Description

Technical Field

[0001] The utility model relates to the technical field of VR head-mounted devices, and particularly relates to a VR device for assisting backward walking exercise. Background Art

[0002] Backward walking has certain rehabilitation effects in the rehabilitation field: 1. Enhance core muscle groups and balance ability: When walking backward, more concentration and fine control of the body are required, which helps to enhance core muscle groups and balance ability. 2. Improve posture and gait: Backward walking can change the conventional walking mode and prompt people to pay more attention to body posture and gait. 3. Relieve back and neck pain: When walking backward, the pressure on the spine and neck can be reduced, which helps to relieve back and neck pain. For some people who work sitting for a long time or often feel discomfort in these areas, backward walking may be a beneficial rehabilitation method.

[0003] However, backward walking requires higher balance and coordination. If the balance and coordination are insufficient, it is easy to cause the body to lose control; and when walking backward, the field of vision of people is limited, and they cannot observe the road conditions in the advancing direction through both eyes like when walking forward. Therefore, the perception ability of obstacles or pedestrians behind is reduced, and collisions are likely to occur, resulting in injuries to oneself or others.

[0004] Therefore, based on the lightweight outdoor use scenario and combined with the VR glasses device widely used in the prior art, this solution proposes a VR device that can provide users with a clear view of the field environment behind them during backward walking and enhance the user's perception of the environment behind.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] The present utility model will be further described below with reference to the embodiments.

[0037] Embodiment:

[0038] The present utility model provides a VR device for assisting backward walking exercise. The improvement of this product is mainly used in the daily backward walking exercise of users. This product is optimized and improved on the existing VR all-in-one machine product. The VR body 10 can be well adapted to the user's face through a silica gel mask. Among them, the VR body 10 adopts a high-definition color perspective function. A front camera 11 is provided on the VR body 10. The front camera 11 is used to capture the real-time picture in front of the user, and perform efficient image processing and presentation through the internal GPU chip combined with software algorithms. The basic principles and software and hardware components of the VR body 10 device are existing mature technologies, and will not be elaborated here too much.

[0039] The design core of this application integrally adds a rear lens 40 that can be quickly disassembled and assembled, which is used to display the real-time picture of the environment behind the user when the user is walking backward for exercise, improving the safety of the user's backward walking training. At the same time, the convenient disassembly and assembly maintains the daily use and overall aesthetics of the VR body 10.

[0040] Referring to Figure 1-8 , the improved hardware structure part of this product will be described below:

[0041] This product also includes a flexible headband 20 and a soft headrest 30. The flexible headband 20 and the soft headrest 30 are mainly used to realize the wearing of the VR body 10 on the user's head. Among them, both ends of the flexible headband 20 are fixedly arranged on both sides of the VR body 10, and the soft headrest 30 with a relatively thick memory sponge inside can be slidably arranged on the flexible headband 20. A notch 31 is opened on one side of the soft headrest 30; the notch 31 is a square groove body. By detachably connecting the rear lens 40 to the notch 31, it is used to obtain and capture the real-time picture behind the user, and a quick-connection communication slot 423 is provided on one side.

[0042] Among them, the rear lens 40 includes a camera module 41 and a housing 42, and also includes a PFC flexible board 50 for realizing the communication and interconnection between the camera module 41 and the VR body 10. The PFC flexible board 50 is hiddenly attached inside the flexible headband 20. One side of it is connected to the internal main control board of the VR body 10, and the other side extends into the notch 31 and is welded with copper-clad pins 51. The PFC flexible board 50 is inserted and fixed in the quick-connection communication slot 423 through the copper-clad pins 51 to realize the connection between the rear lens 40 and the main control board. Specifically, a quick-connection communication slot 423 is formed on the housing 42 of the rear lens 40, and the connection pins 411 of the camera module 41 are exposed at the quick-connection communication slot 423. When the copper-clad pins 51 are inserted into the quick-connection communication slot 423, they are connected to the connection pins 411 one by one. Specifically, in this embodiment, according to the requirements of the product, the camera module 41 is welded and led out with 4 pins, namely a power supply pin, a signal pin, a control pin, and a status indication pin, which can also be used to support specific functions or operations.

[0043] Based on the existing VR devices, this product is equipped with a rear lens 40 that can be quickly disassembled and assembled to capture real-time images of the user's back. At the same time, the communication and quick disassembly / assembly functions of the rear lens 40 are realized through the PFC flexible board 50 and the soft headrest 30 respectively. When the user needs to perform backward walking exercises outdoors, the rear lens 40 can be easily installed. Through the display of the images captured by the rear lens 40 on the VR body 10, the user can clearly observe the surrounding environment behind, timely grasp the spatial status of obstacles or pedestrians behind, enhance the user's perception of the environment behind, and greatly reduce the risk of injury. At the same time, in a normal indoor scenario, the rear lens 40 can be disassembled to keep the VR body 10 simple and ensure its normal application, better meeting the daily use needs of users.

