[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the scope of protection of this utility model.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0052] To better understand the solution of this utility model, the relevant terms involved in this utility model will be explained below.

[0053] A loudspeaker is a sound-producing device in a vehicle used to play sound.

[0054] A power amplifier amplifies the weak signal input from audio equipment to generate a sufficiently large current to drive the speakers to reproduce sound. However, if the power amplifier's cooling is inadequate, excessively high temperatures can degrade its performance, leading to a decrease in the sound quality of the speakers.

[0055] Power amplifiers are typically located on the floor under the driver and front passenger seats, or on the floor of the trunk. However, placing them under the driver or front passenger seats can reduce the usable space under the seats, making it difficult for rear passengers to stretch their legs forward, resulting in a poor riding experience. The carpet may also wear down the wiring harness, and the power amplifier's heat dissipation will be affected by the carpet cover. Adding ventilation holes to the carpet to improve heat dissipation can also affect aesthetics. On the other hand, placing them on the trunk floor will encroach on trunk storage space, reducing the product's competitiveness. Furthermore, since the infotainment system is generally located at the front of the vehicle, the wiring harness from the power amplifier to the infotainment system will be longer, increasing costs.

[0056] The seat controller is the "brain" that manages the various functions of the electric seat. It is part of the vehicle's electronic control system and is responsible for receiving commands, driving the motor, and monitoring the seat status. Its core functions include command parsing and execution, position memory and linkage, and fault diagnosis and protection.

[0057] To better understand the protective component of this invention, an example of a vehicle in which the protective component is applied will be used.

[0058] like Figure 1 as well as Figure 2As shown, in some embodiments of this disclosure, a vehicle 1 is provided, including a body 10, a speaker (not shown), a power amplifier 30, and a front floor assembly 20. The speaker is fixed to the body 10 and is communicatively connected to the power amplifier 30.

[0059] like Figures 2 to 6 As shown, the front floor assembly 20 is fixedly connected to the vehicle body 10. The front floor assembly 20 includes a protective component 21, a front floor 22, and a front bulkhead 23 fixedly connected to the front floor 22. The protective component 21 includes a protective heat dissipation plate 100 for fixing between the front floor 22 and the front bulkhead 23. The protective heat dissipation plate 100 includes a first plate body 110, a second plate body 120, and a third plate body 130. The first plate body 110 includes a first side portion 111, a second side portion 112 spaced from the first side portion 111 along the length direction of the protective heat dissipation plate 100, and a first connecting portion 113 fixedly connected to the front floor 22. Along the thickness direction of the front floor 22, the second side portion 112 is disposed above the first side portion 111. The first connecting portion 113 is disposed between the first side portion 111 and the second side portion 112. One side of the second plate 120 is fixedly connected to the second side portion 112, so that the first plate 110 and the second plate 120 cooperate to form a heat dissipation space 101 required for protecting the power amplifier 30. The third plate 130 is fixedly connected to the other side of the second plate 120, and the third plate 130 is provided with a second connecting portion 131 fixedly connected to the front panel 23. The front floor 22 is provided with a first fixing portion 22a, which is fixedly connected to the first connecting portion 113, so that the front floor 22 covers the heat dissipation space 101. The front panel 23 is provided with a second fixing portion 23a, which is fixedly connected to the second connecting portion 131. The power amplifier 30 is fixedly connected to the front floor 22, and the power amplifier 30 is disposed in the heat dissipation space 101 and spaced apart from the second plate 120.

[0060] During vehicle assembly, the front lower floor assembly is fixedly connected to the vehicle body 10, so that the front floor 22 is located at the bottom of the vehicle body 10, and the front bulkhead 23 is located at the front of the vehicle body 10, thus creating an installation space on the vehicle body 10. A speaker is fixed to the vehicle body 10, and a power amplifier 30 is fixed to the front floor 22 and connected to the speaker, integrating the speaker and power amplifier 30 onto the vehicle body 10. A protective heat sink 100 is then fixed between the front floor 22 and the front bulkhead 23 via a first connecting part 113 and a first fixing part 22a, and a second connecting part 131 and a second fixing part 23a, facilitating full utilization of the bending space between the front floor 22 and the front bulkhead 23 to install electronic components such as the power amplifier 30, thereby improving the space utilization rate of vehicle 1. Because the first side 111 of the protective heat sink 100 is positioned close to or against the front floor 22, and the power amplifier 30 is protected through the heat dissipation space 101 formed by the first plate 110 and the second plate 120, the power amplifier 30 is effectively protected, and the required heat dissipation space 101 for the power amplifier 30 is increased, thereby improving the heat dissipation effect of the power amplifier 30. Thus, even after the vehicle 1's speakers have played sound for an extended period, the stability of the sound quality can be guaranteed.

