Description

Technical Field

[0001] This invention relates to the field of vehicle air conditioning technology, and in particular to an adjustable-angle air conditioning vent structure, method, and vehicle. Background Technology

[0002] The main function of automotive air conditioning vents is to deliver cool or hot air into the vehicle to maintain a comfortable interior temperature and improve driving and passenger comfort. Current air conditioning vents allow for airflow direction adjustment by moving a lever up and down or left and right; however, this usually involves moving the lever simultaneously to adjust the airflow direction, which limits the ability to control the air volume.

[0003] For example, existing technology discloses an air conditioning system with adjustable fan blades, including multiple fan blades that can swing up and down, and fan blades connected to levers that can swing left and right. The levers are connected to a drive motor via metal ropes. This air conditioning system also includes a detection module for detecting human position based on infrared. This solution can only achieve overall wind avoidance through human detection and is suitable for general scenarios where people are moving, but it cannot meet the personalized air supply needs of drivers in fixed sitting positions in vehicle scenarios. Existing technology also discloses a smart electric air vent, including a wind deflector, an adjustment mechanism, and a control panel. The adjustment mechanism includes a drive component and a connecting component. The drive component is electrically connected to the controller and can realize arbitrary swing adjustment at multiple angles. Although this solution can realize air vent angle adjustment, it can only realize the linkage of multiple wind deflectors and cannot independently control a single air vent. Summary of the Invention

Each first air vent deflector is connected to a set of connecting components, which are slidably connected to one side of a fixed frame. A second lifting component for pushing the connecting components is installed inside the fixed frame. The other side of the fixed frame is connected to a first lifting component. The first lifting component is used to drive each first air vent deflector to rotate synchronously, and the second lifting component is used to adjust the angle of the first air vent deflector individually.

[0006] As a further implementation, a groove is formed at one end of the first air vent deflector along its width direction, and a slider is provided in the groove. The slider is hinged to the connecting component.

[0007] As a further implementation, the connecting assembly includes a connecting rod, one end of which is slidably engaged with a guide groove in the fixing frame, and the other end of which is hinged to the slider via a hinge rod.

[0008] As a further implementation, a second lifting component is installed at set intervals in the guide groove.

[0009] As a further implementation, the first lifting component is disposed in the mounting frame, and the first lifting component includes a drive motor and a lead screw connected to the drive motor. The fixing bracket is threaded with the lead screw.

[0010] As a further implementation, the second air vent deflector is coupled to the second air vent frame via a damping bearing.

[0011] As a further implementation, a central control screen is also included, which is used to activate the first lifting component and the second lifting component according to the pressing command.

[0012] Secondly, embodiments of the present invention also provide a method for controlling an adjustable-angle air conditioning vent structure, comprising: Obtain seat parameters; The driving state is determined based on the seat parameters; among which, the driving state includes normal driving posture, relaxed posture, and forward-leaning posture. Control the angle of each first air vent deflector according to the driving status.

[0013] As a further implementation, the seat parameters include the seat back angle and the seat fore-and-aft displacement.

[0014] Thirdly, embodiments of the present invention also provide a vehicle equipped with the aforementioned air conditioning vent structure.

[0015] The beneficial effects of this invention are as follows: (1) The first air vent frame of the present invention is rotatably connected with a plurality of horizontally arranged first air vent deflectors, and the second air vent frame is rotatably connected with a plurality of vertically arranged second air vent deflectors; the first air vent deflectors can be individually controlled by the corresponding second lifting components, or can be synchronously controlled by the first lifting components to realize the function of directional air supply and meet the different sitting postures and functional requirements of the driver or passengers; the second air vent deflectors cooperate with the first air vent deflectors to realize the two-dimensional adjustment dimension of the air direction and realize the secondary optimization of airflow.

[0016] (2) The present invention utilizes the posture sensor built into the vehicle seat to extract signals such as seat angle and front and rear position to determine the driver's sitting posture, so as to adjust the angle of different air vents accordingly, adapt to the changes in air supply demand caused by changes in sitting posture, realize intelligent control of the air vent structure, and improve the comfort under different driving conditions.

