Description

Frame element for a two-wheeled vehicle to accommodate an energy storage device

The present invention relates to a bicycle frame component for accommodating an energy storage unit, a corresponding bicycle frame, an energy storage unit mountable in the frame component, and an application of the frame The bicycle of the component.

When an electric bicycle is used, it is necessary to mount an associated energy storage device, such as a battery, on the bicycle 100 in a manner that does not affect the mobility of the driver as much as possible (see Fig. 1). The energy storage device is typically secured to a bicycle frame formed by the lower tube 110 and the saddle tube 120 and, as the case may be, the tube 130. It is in the case where the saddle tube 120 is provided that the energy storage can be mounted in the tripods 110, 120 and 130 or between the saddle tube 120 and the rear wheel, for example in a rear tripod or in Behind the saddle tube. In the last case, the distance between the pedal crank and the rear axle is increased to provide sufficient space for a generally large volume of energy storage. Another solution for installing the energy storage device is to secure it to the rear frame 140.

The publication EP 2 134 592 B1 discloses fixing the battery to the lower tube. For stability reasons, the lower tube is implemented as a multi-chambered tubular member carrying a load, and is provided with a battery for accommodating the battery. Intercepting department. According to this aspect, at least one chamber of the laterally exposed intercept portion extends in the multi-chambered tubular member and at least one other chamber is substantially intact.

EP 1 982 909 B1 discloses a combination of a battery and a bicycle frame, here One of the tubular members of the bicycle frame is provided with an upper edge that deepens the side wall for forming a portion of the laterally exposed recess. This snap-fit frame completely enters the recess to completely enclose the battery that is later inserted.

The present invention describes a frame body for a bicycle frame suitable for accommodating an energy supply unit And its associated bicycle frame and available energy supply unit and a bicycle that combines the frame element of the present invention with the energy supply unit of the present invention. The frame element is optionally embodied as a saddle tube, a lower tube or an upper tube which is at least partially hollow. In addition, the frame element is provided with a flat surface into which the elongated slot is placed. The elongated slot is for receiving the energy supply unit, such as a battery or a battery. The core of the invention is that the elongated slot extends completely within the flat face above the frame element, wherein the slot is completely surrounded by the flat face.

The advantage of this arrangement is that the design is simple because only one undercut needs to be placed This flat surface requires no additional outer corners. In addition, the slot is placed in the same plane as the flat surface when the power supply unit is inserted, which helps to implement the seal because only two dimensions need to be considered. In this way, the electric energy storage device for the electric bicycle can be mounted on the bicycle in a manner that requires an additional accessory that hinders the driving. After the energy storage device is buried in the bicycle frame, it is almost impossible to see from the outside that an energy supply unit is mounted on the bicycle (such as an electric bicycle).

The simplicity of the groove for the energy supply unit or the flat surface of the frame element The inner notch can also be realized by: in order to realize the long strip extension of the notch, only Two parallel or substantially parallel slits are placed in the flat face of the frame element (such as the pipe). Alternatively, the elongated strip may also have a plurality of serrations or a zigzag or trapezoidal shape. Further, another simple slit is provided at one of the two ends of the notch. A special undercut can be provided on the opposite end of the slot for mounting the support of the energizing unit. It is also possible to provide a slit which is simple and optionally parallel to the other end or a partial narrowing with an extension which is subsequently tapered.

According to a particular embodiment, the frame element, which can be embodied, in whole or in part, as a tubular part, has a substantially U-shaped cross section in the lower region, in addition to the flat surface. According to this solution, the U-shaped cross section can be provided with a plurality of bends which are shaped like sharp edges or multiple sharp edges in the shipbuilding industry such that the lower region appears slightly angular. As an alternative, the frame element at least partially has a generally square or trapezoidal cross section. A bottom portion is provided that is generally parallel to the flat surface, the flat surface being coupled to two side walls (eg, parallel wall portions). For aesthetic and stability reasons, the corresponding connecting ribs can be rounded.

A retaining element for securing or contacting the energizing unit may be provided in the slot. The energizing unit can be placed at one end of the slot and fixedly coupled to the frame member. In order to prevent undesired movement of the energy supply inside the frame element, the holding element may have a recess into which the extension of the handle of the energy supply unit is snapped. In particular, the extensions are mounted on opposite sides of the handle from a (rotating) support and are detachable from the recesses during a removal by a rotational movement. In particular, the hooks that can be caught in the recess are suitable for this.

According to one embodiment, the extensions or hooks can protrude from the end of the energy supply unit and snap into the holding element. The extensions or hooks may also not protrude beyond the end of the energizing unit, thereby mitigating the risk of breakage when dropped. However, as a necessary solution, the retaining element has corresponding sockets for the extensions or hooks which protrude from the end of the energizing unit end.

