Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Positioning fixtures, as core equipment for achieving precise positioning of shock absorbers and lower forks, ensure that shock absorbers and lower forks maintain accurate relative positions and postures during assembly, thereby effectively improving assembly accuracy and product quality.

[0036] However, positioning fixtures in related technologies are typically only compatible with specific types of shock absorbers. For example, a positioning fixture can only be used with air spring shock absorbers or coil spring shock absorbers, and cannot be compatible with both simultaneously. This limited compatibility of positioning fixtures necessitates the use of separate positioning fixtures for different types of shock absorbers, leading to higher vehicle production costs.

[0037] To address or improve the problem of limited adaptability of positioning fixtures, this utility model provides a positioning fixture and production line.

[0038] The following is combined Figures 1 to 7 This describes the positioning fixture provided in the embodiments of the present invention.

[0039] Specifically, the positioning fixture is used to assemble the shock absorber 4 and the lower fork arm 5, wherein the shock absorber 4 can be an air spring shock absorber or a coil spring shock absorber. The positioning fixture includes a support 1, a first positioning component 2, and a second positioning component 3.

[0040] Optionally, the support 1 includes a base 101 and a stand 102 connected to each other. For example, the base 101 may be a base plate, and the stand 102 may be a column. For example, the base plate and the column may be screwed or welded together.

[0041] The first positioning component 2 is disposed on the support 1 and is used to connect with the lower fork arm 5 to position the lower fork arm 5. For example, the first positioning component 2 is disposed on the base 101.

[0042] The second positioning component 3 is disposed on the support 1, for example, on the stand 102, and includes a first positioning member 301 and a second positioning member 302. The second positioning member 302 is used to connect with the connecting plate 402 of the shock absorber 4 to position the connecting plate 402 of the shock absorber 4. It is understood that the connecting plate 402 of the shock absorber 4 is also called the upper seat. Depending on the type of shock absorber 4, the connecting plate 402 can be used to connect with the body, shock absorber tower, frame or subframe, and the components it connects to are not limited here.

[0043] The first positioning element 301 is movably connected to the support 1. For example, the first positioning element 301 can be slidably connected or rotatably connected to the support 1, and the first positioning element 301 can switch between the working position and the clearance position.

[0044] In the working position, the first positioning member 301 is used to connect with the spring base 401 of the shock absorber 4. In the avoidance position, the first positioning member 301 is used to shift to one side of the shock absorber 4 to move away from the shock absorber 4.

[0045] It is understandable that only coil spring shock absorbers have spring base 401; please refer to [reference needed]. Figure 7 The diagram shows a helical spring shock absorber. The spring base 401 is typically connected to the outer wall of the shock absorber cylinder, and the connecting plate 402 is connected to the piston rod of the shock absorber cylinder. The helical spring is positioned between the connecting plate 402 and the spring base 401. Alternatively, the helical spring can directly abut against the connecting plate 402, or indirectly abut against the connecting plate 402 via a shock-absorbing pad or similar material.

[0046] In this embodiment, the positioning fixture can be used for assembling the helical spring shock absorber and the lower fork arm 5, and also for assembling the air spring shock absorber and the lower fork arm 5.

[0047] For example, when assembling the coil spring shock absorber with the lower fork arm 5, the lower fork arm 5 is connected to the first positioning component 2 so as to position the lower fork arm 5 through the first positioning component 2.

[0048] Additionally, the first positioning member 301 is switched to the working position, and the spring base 401 of the coil spring shock absorber is connected to the first positioning member 301 to position the spring base 401. The connecting plate 402 of the coil spring shock absorber is connected to the second positioning member 302 to position the connecting plate 402. Then, the coil spring shock absorber can be connected and fixed to the lower fork arm 5.

[0049] When assembling the air spring shock absorber with the lower fork arm 5, the lower fork arm 5 is connected to the first positioning component 2 so as to position the lower fork arm 5 through the first positioning component 2.

[0050] In addition, the first positioning member 301 is switched to the clearance position so that the first positioning member 301 is offset from one side of the air spring shock absorber. Since the air spring shock absorber does not have a spring base 401, this can avoid interference between the first positioning member 301 and the air spring shock absorber.

