Description

Technical Field

[0001] The present application relates to the field of commercial vehicle parts, and in particular to an active protection sleeper berth. Background Art

[0002] Currently, the berths of commercial vehicles are generally used for drivers and passengers to lie down and rest. However, there are many cases where there are passengers sitting or standing on the berth. If the vehicle encounters sudden braking or an accident during driving, the passengers on the berth have no appropriate protection measures and may be thrown out, which may endanger their lives. Currently, some heavy-duty trucks on the market will install guardrails or protective nets on the sides of the berths. The protective nets can provide certain protection for the passengers in minor collisions.

[0003] In some related technologies, guardrails or protective nets are installed on the sides of berths, which can provide protection under normal circumstances. However, when vehicles collide, people will hit the guardrails or protective devices, and the impact force may cause human bodies to be injured by other parts in the vehicle.

[0004] In addition, if a protective belt is used to restrain the human body on the berth, although the above-mentioned problem can be solved, it is extremely inconvenient for the occupants. Both getting on and off the bed need to be tied or opened, which limits the occupants' lying posture and reduces comfort.

[0005] Therefore, how to ensure active protection for the human body in the event of a vehicle collision while also being convenient for passengers to use under normal circumstances is an issue that needs to be addressed urgently. Summary of the invention

[0006] The embodiment of the present application provides an active protection berth to solve the problem in the related art that it is not possible to ensure active protection of the human body in the event of a vehicle collision, while also being convenient for occupants to use under normal circumstances.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The embodiment of the present application provides an active protection berth to solve the problem in the related art that it is not possible to ensure active protection of the human body in the event of a vehicle collision, while also being convenient for occupants to use under normal circumstances.

[0045] See also Figure 1-Figure 4 , an active protection sleeper, comprising: a sleeper body 1, a protection net 2, a safety belt 3, a guide bracket 4 and a safety belt active retractor 5;

[0046] The guide bracket 4 has a self-breaking ring 400, which is located above the berth body 1 and is used to be fixed on the wall of the cab facing the rear of the vehicle body, so as to form a space for passengers to rest; one end of the protective net 2 is installed on the side of the berth body 1 facing the front of the vehicle, and the other end is connected with the safety belt 3; the active safety belt retractor 5 is installed on the side of the berth body 1 facing the rear of the vehicle body, and is connected to the safety belt 3 passing through the self-breaking ring 400; the active safety belt retractor 5 is used to tighten the safety belt 3 and break the self-breaking ring 400 at the same time after receiving the collision signal, so that the safety belt 3 and the protective net 2 restrain the human body. The protective net 2 is made of a flexible material, such as fiber.

[0047] Since the guide bracket 4 is provided with a self-breaking ring 400, the guide bracket 4 is located above the berth body 1 and is used to be fixed on the wall of the cab facing the rear of the vehicle body; one end of the protective net 2 is installed on the side of the berth body 1 facing the front of the vehicle, and the other end is connected with the safety belt 3; the active safety belt retractor 5 is installed on the side of the berth body 1 facing the rear of the vehicle body, and is connected to the safety belt 3 passing through the self-breaking ring 400; so that when in use, when the occupant is resting normally, the protective net 2 stands on the side of the berth body 1 facing the front of the vehicle to prevent the occupant from falling, and the safety belt is placed above the occupant by using the guide bracket 4, which does not affect the occupant's lying rest and avoids affecting the comfort; when the vehicle collides, the active safety belt retractor 5 tightens the safety belt 3 and breaks the self-breaking ring 400 after receiving the collision signal, so that the safety belt 3 and the protective net 2 restrain the human body to prevent the human body from shaking and colliding with the impact force, thereby ensuring that the human body can be actively protected in the event of a vehicle collision, and it can also be convenient for the occupant to use it under normal circumstances.