In addition to the contact element for contacting the energizing unit In addition, the retaining element can also have a lock for carrying out the stop. Alternatively, the lock function can also be electronically released or include an RFID (automatic) inquiry. Alternatively, a charging interface can also be incorporated into the holding element. In this way it is possible to charge the energy supply unit in addition to the contact, without having to remove the energy supply unit from the frame element.

According to a special modification of the present invention, one can be used to accommodate the power supply list. The trough of the element is placed in the slot. The groove body can be designed in one piece with the holding element or can be divided into two parts in order to independently manufacture the holding element having a corresponding function (fixing/contacting), but the holding element is stably connected to its function by a corresponding mechanical connection. The advantage of using such a tank is that it simply separates the socket of the energy supply unit from the interior of the frame element to prevent ingress of dirt or moisture into the energy storage. It also helps to keep the area where the energy supply unit is clean. Finally, in the case of such a trough, it is also advantageous to secure the energy storage in the slot without undesired movement.

Applying the frame component of the present invention to store an energy storage device for an electric bicycle, The point can be achieved by terminating the energy storage in a manner flush with the top surface of the flat surface. The frame element and the gap of the energizing unit can be sealed and insulated from dirt and moisture by a suitable seal around the slot or in the area above the energizing unit. The energizing means may also be secured to prevent vibration by utilizing the seal located in the area above the energizer or a corresponding flexible rim in the lower region. Thereby extending the service life of the energy supply device.

Figure 1 is a bicycle and its possible position for fixing the energy storage; Figure 2 is an energy storage device of the present invention and a mounting scheme in a pipe fitting of the bicycle frame; Figures 3a to d are for mounting the energy storage device In the frame tube; Figures 4a to c are for taking out the energy storage device from the frame tube; Figure 5 is a plan view of the energy storage device inserted into the frame tube; Figures 6a to c are the support members of the energy storage device during installation Different aspects and different aspects of the energy storage; Figures 7a and 7b take the energy storage device from the frame tube when using the diamond frame and the female vehicle; and Figures 8a and 8b are different designs of the energy storage device. .

As described in the opening paragraph of this document, the currently used energy storage device for electric bicycles is usually provided as an additional component on the prefabricated bicycle frame. When such accessories are provided, the installation space for the pump body or the beverage bottle is more limited, and thus such accessories may partially affect the driving comfort. To prevent this, the present invention uses the energy storage device as a removable device. The components are integrated into the bicycle frame.

By way of example, Figure 2 shows a frame member 210 of the present invention as a saddle tube that can be embedded in the frame member in a substantially flush manner. The frame member 210 can also be implemented as a lower tube or an upper tube, depending on the design of the bicycle frame. The frame member consists of a flat surface 260 and a remaining tubular member 270 located below it In the present embodiment, it is implemented as a U-shaped remaining tube member 280. Of course, the remaining tubular member 270 can also have other shapes, such as a single or multiple bent bottom, such as a trapezoidal or cubic shape. The frame member 210 can be in different mounting orientations for loading or unloading the energy supply unit 200 upwards, laterally or downwardly.

In order to accommodate the energy storage device 200 in the frame member 210, a long slot can be The port 220 is provided with a retaining member 240 at one end or a substantially complete tank 250. Wherein, the tank body can be integrated (ie, including a holding option and/or contact option) or a two-part. With a two-part solution, the retaining elements can be separated from the rest of the trough structure, but can be joined to each other.

The energy storage 200 is embedded in the slot 220 of the flat surface 260 of the frame member 210. To this end, a handle 230 is provided which is rotatably supported so that when the energy storage device 200 is inserted into the frame member 210, the handle is located in a recess in the region above the energy storage device 200. Thereby, the handle 230 can be smoothly projected on the flat surface 260 of the frame member 210.

Figures 3a to d show a cross section of the frame member 210 of the present invention and the insertion of the energy storage device 200. In the present embodiment, the frame member 210 is shown as an upper tube 130 in which the energy storage device 200 is inserted and removed in an upwardly facing manner. Of course, the frame member and its slot 220 can also be oriented to insert and/or remove the energy storage device 200 from the lateral or bottom-up. The retaining element 300 or 240 is placed on one end of the slot 220. As shown in Figure 3b, the retaining element is intimately coupled to the hollow profile of the remaining frame members 210 or 130. In this embodiment, the holding component 300 further has a locking member 310 and a charging interface 320, wherein the two functional components may also be arranged in another order or arranged side by side. A pin 330 serving as a fixing or stopping member is exemplarily provided on the holding member 300 for the energy storage device 200 to be engaged. The fixing or stopping element can also be arranged laterally, for example in the form of a flexible protruding bracket, ie in the side wall or in the groove On the other end of the body. The pin 330 can also assume a contact function.

