Description

[0002] With the development of the automobile industry, the types of vehicles have increased. Some vehicles improve the aesthetics of the vehicle by setting frameless doors. The frameless doors of existing vehicles cancel the upper window frame structure of traditional doors, and the glass directly contacts the roof or the B-pillar sealant. To ensure the sealing performance, the glass needs to increase the pre-bending amount and increase the compression load of the sealant. At the same time, during the opening and closing process of the frameless door, the glass will experience a process of slight lifting and lowering, resulting in a significant increase in the number of times the glass is lifted and lowered. Therefore, the superposition of the above factors will cause the glass of the frameless door to wear the sealant more severely.

[0003] For the sealant wear of the frameless door in the existing door assembly, the coating on the surface of the sealant is usually changed from fine particles to coarse particles, the coating thickness is increased, or the compression load is reduced, resulting in problems such as increased cost or poor sealing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0024] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0025] Specifically, the lifting movement trajectory of the light-adjusting member of the existing door assembly is usually set to rise and fall along the extension direction where the light-adjusting member fits the vehicle body frame. In this solution, the contact surface between the light-adjusting member and the seal on the vehicle body frame is a line contact. As the number of lifting operations increases, the rounded corners of the light-adjusting member will cause a line to be worn out on the seal or even cause damage, etc., resulting in a decrease in the durability and service life of the door assembly.

[0026] In view of this, the embodiments of the present application first provide a door assembly. The door assembly can be understood as the core part of the vehicle body system of the vehicle, and the door assembly can play roles such as allowing passengers to enter and exit, providing safety protection, and sound insulation and sealing.

[0027] Please refer to Figures 1-3 , Figure 1 which is a schematic structural diagram of the first embodiment of the door assembly provided by the present application, Figure 2 which is a schematic structural diagram of the second embodiment of the door assembly provided by the present application, Figure 3 is Figure 2 the enlarged schematic diagram of the structure at A in Figures 1-3 . As shown in

[0028] The vehicle body frame 10 has an opening; the light-adjusting member 20 is disposed on the vehicle body frame 10; the adjusting assembly is connected to the light-adjusting member 20, and the adjusting assembly is configured to drive the light-adjusting member 20 to move up and down relative to the vehicle body frame 10, so that the light-adjusting member 20 shields or exposes at least a part of the opening; wherein, the movement locus of the light-adjusting member 20 moving up and down relative to the vehicle body frame 10 is a first line 21a, and the shape of the cut edge where the light-adjusting member 20 fits on the vehicle body frame 10 is a second line 21b, and the first line 21a intersects with the second line 21b.

[0029] Specifically, the vehicle body frame 10 can be understood as the metal / plastic frame of the vehicle body. For example, the vehicle body frame 10 may include at least one structural member such as a first support column 11, a second support column, a third support column, a roof longitudinal beam, a floor, a sealant, etc. The vehicle body frame 10 has a door for the occupants to enter and exit, and an opening is formed on the door. The opening can be understood as the window of the door. The light-adjusting member 20 is disposed on the vehicle body frame 10 and corresponds to the opening. The light-adjusting member 20 is configured to shield or expose at least a part of the opening. The light-adjusting member 20 can realize the function of light adjustment. For example, the light-adjusting member 20 can adjust the light by adjusting at least one of the number of lights passing through the opening, the area, and the filtered wavelength light. The light-adjusting member 20 includes, but is not limited to, a window partition member made of materials such as glass, electrochromic material, suspended particle material, liquid crystal light-adjusting material, thermochromic material, photochromic material, nanocomposite material, and light-adjusting film. For example, the light-adjusting member 20 can be a window glass disposed on the vehicle body frame 10.

[0030] The adjusting assembly is connected to the light-adjusting member 20, and the adjusting assembly is configured to drive the light-adjusting member 20 to move up and down relative to the vehicle body frame 10, so that the light-adjusting member 20 rises and shields at least a part of the opening, or the light-adjusting member 20 descends and exposes at least a part of the opening. In a possible implementation manner, the adjusting assembly includes a driving member, a connecting member, and a guiding member. The light-adjusting member 20 is respectively connected to the driving member and the guiding member through the connecting member. The driving member is configured to drive the light-adjusting member 20 to move, and the guiding member is configured to guide the light-adjusting member 20 to move up and down along a preset direction.

