Technical Field

[0001] This utility model relates to the field of bicycles, and more specifically to a connector for a cargo container and a vehicle. Background Technology

[0002] Bicycles or electric bikes are common means of transportation. To make it easier to carry items, people usually install a container (such as a basket) on the rear rack of bicycles or electric bikes.

[0003] To facilitate the securing of cargo containers to shelves, CN204110224U discloses a novel bicycle basket with a mounting base. This basket features a buckle and a base at the bottom of the basket body. The base has a locking mechanism. The base is secured to a bicycle or electric bicycle shelf, and the buckle is fixed to the bottom of the basket body. In use, pressing the buckle of the basket body into the locking mechanism of the base securely locks the basket body to the base. For disassembly, pushing the unlocking switch manually resets the lock head, aligning the locking groove opening upwards. Pulling up the basket body then detaches the basket from the base.

[0004] Although the locking structure described above can lock and unlock the basket, the mechanism consisting of the buckle and the base is not only complex in structure and costly, but also relatively complicated to install and disassemble. Summary of the Invention

[0005] The purpose of this invention is to provide a connector for cargo containers and vehicles that is easy to install and disassemble and has low cost.

[0006] Connectors for cargo containers and vehicles, including: The first crossbeam has a first guide section on it; The second crossbeam has a second guide section. Multiple longitudinal beams, each of which is clearance-fitted with the first guide portion and the second guide portion, and each longitudinal beam is fixed with a connecting component for connecting the vehicle; Multiple fasteners are used to fasten the first crossbeam to the longitudinal beam and the second crossbeam to the longitudinal beam. A connecting plate is used to connect the cargo container. The two ends of the connecting plate are connected to the first crossbeam and the second crossbeam, respectively.

[0007] In use, the connector, excluding the connecting plate, is fixed to the vehicle's rack. The connecting plate is then secured to the cargo container. When connecting the connecting plate to the first and second crossbeams, one end of the connecting plate is movably connected to the first crossbeam, and the other end engages with a lock mounted on the second crossbeam to secure it. For disassembly, the lock is released, and the connecting plate is then separated from the first and second crossbeams. This invention is not only easy to assemble and disassemble, but also consists of several simple parts, resulting in low cost. Attached Figure Description

Detailed Implementation Example 1

[0019] like Figures 1 to 7 As shown, the connector for the cargo container and the vehicle in this embodiment includes a first crossbeam 1, a second crossbeam 2, multiple longitudinal beams 3, multiple fasteners 5, and a connecting plate 6 for connecting the cargo container A. The following is a detailed description of each part and the relationship between them.

[0020] The first crossbeam 1 is provided with a first guide portion, which includes a first groove 1a. The first crossbeam 1 is provided with a first through hole 1b, which communicates with the first groove 1a. The first groove 1a is located at one end of the first crossbeam 1, and the first through hole 1b is located at the other end of the first crossbeam 1. A first step 1c is provided between the first groove 1a and the first through hole 1b.

[0021] The second crossbeam 2 is provided with a second guide portion, which includes a second groove 2a. The second crossbeam 2 is provided with a second through hole 2b, which communicates with the second groove 2a. The second groove 2a is located at one end of the second crossbeam 2, and the second through hole 2b is located at the other end of the second crossbeam 2. A second step 2c is provided between the second groove 2a and the second through hole 2b.

[0022] Each longitudinal beam 3 is respectively fitted with the first guide portion and the second guide portion with a clearance. In this embodiment, one end of the longitudinal beam 3 is fitted with the first groove 1a with a clearance, and the other end of the longitudinal beam 3 is fitted with the second groove 2a with a clearance. The first crossbeam 1 and the longitudinal beam 3 are fastened together by fasteners 5, and the second crossbeam 2 and the longitudinal beam 3 are fastened together by fasteners 5. Preferably, the fasteners 5 pass through the first through hole 1b and are connected to the longitudinal beam 3, and the fasteners 5 pass through the second through hole 2b and are connected to the longitudinal beam 3.

[0023] In this embodiment, the fastener 5 is preferably a screw. Each longitudinal beam 3 is provided with a first threaded hole 3a0. Some screws pass through the first through hole 1b and are threaded to the first threaded hole 3a0. The heads of these screws are pressed on the first step 1c. Other screws pass through the second through hole 2b and are threaded to the remaining first threaded holes 3a0. The heads of these screws are pressed on the second step 2c.

[0024] Each longitudinal beam 3 is fixed with a connecting component 4 for connecting the vehicle. Preferably, the connecting component 4 is a hook for fastening the vehicle, such as a hook for fastening the bicycle rack. The longitudinal beam 3 and the connecting component 4 are integrally formed. The material of the longitudinal beam 3 and the connecting component 4 is preferably plastic. Therefore, injection molding is preferred to make the longitudinal beam 3 and the connecting component 4 integrally formed.

