Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to an electric vehicle backrest. Background Technology

[0002] Electric bicycles, also known as "electric vehicles," are purely electric vehicles powered by batteries and driven by electric motors. In recent years, they have become very popular in my country. The backrest of an electric bicycle is a support structure installed at the rear of the seat, primarily used to provide back support for rear passengers, improving riding comfort and enhancing safety.

[0003] Currently, electric vehicle backrests are generally composed of a frame made of steel or aluminum alloy die casting and a soft pad. The soft pad is usually a thin film filled with sponge. Because the film is thin, it is easy for the film to break under long-term friction from the human body, which will damage the backrest and affect its service life.

[0004] Therefore, it is necessary to provide an electric vehicle backrest to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that existing electric vehicle backrests are prone to damage due to the thin film on the cushion caused by prolonged friction from the human body, this utility model provides an electric vehicle backrest.

[0006] The electric vehicle backrest provided by this utility model includes: a backrest mechanism mounted on a second mounting plate, the backrest mechanism including: a backrest plate disposed on the second mounting plate, the backrest plate having two threaded holes, the two threaded holes being fixedly connected to two through holes on the second mounting plate by bolts; a decorative cover disposed on the backrest plate for covering the backrest plate, the decorative cover having multiple buckles, the multiple buckles being adapted to multiple slots on the backrest plate; and an elastic pad disposed on the backrest plate, the elastic pad being integrally formed with the backrest plate by injection molding.

[0007] Preferably, a U-shaped frame is fixedly installed on the second mounting plate. The U-shaped frame is integrally formed from a hollow steel pipe. Two first mounting plates are welded on the U-shaped frame. An elastic layer is provided on the outside of the U-shaped frame. The elastic layer is a foamed elastic layer.

[0008] Preferably, the two first mounting plates are located at both ends of the U-shaped frame, and both the back plate and the decorative cover are made of plastic.

[0009] Preferably, the elastic layer is U-shaped, and each end of the elastic layer is provided with a first protective sleeve, with the two first protective sleeves located outside the two first mounting plates respectively.

[0010] Preferably, a second protective sleeve is provided in the middle of the elastic layer, and the second protective sleeve is located outside the second mounting plate.

[0011] Preferably, each of the two first protective sleeves has a first through hole, and the two first through holes are respectively configured to correspond to the first mounting holes on the two first mounting plates.

[0012] Preferably, the second protective sleeve has a second through hole, which corresponds to the second mounting hole on the second mounting plate.

[0013] Compared with related technologies, the electric vehicle backrest provided by this utility model has the following beneficial effects:

[0014] This utility model provides an electric vehicle backrest. The U-shaped frame, integrally formed from hollow steel tubing, ensures the overall structural stability of the backrest while reducing material usage and achieving lightweight design. This makes carrying the backrest easier and less strenuous. The elastic layer on the outside of the U-shaped frame cushions the direct contact pressure between the user's hands and the frame when moving the vehicle or when the passenger grips it, preventing pain and improving the user experience. The elastic layer also protects the U-shaped frame from rain damage. The backrest mechanism meets the passenger's need for support, effectively cushioning the back and enhancing comfort. Furthermore, the elastic pad in the backrest is made from a single piece of elastic material, such as rubber or silicone, significantly reducing the risk of damage compared to backrests filled with a thin film. Its production and installation are also relatively simple. Attached Figure Description

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides an electric vehicle backrest, such as Figure 1-4 As shown, the electric vehicle backrest includes: a backrest mechanism mounted on a second mounting plate 3, the backrest mechanism including: a backrest plate 5 disposed on the second mounting plate 3, the backrest plate 5 having two threaded holes 6, the two threaded holes 6 being fixedly connected to two through holes 7 on the second mounting plate 3 by bolts; a decorative cover 8 disposed on the backrest plate 5 for covering the backrest plate 5, the decorative cover 8 having multiple buckles 9, the multiple buckles 9 being adapted to multiple slots 10 on the backrest plate 5; and an elastic pad 11 disposed on the backrest plate 5, the elastic pad 11 being integrally formed with the backrest plate 5 by injection molding.