[0048] In some preferred embodiments, the structure of the guide bracket 4 is configured as follows so that it has the function of breaking under force, referring to Figure 7 , as follows:

[0049] The guide bracket 4 includes a connection seat 401 and a self-breaking ring 400; the self-breaking ring 400 includes a ring, one side of the ring is fixedly connected to the connection seat 401, and the other end is provided with a shunting groove 402, and the ring is provided with breaking lines on both sides of the shunting groove 402. The shunting groove 402 is used to facilitate the placement of the safety belt 3 into the ring, and the ring guides the safety belt 3 while also lifting the safety belt 3 upwards, so as to form the above-mentioned space for the occupant to rest.

[0050] Among them, the ring is made of a hollow or solid plastic material. The setting of the fracture score line allows the safety belt 3 to act on the self-breaking ring 400. When a certain force is exceeded, the self-breaking ring 400 breaks from the fracture score line. Of course, the self-breaking ring 400 can also be provided with no fracture score line, but its material needs to be made of a thermoplastic elastomer that is easily broken by force. Thermoplastic elastomer is a mixed compound material with the bearing capacity and aging resistance of traditional cross-linked vulcanized rubber, and is not easy to break under static load. However, it has a poor plasticizing effect during molding, resulting in poor toughness, and is easy to break when impacted.

[0051] refer to Figure 4 and Figure 5 In some preferred embodiments, how to reel in the safety belt 3 and provide a force to break the self-breaking ring 400 is as follows:

[0052] The active seat belt retractor 5 comprises: a mounting frame 500, a slot 501, a rotating shaft 502, a transmission assembly 503, a driving member 508 and a control assembly;

[0053] The mounting frame 500 is enclosed to form a receiving space, and a first mounting surface is provided on the top thereof; a through slot 501 communicating with the receiving space is provided on the first mounting surface; a rotating shaft 502 is rotatably mounted in the receiving space, and is connected to the safety belt 3 passing through the through slot 501; a transmission assembly 503 is mounted on the second mounting surface of the mounting frame 500; a driving member 508 is mounted on the first mounting surface, and is in transmission connection with the rotating shaft 502 through the transmission assembly 503; a control assembly is connected to the driving member 508 and is used to receive a collision signal to drive the rotating shaft 502 to reel up the safety belt 3. The collision signal is sensed by a sensor provided on the vehicle, such as a vibration sensor and an acceleration sensor.

[0054] During actual use, the mounting frame 500 is installed on the side of the berth body 1 facing the rear of the vehicle body, and then the rotating shaft 502 is installed in the accommodating space; the driving member 508 is installed on the first mounting surface and is connected to the rotating shaft 502 through the transmission assembly 503; then the safety belt 3 is passed through the slot 501 and connected to the rotating shaft 502, and rolled up in the accommodating space.

[0055] Furthermore, there are many forms of the structure of the driving member 508 and the transmission assembly 503, such as friction transmission, chain transmission, gear transmission, belt transmission, ratchet transmission, crankshaft-connecting rod transmission, pneumatic transmission, hydraulic transmission, wire rope transmission, coupling transmission, spline transmission, etc., as long as they can drive the rotating shaft 502 to rotate. Therefore, a specific embodiment is given below, specifically:

[0056] The mounting frame 500 is provided with a mounting seat 507; the transmission assembly 503 includes a crown gear 504, a transmission rod 505 and a driving turbine 506; the crown gear 504 is connected to the output shaft of the driving member 508; the driving turbine 506 is installed on the rotating shaft 502; the transmission rod 505 is connected to the mounting frame 500 through the mounting seat 507, one end of the transmission rod 505 is meshed with the crown gear 504, and the other end is provided with a turbine rod meshed with the driving turbine 506.

[0057] The output shaft of the driving member 508 drives the crown gear 504 to rotate, and the crown gear 504 rotates the transmission rod 505, and the worm connected to the transmission rod 505 meshes with the driving turbine 506, so that the rotating shaft 502 rotates to reel the safety belt 3. This structure has a locking function by using the crown gear 504, the worm and the driving turbine 506 in coordination, and can generate a large torque to produce the effect of breaking the self-breaking ring 400. The model of the driving member 508 can be selected according to the needs.

