Description

Technical Field

[0001] This invention relates to the field of vehicle parts technology, and more specifically, to a trunk lid opening mechanism and a vehicle. Background Technology

[0002] For vehicles with trunk lids that require manual opening, a torsion spring or gas strut is typically used to achieve manual opening. For vehicles with trunk lids that can open automatically, an electric strut is typically used to achieve automatic opening.

[0003] Currently, in order to improve the appearance of cars, more and more models are adopting structures such as rear spoilers or continuous taillights on the trunk lid to improve the car's styling. This has greatly increased the weight of the trunk lid and the support force required to open it. At the same time, it has made the installation structure of the strut (i.e., gas strut or electric strut) need to withstand a large reaction force.

[0004] In existing technologies, to increase the support force required for opening the trunk lid, a double strut configuration is typically used, with one strut on each side of the trunk lid, or a single strut with a single tension spring is used, with one strut (or tension spring) on ​​the left side of the trunk lid and one tension spring (or strut) on the right side. However, this requires increasing the thickness and structural dimensions of the strut mounting bracket, or designing multiple reinforcing brackets to improve the local rigidity of the strut mounting bracket, resulting in increased vehicle weight and development costs. This not only affects the vehicle's driving range but also hinders lightweight design. Summary of the Invention

[0005] The problem this invention addresses is: how to achieve increased support force for opening the trunk lid while using a lightweight design.

[0006] To solve the above problems, the present invention provides a trunk lid opening mechanism, including a first power assist assembly, a second power assist assembly and two hinge assemblies. The two hinge assemblies are respectively installed on both sides of the trunk lid along the left and right direction of the vehicle, and the two ends of the hinge assemblies are respectively used to hinge with the vehicle body and the trunk lid.

[0007] The first power assist assembly includes a first strut and a first tension spring. The first strut and the first tension spring are arranged in a figure-eight shape. One end of the first strut is hinged to the corresponding hinge assembly, and the other end of the first strut is hinged to the corresponding coat rack mounting structure of the vehicle body. One end of the first tension spring is connected to the hinge assembly on the corresponding side, and the other end of the first tension spring is connected to the trunk lid.

[0008] The second assist assembly includes at least one of a second strut and a second tension spring. One end of the second strut is hinged to the corresponding hinge assembly, and the other end of the second strut is hinged to the corresponding coat rack mounting structure. One end of the second tension spring is connected to the corresponding hinge assembly, and the other end of the second tension spring is connected to the luggage compartment lid.

[0009] Optionally, the first support rod is hinged to the corresponding coat rack mounting structure via a first mounting bracket. The coat rack mounting structure includes overlapping luggage compartment column connecting plates and column upper reinforcing plates. The first mounting bracket is connected at the overlapping position of the luggage compartment column connecting plate and the column upper reinforcing plate.

[0010] Optionally, the reinforcing plate on the column divides the internal space of the coat rack mounting structure into two cavities, and the first mounting bracket is located in the external space of the coat rack mounting structure.

[0011] Optionally, the first mounting bracket includes a mounting part and a connecting part, the first strut is hinged to the mounting part, the connecting part is connected to both sides of the mounting part and forms a cavity structure with the mounting part, and the connecting part is used to connect to the luggage compartment column connecting plate and the column upper reinforcing plate.

[0012] Optionally, the mounting part includes a first mounting surface with a first mounting hole and a second mounting surface with a first positioning hole, the first support rod is hinged to the first mounting hole, and the first mounting surface and the second mounting surface form a first included angle, the first included angle being between 130° and 140°.

[0013] Optionally, when the first assist assembly includes the first strut and the first tension spring, the first strut and the first tension spring are connected to opposite sides of the corresponding calibration portion of the hinge assembly.

