Description

Technical Field

[0001] The present invention relates to the field of battery replacement, and in particular to a channel opening and closing device and a battery replacement station including the same. Background Art

[0002] In the current battery swap station technology, a counterweight is usually used to drive the lifting door at the channel entrance to move. However, there is a significant problem with this method, that is, the counterweight may interfere with the normal operation of the battery swap equipment in the channel entrance. Since the channel entrance is a key area for the movement of the battery swap equipment, the counterweight can easily move to the area where the channel entrance is located during the movement process, which may cause it to collide or interfere with the battery swap equipment, which may cause damage to the battery swap equipment or obstruction of its operation. This interference phenomenon not only affects the normal operation of the battery swap equipment at the channel entrance, but may also pose a potential threat to the efficiency and safety of the battery swap station. Therefore, the above-mentioned problems need to be solved urgently. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide a channel opening and closing device and a battery swap station including the same.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A channel opening and closing device, the channel opening and closing device includes a channel opening for battery exchange equipment to enter and exit a charging area and a lifting door capable of opening and closing the channel opening, the channel opening opening and closing device also includes an installation door frame, a stroke amplification mechanism and a counterweight, wherein the installation door frame is arranged to define the channel opening, the lifting door is transmission-connected to the counterweight through the stroke amplification mechanism and both are arranged in the installation door frame, the stroke amplification mechanism is used to amplify a first stroke of the lifting and lowering movement of the counterweight into a second stroke of the lifting and lowering movement of the lifting door, when the lifting door rises and opens the channel opening, the counterweight is located above the channel opening, and the lifting door and the counterweight are staggered along the thickness direction of the installation door frame.

[0006] In the technical solution, a travel amplification mechanism is provided to establish a transmission connection between the counterweight and the lifting door, so that the travel amplification mechanism can be used to amplify the travel, so that the lifting displacement of the counterweight can be smaller than the displacement required for opening and closing the lifting door. By reducing the lifting displacement of the counterweight, the counterweight can be installed in the door frame, and the lowering of the counterweight caused by the lifting door will not affect the normal passage of the passage.

[0007] In addition, providing a counterweight can also reduce or even balance the gravity of the lift door, reduce the driving force required to move the lift door, improve the stability of the lift door's movement, and ensure that the lift door can maintain a stable and vertical state during movement.

[0008] In addition, by staggering the lifting door and the counterweight along the thickness direction of the mounting door frame, the space in the mounting door frame can be fully utilized to achieve a compact structure, so that the space occupied by the entire passage opening and closing device can be further reduced.

[0009] Preferably, the passage opening and closing device further comprises a driving mechanism connected to the lifting door through the stroke amplification mechanism, the driving mechanism being arranged in the installation door frame, and the driving mechanism being used to drive the lifting door to move up and down;

[0010] When the lifting door rises and opens the passage opening, the driving mechanism is located above the lifting door.

[0011] In this technical solution, the driving mechanism and the counterweight are used to drive the movement of the lifting door. The counterweight can partially replace the work of the driving mechanism, thereby reducing the load of the driving mechanism, reducing its driving load, helping to reduce the power consumption of the driving mechanism, extending its service life, reducing the frequency of maintenance and replacement, and achieving energy saving to a certain extent. In addition, arranging the driving mechanism at the upper end of the passage opening helps to maximize the use of space, so that the driving mechanism can be installed more compactly in a limited vertical space.

[0012] Preferably, the counterweight is rectangular in shape, and the thickness of the counterweight is smaller than the thickness of the mounting door frame.

[0013] In the technical solution, this structural form can avoid interference between the counterweight and the movement of the lifting door, help ensure the smooth movement of the lifting door, and avoid the setting of its position affecting the normal opening and closing function of the passage. At the same time, by forming the counterweight in a rectangular shape, the counterweight can be ensured to have sufficient weight to reduce or even balance the gravity of the lifting door under the premise that the thickness of the counterweight is relatively thin.

[0014] Preferably, the counterweight and / or the driving mechanism are arranged on a side of the installation door frame facing the charging area.

