Technical Field

[0001] This application relates to the field of aircraft instrument equipment, and in particular to a simulated horizon instrument. Background Art

[0002] A simulated horizon instrument is a device that can clearly display the tilt angle and attitude of a simulated aircraft to help pilots conduct simulated flight training when the pilots are on the ground for simulated flight.

[0003] A related patent with the publication number CN202855111U provides a simulated horizon instrument, which includes a housing. One end of the housing is provided with a front module and the other end is provided with a rear cover. A power board is arranged inside the housing, and a control board is electrically connected to the power board. The front module includes a front cover. An aviation socket is arranged on the rear cover, and the aviation socket is electrically connected to the power board in the housing. The rear cover is also provided with a network port and a USB interface.

[0004] When assembling the simulated horizon instrument, some parts need to be glued in the housing with hot melt adhesive, and some are fixed with bolts. When the parts inside the housing are damaged and need to be replaced, auxiliary tools are required to loosen the bolts or remove the solidified glue, which increases the maintenance cost and time. Summary of the Invention

[0005] In order to reduce the maintenance time and cost of the simulated horizon instrument, this application provides a simulated horizon instrument.

[0006] The simulated horizon instrument provided by this application adopts the following technical solution:

[0007] A simulated horizon instrument includes a housing, and the housing is composed of a bottom plate, a top plate and two side plates. A number of positioning groove groups are formed on the bottom plate and the top plate. Some of the positioning groove groups are detachably installed with positioning markers, and some of the positioning groove groups are detachably installed with plugging members.

[0008] By adopting the above technical solution, according to the parts to be installed in the housing, the required number of positioning standard parts are detachably installed on the bottom plate and the top plate. A plurality of positioning standard parts enclose the required size of the part, and the part is placed in the area enclosed by several positioning standard parts. The positioning standard parts play a role in limiting the part. At the same time, a supplementary net block is installed at one end of the part away from the bottom plate. When the top plate is covered, the supplementary net block is inserted between the corresponding four positioning standard parts, and the installation of the part is completed. The positioning standard parts realize the rapid installation of parts such as the power block and the control board in the housing. When the sizes of parts such as the power block and the control board change with iteration and update, by timely changing the positions of the positioning standard parts, the change of the size of the area enclosed by the plurality of positioning standard parts can be controlled. And when parts such as the power block and the control board need to be removed for maintenance, after removing the top plate, the parts can be directly taken out from several positioning standard parts without the need to use auxiliary tools to loosen bolts or remove solidified glue. At the same time, a plugging part is detachably installed in the positioning groove group without installing the positioning standard parts; the plugging part closes the positioning groove group, reducing the occurrence of dust blown in through the through holes on the side plate depositing in the positioning groove group.

[0009] Optionally, the positioning standard part includes a first positioning plate, a second positioning plate and a limiting elastic plate. The first positioning plate and the second positioning plate are vertically arranged. A first connecting block is arranged on the bottom wall of the first positioning plate. One end of the first connecting block away from the first positioning plate is connected to the limiting elastic plate, and the top wall area of the limiting elastic plate is larger than the bottom wall area of the first connecting block. Connecting grooves are opened on both the bottom plate and the top plate. A limiting groove is circumferentially opened on the inner side wall of the connecting groove. The top plate and the bottom plate are provided with guiding grooves on both sides of the connecting groove. The width of the guiding groove is equal to the width of the limiting groove, and the guiding groove, the limiting groove and the connecting groove communicate with each other to form a positioning groove group. The limiting elastic plate can slide into the guiding groove and be inserted into the limiting groove, and at the same time, the first connecting block is located in the connecting groove.

[0010] By adopting the above technical solution, the limiting elastic plate slides along the guiding groove by using the guiding surface and undergoes elastic deformation. At this time, the starting end of the limiting elastic plate slides through the guiding groove and enters the limiting groove until the terminal end of the limiting elastic plate also completely enters the limiting groove, and the installation of the whole positioning standard part is completed. At this time, the first connecting block is located in the connecting groove, and the first positioning plate and the second positioning plate are attached to the bottom plate or the top plate, and the installation of the positioning standard part is completed. When the position of the positioning standard part needs to be changed, the limiting elastic plate can be removed from the limiting groove. The detachable positioning standard part improves the practicability of the housing and does not need to be customized according to the size of each part.

