Description

Technical Field

[0001] The present disclosure relates to a pet safety belt, a pet safety system and a vehicle, and belongs to the technical field of pet safety protection in vehicles. Background Art

[0002] As the number of pet owners grows, pets are becoming an important part of the family travel experience. However, current safety design in the automotive industry primarily focuses on human occupants, and dedicated safety protection systems for pets have long been lacking. In everyday driving, pets are often placed in the back seat of a vehicle without proper restraints or guidance. When a vehicle brakes suddenly, collides, or makes a sharp turn, an unrestrained pet can move significantly due to inertia. This can lead to injuries such as collisions with internal components or collisions with the driver, causing secondary accidents.

[0003] Current car safety features, such as seat belts and airbags, are designed for humans and are not directly adaptable to pets. Currently, a design has been proposed that involves attaching the pet leash directly to the seat belt, restricting the pet's movement through a strong restraint. However, given the active nature of pets, this strong restraint method deprives them of space to move, potentially leading to stress and rebellion.

[0004] Therefore, there is room for improvement in the pet safety protection of existing cars, and there is an urgent need to develop a pet safety protection device that can adapt to the vehicle structure. Summary of the Invention

[0005] In order to solve the above technical problems, the present disclosure proposes a pet safety belt, a pet safety system and a vehicle, which can achieve targeted protection for the safety of pets riding in vehicles. While ensuring that pets have a reasonable space for activities to avoid stress reactions, by means of adaptive linkage with the vehicle's existing safety system, they can effectively restrain pets in emergency situations to prevent them from causing harm to themselves and passengers in the vehicle due to large-scale movement due to inertia, thereby achieving a balance between the pet's activity needs and collision protection effects, and improving the safety of pets riding in vehicles.

[0006] Specifically, the first aspect of the present disclosure proposes a pet safety belt, which can be detachably installed on a vehicle. The pet safety belt includes: a first belt body, a first connecting portion is provided on the first belt body, so that the first belt body can be detachably installed on the seat belt of the vehicle via the first connecting portion; and a second belt body, one end of the second belt body is provided with a second connecting portion, so that the second belt body can be slidably connected to the first belt body via the second connecting portion, and the other end of the second belt body can be connected to a pet.

[0007] The pet safety belt with the above configuration detachably connects to the vehicle seat belt via the first connecting portion on the first belt body, achieving flexible adaptation to existing vehicle safety structures. It can be quickly installed and removed without requiring additional vehicle modifications, thus improving ease of use. Simultaneously, the second belt body slidably connects to the first belt body via the second connecting portion, and the other end can be connected to the pet. Thus, the first belt body secures the pet to the vehicle, providing basic restraint, similar to the safety protection provided by seat belts for humans. Furthermore, the sliding nature of the second belt body relative to the first belt body allows the pet to move freely, avoiding stress reactions that could result from excessive restraint. While ensuring the pet's basic freedom of movement, the risk of injury or interference with driving due to significant displacement during sudden braking or collisions is reduced, effectively balancing pet comfort and vehicle safety.

[0008] Preferably, in the pet safety belt of the first aspect, the first connecting portion of the first belt body includes a buckle and a locking tongue extending from the first belt body in opposite directions to each other, the buckle is for inserting and locking a seat belt tongue of a seat belt, and the locking tongue can be inserted into and locked to the seat belt buckle of the seat belt.

[0009] The pet safety belt with the above configuration, through the buckle and tongue extending in opposite directions from the first connecting portion of the first belt body, can achieve bidirectional compatibility with the vehicle's existing seat belt system. This not only ensures the stability of the connection between the first belt body and the vehicle seat belt, but also allows for flexible adaptation to the locking structures of different vehicle seat belts, enhancing the versatility of the pet safety belt. Furthermore, by leveraging the vehicle seat belt's inherent locking structure, the first belt body can be quickly installed and locked to the vehicle without the need for additional complex fixing structures, improving assembly efficiency and facilitating disassembly, further ensuring the reliability and convenience of the pet safety belt during use.

