Figure 2 The limiting protrusion 312 is configured to be inserted into the limiting opening 206 (in Figure 2 .

[0051] Figure 4A Yes Figures 1A-1C The enlarged view of the locking device 120 shown in FIG. 1 is used to more clearly illustrate the specific structure of the locking device 120. Figure 4A As shown, the locking device 120 includes a locking rod 421, which extends a certain length to form an elongated shape. The locking device 120 also includes a locking portion 422 disposed at the distal end of the locking rod 421, and an eccentric device receiving portion 423 disposed at the proximal end of the locking rod 421. The locking portion 422 is formed in a hook shape, one end of which is connected to the locking rod 421, and the other end forms a locking pin 428. The eccentric device receiving portion 423 is generally formed in an inverted U shape, which includes two side walls 431, 433, and a top wall 432 connected to the tops of the two side walls 431, 433. A receiving groove 435 is formed between the two side walls 431, 433 of the eccentric device receiving portion 423. One of the side walls 431 of the eccentric device receiving portion 423 is connected to the locking rod 421.

[0052] The locking device 120 further includes an elastic device 425 and a sleeve rod 426 for supporting the elastic device 425. One end of the sleeve rod 426 is connected to the side of the eccentric device receiving portion 423 connected to the locking rod 421, and the other end of the sleeve rod 426 is a free end. The sleeve rod 426 extends substantially parallel to the locking rod 421. The elastic device 425 is, for example, a spring 425. The spring 425 is sleeved on the sleeve rod 426.

[0053] Figure 4B yes Figure 1A FIG. 1 is a partial enlarged view of the front side of the flip cover assembly 100, which is used to more clearly illustrate the assembly relationship between the locking device 120 and the base 101. Figure 4BAs shown, the locking rod 421 of the locking device 120 is installed in the support structure 260 on the front side of the base 101. Specifically, the locking rod 421 is installed in the guide grooves 263, 264 of the two bosses 261, 262 of the support structure 260, and can reciprocate in the guide grooves 263, 264. When the locking rod 421 is placed in the guide grooves 263, 264, the flange 266 of the lug 265 can abut the locking rod 421 from the top, so that the movement of the locking rod 421 in the guide grooves 263, 264 is more stable, and the slender locking rod 421 is not easily deformed during the movement. The free end of the sleeve rod 426 is inserted into the guide groove 267 of the boss 261. The size of the opening of the guide groove 267 is configured so that the sleeve rod 426 can be inserted, but the spring 425 cannot be inserted, so that one end of the spring 425 on the sleeve rod 426 abuts against the boss 261, and the other end abuts against the eccentric device receiving portion 423. The spring 425 can apply a biasing force toward the proximal end (i.e., toward the direction of the eccentric device receiving portion 423) to the locking rod 421, so that the locking rod 421 can be moved from the release position to the locking position.

[0054] The locking portion 422 is turned from the front side of the base 101 to the left side of the base 101, so that the locking pin 428 of the locking portion 422 can be inserted into the through hole 207 of the lock cover 213 on the base 101. The locking rod 421 can move between the release position and the lock position by the reciprocating movement of the locking rod 421 in the guide grooves 263, 264, wherein when the locking rod 421 is in its lock position and the flip cover 110 is closed, the locking rod 421 can lock the flip cover 110 by its locking pin 428, and when the locking rod 421 is in its release position, it can release the flip cover 110. The eccentric device receiving portion 423 can cooperate with the driving device 140 to enable the locking rod 421 to reciprocate in the guide grooves 263, 264, which will be combined later. Figure 7 Detailed description.

[0055] Figure 4C yes Figure 1A The partial cross-sectional enlarged view of the dotted frame A in FIG. 1 is used to more clearly illustrate the matching relationship between the locking portion 422 of the locking device 120 and the flip cover 110 and the base 101. Figure 4CAs shown, after closing the flip cover 110, when the locking rod 421 is in its locking position, the locking pin 428 of the locking rod 421 can be inserted from the through hole 207 of the lock cover 213 on the base 101 into the locking channel 215 and the locking hole 315 of the flip cover 110 located in the locking channel 215, thereby locking the flip cover 110 on the base 101, so that the flip cover 110 is locked in the closed position. Before opening the flip cover 110, the locking rod 421 can be moved distally to its release position, so that the locking pin 428 of the locking rod 421 withdraws from the locking hole 315 of the flip cover 110 and the locking channel 215 of the base 101, thereby releasing the flip cover 110 from the base 101, so that the flip cover 110 can be opened.

