Description

Technical Field

[0001] This application relates to the field of vehicle interiors, and more particularly to a scribing tool. Background Technology

[0002] Currently, the automotive interior sector is seeing a surge in the use of PVC, PU, ​​silicone leather, and even genuine leather for surface coverings. Because these materials almost universally suffer from poor compatibility, friction and rattling noises can easily occur when these covered components rub against each other (as shown in the image below), significantly reducing the perceived quality for end-users.

[0003] In related technologies, resolving frictional noise between covered decorative components typically involves adding noise-reducing filler between the mating components. To ensure the precision of felt adhesion, two technical solutions exist:

[0004] (1) During the design phase, an initial structure is added to the skeleton of the covering. However, the initial structure is generally an additional structure added to the skeleton based on experience and cost considerations. It is easy to omit or lack feasibility. If the covering requires a back bubble layer to increase perceived quality, the back bubble layer will cover the initial structure after the skin is reversed, affecting the accuracy of felt pasting. (2) The control of felt pasting samples requires diverse replication. If each sample cannot be consistent, it will cause delays in the mass production period. In addition, the samples need to be placed on the production site for a long time. If they age or are lost, they need to be re-approved, which will easily delay the production cycle. Summary of the Invention

[0005] This application provides a scribing tool.

[0006] This application provides a scribing tool, including: a first adjusting member and a second adjusting member, wherein the second adjusting member is adjustablely connected to the first adjusting member in a first direction;

[0007] The second adjusting member has an abutting portion at one end in the first direction, and the first adjusting member has an engraving portion at the same end in the first direction; the engraving portion extends from the first adjusting member toward the second adjusting member and is spaced apart from the abutting portion along the first direction, and the end of the engraving portion away from the first adjusting member and toward the abutting portion is the engraving portion.

[0008] The gap between the abutment and the engraving part is used to accommodate the workpiece to which the felt needs to be bonded. By adjusting the relative positions of the first and second adjusting parts, the size of the gap between the abutment and the engraving part can be adjusted to accommodate workpieces of different sizes, thereby improving the applicability of the scribing tool. The engraving part is located on the side of the engraving part facing the abutment. After the workpiece is accommodated between the abutment and the engraving part, by moving the scribing tool, an engraving line representing the starting position for felt bonding can be left on the workpiece, indicating the starting position for felt bonding. Workers can observe the starting line to bond the felt within the standard requirements, thereby ensuring the accuracy of felt bonding.

[0009] Optionally, the engraving element is hook-shaped, and the engraving portion extends toward the first adjusting element to form a hook-shaped protrusion.

[0010] Optionally, the first adjusting member is provided with a scale portion, the scale portion including a plurality of scale lines arranged along the first direction; the side of the abutting portion facing the engraving member is a plane, the plane being perpendicular to the first direction.

[0011] Optionally, a first anti-friction element is provided covering the engraved portion.

[0012] Optionally, the second adjusting member is located below the first adjusting member along a second direction, and the second direction is perpendicular to the first direction;

[0013] The engraving element extends downward along the second direction and protrudes from the top surface of the second adjusting element.

[0014] Optionally, the abutting portion extends downward along the second direction and protrudes from the second adjusting member.

[0015] Optionally, the first adjusting member includes a connecting portion, and the second adjusting member includes a mating portion. The number of at least one of the connecting portion and the mating portion is multiple, and they are arranged along the first direction. When the second adjusting member and the first adjusting member are adjusted to their respective positions, at least one pair of the connecting portion and the mating portion correspond in position.

[0016] The scribing device also includes a fixing member, which is detachably inserted through the connecting part and the mating part at the corresponding positions to fix the first adjusting member and the second adjusting member.

[0017] Optionally, the first adjusting member has a groove on the side facing the second adjusting member, the connecting part is disposed on the side wall of the groove, and the groove extends along the first direction;

[0018] The second adjusting member has a slider on the side facing the first adjusting member. The slider extends along the first direction and is slidably disposed in the groove.

[0019] Optionally, the second adjusting member is located below the first adjusting member along a second direction, and the second direction is perpendicular to the first direction;

[0020] The slide groove extends into the slide groove along at least one side wall in the third direction near one end of the second adjusting member to form an engaging portion. The engaging portion and the connecting portion are arranged along the second direction. The third direction is perpendicular to the first direction and the second direction.

[0021] The slider has a groove on its side along the third direction that is adapted to the engaging part, and the engaging part engages in the groove.

[0022] Optionally, a second anti-friction member is also included, which covers the surface of the engaging portion that contacts the groove.

