are respectively hinged to the front end and the rear end of the lifting rod 151. When the front support rod 152 and the rear support rod 153 move forward or backward along the front motion chute 121 and the rear motion chute 131, the lifting rod 151 is synchronously driven by the front support rod 152 and the rear support rod 153 to be lifted or retracted;

[0096] Drive the front slider 12 and the rear slider 13 to move forward along the guide rail 11. The front support rod 152 and the rear support rod 153 move backward relative to each other along the front motion chute 121 and the rear motion chute 131. When the front support rod 152 moves to the rear end of the front motion chute 121, it is limited. At this time, the front end of the lifting rod 151 is lifted, and at the same time, the rear support rod 153 drives the rear end of the lifting rod 151 to be lifted synchronously. The lifting rod 151 is in a lifted state. At this time, continue to drive the sliding assembly to move forward, and the lifting rod 151 remains in the lifted state; then drive the front slider 12 and the rear slider 13 to move backward along the guide rail 11 in the reverse direction. The rear support rod 153 moves forward relative to the front along the rear motion chute 131 under the action of the limiting member 111. At the same time, it is transmitted to the front support rod 152 through the lifting rod 151, so that it also moves forward relative to the front along the front motion chute 121. The lifting rod 151 is synchronously driven by the front support rod 152 and the rear support rod 153 to be retracted. At this time, the lifting rod 151 is in a retracted state.

[0097] To better introduce the present invention, the following specific applications are now combined for further illustration: When the lifting and opening / closing motion mechanism 1 of the present invention is working, it first drives the front slider 12 and the rear slider 13 to move forward along the guide rail 11. The front support rod 152 and the rear support rod 153 move relatively backward along the front motion chute 121 and the rear motion chute 131. When the front support rod 152 moves to the rear end of the front motion chute 121, it is limited. At this time, the front end of the lifting rod 151 is lifted. At the same time, the rear support rod 153 drives the rear end of the lifting rod 151 to be lifted synchronously. The lifting rod 151 is in the lifting state, as Figure 1 shown. At this time, continue to drive the sliding assembly forward, and the lifting rod 151 remains in the lifting state; then drive the front slider 12 and the rear slider 13 to move backward along the guide rail 11 in the reverse direction. The rear support rod 153 moves relatively forward along the rear motion chute 131 under the action of the limiting member 111. At the same time, it is transmitted to the front support rod 152 through the lifting rod 151, so that it also moves relatively forward along the front motion chute 121. The lifting rod 151 is synchronously driven to retract through the front support rod 152 and the rear support rod 153 respectively. At this time, the lifting rod 151 is in the retracted state, as Figure 6 shown.

[0098] In this embodiment, as Figure 2 shown, the front motion chute 121 includes a first front horizontal section 121a, a convex section 121b, and a second front horizontal section 121c that are sequentially connected from front to back, as Figure 3As shown, the rear movement groove includes a rear horizontal section 131a and a warping section 131b that are sequentially connected from front to back; a first front sliding foot 152a and a second front sliding foot 152b are provided on the front support rod 152, and the first front sliding foot 152a and the second front sliding foot 152b are slidably arranged in the front movement chute 121. A rear sliding foot 153a is provided on the rear support rod 153, and the rear sliding foot 153a is slidably arranged in the rear movement chute 131; driving the front slider 12 and the rear slider 13 to move forward along the guide rail 11, the front support rod 152 and the rear support rod 153 move relatively backward along the front movement chute 121 and the rear movement chute 131. The first front sliding foot 152a moves along the front movement chute 121 from the first front horizontal section 121a to the convex section 121b, and the second front sliding foot 152b moves along the front movement chute 121 from the convex section 121b to the second front horizontal section 121c. The second front sliding foot 152b is limited when it moves to the rear end of the front movement chute 121. At this time, the first front sliding foot 152a is located at the top of the convex section 121b, and the front end of the lifting rod 151 is lifted. At the same time, the rear sliding foot 153a moves along the rear movement chute 131 from the rear horizontal section 131a to the warping section 131b, driving the rear end of the lifting rod 151 to be lifted. The lifting rod 151 is in a jacking state. At this time, continue to drive the sliding assembly to move forward, and the lifting rod 151 remains in the jacking state; continue to drive the front slider 12 and the rear slider 13 to move backward along the guide rail 11. The rear support rod 153 moves forward along the rear movement chute 131 under the action of the limiting member 111, and at the same time is transmitted to the front support rod 152 through the lifting rod 151, so that it moves forward along the front movement chute 121. The rear sliding foot 153a moves along the rear movement chute 131 from the warping section 131b to the rear horizontal section 131a, driving the rear end of the lifting rod 151 to retract. The second front sliding foot 152b moves along the front movement chute 121 from the second front horizontal section 121c to the convex section 121b. The first sliding foot moves from the convex section 121b to the first horizontal section, and when the second front sliding foot 152b moves to the top of the convex section 121b, the front end of the lifting rod 151 also retracts synchronously. At this time, the lifting rod 151 is in a retracted state.

