Disclosure of Invention

The present invention shows a fixing device according to the features of claim 1 and a system of a fixing device according to the invention and a light motor vehicle or a battery charging device according to the features of claim 11.

Further features and details of the invention result from the dependent claims, the description and the drawings. Features and details that are described in connection with the fixation device according to the invention naturally also apply in connection with the system according to the invention and vice versa, so that the disclosure of the individual aspects of the invention is or can always be referred to reciprocally.

According to a first aspect, the present invention provides a fixing device for fixing a vehicle battery for driving a light vehicle. The fixing device according to the invention comprises a housing body with a receiving space for receiving the at least one vehicle battery and with an opening area for moving the at least one vehicle battery along a vertical axis of the housing body into or out of the receiving space. Furthermore, the fixing device comprises a clamping device, wherein the clamping device comprises at least one clamping unit with at least one clamping element arranged in the opening area of the housing body on a housing body part of the housing body, wherein the at least one clamping element for transferring the at least one clamping element between an open state and a closed state is movable on the Housing body part is stored. In the open state of the at least one clamping element, the at least one clamping element releases the opening area of the housing body for moving the at least one vehicle battery into or out of the accommodation space. In the closed state of the at least one clamping element, the at least one clamping element at least partially covers the opening area of the housing body for holding the at least one vehicle battery in the accommodation space.

The vehicle battery for driving a light vehicle is particularly for moving the vehicle. In other words, in particular the energy stored in the vehicle battery is supplied to an electric motor of the light motor vehicle for driving the light motor vehicle.

In particular, the vehicle battery is to be understood as a battery module with a plurality, preferably a large number, of battery cells. The vehicle battery may include a battery case. Furthermore, the vehicle battery can include a battery module monitoring unit for monitoring the function of the vehicle battery. In particular, the vehicle battery itself has no internal damping elements for mechanically damping mechanical loads such as vibrations and shocks, which can occur when the light motor vehicle is moving. Internal damping elements are, in particular, to be understood as meaning damping elements which are arranged in an interior space of a battery housing of the vehicle battery. In particular, at least one battery cell is accommodated in the interior of the battery housing.

In particular, two-wheelers and/or three-wheeled vehicles and/or light four-wheeled vehicles are to be understood as light motor vehicles. In particular, light motor vehicles are not to be understood as meaning heavy four-wheeled vehicles, for example heavy passenger cars. In particular, the vehicle battery for driving the light motor vehicle has a battery capacity of up to a maximum of 35 kWh, preferably up to a maximum of 20 kWh, very preferably up to a maximum of 10 kWh.

In particular, when the at least one clamping element is in the closed state, the at least one clamping element at least partially covers the opening area of the housing body in such a way that a vehicle battery held in the receiving space is at least partially held in a form-fitting manner by the clamping element, in particular is at least partially held in a form-fitting manner by the clamping element along the vertical axis . The vehicle battery is preferably not held in a materially bonded manner in the accommodation space of the housing body of the fixing device. In other words, the vehicle battery is held in the housing body or the receiving space of the housing body, in particular in a detachable manner. The covering of the opening area of the housing body by the at least one clamping element when the clamping element is in the closed state is to be understood in particular in such a way that when the clamping element is in the closed state, the clamping element protrudes at least partially into the opening area of the housing body in order to hold or . to fix. In particular, in the closed state of the clamping element, the clamping element protrudes less than 3 cm, preferably less than 1 cm, very preferably less than 0.5 cm into the opening area of the housing body. The clamping element can thus be transferred between the open state and the closed state particularly quickly and easily, and a vehicle battery can be replaced particularly quickly. However, it is also conceivable that when the at least one clamping element is in the closed state, the at least one clamping element or a plurality of clamping elements completely or essentially completely covers the opening area of the housing body. Thus, the vehicle battery can be held particularly securely in the accommodating space of the housing body.

Furthermore, the housing body can be made from a plastic and/or from a metal, with the housing body in particular being made from sheet metal.

The opening area of the housing body is to be understood in particular as an opening in the housing body, via which the vehicle battery can be moved into or out of the receiving space along the vertical axis of the housing body when the at least one clamping element is in the open state. The height axis of the housing body is in particular perpendicular or essentially perpendicular to the opening area of the housing body.