[0015] In this technical solution, the drive mechanism and the counterweight are placed on one side of the charging area, that is, inside the battery swap station, which can effectively protect these key components from the influence of the external environment or other potential damage factors, help improve their stability and reliability, reduce maintenance requirements, and to a certain extent improve the aesthetics of the battery swap station.

[0016] Preferably, the stroke amplification mechanism is a pulley block, including a driving wheel arranged on the driving mechanism, a fixed pulley arranged on the installation door frame side by side with the driving mechanism, and a movable pulley arranged on the counterweight. One end of the driving chain led out from the movable pulley is connected to the installation door frame, and the other end is connected to the lifting door after passing through the fixed pulley and the driving wheel in sequence.

[0017] In this technical solution, the characteristic that a movable pulley can shorten the distance by half is utilized to reduce the moving distance of the stroke amplification mechanism after meeting the lifting amplitude of the lifting door. That is, after the lifting door moves a certain distance, the stroke amplification mechanism only needs to move half of the distance to meet the moving requirement of the lifting door, enabling the lifting door to meet the opening and closing of the passage for the movement of the battery swapping equipment under limited vertical space, improving the space utilization efficiency. At the same time, the rotation of the driving wheel arranged on the driving mechanism is used to drive the driving chain of the stroke amplification mechanism to realize the lifting of the lifting door, and the structure is simpler and more compact.

[0018] Preferably, at the crossbeam position at the upper end of the installation door frame along the height direction of the passage, there is a track extending along the moving direction of the lifting door, and the track is arranged on both sides of the counterweight to provide guidance for the lifting movement of the counterweight.

[0019] In this technical solution, the setting of the track helps to provide guidance for the movement of the counterweight, ensuring that it moves along the designed trajectory, contributing to maintaining the smooth movement of the lifting door, and reducing the swing and deviation during the movement process.

[0020] Preferably, along the height direction of the passage, at the lower end of the track, there is a horizontally extending limiting portion, and the limiting portion is used to contact the lower surface of the counterweight to limit the moving stroke of the counterweight.

[0021] In this technical solution, the setting of the limiting portion can effectively limit the moving range of the counterweight, ensuring that its movement on the track is precisely controlled, preventing the counterweight from exceeding the designed safety range during the movement of the lifting door and interfering with the normal passage of the battery swapping equipment in the passage, and helping to avoid potential damage or safety risks.

[0022] Preferably, on both sides of the installation door frame, there are sliding rails extending along the moving direction of the lifting door for the lifting door to move, and on both sides of the lifting door, there are sliders adapted to the sliding rails. The sliders are embedded in the sliding rails, and the lifting door moves along the extension direction of the sliding rails through the sliders.

[0023] In this technical solution, the design of the slide rail and the slider helps to ensure that the lifting door maintains smooth movement during movement, improves the stability of the operation of the channel opening and closing device, and prevents the lifting door from deviating from or detaching from the installation door frame during movement.

[0024] Preferably, a driving mechanism connected to the lifting door through the stroke amplification mechanism is provided on the installation door frame, and an in-place detection component is provided near the passage opening, and the in-place detection component is electrically connected to the driving mechanism;

[0025] The position of the in-place detection component on the mounting door frame is set to: when the lifting door moves to a preset position, it can contact the detection end of the in-place detection component to stop the driving mechanism from continuing to drive the stroke amplification mechanism to drive the lifting door to move.

[0026] In the present technical solution, the in-position detection component is utilized to accurately detect whether the lifting door has moved to the preset position, and the position of the lifting door is timely sent to the driving mechanism in the form of a signal, so that the driving mechanism performs the next step according to the received signal. This design helps to ensure that the lifting door can accurately stop at the desired position, improve the opening and closing accuracy of the passage opening, thereby preventing the lifting door from moving excessively, ensuring the safety performance of the passage opening and closing device, and avoiding safety hazards caused by the lifting door staying in an incorrect position.

[0027] Preferably, the in-place detection component includes a touch arm for contacting the lifting door, and a sensor connected to the touch arm and electrically connected to the driving mechanism. When the lifting door is about to open the passage opening and rises to a preset position, the lifting door will push the touch arm to move. When the lifting door opens the passage opening, the touch arm reaches its limit position and sends a stop signal to the driving mechanism through the sensor.