[0056] Figure 5A and 5B Yes Figures 1A-1C The enlarged view of the rocker arm 130 shown in FIG. 1 is used to more clearly illustrate the specific structure of the rocker arm 130 . Figure 5A FIG. 2 shows a schematic diagram of the three-dimensional structure of the rocker arm viewed from the front. Figure 5B A schematic diagram of the three-dimensional structure of the rocker arm viewed from the reverse side is shown.

[0057] like Figure 5A-5B As shown, the rocker arm 130 includes a meshing portion 531 , which is generally fan-shaped and has teeth on its outer circumference. The meshing portion 531 is configured to cooperate with the driving device 140 , so that the rocker arm 130 can be driven by the driving device 140 to rotate.

[0058] The rocker arm 130 further includes a rocker arm shaft 532, one end of which is connected to the fan-shaped top end of the meshing portion 531. The other end of the rocker arm shaft 532 can be inserted into the rocker arm mounting hole 217 on the mounting portion 220 of the base 101 and the mounting hole 175 on the hinge portion 173 of the hinge 170 accommodated in the mounting portion 220. The rocker arm shaft 532 is configured to be fixedly connected to the hinge 170 after being inserted into the mounting hole 175 of the hinge 170, so that the flip cover 110 can be driven to open or close by the rotation of the rocker arm shaft 532. The rocker arm shaft 532 can be fixedly connected to the hinge 170 in various ways, such as a bayonet connection or a snap connection.

[0059] The rocker arm 130 further includes a torsion spring 533. One end of the torsion spring 533 is fixed to one side of the meshing portion 531 connected to the rocker arm shaft 532, and the other end of the torsion spring 533 is configured to be fixed to the base 101. When the flip cover 110 is in the closed position, the torsion spring 533 provides a pre-tightening force, so that the flip cover 110 can be kept in the closed position and fit tightly with the top of the housing 210.

[0060] Figure 6 Yes Figures 1A-1CThe enlarged view of the driving device 140 shown in FIG. 1 is used to more clearly illustrate the specific structure of each component of the driving device 140 and the assembly relationship of each component. Figure 6 As shown, the driving device 140 includes a gear 641 and an eccentric device 642. The driving device 140 also includes a driving shaft 643, and the gear 641 and the eccentric device 642 are relatively arranged on the driving shaft 643 and can rotate with the rotation of the driving shaft 643.

[0061] Specifically, the drive shaft 643 can pass through the drive opening 151 (such as Figure 1C 641 and eccentric device 642, so that the gear 641 and eccentric device 642 can be driven to rotate. The two ends of the drive shaft 643 extend from the two sides of the motor 150 and are respectively connected to the gear 641 and the eccentric device 642, so that the gear 641 and the eccentric device 642 can be driven to rotate together. In the illustrated embodiment, one end of the drive shaft 643 passes through the center of the gear 641 and is connected to the gear 641. A square hole 658 is provided at the rotation center of the eccentric device 642, and the shape of the other end of the drive shaft 643 is manufactured to be a square corresponding to the square hole. By inserting the other end of the drive shaft 643 into the square hole 658 of the gear eccentric device 642, the eccentric device 642 can be prevented from rotating relative to the drive shaft 643. Thus, the drive shaft 643 can drive the gear 641 and the eccentric device 642 to rotate together. In some embodiments, the drive shaft 643 can also be formed integrally with the gear 641 or the eccentric device 642.

[0062] A portion of the outer circumference of the gear 641 is provided as a toothed portion 652 that can mesh with the meshing portion 531 of the rocker arm 130 . Another portion of the outer circumference of the gear 641 is provided as a smooth portion 654 that does not mesh with the meshing portion 531 of the rocker arm 130 .

[0063] The eccentric device 642 has a working portion 644 which is eccentrically arranged with respect to the rotation center of the eccentric device 642. A protrusion 646 is provided on one side of the working portion 644. The protrusion 646 is provided on the side of the eccentric device 642 opposite to the gear 641.

