Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of electric vehicle accessories, and in particular to a longitudinal folding support frame, a support mechanism and a shielding device of an electric vehicle. Background Art

[0002] This section introduces the background technology that may be relevant to various aspects of the embodiments of the present invention. It is believed that this section can provide readers with useful background information to help readers better understand the various aspects of the embodiments of the present invention. Therefore, it should be understood that the description in this section is for the above purpose and does not constitute an admission of prior art.

[0003] Electric vehicles are one of the most widely used modes of transportation, beloved by the public for their compact size, flexibility, and environmental friendliness. However, as living standards improve, the comfort of conventional electric vehicles is failing to meet people's growing demands. Electric vehicles generate wind while driving, but lack the protective outer shell of a car, providing no wind or sun protection. In cold winters, the wind is extremely cold, making it easy to catch a cold. In hot summers, direct sunlight can be extremely hot, and the hot air can easily cause discomfort. On days of persistent rain or inclement weather with flying dust and sand, riding an electric vehicle is extremely inconvenient.

[0004] Currently, in summer or rainy weather, most people ride with an umbrella in one hand or wear a raincoat. A few users also install an umbrella holder on the handlebars and then secure the umbrella to the holder. Second, this structure has only one fixed point, which significantly affects stability. Third, this structure is weak, making it difficult to control in rainy and windy weather, resulting in poor riding stability and a high risk of traffic accidents. Fourth, this structure only provides protection above the shoulders, so the rider's lower body will still get wet when riding in wind and rain.

[0005] Electric vehicle awnings effectively solve the above problems. There are a variety of electric vehicle awnings on the market, which either cannot be completely folded, or are too large to block the view after folding or do not comply with current regulations. They are difficult to disassemble and store when not needed, which is very inconvenient. Utility Model Content

[0072] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0073] like Figures 1 to 11As shown, an embodiment of the present invention provides a longitudinal folding support frame for an electric vehicle shielding device, comprising: at least two longitudinal support frames 1 connected end to end; the longitudinal support frames 1 extend and support in the longitudinal direction of an electric vehicle 2; the longitudinal support frame 1 comprises a first support rod group 11 and a second support rod group 12 symmetrically arranged; the first support rod group 11 and the second support rod group 12 extend or fold in the longitudinal direction; the first support rod group 11 comprises: a first folding rod 111 and a second folding rod 112, the first folding rod 111 and the second folding rod 112 being connected end to end, and the first folding rod 111 and the second folding rod 112 being movably connected; the second support rod group 12 comprises: a third folding rod 113 and a fourth folding rod 114, the third folding rod 113 and the fourth folding rod 114 being connected end to end, and the third folding rod 113 and the fourth folding rod 114 being movably connected. The following is a detailed description of the longitudinal folding support frame for an electric vehicle shielding device provided by an embodiment of the present invention.

[0074] like Figures 1 to 6 As shown, in the embodiment of the present invention, a support beam 3 is provided at the end of the longitudinal support frame; the support beam 3 includes a first support beam 31 provided at the front of the longitudinal support frame 1 and a second support beam 32 provided at the rear of the longitudinal support frame 1; the first end of the first folding rod 111 is movably connected to the first support beam 31; the second end of the second folding rod 112 is movably connected to the second support beam 32; the first end of the third folding rod 113 is movably connected to the first support beam 31; the second end of the fourth folding rod 114 is movably connected to the second support beam 32; the second end of the first folding rod 111 is movably connected to the first end of the second folding rod 112; the second end of the third folding rod 113 is movably connected to the first end of the fourth folding rod 114. Two longitudinal support frames 1 adjacent to each other can share one support beam 3.

[0075] like Figures 2 to 6As shown, in the embodiment of the present invention, the first end of the first support beam 31 is provided with a first connecting member 311, the second end of the first support beam 31 is provided with a second connecting member 312, the first end of the second support beam 32 is provided with a third connecting member 313, and the second end of the second support beam 32 is provided with a fourth connecting member 314; the first end of the first folding rod 111 is hinged to the first end of the first support beam 31 through the first connecting member 311; the second end of the second folding rod 112 is hinged to the first end of the second support beam 32 through the third connecting member 313; the first end of the third folding rod 113 is hinged to the second end of the first support beam 31 through the second connecting member 312; and the second end of the fourth folding rod 114 is hinged to the second end of the second support beam 32 through the fourth connecting member 314. In the embodiment of the present invention, the first connecting member 311 and the second connecting member 312 are respectively sleeved on the two ends of the first support beam 31; the third connecting member 313 and the fourth connecting member 314 are respectively sleeved on the two ends of the second support beam 32. like Figures 7 to 11 When the device is in the unfolded state, the first connecting member 311, the second connecting member 312, the third connecting member 313, and the fourth connecting member 314 restrict the first folding rod 111 and the second folding rod 112 from further unfolding outward, ensuring that the first folding rod 111 and the second folding rod 112 can smoothly cooperate with the first connecting member 311, the second connecting member 312, the third connecting member 313, and the fourth connecting member 314. After unfolding, the angle at which the first support rod group 11 and the second support rod group 12 are connected is an obtuse angle when in use. That is, when the first support rod group 11 and the second support rod group 12 are unfolded, the angle at which the first folding rod 111 and the second folding rod 112 are connected is greater than 90°, restricting the first folding rod 111 and the second folding rod 112 from rotating inward relative to each other. This prevents the longitudinal support frame 1 from automatically folding back.

