A cockpit bulkhead assembly that is easy to disassemble and cushion

Abstract

This utility model relates to the field of automotive device technology, and in particular to a cockpit baffle assembly that is easy to install and remove and provides cushioning. It includes a baffle body with heat dissipation holes, and an outer protective plate with a recessed internal structure. The outer and inner protective plates form an installation cavity, within which several spring dampers are installed. The outer protective plate is slidably connected to the inner protective plate. When the baffle body is subjected to impact, the outer protective plate first absorbs the force through its own deformation, thus buffering the external force and converting instantaneous hard impacts into slow deformation forces. This avoids localized stress concentration that could damage the protective plate, improving the overall durability of the baffle body and preventing impact damage. Simultaneously, it utilizes sound-absorbing cotton to reduce noise energy generated inside the engine compartment, preventing low-frequency noise from causing discomfort to the driver.

Description

Technical Field

[0001] This utility model relates to the field of automotive device technology, and in particular to a cockpit baffle assembly that is easy to disassemble and buffer. Background Technology

[0002] Wiring harnesses are typically integrated into the footwell of a car's driver's compartment. To prevent damage to these harnesses and accidental kicking during driving, protective covers are usually installed at the footwell. However, existing car foot covers often use a single piece with a simple clip structure. While this simple structure can directly shield the internal wiring harness, in actual use, the driver's foot can easily kick the cover, causing impact. Furthermore, the cover is susceptible to damage from external objects. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cockpit baffle assembly that is easy to disassemble and buffer. It solves the technical problems of existing baffles having simple structures and being easily damaged by impacts from external objects. It avoids damage to the baffle caused by local stress concentration, improves the overall durability of the baffle body, and prevents impact damage to the baffle body.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cockpit baffle assembly that is easy to disassemble and buffer, comprising a baffle body with heat dissipation holes, the baffle body comprising an outer protective plate with a recessed internal structure, an inner protective plate with a recessed internal structure provided on one side of the outer protective plate, and an elastic mounting plate fixedly installed on the side of the inner protective plate that contacts the outer protective plate, the elastic mounting plate mounting the baffle body under the foot of the car cockpit; The outer protective plate is slidably connected to the inside of the inner protective plate, and an installation cavity is formed between the outer protective plate and the inner protective plate. Several spring dampers are installed inside the installation cavity, and the installation cavity is filled with sound-absorbing cotton.

[0005] Preferably, the elastic mounting plate is integrally injection molded from a polymer composite material with preset strength and high toughness.

[0006] Preferably, the heat dissipation holes are formed through the surfaces of the outer protective plate and the inner protective plate, and the heat dissipation holes at the outer protective plate and the inner protective plate are correspondingly provided; A heat dissipation plate is fixedly installed between the outer protective plate and the inner protective plate. The heat dissipation plate has a heat dissipation channel with the same shape as the heat dissipation hole inside. Both ends of the heat dissipation plate are respectively connected to the heat dissipation holes of the outer protective plate and the inner protective plate.

[0007] Preferably, one end of the heat sink is fixedly connected to the outer protective plate, and the other end of the heat sink is fixedly installed with a limiting plate through the heat dissipation hole in the inner protective plate.

[0008] Preferably, the two ends of the spring damper are fixedly connected to the inner walls of the outer protective plate and the inner protective plate, respectively.

[0009] Preferably, the outer protective plate is a hollow sandwich structure, and several reinforcing ribs are fixedly installed inside the sandwich.

[0010] By employing the above technical solution, this utility model provides a cockpit baffle assembly that is easy to disassemble and install, and provides cushioning, and has at least the following beneficial effects: 1. This utility model forms an installation cavity by means of an outer protective plate and an inner protective plate. Several spring dampers are installed in the cavity. The outer protective plate is slidably connected to the inside of the inner protective plate. When the main body of the baffle is subjected to impact, the outer protective plate first relieves the force through its own deformation, which can buffer the force generated by the external force and convert the instantaneous hard impact into a slow deformation force. This avoids the situation where local stress concentration leads to damage to the protective plate, improves the overall durability of the main body of the baffle, and avoids the impact from damaging the main body of the baffle. At the same time, it can use sound-absorbing cotton to weaken the noise energy generated inside the engine compartment and avoid low-frequency noise from causing discomfort to the driver.

[0011] 2. This utility model features heat dissipation holes corresponding to the outer and inner protective plates, forming a directional heat dissipation channel through the connection of heat dissipation plates. One end of the heat dissipation plate is fixed to the outer protective plate, and the other end passes through the inner protective plate and is equipped with a limiting plate. The heat dissipation channel can guide the natural airflow of the cockpit to pass through, reduce the temperature around the wiring harness, and prevent the wiring harness from aging due to heat accumulation. When the heat dissipation plate slides with the outer protective plate, the limiting plate can prevent the heat dissipation plate from falling off, ensuring that the heat dissipation channel is always unobstructed and solving the problem of heat accumulation in the wiring harness.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Given the current limitations of simple baffle structures, which make them susceptible to impact from external objects and prone to damage, this embodiment provides a cockpit baffle assembly that is easy to disassemble and buffer. This assembly avoids damage caused by localized stress concentration, improves the overall durability of the baffle, and prevents impact-induced damage. Please refer to... Figure 1 - Figure 5 This easy-to-install and buffer cockpit baffle assembly includes a baffle body 1 with heat dissipation holes 2. The overall appearance of the baffle body 1 is not affected, thus improving its aesthetics. The baffle body 1 includes an outer protective plate 11 with a recessed internal structure, and an inner protective plate 12 with a recessed internal structure is provided on one side of the outer protective plate 11. An elastic mounting plate 13 is fixedly installed on the side of the inner protective plate 12 that contacts the outer protective plate 11. The elastic mounting plate 13 installs the baffle body 1 under the foot area of ​​the car's cockpit. Before use, the baffle body 1 is first installed under the foot area of ​​the driver and passenger seats to cover the wiring harness at the accelerator, preventing the driver from accidentally kicking the wiring harness and causing unnecessary damage. During use, when the baffle body 1 is subjected to external forces, the outer protective plate 11 absorbs the force first, and the inner protective plate 12 is connected to the outer protective plate 11 through a spring damper 3, so that the inner protective plate 12 only bears the low-energy force after damping attenuation.

