Description

Technical Field

[0001] The present invention relates to the technical field of automobile sealing, in particular to a door sealing system and an automobile. Background Art

[0002] The automobile door sealing system is installed on the sheet metal around the automobile door. When the automobile door is closed, the sealing system achieves sealing by fitting with the door frame of the automobile body, playing the role of sealing, dustproofing, waterproofing, and decoratively enhancing the appearance.

[0003] With the development of society, frameless doors, with their smooth and flowing appearance, are becoming increasingly popular among consumers. Because frameless doors lack a window frame, the upper sealing strip of the door frame directly engages the door glass to form a seal. Existing sealing systems for frameless doors primarily rely on strengthening the fit between the sealing strip and the glass surface and adding interference structures to improve the sealing effect. This forcibly keeps some water out of the vehicle while directing the remaining water into the drainage channel of the door sealing structure, where it is then discharged out of the door.

[0004] However, existing frameless door sealing systems experience increased water pressure in heavy rain or high-pressure water washes, which can lead to localized seal failure and small amounts of water ingress. Furthermore, in these high-volume situations, the drainage channels of the door seal structure may not be able to drain the water in a timely manner, causing some water to accumulate at the drainage channel inlet, resulting in water accumulation at the exterior door opening. This can easily soak users' clothing when they subsequently open the door to get in or out of the vehicle, preventing a truly effective seal. Summary of the Invention

[0005] Based on this, it is necessary to provide a door sealing system and a car to address the problem that a good sealing effect cannot be truly achieved when there is a large amount of water.

[0006] A vehicle door sealing system, comprising:

[0007] a door opening sealing unit, wherein the door opening sealing unit is provided with a first water guide groove and an angle water guide groove, wherein the angle water guide groove is connected to the bottom of the first water guide groove and is used to discharge water in the first water guide groove along the vehicle frame, and the depth of the angle water guide groove gradually decreases away from the first water guide groove;

[0008] An inner water cutting unit is provided with a drainage channel therein. When the inner water cutting unit abuts against the door opening sealing unit, the drainage channel is communicated with the corner water guide groove.

[0009] The above-mentioned door sealing system is achieved by installing the door opening sealing unit on the vehicle body and the inner water cutting unit on the vehicle door, so that the door opening sealing unit can cooperate with the vehicle door glass to form a seal after the vehicle door is closed, and the corner water guide groove can be connected with the vehicle door drainage door hole through the drainage channel, so that when it rains or the vehicle is washed away, the door opening sealing unit can block part of the water outside the vehicle body and guide the other part of the water into the corner water guide groove through the first water guide groove. Part of the water in the corner water guide groove enters the drainage channel of the inner water cutting unit and is discharged through the vehicle door drainage door hole, and the other part is discharged along the vehicle frame. The entire system can discharge water in time by dispersing the water flow, avoid water accumulation, and ensure a good sealing effect when the water volume is large.

[0010] In one embodiment, the door opening sealing unit is further provided with a second water guide groove communicated with the corner water guide groove, the second water guide groove is spaced apart from the first water guide groove, and a water blocking member is provided in the second water guide groove.

[0011] In the above embodiment, the second water guide groove assists the first water guide groove in guiding water, and at the same time the water flow in the second water guide groove is buffered and diverted by the water retaining member, so that the water flow is slowed down and reduced in volume and then slowly enters the drainage channel of the inner water cutting unit, avoiding the failure of the seal due to the rapid impact of a large amount of water on the drainage channel.

[0012] In one embodiment, the corner water guide groove has a first arc-shaped portion and a second arc-shaped portion, and two ends of the first arc-shaped portion are respectively connected to the first water guide groove and the second arc-shaped portion.

[0013] In the above embodiment, the curvature of the first arc-shaped portion and the second arc-shaped portion can make the water flow more smoothly in the corner water guide groove.

[0014] In one embodiment, the center of the first arc portion is close to the second water guide groove and away from the bottom surface of the door opening sealing unit, and the center of the second arc portion is away from the second water guide groove and close to the bottom surface of the door opening sealing unit.