[0061] In addition, the protective heat sink 100 has good heat dissipation function, which allows the heat generated by the power amplifier 30 to be transferred to the protective heat sink 100 for heat dissipation, indirectly increasing the heat dissipation area of ​​the power amplifier 30, thereby further improving the heat dissipation performance of the power amplifier 30 and improving the stability and reliability of the speaker.

[0062] like Figure 2 As shown, the thickness direction of the front floor 22 is the Z-axis direction. Figure 6 As shown, the length direction of the protective heat dissipation plate 100 is the X-axis direction.

[0063] It should be noted that there are various ways to achieve the fixed connection between the first connecting part 113 and the first fixing part 22a, including but not limited to screw fixing, riveting fixing, adhesive fixing, welding fixing, snap fixing, etc. In some embodiments, the front floor 22 is provided with a mounting base, and the mounting base is provided with a screw for forming the first fixing part 22a. Correspondingly, the first connecting part 113 is provided with a nut that is screwed into the screw. In this way, it is easy to achieve a detachable connection between the front floor 22 and the protective heat dissipation plate 100.

[0064] It should be noted that there are various ways to fix the power amplifier 30 to the front floor 22, including but not limited to screw fixing, riveting fixing, adhesive fixing, welding fixing, snap fixing, etc. In some embodiments, the front panel 23 is provided with a mounting base, and the mounting base is provided with a screw. Correspondingly, the power amplifier 30 is provided with a through hole that mates with the screw, thereby facilitating the detachable connection of the power amplifier 30 to the front floor 22 by screwing a nut onto the screw.

[0065] It should be noted that there are various ways to achieve the fixed connection between the second connecting part 131 and the second fixing part 23a, including but not limited to screw fixing, riveting fixing, adhesive fixing, welding fixing, snap fixing, etc. In some embodiments, the front panel 23 is provided with a mounting seat, and the mounting seat is provided with a screw for forming the second fixing part 23a. Correspondingly, the second connecting part 131 is provided with a nut that is screwed into the screw. In this way, it is easy to achieve a detachable connection between the front panel 23 and the protective heat dissipation plate 100.

[0066] It should be noted that there are various ways to fix the vehicle body 10 to the front floor 22 and the front bulkhead 23, including but not limited to screw fixing, riveting fixing, adhesive fixing, welding fixing, snap fixing, etc. In some embodiments, the vehicle body 10 is welded to the front floor 22 and the front bulkhead 23.

[0067] In some embodiments, the protective heat sink 100 is made of metal. This helps to ensure both the heat dissipation and protective performance of the protective heat sink 100.

[0068] Optionally, the material of the protective heat sink 100 is aluminum alloy and / or stainless steel, etc.

[0069] like Figure 2 as well as Figure 4 As shown, in some embodiments, the second plate 120 is provided with a perforated hole 121 communicating with the heat dissipation space 101. In this way, by providing the perforated hole 121, the weight of the protective heat dissipation plate 100 can be reduced, which is beneficial to the lightweighting of the vehicle 1.

[0070] like Figure 4 As shown, optionally, the perforated hole 121 is positioned opposite to the heat dissipation fins of the power amplifier 30.

[0071] like Figure 5 As shown, in some embodiments, the first plate 110 is inclined, and the second side 112 is bent and connected to one side of the second plate 120, so that the second plate 120 is suspended above the first side 111. This facilitates the formation of a heat dissipation space 101. Furthermore, the protective heat dissipation plate 100 is easily formed by stamping sheet metal to create the first plate 110 and the second plate 120.

[0072] like Figure 6 As shown, the width direction of the protective heat sink 100 is the Y-axis direction. In some embodiments, the first connecting portion 113 includes at least two parts, which are spaced apart along the width direction of the protective heat sink 100. In this way, by providing at least two first connecting portions 113, the connection strength between the protective heat sink 100 and the front floor 22 can be increased, making the connection between the two reliable.

[0073] And / or, in some embodiments, the second connecting portion 131 includes at least two and is spaced apart along the width direction of the protective heat sink 100. In this way, by providing at least two second connecting portions 131, the connection strength between the protective heat sink 100 and the front panel 23 can be increased, making the connection between the two reliable.