[0031] When the dimming member 20 moves up and down relative to the vehicle body frame 10, one side of the dimming member 20 that fits against the vehicle body frame 10 has a trimming edge. When the dimming member 20 ascends, the top end of the trimming edge of the dimming member 20 gradually rises and gradually fits against the vehicle body frame 10 along the ascending movement trajectory. When the dimming member 20 descends, the top end of the trimming edge of the dimming member 20 gradually descends and gradually disengages from the vehicle body frame 10 along the descending movement trajectory. In this embodiment, when the dimming member 20 of this embodiment moves up and down, the movement trajectory of the trimming edge of the dimming member 20 is defined as the first line 21a, and the end face shape of the trimming edge of the dimming member 20 itself is defined as the second line 21b. The first line 21a intersects with the second line 21b, that is, the first line 21a and the second line 21b are not parallel.

[0032] In the embodiment of the present application, the door assembly includes a vehicle body frame 10, a dimming member 20, and an adjustment assembly; the vehicle body frame 10 has an opening; the dimming member 20 is disposed on the vehicle body frame 10; the adjustment assembly is connected to the dimming member 20, and the adjustment assembly is configured to drive the dimming member 20 to move up and down relative to the vehicle body frame 10 so that the dimming member 20 covers or exposes at least a part of the opening; wherein, the movement trajectory of the dimming member 20 moving up and down relative to the vehicle body frame 10 is the first line 21a, and the trimming edge shape of the dimming member 20 that fits against the vehicle body frame 10 is the second line 21b, and the first line 21a intersects with the second line 21b. By the above method, when the dimming member 20 of the door assembly moves up and down, the fitting depth of the dimming member 20 in contact with the vehicle body frame 10 at different height positions is different; compared with the prior art technical solution where the first line 21a and the second line 21b are parallel, the fitting depth of the prior art solution in contact with the vehicle body frame 10 at different height positions is the same, resulting in a smaller contact surface and wear area and a larger ballast. The solution of this embodiment can significantly increase the wear area of the dimming member 20 on the vehicle body frame 10 during the up and down movement, reduce the ballast when the dimming member 20 contacts the vehicle body frame 10, improve the anti-wear performance of the vehicle body frame 10 without changing the cost of the vehicle body frame 10, and thus improve the durability of the door assembly.

[0033] In one embodiment, the vehicle body frame 10 includes a first support column 11, a guide groove is provided on the first support column 11, the door assembly further includes a first seal 12, the first seal 12 is disposed in the guide groove, the dimming member 20 moves up and down relative to the vehicle body frame 10, and the first trimming edge 21 of the dimming member 20 slides along the extending direction of the guide groove and fits against the first seal 12.

[0034] Specifically, the first support pillar 11 is one of the vertical support structures of the vehicle body. The first support pillar 11 is located between the front door and the rear door of the body frame 10 and is used to connect the roof and the vehicle floor, belonging to a part of the body side frame. In a possible implementation, the body frame 10 further includes a roof rail and a second support pillar. The first support pillar 11 can be referred to as the B-pillar of the vehicle, and the second support pillar can be located on both sides of the front windshield of the body frame 10 and can be referred to as the A-pillar. The roof rail is used to connect the first support pillar 11 and the second support pillar horizontally. The door assembly of this embodiment is a frameless door, that is, the door assembly does not have an independently provided upper window frame structure, and the cut edge of the light-adjusting member 20 directly contacts the seals of the roof rail, the first support pillar 11, and the second support pillar. According to the positions where the light-adjusting member 20 contacts the seals of the body frame 10, the cut edge position of the light-adjusting member 20 can be divided into three parts: the first cut edge 21, the second cut edge 22, and the third cut edge 23. The first cut edge 21 is the right cut edge where the light-adjusting member 20 fits with the first seal 12 of the guide groove, the second cut edge 22 is the left cut edge where the light-adjusting member 20 fits with the seal of the second support pillar, and the third cut edge 23 is the upper cut edge where the light-adjusting member 20 fits with the seal of the roof rail. The adjustment assembly is connected to the lower side of the light-adjusting member 20.

