The application provides a battery tray for loading cylindrical battery shell 1, includes: a base 10 for holding the housing 1; a first sidewall 20, an inner surface of the first sidewall 20 having at least one first groove 21 and at least one first boss 22, the first groove 21 alternating with the first boss 22; a second sidewall 30 disposed opposite to the first sidewall 20, an inner surface of the second sidewall 30 having at least one second groove 31 and at least one second projection 32, the second groove 31 alternating with the second projection 32; wherein any first recess 21 is opposite to one second boss 32 and/or any second recess 31 is opposite to one first boss 22.

The battery tray further includes: a third sidewall 40 connecting the first sidewall 20 and the second sidewall 30; and a fourth sidewall 50 disposed opposite the third sidewall 40 and connecting the first sidewall 20 and the second sidewall 30.

It is easy to understand that the first side wall 20, the second side wall 30, the third side wall 40 and the fourth side wall 50 are all disposed on the base 10 and are connected with each other to form a cavity with an upper end opened for receiving the housing 1.

Wherein the inner surface of the first sidewall 20 provided with the first groove 21 and the first boss 22 is disposed in the first direction. For convenience of description of the housing 1 loaded in the battery tray, the first direction is defined as a row direction; in short, when the inner surface of the first sidewall 20 has a first grooves 21 and b first bosses 22 along the first direction, the tray can load a + b rows of shells.

The inner surface of the second side wall 30 provided with the second groove 31 and the second boss 32 can also be provided in the first direction. At this time, when the groove depths of the first groove 21 and the second groove 31 are the same, the heights of the first boss 22 and the second boss 32 are the same, or the distance between the first groove 21 and the second boss 32 is the same as the distance between the second groove 31 and the first boss 22, the same number of cases 1 can be loaded in any one row of the tray.

Alternatively, the inner surface of the second side wall 30 can be arranged in other directions than the first direction, in which case the distance between the first recess 21 and the second boss 32, and the distance between the second recess 31 and the first boss 22 in any one row are different, so that a different number of housings 1 can be loaded in any one row of the tray.

In addition, when the extending direction of the inner surface of the first sidewall 20 is different from the extending direction of the inner surface of the second sidewall 30, the projection length of the inner surface of the second sidewall 30 in the first direction may be the same as or different from the projection length of the inner surface of the first sidewall 20 in the first direction. When the projection lengths of the two are different, one side wall with longer projection length can be used for placing more rows of shells 1; however, since the other opposite sidewall lacks the groove and the boss which are matched with the other opposite sidewall in the first direction, the groove and the boss are correspondingly arranged on the third sidewall 40 and/or the fourth sidewall 50, and the first sidewall 20 or the second sidewall 30 with a longer projection length is matched to realize the loading of more rows of the shells 1.

The third and fourth sidewalls 40 and 50 are arranged in a similar manner to the first and second sidewalls 20 and 30. Details are not repeated.

Wherein the inner surface of the third sidewall 40 is disposed in the second direction, which intersects the first direction since the third sidewall 40 connects the first sidewall 20 and the second sidewall 30.

When the inner surfaces of the third sidewall 40 and the fourth sidewall 50 are relatively parallel, the inner surface of the fourth sidewall 50 is also arranged along the second direction, and at this time, the projection length of the inner surface of the second sidewall 30 in the first direction is the same as the projection length of the inner surface of the first sidewall 20 in the first direction, and the first sidewall 20 and the second sidewall 30 are matched with the boss (the first boss 22 or the second boss 32) through the groove (the first groove 21 or the second groove 31), so that the loading of the multi-row housing 1 is realized.

It should also be explained that, in the battery tray, any one row of the housings 1 may be arranged in the arrangement direction of the inner surfaces of the third side walls 40, or the arrangement direction of the inner surfaces of the fourth side walls 50. Alternatively, any row of the housings 1 may be arranged in other directions different from the arrangement direction of the inner surfaces of the third and fourth sidewalls 40 and 50. However, it is easily understood that arranging at least two housings in a row along the arrangement direction of the inner surfaces of the third and fourth sidewalls 40 and 50 enables better use of the space within the tray, thereby loading more housings 1 within the tray.