[0074] like Figure 6 as well as Figure 7 As shown, in some embodiments, the first plate 110 includes a protective body 114 recessed in the direction away from the front floor 22 to form a relief cavity 102, a first support body 115 fixedly connected to one side wall of the protective body 114, and a second support body 116 fixedly connected to the other side of the protective body 114. The relief cavity 102 communicates with the heat dissipation space 101, and the first support body 115 and the second support body 116 are spaced apart along the width direction of the protective heat dissipation plate 100. At least one first connecting portion 113 is provided on the first support body 115, and at least one first connecting portion 113 is provided on the second support body 116. Thus, by setting the protective body 114 to form the relief cavity 102, the power amplifier 30 can be avoided, and a reinforcing rib can be formed to improve the strength of the first plate 110, so as to better protect the power amplifier 30. In addition, the first support body 115 and the second support body 116 are arranged on both sides of the protective body 114 to facilitate the contact between the front floor 22 and the first support body 115 and the second support body 116, thereby increasing the connection surface and thus improving the connection strength between the two.

[0075] Furthermore, when the first plate 110 is integrally formed to obtain the protective body 114, the first support body 115, and the second support body 116, it is easy to form support feet on both sides of the protective body 114 that connect with the front floor 22, so that the protective body 114 can be suspended above the front floor 22 to form a heat dissipation space 101 that communicates with the clearance cavity 102.

[0076] Optionally, such as Figure 7 As shown, in some embodiments, the protective body 114 is further provided with a first clearance groove 103 recessed in the direction away from the front floor 22. The first clearance groove 103 communicates with the clearance cavity 102 and is used to avoid the first wire harness 40. In this way, by providing the first clearance groove 103, the protruding structure on the first wire harness 40 can be avoided, and the protruding structure can be limited and matched with the first clearance groove 103 to better limit the shaking of the first wire harness 40.

[0077] Furthermore, such as Figure 7 as well as Figure 8 As shown, in some embodiments, the first side portion 111 is provided with a limiting body 117, which is spaced apart from the first support body 115 and forms a limiting notch 104 for fixing the first wiring harness 40. The limiting notch 104 and the first clearance groove 103 are connected. Thus, after the first wiring harness 40 is connected to the power amplifier 30, it extends to the outside of the heat dissipation space 101 through the limiting notch 104. The limiting body 117 cooperates with the front floor 22 to restrict the movement space of the first wiring harness 40.

[0078] Optionally, in some embodiments, the mounting base of the front floor 22 is provided with a snap-fit ​​portion for fixed connection with the first wiring harness 40. This facilitates the assembly and disassembly of the first wiring harness 40 from the front floor assembly 20.

[0079] like Figure 9 As shown, in some embodiments, the third plate 130 is bent and connected to the other end of the second plate 120, so that the third plate 130 is inclined. This makes it easier to orient the third plate 130 away from the first plate 110, facilitating its fixed connection with the front bulkhead 23. Furthermore, the protective heat dissipation plate 100 is easily formed by stamping sheet metal into the second plate 120 and the third plate 130.

[0080] like Figure 6 as well as Figure 9 As shown, in some embodiments, the third plate 130 includes a third connecting portion 132 for fixing the seat controller 50. This facilitates fixing the seat controller 50 to the third plate 130 via the third connecting portion 132, making full use of the space in the protective heat sink 100 for mounting the seat controller 50.

[0081] like Figure 6 As shown, in some embodiments, the third plate 130 further includes a bearing surface 133 for supporting the seat controller 50, and the bearing surface 133 is disposed close to the second plate 120. In this way, the second plate 120 can be used to abut against the seat controller 50, and the bearing surface 133 can be used to fit against the seat controller 50 to increase the connection area between the third plate 130 and the seat controller 50, thereby improving the connection strength of the fixed connection between the two.

[0082] Optionally, such as Figure 6 As shown, in some embodiments, the third connecting portion 132 includes at least two portions, which are spaced apart on both sides of the bearing surface 133. In this way, by providing at least two third connecting portions 132, the connection strength between the seat controller 50 and the third plate 130 can be increased, making the connection between the two reliable.

[0083] like Figure 6 , Figure 7 as well as Figure 10 As shown, in some embodiments, the third plate 130 further includes a clearance recess 134 spaced apart from the bearing surface 133 along the length of the protective assembly 21. The clearance recess 134 is recessed toward the front bulkhead 23, and at least a portion of the second connecting portion 131 is disposed within the clearance recess 134. Thus, by providing the clearance recess 134, the seat controller 50 and / or other structures can be avoided.

[0084] Furthermore, it is understood that at least a portion of the second connecting portion 131 is disposed within the clearance recess 134. In this case, the clearance recess 134 can be used as a support foot facing the front bulkhead 23. When the second connecting portion 131 is fixedly connected to the front bulkhead 23, the other parts of the third plate 130 can be suspended on the front bulkhead 23, and the second plate 120 and the first plate 110 are disposed away from the front bulkhead 23, which facilitates the increase of the heat dissipation space 101.