[0035] In other embodiments, the body frame 10 may further include at least one of a second support pillar, a third support pillar, and a fourth support pillar; the third support pillar may be located on both sides of the rear windshield of the body frame 10 or at the rear of a sedan, and the third support pillar can be referred to as the C-pillar; the fourth support pillar may be located on both sides of the rear window of the vehicle and is used to connect the roof and the side of the body in a station wagon or an SUV, and the fourth support pillar can be referred to as the D-pillar.

[0036] Among them, the first line 21a is the movement trajectory of the first cut edge 21 when the light-adjusting member 20 moves up and down. This movement trajectory can be understood as the trajectory of a certain point on the first cut edge 21 when it moves up and down. For example, when the light-adjusting member 20 is adjusted from the fully shielded state to the fully exposed state, that is, when the light-adjusting member 20 descends in the fully closed window state and switches to the fully open window state, the highest point of the first cut edge 21 moves from the top end of the guide groove to the bottom end of the guide groove, and the movement trajectory of the highest point of the first cut edge 21 is the above-mentioned first line 21a; when the light-adjusting member 20 is adjusted from the fully exposed state to the fully shielded state, that is, when the light-adjusting member 20 ascends in the fully open window state and switches to the fully closed window state, the lowest point of the first cut edge 21 moves from the bottom end of the guide groove to the top end of the guide groove, and the movement trajectory of the lowest point of the first cut edge 21 is the above-mentioned first line 21a. The second line 21b is the end face shape of the first cut edge 21 on the right side of the light-adjusting member 20.

[0037] In this embodiment, since the first line 21a of the movement trajectory of the first cutting edge 21 intersects with the second line 21b of the first cutting edge 21, when a certain point on the first cutting edge 21 of the light regulating member 20 is at different height positions, the fitting depth in contact with the vehicle body frame 10 is different; compared with the solution where the fitting depth in contact with the vehicle body frame 10 is the same at different height positions, the solution of this embodiment can significantly increase the wear area of the light regulating member 20 on the first seal 12 during the lifting movement, reduce the ballast when the light regulating member 20 contacts the first seal 12, improve the anti-wear performance of the first seal 12 without changing the cost of the vehicle body frame 10, and thus improve the durability of the door assembly.

[0038] Wherein, the first seal 12 generally has elasticity. The thickness of the first seal 12 when no external force acts on it is defined as the third value. When the first cutting edge 21 of the light regulating member 20 fits with the first seal 12, the first seal 12 receives the external force provided by the light regulating member 20 and deforms. The thickness of the first seal 12 under the pressing action of the light regulating member 20 is defined as the fourth value. The above-mentioned fitting depth of the light regulating member 20 in contact with the vehicle body frame 10 can be understood as the difference between the third value and the fourth value, that is, it represents the depth of the light regulating member 20 pressed into the first seal 12.

[0039] Optionally, when the light regulating member 20 completely covers the opening, the shape of the cutting edge on the side of the first seal 12 away from the guide groove is the third line 12a, and the second line 21b is parallel to the third line 12a.

[0040] Specifically, one side surface of the first seal 12 fits with the inner wall of the guide groove, the other side surface of the first seal 12 faces away from the guide groove, and the light regulating member 20 fits with the side surface of the first seal 12 away from the guide groove. The shape of the cutting edge on the side of the first seal 12 away from the guide groove is the third line 12a, and the second line 21b is parallel to the third line 12a, so that the first seal 12 can completely fit with the cutting edge of the light regulating member 20, ensuring the sealing effect of the door assembly.

[0041] Optionally, when the light regulating member 20 completely covers the opening, the lowest point of the cutting edge of the light regulating member 20 in contact with the first seal 12 coincides with the intersection point of the first line 21a and the second line 21b.