[0028] In this technical solution, the position of the lifting door can be accurately detected by monitoring the position of the touch arm through the sensor. And the detection of the in-place detection component is more reliable through the mechanical method of the lifting door contacting the touch arm, and the signal can be sent to the driving mechanism in time. This real-time feedback ensures that the in-place detection component monitors the position of the lifting door in a timely and accurate manner.

[0029] Preferably, the connecting end between the stroke amplification mechanism and the lifting door is arranged at the central axis of the lifting door.

[0030] In this technical solution, placing the connection end of the stroke amplification mechanism on the central axis of the lifting door can achieve balanced force transmission, which helps ensure the stable movement of the lifting door during opening and closing, reducing the uneven forces and torques it receives. Moreover, it also helps prevent the lifting door from skewing or swaying during movement, improving the reliability of movement.

[0031] A battery swapping station, which includes the channel opening and closing device described in any one of the above.

[0032] In this technical solution, the channel opening and closing device adopting the above structural form can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0033] The positive and progressive effects of the present invention are as follows:

[0034] 1. For the said channel opening and closing device, by setting up a stroke amplification mechanism to establish a transmission connection between the counterweight and the lifting door, making use of the characteristic of the stroke amplification mechanism to amplify the stroke, the lifting displacement of the counterweight can be made smaller than the displacement required for the opening and closing of the lifting door. By reducing the lifting displacement of the counterweight, the counterweight can be installed within the installation doorframe, and the descent of the counterweight caused by the ascent of the lifting door will not affect the normal passage of the channel.

[0035] 2. For the said channel opening and closing device, by setting up a counterweight, it can also reduce or even balance the gravity of the lifting door, reduce the driving force required to drive the lifting door to move, improve the stability of the lifting door movement, and ensure that the lifting door can maintain a stable and vertical state during movement.

[0036] 3. For the said channel opening and closing device, by arranging the lifting door and the counterweight to be misaligned along the thickness direction of the installation doorframe, the space within the installation doorframe can be fully utilized to achieve a compact layout of the structure, so that the space occupied by the entire channel opening and closing device can be further reduced.

[0037] 4. The battery swapping station adopting this channel opening and closing device can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0061] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0062] The present invention provides a battery swapping station for providing battery swapping services to vehicles driving into the battery swapping station. Among them, the battery swapping station includes a battery swapping area and a charging area. The area where vehicles drive in is the battery swapping area, and battery swapping equipment is provided in the battery swapping area to disassemble and assemble the batteries loaded on the vehicles. After the disassembly and assembly are completed, the battery swapping equipment will drive into the charging area through the passage opening to perform a charging operation on the battery removed from the vehicle. In order to separate the charging area and the battery swapping area while not affecting the normal driving of the battery swapping equipment, a passage opening opening and closing device is also provided at the position of the passage opening of the battery swapping station.

[0063] As Figures 1 - 5 shown, this embodiment provides a preferred structural setting scheme for the passage opening opening and closing device 100. Among them, the function of the passage opening opening and closing device 100 is to close and open the passage opening of the battery swapping station, and the switching between its open state and closed state is as Figure 1 and Figure 2 shown.