[0051] Connect the connecting plate 402 of the air spring shock absorber to the second positioning member 302 to position the connecting plate 402 via the second positioning member 302. Then the air spring shock absorber can be connected and fixed to the lower fork arm 5.

[0052] That is, the first positioning component 301 can move to the working position to cooperate with the spring base 401 of the coil spring shock absorber to achieve precise positioning, or it can move to the avoidance position to offset to the side of the shock absorber 4 to avoid interference with the air spring shock absorber without the spring base 401.

[0053] With this configuration, the first positioning component 2 and the second positioning component 3 work together to position the lower fork arm 5 and the shock absorber 4 separately. Simultaneously, the second positioning component 3 includes a second positioning element 302 and a movable first positioning element 301. By switching the first positioning element 301 between the working position and the clearance position, compatibility with both coil spring shock absorbers and air spring shock absorbers is achieved. This eliminates the need to develop separate tooling for air springs and coil spring shock absorbers, reducing production line equipment investment and maintenance costs.

[0054] In some embodiments provided by this utility model, a first guide structure 103 is provided on the support 1, for example, the first guide structure 103 is disposed on the upright 102 of the support 1. Correspondingly, the first positioning member 301 is slidably connected to the first guide structure 103, for example, the first guide structure 103 is configured as a guide rail, and the extension direction of the first guide structure 103 intersects with or is not in the same plane as the axis of the shock absorber 4.

[0055] In this embodiment, the first positioning member 301 can be switched between the working position and the avoidance position by sliding the first positioning member 301. Sliding the first positioning member 301 achieves the switching between the working position and the avoidance position without disassembling or replacing parts, thus improving operational efficiency. A first guide structure 103 is provided on the stand 102, which is not parallel to the axis of the shock absorber 4, ensuring that the sliding trajectory of the first positioning member 301 can avoid the air spring shock absorber 4.

[0056] Optionally, the sliding of the first positioning member 301 can be manually operated, or a reciprocating drive mechanism can be provided to drive the first positioning member 301 to slide. For example, the reciprocating drive mechanism includes, but is not limited to, a gear and rack drive mechanism, a lead screw and nut drive mechanism, a cylinder or a hydraulic cylinder.

[0057] Of course, the first positioning member 301 is not limited to a sliding connection with the support 1. For example, in other embodiments not shown, the first positioning member 301 can be rotatably connected to the support 1, with the axis of rotation of the first positioning member 301 offset from the axis of the shock absorber 4. For example, the axis of rotation of the first positioning member 301 can be parallel to the axis of the shock absorber 4, so that the first positioning member 301 can swing horizontally. In this way, the first positioning member 301 can switch between the working position and the clearance position by rotation.

[0058] In some embodiments provided by this utility model, the first positioning member 301 includes a first adjusting seat 3011, a first mounting seat 3012 and a first positioning post 3013.

[0059] The first adjusting seat 3011 is movably connected to the support 1. For example, the first adjusting seat 3011 is slidably connected to the first guide structure 103, or the first adjusting seat 3011 is rotatably connected to the support 1.

[0060] The first mounting base 3012 and the first adjusting base 3011 are detachably connected, for example, the first mounting base 3012 and the first adjusting base 3011 are screwed together.

[0061] The first positioning pin 3013 is disposed on the first mounting base 3012 and is used to limit the engagement with the first positioning hole 4011 of the spring base 401. For example, the first positioning pin 3013 is configured as a positioning pin or positioning shaft, and extends upward along the height direction of the positioning fixture. It is understood that the spring base 401 is usually provided with a first positioning hole 4011.

[0062] In this embodiment, when connecting the helical spring shock absorber 4 to the first positioning member 301, the first positioning hole 4011 of the spring base 401 is aligned with the first positioning post 3013, and then the helical spring shock absorber 4 is lowered so that the first positioning post 3013 passes into the first positioning hole 4011.

[0063] By mounting the first positioning pin 3013 onto the first mounting base 3012 and detachably connecting the first mounting base 3012 to the first adjusting base 3011, it is possible to replace the first mounting base 3012 with different sizes or shapes, thereby adjusting the position of the first positioning pin 3013. This allows the positioning fixture to be compatible with shock absorbers 4 with different positions of the first positioning hole 4011. Simultaneously, the connection between the first adjusting base 3011 and the support 1 does not need to be disconnected, thus reducing the difficulty of replacement.