[0099] In this embodiment, as Figure 1 and Figure 6As shown, a warping slider 112 that can slide back and forth along the guide rail 11 is further provided on the guide rail 11. The front end of the rear support rod 153 is hinged to the warping slider 112. Therefore, when the rear sliding foot 153a moves from the rear horizontal section 131a towards the warping section 131b along the rear movement chute 131, the front end of the rear support rod 153 is hinged to the warping slider 112, thereby causing the rear end of the rear support rod 153 to tilt upwards, and further causing the rear end of the lifting rod 151 to be lifted. Further, in this embodiment, when the front slider 12 and the rear slider 13 are driven to move backwards along the guide rail 11 in the reverse direction, the limiting member 111 limits the rear support rod 153 through the warping slider 112, so that the rear support rod 153 moves relatively forward along the rear movement chute 131 under the action of the limiting member 111.

[0100] In this embodiment, as Figure 1 and Figure 6 shown, the sliding assembly further includes a sliding link 14. The front slider 12 and the rear slider 13 are connected by the sliding link 14. The sliding link 14 is designed as a long rod that can be deformed to a certain extent to meet the design requirements of a certain radian of the guide rail 11. When the front slider 12 and the rear slider 13 slide along the guide rail 11 with a certain radian, the sliding assembly can adaptively deform.

[0101] To solve the above problems, as Figures 7 to 10 shown, the present invention further provides a double sunroof assembly, including:

[0102] A front sunroof 8 and a rear sunroof 9;

[0103] A frame structure 2. The front sunroof 8 is arranged at the front part of the frame structure 2, and an opening for accommodating the rear sunroof 9 is arranged at the rear part of the frame structure 2;

[0104] Two of the above-mentioned lifting and opening / closing movement mechanisms 1 are symmetrically arranged. The two guide rails 11 of the two lifting and opening / closing movement mechanisms 1 are respectively arranged on both sides of the frame structure 2; the rear sunroof 9 is arranged at the opening at the rear part of the frame structure 2, and both sides of the rear sunroof 9 are respectively fixed to the lifting rods 151 of the two lifting and opening / closing movement mechanisms 1

The rear skylight 9 is received in the opening of the frame structure 2, and the rear skylight 9 is closed and flush with the front skylight 8.

[0106] To better introduce the present invention, the following specific applications are now combined for further illustration: When the double skylight assembly of the present invention is in use, the driving device can be used to drive the front slider 12 and the rear slider 13 to move forward along the guide rail 11, so that the front ends and the rear ends of the two lifting rods 151 are synchronously jacked up, and the two lifting rods 151 are simultaneously in the jacking state. At this time, the rear skylight 9 is jacked up and protrudes above the frame structure 2. Continuing to drive the sliding assembly forward, the rear skylight 9 moves above the front skylight 8, and the rear skylight 9 is opened; then, the driving device is used to drive the front slider 12 and the rear slider 13 to move backward along the guide rail 11 in the reverse direction. When the two rear support rods 153 are limited by the corresponding limit members 111, the front ends and the rear ends of the lifting rods 151 are synchronously retracted, and the two lifting rods 151 are in the retracted state. The rear skylight 9 is received in the opening of the frame structure 2, and the rear skylight 9 is closed and flush with the front skylight 8; in this way, the opening and closing of the double skylight assembly can be achieved conveniently and quickly.

[0107] In this embodiment, as Figure 11As shown, both sides of the frame structure 2 are provided with covering grooves 231 for accommodating the guide rails 11, and the two guide rails 11 are arranged in the covering grooves 231. The covering grooves 231 can ensure the effective connection between the guide rails 11 and the frame structure 2. The double sunroof assembly of the present invention has high requirements for the load-bearing guide rails 11 due to its size and the load-bearing double sunroof structure. This structural design can increase the installation strength, improve the sunroof modality and reduce the noise risk, and avoid the problem of insufficient overall structural strength caused by the traditional solution of fixing the guide rail 11 to the vehicle body or the sunroof frame on one side; further, in the present embodiment, bolts are passed through the guide rails 11 and the frame structure 2, and then the guide rails 11 are locked and fixed to the frame structure 2 by nuts. At the same time, structural adhesive is used to effectively connect the lower part of the guide rail 11 to the frame structure 2 to increase the installation strength.

[0108] In this embodiment, if Figure 7 , Figure 8 , Figure 9 as well as Figure 10 As shown, a drainage groove is provided in the joint between the frame structure 2 and the front skylight 8 and the rear skylight 9, and a waterproof sealing strip 4 with an openable and closable design is provided at the top of the drainage groove, and a drainage member 7 for covering the rear end of the drainage groove is provided at the rear end of the drainage groove, and a drainage hole 71 and a windproof and dustproof curtain 72 covering the drainage hole 71 are provided on the drainage member 7; firstly, the drainage member 7 can take into account drainage while preventing the rear wind noise from entering the skylight and the cockpit, thereby reducing noise while having better integration and saving costs.