[0010] Preferably, in the pet safety belt described in the first aspect, the first belt body includes a main belt and a branch belt branching from the main belt, the main belt has a length corresponding to the rear seat of the vehicle so as to be arranged along the left and right directions of the rear seat, and the buckle is provided on the main belt, the branch belt extends from the main belt in a direction crossing the main belt, and the locking tongue is provided at the end of the branch belt, and the second belt body is connected to the main belt via a second connecting portion.

[0011] Alternatively, preferably, in the pet safety belt described in the first aspect, the first belt body includes a main belt, the main belt has a length corresponding to the rear seat of the vehicle so as to be arranged in the left-right direction of the rear seat, the buckle and the locking tongue are provided on the main belt, and the second belt body is connected to the main belt via a second connecting portion.

[0012] In the pet safety belt with the above configuration, the main strap of the first belt body is arranged along the left and right sides of the rear seats, providing a stable sliding foundation for the second belt body, ensuring a reasonable range of movement space for pets in the rear seats. When a branch strap is included, the branch strap provides a mating margin between the locking tongue and the seat belt buckle. For seat belt buckles in different locations on any vehicle model, the flexible branch strap can reliably and easily mate the locking tongue to the seat belt buckle. The branch strap also cooperates with the main strap to bear force, more evenly distributing the force when the pet is pulled, thereby improving the convenience and reliability of the connection with the vehicle's original seat belt system. When there is no branch belt, that is, the locking tongue is directly formed on the main belt, the branch components are reduced, the overall structure is simpler, the number of components is small, it saves more space when stored, and the volume is smaller after folding. Moreover, as long as the length of the main belt is sufficient, even if there is no branch belt, the main belt itself can provide the matching margin between the locking tongue and the seat belt buckle, which makes it easy to install the locking tongue to the seat belt buckle in different positions of any vehicle model, and can also achieve excellent installation operability.

[0013] Preferably, in the pet safety belt described in the first aspect, the main belt of the first belt body is provided with a plurality of ratchets, and the plurality of ratchets are arranged in the length direction of the main belt, and the second connecting part of the second belt body includes: a locking pin, the locking pin having a normal position that is not engaged with the ratchets and a locked position that is engaged with the ratchets; and a driving part, the driving part drives the locking pin in response to a predetermined signal to switch between the normal position and the locked position, when the locking pin is in the normal position, the second belt body can move along the main belt of the first belt body; when the locking pin is in the locked position, the second belt body is fixed to the main belt and cannot move along the main belt.

[0014] In the pet safety belt having the above configuration, the main strap of the first strap body is provided with a plurality of ratchets arranged along its length, and the second connecting portion is adapted to switch between a normal position and a locked position via a rotatable latch pin that cooperates with a drive unit. Therefore, in the normal state, when the latch pin is not engaged with the ratchets, the second strap body can slide freely along the main strap, providing the pet with room to move left and right based on the length of the main strap, satisfying the pet's natural movement needs in the rear seat and avoiding the discomfort caused by fixed restraint. In the event of an emergency such as a vehicle collision, rollover, or sudden braking, the drive unit, in response to a predetermined signal, such as a collision signal from the vehicle safety system, drives the latch pin to the locked position, tightly engaging the ratchets and instantly securing the second strap body to the main strap. This instant locking effectively restricts the pet's left and right movement during violent vehicle movements, preventing the pet from inertia from striking vehicle seats, doors, windows, and other components, or from significant displacement within the vehicle, potentially causing injury. This significantly enhances the safety of the pet in emergency situations.

[0015] Preferably, the pet safety belt described in the first aspect further comprises a pet carrier, and the other end of the second belt body is detachably connected to the pet carrier.

