Description

Technical Field

[0001] This utility model belongs to the field of electric luggage, and in particular relates to an electric luggage control lever assembly. Background Technology

[0002] As the main control component of electric luggage, the control lever is crucial. Electric luggage typically operates in two modes: riding mode and traditional luggage mode (pull-pull operation). For example, the electric luggage proposed in CN215851653U incorporates a brake lever and a speed control lever in its steering mechanism. This requires wiring inside the steering lever and across the lever and the luggage body. Frequent extension and retraction of the steering lever and steering movements lead to wear and tear on the internal wiring harness, which is difficult to detect. Furthermore, it requires two hands to operate, making it complex and costly to manufacture and maintain. Additionally, a dual-lever structure is needed to separately control riding and push-pull modes, further complicating operation and significantly encroaching on the interior space. Utility Model Content

[0003] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0004] An electric luggage handle assembly, comprising:

[0005] joystick;

[0006] The control switch is independently located on one side of the joystick;

[0007] The speed control mechanism and the braking mechanism are located on both sides of the control lever. When the control lever is moved away from the braking mechanism, the speed control mechanism is activated to adjust the speed, and when it is moved away from the speed control mechanism, the braking mechanism is activated to brake.

[0008] The switching component is located on one side of the control lever and its position relative to the control lever is adjustable. It is used to open and close the control switch and to constrain the speed regulation structure and braking structure to move away from the control lever.

[0009] In the control assembly, the speed regulation structure includes a constraint body and a Hall electromagnetic rocker distributed on the front side of the control lever;

[0010] The braking structure includes a second constraint body and a second micro switch located on the rear side of the control lever;

[0011] One end of constraint body one and constraint body two are rotatably arranged, and the other end is provided with a closed body. The two are connected by an elastic body near the control lever. The closed body and the elastic body are located on the left and right sides of the control lever, respectively.

[0012] The micro switch and the Hall effect electromagnetic rocker correspond to the positions of the closed bodies, respectively.

[0013] In the control assembly, the closed body gradually deviates from the switching element along the length direction of the constraint body;

[0014] Both constraint body one and constraint body two have a waist structure in the middle, which is located on the outside of the control lever.

[0015] In the control assembly, the switching element is provided with a central bar and two closing bars. The two closing bars are distributed on the outer sides of constraint body one and constraint body two, and the central bar is distributed in the middle of the two closing bars.

[0016] In the control assembly, a mounting plate is provided on the outer side of the control lever, and the mounting plate is provided with mounting holes. The mounting holes are oblong holes, and the control lever is located in the mounting holes.

[0017] In the control assembly, the mounting plate is provided with a recessed groove, and a through groove is provided in the recessed groove. An operating handle is slidably fitted in the through groove, and the operating handle is integrally connected to the switching component.

[0018] The mounting plate is equipped with guide bodies and limit bodies. The guide bodies are arranged along the length of the constraint members, and the limit bodies are arranged at the end position of the switching members.

[0019] In the control assembly, the switching element is provided with an extension body, and the extension body and the control switch are positioned correspondingly. When the switching element is in the final position, the extension body triggers the control switch.

[0020] In the control assembly, one end of the control lever is equipped with an operating part, and the other end is equipped with a connecting part;

[0021] A connecting rod is installed on the connecting part, and the connecting rod is connected to the steering wheel. There are two sets of steering wheels located on both sides of the bottom of the box.

[0022] In the control assembly, the connecting part includes a connecting plate one fixed to the bottom of the control lever, and the connecting rod includes a connecting plate two mounted on the steering wheel. The connecting plate two and the connecting plate one are connected by a connecting plate three. The connecting plate two is distributed at both ends of the connecting plate three, and the connecting plate one is mounted in the middle of the connecting plate three.

