Description

Technical Field

[0001] The invention discloses a steering wheel wrapping method and belongs to the field of automobile interior decoration manufacturing. Background Art

[0002] Steering wheel wrapping refers to adding a layer of protective material to the outside of the steering wheel to achieve the effect of improving the driver's grip and anti-slip. The materials on the outside of the car steering wheel are generally plastic, leather, genuine leather, etc. These materials will accumulate dirt and fade, crack, peel, etc. after long-term use, so adding a protective cover is very necessary. There are many materials for protective covers, such as cloth, plush, leather, etc. When choosing, you must follow the principle of anti-slip to ensure driving safety. The leather steering wheel cover feels good, can improve the grade of the cabin, and is easier to take care of. In summer, you can choose a steering wheel cover with hollow cloth or genuine leather ventilation holes, and in winter, you can choose a plush steering wheel cover.

[0003] After the leather steering wheel cover is put on the steering wheel, the two sides of the steering wheel cover need to be sewed together with a needle bar. During the sewing process, the needle bar needs to move from one side of the steering wheel to the other side of the steering wheel and then back to the initial side, and perform a reciprocating operation to repeatedly adjust the insertion direction of the needle bar to sew the two sides together. This sewing operation takes a long time because it requires the needle bar to be inserted into multiple original thread holes on both sides of the steering wheel cover. In addition, because the needle bar repeatedly adjusts the insertion direction and the operating space of the steering wheel is limited, the needle bar can easily poke the operator's hand or other parts during the sewing process, which poses certain safety hazards. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a steering wheel wrapping method.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a steering wheel wrapping method, comprising the following steps:

[0006] The first step is to process the steering wheel cover, fix the hollow rubber body at the edge of the first side of the steering wheel cover, and open a plurality of through holes near the edge of the second side of the steering wheel cover;

[0007] The second step is to put the steering wheel cover on the steering wheel to achieve preliminary cover;

[0008] The third step is to fine-tune the position of the steering wheel cover mounted on the steering wheel so that the portion used to wrap the spokes is aligned with the spokes to achieve calibration of the cover;

[0009] Step 4: Use adhesive to fix the steering wheel cover to the steering wheel to achieve preliminary fixation;)

[0010] Step 5: insert the hollow rubber connecting column on the hollow rubber body connected to the edge of the first steering wheel cover through the corresponding through hole and remove it from the through hole, then use the pull wire to pass through the connecting ports on the plurality of hollow rubber connecting columns, and fix the two movable ends of the pull wire to the two sides of the second steering wheel cover edge respectively;

[0011] The sixth step is to puncture the hollow rubber body to discharge the gas in the hollow rubber body and the hollow rubber connecting column, thereby achieving a tightening connection between the steering wheel cover edge part 1 and the steering wheel cover edge part 2.

[0012] Furthermore, the step of putting the steering wheel cover on the steering wheel to achieve preliminary covering includes the following steps:

[0013] Adjust the steering wheel cover according to the direction of the steering wheel so that the steering wheel cover is aligned with the middle spoke;

[0014] Place the adjusted upper end of the steering wheel cover on top of the steering wheel;

[0015] Press the steering wheel cover down along the steering wheel to press the steering wheel cover onto the steering wheel to complete the initial installation.

[0016] Further, the steering wheel cover is heated before being attached to the steering wheel.

[0017] Furthermore, the adhesive is a double-sided tape, and before the steering wheel cover is put on the steering wheel, the double-sided tape is pasted on the edge of the inner side of the steering wheel cover where it contacts the steering wheel.

[0018] Furthermore, it also includes a leather case clamping step, and the leather case clamping step is between the fourth step and the fifth step;

[0019] The leather cover inserting step includes inserting the redundant leather cover portion of the steering wheel into the gap of the steering wheel.

[0020] Furthermore, before the steering wheel cover is installed on the steering wheel, dust and debris in the gap are cleaned using a tool.

[0021] Furthermore, before the steering wheel cover is put on the steering wheel, some lubricant is applied on the contact surface between the leather cover and the gap.

[0022] Furthermore, after the leather cover is inserted, the steering wheel cover is heated, and the edge position of the inserted portion of the steering wheel cover is pressed to adjust the shape so that it fits on the steering wheel.

[0023] Furthermore, a plurality of hollow rubber connecting columns are fixed to the side ends of the hollow rubber body, the hollow rubber body and the hollow rubber connecting columns are both hollow, the hollow rubber body and the hollow rubber connecting columns are internally connected, and contain gas for expanding the hollow rubber connecting columns.

