Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a multi-anchor point fixing device, a multi-anchor point adjustment system, and a vehicle. Background Technology

[0002] The vehicle trunk, as a crucial storage space, is the core area for users to load luggage and other items when traveling. Currently, to secure items in the trunk, users typically purchase trunk securing nets, straps, or other restraint accessories. However, these accessories are relatively simple, only providing basic item securing. They cannot flexibly adjust the securing points according to the size of the luggage or support extended usage scenarios such as hanging banners, thus failing to meet the diverse needs of users. Summary of the Invention

[0003] This application provides a multi-anchor point fixing device, a multi-anchor point adjustment system, and a vehicle to solve the technical problem that the existing restraint accessories have limited functions and cannot meet the diverse needs of users.

[0004] In a first aspect, this application provides a multi-anchor point fixing device for a vehicle trunk, comprising: A winding assembly, located within the trunk, includes a drive unit, a winding reel, a rope, and a sensor. The winding reel is connected to the drive end of the drive unit. The rope is wound around the winding reel, and the winding reel can release or retract the rope under the drive of the drive unit. The force sensor is used to monitor the tension of the rope in real time. Anchor points are provided in the trunk, and there are multiple anchor points, which are used to connect to the rope.

[0005] In an optional embodiment, the winding assembly further includes a pretensioner coaxially disposed with the winding reel for applying a pretension force to the rope as the winding reel releases or retracts the rope.

[0006] In an alternative embodiment, the winding assembly further includes a guide wheel disposed on one side of the winding wheel, and the rope passes around the guide wheel.

[0007] In an optional embodiment, the take-up assembly further includes a speed reduction mechanism disposed between the drive member and the take-up reel; and / or A locking mechanism, wherein the locking structure is coaxially arranged with the winding reel, is used to lock the rope when the winding reel stops rotating.

[0008] In one alternative embodiment, the anchor point includes a fixing part and a hanging ring, the fixing part being installed inside the trunk, and the hanging ring being disposed on the fixing part for connection of the rope.

[0009] In an alternative embodiment, the free end of the rope is provided with a fixing hook that can be hooked onto the hanging ring.

[0010] Secondly, this application provides a multi-anchor point adjustment system, including: The aforementioned multi-anchor point fixing device; The control unit is electrically connected to the drive unit and the force sensor respectively. The control unit can receive the signal from the force sensor in real time. When the tension of the rope is greater than a preset tension threshold, the control unit controls the drive unit to drive the winding wheel to release the rope. When the tension of the rope is less than the preset tension threshold, the control unit controls the drive unit to drive the winding wheel to retract the rope.

[0011] In one optional implementation, the preset tension threshold is greater than or equal to 10N and less than or equal to 60N.

[0012] In one alternative implementation, the multi-anchor point adjustment system further includes an acceleration sensor capable of monitoring the vehicle's acceleration in real time; The acceleration sensor is electrically connected to the control unit. The control unit can receive the signal from the acceleration sensor in real time. When the acceleration is greater than a preset acceleration threshold, the control unit controls the drive component to drive the winding wheel to retract the rope.

[0013] Thirdly, this application provides a vehicle including the aforementioned multi-anchor point adjustment system.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art: The anchor point fixing device provided in this application installs a retractable assembly and multiple anchor points on the inner wall of the trunk. When needed, the user releases the rope and freely selects the connecting anchor points and rope winding method according to usage requirements. By setting multiple anchor points in the trunk and cooperating with the retractable assembly, the rope can be flexibly matched with different anchor points to complete various cable routing arrangements, resulting in diverse forms. Users can arbitrarily change the arrangement method according to actual usage needs, taking into account various usage requirements such as hanging items, displaying goods, and restraining luggage. This effectively solves the technical problem that existing trunk restraint accessories have limited functionality and cannot meet the diverse usage needs of users. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0023] To address the technical problem that existing restraint accessories have limited functionality and cannot meet the diverse needs of users, this application provides a multi-anchor point fixing device, a multi-anchor point adjustment system, and a vehicle, which can effectively solve the technical problem that existing trunk restraint accessories have limited functionality and cannot meet the diverse needs of users.

[0024] In a first aspect, embodiments of this application provide a multi-anchor point fixing device for a vehicle trunk 1, comprising: A winding assembly 100 is disposed in the trunk 1. The winding assembly 100 includes a drive unit 120, a winding reel 130, a rope 140, and a force sensor 150. The winding reel 130 is connected to the drive end of the drive unit 120. The rope 140 is wound around the winding reel 130. The winding reel 130 can release or retract the rope 140 under the drive of the drive unit 120. The force sensor 150 is used to monitor the tension of the rope 140 in real time. Anchor points 200 are provided in the trunk 1 and there are multiple anchor points 200 for connecting to ropes 140.