Furthermore, the housing body of the fixing device can have at least one arrangement interface, in particular on at least one outside of the housing body, for arrangement on a counter-arrangement interface of the light motor vehicle, in particular a body of the light motor vehicle, or on a counter-arrangement interface of the battery charging device. It is also conceivable that the housing body of the fixing device has several arrangement interfaces, in particular on at least one outside of the housing body, for arranging the housing body on a counter-arrangement interface of the light motor vehicle or the battery charging device.

In particular, the at least one clamping element can be transferred from the closed state to the open state manually, e.g. by means of manual force, and/or by means of an actuator element, in particular by means of an actuator element that can be controlled by a control device, of the fixing device.

The at least one clamping unit of the clamping device of the fixing device can also have a number of clamping elements, with the number of clamping elements preferably being of the same or similar design. The multiple clamping elements of the at least one clamping unit can each be transferred between the open state and the closed state independently of one another. It is also conceivable that several clamping elements of a clamping unit or several clamping units are operatively connected to one another, so that the several clamping elements are transferred between the open state and the closed state depending on one another or together. The at least one clamping element is in particular essentially plate-shaped, preferably plate-shaped, or essentially rod-shaped, preferably rod-shaped. Furthermore, in particular the at least one clamping element can extend over the entire length or essentially over the entire length of the at least one vehicle battery. The at least one vehicle battery can thus be held in the accommodation space in a particularly advantageous manner. Furthermore, the clamping device of the fixing device can also comprise a plurality of clamping units, each with one clamping element or with a plurality of clamping elements each, the plurality of clamping units or the plurality of clamping elements preferably being of the same or similar design. In particular, explanations and/or features and/or details that are mentioned for a clamping unit and/or a clamping element can also be transferred to other clamping units or other clamping elements and vice versa.

Advantageously, with the fixing device according to the invention, a vehicle battery can be attached to a vehicle battery particularly easily and/or securely Light motor vehicle, eg. An electric scooter, be fixed. Furthermore, the vehicle battery can be exchanged, ie installed and/or removed, particularly quickly and easily.

It can be advantageous if, in a fixing device according to the invention, the at least one movable clamping element is mounted so that it can rotate about a clamping element axis, with the clamping element axis in particular being perpendicular or essentially perpendicular to the vertical axis of the housing body, and/or that the at least one movable clamping element is mounted in a Guide of the housing body is slidably mounted to convert the at least one clamping element between the closed state and the open state. The transfer of the at least one clamping element between the closed state and the open state can thus take place particularly easily and quickly. For example, if the at least one movable clamping element is supported so that it can rotate about the clamping element axis, the at least one clamping element can be rotated from the closed state to the open state via an insertion force for inserting the vehicle battery into the receiving space of the housing body, in that the at least one clamping element is rotated out of the opening area . The clamping element can be rotated out of the opening area by inserting the vehicle battery, ie by the vehicle battery itself. In particular, the vehicle battery is inserted far enough into the receiving space until the at least one rotatably mounted clamping element rotates from the open state back to the closed state, e.g. by means of a return element of a return device of the fixing device. By rotating the clamping element back from the open state to the closed state, the vehicle battery is thus held in the receiving space. With the sliding mounting of the at least one movable clamping element, the at least one clamping element can be pushed from the closed state into the open state via an insertion force for inserting the vehicle battery into the receiving space of the housing body, in that the at least one clamping element is removed from the opening area, in particular by the vehicle battery itself. is pushed. In particular, the vehicle battery is inserted far enough into the receiving space until the at least one slidably mounted clamping element slides back from the open state to the closed state, e.g. by means of a return element of a return device of the fixing device. By pushing back the at least one clamping element from the open state to the closed state, the vehicle battery is thus held in the receiving space. It is also conceivable that in particular the at least one movable clamping element is mounted such that it can rotate about a clamping element axis and is also mounted such that it can be slid on a guide of the housing body in such a way that the vehicle battery can be inserted into the receiving space by rotating the movable clamping element through the vehicle battery, it being possible in particular for the vehicle battery to be removed only via a pushing or pulling movement of the movable clamping element, for example manually and/or by means of an actuator element of the fixing device. The vehicle battery can thus be inserted into the accommodation space of the housing body in a particularly simple manner by means of the vehicle battery itself, with a manual manual sliding movement on the at least one clamping element being required, for example, to remove the vehicle battery from the accommodation space. In this way, an unintentional removal of the vehicle battery from the receiving space can be prevented in a particularly reliable manner.

