Description

Technical Field

[0001] This utility model relates to the field of automotive armrests, specifically to an adjustable armrest frame and armrest. Background Technology

[0002] Car armrests are very common in cars, such as the armrests on the rear seats. The armrests rotate on the rear seats and are normally located in the armrest groove on the seat back, so they do not affect people sitting in the seat. When the armrest is needed, it can be rotated out of the armrest groove.

[0003] The handrail has an internal frame that supports it, preventing significant deformation. The frame also serves as a mounting base for mechanical structures such as locking mechanisms.

[0004] Because the armrest frame is located inside the armrest and supports it, different armrest lengths require different length frames. Currently, armrest frames are designed as a single piece, requiring different processing equipment or redesigning and adjusting the length parameters when producing frames of different lengths. This results in high manufacturing costs and cumbersome operations. Furthermore, with the rapid pace of automotive model updates, if there is an overproduction of armrest frames to meet a production demand for a particular length, these frames cannot be used for other lengths, leading to low versatility and eventual waste. Utility Model Content

[0005] The present invention aims to provide an adjustable handrail frame and handrail to solve the current problem of fixed handrail frame length. It can change the length of the handrail frame according to the manufacturing requirements of handrails of different lengths, thereby improving the versatility of the handrail frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable handrail frame, comprising a first frame and a second frame, wherein the first frame is provided with a first sliding end and the second frame is provided with a second sliding end;

[0007] The adjustable handrail frame has a sliding state and a fixed state; in the sliding state, the first sliding end and the second sliding end slide together; in the fixed state, the first sliding end and the second sliding end are fixed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a handrail, including an adjustable handrail frame as described in this patent.

[0009] The principle and advantages of this patented solution are as follows: In this patented solution, the handrail frame is divided into two parts, the first frame and the second frame. In this way, the handrail frame is no longer a one-piece design, but is composed of two separate parts, the first frame and the second frame, connected together. Thus, the first frame and the second frame can be manufactured separately, and then the first frame and the second frame are connected and fixed together to form the handrail frame in this patent.

[0010] Since the handrail frame is composed of a first frame and a second frame connected together, and the first sliding end and the second sliding end slide together, the length of the handrail frame can be adjusted by combining the first frame and the second frame and sliding the first sliding end relative to each other. After the length of the handrail frame is adjusted, the first sliding end and the second sliding end are fixed, thereby fixing the first frame and the second frame together, and then the handrail frame can be applied to the handrail.

[0011] In summary, compared to existing technologies, this patented solution does not use a single integrated design for the handrail frame. Instead, it consists of two separate parts: a first frame and a second frame. The length of the handrail frame is adjusted by the relative sliding of the first and second sliding ends. The first and second frames are then fixed together to complete the handrail frame manufacturing process. By considering the different sliding conditions of the first and second sliding ends, handrail frames of varying lengths can be manufactured, solving the current problem of fixed handrail frame lengths. The first and second frames can be connected to form handrail frames of different lengths according to the actual handrail length, greatly improving their versatility. During manufacturing, only the first and second frames of fixed sizes need to be produced, eliminating the need for adjustments to production equipment or multiple design adjustments to the handrail frame length parameters. After mass production, the first and second frames can be connected and fixed to form handrail frames of different lengths, resulting in greater utilization of both the first and second frames, reducing the probability of discarding them and minimizing material waste.

[0012] Preferably, as an improvement, the second sliding end is provided with a plurality of horizontally arranged second through holes, and the first sliding end is provided with at least one first through hole;

[0013] In the fixed state, a connector is inserted through the first through hole and the second through hole.

[0014] Therefore, during the relative sliding process of the first sliding end and the second sliding end, the second through hole and the different first through holes are opposite each other. Then, the connector passes through the first through hole and the second through hole, thereby fixing the first sliding end and the second sliding end. After the length of the handrail frame is adjusted, the length of the handrail frame is fixed and no longer changes.

[0015] Preferably, as an improvement, the connector is a bolt.

[0016] Preferably, as an improvement, the first sliding end and the second sliding end are welded together in the fixed state. Thus, after the first sliding end and the second sliding end slide relative to each other, they are fixed together by welding, resulting in a high connection strength and a more stable connection between the first frame and the second frame.

[0017] Preferably, as an improvement, the top and bottom of the first sliding end are both fixedly provided with a first bending portion, the two first bending portions are arranged opposite to each other, and the second sliding end is located between the two first bending portions.