[0064] Optionally, the first positioning post 3013 can be directly installed on the first mounting base 3012.

[0065] Of course, the first positioning post 3013 can also be indirectly mounted on the first mounting base 3012. For example, the first positioning component 301 also includes a first transition seat 3014, which is mounted on the first mounting base 3012, and the first positioning post 3013 is mounted on the first transition seat 3014. This arrangement makes it easy to ensure the positional accuracy of the first positioning post 3013 by adjusting the shape and relative position of the first mounting base 3012 and the first transition seat 3014.

[0066] Optionally, the first positioning post 3013 is detachably connected to the first mounting base 3012 to facilitate the replacement of the first positioning post 3013 with different diameters.

[0067] Optionally, the first adjusting seat 3011 and the first mounting seat 3012 are slidably fitted along the axial direction of the first positioning post 3013. For example, one of the first adjusting seat 3011 and the first mounting seat 3012 is provided with a groove 3011a, and the other is provided with a protrusion 3012a that is slidably connected to the groove 3011a. The extending direction of the groove 3011a is consistent with the axial direction of the first positioning post 3013. A through groove is provided at the bottom of the groove 3011a, which penetrates the first adjusting seat 3011 or the first mounting seat 3012 and extends along the length direction of the groove 3011a.

[0068] Furthermore, the first adjusting seat 3011 and the first mounting seat 3012 can be connected by a threaded connector, for example, the threaded connector passes through the slide groove 3011a and the through groove, and is connected to the first adjusting seat 3011 or the first mounting seat 3012.

[0069] For example, Figure 4 The illustration shows an example where the first adjusting seat 3011 has a groove 3011a and the first mounting seat 3012 has a protrusion 3012a; of course, the reverse is also possible. Accordingly, the threaded connector passes through the groove 3011a and the through groove of the first adjusting seat 3011 and is threadedly connected to the first mounting seat 3012; alternatively, the threaded connector passes through the first adjusting seat 3011 and the first mounting seat 3012 and is threadedly connected to the nut.

[0070] In this embodiment, the first adjusting seat 3011 is slidably connected to the first mounting seat 3012, so that the position of the first positioning post 3013 can be adjusted along the axis of the first positioning post 3013 to accurately match the axial deviation of the positioning holes of different spring bases 401.

[0071] In some embodiments provided by this utility model, the second positioning component 3 further includes a first locking mechanism 303. The first locking mechanism 303 is disposed on the first positioning member 301 or the support 1, and can selectively lock the first positioning member 301 to the first guide structure 103 or release it.

[0072] In this embodiment, the first locking mechanism 303 achieves operational stability and ease of adjustment for the first positioning component 301 through selective locking. For example, when positioning the helical spring shock absorber 4, the first locking mechanism 303 securely fixes the first positioning component 301 in the working position, ensuring accurate positioning. When assembling the air spring shock absorber 4, releasing the lock allows the first positioning component 301 to be switched to the clearance position, preventing interference and effectively improving the reliability of tooling positioning and ease of operation.

[0073] Optionally, the first locking mechanism 303 includes a threaded locking element. For example, see reference... Figure 4 As shown, the support 1 also includes a transition seat 105, which is connected to the upright 102, and the first guide structure 103 is disposed on the transition seat 105.

[0074] Optionally, the threaded locking member is threadedly connected to the first positioning member 301 and can abut or disengage from the support 1. Specifically, the threaded locking member is threadedly connected to the first adjusting seat 3011 and can abut or disengage from the adapter seat 105 of the support 1. When the threaded locking member abuts against the adapter seat 105, the first positioning member 301 is locked; when the threaded locking member disengages from the adapter seat 105, the locking of the first positioning member 301 is released.

[0075] Of course, the threaded locking member is not limited to being threadedly connected to the first positioning member 301. For example, in other embodiments not shown, the threaded locking member is threadedly connected to the support 1 and can abut or disengage from the first positioning member 301. Specifically, the threaded locking member is threadedly connected to the adapter 105 and can abut or disengage from the first adjusting seat 3011. Furthermore, a first locking mechanism 303 is provided in both the working position and the clearance position.

