Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle production and assembly, and in particular to a multi-purpose engine hood lock and positioning device. Background Art

[0002] In the field of new energy vehicle production and assembly technology, many parts still require manual assembly. During the assembly process, for ease of operation and good assembly precision, the parts to be assembled often need to be pre-positioned at the installation location before installation. For some parts with positioning structure designs, manual assembly can easily achieve stable assembly quality through the positioning structure of the parts themselves. However, for some parts that are not suitable for positioning structure designs, manual assembly cannot achieve consistent assembly results, thus affecting the assembly precision and efficiency of the parts.

[0003] The inside of a car's hood is fitted with a hood latch. As a manually assembled component, the accuracy and efficiency of its assembly significantly impact the production and assembly process. To assemble the hood latch, the hood must be flipped open to a certain angle before being locked in place on the inside of the hood. The bolts are then tightened manually. Without a high-precision positioning device, the hood latch itself will shift under the force of the bolts during tightening, making it difficult to achieve post-assembly consistency. This results in low hood latch assembly efficiency and a quality risk of excessive clearance between the hood and surrounding parts, making adjustment difficult.

[0004] In the prior art, such as: CN213004953U - a hood lock installation and positioning tool, including a mounting bracket, a locking piece and a positioning frame, the mounting bracket is used to position the positioning tool at the installation position of the lock on the lock mounting beam, the locking piece is used to accurately position and fix the mounting bracket on the lock mounting beam, the locking piece may include a pin seat and a positioning pin, the positioning pin cooperates with the positioning hole on the mounting beam to achieve positioning, the positioning frame is connected to the mounting bracket, and the positioning frame is provided with a limiting space that is compatible with the shape of the hood lock, which is used to limit the posture and position of the hood lock, and the positioning tool may also include a handle. This utility model can realize the installation of the lock in the same posture at a fixed position on the lock mounting beam, improve the installation accuracy of the hood lock, avoid the misalignment of the lock and the lock ring, and improve the stability of the assembly quality. This positioning tool cannot be used on the hood. In addition, this positioning tool can only be adapted to the installation and positioning of the hood lock of the same platform vehicle model, and cannot be shared across different platform vehicles.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] In the description of the present invention, the terms "inside", "outside", "longitudinal", "lateral", "upper", "lower", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0046] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] In view of the technical problems that the hood lock installation and positioning tooling in the prior art cannot be used on the hood and cannot be shared across different platforms, this embodiment provides a multi-purpose hood lock positioning device, such as Figure 1-Figure 4As shown, it includes: an EV positioning support mechanism 1, a PHEV positioning support mechanism 2, a clamping mechanism 3, an adjustable lock positioning mechanism 4 and a base plate 5. The EV positioning support mechanism 1, the PHEV positioning support mechanism 2, the clamping mechanism 3, the adjustable lock positioning mechanism 4 are respectively connected to the base plate 5; in terms of structural setting, the base plate 5 mainly plays a connecting support role, which can provide connecting support for the EV positioning support mechanism 1, the PHEV positioning support mechanism 2, the clamping mechanism 3, the adjustable lock positioning mechanism 4, so that the EV positioning support mechanism 1, the PHEV positioning support mechanism 2, the clamping mechanism 3, the adjustable lock positioning mechanism 4 and the base plate 5 are combined to form a whole. Regarding the ways in which the EV positioning support mechanism 1, the PHEV positioning support mechanism 2, the clamping mechanism 3, the adjustable lock positioning mechanism 4 are respectively connected to the base plate 5, including but not limited to bonding, welding or screwing, screwing is preferred to facilitate detachability during later maintenance.

[0048] The present embodiment provides a multi-purpose engine hood lock positioning device, which can be shared across different platform models, especially EV and PHEV models. Specifically, when applied to EV models, the positioning device can be adjusted to a state suitable for EV models, and when applied to PHEV models, the positioning device can be adjusted to a state suitable for PHEV models. Specifically, during the production and assembly switching process between EV and PHEV models, the EV positioning support mechanism 1 and the PHEV positioning support mechanism 2 are switched synchronously without interference. The EV positioning support mechanism 1 is inserted into a positioning hole preset on the inner side of the engine hood of the EV model, and the positioning device is attached to the engine hood of the EV model with the lock, and the PHEV positioning support mechanism 2 is inserted into a positioning hole preset on the inner side of the engine hood of the PHEV model, and the positioning device is attached to the engine hood of the PHEV model with the lock.

