Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a front hood assembly and a vehicle. Background Technology

[0002] With the continuous development of new energy vehicles, lightweighting has become an inevitable requirement for improving their driving range. While ensuring vehicle safety, the thickness of the front hood outer panel is becoming increasingly thinner, affecting its rigidity and causing issues such as softness upon pressure and a creaking sound upon rebound. Related technologies incorporate support structures within the front hood outer and inner panels to increase rigidity; however, these structures cannot adjust the rigidity of the outer panel and cannot flexibly adapt to the rigidity support requirements during production, assembly, or after-sales service.

One end of the first adjusting member passes through the hollow space and is movably connected to the fixed seat. The operating end is located on the side of the first adjusting member away from the fixed seat.

[0021] In some embodiments, the support member includes a limiting end disposed on the side of the support member away from the outer front cover panel. The limiting end is located outside the mounting cavity and inside the open groove.

[0022] And / or, the second adjusting member is provided with a limiting structure, the limiting structure being disposed on the outside of the open groove, the outer side wall of the second adjusting member protruding outward to form the limiting structure, the limiting structure being used to detachably engage with the top end of the first adjusting member to limit the movement displacement of the first adjusting member along the top-bottom direction.

[0040] One embodiment of this application provides a front hood assembly 10 for a vehicle.

[0041] Please see Figures 1 to 8 The front hood assembly 10 includes an inner front hood panel 12, an outer front hood panel 11, and a rigid adjustment mechanism 13.

[0042] Please see Figures 1 to 3 The inner front cover panel 12 is connected to the bottom of the outer front cover panel 11, and a cavity 10a is formed between the inner front cover panel 12 and the outer front cover panel 11.

[0043] The edges of the outer front cover panel 11 and the inner front cover panel 12 can be fixed by edge binding and folding adhesive bonding. The cavity 10a formed between the outer front cover panel 11 and the inner front cover panel 12 allows the outer front cover panel 11 to deform and provides installation space for the rigid adjustment mechanism 13.

[0044] It should be noted that the front hood outer panel 11 and front hood inner panel 12 in this embodiment adopt the original front hood outer panel 11 and front hood inner panel 12 on existing vehicles. The structure and installation method of the front hood outer panel 11 and front hood inner panel 12 are not changed, which is convenient for production and will not affect the overall shape of the vehicle.

[0045] Understandably, the inner panel of the front hood has high rigidity and is not easily deformed, while the outer panel is thinner and prone to issues such as being soft when pressed or making a popping sound when rebounding, affecting the overall vehicle quality and lacking reliable after-sales repair methods. Related technologies incorporate a bracket structure within the cavity to support the outer panel, but this design only increases the rigidity of the outer panel and cannot be adjusted. If the bracket structure design is flawed, significant costs and time are required for rectification and optimization. It cannot adaptively adjust the rigidity of the outer panel during production, assembly, and after-sales processes, leading to high vehicle design complexity and high after-sales costs.

[0046] Therefore, in this embodiment of the application, a rigidity adjustment mechanism 13 is provided to support the outer front cover panel 11 and adjust the supporting force on the outer front cover panel 11. During the production and assembly of the front cover assembly 10, the rigidity of the outer front cover panel 11 is adjusted so that the rigidity of the outer front cover panel 11 meets the target requirements. It can also be used to adjust the assembly of vehicles with a soft outer front cover panel 11 or a rebound noise during after-sales service, thereby reducing after-sales costs.

[0047] Please see Figures 3 to 8 The rigid adjustment mechanism 13 includes a stroke adjustment mechanism, a support member 131, and an elastic member 132. The stroke adjustment mechanism passes through the cavity 10a and is connected to the inner panel 12 of the front cover. The stroke adjustment mechanism is provided with a mounting cavity 135b. At least a portion of the support member 131 is disposed in the cavity 10a. One end of the support member 131 is connected to the outer panel 11 of the front cover, and the other end passes through the mounting cavity 135b. One end of the elastic member 132 abuts against the stroke adjustment mechanism, and the other end cooperates with the support member 131.

