Description
Technical Field
[0001] This utility model relates to the field of basket lock technology for electric bicycles, and in particular to a safety basket lock for electric bicycles. Background Technology
[0002] Electric bicycles have gradually become a common mode of transportation in people's daily lives. Most electric bicycles sold on the market today have a basket installed on the front for carrying items. These baskets are mostly made of steel lattice or one-piece molded plastic, and also feature a basket cover that flips up and down.
[0003] Existing electric bicycles have a buckle between the basket cover and the basket. After items are placed in the basket, the basket cover is locked in place by the buckle, preventing the basket cover from jumping and making noise during riding and preventing items from popping out of the basket.
[0004] The shortcomings of existing electric bicycle baskets are that they are only secured with clips and generally lack locks. This means that items placed inside the basket are at risk of theft once the user leaves the bicycle. Although a lock can be manually installed on the basket, ordinary mechanical locks require a key to open and close, which is inconvenient for daily use. In short, existing electric bicycle baskets are not easy to lock, have poor security, and are therefore inconvenient to use. Utility Model Content
[0005] The purpose of this utility model is to provide a safety basket lock for electric bicycles, so as to solve the technical problems of electric bicycle baskets being inconvenient to lock, having poor security, and being inconvenient to use.
[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0007] A safety basket lock for electric bicycles includes a lock body and a lock lever. The lock body is fixedly installed on the inner wall of the basket body, and the lock lever is fixedly installed on the basket cover. The lock body has a slot for engaging with the lock lever. The lock body also includes:
[0008] The elastic locking element is disposed inside the slot, and a slot that mates with the elastic locking element is provided on one side of the lock lever.
[0009] An electromagnetic unlocking mechanism is installed inside the lock body and is electrically connected to the power supply of the electric bicycle. When energized, the electromagnetic unlocking mechanism generates a magnetic force to attract the elastic card to disengage from the card slot.
[0010] Preferably, the elastic locking element includes a locking tongue and a limiting spring. A horizontal groove is provided on one side of the inner wall of the slot. The locking tongue is slidably disposed in the horizontal groove. The end of the locking tongue away from the slot is connected to the horizontal groove by the limiting spring. The end of the locking tongue away from the limiting spring is provided with a beveled surface that cooperates with the bottom of the lock lever. The end of the locking tongue away from the limiting spring is used to mate with the slot.
[0011] Preferably, the electromagnetic unlocking mechanism includes an electromagnet, which is fixedly installed inside the lock body and aligned with the bolt. The electromagnet is located on the side of the transverse groove away from the slot, and the bolt is an iron structural component.
[0012] Preferably, the electromagnet is connected in series with the electric bicycle power supply and the electric bicycle ignition lock via wires, and a normally open switch is also connected in series in the circuit between the electromagnet and the electric bicycle power supply.
[0013] Preferably, a sliding top block is slidably fitted inside the slot, and the position of the sliding top block is lower than the position of the locking tongue. A support spring is connected between the sliding top block and the bottom of the slot.
[0014] Preferably, the latch is a square bar, and the transverse groove is a square groove.
[0015] Preferably, the bottom end of the lock lever is a flat end.
[0016] Preferably, the bottom end of the lock lever is a spherical end.
[0017] Preferably, the lock lever is fixedly connected to the basket cover by bolts, and the lock body is fixedly connected to the basket body by bolts.
[0018] Preferably, the lock lever is welded to the basket cover, and the lock body is welded to the basket body.
[0019] The beneficial effects of this utility model are:
[0020] 1. This utility model supplies power to the basket lock via the electric bicycle's power supply. The basket lock can only be unlocked by pressing the normally open switch when the electric bicycle's ignition lock is turned on. It cannot be unlocked when the electric bicycle is powered off, thus ensuring that only the person who controls the electric bicycle key can unlock and use it normally, guaranteeing the safety and anti-theft of the basket lock.
