Description

Technical Field

[0001] The invention relates to the technical field of electric vehicle wiring, in particular to an electric vehicle wiring support device. Background Art

[0002] The electric vehicle industry is entering a period of rapid development. With the continuous innovation of technologies such as autonomous driving and smart cockpits, the degree of electrification and intelligence of electric vehicles continues to improve, and the wiring system of the whole vehicle is becoming more and more complex. According to statistics, the length of the wiring harness of a high-end electric vehicle can reach 3-5 kilometers, including hundreds of power cables and data cables of different specifications. These harnesses are not only responsible for the power transmission of core components such as power batteries and drive motors, but also for the signal interaction between the various electronic control units of the vehicle. At the same time, the design trend of electric vehicles pursuing lightweight and miniaturization makes the space inside the car more and more compact, which puts higher requirements on the spatial adaptability and integration of wiring support devices. In the field of new energy vehicles, electric vehicles have developed rapidly in recent years due to their advantages such as environmental protection and high efficiency. Electric vehicles rely on lead-acid batteries and sealed lithium battery boxes for power supply, and the position of power batteries is relatively fixed. Therefore, there are a large number of high-voltage or low-voltage connection harnesses in the car. Reasonable wiring and stable support of these harnesses are crucial to the safety and stability of the vehicle.

[0003] However, there are still some problems with the existing electric vehicle wiring support device when in use:

[0004] First, the existing wiring support device generally uses a simple elastic slot to fix the power cord. This fixing structure lacks adjustability and has a poor fixing effect. The power cord is easily separated from the slot during the support and fixing process, which reduces the wiring effect of the support device.

[0005] Secondly, the existing support device lacks a structure for assisting the positioning of the power cord. During the driving of the electric vehicle, the bumpy road surface will cause the power cord to shake. Due to the lack of effective auxiliary positioning, it is difficult to maintain a stable support by only relying on a single card slot, which will also reduce the use effect of the support device.

[0006] In addition, the position of the mounting plate on the existing support device relative to the support seat is generally fixed. When installing the support device, due to the compact interior space layout of the automobile and limited installation space, the mounting plate of this fixed structure cannot be flexibly adjusted according to the actual installation environment, which not only increases the difficulty of installation, but also greatly reduces the convenience of installation of the support device. Summary of the invention

[0007] In order to solve the problems that the fixed structure of the existing support device lacks adjustability and auxiliary positioning structure when in use and the position of the mounting plate cannot be flexibly adjusted according to actual conditions; the purpose of the present invention is to provide an electric vehicle wiring support device.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions: An electric vehicle wiring support device includes a support base. On one side of the support base, snap-in grooves are symmetrically and fixedly installed. This design not only facilitates the rapid assembly of the support device with more support devices. On both sides of the support base, mounting plates are slidably connected. A through groove is formed on one side of the support base, and an adjustment component for cooperating with the mounting plate is provided inside the through groove. The adjustment component facilitates flexibly adjusting the position of the mounting plate according to the actual installation space, so as to better install the wiring support device. An adjustable fixing component is provided inside the cavity of the support base. The adjustable fixing component can adjust and fix power cords with different diameter specifications, eliminating the need to replace the support device due to power cord specification differences, improving the versatility and practicality of the support device. An auxiliary positioning component is provided inside the adjustable fixing component. The auxiliary positioning component and the adjustable fixing component form a dual protection system. The dual protection system further enhances the fixing effect on the power cord. Based on the adjustable fixing component, the auxiliary positioning component provides additional positioning and clamping forces, ensuring that the power cord remains stable and does not shake even under external forces such as vibration and bump during the driving of the electric vehicle, reducing the risk of failures caused by the loosening of the power cord. The adjustable fixing component includes a guide plate fixedly installed on one side of the support base. A bushing is slidably connected to the outer surface of the guide plate. A locking bolt is commonly threaded between the bushing and the guide plate. The sliding fit between the guide plate and the bushing and the design of the locking bolt facilitate changing the position of the fixing plate by adjusting the position of the bushing on the guide plate, thereby adapting to power cords with different diameters. Equally spaced first screw holes are formed on the upper surface of the guide plate. A second screw hole is formed on the upper surface of the bushing. The locking bolt is threadedly connected to the corresponding first screw hole and second screw hole. The threaded connection between the first screw hole and the second screw hole provides an accurate installation position for the locking bolt. A fixing plate is fixedly installed on one side of the bushing, and the lower surface of the fixing plate is slidably connected to the cavity of the support base. A clamping block is fixedly connected to the lower part of one side of the fixing plate. A clamping groove for cooperating with the clamping block is formed on one side of the support base. The clamping block is slidably connected to the clamping groove. The cooperation between the clamping block and the clamping groove ensures the stability and precise positioning during the sliding of the fixing plate. First rubber anti-slip pads are fixedly connected to both sides of the fixing plate. Second rubber anti-slip pads are symmetrically and fixedly connected to the cavity of the support base. The first rubber anti-slip pads and the second rubber anti-slip pads increase the friction force with the power cord, preventing the power cord from sliding and further improving the fixing reliability.