[0014] Optionally, the hinge assembly includes a hinge body, the hinge body includes a first hinge segment and a second hinge segment, one end of the first hinge segment is connected to one end of the second hinge segment, the other end of the first hinge segment is connected to the vehicle body, the other end of the second hinge segment is connected to the trunk lid, and the dimension of the first hinge segment in the extension direction of the hinge body is smaller than the dimension of the second hinge segment in the extension direction of the hinge body, the first strut and the first tension spring are connected to the corresponding first hinge segment of the hinge body.

[0015] Optionally, one end of the first tension spring is connected to the corresponding hinge assembly via a second mounting bracket, and the other end of the first tension spring is connected to the trunk lid via a third mounting bracket.

[0016] Optionally, the second mounting bracket includes a first connecting segment, a second connecting segment, and a third connecting segment connected in sequence. The first connecting segment and the second connecting segment, and the second connecting segment and the third connecting segment are respectively set at acute angles or right angles. The first connecting segment is connected to the first tension spring, and the third connecting segment is connected to the hinge assembly along the side of the second connecting segment away from the first connecting segment.

[0017] To address the aforementioned problems, the present invention also provides a vehicle including the trunk lid opening mechanism described above.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention can be achieved by installing a first power-assist assembly and a second power-assist assembly on the left and right sides of the trunk lid, respectively, and by arranging the first support rod and the first tension spring of the first power-assist assembly in a V-shape, so that the supporting force of the first support rod and the tension force of the first tension spring can interact to provide an opening force for the trunk lid. At the same time, by installing two hinge assemblies on the left and right sides of the trunk lid, respectively, and hinge the two ends of the hinge assemblies to the trunk lid and the vehicle body structure such as a coat rack, the hinge assemblies can provide support for the trunk lid after it is opened. Furthermore, by hinged one end of the first strut in the first power assist assembly to the corresponding hinge assembly and the other end to the corresponding coat rack mounting structure, and when the second power assist assembly includes a second strut, one end of the second strut is hinged to the corresponding hinge assembly and the other end to the corresponding coat rack mounting structure. This allows the coat rack mounting structure to enhance the rigidity of the end of the strut connected to the vehicle body, i.e., the rigidity of the strut mounting bracket. This enables the coat rack mounting structure to share the reaction force of the strut, reducing the reaction force and allowing both the first and second power assist assemblies to provide greater support for opening the trunk lid. Compared to existing technologies that use reinforcing brackets or increase the thickness of the strut mounting bracket to improve rigidity at the strut mounting bracket, this approach simplifies the structure at the strut mounting bracket, reduces the number of parts, and achieves the goal of reducing overall vehicle weight and development costs, facilitating lightweight vehicle design.

[0033] In the attached figures, the Z-axis represents the vertical direction, i.e., the up-down position, with the positive direction of the Z-axis (i.e., the direction the arrow points) representing upwards and the negative direction representing downwards. The X-axis represents the horizontal direction and is designated as the front-back position, with the positive direction of the X-axis representing the front and the negative direction representing the back. The Y-axis represents the left-right position, with the positive direction of the Y-axis representing the right and the negative direction representing the left. It should be noted that the aforementioned representations of the Z, Y, and X axes are only for the convenience of describing the present invention 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 limiting the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0035] Combination Figure 1 As shown, this embodiment of the invention provides a trunk lid opening mechanism, including a first assist assembly 1, a second assist assembly 2, and two hinge assemblies 3. The two hinge assemblies 3 are respectively mounted on both sides of the trunk lid 500 along the left-right direction of the vehicle, and both ends of the hinge assemblies 3 are respectively hinged to the vehicle body and the trunk lid 500. The first assist assembly 1 includes a first support rod 11 and a first tension spring 12, which are arranged in a V-shape. One end of the first support rod 11 is hinged to the corresponding hinge assembly 3. The other end of the strut 11 is hinged to the corresponding coat rack mounting structure 600 of the vehicle body. One end of the first tension spring 12 is connected to the corresponding hinge assembly 3, and the other end of the first tension spring 12 is connected to the trunk lid 500. The second assist assembly 2 includes at least one of the second strut and the second tension spring. One end of the second strut is hinged to the corresponding hinge assembly 3, and the other end of the second strut is hinged to the corresponding coat rack mounting structure 600. One end of the second tension spring is connected to the corresponding hinge assembly 3, and the other end of the second tension spring is connected to the trunk lid 500.