[0020] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “upper,” “lower,” “front,” and “back” are used only to indicate relative positional relationships, which may change accordingly when the absolute position of the described object changes.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0022] Example 1: While existing automotive air conditioning vents allow for airflow direction adjustment via vent deflectors, most rely on a linked deflector adjustment mode, limiting airflow control. Existing improvements rely on human detection for overall airflow avoidance, only suitable for general scenarios with moving occupants, failing to meet the personalized airflow needs of drivers in fixed seating positions. Others, while enabling multi-angle vent adjustment, only allow for linked control of multiple deflectors, lacking independent control of individual vents, thus failing to meet the personalized airflow requirements of in-vehicle passengers. Therefore, this embodiment provides an adjustable-angle air conditioning vent structure with individually controllable vent deflectors, capable of meeting the different seating positions and functional requirements of drivers or passengers.

[0023] Figure 1 This is an isometric view of an adjustable-angle air conditioning vent structure provided in an embodiment of this application. Figure 2 This is a schematic diagram showing the disassembled structure of an adjustable-angle air conditioning vent provided in an embodiment of this application, as an example. Figure 1 and Figure 2 As shown, the air conditioning vent structure includes a first vent frame 1 and a second vent frame 2 arranged sequentially. The first vent frame 1 is equipped with a plurality of horizontally arranged first vent baffles 101, and the second vent frame 2 is equipped with a plurality of vertically arranged second vent baffles 201.

[0024] In this embodiment, with the direction facing the driver as the front, the second air vent frame 2 is located on the front side of the first air vent frame 1, and the two are connected by bolts 202. The first air vent deflector 101 is connected to the air vent adjustment mechanism, which allows for individual adjustment of each first air vent deflector 101 or synchronous adjustment.

[0025] In this embodiment, the first air vent frame 1 and the second air vent frame 2, which are arranged sequentially from front to back, serve as the supporting carriers. They respectively support the horizontal first air vent baffle 101 and the vertical second air vent baffle 201, forming a double-layer frame and orthogonal baffle structure, which is suitable for the narrow installation space of the vehicle air conditioning outlet and the multi-dimensional air supply needs.

[0026] Figure 3 This is a schematic diagram of the first air vent deflector in the closed state according to an embodiment of this application. Figure 4 This is a partial cross-sectional view of the first air vent deflector in the closed state provided in an embodiment of this application. Figure 5 This is a partial cross-sectional view of the first air vent deflector in the open state provided in an embodiment of this application. As an example, such as... Figures 3-5 As shown, the first air vent deflector 101 is rotatably connected to the inner side of the first air vent frame 1, and multiple first air vent deflectors 101 are arranged vertically along the first air vent frame 1. When each first air vent deflector 101 is closed, it closes the inner area of ​​the first air vent frame 1.

[0027] In the solution provided in this application embodiment, the first air outlet frame 1 is a rectangular frame, and threaded holes 103 are provided at the four corners of the first air outlet frame 1 so as to connect with the second air outlet frame 2 by means of bolts 202.

[0028] As an example, the air vent adjustment mechanism includes a first lifting component 4 and a second lifting component 5. The first lifting component 4 is used to drive each first air vent deflector 101 to rotate synchronously, and the second lifting component 5 is used to drive the corresponding first air vent deflector 101 to rotate individually.

[0029] Figure 6 This is a partial enlarged view of the first lifting component provided in an embodiment of this application, as an example, such as... Figure 6 As shown, the first lifting assembly 4 includes a drive motor 401, a mounting frame 3, a lead screw 402, a connecting plate 404, a fixing frame 405, etc. The mounting frame 3 serves as a support carrier and is located on the rear side of the first air vent frame 1. The mounting frame 3 has a vertically arranged mounting groove 301. The drive motor 401 is fixed at the top of the mounting groove 301 and is connected to the lead screw 402. A movable block 403 is mounted on the lead screw 402, and the movable block 403 is threadedly connected to the lead screw 402. The connecting plate 404 is fixed to the outside of the movable block 403.

