Description

Technical Field

[0001] This utility model relates to the field of harvesters, and in particular to a mounting structure for the end seat of the inner armrest of a vehicle door. Background Technology

[0002] The handrail inside the harvester door is a structure that allows the driver or passenger to open and close the door from the inside of the cab. It serves to reduce pressure on the driver's or passenger's shoulders, neck, and arms, maintain a natural sitting posture, and support the arms.

[0003] Currently, the two ends of the harvester door handle structure are fixed to the door glass by welding and standard parts screwing, respectively. The welding and screwing points on the door glass are often fixed. The welding structure between the door handle and the mounting plate has problems such as welding deformation and dimensional deviation, resulting in poor assembly accuracy, difficulty in assembly and adjustment, and easy jamming when the door is opened and closed. To solve this problem, it is necessary to improve the manufacturing accuracy of each component and the welding accuracy, which leads to an increase in the manufacturing cost of the components. The door handle is fixed to the door glass by standard parts screwing, leaving the standard parts in an exposed state, which is easy to be damaged. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mounting structure for the end seat of the inner armrest of a car door, so as to solve the above-mentioned problem.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A door inner armrest end seat mounting structure includes: a first armrest end mounting assembly, a second armrest end mounting assembly, an armrest support assembly, and a door armrest. The armrest support assembly includes a support base and a limiting cover. The second armrest end mounting assembly includes an inner armrest adjustment cover and an outer armrest adjustment cover. The support base is detachably mounted on the first armrest end mounting assembly, and the limiting cover is detachably mounted on the support base. The support base and the limiting cover are fixedly sleeved on one end of the door armrest. The inner armrest adjustment cover is slidably sleeved on the other end of the door armrest, and the outer armrest adjustment cover is fixedly sleeved on the inner armrest adjustment cover.

[0006] The beneficial effects of this utility model are as follows: Compared with the welding structure between the door armrest and the mounting plate in the prior art, this utility model detachably installs the support base on the first armrest end mounting assembly, and the limiting cover is detachably installed on the support base. The support base and the limiting cover are fixedly sleeved on one end of the door armrest, and the armrest adjustment inner cover is slidably sleeved on the other end of the door armrest. This facilitates fixing one end of the door armrest to the first armrest end mounting assembly during the assembly process, while adjusting its connection position with the second armrest end mounting assembly, avoiding difficulties in assembly and adjustment due to deviations in component dimensions. The armrest adjustment outer cover is fixedly sleeved on the armrest adjustment inner cover, which helps to prevent the standard part that fixes the armrest adjustment inner cover to the door glass from being exposed, reducing the risk of damage, extending the service life, and enhancing the aesthetics.

The distance between the two arc surfaces is adapted to the inner diameter of the limiting section.

[0013] The beneficial effect of adopting the above-mentioned further solution is that it allows the connecting block to enter the limiting section through the entry channel section after the orientation is adjusted, and then the orientation is adjusted again so that the connecting block cannot enter the entry channel section from inside the limiting section, thereby achieving the limiting of the support seat.

[0014] Furthermore, the support body is a U-shaped structure with its opening facing the door armrest. A second limiting groove is provided on one side wall of the opening end of the support body, and a third limiting groove is provided on the other end.

The limiting cover is detachably installed in the second limiting groove and the third limiting groove.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the support body is a U-shaped structure with its opening facing the door armrest, which is conducive to the fixed installation of the door armrest with the limiting cover; the third limiting groove and hinge hole, together with the elastic cylindrical pin, are conducive to the hinge connection of one end of the limiting cover with the support body; the second limiting groove is an arc-shaped channel that penetrates the side wall of the support body, which is conducive to the locking of the other end of the limiting cover with the support body, thereby realizing the fixation between the support body and the limiting cover.

[0016] Furthermore, the limiting cover is a shell structure with an arc-shaped inner wall. The two ends of the limiting cover are fixed with a first limiting protrusion and a second limiting protrusion respectively. The first limiting protrusion is rotatably set in the third limiting groove by an elastic cylindrical pin. The elastic cylindrical pin passes through the hinge hole and the first limiting protrusion. The second limiting protrusion is engaged with the second limiting groove.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the first limiting protrusion is rotatably set in the third limiting groove by an elastic cylindrical pin, which is conducive to hinged connection between one end of the limiting cover and the support body; the second limiting protrusion is engaged with the second limiting groove, which is conducive to fixing the support and the limiting cover, thereby fixing one end of the door armrest in the armrest support assembly.

[0018] Furthermore, the support body and the limiting cover are fixedly sleeved on one end of the door armrest. A second positioning protrusion is fixedly provided at the bottom end of the inner wall of the support body.

