[0041] like Figures 1 to 5 As shown, the first embodiment of the utility model provides a side protection device, comprising:

[0042] The connecting bracket 100 includes a web 102. Along the width direction of the web 102, wing plates 104 perpendicular to the web 102 are arranged on both sides of the web 102. A bent plate 106 is arranged at one end of the wing plate 104 away from the web 102. The bent plate 106 is parallel to the web 102. A first connecting end 107 and a second connecting end 109 are formed on the connecting bracket 100. The first connecting end 107 is used to be connected to the bottom plate 116 of the vehicle.

[0043] The side protection plate 108 is connected to the second connection end 109 .

[0044] According to the side protection device provided by the embodiment of the first aspect of the utility model, by setting the connecting bracket 100 into a combination of a web 102 and a wing plate 104 perpendicular to the web 102, and setting a bent plate 106 at the end of the wing plate 104, the connecting bracket 100 is more stable in structure, and can effectively resist external impacts, such as side collisions or other unexpected situations during vehicle driving, thereby protecting the safety of vehicles and pedestrians. By providing a first connecting end 107 and a second connecting end 109 on the connecting bracket 100, the side protection device can be conveniently connected to the bottom plate 116 and the side protection plate 108 of the vehicle, simplifying the installation process, improving work efficiency, and also reducing installation costs. By connecting the side protection plate 108 to the second connecting end 109, the side of the vehicle can be effectively protected. When the vehicle is hit from the side, the side protection plate 108 can absorb and disperse the impact force, reducing direct damage to the vehicle structure. In addition, due to the reasonable structural design of the side protection device, it can be applied to different types of vehicles and has high versatility and adaptability.

[0045] Please continue to see Figures 1 to 5 In the side protection device provided by the embodiment of the first aspect of the utility model, the connecting bracket 100 is the main part of the side protection device, and the connecting bracket 100 is mainly composed of a web 102, a wing plate 104 and a bent plate 106. The web 102, as the main structure of the connecting bracket 100, is made of high-strength material to ensure that the structural integrity can be maintained when subjected to external impact.

[0046] The wing plates 104 are arranged perpendicular to the web 102, which enhances the overall stability of the connecting bracket 100 and also provides a stable connection foundation for the side guard plates 108. It should be noted that the wing plates 104 are formed on both sides of the web 102 in the width direction. The width direction of the web 102 mentioned here refers to the width direction of the web 102. Figure 5 The left and right sides of the web 102 are shown.

[0047] The design of the bent plate 106 not only increases the structural rigidity of the connecting bracket 100 and improves the structural rigidity of the web 102 and the wing plate 104, but also makes the structure of the entire connecting bracket 100 more compact and easy to install and use.

[0048] It can be understood that the web 102 , the wing plate 104 and the bent plate 106 generally form a C-shaped structure.

[0049] The first connection end 107 and the second connection end 109 are specially provided on the connection bracket 100. The first connection end 107 is used to connect with the bottom plate 116 of the vehicle, and various connection methods can be used, such as bolt connection, welding, etc., to ensure a firm and reliable connection. The second connection end 109 is used to connect with the side guard plate 108, and by cooperating with the corresponding structure on the side guard plate 108, the two are tightly connected.

[0050] In the embodiment of the utility model, the connecting bracket 100 is an aluminum alloy connecting bracket 100 or a steel connecting bracket 100. It is understandable that the connecting bracket 100 can be directly formed by rolling and bending an aluminum alloy plate, which has a simple structure, light weight, low cost, and is easy to ensure dimensional accuracy and product consistency. Alternatively, the connecting bracket 100 can be made of steel.

[0051] The side guard plate 108 is the protective part of the side guard device. Its main function is to directly bear and disperse the impact force from the side to protect the safety of the vehicle and pedestrians. The side guard plate 108 is made of materials with excellent impact resistance, such as high-strength steel plate or aluminum alloy plate, to ensure that it can effectively absorb and disperse the force when it is impacted. The shape and size of the side guard plate 108 are customized according to the specific model and protection requirements of the vehicle to ensure that it can fit closely to the side of the vehicle and provide all-round protection.