[0015] In the above embodiment, by making the center of the first arc-shaped portion close to the second water guide groove, the first arc-shaped portion can better receive the water discharged from the first water guide groove and the second water guide groove. By making the center of the second arc-shaped portion away from the second water guide groove, the flow directions of the water in the first arc-shaped portion and the second arc-shaped portion are different. By changing the flow direction of the water, it is ensured that the water can flow smoothly to the drainage channel and the vehicle frame.

[0016] In one embodiment, the door opening sealing unit includes a flexible substrate, a first flexible sheet and a second flexible sheet, the flexible substrate is provided with a linear protrusion structure, the first flexible sheet and the second flexible sheet are both arranged on the flexible substrate, and the first water guide groove is formed by the first flexible sheet, the flexible substrate and the linear protrusion structure, and the second water guide groove is formed by the second flexible sheet, the flexible substrate and the linear protrusion structure.

[0017] In the above embodiment, the flexibility of the flexible substrate and the first flexible sheet can ensure that when the door opening sealing unit cooperates with the vehicle door glass to form a seal, the linear protrusion structure and the first flexible sheet can abut against the vehicle door glass and produce corresponding deformation to ensure the sealing between the door opening sealing unit and the vehicle door glass.

[0018] In one embodiment, the angle between the first flexible sheet and the flexible base is an acute angle.

[0019] In the above embodiment, by making the angle between the first flexible sheet and the flexible base an acute angle, when the first flexible sheet abuts against the vehicle door glass and produces corresponding deformation, the first flexible sheet will move toward the direction close to the inside of the first water channel, thereby ensuring the first flexible sheet's shielding and intercepting effect on the water body in the first water channel.

[0020] In one embodiment, the first water guide groove and the second water guide groove are both linear grooves.

[0021] In the above embodiment, due to the straight shape of the straight groove, the first water guide groove and the second water guide groove can smoothly guide water into the corner water guide groove by utilizing the fluidics principle.

[0022] In one embodiment, the inner water cutting unit is provided with a water retaining lip, and the water retaining lip cooperates with the inner water cutting unit to form a third water guide groove. The drainage channel has a water inlet and a water outlet, and the water inlet is located in the third water guide groove.

[0023] In the above embodiment, the third water guide groove is formed by the cooperation of the water retaining lip and the inner water cutting unit, so that the water discharged through the corner water guide groove can be introduced into the drainage channel through the third water guide groove, thereby reducing the drainage pressure of the drainage channel.

[0024] In one embodiment, a water retaining boss is provided on the inner water cutting unit, a fourth water guide groove is provided on the water retaining boss, and the fourth water guide groove is connected to the water outlet.

[0025] In the above embodiment, the water is discharged into the door drainage hole through the fourth water guide channel auxiliary drainage channel.

[0026] An automobile comprises a vehicle body frame, a door frame and the above-mentioned door sealing system, wherein the door opening sealing unit is arranged on the vehicle body frame, and the inner water cutting unit is arranged on the door frame.

[0027] When it rains or when the car is washed, the above-mentioned car can block part of the water outside the car body through the door opening sealing unit, and guide the other part of the water into the corner water guide groove through the first water guide groove and the second water guide groove, so that part of the water in the corner water guide groove enters the drainage channel of the internal water cutting unit and is discharged through the door drainage door opening, and the other part is discharged along the car frame. By dispersing the water flow, the water is discharged in time to avoid water accumulation at the water inlet of the drainage channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Existing frameless door sealing systems primarily rely on strengthening the fit between the sealing strip and the glass surface and adding interference structures to improve sealing effectiveness. The sealing strip forcibly blocks some water from the vehicle while directing the remaining water into the drainage channel of the door sealing structure, which then drains the water out of the door. However, in situations such as heavy rain or car washes, the amount of water entering the drainage channel is also large, and the drainage channel may not be able to drain the water in a timely manner. This causes some water to accumulate at the drainage channel inlet, resulting in water accumulation at the outer door opening. This accumulated water can easily soak the user's clothing when opening the door to get in or out of the vehicle.

[0065] The vehicle door sealing system of the present invention provides a first water guide groove and a corner water guide groove on the original sealing strip. This allows the sealing strip to keep some water out of the vehicle while directing another portion of water through the first water guide groove into the corner water guide groove. The corner water guide groove then divides this water into two parts: one portion is directed into the drainage channel of the vehicle door sealing structure, while the other portion of water not directed into the drainage channel is discharged along the direction of the corner water guide groove and along the vehicle frame. By dispersing the water flow, water is discharged promptly, preventing water from accumulating at the water inlet of the drainage channel and causing water accumulation.