In one embodiment, referring to fig. 1, the inner surfaces of the first and second sidewalls 20 and 30 are disposed in a first direction, and the inner surfaces of the third and fourth sidewalls 40 and 50 are disposed in a second direction, which is horizontally perpendicular to the first direction, so that the battery tray is used to place the cavity of the housing 1, and the projection of the battery tray in the horizontal plane is substantially rectangular.

Specifically, in the embodiment shown in fig. 1, the battery tray can be loaded with two rows of the housings 1, each row including five housings 1 arranged in the second direction.

Since fig. 1 to 5 and fig. 9 are schematic views of battery trays of different models from the same perspective, and the first direction is the up-down direction, and the second direction has a component of the left-right direction, for the convenience of the following description of the tray inner and outer shells 1, the first row of outer shells 1 disposed above is defined as the first row of outer shells 1, the next row of outer shells 1 adjacent to the first row of outer shells is the second row of outer shells 1 … …, and so on, the lowermost row of outer shells 1 is the last row of outer shells 1. Meanwhile, the first housing 1 disposed on the left is defined as the first housing 1 in each row, the right housing 1 adjacent thereto is the second housing 1 … … in the row, and so on, and the housing 1 disposed on the rightmost side in each row is the last housing 1 in the row.

Thus, in fig. 1, a first row of first housings 1 is arranged in the first recess 21 and a last housing 1 is arranged on the second projection 32; the first shell 1 of the second row is arranged on the first boss 22 and the last shell 1 is arranged in the second recess 31. Because the lug bosses are protruded in the cavity body compared with the grooves, the positions of the two rows of shells 1 are staggered; for example, the center of the circle of the first housing 1 of the second row is located between the centers of the circles of the first and second housings 1 of the first row.

In another embodiment, referring to fig. 2, the inner surfaces of the first and second side walls 20 and 30 are disposed in a first direction, and the inner surfaces of the third and fourth side walls 40 and 50 are disposed in a second direction, which is disposed at an acute angle to the first direction, so that the battery tray is used to place the cavity of the housing 1, and its projection in the horizontal plane is substantially parallelogram.

For convenience of description, the x-th housing 1 of any two adjacent rows of housings 1 is referred to as a corresponding housing. Therefore, by arranging the groove and the lug boss, the connecting line of the circle centers of the circular projections of any two corresponding shells is intersected with the first direction. At this time, any adjacent two rows of housings 1 are arranged in a staggered manner.

In other embodiments, the inner surfaces of the first and second sidewalls 20 and 30 are disposed along a first direction, the inner surface of the third sidewall 40 is disposed along a second direction, and the inner surface of the fourth sidewall 50 is disposed along a third direction, which intersects the first direction and is different from the second direction, so that the battery tray is used for placing the cavity of the housing 1, and the projection of the battery tray in the horizontal plane is substantially trapezoidal.

In another embodiment, the inner surface of the first sidewall 20 is disposed along the first direction, the inner surface of the second sidewall 30 is disposed along the fourth direction, the inner surface of the third sidewall 40 is disposed along the second direction, and the inner surface of the fourth sidewall 50 is disposed along the third direction, wherein the first direction, the second direction, the third direction, and the fourth direction intersect with each other and are different from each other, so that the battery tray is used for placing the cavity of the housing 1, and the projection of the battery tray in the horizontal plane is substantially in the shape of a trapezoid.

The present application does not limit the configuration of the battery tray. As long as through at least two relative lateral walls, set up recess and the boss of mutually supporting, can realize the dislocation of shell 1 and arrange.

Specifically, when at least two rows of the housings 1 are arranged in a staggered manner, a first housing 1 of one row is arranged in the first groove 21, and a last housing 1 is arranged on the second boss 32 in any two adjacent rows of the housings 1; the first housing 1 of the other row is arranged on the first boss 22 and the last housing 1 is arranged in the second recess 31. Because the first boss 22 is used for contacting the table top of the housing 1, protrudes from the first groove 21 along the second direction and is used for contacting the groove bottom of the housing 1, the center of a circle of the circular projection of the housing 1 placed in the first groove 21 is positioned on the left side of the center of a circle of the circular projection of another housing 1 placed on the first boss 22, and because a plurality of housings 1 in a row are arranged in sequence, the position of the center of a circle of the first housing 1 determines the positions of other housings 1, so that the two rows of housings 1 are staggered with each other.