[0052] By adopting the side protection device provided by the utility model, the protection capability of the vehicle side can be effectively improved, the damage and accident risks caused by side impact can be reduced, and a strong guarantee can be provided for the safety of vehicles and pedestrians.

[0053] According to one embodiment of the utility model, the web 102 located on the first connecting end 107 is provided with at least two connecting holes 110. When the first connecting end 107 is connected to the floor 116 of the vehicle, the fastener 126 is suitable for passing through the connecting hole 110 to connect the first connecting end 107 to the floor 116 of the vehicle.

[0054] like Figure 4 As shown, the web 102 located on the first connection end 107 is provided with at least two connection holes 110 , and the connection holes 110 are provided to facilitate a stable connection with the bottom plate 116 of the vehicle.

[0055] In the actual installation process, when the first connection end 107 needs to be connected to the vehicle's floor 116, fasteners 126 (such as bolts, nuts, etc.) will be inserted into these connection holes 110. One end of the fastener 126 is in close contact with the web 102 of the connection bracket 100, and the other end is connected to the vehicle's floor 116. By properly tightening the fastener 126, it can be ensured that the connection between the first connection end 107 and the vehicle's floor 116 is firm and reliable and not easy to loosen.

[0056] This setting method not only simplifies the installation process and improves installation efficiency, but also ensures that the connection between the side guard and the vehicle is stable and reliable. During the driving process of the vehicle, even if it encounters bumps or vibrations, the side guard can maintain a close connection with the vehicle and will not fall off or shift.

[0057] In addition, the design of providing at least two connection holes 110 also enhances the stability of the connection. Multiple connection points disperse the impact force, so that the side protection device can better withstand and disperse the force when subjected to external impact, thereby protecting the safety of vehicles and pedestrians.

[0058] According to one embodiment of the utility model, the web 102 located on the second connection end 109 is provided with a mounting hole 112. When the side guard plate 108 is installed on the second connection end 109, the fastener 126 is suitable for passing through the mounting hole 112 to install the side guard plate 108 on the second connection end 109.

[0059] Please continue to see Figure 4 The web 102 located on the second connection end 109 is provided with a mounting hole 112 , and the mounting hole 112 is provided to facilitate installation and fixation with the side protection plate 108 .

[0060] In the actual installation process, when the side guard plate 108 needs to be installed on the second connection end 109, the fasteners 126 (such as bolts, rivets, etc.) will be inserted into these installation holes 112. One end of the fastener 126 is in close contact with the side guard plate 108, and the other end is connected to the web 102 of the connection bracket 100. By properly tightening or fixing the fastener 126, it can be ensured that the connection between the side guard plate 108 and the second connection end 109 is firm and reliable and not easy to fall off.

[0061] This arrangement not only simplifies the installation process of the side guard plate 108 and improves the installation efficiency, but also ensures a stable and reliable connection between the side guard plate 108 and the connecting bracket 100. During the driving of the vehicle, even if there are bumps or vibrations, the side guard plate 108 can maintain a tight connection with the connecting bracket 100 without loosening or displacement.

[0062] In addition, the design of providing the mounting holes 112 also provides flexible installation options. According to different vehicle models and protection requirements, suitable fasteners 126 and installation methods can be selected to meet specific installation requirements.

[0063] According to an embodiment of the present invention, an arc-shaped transition section 114 is further formed on the connecting bracket 100 , and the arc-shaped transition section 114 is connected between the first connecting end 107 and the second connecting end 109 .

[0064] Please continue to see Figure 4 By providing an arc-shaped transition section 114 between the first connection end 107 and the second connection end 109, not only the structural rigidity of the connection bracket 100 is enhanced, but also the overall stability of the side protection device is improved. The provision of the arc-shaped transition section 114 makes the transition between the first connection end 107 and the second connection end 109 of the connection bracket 100 smoother, reducing the stress concentration phenomenon that may be caused by right-angle or sharp-angle transition. This smooth transition design helps to disperse and absorb external impact forces and improve the impact resistance of the side protection device. The arc-shaped transition section 114 can also increase the flexibility of the connection bracket 100, so that it can better adapt to deformation when impacted and reduce the possibility of structural damage. This design helps to protect the overall structural integrity of the side protection device and extend its service life.

