Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a bicycle control device. Background Art

[0002] Current road bicycles tend to adopt a "fully internal routing" overall design, where oil pipes, cables, etc. are all hidden inside the vehicle. The highly integrated fully internal routing system makes the road bike look more concise as a whole. However, replacing the oil pipes and shift cables has become complicated.

[0003] Some electronic bicycle control devices (also known as bicycle shifters) have been disclosed in the prior art. The patent document CN104973297B discloses a bicycle control device, which includes a grippable housing that can be mounted on the handlebar of a bicycle; a power source connected to a bicycle control component; a shift lever assembly movably connected to the housing; an electrical switch; and a controller in communication with the electrical switch, the controller being powered by the power source and capable of generating a signal in response to an input of the electrical switch to change the gear of an electromechanical shifting device. The patent document CN107303934B discloses a bicycle control device, which includes a housing, an operating member, a hydraulic unit fixedly and non-removably mounted in the housing, a wireless communicator, an electrical switch, a communication controller, and a power source, wherein the wireless communicator is provided at an additional operating member of the operating member, and the communication controller and the power source are provided in an end portion of the housing, and these electronic functional modules are respectively arranged at different positions of the bicycle control device.

[0004] Most of these commercially available bicycle control device products are designed such that when a failure occurs, the entire bicycle control device needs to be replaced. For example, in cases where the brake lever breaks due to a fall, the shift lever button malfunctions, the circuit board fails, the brake components are damaged or there is an oil leak, etc., the entire bicycle control device needs to be replaced. In addition, when replacing the entire bicycle control device, the tubing connector pipeline connected to the oil cylinder inside the bicycle control device cannot be reused, and the tubing needs to be cut to a certain length to form a new tubing joint to connect to the bicycle control device. However, the fully internal routing system is extremely sensitive to the length of the tubing. If the length of the tubing reserved during the initial installation of the bicycle is insufficient, the entire tubing line needs to be replaced, otherwise the too short tubing will affect the turning of the handlebar. Once the tubing of the internal routing system needs to be replaced, it takes a mechanic several hours of work to complete, which not only increases the maintenance pressure on the mechanic but also increases the repair cost for the user.

[0005] Therefore, it is necessary to design a new bicycle control device that can directly replace a faulty component without replacing the entire bicycle control device. Summary of the Invention

[0039] Next, the technical solutions of the embodiments will be clearly and completely described in conjunction with the accompanying drawings of the present application. Those skilled in the art can understand that the embodiments described in the specification are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments described in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0040] In the description of this patent specification, the orientation or positional relationship indicated by "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "longitudinal", "lateral", "center", "vertical", "horizontal", "length", "width", "thickness", "clockwise", "counterclockwise", etc. is based on the bicycle control device as shown in Figure 1 These orientation and positional relationships are only for the convenience of describing the embodiments involved in the technical innovation of the present utility model and should not be construed as limiting the protection scope of the claims. In addition, those skilled in the art can understand that the terms "first" and "second" used in this specification to describe various components are only for distinguishing one component from another and have no meaning of sequence, and the corresponding components should not be limited by these terms.

[0041] In the present utility model, the bicycle can be any type of bicycle, such as a mountain bike, a road bike, etc. As Figure 1 described, the bicycle control device 10 proposed in the embodiment of the present utility model is fixed to the handlebar 14 by a clamp 12. The clamp 12 includes a U-shaped clamp, such as a clamping collar that wraps around the handlebar for positioning. The bicycle control device 10 includes a housing 20, a brake lever component 30 partially disposed in the housing 20, an electronic module 40 disposed on the brake lever component 30, and an oil cylinder assembly 50. The oil cylinder assembly 50 is operably connected to a bicycle hydraulic brake, and one end of a fully internal-wired oil pipe (also called a hydraulic hose) is in fluid communication with the oil cylinder outlet of the oil cylinder assembly 50, and the other end is connected to the bicycle hydraulic brake. The electronic module 40 is operably connected to the electric shift devices (such as a front derailleur and a rear derailleur) of the bicycle in a wireless communication manner.

[0042] The housing 20 can be made of any suitable material, such as metal, plastic, and / or composite materials. The housing 20 includes a first end 22 close to the handlebar 14 and a second end 24 away from the handlebar 14. The housing 20 further includes a grip portion 26 located between the first end 22 and the second end 24, and the interior of the grip portion 26 is a hollow cavity. An opening adapted to the upper end of the brake lever component 30 is provided below the second end 24 of the housing 20, and the opening is in communication with the hollow cavity. In the embodiment shown in the specification drawings, the housing 20 is integrally formed in the shape of a grip to provide support for the palm when the user is riding a bicycle.