When two adjacent rows of shells 1 are arranged in a staggered manner, the two rows of shells 1 can occupy a space adjacent to the shell 1 in the other row.

The "misalignment arrangement" is explained in detail by taking fig. 3 as an example.

In the embodiment shown in fig. 3, nine staggered rows of housings 1 are provided, and each row comprises five housings 1.

Among any two rows of adjacent shells 1, the distance between the projections of the circle centers of the x-th shell 1 in one row and the x-th shell 1 in the other row (namely, two corresponding shells) in a plane parallel to the first direction is smaller than the sum of the radii of the two circles.

It should be noted that, since the main body of the housing 1 is substantially cylindrical, when the housing 1 is vertically placed, its projection in the horizontal plane is circular, as shown in fig. 1 to 5 and 9. When the battery tray provided by the application is used for loading the shells 1, each shell 1 is vertically placed on the base 10. Therefore, the "circular projection" represents a state when the housing 1 is loaded in the tray.

In order to house as many housings 1 as possible, a plurality of housings 1 in any one row are adjacent to each other or even in contact. Due to the characteristics of the arc, the distance between the two adjacent housings 1 gradually increases from the position where the two housings 1 are close to each other.

It should be added that two adjacent housings 1 in any row may abut against each other, or may have a certain gap. Due to the characteristics of the circular arc, a space with the caliber gradually reduced from outside to inside is formed between the two shells 1. For convenience of the following description, this space is referred to as a bit avoidance space.

For example, in the embodiment shown in fig. 3, the right side of a first housing 1 in a first row abuts against the left side of a second housing 1, and the circular projections of the two housings 1 are tangential. The distance between the outer walls of the two shells 1 gradually increases from the tangent point to the top or the bottom of the shell 1, and the distance between the two shells 1 is the sum of the radii of the two circular projections.

Referring to fig. 7, when the plurality of rows of housings 1 are arranged in an array, the centers of the circular projections of the x-th housing 1 in any row are on the same straight line. At this time, in any two rows of adjacent shells 1, the space for avoiding the position adjacently formed by the x-th shell 1 and the x + 1-th shell 1 in one row is opposite to the space for avoiding the position adjacently formed by the x-th shell 1 and the x + 1-th shell 1 in the other row, so that a larger space for avoiding the position is formed. Therefore, when the shell 1 is arranged in the array, more avoiding spaces exist in the jig and cannot be used, so that the space utilization rate of the jig is low.

By arranging at least two rows of shells 1 in a staggered manner, the space avoiding space formed by the x-th shell 1 adjacent to the x + 1-th shell 1 in one row can be at least partially occupied by the x-th shell 1 in the other row.

With continued reference to fig. 3, the top of the first housing 1 of the second row is in the space of the first and second housings 1. As can be seen, the bottom of the shells 1 in the first row can occupy the space of avoidance partly formed by the shells 1 in the second row, while the top of the shells 1 in the second row can occupy the space of avoidance partly formed by the shells 1 in the first row. The space is avoided through effective utilization, the utilization ratio of the accommodating space in the battery tray can be improved, and therefore more shells 1 can be placed in the limited space, or the shells 1 with the same quantity can be placed in the less space.

In addition, when the at least two rows of the housings 1 are arranged in a staggered manner, at least a part of the housing 1 in the space can be influenced by the two housings 1 in the other row forming the space, thereby defining the position of the housing 1 on the base 10.

For example, referring to FIG. 3, the first shell 1 of the second row is shown_2-1Which isFirst and second housings 1 having top portions in a first row_1-1And 1_1-2Formed in a space of clearance with its bottom part in the first and second housings 1 of the third row_3-1And 1_3-2In the formed avoiding space. Thus, the housing 1_2-1Is received by the housing 1 in the up-down direction_1-1And 1_1-2And a housing 1_3-1And 1_3-2While the left-right direction is restricted by the boss and the adjacent second housing 1_2-2Thereby, the housing 1_2-1The position on the base 10 is stable and is not easy to topple or displace.