[0018] Therefore, with the two first bends facing each other and the second sliding end located between them, the two first bends clamp the second sliding end. Under this clamping action, the relative sliding of the second and first sliding ends is more stable, and the first and second sliding ends will not shift in the width direction. At the same time, the top and bottom of the first sliding end are fixedly provided with first bends, which enhances the strength of the first sliding end compared to not having first bends.

[0019] Preferably, as an improvement, the top and bottom of the second sliding end are both fixedly provided with second bends, and the two second bends are opposite to each other; the two second bends are located between the two first bends, and the second bends and the first bends are in contact with each other.

[0020] Therefore, the second bend is located at the top and bottom of the second sliding end, which enhances the strength of the second sliding end compared to when it does not have a second bend. Simultaneously, the first and second bends fit together, allowing for welding of both the first and second sliding ends, thus increasing the welding area and significantly improving the strength of the first and second frames after welding.

[0021] Preferably, as an improvement, there are two first frames, which are arranged opposite to each other; a first bend on one first frame and a first bend on the other first frame are connected by a transverse connector.

[0022] The transverse connector is used to connect the two first frames. The first bend also serves to connect with the transverse connector. By setting the first bend, the connection between the first frame and the transverse connector has a large contact area, ensuring the connection strength between the transverse connector and the first frame.

[0023] Preferably, as an improvement, the wall thickness of both the first sliding end and the second sliding end is 1-3 mm.

[0024] Preferably, as an improvement, the width of the first sliding end is 20-30mm. Attached Figure Description

[0025] Figure 1 This is a 3D view of the handrail frame.

[0026] Figure 2 This is a three-dimensional view of the first skeleton.

[0027] Figure 3 This is a three-dimensional view of the second skeleton. Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method:

[0029] The reference numerals in the accompanying drawings include: second frame 1, first frame 2, second through hole 3, first through hole 4, second sliding end 5, second bend 6, first sliding end 7, transverse connector 8, and first bend 9.

[0030] Example 1

[0031] The basics are as follows: Figures 1-3 As shown: An adjustable handrail frame includes a first frame 2 and a second frame 1. The first frame 2 is provided with a first sliding end 7, and the second frame 1 is provided with a second sliding end 5.

[0032] The adjustable handrail frame has a sliding state and a fixed state. In the sliding state, the first sliding end 7 and the second sliding end 5 are not fixed, and the first sliding end 7 and the second sliding end 5 slide together. In the fixed state, the first sliding end 7 and the second sliding end 5 are fixed, and the first sliding end 7 and the second sliding end 5 can no longer slide laterally relative to each other. In this embodiment, the wall thickness of both the first sliding end 7 and the second sliding end 5 is 1-3mm. The width of the first sliding end 7 ( Figure 2 The width of the vertical direction is 20-30mm, and the width of the second sliding end 5 is ( Figure 3 The length of the first sliding end 7 (in the left-right direction in the figure) is 20-30mm. The length of the second sliding end 5 (in the left-right direction in the figure) is 45-70mm. The specific values ​​can be set according to the actual situation.

[0033] Combination Figure 2 As shown, in this embodiment, there are two first frames 2, which are arranged opposite each other. The tops of the two first frames 2 are connected (e.g., welded) by a transverse connector 8, which is specifically plate-shaped. The transverse connector 8 connects the two first frames 2 together. Combined with... Figure 3 As shown, in this embodiment, there are also two second skeletons 1. The two second skeletons 1 are arranged opposite each other, and a connecting plate is connected (e.g., welded) between the right ends of the two second skeletons 1. The two second skeletons 1 are connected together through the connecting plate.

[0034] The first sliding end 7 is provided with a first through hole 4, and the second sliding end 5 is provided with multiple second through holes 3. In this embodiment, the number of second through holes 3 is illustrated by two, but in other embodiments, it can be set to three, four, five, or other different numbers. The spacing between adjacent second through holes 3 can be set according to actual needs, for example, 10-20mm. In the figure, the number of first through holes 4 is set to one, but in other embodiments, the number of first through holes 4 can also be set to multiple. The diameters of the first through holes 4 and the second through holes 3 can be set according to actual conditions, for example, 4-10mm.

