Description

Technical Field

[0001] The invention relates to a radar backpack, in particular to a radar backpack with a flexible circuit board. Background Art

[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), direction, altitude, etc.

[0003] Flexible circuit board is a kind of highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bending performance.

[0004] For the safety of travelers in outdoor adventures, radars are now installed on backpacks, which not only makes it easier for travelers to find directions and detect other creatures, but also makes it easier for search and rescue teams to locate travelers when encountering dangerous situations. However, the existing technology often uses PCB boards to make circuits that drive radars. More PCB boards not only easily increase the overall weight of the backpack, but also the circuit boards installed in the backpack are difficult to remove when cleaning the backpack, and direct cleaning can easily cause water to enter the circuit boards. Summary of the invention

[0005] The present invention provides a radar backpack with a flexible circuit board, which can effectively solve the above problems.

[0006] The present invention is achieved in that:

[0007] A radar backpack with a flexible circuit board comprises: a bag body for carrying items, a rear bag sewn to one side of the bag body, and a shoulder strap sleeved on an end of the rear bag away from the bag body;

[0008] The shoulder strap includes an adjustment plate and a soft belt buckled on the adjustment plate, and a ring is arranged at a position of the soft belt close to the top of the backpack, and the ring is sleeved with the rear bag and makes the shoulder strap detachable;

[0009] The soft belt includes an inner pad that fits the human shoulder, a flexible circuit board is glued to the side of the inner pad away from the rear bag, a solar panel is arranged at one end of the flexible circuit board away from the inner pad and close to the adjustment sheet, and an outer pad is connected to the side of the solar panel away from the adjustment sheet.

[0010] As a further improvement, the rear bladder bag includes a bag body sewn together with a bag body, and a flexible battery plate buckled inside the bag body. Two sleeve columns connected to the sleeve ring are arranged on the top of the bag body close to the human body.

[0011] As a further improvement, the sleeve ring includes a cylinder sleeved on the outside of the sleeve column, a buckle rope glued to one side of the cylinder, and a clamp head fixed to the buckle rope.

[0012] As a further improvement, a glue sealing area and a locking cavity which are fixedly locked with the clamping head are provided on the inner side of the sleeve.

[0013] As a further improvement, the soft belt is provided with two, and the soft belt close to the left hand side of the human body is plugged with a radar screen. The radar screen includes an inner groove opened in the lower half of the soft belt, and two slot holes are opened on the inner side of the inner groove. Two retractable ropes are connected to the slot holes to connect with the display screen.

[0014] As a further improvement, the flexible circuit board includes an emitter, a transmitting antenna, a receiving electrode, a receiving antenna, and an FPC core processor. The emitter, the transmitting antenna, the receiving electrode, and the receiving antenna are all electrically connected to the FPC core processor, and the receiving antenna is electrically connected to the display screen.

[0015] As a further improvement, the electrical components in the transmitting antenna and the receiving antenna are all made of flexible circuit board materials.

[0016] As a further improvement, the thinner part of the flexible circuit board close to the human shoulder is the connection circuit part, and the thicker part away from the human shoulder is the component installation part.

[0017] As a further improvement, the adjustment sheet is a colloid belt structure, and penetrates through a portion of the rear bag and is buckled with the bag body.

[0018] As a further improvement, a transceiver switch is provided between the transmitter and the receiver.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention replaces the traditional PCB board with a flexible circuit board, and uses an antenna made of flexible circuit board material, which is fixed on the flexible circuit board, thereby reducing the overall weight and volume of the radar control circuit. The flexible circuit board is installed on the shoulder strap position of the backpack and does not occupy the usable space in the backpack, thereby improving portability and expanding the space that the backpack can carry items.

[0021] 2. The present invention uses a flexible circuit board to not only separate the transmitter and receiver of the radar, but also install the transmitter and the component part on the lower part of the strap, and install the connecting parts on both sides on the upper part of the strap, so as to disperse the components and prevent them from piling up in one place to cause bloat and unsightly appearance, and also prevent the components set at the folding part of the strap from being frequently folded and squeezed to affect the use effect of the radar.

[0022] 3. The present invention uses the cooperation between the sleeve ring and the sleeve column to lock the sleeve column when in use. The threaded locking method is adopted. Compared with the traditional sewing of cloth products, it can provide better tear resistance and buffering force for tourists' running, rushing, pulling and other actions during travel. When the backpack needs to be washed, the entire shoulder strap can be removed by the elastic sleeve head to wash the bag body, and there is no need for too many cumbersome disassembly processes when washing.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0041] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0042] Reference Figure 1-Figure 10 As shown, a radar backpack with a flexible circuit board comprises: a bag body 0 for carrying items, a rear bag 1 sewn to one side of the bag body 0, and a shoulder strap 2 sleeved on an end of the rear bag 1 away from the bag body 0;

[0043] The shoulder strap 2 includes an adjustment plate 20 and a soft belt 21 buckled on the adjustment plate 20. The soft belt 21 is provided with a ring 22 near the top of the backpack. The ring 22 is sleeved with the rear bag 1 and makes the shoulder strap 2 detachable.

[0044] Specifically, the soft belt 21 includes an inner pad 210 that fits the human shoulder, and a flexible circuit board 211 is glued to the side of the inner pad 210 away from the rear bag 1, and a solar panel 213 is provided at one end of the flexible circuit board 211 away from the inner pad 210 and close to the adjusting piece 20, and an outer pad 212 is connected to the side of the solar panel 213 away from the adjusting piece 20. The inner pad 210 can ensure that the backpack will not cause too much burden on the human body's muscles when it is in contact with the human body, and the burden on the muscles is still small even after carrying it for a long time. The solar panel 213 can absorb a little more electricity when walking during the day to improve the endurance. The outer pad 212 is installed at the position where the shoulder strap 2 contacts and bends with the human shoulder. A relatively soft gasket is set at this position, which can not only prevent the circuit board here from being subjected to too much bending force to cause irreparable deformation or damage, but also improve the softness from the outside, so that the inner pad 210 inside and the outer pad 212 outside both have a pressure-relieving effect on the shoulders, thereby relieving the pressure caused by the backpack on the shoulders.