[0048] The stroke adjustment mechanism has an operating end 1341, which is located on the side of the inner front cover panel 12 away from the outer front cover panel 11. The operating end 1341 can drive at least a part of the stroke adjustment mechanism to generate displacement relative to the support member 131 in the top-bottom direction under the action of external force, so as to adjust the elastic force of the elastic member 132 transmitted to the outer front cover panel 11 through the support member 131.

[0049] The support member 131 is connected to the outer front cover panel 11 and passes through the mounting cavity 135b. That is, the rigid adjustment mechanism 13 transmits the supporting force to the outer front cover panel 11 through the support member 131. For example, the support member 131 is a rigid member.

[0050] The support member 131 can be fixed relative to the outer front cover panel 11, that is, there is no relative movement between the support member 131 and the outer front cover panel 11. Of course, there is also no relative movement between the support member 131 and the inner front cover panel 12.

[0051] The operating end 1341 is located on the side of the inner front cover panel 12 away from the outer front cover panel 11, meaning the operating end 1341 can be located outside the cavity 10a and is exposed on the outer surface of the front cover assembly 10. Thus, when adjusting the outer front cover panel 11 during production assembly or after-sales service, the operator can apply external force to the stroke adjustment mechanism through the operating end 1341, causing at least a portion of the stroke adjustment mechanism to displace relative to the support member 131 at least in the top-to-bottom direction. This changes the elastic force of the elastic member 132, thereby altering the supporting force transmitted from the support member 131 to the outer front cover panel 11, thus adaptively adjusting the rigidity of the outer front cover panel 11.

[0052] It should be noted that the external force can be the operator's hand force or the force applied by the operator to the operating end 1341 through the operating tool.

[0053] At least a portion of the stroke adjustment mechanism moves relative to the support member 131 under the action of an external force. Here, it can be a partial structure of the stroke adjustment mechanism moving relative to the support member 131, or it can be the entire stroke adjustment mechanism moving relative to the support member 131. For example, the structure of the stroke adjustment mechanism used to connect with the inner front cover panel 12 is fixed relative to the inner front cover panel 12, that is, this part of the structure is fixed relative to the support member 131, while the remaining part of the stroke adjustment mechanism moves relative to the support member 131, the inner front cover panel 12, and the outer front cover panel 11.

[0054] It should be noted that the movement of at least a portion of the stroke adjustment mechanism relative to the support member 131 is not limited; it can be sliding, rotating, or a combination of both, as long as it can generate at least a displacement along the top-bottom direction. Here, generating at least a displacement along the top-bottom direction means that it can be a displacement only along the top-bottom direction, or it can be a superposition of displacement along the top-bottom direction and displacement perpendicular to the top-bottom direction. The support member 131 passes through the mounting cavity 135b, which can provide a certain guiding effect for the movement of the stroke adjustment mechanism and increase the stability of the movement, so that the rigid adjustment mechanism 13 can provide rigid support for the front cover outer plate 11 as a whole.

[0055] The elastic element 132 is disposed on the movement path of the stroke adjustment mechanism. One end of the elastic element 132 abuts against the stroke adjustment mechanism, and the other end cooperates with the support element 131. The elastic element 132 can undergo adaptive deformation under the movement of the stroke adjustment mechanism, and the elastic force of the elastic element 132 has at least a component force along the top and bottom direction, so as to be transmitted to the front cover outer plate 11 on the top side through the support element 131.

[0056] The way the elastic element 132 and the support element 131 are matched is not limited. It can be abutting or abutting and sleeved. There is no restriction here, as long as the elastic force of the elastic element 132 can act on the support element 131.

[0057] The front hood assembly 10 provided in this application embodiment changes the relative position between at least a portion of the stroke adjustment mechanism and the support member 131 through relative movement, thereby changing the elastic force of the elastic member 132 and adjusting the supporting force transmitted to the outer front hood panel 11 through the support member 131. This allows for adjustment of the rigidity of the outer front hood panel 11 during production and assembly, adapting to the increasingly thinner rigidity requirements of the outer front hood panel 11, reducing the difficulty and time required for developing different vehicle models. It also allows for assembly adjustments to areas of the outer front hood panel 11 that are too soft or have a rebound noise during after-sales service, reducing after-sales costs. Furthermore, the rigidity adjustment mechanism 13 in this application embodiment is reusable and can be modularly produced as a separate module, applicable to multiple vehicle models, and highly versatile. The position of the rigidity adjustment mechanism 13 can be flexibly arranged according to the vehicle's shape, with fewer structural restrictions on the outer front hood panel 11 and the inner front hood panel 12.

