Description

[0001] The invention relates to the technical field of bicycle stands for parking bicycles. In particular, the invention relates to an electrically adjustable bicycle stand.

[0002] Various types of bicycle stands are known from current technology. Foot-operated rear and center stands, which lock mechanically into place, are the most common for supporting bicycles. A rear stand is a single-legged bicycle stand that attaches to the left chainstay of the frame at the rear wheel. A center stand is a single-legged or double-legged bicycle stand that is mounted below the bottom bracket. Both stands fold backward and lock into place with a spring-loaded mechanism. Current rear stands, for example, provide inadequate support for bicycles, especially when equipped with accessories such as bags, child seats, etc., and particularly when the bicycle is tilted. They only provide support on one side of the bicycle, and the support point is also inconveniently located far behind the center of gravity. The biggest disadvantage of center stands is the very awkward lifting of the bicycle, especially when carrying accessories.The pedal position must be aligned beforehand for successful support. The stability of both stand types is highly dependent on the terrain, for example, bumps or potholes.

[0003] The publication EP 2 236 396 A1 describes a bicycle stand with two support rods, wherein each of the two support rods is rotatably coupled to a central block which is to be attached to a frame of a bicycle or the like, wherein each rod has kinematic means at its pivot point for rotatable coupling with the block which are suitable to transmit the rotation of one rod to the other rod.

[0004] The publication DE 83 10 686 U1 describes a bicycle stand with two support feet which are pivotably connected to a vertically extending mounting base for attaching the bicycle stand to the frame of a bicycle in such a way that they have a smaller distance between them in the non-use position (driving position) than in the use position (parking position).

[0005] Document CN 1 05 966 ​​497 A discloses an intelligent support device for an electric car. The intelligent support device comprises a control system, a drive system, and a transmission support system. The control system includes a single-chip microcomputer. The drive system comprises a front drive motor and a rear drive motor. The transmission support system comprises a front transmission support frame and a rear transmission support frame. The front transmission support frame comprises a front transmission gear, a front transmission leadscrew, a front extendable frame, and universal gears located at the base of the front extendable frame. The front transmission gear is in rotary engagement with a motor shaft of the front drive motor. The axle of the front transmission gear and the front transmission leadscrew are connected to drive the front transmission leadscrew in a rotary motion.The front expandable frame is rotationally fixed to the front transmission leadscrew.

[0006] Document CN 1 04 943 768 A discloses an automatic parking assistance system for theft protection of a two-wheeled electric vehicle. The theft-proof automatic parking assistance system comprises a housing. A supporting transmission assembly is mounted on the housing. A drive unit and a control unit are located within the housing. The supporting transmission assembly includes transmission tubes mounted on the housing. T-shaped lead screws are arranged in the transmission tubes and connected to the inner wall surfaces of the telescopic tubes by plastic nuts in a threaded configuration. The plastic nuts and the transmission tubes are rigidly connected by plastic sliding sleeves in a clamping configuration. Worm gears are located on the sections near the outer wall surfaces of the ends of the telescopic tubes of the transmission tubes.

[0007] Document GB 175 200 A describes a support for bicycles, motorcycles, etc. The device consists of a tube closed at the top with a perforated cap and a rod passing through the cap like a pump. At its lower end, the rod has a metal piston that fits inside the tube. The piston has two or more slots to accommodate the ends of legs hinged to it. The piston has a recess to receive a coil spring, which acts directly or via a bolt against the inner ends of the legs and tends to push the outer ends of the legs apart.

[0008] Document US 683 463 A discloses a bicycle support that can be attached to a bicycle frame to hold the machine in a standing position.

[0009] Document US 570 659 A concerns improvements to devices designed to support bicycles. Its objectives include providing a simple and inexpensive device that can be easily attached to any type of bicycle and that not only serves to keep the bicycle upright when desired, but also assists beginners in learning to ride.

[0010] Document JP 2006-327 221 A discloses a bicycle capable of reliably preventing a fall when stopped and attracting the attention of bystanders through light emission. The bicycle is equipped with a pair of legs rigidly attached to a frame that holds the front wheel. These legs are positioned on either side of the front wheel to rest on the ground, and feature a telescopic mechanism for extending and retracting the legs. Each leg is equipped with a light-emitting device and a power source. The upper end of each leg is attached to a luggage basket mounted at the front of the bicycle.