[0023] In this embodiment, the U-shaped frame 1 adopts a hollow steel tube integral molding design, which can not only ensure the stability of the overall structure to support the armrest function and the weight of subsequent assembly components, but also reduce material usage and achieve lightweighting through the hollow structure. This makes it easier for people to carry the electric vehicle backrest. When assembling the backrest mechanism onto the second mounting plate 3, first align the two threaded holes 6 on the backrest plate 5 with the two through holes 7 on the second mounting plate 3. After alignment, bolts can be used to connect the two threaded holes 6 and the two through holes 7 together, thereby stably fixing the backrest plate 5 onto the second mounting plate 3. Then, the decorative cover 8, which is used to cover the backrest plate 5 to improve the appearance of the backrest, is fitted with multiple buckles 9 and correspondingly matched with multiple slots 10 on the backrest plate 5, realizing the convenient assembly and fixation of the decorative cover 8 on the backrest plate 5, thus completing the backrest mechanism. During assembly, since the elastic pad 11 is fixedly installed on the backrest 5, when a passenger sits on the electric vehicle and leans against the backrest mechanism, the elastic pad 11 can buffer the direct contact pressure between the passenger's back and the backrest 5, improving the comfort of leaning. Moreover, the elastic pad 11 is made of a single piece of elastic material, such as rubber or silicone, which greatly reduces the chance of damage compared to a backrest filled with a thin film of sponge. Its production and installation are also relatively simple. It should be noted that the top of the second mounting plate 3 has a backrest mounting part integrally formed with it, which can effectively ensure the strength of the backrest mechanism in use. The backrest mechanism can meet the passenger's leaning needs when sitting. Finally, through the synergistic effect of the U-shaped frame 1, the first mounting plate 2, the second mounting plate 3, the elastic layer 4 and the backrest mechanism, the electric vehicle backrest achieves the functions of a handrail, a backrest, and lightweight and comfortable use.

[0024] In a further preferred embodiment of the present invention, a U-shaped frame 1 is fixedly installed on the second mounting plate 3. The U-shaped frame 1 is integrally formed from a hollow steel pipe. Two first mounting plates 2 are welded on the U-shaped frame 1. An elastic layer 4 is provided on the outside of the U-shaped frame 1. The elastic layer is a foamed elastic layer.

[0025] In this embodiment, the elastic layer 4 provided on the outside of the U-shaped frame 1 can buffer the direct contact pressure between the hand and the U-shaped frame 1 when the user moves the electric vehicle or when the passenger holds it, so as to avoid pain and effectively improve the user experience.

[0026] In a further preferred embodiment of this utility model, the two first mounting plates 2 are respectively located at both ends of the U-shaped frame 1, and the backing plate 5 and the decorative cover 8 are both made of plastic.

[0027] In this embodiment, the plastic backrest 5 and decorative cover 8 have the advantages of being lightweight and low-cost, which can reduce the overall weight of the electric vehicle backrest and also reduce production costs.

[0028] In a further preferred embodiment of the present invention, the elastic layer 4 is configured as a U-shape, and a first protective sleeve 12 is provided at both ends of the elastic layer 4. The two first protective sleeves 12 are respectively located outside the two first mounting plates 2.

[0029] In this embodiment, the first protective sleeve 12 can shield and protect the first mounting plate 2, effectively preventing the first mounting plate 2 from rusting due to contact with rainwater.

[0030] In a further preferred embodiment of the present invention, a second protective sleeve 13 is provided in the middle of the elastic layer 4, and the second protective sleeve 13 is located outside the second mounting plate 3.

[0031] In this embodiment, the second protective sleeve 13 can shield and protect the second mounting plate 3, effectively preventing the second mounting plate 3 from rusting due to contact with rainwater.

[0032] In a further preferred embodiment of the present invention, each of the two first protective sleeves 12 is provided with a first through hole, and the two first through holes are respectively provided to correspond to the first mounting holes on the two first mounting plates 2.

[0033] In this embodiment, the use of the first through hole and the first mounting hole together allows people to easily install the electric vehicle backrest onto the electric vehicle they need to use using screws.

[0034] In a further preferred embodiment of the present invention, a second through hole is provided on the second protective sleeve 13, and the second through hole is correspondingly provided with a second mounting hole on the second mounting plate 3.

[0035] In this embodiment, the use of the second through hole and the second mounting hole makes it easy for people to further install the electric vehicle backrest onto the electric vehicle to be used with screws, thereby improving the stability of the electric vehicle backrest after installation.

[0036] In summary, compared with related technologies, this solution, through the U-shaped frame 1 integrally formed from hollow steel tubes, can ensure the overall stability of the electric vehicle backrest structure and reduce material usage to achieve lightweighting. This saves people physical effort when carrying the electric vehicle backrest. At the same time, the elastic layer 4 on the outside of the U-shaped frame 1 can buffer the direct contact pressure between the user's hand and the U-shaped frame 1 when the user moves the electric vehicle or when the passenger holds it, thus avoiding pain and effectively improving the user experience. Moreover, the elastic layer 4 can also protect the U-shaped frame 1 from rain and prevent it from being corroded by rainwater. Through the use of the backrest mechanism, the passenger's need for leaning can be met, effectively buffering the contact pressure on the passenger's back and improving leaning comfort. Furthermore, the elastic pad 11 in the backrest mechanism is made of a single piece of elastic material, such as rubber or silicone, which greatly reduces the probability of damage compared to backrests filled with a thin film of sponge. In addition, its production and installation are also relatively simple.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