[0043] As Figures 2 - 5As shown, the brake lever component 30 includes an upper end portion 31. When the bicycle control device 10 is assembled, the upper end portion 31 of the brake lever component 30 is received within the opening of the second end portion 24 of the housing 20. A pivot through-hole 36 is formed in the upper end portion 31 of the brake lever component 30, and a pivot 32 laterally passes through the housing 20 and the pivot through-hole 36 in the upper end portion 31 of the brake lever component 30, thereby attaching the brake lever component 30 to the housing 20. In this way, the brake lever component 30 is pivotally or movably attached to the housing 20, and thus the brake lever component 30 can pivot about the pivot 32 in a direction closer to or away from the handlebar 14. The direction closer to or away from the handlebar 14 is the circumferential direction defined by the axis of the pivot 32. The brake lever component 30 can be made of any suitable material, such as metal, plastic, and / or composite material.

[0044] The brake lever component 30 includes an operation portion 34 extending away from the housing 20 from the upper end portion 31 of the brake lever component 30. At least a part of the side of the operation portion 34 facing the handlebar 14 is formed with a U-shaped groove 35. As Figure 3 shown, the operation portion is an operation lever. A part of the electronic module 40 is fixed within the groove. The brake lever component 30 further includes a piston driving portion 38 provided above the operation portion 34. The piston driving portion 38 is also received within the opening of the second end portion 24 of the housing 20 and is located between the upper end portion 31 and the operation portion 34 of the brake lever component.

[0045] The bicycle control device further includes an oil cylinder assembly 50 for braking. The first end portion 22 of the housing 20 is also provided with an opening communicating with the hollow inner cavity. The hollow inner cavity of the housing 20 is integrally formed to be adapted to the outer shape of the oil cylinder assembly 50 with a certain redundant space, so that the oil cylinder assembly 50 can be detachably assembled into the housing 20. When it is necessary to replace the housing 20 or the oil cylinder assembly 50 and the user assembles a new housing 20 or oil cylinder assembly 50, the oil cylinder assembly 50 can be movably pushed into the hollow inner cavity of the housing 20 from the opening of the first end portion 22 of the housing 20. At this time, the oil cylinder assembly 50 located within the housing 20 is closer to the first end portion 22 of the housing 20 than the pivot 30.

[0046] In other embodiments, the housing 20 may also be composed of two or three parts of the housing, that is, a housing that is not integrally formed. For example, the housing 20 may be composed of a first housing located above and a second housing located below. The first housing is detachably mounted and connected to the second housing. An inner cavity is formed inside the second housing, and there is an opening above the inner cavity. When the first housing is placed on the second housing, it can cover the opening above the inner cavity, so that the first and second housings are combined to form a hollow inner cavity. The oil cylinder assembly 50 is assembled in the hollow inner cavity. If it is necessary to replace the oil cylinder assembly, the first housing can be opened, the original oil cylinder assembly can be taken out from the inner cavity of the second housing, and then the new oil cylinder assembly can be placed into the inner cavity of the second housing. Similarly, if it is necessary to replace the housing, the first housing can be opened, the oil cylinder assembly can be taken out from the inner cavity of the second housing, and then the oil cylinder assembly can be placed into the inner cavity of the new second housing. The hollow inner cavity formed by the combination of the first housing and the second housing can be molded to fit the outer shape of the oil cylinder assembly and leave a certain redundant space, so that the oil cylinder assembly can be better detachably assembled into the housing.

[0047] The oil cylinder assembly 50 includes an oil cylinder and a piston movably disposed in the oil cylinder. The piston includes a piston rod 52 extending outside the oil cylinder. The oil cylinder is provided with an outlet, and the hydraulic oil pipe is connected to the outlet of the oil cylinder through a pipe joint. The internal structure of the oil cylinder assembly 50 is prior art and will not be described in detail here. The oil cylinder assembly 50 includes a first end close to the handlebar 14 and a second end far from the handlebar 14. The piston rod 52 is disposed at the second end of the oil cylinder assembly 50. The oil cylinder outlet is disposed at the first end of the oil cylinder assembly 50. In the embodiment shown in the accompanying drawings of the specification, the piston rod 52 is a piston push rod. The piston driving portion 38 of the brake lever member 30 is provided as a contact portion. When the oil cylinder assembly 50 is assembled in the housing 20, the piston rod 52 contacts the piston driving portion 38 of the brake handle 30. When the user performs an operation of pivoting the brake lever member 30 in the direction of the handlebar 14 through the operation portion 34, the piston driving portion 38 pushes the piston rod 52 and thus drives the piston to linearly move inside the oil cylinder, so that the hydraulic oil in the oil cylinder flows from the opening of the oil cylinder into the hydraulic oil pipe.