[0036] It should be noted that the vehicle's left and right directions are... Figure 1 In the Y-axis direction, correspondingly, the vehicle's forward and backward direction is... Figure 1 In the X-axis direction, the vertical direction of the vehicle is... Figure 1 In the Z-axis direction.

[0037] Specifically, the first strut 11 and the second strut can be electric struts. In this case, the trunk lid opening mechanism is suitable for vehicles with electrically operated trunk lids. Alternatively, the first strut 11 and the second strut can be gas struts. In this case, the trunk lid opening mechanism is suitable for vehicles with manually operated trunk lids. For example, Figure 1 and Figure 2 The example given is that the first support rod 11 is an electric support rod. When the trunk lid 500 is closed, the tension spring is in its maximum tension state. When the trunk lid 500 is unlocked, the trunk lid 500, together with the tension spring and the support rod, rotates counterclockwise around the hinge axis where the trunk lid 500 is hinged to the vehicle body. In the design matching, the torque of the tension spring is slightly less than the gravitational torque of the trunk lid. Therefore, the trunk lid 500 needs to be opened by the force of the support rod. For models where the trunk lid 500 is opened manually, the force of the support rod is the force provided by the user when lifting the trunk lid 500. For models where the trunk lid 500 is opened automatically, the force of the support rod is the force provided by the motor driving the electric support rod to push the hinge assembly 3.

[0038] More specifically, the luggage compartment lid opening mechanism is located within the luggage compartment. The first assist assembly 1 and the second assist assembly 2 are respectively installed on the left and right sides of the luggage compartment lid 500. The hinge assembly 3 is typically a gooseneck hinge, and the two hinge assemblies 3 are usually installed on the left and right sides of the luggage compartment lid 500, corresponding to the first assist assembly 1 and the second assist assembly 2. For ease of description, this section and the following description will use the example of the first assist assembly 1 being installed on the right side of the luggage compartment lid 500 and the second assist assembly being installed on the left side. The right side of the luggage compartment lid 500 is equipped with both the first support rod 11 and the first tension spring 12. The left side of the luggage compartment lid 500 can be equipped with either the second support rod and the second tension spring; that is, it can be equipped with both the second support rod and the second tension spring, or only the second support rod, or only the second tension spring. In other words, the opening of the luggage compartment lid 500 can be achieved using a structure of double struts + double tension springs, single struts + double tension springs, or double struts + single tension springs. For example, Figure 1The document provides an example where the right side of the trunk lid 500 is equipped with both the first support rod 11 and the first tension spring 12, while the left side is equipped with only the second tension spring; this illustrates a single support rod + double tension spring configuration. Furthermore, the first support rod 11 is typically positioned in front of the first tension spring 12, forming an obtuse angle with it, with the opening of the obtuse angle facing away from the end of the hinge assembly 3 connected to the vehicle body. Similarly, the second support rod is typically positioned in front of the second tension spring, also forming an obtuse angle with it, with the opening of the obtuse angle facing away from the end of the hinge assembly 3 connected to the vehicle body. In other words, the support rod and tension spring are arranged in opposite directions, forming a V-shape. Additionally, a coat rack mounting structure 600 is provided on each of the left and right sides of the coat rack 700 to connect the coat rack 700 to the side panel and floor wheel arch 800. One end of the first support rod 11 is hinged to the hinge assembly 3 on the right side, and the other end is hinged to the coat rack mounting structure 600 on the right side. When the second support rod is installed on the left side of the luggage compartment lid 500, one end of the second support rod is hinged to the hinge assembly 3 on the left side, and the other end is hinged to the coat rack mounting structure 600 on the left side.