Figure 3c shows the energy storage device 200 being embedded in the slot 220 or the slot 250. The energy storage device 200 is inserted in a rotational motion. Different rotational movements may be employed, depending on the manner in which the frame member 210 is mounted, see Figures 7a and 7b. For example, when using the typical diamond frame 700 shown in FIG. 7a, it is preferable to rotate the upper end (ie, from top to bottom) by the upper tube 130 and using the frame member 210 as the lower tube 110. When the female vehicle (Tiefeinsteiger) 710 shown in Fig. 7b is used, since the upper tube is not provided, it is more advantageous to perform the rotational movement around the lower end (i.e., from top to bottom). In principle, the energy storage can also be inserted in a vertical movement, see Fig. 3d.

4a to 4c are perspective views of the energy storage device 200 as it is removed from the frame member 210. view. As shown in Figure 4a, the surface of the energy storage 200 is substantially flush with the flat surface 260. Relative to the retaining element 300, the handle 230 of the energy storage device 200 is located in a recess on the surface of the energy storage device 200. The energy storage 200 can be easily removed by rotating the handle 230 about the rotary support. The handle 230 is also used as a grip for carrying an energy storage device. In a particular embodiment, the handle 230 can be automatically reset to its initial position, for example by a spring or magnet.

Figure 5 is an energy storage device mounted in the frame member 210 or its flat surface 260 Top view of 200. In this top view, the retaining element 300, which is inserted into one end of the slot 220, has a charging interface 520 in addition to the locking member 510. The lock is used to prevent the energy storage 200 from being removed, and the charging interface 520 is used to charge the energy storage 200. A charge status indicator 500 and an on/off button 530 are also provided on the energy storage device 200. This button 530 is used to additionally turn the power supply of the electric bicycle on or off.

Figures 6a through 6c show more aspects of the support of the energy storage device 200. Figure 6a A separate trough 250 is shown that is placed into the slot 220 of the frame member 210. In the figure, the retaining member including the lock member 510 and the charging interface 520 (which is closed by a closure member in the figure to prevent intrusion of dirt particles) is integrally connected to the tank body 250. In FIG. 6 b , two extensions 600 or hooks are provided, which protrude from the handle 230 beyond the rotational support of the handle and can snap into the corresponding recess 610 of the holding element. As an alternative to the view of FIG. 5, in the present embodiment, the state of charge indicator 500 is disposed in an arcuate section of the surround on/off button 530. In addition, the energy storage device 200 may also have a charging port 540 disposed sideways. Figure 6c shows the unit consisting of the energy store 200 and the two-part tank 250 and the retaining element 300. As shown, the extension 600 of the handle 230 protrudes in one manner from one end of the energy reservoir such that it can snap into the corresponding recess 610 of the retaining member 300. The engaged state is released by the rotation of the handle 230 to take the energy storage device 200 out of the trough 250 or from the slot 220. Furthermore, it can be seen that the one end of the trough body has a plurality of inverting elements 620 above the extension 600 for pressing the extensions 600 into the recesses 610. In this embodiment, the retaining element 300 can also have a charging interface, although not shown in Figure 6c.

The extension or hook 600 described above is designed to protrude from the end of the energy storage device 200 The ends are such as to snap into the corresponding sockets of the retaining element to effect a stop. As an alternative to the extensions or hooks, the extensions or hooks 600 can also be of a shorter or recessed design. In this case, the extensions or hooks terminate from the rotation support before the end of the energy storage device 200, so that the extensions or hooks do not protrude beyond the ends. The holding element is designed to extend at least partially in the upper region to the energy store in the inserted state of the energy store 200 . This is necessary because in this case, the sockets for the extension or the hook 600 are necessarily arranged above the energy storage device 200.

Figure 8a (energy storage is placed in the frame element) and Figure 8b (energy storage) A top view of a different design of the energy storage device 200. As shown, the charge indicator can be arranged linearly above or below the on/off button 530 or in a semi-circular shape. Further, the on/off button 530 may be disposed either inside the handle 230 on the surface of the energy storage device 200 or on the outside thereof.

Figure 9 illustrates yet another embodiment of the energizing unit of the present invention. In this embodiment, the extension of the handle has an S-shaped hook for snapping into the corresponding socket. With this special shape of the hook, the purpose of the stop can be achieved while the socket is inserted.