[0045] Furthermore, the rear bag 1 includes a bag body 13 sewn together with the bag body 0, and a flexible battery plate 12 snapped into the bag body 13. Two sleeves 11 connected with the sleeve ring 22 are arranged on the top of the bag body 13 on the side close to the human body. The flexible battery plate 12 can be taken out from the bag body 13 when cleaning. The interior is connected by a snap buckle, which makes it relatively simple to remove and install.

[0046] Furthermore, the ring 22 includes a cylinder 222 sleeved on the outside of the sleeve 11, a buckle rope 221 glued to one side of the cylinder 222, and a clamp 220 fixed to the buckle rope 221. The buckle rope 221 can fix the clamp 220 to prevent the clamp 220 from being lost after being loosened. There is a layer of rubber ring inside the cylinder 222, which can not only improve the overall waterproofness, but also reduce the friction between the sleeve 11 to prevent the backpack from moving too much and causing greater wear when running fast.

[0047] Furthermore, a glue sealing area and a locking cavity which are fixedly locked with the clamp 220 are provided on the inner side of the sleeve 11. After the thread of the locking cavity of the sleeve 11 is fully matched with the stud of the clamp 220, the nut of the clamp 220 can transitionally match with the glue sealing area, and the sleeve 11 and the collar 22 form a cylindrical structure, which is more beautiful and natural.

[0048] Furthermore, the soft belt 21 is provided with two, and the soft belt 21 close to the left hand side of the human body is plugged with a radar screen 23, and the radar screen 23 includes an inner groove 232 opened in the lower half of the soft belt 21, and two slots 231 are opened on the inner side of the inner groove 232. The slots 231 are connected with two retractable ropes and connected to the display screen 230. The radar screen 23 is fixed in the shoulder strap 2 on the left hand side. It can be pulled out for viewing when in use, and can be automatically pulled back to its original position when not in use, which is convenient for the user to use and reset.

[0049] Furthermore, the flexible circuit board 211 includes an emitter, a transmitting antenna, a receiving electrode, a receiving antenna, and an FPC core processor. The emitter, the transmitting antenna, the receiving electrode, and the receiving antenna are all electrically connected to the FPC core processor, and the receiving antenna is electrically connected to the display screen 230.

[0050] Furthermore, the electrical components in the transmitting antenna and the receiving antenna are all made of flexible circuit board materials. The circuit materials inside the antenna are replaced with flexible circuit board materials to reduce the overall weight, reduce the weight of the backpack, make it more portable, and save travelers' physical strength.

[0051] Furthermore, the thinner part of the flexible circuit board 211 close to the human shoulder is the connection circuit part, and the thicker part away from the human shoulder is the component installation part. The folded part is the connection circuit and is thinner, which reduces the stress on the shoulder and reduces the wear and tear on the user's shoulder.

[0052] Furthermore, the adjustment sheet 20 is a colloid belt structure, and is buckled with a part of the rear bag 1 through the rear bag 1 and the bag body 0. The colloid structure is less likely to be torn than the original cloth structure, and is fixed in the rear bag 1 and the bag body 0. Unless the backpack is torn as a whole, the backpack will not be disconnected from the bottom.

[0053] Furthermore, a transceiver switch is provided between the transmitter and the receiver, which can enable only the transmitting function or the receiving function and disable the other function when energy is insufficient, thereby saving more power.

[0054] Furthermore, both the transmitting antenna and the receiving antenna use coated paper as the substrate, and the conductive silver paste is printed with ink. The antenna size is 10*70mm, the substrate thickness is 85μm, the ink thickness is 10μm, and the resistance is 10Ω. Coated paper can also be used as the substrate, and copper oxide paste is printed with ink. The antenna size is 14*68mm, the substrate thickness is 70μm, the ink thickness is 8μm, and the antenna resistance is 10.5Ω.

[0055] The use principle of the present invention:

[0056] When the user needs to use the backpack, the cylinder 222 is put on the sleeve column 11, and the clamp head 220 is meshed with the sleeve column 11, so that the two straps 2 are fixed on the rear bag 1, and then the flexible battery board 12 is put into the bag body 13, so that the flexible battery board 12 and the flexible circuit board 211 in the strap 2 are electrically connected to provide power for the start of the radar, and then the adjustment piece 20 is buckled with the bottom of the soft belt 21;

[0057] After the user puts on the backpack, the inner pad 210 contacts the shoulders of the user, and the cotton effect of the outer pad 212 facilitates the folding of the shoulders. When the surrounding environment needs to be detected, the emitter and the transmitting antenna in the flexible circuit board 211 emit electromagnetic waves to scan the surrounding environment. The electromagnetic wave signals fed back are received by the receiving antenna, transmitted to the receiving electrode, and then transmitted to the display screen 230. People can pull the display screen 230 in front of them to observe and monitor the information of the surrounding environment.

[0058] After use, the clamp 220 can be unscrewed to separate the cylinder 222 from the sleeve 11, and then the connection position between the soft belt 21 and the adjusting plate 20 can be opened, and the soft belt 21 can be removed for dry cleaning, and then the flexible battery board 12 in the rear bag 1 can be taken out, and the bag body 0 and the rear bag 1 can be washed with water, which makes cleaning more convenient and can be cleaned more thoroughly.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
