Description

Technical Field

[0001] This utility model relates to the field of automotive armrest technology, and in particular to an anti-detachment installation structure for armrests. Background Technology

[0002] Many types of cars (such as MPVs) have side armrests on the sides of the seats for passengers to support their arms.

[0003] In existing car seats with armrests, the main installation methods are bolt fixing and spring-loaded locking. Bolt fixing requires covering the armrest's exterior, affecting its aesthetics and uniformity, and also makes disassembly inconvenient. Spring-loaded locking is prone to improper installation, with the spring not engaging properly in the spline groove, posing a risk of detachment. Furthermore, when the armrest is pulled outwards from a non-removable position by external force (such as from the passenger side), the spring can deform, reducing the disassembly force at the normal removal position. This makes the armrest easily detached during use, leading to recalls due to detachment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a handrail anti-detachment installation structure that can prevent the handrail from loosening and is easy to assemble and disassemble.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a handrail anti-detachment installation structure, including:

[0006] The mounting shaft has a first end and a second end, the first end being disposed on a car seat, and the second end being available for mounting an armrest. The mounting shaft is provided with a first slot.

[0007] The handrail is equipped with a retaining spring. When the handrail is installed on the mounting shaft, the retaining spring is engaged in the first retaining groove, and the second end of the mounting shaft extends into the handrail.

[0008] A limiting member is disposed at the second end of the mounting shaft and located in the handrail, the limiting member preventing the handrail from detaching from the mounting shaft.

[0009] Furthermore, the second end of the mounting shaft is provided with a second slot, and the limiting member is engaged in the second slot.

[0010] Furthermore, the second slot is configured as an annular groove circumferentially disposed along the second end of the mounting shaft;

[0011] The limiting component is configured as a C-shaped buckle, which is detachably snapped into the annular groove.

[0012] Furthermore, the C-shaped buckle has an opening, and two fastening arms are respectively arranged on both sides of the opening;

[0013] The outer diameter of the second end of the mounting shaft at the annular groove is greater than the width of the opening;

[0014] After the opening of the C-shaped buckle is aligned with the annular groove, the C-shaped buckle can be squeezed into the annular groove, and both of the buckling arms are engaged in the annular groove.

[0015] Furthermore, each of the two fastening arms is provided with a guide slope at its end, and the guide slope gradually slopes outward from the inside to the outside.

[0016] Furthermore, the armrest sleeve is mounted on the mounting shaft;

[0017] After the limiting member disengages from the second end of the mounting shaft, external force can cause the retaining spring to disengage from the first retaining groove, thereby removing the handrail from the mounting shaft.

[0018] Furthermore, the handrail includes a lower handrail assembly and an upper handrail cover, wherein the upper handrail cover is detachably and fixedly connected to the lower handrail assembly;

[0019] When the armrest cover is opened from the lower armrest assembly, the second end of the mounting shaft and the limiting member can be exposed.

[0020] Furthermore, the handrail is provided with a handrail frame, the retaining spring is located on one side of the handrail frame, the limiting member is located on the other side of the handrail frame, and the limiting member moves against the handrail frame.

[0021] Furthermore, the first slot is arranged in a ring shape, and the mounting shaft is perpendicular to the handrail.

[0022] Furthermore, the mounting shaft is provided with a spline groove, and the spline groove is located between the first slot and the second slot.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In this invention, a first slot is provided on the mounting shaft, and a retaining spring is provided in the handrail. After the handrail is installed on the mounting shaft, the retaining spring engages with the first slot. A limiting member is provided at the second end of the mounting shaft to prevent the handrail from detaching from the mounting shaft. That is, the handrail is engaged with the mounting shaft by the retaining spring, and the limiting member at the second end of the mounting shaft effectively prevents the handrail from detaching from the mounting shaft.

[0025] In this invention, a second slot is provided at the second end of the mounting shaft, and a C-shaped buckle is configured as the limiting member, which is detachably engaged in the second slot. When it is necessary to remove the handrail from the mounting shaft, simply disengage the C-shaped buckle from the second slot to remove the handrail, making disassembly convenient.

[0026] In this invention, the width of the opening on the C-shaped buckle is smaller than the outer diameter of the mounting shaft at the annular groove. After the opening is aligned with the annular groove, the C-shaped buckle can be squeezed into the annular groove, ensuring that the C-shaped buckle is easy to snap into and that the snap into a secure connection.