[0039] In this embodiment, the first assist assembly 1 and the second assist assembly 2 can be respectively installed on the left and right sides of the trunk lid 500, and the first support rod 11 and the first tension spring 12 of the first assist assembly 1 can be arranged in a V-shape so that the supporting force of the first support rod 11 and the tension of the first tension spring 12 can interact with each other to provide an opening force for the trunk lid 500. At the same time, by installing the two hinge assemblies 3 on the left and right sides of the trunk lid 500 respectively, and hinge the two ends of the hinge assembly 3 to the trunk lid 500 and the body structure such as the coat rack 700, the hinge assembly 3 can provide support for the trunk lid 500 after it is opened. Furthermore, by hinged one end of the first strut 11 in the first power assist assembly 1 to the corresponding hinge assembly 3 and the other end to the corresponding coat rack mounting structure 600, when the second power assist assembly 2 includes the second strut, one end of the second strut is hinged to the corresponding hinge assembly 3 and the other end is hinged to the corresponding coat rack mounting structure 600. In this way, the coat rack mounting structure 600 can be used to enhance the rigidity of the end of the strut connected to the vehicle body, that is, the rigidity of the strut mounting bracket (also the first mounting bracket 114 described later). Thus, the coat rack mounting structure 600 can be used to share the reaction force of the strut, thereby reducing the reaction force of the strut. This allows the first power assist assembly 1 and the second power assist assembly 2 to provide greater support force to open the trunk lid 500. Compared with existing technologies that use additional reinforcing brackets or increased thickness of strut mounting brackets to improve the rigidity of the strut mounting bracket, this not only simplifies the structure of the strut mounting bracket but also reduces the number of parts, thereby reducing the overall vehicle weight and development costs and facilitating the lightweight design of the entire vehicle.

[0040] Optionally, combined Figures 2 to 4 As shown, the first support rod 11 is hinged to the corresponding coat rack mounting structure 600 via the first mounting bracket 114. The coat rack mounting structure 600 includes an overlapping luggage compartment column connecting plate 610 and a column upper reinforcing plate 620. The first mounting bracket 114 is connected at the overlapping position of the luggage compartment column connecting plate 610 and the column upper reinforcing plate 620.

[0041] In this embodiment, the first support rod 11 typically includes a first support rod body 111, a first ball joint pin 112, and a second ball joint pin 113. One end of the first support rod body 111 is hinged to the first mounting bracket 114 via the first ball joint pin 112, and the other end is hinged to the corresponding hinge assembly 3 via the second ball joint pin 113, thus achieving the installation and fixation of the first support rod 11. The luggage compartment column connecting plate 610 and the column upper reinforcing plate 620 of the coat rack mounting structure 600 are located below the left / right side of the coat rack 700. The luggage compartment column connecting plate 610 is welded to the column upper reinforcing plate 620. A portion of the first mounting bracket 114 is typically welded to the column upper reinforcing plate 620, and another portion is also typically welded to the position where the luggage compartment column connecting plate 610 overlaps with the column upper reinforcing plate 620. This allows any two of the first mounting bracket 114, the luggage compartment column connecting plate 610, and the column upper reinforcing plate 620 to be connected, which not only further enhances the rigidity of the strut mounting bracket, but also ensures the stability of the strut when it is connected to the coat rack mounting structure 600.

[0042] Optionally, combined Figure 4 and Figure 5 As shown, the reinforcing plate 620 on the column divides the internal space of the coat rack mounting structure 600 into two cavities, and the first mounting bracket 114 is located in the external space of the coat rack mounting structure 600.

[0043] In this embodiment, the coat rack mounting structure 600 further includes a seat belt mounting bracket located above the upper reinforcing plate 620 of the column and a rear connecting plate 630 of the column connected to the rear side of the luggage compartment column connecting plate 610. The upper reinforcing plate 620 of the column and the seat belt mounting bracket form a first cavity, and the upper reinforcing plate 620 of the column, the luggage compartment column connecting plate 610 and the rear connecting plate 630 of the column form a second cavity, with the first cavity located above the second cavity. Thus, the coat rack mounting structure 600 is designed as a hollow structure with two cavities, which further enhances the rigidity of the first mounting bracket 114 by increasing the local rigidity of the coat rack mounting structure 600. Simultaneously, the first mounting bracket 114 is placed in the external space of the coat rack mounting structure 600 for easy assembly and disassembly.