[0025] like Figures 1 to 6 As shown, the retractable assembly 100 is installed on the inner wall of the trunk 1. The specific installation location can be flexibly selected according to user needs and vehicle model factors. The assembly method can be a fixed connection such as bolts, or a detachable connection such as clips or tenon joints. Due to the large volume and weight of the items stored in the trunk 1, a fixed connection is preferred. A fixed connection effectively improves the installation firmness of the retractable assembly 100, making it less likely to detach under tension.

[0026] The take-up assembly 100 includes a housing 110, a drive unit 120, a take-up reel 130, a rope 140, and a sensor. The drive unit 120, take-up reel 130, rope 140, and sensor are all integrated inside the housing 110, which has a rope outlet. The drive unit 120 can be a servo motor. The take-up reel 130 is connected to the output shaft of the servo motor, and the servo motor drives the take-up reel 130 to rotate. The rope 140 is wound around the take-up reel 130, with one end being the beginning end and fixedly connected to the take-up reel 130, and the other end being the end end and free end. When the take-up reel 130 rotates forward, the rope 140 is released; when the take-up reel 130 rotates in the reverse direction, the rope 140 is retracted.

[0027] The force sensor 150 can monitor the tension signal of the rope 140 in real time and feed the obtained tension signal back to the control unit. The control unit can control the action of the drive component 120 in real time according to the collected tension signal of the rope 140, thereby controlling the forward and reverse rotation of the winding wheel 130 to realize the release and retraction of the rope 140.

[0028] Specifically, the control unit can be integrated into the vehicle domain controller (i.e., an integrated domain control solution). The winding assembly 100 has a reserved power interface and a dedicated communication terminal interface, which connects to the drive unit 120, the force sensor 150, and the vehicle domain controller. The vehicle domain controller can receive the tension signal output by the force sensor in real time, process it to obtain the real-time tension data of the rope 140, output the corresponding drive signal based on the tension data, and transmit it to the servo motor through the dedicated communication terminal interface to drive the servo motor to move.

[0029] Alternatively, the control unit can be integrated into the housing 110 (i.e., the winding assembly is controlled independently). The winding assembly 100 also has a reserved power interface and a dedicated communication terminal interface. The control unit is directly electrically connected to the drive unit 120 and the force sensor 150. The dedicated communication terminal interface is connected to the vehicle domain controller via a CAN (Controller Area Network) bus. The control unit receives vehicle-related signals from the vehicle domain controller through the dedicated communication terminal interface. The control unit also synchronously receives the tension signal output by the force sensor 150 in real time, processes it to obtain the real-time tension data of the rope 140, and outputs the corresponding drive signal according to the tension data. The drive signal is directly sent to the servo motor to drive the servo motor to move.

[0030] Furthermore, when the control unit is integrated into the vehicle's domain controller, the domain controller is also electrically connected to the in-vehicle operation display screen. When the control unit is located within the housing 110, it is also electrically connected to the in-vehicle operation display screen via a CAN (Controller Area Network) bus. Thus, the tension data of the rope 140 can be displayed in real time on the in-vehicle operation display screen, allowing the user to observe and adjust the tension of the rope 140. In addition, a mechanical operation button electrically connected to the domain controller can be provided, allowing the user to adjust the tension of the rope 140.

[0031] The trunk 1 is also equipped with multiple anchor points 200, the specific locations of which can be flexibly selected according to user needs and vehicle models. Anchor points 200 have connecting parts for ropes 140 to connect to. Anchor points 200 are located on the inner sidewall of the trunk 1, and the assembly method can be a fixed connection such as bolts, or a detachable connection such as clips or tenon joints. The specific assembly method can be selected according to user needs and the vehicle model to which the anchor point 200 fixing device is to be installed.

[0032] In the embodiments disclosed in this application, five anchor points 200 are provided, two of which are spaced apart along the length of the vehicle body on the left inner wall of the trunk 1, and the other three are spaced apart in a triangular shape on the right inner wall of the trunk 1. The retractable assembly 100 is provided on the left inner wall of the trunk 1, and the rope 140 can be selectively connected to any anchor point 200.

[0033] like Figure 1 In the embodiment shown, after the free end of the rope 140 extends out, it is connected to an anchor point 200 located at a higher position on the inner wall of the right side of the trunk 1. At this time, the rope 140 spans the width of the vehicle trunk 1 and can be used to hang clothes or banners, such as birthday greeting banners.