[0011] Document US 2007 / 0040351A1 discloses a motorcycle anti-tip device featuring telescopic support arms that extend to the ground. The support arms extend automatically when the motorcycle is stationary or moving slowly to prevent it from tipping over. The telescopic support arms can also function as conventional kickstands or be used to lift the motorcycle during maintenance. Alternatively, an airbag can be deployed from under the motorcycle to prevent it from tipping over.

[0012] As the bicycle market has changed in recent years, the rise of e-bikes has led to an increased willingness to buy more expensive products. This, in turn, has led to a greater need for security. Traditional bicycle locks secure a bicycle in its parked position and must be wrapped around an object, such as a lamppost, in the parking area. Successful locking requires that this object be accessible. Especially in large cities, there aren't enough opportunities to stop, particularly for spontaneous bicycle use. This is where internal bicycle locks, such as spoke locks and frame locks, come in, preventing the bicycle from being ridden away. Spoke locks typically block the rear wheel with a metal pin. These particularly compact types of bicycle locks can therefore be considered immobilizers.

[0013] The technical object of the present invention is therefore to provide a bicycle stand which, when supporting the bicycles, on the one hand prevents them from tipping over uneven ground and on inclines, and on the other hand offers additional theft protection.

[0014] This problem is solved by technical devices according to the independent claims. Technically advantageous embodiments are the subject of the dependent claims, the description, and the drawings.

[0015] According to one aspect, the problem according to the invention is solved by an electrically adjustable bicycle stand that can be attached inside or along a down tube of a bicycle, comprising: - a sled, - a threaded rod connected to the slide, - an electric motor drive for driving the threaded rod, configured to move the carriage along one longitudinal direction into a working position and along the opposite longitudinal direction into a non-working position when driving the threaded rod, - two support legs, each connected to the carriage via a joint and lying parallel to each other in the non-use position, wherein the threaded rod (5) runs centrally between the support legs, each support leg being arranged to be unfolded by means of the joint when the carriage is moved into the use position, wherein the joint comprises a kinematic means, - a plurality of frames, designed to accommodate at least the slide, the threaded rod and the electric motor drive, designed to hold the support legs parallel to each other in the non-use position, further designed to hold the slide, the threaded rod and the electric motor drive within a housing or within the down tube of the two-wheeler, - a control unit for controlling the electric motor drive, wherein the control unit is further configured to lock the bicycle stand in the operating position.

[0016] The electrically adjustable bicycle stand described above enhances the stability, safety, and convenience of bicycle stands known from the prior art. The invention combines a bicycle stand with an immobilizer, thereby increasing overall security when parking the bicycle and contributing to theft prevention by preventing unauthorized removal. Stability is increased because the bicycle can be securely supported by the stand even on varying ground conditions. The frame design offers the advantage of a lightweight and compact bicycle stand while maintaining sufficient stability.

[0017] According to the invention, the electric motor drive is a self-locking linear actuator. The self-locking linear actuator ensures that the mechanism locks automatically. This prevents the kickstand from extending unsafely while riding and from retracting into the parking position, thus increasing the safety of the electric kickstand. No motor current is required to hold the kickstand in the correct position. Using a linear actuator also simplifies mounting on the downtube, as it saves space compared to other technical solutions. Furthermore, a linear actuator is less expensive than a hydraulic or pneumatic solution.

[0018] According to the invention, the kinematic means of the joint is an internal torsion spring. The use of torsion springs is very cost-effective. Furthermore, they offer a very lightweight and space-saving way to unfold the legs independently of each other.

[0019] In a technically advantageous embodiment, the control unit includes a device for detecting the motor current of the electric drive. Detecting the motor current offers the advantage that, for example, an increase in motor current can detect obstacles in the path of the bicycle stand, allowing the stand to be switched off for safety reasons. This can also prevent limbs from being trapped. Furthermore, an increase in motor current can signal contact between the bicycle stand and the ground. This is helpful, for example, for calibrating the bicycle stand.

[0020] In a technically advantageous embodiment, the control unit is configured to unlock the bicycle stand in the operating position using an electronic transponder. Electronic transponders can serve as access keys for operating the electrically adjustable bicycle stand. They thus increase safety when operating the bicycle stand and therefore also help prevent unauthorized use.

