Description

Technical Field

[0001] This utility model relates to the field of automotive mudguard technology, specifically to a mudguard. Background Technology

[0002] In the logistics and heavy-duty operations sectors, electric heavy-duty trucks are widely used due to their environmental and energy-saving advantages. Mudguards, as a key component of electric heavy-duty trucks, primarily function to block mud, rainwater, and other debris splashed during vehicle operation, preventing damage to the truck body, road infrastructure, and the surrounding environment, and extending tire lifespan.

[0003] Reference Figure 1 Currently, the mudguard design of electric heavy-duty trucks generally adopts a multi-piece splicing structure. This means that for the protection needs of a single tire, three or more independent mudguards are configured. Each mudguard is arranged in segments along the tire's circumference, and adjacent mudguards are fixed together by a single bolt, forming a segmented protective structure. Furthermore, the mudguards located directly above the front and rear tires on one side of the vehicle need to be connected and fixed to a mudguard bracket welded to a pre-set position on the electric heavy-duty truck frame using a set of bolts. In mainstream industry designs, only one mudguard bracket is installed on each side of the vehicle, bearing the installation and fixing load of all the spliced ​​mudguards on that side. Taking a certain electric heavy-duty truck model with a high market share as an example, its four front tires require a total of 12 of these mudguards. The purchase price of each mudguard is approximately 300 yuan, resulting in an initial configuration cost of 3600 yuan for the mudguards alone, significantly increasing vehicle manufacturing costs and the procurement costs for end users.

[0004] The prominent problem lies in the unreasonable design of the fixed structure, which leads to multiple hidden dangers during use: on the one hand, adjacent mudguards on a single tire are spliced ​​and fixed by only a single bolt, resulting in concentrated stress at the connection point and a lack of redundant fixing protection, making the splice gaps prone to displacement due to vibration; on the other hand, only one mudguard bracket is set on each side of the vehicle body, which needs to bear the weight of multiple mudguards above the front and rear tires at the same time as the impact load during driving, resulting in excessive stress on the fixing support point, and the connection between the bracket and the mudguard and the frame is prone to loosening.

[0005] The combination of these two factors makes mudguards prone to overall wobbling and localized displacement when vehicles are traveling at high speeds, on bumpy roads, or under heavy loads. This results in continuous friction between the mudguards and the rapidly rotating tires. This friction not only accelerates wear and cracking of the mudguard edges, leading to frequent mudguard replacements, but also causes abnormal wear on the tire sidewalls, shortening tire lifespan and significantly increasing maintenance and replacement costs for users. Furthermore, frequent maintenance work consumes valuable vehicle operating time, reducing logistics efficiency. In addition, the continuous friction between the mudguards and tires can generate abnormal noises and vibrations, affecting vehicle stability, and in extreme cases, even causing road safety accidents due to mudguard detachment. Utility Model Content

[0006] The present invention aims to provide a mudguard to solve the problem of poor fixing effect of mudguards in the prior art.

[0007] To address the above problems, this application provides the following technical solution: A mudguard includes a mudguard assembly adapted to an electric heavy-duty truck tire and a mudguard bracket assembly fixed to the vehicle frame. The mudguard assembly includes two mudguards corresponding to each tire, symmetrically distributed along the tire axis. The mudguard bracket assembly includes three brackets welded to one side of the vehicle frame, one of which is a middle bracket located at the centerline of the front and rear tires on one side, and the other two are side brackets located near the outer edges of the front and rear tires, respectively. The mudguard directly above adjacent tires is fixed to the middle bracket by bolts, and the mudguard on the other side of each tire is fixed to the corresponding side bracket by bolts.

[0008] The working principle and beneficial effects of this utility model: To address the protection requirements of a single tire on an electric heavy-duty truck, the number of mudguards has been optimized to two, symmetrically distributed along the tire axis on both sides of the tire to form a semi-enclosed protective structure. The edges of the two mudguards maintain a certain safe distance from the outer surface of the tire, ensuring effective blocking of splashed debris while preventing frictional contact with the tire during driving.