[0016] The pet safety harness with the above configuration, thanks to the pet carrier, distributes the restraining force more evenly across multiple areas of the pet's body, avoiding discomfort or injury caused by localized tightening. Furthermore, the detachable connection allows the carrier to be removed separately when the harness is no longer needed, allowing it to be used for daily traction or other situations. If the pet carrier becomes worn, it can be replaced separately, eliminating the need to replace the entire harness, thus reducing maintenance costs.

[0017] Preferably, in the pet safety belt described in the first aspect, the one end of the second belt body and the second connecting portion are detachable structures.

[0018] According to the pet safety belt with the above configuration, one end of the second belt body and the second connecting portion are detachable. Therefore, upon arrival at the destination, the second belt body can be removed from the connecting portion and used directly as a pet leash, such as a dog leash, eliminating the need to carry additional pet traction tools, simplifying travel equipment and enhancing the product's versatility. Furthermore, users can flexibly replace different types of second belt bodies as needed, such as replacing a dedicated second belt body with an everyday dog ​​leash, or replacing second belt bodies with different appearances, colors, and styles. This allows the pet safety belt to adapt to a variety of belt types, meeting the dual needs of in-vehicle restraint and out-of-vehicle traction, as well as user customization.

[0019] The pet safety belt and technical effects of the first aspect of the present disclosure have been described above, and the second aspect of the present disclosure will be described below.

[0020] A second aspect of the present disclosure provides a pet safety system for a vehicle, comprising: a plurality of seat belts arranged on rear seats of the vehicle; a pet safety belt according to the first aspect connected between the seat belts and the pet; a camera provided in the vehicle for identifying the position of the pet on the rear seat; and a control unit which, upon receiving a signal that the vehicle has collided, controls the seat belt corresponding to the position of the pet based on the position of the pet identified by the camera to tighten the seat belt.

[0021] The pet safety system with the above configuration integrates the vehicle's existing rear seat belts, the pet safety belts described in the first aspect, an in-vehicle camera, and a control unit to achieve intelligent and precise protection for pets while riding in a vehicle. Upon receiving a vehicle collision signal, the control unit tightens the corresponding seat belt based on the pet's position, transmitting the restraining force to the pet through the pet safety belt. This quickly limits the pet's movement and prevents unplanned collisions within the vehicle. Furthermore, by leveraging the vehicle's existing seat belt tightening function, effective pet restraint can be achieved without the need for a complex additional power mechanism, reducing system complexity and cost.

[0022] Preferably, the pet safety system of the second aspect further includes a plurality of sensors, which are arranged on each seat of the rear seat and sense the weight of the seated pet. The control unit adjusts the tightening force of the seat belt in the tightening state based on the weight of the pet sensed by the sensor.

[0023] With the aforementioned pet safety system, multiple sensors placed in each rear seat work in conjunction with the control unit to further enhance the accuracy and safety of protection by sensing the pet's weight and adjusting the seatbelt tension. The sensors detect the pet's weight distribution across each seat in real time, providing the control unit with quantified weight data. Based on this data, the control unit adjusts the tensioning force, achieving differentiated restraint for pets of different sizes. For large, heavy pets, the control unit can control the seatbelt to apply greater tension to prevent the pet from escaping due to insufficient restraint. For smaller, lighter pets, the tensioning force is reduced accordingly, ensuring effective restraint while preventing excessive force from causing injuries such as squeezing or strangulation. Moreover, when a pet straddles multiple seats, the control unit can differentiate and distribute the seat belt tightening force of the corresponding seats in real time by using sensors to sense the weight proportion borne by each seat, so that the tightening force in areas with a high weight ratio is greater, and the tightening force in areas with a low weight ratio is smaller, so that the overall restraint force matches the weight distribution of the pet, which not only ensures the stability of the overall restraint, but also avoids local over-tightening, and balances the effectiveness of the restraint with the comfort of the pet.

[0024] A third aspect of the present disclosure provides a vehicle equipped with the pet safety system according to the second aspect. As the vehicle is equipped with the pet safety system according to the second aspect, the above-mentioned technical effects can also be achieved.

