Description

Technical Field

[0001] The utility model relates to the field of electric tricycles, in particular to a frame assembly. Background Art

[0002] Electric tricycles are three-wheeled vehicles that use batteries as power and motors as drive to transport goods or people. Different types of electric tricycles use different technical standards due to their different uses. Among them, most passenger-carrying electric tricycles use side-wheel motors and external frames (i.e., the frames are outside the wheels). Electric tricycles with this structure have no large axles, light loads, and fully enclosed carports, making them suitable for home use and for the elderly.

[0003] The use and operation of electric tricycles for passengers are simple, and they are very popular among the elderly and disabled, and have good market prospects. However, the interior space of the common electric tricycles for passengers on the market is small, and the riding comfort is relatively poor; moreover, in order to reduce manufacturing costs, most manufacturers design the frame structure to be not strong enough, especially in the middle part of the electric tricycle. When a collision accident occurs during driving, the frame is very easy to deform, thereby increasing the risk of injury to the driver and passengers. Utility Model Content

[0004] The utility model aims to provide a frame assembly, so as to increase the internal space of the electric tricycle and strengthen the structural strength of the electric tricycle.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a frame assembly, including a chassis and a front baffle frame, a rear baffle frame and two side panel frames respectively connected to the four sides of the chassis, a top cover is connected above the front baffle frame, the rear baffle frame and the side panel frames, front doors and rear doors are provided on the two side panel frames, a front row area is formed between the front door and the front baffle frame, a rear row area is formed between the rear door and the rear baffle frame, and an extension portion is provided between the front door and the rear door, and a plurality of first reinforcing protrusions are provided on the extension portion.

[0006] The beneficial effects of this program are:

[0007] By providing an extension portion between the front door and the rear door on the side panel frame, and providing a plurality of first reinforcing protrusions on the extension portion, the added extension portion can increase the internal space of the electric tricycle while also improving the strength of the structure of the electric tricycle, thereby achieving the purpose of improving the driving safety of the electric tricycle.

[0008] Furthermore, adding a plurality of first reinforcing protrusions can better improve the strength of the extended portion compared to adding a single protrusion.

[0009] Preferably, windshield mounting openings are provided above the front block frame, the rear block frame, the front door, the rear door and the extended portion, and windshields are connected to the windshield mounting openings.

[0010] Preferably, a second reinforcement protrusion is provided below the front door and the rear door.

[0011] Preferably, a plurality of mutually independent bumper grooves are provided at the bottom of the front guard frame.

[0012] Preferably, a square reinforcement protrusion and a V-shaped reinforcement protrusion are provided on the top cover, and the square reinforcement protrusion is located above the extended portion.

[0013] Preferably, a steering wheel mounting frame is connected to the front end of the chassis, and the angle between the steering wheel mounting frame and the vertical direction is 18°.

[0014] The beneficial effects of this program are:

[0015] When the inclination angle of the steering wheel mounting frame is set to 18°, the driving safety of the electric tricycle can be better ensured; if the inclination angle is greater than 18°, the force on the main beam of the frame will increase, and the main beam of the frame is prone to breakage; if the inclination angle is less than 18°, the electric tricycle lacks buffering during forward driving, which will increase the force on the shock absorber and increase the risk of shock absorber damage.

[0021] The following is further described in detail through specific implementation methods:

[0022] The figure marks in the drawings of the specification include: side panel frame 1, front door 11, rear door 12, windshield mounting opening 13, second reinforcement protrusion 14, extension portion 2, first reinforcement protrusion 21, front gear frame 3, bumper groove 31, rear gear frame 4, top cover 5, square reinforcement protrusion 51, V-shaped reinforcement protrusion 51, steering wheel mounting frame 6, frame main beam 7.

[0023] Example 1

[0024] Embodiment 1 is basically as attached Figure 1-4 As shown, it includes a chassis (not shown in the chassis figure) and a front baffle frame 3 welded and fixed to the front end of the chassis, a rear baffle frame fixed to the rear end of the chassis, and two side frame frames 1 fixed to the left and right sides of the chassis. The front baffle frame 3, the rear baffle frame and the upper part of the two side frame frames 1 are welded and fixed with the same top cover 5, thereby providing a complete frame assembly for assembling a closed manned electric tricycle. In this embodiment, the front of the vehicle is the front and the rear of the vehicle is the rear. The middle part of the front of the chassis and the left rear and right rear of the chassis are respectively connected with wheel connecting frames, and the wheel connecting frames are used to connect wheels; accordingly, the front baffle frame 3 and the two side frame frames 1 are reserved with wheel grooves for installing wheels.

[0025] like Figure 1 As shown, the front door 11 and the rear door 12 are installed on the two side panel frames 1. The front row area is formed between the front door 11 and the front frame 3, and the front row area is the driving area; the rear row area is formed between the rear door 12 and the rear frame, and the rear row area is the passenger area. Figure 2 and Figure 3 As shown, a windshield mounting opening 13 is provided above the front frame 3, the rear frame, the front door 11 and the rear door 12. The windshield mounting opening 13 is used to install a windshield. The windshield not only provides a closed environment for the electric tricycle, but also provides an observation window for the driver and passengers and ensures lighting inside the vehicle.