[0066] See Figure 1-Figure 2 One embodiment of the present invention provides a vehicle door sealing system, comprising a door opening sealing unit 1 and an internal water-cutting unit 2. The door opening sealing unit 1 is mounted on the vehicle body frame and is configured to form a seal with the door glass. The internal water-cutting unit 2 is mounted on the vehicle door frame and positioned below the door glass. It is configured to communicate with the door drainage opening, allowing water to be discharged out of the door through the door drainage opening. When the vehicle door is closed, the door glass abuts against the upper portion of the door opening sealing unit 1, and the internal water-cutting unit 2 abuts against the lower portion of the door opening sealing unit 1.

[0067] See Figure 3-Figure 4 The door opening sealing unit 1 is provided with a first water guide groove 14 and a corner water guide groove 15. The corner water guide groove 15 is connected to the bottom of the first water guide groove 14 and is used to discharge the water in the first water guide groove 14 along the vehicle frame.

[0068] Specifically, the first water guide groove 14 and the corner water guide groove 15 are both opened on the same side of the door opening sealing unit 1, and the top of the corner water guide groove 15 is connected to the bottom of the first water guide groove 14. The water in the first water guide groove 14 can flow into the corner water guide groove 15 under the action of gravity. The corner water guide groove 15 is arranged in an arc-shaped groove, and the depth of the corner water guide groove 15 gradually decreases in the direction away from the first water guide groove 14 until it is zero. The water can flow along the path of the corner water guide groove 15 to the vehicle body frame. Among them, the vehicle body frame has a recessed portion for accommodating and limiting the vehicle door, and the recessed portion has a connecting surface connected to the outer peripheral surface of the vehicle body frame. The bottom of the corner water guide groove 15 is located at the connecting surface, so that the water in the corner water guide groove 15 can flow to the connecting surface and be discharged to the outside of the vehicle body through the connecting surface.

[0069] See Figure 7 A drainage channel 21 is provided in the inner water cutting unit 2. When the inner water cutting unit 2 abuts against the door opening sealing unit 1, the drainage channel 21 is communicated with the corner water guide groove 15.

[0070] Specifically, the drainage channel 21 is arranged obliquely within the inner water-cutting unit 2. The drainage channel 21 has a water inlet 211 and a water outlet 212, and the distance between the water outlet 212 and the ground is less than the distance between the water inlet 211 and the ground. When the inner water-cutting unit 2 is installed on the vehicle door, the water outlet 212 communicates with the vehicle door drainage door opening, allowing water in the drainage channel 21 to be discharged to the outside of the vehicle door through the vehicle door drainage door opening. When the vehicle door is closed, the inner water-cutting unit 2 can abut against the door opening sealing unit 1, and the water inlet 211 communicates with the corner water guide groove 15, allowing water in the corner water guide groove 15 to be introduced into the drainage channel 21 through the water inlet 211.

[0071] The above-mentioned door sealing system is achieved by installing the door opening sealing unit 1 on the vehicle body frame and the inner water cutting unit 2 on the vehicle door frame, so that the door opening sealing unit 1 can cooperate with the vehicle door glass to form a seal after the vehicle door is closed, and the corner water guide groove 15 can be connected with the vehicle door drainage door hole through the drainage channel 21, so that when it rains or when washing the vehicle, the door opening sealing unit 1 can block part of the water outside the vehicle body and guide the other part of the water into the corner water guide groove 15 through the first water guide groove 14. Part of the water in the corner water guide groove 15 enters the drainage channel 21 of the inner water cutting unit 2 and is discharged through the vehicle door drainage door hole, and the other part is discharged along the vehicle frame. The entire system can discharge water in time by dispersing the water flow, avoid water accumulation, and ensure a good sealing effect when the water volume is large.

[0072] See Figure 3In one embodiment, the doorway sealing unit 1 is further provided with a second water channel 16 that communicates with the corner water channel 15. The second water channel 16 is spaced apart from the first water channel 14 and assists the first water channel 14 in conducting water. A water retaining member 3 is provided within the second water channel 16 to buffer and divert the water flow within the second water channel 16, allowing the water to flow slowly into the drainage channel 21 of the inner water cutting unit 2 after slowing down and reducing its volume. This prevents the seal from failing due to a large amount of water rapidly impacting the drainage channel 21.