[0058] In some embodiments, please refer to Figures 3 to 5 The support member 131 includes a support end 1311, which is connected to the front cover outer panel 11. The support end 1311 has a glue groove 1311a on the side facing the front cover outer panel 11. The rigidity adjustment mechanism 13 includes adhesive 136, which is disposed in the glue groove 1311a to connect the support member 131 and the front cover outer panel 11.

[0059] In this embodiment, the support member 131 and the front cover outer panel 11 are connected by adhesive 136. In this way, the connection stability between the support member 131 and the front cover outer panel 11 is high, and there will be no relative movement between the support member 131 and the front cover outer panel 11. At the same time, it is also convenient for the support member 131 to transmit the supporting force to the front cover outer panel 11 and adjust the rigidity of the front cover outer panel 11.

[0060] In some embodiments, the other end of the elastic element 132 abuts against the end of the support element 131 near the inner front cover plate 12. That is, in this embodiment, the entire elastic element 132 is located on the bottom side of the support element 131, and the support element 131 and the elastic element 132 are engaged by abutment. In this embodiment, the size of the elastic element 132 can be smaller, increasing the structural compactness.

[0061] In other embodiments, please refer to Figures 3 to 5 The other end of the elastic member 132 abuts against the end of the support member 131 away from the inner front cover plate 12.

[0062] It is understandable that the end of the support member 131 that is away from the inner front panel 12 is the aforementioned support end 1311.

[0063] In this embodiment, the elastic element 132 and the support element 131 have overlapping dimensions along the top and bottom directions. This allows the elastic element 132 to be longer, increasing its stability. Furthermore, the elastic force of the elastic element 132 can directly act on the support end 1311, and subsequently on the front cover outer panel 11, reducing the transmission path. Simultaneously, the elastic element 132 and the support element 131 can be coupled in abutment or a combination of abutment and sleeve, facilitating the arrangement of the elastic element 132.

[0064] For example, in some embodiments, please refer to Figures 3 to 5 The support member 131 includes a support end 1311 and a guide post 1312. The support member 131 is connected to the outer front cover plate 11 through the support end 1311. One end of the guide post 1312 is connected to the support end 1311, and the other end passes through the mounting cavity 135b. The elastic member 132 is sleeved on the outside of the guide post 1312 and abuts against the support end 1311 and the stroke adjustment mechanism.

[0065] For example, please refer to Figure 3 and Figure 4 The elastic element 132 is sleeved on the outside of the guide post 1312. One end of the elastic element 132 abuts against the support end 1311, and the other end is disposed in the mounting cavity 135b.

[0066] It is understandable that the extension direction of the guide post 1312 can be the displacement direction generated by the stroke adjustment mechanism. The extension direction of the guide post 1312 can be the same as the top and bottom direction, or it can be arranged at an acute angle to the top and bottom direction.

[0067] In this embodiment, the elastic element 132 and the support element 131 are coupled by a combination of sleeve and abutment. The guide column 1312 not only provides guidance for the movement of the stroke adjustment mechanism, but also increases the stability of the elastic element 132 and reduces the probability of the elastic element 132 accidentally coming off, so as to stabilize the rigid support force of the rigid adjustment mechanism 13 on the front cover outer plate 11.

[0068] The specific construction of the elastic element 132 is not limited; for example, please refer to [link to relevant documentation]. Figure 3 and Figure 4 The elastic element 132 can be a spring.

[0069] It is understandable that, along the top-bottom direction, the size of the support member 131 at the support end 1311 is larger than the size of the support member 131 at the guide post 1312. This is to ensure stable contact with the elastic member 132 and prevent the elastic member 132 from coming out. At the same time, it also increases the area of ​​the rubber groove 1311a at the support end 1311, so as to facilitate the connection between the rigid adjustment mechanism 13 and the front cover outer panel 11.