[0023] In the control assembly, the bottom of the connecting part is independently provided with a T-shaped sleeve and a support plate. The support plate is provided with a through hole. The lower end of the T-shaped sleeve is inserted into the through hole. The connecting bolt passes through the through hole and the T-shaped sleeve and the connecting part to connect and fix them. The lower end of the T-shaped sleeve is a small end and its outer diameter is 0.1-0.5mm smaller than the inner diameter of the through hole. The length of the small end is 0.1-0.5mm larger than the thickness of the support plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This invention features a speed-regulating structure and a braking structure on the outer side of the control lever. A switching mechanism is used to lock and release the middle section of the control lever. Upon release, a control switch is triggered, connecting the power supply and electric wheels to the circuit, activating the riding mode. Pushing the control lever forward deflects it approximately 4mm, during which a Hall effect electromagnetic rocker is activated to control forward movement. In an emergency, the lever can be pulled back to brake using the body's natural instinct. To switch to push-pull mode, the switching mechanism is reversed, attaching the speed-regulating and braking structures to the front and rear sides of the control lever. The control lever can rotate or remain stationary. Rotation is suitable for pushing the box vertically from front to back, while stationary operation is suitable for pulling the box at an angle from back to front, preventing the box from tipping over during rapid pulling. A single lever control allows for both modes, minimizing space encroachment within the box. Attached Figure Description

[0040] Example 1

[0041] like Figure 1 , 2 As shown, an electric luggage handle assembly includes:

[0042] Joystick 10;

[0043] The control switch 40 is independently located on one side of the control lever 10;

[0044] The speed control structure and the braking structure are located on both sides of the control lever 10. When the control lever 10 is moved away from the braking structure, the speed control structure is activated to adjust the speed, and when it is moved away from the speed control structure, the braking structure is activated to brake.

[0045] The switching element 50 is located on one side of the control lever 10 and its position relative to the control lever 10 is adjustable. It is used to open and close the control switch 40 and constrain the speed regulation structure and the braking structure to move away from the control lever.

[0046] In practical implementation, moving the switching element 50 away from the control lever 10 triggers the control switch 40, supplying power to the system. This activates the riding mode, releasing the constraints of the speed control and braking mechanisms. Pushing the control lever 10 activates the speed control mechanism, which controls the rotation of the electric wheel for forward movement; pulling the control lever 10 activates the braking mechanism, which brakes the electric wheel. Moving the switching element 50 closer to the control lever 10 cuts off power to the system, activating the push-pull mode. The speed control and braking mechanisms are constrained, resulting in a pulling operation state, thus enabling effective operation in both modes.

[0047] Example 2

[0048] In the aforementioned joystick assembly, such as Figure 3 As shown, the speed control structure includes a constraint body 21 and a Hall electromagnetic rocker 42 distributed on the front side of the control lever 10;

[0049] The braking structure includes a constraint body 22 and a micro switch 41 distributed on the rear side of the control lever 10;

[0050] One end of constraint body 1 21 and constraint body 22 are rotatably arranged, and the other end is provided with a closed body 24. The two are connected by an elastic body 23 near the position of the control lever 10. The closed body 24 and the elastic body 23 are located on the left and right sides of the control lever 10, respectively.

[0051] Microswitch 41 and Hall effect electromagnetic rocker 42 correspond to the positions of the corresponding closed bodies 24.

[0052] The closed body 24 gradually deviates downward from the switching component 50 along the length direction of the constraint body;

[0053] Both constraint body 1 21 and constraint body 22 are provided with waist structure 25 in the middle. The waist structure 25 is arranged on the outside of the control lever 10. When constrained, the waist structure 25 can be used to strictly constrain the control lever 10 in the front and back. After strict constraint, it can be ensured that the control lever 10 is in the center position and the handle and steering wheel 30 are flush.

[0054] like Figure 4 As shown, the switching component 50 is provided with a central strip 51 and two closing strips 52. The two closing strips 52 are distributed on the outer sides of the first constraint body 21 and the second constraint body 22, and the central strip 51 is distributed in the middle of the two closing strips 52. Both the switching component 50 and the constraint component 20 are made of wear-resistant material.

[0055] like Figure 2 As shown, the control switch 40 is a micro switch, and the switching element 50 is provided with an epitaxial body 53. The epitaxial body 53 and the control switch 40 are in the same position. When the switching element 50 is in the final position, the epitaxial body 53 triggers the control switch 40.

[0056] When the operating handle 72 moves to the left to the position of the limiting body 74, the extension body 53 will trigger the control switch 40, and the circuit of the electric wheel will be closed. In this embodiment, the forward and backward control lever 10 is used to control the forward and emergency braking actions.