[0076] like Figures 8 to 11 As shown, in another embodiment of the present invention, in order to save costs as much as possible and simplify the product structure, the first end of the first folding rod 111 is hinged to the first end of the first support beam 31 through a rotating shaft; the second end of the second folding rod 112 is hinged to the first end of the second support beam 32 through a rotating shaft; the first end of the third folding rod 113 is hinged to the second end of the first support beam 31 through a rotating shaft; the second end of the fourth folding rod 114 is hinged to the second end of the second support beam 32 through a rotating shaft.

[0077] like Figure 12As shown, in the embodiment of the present invention, a transverse support rod 4 is provided on the support beam 3; the transverse support rod 4 is connected to the support beam 3 via a transverse connecting member 43. The transverse support rod 4 is used to support the canopy 6 provided on the longitudinal folding support frame 1.

[0078] like Figures 1 to 12 As shown, in the embodiment of the present invention, in order to further save costs and simplify the product structure, the second end of the first folding rod 111 and the first end of the second folding rod 112 are hinged through a rotating shaft; the second end of the third folding rod 113 and the first end of the fourth folding rod 114 are hinged through a rotating shaft.

[0079] In order to further reflect the advanced nature of the longitudinal folding support frame of the electric vehicle shielding device provided by the present invention, the embodiment of the present invention also provides a support mechanism of the electric vehicle shielding device, such as Figures 13-18 As shown, the support mechanism includes: a vertical support bracket 7 and a longitudinal folding support bracket 1. The longitudinal folding support bracket 1 is arranged above the electric vehicle; the bottom 77 of the vertical support bracket 7 is fixedly connected to the electric vehicle 2, and the front end of the longitudinal folding support bracket 1 is movably connected to the top of the vertical support bracket 7; the vertical support bracket 7 is used to support the front of the longitudinal folding support bracket 1 to a predetermined height; the longitudinal folding support bracket 1 is the longitudinal folding support bracket described above. The following is a detailed description of the support mechanism of the electric vehicle shielding device provided by the embodiment of the utility model.

[0080] like Figures 13 to 16As shown, in the embodiment of the present invention, the vertical support bracket 7 includes: a pair of symmetrically arranged vertical support rods 71, the vertical support rods including a first vertical folding rod 711 and a second vertical folding rod 712, the first vertical folding rod 711 and the second vertical folding rod 712 are connected end to end, and the first vertical folding rod 711 and the second vertical folding rod 712 are hinged by a rotating shaft; a telescopic locking device 70 is provided on the vertical support rod, and the telescopic locking device 70 is used to maintain the extended state of the vertical support rod 71 and lock it. After the vertical support rod 71 is unfolded, the telescopic locking device 70 will maintain the extended state of the vertical support rod 71 and lock it to prevent it from moving outward. A support beam 3 is provided at the front end of the longitudinal folding support frame; the top of the vertical support bracket 7 is movably connected to the support beam 3. In the embodiment of the present invention, when folding, the locking state of the telescopic locking device 70 is released, and the rotation axis of the vertical support rod 71 is pushed inward. The first vertical folding rod 711 and the second vertical folding rod 712 rotate and fold inward along the rotation axis 10, and the vertical support bracket 1 is folded and stored in the longitudinal direction. The entire vertical support bracket 7 is folded downward so that it is attached to the front of the electric vehicle. During the folding process, the entire front windshield bracket is folded toward the lower beam.

[0081] In order to further reflect the advanced nature of the folding support mechanism of the electric vehicle shielding device provided by the present invention, the embodiment of the present invention also provides an electric vehicle shielding device, such as Figure 19 As shown, the electric vehicle shielding device includes a support mechanism and a protective canopy 8 arranged on the support mechanism. The folding support mechanism is also fixedly connected to a windshield 5, and the windshield is vertically arranged above the front of the electric vehicle. The folding support mechanism is the above-mentioned folding support mechanism.

[0082] In summary, the longitudinal folding support frame, support mechanism and shielding device of the electric vehicle shielding device provided by the embodiment of the present invention, through at least two longitudinal support frames connected end to end, the two longitudinal support frames are extended or folded in the longitudinal direction, so as to realize the longitudinal folding and storage of the electric vehicle canopy. After the transverse support rod is unfolded, the longitudinal folding support frame will be kept in the extended state and locked to prevent the longitudinal support frame from rotating relatively inward. In this way, the longitudinal support frame can be prevented from automatically recovering and folding, and the vertical support rod can only move in the direction of a predetermined inward angle when it moves, so as to realize transverse folding and storage. The folding support mechanism of the electric vehicle shielding device provided by the embodiment of the present invention can be stored and folded longitudinally and further stored and folded vertically, and it is convenient to disassemble and store at any time when not needed.