[0049] Since the existing technical solutions can only be adapted to the installation and positioning of the hood locks of vehicles on the same platform, compared with the existing technical solutions, the multi-purpose hood lock positioning device provided in this embodiment can be shared across vehicle platforms, which is equivalent to different vehicle platforms sharing the same set of positioning devices. There is no need to prepare corresponding positioning devices for different vehicle platforms, which can effectively reduce production costs and management costs.

[0050] In order to simplify the manufacturing process of the positioning device and further reduce the production cost, the embodiment provides a multi-purpose engine hood lock positioning device, which adopts a symmetrical design as a whole. Figure 5-Figure 6As shown, the EV positioning support mechanism 1 includes a first EV positioning component 11 and a second EV positioning component 12, and the first EV positioning component 11 and the second EV positioning component 12 are symmetrically arranged about the center plane of the base plate 5; the PHEV positioning support mechanism 2 includes a first PHEV positioning component 21 and a second PHEV positioning component 22, and the first PHEV positioning component 21 and the second PHEV positioning component 22 are symmetrically arranged about the center plane of the base plate 5; wherein, the first PHEV positioning component 21 is on the same side as the first EV positioning component 11, and the second PHEV positioning component 22 is on the same side as the second EV positioning component 12; the clamping mechanism 3 includes a first clamping component 31 and a second clamping component 32, and the first clamping component 31 and the second clamping component 32 are arranged opposite to each other, and the first clamping component 31 and the second clamping component 32 are located on the center plane of the base plate 5; wherein, the first clamping component 31 is clamped at the hollow part inside the EV model engine hood or the PHEV model engine hood, and the second clamping component 32 is clamped at the outer contour part of the EV model engine hood or the PHEV model engine hood.

[0051] By analyzing and studying the hood structures of cross-platform models (including EV models and PHEV models), based on the common structural features and distinctive structural features of the hoods of cross-platform models, and taking into account and utilizing the existing structures of cross-platform models (such as positioning holes, hollow parts, etc.), a multi-purpose hood lock and positioning device provided in this embodiment is obtained.

[0052] The following will describe preferred implementations of the above-mentioned mechanisms and components with reference to the accompanying drawings.

[0053] As one of the preferred implementations, Figure 7As shown, the first EV positioning component 11 includes a first EV positioning column 111, a first connecting block 112 and a first connector 113. The first EV positioning column 111 is axially connected to the first connecting block 112. The first EV positioning column 111 rotates in a first slot 1121 provided on the first connecting block 112. The first connector 113 passes through the first connecting block 112 and fixes the first EV positioning column 111 through a first through hole 1111 provided on the first EV positioning column 111. In this embodiment, a cone head is provided on the top of the first EV positioning column 111. The cone head is determined according to the shape of the positioning hole preset on the inside of the EV vehicle engine hood to ensure that the cone head is tightly matched with the positioning hole preset on the inside of the EV vehicle engine hood. In addition to the axial hole provided at the tail of the first EV positioning column 111, a first through hole 1111 for fixing the first EV positioning column 111 is also provided. A first slot is provided on the first connecting block 112. After 1121, the overall structure is U-shaped, and its two side walls are respectively provided with threaded holes and plug-in holes. The first EV positioning component 11 is fixed to the base plate 5 through the threaded holes, and the first plug-in connector 113 is positioned and stored through the plug-in holes; the first plug-in connector 113 is preferably a simple component similar to a pin, which can be with or without threads. When a technical solution without threads is used, a gravity block can be sleeved on the first plug-in connector 113, which can also prevent the first plug-in connector 113 from falling off. When the first EV positioning column 111 is rotated to the plug-in hole position in the first slot 1121 set on the first connecting block 112 (for example, when the rotation angle of the first EV positioning column 111 is 180°), at this time, the plug-in hole is coaxial with the first through hole 1111. After the first plug-in connector 113 is passed through the first through hole 1111 set on the first EV positioning column 111, the first EV positioning column 111 is fixed.

