New description: [New technical field] The new type relates to brake handles, especially for brake handles for electric bicycles. The handles of the brakes can be mounted on the handlebars of electric bicycles driven by motors. . [Prior Art] The brake handle of the bicycle of φ is connected to the brake device by a connecting member such as a cable, a connecting rod, and a hydraulic pipe, and is used to brake the brake device. The brake handle generally includes a mounting bracket attached to the handlebar and a handle member swingably mounted to the mounting bracket. The mounting bracket ‘ has a mounting portion attached to the handlebar and a bracket portion coupled to the mounting portion. The mounting portion, for example, can be clamped to the handlebar to form a cylindrical shape. The handle member is rotatably attached to the bracket portion. In such a brake handle, a conventional configuration is provided in which a plurality of operation switches are provided in the mounting portion of the handlebar (for example, refer to Patent Document 1). The conventional brake handle is provided with an operation switch for shifting the shifting device to the mounting portion of the brake handle. A display portion for displaying an operation result, a vehicle speed, or the like is provided in the bracket portion. Therefore, the operation switch is disposed at a position close to the thumb of the hand for operating the handle member, so that frequent shifting operations are easily performed. [Prior Art Document] [Patent Document] [Patent Document 1] -3- M419723 曰本licon No. 3 487840 [New Content] [New problem to be solved] The above-described conventional structure is attached to a handlebar The mounting portion is configured with a plurality of switches. Therefore, it is easy to operate the operation switch with a finger. However, the mounting portion is usually formed in a cylindrical shape, so if a plurality of operation switches are arranged, the size of the one-to-one operation switches becomes small and may be difficult to operate. In particular, in the case of electric self-driving such as a power-assisted bicycle used by a general person, it is difficult to perform a driving force assisting operation when the operation switch is too small. The problem of the present invention is to facilitate the operation: an operation switch for assisting operation of the driving force disposed in the brake handle of the electric assist bicycle. [Means for Solving the Problem] The first new type of brake handle for an electric bicycle is a brake handle for an electric bicycle that is assisted by a motor. The brake handle has: a mounting bracket, a handle member, and an operation switch. The mounting bracket has a mounting portion that can be attached to a handlebar of a bicycle, and a bracket portion that is coupled to the mounting portion. The handle member is swingably mounted to the bracket portion. A plurality of operation switches, which are disposed in the bracket portion, are switches for driving force assist operation. The brake handle is not a mounting portion that is generally formed into a tubular shape toward the handlebar, and a plurality of operation switches for operating the electric bicycle are disposed in the bracket portion. Therefore, when the arrangement area is larger than that of the mounting portion, a plurality of large operation switches can be arranged. Here, the plurality of -4- M419723 operation switches for driving force assist operation are disposed in the bracket portion instead of the mounting portion, thereby increasing the size of the plurality of operation switches. Therefore, it is easy to operate: the operation switch for assisting the operation of the driving force disposed in the brake handle of the electric bicycle. A brake handle for an electric bicycle according to a second aspect of the invention is the handle of the first aspect, wherein the bracket portion has a mounting plane that intersects with the swing axis of the handle member, and the plurality of operation switches are push button switches disposed on the mounting plane. In this case, since the mounting plane is disposed to intersect the swing axis, it is easy to operate the push button switch with the index finger or the middle finger of the hand holding the handle member. In the third type of brake handle for an electric bicycle, the handle of the first or second type is described, and the plurality of operation switches are switches for driving the auxiliary mode of the electric bicycle. In this case, since the driving force assist mode can be switched with a plurality of operation switches, the driving force assist mode can be easily switched. [New Effect] According to the present invention, by arranging a plurality of operation switches in the bracket portion instead of being disposed in the mounting portion, the size of the plurality of operation switches can be increased. Therefore, it is easy to operate: an operation switch for assisting the driving force arrangement in the brake handle of the electric bicycle. [Embodiment] In the first embodiment, the bicycle according to an embodiment of the present invention is assisted by the motor 10 The drive of the electric assisted bicycle.

