Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an enhanced structure for the heat dissipation fins of a car rear lip. Background Technology

[0002] The rear lip, as the lower edge component of the rear bumper, plays an important role in modern car design. It is not only an extension of the body shape, used to enhance the sportiness and aesthetics of the vehicle, but also has a preliminary guiding effect on the aerodynamic performance of the rear of the car.

[0003] The area where the rear lip of a car is located is adjacent to the vehicle's exhaust system, especially the end of the exhaust pipe. During vehicle operation, the exhaust system produces a large amount of high-temperature exhaust gas, causing the temperature of the exhaust pipe itself and the interior space of the rear lip to rise sharply. Existing rear lip components are decorative covers made of plastic or carbon fiber, which have a relatively closed structure and lack effective heat dissipation design.

[0004] This continuous heat buildup can not only cause the rear lip component itself to deform, age, or be damaged due to high temperatures, but also pose safety hazards to other components around the exhaust pipe. In addition, some vehicles install rear lip fins or diffusers in pursuit of a sporty appearance, but these components often only focus on visual effects or a single aerodynamic function. They themselves do not have heat dissipation capabilities and fail to form an effective reinforced connection with the vehicle body structure, making them prone to loosening or damage under high-speed driving or bumpy road conditions.

[0005] Therefore, this utility model proposes an enhanced structure for the heat dissipation fins of the rear lip of an automobile to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing automotive rear lip structures, such as limited functionality, inability to simultaneously address efficient heat dissipation of the exhaust system, effective management of exhaust airflow, and structural reinforcement requirements of the rear lip components themselves, this utility model aims to provide an improved automotive rear lip heat dissipation fin reinforcement structure that can effectively solve the above problems.

[0007] This utility model provides a finned heat dissipation structure for a car rear lip, including an outer shell and a rear shell mounted on the rear side of the outer shell. A crossbeam is fixedly connected between the two rear shells. Support rod 1 and support rod 2 are symmetrically fixedly connected to the top surface of the crossbeam. A heat dissipation mesh is tautly fixed between support rod 1 and support rod 2. Ribs are also provided at the connection between the crossbeam and the rear shell. A composite mechanism is provided on the outer shell, and a heat dissipation port for the exhaust pipe to pass through is provided on the composite mechanism. Heat-conducting fin 1 and heat-conducting fin 2 are fixedly connected to the inner wall of the heat dissipation port. A guide vane is fixedly connected to the bottom side of the outer shell. Fin 1 and fin 2 are fixedly connected to the guide vane. A honeycomb sandwich layer 1 is provided inside fin 1, and a honeycomb sandwich layer 2 is provided inside fin 2. A turbulence diffuser is also provided on the guide vane. The turbulence diffuser is fixed to the guide vane by a connecting piece, and the turbulence diffuser includes multiple fins.

[0008] Preferably, support rod one and support rod two are used to support the heat dissipation mesh upwards. The heat dissipation mesh is located directly above the crossbeam and is used to dissipate heat from inside the rear lip.

[0009] Preferably, the reinforcing rib is an L-shaped reinforcing rib, with one end fixedly connected to the bottom surface of the crossbeam and the other end fixedly connected to the inner side wall of the rear shell, in order to enhance the anti-bumping ability of the connection.

[0010] Preferably, the heat-conducting plate one and the heat-conducting plate two are symmetrically arranged along the circumferential direction of the heat dissipation port, and the heat-conducting plate one and the heat-conducting plate two together form a clamping structure for conducting heat while fixing the exhaust pipe.

[0011] Preferably, the spoiler diffuser is fixed to the outer trailing edge of the guide vane by a connecting piece. This fixing method using a connecting piece is used to prevent the spoiler diffuser from fluttering under high-speed airflow.

[0012] Preferably, multiple vanes are arranged at intervals along the width direction of the guide vane, and these vanes are used to help optimize the airflow at the rear of the vehicle and improve heat dissipation efficiency.

[0013] Preferably, fin one and fin two are symmetrically arranged on both sides of the top surface of the guide vane, and the honeycomb interlayer one and honeycomb interlayer two inside it are used to disperse the force on fin one and fin two.

[0014] Preferably, both the first and second honeycomb sandwich layers have honeycomb channels that penetrate the front and rear edges of the fins. The axial direction of these honeycomb channels is parallel to the vehicle's driving direction, thus forming an auxiliary heat dissipation channel.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problems of simple heat dissipation structure of the rear lip of automobiles and difficulty in dissipating heat from the exhaust pipe in the prior art by setting up a heat dissipation mesh for dissipating internal heat, a heat-conducting sheet for conducting high temperature of the exhaust pipe, and a honeycomb interlayer for auxiliary heat dissipation channel, thereby achieving efficient composite heat dissipation of the rear of the vehicle.

[0017] 2. This utility model solves the problems of chaotic airflow at the rear of the vehicle, lack of downforce, and easy flutter at high speeds in the prior art by setting up a turbulence diffuser, guide vanes, winglets, and connecting pieces for stable connection. It optimizes the airflow under the vehicle, significantly enhances the downforce at the rear of the vehicle, and improves the stability at high speeds.