[0034] like Figure 2 In the embodiment shown, after the free end of the rope 140 extends, it first connects to an anchor point 200 located at a relatively high position on the inner wall of the right side of the trunk 1. Then it is pulled back to the left side of the trunk 1 and connected to an anchor point 200 located at a relatively close position on the inner wall of the left side of the trunk 1. Then it is pulled back to the right side of the trunk 1 and connected to an anchor point 200 located at a relatively close position on the inner wall of the right side of the trunk 1. Finally, a Z-shaped rope 140 is formed, which can be used to place items.

[0035] like Figure 3 In the embodiment shown, a suitcase is placed in the trunk 1. After the free end of the rope 140 extends out, it first connects to an anchor point 200 located on the left inner wall of the trunk 1, which is positioned relatively close to the front of the vehicle. After passing around the suitcase, it connects to an anchor point 200 located on the right inner wall of the trunk 1, which is positioned relatively close to the front of the vehicle. In this way, the trunk 1 can be stably fixed in the trunk 1.

[0036] It should be noted that the connection method between the rope 140 and the anchor point 200 is not limited to the three mentioned above. Users can freely choose the connection method of the anchor point 200 and the rope 140 according to their needs.

[0037] When the user winds the connecting rope 140, the force sensor 150 monitors the tension of the rope 140 in real time. The user can adjust the tension of the rope 140 according to the usage requirements to ensure the stability of the fixed items in the trunk 1.

[0038] This application sets multiple anchor points 200 in the trunk 1, and with the retraction component 100 and rope 140, different anchor points 200 can be flexibly selected to complete various wiring arrangements. The arrangements are diverse and users can change them at will according to actual usage needs, taking into account various usage needs such as hanging items, displaying goods, and restraining luggage. This effectively solves the technical problem that the existing trunk 1 restraint accessories have a single function and cannot meet the diverse usage needs of users.

[0039] Furthermore, this application employs a force sensor 150 to monitor the tension of the rope 140 in real time, which can automatically or manually adjust the tension of the rope 140. Compared with existing restraint devices that rely on their own elasticity for limiting, this application can maintain the effective tension of the rope 140 in real time, effectively suppressing the shaking and displacement of items in the trunk 1 during vehicle operation, and effectively improving the storage stability and driving safety of the vehicle.

[0040] In some embodiments, the winding assembly 100 further includes a pretensioner 160, which is coaxially disposed with the winding reel 130 and is used to apply a pretension force to the rope 140 when the winding reel 130 releases or retracts the rope 140.

[0041] like Figure 4 As shown, the winding assembly 100 also includes a pretensioner 160, which is coaxially arranged with the winding reel 130 and can be integrated into the housing 110 without occupying additional space in the trunk 1. It should be noted that the pretensioner 160 is a conventional and mature component in the prior art, and there are many common types such as electric drive type and spring type, which will not be described in detail here.

[0042] In this application, the pretensioner 160 and the winding reel 130 are coaxially arranged. The pretensioner 160 can continuously apply basic pretension force to the rope 140 throughout the entire process of the winding reel 130 releasing and retracting the rope 140, so as to avoid problems such as natural slack of the rope 140 after free connection and winding.

[0043] In some embodiments, the take-up assembly 100 further includes a guide wheel 170 disposed on one side of the take-up wheel 130, and the rope 140 passes around the guide wheel 170.

[0044] like Figure 4 The winding assembly 100 further includes a guide wheel 170, which is rotatably mounted inside the housing 110 and located on one side of the winding reel 130. The mounting shaft of the guide wheel 170 is parallel to the output shaft of the drive unit 120, so that the guide wheel 170 and the winding reel 130 are parallel. The rope 140 is led out from the winding reel 130, passes around the guide wheel 170, and then extends outward. The guide wheel 170 can passively rotate as the rope 140 is wound and unwound, providing limiting guidance for the rope 140 throughout the entire process of its release and retraction.

[0045] The guide wheel 170 is arranged parallel and coaxially with the take-up wheel 130, which can regulate the direction of the rope 140's exit, prevent the rope 140 from deviating or tilting during take-up and take-down, and prevent the rope 140 from rubbing against the edge of the housing 110 and causing wear. Through the guidance and limiting of the guide wheel 170, the rope 140 is taken up and down more smoothly, which can reduce the operating load of the drive component 120 and extend the service life of the rope 140.

[0046] In some embodiments, the take-up assembly 100 further includes a reduction mechanism 180 disposed between the drive member 120 and the take-up reel 130; and / or The locking mechanism 190, with its locking structure coaxially arranged with the winding reel 130, is used to lock the rope 140 when the winding reel 130 stops rotating.