A display device 18 is fixed beside the central portion of the handlebar. • The display device 18 has a liquid crystal display screen 18a. The liquid crystal display screen 18a can be switched, for example, to an auxiliary screen for displaying a screen of the assist mode and a regenerative brake screen for displaying a screen of the regenerative braking mode. The left and right sides of the bicycle here are usually the right side of the bicycle when viewed from the rear and the left side of the left side. <Structure of the brake handle> The right brake handle 16f is connected to the front brake device 10 8f by the front brake cable 25 f. The left brake handle i6r is connected to the M419723 rear brake device l〇8r by the rear brake cable 25r. The front brake cable 25f and the rear brake cable 25γ have a cylindrical outer casing 25a and a inner wire 25b that is movably attached to the outer casing 25a. The right brake handle 16f and the left brake handle 16r are respectively provided. There are: a mounting bracket 30 that is detachably attached to the handlebar 115, and a handle member 31 that is swingably attached to the mounting bracket 30 about the swing shaft 40. <Structure of Mounting Bracket> As shown in Figs. 2, 3, and 4, the mounting bracket 30 has a mounting portion 41 that is attached to the handlebar 115 at the upper portion of Fig. 2, The bracket portion 42 and the outer locking portion 43 are coupled to the mounting portion 41. As shown in FIG. 3, the mounting portion 41 is a tubular member having a slit 41a. By fastening the fixing bolt 45 disposed to intersect the slit 41a, the mounting bracket 30 can be fixed to the handlebar. 1 15. The bracket portion 42 is swingably attached to the handle member 31 by the swing shaft 40, and has a mounting surface 42a formed, for example, in a plane on the front surface thereof. On the mounting surface 42a of the right hand grip 16f, a light switch 44a as a plurality of operation switches and a screen change switch 44b are arranged side by side. The screen switching switch 44b is a switch for switching the liquid crystal display screen 18a of the display device 18 to the auxiliary screen and the regenerative braking screen. The light switch 44a and the screen change switch 44b are two diamond-shaped push button switches of a size in this embodiment. Each time the light switch 44a is pressed, the headlight 1 16 is turned on/off. Each time the screen changeover switch 44b is pressed, the liquid crystal display screen 18a of the display device 18 is switched to the auxiliary screen and the regenerative brake screen M419723. The mounting surface 42a of the left brake handle 16r is disposed as a plurality of operation switches. The first mode switching switch 44c, the second mode switching switch 44d, and the power switch 44e. The first mode changeover switch 44c and the second mode changeover switch 44d are two diamond-shaped push button switches of a large size, arranged side by side. The first mode changeover switch 44c is a switch that sequentially selects a plurality of regenerative braking modes or a plurality of auxiliary modes in the first direction. The second mode switching φ switch 44d is a switch for sequentially selecting a plurality of regenerative braking modes or a plurality of auxiliary modes in a second direction opposite to the first direction. The power switch 44e is a circular push button switch disposed below the second mode changeover switch 44d, and is a switch that turns on/off the power of the auxiliary device 12. Each time the first mode changeover switch 44c is pressed, the cursor for selecting the regenerative braking mode or the assist mode is sequentially moved in the first direction. Select this mode when the movement stops. The second mode changeover switch 44d similarly moves the cursor in the second direction in order. The power switch 44e turns on/off the power of the auxiliary φ device 12 every time the pressing operation is performed. The light switch 44a is substantially the same size as the first mode changeover switch 44c. The screen changeover switch Mb and the second mode changeover switch 44d are substantially the same size. The light switch 44a and the first mode changeover switch 44c are similarly shaped to be slightly smaller. Thereby, the light switch 44a and the screen changeover switch 44b, and the first mode changeover switch 44c and the second mode changeover switch 44d can be distinguished from the light switch 44a, the screen changeover switch 44b, the first mode changeover switch 44c, and The outer peripheral portion of the second mode changeover switch 44 (1) is surrounded by an edge portion 42b that protrudes from the mounting -9 - M419723 surface 42a and is recessed from each of the switches 44a to 44d. Thereby, each switch 44 is easily prevented. The operation of the inside of the bracket portion 42. Next, the internal structure of the bracket portion 16f and the left brake lever 16r have the same structure in a mirror image relationship. Therefore, in the following description, the left side is explained. The description of the structure of the brake handle 16r is omitted, and the description of the structure of the right brake handle 16f is omitted. As shown in Fig. 3, inside the bracket portion 42, a handle for mounting the handle member 31 so as to be swingable is formed. The space 42 c. The handle mounting space 42c is shaped to allow the handle member 31 to swing from an initial position shown by a solid line in FIG. 3 to a maximum swing position shown by a two-dot chain line. The swing shaft 40 is disposed on the upper portion of the handle mounting space 42 c. The left brake handle 16r further includes an initial position adjustment unit 50 disposed inside the bracket portion 42 and a movement position detecting unit 53. The initial position adjustment unit 50 is an initial position for adjusting the handle member 31. The initial position adjusting portion 50 includes an adjusting bolt 51 and a bolt hole 52 formed in the bracket portion 42. The adjusting bolt 51 is, for example, a ball stud. 52. The handle mounting member 42 is formed to be contactable from the outer side surface of the bracket portion 42 toward the handle mounting space 42 c above the outer locking portion 43. The adjusting bolt 51 is screwed into the bolt hole 5 in the direction in which the bolt is fastened. 