Advantageously, in a fixing device according to the invention, the at least one movable clamping element can be embodied as dimensionally stable. In other words, the at least one movable clamping element is resistant to mechanical pressure and/or heat. It is thus possible to ensure that the at least one vehicle battery is held in the accommodation space of the housing body in a particularly secure manner. Dimensionally stable can in particular also be understood as dimensionally stable. The at least one dimensionally stable clamping element can have a metal and/or a plastic, for example. In particular, the at least one dimensionally stable clamping element can consist of a metal or a plastic.

With particular advantage, in a fixation device according to the invention, the at least one movable clamping element can be operatively connected to a restoring element of a restoring device of the fixation device, with the restoring device of the fixation device storing restoring energy with the at least one restoring element by transferring the movable clamping element from the closed state to the open state, in order to the stored restoring energy to convert the at least one movable clamping element from the open state back to the closed state. The at least one movable clamping element can thus be transferred from the open state to the closed state in a particularly simple manner. The at least one restoring element of the restoring device of the fixing device is a spring, for example. A spring as a restoring element can be stretched or compressed, for example, by transferring the at least one clamping element from the closed state to the open state, in order to provide restoring energy for the (return) transfer of the at least to store a movable clamping element from the open state to the closed state. A spring as a restoring element is advantageously particularly inexpensive.

According to a further preferred embodiment, a fixing device according to the invention can have a stop element for the at least one clamping element for holding the at least one vehicle battery in the receiving space in the opening area of the housing body. Thus, a vehicle battery held in the accommodating space of the housing body can be guided out along the height axis of the housing body by the clamping element together, i. H. in combination with the stop element can be prevented. In particular, the stop element blocks a movement of the at least one clamping element out of the opening area of the housing body, in particular out of the opening area of the housing body along the height axis of the housing body, and thus an unintentional removal of a vehicle battery held in the accommodation space of the housing body. The stop element for the at least one clamping element for holding the at least one vehicle battery in the receiving space can be formed, for example, by a (further) housing body part of the housing body. Furthermore, the at least one stop element can simultaneously form a guide for the at least one clamping element during the transfer of the at least one clamping element between the closed state and the open state.

It can be advantageous if, in a fixing device according to the invention, the fixing device has at least one elastically deformable damping element, in particular a spring and/or an elastically deformable damping layer, for mechanical damping of the at least one vehicle battery held in the receiving space of the housing body. In this way, mechanical loads, which can occur, for example, while the light motor vehicle is moving, can be particularly advantageously mechanically damped. Due to the at least one elastically deformable damping element, the number of internal damping elements arranged in a battery housing of the vehicle battery for mechanically damping mechanical loads such as vibrations and shocks can advantageously be reduced. A spring, in particular a tension spring, as an elastically deformable damping element can be particularly cost-effective. A damping layer, for example made of a polymer, in particular rubber, as an elastically deformable damping element can be arranged in a particularly simple manner, in particular can be injection-molded onto an inner side of the housing body in a particularly simple manner. The at least one elastically deformable damping element can be arranged in particular on an inside of the housing body.

In a fixing device according to the invention, the at least one elastically deformable damping element, in particular at least one spring and/or an elastically deformable damping layer, can advantageously be arranged in a bottom region of the receiving space. The bottom area of the receiving space or of the housing body is in particular opposite the opening area of the housing body. Mechanical loads in particular along the height axis of the housing body can be particularly advantageously damped by the damping element that is at least partially arranged in the base region, in particular by a spring, preferably by a tension spring. Furthermore, in the case of a spring, in particular a tension spring, with a sufficient stroke (as a damping element), large tolerances can be compensated both by the vehicle battery and by the receiving space of the housing body. Advantageously, a spring arranged in the bottom area of the receiving space, in particular a tensioning spring, can additionally have a rubber element in order to protect the spring, in particular a tensioning spring, against mechanical loads. In particular, in addition to the damping element arranged on the base area, a (further) elastically deformable damping element can be arranged at least partially on an inner side of the housing body. It is also conceivable that the fixing device has a plurality of elastically deformable damping elements arranged on the inside of the housing body in addition to the damping element arranged on the base area. In particular, it is conceivable here for elastically deformable damping elements to be arranged on a side wall or on a plurality of side walls of the inside of the housing body. Mechanical loads transverse or substantially transverse to the vertical axis of the housing body can be particularly advantageously damped by the damping elements arranged at least partially on the side wall or the plurality of side walls of the housing body.