[0044] Optionally, combined Figure 4 and Figure 6 As shown, the first mounting bracket 114 includes a mounting part 1141 and a connecting part 1142. The first support rod 11 is hinged to the mounting part 1141. The connecting part 1142 is connected to both sides of the mounting part 1141 and forms a cavity structure with the mounting part 1141. The connecting part 1142 is used to connect with the luggage compartment pillar connecting plate 610 and the pillar upper reinforcing plate 620.

[0045] In this embodiment, one end of the first strut body 111 is hinged to the mounting part 1141 via the first ball joint pin 112. The connecting part 1142 is typically connected to the front and rear sides of the mounting part 1141 and forms a cavity structure with the mounting part 1141. This cavity structure can be... Figure 6 The diagram shows a U-shaped structure where the two connecting parts 1142 are approximately parallel to the luggage compartment pillar connecting plate 610. This cavity structure can also be an inverted U-shaped structure, in which case the two connecting parts 1142 are approximately perpendicular to the luggage compartment pillar connecting plate 610. Alternatively, the cavity structure can be a square-shaped structure, in which case the two ends of one connecting part 1142 are connected to the front and rear sides of the mounting part 1141, respectively. Furthermore, a portion of the connecting part 1142 is connected to the luggage compartment pillar connecting plate 610, and another portion is connected to the pillar reinforcement plate 620. For example, in one example, the connecting part 1142 located in front of the mounting part 1141 is connected to the luggage compartment pillar connecting plate 610, and the left half of the connecting part 1142 located behind the mounting part 1141 is connected to the luggage compartment pillar connecting plate 610, while the right half is connected to the pillar reinforcement plate 620. In this way, by setting the first mounting bracket 114 as a cavity structure such as a Z-shape, the local rigidity of the first mounting bracket 114 at the mounting part 1141 is improved, thereby improving the structural strength of the support rod connected to the coat rack mounting structure 600. Moreover, the structure is simple and easy to process and manufacture.

[0046] Optionally, combined Figure 6 As shown, the mounting part 1141 includes a first mounting surface with a first mounting hole 1141a and a second mounting surface with a first positioning hole 1141b. The first support rod 11 is hinged at the first mounting hole 1141a, and the first mounting surface and the second mounting surface form a first included angle, which is between 130° and 140°.

[0047] In this embodiment, one end of the first support rod body 111 is hinged to the first mounting hole 1141a of the mounting part 1141 via the first ball-head pin 112. When welding the first mounting bracket 114 to the coat rack mounting structure 600, the first mounting bracket 114 can be positioned first using the first positioning hole 1141b before welding to ensure welding accuracy. Simultaneously, the first mounting surface with the first mounting hole 1141a and the second mounting surface with the first positioning hole 1141b are set at an angle, making the mounting part 1141 approximately triangular in shape. This further enhances the local rigidity of the first mounting bracket 114 at the mounting part 1141. Furthermore, this angle is set between 130° and 140° to prevent the angle from being too large and failing to enhance structural strength, or to prevent the angle from being too small and increasing the protrusion height of the mounting part 1141 or even the overall volume of the first mounting bracket 114.

[0048] Furthermore, combined Figure 4 , Figure 6 and Figure 7 As shown, the first ball head pin 112 includes a seat body 1121 and a first ball head 1122 connected to each other. The first support rod body 111 and the first ball head 1122 form a ball joint connection. The seat body 1121 is provided with a snap-fit ​​structure 1121a, which snaps into the first mounting hole 1141a.

