[0032] The safety seat of a vehicle is a seat designed for infants and children of different ages, installed in a vehicle, and capable of effectively improving the safety of infants and children during vehicle rides. With the gradual improvement of vehicle safety awareness, safety seats have been widely used. Traditional safety seats are all fixed to the vehicle seat by installation. In actual use, due to the growth of infants and children or different usage requirements for the tilt angle of the seat, it is often necessary to adjust the tilt angle of the safety seat.

[0033] The safety seats in related technologies usually include a seat body and a base. Among them, there is often no component for adjusting the relative angle between the seat body and the base, resulting in the angle between the seat body and the base in the safety seat often being in a fixed form, and thus it is difficult to adapt to different growth stages of infants and children.

[0034] Please refer to in combination Figures 1 to 8, an embodiment of the present utility model provides a safety seat 100, which includes a seat body 10 and a base 20. Among them, the seat body 10 includes a seat cushion part 11 and a backrest part 12 arranged on the seat cushion part 11; the base 20 includes an arc-shaped bracket 21 and an angle adjustment component 22, and the angle adjustment component 22 drives the seat cushion part 11 to slide relative to the arc-shaped bracket 21 to adjust the angle of the seat cushion part 11; the angle adjustment component 22 is arranged on the arc-shaped bracket 21.

[0035] The safety seat 100 is a seat installed in a vehicle and used for infants and young children to ride, providing a safer riding environment for infants and young children. Generally, the safety seat 100 is detachably connected to the vehicle seat.

[0036] The safety seat 100 includes a seat body 10 and a base 20. Among them, the seat body 10 is the main load-bearing member and is the part directly in contact with the infant and young child passengers in the safety seat 100, so as to support the infants and young children; the function of the base 20 is to provide a supporting effect for the seat body 10, that is, the base 20 is used to connect the seat body 10 to the vehicle seat or the vehicle floor.

[0037] Furthermore, the seat body 10 includes a seat cushion part 11 and a backrest part 12, which means that in these embodiments of the present utility model, the seat body 10 is mainly used to provide support and protection for the infant and young child passengers who can sit upright. Among them, the seat cushion part 11 is used to support the buttocks and legs of the infant and young child passengers, and the backrest part 12 is used to support the back and head of the infant and young child passengers. The seat cushion part 11 and the backrest part 12 cooperate together to provide a comfortable and safe riding experience for the infant and young child passengers.

[0038] The backrest part 12 is arranged on the seat cushion part 11. A possible implementation manner is that the skeleton of the seat cushion part 11 and the skeleton of the backrest part 12 are detachably connected through connecting pieces such as screws, bolts, and stud bolts, or the skeleton of the seat cushion part 11 and the skeleton of the backrest part 12 can also be fixed together by welding to improve the structural consistency between the seat cushion part 11 and the backrest part 12.

[0039] It can be understood that generally, an included angle is formed between the seat cushion part 11 and the backrest part 12, that is, an included angle is formed between the plane where the seat cushion part 11 is located and the plane where the backrest part 12 is located. In some embodiments, the included angle between the seat cushion part 11 and the backrest part 12 can be set to be fixed, and in some embodiments, the included angle between the seat cushion part 11 and the backrest part 12 can also be set to be adjustable.

[0040] The base 20 includes an arc-shaped bracket 21 and an angle adjustment component 22. Among them, the function of the arc-shaped bracket 21 is to allow the chair body 10 to slide. And because the arc-shaped bracket 21 has a certain curvature, when the chair body 10 slides along the arc-shaped bracket 21, the angles between the seat cushion part 11 and the horizontal plane, and between the backrest part 12 and the horizontal plane can be adjusted, so as to meet the needs of infant passengers for different riding postures.

[0041] The function of the angle adjustment component 22 is to drive the seat cushion part 11 to slide relative to the arc-shaped bracket 21 to adjust the angle of the seat cushion part 11. That is to say, the angle adjustment component 22 acts on the seat cushion part 11 of the chair body 10, and by driving the seat cushion part 11 to slide relative to the arc-shaped bracket 21, the chair body 10 is driven to slide relative to the arc-shaped bracket 21, and finally the angle adjustment between the chair body 10 and the base 20 is realized.