[0028] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] like Figures 1 to 9As shown, this embodiment provides a door inner armrest end mount mounting structure, including: a first armrest end mount assembly 1, a second armrest end mount assembly 2, an armrest support assembly 3, and a door armrest 4. The armrest support assembly 3 includes a support base 31 and a limiting cover 32. The second armrest end mount assembly 2 includes an armrest adjustment inner cover 21 and an armrest adjustment outer cover 22. The support base 31 is detachably mounted on the first armrest end mount assembly 1, and the limiting cover 32 is detachably mounted on the support base 31. The support base 31 and the limiting cover 32 are fixedly sleeved on one end of the door armrest 4. The armrest adjustment inner cover 21 is slidably sleeved on the other end of the door armrest 4, and the armrest adjustment outer cover 22 is fixedly sleeved on the armrest adjustment inner cover 21.

[0030] The beneficial effects of this utility model are as follows: Compared with the welding structure between the door armrest and the mounting plate in the prior art, this utility model detachably installs the support base on the first armrest end mounting assembly, and the limiting cover is detachably installed on the support base. The support base and the limiting cover are fixedly sleeved on one end of the door armrest, and the armrest adjustment inner cover is slidably sleeved on the other end of the door armrest. This facilitates fixing one end of the door armrest to the first armrest end mounting assembly during the assembly process, while adjusting its connection position with the second armrest end mounting assembly, avoiding difficulties in assembly and adjustment due to deviations in component dimensions. The armrest adjustment outer cover is fixedly sleeved on the armrest adjustment inner cover, which helps to prevent the standard part that fixes the armrest adjustment inner cover to the door glass from being exposed, reducing the risk of damage, extending the service life, and enhancing the aesthetics.

[0031] Preferred, such as Figure 2 and Figure 4 As shown, the first handrail end mounting assembly 1 includes a fixing plate 11 and a locking plate 12. The locking plate 12 is fixedly mounted on the side wall of the fixing plate 11. A locking gap 13 is provided between the fixing plate 11 and the locking plate 12. A first limiting groove 14 is provided on the side of the locking plate 12. The first limiting groove 14 communicates with the locking gap 13. The support base 31 rotatably passes through the first limiting groove 14.

[0032] The advantages of adopting the above preferred solution are: the first limiting groove is provided on the side of the locking plate, which is conducive to the support seat entering from the side of the locking plate and passing through the first limiting groove, thereby limiting the support seat.

[0033] Preferred, such as Figure 3 , Figure 6 and Figure 7As shown, the support base 31 includes: a support base body 311, a connecting block 312, and a limiting plate 313. The support base body 311 and the limiting plate 313 are fixedly connected to both ends of the connecting block 312 in a one-to-one correspondence. The longitudinal section of the connecting block 312 is formed by connecting two oppositely arranged arc surfaces 3121 and two oppositely arranged planes 3122 in sequence. The connecting block 312 is rotatably disposed in the first limiting groove 14. The limiting plate 313 is disposed in the locking gap 13. The limiting cover 32 is detachably installed on the support base body 311.

[0034] It should be noted that in this embodiment, the connecting block 312 is the part left after a cylinder is vertically cut from top to bottom and symmetrically with two cuts.

[0035] The advantages of adopting the above preferred solution are: the longitudinal section of the connecting block is formed by two oppositely arranged arc surfaces and two oppositely arranged planes connected in sequence, which is beneficial to allow the connecting block to enter the first limiting groove from the side of the locking plate, and then adjust the orientation of the connecting block by rotating the support base, so that the first limiting groove can limit the connecting block.

[0036] Preferred, such as Figure 6 and Figure 7 As shown, the first limiting groove 14 includes an entry channel section 141 and a limiting section 142. The limiting section 142 is a circular through hole. The entry channel section 141 is a channel connecting the limiting section 142 and the side of the locking plate 12. The inner diameter of the limiting section 142 is greater than the width of the entry channel section 141. The width of the entry channel section 141 is greater than the distance between the two planes 3122 and less than the distance between the two arc surfaces 3121. The distance between the two arc surfaces 3121 is adapted to the inner diameter of the limiting section 142.

[0037] It should be noted that since the shape of the limiting segment 142 is not fixed, it can be a parallel channel or a trapezoidal channel. Therefore, the "width of the entry channel segment 141" refers to the distance between the two connection points of the entry channel segment 141 and the limiting segment 142. In this embodiment, the connecting block 312 is formed by vertically cutting a cylinder from top to bottom with two symmetrical cuts. Therefore, "the distance between the two arc surfaces 3121" refers to the original diameter of the cylinder, which is the distance between the arc vertices of the two arc surfaces 3121. "Matching the inner diameter of the limiting segment 142" means that the distance between the two arc surfaces 3121 is slightly smaller than the inner diameter of the limiting segment 142, so that the connecting block 312 can rotate smoothly within the limiting segment 142.