[0042] Specifically, when the light-dimming member 20 completely shields the opening, that is, when the light-dimming member 20 is in the fully closed state of the window, the lowest point of the cutting edge of the light-dimming member 20 is the point where the first cutting edge 21 of the light-dimming member 20 contacts the bottommost end of the guide groove. Alternatively, the height between any point on the contact surface of the first cutting edge 21 of the light-dimming member 20 and the first seal 12 and the opening horizontal line (window horizontal line) is defined as the first height. The lowest point of the cutting edge can be understood as the point on the first cutting edge 21 where the first height is the smallest. Among them, the first line 21a and the second line 21b intersect, and there is a first intersection point between the first line 21a and the second line 21b. When the light-dimming member 20 completely shields the opening, the lowest point of the cutting edge coincides with the first intersection point.

[0043] Furthermore, the highest point of the cutting edge where the light-dimming member 20 contacts the first seal 12 coincides with the intersection point of the third line 12a and the second line 21b.

[0044] Specifically, the highest point of the cutting edge of the light-dimming member 20 is the point where the first cutting edge 21 of the light-dimming member 20 contacts the topmost end of the guide groove. Alternatively, the highest point of the cutting edge can be understood as the point on the first cutting edge 21 where the first height is the largest. There is a second intersection point between the second line 21b and the third line 12a, and the highest point of the cutting edge coincides with the second intersection point. When the light-dimming member 20 completely shields the opening, the first cutting edge 21 is completely attached to the first seal 12. Since the lowest point of the cutting edge coincides with the first intersection point and the highest point of the cutting edge coincides with the second intersection point, that is, both ends of the first line 21a intersect with the second line 21b and the third line 12a respectively. When the movement trajectory of the first cutting edge 21 during the lifting movement is decomposed, it can be obtained that the first cutting edge 21 moves linearly along its extending direction and translates along the window horizontal line.

[0045] Therefore, during the process of the light-dimming member 20 switching from the fully closed state of the window to the fully open state of the window, the highest point of the cutting edge of the first cutting edge 21 gradually moves upward from the position of the window horizontal line and contacts the topmost end of the guide groove. During the movement, different points on the first cutting edge 21 with different first heights need to be laterally pressed into the first seal 12, so that the wear areas of different points on the first cutting edge 21 with different first heights on the first seal 12 are different. Here, the highest point of the cutting edge of the first cutting edge 21 when the light-dimming member 20 completely shields the opening is defined as the third point, the lowest point of the cutting edge of the first cutting edge 21 is defined as the first point 21c, and the highest point of the cutting edge of the first cutting edge 21 when the light-dimming member 20 completely exposes the opening is defined as the second point 21d (when the light-dimming member 20 completely exposes the opening, the highest point of the cutting edge of the first cutting edge 21 and the lowest point of the cutting edge of the first cutting edge 21 almost or completely coincide); when the light-dimming member 20 completely shields the opening, the wear surface of the first cutting edge 21 on the first seal 12 is the area surface composed of the first point 21c, the second point 21d, and the third point.

[0046] As can be seen from the above method, when a certain point on the first cutting edge 21 of the light-dimming member 20 in this embodiment is at different height positions, the fitting depth of contact with the vehicle body frame 10 is different. Compared with the prior art solution in which the light-dimming member 20 is in line contact with the first sealing member 12, the solution of this embodiment adjusts the movement trajectory of the light-dimming member 20, so that the contact surface of the first cutting edge 21 of the light-dimming member 20 with the first sealing member 12 is the regional surface composed of the above-mentioned first point 21c, second point 21d and third point, significantly increasing the wear area of the light-dimming member 20 on the vehicle body frame 10 during the lifting movement, reducing the ballast when the light-dimming member 20 contacts the vehicle body frame 10, improving the anti-wear performance of the vehicle body frame 10 without changing the cost of the vehicle body frame 10, and further improving the durability of the door assembly.

