Technical Field

[0001] This utility model relates to the field of tricycle frames, specifically a cage-type frame for an electric tricycle. Background Technology

[0002] The term "tricycle frame" refers to a method for evaluating the properties and various conditions of concrete materials to obtain information such as the quality, strength, hardness, and durability of concrete. In modern engineering construction, its role is increasingly prominent, as the quality of performance directly affects the quality of construction. Testing concrete allows for accurate and effective understanding of its actual performance, comprehensive evaluation and analysis of its overall performance during construction, and provides a basis and reference for formulating and implementing specific quality management technical solutions, controlling construction quality from the source. To facilitate concrete testing, a vibration table is required. The utility model disclosed in application number "CN202021969953.6" as "A Tricycle Frame" provides a tricycle frame belonging to the field of electric tricycle technology. It solves the problem of existing tricycle frames where the seat cushion is fixed to the electric tricycle frame and cannot be adjusted, leading to inconvenience in use. This tricycle frame includes a main frame body, a seat frame body mounted on the main frame body, and an adjustment device between the main frame body and the seat frame body for adjusting the seat frame body to slide forward and backward on the main frame body. This utility model has a reasonable and simple structural design; the distance between the seat frame body and the main frame body is adjustable; it is structurally stable, has a long service life, and is easy to use. However, it also has the following drawbacks: traditional electric vehicle frames do not use a cage-like structure, resulting in poor stability when in use, making them susceptible to wind-induced vibrations; furthermore, the frame itself has weak protective capabilities and cannot adequately protect the internal space from severe impacts.

A trapezoidal front head mechanism 2 is installed on the side wall of the frame head 17.

[0028] In this embodiment: the trapezoidal front vehicle mechanism 2 includes a front vehicle frame 21 disposed on the front surface of the vehicle chassis 11, and a V-shaped frame 22 is provided laterally in the middle of the side wall of the front vehicle frame 21.

[0029] The front frame 21 is assembled together with the V-shaped frame 22 to increase the tightness of the connection between the frame components.

[0030] In this embodiment: a connecting crossbar 23 is installed laterally on the side wall of the V-shaped frame 22, and a side frame 24 is provided on both sides of the connecting crossbar 23.

[0031] The connecting crossbar 23 and the specific side frame 24 are connected and fixed to the connecting crossbar 23, which similarly increases the stability of the front of the vehicle.

[0032] In this embodiment: an arc-shaped fitting piece 25 is provided horizontally at the top center of the side frame 24, a trapezoidal frame 26 is provided at the bottom center of the side frame 24, and a vehicle frame mechanism 3 is provided on both sides of the trapezoidal frame 26.

[0033] The vehicle frame mechanism 3 includes an L-shaped vehicle frame rod 31 installed in the middle of the side wall of the side frame 24.

[0034] In this embodiment: the top center of the L-shaped body rod 31 is provided with an upper support rod 32, the upper support rods 32 are arranged parallel to each other on both sides of the chassis 11, and the surface of the upper support rod 32 is provided with a frame mounting rivet 33, and the bottom side of the upper support rod 32 is provided with a chassis crossbar 34.

[0035] The frame mounting rivets 33 used require the outer skin to be covered, and screws to be driven into the rivet structure to complete the assembly of the outer covering shell with the frame surface.

[0036] In this embodiment: an L-shaped frame 35 is horizontally installed in the middle of the frame crossbar 34, a T-shaped bracket 36 is provided on the side of the L-shaped frame 35, a rear end frame 37 is provided on the side of the T-shaped bracket 36, and a fitting mechanism 4 is horizontally installed in the middle of the bottom end of the rear end frame 37.

[0037] The fitting mechanism 4 includes a rear U-shaped frame 41 installed on the side wall of the rear end frame 37, and a number of mounting plates 42 are provided at the top center of the rear U-shaped frame 41.

[0038] The rear end frame 37 and the rear U-shaped frame 41 are used as a supporting structure assembly.

[0039] In this embodiment: a connecting gasket 43 is provided at the top center of the mounting plate 42, and a bearing rod 44 is provided at the bottom center of the connecting gasket 43.

[0040] The support is achieved by using the surfaces of the fitting bearing rod 44 and the connecting pad 43, and forms a hinge with the rear end frame 37.

[0041] In this embodiment: a connecting pad 43 is attached to the surface of the rear end frame 37, an L-shaped adjusting support rod 45 is provided in the middle of the connecting pad 43, and an adjusting support plate 46 is provided in the middle of the bottom end of the L-shaped adjusting support rod 45.

[0042] The L-shaped adjusting strut 45 and some adjusting plates 46 can be installed continuously.

[0043] In practical use, the first step is to coordinate the support of the chassis 11 and the corresponding load-bearing crossbars 12.

[0044] At this time, the user uses the specific battery box connecting crossbar 13 to expand the battery box. The battery can be placed in the battery box 14 without worrying about damage to the battery under the electric vehicle. The battery box is bound and covered by the outer shell. The battery box connecting crossbar 13 is used to achieve horizontal interconnection according to the structure of the corresponding trapezoidal frame 26. At this time, some specific side frames 24 are horizontally assembled and combined according to the structure of the corresponding front frame 21 to facilitate the transmission of power supply lines.

[0045] Step 2: Secure the outer wall of the frame;

[0046] At this time, the user uses the middle structure of the side frame 24 to achieve lateral binding, and uses the trapezoidal frame 26 to achieve lateral assembly. Based on the lateral support of the front frame 21 on the side of the corresponding battery box 14, the user positions the side frame 24. The trapezoidal frame 26 is used to implement the upper support rod 32 at the rear end as a toughening treatment for the top of the vehicle body and the side door position, so that the vehicle bottom has better wind protection and anti-sway ability when driving in the rain.

[0047] At this point, the user uses the frame structure for fixation, and assembles the vehicle based on the lateral support of the corresponding connecting pads 43 and the side frame crossbars 34. The user then provides support according to the corresponding trapezoidal frame 26 and the arc-shaped support of the upper support rod 32. Based on the wrapping of the specific arc-shaped fitting piece 25, the user ensures the force on the mounting plates 42 on both sides, better distributing the headwind airflow from the front of the vehicle. The streamlined frame structure conforms to the principles of dynamics and reduces air resistance.