[0009] Three mudguard brackets are welded to one side of the electric heavy-duty truck frame. One is a central bracket, positioned at the centerline of the front and rear tires on one side. The other two are side brackets, located near the outer edges of the front and rear tires, respectively. The central bracket is bolted to the mudguard joint directly above the front and rear tires, bearing the central load of the four mudguards (two tires in total). The side brackets are connected to the ends of the mudguards on the opposite side of the corresponding tires, evenly distributing the force on the mudguards across the three mudguard brackets. This fixing method increases the connection strength, and combined with the distributed layout of the mudguard brackets, it effectively absorbs vibrations and impacts during vehicle operation, preventing loosening or displacement caused by excessive stress at a single point.

[0010] As a preferred embodiment, the intermediate support is symmetrically fixed with support plates, and one side of the mudguard directly above the tire is fixed to the support plates with bolts. The symmetrically distributed support plates can evenly distribute the load transmitted by the mudguard along the central axis of the intermediate support, avoiding deformation of the intermediate support due to unilateral force.

[0011] As a preferred embodiment, the side bracket has multiple support wings fixed along its axis, and the other side of the mudguard directly above each tire, as well as another mudguard and support wing, are fixed together by bolts. The force on the two mudguards is transmitted to the side bracket through their respective support wing, thus achieving load distribution.

[0012] As a preferred option, the two mudguards configured for a single tire overlap partially at the corresponding side bracket.

[0013] As a preferred embodiment, the connection between the mudguard and the side bracket is provided with at least two bolts for connection.

[0014] As a preferred embodiment, the mudguard and support plate directly above the tire are connected by at least two bolts. Attached Figure Description

[0016] The reference numerals in the figure include: support wing 1, side bracket 2, mudguard 3, support plate 4, intermediate bracket 5, and frame 6. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method: Example: Refer to Figure 2 A mudguard 3 includes a mudguard assembly adapted to an electric heavy-duty truck tire and a mudguard bracket assembly fixed to a vehicle frame 6. The mudguard assembly includes two mudguards 3 configured for each tire and symmetrically distributed along the tire axis. The mudguard bracket assembly includes three mudguard brackets welded to one side of the vehicle frame 6, one of which is a middle bracket 5, located at the center axis of the front and rear tires on one side, and the other two are side brackets 2, respectively close to the outer edges of the front and rear tires. The opposite side of the mudguards 3 directly above adjacent tires is fixed to a support plate 4 welded to the middle bracket 5 by bolts. The other side of the mudguards 3 directly above the tires and the other side of the mudguards 3 of each tire are fixed to a support wing 1 welded to the side bracket 2 by bolts.

[0018] This application addresses the protection requirements of a single tire on an electric heavy-duty truck by optimizing the number of mudguards 3 to two, which are symmetrically distributed on both sides of the tire along the tire axis to form a semi-enclosed protective structure. The edge contours of the two mudguards 3 maintain a certain safe distance from the outer surface of the tire, ensuring effective blocking of splashed debris while avoiding frictional contact with the tire during driving.

[0019] Three mudguard brackets are welded to one side of the electric heavy-duty truck frame 6. One of them is a central bracket 5, located at the centerline of the front and rear tires on one side. The other two are side brackets 2, located near the outer edges of the front and rear tires respectively. The central bracket 5 is connected to the mudguard 3 splicing part directly above the front and rear tires by bolts. The side brackets 2 are fixed to the other side of the mudguard 3 directly above the tires and to the mudguard 3 on the side of each tire by bolts. This makes the force on the mudguard 3 evenly distributed on the three mudguard brackets. This fixing method increases the connection strength. Combined with the distributed layout of the mudguard brackets, it can effectively absorb the vibration and impact during vehicle operation and avoid excessive force at a single point, which could cause the mudguard 3 to loosen or shift.

These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