[0076] With this configuration, the first positioning component 301 can be locked in both the working position and the avoidance position. This ensures the stability of the first positioning component 301 in the working position and fixes it in the avoidance position after switching to prevent displacement.

[0077] In some embodiments provided by this utility model, the second positioning member 302 is movably connected to the support 1, for example, the second positioning member 302 is movably connected to the stand 102, for example, through a sliding connection or a rotational connection. The second positioning member 302 can move closer to or further away from the first positioning component 2 in the axial direction of the shock absorber 4. Optionally, the first positioning component 2 and the second positioning component 3 are arranged sequentially along the axial direction of the shock absorber 4, for example, referring to... Figure 3 As shown, in the usage state, at least a portion of the second positioning component 3 is located above the first positioning component 2.

[0078] In this embodiment, before placing the lower fork arm 5 and the shock absorber 4, the second positioning member 302 can be moved away from the first positioning component 2 to increase the operating space between the second positioning member 302 and the first positioning component 2, so as to facilitate the installation of the lower fork arm 5 and the shock absorber 4. After the shock absorber 4 is installed in place, the second positioning member 302 can be moved closer to the first positioning member 301 so that the second positioning member 302 is connected to the connecting plate 402 of the shock absorber 4.

[0079] After connecting the shock absorber 4 to the lower fork arm 5, the second positioning member 302 is moved away from the first positioning component 2 to increase the operating space between the second positioning member 302 and the first positioning component 2, so as to facilitate the removal of the lower fork arm 5 and the shock absorber 4 that are connected as one unit.

[0080] In some embodiments of this utility model, a second guide structure 104 is provided on the support 1, and a second positioning member 302 is slidably connected to the second guide structure 104. For example, the second guide structure 104 is a guide rail, the second guide structure 104 is mounted on the stand 102, and the extending direction of the second guide structure 104 is parallel to the axis of the shock absorber 4.

[0081] In this embodiment, the second positioning member 302 can be moved closer to or further away from the first positioning component 2 by sliding the second positioning member 302, without disassembling or replacing the components, thus improving operational efficiency.

[0082] Optionally, the sliding of the second positioning member 302 can be manually operated, or a reciprocating drive mechanism can be provided to drive the second positioning member 302 to slide. For example, the reciprocating drive mechanism includes, but is not limited to, a gear and rack drive mechanism, a lead screw and nut drive mechanism, a cylinder or a hydraulic cylinder.

[0083] Of course, the second positioning member 302 is not limited to a sliding connection with the support 1. For example, in other embodiments not shown, the second positioning member 302 can be rotatably connected to the support 1, and the axis of rotation of the second positioning member 302 is out of plane with the axis of the shock absorber 4, for example, perpendicular to it, so that the second positioning member 302 can be flipped up and down. In this way, the second positioning member 302 can be moved closer to or away from the first positioning component 2 by rotation.

[0084] refer to Figure 5 As shown, in some embodiments provided by this utility model, the second positioning member 302 includes a second adjusting seat 3021, a second mounting seat 3022, and a second positioning post 3023.

[0085] The second adjusting seat 3021 is movably connected to the support 1. For example, the second adjusting seat 3021 is slidably connected to the second guide structure 104, or the second adjusting seat 3021 is rotatably connected to the upright seat 102.

[0086] The second mounting base 3022 and the second adjusting base 3021 are detachably connected, for example, the second mounting base 3022 and the second adjusting base 3021 are screwed together.

[0087] The second positioning pin 3023 is disposed on the second mounting base 3022 and is used to limit the engagement with the second positioning hole 4021 of the connecting plate 402. For example, the second positioning pin 3023 is configured as a positioning pin or a positioning shaft. For example, when the second positioning pin 3023 is connected to the second positioning hole 4021 of the shock absorber 4, the second positioning pin 3023 extends downward.

[0088] In this embodiment, when connecting the shock absorber 4 to the second positioning member 302, the shock absorber 4 is first placed in position, and then the second adjusting seat 3021 is moved toward the direction of the first positioning component 2 so that the second positioning post 3023 passes into the second positioning hole 4021.