[0042] In this way, since when the safety seat 100 is installed in the vehicle, the included angle between the plane where the seat cushion part 11 is located and the horizontal plane is small, when the angle adjustment component 22 drives the seat cushion part 11 to slide along the arc-shaped bracket 21, the angle adjustment component 22 can output more thrust or pulling force in the horizontal direction, and the gravity of the chair body 10 has less influence on the angle adjustment component 22. Therefore, compared with the way of using the angle adjustment component 22 to drive the backrest part 12, the operating load of the angle adjustment component 22 is reduced, the operating difficulty of the angle adjustment component 22 is reduced, and the angle adjustment efficiency of the chair body 10 is improved.

[0043] The angle adjustment component 22 is arranged on the arc-shaped bracket 21, which means that at least some components in the angle adjustment component 22 are connected to the arc-shaped bracket 21 to form a stable structure, so that the angle adjustment component 22 can drive the seat cushion part 11 to slide relative to the arc-shaped bracket 21 more stably.

[0044] Exemplarily, in some embodiments, the angle adjustment component 22 can be arranged at one end of the arc-shaped bracket 21 close to the seat cushion part 11, so as to reduce the size of each component in the angle adjustment component 22, which is beneficial to the miniaturization of the product.

[0045] In these embodiments of the present invention, the angle adjustment component 22 can be arranged as a structure in which a cylinder drives a push rod to operate, so as to drive the chair body 10 to slide along the arc-shaped bracket 21 by using the connection between the push rod and the chair body 10; or, in some embodiments, the angle adjustment component 22 can also be arranged as a structure in which a motor drives a gearbox to operate, and then drives the chair body 10 to slide along the arc-shaped bracket 21. The above can be selected according to the actual situation of the product.

[0046] The technical solution of the present utility model realizes the angle adjustment of the chair body 10 by setting the angle adjustment component 22 to drive the seat cushion part 11 to slide relative to the arc-shaped bracket 21. When the angle adjustment component 22 works, the load applied by the chair body 10 in the gravity direction on the angle adjustment component 22 can be reduced, thereby reducing the operation difficulty of the angle adjustment component 22 and improving the angle adjustment efficiency.

[0047] In some embodiments, the angle adjustment component 22 includes a driving member 221, a first sliding member 222, and a transmission component 223. The driving member 221 drives the first sliding member 222 to slide along the arc-shaped bracket 21, and the first sliding member 222 is fixedly connected to the seat cushion part 11.

[0048] The driving member 221 is the power source of the angle adjustment component 22. Among them, the driving member 221 can be equipped with a rechargeable power source by itself, or the driving member 221 can also obtain electricity by connecting to an external power source.

[0049] In these embodiments of the present utility model, the driving member 221 can be set as a motor.

[0050] The first sliding member 222 is a component used for sliding connection with the arc-shaped bracket 21 in the angle adjustment component 22. Among them, by connecting the first sliding member 222 to the seat cushion part 11, the first sliding member 222 can be used to drive the seat cushion part 11 to slide relative to the arc-shaped bracket 21.

[0051] The function of the transmission component 223 is to transmit the mechanical energy generated by the driving member 221 to the first sliding member 222 to drive the first sliding member 222 to slide along the arc-shaped bracket 21.

[0052] At the same time, since the first sliding member 222 is fixedly connected to the seat cushion part 11, the first sliding member 222 drives the chair body 10 to realize angle adjustment through the seat cushion part 11. That is to say, in these embodiments of the present utility model, the output end of the transmission component 223 is connected to the first sliding member 222, and the first sliding member 222 is fixedly connected to the seat cushion part 11. Furthermore, the transmission component 223 drives the first sliding member 222 to slide along the arc-shaped bracket 21 under the action of the driving member 221, and further drives the entire chair body 10 to slide along the arc-shaped bracket 21 by driving the seat cushion part 11 to slide. Since the arc-shaped bracket 21 has a certain curvature, when the chair body 10 slides along the arc-shaped bracket 21, the included angle between the seat cushion part 11 and the horizontal plane, as well as the included angle between the backrest 12 and the horizontal plane, will both change, thus realizing the angle adjustment of the chair body 10.