[0017] Existing footrest covers for the cockpit are all in the form of panels. While they can directly cover the wiring harness around the accelerator pedal, in actual use, the driver's foot can easily kick the cover, causing impact. Furthermore, the cover is susceptible to damage from external objects. To address these issues, such as... Figure 2 - Figure 3As shown, the outer protective plate 11 is slidably connected to the inner protective plate 12, forming an installation cavity between the outer protective plate 11 and the inner protective plate 12. Several spring dampers 3 are installed inside the installation cavity, which is also filled with sound-absorbing cotton 4. The sound-absorbing cotton 4 is made of high-density polyester fiber sound insulation cotton. When the engine generates noise inside the engine compartment, the high-density polyester fiber sound insulation cotton can absorb low-frequency noise. Through the vibration damping effect of the air within the pores, it can effectively weaken the energy of low-frequency noise, preventing discomfort to the driver caused by low-frequency noise. The main body 1 of the baffle is connected to the outer protective plate 11. The inner protective plate 12 and the elastic mounting plate 13 are combined. The elastic mounting plate 13 can be used to easily snap the baffle body 1 onto the cover plate under the driver's compartment of the car. It should be noted that the existing baffles are all installed using the above method, which can improve the ease of installation of the baffle body 1. At the same time, by forming an installation cavity between the outer protective plate 11 and the inner protective plate 12 and installing several spring dampers 3 inside, the outer protective plate 11 can buffer the force generated by the outside world, converting the instantaneous hard impact into a slow deformation force, and avoiding the situation where the protective plate is damaged due to local stress concentration.

[0018] Specifically, such as Figure 2 As shown, the elastic mounting plate 13 is integrally injection molded from a high-molecular composite material with preset strength and high toughness. The high-molecular composite material is selected from polypropylene-based materials, which have certain impact strength and toughness, ensuring that the elastic mounting plate 13 can produce reversible elastic deformation when it is snapped into the cockpit foot cover. It also does not undergo permanent deformation or brittleness after repeated disassembly and assembly, and resists the stepping force and vibration impact of the foot area, avoiding the mounting plate from breaking or snapping failure.

[0019] Example 2 Based on Example 1, such as Figure 1 - Figure 5As shown, while ensuring that the baffle body 1 shields the wire harness, the device is also equipped with heat dissipation holes 2 to ensure normal heat dissipation inside the wire harness. These holes 2 penetrate the surfaces of the outer protective plate 11 and the inner protective plate 12, with corresponding heat dissipation holes 2 on the outer and inner protective plates 11 and 12. A heat dissipation plate 21 is fixedly installed between the outer and inner protective plates 11 and 12. The heat dissipation plate 21 forms a heat dissipation channel with the same shape as the heat dissipation holes 2 inside, and both ends of the heat dissipation plate 21 are respectively connected to the heat dissipation holes 2 on the outer and inner protective plates 11 and 12. The connection is achieved by opening heat dissipation holes 2 on the surfaces of the outer protective plate 11 and the inner protective plate 12. In order to ensure that the heat inside the baffle body 1 can be discharged through the heat dissipation holes 2, the heat dissipation holes 2 at corresponding positions of the outer protective plate 11 and the inner protective plate 12 are connected by a heat dissipation plate 21, so that a heat dissipation channel is formed between the outer protective plate 11 and the inner protective plate 12. This creates a directional heat dissipation path for the wiring harness in the foot area of ​​the cockpit, so that the heat can be accurately discharged from the inside to the outside of the baffle body 1 through the heat dissipation channel, avoiding heat accumulation and aging of the wiring harness and reducing safety hazards.

[0020] While ensuring normal heat dissipation, in order not to affect the sliding action of the outer protective plate 11, such as Figure 3 - Figure 4 As shown, one end of the heat sink 21 is fixedly connected to the outer protective plate 11, and the other end of the heat sink 21 is fixedly installed with a limiting plate 22 through the heat dissipation hole 2 in the inner protective plate 12. When the outer protective plate 11 is subjected to external impact force, the outer protective plate 11 slides into the inner protective plate 12 with the cooperation of multiple spring dampers 3. At the same time, it can drive the heat sink 21 to slide inside the inner protective plate 12. The heat sink 21 will drive the limiting plate 22 to extend and retract towards the inside of the baffle body 1, so that the installation of the heat sink 21 will not affect the normal sliding of the outer protective plate 11.

[0021] To improve the overall support strength of the outer protective plate 11, such as Figure 6 As shown, the two ends of the spring damper 3 are fixedly connected to the inner walls of the outer protective plate 11 and the inner protective plate 12, respectively. The outer protective plate 11 is a hollow sandwich structure, and several reinforcing ribs 111 are fixedly installed inside the sandwich. By installing multiple reinforcing ribs 111 inside the outer protective plate 11, the overall strength of the outer protective plate 11 can be improved. Compared with a solid plate, the impact resistance of the outer protective plate 11 can be improved, while the weight of the outer protective plate 11 can be reduced.