[0049] In this embodiment, the first ball head pin 112 has a tower-like structure. The base 1121 is typically cylindrical, the portion of the first ball head 1122 used for connection is roughly a frustum conical, and the portion of the first ball head 1122 used for ball-joint connection with the first strut body 111 is spherical. The snap-fit ​​structure 1121a is typically an annular groove along the circumference of the base 1121, dividing the base 1121 into upper and lower parts. The lower half of the base 1121 is located within the cavity formed by the U-shaped structure, while the upper half is located outside the cavity. The portion of the base 1121 at the annular groove is snapped into the first mounting hole 1141a. Thus, the snap-fit ​​connection between the first ball head pin 112 and the first mounting bracket 114 is achieved, ensuring the first ball head pin 112 is firmly fixed to the first mounting bracket 114.

[0050] Furthermore, combined Figure 3 and Figure 8As shown, the second ball joint pin 113 includes a first base 1131, a second base 1132, and a second ball joint 1133 connected in sequence. The first base 1131 is connected to the hinge assembly 3 on the corresponding side. The first strut body 111 and the second ball joint 1133 form a ball joint connection. The first base 1131 and the second base 1132 are coaxially arranged, and the cross-sectional area of ​​the first base 1131 is larger than the cross-sectional area of ​​the second base 1132. The cross-section of the first base 1131 is the cross-section of the first base 1131 on a plane perpendicular to its axial direction, and the cross-section of the second base 1132 is the cross-section of the second base 1132 on a plane perpendicular to its axial direction.

[0051] In this embodiment, the second ball head pin 113 has a tower-like structure. The first base 1131 and the second base 1132 are typically coaxially arranged cylindrical structures. The first base 1131 is usually fixed to the hinge body 31 of the hinge assembly 3 (described later) by welding. The part of the second ball head 1133 used to connect with the second base 1132 is roughly a frustum-shaped structure, and the part of the second ball head 1133 used to connect with the first strut body 111 by ball joint is spherical. The diameter of the first base 1131 is larger than the diameter of the second base 1132. For example, the diameter of the first base 1131 can be set to 20mm, and the diameter of the second base 1132 can be set to 15mm. Since the size of the base is related to the strength of the strut mounting point, in practical applications, the diameter of the base can be determined according to the actual strength required at the strut mounting point. This design simplifies the structure of the second ball joint 113 while ensuring that it can withstand the reaction force of the strut, making it easier to manufacture.

[0052] Furthermore, combined Figure 3 and Figure 8 As shown, the second ball head pin 113 also includes a positioning seat 1134, which is connected to the side of the first base 1131 opposite to the second base 1132. The hinge assembly 3 has a second positioning hole, and the positioning seat 1134 is inserted into the second positioning hole. In this way, before welding the second ball head pin 113 to the hinge assembly 3, the positioning seat 1134 can be inserted into the second positioning hole to position the second ball head pin 113, ensuring the accuracy of the welding position of the second ball head pin 113 and improving the welding precision.

[0053] Optionally, combined Figure 2 and Figure 3 As shown, the first strut 11 and the first tension spring 12 are connected to opposite sides of the corresponding hinge assembly 3 at the designated locations.

[0054] In this embodiment, the calibrated part of the hinge assembly 3 refers to the part on the hinge body 31 (described later) of the hinge assembly 3 that is used to connect with the first support rod 11 and the first tension spring 12. When the first support rod 11 and the first tension spring 12 are arranged on the right side of the trunk lid 500, the first support rod 11 and the first tension spring 12 are respectively connected to the left and right sides of the same part of the right hinge assembly 3. This makes the part of the right hinge assembly 3 that is used to connect with the first support rod 11 and the part that is used to connect with the first tension spring 12 basically consistent in the X-axis coordinate of the vehicle, ensuring that the force provided by the first support rod 11 and the first tension spring 12 acts on the same point and reducing the loss of force.

