Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, and in particular to a matching structure of an armrest and a switching component. Background Art

[0002] Nowadays, there are more and more electric vehicles, which gradually replace bicycles. In order to improve the comfort and safety of electric vehicles, bicycles, tricycles and other vehicles, users will choose to set a backrest behind the seat. The backrest can prevent the rear passenger from falling backward due to inertia when starting suddenly or braking suddenly. The backrest is often connected to the armrest at the rear of the vehicle using an adapter. The cross-section of the armrest is an irregular polygon. The armrest is provided with multiple smooth surfaces along the circumference, and a convex ridge line is formed between adjacent smooth surfaces. The adapter usually includes two clips, and the two clips clamp the armrest and the backrest on both sides of the armrest. The upper part of the two clips is connected to the backrest by bolts. A wedge groove is provided below one of the two clips, and a wedge block is provided below the other. The lower part of the two clips is clamped by the wedge groove and the wedge block. Because there are no other connecting parts below the two clips, the connection stability below the two clips determines the connection stability of the backrest. A splicing seam will be formed at the connection below the two clips. The splicing seam of the existing adapter is located at the convex ridge line of the armrest. Electric vehicles will vibrate during use, and passengers will squeeze the backrest. The adapter and the armrest will also generate mutual force due to vibration or squeezing. The contact area between the ridge and the adapter is small, so the pressure here will be greater. The joint seam is located at the ridge, and the squeezing of the ridge seriously affects the connection stability between the two clips. This will require frequent reinstallation of the backrest, which is not only troublesome but also has great safety hazards.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] See also Figures 1 to 8As shown, an embodiment of the present application provides a matching structure of an armrest and an adapter, comprising an armrest 1 and an adapter 2, wherein the armrest 1 is provided with a plurality of smooth surfaces 11 along the circumferential direction, and a convex ridge line 12 is formed between adjacent smooth surfaces 11. The adapter 2 comprises a first clip 21 and a second clip 22, wherein the first clip 21 and the second clip 22 are detachably connected, and a first through groove 201 and a second through groove 202 are formed between the first clip 21 and the second clip 22, wherein the armrest 1 passes through the first through groove 201, and a joint seam 23 is provided between the first clip 21 and the second clip 22, wherein the joint seam 23 is connected to the first through groove 201, and the joint seam 23 is located on the smooth surface 11, and there is a spacing between the joint seam 23 and the convex ridge line 12. The adapter 2 in the matching structure of an armrest and an adapter of the present application connects the armrest 1 and the backrest. When the vehicle vibrates or the passenger squeezes the backrest during driving, the collision or pressure generated between the adapter 2 and the armrest 1 is mainly concentrated on the ridge line 12 and the adapter 2. In the matching structure of the armrest and the adapter of the present application, the joint seam 23 of the first clip 21 and the second clip 22 of the adapter 2 is located on the smooth surface 11 of the armrest 1. The pressure on the joint seam 23 is small, and the gap where the first clip 21 and the second clip 22 are connected is not easy to increase or disengage, which can greatly improve the connection stability between the first clip 21 and the second clip 22, thereby greatly improving the firmness of the backrest installation.

[0045] In some possible implementations, the inner wall of the first clip 21 and the inner wall of the second clip 22 are smoothly transitioned on one side of the joint 23. In this way, there will be no step at the joint 23. If there is a step at the joint 23, the probability of force disengagement will increase, and the step will also cause wear. The smooth transition between the first clip 21 and the second clip 22 at the inner wall joint 23 can avoid these problems.

[0046] Furthermore, the first clip 21 and the second clip 22 have the same thickness near the joint 23, so that the inner wall of the first clip 21 and the inner wall of the second clip 22 can smoothly transition on one side of the joint 23, and the outer wall of the first clip 21 and the outer wall of the second clip 22 can also achieve a smooth transition on the side of the joint 23.

[0047] In some possible implementation schemes, one end of the first clip 21 has a notch groove 211, and one end of the second clip 22 has an insert 221. When the first clip 21 and the second clip 22 are connected, the insert 221 is inserted into the notch groove 211, and the insert 221 is located on the smooth surface 11, and there is a gap between the insert 221 and the convex ridge line 12. One end of the first clip 21 and the second clip 22 is connected to the backrest by bolts, and the other end is inserted into the notch groove 211 by the insert 221. When the bolts connected to the backrest are removed, the insert 221 and the notch groove 211 are easily separated, making the disassembly and assembly of the first clip 21 and the second clip 22 more convenient. However, during use, if the insert 221 is forced to swing, the first clip 21 and the second clip 22 are most likely to be separated. Therefore, the position of the insert 221 is set to fit the smooth surface 11, which can prevent the first clip 21 and the second clip 22 from separating to the greatest extent.

