Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle tail boxes, and particularly relates to a rear-mounted tail box for electric vehicles. Background Art

[0002] An electric vehicle, also known as an electric car, is a pure electric motor vehicle powered by a storage battery and driven by an electric motor. In order to facilitate carrying items, an electric vehicle usually has a tail box installed at the rear of the back seat to facilitate carrying items. Therefore, a rear-mounted tail box for electric vehicles is needed.

[0003] For a rear-mounted tail box for electric vehicles (publication number: CN220764573U) disclosed, in order to store items in the tail box and ensure the stability of the items during storage, structures such as a base, a fixed buckle, and an elastic band are fixedly installed in the tail box. However, the base is fixedly installed in the tail box, occupying most of the area inside the tail box. When the base is damaged or adhered with a lot of dust, the user can only violently remove the base or clean the base inside the tail box. This method not only causes damage to the tail box but also makes the adhered dust stick to the inner wall of the tail box again. At the same time, the damaged base occupies a certain space but cannot be effectively utilized, reducing the actual available space inside the tail box. Also, the long-term use of a damaged base may cause other components of the tail box to be more easily damaged. In view of this problem, we propose a rear-mounted tail box for electric vehicles.

[0008] A limiting member, a limiting member for limiting is provided inside the base of the box. This method can prevent a damaged storage seat from staying inside the box, resulting in a reduction in available space.

[0009] Preferably, the limiting member includes: a fixed rod, the fixed rod is fixedly installed on the surface of the positioning frame, and an arc-shaped block is fixedly installed on the surface of the fixed rod. The arc-shaped block can fix the movement of the compression rod.

[0010] Preferably, the fixed rod penetrates through the spherical block and is slidably connected to the spherical block. The surface of the spherical block is fixedly connected to one end of the third spring, and the other end of the third spring is fixedly installed on the surface of the fixed rod. When the spherical block is abutted, it can move inside the fixed rod under the support of the third spring.

[0011] Preferably, the driven assembly includes: a cross bar, the cross bar is fixedly installed on the surface of the moving plate, the surface of the cross bar is hinged to a limiting rod, one side of the torsion spring is fixedly connected to the surface of the limiting rod, the other side of the torsion spring is fixedly installed on the surface of the cross bar, and a clamping block is fixedly installed on the surface of the cross bar. When the moving plate moves, the cross bar can slide inside the circular plate.

[0012] Preferably, the cross bar penetrates through the circular plate, and through holes are provided on the surface of the circular plate. The arrangement of the through holes can limit the movement of the cross bar.

[0013] Preferably, one end of a connecting rod is fixedly connected to the surface of the circular plate, and the other end of the connecting rod is fixedly installed on the surface of the cylinder. When the cylinder rotates, the connecting rod can drive the circular plate to rotate synchronously.

[0015] Compared with the prior art, the present utility model provides a rear-mounted tail box for an electric vehicle, having the following

[0016] Beneficial effects:

[0017] 1. The rear-mounted tail box of the battery vehicle is provided with a control component. The pressure rod is pressed into the box seat. The moving rod connected in the pressure rod is forced to slide on the surface of the ball block. When the ball block hits the cross section of the moving rod, the moving rod is forced to slide in the pressure rod. When the moving rod moves to the bottom of the ball block, it will hit the surface of the fixed rod supported by the spring three to slide. When the ball block slides to the bottom of the arc block, the moving rod loses its restriction and bounces up under the support of the spring two. It is no longer restricted by the arc block. Then, the moving plate fixed at the bottom of the pressure rod can bounce up under the support of the spring one. The clamping rod fixed on the surface of the moving plate is moved out of the hole. Then, the fixation of the positioning block and the storage seat can be released. Then, the storage seat can be pulled out of the box body for replacement and cleaning. This method can prevent the damaged storage seat from staying in the box body, resulting in a reduction in available space.

[0018] 2. The rear-mounted tail box of the electric vehicle is provided with a driven component. When the moving plate moves, the cross bar fixed on the surface of the moving plate moves laterally synchronously. When the limit rod hinged on the surface of the cross bar hits the surface of the through hole, it will be folded under the support of the torsion spring and moved out of the through hole. After moving out, the limit rod pops up under the support of the torsion spring and limits the popping up of the cross bar in the circular plate through the card block. This method can perform secondary restrictions on the fixation of the storage seat, thereby ensuring the stability of the storage seat placed in the box. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0026] As Figures 1-6 shown, the present utility model provides a technical solution: a rear-mounted tail box for an electric vehicle, including a box body 1 and a storage seat 4. The surface of the box body 1 is hinged to a box cover 2. The bottom of the box body 1 is fixedly installed with a box base 3. An elastic band 5 is arranged on the surface of the storage seat 4. A positioning block 6 is fixedly installed at the bottom of the storage seat 4. A hole 7 is formed on the surface of the positioning block 6. A positioning frame 10 is fixedly installed in the box base 3. A control component 8 and a driven component 9 are arranged in the box base 3. The control component 8 includes: a clamping rod 81, a moving plate 82, a first spring 83, a pressing rod 84, a moving rod 85, a second spring 86, and a limiting part 87.