[0009] Preferably, the auxiliary positioning component includes an installation groove which is opened inside the fixing plate. A first micro electric rod and a second micro electric rod are respectively and fixedly installed inside the installation groove. The output ends of the first micro electric rod and the second micro electric rod are respectively fixedly connected with a first positioning plate and a second positioning plate. The first micro electric rod and the second micro electric rod can accurately control the extension and retraction of the first positioning plate and the second positioning plate, and perform precise positioning and clamping according to the actual position and size of the power cord. Here, both the first positioning plate and the second positioning plate are anti-slip plates, realizing automatic and intelligent auxiliary fixation, enhancing the fixation effect and protection ability of the power cord, and further improving the support and fixation effect of the support device on the power cord.

[0010] Preferably, the adjusting component includes a base which is fixedly installed inside the through groove. A servo motor is fixedly installed on the upper surface of the base. The base provides a stable installation position for the servo motor to ensure the stability of the servo motor during operation. The output end of the servo motor is fixedly connected with a first bevel gear. The outer surface of the first bevel gear is meshed with a second bevel gear. The output end of the servo motor drives the second bevel gear to rotate by driving the first bevel gear to rotate. The inner wall of the second bevel gear is fixedly connected with a round rod. The second bevel gear rotates to drive the round rod to rotate, and the ends of the round rod are rotatably connected to the inner cavity of the through groove, which can effectively ensure the smooth rotation of the round rod. A bidirectional screw rod is fixedly sleeved on the outer surface of the round rod. The round rod drives the bidirectional screw rod to rotate synchronously. The outer surface of the bidirectional screw rod is threadedly sleeved with a moving rod. The moving rod is threadedly sleeved on the outer surface of the bidirectional screw rod with opposite thread directions, facilitating the movement of the moving rod in the same or opposite directions. The moving rod is slidably connected with the through groove to ensure the smooth movement of the moving block and prevent the bidirectional screw rod from driving the moving rod to rotate when it rotates. The inner walls of the through groove are symmetrically and fixedly connected with limit baffles for use with the moving rod. The limit baffles play a role in limiting the moving position of the moving rod to prevent the moving rod from disengaging from the bidirectional screw rod when it moves. The mounting plates are fixedly installed on both sides of the moving rod. The movement of the moving rod drives the mounting plates to move, accurately adjusting the position of the mounting plates, enabling the support device to adapt to complex and changeable installation environments, ensuring stable installation, and improving the installation efficiency and adaptability.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. Through the setting of the adjustable fixing component, the position of the fixing plate can be flexibly adjusted according to the actual diameter size of the power cord. Compared with the traditional fixing method of elastic card slots, this dynamic adjustment mechanism can achieve precise fitting and stable clamping of the power cord, effectively improving the wiring effect of its wiring support device;

[0013] 2. Through the setting of the auxiliary positioning component, the power cord is assisted and fixed from above, which can effectively resist the bumps and vibrations during vehicle driving, prevent the power cord from detaching from the card slot due to shaking, facilitate maintaining stable support, and significantly improve the use effect of the support device.

[0014] 3. Through the adjustment component, users can flexibly adjust the relative position of the mounting plate on the support base according to the complex and changeable installation space inside the vehicle, enabling the wiring support device to adapt to a variety of vehicle models and installation scenarios, reducing the installation difficulty, and significantly improving the installation convenience of the support device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example: Figures 1-6 As shown, the present invention provides an electric vehicle wiring support device, including a support seat 1, one side of the support seat 1 is symmetrically fixedly installed with a snap-fit groove 7, the snap-fit groove 7 is symmetrically arranged on one side of the support seat 1, and can be spliced with more support seats 1 to realize wiring of more power sources, both sides of the support seat 1 are slidably connected with mounting plates 5, one side of the support seat 1 is provided with a through groove 6, the interior of the through groove 6 is provided with an adjustment component 4 used in conjunction with the mounting plate 5, the mounting plate 5 is slidably connected to the support seat 1, and its movement in the through groove 6 is controlled by the adjustment component 4, the position of the mounting plate 5 can be flexibly adjusted according to the complex installation space inside the car, so that the wiring support device can adapt to different car models and installation environments, solves the problem that the traditional fixed mounting plate 5 is difficult to adapt to a small space, and significantly improves the convenience of installation.