[0109] In this embodiment, if Figure 11As shown, the frame structure 2 includes a front cross beam 21, a middle cross beam 22 and two side beams 23. The frame structure 2 is formed by enclosing and splicing the front cross beam 21, the middle cross beam 22 and the two side beams 23. With such a design, on the one hand, it can replace the commonly used integral stamping frame, reducing the stamping process requirements. On the other hand, since only small pieces of plates are stamped, the material utilization rate will also increase. Further, in this embodiment, the front cross beam 21 is perpendicular to the side beam 23, and both ends of the front cross beam 21 overlap with one end of the two side beams 23. At the overlapping area, a number of special-shaped reinforcing ribs 24 are provided at the corresponding positions of the front cross beam 21 and the side beam 23. The gap between the front cross beam 21 and the side beam 23 is filled with waterproof glue, and at the same time, the front cross beam 21 and the side beam 23 are fixed to each other through a number of evenly arranged welding points 25. Similarly, the middle cross beam 22 is perpendicular to the side beam 23, and both ends of the middle cross beam 22 overlap with the middle parts of the two side beams 23. At the overlapping area, a number of special-shaped reinforcing ribs 24 are provided at the corresponding positions of the middle cross beam 22 and the side beam 23. The gap between the middle cross beam 22 and the side beam 23 is filled with waterproof glue, and at the same time, the middle cross beam 22 and the side beam 23 are fixed to each other through a number of evenly arranged welding points 25. Through the above strengthening structure and waterproof structure, the mechanical strength and waterproof performance of the frame structure 2 are further improved.

[0110] Further, in this embodiment, the covering groove 231 is provided on the side beam 23.

[0111] In this embodiment, as Figure 7 、 Figure 8 、 Figure 9 and Figure 10 shown, cover plate structures 3 are respectively laid above the front cross beam 21, the middle cross beam 22 and the two side beams 23. The cover plate structure 3 is used to prevent rainwater and dust from entering and protect the internal structure of the double skylight assembly. The cover plate structure 3 includes a front cover plate 31 laid on the front cross beam 21, a front side cover plate 32 laid on the front part of the side beam 23 and a rear side cover plate 33 laid on the rear part of the side beam 23. Further, in this embodiment, in order to ensure the waterproof performance at the joint of the front side cover plate 32 and the rear side cover plate 33, waterproof foam 34 and waterproof rubber strips 35 are filled.

[0112] In this embodiment, as Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, a luggage support 6 for fixing a luggage rack is further provided on the frame structure 2. By directly fixing the luggage support 6 on the frame structure 2, firstly, the function is more integrated and the cost is more saved; secondly, a generalized mounting bracket can be adopted, thus saving the mold cost; finally, the high-strength mounting points can also improve the mounting strength of the luggage rack. Further, in this embodiment, five luggage supports 6 are respectively arranged on both sides of the frame structure 2 to meet the requirements of the roof luggage weight and solve the problem that such an installation structure cannot be provided on the body of a traditional top-mounted skylight vehicle.

[0113] In this embodiment, as Figure 7 、 Figure 8 、 Figure 9 and Figure 10 shown, a tail lamp 5 is further provided at the rear end of the rear skylight 9. When the rear skylight 9 is opened or closed, the tail lamp 5 moves with the rear skylight 9. In this way, the style of the tail lamp 5 is more novel and more beautiful.

[0114] In this embodiment, as Figure 9 shown, the tail lamp 5 is powered by a power cord, and the power cord adopts a crawler-type flat wire 51 to reduce the wear of the power cord during the opening and closing processes of the rear skylight 9 and extend the service life of the power cord. Further, in this embodiment, 40 mm is reserved at the end of the power cord harness for adding a fixing structure to ensure that the harness does not deviate when retracting and reduce the fatigue at the joint.

[0115] To solve the above problems, the present invention further provides an automobile, including:

[0116] A trunk;

[0117] The above double skylight assembly, wherein the rear skylight 9 is arranged above the trunk, and the opening and closing of the trunk are realized by the opening and closing of the rear skylight 9.

[0118] The automobile of the present invention uses the above double skylight assembly and arranges the rear skylight 9 above the trunk. In this way, during use, the opening and closing of the trunk are realized by the opening and closing of the rear skylight 9. Compared with the hatchback styling of the trunk lid of a traditional automobile, the pressure of the rear skylight 9 is shared by the frame structure 2 of the entire skylight assembly, reducing the pressure at the connection. Therefore, during use, the overall deformation of the frame structure 2 and the rear skylight 9 is small, and abnormal noises and water leakage are not likely to occur. At the same time, since the front skylight 8 and the rear skylight 9 of the automobile of the present invention can be kept flush, the height of the rear row can be guaranteed to be the same as that of the front row, and passengers can obtain the same riding experience as in the front row when sitting in the rear row.

[0119] In summary, the lifting and opening / closing motion mechanism, double sunroof assembly and vehicle of the present invention with the double sunroof structure designed for lifting and opening / closing reduce the deformation of the frame structure 2 and the sunroof body during the opening / closing process of the rear sunroof 9, while ensuring the headroom of the rear passengers, and solve the problems of easy deformation caused by the hatchback styling of the vehicle trunk tailgate and limited rear space in the prior art. Therefore, the present invention effectively overcomes various drawbacks in the prior art and has high industrial utilization value.

[0120] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