In a fixing device according to the invention, the at least one movable clamping element can particularly advantageously have a protective section for protecting the movable clamping element against mechanical loads, in particular while the light motor vehicle is moving, at an end that contacts the at least one vehicle battery. Thus, on the one hand, holding the at least one vehicle battery in the receiving space particularly advantageously dampened, on the other hand damage to the clamping element can be prevented. The end of the at least one clamping element that contacts the at least one vehicle battery is in particular the part of the at least one clamping element that at least partially covers the opening area of the housing body when the at least one clamping element is in the closed state. The protective section on the end of the at least one clamping element that contacts the vehicle battery can have, in particular be, a polymer element, for example a rubber element. It can thus be particularly advantageous to protect the at least one clamping element from mechanical loads, in particular while the light motor vehicle is moving. It is also conceivable that the protective section has, in particular is, a pivot bearing on the end of the at least one clamping element that contacts the vehicle battery. In this way, wear and tear on the end of the at least one clamping element that contacts the at least one vehicle battery can be kept particularly low.

According to a further preferred embodiment, in a fixing device according to the invention, the at least one movable clamping element can be designed to be pointed or curved, in particular rounded, at an end that contacts the at least one vehicle battery. The at least one clamping element can thus be transferred between the closed state and the open state in a particularly simple and/or advantageous manner. In particular, the pointed end of the at least one clamping element is wedge-shaped. For example, if the at least one movable clamping element is slidably mounted in a guide of the housing body, the vehicle battery can be inserted into the vehicle compartment particularly easily because the end of the at least one clamping element is pointed or curved, in particular rounded, since it simplifies displacement of the clamping element can be done. Furthermore, when the at least one movable clamping element is mounted so that it can slide in the guide of the housing body, it is also particularly easy to remove the vehicle battery from the vehicle compartment due to the pointed or curved, in particular rounded, end of the at least one clamping element, since the clamping element can be displaced is simplified.

It can be advantageous if a fixing device according to the invention has at least one actuator element for transferring the at least one movable clamping element at least from the closed state to the open state, in particular for converting the at least one movable clamping element from the closed state to the open state for moving the at least one Has vehicle battery from the receiving space of the housing body. Thus, the at least one movable clamping element can be transferred from the closed state to the open state in a particularly simple manner. The actuator element is preferably, in particular only, for transferring the at least one movable clamping element from the closed state to the open state when the at least one vehicle battery is removed or removed from the accommodation space of the housing body. Thus, an unintentional removal of a vehicle battery held in the receiving space of the housing body along the height axis of the housing body can be prevented by the clamping element in a particularly advantageous manner. The actuator element can be an electromagnet, for example. Furthermore, the actuator element is in particular an actuator element that can be controlled by a control device, for example a control device. It is also conceivable that the actuator element is operatively connected to the at least one movable clamping element parallel to a restoring element of a restoring device, with the actuator element in particular working against the restoring element. For example, when the actuator element is in a de-energized state, for example when the actuator element is de-energized, the clamping element can be moved into the closed state or held in the closed state by the restoring element. The vehicle battery can thus be held particularly securely in the fixing device even when the actuator element is in a de-energized state.

According to a second aspect, the present invention shows a system consisting of a fixing device designed according to the invention and a light motor vehicle or a battery charging device for charging a vehicle battery for driving a light motor vehicle, the fixing device having at least one arrangement interface to a counter-arrangement interface of the light motor vehicle or arranged at a counter-array interface of the battery charger.

In particular, the light motor vehicle can have a body with the counter arrangement interface for arranging the arrangement interface of the fixing device. In particular, the housing body can be formed at least partially in one piece with the body of the light motor vehicle. Preferably, the housing body of the fixing device is a part of the body of the light vehicle.

Furthermore, in particular the (at least one) arrangement interface of the fixation device arranged on the housing body of the fixing device.

Furthermore, explanations and/or features and/or details that are mentioned for the light motor vehicle can also be transferred to a battery charging device for charging the vehicle battery and vice versa, insofar as they make (technical) sense.

The system according to the second aspect of the invention thus has the same advantages as have already been described for the fixation device according to the first aspect of the invention.

