Description

Technical Field

[0001] This utility model belongs to the field of mudguards, specifically a detachable reinforced mudguard for automobiles. Background Technology

[0002] Mudguards, as an important component for vehicle underbody protection, primarily function to block mud, sand, stones, and other debris kicked up by the wheels during driving, protecting the vehicle body and chassis from damage and thus improving driving safety.

[0003] Currently, most car mudguards on the market are made of materials such as plastic, rubber, or metal. Their structure usually includes an arc-shaped plate that matches the wheel profile. The mudguard is bolted to a specific location on the vehicle chassis, such as the wheel, to form an effective protective barrier. During use, the mudguard can withstand the impact of mud and sand kicked up by the wheel, effectively preventing mud and sand from splashing. However, in actual use, due to the generally low strength and rigidity of the mudguard, it is prone to deformation or even damage when faced with prolonged or high-intensity mud and sand impacts, thus affecting its protective effect. Furthermore, since mudguards are mostly designed as a single piece, if one side of the plate is damaged by mud and sand impacts, the entire plate needs to be replaced, which not only increases the cost of use but also wastes resources.

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, this is the first embodiment of the present invention, which provides a detachable reinforced mudguard for automobiles, including...

[0024] The mudguard unit 100 includes a first baffle 110, a second baffle 120 disposed on one side of the first baffle 110, a groove 130 formed on the top of the first baffle 110 and the second baffle 120, a connecting assembly 140 disposed in the inner cavity of the groove 130 and used to connect the first baffle 110 and the second baffle 120, a reinforcing rib 150 fixedly connected to the inner cavity of the second baffle 120, a connecting groove 160 formed on one side of the first baffle 110, and a reinforcing plate 170 fixedly connected to the bottom of the first baffle 110 and the second baffle 120.

[0025] The connecting assembly 140 includes a threaded cylinder 141 fixedly connected to the inner cavity of the groove 130, and a threaded rod 142 threadedly connected to the inner cavity of the threaded cylinder 141.

[0026] like Figure 1-5 As shown, when it is necessary to install or remove the mudguard, the threaded rod 142 is rotated to connect or separate it from the threaded cylinder 141, thereby achieving a tight connection or easy separation of the first baffle 110 and the second baffle 120. The two ends of the reinforcing rib 150 are respectively located in the inner cavity of the second baffle 120 and the inner cavity of the connecting groove 160 on one side of the first baffle 110, which can increase the structural strength of both and provide additional support. At the same time, the reinforcing plate 170 is set at its bottom and can directly contact the mud and sand, thereby resisting the impact of mud and sand, which greatly improves the rigidity of the first baffle 110 and the second baffle 120, thereby extending their service life.

[0027] Example 2

[0028] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] In this embodiment, a sealing strip 121 is fixedly connected to one side of the second baffle 120, and the side of the sealing strip 121 away from the second baffle 120 is in contact with the first baffle 110.

[0030] One end of the reinforcing rib 150 is located in the inner cavity of the second baffle 120, and the other end extends into the inner cavity of the connecting groove 160 and is movably connected to the inner cavity of the connecting groove 160. The reinforcing rib 150 and the connecting groove 160 are adapted to each other. Both the reinforcing rib 150 and the reinforcing plate 170 are made of stainless steel.

[0031] like Figure 1-4 As shown, the presence of the sealing strip 121 effectively fills the tiny gap between the second baffle 120 and the first baffle 110, thereby significantly improving the sealing performance between the second baffle 120 and the first baffle 110, preventing mud and sand from seeping out through the gap, and improving the mud-blocking quality. The reinforcing rib 150 and the reinforcing plate 170 are both made of high-quality stainless steel. The high strength and rigidity of stainless steel enable the reinforcing rib 150 and the reinforcing plate 170 to better withstand the impact and vibration of mud and sand, maintaining the stability and integrity of the first baffle 110 and the second baffle 120.

[0032] Example 3

[0033] Reference Figure 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] In this embodiment, the surface of the threaded rod 142 is movably connected to the limiting sleeve 143 through the bearing. The front and back sides of the inner cavity of the groove 130 are provided with limiting grooves 144. Both ends of the limiting sleeve 143 extend into the inner cavity of the limiting groove 144 and are slidably connected to the inner cavity of the limiting groove 144.

[0035] like Figure 3-5 As shown, the sliding connection between the limiting sleeve 143 and the limiting groove 144 provides a clear movement trajectory for the threaded rod 142. When the threaded rod 142 moves, it slides along the inner cavity of the limiting groove 144 with the limiting sleeve 143, thereby ensuring that it will not deviate from the predetermined path during rotation, thus ensuring the stability and reliability of the connection.

[0036] In use, when installing or removing the mudguard, first place the first baffle 110 in the predetermined position, and simultaneously align the second baffle 120 with the first baffle 110. At this time, the second baffle 120 will drive the reinforcing rib 150 into the inner cavity of the connecting groove 160, thereby achieving a preliminary connection between the first baffle 110 and the second baffle 120. The reinforcing rib 150 can increase the structural strength of both and provide additional support. Then, by rotating the threaded rod 142 in the forward direction, the threaded rod 142 will gradually approach the threaded cylinder 141 and screw into the threaded cylinder 141 until the two are tightly connected, thus completing the installation connection operation. Conversely, by rotating the threaded rod 142 in the reverse direction, the threaded rod 142 will gradually rotate inside the threaded cylinder 141 and move away until the two are separated. Then, pull the second baffle 120 or the first baffle 110 to separate the reinforcing rib 150 from the connecting groove 160, thereby achieving the disassembly operation and allowing it to be threadedly connected or separated from the threaded cylinder 141. This achieves a tight connection or easy disassembly of the first baffle 110 and the second baffle 120. The convenient disassembly and assembly of the first baffle 110 and the second baffle 120 facilitates maintenance and replacement, reducing usage costs. When the first baffle 110 and the second baffle 120 are in use, the reinforcing rib 150 increases their structural strength and provides support. At the same time, the reinforcing plate 170 is set at its bottom and can directly contact the mud and sand, thereby resisting the impact of the mud and sand, greatly improving the rigidity of the first baffle 110 and the second baffle 120, thus extending their service life.

[0037] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