[0055] Optionally, combined Figure 2 and Figure 3 As shown, the hinge assembly 3 includes a hinge body 31, which includes a first hinge segment and a second hinge segment. One end of the first hinge segment is connected to one end of the second hinge segment, and the other end of the first hinge segment is connected to the vehicle body. The other end of the second hinge segment is connected to the trunk lid 500. The dimension of the first hinge segment in the extension direction of the hinge body 31 is smaller than the dimension of the second hinge segment in the extension direction of the hinge body 31. The first strut 11 and the first tension spring 12 are connected to the first hinge segment of the corresponding hinge body 31.

[0056] In this embodiment, the hinge assembly 3 includes a hinge body 31, a first hinge bracket 32, and a second hinge bracket. One end of the hinge body 31 is connected to the trunk lid 500 via the first hinge bracket 32, and the other end is connected to the coat rack 700 of the vehicle body via the second hinge bracket. The hinge body 31 typically has a gooseneck-shaped structure. Considering the hinge body 31 as a bent rod, the first hinge segment and the second hinge segment are two bent rods. The extension direction of the bent rod can be understood as the direction of the bent rod or the bending direction; that is, the extension direction of the hinge body 31 can also be understood as the direction of the hinge body 31 or the bending direction. The dimension of the first hinge segment in the extension direction of the hinge body 31 is the same as the length of the first hinge segment in the bending direction of the hinge body 31. Similarly, the dimension of the second hinge segment in the extension direction of the hinge body 31 is the same as the length of the second hinge segment in the bending direction of the hinge body 31. Furthermore, the length of the first hinge segment in the bending direction of the hinge body 31 is less than the length of the second hinge segment in the bending direction of the hinge body 31, and the first support rod 11 and the first tension spring 12 are connected to the first hinge segment of the hinge body 31 on the corresponding side. In this way, by connecting the first support rod 11 and the first tension spring 12 to the hinge body 31 on the corresponding side as close as possible to the end of the hinge body 31 that is connected to the vehicle body, it is beneficial to reduce the travel of the first support rod 11 and reduce the support force of the first support rod 11.

[0057] Optionally, combined Figure 2 and Figure 3As shown, one end of the first tension spring 12 is connected to the corresponding hinge assembly 3 via the second mounting bracket 122, and the other end of the first tension spring 12 is connected to the trunk lid 500 via the third mounting bracket 123.

[0058] In this embodiment, the second mounting bracket 122 and the third mounting bracket 123 are typically provided with mounting hole structures, and the two ends of the first tension spring 12 are typically bent into hook structures. By engaging the hook structures at both ends of the first tension spring 12 into the mounting hole structures on the second mounting bracket 122 and the third mounting bracket 123 respectively, the first tension spring 12 is installed and fixed. In this way, connecting the two ends of the first tension spring 12 to the hinge assembly 3 and the trunk lid 500 respectively through the brackets not only facilitates the installation and removal of the first tension spring 12, but also avoids the hook structures at both ends of the first tension spring 12 from directly rubbing against the hinge assembly 3 and the trunk lid 500.

[0059] Optionally, combined Figure 3 and Figure 9 As shown, the second mounting bracket 122 includes a first connecting segment 1221, a second connecting segment 1222, and a third connecting segment 1223 connected in sequence. The first connecting segment 1221 and the second connecting segment 1222, and the second connecting segment 1222 and the third connecting segment 1223 are respectively set at acute angles or right angles. The first connecting segment 1221 is connected to the first tension spring 12. The third connecting segment 1223 is connected to the hinge assembly 3 along the side away from the first connecting segment 1221 along the length direction of the second connecting segment 1222.