[0025] The inner cavity of the support seat 1 is provided with an adjustable fixing component 2, and the adjustable fixing component 2 is arranged in the inner cavity of the support seat 1, providing an adjustable fixing method for the power cord. Compared with the traditional elastic fixation, the fixing force and position can be flexibly adjusted according to the diameter of the power cord, thereby realizing accurate fixation of power cords of different specifications, enhancing the fixing effect, and effectively preventing the power cord from detaching during the support process, thereby improving the stability and reliability of the wiring support device; the interior of the adjustable fixing component 2 is provided with an auxiliary positioning component 3, and the auxiliary positioning component 3 is built into the adjustable fixing component 2, and works with the adjustable fixing component 2 to perform secondary positioning and fixation of the power cord from above. When bumps occur during the driving of the electric vehicle, the auxiliary positioning component 3 can effectively limit the shaking of the power cord and prevent it from detaching from the fixed structure, further enhancing the support device's ability to firmly support the power cord and ensuring the safety of the wiring harness under complex working conditions.

[0026] The adjustable fixing component 2 includes a guide plate 24, which is fixedly installed on one side of the support base 1. A sleeve 25 is slidably connected to the outer surface of the guide plate 24. The guide plate 24 is fixed to one side of the support base 1 to provide sliding guidance for the sleeve 25, enabling the sleeve 25 to move smoothly along the guide plate 24. A locking bolt 21 is commonly threadedly connected between the sleeve 25 and the guide plate 24. A first screw hole 22 is equidistantly formed on the upper surface of the guide plate 24, and a second screw hole 23 is formed on the upper surface of the sleeve 25. The locking bolt 21 is threadedly connected to the corresponding first screw hole 22 and second screw hole 23. A fixing plate 27 is fixedly installed on one side of the sleeve 25. By adjusting the threaded connection position of the locking bolt 21 with the first screw hole 22 and the second screw hole 23, the sleeve 25 can be fixed at different positions on the guide plate 24, thereby adjusting the position of the fixing plate 27 to adapt to power cords of different diameters.

[0027] Moreover, the lower surface of the fixing plate 27 is slidably connected to the inner cavity of the support base 1. A clamping block 29 is fixedly connected to the lower part of one side of the fixing plate 27. A clamping groove 201 for cooperating with the clamping block 29 is formed on one side of the support base 1. The clamping block 29 is slidably connected to the clamping groove 201. The fixing plate 27 is slidably matched with the clamping groove 201 of the support base 1 through the clamping block 29, and can smoothly slide in the inner cavity of the support base 1 under the drive of the sleeve 25, further improving the stability and accuracy during the adjustment of the fixing plate 27. At the same time, the cooperation between the clamping block 29 and the clamping groove 201 also plays a certain limiting role on the fixing plate 27, preventing it from shaking or shifting during the process of fixing the power cord and ensuring the fixing effect. First rubber anti-slip pads 26 are fixedly connected to both sides of the fixing plate 27, and second rubber anti-slip pads 28 are symmetrically and fixedly connected to the inner cavity of the support base 1. The first rubber anti-slip pads 26 and the second rubber anti-slip pads 28 are respectively arranged on both sides of the fixing plate 27 and in the inner cavity of the support base 1, increasing the friction with the power cord. When the fixing plate 27 fixes the power cord, the rubber anti-slip pads can closely fit the surface of the power cord, preventing the power cord from sliding due to vehicle vibration. At the same time, the rubber material also has a certain buffering effect, which can avoid damaging the epidermis of the power cord, protecting the power cord while firmly fixing it.

[0028] The auxiliary positioning component 3 includes an installation groove 33 which is opened inside the fixing plate 27. The inner part of the installation groove 33 is fixedly installed with a first micro electric rod 32 and a second micro electric rod 31 respectively. The installation of the installation groove 33 inside the fixing plate 27 provides an installation space for components such as the first micro electric rod 32 and the second micro electric rod 31, enabling the auxiliary positioning component 3 to be compactly integrated inside the adjustable fixing component 2. The output ends of the first micro electric rod 32 and the second micro electric rod 31 are fixedly connected with a first positioning plate 34 and a second positioning plate 35 respectively. The first micro electric rod 32 and the second micro electric rod 31 drive the first positioning plate 34 and the second positioning plate 35 to extend or retract, which can dynamically clamp and position the power cord from above, forming an upper and lower double fixing structure. This design effectively prevents the power cord from being displaced due to shaking during the bumpy driving of the vehicle, significantly improving the stability and reliability of the support device.

[0029] The adjusting component 4 includes a base 46 which is fixedly installed inside the through groove 6. The upper surface of the base 46 is fixedly installed with a servo motor 45. The base 46 provides a stable installation position for the servo motor 45, and the output end of the servo motor 45 is fixedly connected with a first bevel gear 44, facilitating the output end of the servo motor 45 to drive the first bevel gear 44 to rotate. The outer surface of the first bevel gear 44 is meshed with a second bevel gear 48. The rotation of the first bevel gear 44 drives the rotation of the second bevel gear 48. The inner wall of the second bevel gear 48 is fixedly connected with a round rod 47. The rotation of the second bevel gear 48 drives the rotation of the round rod 47, and the ends of the round rod 47 are rotatably connected to the inner cavity of the through groove 6, ensuring the smooth rotation of the round rod 47.