[0047] like Figure 4As shown in the embodiments disclosed in this application, the winding assembly 100 further includes a reduction mechanism 180, which is arranged between the drive member 120 and the winding reel 130 and is disposed within the housing 110. The reduction mechanism 180 can reduce the output speed, increase the output torque, and improve the load-bearing capacity of the drive member 120 driving the winding reel 130 to wind and unwind the rope 140. It should be noted that the reduction mechanism 180 is a conventional and mature component in the prior art, and there are many common types such as planetary gear reduction mechanism 180 and worm gear reduction mechanism 180, which will not be described in detail here.

[0048] The winding assembly 100 also includes a locking mechanism 190, which is coaxially arranged with the winding reel 130 and housed within the housing 110. The locking mechanism 190 rotates synchronously with the winding reel 130 and can lock and limit the winding reel 130 after it stops rotating, thereby locking the rope 140 and restricting its free extension and retraction. It should be noted that the locking mechanism 190 is a conventional and mature component in the prior art, commonly including ratchet and pawl locking mechanisms, electromagnetic brake locking mechanisms, and other types, which will not be elaborated upon here.

[0049] In some embodiments, the anchor point 200 includes a fixing part 210 and a hanging ring 220. The fixing part 210 is used to install in the trunk 1, and the hanging ring 220 is disposed on the fixing part 210 for the rope 140 to be connected.

[0050] like Figure 5 As shown in the embodiments disclosed in this application, the anchor point 200 includes a fixing part 210 and a hanging ring 220. The anchor point 200 can be installed in the trunk 1 as a whole through the fixing part 210. As mentioned above, the fixing part 210 can be a fixed assembly or a detachable assembly. The assembly form is flexible and can be adapted to different vehicle models and meet different usage needs.

[0051] The hanging ring 220 is fixedly installed on the outside of the fixing part 210 and serves as a connection structure for the anchor point 200 and the rope 140. Specifically, the hanging ring 220 can adopt a D-shaped ring structure, which is highly versatile and adaptable to various types of rope 140 winding. An opening is provided on one side of the hanging ring 220, allowing the rope 140 to be directly and quickly inserted into the hanging ring 220 and wound around it, effectively simplifying the connection process between the rope 140 and the anchor point 200.

[0052] Furthermore, a movable wrench can be hinged to the opening of the hanging ring 220. This movable wrench can rotate relative to the hanging ring 220 body to open and close. When the user needs to attach or detach the rope 140, they can manually operate the movable wrench to open the opening of the hanging ring 220, allowing the rope 140 to quickly engage or disengage from the hanging ring 220. After assembling the rope 140, the movable wrench can be released to return to its original position and close, sealing the opening of the hanging ring 220 and preventing the rope 140 from coming loose during use. Of course, the hanging ring 220 can be omitted, and other connection structures can be used, such as a slot structure, to insert the rope 140 into the slot and limit and fix the rope 140 through the slot.

[0053] In some embodiments, the free end of the rope 140 is provided with a fixing hook 141, which can be hooked onto the hanging ring 220.

[0054] like Figure 5 As shown in the embodiments disclosed in this application, a fixing hook 141 is provided at the free end of the rope 140. The fixing hook 141 is securely connected to the free end of the rope 140 as an integral structure. The fixing hook 141 can adopt a common hook structure. The fixing hook 141 can be matched with each anchor point 200 in the trunk 1 and can be directly hooked and fixed to the hanging ring 220, realizing a quick connection between the free end of the rope 140 and the anchor point 200.

[0055] By integrating a fixing hook 141 at the free end of the rope 140, the rope 140 can be quickly connected to the anchor point 200. Compared with the method of directly wrapping and binding the rope 140, the connection between the fixing hook 141 and the hanging ring 220 is simpler and more efficient, which can effectively reduce the difficulty for users to lay and adjust the rope 140.

[0056] Secondly, embodiments of this application provide a multi-anchor point adjustment system, including: The aforementioned multi-anchor point fixing device; The control unit is electrically connected to the drive unit 120 and the force sensor 150 respectively. The control unit can receive the signal from the force sensor 150 in real time. When the tension of the rope 140 is greater than the preset tension threshold, the control unit controls the drive unit 120 to drive the winding wheel 130 to release the rope 140. When the tension of the rope 140 is less than the preset tension threshold, the control unit controls the drive unit 120 to drive the winding wheel 130 to retract the rope 140.