[0030] The fixed frame 405 and the connecting plate 404 are fixedly connected. Multiple connecting components 6 are arranged along the height direction of the fixed frame 405. One end of the connecting component 6 cooperates with the fixed frame 405 through the second lifting component 5, and the other end of the connecting component 6 is connected to the first air outlet deflector 101. The drive motor 401 drives the lead screw 402 to rotate. Under the action of the threaded connection between the moving block 403 and the lead screw 402, the fixed frame 405 moves up and down with the connecting plate 404 and the moving block 403. Since the connecting component 6 and the first air outlet deflector 101 are rotatably connected, and the first air outlet deflector 101 is rotatably connected to the first air outlet frame 1 through the first rotating shaft 102, the first air outlet deflector 101 can be driven to rotate relative to the first air outlet frame 1.

[0031] In this embodiment, the first lifting assembly 4 enables synchronous adjustment of multiple sets of first air vent deflectors 101. The mounting frame 3 serves as a unified support carrier, integrating components such as the drive motor 401, lead screw 402, and moving block 403 into one unit. The mounting frame 3 is located on the rear side of the first air vent frame 1, adapting to the narrow mounting cavity of the vehicle's air conditioning vent. The first lifting assembly 4 undertakes the overall synchronous adjustment function, eliminating the need to design a separate drive structure for each set of first air vent deflectors 101, thus reducing the number of drive motors 401 and transmission components.

[0032] Figure 7 This is a partial structural diagram of the fixing frame provided in an embodiment of this application, as an example, such as... Figure 7 As shown, the fixing frame 405 is a rectangular strip structure arranged vertically. A guide groove 4051 is provided on the side of the fixing frame 405 facing the first air vent frame 1, and the extension direction of the guide groove 4051 is consistent with the length direction of the fixing frame 405. A guide block 602 is provided at one end of the connecting component 6, and the guide block 602 slides in conjunction with the guide groove 4051. The lower side of the guide block 602 is connected to the second lifting component 5, meaning that the connecting component 6 and the second lifting component 5 correspond one-to-one. The second lifting component 5 can drive the connecting component 6 to move along the guide groove 4051.

[0033] The connecting component 6 cooperates with the fixed frame 405 through the second lifting component 5. When the fixed frame 405 is raised or lowered as a whole, the second lifting component 5 moves synchronously. During single-group adjustment, the fixed frame 405 remains stationary, and the second lifting component 5 independently drives the corresponding connecting component, realizing the switching between whole-group and single-group modes. The guide groove 4051 on the fixed frame 405 provides a stable sliding trajectory for the guide block 602 of the connecting component 6, which not only ensures the consistency of the movement of the connecting component 6 during synchronous adjustment, but also provides support for precise guidance during single-group adjustment, avoiding deviation or jamming.

[0034] In the solution provided in this application embodiment, the second lifting component 5 adopts an electric lifting rod 501. It is understood that in other embodiments, the second lifting component 5 may also be implemented using other linear drive methods, such as cylinders, hydraulic cylinders, etc.

[0035] like Figure 7 As shown, the connecting assembly 6 includes a connecting rod 601, a guide block 602, and a hinge rod 603. The guide block 602 is fixed to one end of the connecting rod 601, and one end of the hinge rod 603 is hinged to the connecting rod 601, while the other end is connected to the first air vent deflector 101. Figure 8 This is a schematic diagram of the structure of the first air vent deflector 101 provided in an embodiment of this application, as an example, such as Figure 8 As shown, a groove 1011 is provided at one end of the first air vent deflector 101, and the groove 1011 is arranged along the width direction of the first air vent deflector 101. A slider 1012 is provided in the groove 1011, and a hinge seat 1013 is fixed on the outer surface of the slider 1012 corresponding to the groove 1011. The hinge seat 1013 is connected to the hinge rod 603, and the two form a hinge structure. The slider 1012 provides a connection point for the connecting assembly 6 to the first air vent deflector 101, so that the first air vent deflector 101 can be pulled to rotate relative to the first air vent frame 1 under the driving action of the second lifting assembly 5.

[0036] In the solution provided in this application embodiment, the linear pushing force of the second lifting component is converted into the rotational force of the deflector plate by means of the connecting rod 601, guide block 602, and hinge rod 603 in conjunction with the slide groove 1011, slider 1012, and hinge seat 1013 of the first air vent deflector plate 101. The double-hinged structure adapts to the angle changes of the first air vent deflector plate 101 during rotation, preventing jamming or pulling due to plate rotation. The slider 1012 is embedded in the slide groove 1011 and slides along the width direction of the first air vent deflector plate 101, preventing the hinge rod 603 from causing the first air vent deflector plate 101 to deviate or sway, ensuring that the first air vent deflector plate 101 always rotates around the first rotating shaft 102 without any shift in the center of rotation.