[0053] In some embodiments, the driving member 221 is disposed at an end of the arc-shaped bracket 21 relatively far from the backrest portion 12; the arc-shaped bracket 21 includes a first guiding structure 211, and the first guiding structure 211 is disposed at an end of the arc-shaped bracket 21 close to the seat portion 11, and the first sliding member 222 is slidably disposed along the first guiding structure 211; the arc-shaped bracket 21 further includes two spaced-apart support plates 212; the number of the first guiding structures 211 is two, and the two first guiding structures 211 are respectively disposed on the two support plates 212; the projections of the two first guiding structures 211 along the spacing direction of the two support plates 212 coincide.

[0054] The driving member 221 is disposed at an end of the arc-shaped bracket 21 relatively far from the backrest portion 12, that is, the driving member 221 is disposed at an end of the arc-shaped bracket 21 relatively close to the seat portion 11, so as to shorten the distance between the driving member 221 and the seat portion 11, which is beneficial to driving the seat portion 11 to slide along the arc-shaped bracket 21 by the driving member 221.

[0055] The arc-shaped bracket 21 includes a first guiding structure 211, and the first guiding structure 211 is disposed at an end of the arc-shaped bracket 21 close to the seat portion 11, and the first sliding member 222 is slidably disposed along the first guiding structure 211.

[0056] The first guiding structure 211 is used to provide a guiding effect for the sliding of the first sliding member 222 relative to the arc-shaped bracket 21. Therefore, the setting parameters of the first guiding structure 211 can be the same as those of the arc-shaped bracket 21. Exemplarily, in the setting section of the first guiding structure 211, when the arc-shaped bracket 21 is arc-shaped, the section of the first guiding structure 211 can be set to be an arc matching the arc-shaped bracket 21; when the arc-shaped bracket 21 is linear, the section of the first guiding structure 211 can also be set to be a straight line matching the arc-shaped bracket 21.

[0057] In these embodiments of the present invention, the first guiding structure 211 can be, but is not limited to, a rail or a guide groove structure. During installation, a part of the first sliding member 222 can be disposed in the foregoing rail or guide groove structure. When the driving member 221 works, the first sliding member 222 can slide along the foregoing rail or guide groove structure under the action of the transmission assembly 223, and drive the seat portion 11 to slide accordingly, and finally realize the angle adjustment between the chair body 10 and the base 20.

[0058] The first guiding structure 211 is disposed at an end of the arc-shaped bracket 21 close to the seat portion 11, so as to facilitate the setting of the first sliding member 222.

[0059] The arc-shaped bracket 21 further includes two spaced-apart support plates 212; the number of the first guiding structures 211 is two, and the two first guiding structures 211 are respectively disposed on the two support plates 212.

[0060] The support plate 212 is a component in the arc-shaped bracket 21 for supporting the aforementioned angle adjustment component 22, and is the main structure of the arc-shaped bracket 21. The two support plates 212 are arranged at intervals to form the overall contour of the arc-shaped bracket 21. At the same time, other components of the placement base 20 can be arranged between the two support plates 212 arranged at intervals, so as to provide an installation space for other components of the base 20 while reducing the self-weight and having higher reliability.

[0061] Correspondingly, in these embodiments of the present invention, the number of the first guiding structures 211 can be set to two, and the two first guiding structures 211 are respectively arranged on the two support plates 212. In this way, the two first guiding structures 211 can respectively provide limits at both ends of the first sliding member 222, improving the connection stability between the first sliding member 222 and the first guiding structure 211, and improving the guiding accuracy of the first guiding structure 211.

[0062] In some embodiments, the projections of the two first guiding structures 211 along the interval direction of the two support plates 212 coincide.

[0063] In these embodiments of the present invention, the projections of the two first guiding structures 211 along the interval direction of the two second support plates 212 coincide. In this way, the first sliding member 222 can be set as a rod-shaped structure arranged along the interval direction of the two support plates 212, which is beneficial to improving the uniformity of the forces at the positions where the chair body 10 is connected to the first sliding member 222, and further improving the stability of the chair body 10 sliding along the arc-shaped bracket 21.

[0064] In some embodiments, the planes where the two support plates 212 are located can be set to be parallel to each other, that is, the two support plates 212 are arranged in parallel at intervals. At this time, the first sliding member 222 can be set as a rod-shaped structure perpendicular to the two support plates 212 to further improve the uniformity of the forces at the connection positions between the chair body 10 and the first sliding member 222, and further improve the stability of the chair body 10 sliding along the arc-shaped bracket 21.

