Technical Field

The invention relates to a holding system for an energy store and to a two-wheeled vehicle having a frame with such a holding system.

Background

In order to receive the battery and the accumulator on the frame of a two-wheeled vehicle, in particular an electric bicycle, retaining systems are known which enable both mechanical fixing and electrical contacting. In general, the two functions (locking and contacting) are performed at different points of the holding system in order to avoid sensitive contact damage.

From DE 102016213903 Al, for example, a two-part retaining system is known in which a movable locking tongue is provided on the catch side of the retaining system, which locking tongue engages in a corresponding recess of the energy store or in a corresponding recess of a retaining device arranged on the energy store.

DE 69734265T 2 discloses a housing which is attached to the frame of a bicycle in order to receive a battery container. For locking, a latching hook with a spring is described here, which is first pressed back by inserting the battery container into the housing and then engages into an engagement groove of the battery container.

Another way of locking the battery in the housing to the bicycle frame is known from document WO 2017/009637 Al. In this case, the rotary element connected to the catch can block the lever element located in the holder in order to prevent the movement of the locking tongue.

From document EP 2280436 a2, a battery pack locking device is known, in which a closure plate, which is fastened rotatably on a spring, engages in a closure pin.

Disclosure of Invention

The following tasks are to be achieved by the invention: a retaining system is described which can be used to lock an energy store, in particular of an electrically operated two-wheeled vehicle. The holding system is designed according to the independent claims such that it does not transmit forces from the energy store to the holding system in the locked or latched position.

The holding system comprises a catch with a movable locking pin. The locking pin engages in an opening of a closure bolt (Schlie β riegel), which is also movable, in such a way that the closure bolt can be moved from the closed position into the open position or vice versa by actuating the catch and thus the locking pin. For this purpose, the locking pin is moved mechanically along the inside of the opening, for example in such a way that the locking pin is rotated by the catch. The invention is based on the idea of configuring the closing bolt in the opening in such a way that an inwardly directed first profile is provided, which, in conjunction with the locking pin, limits the mobility of the closing bolt at least in the closed position.

With this configuration, the closure bolt cannot be brought into the unlocking position or into a position in which the energy store can be removed, in particular without actuating the locking catch.

For example, the profile may be configured in the form of a support. The locking pin can be provided here as a stop for the first profile in the locked position. For this purpose, it can be provided that the mechanical contact between the stop, i.e. the profile or the support, and the locking pin is only achieved after a (small) distance has been overcome. It is hereby achieved that a small clearance is provided so that vibrations are not directly transmitted from the first profiled section to the pin. Furthermore, the distance which has to be overcome by the physical spacing between the first profile/support and the locking bolt is such that no force can be exerted on the locking bolt or on a catch connected thereto during use of the introduced energy store. Damage to the latch due to vibrations can be avoided by this force decoupling.

The catch is arranged such that it moves the locking pin in the opening of the closure latch. The movement may be, for example, a rotational movement which rotates the locking pin from the region into a further portion of the opening, in which the locking pin can act as a stop for the first profile.

Furthermore, it can be provided that the closure bolt is rotatably supported. For this purpose, a foot point or a pivot point can be provided, at which the closure latch is rotatably mounted. On the other hand, the closure bolt can be formed with an opening in the upper part and a nose which can be screwed rotatably into a corresponding receptacle of the energy store or into a receptacle of a retaining plate on the energy store. In this case, the closing bolt can be rotated about a rotation point in the lower region by actuating the catch or the locking pin.

In a further development of the invention, a second profile can be provided in the outer region of the closure bolt facing the energy store. The second profile can form a nose which locks the energy store in the locked position. Furthermore, the second profile can be configured in such a way that, when the energy store is inserted, the second profile moves the closure latch to the side, for example in a rotational movement, in order to thus release the path of the energy store into the retaining system.

Further advantages result from the following description of embodiments or from the dependent claims.

Detailed Description

The closing mechanism of the retention system according to the invention is illustrated in fig. 1. Here, a closure latch 100 is provided, which has an opening 185. In this opening 185, a first shaped portion 180 in the form of a support element is formed, which is arranged opposite the locking pin 140 in the locked position. In addition, a second molding 190 is provided that points outwardly from the closure latch 100, away from the opening 185. The second profile 190, for example a nose, can engage in a corresponding holder 130 of the energy store 110 and mechanically lock the energy store accordingly. In this case, it can be provided that the holder 130 is part of the energy store 110 or of a holding device or holding plate 120 applied to the energy store 110. As can be seen from fig. 1, the closure bolt 100 is mounted on a foot point 160 so as to be rotatable in a direction of rotation 150. By means of this rotatable bearing, the closure bolt 100 can be brought from the closed position into the open position 105 (indicated by dashed lines in fig. 1 and shown again in fig. 5) and vice versa. In this case, during latching or locking, the second profile 190 presses against the holder 130, so that a mechanical fastening is achieved.

The movement of the closure latch 100 is produced by a catch 148, by means of which the locking pin 140 can be changed in its position (for illustration, see also fig. 5, which shows the locking pin 145 in the unlocked position 105). By actuating the catch 148, the locking pin 140 can be moved in the opening 185 and thus the closure bolt 100 can be rotated from one position into the other.

The first profile 180 and the locking pin 140 are arranged spaced apart from one another in the locked position, so that no direct mechanical contact exists between these two elements. This spaced-apart arrangement makes it possible to: vibrations of the energy store 110 during use, for example in the case of being held on or in a bicycle frame during driving, are not transmitted to the locking pin 140 and therefore to the catch 148 and therefore do not put the locking pin 140 and the catch 148 under load. Thus, a coupling of forces to the catch 148 in the longitudinal direction 170 can be avoided by this configuration according to the invention.

In fig. 2a to c, the locking pin 140 is shown in different positions in the opening 185 of the closure bolt 100. Fig. 3a to f show exemplary different configurations of the locking pins 141 to 146. The different (rotational) movements of the locking pin 140 within the opening 185 are additionally shown in fig. 3d to f and fig. 4a and b. Here, the locking pin 140 can be rotated or moved upward (in direction 152) or downward (in direction 154) out of the region of a portion of the opening 185, in which region it can be used as a stop for the first profile 180.

Fig. 6 shows a further advantageous configuration of the closure bolt 100 or of a second profile 190 formed thereon. When the energy store 110 is inserted into the frame 200 of a two-wheeled vehicle, for example, the bolt 100 may be closed in the way. By means of the special configuration of the second profile 190, it is possible to transmit and convert the force 210 exerted when placing on the second profile 190 into a rotation about the foot point 160 when inserting the energy store 110 or when using the holding plate 120 placed on the energy store 100. Here, the force 210 is transmitted within the closure latch 100 first along the second profile 190 and then along the force lines 220, 230, and 240. Since in this case the detent 140 is located outside the region of the opening 185, in which it can be used as a stop for the first profile 180 in the interior of the opening 185, the closure bolt 100 can be rotated accordingly in the direction of rotation 150.