[0048] As Figure 3 shown, the oil cylinder assembly 50 further includes two fixing members 54 (such as machine screws or pins, etc.) and two mounting and dismounting through holes 56 located at the second end. During installation, the two fixing members 54 respectively pass through the mounting and dismounting through holes 56 and the mounting through holes 28 formed at the corresponding positions on the housing 20 in the vertical direction, so as to fix the oil cylinder assembly 50 inside the housing 20. In Figure 3 the embodiment shown, the housing above the hollow inner cavity becomes the upper part of the housing, and the housing below the hollow inner cavity is called the lower part of the housing.

[0049] In one embodiment, two mounting through-holes may be provided at appropriate positions on the upper part of the housing, so that the fixing member 54 sequentially passes through the mounting through-hole of the housing 20 and the mounting and dismounting through-hole 56 of the oil cylinder assembly 50 from top to bottom, thereby fixing the oil cylinder assembly 54 in the hollow inner cavity of the housing 20. During disassembly, a screw tool is inserted into the mounting through-hole of the housing 20 to remove the fixing member 54.

[0050] In another embodiment, as Figure 2 shown, two mounting through-holes 28 may be provided at appropriate positions on the lower part of the housing 20. During installation, the fixing member 54 enters from the mounting through-hole 28 of the housing 20, then passes through the mounting and dismounting through-hole 56 of the oil cylinder assembly 50 and then penetrates into the upper part of the housing 20 (as Figure 4 shown), thereby fixing the oil cylinder assembly 54 in the hollow inner cavity of the housing 20. During disassembly, a screw tool such as an Allen key can pass through the mounting through-hole 28 to reach the position of the oil cylinder assembly 50 to remove the fixing member 54. This embodiment is adopted when the housing is integrally injection-molded from plastic or other similar composite materials, because the lower part of the housing 20 is relatively thin, and relatively speaking, the fixing member 54 has better firmness in fixedly connecting the oil cylinder assembly 50 to the upper part of the housing 20.

[0051] When the oil cylinder assembly 50 is disassembled, the housing 20 can be pushed along the Figure 2 arrow direction shown, and the oil cylinder assembly 50 can be separated from the opening of the first end 22 of the housing 20. Figure 2 shows the state where the oil cylinder assembly 50 of the bicycle control device is separated from the housing 20.

[0052] The first end of the oil cylinder assembly 50 includes two recessed parts provided on both sides, namely the first recessed part 57 and the second recessed part 58. A through-hole penetrating from one side to the other side is formed between the first recessed part 57 and the second recessed part 58. The U-shaped clamp includes an annular part adapted to the handlebar 14 and two ends extending along the annular part. The two ends of the U-shaped clamp are respectively provided with a first protrusion 122 and a second protrusion 124 for cooperating with the first recessed part 57 and the second recessed part 58 of the oil cylinder assembly 50. Through-holes are respectively formed on the first protrusion 122 and the second protrusion 124, so that the fastening bolt 16 can horizontally pass through the through-hole between the first recessed part 57 and the second recessed part 58 and the through-holes on the first protrusion 122 and the second protrusion 124 of the U-shaped clamp 12 to fixedly connect the U-shaped clamp 12 to the first end of the oil cylinder assembly 50. The first end of the oil cylinder assembly 50 is also provided with an arc-shaped end face 59 adapted to the handlebar 14, which can increase the firmness of fixing the oil cylinder assembly 50 to the handlebar 14. In the embodiment of the present utility model, the bicycle control device 10 is fixed to the handlebar 14 by means of the first end of the oil cylinder assembly 50 and the clamp 12.

[0053] On the side of the first end portion 22 of the housing 20, an installation notch 224 exposing the fastening bolt 16 is formed so that a user can mount the bicycle control device 10 onto the handlebar 14 or dismount it from the handlebar 14. In addition, an arc-shaped notch 222 adapted to the handlebar 14 is also formed in the first end portion 22. As Figure 1 shown, when the bicycle control device 10 is fixed to the handlebar 14, the housing 20 having the arc-shaped notch 222 can better adapt to the handlebar 14.

[0054] In a preferred embodiment of the present utility model, since the oil cylinder assembly 50 is arranged to slidably extend out or slide into the first end portion 22 of the housing 20, to ensure the rigidity and durability of the oil cylinder assembly 50, the oil cylinder assembly 50 is made of a metal material. The piston rod 52 is also made of a metal material. Correspondingly, Figure 3 and Figure 5 as shown in, the piston driving portion 38 of the brake lever component includes a driving base and a metal rod 39 mounted on the driving base. A metal cylinder (such as a bearing) movable in the length direction of the metal rod 39 is assembled on the metal rod 39, and the side surface of the metal cylinder is in direct contact with the piston rod 52.