[0065] In some embodiments, the first guiding structure 211 is a long slot, and the first sliding member 222 is a guiding rod.

[0066] The first guiding structure 211 is a long slot. A possible implementation manner is that the first guiding structure 211 is a hole structure penetrating along the thickness direction of the support plate 212, and the shape of the first guiding structure 211 extending on the support plate 212 is strip-shaped. Such a setting can simplify the forming process of the first guiding structure 211, reduce the processing time of the safety seat 100, and improve the processing efficiency.

[0067] In these embodiments of the present utility model, the number of the support plates 212 is two, and the two support plates 212 are arranged at intervals. A first guiding structure 211 is provided on each support plate 212, and the two first guiding structures 211 are also arranged at intervals along the direction of the interval between the two support plates 212. At this time, the first sliding member 222 is set as a guiding rod, and both ends of the guiding rod pass through the first guiding structures 211 on the two support plates 212 respectively and then are connected to the seat cushion portion 11, so as to be connected to the seat cushion portion 11 while sliding along the first guiding structure 211. This reduces the complexity of the production process of the safety seat 100 and is beneficial to improving the production and installation efficiency.

[0068] In some embodiments, the transmission assembly 223 includes a transmission rod 2231 and a transmission block 2232 that cooperates with the transmission rod 2231. The driving member 221 drives the transmission block 2232 to move through the transmission rod 2231; the moving direction of the first sliding member 222 is not the same as the moving direction of the transmission block 2232, and the first sliding member 222 is slidably arranged relative to the transmission block 2232.

[0069] In these embodiments of the present utility model, the transmission rod 2231 is connected to the driving member 221 and is directly driven by the driving member 221. The transmission block 2232 moves under the driving action of the transmission rod 2231, and then drives the first sliding member 222 to slide relative to the arc-shaped bracket 21.

[0070] Exemplarily, in the embodiment where the driving member 221 is a cylinder, the driving member 221 can drive the transmission rod 2231 to reciprocate axially. At this time, the transmission block 2232 can be arranged on the transmission rod 2231 to follow the transmission rod 2231 to reciprocate axially along the axis of the transmission rod 2231; in the embodiment where the driving member 221 is a motor, the transmission rod 2231 can be set as a lead screw, and the transmission block 2232 is set to be in threaded cooperation with the transmission rod 2231, so that the transmission block 2232 reciprocates axially along the axis of the transmission rod 2231.

[0071] It should be noted that the moving direction of the first sliding member 222 is not the same as the moving direction of the transmission block 2232, and the first sliding member 222 is slidably arranged relative to the transmission block 2232 because their movement trajectories are completely different. That is, the first sliding member 222 slides relative to the arc-shaped bracket 21, and its movement trajectory is an arc matching the arc-shaped bracket 21, while the transmission block 2232 reciprocates axially along the transmission rod 2231, and its movement trajectory is linear.

[0072] That is to say, when the driving member 221 is working, the general directions of movement of the first sliding member 222 and the transmission block 2232 can be the same (both moving from one end of the arc-shaped bracket 21 to the other end), but the movements they make are actually different. That is, the first sliding member 222 slides along an arc-shaped trajectory, and the transmission block 2232 moves along the axial direction of the transmission rod 2231.

[0073] Based on this, since the first sliding member 222 slides under the driving action of the transmission block 2232, there is a certain connection relationship between the two. At this time, it is necessary to set the first sliding member 222 and the transmission block 2232 to be relatively slidably arranged, that is, the relative position relationship between the two can be changed. In this way, while the transmission block 2232 moves in a straight line, the first sliding member 222 can follow the transmission block 2232 and move in a direction intersecting the moving direction, thereby realizing the sliding of the first sliding member 222 along the arc-shaped trajectory.

[0074] In these embodiments of the present invention, it can be set that the transmission rod 2231 includes a lead screw (not labeled) rotating in the arc-shaped bracket 21, the transmission block 2232 includes a lead screw nut (not labeled) cooperating with the lead screw, and the transmission block 2232 further has a chute 101 slidably cooperating with the first sliding member 222.