[0064] Figure 7 Shows Figure 1A The partially enlarged view of the flip cover assembly 100 is used to more clearly illustrate the matching relationship between the driving device 140, the rocker arm 130 and the locking device 120. Figure 7 The flip cover assembly 100 is relative to Figure 1A The flip cover assembly 100 in the figure is rotated in a clockwise direction by a certain angle to show the right front side of the flip cover assembly 100. In order to conveniently show the driving shaft 643 of the driving device 140, Figure 7 The motor 150 is removed.

[0065] like Figure 7 As shown, one end of the drive shaft 643 of the drive device 140 that passes through the gear 641 is installed in the drive device installation hole 218 of the base 101. The gear 641 of the drive device 140 is located below the meshing portion 531 of the rocker arm 130. Figure 7 The motor 150 is not shown in the figure. Figures 1A-1C As can be seen from the illustrated content, the position of the motor 150 on the drive shaft 643 is located between the gear 641 and the eccentric device 642 of the drive device 140. The protrusion 646 of the eccentric device 642 can enter the receiving groove 435 of the eccentric device receiving portion 423 of the locking device 120.

[0066] The driving device 140 is configured to be able to rotate under the drive of the motor 150, so that the gear 641 and the eccentric device 642 can rotate with the rotation of the driving device 140. The gear 641 can drive the rocker arm 130 to rotate by engaging with the engaging portion 531 of the rocker arm 130 during the rotation process. During the rotation process of the eccentric device 642, the protrusion 646 of the eccentric device 642 can enter the receiving groove 435 of the eccentric device receiving portion 423 of the locking device 120, and can drive the locking device 120 to move by cooperating with the eccentric device receiving portion 425 of the locking device 120. In addition, the protrusion 646 of the eccentric device 642 can also be removed from the receiving groove 435 of the eccentric device receiving portion 423 of the locking device 120.

[0067] Specifically, during the rotation of the gear 641 of the driving device 140, when the toothed portion 652 of the gear 641 rotates to a position facing the meshing portion 531 of the rocker arm 130, the gear 641 meshes with the meshing portion 531 to drive the rocker arm 130 to rotate, thereby driving the flip cover 110 to open or close. When the smooth portion 654 of the gear 641 rotates to a position facing the meshing portion 531 of the rocker arm 130, the gear 641 does not mesh with the meshing portion 531, so that when the gear 541 rotates, the rocker arm 130 can remain stationary, and thus the flip cover 110 also remains stationary.

[0068] When the eccentric device 642 of the driving device 140 rotates in the direction of arrow J1, the protrusion 646 of the eccentric device 642 can enter the receiving groove 435 of the eccentric device receiving portion 423 of the locking rod 421 and reach the top of the receiving groove 435. Subsequently, as the eccentric device 1642 further rotates in the J1 direction, the protrusion 646 can apply a pulling force toward the proximal end of the base 101 to the locking rod 421 through the eccentric device receiving portion 423, thereby pulling the locking rod 421 toward the proximal end of the base 101, so that the locking rod 421 moves from the release position to the locking position. When the eccentric device 642 of the driving device 140 rotates in the opposite direction in the direction of arrow J2, the protrusion 646 of the eccentric device 642 can push the locking rod 421 to move toward the distal end of the base 101 so that the locking rod 421 can move from the locking position to the release position. When the locking rod 421 moves from the locking position to the releasing position, the smooth portion of the gear 641 faces the meshing portion 531 of the rocker arm 130 , so that the rocker arm 130 remains stationary, thereby making the flip cover 110 also remain stationary.

[0069] Since the flip cover 110 is opened and closed by the meshing of the meshing portion 531 of the rocker arm 130 and the gear 641, the angle at which the flip cover 110 is opened is the same as the angle at which the rocker arm 130 rotates when meshing with the gear 641. According to some embodiments, the central angle of the toothed portion 652 of the outer circumference of the gear 641 is greater than the maximum angle at which the flip cover can be opened.

[0070] The extension distance (or arc length) of the smooth portion 654 of the gear 641 is related to the travel of the locking rod 421 from the locking position to the releasing position. The center angle of the smooth portion 654 of the outer circumference of the gear 641 should be set large enough so that the eccentric device 642 can push the locking rod 421 from the locking position to the releasing position.

[0073] like Fig. 8A As shown, the flip cover 110 is in the closed position, and the locking receiving portion 311 of the flip cover 110 is inserted into the locking opening 205 and the locking channel 215 of the base 101. The locking rod 421 of the locking device 120 is in the locked position, and the locking pin 428 of the locking device 120 is inserted into the locking hole 315 of the locking receiving portion 311 of the flip cover 110. At this time, the flip cover 110 cannot be opened because it is locked.

