Description

Technical Field

[0001] This utility model relates to the field of automotive armrest technology, specifically a high-strength foam armrest. Background Technology

[0002] Foamed armrests are common functional components in car interiors, primarily used to enhance driving comfort and convenience. To provide elbow support for passengers, they have evolved into in-car storage boxes, including armrest panels, facilitating conversations, work, and document viewing. The material is mostly polyurethane (PU) foam, which is lightweight, elastic, and has strong shock absorption. Different hardness levels can be achieved by adjusting the formula. Foaming is typically done through molds, where liquid polyurethane is injected into a mold, expands and solidifies through a chemical reaction, forming a porous structure. The process is divided into two types: cold foaming (low-temperature curing, environmentally friendly and energy-saving) and hot foaming (high-temperature rapid molding).

[0003] Chinese patent CN219952507U discloses a polyurethane foam handrail, comprising: a mounting plate and a handrail body. The top of the mounting plate has a groove, and the handrail body is installed through the groove on the top of the mounting plate. A movable spring is installed inside the mounting plate, and a telescopic block is installed on one side of the movable spring. The telescopic block forms a telescopic structure with the mounting plate through the movable spring. Two sets of telescopic blocks are symmetrically installed about the center line of the mounting plate. The outside of the handrail body is covered with an antistatic layer, and the outside of the antistatic layer is covered with a protective sleeve. The antistatic layer is evenly wrapped around the outside of the handrail body, and the protective sleeve is evenly wrapped around the antistatic layer.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent does not allow for quick unlocking and locking of the support frame for stepless angle adjustment, nor does it allow for quick unlocking and locking of the replacement handguard.

[0006] Therefore, those skilled in the art have provided a high-strength foamed handrail to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a high-strength foamed handrail to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A high-strength foam armrest includes a seat, and further includes: an angle adjustment device, a quick replacement device, and a locking device. The angle adjustment device is installed on the left and right sides of the seat, the quick replacement device is installed on the angle adjustment device, and the locking device is installed on the angle adjustment device. The angle adjustment device includes: a support base, a fixed shaft, and a gear. The support base is fixedly installed on the seat, the fixed shaft is fixedly connected to the end of the support base away from the seat, and the gear is fixedly installed on the fixed shaft. The angle adjustment device further includes: a trigger mechanism, which is disposed below the gear.

[0010] Furthermore, a support frame is rotatably connected to the middle side of the fixed shaft, and the middle side of the support frame is hollow.

[0011] Furthermore, the triggering mechanism includes: a rack and a shaped rod, the rack being disposed on the lower side of the gear, the rack and the gear meshing with each other, the shaped rod being hinged to the middle side of the support frame via a rotating shaft, and the front side of the rack being fixedly connected to the rear side of the shaped rod;

[0012] Furthermore, the triggering mechanism also includes an elastic component, which is mounted on the support frame. The elastic component includes a sliding frame and a tension spring. The sliding frame is fixedly mounted on the front side of the irregular rod, the tension spring is fixedly connected to the upper side of the sliding frame, and the other end of the tension spring is fixedly connected to the lower side of the support frame.

[0013] Furthermore, the support frame has sliding grooves on both the front and rear sides, and a slider is slidably connected in the sliding grooves;

[0014] Furthermore, the quick replacement device includes: a replacement handguard, which is fixedly mounted on the slider, and the front and rear ends of the replacement handguard are symmetrical to each other;

[0015] Furthermore, the locking device includes a threaded block and a threaded rod, wherein the threaded block is fixedly installed on the front side of the support frame, and the threaded rod is threadedly connected to the threaded block in the middle.