[0037] In the solution provided in this application embodiment, a first lifting component 4 is provided in one set and located at one end of the first air vent deflector 101; it can be understood that in other embodiments, the first lifting component 4 can also be provided in two sets, that is, a first lifting component 4 is provided at each end of the first air vent deflector 101. Under this arrangement, the number of sets of the second lifting component 4 also increases accordingly.

[0038] Figure 9 This is a partial sectional view of the second air vent frame 2 provided in an embodiment of this application, as an example, such as... Figure 9As shown, a plurality of second air vent deflectors 201 are arranged in a rectangular area inside the second air vent frame 2. The second air vent deflectors 201 are arranged vertically, and the plurality of second air vent deflectors 201 are arranged sequentially in the horizontal direction. A second rotating shaft 203 is installed at the end of the second air vent deflector 201. The second rotating shaft 203 is connected to the second air vent frame 2 through a damping bearing 204. The rotation of the second air vent deflector 201 can adjust the air direction to the left or right.

[0039] In the solution provided in this embodiment, the second air vent deflector 201 can be manually adjusted, such as... Figure 9 As shown, the second air vent deflector 201 is equipped with a lever 205, which can be pushed to open or close the second air vent deflector 201; each second air vent deflector 201 can be individually adjusted in angle. The position of the lever 205 satisfies the condition that when the second air vent deflector 201 is closed, the lever 205 does not interfere with the adjacent second air vent deflector 201. It is understood that in other embodiments, the second air vent deflector 201 can also be set to automatic adjustment, for example, driven to rotate by a motor.

[0040] During normal driving, the second air vent deflector 201 can rotate 5°~10° to the left as a whole. In order to intuitively judge the rotation angle of the second air vent deflector 201, positioning grooves are set on the damping bearing 204 at certain intervals; as an example, a damping locking point (positioning groove) is set every 5° rotation.

[0041] As an example, the first air vent deflector 101 and the second air vent deflector 201 are each provided in three groups; the uppermost first air vent deflector 101 is the first group, the middle first air vent deflector 101 is the second group, and the lowermost first air vent deflector 101 is the third group. Of course, in other embodiments, the first air vent deflector 101 and the second air vent deflector 201 can also be provided in four or more groups, depending on the coverage area of ​​the air vent.

[0042] In the solution provided in this embodiment, the first air outlet deflector 101 is used for vertical airflow control. When each first air outlet deflector 101 is closed, it can completely seal the inner area of ​​the first air outlet frame 1. Specifically, when the first air outlet deflector 101 is at 0°, it is in a closed state; when the first air outlet deflector 101 is at 10°~30°, it is in an oblique blowing state; and when the first air outlet deflector 101 is at 60°, it is in a direct blowing state.

[0043] In the solution provided in this embodiment, the action of the first air vent deflector 101 is controlled by the central control screen. The central control screen has a built-in air vent adjustment control module and communicates with the electric lifting rod 501 and the drive motor 401 via the CAN bus. The corresponding control commands are issued by operating the buttons on the central control screen.

[0044] In this embodiment, the first lifting component 4 and the second lifting component 5, together with the horizontally arranged first air vent deflector 101 and the vertically arranged second air vent deflector 201, realize the vertical and horizontal air direction control, and realize the command issuance and status feedback through the central control screen, so as to meet the needs of overall balanced air supply and personalized precise air supply.