[0023] Optionally, the connecting part is a connecting hole, the mating part is a mating hole, and the fixing member is a stud that is adapted to the connecting hole and the mating hole.

[0024] Optionally, the engraving element is integrally formed with the first adjusting element.

[0026] Optionally, the first adjusting member is made of steel.

[0027] Optionally, the second adjusting element is an elastic injection molded part.

[0028] By marking the surface of the covered trim to indicate the starting position for felt bonding, the aforementioned processing method avoids the need to consider the felt bonding starting structure in the design phase of the covered skeleton. This prevents situations where insufficient mold and cost feasibility prevent the addition of felt. When the covered trim requires a back bubble layer to enhance perceived quality, the back bubble layer does not interfere with the marking on the surface and does not affect the accuracy of felt bonding. Thus, rework time for workpieces requiring felt bonding is reduced during production, improving production efficiency; the accuracy of felt bonding is improved, and the overall quality of the workpiece is enhanced.

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0037] This application provides a scribing tool. The scribing tool of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0038] This application provides a scribing tool 100, see [link]. Figure 1 and Figure 2As shown, the device includes a first adjusting member 10 and a second adjusting member 20. The second adjusting member 20 is adjustablely connected to the first adjusting member 10 in a first direction X. One end of the second adjusting member 20 in the first direction X has an abutment portion 21, and the same end of the first adjusting member 10 in the first direction X has an engraving member 30. The engraving member 30 extends from the first adjusting member 10 toward the second adjusting member 20 and is spaced apart from the abutment portion 21 along the first direction X. The end of the engraving member 30 away from the first adjusting member 10 and facing the abutment portion 21 is an engraving portion 31, which is used to leave an engraving on the outer covering trim to indicate the starting position for pasting the felt.

[0039] The gap between the abutment portion 21 and the engraving part 30 is used to accommodate the workpiece to which the felt needs to be pasted, and can engage with the edge of the workpiece to be engraved. By moving the engraving tool 100 along the edge of the workpiece, the engraving portion 31 leaves an engraving on the workpiece. By adjusting the relative positions of the first adjusting member 10 and the second adjusting member 20, the size of the gap between the abutment portion 21 and the engraving part 30 can be adjusted to accommodate workpieces of different sizes, thereby improving the applicability of the engraving tool 100. The engraving portion 31 is located on the side of the engraving part 30 facing the abutment portion 21. After the workpiece is accommodated between the abutment portion 21 and the engraving part 30, by moving the engraving tool 100, the engraving portion 31 can leave an engraving on the workpiece to represent the starting line for felt pasting, indicating the starting position for felt pasting. Workers can observe the starting line to paste the felt within the standard requirements, thereby ensuring the accuracy of felt pasting.

[0040] By leaving engravings on the surface covering to indicate the starting position of the felt bonding, the above processing method avoids the need to consider the starting structure of the felt bonding on the covering skeleton during the design stage. This avoids situations where insufficient mold and cost feasibility prevent the addition of the felt. When the covering requires a back bubble layer to increase perceived quality, the back bubble layer will not interfere with the engraving on the surface and will not affect the accuracy of the felt bonding.

[0041] In an optional embodiment, see Figure 1 As shown, the embossed part 30 is hook-shaped, and the embossed portion 31 extends toward the first adjusting member 10 to form a hook-shaped protrusion. The hook-shaped protrusion can extend along a third direction Z, that is, the shape of the protrusion is a straight line. The third direction Z is perpendicular to the first direction X. In other embodiments, the side of the embossed part 30 facing the abutment portion 21 can also be set as a plane, and the embossed portion 31 extends from the plane toward a tip close to the abutment portion 21. The tip can be set as a cone shape or as a shape extending along the third direction Z.

[0042] With the above configuration, the engraving part 31 is recessed in the direction away from the abutting part 21 in the part away from the hook-shaped protrusion, so as to facilitate the accommodation of the workpiece that needs to be pasted with felt. The hook-shaped protrusion is used to leave an engraving on the workpiece, simplifying the overall structure of the engraving part 30 and facilitating the manufacture of the engraving tool 100.

[0043] In an optional embodiment, see Figure 1 As shown, the first adjusting member 10 is provided with a scale portion 11, which includes a plurality of scale lines 111 arranged along the first direction. The side of the abutment portion 21 facing the engraving member 30 is a plane, which is perpendicular to the first direction X. With the above arrangement, it is convenient to align the side of the abutment portion 21 facing the engraving member 30 with the scale lines 111 on the scale portion 11. Therefore, when processing the workpiece, it is convenient to set the relative position between the first adjusting member 10 and the second adjusting member 20, so that the gap between the engraving member 30 and the abutment portion 21 can accommodate the workpiece and engage with it, thereby facilitating the processing of the workpiece.