[0070] In some embodiments, please refer toFigure 4 and Figure 8 The rigid adjustment mechanism 13 includes a first pad 137, which is disposed between the elastic member 132 and the support end 1311.

[0071] In this embodiment, the first gasket 137 can reduce the wear of the elastic element 132 on the support end 1311, extend the service life of the support element 131, and at the same time facilitate the effective transmission of rigid support force by the support end 1311.

[0072] For example, the first gasket 137 can be a rigid element.

[0073] In some embodiments, please refer to Figure 4 and Figure 8 The rigid adjustment mechanism 13 includes a second shim 138, which is disposed between the elastic member 132 and the stroke adjustment mechanism.

[0074] In this embodiment, the provision of the second shim 138 can reduce the wear of the elastic element 132 on the stroke adjustment mechanism, extend the service life of the stroke adjustment mechanism, and increase the structural reliability of the rigid adjustment mechanism 13.

[0075] For example, the second gasket 138 can be a rigid member.

[0076] It is understood that in embodiments where the other end of the elastic member 132 is disposed within the mounting cavity 135b, please refer to [reference needed]. Figure 8 A positioning structure 1352 can be provided in the mounting cavity 135b. The second gasket 138 can cooperate with the positioning structure 1352 to limit the position of the second gasket 138, thereby stabilizing the position of the second gasket 138 in the mounting cavity 135b, which facilitates the positioning of the elastic element 132.

[0077] In some embodiments, the support end 1311 is fused to the guide post 1312.

[0078] Welding is a technique that involves melting materials by heating and then rejoining them to form a single whole.

[0079] In this embodiment, the support end 1311 and the guide post 1312 are fused together, which facilitates the assembly process by first engaging the guide post 1312 with the stroke adjustment mechanism and the elastic element 132, and then connecting the guide post 1312 to the support end 1311, thus increasing assembly convenience. Simultaneously, it also facilitates the provision of a limiting end (such as the limiting end 1313 described below) on the side of the guide post 1312 away from the support end 1311, reducing the likelihood of the guide post 1312 detaching from the mounting cavity 135b, and also limiting the movement of the stroke adjustment mechanism. Of course, the fusion of the support post and the guide post 1312 also increases the overall structural strength of the support member 131, facilitating the formation of a stable support.

[0080] The specific structure of the travel adjustment mechanism is not limited.

[0081] In some embodiments, please refer to Figures 3 to 8 The stroke adjustment mechanism includes a fixed seat 133 and a first adjusting member 134. The fixed seat 133 is connected to the inner panel 12 of the front cover. There is no relative movement between the fixed seat 133 and the inner panel 12 of the front cover. The fixed seat 133 has a hollow space 133a. One end of the first adjusting member 134 passes through the hollow space 133a and is movably connected to the fixed seat 133. The operating end 1341 is located on the side of the first adjusting member 134 away from the fixed seat 133. The first adjusting member 134 can move relative to the fixed seat 133 and the support member 131 under the action of external force. The elastic member 132 is located on the movement path of the first adjusting member 134.

[0082] The fixed seat 133 can serve as a base to provide installation support for the first adjusting member 134. The fixed seat 133 is connected to the inner plate 12 of the front cover and there is no relative movement, which can increase the setting stability of the fixed seat 133, thereby increasing the rigid support stability of the rigid adjusting mechanism 13.

[0083] The hollow space 133a provides space for the first adjusting member 134, the supporting member 131 and the elastic member 132 to facilitate their cooperation.

[0084] The first adjusting member 134 is movably connected to the fixed base 133, so that the first adjusting member 134 can move relative to the fixed base 133, thereby realizing the adjustment of the elastic force of the elastic member 132.

[0085] In this embodiment, the cooperation between the first adjusting member 134 and the fixed seat 133 can achieve a stable cooperation with the inner front cover panel 12, while the movement of the first adjusting member 134 relative to the fixed seat 133 can achieve the movement relative to the support member 131. The movement is simple and reliable and will not affect the inner front cover panel 12.