[0045] The working principle of the adjustable-angle air conditioning vent structure in this embodiment is as follows: (1) The first lifting assembly 4 realizes the synchronous adjustment of all the first air vent deflectors 101: The central control screen issues an overall adjustment command, which is transmitted to the drive motor 401 via the CAN bus. The drive motor 401 starts and drives the lead screw 402 to rotate forward / reverse. Since the moving block 403 is threadedly connected to the lead screw 402, the rotational motion is converted into the vertical lifting motion of the moving block 403. The moving block 403 drives the connecting plate 404 and the fixed frame 405 to move up and down synchronously. All the connecting components 6 on the fixed frame 405 rise and fall together with the fixed frame 405. The hinge rod 603 of the connecting component 6 is hinged to the hinge seat 1013 of the first air vent deflector 101 through the slider 1012. When the fixed frame 405 rises and falls, the hinge rod 603 pulls the slider 1012 to slide along the slide groove 1011, thereby driving all the first air vent deflectors 101 to rotate synchronously around the first rotating shaft 102.

[0046] (2) The second lifting component 5 enables independent adjustment of a single first air vent deflector 101: The central control screen issues a single adjustment command, such as adjusting the second group of first air vent deflectors 101 to 25°. The corresponding electric lifting rod 501 starts and moves in a telescopic motion, pushing the guide block 602 of the connecting component 6 to slide vertically along the guide groove 4051 of the fixed frame 405 (the guide blocks 602 of other connecting components 6 remain fixed). The guide block 602 drives the connecting rod 601 and the hinge rod 603 to move synchronously. The hinge rod 603 pulls the slider 1012 of the corresponding first air vent deflector 101 to slide along the slide groove 1011, ultimately causing the first air vent deflector 101 of that group to rotate independently around the first rotating shaft 102, while the other first air vent deflectors 101 maintain their current angle.

[0047] During adjustment, the double hinge structure (connecting rod 601 and hinge rod, hinge rod 601 and hinge seat 1013) adapts to the angle change of the first air outlet baffle 101, and the cooperation between the slider 1012 and the slide groove 1011 limits the movement trajectory to avoid deviation and jamming.

[0048] In the solution provided in this embodiment, during overall adjustment, the electric lifting rod 501 is locked and moves synchronously with the fixed frame 405; during single-group adjustment, the first lifting component 5 remains stationary, and only the target electric lifting rod 501 moves.

[0049] In this embodiment, each of the first air vent deflectors 101 is synchronously controlled by a lead screw mechanism, which can quickly achieve overall temperature balance inside the vehicle. The lead screw mechanism adopts a longitudinal lifting transmission structure and is arranged behind the air vent, which can adapt to the narrow installation environment of the vehicle air conditioner. Each group of first air vent deflectors 101 corresponds to an electric lifting rod 501, which realizes the individual angle adjustment of each group of deflectors. The angle of a certain group of deflectors can be adjusted individually according to the different sitting postures and functional requirements of the driver or passengers, solving the problem that the overall adjustment cannot adapt to individual differences.

[0050] In this embodiment, the second air vent deflector 201 is located outside the first air vent deflector 101. The horizontally arranged first air vent deflector 101 is used for vertical adjustment and serves as a directional air supply function; the vertically arranged second air vent deflector 201 is used for horizontal adjustment and has a lateral flow diversion function, forming an orthogonal adjustment with the first air vent deflector 101; the two work together to achieve a two-dimensional adjustment dimension of airflow direction and realize secondary optimization of airflow.

[0051] Example 2: This embodiment provides a control method for an adjustable air conditioning vent structure. Based on the air conditioning vent structure described in Embodiment 1, the method uses the posture sensor built into the vehicle seat to extract signals such as seat angle and fore-and-aft position to determine the driver's sitting posture, so as to adjust the angle of different vent levers in a targeted manner to adapt to the changes in air supply demand caused by changes in sitting posture.

[0052] Specifically, seat parameters are collected: seat back angle α and seat fore-aft displacement L. Based on these parameters, seating posture types are classified, including normal driving posture, relaxed posture, and forward-leaning posture. For normal driving posture, the back angle is 90°≤α≤100°, and the fore-aft displacement L = middle position ±5cm. For relaxed posture, the back angle is 100°<α≤110°, and the seat fore-aft displacement L ≥ middle position +5cm. For forward-leaning posture, the back angle is α<90°, and the seat fore-aft displacement L ≤ middle position -5cm.

