[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0024] The terms "top surface," "bottom surface," and "flush surface" refer to the normal operating state of the bumper and are used only for the purpose of describing this utility model and simplifying the description. They do not indicate or imply that the device or component 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 on this utility model.
[0025] like Figure 1-4 As shown, a bumper with an insert includes a main body 1 of the bumper, a concave foot pedal 2 on the main body 1, and an SMC insert 3 between the foot pedal 2 and the main body 1; the SMC insert 3 has an L-shaped structure, with its two outer sides respectively fitting the bottom surface of the foot pedal 2 and the inner wall of the main body 1, and a plurality of second reinforcing ribs 301 between its two inner sides.
[0026] The aforementioned bumper is compatible with heavy trucks, and the footrest 2 on it can be used by drivers, passengers, or maintenance personnel when inspecting the vehicle. When setting the SMC insert 3, the molded SMC insert is placed inside the injection molding machine, and then the main body 1 of the bumper is injection molded inside the injection molding machine. This allows the SMC insert 3 to be tightly connected to the main body 1, improving the strength of the connection between the two. The SMC insert provides support for the footrest 3, distributing the force on the footrest 2 when stepped on, thereby improving the stability of the footrest 2 and enhancing the safety of drivers and passengers when stepping on it.
[0027] Compared with the supporting iron parts in the prior art, the SMC insert 3 can reduce the product weight, meet the requirements of lightweight bumpers, and improve the vehicle's fuel economy and environmental performance. In addition, the SMC insert 3 has the advantage of corrosion resistance compared with the supporting iron parts, and can continuously provide reliable support for the foot pedal 2. The L-shaped SMC insert 3 forms a rigid node at its corner, and the two planes support each other, which can distribute the bending force to two directions and reduce stress concentration in one direction. Combined with the second reinforcing rib 301 between the two planes of the L-shaped structure, the SMC insert has excellent bending resistance and overall structural strength. Supporting it under the foot pedal 2 can effectively distribute the force on the foot pedal 2 and ensure the long-term stable and reliable use of the foot pedal 2.
[0028] Further improvements include, for example Figure 4As shown, the SMC insert 3 is provided with a pre-embedded nut 302. The pre-embedded nut 302 provides a reliable mounting point for the connection between the bumper and the vehicle body; and a protruding structure is formed at the pre-embedded nut 302. When the SMC insert 3 is placed into the injection mold, the protruding structure of the pre-embedded nut 302 can be used for positioning, so that the SMC insert 3 is stable in the injection mold and the injection molding effect is improved.
[0029] Further improvements include, for example Figure 4 As shown, the SMC insert 3 has a U-shaped groove-shaped second bend 303, which is distributed along the extension direction of the corner edge of the SMC insert 3. The second bend 303 and the SMC insert 3 are integrally die-cast, and the U-shaped groove-shaped second bend 303 can effectively disperse stress concentration, further enhancing the load-bearing and bending resistance of the SMC insert. By supporting the foot pedal 2 through the SMC insert 3, the foot pedal 2's resistance to trampling can be effectively improved.
[0030] Further improvements include, for example Figure 1 As shown, the foot pedal 2 is a rectangular cylindrical structure with openings at both ends, and is integrally formed with the main body 1. The cylindrical structure allows the foot pedal 2 to extend through the vehicle along the forward direction, forming a ventilation channel, thereby guiding airflow to the vehicle engine. This reduces air resistance while improving the engine's cooling effect.
[0031] Further improvements include, for example Figure 3 As shown, the main body 1 is provided with a U-shaped groove-shaped first bending portion 101, which is distributed circumferentially around the foot pedal portion 2. Like the second bending portion 303, the first bending portion 101 can effectively disperse stress concentration, thereby improving the load-bearing and bending resistance of the foot pedal portion 2 and enhancing the safety of the rider when stepping on it.
[0032] Further improvements include, for example Figure 3 As shown, a connecting part 103 is provided on the inner wall of the main body 1, adjacent to the foot pedal 2. The connecting part 103 is a threaded mounting hole reserved on the main body 1, used to connect the bumper 1 to the vehicle body. After the connecting part 103 adjacent to the foot pedal 2 is connected to the vehicle body, the vehicle body can provide a certain support for the foot pedal 2, thereby further improving the stability of the foot pedal 2.
[0033] Further improvements include, for example Figure 2As shown, a vertically distributed support rib 201 is provided between the inner top wall and inner bottom wall of the foot pedal part 2. The plane of the support rib 201 is set at an angle to the thickness direction of the main body 1. The support rib 201 and the foot pedal part 2 are integrally formed. The support rib 201 is set on the inner side of the foot pedal part 2, which can improve the strength of the foot pedal part 2 itself. Furthermore, when the support rib 201 is inclined, it can be used to resist the bending of the top and bottom walls of the foot pedal part 2, further improving the strength of the foot pedal part 2 itself.
[0034] Further improvements include, for example Figure 1 As shown, the horizontal height of the inner bottom wall of the foot pedal 2 gradually decreases outward along the thickness direction of the main body 1, and an anti-slip layer is provided on the inner bottom wall of the foot pedal 2. The anti-slip layer is a rubber pad, which increases the friction of the foot pedal 2 and prevents the driver and passengers from slipping when stepping on it, thereby improving the safety of the driver and passengers when inspecting the vehicle; its sloping bottom wall facilitates the drainage of water that enters the foot pedal 2, thereby reducing water accumulation and making it easier for the driver and passengers to step on and climb.
[0035] Further improvements include, for example Figure 2 As shown, the inner side of the SMC insert 3 is also provided with multiple first reinforcing ribs 102. The first reinforcing ribs 102 and second reinforcing ribs 301 are arranged alternately, and the two ends of the first reinforcing ribs 102 are respectively connected to the inner wall of the foot pedal part 2 and the main body 1. The first reinforcing ribs 102 and the main body 1 are injection molded at the same time to form an integral connection structure. The arrangement of the first reinforcing ribs 102 can provide support between the bottom of the foot pedal part 2 and the main body 1 to further improve the stability of the foot pedal part 2; at the same time, the first reinforcing ribs 102 can also limit the SMC insert 3 to improve the firmness of the connection between the SMC insert 3 and the main body 1, so as to prevent it from falling off and ensure the support effect of the SMC insert 3 on the foot pedal part 2.
[0036] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