[0075] In these embodiments of the present invention, it can be set that the lead screw nut is threadedly connected to the lead screw, and the lead screw can rotate under the action of the driving member 221, so that the lead screw nut reciprocates along the axial direction of the lead screw; at the same time, along the interval direction of the two support plates 212, a through chute 101 is provided on the lead screw nut, and the first sliding member 222 passes through the chute 101 along the interval direction of the two support plates 212.

[0076] In this way, since the first sliding member 222 is slidably connected to the first guiding structure 211, the rotational freedom of the lead screw nut can be restricted by using the first sliding member 222. When the lead screw rotates forward or backward under the driving action of the driving member 221, it can drive the lead screw nut to reciprocate along the axial direction of the lead screw, and then drive the chair body 10 to reciprocate along the first guiding structure 211 (arc-shaped bracket 21) by the first sliding member 222, so as to realize the angle adjustment of the chair body 10.

[0077] In some embodiments of the present invention, the lead screw nut can be arranged between the two support plates 212 to make full use of the space between the two support plates 212 to accommodate the lead screw nut, which is beneficial to the miniaturization of the overall product.

[0078] In some embodiments, the chute 101 is a long strip-shaped through groove, and the length extension direction of the chute 101 intersects with the axial direction of the lead screw.

[0079] The sliding groove 101 is set as a long through groove, so that the first sliding member 222 has a certain degree of freedom within the sliding groove 101. In some embodiments, by setting the first guiding structure 211 as an arc, the first sliding member 222 can be directly made to slide along an arc trajectory by using the arc-shaped first guiding structure 211, thereby adjusting the angle of the chair body 10. At this time, due to the cooperation between the lead screw nut and the lead screw, the lead screw nut can only move linearly along the axial direction of the lead screw. Since the first sliding member 222 has a certain degree of freedom within the sliding groove 101, as the lead screw nut moves linearly along the axial direction of the lead screw, due to the cooperation between the first sliding member 222 and the sliding groove 101 having a certain degree of freedom, the first sliding member 222 can move within the long through groove-shaped sliding groove 101, and thus the first sliding member 222 can move along the arc-shaped first guiding structure 211, driving the chair body 10 to achieve angle adjustment.

[0080] The sliding groove 101 is set as a long through groove. A possible implementation manner is that the cross-sectional shape of the sliding groove 101 along the direction perpendicular to the interval direction of the two support plates 212 is rectangular or rounded rectangular.

[0081] In some embodiments, the driving member 221 is disposed on one side of a support plate 212 away from the other support plate 212.

[0082] The driving member 221 is disposed on one side of a support plate 212 away from the other support plate 212, that is, the driving member 221 is disposed outside the space between the two support plates 212 to better connect with the outside. In these embodiments of the present utility model, since the driving member 221 has its own power source or needs to be connected to an external power source, in this way, it is beneficial to replace and charge the power supply component of the driving member 221 or to facilitate the connection of the driving member 221 to the external power source.

[0083] In some embodiments, the transmission assembly 223 further includes a gearbox 2233, and the gearbox 2233 is disposed at the end of the arc-shaped bracket 21 close to the seat portion 11.

[0084] In these embodiments of the present utility model, the gearbox 2233 can be set to be connected to the driving member 221, that is, the gear structure inside the gearbox 2233 is connected to the output shaft of the driving member 221, so as to convert the rotational speed and torque of the motor through the internal multi-gear structure, and further provide different gears for the angle adjustment of the safety seat 100, and better control the rate of angle adjustment.

[0085] In these embodiments of the present utility model, due to the presence of the transmission 2233, the rotation driving direction of the driving member 221 can be changed by the gear set in the transmission 2233, so that the driving shaft of the driving member 221 can be arranged perpendicular to the transmission direction of the transmission assembly 223, increasing the possibility of the position design of the driving member 221, and thus can be selectively designed according to the actual situation of the vehicle.

[0086] In these embodiments of the present utility model, the transmission 2233 is arranged at the end of the arc-shaped bracket 21, and then the transmission assembly 223 can be arranged at one end of the transmission 2233 facing away from the outside, so that at least part of the structure of the transmission 2233 is in contact with the outside. In this way, it is beneficial to the installation and disassembly of the transmission 2233, and during the use of the safety seat 100, it is beneficial to the maintenance and replacement of the transmission 2233, and the reliability is better.

[0087] In some embodiments, the transmission 2233 is arranged between two support plates 212 and is respectively connected to the two support plates 212.