[0047] Optionally, when the light-dimming member 20 completely shields the opening, the lowest point of the cutting edge of the light-dimming member 20 in contact with the first sealing member 12 is the first point 21c; when the light-dimming member 20 completely reveals the opening, the highest point of the cutting edge of the light-dimming member 20 in contact with the first sealing member 12 is the second point 21d, and the first point 21c does not coincide with the second point 21d.

[0048] Specifically, the second point 21d may be located on the side of the first point 21c away from the first sealing member 12, or the first point 21c may be located on the side of the second point 21d close to the first sealing member 12. The first point 21c does not coincide with the second point 21d. When the light-dimming member 20 completely reveals the opening, the adjusting assembly drives the light-dimming member 20 to move upward, and the light-dimming member 20 moves along the trajectory of the first line 21a. During the movement, the point where the first cutting edge 21 intersects the window horizontal line moves horizontally in the direction close to the first point 21c, so that the light-dimming member 20 is horizontally pressed into the first sealing member 12 during the movement and realizes the fitting contact with the first sealing member 12, so as to increase the contact surface of the light-dimming member 20 with the first sealing member 12 during the lifting movement.

[0049] In other possible embodiments, the distance between the highest point of the cutting edge of the light-dimming member 20 in contact with the first sealing member 12 and the window horizontal line may be defined as the second height. During the upward movement of the light-dimming member 20, the second height gradually increases, and the lowest point of the cutting edge of the light-dimming member 20 in contact with the first sealing member 12 moves from the second point 21d to the first point 21c; during the downward movement of the light-dimming member 20, the second height gradually decreases, and the lowest point of the cutting edge of the light-dimming member 20 in contact with the first sealing member 12 moves from the first point 21c to the second point 21d.

[0050] Optionally, when the light-dimming member 20 completely shields the opening, the lowest fitting depth of the cutting edge of the light-dimming member 20 in contact with the first seal 12 is a first value; when the light-dimming member 20 completely exposes the opening, the highest fitting depth of the cutting edge of the light-dimming member 20 in contact with the first seal 12 is a second value, and the first value is greater than the second value.

[0051] Specifically, the above-mentioned fitting depth can be understood as the depth at which the first cutting edge 21 of the light-dimming member 20 is pressed into the first seal 12. When the light-dimming member 20 completely shields the opening, the first value can be understood as the depth at which the first point 21c is pressed into the first seal 12; when the light-dimming member 20 completely exposes the opening, the second value can be understood as the depth at which the second point 21d is pressed into the first seal 12. The first value and the second value are different, that is, during the upward movement of the light-dimming member 20, the highest point of the first cutting edge 21 moves along the trajectory of the first line 21a. As the second height increases, the fitting depth of the lowest point of the cutting edge in contact with the first seal 12 gradually increases from the second value until it reaches the first value.

[0052] In this embodiment, since the depth at which the first point 21c is pressed into the first seal 12 is different from the depth at which the second point 21d is pressed into the first seal 12, it means that during the lifting movement of the light-dimming member 20, the wear position of the first cutting edge 21 and the first seal 12 is non-linear, so as to increase the wear area of the light-dimming member 20 on the first seal 12 during the lifting movement and reduce the ballast when the light-dimming member 20 is in contact with the first seal 12, and improve the anti-wear performance of the first seal 12 without changing the cost of the body frame 10, thereby improving the durability of the door assembly.

[0053] Optionally, the fitting depth of the light-dimming member 20 and the first seal 12 decreases as the height of the cutting edge of the light-dimming member 20 in contact with the first seal 12 increases.