[0055] As Figure 3 and Figure 6 and Figure 7 shown, the electronic module 40 includes a key touch plate 42, a printed circuit board module (PCB board module) 44, and an electronic module base 46 arranged from front to back. The printed circuit board module 44 can be fixedly assembled to the electronic module base 46, and thus the printed circuit board module 44 is located between the key touch plate 42 and the electronic module base 46. Both surfaces of the printed circuit board module 44 have circuit wiring designs. In this application, the front surface of the printed circuit board module 44 is called the first surface 441, and the rear surface is called the second surface 447. The first surface 441 includes a first button 442 and a second button 443 arranged at both ends, a microcontroller 445, a radio frequency antenna module 446, etc. The microcontroller 445 is electrically connected to the radio frequency antenna module 446. A switch circuit connected to the first button and the second button is also arranged on the first surface 441, and the switch circuit is electrically connected to the microcontroller 445. Figure 8 shows a schematic diagram of the electrical connection relationship of some electronic components in the electronic module.

[0056] The electronic module 40 further includes a power module. The power module includes a battery holder and a battery 45 mounted in the battery holder. As Figure 7 shown, a metal elastic sheet 448 is arranged on the second surface 447. Both ends of the metal elastic sheet 448 are fixedly connected to the second surface 447, and the middle portion of the metal elastic sheet 448 protrudes from the second surface 447 by a certain height, thus forming a battery holder. As Figure 3 and Figure 7As shown, the battery 45 includes a button battery, which can be installed in the space defined by the metal spring piece 448 and the second surface 447. Among them, the metal spring piece 448 is connected to the positive pole of the battery 45, and the copper-clad area on the second surface 447 is connected to the negative pole of the battery 45. The battery 45 is used to supply power to the microcontroller 445. In addition, according to the design requirements, the battery 45 can also supply power to other components, chips or circuits in the printed circuit board module 44.

[0057] The button touch plate 42 arranged adjacent to the printed circuit board module 44 includes a first pressing area and a second pressing area. A first protruding portion 422 is provided in the middle part of the button touch plate 42, and a second protruding portion 462 is provided in the middle part of the electronic module base 46. The button touch plate 42 and the electronic module base 46 are pivotally connected by a pivot (not shown) passing through the first protruding portion 422 and the second protruding portion 462, and the button touch plate 42 can rotate around the pivot. On the surface of the button touch plate 42 facing the printed circuit board module 44, there are an upper button contact portion and a lower button contact portion (not shown) with a certain height. When the user presses the first pressing area of the button touch plate 42, the upper button contact portion of the button touch plate 42 can directly contact and press the first button 442; when the user presses the second pressing area of the button touch plate 42, the lower button contact portion of the button touch plate 42 can directly contact and press the second button 443.

[0058] Pressing the first button 442 closes the switch circuit, thereby triggering the switch circuit to generate a first electrical signal to the microcontroller 445. Pressing the second button 443 closes the switch circuit, thereby triggering the switch circuit to generate a second electrical signal to the microcontroller 445. For example, the switch circuit can be electrically connected to different pins of the microcontroller 445. The switch circuit sends the generated first electrical signal to one pin of the microcontroller 445 and the generated second electrical signal to another pin of the microcontroller 445. After the microcontroller 445 generates corresponding operation control instructions according to the first or second electrical signal, it is sent to the electric shift device through the radio frequency antenna module 446. Specifically, the microcontroller 445 can generate a data packet with the first or second button / key information and send it to the electric shift device. The microcontroller 45 can also receive signals from the electric shift device for corresponding operation processing.

[0059] A battery installation opening 464 is provided on the side of the electronic module base 46. The electronic module 40 further includes a side cover 48 for covering the side of the electronic module base 46. After the printed circuit board module 44 is assembled to the electronic module base 46, if the battery 45 needs to be replaced, the side cover 48 can be opened, the battery can be taken out from the battery installation opening 464, and then the battery 45 can be installed into the area defined by the metal spring piece 448 from the battery installation opening 464.

[0060] The bicycle control device according to the embodiment of the present utility model adopts the thinking of modular design. Figure 9 The structural schematic diagram showing the detachable connection between the electronic module and the brake handle component of the bicycle control device is shown. Figure 10 The structural schematic diagram showing the detachable connection between the brake handle component and the housing of the bicycle control device is shown. As Figure 2 , Figure 4 , Figure 9 and Figure 10 shown, the housing 20, the brake handle component 30, the electronic module 40, and the oil cylinder assembly 50 are each an independent module or component. If any one of these independent modules fails, only the faulty module needs to be replaced accordingly, without replacing the entire bicycle control device. In most cases, once a traditional bicycle control device fails, the entire bicycle control device needs to be replaced, which not only increases the cost of a new bicycle control device but also increases the maintenance cost of the full internal wire routing.

[0061] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