[0086] The movable connection method between the first adjusting member 134 and the fixed base 133 is not limited.

[0087] In some embodiments, please refer to Figures 3 to 8 The fixed base 133 includes a first threaded section 133b, and the first adjusting member 134 includes a second threaded section 134a. The first threaded section 133b and the second threaded section 134a are threadedly engaged to realize the connection between the first adjusting member 134 and the fixed base 133. The operating end 1341 is used to drive the first adjusting member 134 to rotate so that the first adjusting member 134 has at least a linear displacement along the top and bottom direction during the rotation.

[0088] Specifically, the first threaded segment 133b can be formed on the inner wall of the hollow space 133a.

[0089] In this embodiment, the fixed base 133 and the first adjusting member 134 are movably connected through the cooperation of the first threaded section 133b and the second threaded section 134a. The connection method is simple. When it is necessary to increase the rigid support force on the front cover outer plate 11, it is only necessary to apply external force to the operating end 1341 to rotate the first adjusting member 134 upward, which can gradually increase the rigid support force on the front cover outer plate 11. Furthermore, the cooperation of the first threaded section 133b and the second threaded section 134a can also ensure that the first adjusting member 134 is stably maintained in the adjusted position after movement, increasing the rigid support stability of the front cover outer plate 11. The cooperation method between the fixed base 133 and the first adjusting member 134 is simple, easy to operate, and has good stability.

[0090] It is understandable that the movement displacement of the first adjusting member 134 along the top and bottom direction after one revolution can be adjusted by adjusting the pitch of the first threaded section 133b and the second threaded section 134a.

[0091] In some embodiments, the rotation axis of the first adjusting member 134 is parallel to the top and bottom direction, or the angle between the rotation axis of the first adjusting member 134 and the top and bottom direction is an acute angle.

[0092] That is, the first adjusting member 134 can generate linear displacement along the top and bottom direction by rotation, or it can be inclined relative to the top and bottom direction to generate partial displacement along the top and bottom direction. In this way, the rigid adjusting mechanism 13 can be easily adapted to different installation environments, increasing the adaptability of the rigid adjusting mechanism 13.

[0093] For example, please refer to Figure 3 and Figure 4 The rotation axis E of the first adjusting member 134 is set at an acute angle to the top and bottom directions.

[0094] In some embodiments, please refer to Figures 3 to 8The stroke adjustment mechanism includes a second adjustment member 135. The first adjustment member 134 is open on one side facing the fixed seat 133 to form an open groove 134c. The second adjustment member 135 passes through the hollow space 133a and the open groove 134c to connect with the first adjustment member 134. The second adjustment member 135 is formed as a hollow structure. The space inside the second adjustment member 135 defines at least a portion of the mounting cavity 135b.

[0095] Specifically, the support member 131 passes through the hollow space 133a and the mounting cavity 135b to mate with the second adjusting member 135, and the second adjusting member 135 and the support member 131 can generate relative movement through the support member 131. The elastic member 132 abuts between the second adjusting member 135 and the support end 1311.

[0096] There is no relative movement between the second adjusting member 135 and the first adjusting member 134. That is, the second adjusting member 135 and the first adjusting member 134 are relatively fixed. In this embodiment, the first adjusting member 134 and the second adjusting member 135 can be an integral structure or a separate structure. The second adjusting member 135 is connected to the support member 131 and moves relative to the support member 131 under the drive of the first adjusting member 134, thereby changing the relative position between the second adjusting member 135 and the support end 1311, adjusting the elastic force of the elastic member 132, and ensuring reliable movement.

[0097] In another embodiment, the first adjusting member 134 and the second adjusting member 135 have relative movement.

[0098] In this embodiment, the first adjusting member 134 and the second adjusting member 135 can generate relative movement, that is, the first adjusting member 134 and the second adjusting member 135 are movably connected. In this way, the movement displacement of the stroke adjustment mechanism relative to the support member 131 can be increased or decreased by the movement of the first adjusting member 134 relative to the fixed base 133 and the movement of the second adjusting member 135 relative to the first adjusting member 134, thereby increasing or decreasing the adjustment sensitivity of the rigid adjustment mechanism 13 and adapting to different adjustment requirements.

