Description

Technical Field

[0001] The utility model relates to the technical field of automobile switch accessories, in particular to an automobile power distribution switch. Background Art

[0002] With the development of the automotive industry and technological advancements, energy conservation and environmental protection have become key development priorities for the global automotive industry. Traditional vehicle power distribution systems are unable to flexibly adjust engine power output to varying driving conditions, resulting in energy waste under light loads and potential power shortages under heavy loads. Therefore, how to properly manage engine power output while ensuring normal vehicle operation has become a pressing issue.

[0003] Most vehicles currently on the market utilize a relatively fixed power distribution system, meaning that engine power output remains relatively constant regardless of vehicle load. While this approach is simple and reliable, it has certain limitations in practical application. For example, when driving on urban roads or when the vehicle is lightly loaded, operating the engine at a high power output can result in poor fuel efficiency and increased exhaust emissions. Furthermore, when the vehicle must overcome significant resistance, such as when climbing a hill or fully loaded, the fixed power output may not be sufficient to provide the necessary power, compromising vehicle stability and safety.

[0004] Therefore, developing a power distribution switch system that can dynamically adjust engine power output based on the vehicle's actual load, thereby achieving energy conservation and emission reduction, and improving driving safety and comfort, has important practical significance and technical value. This application aims to provide an automotive power distribution switch device that allows users to flexibly adjust power output according to different driving conditions, thereby addressing the shortcomings of the existing technology.

The second contact end contacts different short arc sheets, adjusting the engine power to varying degrees. Specifically, the three short arc sheets connect to circuits with different resistance values. Therefore, when the second contact end contacts different short arc sheets, the current flowing through the circuit changes. This intelligent power distribution switch adjusts the engine power output by controlling the resistance changes in the circuit. When the vehicle is lightly loaded, such as when traveling on city roads or with a light load, the driver can select a higher resistance setting, which reduces the current in the circuit and allows the engine to operate at a lower power curve. Similarly, when the vehicle is heavily loaded or climbing a hill, the driver can select a lower resistance setting to increase the current in the circuit, thereby enabling the engine to provide higher power output and ensure vehicle power support.

[0027] The following is a combination of the appended examples of the present invention Figure 1-9 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example:

[0029] like Figures 1 to 9As shown, the utility model discloses an automotive power distribution switch, including a housing 1, a roller 2 and a circuit board assembly 4. A mounting cavity 11 is provided in the housing 1, wherein the circuit board assembly 4 is fixedly mounted at a position on the rear side of the mounting cavity 11, and a bottom cover connector 5 is detachably covered at the lower end of the housing 1. A plug terminal 41 is electrically connected to the circuit board assembly 4 and penetrates downwardly through the bottom cover connector 5. The plug terminal 41 is used to connect to the vehicle's electrical system, particularly the engine control unit (ECU). The roller 2 is located in the mounting cavity 11, and the upper side of the roller 2 penetrates the mounting cavity 11 for rotation by the user. 2 is fixedly connected to the front side of the roller 2 with a front shaft 21 that rotatably engages with the housing 1. The roller 2 is provided with an assembly opening 22 on the side facing the circuit board assembly 4. A fixing seat 23 is integrally formed on the inner side wall of the assembly opening 22. The fixing seat 23 is fixedly connected to the conductive sheet 3. The conductive sheet 3 is provided with a first contact end 31 and a second contact end 32 for affixing to the circuit board assembly 4. In addition, the circuit board assembly 4 includes a long arc piece 42 for contacting the first contact end 31 and a short arc piece 43 for contacting the second contact end 32. Three short arc pieces 43 are provided and are distributed in an arc shape on the circuit board assembly 4.

[0030] When the roller 2 is rotated by the user, the roller 2 will drive the first contact end 31 and the second contact end 32 on the conductive sheet 3 to rotate synchronously. The second contact end 32 will switch on the three short arc sheets 43 during the rotation. During this process, the first contact end 31 will always be on the long arc sheet 42, and the second contact end 32 will contact different short arc sheets 43 to achieve different power adjustments of the engine. Specifically, the resistance values of the circuits connected to the three short arc sheets 43 in the circuit board assembly 4 are different, thereby forming three different gears. The three gears are respectively set to 10Ω, 20Ω, and 30Ω (according to the definition of the vehicle by the OEM). Since circuits with different resistance values of different short arc sheets 43 are very common in circuit boards, and are supported by a large number of mature technologies, the essence of the present invention is to optimize and combine existing hardware and their connection methods for specific applications, and does not involve improvements to the internal circuits. Therefore, the internal circuits of the circuit board assembly will not be described in detail here. Because the three short arc pieces 43 connect to circuits with different resistance values, when the second contact end 32 contacts different short arc pieces 43, the current intensity passing through the circuit changes. This intelligent power distribution switch adjusts the engine's power output by controlling the resistance change in the circuit. When the vehicle is lightly loaded, such as when traveling on city roads or carrying a light load, the driver can select a higher resistance setting (e.g., 30Ω), which will reduce the current in the circuit and thus allow the engine to operate at a lower power curve. Similarly, when the vehicle is facing high loads, such as when heavily loaded or climbing a slope, the driver can select a lower resistance setting (e.g., 10Ω) to increase the current in the circuit, thereby enabling the engine to provide higher power output and ensure vehicle power support.