[0025] The above generally describes the technical solutions of the pet safety belt, pet safety system, and vehicle of the present disclosure. Below, the technical solutions of the present disclosure will be more easily understood by describing the details with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] Hereinafter, the technical solutions of the present invention will be more clearly explained by describing specific embodiments of the present invention with reference to the accompanying drawings.

[0066] It should be noted that the drawings in the present invention are merely schematic diagrams for the purpose of clearly illustrating the parts related to the solutions of the present invention, and do not show some non-essential parts that may exist. Therefore, these drawings should not be understood as limiting the present invention, and they may differ from the actual structure when used. In addition, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", etc. that may appear in the following description to indicate direction or position are for the purpose of convenience of explanation and are not restrictive. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0067] <First embodiment>

[0068] Figure 1-Figure 3 A pet safety belt 10 according to a first embodiment of the present disclosure is shown, wherein: Figure 1 is a schematic diagram of a pet safety belt 10 according to a first embodiment of the present disclosure; Figure 2 1 is a schematic diagram of the connection portion between the first belt body 20 and the second belt body 30 in the pet safety belt 10 according to the first embodiment of the present disclosure; Figure 3 FIG. 1 is a schematic diagram of the pet safety belt 10 according to the first embodiment of the present disclosure in use.

[0069] like Figure 1 and Figure 3 As shown, the pet safety belt 10 of this embodiment is used in a vehicle 1 and can be detachably mounted on a vehicle seat 60 of the vehicle 1. When not in use, the pet safety belt 10 can be stored in a storage space of the vehicle, such as a trunk, glove box, or a storage net bag behind a seat. Figure 3 The pet safety belt 10 is installed in a vehicle and is used to safely restrain a pet 50. The main body of the pet safety belt 10 is made of a soft, high-strength material, not limited to fabric, plastic, resin, etc.

[0070] Pet safety belt 10 Figure 1 The diagram includes: a first belt body 20, on which a first connecting portion 21 is provided, so that the first belt body 20 can be detachably mounted to the seat belt 61 of the vehicle 1 via the first connecting portion 21; and a second belt body 30, one end of which is provided with a second connecting portion 31, so that the second belt body 30 can be slidably connected to the first belt body 20 via the second connecting portion 31, and the other end of the second belt body 30 can be connected to the pet 50.

[0071] The pet safety belt 10 of this embodiment is detachably connected to the vehicle seat belt 61 via the first connecting portion 21 on the first belt body 20, enabling flexible adaptation to the safety structure of existing vehicles 1. It can be quickly installed and removed without requiring additional modifications to the vehicle 1, enhancing ease of use. Furthermore, the second belt body 30 is slidably connected to the first belt body 20 via the second connecting portion 31, and its other end can be connected to the pet 50. Thus, the first belt body 20 securely fastens the vehicle 1, providing basic restraint for the pet, similar to the safety protection provided by the seat belt 61 for humans. Furthermore, the sliding nature of the second belt body 30 relative to the first belt body 20 provides sufficient space for the pet to move, preventing stress reactions that could result from excessive restraint. While ensuring basic freedom of movement for the pet 50, it also reduces the risk of injury or disruption to driving caused by significant displacement during sudden braking or collisions, effectively balancing pet comfort and safety.

[0072] In the pet safety belt 10 of this embodiment, Figure 1 and Figure 3 As shown, the first belt body 20 includes a main belt 24 and a branch belt 26 branching from the main belt 24. The main belt 24 has a length corresponding to the vehicle seat (rear seat) 60 of the vehicle 1, so that it is arranged in the left-right direction of the rear seat. The branch belt 26 extends from the main belt 24 in a direction intersecting the main belt 24. The number of branch belts 26 is not limited to the two shown in the figure; for example, there can be three corresponding to each seat or only one provided in the middle. To make the pet safety belt 10 relatively flat during use, the branch belt 26 preferably branches off from the main belt 24 in the direction toward the corresponding seat belt buckle 63 of the seat belt 61.