[0011] Optionally, the blocking member includes a blocking elastic block and a protrusion, the blocking elastic block is partially inserted into the connecting groove and the limiting groove, both side walls of the blocking elastic block are provided with a first clearance groove, the distance between the bottoms of the two first clearance grooves is equal to the width of the connecting groove, and the bottom wall of the blocking elastic block is provided with a second clearance groove; the protrusion is arranged on the end wall of the blocking elastic block away from the limiting groove.

[0012] By adopting the above technical scheme, for the positioning groove group without the positioning mark inserted, the operator inserts one end of the blocking elastic block from the connecting groove, and under the giving way action of the second giving way groove, the end wall of the blocking elastic block is deformed and brought together, and when the end of the blocking elastic block close to the second giving way groove is located in the limiting groove, the deformation of the blocking elastic block is restored, and at this time the first giving way groove is located at the connecting groove, and the inner top wall of the limiting groove plays a limiting role on the blocking elastic block, and the end of the blocking elastic block away from the second giving way groove protrudes outside; when the blocking elastic block needs to be taken out of the positioning groove group, the protrusion is pushed to make the end wall of the blocking elastic block deform together and fall out of the connecting groove; the blocking elastic block closes the positioning groove group, reducing the occurrence of dust blown in from the through hole at the side panel and deposited in the positioning groove group.

[0013] Optionally, the blocking member includes a blocking plate and a reinforcement member, a second connecting block is provided at the bottom of the blocking plate, and a reinforcement plate is connected to the end of the second connecting block away from the blocking plate, and the reinforcement plate can be slid into the introduction groove and inserted into the limiting groove; the reinforcement member is located on the side of the blocking plate away from the second connecting block, and the reinforcement member reinforces the arrangement position of multiple wires.

[0014] By adopting the above technical solution, the reinforcement piece can constrain and reinforce the arrangement position of multiple wires, so that the multiple wires in the cover can be clearly classified, which is convenient for subsequent maintenance personnel to quickly distinguish them.

[0015] Optionally, the reinforcement comprises a flexible movable strip and a fixed ring, one end of the flexible movable strip is connected to the sealing plate, the side wall of the fixed ring is connected to the sealing plate, and the end of the flexible movable strip away from the sealing plate is inserted into the fixed ring; the flexible movable strip is provided with a plurality of movable blocks along its length direction, and the end of the movable block close to the sealing plate forms a limiting surface; the thickness of the movable block increases in the direction from the flexible movable strip close to the sealing plate to form a guide surface, and the fixed ring is guided by the guide surface and abuts against the limiting surface; the movable block is provided with a reset component that allows the flexible movable strip to escape from the fixed ring.

[0016] By adopting the above technical solution, when there are too many wires and classification is required, multiple wires of the same type are placed on a single sealing plate. At this time, multiple wires of the same type are located between the flexible movable strip and the fixed ring. The flexible movable strip wraps multiple wires of the same type. At this time, the end of the flexible movable strip away from the sealing plate passes through the fixed ring, so that the flexible movable strip and the fixed ring form a closed area. Continuously pull the end of the flexible movable strip, and the closed area formed by the flexible movable strip and the fixed ring gradually decreases; when maintenance of parts is required, the flexible movable strip can be disengaged from the fixed ring by using the reset member. The cooperation of the reset member and the fixed ring on the flexible movable strip can make the multiple wires in the housing clearly classified, facilitating quick distinction by later maintenance personnel.

[0017] Optionally, the reset member includes a reset rod and a reset soft strip. A reset through groove is formed in the side wall of the movable block. The reset through groove communicates with the guiding surface. The diameter of the reset through groove at the communication with the guiding surface is smaller than the maximum inner width of the reset through groove. The reset rod is inserted into the reset through groove. One end of the reset soft strip is connected to the reset rod, and the other end is attached to the guiding surface, the limiting surface and the flexible movable strip. The reset soft strip is clamped by the movable block and the fixed ring at the place where it is attached to the limiting surface.