In summary, when at least two rows of shells 1 are arranged in a staggered manner, any shell 1 in the battery tray is not only constrained by the adjacent shell 1 in the same row, but also constrained by the shell 1 in the other adjacent row, and the shells 1 in the rows interact with each other, so that the stable loading of the shells 1 in the battery tray is ensured, the shells are prevented from toppling or shifting, and the position of the shells 1 in the loading process can be conveniently confirmed, so that the shells 1 can be conveniently loaded.

In one embodiment, in the first direction, the first sidewall 20 is provided with N first grooves 21 and N-1 first bosses 22; in the first direction, the second sidewall 30 is provided with N-1 second grooves 31 and N-2 second bosses 32. At this time, any one of the second grooves 31 is opposed to one of the first bosses 22.

To ensure the staggered arrangement of the housings 1, due to the absence of two second projections 32 compared to the first recesses 21, in one embodiment, a third recess 33 may be provided on the second side wall 30 opposite the first recess 21 and/or the last first recess 21 in the first direction, and referring to fig. 4, the third recess 33 is closer to the outer wall of the second side wall 30 than the second recess 31, so that the housings 1 in the first row and/or the last row are arranged one more than the housings 1 in the other rows.

It should be added that the application does not limit the number of shells 1 in any row. The number of shells 1 in a row can be adjusted by providing grooves of different groove depths and/or bosses of different heights. The present application enables a staggered arrangement of at least parts of the housing 1 by providing the opposing first recess 21 and second boss 32, and the second recess 31 and first boss 22. When the shell 1 is arranged in a staggered mode, the accommodating space in the battery tray can be effectively utilized.

In another embodiment, referring to fig. 3, the first sidewall 20 is provided with N first grooves 21 and N-1 first bosses 22; the second side wall 30 is provided with N-1 second grooves 31 and N second bosses 32. At this time, any one of the first grooves 21 is opposed to one of the second bosses 32, and at the same time, any one of the second grooves 31 is opposed to one of the first bosses 22.

Further, the groove bottom of the first groove 21 and/or the second groove 31 is a plane. At this time, when the first or last housing 1 in a row abuts against the groove, the housing 1 is in line contact with the groove bottom of the groove because the shell surface of the housing 1 is a circular arc surface. At this time, the circular projection of the housing 1 is tangent to the bottom of the straight line groove of the groove. From the tangent point outwards, the recess is kept away from gradually to the outer wall of shell 1 for have the clearance between recess and the shell 1, conveniently take out shell 1.

It should be added that the housing 1 in the groove does not necessarily abut against the groove bottom of the groove, and the housing 1 may have a certain clearance with the groove bottom, but outward from the position of the housing 1 closest to the groove bottom, the outer wall of the housing 1 still gets farther and farther away from the groove, and the effect of facilitating the removal of the housing 1 is the same.

Of course, in other embodiments, the groove bottom of the first groove 21 and/or the second groove 31 may also be a cambered surface. So, when shell 1 leaned on the recess, the cambered surface can laminate partial shell 1 to accept shell 1 better, play the positioning action to shell 1.

Similarly, the inner surface of the third sidewall 40 and/or the fourth sidewall 50 may also be provided with a plurality of arc-shaped grooves 41, so that the shells 1 of the first row and/or the last row can fit the arc-shaped grooves 41. The arc-shaped groove 41 can further position the shell 1, and can also facilitate the confirmation of the placing position of the shell 1 in the loading process, so that the shell 1 can be conveniently loaded.

Referring to fig. 5, the first row of the first housing 1_1-1When loading, the shell 1_1-1Fits a first arc on the third side wall 40A groove 41, and the housing 1_1-1The left side portion of which abuts the first recess 21; the first arcuate recesses 41 and the first recesses 21 cooperate to define a space into which the housings 1 are inserted, and any one of the housings 1 serves as a first row of first housings 1_1-1When loading, all will be restricted by first arc recess 41 and first recess 21. When the first housing 1_1-1After the second shell 1 is accurately positioned, the second shell 1 is continuously fed_1-2And make the housing 1_1-2Abuts against the second arc-shaped recess 41 of the third side wall 40, and the housing 1_1-2Abuts against the first housing 1_1-1Thus, any one of the housings 1 serves as the second housing 1 of the first row_1-2When loading, the material is loaded by the second arc-shaped groove 41 and the first shell 1_1-1Limiting … … and so on, after finishing the arrangement of all the shells 1 in the first row one by one, feeding the first shell 1 in the second row_2-1So that the housing 1_2-1Is limited to a first housing 1_1-1And a second housing 1_1-2In a space of avoidance formed by the mutual contact, and the shell 1_2-1Against the first boss 21, any one of the housings 1 as the second row of the first housing 1_2-1During the material loading, all can be by the spacing space of keeping away of top and the left first boss 21 restriction … … and so on, accomplish the material loading of shell 1, can guarantee that the shell in the battery tray all is in corresponding preset position, makes things convenient for downstream processing.