[0027] In this invention, the handrail includes a lower handrail assembly and an upper handrail cover. The upper handrail cover is detachably and fixedly connected to the lower handrail assembly. After the upper handrail cover is removed from the lower handrail assembly, the limiting member and the second end are exposed. During assembly, the lower handrail assembly is first installed on the mounting shaft, and then the limiting member is snapped into the second slot. This allows the operator to easily observe whether the retaining spring and the limiting member are properly installed, ensuring reliable assembly. Attached Figure Description

[0044] like Figures 1-5 As shown, a handrail anti-detachment installation structure in this embodiment mainly includes:

[0045] Mounting shaft 1 has a first end 11 and a second end 12, which are arranged opposite to each other. The first end 11 is disposed on the car seat, and the second end 12 is for mounting armrest 2. The mounting shaft 1 is provided with a first slot 13. Specifically, the first end 11 has a fixing plate welded to it. The fixing plate has multiple through holes, and bolts or screws pass through the fixing plate to fix it to the frame of the car seat, ensuring the structural stability of the mounting shaft 1. The first slot 13 is annular, which facilitates processing.

[0046] The armrest 2 is equipped with a retaining spring 20. Specifically, the armrest 2 can be adjusted up and down on the car seat. An adjuster 24 is also provided in the armrest 2, and the retaining spring 20 is disposed in the adjuster 24. When the armrest 2 is installed on the mounting shaft 1, the retaining spring 20 is engaged in the first retaining groove 13, and the second end 12 of the mounting shaft 1 extends into the armrest 2. After the armrest 2 is installed on the mounting shaft 1, the mounting shaft 1 is perpendicular to the armrest 2, meaning the armrest 2 can be assembled onto the mounting shaft 1 by side insertion.

[0047] A limiting member 3 is disposed at the second end 12 of the mounting shaft 1 and is located in the handrail 2. The limiting member 3 can prevent the handrail 2 from detaching from the mounting shaft 1.

[0048] In practical use, this embodiment has a first slot 13 on the mounting shaft 1 and a retaining spring 20 in the handrail 2. After the handrail 2 is installed on the mounting shaft 1, the retaining spring 20 is engaged in the first slot 13. A limiting member 3 is provided at the second end 12 of the mounting shaft 1 to prevent the handrail 2 from detaching from the mounting shaft 1. That is, the handrail 2 is engaged with the mounting shaft 1 by the retaining spring 20, and the limiting member 3 at the second end 12 of the mounting shaft 1 effectively prevents the handrail 2 from detaching from the mounting shaft 1.

[0049] In this embodiment, after the handrail 2 is fixed to the mounting shaft 1 by the snap ring 20 and the first snap groove 13, the handrail 2 is further restricted from detaching from the mounting shaft 1 by the limiting member 3. The limiting member 3 can be implemented by bolts, screws and other types of components.

[0050] Preferably, such as Figures 5-7 As shown, in this embodiment, the second end 12 of the mounting shaft 1 is provided with a second slot 120, and the limiting member 3 is engaged in the second slot 120. The second slot 120 ensures that the limiting member 3 is engaged reliably and is not easily displaced.

[0051] Furthermore, the second slot 120 is configured as an annular groove circumferentially arranged along the second end 12 of the mounting shaft 1. The annular groove is easy to process, for example, it can be machined on a lathe. In this embodiment, the limiting member 3 is configured as a C-shaped buckle. The C-shaped buckle is C-shaped and can be a standard purchased part, without special manufacturing, thus reducing costs. The C-shaped buckle is detachably engaged in the annular groove, and the C-shaped buckle prevents the handrail 2 from detaching from the mounting shaft 1.

[0052] In this embodiment, the handrail 2 is sleeved on the mounting shaft 1. In actual use, after the limiting member 3 is disengaged from the second end 12 of the mounting shaft 1, external force can cause the snap ring 20 to disengage from the first slot 13, so as to remove the handrail 2 from the mounting shaft 1.

[0053] In this embodiment, a second slot 120 is provided at the second end 12 of the mounting shaft 1, and the limiting member 3 is configured as a C-shaped buckle, which is detachably engaged in the second slot 120. When it is necessary to remove the handrail 2 from the mounting shaft 1, the handrail 2 can be removed simply by disengaging the C-shaped buckle from the second slot 120, making disassembly convenient.