[0016] Furthermore, a rotating support block is fixedly installed on the support frame, and a rotating rod is rotatably connected to the rotating support block;

[0017] Furthermore, the front side of the rotating rod is fixedly connected to the rear side of the threaded rod;

[0018] Furthermore, a strip-shaped slot is provided on the lower side of the support frame, and a rotating block is provided in the strip-shaped slot. The rotating block is fixedly installed on the rotating rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the rotating of the irregular rod of the trigger mechanism of the angle adjustment device drives the rack to rotate, and the rack disengages from the gear. At this time, the support frame is rotated, and the tilt angle of the support frame can be infinitely adjusted. The sliding frame of the elastic component moves towards the support frame, causing the irregular rod to rotate, which causes the tension spring to undergo elastic deformation. The rotation of the irregular rod drives the rack to rotate, and the rack disengages from the gear. At this time, the support frame is rotated to quickly adjust the angle. After the support frame is adjusted, the sliding frame is released, and the elastically deformed tension spring returns to its original state, pulling the sliding frame back to its initial state. The rotation of the sliding frame back to its initial state drives the rack to rotate, and the rack and gear mesh with each other. At this time, the support frame is quickly locked, which is conducive to quickly unlocking and locking the support frame for infinitely adjustable angle.

[0020] 2. The handguard can be replaced by sliding up and down. Under the constraint of the slider and groove, the handguard can be quickly installed or removed from the support frame. The front and rear ends of the handguard are symmetrical. When the front side of the handguard wears down and the anti-slip effect weakens, the installation direction can be changed. After adjusting the handguard 180 degrees, it can be inserted and installed on the support frame, so that the rear side of the handguard is positioned on the front side of the support frame. The unworn area on the rear side of the handguard provides normal anti-slip effect, which is beneficial for the reuse of the handguard. The rotating block rotates, causing the rotating rod to rotate, which in turn rotates the threaded rod. The threaded rod rotates, causing it to disengage from the slider. At this point, the handguard can be removed by moving it away from the support frame. A new handguard can then be installed, or the handguard can be adjusted 180 degrees and inserted and installed on the support frame again. Rotating the rotating block causes the front side of the threaded rod to press against the slider, locking the slider. This restricts the up and down sliding, facilitating quick unlocking and locking of the handguard. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A high-strength foam armrest includes a seat 1, and further includes: an angle adjustment device 2, a quick replacement device 3, and a locking device 4. The angle adjustment device 2 is installed on the left and right sides of the seat 1, the quick replacement device 3 is installed on the angle adjustment device 2, and the locking device 4 is installed on the angle adjustment device 2. The angle adjustment device 2 includes: a support base 21, a fixed shaft 22, and a gear 23. The support base 21 is fixedly installed on the seat 1, the fixed shaft 22 is fixedly connected to the end of the support base 21 away from the seat 1, and the gear 23 is fixedly installed on the fixed shaft 22. The angle adjustment device 2 also includes: a trigger mechanism, which is disposed below the gear 23.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the angle adjustment device 2 is used to adjust the tilt angle of the handrail, the quick replacement device 3 is used for quick replacement, and the locking device 4 is used to quickly lock the quick replacement device 3.

[0033] like Figure 5 , Figure 6As shown, a support frame 5 is rotatably connected to the middle side of the fixed shaft 22. The middle side of the support frame 5 is hollow. The support base 21 and the fixed shaft 22 are used to restrict the rotation of the support frame 5.

[0034] The triggering mechanism includes a rack 24 and a shaped rod 25. The rack 24 is disposed on the lower side of the gear 23, and the rack 24 and the gear 23 mesh with each other. The shaped rod 25 is hinged to the middle side of the support frame 5 through a rotating shaft, and the front side of the rack 24 is fixedly connected to the rear side of the shaped rod 25.

[0035] like Figure 4 , Figure 5 , Figure 6 As shown, the irregular rod 25 of the trigger mechanism of the angle adjustment device 2 rotates, and the rotation of the irregular rod 25 drives the rack 24 to rotate. The rack 24 disengages from the gear 23. At this time, the support frame 5 is rotated, and the tilt angle of the support frame 5 can be infinitely adjusted.

[0036] The triggering mechanism further includes an elastic component, which is mounted on the support frame 5. The elastic component includes a sliding frame 26 and a tension spring 27. The sliding frame 26 is fixedly mounted on the front side of the irregular rod 25, and the tension spring 27 is fixedly connected to the upper side of the sliding frame 26. The other end of the tension spring 27 is fixedly connected to the lower side of the support frame 5.