[0025] The longitudinal beam 3 includes a longitudinal beam body 3a, a first slider 3b, and a second slider 3c. The first slider 3b is fixed to one end of the longitudinal beam body 3a, and the second slider 3c is fixed to the other end of the longitudinal beam body 3a. The first slider 3b is in clearance fit with a first guide part, and the second slider 3c is in clearance fit with a second guide part. Preferably, the first slider 3b is in clearance fit with a first groove 1a, and the second slider 3c is in clearance fit with a second groove 2a. Applying a force to the longitudinal beam 3 causes the first slider 3b to move along the first groove 1a and the second slider 3c to move along the second groove 2a, thereby adjusting the distance between the two longitudinal beams 3 to suit vehicle racks of different widths.

[0026] The first slider 3b and the second slider 3c are both provided with the first threaded hole 3a0. When the first slider 3b and the second slider 3c at both ends of the longitudinal beam 3 move to the required position along the first groove 1a and the second groove 2a respectively, the fasteners 5 are threadedly connected to the first threaded hole 3a0 on the first slider 3b and the second slider 3c respectively, so as to fasten the longitudinal beam 3 to the first crossbeam 1 and the second crossbeam 2 as a whole.

[0027] The longitudinal beam 3 also includes a first guide plate 3d1 and a second guide plate 3d2. The first guide plate 3d1 is arranged on both sides of the first slider 3b, and the first guide plate 3d1 slides against the outer wall of the first crossbeam 1. The second guide plate 3d2 is arranged on both sides of the second slider 3c, and the second guide plate 3d2 slides against the outer wall of the second crossbeam 2. The first guide plate 3d1 enables the first slider 3b to move more linearly, and the second guide plate 3d2 enables the second slider 3c to move more linearly.

[0028] The longitudinal beam 3 also includes a cover plate 3e. The longitudinal beam body 3a has a receiving groove 3f. The cover plate 3e mates with the receiving groove 3f, and the cover plate 3e is fixed to the longitudinal beam body 3a. After the connector is installed on the vehicle, the cover plate 3e is located between the longitudinal beam body 3a and the vehicle's rack. A locator (not shown in the figure) can be installed in the receiving groove 3f. The locator is used to communicate with a smart terminal, such as a smartphone. If a vehicle equipped with the connector of this embodiment is lost, the vehicle can be located using the locator installed in the receiving groove 3f.

[0029] In this embodiment, the container A can be, for example, a basket or a box. The container A is fixed to the connecting plate 6, which can be done by welding, riveting, or screwing. Both ends of the connecting plate 6 are connected to the first crossbeam 1 and the second crossbeam 2, respectively. Preferably, one end of the connecting plate 6 is movably connected to the first crossbeam 1, the second crossbeam 2 is provided with a lock for locking the connecting plate 6, and the other end of the connecting plate 6 is provided with a lock hole 6a, which engages with the lock hole 6a on the connecting plate 6.

[0030] In this embodiment, the first crossbeam 1 is provided with a first hook 1d, and the connecting plate 6 is provided with a first through hole 6b. The first hook 1d passes through the first through hole 6b and fastens the connecting plate 6. The second crossbeam 2 is provided with an assembly groove 2d. The lock includes a handle 7 and a spring 8. The handle 7 cooperates with the assembly groove 2d and is hinged to the second crossbeam 2. The handle 7 is provided with a locking tongue 9. The spring 8 is located in the assembly groove 2d. One end of the spring 8 abuts against the second crossbeam 2, and the other end of the spring 8 abuts against the handle 7, causing the locking tongue 9 to be inserted into the lock hole 6a to lock the connecting plate 6. Pressing the handle 7 causes the locking tongue 9 to exit the lock hole 6a, releasing the lock from locking the connecting plate 6. Then, the connecting plate 6 is separated from the first hook 1d, thereby releasing the connection between the connecting plate 6 and the first crossbeam 1 and the second crossbeam 2.

[0031] In this embodiment, an L-shaped pressure block 2e is provided on the second crossbeam 2, and a second through hole 6c is provided on the connecting plate 6. After the pressure block 2e is engaged with the second through hole 6c, the pressure block 2e presses down on the connecting plate 6. The connecting plate 6 is also provided with a third through hole 6d for the pressure block 2e to pass through. The third through hole 6d is connected to the second through hole 6c, and the width W1 of the third through hole 6d is greater than the width W2 of the second through hole 6c. During installation, the pressure block 2e is first passively passed through the third through hole 6d, and then the connecting plate 6 is moved, so that the pressure block 2e is passively moved along the second through hole 6c. Since a part of the L-shaped pressure block 2e is located above the second through hole 6c, the pressure block 2e presses the connecting plate 6 onto the second crossbeam 2.