[0048] In some possible implementations, the width of the notch groove 211 gradually increases in the direction from the notch 2111 of the notch groove 211 to the closed end 2112 of the notch groove 211, and the shape of the insert 221 matches the shape of the notch groove 211. When the insert 221 cooperates with the notch groove 211, it moves relatively along the thickness direction to complete the plugging or disassembly, but when the ends of the first clip 21 and the second clip 22 away from the joint seam 23 are stably connected to the backrest, the insert 221 and the notch groove 211 will not move relatively in the thickness direction under the limitation of the armrest 1. The notch groove 211 is set to be a trapezoidal shape with a narrow width at one end of the notch 2111 and a wide width at one end of the groove bottom of the closed end 2112. The inserting piece 221 is also a trapezoidal shape adapted to the notch groove 211. After the inserting piece 221 is inserted into the notch groove 211, it will be limited by the notch groove 211 along the extension direction of the first clamping piece 21. The inserting piece 221 will not be separated from the notch groove 211 in the extension direction of the first clamping piece 21 when subjected to tension. In this way, the connection between the first clamping piece 21 and the second clamping piece 22 is guaranteed to be stable from all directions.

[0049] In some possible implementations, a plug post 212 is provided on the first clip 21, and a positioning hole 13 is provided on the handrail 1. When the adapter 2 is connected to the handrail 1, the plug post 212 is plugged into the positioning hole 13. After the plug post 212 is inserted into the positioning hole 13, the first clip 21 can maintain a stable position relative to the handrail 1. Under the support of the first clip 21, the second clip 22 is also fixed relative to the handrail 1. In this way, the joint 23 will not change position due to vibration, extrusion, etc., and the joint 23 will always be on the smooth surface 11, ensuring that the first clip 21 and the second clip 22 are firmly connected.

[0050] In some possible implementations, the positioning hole 13 is located on one of the convex ridges 12. The handrail 1 at the convex ridge 12 is thicker, and a deeper positioning hole 13 can be set, and the corresponding plug column 212 can also be set to a longer length, which has a stronger positioning stability effect on the first clip 21. In addition, the cross section at the convex ridge 12 is tapered, and the positioning hole 13 is set here. The tapered hole has a guiding effect, so that the plug column 212 is inserted into the positioning hole 13 more smoothly.

[0051] In some possible implementations, the plug post 212 is located on one side of the first clip 21 close to the notch 211. The plug post 212 is close to the notch 211, that is, close to the joint 23. The closer the plug post 212 is to the joint 23, the better the positioning effect at the joint 23 is, and the joint 23 can be prevented from being close to the ridge line 12.

[0052] In some possible embodiments, a first connection hole 213 is provided on a side of the first clip 21 away from the joint 23, and a second connection hole 222 is provided on a side of the second clip 22 away from the joint 23. A fastener is provided through the first connection hole 213 and the second connection hole 222 to connect and fix the first clip 21 and the second clip 22. After the insert 221 is inserted into the notch 211, the fastener passes through the second connection hole 222 and the first connection hole 213 in sequence to be fastened to the backrest. Preferably, the fastener may be a bolt, the nut of the bolt is limited on the side of the second connection hole 222 away from the backrest, and the stud passes through the second connection hole 222 and the first connection hole 213 in sequence to be threadedly connected to the backrest. The use of threaded connection facilitates disassembly and assembly and later replacement and maintenance.

[0053] In some possible implementations, the first connection hole 213 is a round hole, and the second connection hole 222 is a long hole. When the fastener fixes the first clamp 21 and the second clamp 22, the long hole can provide a certain range of adjustment effect, so that it is easier to fine-tune the alignment of the first clamp 21 and the second clamp 22 during installation, so that the installation can be more accurate. In addition, there is no need to process the adapter 2 with very high precision, and there is no need to use high-precision processing equipment, thereby reducing the processing cost.

[0054] In some possible embodiments, the first clip 21 has a first strip segment 214 and a second strip segment 215, and the second clip 22 has a third strip segment 223 and a fourth strip segment 224. When the first clip 21 and the second clip 22 are connected, a first through slot 201 is formed between the first strip segment 214 and the third strip segment 223, and a second through slot 202 is formed between the second strip segment 215 and the fourth strip segment 224. The first strip segment 214 and the third strip segment 223 cover the armrest 1, the second strip segment 215 and the fourth strip segment 224 cover the connecting pipe on the backrest, and the second strip segment 215 and the fourth strip segment 224 are connected to the backrest through fasteners. The segmented covering has better covering effect and adaptability, and thus can also improve the connection stability. Among them, there is a smooth transition between the first strip segment 214 and the second strip segment 215, and a smooth transition between the third strip segment 223 and the fourth strip segment 224, without sharp corners, and is not easy to wear or break.

[0055] Furthermore, the third segment 223 has a straight segment 2231 and inclined segments 2232 located at both ends of the straight segment 2231, the two inclined segments 2232 are far away from one end of the straight segment 2231, and a smooth surface 11 of the handrail 1 is located between the two inclined segments 2232. The handrail 1 has multiple smooth surfaces 11, one of which is located between the two inclined segments 2232, and the two smooth surfaces 11 adjacent to the smooth surface 11 correspond to the positions of the two inclined segments 2232, so that the limiting effect between the adapter and the handrail 1 is better, preventing the second clip 22 from rotating relative to the handrail 1, and the connection stability is higher. And the third segment is set in this way, the third segment is more closely attached to the handrail 1, which can ensure more convenient and accurate assembly.