[0074] When the lock rod 421 of the locking device 120 is in the locking position, the protrusion 646 on the eccentric device 642 of the driving device 140 is inserted into the receiving groove 435 of the eccentric device receiving portion 423 of the locking device 120, and the protrusion 646 is located at the top of the receiving groove 435. The smooth portion 654 of the gear 641 of the driving device 140 is opposite to the meshing portion 531 of the rocker arm 130.

[0075] exist Figure 8B middle, Figure 8B - (a) is a three-dimensional view of the flip cover assembly 100 when the flip cover 110 is in a closed position and a released state; Figure 8B -(b) Figure 8B - (a) is a partial cross-sectional enlarged view of the flip cover assembly 100 at the dotted line frame 830, which is used to show that the locking pin 428 of the locking rod 421 is outwardly withdrawn from the locking hole 315 of the flip cover 110; Figure 8B -(c) Figure 8B - (a) is a partial enlarged view of the flip cover assembly 100 at the dotted line frame 840, which is used to show the matching relationship between the gear 641 and the eccentric device 642 of the driving device 140, the meshing portion 531 of the rocker arm 130, and the eccentric device receiving portion 423 of the locking device 120, wherein for the sake of clarity of the diagram, Figure 8B - (c) The motor 150 is removed, and the flip cover assembly 100 is rotated a certain angle in the clockwise direction.

[0076] from FIG. 8A to FIG. 8BThe process of FIG. 1 shows the release process of the flip cover. In this process, the motor 150 drives the drive shaft 643 of the drive device 140 to rotate forward in the direction of the arrow J2, thereby driving the gear 641 and the eccentric device 642 to rotate forward in the direction of the arrow J2, and the protrusion 646 of the eccentric device 642 moves downward relative to the receiving groove 435, and applies a thrust to the lock rod 421 through the side wall 431 of the receiving groove 435, thereby pushing the lock rod 421 to move toward the far end of the base 101. As a result, the lock pin 428 gradually exits the lock hole 315 of the flip cover 110 outward with the movement of the lock rod 421 to release the flip cover 110. In this process, the smooth portion 654 of the gear 641 is opposite to the meshing portion 531 of the rocker arm 130, and the rotation of the gear 641 does not drive the rocker arm 130 to rotate, and the rocker arm 130 remains stationary.

[0077] exist Figure 8C middle, Figure 8C - (a) is a perspective view of the flip cover assembly 100 when the flip cover 110 is in a partially opened position; Figure 8C -(b) Figure 8C - (a) is a partial cross-sectional enlarged view of the flip cover assembly 100 at the position of the dotted line frame 850, which is used to show that the locking receiving portion 311 of the flip cover 110 gradually exits the locking opening 205 of the base 101; Figure 8C -(c) Figure 8C - (a) is a partial enlarged view of the flip cover assembly 100 at the dotted line frame 860, which is used to show the matching relationship between the gear 641 and the eccentric device 642 of the driving device 140, the meshing portion 531 of the rocker arm 130, and the eccentric device receiving portion 423 of the locking device 120, wherein for the sake of clarity of the diagram, Figure 8C - (c) The motor 150 is removed, and the flip cover assembly 100 is rotated a certain angle in the clockwise direction.

[0078] like Figure 8C As shown, after the lock pin 428 of the lock rod 421 has been withdrawn from the lock hole 315 of the flip cover 110 and the flip cover 110 is released, the motor 150 continues to drive the drive shaft 643 of the drive device 140 to rotate forward in the direction of the arrow J2. The gear 641 continues to rotate accordingly, and the toothed portion 652 of the gear 641 rotates to a position directly opposite to the meshing portion 531 of the rocker arm 130 and meshes with the meshing portion 531, so that the gear 641 drives the rocker arm 130 to rotate in the opposite direction, thereby driving the flip cover 110 to rotate and open. The eccentric device 642 also continues to rotate accordingly, and during the rotation process, the protrusion 646 of the eccentric device 642 will continue to move downward relative to the receiving groove 435 and gradually rotate out of the receiving groove 435.