[0038] The advantages of adopting the above preferred scheme are: it allows the connecting block to enter the limiting section through the entry channel after the orientation is adjusted, and then the orientation is adjusted again so that the connecting block cannot enter the entry channel from inside the limiting section, thereby limiting the support seat.

[0039] Preferred, such as Figure 6 and Figure 7 As shown, the support body 311 is a U-shaped structure with its opening facing the door armrest 4. A second limiting groove 314 is provided on one side wall of the opening end of the support body 311, and a third limiting groove 315 is provided on the other side end. The second limiting groove 314 is an arc-shaped channel that penetrates the side wall of the support body 311, and the third limiting groove 315 is a blind hole. A hinge hole 316 is provided on the other side wall of the opening end of the support body 311. The hinge hole 316 communicates with the third limiting groove 315. The limiting cover 32 is detachably installed in the second limiting groove 314 and the third limiting groove 315.

[0040] It should be noted that, in this embodiment, since the support body 311 has a U-shaped structure and a certain thickness, the second limiting groove 314 penetrates the side wall of the support body 311 along the thickness direction of the support body 311, the third limiting groove 315 is a blind hole provided in a direction perpendicular to the thickness direction of the support body 311, and the hinge hole 316 is also provided in the thickness direction of the support body 311.

[0041] The advantages of adopting the above-mentioned preferred solution are: the support body is a U-shaped structure with the opening facing the door armrest, which is conducive to the fixed installation of the door armrest with the limiting cover; the third limiting groove and hinge hole, together with the elastic cylindrical pin, are conducive to the hinge connection of one end of the limiting cover with the support body; the second limiting groove is an arc-shaped channel that penetrates the side wall of the support body, which is conducive to the locking of the other end of the limiting cover with the support body, thereby realizing the fixation between the support body and the limiting cover.

[0042] Preferred, such as Figure 5 As shown, the limiting cover 32 is a shell structure with an arc-shaped inner wall. The two ends of the limiting cover 32 are respectively fixed with a first limiting protrusion 321 and a second limiting protrusion 322. The first limiting protrusion 321 is rotatably disposed in the third limiting groove 315 by means of an elastic cylindrical pin 33. The elastic cylindrical pin 33 passes through the hinge hole 316 and the first limiting protrusion 321. The second limiting protrusion 322 is engaged with the second limiting groove 314.

[0043] The advantages of adopting the above preferred solution are: the first limiting protrusion is rotatably set in the third limiting groove by an elastic cylindrical pin, which is conducive to hinged connection between one end of the limiting cover and the support body; the second limiting protrusion is engaged with the second limiting groove, which is conducive to fixing the support and the limiting cover, thereby fixing one end of the door armrest in the armrest support assembly.

[0044] Preferred, such as Figure 5 As shown, the support body 311 and the limiting cover 32 are fitted together and fixedly sleeved on one end of the door armrest 4. A second positioning protrusion 317 is fixedly provided at the bottom end of the inner wall of the support body 311. A positioning hole 41 is provided on one side wall of the door armrest 4. The second positioning protrusion 317 is adapted to be inserted into the positioning hole 41.

[0045] It should be noted that since the support body 311 is a U-shaped structure with its opening facing the door armrest 4, "the bottom end of the inner wall of the support body 311" refers to the point on the inner wall of the U-shape that is farthest from the door armrest 4.

[0046] The beneficial effect of adopting the above preferred solution is that the second positioning protrusion is adapted to be inserted into the positioning hole, which is conducive to fixing one end of the door armrest in the support body and the limiting cover while the support body and the limiting cover are fitted together, thus preventing the door armrest from sliding in the support body and the limiting cover.

[0047] Preferred, such as Figure 8 As shown, the inner cover 21 of the armrest adjustment is a shell structure. One end of the inner cover 21 of the armrest adjustment is provided with an adjustment sleeve 211. A first positioning protrusion 212 is provided on the top side wall of the inner cover 21 of the armrest adjustment. The adjustment sleeve 211 is slidably fitted on the other side wall of the door armrest 4.