[0054] Furthermore, the C-shaped buckle has an opening 30, and two fastening arms 31 are respectively arranged on both sides of the opening 30. The outer diameter of the second end 12 of the mounting shaft 1 at the annular groove is larger than the width of the opening 30. When the opening 30 of the C-shaped buckle is aligned with the annular groove, the C-shaped buckle can be squeezed into the annular groove using a tool. Both fastening arms 31 are engaged in the annular groove, that is, the two fastening arms 31 of the C-shaped buckle can undergo a certain elastic deformation to ensure that the two fastening arms 31 can be smoothly engaged in the annular groove, and after engagement, reliable engagement can be guaranteed.

[0055] Furthermore, each of the ends of the two fastening arms 31 is provided with a guide slope 310. The guide slope 310 gradually slopes outward from the inside to the outside. The setting of the two guide slopes 310 makes it convenient for the fastening arms 31 to be engaged in the annular groove, which can reduce the difficulty of assembling the C-shaped buckle.

[0056] In actual use, the width of the opening 30 on the C-shaped buckle in this embodiment is smaller than the outer diameter of the mounting shaft 1 at the annular groove. After the opening 30 is aligned with the annular groove, the C-shaped buckle can be squeezed into the annular groove, ensuring that the C-shaped buckle is easy to snap into and that the snap into a secure connection.

[0057] In this embodiment, the mounting shaft 1 is provided with a spline groove 14, which is used to connect with the angle adjuster 24 in the armrest 2. The spline groove 14 is located between the first slot 13 and the second slot 120 to ensure a reliable connection between the armrest 2 and the mounting shaft 1.

[0058] like Figures 1-4 As shown, the handrail 2 in this embodiment includes a lower handrail assembly 21 and an upper handrail cover 22, wherein the upper handrail cover 22 is detachably and fixedly connected to the lower handrail assembly 21. When the upper handrail cover 22 is opened from the lower handrail assembly 21, the second end 12 of the mounting shaft 1 and the limiting member 3 can be exposed.

[0059] In actual use and assembly, the handrail 2 of this embodiment includes a lower handrail assembly 21 and an upper handrail cover 22. The upper handrail cover 22 is detachably and fixedly connected to the lower handrail assembly 21. After the upper handrail cover 22 is removed from the lower handrail assembly 21, the limiting member 3 and the second end 12 can be exposed. During assembly, the lower handrail assembly 21 is first installed on the mounting shaft 1, and then the limiting member 3 is snapped into the second slot 120, which makes it convenient for the operator to observe whether the retaining spring 20 and the limiting member 3 are installed in place, ensuring reliable assembly.

[0060] Furthermore, the handrail 2 is equipped with a handrail frame 23, the retaining spring 20 is located on one side of the handrail frame 23, and the limiting member 3 is located on the other side of the handrail frame 23. The limiting member 3 moves against the handrail frame 23. When the handrail 2 is pulled outward by an external force (such as a passenger's arm or leg pushing against the handrail 2) in a non-detached position, the limiting member 3 is subjected to force, which can protect the retaining spring 20 from plastic deformation to a certain extent, ensuring that the retaining spring 20 is not prone to fatigue and the structure is not prone to failure.

[0061] In the actual installation process, first, the handrail frame 23 and the lower handrail assembly 21 are installed onto the mounting shaft 1. The spline groove 14 is detached from the angle adjuster 24 in the handrail 2, and the retaining spring 20 at the angle adjuster 24 engages with the first retaining groove 13 on the mounting shaft 1. Then, using a C-shaped clip installation tool, the limiting member 3 (i.e., the C-shaped buckle) is snapped into the second retaining groove 120 at the second end 12 of the mounting shaft 1. At this point, the C-shaped buckle can be visually inspected to ensure it is properly installed, and the retaining spring 20 can be determined to be properly engaged with the first retaining groove 13. Finally, the upper handrail cover 22 is fixedly installed onto the lower handrail assembly 21, completing the installation.

[0062] In this design, the handrail 2 is engaged with the mounting shaft 1 by a snap ring 20, and by setting a limiting member 3 at the second end 12 of the mounting shaft 1, the handrail 2 can be effectively prevented from detaching from the mounting shaft 1.