[0058] The teeth of crown gear 504 are distributed on the end surface, and are generally used in mechanical speed change and reversing clutches, and are also widely used in toys. Its advantages are: small size, compact structure, large torque transmission, and as long as the axial positioning part is slightly designed, it can "slip" when overloaded, which has a self-protection effect.

[0059] In some preferred embodiments, during the use process, the number of the safety belts 3 is multiple and is spaced apart along the length direction of the protection net 2; the number of the active safety belt retractors 5 is multiple and is spaced apart along the length direction of the berth body 1 and is connected to the safety belts 3 one-to-one. Figure 1 , Figure 2 and Figure 3 The number of active seat belt retractors 5 is three, the number of seat belts 3 is three, and the number of corresponding guide brackets 4 is also three.

[0060] refer to Figure 4 In some preferred embodiments, in order to facilitate the storage of the safety belt 3 and the protection net 2 when not in use, the following settings are made:

[0061] The active protection sleeper also includes a storage box 6 located at the bottom of the sleeper body 1. The storage box 6 is provided with a through slot on the side facing the front of the vehicle, and the through slot is connected to the internal space of the storage box 6. One end of the protection net 2 is fixed in the storage box 6, and the other end is provided with a through slot to connect with the safety belt 3. The storage box 6 is made of aluminum material, and is formed into an aluminum shell with an internal space by stamping, and flanges are formed around it. The material of the storage box 6 can also be made of hard plastic to reduce weight.

[0062] Therefore, when in use, the active safety belt retractor 5 reels the safety belt 3 to bring the protective net 2 out of the accommodating box 6 ; when not in use, the protective net 2 is placed in the accommodating box 6 .

[0063] Furthermore, in order to facilitate the storage of the protective net 2 when it is not needed, the following settings are provided:

[0064] The housing box 6 is provided with a retracting member 7, which is connected to the protective net 2; when the active safety belt retractor 5 releases the safety belt 3, the protective net 2 is retracted into the housing box 6 for easy storage. The retracting member 7 can be a retracting structure driven by a motor, or an elastic structure; the elastic structure is used as an example for specific description below:

[0065] The protective net 2 is provided with a rim 8 around it; the pullback member 7 includes an elastic band 700, one end of the elastic band 700 is connected to the rim 8, and the other end is connected to the accommodating box 6. The rim 8 not only facilitates the connection with the elastic band 700, but also protects the protective net 2.

[0066] For further reference, Figure 4 In order to strengthen the pulling effect of the elastic structure, the pulling member 7 also includes a rotating wheel 701 and an elastic rope 702. The two rotating wheels 701 are arranged in the length direction of the accommodating box 6, and the two ends of the elastic rope 702 are respectively passed around the rotating wheels 701 and connected to the edge 8; the number of the elastic belts 700 is two, and they are distributed along the length direction of the accommodating box 6, and the elastic rope 702 is arranged parallel to the elastic belt 700.

[0067] Furthermore, in order to facilitate the installation of the accommodating box 6, it is also considered that it can be connected to the existing berth body 1 to achieve universality. The accommodating box 6 is detachably connected to the berth body 1. Figure 8 , wherein the accommodating box 6 is provided with a flange in contact with the bottom of the berth body 1, and a card slot 9 is provided around the flange. The bottom of the berth body 1 is provided with a hook 10 corresponding to the card slot 9, and the hook 10 is connected to the berth body 1 by bolts and screws, thereby realizing a detachable connection. In this embodiment, the hook 10 passes through the card slot 9 from the top of the flange and is bent and held against the bottom of the flange. Of course, other forms of detachable connection are also possible, such as connection using magnets, pin connection, etc.