[0073] Regarding the first connecting portion 21 of the first belt body 20 of the pet safety belt 10 of this embodiment, as shown in FIG. Figure 1 As shown, a lock buckle 22 and a lock tongue 23 extending in opposite directions may be used. The structures of the lock buckle 22 and the lock tongue 23 may be the same as the conventional seat belt lock tongue 62 and seat belt lock buckle 63 of the seat belt 61, and are not described in detail here.

[0074] In this embodiment, if Figure 1 As shown, the buckle 22 of the first connecting portion 21 is provided on the main belt 24 of the first belt body 20. The number of buckles 22 may correspond to the three seat belts 61 of the rear seat, and the buckles 22 are spaced apart from each other so as to engage with the seat belt tongues 62 of the three seat belts 61. The tongue of the first connecting portion 21 is provided at the end of the branch belt 26 of the first belt body 20 and can be inserted into and locked to the seat belt buckle 63 of the seat belt 61.

[0075] The pet safety belt 10 of this embodiment, through the buckle 22 and tongue 23 extending in opposite directions from the first connecting portion 21 of the first belt body 20, can achieve bidirectional compatibility with the existing vehicle seat belt system. This not only ensures the stability of the connection between the first belt body 20 and the vehicle seat belt 61, but also allows for flexible adaptation to the locking structures (seat belt tongue 62, seat belt buckle 63) of different vehicle seat belts 61, thereby enhancing the versatility of the pet safety belt 10. Furthermore, by leveraging the inherent locking structure of the vehicle seat belt 61, the first belt body 20 can be quickly installed and locked to the vehicle 1 without the need for a complex additional fixing structure, improving assembly efficiency and facilitating disassembly operations, further ensuring the reliability and convenience of the pet safety belt 10 during use. Moreover, since the first belt body 20 includes the main belt 24 and the branch belt 26, the branch belt 26 provides a fitting margin for the fitting between the locking tongue 23 and the seat belt buckle 63. For the seat belt buckle 63 at different positions of any vehicle model, the soft branch belt 26 can be used to reliably and easily fit the locking tongue 23 to the seat belt buckle 63. Moreover, the branch belt 26 can also cooperate with the main belt 24 to bear force, and can more evenly disperse the force when the pet 50 is pulled, thereby improving the convenience and reliability of connection with the vehicle's original seat belt system.

[0076] Below, we will refer to Figure 2 The second connecting portion 31 of the second belt body 30 of the pet safety belt 10 of this embodiment will be described.

[0077] The second belt body 30 of the pet safety belt 10 is connected to the main belt 24 of the first belt body 20 via the second connecting portion 31 and can move freely along the main belt 24, thereby providing space for the pet 50 to move. Figure 2 As shown, it includes a second connecting portion body 32 and a rotating shaft 33. The main belt 24 passes through the second connecting portion body 32 and the rotating shaft 33, and there is a gap between the second connecting portion body 32 and the rotating shaft 33. Therefore, the second connecting portion 31 can move freely along the main belt 24. The rotating shaft 33 of the second connecting portion 31 is provided with an outwardly protruding locking pin 34 and an integrated micro motor 35. Therefore, it can rotate relative to the second connecting portion body 32 under the drive of the micro motor 35, so that the position of the locking pin 34 changes with the rotation.

[0078] The main belt 24 of the first belt body 20 of the pet safety belt 10 is as shown in FIG. Figure 2As shown, a plurality of ratchet teeth 25 may be provided on one of the surfaces, i.e., the surface facing the rotating shaft. The plurality of ratchet teeth 25 are arranged in the longitudinal direction of the main belt 24. The space between two adjacent ratchet teeth 25 constitutes an engagement space for the locking pin 34, so that the locking pin 34 can enter the engagement space and be locked with the ratchet teeth 25. When, for example, a vehicle collision occurs, the motor 35 can be started in response to the vehicle collision signal of the collision, thereby driving the rotating shaft 33 as shown in FIG. Figure 2 As shown by the arrow, the locking pin 34 is rotated Figure 2 The normal position shown is never engaged with the ratchet 25 ( Figure 2 On the left side, the second belt body 30 can move along the main belt 24) and switch to the locking position (engaged with the ratchet 25) Figure 2 On the right side, the second belt body 30 cannot move along the main belt 24).