1 and 2 disclose a side view of an embodiment of a fixing device 100 according to the invention for fixing a vehicle battery 120 for driving a light motor vehicle 200. The fixing device 100 has a housing body 10 with a receiving space 13 for receiving the at least one vehicle battery 120 and with an opening area 16 for moving the at least one vehicle battery 120 along a height axis HA of the housing body 10 into or out of the accommodation space 13. Furthermore, the fixing device comprises a clamping device 30, wherein the clamping device 30 comprises a clamping unit 32a with a clamping element 33 arranged in the opening area 16 of the housing body 10 on a housing body part 11 of the housing body 10, in particular a dimensionally stable clamping element 33. The clamping element 33 of the clamping unit 32a is in particular a clamping lever. Furthermore, the clamping element 33 is movably mounted on the housing body part 11 for transferring the clamping element 33 between an open state OZ and a closed state SZ of the clamping element 33, wherein in the open state OZ of the clamping element 33 the clamping element 33 uses the opening region 16 of the housing body 10 to move the at least releases a vehicle battery 120 into or out of the accommodation space 13 (see 2 ).

The two clamping elements 33 can be rotated out of the opening area 16 by inserting the vehicle battery 120, ie by the vehicle battery 120 itself. In particular, the vehicle battery 120 is inserted far enough into the receiving space 13 until the two rotatably mounted clamping elements 33 rotate from the open state OZ back to the closed state SZ. For turning back, the two clamping elements 33 are additionally each operatively connected to a restoring element 51a or 51b of a restoring device 50 of the fixing device 100, whereby the transfer of the two clamping elements 33 from the closed state SZ to the open state OZ, the restoring device 50 or the two restoring elements 51a or 51b each store restoring energy in order, by means of the respective stored restoring energy, to move the respective clamping element 33 of the clamping unit 32a or the clamping unit 32b from the open state OZ back to to convert the closed state SZ. Furthermore, the additional, elastically deformable damping element 70 arranged in the floor area 17 is, in particular, a tension spring for the mechanical damping of the at least one vehicle battery 120 held in the receiving space 13 of the housing body 10 HA is kept free of play or substantially free of play. In order to hold the vehicle battery 120 in the receiving space 13 , the fixing device also has a stop element 60 for each of the two clamping elements 33 . It is thus possible to prevent vehicle battery 120 from moving out due to rotation of the two rotatably mounted clamping elements 33 . To move vehicle battery 120, for example, a (horizontal) pushing or pulling movement of the at least rotatably mounted clamping elements 33 may be necessary, for example manually and/or by means of an actuator element 80 (not shown) of fixing device 120, in order to to transfer both clamping elements from the closed state SZ to the open state OZ. For this purpose, the two rotatably mounted clamping elements 33 can in particular be mounted so as to be rotatable and sliding.

The fixing device 100 each has a housing body 10 with a receiving space 13 for receiving the at least one vehicle battery 120 and with an opening area 16 for moving the at least one vehicle battery 120 along a height axis HA of the housing body 10 into or out of the accommodation space 13.

In particular, the two clamping elements 33 each designed as clamping tongs form a (common) clamping tong. The two clamping elements 33 of the clamping units 32a and 32b are located in 3 and 4 each in the closed state SZ. In the closed state SZ, the two clamping elements 33 of the clamping units 32a and 32b also at least partially cover the opening region 16 of the housing body 10 in such a way that the vehicle battery 120 held in the receiving space 13 is held at least partially by the clamping elements 33 along the vertical axis HA in a form-fitting manner. Furthermore, the vehicle battery 120 is held in a form-fitting manner along the height axis HA by an additional elastically deformable damping element 70, for example a tension spring or an elastically deformable damping layer, arranged in a floor area 17 of the receiving space 13. The two clamping elements 33 embodied as clamping tongs are each mounted in the guide 12 so that they can be slid. The two clamping elements 33 can each be pushed from the closed state SZ into the open state OZ via an insertion force for inserting the vehicle battery 120 into the receiving space 13 . The two clamping elements 33 can be pushed out of the opening region 16 by inserting the vehicle battery 120, ie by the vehicle battery 120 itself. In particular, the vehicle battery 120 is inserted far enough into the receiving space 13 until the two clamping elements 33 mounted for sliding movement move from the open state OZ back into the closed state SZ. For the backward movement, the two clamping elements 33 are each also operatively connected to a restoring element 51a or 51b of a restoring device 50 of the fixing device 100, whereby the transition of the two clamping elements 33 from the closed state SZ to the open state OZ causes the restoring device 50 or the two restoring elements 51a or 51b, e.g to convert the open state OZ back into the closed state SZ. Furthermore, the additional, elastically deformable damping element 70 arranged in the floor area 17 is, in particular, a tension spring for the mechanical damping of the at least one vehicle battery 120 held in the receiving space 13 of the housing body 10 HA is kept free of play or substantially free of play.