[0021] In a technically advantageous embodiment, the control unit comprises a GPS module and / or a module for wireless data transmission. Using a GPS module, the position of the two-wheeler can be recorded at any time and, for example, communicated to the owner of the two-wheeler via wireless data transmission.

[0022] In a technically advantageous embodiment, the bicycle stand comprises a housing for receiving at least the slide, the threaded rod, and the electric motor drive, wherein at least two frames are arranged to attach the housing of the bicycle stand to the down tube of the bicycle. An advantage of this design is that bicycles can be retrofitted with the electrically adjustable bicycle stand. All technically relevant components are located within the housing. This protects the components from dirt and reduces abrasive wear. Additionally, the housing serves to unite the components into a single unit.

[0023] In a technically advantageous embodiment, the control unit is housed in the casing of the bicycle stand or in the down tube of the bicycle, or the control unit can be attached to another position on the bicycle. The independent mounting of the control unit allows for the operation of a wide variety of bicycle types.

[0024] In a technically advantageous embodiment, each frame includes an adjustable, prism-like receptacle for attaching the bicycle stand housing to the bicycle's downtube. The advantage here is that the frames can be easily adapted to varying downtube diameters using the adjustable receptacle, and the downtube is securely held in the receptacle. The special design of the receptacle allows it to accommodate a wide variety of bicycle models.

[0025] In a technically advantageous embodiment, the housing is manufactured using injection molding. Stable housings for the bicycle stand can be easily produced using an injection molding process. This also reduces costs in mass production.

[0026] In a technically advantageous embodiment, the housing includes a circumferential labyrinth seal. The labyrinth seal protects the mechanism of the bicycle stand, which is installed inside the housing, from splashing water.

[0027] In a technically advantageous embodiment, the bicycle stand includes a lighting device for illuminating the ground. A lighting device is advantageous because it allows obstacles on the ground to be detected early in the dark.

[0028] According to another aspect, the problem according to the invention is solved by a method for operating an electric two-wheel stand according to one of the preceding claims, comprising the steps: (A) Activating the electrically adjustable bicycle stand using the control unit, (B) Driving the threaded rod by the electric motor drive, wherein the electric motor drive is a self-locking linear actuator, wherein by driving the threaded rod the carriage is moved along a longitudinal direction from a non-use position to a use position, wherein from a certain position the support legs are each unfolded and locked by means of the kinematic means, wherein the kinematic means (9) is an internal torsion spring, wherein the threaded rod is driven until the bicycle stand has reached the use position, (C) Locking the bicycle stand in the operating position by the control unit. By actively triggering the process to move the electrically adjustable bicycle stand into an operating position, unintentional extension can be prevented.

[0029] In a technically advantageous embodiment of the bicycle stand, the method includes the additional step: (D) Unlocking the bicycle stand using an electronic transponder, (E) Initiating a process to move the electrically adjustable bicycle stand into a non-use position by means of the control unit.

[0030] In a technically advantageous embodiment of the bicycle stand, the step of driving the threaded rod by means of the electric motor drive comprises the following additional steps: (B.1) Recording a motor current of the electric motor drive, (B.2) Switching off the electric motor drive when a current limit is reached.

[0031] Switching off the electric motor drive when a current limit is reached serves in particular as a protective function for the mechanics, the electrical system and the user.

[0032] Exemplary embodiments of the invention are shown in the drawings and are described in more detail below. They show: Fig. 1. Perspective views of an electrically adjustable bicycle stand, Fig. 2 perspective views of the system states of the bicycle stand in the non-use position Fig. 2 a) and in operating position Fig. 2 b), Fig. 3 a perspective view of a two-wheeler with a bicycle stand attached to the frame, Fig. 4 schematic views of the bicycle stand when moving the bicycle stand from a non-use position to the use position, Fig. 5 a sectional view of a brace for attaching the bicycle stand, Fig. 6 a perspective view of a housing with labyrinth seal, Fig. 7 different views of a control unit, Fig. 8 a flowchart of a procedure for operating an electrically adjustable bicycle stand.