[0031] like Figure 6 and Figure 9 As shown, the specific structure of the long arc piece 42 and the short arc piece 43 is set as follows: the long arc piece 42 is located on the inner side of the short arc piece 43, and the long arc piece 42 is located on the rotation trajectory when the first contact end 31 rotates around the front rotation axis 21, and the three short arc pieces 43 are also distributed in sequence on the rotation trajectory when the second contact end 32 rotates around the front rotation axis 21.

[0032] like Figure 7 and Figure 9As shown, a limit seat 6 located in the assembly opening 22 is fixedly connected to the front side of the circuit board assembly 4, and a supporting block 24 is integrally formed in the assembly opening 22 of the roller 2, and a first limiting step 61 and a second limiting step 62 are provided on the limiting seat 6. The first limiting step 61 and the second limiting step 62 are located on both sides of the rotation trajectory when the supporting block 24 rotates around the front rotating shaft 21. When the roller 2 is rotated, it will drive the supporting block 24 together, and the supporting block 24 can only rotate between the first limiting step 61 and the second limiting step 62. The setting of the supporting block 24 and the limiting seat 6 can limit the rotation range of the roller 2, and this range is that the second contact end 32 can only switch among the three short arc pieces 43, and the first contact end 31 can only rotate on the long arc piece 42, thereby preventing the first contact end 31 and the second contact end 32 from being rotated out of the range of the long arc piece 42 and the three short arc pieces 43.

[0033] like Figure 7 As shown, a positioning hole 63 is provided on the side wall of the limit seat 6, and a spring 71 is fixed to the inner end of the positioning hole 63, and a positioning ball head 72 is connected to the spring 71, and the roller 2 is provided with a positioning groove 25 for the positioning ball head 72 to abut on the inner wall of the assembly port 22, and there are three positioning grooves 25 in sequence. When the second contact end 32 contacts three different short arc pieces 43, the positioning ball head 72 is respectively located in the three different positioning grooves 25. This structure can facilitate the roller 2 to be positioned at the gear position where it contacts the second contact end 32 and different short arc pieces 43, thereby enhancing the interactive feedback between the product and the user.

[0034] like Figure 1 、 Figure 5 and Figure 6 As shown, a light guide column 8 is provided in the limit seat 6 of the utility model, and a light-transmitting port 64 for exposing the light guide column 8 is provided on the upper side of the limit seat 6, and a light inlet 65 leading to the light guide column 8 is provided on the side of the limit seat 6 facing the circuit board assembly 4, and an LED indicator 44 corresponding to the light inlet 65 is provided on the circuit board assembly 4. The LED indicator 44 injects light into the light inlet 65 through the light inlet 65, causing the light guide column 8 to glow and become brighter, and then the light guide column 8 disperses the light through the light-transmitting port 64, causing the roller 2 to become brighter. Furthermore, the roller 2 is made of a transparent material, and a light-shielding and anti-slip surface 26 is provided on the outer surface of the roller 2, and a light outlet 27 is provided on the light-shielding and anti-slip surface 26. There are three light outlets 27, and the light-transmitting port 64 corresponds to the three light outlets 27 when they are in contact with the second contact end 32 and three different short arc pieces 43 respectively. When the light outlet 27 and the light-transmitting port 64 on the roller 2 are aligned, the light outlet 27 will be fully illuminated, while other light outlets 27 that are not aligned with the light-transmitting port 64 will not emit light due to the setting of the light-shielding and anti-slip surface 26. This structure is conducive to clearly distinguishing the currently selected gear.

[0035] In order to improve the structural strength of the limit seat 6 and the circuit board assembly 4 installed in the shell 1, a connecting column 66 is provided on the rear side of the limit seat 6 to penetrate the circuit board assembly 4 and connect to the rear side of the shell 1. In addition, in order to improve the stability of the roller 2 rotating in the installation cavity 11, a support shaft 67 for rotating on the roller 2 is provided on the front side of the limit seat 6. The support shaft 67 is coaxial with the front shaft 21.

[0036] In the present invention, a detachable upper cover 9 is provided on the upper side of the housing 1 , and a through hole 91 is provided on the upper cover 9 for the upper side of the roller 2 to pass through.

[0037] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