[0079] The pet safety belt 10 of this embodiment is provided with a plurality of ratchets 25 arranged along the length direction on the main belt 24 of the first belt body 20, and a rotatable locking pin 34 that can be switched between a normal position and a locked position is provided on the second connecting portion 31 of the second belt body 30. Therefore, in the normal state where the locking pin 34 is not engaged with the ratchets 25, the second belt body 30 can slide freely along the main belt 24, providing the pet 50 with left and right movement space based on the length of the main belt 24, meeting the natural movement needs of the pet 50 in the rear seat, and avoiding the discomfort caused by fixed restraints. When the vehicle collides, rolls over, or brakes suddenly, the motor 35 responds to a predetermined signal, such as a collision signal from the vehicle safety system, to drive the locking pin 34 to switch to the locked position, tightly engaging with the ratchet 25, so that the second belt body 30 is instantly fixed to the main belt 24. This instant locking effectively limits the pet's left and right movement when the vehicle moves violently, preventing the pet from colliding with seats, doors, windows and other parts in the car due to inertia, or causing injury to itself due to large displacement in the car, significantly improving the safety of pets in emergency scenarios.

[0080] like Figure 3 As shown, the pet safety harness 10 of this embodiment also includes a pet carrier 40. The other end of the second belt body 30 is detachably connected to the pet carrier 40 via a connecting buckle 36. The provision of the pet carrier 40 distributes the restraining force more evenly across multiple areas of the pet's body, avoiding discomfort or injury caused by localized tightening. Furthermore, the detachable connection allows the pet carrier 40 to be removed separately when the safety harness is no longer needed and used as a tool for daily traction or other situations. If the pet carrier becomes worn, it can be replaced separately, eliminating the need to replace the entire safety harness, reducing maintenance costs.

[0081] According to the pet safety belt 10 of this embodiment, it can achieve targeted protection for the safety of pets riding in a vehicle. While ensuring that the pet 50 has a reasonable space for activities to avoid stress reactions, it can effectively restrain the pet 50 in an emergency situation by means of adaptive linkage with the vehicle's existing safety system, preventing the pet 50 from causing harm to itself and the passengers in the vehicle due to large-scale movement due to inertia, thus achieving a balance between the pet's activity needs and the collision protection effect, and improving the safety of pets riding in a vehicle.

[0082] <Second embodiment>

[0083] Figure 4-Figure 6 The second embodiment of the present disclosure is shown in FIG. The second embodiment relates to a pet safety system for a vehicle 1 , to which the pet safety belt 10 of the first embodiment is applied.

[0084] The pet safety system of the vehicle 1 of this embodiment includes: a plurality of seat belts 61 arranged on the rear seat 60 of the vehicle 1; a pet safety belt 10 connected between the seat belts 61 and the pet 50; a camera 70 provided in the vehicle for identifying the position of the pet 50 on the rear seat 60; and a control unit (not shown, for example, it can be a central control unit of the vehicle), which, when receiving a signal that the vehicle has collided, controls the seat belt 61 corresponding to the position of the pet 50 based on the position of the pet 50 identified by the camera 70, so that the seat belt 61 is in a tightened state.

[0085] Specifically, see Figure 5 When the camera 70 recognizes that the pet 50 is in a relatively right position among the three seats in the rear seat 60, at this time, when the control unit receives a signal that the vehicle has collided, the second seat belt 612 corresponding to the middle seat in the relatively right position and the third seat belt 613 of the right seat among the three seat belts 61 are tightened. Specifically, the corresponding second tightening mechanism 652 and the third tightening mechanism 653 in the tightening mechanism 65 (such as a seat belt pretensioner) are activated to tighten the corresponding seat belts 612 and 613.