[0054] As one of the preferred implementations, Figure 8As shown, the first PHEV positioning component 21 includes a first PHEV positioning column 211, a third connecting block 212 and a third plug-in connector 213. The first PHEV positioning column 211 is axially connected to the third connecting block 212. The first PHEV positioning column 211 rotates in a third notch 2121 provided on the third connecting block 212. The third plug-in connector 213 passes through the third connecting block 212 and fixes the first PHEV positioning column 211 through a third through-hole 2111 provided on the first PHEV positioning column 211. In this embodiment, similarly, a cone head is provided on the top of the first PHEV positioning column 211. The cone head is determined according to the shape of the positioning hole preset on the inside of the hood of the PHEV model to ensure that the cone head is tightly matched with the positioning hole preset on the inside of the hood of the PHEV model. In addition to the axial hole provided at the tail of the first PHEV positioning column 211, a third through-hole 2111 for fixing the first PHEV positioning column 211 is also provided. After the third notch 2121 is set, the overall structure is U-shaped, with a threaded hole at the bottom and plug-in holes on the side walls. The first PHEV positioning assembly 21 is fixed to the base plate 5 through the threaded holes, and the third plug-in connector 213 is positioned and stored through the plug-in holes; the third plug-in connector 213 is preferably a simple component similar to a latch, which can be with or without threads. When a technical solution without threads is used, a gravity block can be sleeved on the third plug-in connector 213, which can also prevent the third plug-in connector 213 from falling off. When the first PHEV positioning column 211 is rotated to the plug-in hole position in the third through hole 2111 set on the third connecting block 212 (for example, when the first PHEV positioning column 211 is rotated by 180 degrees), the plug-in hole is coaxial with the third through hole 2111. After the third plug-in connector 213 is passed through the third through hole 2111 set on the first PHEV positioning column 211, the first PHEV positioning column 211 is fixed.

[0055] As one of the preferred implementations, Figure 9As shown, the first clamping assembly 31 includes a pressure rod 311, a transition block 312, a connecting seat 313 and a pressure head 314. The pressure rod 311 and the transition block 312 are respectively connected to the connecting seat 313, and the pressure head 314 is screwed to the transition block 312. The connecting seat 313 is also provided with a threaded hole. The first clamping assembly 31 is fixed to the base plate 5 through the threaded hole. In specific application, the pressure rod 311 is manually operated to realize the transmission of force through the transition block 312, and finally the pressure head 314 is displaced to realize the first clamping assembly 31 A clamping function of a clamping assembly 31; in this embodiment, since the pressure head 314 and the transition block 312 are screwed together, when in use, the pressure head 314 can be rotated clockwise or counterclockwise to pre-adjust the initial position of the pressure head 314; as an improved method, the pressure head 314 can be made of rubber with a certain hardness, or the pressure head 314 can be made by processing a covering of elastic material, which can not only ensure that the pressure applied to the pressure head 314 is sufficient, but also provide an appearance protection for the engine hood.

[0056] As one of the preferred implementations, Figure 10-13 As shown, the adjustable lock positioning mechanism 4 includes a linear guide rail 41, a slider 42, a limit block 43, a lock fork plate 44, a fifth connector 45 and a sixth connector 46. The linear guide rail 41 is arranged in the fifth notch 421 provided on the slider 42, and the slider 42 slides along the linear guide rail 41. The limit blocks 43 are provided at both ends of the linear guide rail 41 to limit the sliding position of the slider 42. The fifth connector 45 passes through the fifth through hole 422 provided on the slider 42 and the linear guide rail 46 in sequence. 1 is used to fix the slider 42; the lock fork plate 44 is axially connected to the slider 42, and the slider 42 is disposed in the sixth notch 441 provided on the lock fork plate 44. The lock fork plate 44 rotates around the slider 42, and the sixth connector 46 sequentially passes through the seventh through hole 442 provided on the lock fork plate 44 and the eighth through hole 423 provided on the slider 42 to fix the lock fork plate 44; wherein, the lock fork plate 44 is also provided with a seventh notch 443 for positioning the lock.

[0057] Considering that there are different models and series of vehicles under the same platform, and the positions of the engine hood locks of different models and series of vehicles have slight variations, in order to further expand the application range of the multi-purpose engine hood lock positioning device provided by this embodiment, such as Figure 11 As shown, the sixth through holes 411 are distributed in a linear array along the sliding direction of the slider 42, and as shown Figure 14As shown, the seventh through-holes 442 are arranged in a circumferential array along the rotational direction of the lock fork plate 44. In this embodiment, the sixth through-holes 411 are arranged in a linear array along the sliding direction of the slider 42, and the fifth connector 45 can be switched to the sixth through-hole 411 at the appropriate position as needed, thereby achieving the adjustment of the horizontal movement position of the positioning device. The seventh through-holes 442 are arranged in a circumferential array along the rotational direction of the lock fork plate 44, and the sixth connector 46 can be switched to the seventh through-hole 442 at the appropriate position as needed, thereby achieving the adjustment of the rotational direction angle of the positioning device, ultimately meeting the assembly requirements of the hood lock of different models and series of vehicles on the same platform. It should be noted that in the process of arraying the sixth through-holes 411 and the seventh through-holes 442, the sixth through-holes 411 and the seventh through-holes 442 can be arrayed to form tooth-like grooves, thereby achieving higher adjustment accuracy within a limited area.

During the assembly of the engine hood lock, the flexible pad 7 will play a buffering and supporting role.