[0024] Furthermore, the cross section of the hollow rubber connecting column is trapezoidal, and the diameter of the position close to the hollow rubber body is smaller than the diameter of the outer end of the hollow rubber connecting column.

[0025] The beneficial effects of the present invention are as follows: the hollow rubber connecting column on the hollow rubber body connected to the edge of the steering wheel cover part 1 is inserted into the corresponding through hole and removed from the through hole, and then a pull wire is used to pass through the connecting ports on multiple hollow rubber connecting columns, and the two movable ends of the pull wire are respectively sewn and fixed to the two sides of the steering wheel cover part 2 by a needle, wherein the pull wire only needs to pass through multiple connecting ports on one side and then be fixed to achieve the locking of the steering wheel cover part 1 and the steering wheel cover part 2. Compared with the traditional sewing operation, which requires the needle bar to pass through multiple thread holes 1 and 2 on both sides, half of the holes that the pull wire needs to be inserted through are saved, thereby greatly reducing the operation time, and during the needle threading process, the needle bar only needs to move in one direction, and there is no need to repeatedly adjust the insertion direction, thereby reducing the operation risk and improving the safety of use.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] See also Figure 1In the prior art, sewing threads are sewn on two edge positions (the original steering wheel cover edge 11 and the original steering wheel cover edge 2 12) of the leather steering wheel cover, and a plurality of thread holes 13 and thread holes 2 14 are formed between the sewing threads and the original steering wheel cover edge 11 and the original steering wheel cover edge 2 12, respectively. After the steering wheel cover is put on the steering wheel, the two sides of the steering wheel cover are sewn together with thread using a needle bar 16, that is, the connecting thread 15 is first passed through the thread hole 13 and then through the thread hole 2 14, and then through the next thread hole. One 13 and a thread hole two 14, and so on, by passing through multiple thread holes 13 and thread holes two 14, the original steering wheel cover edge part 11 and the original steering wheel cover edge part 2 12 are connected together. The sewing operation requires the use of a needle bar 16 to pass through multiple thread holes 13 and thread holes two 14 on both sides, so it takes a long time, and during the threading process, the needle bar 16 needs to repeatedly adjust the insertion direction, and the operating space of the steering wheel position is limited. Therefore, during the sewing process, the needle bar is easy to poke the operator's hand or other parts, which has certain safety hazards.

[0033] To resolve this technical issue, see Figure 2 , provides a technical solution: a steering wheel wrapping method, comprising the following steps:

[0034] The first step is to further process the steering wheel cover, fix the hollow rubber body 3 at the edge of the steering wheel cover edge 1, and process a plurality of through holes 21 near the edge of the steering wheel cover edge 2;

[0035] A plurality of hollow rubber connecting columns 31 are fixed to the side ends of the hollow rubber body 3. The insides of the hollow rubber body 3 and the hollow rubber connecting columns 31 are both hollow. The insides of the hollow rubber body 3 and the hollow rubber connecting columns 31 are connected, and gas is contained therein to expand the hollow rubber connecting columns 31, so as to facilitate the insertion of the hollow rubber connecting columns 31 into the through holes 21, thereby realizing convenient installation of the hollow rubber connecting columns 31 and the through holes 21. In addition, a connecting port 32 is provided on the hollow rubber connecting column 31, and the connecting port 32 is used to connect with the pull wire 4.

[0036] Preferably, the steering wheel cover rim 1 and the hollow rubber body 3 can be connected by means of adhesive, sewing thread or ultrasonic welding;

[0037] Preferably, the hollow rubber body 3 and the hollow rubber connecting column 31 can be connected by means of glue or the like. When processing the hollow rubber body 3, holes can be processed on the surface of the hollow rubber body 3 to fill the hollow rubber body 3 with gas. After a sufficient amount of gas is filled, the inflated holes are sealed by means of gluing or the like, so that gas remains inside the hollow rubber body 3 and the hollow rubber connecting column 31.

[0038] The second step is to adjust the position of the steering wheel cover according to the direction of the steering wheel, align the steering wheel cover with the middle spoke and place the upper end of the adjusted steering wheel cover on the top of the steering wheel, and press the steering wheel cover down along the steering wheel to press the steering wheel cover onto the steering wheel to complete the initial installation.

[0039] Preferably, in order to facilitate the installation of the steering wheel cover, the steering wheel cover can be heated before being put on the steering wheel. Specifically, the steering wheel cover can be heated by blowing hot air from a hair dryer, so that the steering wheel cover can produce a certain expansion effect due to the principle of thermal expansion and contraction, thereby facilitating wrapping of the steering wheel.

