[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] Please refer to the following Figures 1 to 5 The frame assembly and the mobility scooter having the frame assembly according to the embodiment of the utility model are described.

[0030] like Figures 1 to 5 As shown, the frame assembly according to the embodiment of the utility model comprises: a frame 1, a battery compartment 2, a pedal component 3 and a side guard plate 4. The battery compartment 2 is mounted on the frame 1, the pedal component 3 is located on the upper side of the battery compartment 2 and connected to the frame 1, and the side guard plate 4 is arranged in the width direction of the frame 1 (such as Figure 1 On one side of the left-right direction), the lower end of the side guard plate 4 is connected to at least one of the battery compartment 2 and the frame 1, and the upper end of the side guard plate 4 is connected to the pedal component 3.

[0031] It is understandable that the lower end of the side guard plate 4 can be connected to the frame 1 or the battery compartment 2. Alternatively, the lower end of the side guard plate 4 is connected to both the frame 1 and the battery compartment 2.

[0032] According to the frame assembly of the embodiment of the utility model, the side guard plate 4 is arranged on one side of the width direction of the frame 1, and the lower end of the side guard plate 4 is connected to the battery compartment 2, and the upper end of the side guard plate 4 is connected to the pedal component 3. Therefore, the pedal component 3, the frame 1 and the battery compartment 2 can be fixed by the side guard plate 4, thereby improving the overall structural strength of the frame assembly, and making the anti-torsion performance and driving stability of the frame assembly better, and the side of the frame 1 can be protected by the side guard plate 4, thereby improving the anti-collision ability of the frame assembly.

[0033] Alternatively, if Figure 1 and Figure 3 As shown, the side guard plate 4 has a shielding portion 45, which is located below the frame 1 and is arranged on one side of the battery compartment 2 along the width direction of the frame 1. It can be understood that the shielding portion 45 can protect the side wall of the battery compartment 2 to reduce the risk of damage to the battery inside the battery compartment 2 when the battery compartment 2 collides, thereby improving the safety performance of the mobility scooter.

[0034] Specifically, Figure 5 As shown, the frame 1 is provided with an ear seat 11, which extends downward and is connected to the shielding portion 45. It can be understood that the shielding portion 45 is connected to the frame 1 through the ear seat 11, and when the side guard plate 4 is hit, the side guard plate 4 can transfer the pressure to the frame 1 through the shielding portion 45 and the ear seat 11. Compared with the solution of connecting the shielding portion 45 to the battery compartment 2, the present application can reduce the probability of transmitting the collision force to the battery compartment 2, so as to improve the reliability of the battery operation.

[0035] Alternatively, if Figure 1 As shown, the side guard plate 4 includes a front side guard plate 41 and a rear side guard plate 42, and the front side guard plate 41 and the rear side guard plate 42 are arranged at intervals along the front-to-back direction of the frame 1, and the front side guard plate 41 covers at least a portion of the front side of the frame 1, and the rear side guard plate 42 covers at least a portion of the rear side of the frame 1. It can be understood that the front side guard plate 41 and the rear side guard plate 42 are spaced apart by a preset distance along the front-to-back direction so as to expose a part of the longitudinal beam structure of the frame 1. Since the front side guard plate 41 covers at least a portion of the front side of the frame 1, and the rear side guard plate 42 covers at least a portion of the rear side of the frame 1, the key positions of the frame 1 (i.e., the front and rear ends of the frame 1) that are prone to collision can be protected, and the consumables of the side guard plate 4 can be saved, and the integrity of the frame assembly is better and the appearance is beautiful.

[0036] In the example of the present application, the front side guard plate 41 and the rear side guard plate 42 are both two pieces, that is, the two front side guard plates 41 are symmetrically arranged at the front end of the frame 1, and the two rear side guard plates 42 are symmetrically arranged at the rear end of the frame 1.

[0037] Alternatively, if Figures 3 to 5As shown, at least one of the front side guard plate 41 and the rear side guard plate 42 includes an inner plate 43 and an outer plate 44. For example, the front side guard plate 41 is a double-layer structure of "inner plate 43 + outer plate 44". For another example, the rear side guard plate 42 is a double-layer structure of "inner plate 43 + outer plate 44". In the example of the present application, both the front side guard plate 41 and the rear side guard plate 42 are double-layer structures of "inner plate 43 + outer plate 44".