[0057] When constraint body 1 21 moves forward, constraint body 1 21 drives the closed body 24, triggering the Hall electromagnetic rocker 42. The maximum forward distance is about 4mm. The speed is controlled by triggering the Hall electromagnetic rocker 42. When the forward force of the control lever 10 is released, constraint body 1 21 will automatically reset under the action of the elastic body 23. At the same time, the opening degree of the Hall electromagnetic rocker 42 decreases, reducing the speed and naturally slowing down. In case of emergency, the body reacts instinctively by pulling the control lever 10 backward. Constraint body 2 22 moves backward and triggers the micro switch 41 via the closed body 24, applying emergency braking to the electric wheel. The maximum backward distance is about 2mm. When pulling is required, the operating handle 72 is moved to the right, and the closing bar 52 re-constrains the closed body 24. The speed control circuit and brake control circuit here are existing control circuit forms.

[0058] When the switch 50 is operated to the left, the two closing bars 52 will open the two closed bodies 24, releasing the constraints on the first constraint body 21 and the second constraint body 22. After the constraints are released, the closed bodies 24 and the closing bars 52 are now vertically misaligned, and the closed bodies 24 can only move away from the middle bar 51 relative to the middle bar 51.

[0059] When the operation is turned to the right, the closing bar 52 will return to the outside of the closing body 24, with the vertical height consistent. The closing body 24 cannot move back and forth relative to the middle bar 51, and the control lever 10 is constrained. Both the switching component 50 and the constraint component 20 are made of wear-resistant materials.

[0060] like Figure 10 As shown, the mounting plate 70 is provided with a recessed groove 71, and a through groove is provided in the recessed groove 71. An operating handle 72 is slidably fitted in the through groove, and the operating handle 72 is integrally connected to the switching component 50.

[0061] like Figure 2 As shown, a guide body 73 and a limiting body 74 are installed on the mounting plate 70. The guide body 73 is arranged along the length direction of the constraint member 20, and the limiting body 74 is arranged at the end position of the switching member 50.

[0062] Example 3

[0063] In the aforementioned joystick assembly, such as Figures 5 to 9 As shown, one end of the control lever 10 is equipped with an operating part, and the other end is equipped with a connecting part;

[0064] A connecting rod is installed on the connecting part, and the connecting rod is connected to the steering wheel 30.

[0065] The connecting part includes a connecting plate 11 fixed to the bottom of the control lever 10, and a connecting rod includes a connecting plate 12 mounted on the steering wheel 30. The connecting plate 12 and the connecting plate 11 are connected by a connecting plate 13. The connecting plate 12 is distributed at both ends of the connecting plate 13, and the connecting plate 11 is mounted in the middle of the connecting plate 13.

[0066] To accommodate the slight forward and backward movement required by the joystick 10, such as Figures 6 to 9 As shown, the bottom of the connecting part is independently provided with a T-shaped sleeve 14 and a support plate 15. The support plate 15 is installed on the reinforcement structure at the bottom corner of the inner side of the box. The support plate 15 is provided with a through hole 16. The lower end of the T-shaped sleeve 14 is inserted into the through hole 16. The connecting bolt passes through the through hole 16 and the T-shaped sleeve 14 and is connected and fixed to the connecting part. The lower end of the T-shaped sleeve 14 is a small end and its outer diameter is 0.1-0.5mm smaller than the inner diameter of the through hole 16.

[0067] The steering wheel 30 can only turn relative to the housing structure and cannot move forward or backward slightly. Therefore, after the connecting part is installed using connecting bolts, a small gap is reserved between the T-shaped sleeve 14 and the through hole 16. After installation, the T-shaped sleeve 14 can deflect slightly relative to the through hole 16 (0.1-0.5mm forward or backward). The connecting plate assembly itself can absorb this deformation without fatigue, so as to cope with the forward and backward displacement of the control lever 10. When turning, the connecting plate 11 drives the connecting plate 2 12 to rotate synchronously through the connecting plate 3 13, thereby controlling the steering of the steering wheel 30.

[0068] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