[0065] In addition, the arc-shaped transition section 114 also optimizes the appearance of the side protection device, making its lines smoother and more beautiful. This arrangement enables the side protection device to achieve a good balance between practicality and aesthetics.

[0066] According to an embodiment of the present invention, at least two groups of connecting brackets 100 are disposed on the side protection plate 108 at intervals along the length direction of the side protection plate 108 .

[0067] like Figure 3 As shown, by arranging at least two groups of connecting brackets 100 at intervals along the length direction of the side guard plate 108, the connection stability between the side guard plate 108 and the connecting bracket 100 and the strength of the overall structure can be significantly enhanced. By arranging multiple groups of connecting brackets 100, the side guard plate 108 can be fixed to the connecting bracket 100 at multiple points to form a stable structure supported by multiple points. This multi-point connection method can not only effectively disperse the impact force, but also prevent the side guard plate 108 from shaking or falling off when it is hit from the side.

[0068] Meanwhile, the spaced connection brackets 100 can also meet the requirements of different lengths of side protection plates 108. According to the specific model and protection requirements of the vehicle, the number and position of the connection brackets 100 can be flexibly adjusted to meet the installation requirements of side protection plates 108 of different lengths.

[0069] In addition, this arrangement also facilitates the installation and removal of the side guard plate 108. When the side guard plate 108 needs to be replaced or repaired, a group of connecting brackets 100 can be removed or installed separately without disassembling the entire side guard device, thereby improving the convenience of repair and replacement.

[0070] According to an embodiment of the present invention, the connecting bracket 100 further includes a reinforcing rib, and two ends of the reinforcing rib are respectively connected between the first connecting end 107 and the second connecting end 109 .

[0071] In the embodiment of the utility model, by adding reinforcing ribs, the overall strength and stability of the connecting bracket 100 can be significantly improved.

[0072] First, the reinforcing ribs can effectively disperse and resist the impact force from the side. During the vehicle driving process, especially when encountering a collision or side impact, the reinforcing ribs can bear and absorb part of the impact force, reducing the damage to the side guard plate 108 and the entire vehicle structure.

[0073] Secondly, the presence of the reinforcing ribs strengthens the overall structural rigidity of the connecting bracket 100, so that the connecting bracket 100 is not easily deformed or broken when subjected to external forces.

[0074] In addition, the design of the reinforcing ribs can also improve the durability of the connecting bracket 100. Since the reinforcing ribs can share part of the load, it helps to reduce the risk of stress concentration and fatigue fracture of the connecting bracket 100 during long-term use.

[0075] In practical applications, the shape, size and layout of the reinforcing ribs can be optimized according to specific needs. For example, straight, curved or other shaped reinforcing ribs can be used to adapt to different structures and installation spaces of the connecting bracket 100. At the same time, the material of the reinforcing ribs can also be flexibly selected according to actual needs, and examples are not given here one by one.

[0076] According to an embodiment of the present invention, a crash strip is provided on the side of the side protection plate 108 facing away from the second connection end 109 .

[0077] In the embodiment of the utility model, by arranging the anti-collision strip on the side protection plate 108, it is possible to provide the vehicle with additional side collision protection, and enhance the overall protection effect of the side protection device. The anti-collision strip is usually made of a material with excellent impact resistance, such as rubber, polyurethane or special synthetic materials. They fit tightly to the outside of the side protection plate 108, forming an additional buffer layer. When the side of the vehicle is hit or impacted, the anti-collision strip can first contact and absorb part of the impact force, reducing the impact force directly acting on the side protection plate 108 and the vehicle structure.