[0033] Fig. Figure 1 shows two perspective views of an electrically adjustable bicycle stand 2 according to an embodiment of the invention. The bicycle stand 2 comprises a carriage 4, a threaded rod 5 connected to the carriage 4, and an electric motor 6 for driving the threaded rod 5. When the threaded rod 5 is driven, the electric motor 6 is configured to move the carriage 4 along one longitudinal direction into a working position and along the opposite longitudinal direction into a disused position. Similar to aircraft construction, frames 10 serve as a basic structure. The frames 10 serve, firstly, to support the individual components, such as the carriage 4 and the threaded rod 5, and secondly, they can also be used for attachment to the downtube 3 of the bicycle 1. The legs 7 are attached to a joint 8 sprung by internal torsion springs 9.To allow the joint 8 to move freely through the rectangular cutouts in the frames 10, it has exactly the same outer dimensions as the tubes of the carriage 4 and the legs 7. A threaded rod 5 with its counterpart in the carriage 4 is located in the center between the tubes. In a first embodiment of the invention, the bicycle stand 2 is housed in a down tube 3 of a bicycle 1. The frames 10 serve both to accommodate the mechanism and to secure the bicycle stand 2 within the down tube 3. In a further embodiment, the bicycle stand 2 may comprise a housing 11, with the mechanism being housed within the housing 11. Fig. Figure 1 b) shows a perspective view of the bicycle stand 2, with the mechanism housed in the casing 11. The casing 11 can be attached to the down tube 3 of the bicycle 1 by means of ribs 10. For this purpose, each rib 10 has a prism-like, rubberized mount 16. The mount can be adjusted by means of two screws 14 to accommodate different down tube diameters.

[0034] Fig. Figure 2 shows two perspective views of the bicycle stand 2 in a non-use position. Fig. 2 a) shown and in a use position in Fig. 2 b) shown. In the retracted state, the non-used state, the two support legs 7 lie parallel to each other and are held in position by the frames 10. Fig. Figure 2 b) shows the operating position of the bicycle stand 2 in its fully extended state, the operating position. The legs 7 are unfolded and thus secure the bicycle 1 against falling over. For example, the support legs 7 can have a width of 300 mm, which reliably protects the bicycle 2 against falling over.

[0035] Fig. Figure 3 shows a perspective view of a two-wheeled vehicle 1 with a bicycle stand 2 attached to the down tube 3, according to an embodiment of the invention. In the Fig. In the embodiment shown in Figure 3, the bicycle stand 2 is housed in a casing 11. The casing 11 is attached along a down tube 3 of the bicycle 1. For attachment, for example, two of the frames 10 are equipped with adjustable, prism-like mounts 16. In an embodiment of the invention, the electrically adjustable bicycle stand 2 includes a lighting device for illuminating the ground. The lighting device switches on automatically, for example, when the bicycle stand 2 is moved from the unused position to the used position and remains illuminated for a defined period of time.

[0036] Fig. Figure 4 shows schematic views of the bicycle stand 2 during the movement of the bicycle stand 2 from a non-use position to the use position. In the retracted state, in the non-use position in Fig. As shown in Figure 4 a), the two support legs 7 lie parallel to each other within the frames 10. They are held in position by the two front frames 10. The torsion springs 9 in the joint 8 are pre-tensioned in this state. If the user now initiates a process to move the bicycle stand 2 into a working position, the electric motor drive 6 drives the centrally located threaded rod 5, so that the carriage 4 is moved forward, as shown in Figure 4 a). Fig. 4 b) shown. The legs 7 and the slide 4 slide through the frames 10. As soon as the pre-tensioned joint 8 has reached the last frame 10, the legs 7 are freely movable and the pre-tensioned springs 9 relax, as shown in Fig. 4 c) and Fig. 4 d) shown. Now the sled 4 can be moved even further out of the frames 10. This allows any differences in ground height or height differences due to different frame shapes to be compensated for. The maximum compensation distance a is shown in Fig. 4 e). The parking position has now been reached. Since the threaded rod 4 is self-locking, the mechanism is now locked and the electric motor drive 6 can be switched off. Unintentional extension while driving is also impossible due to this self-locking mechanism.

[0037] Fig. Figure 5 shows a top view of a mounting bracket 10. In order to attach the electrically adjustable bicycle stand 2 with its housing 11 to the down tube 3, two brackets 10 with a prism-like, rubberized receptacle 16 are provided in one embodiment. As shown in Fig. As shown in Figure 7, the mount 16 is adjustable by two screws 14 to accommodate variable downtube diameters.

