The present disclosure relates to a remote control unit and to an electric bicycle according to the disclosure herein.
Electric bicycles, such as pedelecs or e-bikes, enjoy great popularity as an easy-to-use, emission-free means of transportation. Particularly suitable types of bicycles are available for different fields of application. These include, inter alia, bicycles optimized for leisure time use or for the way to work, on the road or in light terrain (for example, city bikes or touring bikes,) and e-mountain bikes (E-MTB), which have been developed in various designs for off-road use and especially for mountainous terrain. Electric bicycles offer the possibility to increase the operating radius without overstraining the rider and to increase the average driving speed.
Electric bicycles are known from the prior art, which in addition to a drive unit and a battery unit also have a display unit and a remote control unit for the display unit. The remote control unit is situated in the region of a handlebar grip remote from the display unit and is provided with assistance selection keys for the choice of the support level of the electric drive. Furthermore, the remote control unit has an input device for menu navigation and selection of menu items shown on the display unit. A disadvantage of such remote control units is that the frequently used assistance selection keys and the input device are situated next to one another and, for this reason, are not ergonomically operatable by the thumb of the rider. Often, a safety-critical repositioning of the hands of the rider to operate the input device is necessary.
For this reason, an object of the present disclosure is to provide a novel remote control unit, which aligns electrically assisted mobility with the demands of athletic and lifestyle-oriented cyclists.
This object is achieved by a remote control unit and by an electric bicycle having features disclosed herein.
A remote control unit for the display unit of a bicycle according to the present disclosure is situated in the region of a handlebar grip remote from the display unit and has assistance selection keys for the selection of the assistance level and has at least one input device for the menu navigation and selection of menu items shown on the display unit. According to the present disclosure, an input unit and an assistance selection key are situated along a common line. The common line can be multi-dimensionally curved in an ergonomically arcuate manner. The input device and the keys are preferably situated one below the other in such a manner that they are ergonomically operable by the thumb of the rider. A safety-critical repositioning of the hands of the rider is not required for operating the assistance selection keys and the input device.
In a particularly preferred embodiment of the present disclosure, the input device is configured as a joystick. As a result, the menu navigation and selection of menu items shown on the display unit can be carried out intuitively and ergonomically, preferably by the thumb of the rider.
The joystick is preferably movable in all four directions (upward and downward, left and right), the selection/selection of menu items being carried out with the aid of pressure onto the joystick (pressure function). The menu navigation and selection of the menu items is carried out with the multi-functional joystick, so that no further operating elements are required. For this reason, the remote control unit is configured in an extremely compact and aesthetically pleasing manner. The joystick may have a backlit symbol, in particular a rectangle having rounded corners.
It has proven to be particularly advantageous if the assistance selection keys are situated in an inclined manner to one another. In this instance, the selection of the assistance level may be carried out by the thumb of the rider. The assistance selection keys preferably form a concave section. The thumb can rest between the keys situated one above the other so that the operation is carried out intuitively, the assistance selection key for increasing the assistance level preferably being situated in the front in the direction of travel and the assistance selection key for reducing the assistance level in the rear in the direction of travel.
Furthermore, it is preferable that the assistance selection keys are inclined toward the hand of the rider. The operation can be carried out ergonomically preferably by the thumb of the rider.
The assistance selection key for increasing the assistance level is preferably marked with a plus symbol and the assistance selection key for reducing the assistance level is preferably marked with a minus symbol. The symbols are preferably backlit and, for this reason, recognizable even in conditions of poor visibility.
Regarding manufacturing technology and operation, it has proven advantageous if the assistance selection keys have a free actuation section facing the hand of the rider and an elastically mounted end section.
According to a preferred embodiment of the present disclosure, a light switch is offset to the side in the area between the assistance selection keys. Preferably, the light switch is situated in the direction remote from the hand of the rider next to the assistance selection keys. It has proven to be particularly ergonomic if the light switch is situated laterally offset in the middle between the assistance selection keys.
Preferably, the light switch has three functions, each of which are activated sequentially by pressing a key: keep key pressed (>2s), light on/off; push key, dipped beam, push key for the second time, light lights up. As a result, advantageously there is one button for light on/low/high/off. The light switch may have a backlit light symbol.
In electric bicycles having an electronic gearshift of the geared motor, the remote control unit preferably has a centrally mounted rocker switch for gear selection along a pivot axis. According to the present disclosure, it is advantageous if the rocker switch has two actuation surfaces, a first actuation surface being situated on a side facing the hand of the rider and a second actuation surface being situated on a side facing away from the hand of the rider. Preferably, input device, assistance selection keys and rocker switch are situated along a common line. The keys are preferably situated one below the other in such a manner that they are ergonomically operable by the thumb of the rider. A safety-critical repositioning of the hands of the rider is not required for operating the assistance selection keys and the rocker switch.