[0027] The clamping rod 81 passes through the positioning frame 10 and is slidably connected to the positioning frame 10. A moving plate 82 is fixedly installed on the surface of the clamping rod 81. One end of a first spring 83 is fixedly connected to the surface of the moving plate 82, and the other end of the first spring 83 is fixedly installed on the surface of the positioning frame 10. The surface of the pressing rod 84 is fixedly connected to the surface of the moving plate 82. The pressing rod 84 passes through the box base 3 and is slidably connected to the box base 3. The pressing rod 84 is penetrated by the moving rod 85 and is slidably connected to the moving rod 85. One end of a second spring 86 is fixedly connected to the surface of the moving rod 85, and the other end of the second spring 86 is fixedly installed on the surface of the pressing rod 84. A limiting part 87 for limiting is arranged in the box base 3. When the moving rod 85 loses the limitation and bounces under the support of the second spring 86 and is no longer restricted by the arc-shaped block 872, the moving plate 82 fixed to the bottom of the pressing rod 84 can bounce under the support of the first spring 83. The clamping rod 81 fixed to the surface of the moving plate 82 moves out of the hole 7, so that the fixation of the positioning block 6 and the storage seat 4 can be released, and the storage seat 4 can be pulled out of the box body 1 for replacement and cleaning. This method can prevent the damaged storage seat 4 from staying in the box body 1, resulting in a reduction in the available space.

[0028] The limiting member 87 includes: a fixed rod 871 fixedly installed on the surface of the positioning frame 10. An arc block 872 is fixedly installed on the surface of the fixed rod 871, and the arc block 872 can fix the movement of the pressing rod 84. The fixed rod 871 penetrates through the spherical block 873 and is slidably connected to the spherical block 873. One end of a third spring 874 is fixedly connected to the surface of the spherical block 873, and the other end of the third spring 874 is fixedly installed on the surface of the fixed rod 871. When the spherical block 873 is abutted, it can move within the fixed rod 871 under the support of the third spring 874. The driven assembly 9 includes: a cross bar 91 fixedly installed on the surface of the moving plate 82. The surface of the cross bar 91 is hinged to a limiting rod 92. One side of a torsion spring 93 is fixedly connected to the surface of the limiting rod 92, and the other side of the torsion spring 93 is fixedly installed on the surface of the cross bar 91. A clamping block 94 is fixedly installed on the surface of the cross bar 91. When the moving plate 82 moves, the cross bar 91 can slide within the circular plate 95. The cross bar 91 penetrates through the circular plate 95, and through holes 96 are formed on the surface of the circular plate 95. The arrangement of the through holes 96 can limit the movement of the cross bar 91. One end of a connecting rod 97 is fixedly connected to the surface of the circular plate 95, and the other end of the connecting rod 97 is fixedly installed on the surface of a cylinder 98. When the cylinder 98 rotates, the connecting rod 97 can drive the circular plate 95 to rotate synchronously. The cylinder 98 penetrates through the box seat 3 and is rotatably connected to the box seat 3. One end of a volute spring 99 is fixedly connected to the surface of the box seat 3, and the other end of the volute spring 99 is fixedly installed on the surface of the cylinder 98. When the cylinder 98 loses the force for rotation, it can reverse under the support of the volute spring 99.

[0029] In the present utility model, during use, the box cover 2 is opened, and the items to be stored are placed on the surface of the storage seat 4. After placement, the elastic band 5 is used to fix the items to prevent them from falling during jolting. When the storage seat 4 is damaged or needs to be cleaned and replaced, the cylinder 98 is rotated on the surface of the box seat 3. The connecting rod 97 fixed on the surface of the cylinder 98 can drive the circular plate 95 to rotate synchronously. After the circular plate 95 rotates, the through hole 96 will be parallel to the limiting rod 92. After parallelism, the force of rotation is maintained, and the pressing rod 84 is pressed into the box seat 3. The moving rod 85 connected to the surface of the pressing rod 84 slides on the surface of the ball block 873 under force. When the ball block 873 abuts against the section of the moving rod 85, the moving rod 85 slides inside the pressing rod 84 under force. When the moving rod 85 moves to the bottom of the ball block 873, it will abut against the ball block 873 and slide on the surface of the fixed rod 871 supported by the spring three 874. When the ball block 873 slides to the bottom of the arc block 872, the moving rod 85 loses its restriction and bounces under the support of the spring two 86 and is no longer restricted by the arc block 872. Then, the moving plate 82 fixed at the bottom of the pressing rod 84 can bounce under the support of the spring one 83, and the clamping rod 81 fixed on the surface of the moving plate 82 is removed from the hole 7, so that the fixing of the positioning block 6 and the storage seat 4 can be released, and the storage seat 4 can be pulled out of the box body 1 for replacement and cleaning. This method can prevent the damaged storage seat 4 from staying in the box body 1, resulting in a reduction in available space. After cleaning or inserting a new storage seat 4 into the box body 1, the positioning block 6 enters the positioning frame 10 for preliminary fixing. When fixing, the pressing rod 84 is pressed into the box seat 3. The moving plate 82 fixed on the surface of the pressing rod 84 can move under the support of the spring one 83. The clamping rod 81 fixed on the surface of the moving plate 82 slides in the positioning frame 10 and is clamped into the hole 7. At the same time, when the moving rod 85 abuts against the surface of the arc block 872, it slides inside the pressing rod 84 under force. When the moving rod 85 no longer abuts against the arc block 872, it will bounce under the support of the spring two 86 and be stuck at the bottom of the arc block 872 to complete the fixing of the positioning block 6. When the moving plate 82 moves, the cross bar 91 can slide in the through hole 96. When the through hole 96 abuts against the surface of the limiting rod 92, the limiting rod 92 is folded under the support of the torsion spring 93 and removed from the through hole 96. After removal, the limiting rod 92 bounces under the support of the torsion spring 93, and the cross bar 91 is restricted from bouncing in the circular plate 95 by the clamping block 94. This method can perform secondary restriction on the fixing of the storage seat 4 to ensure the stability of the storage seat 4 placed in the box body 1.

[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