[0064] In order to solve the problem that the counterweight takes up a large space, the passage opening and closing device 100 in this embodiment is specifically provided with a mounting door frame 13, a stroke amplification mechanism 200 and a counterweight 14 in addition to the lifting door 12, wherein the mounting door frame 13 encloses the area where the passage opening 11 is located, and the lifting door 12 is connected to the counterweight 14 by a transmission through the stroke amplification mechanism 200, and the counterweight 14 and the stroke amplification mechanism 200 are both arranged in the mounting door frame 13 to avoid crowding out the external space. Among them, the weight of the counterweight 14 is configured to be able to drive the lifting door 12 to rise, and the stroke amplification mechanism 200 is used to amplify the first stroke of the lifting movement of the counterweight 14 into the second stroke of the lifting movement of the lifting door 12, that is, by setting the stroke amplification mechanism 200, the first stroke of the counterweight 14 with a smaller range of movement can be amplified into the second stroke of the lifting movement of the lifting door 12 with a larger range of movement, so that when the lifting door 12 rises and opens the passage opening 11, the counterweight 14 is located above the passage opening 11. By setting a stroke amplification mechanism 200 to construct a transmission connection between the counterweight 14 and the lifting door 12, the stroke amplification mechanism 200 can be used to amplify the stroke, so that the lifting displacement of the counterweight 14 can be smaller than the displacement required by the lifting door 12 to open and close the passage 11. By reducing the lifting displacement of the counterweight 14, the counterweight 14 can be installed in the installation door frame 13, and the descent of the counterweight 14 caused by the lifting door 12 will not affect the normal passage of the power exchange equipment in the passage 11. Among them, the stroke amplification mechanism 200 can adopt a variety of structures to achieve the purpose of stroke amplification. For example, in this embodiment, the purpose of stroke amplification is achieved by the movable pulley principle. In other embodiments, other amplification principles existing in the prior art such as the lever principle can also be used to achieve the purpose of amplification. Specifically in this embodiment, the amplification ratio generated by the movable pulley principle is 1:2, so the weight of the counterweight 14 should be configured to be twice that of the lifting door 12 to completely balance the weight of the lifting door 12. If a stroke amplification mechanism 200 with other amplification ratios is used in other embodiments, the weight of the counterweight 14 can be adjusted as needed.

[0065] In addition, the counterweight 14 can reduce or even balance the gravity of the lift door 12, reduce the driving force required to move the lift door 12, improve the stability of the movement of the lift door 12, and ensure that the lift door 12 can maintain a stable and vertical state during movement.

[0066] In addition, if Figure 5As shown, the lifting door 12 and the counterweight 14 are staggered along the thickness direction of the mounting door frame 13. Specifically, the lifting door 12 is located on the right side of the mounting door frame 13, and the counterweight 14 is located on the left side of the mounting door frame 13. When the counterweight 14 drives the lifting door 12 to move to the desired position, that is, when both move up and down along the height direction of the passage opening 11, the lifting door 12 and the counterweight 14 do not interfere with each other, and will not affect the normal opening and closing function of the lifting door 12 of the passage opening 11. In addition, by staggering the lifting door 12 and the counterweight 14 along the thickness direction of the mounting door frame 13, the space in the mounting door frame 13 can be fully utilized to achieve a compact structure arrangement, so that the space occupied by the entire passage opening and closing device 100 can be further reduced. In order to achieve the purpose of staggering the counterweight 14 and the lifting door 12 in the thickness direction of the installation door frame 13 and avoid interference between the two during the lifting process, the counterweight 14 in this embodiment is shaped like a thin plate to ensure that it has sufficient weight to balance the lifting door 12 when the thickness is small.

[0067] It should be clearly stated that, in this embodiment, Figure 1 As shown, when the lifting door 12 is in the closed state, it completely covers the passage opening 11, so as to effectively prevent people and foreign objects from invading the charging area of ​​the battery swap station, and improve the isolation effect between the charging area and the outside world, meeting the requirements of dust prevention, heat preservation, etc. Of course, in other embodiments, the lifting door 12 can also half-cover or partially cover the passage opening 11 as needed, and the specific coverage degree can be set as needed according to actual needs.

[0068] like Figures 1 - 2 and Figure 4 As shown, the passage opening and closing device 100 also includes a driving mechanism 15 that is connected to the lifting door 12 through the stroke amplification mechanism 200. The driving mechanism 15 is arranged in the installation door frame 13 to drive the lifting door 12 to move up and down. Specifically, the driving wheel of the driving mechanism 15 is engaged with the driving chain led from the stroke amplification mechanism 200, and the lifting door 12 is driven to move up by the driving motor driving the driving wheel to rotate. This solution of directly acting on the counterweight mechanism to achieve driving has a relatively simple structure and high reliability. Of course, in other embodiments, linear driving methods such as electric push rods and cylinders can also be used to achieve the lifting and moving of the lifting door.

[0069] In this embodiment, the driving mechanism 15 and the counterweight 14 are used together to drive the movement of the lifting door 12. The weight of the lifting door 12 is balanced by the counterweight 14, so that the load of the driving mechanism 15 is greatly reduced, thereby reducing its driving load, helping to reduce the power consumption of the driving mechanism 15, extending its service life, reducing the frequency of maintenance and replacement, and also achieving energy-saving effects to a certain extent.