[0086] On the other hand, see Figure 6 When the camera 70 recognizes that the pet 50 is straddling three seats in the rear seat 60, at this time, when the control unit receives a signal that the vehicle has collided, the first seat belt 611, the second seat belt 612 and the third seat belt 613 of the three seat belts 61 are tightened. Specifically, the corresponding first tightening mechanism 651, the second tightening mechanism 652 and the third tightening mechanism 653 in the tightening mechanism 65 are all activated to tighten the corresponding seat belts 611, 612, 613.

[0087] The pet safety system of this embodiment integrates the vehicle's existing rear seat belts 61, the pet safety belt 10, an in-vehicle camera 70, and a control unit to provide intelligent and precise protection for pets while riding in a vehicle. Upon receiving a vehicle collision signal, the control unit tightens the corresponding seat belt based on the pet's position. This restraining force is then transmitted to the pet through the pet safety belt, quickly limiting the pet's movement and preventing unplanned collisions within the vehicle. Furthermore, by leveraging the vehicle's existing seat belt tightening function, the system effectively restrains the pet without the need for a complex additional power mechanism, reducing system complexity and cost.

[0088] Also, see Figure 5 and Figure 6 The pet safety system of this embodiment further includes a plurality of sensors 64. These sensors 64 may be weight sensors, located on each rear seat, and include a first sensor 641, a second sensor 642, and a third sensor 643. These sensors 64 sense the weight of the seated pet 50 and transmit this data to the control unit. The control unit adjusts the tightening force of the seat belt 61 based on the weight of the pet 50 sensed by the sensors 64.

[0089] In this embodiment, the tightening force can be expressed by the formula F=m·a+F1, wherein F represents the tightening force of the corresponding tightening mechanism 65, m represents the measured value of the weight sensed by the corresponding sensor 64, a represents the peak acceleration during the collision (which can be measured by the vehicle acceleration sensor), and F1 represents the preset value of the pre-tightening force of the tightening mechanism 65 of the seat belt 61 of each seat, wherein, considering the chest pressure value of the pet 50, it is initially set to 600N. <F1<800N。

[0090] Accordingly, in Figure 5 In the case shown, since the pet 50 is relatively positioned to the right, only the second sensor 642 and the third sensor 643 are activated, and sense the weight borne by the corresponding parts, and then adjust the tightening force applied by the second tightening mechanism 652 to the second seat belt 612 and the tightening force applied by the third tightening mechanism 653 to the third seat belt 613 according to the above formula. Figure 6 In the case shown, since the pet 50 spans three seats, the first sensor 641, the second sensor 642 and the third sensor 643 are all activated to sense the weight borne by the corresponding parts, and then adjust the tightening force applied by the first tightening mechanism 651 to the first seat belt 611, the tightening force applied by the second tightening mechanism 652 to the second seat belt 612, and the tightening force applied by the third tightening mechanism 653 to the third seat belt 613 according to the above formula.

[0091] This embodiment of the pet safety system utilizes multiple sensors 64 positioned in each seat of the rear seat 60, working in conjunction with the control unit. By sensing the pet's weight and adjusting the seatbelt tension, the system further enhances the accuracy and safety of protection. Sensors 64 provide real-time information on the weight distribution of the pet 50 across each seat, providing the control unit with quantified weight data. Based on this data, the control unit adjusts the tensioning force, achieving differentiated restraint for pets of different sizes. For large, heavy pets, the control unit can control the seatbelt to apply greater tension to prevent the pet from escaping due to insufficient restraint. For smaller, lighter pets, the tensioning force is reduced accordingly, ensuring effective restraint while preventing excessive force from causing injuries such as crushing or strangulation. Moreover, when the pet 50 straddles multiple seats, the sensor 64 senses the weight proportion borne by each seat, and the control unit can differentiate and distribute the seat belt tightening force of the corresponding seats in real time, so that the tightening force in the area with a high weight ratio is greater, and the tightening force in the area with a low weight ratio is smaller, so that the overall restraint force matches the weight distribution of the pet, which not only ensures the stability of the overall restraint, but also avoids local over-tightening, and balances the effectiveness of the restraint and the comfort of the pet.