[0018] By adopting the above technical solution, when maintenance of parts is required, before the operator takes out the parts between multiple positioning standard parts, the operator needs to pull the reset soft strip to make the reset soft strip straight. Under the action of the straight reset soft strip, the fixed ring retracts along the reset soft strip. At this time, the cut flexible movable strip disengages from the fixed ring, and multiple wires of the same type are no longer restricted; the setting of the reset soft strip also eliminates the need to borrow auxiliary tools when the wires need to be released from the restriction.

[0019] Optionally, four wire fixing rods are provided on the side wall of the first positioning plate. The four wire fixing rods are arranged along the circumferential direction of the first positioning plate, and the four wire fixing rods are inclined towards the center of the first positioning plate.

[0020] By adopting the above technical solution, when installers can insert multiple wires through the gaps between the four wire fixing rods, the four wire fixing rods can achieve basic restriction on multiple wires, reducing the occurrence of the intricate situation of multiple wires in the housing and reducing the difficulty of later maintenance.

[0021] Optionally, a retaining piece is provided on the side wall of each wire fixing rod. The retaining piece is located on one side of the wire fixing rod in the direction towards the center of the first positioning plate, and the retaining piece is inclined downwards; a retaining block is also provided at the end of the wire fixing rod away from the first positioning plate.

[0022] By adopting the above technical solution, the installer can insert multiple wires from the gaps between the four wire fixing rods and press them against the retaining plates. When the wires need to be taken out, the fixation block is pressed by hand to bend the wire fixing rods in a direction away from each other. At this time, the multiple wires lose the restriction of the retaining plates and smoothly come out from the gaps between the four wire fixing rods.

[0023] Optionally, an introduction surface is provided in the circumference of the limiting elastic plate, and the thickness of the end of the limiting elastic plate is smaller than the depth of the introduction groove.

[0024] By adopting the above technical solution and setting the introduction surface, the limiting elastic plate can enter the introduction groove more smoothly, thereby improving the convenience of operation.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the size of parts such as power blocks and control boards change with iterative updates, the position of the positioning marks can be changed in time to control the size change of the area enclosed by multiple positioning marks. When the power blocks, control boards and other parts need to be removed for maintenance, the top plate can be removed to directly take out the parts from several positioning marks without the need to use auxiliary tools to loosen the bolts or remove the solidified glue. At the same time, the sealing parts are removed and installed in the positioning slot group where the positioning marks are not installed; the sealing parts seal the positioning slot group, reducing the occurrence of dust blown in from the through holes on the side panels and deposited in the positioning slot group;

[0027] 2. The limiting elastic plate slides along the introduction groove using the introduction surface and undergoes elastic deformation. At this time, the starting end of the limiting elastic plate slides through the introduction groove into the limiting groove until the terminal end of the limiting elastic plate also completely enters the limiting groove, thus completing the installation of the entire positioning mark. At this time, the first connecting block is located in the connecting groove, the first positioning plate and the second positioning plate are attached to the bottom plate or the top plate, and the positioning mark is installed. When the position of the positioning mark needs to be changed, the limiting elastic plate can be removed from the limiting groove. The detachable positioning mark improves the practicality of the cover body, and there is no need to customize it according to the size of each part.

[0028] 3. When parts need to be repaired, the operator needs to pull the reset soft strip to straighten it before taking the parts out from between multiple positioning marks. Under the action of the straightened reset soft strip, the fixed ring retreats along the reset soft strip. At this time, the cut flexible movable strip escapes from the fixed ring, and multiple wires of the same type lose their restrictions. When the setting of the reset soft strip requires the wires to be released from restrictions, there is no need to use auxiliary tools. BRIEF DESCRIPTION OF THE DRAWINGS

A positioning standard part 3 is detachably installed in a part of the positioning groove groups 2, and a plugging part 4 is detachably installed in the other part of the positioning groove groups 2.

[0042] According to the parts to be installed in the cover 1, the required number of positioning standard parts 3 are detachably installed on the bottom plate 11 and the top plate 12 by using the positioning groove groups 2. At this time, the top plate 12 or the positioning standard parts 3 on the top plate 12 enclose the required size of the part. The part is placed in the internal space of a plurality of positioning standard parts 3, and the positioning standard parts 3 play a role in limiting the part; the positioning standard parts 3 realize the rapid installation of parts such as the power block and the control board in the cover 1. When the sizes of parts such as the power block and the control board change with iterative updates, the position of the positioning standard parts 3 is changed in time, and the size enclosed by a plurality of positioning standard parts 3 can be controlled. And when parts such as the power block and the control board need to be removed for maintenance, after removing the top plate 12, the parts can be directly taken out from a plurality of positioning standard parts 3 without using auxiliary tools to loosen the bolts or remove the solidified glue.