[0070] Moreover, when the lifting door 12 rises to open the passage opening 11, the driving mechanism 15 is located above the lifting door 12. This design helps to maximize the use of space, enabling the driving mechanism 15 to be more compactly installed in the limited vertical space.

[0071] In this embodiment, both the counterweight 14 and the driving mechanism 15 are provided on the side of the installation doorframe 13 facing the charging area. By placing the driving mechanism 15 and the counterweight 14 on one side of the charging area, i.e., inside the battery swapping station, these key components can be effectively protected from the external environment or other potential damage factors, which helps to improve their stability and reliability, reduce maintenance requirements, and also improve the aesthetics of the battery swapping station to a certain extent.

[0072] As Figures 1 - 2 and Figure 4 shown, this embodiment also provides a preferred structural setting scheme for the stroke amplification mechanism 200. Specifically, it achieves the purpose of stroke amplification through the principle of movable pulleys. The stroke amplification mechanism 200 includes a driving wheel 21 provided on the driving mechanism 15, a fixed pulley 22 arranged in parallel with the driving mechanism 15 on the installation doorframe 13, and a movable pulley 23 provided on the counterweight 14. One end of the driving chain led out from the movable pulley 23 is connected to the installation doorframe 13, and the other end passes through the fixed pulley 22 and the driving wheel 21 in sequence and then is connected to the lifting door 12.

[0073] In this embodiment, by utilizing the characteristic that the movable pulley 23 can shorten the distance by half, the distance that the stroke amplification mechanism 200 needs to move can be reduced after meeting the lifting amplitude of the lifting door 12. That is, after the lifting door 12 moves a certain distance, the stroke amplification mechanism 200 only needs to move half of the distance to meet the movement requirements of the lifting door 12, enabling the lifting door 12 to meet the opening and closing requirements of the passage opening 11 for the movement of the battery swapping equipment in the limited vertical space and improving the space utilization efficiency. At the same time, the rotation of the driving wheel 21 provided on the driving mechanism 15 is used to drive the driving chain of the stroke amplification mechanism 200 to realize the lifting of the lifting door 12, and the structure is simpler and more compact.

[0074] As Figures 1 - 2 and Figure 4 shown, at the crossbeam position at the upper end of the installation doorframe 13 along the height direction of the passage opening 11, there is a track 131 extending along the moving direction of the lifting door 12. The track 131 is arranged on both sides of the counterweight 14 to provide guidance for the lifting movement of the counterweight 14.

[0075] In this embodiment, the setting of the track 131 helps to provide guidance for the movement of the counterweight 14, ensuring that it moves along the designed trajectory, which helps to maintain the smooth movement of the lifting door 12 and reduces the swing and deviation during the movement process.

[0076] Preferably, along the height direction of the channel opening 11, a horizontally extending limiting portion 132 is provided at the lower end of the track 131. The limiting portion 132 is used to contact the lower surface of the counterweight 14 to limit the moving stroke of the counterweight 14.

[0077] In this embodiment, the setting of the limiting portion 132 can effectively limit the moving range of the counterweight 14, ensure that its movement on the track 131 is precisely controlled, prevent the counterweight 14 from exceeding the designed safety range when the lifting door 12 moves, interfere with the normal passage of the battery swapping device in the channel opening 11, and help avoid potential damage or safety risks.

[0078] As Figures 1 - 2 and Figure 4 shown, slide rails 133 extending along the moving direction of the lifting door 12 are provided on both sides of the installation door frame 13 for the lifting door 12 to move, and slider blocks 121 adapted to the slide rails 133 are provided on both sides of the lifting door 12. The slider blocks 121 are adapted to the slide rails 133. Preferably, the slider blocks 121 are embedded in the slide rails 133. The lifting door 12 moves along the extending direction of the slide rails 133 through the slider blocks 121 to realize the movement of the lifting door 12 on the installation door frame 13.

