Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and in particular to a vehicle-mounted fitness device. Background Technology

[0002] With the rapid development of autonomous driving technology (especially Level 4 and Level 5 fully autonomous driving technology), the intelligence of automobiles is constantly being upgraded, eventually achieving fully driverless operation. Cars are also gradually evolving from simple means of transportation into mobile homes for humans. At the same time, people are spending increasingly more time in their cars, and prolonged sitting can damage people's health, most commonly causing lumbar and cervical spondylosis and frozen shoulder.

[0003] In Chinese Invention Patent Application No. 202510630800.X, the applicant disclosed a portable stretching exercise device that can be quickly fixed inside a car as needed, enabling people to exercise inside the vehicle. However, this portable stretching exercise device suffers from problems in the in-vehicle environment, including a short stretching range and an excessively long design that is inconvenient to deploy. Therefore, it is necessary to further improve the existing portable stretching exercise device to further shorten its length while increasing the stretching range. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a vehicle-mounted fitness device, comprising an elastomer assembly, a slider, a movable pulley, a cable, and a cable connector. The elastomer assembly consists of several elastic elements, one end of which is fixedly connected to the slider. The movable pulley is mounted on the slider. The cable passes through a groove on the outer circumference of the movable pulley, and one end of the cable is fixedly connected to the cable connector. The cable connector has a ring. Furthermore, similar connectors suitable for detachable connections, such as buckles and clasps, can also be used in this invention.

[0005] The vehicle-mounted fitness device of the present invention has an elastic element end that is not connected to the slider that is directly fixed to any component on the vehicle body as needed, and a cable end that is not connected to the cable connector that is directly fixed to any component on the vehicle body as needed. In use, the user pulls the cable through the cable connector, the cable pulls the movable pulley, and the movable pulley rotates itself, driving the slider to move, and the slider drives the elastic component to stretch. Under the action of the movable pulley, the distance the cable moves is always twice the distance the slider moves, thus achieving the invention objective of increasing the exercise stroke and shortening the length of the vehicle-mounted fitness device.

[0006] Furthermore, the vehicle-mounted fitness device also includes a housing assembly, which comprises a first housing and a second housing. The housing assembly contains a first cavity for accommodating the elastomer assembly, the slider, and the movable pulley; several second elastic element mounting slots for fixing the other end of the elastic element; and a cable through-slot for accommodating the cable. The elastic element has bosses at both ends, and the slider has a first elastic element mounting slot. The elastic element is fixed to the second elastic element mounting slots of the housing assembly and the first elastic element mounting slots of the slider via the bosses. The cable passes through the cable through-slot and is fixedly connected to a cable connector. Additionally, latex tubing, silent springs, or other components that provide damping force can all be used as the elastic element of this invention. When using different parts or components as the elastic element, within the scope of existing technology, corresponding adjustments can be made to the structure of the housing assembly and the slider for fixing the elastic element.

[0007] Furthermore, in order to sense the tension of the cable and transmit the tension signal to the vehicle system, the vehicle fitness device also includes a force sensor assembly. The housing assembly is provided with a force sensor assembly mounting slot. The end of the cable that is not connected to the cable connecting buckle is fixedly connected to the force sensor assembly. The force sensor assembly is located inside the force sensor assembly mounting slot on the housing assembly.

[0008] Furthermore, to reduce cable wear when the cable needs to move and turn, the vehicle-mounted fitness device also includes a fixed pulley assembly and a bearing positioning block. The fixed pulley assembly includes a fixed pulley and a pair of bearings mounted on the fixed pulley. The fixed pulley assembly is located at the bend in the cable path. The fixed pulley assembly and the bearing positioning block are mounted on the housing assembly. The cable passes through the groove on the outer circumference of the fixed pulley and then passes through the cable through the cable slot to be fixedly connected to the cable connecting buckle.

[0009] Furthermore, in order to sense the rotation angle of the fixed pulley in real time and transmit the angle signal to the vehicle system to calculate the travel of the cable, the vehicle fitness equipment also includes an angle sensor assembly. The housing assembly is provided with an angle sensor assembly mounting slot, and the angle sensor assembly is installed in the angle sensor assembly mounting slot on the housing assembly.

[0010] Furthermore, the housing assembly also includes a plurality of screws, the first housing has a plurality of threaded holes, the second housing has a plurality of screw mounting holes, and the first housing and the second housing are connected by screws.

[0011] Furthermore, the vehicle-mounted fitness device also includes a motion component, which includes a buckle, a shoulder strap, and a handle. The shoulder strap connects the handle and the buckle. The buckle is detachably connected to a ring on a cable connector. Meanwhile, similar connectors to the buckle, such as snap fasteners, clasps, and other known movable connectors, can be used in this invention.

[0012] Furthermore, the vehicle-mounted fitness device also includes a motion component, which includes a plurality of buckles and a shoulder strap. The plurality of buckles are disposed at the ends of the shoulder strap, and one of the buckles disposed at the ends of the shoulder strap forms a detachable connection with a ring on a cable connection buckle. Meanwhile, similar connectors to the buckles, such as buckles, clasps, and other known movable connectors, can be used in this invention.

[0013] Furthermore, the vehicle-mounted fitness device also includes a locking pin, and the slider is provided with a locking pin mounting hole and a movable pulley mounting groove. The locking pin is mounted on the slider through the locking pin mounting hole, and the movable pulley is mounted in the movable pulley mounting groove of the slider through the locking pin.

[0014] Furthermore, in order to stop the cable rebound and pre-tighten the cable, the cable connector buckle is also provided with a stop surface.

[0015] The vehicle-mounted fitness device of the present invention has the following advantages: 1. The vehicle-mounted fitness device of the present invention achieves the purpose of increasing the exercise stroke and shortening the length of the vehicle-mounted fitness device by setting a movable pulley on the slider, and the distance the cable moves under the action of the movable pulley is always twice the distance the slider moves.

[0016] 2. The vehicle-mounted fitness device of the present invention can sense the tension of the cable and calculate the cable stroke by means of the force sensor component and the angle sensor component installed in the housing assembly, and transmit fitness data to the vehicle system in real time, so that users can keep track of fitness data in real time.