[0078] The setting of the anti-collision strip not only improves the impact resistance of the side protection device, but also helps to reduce noise and vibration during collision, and improves riding comfort. At the same time, the anti-collision strip also has a certain degree of wear resistance and weather resistance, and can maintain stable performance under different environmental conditions, thus extending the service life of the side protection device.

[0079] In addition, the anti-collision strip can be customized according to needs to adapt to different vehicle models and protection requirements. Its color, shape and size can be matched according to the overall design style of the vehicle to achieve a perfect combination of beauty and practicality.

[0080] The second aspect of the present utility model provides a vehicle, comprising a bottom plate 116 and the above-mentioned side protection device;

[0081] At least one set of side protection devices is disposed on both sides of the bottom plate 116 along the width direction of the bottom plate 116 .

[0082] According to the vehicle provided by the embodiment of the second aspect of the utility model, the side protection device is provided so that the side protection device is an outrigger beam structure. The side of the vehicle has sufficient structural rigidity, which can ensure that the side of the vehicle can withstand a large impact load, thereby effectively improving the safety performance of the vehicle.

[0083] See also Figure 1 The second embodiment of the utility model provides a vehicle, which includes a bottom plate 116 and the above-mentioned side protection device. This arrangement closely combines the side protection device with the vehicle, providing a more comprehensive and effective side protection for the vehicle.

[0084] Specifically, at least one set of side protection devices is disposed on both sides of the bottom plate 116 along the width direction of the bottom plate 116. Such a layout ensures that both sides of the vehicle can be fully protected, and no matter from which direction the vehicle is hit from the side, the side protection devices can effectively absorb and disperse the impact force, thereby protecting the safety of the vehicle and pedestrians.

[0085] The side protection device is firmly connected to the bottom plate 116 of the vehicle through the connecting bracket 100. The first connecting end 107 on the connecting bracket 100 is specially designed with a connecting hole 110, so that the connecting bracket 100 and the bottom plate 116 can be tightly fixed by fasteners 126 such as bolts. This connection method is simple and reliable, ensuring the stability and safety of the side protection device during the driving of the vehicle.

[0086] At the same time, the side protection plate 108 on the side protection device is directly connected to the second connection end 109 of the connection bracket 100. The side protection plate 108 is made of high-strength material and can effectively withstand and disperse the force of side impact. A collision strip is also provided on the side away from the second connection end 109, which further enhances the impact resistance of the side protection device.

[0087] According to one embodiment of the present invention, the bottom plate 116 includes:

[0088] Upper cover plate 118;

[0089] A lower cover plate 120 is disposed opposite to the upper cover plate 118;

[0090] Polyurethane foam 122, disposed between the upper cover plate 118 and the lower cover plate 120;

[0091] The embedded component 124 is disposed between the lower cover plate 120 and the polyurethane foam 122 . A fastener 126 is embedded in the embedded component 124 . The first connecting end 107 is detachably mounted on the fastener 126 .

[0092] See also Figure 2 In the embodiment of the utility model, the upper cover plate 118 is the external structure of the bottom plate 116, providing a flat surface for easy connection and installation with other components. The lower cover plate 120 is arranged opposite to the upper cover plate 118, and the space between the two is filled with polyurethane foam 122. As an excellent sound insulation and heat insulation material, the polyurethane foam 122 can effectively reduce the noise and heat generated by the vehicle during driving and improve the comfort of the vehicle interior environment.

[0093] In the internal structure of the bottom plate 116, the embedded part 124 is placed between the lower cover plate 120 and the polyurethane foam 122. This arrangement enables the first connection end 107 of the side guard to be detachably mounted on the fastener 126, thereby achieving a stable connection between the side guard and the bottom plate 116. At the same time, due to the presence of the embedded part 124, the position of the fastener 126 is fixed, ensuring the accuracy and reliability of the installation.

[0094] In the actual installation process, the position and tightness of the fastener 126 can be adjusted to achieve accurate alignment and a firm connection between the side guard and the bottom plate 116. This detachable installation method not only facilitates the removal and replacement of the side guard, but also improves the convenience of repair and maintenance.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