[0053] In the solution provided in this embodiment, under normal driving conditions, the angle of the first group of first air vent deflectors 101 is 10°, the angle of the second group of first air vent deflectors 101 is 25°, and the angle of the third group of first air vent deflectors 101 is 20°; under relaxed seating conditions, the angle of the first group of first air vent deflectors 101 is 0°, the angle of the second group of first air vent deflectors 101 is 15°, and the angle of the third group of first air vent deflectors 101 is 60°; under forward-leaning seating conditions, the angle of the first group of first air vent deflectors 101 is 5°, the angle of the second group of first air vent deflectors 101 is 30°, and the angle of the third group of first air vent deflectors 101 is 0°. It is understood that in other embodiments, the specific verticality of each first air vent deflector 101 angle can be adaptively adjusted according to actual conditions.

[0054] It should be noted that the above angle is the opening and closing angle relative to the closed state of the first air vent deflector 101.

[0055] In the solution provided in this embodiment, the toggle angles for the three seating postures are all individually differentiated, and each group of first air vent toggle 101 can be independently driven by the second lifting component 5. After receiving the seat sensor signal, the central control screen can directly call the preset angle combination to improve the air vent adjustment efficiency.

[0056] This embodiment uses a conventional driving posture as an example to specifically illustrate the air vent structure adjustment process: The central control screen sends independent drive commands to the three sets of electric lifting rods 501. The first set of electric lifting rods 501 retracts to a certain length below the reference stroke, adjusting the angle of the first air vent deflector 101 connected to it to 10°. The second set of electric lifting rods 501 extends to a certain length above the reference stroke, adjusting the angle of the first air vent deflector 101 connected to it to 25°. The third set of electric lifting rods 501 extends to a certain length above the reference stroke, adjusting the angle of the first air vent deflector 101 connected to it to 20°. The extension of the second set of electric lifting rods 501 is greater than that of the third set of electric lifting rods 501.

[0057] This embodiment precisely classifies three high-frequency sitting postures—driving, relaxing, and leaning forward—based on the seat back angle and fore-and-aft displacement, covering most in-vehicle states. Each set of first air vent deflectors 101 corresponds to a different opening angle in different driving states, improving user comfort. This embodiment, through targeted angle adjustments to the first air vent deflector 101 and the second air vent deflector 201, meets the airflow needs of different driving states, improving comfort in various driving conditions.

[0058] Example 3: This embodiment provides a vehicle equipped with the air conditioning vent structure described in Embodiment 1. Multiple air conditioning vent structures are provided inside the vehicle, corresponding to the left side of the driver's dashboard, the right side of the passenger's dashboard, the center of the dashboard, and the air vent position of the rear center armrest box. The driver's seat, passenger seat, and rear seats are all equipped with posture sensors, which communicate with the control modules of the corresponding air conditioning vents via a CAN bus.

[0059] In the solution provided in this embodiment, the driver's side is consistent with Embodiment 1, automatically adapting the air vent angle to the three seating positions: normal driving, relaxed, and leaning forward. A new passenger-side unoccupied detection function is added. Using a seat pressure sensor, it automatically closes the passenger-side air vent when no one is present, or links with the driver's side air vent to expand the airflow range. When rear passengers change their seating position (e.g., reclining back ≥110°), the corresponding rear air vent automatically adjusts to the relaxed mode, combined with independent rear temperature control, to enhance comfort.

[0060] As an example, different air vent angles are configured according to different scenarios, as follows: In a single-driver scenario, after the vehicle is started, the angle of the first air vent deflector 101 on the driver's side is adjusted from top to bottom to 10°, 25° and 20° respectively, while the second air vent deflector 201 is adjusted to the left to 10°.

[0061] For multi-person travel scenarios, with people in the driver's seat, front passenger seat, and rear seats, the temperature is set at 24℃ for the driver's side, 25℃ for the front passenger side, and 26℃ for the rear seats. The system links the air vents in each position: the driver's side adopts the normal driving posture adaptation angle, and the second air vent dial 201 is moved 5° to the left; the front passenger leans back to 105°, that is, relaxes the sitting posture; the rear seat backrest is adjusted to 95°, and the rear air vents are automatically adjusted to the first air vent dial 101 at an angle of 10~15° and a low wind speed to avoid direct airflow.

[0062] Therefore, this embodiment adapts to the different needs of drivers and passengers through a multi-position air vent layout and multiple seating postures.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