[0035] Therefore, the handrail frame in this embodiment is not designed as a single piece, but rather as two separate parts: a first frame 2 and a second frame 1. These two separate parts are manufactured separately. Figure 1 As shown, the first frame 2 and the second frame 1 are first assembled together, with the first sliding end 7 and the second sliding end 5 fitting together. The second sliding end 5 is located on the inner side of the first sliding end 7 (the side opposite to the two first frames 2 is the inner side). At this time, the first frame 2 and the second frame 1 are not fixed and are in a sliding state. The first sliding end 7 and the second sliding end 5 can slide relative to each other. The length of the handrail frame can be changed according to different handrail lengths. Since there are two second through holes 3 in this embodiment, the handrail frame in this embodiment has two lengths. When the second through hole 3 near the end of the second sliding end 5 is opposite to the first through hole 4, the overlap between the first sliding end 7 and the second sliding end 5 is small, and the handrail frame is longer. When the second through hole 3 far from the end of the second sliding end 5 is opposite to the first through hole 4, the overlap between the first sliding end 7 and the second sliding end 5 is large, and the handrail frame is shorter.

[0036] Therefore, according to the required handrail length, before fixing the length of the handrail frame, the handrail frame can be adjusted to different lengths by sliding the first frame 2 and the second frame 1 relative to each other. After the handrail frame length is adjusted, the first sliding end 7 and the second sliding end 5 are initially fixed by connecting parts (such as bolts) passing through the first through hole 4 and the second through hole 3. At this time, the handrail frame becomes fixed, and the first sliding end 7 and the second sliding end 5 will no longer slide relative to each other, thus fixing the length of the handrail frame. Then, the first sliding end 7 and the second sliding end 5 are welded together to further fix the first sliding end 7 and the second sliding end 5 together, making the connection between the first frame 2 and the second frame 1 more firm and stable.

[0037] Finally, the handrail frame is applied inside the handrail of the appropriate length to provide support.

[0038] Example 2

[0039] This embodiment is a further optimization based on embodiment 1. In this embodiment, the top and bottom of the first sliding end 7 are integrally fixed with a first bending part 9, the two first bending parts 9 are arranged opposite to each other, and the second sliding end 5 is located between the two first bending parts 9.

[0040] The top and bottom of the second sliding end 5 are both integrally fixed with a second bending portion 6, and the two second bending portions 6 are opposite to each other; the two second bending portions 6 are located between the two first bending portions 9, and the second bending portions 6 and the first bending portions 9 are in contact. In this embodiment, the bending directions of the first bending portions 9 and the second bending portions 6 are the same, both bending towards the inside of the armrest frame. Of course, in other embodiments, the bending direction can also be towards the outside of the armrest frame.

[0041] The reason why the first bending part 9 and the second bending part 6 are provided in this embodiment is that, compared with not providing the first bending part 9 and the second bending part 6, the first bending part 9 and the second bending part 6 can be welded in a fixed state, thereby increasing the contact area of ​​the welding of the first frame 2 and the second frame 1 and improving the welding strength of the handrail frame.

[0042] In addition, the transverse connector 8 can also be welded to the first bend 9 on the top of the two first frames 2. The contact area between the end of the transverse connector 8 and the first frame 2 is large, and the transverse connector 8 is welded to the first frame 2 more firmly and stably.

[0043] In summary, the handrail frame in the above embodiments is not integrally fixed during manufacturing. Instead, it is composed of two separate parts: a first frame 2 and a second frame 1. The first frame 2 and the second frame 1 are assembled and connected together. The length of the handrail frame is adjusted by the relative sliding of the first frame 2 and the second frame 1. After the length of the handrail frame is adjusted, the first frame 2 and the second frame 1 are then fixed. In this way, the length of each handrail frame can be adjusted according to the needs of handrails of different lengths at the beginning of manufacturing. After adjustment, the first frame 2 and the second frame 1 are fixed and used for the corresponding handrails. The first frame 2 and the second frame 1 can be used to manufacture handrail frames of different lengths, improving their versatility. The first frame 2 and the second frame 1 can be mass-produced initially. Subsequently, according to the production needs of handrail frames of different lengths, the overlap of the first sliding end 7 and the second sliding end 5 can be adjusted to connect the first frame 2 and the second frame 1.

[0044] In the above embodiments, "first" and "second" are descriptive distinctions made for ease of description and do not substantially limit the specific structure or scope of protection. Figure 1The skeleton on the right side can be called the first skeleton 2, and the skeleton on the left side can be called the second skeleton 1; the through hole on the first skeleton 2 can also be called the second through hole 3, and the through hole on the second skeleton 1 can be called the first through hole 4.

[0045] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
