Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a retractable cargo rack for the rear seat of an electric vehicle. Background Technology

[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle uses a battery as its energy source, converting electrical energy into mechanical energy for movement through components such as a controller and motor. The speed is controlled by adjusting the current. An electric vehicle cargo rack is a device that can be installed on an electric vehicle; when using electric vehicles to carry goods, a cargo rack is often installed at the rear of the vehicle to allow for the carrying of more cargo.

[0003] Existing electric vehicle retractable cargo racks have fixed cargo space and can only accommodate goods of a fixed size. They cannot support oversized items, while undersized items are prone to wobbling inside the rack. This makes it difficult to meet diverse cargo needs, resulting in low space utilization. The fixed space cannot be flexibly adjusted according to the size of the items, and it still occupies a fixed area when empty, causing a waste of space on the electric vehicle's rear seat. It is also difficult to adapt to goods of different sizes, and the extended rack is prone to wobbling when carrying goods, indicating insufficient stability. Utility Model Content

[0004] This invention addresses the limitations of existing retractable cargo racks on electric vehicle rear seats. Due to fixed space, they can only accommodate goods of a fixed size, making it difficult to support oversized items and causing small items to wobble. This results in inefficient space utilization, wasted space when not in use, and difficulty adapting to different sized goods. Furthermore, the extended rack is prone to wobbling and lacks stability when loaded. The technical issues involved providing a retractable cargo rack for the rear seat of an electric vehicle.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides a retractable cargo rack for the rear seat of an electric vehicle, including a placement rack. Two adjustment components are provided on the placement rack, each including a fixing block, a guide rod, and a positioning block. Extension racks are provided on both sides of the placement rack, and fixing blocks are fixedly installed on the extension racks. The fixing blocks are slidably connected to the two guide rods. Side plates are fixedly installed at both ends of the two guide rods, and the top ends of the two side plates are fixedly connected to the placement rack. A fixing groove is provided inside the fixing block, and a connecting plate is slidably connected inside the fixing groove. Positioning blocks and connecting rods are fixedly installed at both ends of the connecting plate, respectively. A pull plate is fixedly installed at one end of each connecting rod, penetrating the extension rack, and a pull ring is fixedly installed on the pull plate.

[0006] In this technical solution, the bottom end of the placement rack is provided with multiple equally spaced positioning slots, and the two positioning blocks can be inserted into the multiple positioning slots.

[0007] In this technical solution, a first spring is sleeved on the outer surface of each of the two connecting rods, and the two ends of the two first springs are respectively fixedly connected to the fixing groove and the connecting plate.

[0008] In this technical solution, the placement rack has four sliding grooves inside, and each of the four sliding grooves is slidably connected to a limiting plate. Two extension plates are fixedly installed on each of the two extension racks, and one end of each of the two extension plates extends into the interior of the sliding groove and is fixedly connected to the limiting plate.

[0009] In this technical solution, the interior of the placement rack is provided with multiple equally spaced movable slots, and movable plates are slidably connected inside the movable slots. Movable rods are fixedly installed at one end of each of the multiple movable plates, and telescopic plates are fixedly installed at one end of each of the multiple movable rods to the outer end of the placement rack.

[0010] In this technical solution, an anti-slip pad is provided on one side of the telescopic plate.

[0011] In this technical solution, a handle groove is provided on the telescopic plate.

[0012] In this technical solution, a second spring is sleeved on the outer surface of each of the multiple movable rods, and the two ends of the multiple second springs are respectively fixedly connected to the movable groove and the movable plate.

[0013] In this technical solution, a support frame is provided at the bottom of the placement rack, and the two ends of the support frame abut against the placement rack and the mounting plate, respectively.

[0014] In this technical solution, two bolts are provided at both ends of the support frame, and the four bolts pass through the support frame and are respectively fixed to the placement frame and the mounting plate.