[0089] By mounting the second positioning pin 3023 onto the second mounting base 3022 and detachably connecting the second mounting base 3022 to the second adjusting base 3021, it is possible to replace the second mounting base 3022 with different sizes or shapes, thereby adjusting the position of the second positioning pin 3023. This allows the positioning fixture to be compatible with shock absorbers 4 with different positions of the second positioning hole 4021. Simultaneously, the connection between the second adjusting base 3021 and the support 1 does not need to be disconnected, thus reducing the difficulty of replacement.

[0090] Optionally, the second positioning post 3023 can be directly installed on the second mounting base 3022.

[0091] Of course, the second positioning post 3023 can also be indirectly mounted on the second mounting base 3022. For example, the second positioning component 302 also includes a second transition seat 3024, which is mounted on the second mounting base 3022, and the second positioning post 3023 is mounted on the second transition seat 3024. This arrangement facilitates adjusting the shape and relative position of the second mounting base 3022 and the second transition seat 3024 to ensure the positional accuracy of the second positioning post 3023.

[0092] refer to Figure 5As shown, the second positioning post 3023 is further connected to the second mounting base 3022 via at least two sequentially connected second transition seats 3024, so as to allow for more flexible adjustment of the position of the second positioning post 3023. Optionally, the number of second positioning posts 3023 is at least two, so that the second positioning posts 3023 can correspond one-to-one with the second positioning holes 4021 of the shock absorber 4.

[0093] Optionally, the second positioning post 3023 is detachably connected to the second mounting base 3022 to facilitate the replacement of second positioning posts 3023 of different diameters.

[0094] In some embodiments provided by this utility model, the second positioning component 3 further includes a second locking mechanism 304. The second locking mechanism 304 is disposed on the second positioning member 302 or the support 1, and can selectively lock the second positioning member 302 to the second guide structure 104 or release it.

[0095] In this embodiment, the second locking mechanism 304 achieves operational stability and ease of adjustment for the second positioning member 302 through selective fixing. For example, when positioning the shock absorber 4, the second locking mechanism 304 securely fixes the second positioning member 302 to the working area, ensuring accurate positioning. When installing or removing the shock absorber 4, releasing the lock allows the second positioning member 302 to move away from the first positioning component 2, preventing interference and improving the convenience of loading and unloading.

[0096] refer to Figure 5 As shown, optionally, the second locking mechanism 304 includes a threaded locking element.

[0097] Optionally, the threaded locking member is threadedly connected to the support 1 and can abut or disengage from the second positioning member 302. Specifically, the threaded locking member is threadedly connected to the upright 102 and can abut or disengage from the second adjusting seat 3021.

[0098] Furthermore, the support 1 is provided with two second locking mechanisms 304, which are arranged at intervals along the axial direction of the shock absorber 4. For example, assume that the second positioning member 302 can switch between a first position and a second position, and that when in the first position, the second positioning member 302 is connected to the shock absorber 4, and when in the second position, the second positioning member 302 is disengaged from the shock absorber 4. Accordingly, the two second locking mechanisms 304 are respectively provided in the first position and the second position.

[0099] Of course, the threaded locking element is not limited to being threadedly connected to the support 1. For example, in other embodiments not shown, the threaded locking element is threadedly connected to the second positioning element 302 and can abut or disengage from the support 1. Specifically, the threaded locking element is threadedly connected to the second adjusting seat 3021 and can abut or disengage from the upright 102. When the threaded locking element abuts against the upright 102, it can lock the second positioning element 302; when the threaded locking element disengages from the upright 102, it can release the locking of the second positioning element 302.

[0100] This configuration ensures the stability of the second positioning component 302 in the working position and fixes it in the avoidance position after switching, preventing the second positioning component 302 from shifting.

[0101] refer to Figures 1-3 As shown, in some embodiments provided by this utility model, the quantity of both the first positioning component 2 and the second positioning component 3 is at least two, and the first positioning component 2 and the second positioning component 3 correspond one-to-one. For example, the figure shows an example where the quantity of both the first positioning component 2 and the second positioning component 3 is two. For example, two first positioning components 2 are distributed on both sides of the stand 102, and two second positioning components 3 are distributed on both sides of the stand 102.