[0048] It should be noted that in this embodiment, the first positioning protrusion 212 is fixed on the top side wall of the inner armrest adjustment cover 21. The first positioning protrusion 212 is made of rubber or plastic with a certain elasticity. When the outer armrest adjustment cover 22 is assembled from the side, thereby covering the inner armrest adjustment cover 21, the inner wall of the outer armrest adjustment cover 22 presses the first positioning protrusion 212, causing the first positioning protrusion 212 to deform. When the outer armrest adjustment cover 22 is displaced to the point where the limiting hole 222 is above the first positioning protrusion 212, the first positioning protrusion 212 is no longer compressed and returns to its original shape, thereby inserting into the limiting hole 222, so that the outer armrest adjustment cover 22 is fixedly covered on the inner armrest adjustment cover 21. In other embodiments of this utility model, the first positioning protrusion 212 is retractably mounted on the top side wall of the inner armrest adjustment cover 21 by a spring. When the outer armrest adjustment cover 22 is assembled from the side, thereby fitting the outer armrest adjustment cover 22 onto the inner armrest adjustment cover 21, the inner wall of the outer armrest adjustment cover 22 presses against the first positioning protrusion 212, causing the spring to compress and deform. When the outer armrest adjustment cover 22 is displaced to the point where the limiting hole 222 is above the first positioning protrusion 212, the first positioning protrusion 212 is no longer compressed, and the spring returns to its original position, thereby pushing the first positioning protrusion 212 into the limiting hole 222, so that the outer armrest adjustment cover 22 is fixedly fitted onto the inner armrest adjustment cover 21.

[0049] The advantages of adopting the above preferred solution are: the adjusting sleeve can be slidably fitted onto the other side wall of the door armrest, which is beneficial to solve the problem of difficult assembly and adjustment caused by the deviation of the size of the parts by adjusting the fitting position of the adjusting sleeve and the other side wall of the door armrest during the assembly process.

[0050] Preferred, such as Figure 9 As shown, the armrest adjustment outer cover 22 is a shell structure that matches the shape of the armrest adjustment inner cover 21. A slot 221 is provided on one side wall of the armrest adjustment outer cover 22, and a limiting hole 222 is provided on the top side wall of the armrest adjustment outer cover 22. The other side wall of the door armrest 4 is adapted to be disposed in the slot 221, and the first positioning protrusion 212 is adapted to be inserted into the limiting hole 222.

[0051] It should be noted that, in this embodiment, after assembly, the fitting position of the adjusting sleeve 211 and the other side wall of the door armrest 4 is different from the fitting position of the slot 221 and the other side wall of the door armrest 4.

[0052] The advantages of adopting the above preferred solution are: the first positioning protrusion is fitted into the limiting hole, which helps to fix the outer cover of the armrest adjustment onto the inner cover of the armrest adjustment, thereby preventing the inner cover of the armrest adjustment from being exposed and damaged.

[0053] Preferred, such as Figure 9 As shown, both the first handrail end mounting assembly 1 and the second handrail end mounting assembly 2 are fixed to the door glass.

[0054] It should be noted that in this embodiment, the fixing plate 11 and the armrest adjustment inner cover 21 are fixed to the door glass by bolts.

[0055] The advantages of adopting the above preferred solution are: it is beneficial to fix the entire device on the door glass, so that the driver or passenger can open and close the door from the inside of the cockpit.

[0056] The assembly process of this embodiment is described below: like Figures 1 to 9 As shown, firstly, the fixing plate 11 and the armrest adjustment inner cover 21 are fixedly installed on the door glass, and the distance between the fixing plate 11 and the armrest adjustment inner cover 21 is less than the length of the door armrest 4. Then, rotate the support base 31 so that the arc-shaped surface 3121 faces the first limiting groove 14, and make the connecting block 312 enter the first limiting groove 14 from the side of the locking plate 12, and enter the limiting section 142 along the entry channel section 141, as shown. Figure 6 As shown, the support base 31 is then rotated 90 degrees clockwise or counterclockwise so that the line connecting the two arc surfaces 3121 is perpendicular to the entry channel section 141, and the support base 31 is fixed on the first handrail end mounting assembly 1. Next, the other end of the door armrest 4 is moved through the adjusting sleeve 211, and one side wall of the door armrest 4 is placed into the support body 311. The second positioning protrusion 317 is inserted into the positioning hole 41. Then, the first limiting protrusion 321 is inserted into the third limiting groove 315, and the elastic cylindrical pin 33 is inserted into the hinge hole 316, the third limiting groove 315 and the first limiting protrusion 321, so that the first limiting protrusion 321 can rotate around the elastic cylindrical pin 33 in the third limiting groove 315. The second limiting protrusion 322 is engaged with the second limiting groove 314, so that the support 31 and the limiting cover 32 are fixedly connected and fixedly sleeved on one side wall of the door armrest 4. Finally, the outer cover 22 of the armrest adjustment is fitted onto the inner cover 21 of the armrest adjustment from the side. During this process, the slot 221 is engaged on the other side wall of the door armrest 4, and the first positioning protrusion 212 passes through the limiting hole 222 to achieve the fixed fitting of the outer cover 22 of the armrest adjustment and the inner cover 21 of the armrest adjustment, and to cover the inner cover 21 of the armrest adjustment to prevent it from being exposed.