[0038] Fig. Figure 6 shows a perspective view of a housing 11 for an electrically adjustable bicycle stand 2 according to an embodiment of the invention. The housing 11, designed for injection molding, has a circumferential labyrinth seal 17 to protect the mechanism against splashing water. Fig. Figure 8 shows a recess 12, which serves to receive the frames 10. The frames 10 are screwed into the housing 11. In another embodiment, an opening can be provided at the upper housing outlet to connect a cable harness running to the control unit.

[0039] In Fig. Figure 7 shows various views of a control unit 15 for an electrically adjustable bicycle stand 2. In one embodiment of the invention, the control unit 15 can, for example, be housed together with the bicycle stand 2 in a housing 11 of the bicycle stand 2 or within the down tube 3 of the bicycle 1. In another embodiment, a separate control unit 15 can be provided, which has its own power supply, for example via a battery. It is also possible for the power supply to be provided by the battery of, for example, an e-bike. Fig. Figure 7 a) shows a sectional view of a control unit 15 which can, for example, be attached to the handlebars of the bicycle 1. For example, the control unit 15 can be integrated into a bicycle lamp 20, as shown in the perspective view in Fig. Figure 7 b) shows that the control unit 15 is attached to the handlebar via a rubberized clamp 19. Reverse polarity protected, waterproof connectors supply power to the electric motor drive in the housing 11 of the bicycle stand 2 via an insulated cable. The plug contacts also allow the control unit to be quickly removed for battery charging. The electric bicycle stand 2 is operated intuitively. The two system states, operating position and non-operating position, are activated via a release switch 21 on the control unit 15. The electric motor drive 6 continues to operate until a limit switch signals an end position or an increased motor current shuts down the system for safety reasons to prevent injuries. In one embodiment of the invention, an anti-theft device is provided.The anti-theft device can be an immobilizer that locks the electrically adjustable bicycle stand 2 in the operating position. A key system is provided for implementing the immobilizer. This can include an electronic transponder 18, which can be connected to the control unit 15. If the transponder 18 is not connected to the control unit 15 (e.g., inserted into the control unit 15), the electronics are locked and the stand is secured. The electronic transponder 18 can be, for example, an NFC or RFID chip. A personalized NFC chip, for instance, can be provided, which is inserted into a reader slot 24 to unlock the system. Fig. Figure 7 d) shows a perspective sectional drawing of the control unit 15 with an electronic transponder inserted into the read slot 24. Alternatively, the user can use their NFC-enabled smartphone for unlocking. A status LED 23 indicates successful reading of the transponder 18 and the attainment of a specific system state. Due to varying bicycle frame sizes, the bicycle stand 2 must be calibrated once before its first use. During the calibration process, the stand 2 moves into the operating position and uses the mechanisms mentioned above to detect when it has made contact with the ground.

[0040] Fig.Figure 8 shows a flowchart of a method for operating an electrically adjustable bicycle stand 2 described above, according to an embodiment of the invention. The method starts in step S1 with the triggering of a process to move the electrically adjustable bicycle stand 2 into a working position by means of the control unit 15. In step S2, this causes the threaded rod 5 to be driven by the electric motor drive 6, whereby the carriage 4 is moved along a longitudinal direction from a non-working position to a working position by driving the threaded rod 5. From a certain position, the support legs 7 are unfolded and locked by means of the kinematic device 9. The threaded rod 5 is driven until the bicycle stand 2 has reached the working position. In step S3, the bicycle stand 2 is locked in the working position by the control unit 15.Now the bicycle stand 2 is securely positioned on the ground and the bicycle 1 is secured against falling over. Because the bicycle stand 2 is locked in the operating position by the control unit 15, it is no longer possible to move the bicycle stand 2 back to the non-operating position without unlocking it. This provides an effective immobilizer. In step S4, the bicycle stand 2 is unlocked using an electronic transponder 18. Then, in step S5, the process of moving the bicycle stand 2 to the non-operating position can be initiated.

[0041] All features described in connection with individual embodiments of the invention can be provided in different combinations in the object according to the invention in order to simultaneously realize their advantageous effects, even if these have been described for different embodiments.
