Description

Technical Field

[0001] This application relates to the field of electric vehicle technology, and in particular to an adjustable trunk rack structure. Background Technology

[0002] Electric bicycles, also known as "electric vehicles," are primarily powered by batteries and driven by an electric motor. In today's era where green travel is increasingly popular, electric bicycles have become the preferred mode of transportation for many consumers due to their convenience and environmental friendliness. Electric bicycles often come equipped with a rear storage compartment for riders to store their belongings.

[0003] The fixed structure of common electric vehicle rear racks means that the size of the rear box is fixed during installation, making it difficult to adjust. The fixed structure of the rear rack means that installers need to select the corresponding size of the rear rack based on the size of the rear box. If the rider needs to change the size of the rear box, the rear rack also needs to be replaced. Utility Model Content

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] This application discloses an adjustable trunk rack structure. (Refer to...) Figure 1 The adjustable trunk rack structure includes a rear rack body 1, which includes a mounting frame 11 and a fixing plate 12 welded to the mounting frame 11. The fixing plate 12 is equipped with an adjustment assembly 2, which includes two horizontal blocks 21 and one vertical block 22. The two horizontal blocks 21 are symmetrically arranged and slide laterally on the fixing plate 12. The fixing plate 12 has horizontal grooves 33 for sliding on each of the two horizontal blocks 21, with each groove corresponding to a different horizontal block 21. The horizontal blocks 21 slide along the length of the horizontal grooves 33. The vertical block 22 slides vertically on the fixing plate 12, with its sliding direction perpendicular to the sliding direction of the horizontal blocks 21. The fixing plate 12 has vertical grooves 34 for sliding on the vertical block 22, which slides along the length of the vertical grooves 34 and is located between the two horizontal blocks 21. The two horizontal blocks 21 slide away from or towards each other, and the two horizontal blocks 21 slide away from or towards the vertical block 22. The upper ends of the horizontal blocks 21 and the vertical blocks 22 are both fixed with connecting blocks 31, and connecting holes 32 are provided on the connecting blocks 31.

[0031] Reference Figure 1 , Figure 2 , Figure 3 The fixed plate 12 has a horizontal sliding groove 35 on the side away from the horizontal block 21, which connects to the horizontal groove 33, and the horizontal sliding groove 35 and the horizontal groove 33 correspond one-to-one. The fixed plate 12 has a vertical sliding groove 36 on the side away from the vertical block 22, which connects to the vertical groove 34. The adjustable trunk rack structure also includes a fixing member 4 for limiting the sliding of the horizontal block 21 and the vertical block 22. The fixing member 4 is located in the horizontal sliding groove 35 and the vertical sliding groove 36 respectively. The fixing member 4 includes a slider 41, which is slidably connected in the horizontal sliding groove 35 and the vertical sliding groove 36 respectively. The slider 41 is fixed on the horizontal block 21 or the vertical block 22. The slider 41 in the horizontal sliding groove 35 slides along the length of the horizontal sliding groove 35, and the slider 41 in the vertical sliding groove 36 slides along the length of the vertical sliding groove 36.

[0032] Reference Figure 1 , Figure 2 , Figure 3The fixing component 4 also includes a limiting block 42, which is fixed to the end of the slider 41 away from the fixing plate 12. Two protrusions 51 are fixed on the side of the limiting block 42 closest to the fixing plate 12, with the two protrusions 51 located on both sides of the horizontal groove 33 and the vertical groove 34, respectively. The fixing plate 12 has several positioning grooves 52 for accommodating the protrusions 51. These positioning grooves 52 are arranged along the length of the horizontal sliding groove 35 and the length of the vertical sliding groove 36, and are evenly spaced to facilitate differentiation of the trunk dimensions.

[0033] Reference Figure 2 , Figure 3 , Figure 4 The fixing component 4 also includes a spring 43. A receiving groove 53 is provided at the end of the slider 41 near the limiting block 42. The spring 43 is fixed within the receiving groove 53, with the spring force direction perpendicular to the sliding direction of the slider 41. One end of the spring 43 is fixed to the bottom of the receiving groove 53, and the other end is fixed to the limiting block 42. The spring 43 drives the protrusion 51 to be positioned within the positioning groove 52. A positioning sleeve 6 is fixed to the side of the limiting block 42 near the receiving groove 53, and the positioning sleeve 6 is located within the receiving groove 53, while the spring 43 is also located within the positioning sleeve 6.

[0034] Reference Figure 1 Two positioning blocks 7 are fixed on the fixing plate 12, and the two positioning blocks 7 are symmetrically arranged. Mounting blocks 8 are fixed on both sides of the mounting bracket 11 that are close to each other, and fixing holes 9 are opened on the mounting blocks 8.

[0035] The implementation principle of an adjustable trunk rack structure in this application embodiment is as follows: The installer first installs the rear rack body 1 onto the electric vehicle body through the fixing holes 9. When the trunk needs to be installed, the installer places the trunk on the fixing plate 12, with the end of the trunk abutting against the positioning block 7, ensuring the trunk is placed flat. The installer then pulls up the limiting block 42 on the vertical block 22, causing the protrusion 51 to disengage from the positioning groove 52. Next, the installer pulls the limiting block 42 again, causing the vertical block 22 to slide away from the mounting frame 11. Releasing the limiting block 42 on the vertical block 22 allows the protrusion 51 to be positioned within the positioning groove 52. This is achieved through the connecting hole 32 on the vertical block 22. The first step of fixing the trunk is to pull up the limiting block 42 on the horizontal block 21 so that the protrusion 51 is disengaged from the positioning groove 52. Then, pull up the limiting block 42 on the vertical block 22 so that the horizontal block 21 slides away from the vertical block 22. Release the limiting block 42 on the vertical block 22 so that the protrusion 51 is located in the positioning groove 52. The second step of fixing the trunk is achieved through the connecting hole 32 on the horizontal block 21, so that the trunk is firmly installed. Several positioning grooves are provided so that the vertical block 22 and the horizontal block 21 can be adjusted appropriately according to the size of the trunk. The trunk rack structure can accommodate trunks of more sizes.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