[0018] 3. This utility model solves the problem that the existing fin structure is difficult to balance lightweight, structural strength and buffer performance by setting a honeycomb interlayer inside the fin. It achieves structural weight reduction, disperses the force on the fin and buffers the impact, and also serves as an auxiliary heat dissipation channel. Attached Figure Description

[0026] Example:

[0027] Please refer to Figures 1 to 4 This utility model provides a reinforced structure for the heat dissipation fins of a car rear lip, which aims to solve the technical problems of insufficient heat dissipation capacity, large airflow interference, and difficulty in balancing lightweight and structural strength in existing car rear lip structures.

A heat conduction plate 202 and a heat conduction plate 203 are fixedly connected to the inner wall of the heat dissipation port 201. The guide vane 11 is fixedly connected to the bottom side of the outer shell 1.

[0030] like Figure 3 As shown, a turbulence diffuser 10 is provided on the guide vane 11. The turbulence diffuser 10 is fixed to the guide vane 11 by a connecting piece 9. The turbulence diffuser 10 includes multiple blades 204.

[0031] like Figure 4 As shown, fin 1 205 and fin 2 207 are also fixedly connected to the guide vane 11. The interior of fin 1 205 is provided with honeycomb interlayer 206, and the interior of fin 2 207 is provided with honeycomb interlayer 208.

[0032] Please refer to Figure 2 Support rod 4 and support rod 5 are symmetrically fixed to the top surface of the crossbeam 6 to support the heat dissipation mesh 7 located directly above the crossbeam 6. The heat dissipation mesh 7 is taut and fixed between support rod 4 and support rod 5 to form a channel for directly dissipating the heat accumulated inside the rear lip.

[0033] To enhance the stability of the overall structure, the rib 8 is set as an L-shaped reinforcing rib. One end of the rib 8 is fixedly connected to the bottom surface of the crossbeam 6, and the other end is fixedly connected to the inner side wall of the rear shell 3. Through this triangular stabilizing structure, the anti-bump and anti-vibration ability of the connection between the crossbeam 6 and the rear shell 3 is effectively improved.

[0034] Please refer to Figure 1 The composite mechanism 2 is disposed on the outer shell 1. The composite mechanism 2 has a heat dissipation port 201 through which the exhaust pipe passes. On the inner wall of the heat dissipation port 201, the heat-conducting plate 1 202 and the heat-conducting plate 203 are symmetrically arranged along the circumferential direction of the heat dissipation port 201. The heat-conducting plate 1 202 and the heat-conducting plate 203 form a clamping structure, which can fit tightly and clamp and fix the exhaust pipe during installation, so as to realize the rapid conduction and dissipation of heat from the exhaust pipe.

[0035] Please refer to Figure 3 In a preferred embodiment, the turbulence diffuser 10 is fixed to the outer side of the trailing edge of the guide vane 11 by a connecting piece 9; the connecting piece 9 prevents the turbulence diffuser 10 from fluttering under high-speed airflow.

[0036] Furthermore, multiple vanes 204 are arranged at intervals along the width direction of the guide vane 11; the vanes 204 help optimize the airflow at the rear of the vehicle and improve heat dissipation efficiency.

[0037] Please refer to Figure 4 In another preferred embodiment, fin one 205 and fin two 207 are symmetrically arranged on both sides of the top surface of the guide vane 11; honeycomb interlayer one 206 and honeycomb interlayer two 208 disperse the force on fin one 205 and fin two 207.

[0038] Furthermore, both the first honeycomb interlayer 206 and the second honeycomb interlayer 208 have honeycomb channels that penetrate the front and rear edges of the fins; the axial direction of the honeycomb channels is parallel to the vehicle's driving direction and forms an auxiliary heat dissipation channel.

[0039] Working principle: During installation, the outer shell 1 and the rear shell 3 installed on the rear side of the outer shell 1 are fixed to the rear lip of the vehicle. The crossbeam 6 is fixedly connected between the two rear shells 3. The ribs 8 set at the connection between the crossbeam 6 and the rear shell 3 are L-shaped reinforcing ribs, which are used to strengthen the overall structure and enable the ribs 8 to adapt to the bumps during driving.

[0040] Support rod 4 and support rod 5, symmetrically fixed to the top surface of the crossbeam 6, support the heat dissipation mesh 7 upwards. The heat dissipation mesh 7 is located directly above the crossbeam 6, providing a main heat dissipation channel for the interior of the rear lip. At the same time, the exhaust pipe passes through the heat dissipation port 201 on the composite mechanism 2. The heat-conducting plates 202 and 203, symmetrically arranged along the circumference of the heat dissipation port 201, form a clamping structure, tightly fixing the exhaust pipe and actively conducting its high temperature, thus achieving direct heat dissipation of the exhaust pipe. The guide vane 11, fixedly connected to the bottom side of the outer shell 1, serves as the base. The fins 205 and 207, fixedly connected to the guide vane 11, can help optimize the airflow at the rear of the vehicle and reduce wind resistance. The spoiler diffuser 10, which is set on the guide vane 11, contains multiple spaced fins 204, which can efficiently manage the airflow under the vehicle, enhance the downforce at the rear of the vehicle, and improve high-speed driving stability. The connecting piece 9 fixes the spoiler diffuser 10 to the guide vane 11, preventing the component from vibrating under high-speed airflow.

[0041] The honeycomb interlayer 206 inside fin 1 and the honeycomb interlayer 208 inside fin 207 not only disperse the stress on the fins, achieving structural lightweighting and buffering, but also allow airflow to pass through the honeycomb channels that run through the front and rear edges of fin 1 205, forming an auxiliary heat dissipation channel and further improving the overall heat dissipation performance.