[0092] <Third embodiment>

[0093] Figure 7 The third embodiment of the present disclosure is also a pet safety belt 10 , which differs from the pet safety belt 10 of the first embodiment only in the configuration of the first belt body 20 . The remaining configurations are the same as those of the first embodiment, and therefore, only the different portions will be described below.

[0094] like Figure 7 As shown, the first belt body of the pet safety belt 10 of this embodiment includes only the main belt 24 and does not include the branch belt 26 of the first embodiment. The main belt 24 has a length corresponding to the rear seat of the vehicle so as to be arranged in the left and right direction of the rear seat. The buckle 22 and the locking tongue 23 are both provided on the main belt.

[0095] Since the pet safety belt 10 of this embodiment does not have a branch belt and the locking tongue 23 is formed directly on the main belt, the branch components are reduced, the overall structure is simpler, the number of components is reduced, and it is more space-saving when stored and has a smaller volume when folded. Moreover, as long as the main belt 24 is long enough, even without a branch belt, the main belt itself can provide a matching margin between the locking tongue 23 and the seat belt buckle, making it easy to install the locking tongue 23 to the seat belt buckle in different positions on any vehicle model, and also achieving excellent installation operability.

[0096] <Other embodiments>

[0097] Although the second strap body of the pet safety belt 10 is shown in the above embodiment as having a second connecting portion integrally provided at one end, this is not restrictive. The second strap body and the second connecting portion may be detachable. The detachable structure may be a buckle, a hook and loop, a lock, or the like, and is not limited herein.

[0098] When one end of the second belt body and the second connecting portion are detachable, for example, after the vehicle arrives at its destination, the second belt body can be removed from the second connecting portion and used directly as a pet leash, such as a dog leash. This eliminates the need to carry additional pet traction tools, simplifies travel equipment, and enhances the product's versatility. Furthermore, users can flexibly replace different types of second belt bodies as needed, such as replacing a dedicated second belt body with an everyday dog ​​leash, or replacing second belt bodies with different appearances, colors, and styles. This allows the pet safety belt to adapt to a variety of belt types, meeting the dual needs of in-vehicle restraint and out-of-vehicle traction, as well as user customization.

[0099] In addition, although not shown in the above embodiment, the branch belt of the first belt body of the pet safety belt may have a length adjustment buckle so that the length can be adjusted as needed.

[0100] In addition, although not shown in the above embodiment, the second belt body of the pet safety belt may be provided with an elastic portion or a length adjustment buckle, so that the length can also be adjusted.

[0101] In addition, although the pet carrier is shown as being separate from the second belt body in the above embodiment, the pet carrier may be integrally formed at the other end of the second belt body.

[0102] In addition, in the above embodiment, the second connecting portion of the second belt body is driven by a motor. However, the driving portion is not limited to a motor and may also be an electromagnetically controlled spring. Furthermore, the locking pin is not limited to switching between the normal position and the locked position by rotation. For example, the locking pin may be hidden in the rotating shaft 33 when in the normal position and extend from the rotating shaft when in the locked position.

[0103] In addition, in the above embodiment, the pet safety belt is described as being used with three locking tongues and buckles attached to three seat belts. However, this is not restrictive. For example, if there is a passenger in the rear seat of the vehicle, such as one passenger, the pet safety belt can be attached to two seat belts using only two locking tongues and buckles. Even if there are two passengers, the pet safety belt can be attached to only one seat belt using only one locking tongue and buckle.

[0104] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