Of course, the inner surfaces of the third and fourth sidewalls 40 and 50 may also be planar. In the embodiment shown in fig. 3, the top of the first row of housings 1 can abut against the third side wall 40 and the bottom of the last row of housings can abut against the fourth side wall 50. Due to the characteristics of the arc, the distance between the outer wall of the housing 1 and the third sidewall 40 or the fourth sidewall 50 is larger and larger from the tangent point of the circular projection of the housing 1 and the third sidewall 40 or the fourth sidewall 50 to leave a gap and facilitate the taking out of the housing 1.

Further, from the notch of the first groove 21 to the bottom of the first groove 21, the opening of the first groove 21 is gradually reduced; and/or the opening of the second groove 31 is gradually reduced from the notch of the second groove 31 to the groove bottom of the second groove 31.

In this case, the first recess 21 or the second recess 31 is similar to a trumpet-shaped recess, the larger opening facilitates the entrance and exit of the housing 1, the increasingly closer groove walls from the outside to the inside can guide the housing 1 into the groove bottom, and the smaller groove bottom can limit the final position of the housing 1.

Wherein, the groove wall of the first groove 21 and/or the second groove 31 may be a cambered surface. By arranging the groove wall of the groove as an arc surface, the situation that the insertion or extraction of the housing 1 is hindered when the connecting position of the groove and the third side wall 40 and/or the fourth side wall 50 is a right angle can be avoided.

Further, the tops of the first bosses 22 and/or the second bosses 32 are cambered surfaces.

In an embodiment, the arc surface of the top of the first boss 22 and/or the second boss 32 is recessed so as to fit the housing 1, thereby limiting the insertion position of the housing 1.

In another embodiment, the arc surface of the table top of the first boss 22 and/or the second boss 32 is protruded, so as to reduce the contact area between the table top and the housing 1, and release more arc surface space while abutting against the housing 1 and limiting the position of the housing 1 to be placed, thereby facilitating the removal of the housing 1.

As can be seen from the above, the battery tray can carry at least two rows of housings 1 in the first direction, optionally, any row includes a plurality of housings 1 arranged in the second direction. In order to occupy more space for avoiding space and further improve the utilization rate of the accommodating space in the battery tray, the circle center of the circular projection of the x-th shell 1 in one row is opposite to the tangent point of the projection of the x-th and x + 1-th shells 1 in the other row in the horizontal plane in any two adjacent rows of shells 1.

It will be readily appreciated that under normal use, a batch of shells 1, which are tray-loaded, are very close to, or even identical in size. In this case, the radii of the circular projections of the housings 1 may be considered to be uniform. It can be seen that when the circular projections of the two shells 1 are tangent, the space between the two shells gradually decreases from outside to inside. Therefore, in the multi-row shells arranged in a staggered manner, one part of the shell 1 in the (n + 1) th row is positioned in the avoiding space formed by two butted shells 1 in the (n) th row, so that the circle center of the circular projection of the shell 1 in the (n + 1) th row is opposite to the tangent point of the circular projections of the two shells 1 in the (n) th row, and the shell 1 can be deeply inserted into the avoiding space to the greatest extent.

Meanwhile, in the (n + 1) th row, the circle center of the circular projection of the next shell 1 adjacent to the shell 1 is still opposite to the tangent point of the circular projections of the two shells 1 in the (n) th row … …, and so on, and in the (n + 1) th row, any shell 1 occupying the space to avoid can go deep into the space to avoid to the greatest extent.