[0030] The outer surface of the round rod 47 is fixedly sleeved with a bidirectional screw rod 43. The rotation of the round rod 47 drives the rotation of the bidirectional screw rod 43. The outer surface of the bidirectional screw rod 43 is threadedly sleeved with a moving rod 42. The moving rod 42 is threadedly sleeved on the opposite thread directions provided on the outer surface of the bidirectional screw rod 43. The moving rod 42 is slidably connected with the through groove 6. The inner wall of the through groove 6 is symmetrically and fixedly connected with limit baffles 41 for use with the moving rod 42. The moving rod 42 slides in the through groove 6, and the limit baffles 41 limit its moving range, preventing the moving rod 42 from disengaging from the bidirectional screw rod 43 during the adjustment process. The mounting plate 5 is fixedly installed on both sides of the moving rod 42. The bidirectional screw rod 43 rotates driven by the round rod 47. Since the moving rod 42 is threadedly sleeved on the opposite thread directions of the bidirectional screw rod 43, the two moving rods 42 can move in opposite directions or the same direction simultaneously when the bidirectional screw rod 43 rotates, thereby driving the mounting plates 5 on both sides to synchronously adjust their positions, so as to adapt to different installation environments inside the vehicle, greatly improving the convenience and flexibility of the installation of the wiring support device.

[0031] Working principle: First, when it is necessary to adjust the installation position of the support device according to the internal space of the vehicle, start the servo motor 45 in the adjustment component 4. The output end of the servo motor 45 drives the first bevel gear 44 to rotate. The first bevel gear 44 transmits power to the second bevel gear 48 through meshing transmission, and then drives the round rod 47 to rotate inside the through groove 6 cavity.

[0032] The round rod 47 drives the fixedly sleeved bidirectional screw 43 to rotate synchronously. Since the moving rods 42 are threadedly sleeved on the opposite thread directions of the bidirectional screw 43, the two moving rods 42 slide in opposite or the same directions along the guiding baffle 41 on the inner wall of the through groove 6 under the thread transmission.

[0033] The moving rods 42 drive the mounting plates 5 on both sides to move synchronously. The guiding baffle 41 limits the stroke of the moving rods 42 to prevent them from detaching from the bidirectional screw 43. After adjusting to the appropriate position, turn off the servo motor 45, and the mounting plates 5 cooperate with the mounting components to reasonably install the support device inside the vehicle.

[0034] Next, place the power cord to be fixed in the support base 1. According to the diameter of the power cord, loosen the locking bolt 21 in the adjustable fixing component 2. The ferrule 25 can slide up and down along the guiding plate 24, driving the fixing plate 27 to move synchronously. The clamping blocks 29 on the side of the fixing plate 27 slide along the card slot 201 of the support base 1 to ensure a stable and non-offset movement process.

[0035] After adjusting the ferrule 25 to the appropriate position, align the second screw hole 23 of the ferrule 25 with the first screw hole 22 at the corresponding position of the guiding plate 24, insert the locking bolt 21 and tighten it to fix the ferrule 25 and the guiding plate 24 through threaded connection, so that the fixing plate 27 is maintained at the target position.

[0036] At the same time, the first rubber anti-slip pads 26 on both sides of the fixing plate 27 and the second rubber anti-slip pads 28 in the inner cavity of the support base 1 form an upper and lower clamping structure. When the power cord is placed between the two, the rubber anti-slip pads closely fit the surface of the cable with high friction, buffer the vehicle vibration, and prevent the power cord from sliding and wearing.

[0037] After the power cord is pre-fixed, start the first micro electric rod 32 and the second micro electric rod 31 in the auxiliary positioning component 3. The output ends of the first micro electric rod 32 and the second micro electric rod 31 respectively push the first positioning plate 34 and the second positioning plate 35 to move, pressing the power cord from above.

[0038] By controlling the telescopic length of the electric rod, the pressure of the positioning plate on the power cord can be adjusted to adapt to different thickness cables, effectively resisting the loosening or detachment of the wire harness caused by vehicle bumps.

[0039] Moreover, the snap-in groove 7 on one side of the support base 1 can be quickly snap-fitted with the snap structures of other components, facilitating the splicing of more wiring support devices on one side of the support base 1.

[0040] Through the linkage of the adjustment assembly 4, the adjustable fixing assembly 2, and the auxiliary positioning assembly 3, the device can not only flexibly adjust the fixing method according to the power cord specifications but also adapt to the complex vehicle interior space, solving the problems of unstable fixing and inconvenient installation of traditional support devices.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