[0099] In some embodiments, please refer to Figures 3 to 8 The support member 131 includes a limiting end 1313, which is located on the side of the support member 131 away from the front cover outer plate 11. The limiting end 1313 is located outside the mounting cavity 135b and inside the open groove 134c. The limiting end 1313 can be detachably abutted against the end of the second adjusting member 135 away from the front cover outer plate 11 to limit the movement displacement of the first adjusting member 134 in the top and bottom direction.

[0100] In this embodiment, the setting of the limiting end 1313 can restrict the movement of the first adjusting member 134 by abutting against the second adjusting member 135 away from the front cover outer plate 11, so that the movement of the first adjusting member 134 is within a safe and stable range, reducing damage to the elastic member 132 and reducing excessive or insufficient support to the front cover outer plate 11.

[0101] When the first adjusting member 134 is rotated until the second adjusting member 135 abuts against the limiting end 1313, the user will be stopped by the limiting end 1313 if the first adjusting member 134 is rotated in the current direction. The user will be unable to continue rotating in the current direction and can only rotate in the opposite direction.

[0102] In some embodiments, please refer to Figures 3 to 8 The second adjusting member 135 is provided with a limiting structure 1351. The limiting structure 1351 is located on the outside of the open groove 134c. The outer side wall of the second adjusting member 135 protrudes outward to form the limiting structure 1351. The limiting structure 1351 is used to be inseparably connected with the top end of the first adjusting member 134 to limit the movement displacement of the first adjusting member 134 along the top-bottom direction.

[0103] In this embodiment, the limiting structure 1351 can restrict the movement of the first adjusting member 134 by detachably engaging the top end of the first adjusting member 134, so that the movement of the first adjusting member 134 is within a safe and stable range, reducing damage to the elastic member 132 and reducing excessive or insufficient support to the front cover outer plate 11.

[0104] For example, the setting of the limiting structure 1351 can restrict the upward rotation of the first adjusting member 134, and the setting of the limiting end 1313 can restrict the downward rotation of the first adjusting member 134, so that the movement displacement of the first adjusting member 134 is kept within a safe range and can effectively support the front cover outer plate 11, thereby increasing the structural reliability of the rigid adjustment mechanism 13.

[0105] The connection method between the first adjusting member 134 and the second adjusting member 135 is not limited.

[0106] In some embodiments, please refer to Figures 3 to 8 The first adjusting member 134 includes a third threaded section 134b, which is formed in the open groove 134c. The second adjusting member 135 includes a fourth threaded section 135a. The third threaded section 134b and the fourth threaded section 135a are threadedly engaged to achieve the connection between the first adjusting member 134 and the second adjusting member 135.

[0107] Specifically, the first thread segment 133b is an internal thread, the second thread segment 134a is an external thread, the third thread segment 134b is an internal thread, and the fourth thread segment 135a is an external thread.

[0108] In this embodiment, the first adjusting member 134 and the second adjusting member 135 are movably connected through the cooperation of the third threaded section 134b and the fourth threaded section 135a. The connection method is simple. When it is necessary to increase the rigid support force on the front cover outer plate 11, it is only necessary to apply an external force to the operating end 1341 to make the first adjusting member 134 rotate upward, thereby driving the second adjusting member 135 to move. By increasing or decreasing the actual movement displacement of the second adjusting member 135 relative to the support member 131, the support force on the front cover outer plate 11 can be adjusted. In this way, the rigidity adjustment mechanism 13 has stronger adjustability and can increase or decrease the adjustment sensitivity according to the needs.

[0109] In this embodiment, the cooperation of the third threaded section 134b and the fourth threaded section 135a realizes the movable connection between the first adjusting member 134 and the second adjusting member 135. The connection method is simple, easy to operate, and has good stability.

[0110] It is understandable that the movement displacement of the second adjusting member 135 relative to the support member 131 can be adjusted by adjusting the pitch of the second threaded section 134a and the third threaded section 134b after the first adjusting member 134 rotates one revolution.