As will be readily appreciated, the housings 1 in the (n + 1) th row occupy the space to the greatest extent when the circular projection of the x-th housing 1 in the (n + 1) th row is simultaneously tangential to the circular projections of the x-th and x + 1-th housings 1 in the (n + 1) th row.

Further, the first sidewall 20, the second sidewall 30, the third sidewall 40, and/or the fourth sidewall 50 are a double-layer structure. When the battery tray is carried or extracted, the manual work or the mechanical work is more directly acted on the side wall of the tray; at the same time, part of the housing 1 in the battery tray is close to, or even in direct contact with, the side walls of the tray.

In order to avoid the deformation of the side wall caused by the external force acting on the side wall of the tray, the shell 1 in the tray is influenced, and the side wall of the tray needs to be reinforced. By providing the first, second, third and/or fourth sidewalls 20, 30, 40 and/or 50 as a double-layered structure, it is possible to improve stability of the sidewalls by increasing the thickness of the sidewalls.

In one embodiment, the base 10, the first sidewall 20, the second sidewall 30, the third sidewall 40, and/or the fourth sidewall 50 of the tray may be made of a plastic material. Referring to fig. 6, when the side wall is set to be a double-layer structure, the side wall can be turned over, so that the height of the side wall is reduced, and the side wall is thickened.

In other embodiments, the double-layer structure of the side wall can be realized by overlapping different materials. For example, the inner layer of the side wall close to the housing 1 is made of a non-metallic material so as to avoid the side wall damaging the housing or affecting the battery cell, but the outer layer of the side wall may be made of a metallic material so as to improve the rigidity of the side wall.

It is easy to think that the base 10 can also be provided with a double-layer structure, similar to the side wall, and the description is omitted.

Further, the first sidewall 20 is connected to the third sidewall 40 through the first arc surface 3, the first sidewall 20 is connected to the fourth sidewall 50 through the second arc surface 4, the second sidewall 30 is connected to the third sidewall 40 through the third arc surface 5, and/or the second sidewall 30 is connected to the fourth sidewall 50 through the fourth arc surface 6.

Referring to fig. 1, through setting up first cambered surface 3, second cambered surface 4, third cambered surface 5 or fourth cambered surface 6, can reduce the danger of tray corner, avoid the corner of tray because sharp injury operating personnel or draw damage mechanical equipment.

Further, a card slot 11 for placing the housing 1 is arranged on the base 10. The card slot 11 is recessed inward with a certain depth. When casing 1 was arranged in draw-in groove 11, draw-in groove 1's lateral wall can act on casing 1, can enough inject casing 1's position, can fix casing 1 again, and casing 1 displacement in tray 1 when avoiding the tray to remove.

Further, the bottom of the card slot 11 is provided with a receiving slot 12 for placing the protrusion 2 at the bottom of the housing 1.

It should be explained that the battery also has an electrode for current flow, which usually protrudes from the battery cell and is embodied on the housing 1, and that, with reference to fig. 8, the housing 1 also has a protrusion 2 on the bottom.

If the accommodating groove 12 is not formed in the bottom of the clamping groove 11, when the bottom of the shell 1 is placed in the clamping groove 11, the protrusion 2 contacts the bottom of the clamping groove 11, and finally the whole shell 1 is supported through the protrusion 2. However, it is easily understood that since the protrusion 2 is small in size and has a certain height, the housing 1 is easily inclined or even fallen down while only the housing 1 is supported by the protrusion 2. Meanwhile, the projection 1 is easily deformed by the gravity of the entire housing 1.

For this reason, referring to fig. 9, a receiving groove 12 dedicated to receiving the protrusion 2 is provided, when the housing 1 is placed in the card slot 11, the protrusion 2 of the housing 1 is in the receiving groove 12, and the receiving groove 12 can receive the protrusion 2, so as to prevent the protrusion 2 from independently supporting the housing 1. Meanwhile, a portion of the bottom of the housing 1 without the projection 2 is at the bottom of the card slot 11 without the receiving slot 12, thereby supporting the housing 1 instead of the projection 2.

When the depth of accommodating groove 12 is greater than the height of protrusion 2, after housing 1 is placed in clamping groove 11, protrusion 2 is suspended in accommodating groove 12, and at this moment, protrusion 2 is no longer influenced by the gravity of housing 1, further avoiding protrusion 2 to deform.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