[0021] 2. When locking the basket, this utility model only requires rotating and closing the basket cover, causing the basket cover to rotate and engage the lock lever in the slot on the lock body. This engages with the elastically set lock tongue, ultimately locking the lock tongue into the slot on the lock lever, achieving quick locking. When unlocking is needed, simply press the normally open switch while the electric bicycle is powered on. This causes the electromagnet to electromagnetically attract the lock tongue away from the slot, and the sliding top block and support spring work together to push and unlock quickly. The operation is convenient and effective. Attached Figure Description

[0034] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0035] like Figures 1-10 As shown, a safety basket lock for electric bicycles is used to install inside the basket of an electric bicycle. The existing basket of an electric bicycle is divided into a basket body 14 and a basket cover 15. The basket body 14 is fixedly installed at the front of the electric bicycle. The basket cover 15 is movably connected to the basket body 14 by a hinge and is opened or closed by rotation. The basket lock includes a lock body 1 and a lock lever 2. The lock body 1 is a block in shape and is fixedly installed on the inner wall of the basket body 14, specifically at the upper front side of the basket body 14. The lock lever 2 is used to be fixedly installed on the basket cover 15, specifically located on the lower front edge of the basket cover 15. The lock body 1 is provided with a slot 3 for docking with the lock lever 2. It should be noted that the width of the slot 3 is greater than the width of the lock lever 2 to ensure that the lock lever 2 can be rotatably inserted into the slot 3. The basket lock also includes an elastic locking element and an electromagnetic unlocking mechanism. The elastic locking element is located inside the slot 3. A slot 4 that cooperates with the elastic locking element is opened on one side of the lock lever 2. When the lock lever 2 is inserted into the slot 3, the elastic locking element is locked into the slot 4 by its elastic force to achieve locking.
[0036] The electromagnetic unlocking mechanism is located inside the lock body 1 and is electrically connected to the electric bicycle power supply 16. The elastic card is a magnetic card. When the electromagnetic unlocking mechanism is powered on, it generates a magnetic force to attract the elastic card to disengage from the card slot 4, thus completing the unlocking.
[0037] In some specific implementation plans, such as Figure 4 and Figure 5 As shown, the elastic locking element includes a locking tongue 5 and a limiting spring 9. A transverse groove 10 is provided on one side of the inner wall of the slot 3. The locking tongue 5 is slidably disposed in the transverse groove 10. The end of the locking tongue 5 away from the slot 3 is connected to the transverse groove 10 by the limiting spring 9. The limiting spring 9 is compressible. When the limiting spring 9 is in the initial state, the end of the locking tongue 5 away from the limiting spring 9 is exposed outside the transverse groove 10 and is located inside the slot 3. The end of the locking tongue 5 away from the limiting spring 9 is provided with a beveled surface 6 that cooperates with the bottom of the lock lever 2. The end of the locking tongue 5 away from the limiting spring 9 is used to cooperate and dock with the slot 4.
[0038] It should be noted that the end of the latch 5 that is used to mate with the slot 4 is on the rotation trajectory of the lock lever 2; and the width of the latch 5 is smaller than the width of the lock lever 2, so as to ensure that when the bottom of the lock lever 2 rotates down, it is pressed against the beveled surface 6 at the end of the latch 5.
[0039] When the basket cover 15 rotates onto the basket body 14, the locking lever 2 deflects with the basket cover 15 and is eventually inserted into the slot 3. During the insertion process, the bottom of the locking lever 2 presses against the beveled surface 6 at the end of the latch 5, thereby generating a lateral force on the latch 5 and pushing it to slide into the transverse groove 10. During this process, the limiting spring 9 is compressed to generate a rebound force. After the latch 5 is squeezed into the transverse groove 10, the locking lever 2 continues to descend. When the end of the latch 5 coincides with the slot 4 on the locking lever 2, the latch 5 is ejected into the slot 4 under the rebound force of the limiting spring 9, thus achieving locking.
[0040] In some specific implementation plans, such as Figure 9 As shown, the slot 4 is provided through the lock lever 2.
[0041] In other specific implementation schemes, such as Figure 10 As shown, the slot 4 is set in the form of a notch on the lock lever 2.
[0042] In some specific implementation plans, combined with Figures 5 to 7 As shown, the electromagnetic unlocking mechanism includes an electromagnet 11, which is fixedly installed inside the lock body 1. The space where the electromagnet 11 is located is connected to the space where the latch 5 is located, and the two are aligned. The electromagnet 11 is located on the side of the transverse groove 10 away from the slot 3. Specifically, a mounting cavity can be set on the side of the transverse groove 10 away from the slot 3, and the electromagnet 11 can be fixedly installed in the mounting cavity. An opening is set on the side wall of the lock body 1 to communicate with the mounting cavity, so as to facilitate the maintenance of the electromagnet 11. The latch 5 is an iron structural component.
[0043] When unlocking is required, power is supplied to the electromagnet 11, which generates magnetic force to attract the bolt 5 to slide into the transverse groove 10 and compress the limiting spring 9, thus separating the bolt 5 from the groove 4 on the lock lever 2.
[0044] In some specific implementation schemes, in order to facilitate effective control of the operation of electromagnet 11, such as Figure 8 As shown, the electromagnet 11 is connected in series with the electric bicycle power supply 16 and the electric bicycle ignition lock 13 via wires. A normally open switch 12 is also connected in series in the circuit between the electromagnet 11 and the electric bicycle power supply 16.