[0102] This configuration allows the positioning fixture to install the shock absorbers 4 and lower fork arms 5 on both sides of the vehicle, improving the efficiency of the fixture.

[0103] Furthermore, the first positioning element 301 of both first positioning components 2 is slidably connected to the first guide structure 103, that is, the two first positioning elements 301 share the first guide structure 103, thereby simplifying the tooling structure and reducing manufacturing costs while ensuring the positioning function.

[0104] refer to Figure 3 and Figure 6 As shown, in some embodiments provided by this utility model, the first positioning component 2 includes a third positioning member 201, which has a limiting hole 2011 for connecting with a pin hole 501 at the end of the lower fork arm 5 away from the shock absorber 4. For example, the pin hole 501 of the lower fork arm 5 is pin-connected to the limiting hole 2011 of the third positioning member 201.

[0105] In this embodiment, the third positioning member 201 is pinned to the pin hole 501 of the lower fork arm 5 through the limiting hole 2011, which can accurately limit the position of the lower fork arm 5 away from the shock absorber 4 and ensure the accurate installation posture of the lower fork arm 5.

[0106] Optionally, the third positioning member 201 is disposed between the two forks of the lower fork arm 5, and both ends of the third positioning member 201 are provided with limiting holes 2011, which correspond one-to-one with the pin holes 501 on the two forks. Of course, the two limiting holes 2011 of the third positioning member 201 can be connected.

[0107] In this embodiment, the third positioning member 201 is set between the two forks and has limiting holes 2011 at both ends. It can simultaneously dock with the pin holes 501 of the two forks to form a stable two-point positioning structure, which effectively prevents the lower fork 5 from shifting during the assembly process and improves the overall positioning accuracy.

[0108] In some embodiments provided by this utility model, the first positioning component 2 includes a fourth positioning member 202, which is provided with a limiting groove 2021. The limiting groove 2021 is used to insert the end of the lower fork arm 5 away from the shock absorber 4 and to limit the end of the lower fork arm 5 away from the shock absorber 4. Optionally, the two sidewalls of the limiting groove 2021 are distributed on both sides of the pin hole axis of the lower fork arm 5.

[0109] In this embodiment, the fourth positioning member 202 limits the end of the lower fork arm 5 through the limiting groove 2021. The groove-enclosed structure enables rapid positioning and stable clamping. The limiting groove 2021 is adapted to the shape of the lower fork arm 5, which can effectively limit its translation, ensure accurate installation position, simplify the assembly operation process, and improve positioning efficiency and reliability.

[0110] Optionally, the first positioning component 2 includes two fourth positioning elements 202, which respectively cooperate with the two forks of the lower fork arm 5.

[0111] In this embodiment, the two fourth positioning members 202 cooperate with the two forks of the lower fork arm 5 to form a double-sided limiting structure, which can simultaneously constrain the displacement and deflection of the two forks arm, effectively preventing the lower fork arm 5 from twisting due to uneven force during assembly, further improving positioning accuracy and reliability, and ensuring the alignment accuracy of the left and right forks arm and the shock absorber 4.

[0112] In some embodiments provided by this utility model, the first positioning component 2 includes a fifth positioning element 203 and a sixth positioning element 204.

[0113] The fifth positioning element 203 and the sixth positioning element 204 are arranged opposite to each other and spaced apart. The fifth positioning element 203 and the sixth positioning element 204 are distributed on both sides of the lower fork arm 5 and restrict the lower fork arm 5 between the fifth positioning element 203 and the sixth positioning element 204. For example, the fifth positioning element 203 and the sixth positioning element 204 are distributed on both sides of the axis of the pin hole 501 of the lower fork arm 5.

[0114] In this embodiment, the fifth positioning member 203 and the sixth positioning member 204 clamp the lower fork arm 5 on both sides, restricting its lateral swing or movement, forming a stable planar positioning constraint, which can accurately control the installation angle of the lower fork arm 5 and avoid assembly errors caused by offset.

[0115] This utility model embodiment also provides a production line.

[0116] Specifically, the production line includes the positioning fixtures described above.

[0117] It should be noted that the production line includes positioning fixtures, and therefore also includes all the advantages of positioning fixtures mentioned above.

[0118] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