[0043] A plugging part 4 is detachably installed in the positioning groove group 2 that does not install the positioning standard part 3; the plugging part 4 closes the positioning groove group 2, reducing the occurrence of dust blown in through the through holes at the side plates 13 depositing in the positioning groove group 2.

[0046] Refer to Figure 3 and Figure 4, the four wire fixing rods 312 are inclined toward the center of the first positioning plate 31, and at this time, the distance between the wire fixing rod 312 and the center of the first positioning plate 31 gradually decreases in the direction of the first positioning plate 31; a fixing piece 3121 is provided on the side wall of each wire fixing rod 312, and the fixing piece 3121 is inclined downward at one end away from the wire fixing rod 312, and the fixing piece 3121 is a rigid piece. The fixing piece 3121 is located on one side of the wire fixing rod 312 toward the center of the first positioning plate 31, that is, the figure formed by the virtual connecting lines of the fixing pieces 3121 on the four wire fixing rods 312 is similar to the figure formed by the virtual connecting lines of the four wire fixing rods 312.

[0047] Reference Figure 3 and Figure 4 The wire fixing rod 312 is also integrally formed with a fixing block 3122, which is disposed at the end of the wire fixing rod 312 away from the first positioning plate 31. When the installer can insert multiple wires from the gaps between the four wire fixing rods 312 and abut against the retaining piece 3121, when the wires need to be taken out, the fixing block 3122 is pressed by hand to bend the wire fixing rods 312 in a direction away from each other, and at this time, the multiple wires are no longer restricted by the retaining piece 3121 and can be smoothly removed from the gaps between the four wire fixing rods 312.

[0048] Reference Figure 4 The bottom wall of the first positioning plate 31 is integrally formed with a first connecting block 311, and the end of the first connecting block 311 away from the first positioning plate 31 is integrally formed with a limiting elastic plate 33, the limiting elastic plate 33 is made of plastic with resilience, the limiting elastic plate 33 is horizontally arranged, the top wall area of the limiting elastic plate 33 is larger than the bottom wall area of the first connecting block 311, and the limiting elastic plate 33 is circumferentially provided with an introduction surface 331, the introduction surface 331 is arranged on the top wall of the limiting elastic plate 33, and the guide surface 4432 is an annular surface around the first connecting block 311.

[0049] Reference Figure 4 A connecting groove 21 is provided on both the bottom plate 11 and the top plate 12, and a limiting groove 22 is provided on the inner side wall of the connecting groove 21 in the circumferential direction. The bottom of the limiting groove 22 is flush with the bottom of the connecting groove 21. An introduction groove 23 is provided on both sides of the connecting groove 21 on the top plate 12 and the bottom plate 11. The thickness of the end of the limiting elastic plate 33 is less than the depth of the introduction groove 23, the width of the introduction groove 23 is equal to the width of the limiting groove 22, and the introduction groove 23, the limiting groove 22 and the connecting groove 21 are connected to form a positioning groove group 2.

[0050] The limiting elastic plate 33 slides along the introduction groove 23 using the introduction surface 331. At this time, the starting end of the limiting elastic plate 33 slides through the introduction groove 23 and enters the limiting groove 22 until the terminal end of the limiting elastic plate 33 also completely enters the limiting groove 22, thus completing the installation of the entire positioning mark 3; at this time, the first connecting block 311 is located in the connecting groove 21, and the first positioning plate 31 and the second positioning plate 32 are attached to the bottom plate 11 or the top plate 12.

[0051] Reference Figure 2 and Figure 4 After the positioning mark 3 is installed according to the size of parts such as the power block and the control board, the power block is placed between the four positioning marks 3 of the bottom plate 11. At this time, the four positioning marks 3 position the power block, that is, the first positioning plate 31 and the second positioning plate 32 are both in contact with the power block, and a supplementary mesh block 6 is provided at the end of the power block away from the bottom plate 11, and a supplementary ring 61 is provided at the end of the supplementary mesh block 6 close to the power block.