[0032] In this embodiment, the user moves the first slider 3b and the second slider 3c on the two longitudinal beams 3 along the first groove 1a and the second groove 2a respectively, so that the connecting parts 4 fixed on the two longitudinal beams 3 clamp the vehicle's rack. The fasteners 5 are connected to the first threaded hole 3a0, and the longitudinal beams 3 are fastened to the first crossbeam 1 and the second crossbeam 2 together by the fasteners 5, thereby fastening a part of the connector to the vehicle's rack. The connecting plate 6 and the container A are fixed together beforehand, pressing down the handle 7. Then, the first hook 1d passively passes through the first through hole 6b on the connecting plate 6, and the pressure block 2e passively passes through the third through hole 6d. Then, the connecting plate 6 is moved so that the first hook 1d latches onto the connecting plate 6, and the pressure block 2e passively moves along the second through hole 6c. Since part of the L-shaped pressure block 2e is located above the second through hole 6c, the pressure block 2e presses the connecting plate 6 onto the second crossbeam 2, releasing the handle 7. Under the elastic force of the spring 8, the handle 7 rotates around the hinge point between the handle 7 and the second crossbeam 2. The locking tongue 9 on the handle 7 enters the locking hole 6a, thus locking the connecting plate 6 to prevent it from moving, thereby preventing the container A from separating from the connector. Example 2

[0033] This utility model is not limited to the above embodiments. For example, the lock can also adopt the following structure: Figures 8 to 10 The lock includes a handle 7, a spring 8, a latch 9, a slot cover 10, a lock cylinder 11, and a transmission assembly 12. The slot cover 10 and the mounting slot 2d are fitted together and fixed to the second crossbeam 2. The slot cover 10 has an opening 10a, and one end of the slot cover 10 has a stop bar 10b. When the lock is in the locked state, there is a gap of less than 1mm between the handle 7 and the stop bar 10b. If an axial force is applied to the transmission assembly at this time, the handle 7 will move a short distance before being blocked by the stop bar 10b and unable to move further. The lower end of the slot cover 10 also has a baffle 10c. The second crossbeam 2 has a slot, and the baffle 10c is inserted into the slot. Screws are used to fasten the second crossbeam 2 and the baffle 10c together.

[0034] One end of the spring 8 engages with the bottom of the mounting groove 2d, and the other end of the spring 8 engages with the locking tongue 9. One end of the locking tongue 9 engages with the opening 10a. In this embodiment, one end of the locking tongue 9 is in clearance engagement with the opening 10a. A clearance hole 2f is provided at the bottom of the mounting groove 2d. The other end of the locking tongue 9 is in clearance engagement with the guide hole 2f. The guide hole 2f guides the locking tongue 9, stabilizing its position. The locking tongue 9 has a first inclined surface 9a for unlocking. In this embodiment, the side wall of the locking tongue 9 has a boss 9b, and the first inclined surface 9a is located on the boss 9b. The locking tongue 9 has a clearance hole 9c for making way when the transmission component moves.

[0035] One end of the handle 7 is a free end for engaging with the stop lever 10b, and the other end of the handle 7 is connected to the lock cylinder 11. When the lock cylinder 11 is turned with a key, the handle 7 rotates with the lock cylinder 11, thereby making the handle 7 and the stop lever 10b in a clearance fit, or moving the handle 7 away from the stop lever 10b.

[0036] The lock cylinder 11 cooperates with the transmission assembly 12. A portion of the transmission assembly is located within the assembly groove 2d. The transmission assembly 12 has a second inclined surface 12a for pressing the first inclined surface 9a. The transmission assembly 12 includes a sleeve 12b and a push rod 12c. One end of the push rod 12c is fixed to the sleeve 12b. The second inclined surface 12a is disposed on the push rod 12c. The lock cylinder 11 cooperates with the sleeve 12b. The other end of the push rod 12c passes through the clearance hole 9c on the lock tongue 9.

[0037] The transmission assembly 12 also includes a limiting plate 12d, which is fixed to the sleeve 12b or the push rod 12c. The limiting plate 12d cooperates with the baffle 10c. By limiting the limiting plate 12d by the baffle 10c, the transmission assembly 12 can be prevented from exiting the assembly slot 2d.

[0038] The lock also includes an end plate 13, which is fixed to the second crossbeam 2 after being fitted with the mounting groove 2d. The end plate 13 is provided with a guide component 13a, and the lock tongue 9 is slidably fitted with the guide component 13a to increase the stability of the lock tongue 9 when it is raised and lowered. The end plate 13 is also provided with a through hole 13b, which makes way for the push rod 12c when the lock is unlocked.

[0039] Figure 10 The state shown is the locked state of the latch 9. When it is necessary to unlock the latch 9 from the connecting plate 6, the key is inserted into the lock cylinder 11 and turned to rotate the lock cylinder 11. The lock cylinder 11 drives the handle 7 to rotate, so that the handle 7 moves away from the stop bar 10b. A pushing force is applied to the handle 7, so that the transmission assembly 12 moves axially as a whole. The push rod 12c presses against the second inclined surface 12a, so that the latch 9 overcomes the elastic force of the spring 8 and moves downward along the opening 10a. The latch 9 exits from the lock hole 6a on the connecting plate 6, thereby unlocking the connecting plate 6.

[0040] If a pulling force is applied to the handle 7, the pressure of the second inclined plane 12a on the first inclined plane 9a is released. Under the action of the spring force of the spring 8, the locking tongue 9 passes through the opening 10a and enters the lock hole 6a, locking the connecting plate 6. By turning the lock cylinder 11 in the opposite direction with the key, the lock cylinder 11 drives the handle 7 to reverse. The handle 7 returns to its original position and forms a clearance fit with the stop bar 10b. The blocking effect of the stop bar 10b on the handle 7 prevents accidental locking.