[0060] In this embodiment, the first connecting segment 1221 and the second connecting segment 1222, and the second connecting segment 1222 and the third connecting segment 1223 are respectively set at acute angles or right angles, so that the first connecting segment 1221, the second connecting segment 1222, and the third connecting segment 1223 can be connected sequentially to form a Z-shaped structure or a C-shaped structure. The Z-shaped structure includes a Z-like structure, that is, the middle part of the Z-shape used to connect the upper and lower horizontal parts is set vertically. The opening of the C-shaped structure can be set forward or backward. The mounting hole structure for fixing the hook structure at the end of the first tension spring 12 is set on the first connecting segment 1221, and the third connecting segment 1223 is usually connected to the left side of the hinge body 31 by a weld point. In this way, by setting the second mounting bracket 122 as, for example, a Z-shaped or C-shaped structure, the structural strength of the second mounting bracket 122 is improved by utilizing the multiple bends of the Z-shaped or C-shaped structure. Moreover, by connecting the third connecting segment 1223 to the hinge body 31 along the side opposite to the first connecting segment 1221 in the length direction of the second connecting segment 1222, not only is a surface-to-surface contact formed between the second mounting bracket 122 and the hinge body 31, thereby increasing the connection area and ensuring the stability of the connection, but also by arranging the Z-shaped or C-shaped structure along the left and right directions of the vehicle, the stiffness of the second mounting bracket 122 in the left and right directions can be improved.

[0061] Furthermore, combined Figure 9 As shown, the second connecting section 1222 is provided with a reinforcing rib 1222a, which extends along the length of the second connecting section 1222. This increases the rigidity of the middle part of the second mounting bracket 122, thereby increasing the rigidity of the second mounting bracket 122 in the left-right direction of the vehicle, ensuring a stable connection between the first tension spring 12 and the hinge assembly 3.

[0062] Furthermore, flange structures 1224 are provided on opposite sides of the first connecting segment 1221, the second connecting segment 1222, and the third connecting segment 1223. In this embodiment, the flange structures 1224 are typically provided on both sides of the first connecting segment 1221, the second connecting segment 1222, and the third connecting segment 1223 along the vertical direction of the vehicle, thereby improving the rigidity of the second mounting bracket 122 along the vertical direction of the vehicle.

[0063] Furthermore, when the second assist assembly 2 includes a second strut and a second tension spring, the second strut and the second tension spring are connected to opposite sides of the calibration location of the corresponding hinge assembly 3.

[0064] In this embodiment, when the first assist assembly 1 includes a first support rod 11 and a first tension spring 12, and the second assist assembly 2 includes a second support rod and a second tension spring, the first assist assembly 1 and the second assist assembly 2 are usually symmetrically arranged on the left and right sides of the trunk lid 500. That is, the arrangement of the second support rod and the second tension spring is the same as the arrangement of the first support rod 11 and the first tension spring 12. The parts where the second support rod and the second tension spring are hinged to the corresponding hinge assembly 3 are the same as the parts where the first support rod 11 and the first tension spring 12 are hinged to the corresponding hinge assembly 3, which will not be described again here.

[0065] Furthermore, the structure of the second strut is generally the same as that of the first strut 11, and will not be described in detail here.

[0066] Another embodiment of the present invention provides a vehicle including the trunk lid opening mechanism described above.

[0067] In this embodiment, the vehicle also includes a trunk lid 500, a coat rack mounting structure 600, a coat rack 700, and a floor wheel cover 800. The coat rack 700 is connected to the floor wheel cover 800 via the coat rack mounting structure 600. The first assist assembly 1 and the second assist assembly 2 of the trunk lid opening mechanism are respectively installed on the left and right sides of the trunk lid 500, and two hinge assemblies 3 are also respectively installed on the left and right sides of the trunk lid 500, corresponding to the first assist assembly 1 and the second assist assembly 2. Taking the first assist assembly 1 installed on the right side of the trunk lid 500 and the second assist assembly installed on the left side of the trunk lid 500 as an example, the right side of the trunk lid 500 is equipped with both a first support rod 11 and a first tension spring 12, while the left side of the trunk lid 500 can be equipped with a second support rod and / or a second tension spring. Furthermore, one end of the first support rod 11 / second support rod is hinged to the corresponding hinge assembly 3, and the other end of the first support rod 11 / second support rod is hinged to the corresponding coat rack mounting structure 600. Additionally, the beneficial effects of the vehicle in this embodiment compared to the prior art are the same as those of the aforementioned trunk lid opening mechanism, and will not be repeated here.

[0068] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