[0040] Preferably, when the steering wheel cover is too tight to be wrapped around the steering wheel, a two-person cooperative installation method is used to install the steering wheel cover, one of whom places the upper end of the steering wheel cover after the direction is adjusted on the top of the steering wheel and presses the steering wheel cover on the top of the steering wheel with his hand, and the other person stretches the steering wheel cover downward and presses it on other positions of the steering wheel except the top, to achieve preliminary installation of the steering wheel.

[0041] The third step is to fine-tune the position of the steering wheel cover on the steering wheel, align the part used to wrap the spokes with the spokes, and calibrate the cover. During the adjustment process, the steering wheel can be rotated to facilitate adjustment of the position of the steering wheel cover along the circumferential direction of the steering wheel and the front and rear position of the steering wheel cover relative to the steering wheel.

[0042] The fourth step is to use adhesive to fix the steering wheel cover on the steering wheel to achieve preliminary fixation;

[0043] The adhesive may be a double-sided tape. Before putting the steering wheel cover on the steering wheel, stick the double-sided tape on the edge of the inner side of the steering wheel cover where it contacts the steering wheel. After the third step, tear off the protective paper on the outer side of the double-sided tape and stick the steering wheel cover on the steering wheel using the double-sided tape.

[0044] Preferably, when tearing off the protective paper on the outside of the double-sided tape, tear them off one by one instead of all at once. Press and fix each point after tearing it off to ensure that the steering wheel cover will not move during sewing and to make the steering wheel cover fit more closely to the steering wheel.

[0045] When installing some steering wheel covers, you need to insert the extra leather part of the steering wheel cover into the gap of the steering wheel to make it more beautiful and fit. Before inserting it, you can use some tools such as plastic scrapers or credit cards to clean the dust and debris in the gap to ensure that the gap is wide enough;

[0046] At the same time, you can use some lubricant such as soapy water or lubricant spray to apply on the contact surface of the holster and the gap to reduce friction and make the holster easier to insert.

[0047] After the leather cover is inserted, you can gently press the leather cover with your hands or tools to make it fit more closely to the surface of the steering wheel. If you find obvious bulges or dents, you can use a heat gun or hair dryer to heat the steering wheel cover appropriately to make it softer and easier to adjust the shape.

[0048] The fifth step is to insert the hollow rubber connecting column 31 on the hollow rubber body 3 connected to the edge of the steering wheel cover 1 into the corresponding through hole 21 and remove it from the through hole 21, and then use the pull wire 4 to pass through the connecting ports 32 on the multiple hollow rubber connecting columns 31, and sew the two movable ends of the pull wire 4 to the two sides of the steering wheel cover 2 with needles.

[0049] like Figure 3 As shown, the cross-section of the hollow rubber connecting column 31 is trapezoidal, and the diameter near the hollow rubber body 3 is smaller than the diameter of the outer end of the hollow rubber connecting column 31. This design ensures that after the hollow rubber connecting column 31 and the through hole 21 are clamped together, the hollow rubber connecting column 31 and the through hole 21 will not be easily separated, thereby improving the stability of the connection between the two.

[0050] The sixth step is to puncture the hollow rubber body 3 to discharge the gas in the hollow rubber body 3 and the hollow rubber connecting column 31, so as to realize the tightening connection between the steering wheel cover edge part 1 and the steering wheel cover edge part 2. After the hollow rubber body 3 is punctured, the gas in the hollow rubber body 3 and the hollow rubber connecting column 31 is discharged, and the hollow rubber body 3 and the hollow rubber connecting column 31 are changed from three-dimensional to flat, so as to realize the stable connection without affecting the hand feeling of the driver holding the steering wheel cover, and the hollow rubber connecting column 31 itself is elastic, so that the steering wheel cover can be tightly wrapped on the steering wheel;

[0051] Preferably, a plurality of blocking blocks 5 are fixed on the edge of the steering wheel cover portion 2 to limit the pull wire 4 and prevent the pull wire 4 from moving too much toward the steering wheel cover portion 1, thereby ensuring that the steering wheel cover portion 1 and the steering wheel cover portion 2 are stably connected.

[0052] In this design, the pull wire 4 only needs to pass through multiple connecting ports 32 on one side and then be fixed to achieve the locking of the steering wheel cover edge part 1 and the steering wheel cover edge part 2. Compared with the traditional sewing operation that requires the use of the needle bar 16 to pass through multiple thread holes 13 and thread holes 14 on both sides, the amount of holes that the pull wire 4 needs to be inserted through is eliminated, the operation time is greatly reduced, and during the threading process, the needle bar only needs to move in one direction, and there is no need to repeatedly adjust the insertion direction, which reduces the risk of operation and improves the safety of use.

[0053] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