[0015] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0016] The positive and progressive effects of this utility model are as follows: The aforementioned retractable cargo rack for electric vehicles, through the installation of an adjustment component, allows for the pulling of a pull ring, which in turn pushes the extension rack. The fixing block slides along the guide rod until the extension rack extends to the desired length. After releasing the pull ring, the first spring returns to its original position, and the positioning block inserts into the corresponding positioning slot, completing the positioning of the extension rack. The lateral space of the rack can be flexibly expanded according to the size of the goods, and the extension length of the rack can be flexibly adjusted. The insertion and engagement of the positioning block and the positioning slot ensures that the extension rack does not shake when carrying loads, improving the stability of the load and solving the problems of fixed space and difficulty in adapting to different sizes of goods in traditional racks. When the extension rack moves, the extension plate drives the limiting plate to slide along the slide groove, which not only enhances the stability of the extension rack movement and avoids swaying and tilting, but also forms a lateral limit on the placed goods, preventing the goods from shifting left and right during transportation. It realizes the horizontal and vertical expansion of the carrying space. This space size can be freely switched according to the size of the goods, which can meet the compact placement of small items and also carry large items. It solves the problems of fixed space and poor adaptability of traditional placement racks and improves the versatility of electric vehicles in carrying goods. By pulling the handle slot to move the telescopic plate, and placing the object between the telescopic plate and the shelf, the handle is released. The second spring returns to its original position, pushing the telescopic plate to automatically clamp the object with the anti-slip pad, greatly improving the efficiency of picking up and placing. It is suitable for objects of different sizes and shapes to meet diverse carrying needs. When not in use, the return force of the second spring causes the telescopic plate to stick tightly to the shelf, and the anti-slip pad is in close contact with the surface of the shelf, without protruding outward, thus avoiding taking up extra space on the back seat of the electric vehicle.

[0030] like Figure 1-6 As shown, the retractable cargo rack on the rear seat of the electric vehicle includes a placement rack 1. Two adjustment components are provided on the placement rack 1. Each adjustment component includes a fixing block 11, a guide rod 12, and a positioning block 8. Extension racks 2 are provided on both sides of the placement rack 1. Fixing blocks 11 are fixedly installed on the extension racks 2. The fixing blocks 11 are slidably connected to the two guide rods 12. Side plates 13 are fixedly installed at both ends of the two guide rods 12. The top ends of the two side plates 13 are fixedly connected to the placement rack 1. A fixing groove is provided inside the fixing block 11. A connecting plate 4 is slidably connected inside the fixing groove. Positioning blocks 8 and connecting rods 7 are fixedly installed at both ends of the connecting plate 4, respectively. One end of each connecting rod 7 passes through the extension rack 2 and is fixedly installed with a pull plate 9. A pull ring 6 is fixedly installed on the pull plate 9.

[0031] In this technical solution, the bottom end of the placement rack 1 is provided with multiple equally spaced positioning slots 3, and the two positioning blocks 8 can be inserted into the multiple positioning slots 3.

[0032] In this technical solution, the outer surfaces of the two connecting rods 7 are each fitted with a first spring 5, and the two ends of the two first springs 5 ​​are respectively fixedly connected to the fixing groove and the connecting plate 4.

[0033] In this technical solution, the placement rack 1 has four sliding grooves 25 inside, and each of the four sliding grooves 25 is slidably connected to a limiting plate 19. Each of the two extension racks 2 has two extension plates 24 fixedly installed, and one end of each extension plate 24 extends into the interior of the sliding groove 25 and is fixedly connected to the limiting plate 19.

[0034] In this technical solution, the interior of the placement rack 1 is provided with a plurality of equally spaced movable slots 17, and movable plates are slidably connected inside the movable slots 17. Movable rods 14 are fixedly installed at one end of each of the movable plates, and telescopic plates 16 are fixedly installed at one end of each of the movable rods 14 to the outer end of the placement rack 1.

[0035] In this technical solution, an anti-slip pad 15 is provided on one side of the telescopic plate 16. The anti-slip pad 15 can increase the friction with the goods, prevent the goods from sliding and falling off during transportation, and improve the safety of the load.

[0036] In this technical solution, the telescopic plate 16 is provided with a handle groove 21.

[0037] In this technical solution, a second spring 18 is sleeved on the outer surface of each of the multiple movable rods 14, and the two ends of the multiple second springs 18 are respectively fixedly connected to the movable groove 17 and the movable plate.

[0038] In this technical solution, a support frame 22 is provided at the bottom of the placement rack 1, and the two ends of the support frame 22 abut against the placement rack 1 and the mounting plate 20 respectively.

[0039] In this technical solution, two bolts 23 are provided at both ends of the support frame 22, and the four bolts 23 pass through the support frame 22 and are fixed to the placement frame 1 and the mounting plate 20 respectively.