[0073] Specifically, the second water guide groove 16 and the first water guide groove 14 are arranged side by side on the same side of the door opening sealing unit 1, and the second water guide groove 16 is located above the corner water guide groove 15. The bottom of the second water guide groove 16 has an arc groove 17, and the second water guide groove 16 is connected to the corner water guide groove 15 through the arc groove 17. While the door opening sealing unit 1 blocks part of the water outside the vehicle, the other part of the water can be introduced into the corner water guide groove 15 through the first water guide groove 14 and the second water guide groove 16 and the arc groove 17 respectively. The water retaining member 3 is arranged in the second water guide groove 16 and is located above the arc groove 17, so that the water in the second water guide groove 16 is first buffered by the water retaining member 3 before being introduced into the arc groove 17. It can be understood that in the present application, the water retaining member 3 is a sheet rubber structure.

[0074] In addition, see Figure 2 The first end 31 of the water stopper 3 is disposed within the second water channel 16, and the opposite second end 32 of the water stopper 3 is located outside the second water channel 16. The distance between the second end 32 of the water stopper 3 and the inner water cut unit 2 is smaller than the distance between the first end 31 of the water stopper 3 and the inner water cut unit 2. When the vehicle door is closed, the bottom surface of the water stopper 3 abuts against the top surface of the vehicle door and is inclined relative to the vehicle door, so that when the vehicle door is closed, the water stopper 3 can discharge part of the water flow in the second water channel 16 to the outside of the vehicle door.

[0075] In one embodiment, see Figure 2 The corner water channel 15 includes a first curved portion 151 and a second curved portion 152. The ends of the first curved portion 151 are connected to the first water channel 14 and the second curved portion 152, respectively. At the same height difference, a curved structure smoothes water flow more effectively than a straight structure. Therefore, the curvature of the first and second curved portions 151, 152 can smooth the flow of water within the corner water channel 15.

[0076] Specifically, the top of the first curved portion 151 communicates with the bottom of the first water channel 14, and the bottom of the first curved portion 151 communicates with the top of the second curved portion 152. The curvature of the first curved portion 151 is greater than that of the second curved portion 152. After flowing through the first water channel 14 and into the corner water channel 15, water is first decelerated by the larger-curved first curved portion 151 before flowing smoothly onto the vehicle body frame through the smaller-curved second curved portion 152.

[0077] In one embodiment, the center of the first arc-shaped portion 151 is close to the second water channel 16 and away from the bottom surface of the door opening sealing unit 1. The first arc-shaped portion 151 can better receive the water discharged from the first water channel 14 and the second water channel 16. The center of the second arc-shaped portion 152 is away from the second water channel 16 and close to the bottom surface of the door opening sealing unit 1. That is, the area where the center of the second arc-shaped portion 152 is located and the area where the center of the first arc-shaped portion 151 is located are respectively located on two sides of the corner water channel 15 that are opposite to each other. The flow direction of the water on the first arc-shaped portion 151 is different from the flow direction on the second arc-shaped portion 152. By changing the flow direction of the water, the impact of the water is dispersed, allowing the water to flow smoothly and smoothly to the drainage channel 21 and the vehicle frame.

[0078] See Figure 4 In one embodiment, the door opening sealing unit 1 includes a flexible substrate 11, a first flexible sheet 12 and a second flexible sheet 13, and a linear protrusion structure 18 is provided on the flexible substrate 11. The first flexible sheet 12 and the second flexible sheet 13 are both arranged on the flexible substrate 11. The first water guide groove 14 is formed by the first flexible sheet 12, the flexible substrate 11 and the linear protrusion structure 18, and the second water guide groove 16 is formed by the second flexible sheet 13, the flexible substrate 11 and the linear protrusion structure 18. Due to the softness of the flexible substrate 11 and the first flexible sheet 12, when the door opening sealing unit 1 cooperates with the vehicle door glass to form a seal, the linear protrusion structure 18 and the first flexible sheet 12 can both abut against the vehicle door glass and produce corresponding deformation to ensure the sealing between the door opening sealing unit 1 and the vehicle door glass.