2. The initial position of the handle member 31 is swung toward the maximum swing position side, whereby the handle member 31 is easily grasped even by a small hand. The moving position detecting portion 53 is for detecting the slave handle member 3. The swinging stroke is calculated from the initial position of 1. The moving position detecting unit 53 is disposed above the initial position adjusting unit 50 of the bracket unit 42. The moving position detecting unit 53 faces the −10 M419723 toward the handle member 31. The magnet 54 is embedded. The moving position detecting unit 53 has, for example, a linear Hall element 55 that can measure the distance from the magnet 54 in accordance with the analog current of the magnitude of the magnetic field of the magnet 54. Thus, it can be derived from linear Huo. When the output of the element 55 is detected, the distance from the magnet 54 is detected, and the swinging stroke of the handle member 31 can be detected. Therefore, even if the initial position of the handle member 31 is adjusted by the initial position adjusting unit 50, From the output of the linear Hall element 55 to define the adjusted initial position, the stroke from the initial position can be reliably detected φ. The braking force of the motor 1 时 in the regenerative braking mode is controlled by the detected stroke of the handle member 31. At the boundary portion between the bracket portion 42 and the mounting portion 41, a circuit wiring 60 for electrically connecting the switches 44a to 44e and the linear Hall element 55 to the motor 10 and the electric assist device 12 is taken out. The outer locking portion 43 is screwed into a mounting screw portion 42d formed at an end portion of the bracket portion 42 opposite to the protruding side of the handle member 31. The outer locking portion 43 has a locking portion main body 47 that is screwed into the mounting screw portion 42d, and a locking nut 48 that prevents the locking portion main body 47 from rotating. The locking portion main body 47 can lock the outer casing 25a of the rear brake cable 25r, and can change the locking position in the longitudinal direction. The gap of the rear brake device 108r can be adjusted by changing the locking position. <Configuration of Handle Member> The handle member 3 1 is swingably mounted between the initial position shown by the solid line in Fig. 3 and the maximum swing position indicated by the two-dot chain line. Bracket portion 42. The handle member 31 has a bearing portion 57 in which an -11 - M419723 swing shaft 40 is attached at one end and an inner locking portion 56 is attached at the other end, and is bent from the other end of the bearing portion 57 to be bent toward the handlebar 11 5 Brake operation portion 58 extending outside. At the other end of the bearing portion 57, an L-shaped lever ratio changing groove 57a capable of changing the lever ratio of the handle member 31 to two types is formed. In the lever ratio changing groove 57a, the embedding member 59 is detachably embedded, and the inner locking portion is swung rather than moved toward one of the both end portions of the lever change groove 51a. The inner locking portion 56 is rotatably coupled to the other end of the bearing portion 57 to change one end portion of the groove 57a. The drum portion 25c fixed to the end of the inner cable 25b is locked to the inner locking portion 56. The handle member 31 is biased toward the initial position by a biasing member (not shown). In the left brake handle 16r and the right brake handle 16f configured in this manner, a plurality of operation switches, that is, switches 44a to 44e, are disposed on the mounting surface 42a of the bracket portion 42. Therefore, it is easy to operate the respective switches 44a to 44e with the index finger or the middle finger of the hand holding the handle member 31. Since the movement of the handle member 31 from the initial position can be detected by the movement position detecting unit 53, the brake control can be carefully performed when the braking mode is regenerated, and the sudden change of the braking force can be prevented. <Characteristics> (A) The left brake handle 16r (or the right brake handle 16) is a brake handle for a power-assisted bicycle that is driven by the motor 10 to assist the manpower.

Here, the first mode switch 44c, the second mode switch 44d, and the power switch 44e (or the light switch 44a and the screen change switch 44b) The arrangement of the bracket portion 42 instead of the φ is disposed in the mounting portion 41, whereby the first mode changeover switch 44c, the second mode changeover switch 44d, and the power switch 44e (or the light switch 44a and the screen changeover switch 44b) can be increased. Therefore, it is easy to operate: the first mode switch 44c, the second mode switch 44d, and the power switch 44e (or the light switch 44a and the screen switch) disposed on the left brake handle 16r (or the right brake handle 16f) (b) In the left brake handle 16r (or the right brake handle 10f), the bracket portion 42 has a mounting plane 42a that intersects the swing shaft 40 of the handle member 31, the first mode changeover switch 44c, the second The mode change switch 4 and the power-on-13-M419723 switch 44e (or the light switch 44a and the screen change switch 44b) are disposed on the mounting plane 42a. In this case, since the mounting plane 42a is disposed to intersect the swing axis 4〇, Therefore, it is easy to operate the first mode changeover switch 44c, the second mode changeover switch 44d, and the power switch 44e (or the light switch 44a and the screen changeover switch 44b) with the index finger or the middle finger of the hand holding the handle member 31. (C) The mode switching switch 44c and the second mode switching switch 44d are switches for electrically assisting mode switching of the electric assist bicycle. In this case, the first mode switching switch 44c and the second mode switching switch 44d can be used to perform the electric assist mode. Since the switching is performed, the electric assist mode can be easily switched. <Other Embodiments> The above description is directed to an embodiment of the present invention, and the present invention is not limited to the above-described implementation.