[0079] exist Fig.8D middle, Fig.8D- (a) is a perspective view of the flip cover assembly 100 when the flip cover 110 is in a fully opened position; Fig.8D -(b) Fig.8D - (a) is a partial cross-sectional enlarged view of the flip cover assembly 100 at the dotted line frame 870, which is used to show that the locking pin 428 of the locking rod 421 is inserted into the locking channel 215 of the base 101; Fig.8D -(C) Fig.8D - (a) is a partial enlarged view of the flip cover assembly 100 at the dotted line frame 880, which is used to show the matching relationship between the gear 641 and the eccentric device 642 of the driving device 140, the meshing portion 531 of the rocker arm 130, and the eccentric device receiving portion 423 of the locking device 120, wherein for the sake of clarity of the diagram, Fig.8D - In (b), the motor 150 is removed, and the flip cover assembly 100 is rotated a certain angle in the clockwise direction.

[0080] like Fig.8D As shown, Figure 8C As shown, the motor 150 continues to drive the drive shaft 643 of the drive device 140 to rotate forward in the direction of arrow J2. The gear 641 remains meshed with the meshing portion 531 of the rocker arm 130 and continues to rotate until the flip cover 110 is fully opened. The eccentric device 642 also rotates accordingly and after rotating to a certain angle, the protrusion 646 of the eccentric device 642 rotates out of the receiving groove 435 and disengages from the locking rod 421, so that the spring 425 pushes the locking rod 421 toward the proximal end of the base 101 and returns to the locking position of the locking rod 421, so that the locking pin 428 of the locking rod 421 enters the locking channel 215 of the base 101. At this time, although the locking rod 421 of the locking device 120 is in a locked state, the locking device 120 cannot lock the flip cover 110 because the flip cover 110 is not closed.

[0081] Figures 9A-9D The process of closing and locking the flip cover 110 is shown, wherein Fig.9A A view showing the flip cover assembly 100 when the flip cover 110 is in a fully open position, Fig. 9B FIG. 1 shows a view of the flip cover assembly 100 when the flip cover 110 is in the process of closing. Fig. 9C A view showing the flip cover assembly 100 when the flip cover 110 is fully closed but not locked, Fig.9D A view of the flip cover assembly 100 is shown with the flip cover 110 closed and locked.

[0082] Fig.9A Corresponds to Fig.8D , which will not be elaborated here. Fig.9A The flip cover 110 is shown in a fully open position. If the flip cover 110 is to be closed, the motor 150 needs to drive the drive shaft 643 of the drive device 140 to reverse along the direction of the arrow J1.

[0083] exist Fig. 9B middle, Fig. 9B - (a) is a three-dimensional view of the flip cover assembly 100 when the flip cover 110 is in the process of closing; Fig. 9B -(b) Fig. 9B - (a) is a partial cross-sectional enlarged view of the flip cover assembly 100 at the dotted line frame 930, which is used to show that the locking pin 428 of the locking rod 421 is inserted into the through hole 207 of the base 101, but the locking pin 428 has not yet been inserted into the locking hole 315 of the flip cover 110; Fig. 9B -(c) Fig. 9B - (a) is a partial enlarged view of the flip cover assembly 100 at the dotted line frame 940, which is used to show the matching relationship between the gear 641 and the eccentric device 642 of the driving device 140, the meshing portion 531 of the rocker arm 130, and the eccentric device receiving portion 423 of the locking device 120, wherein for the sake of clarity of the diagram, Fig. 9B - In (C), the motor 150 is removed, and the flip cover assembly 100 is rotated a certain angle in the clockwise direction.

[0084] like Fig. 9B As shown, Fig.9A Compared with the above, the motor 150 drives the drive shaft 643 of the drive device 140 to reverse in the direction of arrow J1. The eccentric device 642 rotates accordingly. Since the lock rod 421 is in its locking position at this time, after the eccentric device 642 rotates to a certain angle, the protrusion 646 of the eccentric device 642 can enter the receiving groove 435 of the eccentric device receiving portion 423, so that the continued rotation of the eccentric device 642 can push the lock rod 421 to move toward the far end of the base 101 to its release position. The movement of the lock rod 421 from its locking position to its release position allows the lock pin 428 of the lock rod 421 to gradually withdraw from the locking channel 215 of the base 101, so that the lock receiving portion 311 of the flip cover 110 can be inserted into the locking channel 215 of the base 101. In this process, the gear 641 meshes with the meshing portion 531 of the rocker arm 130, driving the flip cover 110 to rotate from the fully open position to the closed position.