[0045] It should be noted that the normally open switch 12 is a push-button switch. When pressed, the circuit is energized, and when released, the circuit is disconnected. It can be installed on the control panel or handlebars of the electric bicycle. The wire connecting the electromagnet 11 and the electric bicycle power supply 16 runs along the upper or lower edge of the basket body 14.
[0046] After the basket cover 15 is locked onto the basket body 14, the user turns off the electric bicycle ignition lock 13 and removes the key and walks away. The circuit of the electromagnet 11 is then disconnected, and the lock tongue 5 cannot be retracted into the transverse groove 10 to unlock the bicycle. Only when the user opens the electric bicycle ignition lock 13 with the key and then presses the normally open switch 12 can the electromagnet 11 be energized to generate magnetic force and unlock the bicycle.
[0047] In some specific implementations, to facilitate the user's easy opening of the basket cover 15 by pressing the normally open switch 12 once, such as... Figure 5 As shown, a sliding top block 7 is provided inside the slot 3 in a sliding fit, and the position of the sliding top block 7 is lower than the position of the locking tongue 5. A compressible support spring 8 is connected between the sliding top block 7 and the bottom of the slot 3.
[0048] When the lock lever 2 rotates and engages with the slot 3, it first presses the bolt 5, causing it to slide into the transverse groove 10. Then, as the lock lever 2 continues to descend, its bottom presses against the sliding block 7, causing it to slide down the slot 3 and compress the support spring 8. This generates a rebound force in the support spring 8. When the lock lever 2 is fully engaged, the bolt 5 is inserted into the slot 4, achieving locking. When the bolt 5 is retracted into the transverse groove 10, achieving unlocking, the support spring 8 releases its rebound force, and the sliding block 7 quickly pushes the lock lever 2 upward. Thus, when unlocking, the user only needs to press the normally open switch 12 once, without needing to press it continuously for a long time, to effectively complete the unlocking process.
[0049] In some specific implementations, in order to prevent the locking tongue 5 from deflecting during the lateral sliding process, which would prevent the beveled surface 6 from facing upwards, the locking tongue 5 can be set as a square bar, and the transverse groove 10 can be a square groove. The two work together to ensure that the locking tongue 5 can only slide laterally.
[0050] In some specific implementation plans, such as Figure 2 As shown, the bottom end of the lock lever 2 is a flat end.
[0051] In other specific implementation schemes, such as Figure 3 As shown, the bottom end of the lock lever 2 is a spherical end, which facilitates the effective squeezing action of the beveled surface 6 at the end of the lock tongue 5.
[0052] In some specific implementations, both the lock lever 2 and the lock body 1 are provided with screw holes. The lock lever 2 is fixedly connected to the basket cover 15 by bolts, and the lock body 1 is fixedly connected to the basket body 14 by bolts, which facilitates disassembly later. Specifically, a plate can be welded to the corresponding positions of the basket cover 15 and the basket body 14 first, and then screw holes can be machined on the plate before bolt installation and connection.
[0053] In some other specific implementations, the lock lever 2 is welded to the basket cover 15, and the lock body 1 is welded to the basket body 14.
[0054] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:
[0055] When the basket needs to be closed and locked, the basket cover 15 rotates onto the basket body 14. The lock lever 2 deflects with the basket cover 15 and is finally inserted into the slot 3. During the insertion process, the bottom of the lock lever 2 presses against the beveled surface 6 at the end of the latch 5, thereby generating a lateral force on the latch 5 and pushing it to slide into the transverse groove 10. During this process, the limit spring 9 is compressed to generate a rebound force. After the latch 5 is pressed into the transverse groove 10, the lock lever 2 continues to descend, and the bottom of the lock lever 2 presses against the sliding top block 7, causing the sliding top block 7 to slide down along the slot 3 and compress the support spring 8. Finally, when the end of the latch 5 coincides with the slot 4 on the lock lever 2, the latch 5 is ejected into the slot 4 under the rebound force of the limit spring 9, thus achieving locking.
[0056] After the basket is closed, when the electric bicycle rider turns off the electric bicycle ignition lock 13 and removes the key and leaves, it cannot be unlocked, thus ensuring that it effectively prevents theft when the person leaves.
[0057] When unlocking is required, the user opens the electric bicycle ignition lock 13 with the key and then presses the normally open switch 12. The electromagnet 11 is energized to generate magnetic force, which attracts the bolt 5 to slide into the horizontal groove 10 and compresses the limit spring 9. In this way, the bolt 5 separates from the groove 4 on the lock lever 2. When the bolt 5 is in the horizontal groove 10 to unlock, the support spring 8 releases its rebound force and the sliding top block 7 pushes the lock lever 2 upward quickly.
[0058] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
