Description

Technical Field

[0001] The utility model relates to the technical field of dummies, in particular to an H-point dummy suitable for non-contact measurement. Background Technique

[0002] The driver's H-point is regarded as one of the key reference points for the position of the occupant, the configuration of the seat facilities, the interior space of the vehicle, and the positioning of the collision test. The SAE's H-point measurement dummy (HPM) is a three-dimensional dummy model. After it is placed in the vehicle, it can provide the physical space dimensions of this reference point. The HPM can not only determine the position of the H-point, but also measure the internal space scale.

[0003] During the use of the existing H-point dummies, although they can measure the vehicle, they cannot adjust the legs of the dummies, resulting in tilting or moving during the detection process, leading to inaccurate detection results. At the same time, they cannot add weights according to users of different body types, resulting in discomfort for different people during driving, thus reducing the adjustability and clamping fixation of traditional H-point dummies. Therefore, an H-point dummy suitable for non-contact measurement is introduced. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an H-point dummy suitable for non-contact measurement, which has the advantages of strong adjustability and clamping fixation, and solves the problems raised in the above background technique.

[0005] The utility model provides the following technical solution: an H-point dummy suitable for non-contact measurement, including legs. A torso is provided at the top of the legs. A placement groove is opened on the inner wall of the torso. A moving groove is opened on the inner wall of the placement groove. An adjusting component is provided on the inner wall of the placement groove. A counterweight block is placed on the top of the torso. A fixing rod is fixedly assembled at the top of the legs. Rotating plates are rotatably connected to the inner walls on both sides of the fixing rod. A second toothed block is fixedly assembled on the outer wall of the rotating plate.

[0006] As a preferred technical solution of the utility model: One end of a second spring is fixedly assembled on the inner wall of the rotating plate. The other end of the second spring is fixedly assembled with a clamping plate. A first toothed block is fixedly assembled on the outer wall of the fixing rod. One end of a first spring is fixedly assembled on the inner wall of the fixing rod. The other end of the first spring is fixedly assembled with a clamping block.

[0007] As a preferred technical solution of the utility model: The adjusting component includes a rotating block. A rotating rod is fixedly assembled at the bottom of the rotating block. A gear is fixedly assembled at the bottom of the rotating rod. A rack is provided on the outer wall of the gear. A limiting rod is fixedly assembled at the bottom of the rack.

[0008] As a preferred technical solution of the present utility model: The gear meshes with the rack for transmission. Both the rack and the limiting rod are slidably connected to the inner wall of the moving groove, and the leg is fixedly assembled with the bottom of the limiting rod.

[0009] As a preferred technical solution of the present utility model: The rotating rod is rotatably connected to the inner wall of the trunk, and the clamping block is adapted to the inner wall of the fixed rod.

[0010] As a preferred technical solution of the present utility model: There are two sets of the adjusting components, and the two sets of adjusting components are respectively located on the inner wall of the placing groove.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. For the H-point dummy applicable to non-contact measurement, when the H-point dummy is placed in the driver's seat, by the staff rotating the rotating block, the rotating block drives the rotating rod and the gear to rotate during the rotation process. Through the meshing transmission between the gear and the rack, the gear drives the rack to move on the inner wall of the moving groove during the rotation process. During the movement of the rack, it drives the limiting rod and the leg to move, so that the leg fits on the surface of the device, thereby realizing the adjustment of the leg of the H-point dummy and preventing the H-point dummy from shifting during the test.

[0013] 2. For the H-point dummy applicable to non-contact measurement, when weighing the H-point dummy, by the staff rotating the rotating plate, the rotating plate rotates inside the fixed rod. When the staff puts the counterweight block on the top of the trunk, the staff rotates the rotating plate again, so that the tooth-shaped block II on the outer wall of the rotating plate and the tooth-shaped block I on the outer wall of the fixed rod are staggered and fitted, thereby realizing the limit fixation of the fixed rod and the rotating plate and facilitating the placement of the counterweight block. By the staff pulling the clamping block and the clamping plate, the clamping block and the clamping plate move inside the fixed rod and the rotating plate respectively, and the height of the clamping block and the clamping plate is adjusted according to the height of the counterweight block. After adjusting the height, the staff releases the hand, and the elastic potential energy of the first spring and the second spring is released, so that the first spring and the second spring drive the clamping block and the clamping plate to clamp the counterweight block, thereby realizing the clamping fixation of the counterweight block and preventing the counterweight block from falling off during the work and damaging the inner wall of the product.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 - Figure 6 , a hip point dummy applicable to non-contact measurement, including an outrigger 1, a trunk 2 is provided at the top of the outrigger 1, a placing groove 13 is opened on the inner wall of the trunk 2, a moving groove 14 is opened on the inner wall of the placing groove 13, an adjusting assembly 3 is provided on the inner wall of the placing groove 13, a counterweight 5 is placed on the top of the trunk 2, a fixed rod 4 is fixedly assembled at the top of the outrigger 1, rotating plates 6 are rotatably connected to the inner walls on both sides of the fixed rod 4, and a second toothed block 8 is fixedly assembled on the outer wall of the rotating plate 6.