[0037] like Figure 4 , Figure 5 , Figure 6 As shown, the sliding frame 26 of the elastic component moves towards the support frame 5, causing the irregular rod 25 to rotate, which causes the tension spring 27 to undergo elastic deformation. The rotation of the irregular rod 25 causes the rack 24 to rotate, and the rack 24 disengages from the gear 23. At this time, the support frame 5 is rotated to quickly adjust the angle. After the support frame 5 is adjusted, the sliding frame 26 is released, and the elastically deformed tension spring 27 returns to its original state, pulling the sliding frame 26 back to its initial state. The sliding frame 26 rotates back to its initial state, causing the rack 24 to rotate. The rack 24 and the gear 23 mesh with each other, and at this time the support frame 5 is quickly locked.

[0038] Example 2: In some embodiments, such as Figures 1-7 In a preferred embodiment of the present invention, the support frame 5 has grooves 31 on both the front and rear sides, and a slider 32 is slidably connected in the grooves 31.

[0039] The quick replacement device 3 includes a replacement hand guard 33, which is fixedly installed on the slider 32, and the front and rear ends of the replacement hand guard 33 are symmetrical to each other.

[0040] like Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the replaceable handguard 33 slides up and down. Under the constraint of the slider 32 and the slide groove 31, the replaceable handguard 33 can be quickly installed or removed from the support frame 5. The front and rear ends of the replaceable handguard 33 are symmetrical. After the front side of the replaceable handguard 33 is worn and the anti-slip effect is weakened, the installation direction can be changed. After adjusting the replaceable handguard 33 by 180 degrees, it can be inserted and installed on the support frame 5, so that the rear side of the replaceable handguard 33 is set on the front side of the support frame 5. The unworn area on the rear side of the replaceable handguard 33 can provide a normal anti-slip effect, which is conducive to the secondary use of the replaceable handguard 33.

[0041] Example 3: In some embodiments, such as Figures 1-7 In a preferred embodiment of the present invention, the locking device 4 includes a threaded block 41 and a threaded rod 42. The threaded block 41 is fixedly installed on the front side of the support frame 5, and the threaded rod 42 is threadedly connected to the threaded block 41.

[0042] like Figure 7 As shown, the threaded rod 42 of the locking device 4 rotates on the threaded block 41, and the front side of the threaded rod 42 is in close contact with the slider 32, so that the slider 32 is locked. At this time, the up and down sliding of the slider 32 is restricted, which is conducive to quickly fixing the slider 32.

[0043] A rotating support block 43 is fixedly installed on the support frame 5, and a rotating rod 44 is rotatably connected to the rotating support block 43.

[0044] The front side of the rotating rod 44 is fixedly connected to the rear side of the threaded rod 42.

[0045] The support frame 5 has a strip-shaped slot 45 on its lower side, and a rotating block 46 is provided in the strip-shaped slot 45. The rotating block 46 is fixedly installed on the rotating rod 44.

[0046] When quickly removing the replacement handguard 33, rotate the rotating block 46. The rotation of the rotating block 46 drives the rotating rod 44 to rotate, which in turn drives the threaded rod 42 to rotate. The rotation of the threaded rod 42 causes it to disengage from the slider 32. At this point, the replacement handguard 33 can be removed by moving it away from the support frame 5. Install a new replacement handguard 33, or adjust the replacement handguard 33 by 180 degrees and then insert it back into the support frame 5. Rotate the rotating block 46. The rotation of the rotating block 46 drives the rotating rod 44 to rotate, which in turn drives the threaded rod 42 to rotate. The front side of the threaded rod 42 is pressed against the slider 32, locking the slider 32 in place. This restricts the up-and-down movement of the slider 32, facilitating quick locking of the replacement handguard 33.

[0047] The support frame 5 can be made of metal, while the replacement hand guard 33 can be made of thermoplastic polyester elastomer. The replacement hand guard 33 provides flexibility and anti-slip properties, while the support frame 5 provides support. The combination of the support frame 5 and the replacement hand guard 33 improves the overall support strength.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
