[0023] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0024] An adjustable electric vehicle frame, as shown in Figures 1 to 6 , comprises a frame body 1 and a tail pipe 2, and the tail end of the frame body 1 is provided with two connecting holes 3.

[0025] The tail pipe 2 is rotatably connected with corresponding adjusting pipes 4 at both ends, and the two adjusting pipes 4 are respectively inserted into the corresponding connecting holes 3. The outer side walls of the two adjusting pipes 4 are each provided with a helical guide groove 6, and the helical guide groove 6 is arranged along the axis direction of the adjusting pipe 4. The frame body 1 is detachably connected with two guide pieces 7, and the two guide pieces 7 are respectively inserted into the corresponding helical guide grooves 6. When the adjusting pipe 4 is rotated, the guide piece 7 slides along the helical guide groove 6 to move the adjusting pipe 4 along the axis direction of the connecting hole 3.

[0026] The specific principle is as follows. By rotating the adjusting pipe 4, the rotation of the adjusting pipe 4 will cause the guide piece 7 to slide relative to the helical guide groove 6. The sliding of the guide piece 7 in the helical guide groove 6 will force the adjusting pipe 4 to move along the axis direction of the connecting hole 3, thereby achieving adjustment of the position of the tail pipe 2. With the adjustment of the position of the tail pipe 2, the mounting space at the rear of the frame body 1 is changed, so as to adapt to different specifications of rear cargo racks or tail boxes and meet the diversified use requirements of users.

[0027] It should be noted that the user only needs to rotate the adjusting pipe 4 to complete the adjustment of the position of the tail pipe 2, and the operation process is simple and fast. The adjustment of the position of the tail pipe 2 can be realized only by the cooperation of the guide piece 7 and the helical guide groove 6 on the adjusting pipe 4, and the structure is simple, the manufacturing cost and manufacturing difficulty are low.

[0028] Further, the end of the guide 7 is in the shape of a ball head, so as to reduce the abrasion caused by the relative sliding between the guide 7 and the spiral guide groove 6.

[0029] It needs to be further explained that, in order to avoid misoperation, the tail pipe 2 is provided with two locking members 5 for locking the corresponding adjusting pipe 4, and the adjusting pipe 4 is locked by the locking member 5 to avoid accidental rotation of the adjusting pipe 4, so as to ensure the stability and reliability in normal use.

[0030] The frame body 1 is provided with two mounting holes one 9, and the guide 7 is threadedly connected to the mounting hole one 9, and rotating the guide 7 can make it extend into or out of the spiral guide groove 6.

[0031] The inner side wall of each of the two connecting holes 3 is provided with a limiting step 8, which is used for limiting the adjusting pipe 4 along the axis direction of the connecting hole 3, and specifically, when the guide 7 is aligned with the first end of the spiral guide groove 6, the end of the adjusting pipe 4 abuts against the step surface of the limiting step 8, the limiting step 8 limits the adjusting pipe 4, and the stability of the initial position of the adjusting pipe 4 is ensured, which is convenient for assembly.

[0032] The tail end surface of the frame body 1 is provided with a positioning line one (not shown in the figure), and the outer side wall of the adjusting pipe 4 is provided with a positioning line two (not shown in the figure), when the positioning line one is aligned with the positioning line two, the center axis of the mounting hole one 9 is aligned with the first end of the spiral guide groove 6, so when assembling, the user only needs to align the positioning line two with the positioning line one, so that the mounting hole one 9 is aligned with the first end of the spiral guide groove 6, at this time, the guide 7 is threadedly connected to the mounting hole one 9, so that the guide 7 extends to the first end position of the spiral guide groove 6, which is convenient and fast for assembly.

[0033] It needs to be pointed out that the positioning line one and the positioning line two can be the mark lines drawn by the assembler on the tail end of the frame body 1 and the outer side wall of the adjusting pipe 4 with a marker pen.

[0034] The outer side wall of each of the two adjusting pipes 4 is provided with a plurality of scale lines 12, which are evenly arranged along the length direction of the adjusting pipe 4, and the scale lines 12 are arranged on the adjusting pipe 4, so that the user can intuitively understand the adjustment amount and quickly and accurately adjust the position of the tail pipe 2.

[0035] The outer side wall of the adjusting pipe 4 is provided with an annular groove 13, and the tail pipe 2 is provided with two mounting holes two 14, and the locking member 5 is threadedly connected to the mounting hole two 14, the locking member 5 extends into the annular groove 13, and rotating the locking member 5 can make it abut against the bottom of the annular groove 13, and through the cooperation of the annular groove 13 and the locking member 5, the adjusting pipe 4 can be prevented from being separated from the tail pipe 2 without affecting the normal rotation of the adjusting pipe 4.

[0036] The inner side wall of the tail pipe 2 is provided with a positioning step 15, when the installation hole two 14 is aligned with the annular groove 13, the step surface of the positioning step 15 abuts against the end surface of the adjusting pipe 4, so as to ensure the relative position stability of the adjusting pipe 4 and the tail pipe 2, and also facilitate the quick assembly of the adjusting pipe 4 and the tail pipe 2.

[0037] The assembly principle is as follows:

[0038] Firstly, one end of the adjusting pipe 4 is inserted into the corresponding connecting hole 3 until the end of the adjusting pipe 4 abuts against the step surface of the limiting step 8, then the adjusting pipe 4 is rotated to align the positioning line one with the positioning line two, then the guide piece 7 is screwed into the installation hole one 9 until the guide piece 7 extends into the first section of the spiral guide groove 6, then the other end of the adjusting pipe 4 is inserted into the tail pipe 2 until the end surface of the adjusting pipe 4 abuts against the step surface of the positioning step 15, finally the locking piece 5 is screwed into the installation hole two 14 until the locking piece 5 extends into the annular groove 13 and abuts against the bottom of the annular groove 13.

[0039] It should be noted that before the adjusting pipe 4 is rotated for adjustment, the locking piece 5 needs to be rotated first to move away from the bottom of the annular groove 13, so that the adjusting pipe 4 can be normally rotated, and after the adjustment is completed, the locking piece 5 needs to be rotated again to abut against the bottom of the annular groove 13.

[0040] The specific embodiments described herein are merely illustrative of the spirit of the utility model; the person skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the range defined by the appended claims.