[0079] Preferably, the flexible base 11 has an internal hollow structure to facilitate deformation. The linear protrusion structure 18, the first flexible sheet 12, and the second flexible sheet 13 are arranged side by side on the same side of the flexible base 11. The bottoms of the linear protrusion structure 18 and the first flexible sheet 12 are both curved, so that they can cooperate with the flexible base 11 to form the corner water channel 15. The first water channel 14 and the corner water channel 15 are formed by a common structure, allowing water to flow smoothly through the first water channel 14 into the corner water channel 15.

[0080] In addition, the water blocking member 3 is disposed on the second flexible sheet 13 and has a gap with the linear protrusion structure 18 , so that water in the first water channel 14 can flow into the corner water channel 15 through the gap.

[0081] In one embodiment, the angle between the first flexible sheet 12 and the flexible base 11 is an acute angle. When the first flexible sheet 12 contacts the door glass and deforms accordingly, the first flexible sheet 12 moves toward the interior of the first water channel 14, thereby ensuring that the first flexible sheet 12 has an effective shielding effect on the water in the first water channel 14.

[0082] Specifically, the orthographic projection of the first flexible sheet 12 on the flexible base 11 is located in the first water channel 14. When the first flexible sheet 12 abuts against the door glass to form a seal, the first flexible sheet 12 moves in a direction close to the first water channel 14 and can block the water flow in the first water channel 14.

[0083] See Figure 3 and Figure 4 In one embodiment, the first water channel 14 and the second water channel 16 are both linear grooves. Through the linear design of the linear grooves, the first water channel 14 and the second water channel 16 can smoothly guide water into the corner water channel 15.

[0084] The first flexible sheet 12, the flexible base 11, and the linear protrusions 18 that cooperate to form the first water channel 14 all have smooth surfaces, so that water does not encounter significant resistance when flowing in the first water channel 14. The second flexible sheet 13, the flexible base 11, and the linear protrusions 18 that cooperate to form the second water channel 16 all have smooth surfaces, so that water does not encounter significant resistance when flowing in the second water channel 16.

[0085] See Figure 5-Figure 7 In one embodiment, a water retaining lip 4 is provided on the inner water cutting unit 2, and the water retaining lip 4 cooperates with the inner water cutting unit 2 to form a third water guide groove 5. The drainage channel 21 has a water inlet 211 and a water outlet 212, and the water inlet 211 is located in the third water guide groove 5. The third water guide groove 5 formed by the water retaining lip 4 and the inner water cutting unit 2 allows the water discharged through the corner water guide groove 15 to first enter the third water guide groove 5, and then be introduced into the drainage channel 21 after transition through the third water guide groove 5. The third water guide groove 5 can act as a funnel structure to assist the drainage channel 21 in collecting water and reduce the drainage pressure of the drainage channel 21.

[0086] Specifically, the inner water cutting unit 2 has a first side surface 23 and a second side surface 24 that are opposite to each other, and the water inlet 211 opens on the first side surface 23 of the inner water cutting unit 2. The water retaining lip 4 includes a first connecting piece 41 and a second connecting piece 42, and the bottom surface of the first connecting piece 41 is connected to the first side surface 23 of the inner water cutting unit 2. The orthographic projection of the first connecting piece 41 on the inner water cutting unit 2 covers the water inlet 211, and the water body can flow into the third water guide groove 5 along the first connecting piece 41, and finally enter the drainage channel 21 through the water inlet 211. Exemplarily, the angle between the first connecting piece 41 and the first side surface is an acute angle, and the size of the first connecting piece 41 is set to be sufficient to cover the water inlet 211.

[0087] A second connecting piece 42 is also disposed on the first side surface of the inner water shear unit 2. The bottom surface of the second connecting piece 42 is connected to the first connecting piece 41, and the angle between the second connecting piece 42 and the first connecting piece 41 is obtuse. This allows the second connecting piece 42 to cooperate with the first connecting piece 41 and the inner water shear unit 2 to form a third water channel 5 with a larger volume, thereby ensuring that the third water channel 5 effectively reduces the drainage pressure of the drainage channel 21.