[0026] In order to ensure that the driving area has enough operating space, the existing passenger-carrying electric tricycles are designed with limited space in the rear area, which reduces the comfort level of the rear passengers. Based on this, the present embodiment adds an extension portion 2 to both side panel frames 1. The extension portion 2 is located between the front door 11 and the rear door 12. The width of the added extension portion 2 is the width of the increased riding space in the rear area of ​​the frame. A windshield mounting opening 13 for installing a windshield is also provided above the extension portion 2 to further improve the interior lighting of the electric tricycle and increase its aesthetics. At the same time, a plurality of first reinforcement protrusions 21 are provided below the extension portion 2. The first reinforcement protrusions 21 are provided in an integrated manner. As shown in FIG. Figure 1As shown, in this embodiment, three first reinforcing protrusions 21 are provided, namely, a large protrusion located in the middle and small protrusions located on the upper and lower sides of the large protrusion. The three first reinforcing protrusions 21, one large and two small, increase the strength of the middle structure of the electric tricycle by increasing the thickness of the extension 2, thereby solving the problem of weak strength of the middle structure of the traditional electric tricycle, that is, the additional extension 2 can increase the internal space of the electric tricycle while also improving the strength of the electric tricycle structure, so as to improve the driving safety of the electric tricycle; and adding multiple first reinforcing protrusions 21 can also better improve the strength of the extension 2. In addition, after adding the extension 2, the top plate and the chassis need to be increased by the same length, and when considering the width of the extension 2, the distance between the rear seat backrest and the front seat backrest must not exceed 1.0m to ensure that the design of the electric tricycle meets national standards.

[0027] like Figure 1 As shown, a second reinforcement protrusion 14 is provided below the front door 11 and the rear door 12. The second reinforcement protrusion 14 is added to the side frame 1 to further increase the strength of the overall structure of the frame. In this embodiment, three second reinforcement protrusions 14 are also provided, namely, a large protrusion located in the middle and small protrusions located on both sides of the large protrusion. The three second reinforcement protrusions 14 correspond to the three first reinforcement protrusions 21 one by one, which not only improves the appearance design of the electric tricycle, but also facilitates driving in rainy days, and the side frame 1 drains water smoothly.

[0028] like Figure 2 As shown, a plurality of independent bumper grooves 31 are provided on the bottom of the front frame 3, and the shape of the bumper grooves 31 can be specifically set according to the shape of the bumper configured for the electric tricycle. The bumper grooves 31 provided on the front frame 3 can not only provide a force buffering space for the bumper in an accident collision to reduce the impact force on the entire frame, but also the independent bumper grooves 31 form a plurality of protrusions on the surface below the front frame 3, which can play the same effect as the stiffening ribs to strengthen the structural strength, thereby further improving the strength of the front frame 3 structure and ensuring the driving safety of the electric tricycle.

[0029] like Figure 4 As shown, a square reinforcement protrusion 51 and a V-shaped reinforcement protrusion 51 are integrally formed on the surface of the top cover 5. The square reinforcement protrusion 51 and the V-shaped reinforcement protrusion 51 are also for increasing the strength of the top cover 5 structure, and the design of the protrusion can prevent water from accumulating on the top cover 5 of the electric tricycle. The square reinforcement protrusion 51 is located above the extension 2, and the square reinforcement protrusion 51 further improves the strength of the middle structure of the extended frame, providing a guarantee for increasing the length of the frame. In this embodiment, three V-shaped reinforcement protrusions 51 are evenly spaced, and the additional V-shaped reinforcement protrusions 51 are also adapted to the extended frame to ensure the structural strength of the middle and rear ends of the top cover 5.

[0030] Example 2

[0031] like Figure 5 The frame assembly shown is different from Example 1 in that it also includes a steering wheel mounting frame 6, a frame main beam 7 is welded and fixed to the chassis, the steering wheel mounting frame 6 is obliquely connected to the top of the frame main beam 7, and after installation, the angle between the steering wheel mounting frame 6 and the vertical direction is 18°.

[0032] The steering wheel mounting frame 6 is connected to the shock absorber and the front wheel axle. The steering wheel mounting frame 6 carries the steering wheel of the electric tricycle, so its own tilt angle affects the driving safety of the electric tricycle. After research and testing, when the tilt angle of the steering wheel mounting frame 6 is set to 18°, the driving safety of the electric tricycle can be better guaranteed; if the tilt angle is greater than 18°, the force on the frame main beam 7 becomes greater, and the frame main beam 7 is prone to breakage; if the tilt angle is less than 18°, the electric tricycle lacks buffering during forward driving, which will increase the force on the shock absorber, thereby increasing the risk of shock absorber damage.

[0033] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the technical solution of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