[0088] In these embodiments of the present utility model, by arranging the transmission 2233 between the two support plates 212, the space between the two support plates 212 can be further utilized, which is beneficial to the miniaturization of the product. At the same time, the two support plates 212 can be respectively connected to the transmission 2233 to improve the product stability of the transmission 2233.

[0089] Exemplarily, for the connection between the transmission 2233 and the support plate 212, the housing of the transmission 2233 can be detachably connected to the support plate 212 through connecting pieces such as screws, bolts or stud bolts. In this way, when the transmission 2233 needs to be disassembled, the transmission 2233 can be disassembled as a whole for maintenance or replacement; in some embodiments, it is also possible to set the housing of the transmission 2233 and the support plate 212 to be fixedly connected by welding or even integrally formed, and the side wall of the housing of the transmission 2233 close to the outside is set to be openable. When the transmission 2233 fails and needs to be repaired or replaced, the internal components of the transmission 2233 can be repaired or replaced by opening the aforementioned side wall.

[0090] In some embodiments, the arc-shaped bracket 21 further includes a second guiding structure 213, the second guiding structure 213 is arranged at one end of the arc-shaped bracket 21 close to the backrest 12, the transmission assembly 223 further includes a second sliding member 2234 connecting the backrest 12, and the second sliding member 2234 is slidably connected to the second guiding structure 213.

[0091] Similar to the first guiding structure 211, the second guiding structure 213 is used to cooperate with the first guiding structure 211 to jointly provide guiding for the sliding of the chair body 10. The second guiding structure 213 can be, but is not limited to, a guide rail or a guide groove structure. During installation, part of the structure of the transmission component 223 can be connected to the second guiding structure 213. In this way, when the driving member 221 works, at one end of the chair body 10 close to the backrest 12, the transmission component 223 can drive the chair body 10 to slide along the second guiding structure 213.

[0092] It should be noted that in these embodiments of the present utility model, the first guiding structure 211 is arranged at one end of the arc-shaped bracket 21 close to the seat part 11, and the second guiding structure 213 is arranged at one end of the arc-shaped bracket 21 close to the backrest 12. The extending directions of the two are respectively matched with the seat part 11 and the backrest 12.

[0093] Based on this, when the driving member 221 drives the first sliding member 222 to slide at the position of the seat part 11, at the other end of the chair body 10, the second sliding member 2234 can drive the backrest 12 to slide passively. At the same time, since the extending direction of the first guiding structure 211 intersects with the extending direction of the second guiding structure 213, the seat part 11 and the backrest 12 of the chair body 10 slide along different directions respectively, thereby realizing the adjustment of the angle of the chair body 10.

[0094] In some embodiments, the second guiding structure 213 can also be set as a long through groove, and the second sliding member 2234 can be a guide rod.

[0095] The structure of the second guiding structure 213 can be the same as that of the first guiding structure 211, and the structure of the second sliding member 2234 can also be the same as that of the first sliding member 222. The difference lies only in the setting position and direction, which will not be elaborated here.

[0096] Since the second sliding member 2234 needs to bear more component forces in the direction of gravity during the use of the safety seat 100, in some embodiments of the present utility model, the structural strength of the second sliding member 2234 can be set to be greater than that of the first sliding member 222.

[0097] Exemplarily, in the embodiment where both the first sliding member 222 and the second sliding member 2234 are guide rods, the cross-sectional area of the second sliding member 2234 along the axial direction can be set to be greater than the cross-sectional area of the first sliding member 222 along the axial direction; or, in some embodiments, the second sliding member 2234 can also be formed by using a material with higher structural strength. The present application does not make any limitations in this regard.

[0098] In some embodiments, the seat cushion portion 11 and the backrest portion 12 may also be integrally formed. To improve the structural consistency of the chair body 10, when the angle adjustment assembly 22 drives the chair body 10 at one end of the chair body 10, the seat cushion portion 11 and the backrest portion 12 rotate together to adjust the angle, and the reliability is better.

[0099] An embodiment of the present invention also provides a vehicle, which includes a safety seat 100 as described in any one of the foregoing embodiments.

[0100] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the technical concept of the present invention, or direct / indirect application in other related technical fields are all included in the patent protection scope of the present invention.
