Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric motorcycle cargo box brackets, in particular to a backrest cargo box bracket device for an electric motorcycle. Background Art
[0002] In order to facilitate the placement of items, electric motorcycles or electric vehicles usually also have a trunk rack, which is set at the rear of the vehicle body and is used to fix the trunk. At the same time, some electric vehicles are equipped with a rear backrest to carry passengers and make the passengers more comfortable. The existing rear backrest and the trunk are usually unable to coexist. When the trunk is installed, the trunk is used as the rear backrest, but the trunk is not stable and its structural strength is not high. Some electric motorcycles are beginning to become small and light, and generally do not have a trunk. However, when there is no trunk, its carrying capacity is poor and it can only carry people and cannot carry a certain amount of items. Therefore, improvements are now being made to the rear support bracket of small electric motorcycles, which can not only realize the rear leaning function, but also realize the function of switching to install the cargo box, so as to achieve the function of switching the rear support bracket as needed. This is where small electric motorcycles need to be improved. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0021] Reference Figure 1-6, an electric motorcycle backrest cargo box bracket device, including a bracket box 1 and a pull-out bracket 3, the bracket box 1 is provided with a seat cushion 2 on the upper surface, the pull-out bracket 3 is a long square, the upper surface of the pull-out bracket 3 is symmetrically provided with four outward mounting blocks 5 on both sides, the outward mounting blocks 5 are embedded in the pull-out bracket 3 and the inner end wall of the outward mounting blocks 5 is provided with a pull-out rod 52, the pull-out rod 52 is movably inserted into the active cavity 7 of the pull-out bracket 3, and a first bolt hole 60 and a second bolt hole 6 that penetrates the active cavity 7 are provided on the upper surface of the pull-out bracket 3 at the corresponding position of each active cavity 7, the pull-out rod 52 is provided with a locking bolt hole at the end position, the When the locking bolt hole corresponds to the first bolt hole 60 or the second bolt hole 6, it is locked with a locking bolt 61. The upper surfaces of the four outward mounting blocks 5 are provided with mounting bolt holes 51. Two bracket fixing bolt holes are respectively provided on the two side walls of the bracket box 1 near the tail end position. The two sides of the pulling bracket 3 are respectively provided with a first positioning bolt hole group 31 and a second positioning bolt hole group 32 corresponding to the bracket fixing bolt holes at the outer end position and the inner end position. The tail end of the pulling bracket 3 is movably inserted and fixed from the tail end of the bracket box 1. The tail end of the pulling bracket 3 is installed with a backrest frame 4 and the arc-shaped mounting rod 41 on the backrest frame 4 is fixed to the tail end of the pulling bracket 3.
[0022] When the luggage box is not needed, the pull-out bracket 3 is stored within the bracket box 1, placing the backrest frame 4 (including a backrest board) close to the bracket box 1, acting as a backrest. However, if the luggage box is needed to carry items, the bolts in the bracket fixing bolt holes on both sides of the bracket box 1 are removed, the pull-out bracket 3 is pulled out, and the second positioning bolt hole group 32 is aligned with the bracket fixing bolt holes, and then the bolts are screwed in to secure it. This is done to adjust the extension of the extension mounting block 5 according to the size of the luggage box.
[0023] Mount the bottom of the cargo box on the four extension mounting blocks 5 (bolts are screwed into the mounting bolt holes 51 from inside the cargo box to complete the installation). To install a larger cargo box, adjust the locking bolt holes from aligning with the first bolt holes 60 to align with the second bolt holes 6. Use locking bolts 61 to lock the second bolt holes 6 in place, achieving extension.
[0024] The embedded bolt 11 is screwed into the bracket fixing bolt hole and after the embedded bolt 11 is screwed into the corresponding first positioning bolt hole group 31 or second positioning bolt hole group 32 , the embedded bolt 11 does not protrude outside the bracket fixing bolt hole.
[0025] By using the embedded bolts 11 , after being fixed, the embedded bolts 11 will not be exposed and will not scratch a person sitting on the seat cushion.
[0026] The length of the outward-extending mounting block 5 is 10-12 cm, and the distance between the first bolt hole 60 and the second bolt hole 6 is 6-8 cm. After the locking bolt hole on the pulling rod 52 is pulled from the corresponding first bolt hole 60 to the corresponding second bolt hole 6, the outward-extending mounting block 5 has a length of 3-5 cm placed on the pulling bracket 3.
[0027] Ensure that the outward-stretching mounting block 5 is partially placed on the pull-out bracket 3 regardless of whether it is outward-stretched or not, and has good supporting force. When not outward-stretched, it is completely in the pull-out bracket 3, so that it can be inserted into the bracket box for easy extraction.
[0028] The length of the pull-out bracket 3 is 40-50 cm, and the length of the pull-out bracket 3 drawn out from the bracket box 1 is no more than 4 / 5 of the total length of the pull-out bracket 3. It is ensured that part of the length is inserted into the pull-out bracket for stabilizing the pull-out bracket 3.
[0029] The width of the pull-out bracket 3 is 20-25 cm. After the outward-extending mounting blocks 5 on both sides of the pull-out bracket 3 are pulled outward, the distance between the two corresponding outward-extending mounting blocks 5 is in the range of 35-40 cm.
[0030] When the width between the drawers is 20-25, a 35-45cm cargo box can be installed. For a cargo box for food delivery, the outward-expanding mounting block 5 can be used for installation, and the width of the installed cargo box can reach 50cm.
[0031] The bracket box 1 is a metal box, and the pull-out bracket 3 is a metal plate. It is stable, has a firm structure, and is not easy to fall apart.
[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