[0044] The following will illustrate the quick disassembly and assembly of the rear lens 40 of this product through the optimal embodiment:

[0045] First, the flexible headband 20 is designed as a double-layer structure with a cavity 21 formed inside. A notch 22 is provided in the cavity 21 near the middle of the flexible headband 20, which enables the PFC flexible board 50 to be attached inside the cavity 21, and the side with the copper-clad pins 51 passes through the notch 22 for convenient connection with the rear lens 40.

[0046] In terms of the disassembly and assembly of the rear lens 40, in this embodiment, a fixed connection form using Velcro combination is selected. Specifically, a first through groove 32 and a second through groove 33 that are perpendicularly distributed are provided on the plane of the soft headrest 30 parallel to the notch 31. The soft headrest 30 is slidably arranged on the flexible headband 20 through the first through groove 32, and the notch 31 communicates with the first through groove 32 and the second through groove 33 respectively.

[0047] On the same side of the second through groove 33 and the notch 31, a first Velcro hook surface 34 is provided, and a first Velcro loop surface 35 is provided on the other side. A second Velcro loop surface 23 is provided on the middle part of the flexible headband 20. In addition, a second Velcro hook surface 43 is fixed on one side of the outer shell 42. The outer shell 42 can pass through the notch 31 and is fixed by connecting the second Velcro hook surface 43 with the first Velcro loop surface 35 and the second Velcro loop surface 23 respectively, thereby realizing the stable fixation among the rear lens 40, the flexible headband 20, and the soft headrest 30.

[0048] Among them, the fixing method of the Velcro among the three and the distribution positions of the fuzzy surface and the hook surface can not only facilitate the stable fixing, disassembly and assembly at the rear, but also maintain the aesthetic appearance of the product when the rear camera 40 is removed. By using the fixing form between the Velcros, it is not only convenient for the disassembly and assembly of the rear camera 40, but also, due to the product characteristics of the Velcro itself, it will increase the stiffness of the bonding surface material, that is, it can maintain the stable connection of the rear camera 40 against shake and loosening, and will not cause discomfort at the head wearing part here.

[0049] In addition, preferably in this embodiment, it is designed that the projection plane of the second through groove 33 includes the notch 31, that is, the planar area of the second through groove 33 is larger than the opening of the notch 31. Such a design is convenient for users to operate when disassembling and assembling the rear camera 40. At the same time, the larger inner space can hide and place the heads of the copper-clad pins 51 of the PFC flexible board 50 led out.

[0050] In addition, preferably in this embodiment, a plastic ring 36 is fixed around the notch 31. The plastic ring 36 is made of elastic plastic material and is tightly fixed at the notch 31 by a hot press. On the one hand, the design of the plastic ring 36 realizes the edge locking of the notch 31, improving the durability and aesthetic appearance of the product. At the same time, by providing a strip groove 421 on the side of the outer shell 42 that cooperates with the plastic ring 36 for snap connection, the fixing stability of the rear camera 40 can be improved.

[0051] Among them, preferably, on the side of the outer shell 42 where the second Velcro hook surface 43 is provided, there is an outwardly extending connecting plate 422. The inner side of the connecting plate 422 is a hollow structure. The hollow structure enables the first Velcro hook surface 34 and the first Velcro fuzzy surface 35 of the second through groove 33 to complete adhesion through the hollow area of the connecting plate 422, improving the connection stability. The design of the upwardly extending connecting plate 422 increases the contact surface for fixing the outer shell 42, and can effectively prevent the rear camera 40 from dropping or tilting downward due to its own weight, affecting image acquisition.

[0052] In the design of realizing the quick connection between one end of the copper-clad pin 51 of the PFC flexible board 50 and the rear camera 40, an elastic limiting structure 60 is provided at the bottom of the connection pin 411 inside the outer shell 42. The elastic limiting structure 60 includes a top plate 61. An open limiting groove 63 is formed on the upper side of the top plate 61, and the limiting groove 63 is aligned with the quick connection communication slot 423. Its bottom is connected to the inner wall of the outer shell 42 by a spring 62. The copper-clad pin 51 can be inserted into the limiting groove 63 in cooperation, and the copper-clad pin 51 is pressed tightly on the connection pin 411 by the restoring force of the spring 62. Among them, the top plate 61 is provided with a chamfer at the opening of the limiting groove 63. During installation, the end of the hard copper-clad pin 51 can be directly inserted. During disassembly, it can be directly pulled out, which is convenient for operation.

[0053] Optionally, the number of the rear cameras 40 may also be two, that is, it includes two sets of rear cameras 40 for imaging. Other components of the second set may be set with reference to the first set, which will not be elaborated here, so as to form binocular stereo imaging. Images collected by the binocular cameras are respectively sent into the left and right glasses of the VR body to obtain a stereo effect.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