[0052] Reference Figure 4 The blocking member 4 includes a blocking elastic block 41, which is made of rubber. A portion of the blocking elastic block 41 is inserted into the connecting groove 21 and the limiting groove 22. Both side walls of the blocking elastic block 41 are provided with first clearance grooves 411. The distance between the bottoms of the two first clearance grooves 411 is equal to the width of the connecting groove 21. A second clearance groove 412 is provided on the bottom wall of the blocking elastic block 41; a protrusion 42 is integrally formed on the end wall of the blocking elastic block 41 away from the limiting groove 22.

[0053] The operator inserts the end of the blocking elastic block 41 close to the second give way groove 412 from the connecting groove 21. At this time, under the give way effect of the second give way groove 412, the end wall of the blocking elastic block 41 is deformed and brought together, and the inner side walls of the second give way groove 412 are pressed against each other. When the end of the blocking elastic block 41 close to the second give way groove 412 is located in the limiting groove 22, the deformation of the blocking elastic block 41 is restored, and the inner side walls of the second give way groove 412 are separated. At this time, the first give way groove 411 is located at the connecting groove 21. At this time, the inner top wall of the limiting groove 22 limits the blocking elastic block 41, and the end of the blocking elastic block 41 away from the second give way groove 412 protrudes outside; when it is necessary to remove the blocking elastic block 41 from the positioning groove group 2, the protrusion 42 is moved to make the end wall of the blocking elastic block 41 deform and come together to remove it from the connecting groove 21.

[0054] The implementation principle of Embodiment 1 of this application for a simulated horizon graph instrument is as follows: When installing components such as a power supply block and a control board inside the housing 1, according to the sizes of components such as the power supply block and the control board, the four positioning components 3 are installed. That is, the limiting elastic plate 33 slides along the guiding groove 23 by using the guiding surface 331, and the limiting elastic plate 33 undergoes elastic deformation. At this time, the starting end of the limiting elastic plate 33 slides past the guiding groove 23 and enters the limiting groove 22 until the terminal end of the limiting elastic plate 33 also completely enters the limiting groove 22. The limiting elastic plate 33 returns to its original state, and the inner side wall of the limiting groove 22 limits the limiting elastic plate 33, that is, the installation of the entire positioning component 3 is completed; at this time, the first connecting block 311 is located in the connecting groove 21, and the first positioning plate 31 and the second positioning plate 32 are in contact with the bottom plate 11 or the top plate 12, and the installation of the positioning component 3 is completed.

[0055] The power supply block is placed between the four positioning components 3 on the bottom plate 11. At this time, the four positioning components 3 position the power supply block, that is, both the first positioning plate 31 and the second positioning plate 32 are in contact with the power supply block. A compensating mesh block 6 is placed at one end of the power supply block away from the bottom plate 11. At this time, the compensating ring 6 is in contact with the side wall of the power supply block. At the same time, when the top plate 12 is covered, the compensating mesh block is inserted between the corresponding four positioning components 3, that is, the installation of the components and the assembly of the housing 1 are completed. And multiple wires are inserted through the gaps between the four wire fixing rods 312 and are in contact with the retaining pieces 3121 to fix the internal wires. It is only necessary to insert the plugging elastic block 41 into the unused positioning groove group 2.

[0056] When it is necessary to remove the components, the top plate 12 is removed, and the components can be directly taken out between several positioning components 3, without the need to use auxiliary tools to loosen bolts or remove solidified glue, reducing the maintenance time and cost of the simulated horizon graph instrument.

[0059] Referring to Figure 5 , the plugging member 4 includes a plugging plate 43. A second connecting block 431 is integrally formed at the bottom of the plugging plate 43. A reinforcing plate 432 is integrally formed at one end of the second connecting block 431 away from the plugging plate 43. The reinforcing plate 432 slides into the guiding groove 23 and is inserted into the limiting groove 22; a reinforcing member 44 is provided on the surface of the plugging plate 43 facing away from the second connecting block 431, and the reinforcing member 44 can constrain and reinforce the arrangement positions of multiple wires.