[0054] Specifically, the height of the cutting edge where the light-adjusting member 20 contacts the first seal 12 can be understood as the height of the highest point of the first cutting edge 21 relative to the window horizontal line, and the fitting depth of the light-adjusting member 20 with the first seal 12 can be understood as the depth at which the corresponding highest point on the first cutting edge 21 is pressed into the first seal 12. When the light-adjusting member 20 rises relative to the vehicle body frame 10, the height of the cutting edge where the light-adjusting member 20 contacts the first seal 12 increases, and the fitting depth corresponding to the highest point decreases. When the light-adjusting member 20 descends relative to the vehicle body frame 10, the height of the cutting edge where the light-adjusting member 20 contacts the first seal 12 decreases, and the fitting depth corresponding to the highest point increases. When the light-adjusting member 20 rises relative to the vehicle body frame 10, the height of the cutting edge where the light-adjusting member 20 contacts the first seal 12 increases, and the fitting depth corresponding to the highest point decreases. When the light-adjusting member 20 completely covers the opening, that is, the highest point of the first cutting edge 21 corresponds to the third position point 21e, the fitting depth corresponding to the third position point 21e is the smallest, the lowest point of the first cutting edge 21 corresponds to the first position point, and the fitting depth corresponding to the first position point is the largest; when the light-adjusting member 20 completely exposes the opening, that is, the highest point of the first cutting edge 21 corresponds to the second position point, the fitting depth corresponding to the second position point is the smallest.

[0055] Through the above method, during the lifting movement of the light-adjusting member 20, the contact position of the first cutting edge 21 with the first seal 12 is a surface contact, which significantly increases the wear area of the light-adjusting member 20 on the first seal 12 during the lifting movement, reduces the ballast when the light-adjusting member 20 contacts the first seal 12, improves the anti-wear performance of the first seal 12 without changing the cost of the vehicle body frame 10, and further improves the durability of the door assembly.

[0056] The embodiment of the present application also proposes a lifting control method for the light-adjusting member 20, and this lifting control method can be applied to the door assembly of any of the above embodiments. Please refer to Figure 4 , Figure 4 which is a schematic flowchart of an embodiment of the lifting control method provided by the present application. As Figure 4 shown, this lifting control method includes the following steps:

[0057] Step S10: Receive a window lifting signal.

[0058] Specifically, when the window lifting control button of the vehicle is triggered, the vehicle control system can generate a window lifting signal to achieve the lifting control of the window.

[0059] Step S20: In response to the window lifting signal indicating that the light-adjusting member 20 rises, drive the light-adjusting member 20 to move upward along the first line 21a, so that at least a part of the light-adjusting member 20 fits the first seal 12 of the door assembly, and the light-adjusting member 20 covers at least a part of the opening.

[0060] After receiving the window lifting signal, in response to the window lifting signal indicating that the dimming member 20 rises, drive the optical member to move relative to the body frame 10 of the door assembly and move upward along the first line 21a, so that at least part of the dimming member 20 fits the first seal 12 of the door assembly, and the dimming member 20 shields at least part of the opening, so as to partially shield or adjust the light passing through the opening through the dimming member 20.

[0061] Step S30: In response to the window lifting signal indicating that the dimming member 20 descends, drive the dimming member 20 to descend along the first line 21a, so that at least part of the dimming member 20 disengages from the first seal 12, and the dimming member 20 exposes at least part of the opening.

[0062] When the window lifting signal indicates that the dimming member 20 descends, drive the optical member to move relative to the body frame 10 of the door assembly and move downward along the first line 21a, so that at least part of the dimming member 20 disengages from the first seal 12, and the dimming member 20 exposes at least part of the opening, so as to increase the opening area and increase the light passing through the opening, facilitating the user to observe through the opening.

[0063] Wherein, the shape of the cutting edge of the dimming member 20 fitting the first seal 12 is the second line 21b, and the first line 21a intersects the second line 21b. When the dimming member 20 moves up and down, the fitting depth of the dimming member 20 in contact with the body frame 10 at different height positions is different, significantly increasing the wear area of the dimming member 20 on the body frame 10 during the lifting movement and reducing the ballast when the dimming member 20 contacts the body frame 10, improving the anti-wear performance of the body frame 10 without changing the cost of the body frame 10, and further improving the durability of the door assembly.

[0064] The embodiment of the present application also proposes a vehicle, which includes the door assembly of any one of the above embodiments. The vehicle can be, but is not limited to, new energy vehicles, electric vehicles, internal combustion engine vehicles, hybrid vehicles and other types of vehicles.

[0065] The above is only the implementation mode of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
