In other embodiments, such a headset may be used for wireless data communication, and thus, a cable in a physical sense may not be provided, and the present invention is still applicable, which will be described in more detail in the following detailed description of the present invention.
[ first embodiment ] A method for manufacturing a semiconductor device
The first embodiment of the present invention is exemplified by a head-mounted device having a cable interface and at least one bundle of cables 70 physically connected to the cable interface, such as the devices shown in fig. 1 and 2.
As shown in fig. 2 and 3, the integrated safeguard system as an alternative embodiment has a first telescopic terminal block 10, the first telescopic terminal block 10 having a first box body 11 and a first rope 12 that can be pulled out and retracted from an outlet of the first box body; the first rope 11 is preferably a steel rope to facilitate a certain tensile strength and toughness.
The free end (i.e., lower end in fig. 2) portion of the first cord 12 is configured to be fixedly connected to the headset housing 80 and/or headband 90. A headband 90, which generally extends from the front to the rear of the head-mounted device along the centerline, is used to partially encircle and secure the head with the synchronization of the user.
With reference to fig. 2, the aforementioned free ends preferably form a secure connection by being secured to the headband 90 in a pyramid-like configuration 40.
In connection with fig. 2, in an embodiment of the invention, the first rope 12 is arranged offset from the at least one bundle of cables 70 without touching it, so that in any case no tension is exerted on the cables 70 from the user or the weight of the device, thus avoiding possible damage.
Referring to fig. 2, the integrated safety and security system of the present embodiment further includes a buffer mechanism 20 disposed along the first rope 12, the buffer mechanism 20 having a first end 21 coupled to the first rope 11 at a first position a, a second end 21 coupled to the second rope at a second position B, and an elastic mechanism 23 disposed between the first end and the second end, the elastic mechanism 23 being configured to satisfy: in the freely suspended state of the head mount 60, the portion of the rope 12C between the first end and the second end is not subjected to a tensile force (i.e., a tensile force from the weight of the head mount), but is subjected to a tensile force from the weight of the head mount by the elastic mechanism.
With reference to fig. 2, the first rope 11 preferably has a first section 11A from the wire coil inside the first casing to a first position a outside the outlet, a portion of the rope 12C arranged between the first and second ends and a second section 11B from the second position B to the free end. In other embodiments, the three pieces of rope may be provided independently without forming an integral body.
Therefore, as shown in fig. 2, with such a design, in a state where the head-mounted device is naturally suspended, only the tensile force is applied to the elastic mechanism, but not directly applied to the steel wire rope (first rope), when the head-mounted device is moved, the tensile force from the user and the head-mounted device is first applied to the buffer mechanism, and then applied to the wire coil of the first rope after buffering, so that the overall stretching operation of the first rope is performed, thereby avoiding that the head-mounted device 60 is directly stretched after being pulled, and the bad experience of pulling the head is generated by directly pulling out the rope from the steel wire coil.
As shown in fig. 1, the elastic mechanism 23 is preferably one of an elastic string or an elastic spiral string, which has a certain elastic force. Preferably, the elastic means 23 has a length, in the first state, under tension from the weight of the head-mounted device, which is smaller than the length of the portion of the cord 12C located between the first end 21 and the second end 22.
As shown in fig. 2, when the elastic mechanism 23 is in the first state, a portion of the rope between the first end and the second end is in a free state, i.e., is not tensioned or straightened by the tension from the weight of the head-mounted device.
As shown in connection with fig. 2, the damping mechanism 20 is further configured to have a second state in which the elastic mechanism may be stretched and a third state in response to a pulling force originating from the headset 60. That is, in the second state, when the user wears the head set 60 and moves so that the head set 60 needs to move away from the first retractable pull-string box 10, the user directly acts on the elastic mechanism 23, for example, the elastic cord shown in fig. 2, and stretches the elastic cord until the elastic cord has a length equal to that of the aforementioned partial cord 12C, and then the user enters the third state because the second segment 12B, the partial cord 12C, and the elastic cord 23 are located at one connection point at this point, that is, the second position B, and the elastic cord 23 cannot be further stretched due to the length restriction of the partial cord 12C.
In the third state, the elastic mechanism 23 is stretched to the same length as the length of the part of the rope 12C between the first end and the second end, and the elastic mechanism 23 and the part of the rope 12C jointly bear the tension from the head-mounted equipment to cause the overall telescopic movement of the first rope, namely, the tension generated by the movement applied by the user causes the overall stretching movement of the first rope 12 from the wire coil in the first box body.
Referring to fig. 2, the first end 21 and the second end 22 are fixedly connected to corresponding positions on the first rope.
As previously described, the second segment 12B, the portion of the cord 12C, and the elastic cord 23 are at one connection point at the second location B. The first section 12A, the partial cord 12C, and the elastic cord 23 are at one connection point at a first location a.
With reference to fig. 2 and 3, preferably, the first end 21 and the second end 22 are of the same buckle structure, and have a fixing portion 21A fixed to the first rope and a turning portion 21B connected to the rotatable fixing portion, the turning portion 21B has a flat plate-shaped main body and ear portions located at two sides of the main body, and the fixing portion 21 is disposed between the two ear portions by a pin structure 21C, so that the turning portion can be turned along the extending direction of the first rope along the rotation axis defined by the pin. Therefore, the smoothness of movement of the whole suspension guarantee system in different directions is facilitated, and winding and rigid rotation or movement switching are avoided.
With reference to fig. 2 and 3, elastic cords are provided connected between the respective turns of the first and second ends 21, 22.
As shown in fig. 3, the turned part 21B has holes, and both ends of the elastic means are configured to be connected to the corresponding holes or to be fastened into the holes by a rotatable locker 21D.
[ second embodiment ]
In a second embodiment of the present invention, the entire suspension integrated guarantee system further includes:
a second retractable terminal block 30 having a second box body 31 and a second cord 32 that can be pulled out and retracted from an outlet of the second box body 31; the free end of the second tensile cord 32 is arranged to connect with the at least one bundle of cables and to restrain the holding state between it and the free end of the second cord.
As shown in fig. 2, in the case of the second telescopic terminal block 30, it can be fixed to a wall (preferably a ceiling) separately from the first telescopic terminal block 10, so that the primary suspension guarantee by the first telescopic terminal block 10 is achieved, the primary protection of the head-mounted device 60 and the cables is achieved, and the secondary suspension guarantee by the second telescopic terminal block 30 is achieved, the secondary protection of the cable extension is achieved.
[ third embodiment ]
In a third embodiment of the invention, the whole suspension integrated guarantee system aims at realizing the suspension protection of the cordless head-mounted equipment, and the equipment is not equipped with a data harness cable any more and carries out data transmission in a wireless mode. Thus, there is no secondary suspension guarantee, i.e. no second telescopic terminal box, and on the basis of the first embodiment, the same design structure is used, and the positions of the first rope and the cable are not limited.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