[0040] In use, pulling the pull ring 6 causes the connecting rod 7 to move via the pull plate 9. The connecting rod 7 then causes the connecting plate 4 to slide within the fixed block 11, disengaging the positioning block 8 from the positioning groove 3 at the bottom of the placement rack 1. Simultaneously, the first spring 5 is compressed, pushing the extension rack 2. The fixed block 11 slides along the guide rod 12 until the extension rack 2 extends to the desired length. Releasing the pull ring 6 resets the first spring 5, and the connecting plate 4 causes the positioning block 8 to insert into the corresponding positioning groove 3, completing the positioning of the extension rack 2. This allows for flexible expansion of the lateral space of the placement rack 1 according to the size of the goods, and flexible adjustment of the extension length of the extension rack 2. When the extension rack 2 moves, the extension plate 24 acts as a limit stop. The plate 19 slides along the slide groove 25, which not only enhances the stability of the extension rack 2 movement and avoids swaying and tilting, but also forms a lateral limit on the placed goods, preventing the goods from shifting left and right during transportation, and realizes the horizontal and vertical bidirectional expansion of the carrying space. This space size can be freely switched according to the size of the goods, which can meet the compact placement of small items and also carry large items. It solves the problem of fixed space and poor adaptability of traditional placement rack 1, and improves the versatility of electric vehicle carrying. The insertion and cooperation of positioning block 8 and positioning groove 3 ensures that the extension rack 2 does not sway when carrying, improves the stability of carrying, and solves the problem of fixed space and difficulty in adapting to different sizes of goods in traditional placement rack 1. If further longitudinal space is needed, pull the handle slot 21 to drive the telescopic plate 16 to slide along the movable slot 17 via the movable rod 14. After placing the object between the telescopic plate 16 and the placement rack 1, release the handle. The second spring 18 returns to its original position and pushes the telescopic plate 16 to drive the anti-slip pad 15 to automatically clamp the object, greatly improving the efficiency of picking up and putting down. It can adapt to objects of different sizes and shapes to meet diverse carrying needs. When not in use, the return force of the second spring 18 drives the telescopic plate 16 to stick tightly to the placement rack 1, and the anti-slip pad 15 is in close contact with the surface of the placement rack 1. The entire structure is completely retracted and does not protrude outward, avoiding taking up extra space on the back seat of the electric vehicle. The placement rack 1 is fixed to the mounting plate 20 via the support frame 22. Bolts 23 pass through the support frame 22 to securely connect the placement rack 1 and the mounting plate 20, ensuring that the placement rack 1 does not loosen during the electric vehicle's operation, distributing the weight of the goods on the rear seat of the electric vehicle, and extending the service life of the device.

[0041] The advantages of this application are: 1. By setting the adjustment component, pulling the pull ring 6 pushes the extension frame 2, and the fixing block 11 slides along the guide rod 12 until the extension frame 2 extends to the required length. After releasing the pull ring 6, the first spring 5 returns to its original position, and the positioning block 8 is inserted into the positioning groove 3 at the corresponding position to complete the positioning of the extension frame 2. The lateral space of the placement rack 1 can be flexibly expanded according to the size of the goods, and the extension length of the extension frame 2 can be flexibly adjusted. The insertion and cooperation between the positioning block 8 and the positioning groove 3 ensures that the extension frame 2 does not shake when carrying loads, improves the stability of the load, and solves the problem that the traditional placement rack 1 has a fixed space and is difficult to adapt to goods of different sizes. 2. When the extension rack 2 moves, the extension plate 24 drives the limiting plate 19 to slide along the slide groove 25, which not only enhances the stability of the movement of the extension rack 2 and avoids shaking and tilting, but also forms a lateral limit on the placed goods, preventing the goods from shifting left and right during transportation, and realizes the horizontal and vertical expansion of the carrying space. This can freely switch the size of the space according to the size of the goods, which can not only meet the compact placement of small items, but also carry large items, solving the problem of fixed space and poor adaptability of traditional placement rack 1, and improving the versatility of electric vehicle carrying. 3. By pulling the handle slot 21 to move the telescopic plate 16, and placing the object between the telescopic plate 16 and the placement rack 1, the handle is released. The second spring 18 returns to its original position and pushes the telescopic plate 16 to automatically clamp the object with the anti-slip pad 15, which greatly improves the efficiency of picking up and putting down objects. It can adapt to objects of different sizes and shapes and meet diverse carrying needs. When not in use, the return force of the second spring 18 causes the telescopic plate 16 to stick tightly to the placement rack 1, and the anti-slip pad 15 is in close contact with the surface of the placement rack 1 and does not protrude outward, thus avoiding taking up extra space on the back seat of the electric vehicle.