[0079] In this embodiment, the design of the slide rails 133 and the slider blocks 121 helps to ensure that the lifting door 12 moves smoothly during the movement process, improves the stability of the operation of the channel opening opening and closing device 100, and avoids the lifting door 12 deviating from or disengaging from the installation door frame 13 during movement.

[0080] Preferably, the number of the slider blocks 121 is multiple and they are arranged in pairs on both sides of the lifting door 12 to balance the acting force of the movement of the lifting door 12.

[0081] As Figure 3 shown, a position-in-place detection assembly 300 is provided at the position of the installation door frame 13 close to the channel opening 11. Preferably, the position-in-place detection assembly 300 is arranged above the installation door frame 13 to detect whether the lifting door 12 rises to a preset position, and the position-in-place detection assembly 300 is electrically connected to the driving mechanism 15.

[0082] Among them, the position-in-place detection assembly 300 is arranged at the middle position of the installation door frame 13 and relatively close to the lifting door 12, so that when the lifting door 12 moves to the preset position, it can contact the detection end of the position-in-place detection assembly 300. After the position-in-place detection assembly 300 contacts the lifting door 12, a signal to stop driving is sent to the driving mechanism 15 in a signal transmission manner to stop the driving mechanism 15 from continuing to drive the stroke amplification mechanism 200 to drive the lifting door 12 to move.

[0083] In this embodiment, by using the in-place detection component 300, it is possible to accurately detect whether the lifting door 12 has moved to a preset position, and timely transmit the position of the lifting door 12 to the drive mechanism 15 in the form of a signal, so that the drive mechanism 15 can perform the next step according to the received signal. This design helps to ensure that the lifting door 12 can accurately stop at the required position, improve the opening and closing accuracy of the passage opening 11, thereby preventing the lifting door 12 from overmoving, ensuring the safety performance of the passage opening opening and closing device 100, and avoiding problems such as potential safety hazards caused by the lifting door 12 staying at an incorrect position.

[0084] Specifically, the number of the in-place detection components 300 is two, which are respectively arranged on the left and right sides of the installation door frame 13 and are both located above the lifting door 12 to perform double detection on the movement of the lifting door 12. When one side of the in-place detection component 300 fails, the position can still be detected by the in-place detection component 300 on the other side. Another advantage of setting two is to improve the accuracy of the position detection of the lifting door 12.

[0085] As Figure 3 shown, the in-place detection component 300 includes a touch arm 31 and a sensor 32. Among them, the touch arm 31 is used to contact the lifting door 12, and the sensor 32 is connected to the touch arm 31 and electrically connected to the drive mechanism 15. After the lifting door 12 opens the passage opening 11 and rises to the preset position, the lifting door 12 will push the touch arm 31 to move. When the lifting door 12 opens the passage opening 11, the touch arm 31 reaches its limit position and sends a signal to stop running to the drive mechanism 15 through the sensor 32.

[0086] In this embodiment, by monitoring the position of the touch arm 31 through the sensor 32, accurate detection of the position of the lifting door 12 can be achieved. And through the mechanical method of the lifting door 12 contacting the touch arm 31, the detection of the in-place detection component 300 is more reliable and can send a signal to the drive mechanism 15 in a timely manner. This real-time feedback ensures that the in-place detection component 300 monitors the position of the lifting door 12 in a timely and accurate manner.

[0087] As Figures 1 - 2 and Figure 4 shown, the connection end of the stroke amplification mechanism 200 and the lifting door 12 is set at the central axis of the lifting door 12. Such a setting can achieve balanced force transmission, which helps to ensure the stable movement of the lifting door 12 during the opening and closing processes, and reduces the uneven force and torque it receives. Moreover, it helps to prevent the lifting door 12 from skewing or swinging during the movement, improving the reliability of the movement.

[0088] Among them, the form of the sensor 32 can be selected as needed, such as a contact sensor 32 or a non-contact sensor 32, and there is no specific limitation.

[0089] The channel opening and closing device 100 in this embodiment is applied in a battery swapping station to open and close the channel opening of the battery swapping station. However, in other embodiments, the channel opening and closing device 100 can also be applied to other devices in the battery swapping field to achieve the purpose of reliably opening and closing the channel opening as well.

[0090] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