[0044] In an optional embodiment, the first adjusting member 10 is further provided with a limiting portion, which is used to limit the movement of the second adjusting member 20 relative to the first adjusting member 10 in the first direction X, thereby limiting the minimum gap between the engraving member 30 and the abutment portion 21. When the second adjusting member 20 abuts against the limiting portion, the plane of the abutment portion 21 is flush with the starting position of the scale portion 11, thereby ensuring the adjustment accuracy of the engraving device 100.

[0045] In an optional embodiment, see Figure 1 As shown, the scribing tool 100 includes a first anti-friction member 40, which is disposed over the engraving portion 31. In this embodiment, the first anti-friction member 40 may be felt. This application does not specifically limit the material of the first anti-friction member 40, as long as it can reduce the frictional wear caused by the scribing tool 100 on the surface of the workpiece during relative movement between the scribing tool 100 and the workpiece. With the above arrangement, when the gap between the abutment portion 21 and the engraving member 30 accommodates the workpiece to which the felt needs to be pasted, and engages with the edge of the workpiece to be engraved and moves along the edge of the workpiece, the wear caused by the scribing tool 100 on the workpiece can be reduced, protecting the workpiece, and at the same time, it is beneficial to the accuracy of the starting line of the engraved felt pasting.

[0046] In an optional embodiment, the first anti-friction member 40 is disposed over the abutment portion 21.

[0047] In an optional embodiment, the second adjusting member 20 is located below the first adjusting member 10 along the second direction Y, which is perpendicular to the first direction X. The engraving member 30 extends downward along the second direction Y and protrudes from the top surface of the second adjusting member 20.

[0048] This allows the engraving part 30 and the abutment part 21 to clamp both ends of the workpiece in the first direction X, which is beneficial for positioning the engraving part 31 on the workpiece. When the engraving device 100 moves and leaves an engraving starting line representing the felt pasting on the workpiece through the engraving part 31, it is beneficial for the accuracy of the engraving starting line.

[0049] In an optional embodiment, the abutment portion 21 extends downward along the second direction Y and protrudes from the second adjusting member 20.

[0050] This increases the size of the abutment part 21, which can clamp the workpiece, making it easier for the scribing tool 100 to be positioned on the workpiece. This improves the applicability of the scribing tool 100 and helps to improve the accuracy of the scribing starting line when the scribing tool 100 is moved and the scribing part 31 leaves a scribing starting line on the workpiece to represent the felt pasting.

[0051] In an optional embodiment, the first adjusting member 10 includes a connecting portion 12, and the second adjusting member 20 includes a mating portion 22. There are multiple connecting portions 12 and mating portions 22, arranged along a first direction X. When the second adjusting member 20 and the first adjusting member 10 are adjusted to their respective positions, at least one pair of connecting portions 12 and mating portions 22 correspond in position. The scribing device 100 also includes a fixing member 60, which is detachably inserted through the corresponding connecting portions 12 and mating portions 22 to fix the first adjusting member 10 and the second adjusting member 20.

[0052] With the above setup, before engraving the workpiece, the relative positions of the first adjusting member 10 and the second adjusting member 20 are adjusted according to the shape of the workpiece, so that the gap between the engraving member 30 and the abutment portion 21 can accommodate the workpiece. Then, the fixing member 60 is inserted through the connecting portion 12 and the mating portion 22 to fix the relative positions of the first adjusting member 10 and the second adjusting member 20. During the process of moving the engraving tool 100 and leaving the starting line representing the felt bonding on the workpiece through the engraving part 31, it is ensured that the size of the gap between the engraving member 30 and the abutment portion 21 does not change, which is beneficial to the accuracy of the engraved starting line for felt bonding.

[0053] In an optional embodiment, the first adjusting member 10 has a groove 13 on the side facing the second adjusting member 20, and the connecting part 12 is disposed on the side wall of the groove 13, which extends along the first direction X. The second adjusting member 20 has a slider 23 on the side facing the first adjusting member 10, which extends along the first direction X and is slidably disposed in the groove 13.

[0054] Thus, the second adjusting member 20 is slidably connected relative to the first adjusting member 10 in the first direction X. Furthermore, through the above arrangement, the connecting part 12 and the mating part 22 only need to be aligned in the second direction Y, facilitating the fastener 60 to pass through the connecting part 12 and the mating part 22 to fix the relative position of the first adjusting member 10 and the second adjusting member 20, thereby facilitating the use of the scribing tool 100.