[0088] In one embodiment, the water inlet 211 opens into the first side surface 51 of the third water channel 5. Specifically, the third water channel 5 is formed by the water retaining lip 4 and the first side surface 23 of the inner water shear unit 2. The first side surface 51 of the third water channel 5 is a portion of the first side surface 23 of the inner water shear unit 2. Water discharged through the corner water channel 15 first enters the third water channel 5 and then enters the drainage channel 21 through the water inlet 211.

[0089] In one embodiment, the area of the water inlet 211 is smaller than the area of the first side surface 51 of the third water channel 5. By making the area of the first side surface of the third water channel 5 larger than the area of the water inlet 211, the third water channel 5 can ensure the effect of reducing the drainage pressure of the drainage channel 21 without changing the areas of the water inlet 211 and the water outlet 212.

[0090] In another embodiment, the area of the water inlet 211 is equal to the area of the first side surface 51 of the third water conduit, and the area of the water outlet 212 is smaller than the area of the water inlet 211. By maximizing the area of the water inlet 211 while ensuring that the area of the water outlet 212 remains unchanged, the capacity of the drainage channel 21 is correspondingly expanded, thereby improving the drainage effect of the drainage channel 21.

[0091] In one embodiment, the inner water cutting unit 2 is provided with a fourth water channel 61, which is connected to the water outlet 212. The fourth water channel 61 assists the drainage channel 21 in draining water into the vehicle door drainage hole.

[0092] Specifically, a water retaining boss 6 is provided on the second side surface 24 of the inner water-cutting unit 2. A fourth water channel 61 is provided on the top surface of the water retaining boss 6, and a first end of the fourth water channel 61 is connected to the water outlet 212, so that the water in the drainage channel 21 can be discharged into the fourth water channel 61 through the water outlet 212. A drain port 62 is provided on the side surface of the water retaining boss 6, and a second end opposite to the fourth water channel 61 is connected to the drain port 62. When the inner water-cutting unit 2 is installed on the vehicle door, the drain port 62 is connected to the vehicle door drainage door opening, and the water in the fourth water channel 61 can be discharged into the vehicle door drainage door opening through the drain port 62.

[0093] In addition, see Figure 7 The top surface of the water retaining projection 6 further includes a water retaining edge 63, which is adjacent to the fourth water channel 61 and connected to the second side surface 24 of the inner water cutting unit 2. After the inner water cutting unit 2 is mounted on the vehicle door frame, the side of the water retaining edge 63 away from the inner water cutting unit 2 can abut against the vehicle door frame, so that the water retaining edge 63 can shield the water in the fourth water channel 61 and assist in draining the water in the fourth water channel 61 into the vehicle door drainage hole.

[0094] An embodiment of the present application further provides an automobile, comprising a vehicle body frame, a door frame and the above-mentioned door sealing system, wherein the door opening sealing unit 1 is arranged on the vehicle body frame, and the inner water cutting unit 2 is arranged on the door frame.

[0095] Specifically, the door frame is provided with a door drainage hole communicating with the outside. After the inner water cutting unit 2 is installed on the door frame, the drainage channel 21 is connected to the door drainage hole so that the water in the drainage channel 21 can be discharged to the outside of the door through the door drainage hole.

[0096] The vehicle body frame has a recessed portion for accommodating and retaining the vehicle door. This recessed portion has a connection surface that connects to the outer periphery of the vehicle body frame. After the door opening sealing unit 1 is installed on the vehicle body frame, the bottom of the corner water channel 15 is located at this connection surface, allowing water in the corner water channel 15 to flow onto this connection surface and be discharged to the outside of the vehicle body through this connection surface.

[0097] After the door of the above-mentioned car is closed, the door opening sealing unit 1 cooperates with the door glass to form a seal, the inner water cutting unit 2 abuts against the door opening sealing unit 1, and the corner water guide groove 15 is connected with the door drainage door opening through the drainage channel 21. When it rains or the car is hit, the door opening sealing unit 1 can block part of the water outside the car body, and the first water guide groove 14 and the second water guide groove 16 guide the other part of the water into the corner water guide groove 15, so that part of the water in the corner water guide groove 15 enters the drainage channel 21 of the inner water cutting unit 1 and is discharged through the door drainage door opening on the door frame, and the other part is discharged along the door frame. By dispersing the water flow, the water is discharged in time to avoid water accumulation at the water inlet of the drainage channel 2.

[0098] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