[0024] In the above structure, when counterweighting the hip point dummy, after the staff rotates the rotating plate 6 to rotate along the fixed rod 4 on the inner wall, subsequently, when the staff places the counterweight 5 on the top of the trunk 2, the rotating plate 6 is rotated again to ensure that the second toothed block 8 on the outer wall of the rotating plate 6 intersects and tightly fits with the first toothed block 7 on the outer wall of the fixed rod 4. This process aims to achieve stable limiting of the fixed rod 4 and the rotating plate 6, so as to facilitate accurate placement of the counterweight 5 on this basis.

[0025] In a preferred embodiment: One end of a second spring 11 is fixedly assembled to the inner wall of the rotating plate 6, and the other end of the second spring 11 is fixedly assembled to a clamping plate 12. One end of a first spring 9 is fixedly assembled to the outer wall of the fixed rod 4, and the other end of the first spring 9 is fixedly assembled to a clamping block 10.

[0026] In the above structure, by the staff pulling the clamping block 10 and the clamping plate 12, it is ensured that the clamping block 10 and the clamping plate 12 move precisely within the range of the inner walls indicated by the fixed rod 4 and the rotating plate 6. Based on the current height of the counterweight 5, the heights of the clamping block 10 and the clamping plate 12 are adjusted accordingly. Once the height is adjusted to the appropriate position, the staff needs to ensure that the operating component is safely released. Subsequently, the elastic potential energy stored in the first spring 9 and the second spring 11 is released, prompting them to drive the clamping block 10 and the clamping plate 12 to clamp the counterweight 5. This clamping process aims to ensure that the counterweight 5 remains stable during operation, prevent it from falling off, and thus avoid potential damage to the inner wall of the product.

[0027] In a preferred embodiment: The adjusting assembly 3 includes a rotating block 301. A rotating rod 302 is fixedly assembled to the bottom of the rotating block 301. A gear 303 is fixedly assembled to the bottom of the rotating rod 302. A rack 304 is provided on the outer wall of the gear 303. A limiting rod 305 is fixedly assembled to the bottom of the rack 304.

[0028] In the above structure, when placing the H-point dummy in the driver's seat position, the staff needs to operate the rotating block 301 to ensure that it synchronously drives the rotating rod 302 and the gear 303 to rotate during the rotation process. Through the meshing transmission mechanism between the gear 303 and the rack 304, the rotation of the gear 303 will drive the rack 304 to move precisely within the inner wall of the moving groove 14. At the same time, the movement of the rack 304 will drive the limiting rod 305 and the leg 1 to be adjusted accordingly, ensuring that the leg 1 is in close contact with the surface of the device, achieving precise adjustment of the leg 1 of the H-point dummy, preventing the H-point dummy from shifting during the test, and ensuring the accuracy and reliability of the test.

[0029] In a preferred embodiment: The gear 303 meshes with the rack 304 for transmission. Both the rack 304 and the limiting rod 305 are slidably connected to the inner wall of the moving groove 14. The leg 1 is fixedly assembled to the bottom of the limiting rod 305.

[0030] In the above structure, during the rotation of the gear 303, it will drive the rack 304 to move in a limited manner within the inner wall of the moving groove 14, and during the movement of the limiting rod 305, it will drive the leg 1 to move.

[0031] In a preferred embodiment: The rotating rod 302 is rotatably connected to the inner wall of the torso 2, and the clamping block 10 is adapted to the inner wall of the fixed rod 4.

[0032] In the above structure, when the rotating rod 302 rotates on the inner wall of the torso 2, the parts on the inner wall of the torso 2 will not be damaged, and the clamping block 10 will not get stuck during the moving process.

[0033] In a preferred embodiment: there are two sets of adjusting components 3, and the two sets of adjusting components 3 are respectively located on the inner wall of the placement groove 13.

[0034] In the above structure, the two sets of adjusting components 3 are used to adjust the two legs 1 to prevent the situation of tilting when only one set is adjusted.

[0035] Working principle: When placing the H-point dummy in the driver's seat, the staff needs to operate the rotating block 301. During its rotation process, the rotating rod 302 and the gear 303 are driven to rotate synchronously. Through the precise meshing transmission between the gear 303 and the rack 304, the gear 303 can guide the rack 304 to move stably on the inner wall of the moving groove 14 when rotating. At the same time, the movement will also cause the limiting rod 305 and the leg 1 components associated with the rack 304 to move synchronously, ensuring that the leg 1 is in close contact with the surface of the device, so as to achieve precise adjustment of the key parts of the H-point dummy, effectively avoiding the deviation of the H-point dummy during the test. For the counterweight process of the H-point dummy, the staff needs to first operate the rotating plate 6 to rotate it on the inner wall of the fixed rod 4, place the counterweight block 5 on the top of the torso 2, and then operate the rotating plate 6 again to ensure that the tooth-shaped block two 8 on the outer wall of the rotating plate 6 is staggered and fitted with the tooth-shaped block one 7 on the outer wall of the fixed rod 4, realizing the limit fixation of the fixed rod 4 and the rotating plate 6, providing a stable foundation for the placement of the counterweight block 5. The staff needs to pull the clamping block 10 and the clamping plate 12 to move them in the inner walls of the fixed rod 4 and the rotating plate 6, adjust the corresponding positions of the clamping block 10 and the clamping plate 12 according to the height of the counterweight block 5. After the height adjustment is completed, release them. At this time, the elastic potential energy of the first spring 9 and the second spring 11 will be released, driving the clamping block 10 and the clamping plate 12 to clamp and fix the counterweight block 5, ensuring that the counterweight block 5 is stable and does not fall off during the working process, thereby protecting the inner wall of the product from damage.