[0111] In some embodiments, the second threaded section 134a and the third threaded section 134b have opposite thread directions.

[0112] Thus, the first adjusting member 134 and the second adjusting member 135 move in opposite directions, which can reduce the displacement of the second adjusting member 135 relative to the support member 131, making it easier to achieve micro-adjustment of the support force. The stiffness of the front cover outer panel 11 will not change abruptly, increasing the adjustment reliability and the appearance reliability of the front cover outer panel 11.

[0113] In some embodiments, the pitch of the second threaded section 134a is greater than the pitch of the third threaded section 134b. This reduces the adjustment sensitivity of the rigidity adjustment mechanism 13, enabling fine-tuning of the rigidity support force of the front cover outer plate 11 and increasing adjustment reliability.

[0114] For example, the ratio of the pitch of the second threaded section 134a to the pitch of the third threaded section 134b can be 1.5, 2, 2.2, 2.4, 2.5, 2.7, 3, 3.3, 3.5, 4, etc. Taking a pitch ratio of 2 for the second threaded section 134a to the third threaded section 134b as an example, if the first adjusting member 134 rotates one revolution and moves upward by 2mm, the second adjusting member 135 will actually move upward by 1mm.

[0115] In some embodiments, please refer to Figures 3 to 5The outer side wall of the fixing seat 133 is recessed inward to form a snap-fit ​​part 133c. The inner plate of the front cover 12 is provided with a through mounting hole 12a. Part of the fixing seat 133 passes through the mounting hole 12a into the cavity 10a, and the other part snaps with the hole wall of the mounting hole 12a through the snap-fit ​​part 133c and abuts against the bottom wall of the inner plate of the front cover 12.

[0116] In this embodiment, the fixing seat 133 and the inner front cover panel 12 are connected by a snap-fit ​​method. While achieving assembly, it can also avoid the inner front cover panel 12, reduce damage to the inner front cover panel 12, and reduce installation marks on the inner front cover panel 12. At the same time, the connection method is simple and reliable, reducing assembly difficulty.

[0117] For example, the mounting base 133 can be a plastic part.

[0118] In some embodiments, please refer to Figures 3 to 5 The fixing seat 133 has a notch 133d that penetrates the side wall of the hollow space 133a so that the fixing seat 133 can deform when it mates with the mounting hole 12a.

[0119] In this embodiment, the notch 133d allows the fixing seat 133 to retract at least partially inward when it mates with the inner front cover panel 12, in order to accommodate the manufacturing tolerance of the mounting hole 12a of the inner front cover panel 12, thereby increasing the reliability of the mating between the fixing seat 133 and the inner front cover panel 12.

[0120] The following is a brief description of the assembly process of the rigid adjustment mechanism 13 with the inner front cover plate 12 and the outer front cover plate 11 according to an embodiment of this application.

[0121] First, the second adjusting member 135 is fitted onto the outside of the guide post 1312 from top to bottom. The second gasket 138 is fitted with the positioning structure 1352 in the mounting cavity 135b. Then, the elastic member 132 is fitted onto the outside of the guide post 1312. The first gasket 137 is fitted onto the guide post 1312. Finally, the support end 1311 is fused to the guide post 1312. In this way, the second adjusting member 135, the support member 131, and the elastic member 132 form a pre-assembled whole. Then, the first adjusting member 134 is inserted into the hollow space 133a from bottom to top, so that the first threaded section 133b and the second threaded section 134a are threadedly engaged. This makes the first adjusting member 134 and the fixed seat 133 form a pre-assembled whole. Then, the two pre-assembled wholes are fitted together so that the third threaded section 134b and the fourth threaded section 135a are threadedly engaged. In this way, the assembly of the rigid adjusting mechanism 13 is completed.

[0122] Finally, apply adhesive 136 to the glue groove 1311a of the support end 1311, and install the rigid adjustment mechanism 13 into the cavity 10a from bottom to top, so that the snap-fit ​​part 133c of the fixing seat 133 snaps into the mounting hole 12a of the inner front cover plate 12, and the adhesive 136 connects the support end 1311 to the outer front cover plate 11.