[0055] In alternative embodiments, the first adjusting member 10 and the second adjusting member 20 can also be fixed by engaging. In other embodiments, the first adjusting member 10 and the second adjusting member 20 can also be fixed by adding damping.

[0056] In an optional embodiment, the second adjusting member 20 is located below the first adjusting member 10 along the second direction Y, which is perpendicular to the first direction X. The slide groove 13 extends along at least one sidewall in the third direction Z, near one end of the second adjusting member 20, and forms a locking portion 14 extending into the slide groove 13 along the third direction Z. The locking portion 14 and the connecting portion 12 are arranged along the second direction Y. The third direction Z is perpendicular to both the first direction X and the second direction Y. The slider 23 has a groove on its side along the third direction Z that matches the locking portion 14, and the locking portion 14 engages within the groove.

[0057] The engagement between the locking part 14 and the groove enables the second adjusting member 20 and the first adjusting member 10 to be positioned in the second direction Y. This allows the connecting part 12 and the mating part 22 to be aligned only in the second direction Y. This facilitates the fastener 60 to pass through the connecting part 12 and the mating part 22 to fix the relative positions of the first adjusting member 10 and the second adjusting member 20, thereby facilitating the use of the scribing tool 100.

[0058] In an optional embodiment, the scribing device 100 further includes a second anti-friction member 50, which covers the surface of the engaging portion 14 that contacts the groove. In this embodiment, the second anti-friction member 50 is felt. This application does not specifically limit the material of the second anti-friction member 50, as long as it can reduce the frictional loss generated during the relative movement of the first adjusting member 10 and the second adjusting member 20.

[0059] In this way, the frictional loss between the first adjusting member 10 and the second adjusting member 20 during the relative movement can be reduced, which is beneficial to the accuracy of the scribing device 100 during long-term use and to the service life of the scribing device 100.

[0060] In an optional embodiment, the connecting part 12 is a connecting hole, the mating part 22 is a mating hole, and the fixing member 60 is a stud that is adapted to the connecting hole and the mating hole.

[0061] The above-described configuration simplifies the structure between the connecting part 12 and the mating part 22. Simultaneously, connecting the connecting hole and the mating part with studs ensures the reliability of the first and second adjusting parts being secured by the fastener 60. This reduces the need for the marking part 31 to leave the starting line for felt adhesion on the workpiece during use, ensuring that the gap between the marking part 30 and the abutment part 21 remains unchanged, thus improving the accuracy of the marked starting line for felt adhesion.

[0062] In an optional embodiment, the etched part 30 is integrally formed with the first adjusting member 10. This facilitates the manufacture of the scribing tool 100. It also ensures that the spacing between the contact portion 21 and the etched part 30 remains consistent each time the first adjusting member 10 and the second adjusting member 20 are adjusted.

[0063] In an optional embodiment, the abutment portion 21 and the second adjusting member 20 are integrally formed. This facilitates the manufacture of the scribing tool 100. It ensures that the spacing between the abutment portion 21 and the etched member 30 remains consistent each time the first adjusting member 10 and the second adjusting member 20 are adjusted.

[0064] In an optional embodiment, the first adjusting member 10 is made of steel. Furthermore, the first adjusting member 10 is precision machined. When the first adjusting member 10 is provided with a scale portion 11, it helps to ensure the accuracy of the scale portion 11 during processing and use.

[0065] In an optional embodiment, the second adjusting member 20 is an elastic injection molded part. Further, the second adjusting member 20 is injection molded using a TPU-type thermoplastic elastomer. When the engraving member 30 and the abutment portion 21 clamp the workpiece from both sides in the first direction X, the elasticity of the second adjusting portion can reduce wear on the workpiece by the scribing tool 100, thereby facilitating the use of the scribing tool 100.

[0066] When using the scribing tool 100, the relative positions of the first adjusting member 10 and the second adjusting member 20 are adjusted so that the gap between the abutment portion 21 and the engraving member 30 can accommodate the workpiece to which the felt needs to be pasted. Then, the relative positions of the first adjusting member 10 and the second adjusting member 20 are fixed by the fixing member 60 passing through the connecting portion 12 and the mating portion 22. At this time, the scale line 111 corresponding to the abutment portion 21 can be recorded for processing other identical workpieces. By moving the scribing tool 100 along the edge of the workpiece, the engraving member 31 leaves an imprint on the workpiece to be engraved, representing the starting line for felt pasting and indicating the starting position for felt pasting. Workers can observe the starting line to paste the felt within the standard requirements, thus ensuring the accuracy of felt pasting.

[0067] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