[0057] The control unit is connected to the drive unit 120 and the force sensor 150 respectively. It can receive the tension measurement signal of the rope 140 collected by the force sensor 150 in real time and preset a tension threshold to determine the real-time tension status of the rope 140. When the force sensor 150 detects that the real-time tension value of the rope 140 is greater than the preset tension threshold, it means that the rope 140 is too tensile and the load stress is too high. The control unit outputs a control command to control the drive unit 120 to drive the winding wheel 130 to rotate forward to release the rope 140, appropriately reducing the tension of the rope 140 and avoiding stress concentration and deformation of the object due to excessive tension. When the force sensor 150 detects that the real-time tension value of the rope 140 is less than the preset tension threshold, it means that the rope 140 is slack and the limit switch has failed. The control unit then controls the drive unit 120 to drive the winding wheel 130 to rotate in the opposite direction to retract the rope 140, automatically tightening the rope 140, restoring the tension of the rope 140, and maintaining the effective constraint of the rope 140 on the object.

[0058] This application, through the cooperation of a control unit and a multi-anchor fixing device, enables fully automatic dynamic adjustment of the tension of rope 140, eliminating the need for frequent manual intervention by the user and enhancing the intelligence and ease of use of the anchor point 200 fixing device. It avoids problems such as rope 140 fatigue wear, anchor point 200 overload, and item crushing damage caused by excessive rope 140 tension, while also resolving issues such as rope 140 loosening, item swaying and displacement, and fixing failure caused by insufficient rope 140 tension, maintaining the rope 140 tension within a reasonable working range throughout the process. It is suitable for complex working conditions such as vehicle bumps, starts and stops, and turns, and can compensate for rope length and tension in real time, effectively ensuring the stability of items within the trunk 1.

[0059] As mentioned above, the control unit is integrated into the rewind assembly 100, or it can be integrated into the vehicle's own control system, which will not be elaborated here.

[0060] In some embodiments, the preset tension threshold is greater than or equal to 10N and less than or equal to 60N.

[0061] This application addresses the storage scenario of a vehicle's trunk 1, setting the preset tension threshold range of the rope 140 to be greater than or equal to 10N and less than or equal to 60N. This threshold is a fixed judgment parameter, and the control unit uses this threshold as an adjustment benchmark to adjust the tension of the rope 140.

[0062] Specifically, for lightweight items, i.e., items weighing less than 5 kg, such as clothing, cushions, and paper gift boxes, the preset tension threshold is set in the range of 10N to 20N, preferably 20N; for regular items, i.e., items weighing 5 kg or more but less than or equal to 15 kg, such as shopping bags, backpacks, and 20-inch trunks, the preset tension threshold is set in the range of 20N to 40N, preferably 35N; for heavy items, i.e., items weighing 15 kg or more but less than or equal to 30 kg, such as boxed beverages and 26-inch trunks, the preset tension threshold is set in the range of 40N to 60N, preferably 50N.

[0063] Based on the above, preferably, the preset tension threshold is set within the range of 20N to 50N.

[0064] In addition, the control unit can be set with multiple adjustment levels. Specifically, the control unit has light load, standard load, and heavy load levels, corresponding to the aforementioned light, regular, and heavy items, respectively. Users can select between these three levels via the vehicle display screen or an additional adjustment knob to adjust the preset tension threshold to a size suitable for the items in the trunk 1.

[0065] In some embodiments, the multi-anchor point adjustment system further includes an acceleration sensor capable of monitoring the vehicle's acceleration in real time; The acceleration sensor is electrically connected to the control unit. The control unit can receive the signal from the acceleration sensor in real time. When the acceleration is greater than the preset acceleration threshold, the control unit controls the drive component 120 to drive the winding wheel 130 to retract the rope 140.

[0066] The multi-anchor point adjustment system also includes an acceleration sensor. Specifically, the control unit can establish a communication connection with the vehicle's IMU (Inertial Measurement Unit) or ESP (Electronic Stability Program) via CAN (Controller Area Network) bus or hard-wired signal. It can obtain accurate real-time vehicle acceleration data in real time by relying on the vehicle's mature onboard sensing system, without the need for additional separate sensor acquisition devices.

[0067] The control unit has a preset acceleration threshold, which can analyze and compare the received vehicle acceleration signal in real time. When the vehicle acceleration is detected to be greater than the preset acceleration threshold, it is determined that the vehicle is in a violent driving condition such as rapid acceleration or emergency braking. At this time, the control unit actively controls the drive component 120 to drive the reel to rotate in the opposite direction, quickly tightening the rope 140, increasing the tension of the rope 140, and strengthening the restraint effect on the items inside the box.

[0068] Thirdly, embodiments of this application provide a vehicle including the aforementioned multi-anchor point adjustment system. It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms.