[0085] exist Fig. 9C middle, Fig. 9C - (a) is a perspective view of the flip cover assembly 100 when the flip cover 110 is completely closed but not locked; Fig. 9C -(b) Fig. 9C - (a) is a partial cross-sectional enlarged view of the flip cover assembly 100 at the position of the dotted line frame 950, which is used to show that the locking receiving portion 311 of the flip cover 110 is inserted into the locking channel 215 of the base 101, but the locking pin 428 of the locking device 120 has not yet been inserted into the locking hole 315 on the locking receiving portion 311 of the flip cover 110; Fig. 9C -(c) Fig. 9C - (a) is a partial enlarged view of the flip cover assembly 100 at the dotted line frame 960, which is used to show the matching relationship between the gear 641 and the eccentric device 642 of the driving device 140, the meshing portion 531 of the rocker arm 130, and the eccentric device receiving portion 423 of the locking device 120, wherein for the sake of clarity of the diagram, Fig. 9B - In (C), the motor 150 is removed, and the flip cover assembly 100 is rotated a certain angle in the clockwise direction.

[0086] like Fig. 9C As shown, when the flip cover 110 is completely closed but not locked, the eccentric device 642 holds the lock rod 421 in its release position through the eccentric device receiving portion 423, so that the lock pin 428 of the locking device 120 has not yet been inserted into the lock hole 315 on the lock receiving portion 311 of the flip cover 110. At this time, although the lock receiving portion 311 of the flip cover 110 is inserted into the lock channel 215 of the base 101, the flip cover 110 is not locked.

[0087] Fig.9D Corresponds to Fig. 8A , Fig.9D The description of each view in is not repeated here. FIG. 9C to FIG. 9D The process is the locking process of the flip cover 110. During this process, the motor 150 continues to drive the driving shaft 643 of the driving device 140 to reverse in the direction of the arrow J1. The eccentric device 642 continues to rotate accordingly. As the eccentric device 642 rotates, the protrusion 646 of the eccentric device 642 pulls the locking rod 421 from the release position to the locking position, so that the locking pin 428 is inserted into the locking hole 315 of the locking receiving portion 311 of the flip cover 110, thereby locking the flip cover 110. During the locking process of the flip cover 110, the smooth portion 654 of the gear 641 is opposite to the meshing portion 531 of the rocker arm 130, and the rotation of the gear 641 does not drive the rocker arm 130 to rotate, and the rocker arm 130 remains stationary.

[0088] In the existing flip cover assembly, the flip cover is usually opened and closed, and locked and unlocked in the following two ways. One way is: the opening and closing actions are manually operated, and the locking and releasing actions are automatically operated. For example, when the flip cover is in the closed position, the drive motor is first controlled to drive the locking device to release the flip cover, and then the flip cover is manually pressed, and the flip cover is bounced open by the cooperation of the push-push mechanism and the spring; when closing the flip cover, the flip cover is first manually closed to the closed position, and then the drive motor is controlled to drive the locking device to lock the flip cover. This operation requires manual operation from the outside of the vehicle body, and the opening and closing of the flip cover cannot be controlled inside the vehicle body. Another way is: both the switching action and the locking action are automatically operated, and are driven by their respective drive devices. This operation requires two sets of drive devices and their control interfaces, requires a large assembly space, and the installation and control are relatively complicated.

[0089] The flip cover assembly 100 and the flip cover actuation structure provided by the present application can automatically realize the opening and closing operation and the locking and unlocking operation of the flip cover 110 by using a power source (motor) 150, without the need for additional manual operation or operation outside the vehicle body. Therefore, the flip cover assembly 100 and the flip cover actuation structure provided by the present application require a small assembly space, and the control logic is also relatively simple. The switch action and the locking action that need to be coordinated with each other can be controlled through a set of control ports, which is not only convenient for assembly and operation, but also greatly improves the stability of operation.

[0090] This specification uses examples to disclose the present application, one or more of which are illustrated in the accompanying drawings. Each example is provided for the purpose of explaining the present application, not for limiting the present application. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the present application without departing from the scope or spirit of the present application. For example, features illustrated or described as part of one embodiment may be used together with another embodiment to obtain a further embodiment. Therefore, it is intended that the present application encompasses modifications and variations made within the scope of the appended claims and their equivalents.