In a preferred embodiment of the remote control unit, the remote control unit has an upper part and a modularly exchangeable lower part, the rocker switch being assigned to the lower part. For this reason, the remote control unit is modularly adaptable to bicycles with and without an electric geared motor. For this purpose, a lower part designed as a clamp half is mounted with or without a rocker switch. A fastening portion of the upper part and of the lower part each preferably engages around one half of the handlebar. The upper part and lower part are preferably electrically connected with the aid of a flexible band.
The rocker switch preferably has an approximately centrally situated automatic key. The automatic key preferably does not rock and activates the automatic gear selection. For example, it activates the first or second gear of the geared motor.
When viewed in the direction of the handlebar grip axis, the input device, assistance selection keys and rocker switch preferably extend along a convexly arcuate common line, the curvature curve of which is ergonomically adapted to the movement range of the thumb of the rider.
Preferably, the remote control unit has a vibration motor. For example, having reached the highest assistance level can be signaled with the aid of a short vibration. Furthermore, a switching operation can be proposed with the aid of a short vibration. Preferably, a gear proposal is made on the display unit, for example, an upward arrow on the display suggesting to shift up, the vibration alerting the rider that the display unit is displaying new information.
A bicycle according to the present disclosure has a remote control unit for the display unit of the electric bicycle, the remote control unit being situatable in the region of a handlebar grip remote from the display unit and having assistance selection keys for the selection of the assistance level and having at least one input device for the menu navigation and selection of menu items shown on the display unit. According to the present disclosure, input unit and assistance selection keys are situated along a common line. As a result, a particularly ergonomic and safe operation by the rider is enabled.
In a particularly preferable exemplary embodiment of the present disclosure, an electronic control unit, a drive unit and a battery unit are furthermore provided. It has been proven to be particularly advantageous if the electronic control unit is situated in the seat tube of the bicycle frame. As a result, a highly integrated interaction between the frame and the assembly elements is achieved. The design of the battery unit in particular situated in the down tube of the bicycle frame is not limited and more space for the battery cells and thus a high operating distance is available. Because of the thermal decoupling of battery unit and electronic control unit, a high efficiency is achieved. Special battery housings having fastening options for the control unit are not required. Overall, a compact, homogeneous frame shape of highest strength is achieved in this variant. The concept according to the present disclosure therefore also meets the demands of a lifestyle-conscious, ambitiously sportive rider.
It has been proven to be particularly advantageous if the electronic control unit is situated in the lower region of the seat tube adjacent to the drive unit. As a result, the electrical line length is reduced to a minimum. As a result, the electric bicycle has an optimized frame cross-section having constructively and aesthetically best features for optimized space requirements.
In a preferred exemplary embodiment, the electronic control unit is attached to the frame-side drive carrier (motor bracket) of the drive unit. As a result, no further fastening elements are needed. A weight reduction can be achieved.
The electronic control unit is preferably provided with line connections only at an end section facing the drive unit, so that the construction is simplified and the line lengths are minimal. All lines are preferably guided out at the bottom of the frame.
According to a particularly preferred embodiment of the present disclosure, at least one stop, in particular a fastening element of the bottle holder, for example a bottle holder bush, for the seat post is situated above the electronic control unit. As a result, damage to the electronic control unit by a long seat post is prevented.
Preferably, at least one signal line of the remote control unit is connected to the display unit and at least one electrical line of the display unit is connected to the electronic control unit. It has proven to be particularly advantageous if only one bus line is provided between the remote control unit and the display unit. Furthermore, it is particularly advantageous if only one bus line is provided between the display unit and the electronic control unit. The number of cables to be laid, and thus weight and assembly costs, are therefore minimized.
It is particularly advantageous if the brake signal lines are connected directly to the display unit. As a result, only one electrical line between the electronic control unit and the display unit is required. The number of lines is reduced. When the brake is applied, the brake light is activated.
Accordingly, it is preferable if the remote control unit is connected to the display unit by a single bus cable including a plurality of signal lines.
According to a particularly preferred embodiment of the present disclosure, sensor lines are each connected directly to the electronic control unit. In this instance, the number of lines is also reduced. In particular, the following may be provided: a sensor of the kickstand (safety deactivation when the stand is folded down), a sensor of the gearing, acceleration sensors (3D gyro and accelerometer), a sensor for detecting a bicycle folding in folding bikes, pressure sensors and temperature sensors.
The communication is preferably carried out with the aid of CAN bus methods, particularly preferably by CAN open methods. A CAN translator is provided for adaptation requirements.
The present disclosure can be used universally in all types of bicycles, especially in mountain bikes (both in hardtail or full-suspension design), but also can be implemented in other bicycles, for example, road bike frames and, thus, ultimately resulting in a touring, city or cross-bike or other modern types of bicycles. Because of its compact, attractive design, it enables the construction of bikes which largely combine the advantages of a classic bicycle and an electric bicycle.
A preferred embodiment of the present disclosure is subsequently explained in greater detail in reference to the appended drawings. For this purpose, in detail:
