Description

TECHNICAL FIELD

[0001] The utility model relates to the protection device technical field of straddle type vehicle, especially a protection structure, and simultaneously, the utility model relates to a vehicle applying the protection structure. BACKGROUND

[0002] In the related art, for straddle type vehicles, such as fuel type motorcycles or electric drive type motorcycles, the bumper and other protection structures are important safety components of the vehicle body, and in the event of a collision, impact or rollover, these protection structures protect the legs of the rider and the vehicle body from damage through their blocking or supporting effect.

[0003] The current protection structure, taking the bumper as an example, usually adopts an integral structure, is annular as a whole, and is symmetrically arranged about the center line of the vehicle width direction. When one side of the bumper is impacted by an external force, the other side of the bumper will be correspondingly offset, which not only causes a safety hazard to the driver's legs, but also easily causes damage to the vehicle, and is not conducive to improving the protection effect of the vehicle and the driver. SUMMARY

[0004] Therefore, the utility model aims to provide a protection structure to improve the protection effect of the vehicle and the driver.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A protection structure is applied to a straddle type vehicle with an exhaust pipe and comprises a mounting bracket connected to the frame of the vehicle and a rear bumper installed on the mounting bracket.

[0007] The connecting point between the mounting bracket and the frame is located on the inner side of the exhaust pipe protection cover in the vehicle, and the rear bumper is arranged through the exhaust pipe protection cover and has an exposed part exposed on the outer side of the exhaust pipe protection cover.

[0008] Further, the frame has a side box bracket, and the mounting bracket is detachably installed on the side box bracket.

[0009] Further, the mounting bracket comprises a sleeve for inserting the rear bumper and mounting plates arranged on both sides of the sleeve, and the mounting plates on both sides are detachably connected to the side box bracket, and each mounting plate is provided with the connecting point.

[0010] Further, the rear bumper comprises a rear bumper body and a connecting rod arranged at one end of the rear bumper body away from the exposed part; the cross-sectional area of the connecting rod is smaller than that of the rear bumper body, and the rear bumper is connected to the sleeve by screwing the connecting rod.

[0011] Further, at least one of the rear bumper body and the connecting rod is provided with a weight-reducing hole.

[0012] Further, the part of the exposed part away from the mounting bracket is provided with a bumper protection part, which is detachably mounted on the exposed part.

[0013] Further, the bumper protection part is mounted on the exposed part by a threaded connecting piece, and the axial direction of the threaded connecting piece is consistent with the extension direction of the rear bumper.

[0014] Further, the first end of the bumper protection part is provided with a first groove, and part of the exposed part is inserted into the first groove; and / or, the second end of the bumper protection part is provided with a second groove, and the head of the threaded connecting piece is embedded in the second groove.

[0015] Further, the rear bumper extends along the width direction of the vehicle and is located above the exhaust pipe, and the rear bumper is arranged close to the exhaust pipe; and / or, a sealing part is arranged between the exhaust pipe protection cover and the rear bumper to seal the gap therebetween.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The protective structure makes the connecting point of the mounting bracket and the vehicle frame located on the inner side of the exhaust pipe protection cover, and the rear bumper extends from the connecting point with the vehicle frame to the outer side of the exhaust pipe protection cover, which can reduce the risk of overall offset of the existing frame type protection device damaging the driver's legs, and through the arrangement of the exposed part, the exhaust pipe protection cover can be prevented from being damaged when the vehicle falls, and the exhaust pipe protection cover and the driver can be better protected, thereby helping to improve the protection effect on the vehicle and the driver.

[0018] By detachably mounting the mounting bracket on the side box bracket, the mounting bracket is directly fixed on the side box bracket, the structural strength of the side box bracket can be fully utilized, the impact resistance of the rear bumper in the collision can be improved, and the damage risk to the vehicle frame can be reduced.

[0019] The mounting bracket comprises a sleeve and mounting plates on both sides, which can form a stable triangular stress system and significantly enhance the torsional stiffness of the protective structure. This design can more evenly disperse the impact force during the collision, reducing the risk of bending or breaking of the rear bumper due to single-point stress.

[0020] The cross-sectional area of ​​the connecting rod is smaller than that of the rear bumper body. In the event of a collision, the rear bumper body acts as the first layer of buffer to absorb the impact force, while the connecting rod transfers the remaining energy to the sleeve through threaded engagement, which can effectively prevent the rear bumper body from breaking due to local stress concentration.

[0021] By incorporating weight-reduction holes in at least one of the rear bumper body and connecting rod, the weight of the protective structure can be significantly reduced, thus contributing to a lower vehicle weight. As the terminal structure of the exposed portion, the bumper protection section significantly enhances the rear bumper's impact resistance in a collision. The detachable design of the bumper protection section from the exposed portion allows users to replace only the damaged section when it is damaged, rather than replacing the entire rear bumper, thus reducing repair time and costs.

[0022] The axial direction of the threaded connector is consistent with the extension direction of the rear bumper, which facilitates the use of longer threaded connectors and improves the reliability of the installation of the bumper protection unit.

[0023] By partially inserting the exposed portion of the rear bumper guard into the first groove of the guardrail protection section, the rear bumper guard can be better protected, effectively preventing damage to the rear bumper guard when subjected to impact forces. A second groove is provided, and the head of the threaded connector is positioned within the second groove. This reduces the direct impact on the threaded connector due to its exposure, further preventing damage to the threaded connector. When maintenance is required, only the guardrail protection section needs to be replaced, which also helps reduce maintenance costs.

[0024] Another objective of this utility model is to provide a vehicle, which is a straddle-type vehicle, and the vehicle is provided with the protective structure described above.

[0025] The vehicle described in this utility model, by applying the aforementioned protective structure, offers significant advantages in collision safety due to the superior protection it provides for the vehicle and its occupants. It is particularly suitable for motorcycles with stringent performance and quality requirements. The detachable mounting bracket is mounted on the frame, and the mounting bracket and rear bumper are detachably connected. These detachable connection structures facilitate vehicle assembly, disassembly, and maintenance, and allow for compatibility with a wide range of vehicle models, thus possessing broad market application prospects.

[0040] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the description of the present application, it should be noted that the terms "upper", "lower", "inner", "back" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" can only be for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0042] In addition, in the description of the utility model, unless otherwise expressly limited, the terms "mounting", "connecting", "connection", "connector" should be understood broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with specific circumstances.

[0043] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0044] The motorcycle protection assembly is an indispensable safety guarantee component of the motorcycle, which can effectively play a role of blocking impact force or providing stable support when responding to various unexpected conditions such as slight scratches, severe impact and even vehicle rollover, thereby protecting the legs of the rider from harm in all directions, and also playing a certain protective role on the vehicle body to reduce the damage degree of the vehicle body in an accident.

[0045] At present, the bumper in the motorcycle protection assembly is mostly designed in an integral structure. From the overall appearance, it presents a complete annular shape, and is arranged symmetrically left and right with the center line of the vehicle width direction as the reference. The original intention of this design may be to pursue the stability of the structure and the regularity of the appearance, but in actual application, it exposes many drawbacks.

[0046] Specifically, when one side of the bumper is hit by external force, due to the characteristics of the integral structure, the impact force will be conducted through the overall structure, causing the corresponding deviation of the bumper on the other side. This deviation is not small and negligible, but it will obviously change the original position and shape of the bumper. For the driver, the position of the bumper after the deviation is extremely likely to come into accidental contact with the driver's legs, and in the moment of high-speed driving or accident, it is extremely likely to cause serious extrusion and collision injury to the legs, thereby posing a great threat to the life safety of the driver.

[0047] In addition to the safety hazard, the bumper with the integral structure also has other problems. From the weight aspect, it is designed in an annular shape, and the overall weight is relatively large, which not only increases the burden of the motorcycle itself, causes the vehicle to consume more energy to overcome the additional weight during driving, reduces fuel economy or battery endurance, but also the overweight bumper may affect the handling performance of the vehicle, so that the driver needs to exert more force when turning, accelerating and other operations, increasing the difficulty and fatigue of driving.

[0048] Moreover, when the bumper needs to be maintained or replaced due to damage, the entire bumper usually needs to be removed due to the integrated structure. This process is not only cumbersome and requires professional technicians and specific tools and equipment, but also may cause accidental damage to other parts of the vehicle during disassembly, increasing the difficulty and cost of maintenance. At the same time, replacing the entire bumper means that the consumer needs to pay a higher replacement cost, further increasing the economic burden.

[0049] Therefore, the present embodiment relates to a protective structure to improve the protection effect on the vehicle and the driver.

[0050] Based on the above design idea, an exemplary structure of the protective structure of the present embodiment in the application state is shown in Figure 1 Figure 1 The structure diagram of the structure without the exhaust pipe protective cover 4 is shown in Figure 2 The protective structure of the present embodiment is applied to a straddle-type vehicle with an exhaust pipe, and the overall structure mainly includes a mounting bracket 1 and a rear bumper 2 mounted on the mounting bracket 1.

[0051] The mounting bracket 1 is provided with a mounting portion A, which can connect the mounting bracket 1 to the frame of the vehicle, and the connection point between the mounting bracket 1 and the frame is located inside the exhaust pipe protective cover 4 in the vehicle. The rear bumper 2 is arranged through the exhaust pipe protective cover 4, and the rear bumper 2 has an exposed part 202 extending to the outside of the exhaust pipe protective cover 4.

[0052] It should be noted that the straddle-type vehicle in the present embodiment can be an existing fuel motorcycle. The protective structure of the present embodiment is preferably mounted on the right rear side of the vehicle. When the driver sits on the straddle-type vehicle to prepare for driving, the head of the vehicle is in front, the tail of the vehicle is in back, the side where the driver's left hand is located is the left side, and the side where the driver's right hand is located is the right side.

[0053] The mounting bracket 1 serves as a connecting piece between the rear bumper 2 and the frame, and the rationality of its installation position directly affects the overall stability of the rear bumper 2. In the above structure, the connection point of the mounting bracket 1 and the frame is designed inside the exhaust pipe protective cover 4. This layout not only utilizes the space of the original structure of the vehicle, but also prevents the collision risk that may be caused by external installation. For example, during vehicle driving, if the mounting point of the rear bumper 2 is directly exposed, it is easy to be affected by road obstacles or lateral impact. However, by hiding the mounting point inside the protective cover, the risk can be effectively reduced. In addition, if the mounting point of the rear bumper 2 is directly exposed, it will also affect the appearance of the vehicle.

[0054] ​The exposed portion 202 of the rear bumper 2 extends to the outside of the exhaust pipe guard 4. This design allows the rear bumper 2 to contact the collision object earlier when the vehicle is rear- ended, thereby absorbing and dispersing the collision energy. For example, when the vehicle is rear-ended by another vehicle, the rear bumper 2 of the exposed portion 202 can first bear the impact force and absorb part of the energy through its own deformation, reducing the damage to the vehicle and the occupants.

[0055] The design of the exposed portion 202 can also expand the protection range of the rear bumper 2, allowing it to cover more areas of the rear of the vehicle. This not only improves the protection capability of the rear of the vehicle, but also protects key components such as the exhaust pipe from damage to some extent.

[0056] The connection between the rear bumper 2 and the mounting bracket 1 can be detachable, making it easier to install and remove the rear bumper 2. For example, through screwing, clamping, etc., the rear bumper 2 can be easily removed or installed on the mounting bracket 1, thereby facilitating maintenance and replacement.

[0057] Due to the design of the exposed portion 202 of the rear bumper 2, it is easier to observe the damage when the vehicle is in a collision, and timely repair or replacement can be performed. This not only reduces maintenance costs and time, but also ensures that the vehicle always maintains good protection performance.

[0058] In order to facilitate overall arrangement, as a preferred embodiment, the vehicle frame has a side box bracket 3, and the mounting bracket 1 is detachably mounted on the side box bracket 3.

[0059] Since the side box bracket 3 is usually made of high-strength steel or aluminum alloy material, it can withstand large lateral and longitudinal loads. By fixing the mounting bracket 1 directly to the side box bracket 3, the structural strength can be fully utilized to improve the impact resistance of the rear bumper 2 in a collision and reduce the risk of damage to the vehicle frame structure.

[0060] The mounting bracket 1 is designed to be detachably mounted, allowing users or maintenance personnel to quickly disassemble and assemble the rear bumper 2 without the need for professional tools. For example, when the vehicle is in a collision and the rear bumper 2 is damaged, the user can directly remove the mounting bracket 1 from the side box bracket 3 and replace the new rear bumper, significantly shortening the repair time.

[0061] The rear bumper 2 and the side box bracket 3 are combined, and the rear bumper 2 first absorbs the impact energy in a collision, while the side box bracket 3 as a second line of defense can further disperse the remaining energy, significantly reducing the damage to key components such as the engine and exhaust pipe at the rear of the vehicle.

[0062] The traditional frame protection structure is annular as a whole and is symmetrically arranged about the width direction of the vehicle. Since the protection structure occupies a large space and is heavy, more mounting points are required to improve the firmness and reliability of the installation. The protection structure of the embodiment can be arranged on one side of the vehicle and can be installed through the existing side box support 3, thereby reducing secondary processing of the frame and saving manufacturing costs. For example, only two bolt mounting holes need to be reserved on the side box support 3.

[0063] The detachable installation mode can reduce the installation threshold, and users can choose whether to install the rear guard rod 2 or replace the style of the rear guard rod 2 according to individual needs such as riding scenes, aesthetic preferences, etc.

[0064] Users can select installation supports 1 and rear guard rods 2 made of different materials such as aluminum alloy and carbon fiber to achieve lightweighting while ensuring protection performance, and enhance the visual impact of the rear of the vehicle through the design of the exposed part 202.

[0065] As shown in Figure 3 and Figure 4 , as a preferred embodiment, the installation support 1 includes a sleeve 101 capable of inserting the rear guard rod 2, and installation plates arranged on both sides of the sleeve 101, wherein the installation plates on both sides are detachably connected with the side box support 3, and each installation plate is provided with the aforementioned connection point.

[0066] In the embodiment, the insertion hole in the sleeve 101 is preferably a threaded hole B, which facilitates connection with the rear guard rod 2 through screwing.

[0067] For convenience of description, the two installation plates on both sides of the sleeve 101 are referred to as a first installation plate 102 and a second installation plate 103. In the preferred embodiment, the first installation plate 102 is a bent plate, and the second installation plate 103 is a flat plate, and the installation part A includes an upper mounting hole formed in the flat plate and an upper mounting hole formed in the bent plate.

[0068] It should be noted that the two installation plates are respectively provided as a flat plate and a bent plate, which facilitates connection with the two sides of the side box support 3. As shown in Figure 3 , in the embodiment, the side box support 3 is provided with mounting holes on both sides, and the installation support 1 is connected with the side box support 3 through the mounting holes on the flat plate and the bent plate, for example, through bolts passing through the mounting holes to connect with the side box support 3, so that the side box support 3 is provided with the aforementioned connection point on both sides, which can improve the reliability of fixing the installation support 1 on the side box support 3.

[0069] In addition, the insertion structure of the sleeve 101 and the rear bumper 2 can form a central support point, and the two side mounting plates can form auxiliary support through the side box support 3, thereby forming a stable triangular stress system. This design can more evenly disperse the impact force during a collision and reduce the risk of bending or breaking of the rear bumper 2 due to single-point stress.

[0070] The sleeve 101 is inserted and connected with the rear bumper 2, and in combination with the constraint of the two side mounting plates, the torsional stiffness of the protection structure can be significantly enhanced. For example, when the vehicle is hit from the side, the sleeve 101 can prevent the rear bumper 2 from twisting and detaching, and the two mounting plates can transmit the lateral force to the vehicle frame through the side box support 3, effectively preventing local stress concentration.

[0071] The rear bumper 2 is inserted and connected with the mounting bracket 1 through the sleeve 101, so that the user can complete the replacement by simply pulling out the rear bumper 2. The detachable design of the mounting plate can further simplify the connection process with the side box support 3, thereby greatly shortening the maintenance time.

[0072] By unifying the inner diameter specifications of the sleeve 101, the rear bumper 2 can be adapted to different mounting brackets 1 of different vehicle models. For example, the manufacturer can provide rear bumpers 2 of different lengths or shapes, and the user can simply select a model that fits the sleeve 101 to complete the installation, without the need to develop a special rear bumper 2 for each vehicle model.

[0073] The insertion structure of the sleeve 101 and the rear bumper 2 can increase anti-disengagement structures such as locking pins, elastic buckles, etc., to prevent the rear bumper 2 from loosening and falling off due to vibration during driving. The two side mounting plates are independently connected to the side box support 3, so that even if one side mounting plate is damaged due to a collision, the other side can still provide support, thereby better ensuring that the rear bumper 2 does not detach from the vehicle frame and improving safety.

[0074] In order to facilitate connection with the mounting bracket 1, as a preferred embodiment, as shown in Figure 5 The rear bumper 2 includes a rear bumper body 201 and a connecting rod 203 arranged at one end of the rear bumper body 201 away from the exposed part 202, wherein the cross-sectional area of the connecting rod 203 is smaller than that of the rear bumper body 201, and the rear bumper 2 is connected with the sleeve 101 through screwing.

[0075] In a preferred embodiment, the rear bumper body 201 and the connecting rod 203 are both cylindrical in shape. It should be understood that the rear bumper body 201 and the connecting rod 203 can also be prismatic.

[0076] As defined in the above structure, the cross-sectional area of the connecting rod 203 is smaller than the rear bumper body 201, so that the inner diameter of the sleeve 101 can be reduced, facilitating the screwing of the connecting rod 203 with the sleeve 101. In the event of a collision, the rear bumper body 201 serves as the first layer of buffer to absorb the impact force, and the connecting rod 203 transmits the remaining energy to the sleeve 101 through the thread engagement, which can better prevent the rear bumper body 201 from being broken due to local stress concentration.

[0077] The rear bumper body 201 is designed with a large cross-section, which can provide high-strength support, while the connecting rod 203 is designed with a small cross-section, which allows it to undergo controllable deformation such as thread slipping or rod buckling under extreme loads, thereby dissipating more impact energy and better protecting the frame from damage.

[0078] The small cross-section design of the connecting rod 203 can also reduce the difficulty of screwing operation, and the user can complete the alignment and connection of the sleeve 101 and the connecting rod 203 with one hand in a narrow space such as the inside of the side box support 3 without visual assistance. For example, during maintenance, the technician can rotate the rear bumper body 201 with one hand to quickly complete the installation using the self-guiding function of the connecting rod 203.

[0079] The connecting rod 203 and the sleeve 101 are connected by screwing, and anti-loosening measures such as thread glue, locking nuts or elastic washers can be added between them to prevent screwing from loosening due to vibration during driving. For example, adhesive glue is applied to the surface of the thread to form a permanent bond between the connecting rod 203 and the sleeve 101, ensuring the stability of long-term use.

[0080] In a preferred embodiment, at least one of the rear bumper body 201 and the connecting rod 203 is provided with a weight-reducing hole, which can better reduce the weight of the rear bumper 2. In this embodiment, the rear bumper body 201 and the connecting rod 203 are both provided with a weight-reducing hole, for example, the rear bumper body 201 and the connecting rod 203 are both made of a pipe body, and each has a weight-reducing hole inside, which can further reduce the overall weight of the rear bumper 2.

[0081] It should be understood that one of the rear bumper body 201 and the connecting rod 203 can also be made of a pipe body. In addition, the weight-reducing holes on the rear bumper body 201 and the connecting rod 203 can of course also be provided in other shapes and numbers, for example, the weight-reducing holes are multiple, each weight-reducing hole is arranged along the radial direction of the rear bumper body 201, and the multiple weight-reducing holes are arranged in the axial direction of the rear bumper body 201.

[0082] In a preferred embodiment, still referring to Figure 5As shown, the rear bumper body 201 and the connecting rod 203 are both welded with a round plate. In order to improve the welding performance, grooves can be formed on the rear bumper body 201 and the connecting rod 203, so that the welding reliability can be improved by plug welding process. In order to facilitate the installation of the following bumper protection part 5, the end of the rear bumper body 201 away from the connecting rod 203 is also provided with a plug plate, and a connecting part for connecting with the bumper protection part 5 is arranged on the plug plate. In this embodiment, the connecting part is preferably a threaded connecting hole arranged on the plug plate.

[0083] By Figure 2 , Figure 3 in combination Figure 6 and Figure 7 As a preferred embodiment, the exposed part 202 is provided with a bumper protection part 5 at the part away from the mounting bracket 1, and the bumper protection part 5 is detachably mounted on the exposed part 202.

[0084] Here, the bumper protection part 5 serves as the terminal structure of the exposed part 202, which can significantly enhance the impact resistance of the rear bumper 2 in a collision. For example, in a low-speed rear-end collision, the bumper protection part 5 first bears the impact force, and absorbs energy through its own deformation or fracture, thereby reducing the risk of bending or breaking of the body of the exposed part 202 due to direct force.

[0085] The detachable design of the bumper protection part 5 and the exposed part 202 allows users to replace only the damaged bumper protection part 5 when the bumper protection part 5 is damaged, without the need to replace the entire rear bumper 2. For example, after a minor collision causes the bumper protection part 5 to deform, the user can quickly detach the old bumper protection part 5 and install a new one, greatly shortening the repair time and reducing maintenance costs.

[0086] By unifying the connection interface of the bumper protection part 5 and the exposed part 202, such as a buckle, a thread, etc., the bumper protection part 5 can be adapted to different models of rear bumpers 2. For example, manufacturers can provide bumper protection parts 5 of various shapes such as round, square, or different sizes, and users only need to select the model that fits the exposed part 202 to complete the installation.

[0087] The connection design of the bumper protection part 5 and the exposed part 202 can increase anti-loose measures such as double buckles, thread locking, etc., to prevent the bumper protection part 5 from loosening and falling off due to vibration during driving.

[0088] The standardized design of the bumper protection part 5 allows it to be mass-produced, reducing mold costs. For example, the same set of molds can be used to produce bumper protection parts 5 of various shapes and materials, reducing mold opening costs. The exposed part 202 does not need additional processing of the bumper protection part 5 installation structure, only needs to reserve a standardized interface, saving processing time.

[0089] Users can change the material of the bumper guard 5 according to their needs, such as rubber, plastic, metal, etc., and can also change the shape of the bumper guard 5, such as a streamlined or angular bumper guard 5. The standardized design of the exposed part 202 ensures compatibility.

[0090] In this embodiment, the cross-sectional area of ​​the guardrail protection part 5 gradually decreases from the end facing the mounting bracket 1 to the end away from the mounting bracket 1, which helps to improve the appearance quality. At the same time, the end with the smaller cross-sectional area contacts the ground first, which can also gradually transmit and dissipate the impact force, thus improving the impact resistance performance.

[0091] Reference Figure 2 , Figure 6 and Figure 7 As shown, in a preferred embodiment, the bumper protection part 5 is mounted on the exposed part 202 via a threaded connector 6, and the axial direction of the threaded connector 6 is consistent with the extension direction of the rear bumper 2.

[0092] The threaded connector 6 can be, for example, an existing bolt or screw. The axial direction of the threaded connector 6 is aligned with the extension direction of the rear bumper 2, allowing the installation torque to be directly transmitted along the axis of the rear bumper 2. This reduces the bending stress on the rear bumper 2 and the bumper protection part 5 caused by lateral forces. For example, during rapid acceleration or braking of the motorcycle, the axial force on the rear bumper 2 is evenly transmitted to the exposed part 202 through the threaded connector 6, avoiding localized stress concentration caused by the tilting of the threaded connector 6.

[0093] Meanwhile, the threaded connector 6 is aligned axially with the extension direction of the rear bumper 2, which can make full use of the installation space and improve the reliability of fixing the bumper protection part 5. For example, the length of the threaded connector 6 can be set to be relatively long, which helps to improve the connection strength between the threaded connector 6 and the rear bumper 2.

[0094] In a preferred embodiment, an anti-loosening structure is provided between the threaded connector 6 and the rear bumper 2. For example, an anti-loosening coating such as a thread-locking agent is added to the contact surface between the threaded connector 6 and the exposed part 202, or a threaded connector 6 with a self-locking function is used to prevent loosening due to vibration during vehicle operation.

[0095] In a preferred embodiment, the first end of the guardrail protection part 5 is provided with a first groove 501, and a portion of the exposed part 202 is inserted into the first groove 501.

[0096] The first groove 501 is inserted into the exposed portion 202, and when impact force is borne, the outer force is mainly borne by the bumper protection part 5, so that better protection can be formed on the rear bumper 2. The contact surface of the exposed portion 202 and the first groove 501 can form a local stress concentration area, which can preferentially absorb impact energy in a collision. For example, the bottom of the first groove 501 can be designed as a circular arc transition, so that the impact force is uniformly dispersed along the side wall of the first groove 501, which can reduce the risk of bending of the exposed portion 202.

[0097] By adjusting the depth, width or shape of the first groove 501, the bumper protection part 5 can be adapted to different diameters or cross sections of the exposed portion 202. The insertion structure of the first groove 501 and the exposed portion 202 can be combined with other fixing methods such as screwing, clamping, etc. to form a double anti-disengagement mechanism. For example, an inner thread is arranged on the side wall of the first groove 501, and an outer thread can be arranged on the exposed portion 202 of the rear bumper 2, which facilitates screwing connection with the bumper protection part 5 and effectively prevents the bumper protection part 5 from falling off due to vibration during driving.

[0098] Continuing to refer to Figure 2 , Figure 6 and Figure 7 , as a preferred embodiment, the second end of the bumper protection part 5 is provided with a second groove 502, and the head of the threaded connecting piece 6 is embedded in the second groove 502.

[0099] Specifically, still referring to Figure 6 and Figure 7 , the inside of the bumper protection part 5 is provided with a through hole, and a partition plate 503 is arranged in the through hole, which divides the through hole into the first groove 501 and the second groove 502 on both sides of the partition plate 503. The partition plate 503 is also provided with a through hole for the threaded connecting piece 6 to pass through, which facilitates the fixation of the bumper protection part 5 on the rear bumper 2.

[0100] The second groove 502 is arranged, and the head of the threaded connecting piece 6 is arranged in the second groove 502, which is beneficial to reduce the direct impact on the threaded connecting piece 6 due to exposure. For example, in a collision accident, the bumper protection part 5 can preferentially absorb impact force, avoiding the breakage of the threaded connecting piece 6 due to uneven force, and when maintenance is needed, only the bumper protection part 5 can be replaced, which is beneficial to reduce maintenance cost, and also reduces the risk of the threaded connecting piece 6 hooking other objects. As a preferred embodiment, the exposed portion 202 is provided with a clamping portion 2021 for clamping by an external tool.

[0101] In a preferred embodiment, the clamping portion 2021 includes clamping surfaces arranged on opposite sides of the exposed portion 202, and the rear bumper 2 can be conveniently screwed to the mounting bracket 1 by clamping the clamping surfaces on both sides by an external tool.

[0102] In a preferred embodiment, the clamping portion 2021 is located at the portion of the exposed portion 202 embedded in the first groove 501, so that after the installation of the guard 5, the clamping surface is prevented from being exposed, thereby improving the appearance quality of the protection structure.

[0103] The contact surface of the clamping portion 2021 with the tool, such as the aforementioned clamping surface, can be provided with anti-skid texture or magnetic structure to prevent the tool from slipping during operation. For example, a plurality of anti-skid protrusions can be provided on the clamping surface to increase the friction between the tool and the clamping portion 2021.

[0104] As a preferred embodiment, the rear guard 2 extends along the width direction of the vehicle and is located above the exhaust pipe, and the rear guard 2 is arranged close to the exhaust pipe.

[0105] It should be noted that the exhaust pipe is not shown in the figure. In this structure, the extension direction of the rear guard 2 is along the vehicle width direction, so that the rear guard 2 has a shorter size and a lighter weight, and can achieve a better protection effect. When arranging the rear guard 2, the rear guard 2 should be arranged as low as possible, so that the shorter rear guard 2 can achieve a better protection effect.

[0106] In a preferred embodiment, a vibration isolation pad such as a rubber buffer can be provided between the rear guard 2 and the exhaust pipe, which can better prevent the transmission of exhaust system vibration to the vehicle body and prevent contact noise between the two.

[0107] As a preferred embodiment, a sealing portion is provided between the exhaust pipe guard 4 and the rear guard 2 to seal the gap therebetween.

[0108] For example, the sealing portion in the present embodiment can be a sealing ring, which has elastic deformation capability and can be made of EPDM rubber or TPU material, so that the opening 401 on the exhaust pipe guard 4 is smaller and has a more delicate appearance, and can better prevent impact between the exhaust pipe guard 4 and the rear guard 2, thereby preventing abnormal noise.

[0109] The protection structure of the present embodiment has the connection point between the mounting bracket 1 and the vehicle frame located on the inner side of the exhaust pipe guard 4, and the rear guard 2 extends from the connection point to the outer side of the exhaust pipe guard 4, which can reduce the risk of overall displacement of the existing frame-type protection device damaging the driver's legs, and through the arrangement of the exposed portion 202, the exhaust pipe guard 4 can be prevented from being damaged when the vehicle falls, and the exhaust pipe guard 4 and the driver can be better protected, thereby improving the protection effect on the vehicle and the driver.

[0112] The vehicle of the embodiment has the same beneficial effects as the protective structure of the embodiment one relative to the prior art.

[0113] The mounting bracket 1 is detachably mounted on the frame, and the mounting bracket 1 and the rear bumper 2 are detachably connected, the detachable connection structure is convenient to disassemble and maintain, can be adapted to more vehicle models, and has wide market application prospects.

[0114] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