[0060] Referring to Figure 5, the reinforcing member 44 includes a flexible movable strip 441. The flexible movable strip 441 is made of plastic. One end of the flexible movable strip 441 is fixed to the plugging plate 43 by glue. A fixing ring 442 is also adhesively fixed on the plugging plate 43. The fixing ring 442 is made of the same material as the flexible movable strip 441, and the fixing ring 442 is arranged in contact with the connection part of the flexible movable strip 441 and the plugging plate 43.

[0061] Refer to Figure 5 and Figure 6 , a plurality of movable blocks 443 are integrally formed on the flexible movable strip 441 along its length direction. The cross-section of the movable block 443 is a right triangle, and the right triangle is perpendicular to the connection surface of the flexible movable strip 441 and the movable block 443. One end of the movable block 443 close to the plugging plate 43 forms a limiting surface 4431, that is, one right side of the right triangle is located on the flexible movable strip 441, and the surface at the other right side forms the limiting surface 4431; the thickness of the movable block 443 increases from the direction of the flexible movable strip 441 close to the plugging plate 43 to form a guiding surface 4432, that is, the surface where the hypotenuse of the right triangle is located forms the guiding surface 4432.

[0062] Refer to Figure 6 , a reset member 444 for disengaging the flexible movable strip 441 from the fixing ring 442 is arranged on the movable block 443. The reset member 444 includes a reset rod 4441. The reset rod 4441 is a round rod. A reset through groove 4433 is formed on the side wall of the movable block 443. The reset through groove 4433 communicates with the guiding surface 4432. The diameter of the reset through groove 4433 at the communicating part with the guiding surface 4432 is smaller than the maximum inner width of the reset through groove 4433, and the reset rod 4441 is press-fitted in the reset through groove 4433.

[0063] Refer to Figure 6 , a reset soft strip 4442 is adhesively connected to the reset rod 4441 near the guiding surface 4432. One end of the reset soft strip 4442 away from the reset rod 4441 is attached to the guiding surface 4432, the limiting surface 4431 and the flexible movable strip 441. The part where the reset soft strip 4442 is in contact with the limiting surface 4431 is clamped by the flexible movable strip 441 and the fixing ring 442.

[0064] The implementation principle of Embodiment 2 of this application, a simulated horizon graph instrument, is as follows: When there are too many wires and classification is required, multiple wires of the same type are placed on a plugging plate 43. At this time, multiple wires of the same type are located between the flexible movable strip 441 and the fixed ring 442. The flexible movable strip 441 wraps multiple wires of the same type. At this time, the end of the flexible movable strip 441 away from the plugging plate 43 passes through the fixed ring 442, so that a closed area is formed between the flexible movable strip 441 and the fixed ring 442. Continuously pull the end of the flexible movable strip 441 to make the closed area formed by the flexible movable strip 441 and the fixed ring 442 gradually decrease. When the flexible movable strip 441 completely adheres to the side walls of multiple wires of the same type, the fixed ring 442 adheres to the limiting surface 4431 of one of the movable blocks 443.

[0065] At this time, insert the reset rod 4441 into the next movable block 443 after the movable block 443 that is in contact with the fixed ring 442 on the flexible movable strip 441 at this time, and attach the reset soft strip 4442 to the guiding surface 4432, the limiting surface 4431 and the flexible movable strip 441. Continue to pull the flexible movable strip 441. The flexible movable strip 441 tightens the side walls of multiple wires of the same type. The fixed ring 442 moves along the guiding surface 4432 of the next movable block 443 until it abuts against the limiting surface 4431 of this movable block 443. At this time, the reset soft strip 4442 is clamped by the movable block 443 and the fixed ring 442. At this time, the operator cuts off the flexible movable strip 441 on the side of this movable block 443 away from the plugging plate 43.

[0066] When the parts need to be repaired, before the operator takes out the parts from between multiple positioning parts 3, the operator needs to pull the reset soft strip 4442 to make the reset soft strip 4442 straight. Under the action of the straight reset soft strip 4442, the fixed ring 442 retracts along the reset soft strip 4442. At this time, the cut flexible movable strip 441 comes out of the fixed ring 442, and multiple wires of the same type are no longer restricted, and the parts can be taken out smoothly. The cooperation of the reset parts 444 on the flexible movable strip 441 and the fixed ring 442 can make the multiple wires in the cover body 1 clearly classified, which is convenient for the later maintenance personnel to quickly distinguish.

[0067] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