[0085] like Figures 2 to 6 as well as Figure 10 as well as Figure 11 As shown, in some embodiments, the protective assembly 21 further includes a protective cover 200 fixedly connected to the third plate 130 to form a protective cavity 201, the protective cavity 201 being used to protect the seat controller 50. Thus, fixing the protective cover 200 to the third plate 130 facilitates the use of the protective cavity 201 to protect the seat controller 50, improving the protective performance of the seat controller 50 and enhancing the durability of the vehicle 1 during operation.

[0086] like Figure 9 as well as Figure 10 As shown, in some embodiments, the third plate 130 is provided with a fourth connecting portion 135 fixedly connected to the protective cover 200, and the protective cover 200 is provided with a fifth connecting portion 210 fixedly connected to the fourth connecting portion 135. Thus, by fixing the fourth connecting portion 135 and the fifth connecting portion 210 together, it is easy to fix the protective cover 200 to the protective heat dissipation plate 100 and place it close to the front bulkhead 23. This facilitates full utilization of the bending space between the front floor 22 and the front bulkhead 23 to install the seat controller 50, improving the space utilization rate of the vehicle 1.

[0087] Optionally, in some embodiments, the second connecting portion is disposed within the protective cavity 201.

[0088] like Figure 9 as well as Figure 11As shown, in some embodiments, the protective cover 200 includes a clearance sidewall 220 spaced apart from the protective heat sink 100 and forming a clearance notch 202 for avoiding the second wiring harness 60, and a connecting sidewall 230 connected to the protective heat sink 100. The electrical connector 61 of the second wiring harness 60 is disposed within the protective cavity 201 and electrically connected to the seat controller 50. The connecting sidewall 230 is sealed to the protective heat sink 100 and / or the seat controller 50. Thus, after the second wiring harness 60 is connected to the seat controller 50, other portions of the second wiring harness 60 can extend to the outside of the protective cavity 201 through the clearance notch 202. Simultaneously, the sealing cooperation between the connecting sidewall 230 and the protective heat sink 100 and / or the seat controller 50 improves the waterproof performance of the protective cavity 201 and enhances the waterproof performance of the seat controller 50.

[0089] It should be noted that the term "sealing fit" should be interpreted broadly, including both circuitous waterproof structures and interlocking waterproofing, etc.

[0090] In some embodiments, a waterproof sealing layer is provided between the connecting sidewall 230 and the protective heat dissipation plate 100. Thus, the waterproof sealing layer further improves the waterproof performance of the protective cavity 201.

[0091] In some embodiments, the second plate 120 is provided with a sixth connecting portion 122 that is fixedly connected to the second wiring harness 60. Thus, after the first wiring harness 40 is connected to the power amplifier 30, it extends to the outside of the heat dissipation space 101 through the limiting notch 104. The movement space of the first wiring harness 40 is restricted by the limiting body 117 cooperating with the front floor 22.

[0092] like Figure 10 as well as Figure 11 As shown, in some embodiments, the outer wall of the protective cover 200 is provided with a guide channel 203. This allows liquids that easily flow into the front floor assembly 20 to be directed to other parts via the guide channel 203. Furthermore, the guide channel 203 also acts as a reinforcing rib, improving the strength of the protective cover 200 to better support structures such as the carpet 70.

[0093] Optionally, such as Figure 2 As shown, in some embodiments, the protective cover 200 cooperates with the first plate 110 and the second plate 120 to form a support structure for supporting the carpet 70. The vehicle 1 also includes the carpet 70. At least a portion of the carpet 70 covers the support structure. Thus, by using the protective heat dissipation plate 100 and the protective cover 200 to form a support structure to support the carpet 70, the carpet 70 is prevented from compressing the power amplifier 30 and the seat controller 50, thereby improving the durability of the vehicle 1.

[0094] Optionally, in some embodiments, the vehicle body 10 includes a passenger-side area, and the protective component 21 is disposed in the passenger-side area. This allows the power amplifier 30 and the seat controller 50 to be placed in the passenger-side area, reducing the occupancy of the interior passenger space of the vehicle body 10 and thus improving passenger space.

[0095] Understandably, compared to traditional technologies, the protection and arrangement scheme of the power amplifier 30 in this utility model does not reduce the effective space under the seat, thus avoiding inconvenience for rear passengers to stretch their legs forward and resulting in a poor riding experience. There is no need to create ventilation holes on the carpet 70, and the wiring harness will not be worn. Furthermore, it will not encroach on the storage space in the trunk, reducing the product's competitiveness. The length of the wiring harness from the power amplifier 30 to the entertainment host is also shortened.

[0096] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0097] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0098] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0099] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0100] It should be noted that when a component is described as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable, such as through socketing, snap-fitting, integral molding, welding, etc., which are achievable in conventional technologies and will not be elaborated upon here.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