[0038] The inner plate 43 is provided with a first mounting position 431 and a second mounting position 432. The first mounting position 431 is connected to the ear seat 11, and the second mounting position 432 is connected to the pedal component 3. The outer plate 44 is arranged on the side of the inner plate 43 away from the frame 1 along the width direction of the frame 1. It can be understood that the first mounting position 431 and the second mounting position 432 can be one or more. The inner plate 43 is connected to the frame 1 through the first mounting position 431, and is connected to the pedal component 3 through the second mounting position 432. The outer plate 44 is installed on the outer side of the inner plate 43. On the one hand, the outer plate 44 can shield the first mounting position 431 and the second mounting position 432 of the inner plate 43. On the other hand, the double-layer structure of the front side guard plate 41 and the rear side guard plate 42 can improve the structural strength of the side guard plate 4. In addition, when the outer surface of the side guard plate 4 is worn or bumped, only the outer plate 44 can be replaced, thereby reducing the maintenance cost of the frame assembly.

[0039] In the example of the present application, the first mounting position 431 and the second mounting position 432 are both screw mounting positions, and the inner plate 43 and the outer plate 44 are connected by screws. It can be understood that the screw mounting position is a screw hole or a screw groove, and the inner plate 43 is connected to the pedal component 3 and the frame 1 by screws. This makes it easy to install and remove the inner plate 43 and the outer plate 44, and the side guard plate 4 is more secure after installation.

[0040] In order to improve the structural strength of the side guard plate 4, reinforcing ribs 46 are provided on at least one of the inner plate 43 and the outer plate 44. For example, reinforcing ribs 46 are provided on the inner plate 43. For another example, reinforcing ribs 46 are provided on the outer plate 44. Alternatively, reinforcing ribs 46 are provided on both the inner plate 43 and the outer plate 44, and the reinforcing ribs 46 are arranged on the inner plate 43 and the outer plate 44 in a crisscross manner.

[0041] In the example of this application, Figure 3 and Figure 4 As shown, the reinforcing rib 46 is a honeycomb structure, and the reinforcing rib 46 is arranged on the side of the inner panel 43 adjacent to the outer panel 44. Since the reinforcing rib 46 is arranged on the side of the inner panel 43 adjacent to the outer panel 44, when the outer panel 44 covers the inner panel 43, the structure of the reinforcing rib 46 can be hidden, and the reinforcing rib 46 with a honeycomb structure has a higher structural strength and better anti-collision performance.

[0042] Alternatively, if Figure 3 and Figure 5 As shown, at least one of the front side guard plate 41 and the rear side guard plate 42 is provided with an overlap portion 47, and the overlap portion 47 is aligned with the side of the pedal component 3. For example, the front side guard plate 41 and the rear side guard plate 42 are both provided with an overlap portion 47. It can be understood that the overlap portion 47 is aligned with the side of the pedal component 3, so that the docking position of the front side guard plate 41 and the rear side guard plate 42 and the pedal component 3 can be more regular, so that the integrity of the frame assembly is better and the appearance is beautiful.

[0043] In some embodiments, Figure 1 As shown, the pedal component 3 includes a front end plate 31, a pedal 32 and a tail plate 33. The front end plate 31 is arranged at the front end of the pedal 32, and the tail plate 33 is arranged at the rear end of the pedal 32. The front end plate 31 and the tail plate 33 are both higher than the pedal 32. It can be understood that the structure surrounded by the front end plate 31, the pedal 32 and the tail plate 33 is generally in the shape of a boat, and the tail plate 33 can serve as a mudguard for the rear wheel. The front end plate 31 is connected to the riser of the scooter and matches the front end shape of the frame 1. For example, the front end plate 31, the pedal 32 and the tail plate 33 are all plastic parts and are covered on the upper end of the frame 1 by splicing, which can facilitate the processing and manufacturing of the frame assembly and reduce production costs.

[0044] The front side guard plate 41 is provided at one side of the front end plate 31 along the width direction of the vehicle frame 1 and connected to the front end plate 31, and the rear side guard plate 42 is provided at one side of the tail plate 33 along the width direction of the vehicle frame 1 and connected to the tail plate 33. It can be understood that the direction in which the front side guard plate 41 extends upward is substantially the same as the direction in which the front end plate 31 extends, and the direction in which the rear side guard plate 42 extends upward is substantially the same as the direction in which the tail plate 33 extends, thereby making the integrity of the vehicle frame assembly better.

[0045] The walking vehicle of the embodiment of the utility model comprises the frame assembly of the utility model. For example, the walking vehicle is an electric scooter.

[0046] According to the scooter of the embodiment of the utility model, the side guard plate 4 is arranged on one side of the width direction of the frame 1, and the lower end of the side guard plate 4 is connected to the battery compartment 2, and the upper end of the side guard plate 4 is connected to the pedal component 3. Therefore, the pedal component 3, the frame 1 and the battery compartment 2 can be fixed by the side guard plate 4, thereby improving the overall structural strength of the frame assembly, and making the anti-torsion performance and driving stability of the frame assembly better, and the side of the frame 1 can be protected by the side guard plate 4, thereby improving the anti-collision ability of the frame assembly.
